Space Development Futures: Spacefaring Infrastructures of Indifferently Spacefaring Civilizations

How do we go about crafting a spacefaring civilization? Nick Nielsen has been exploring the issues involved in terms of the choices cultures make and their conception of their future. Change the society and you change the outcome, with huge ramifications for our potential growth off-planet and on. The history of so-called ‘futurism’ tells us that visions of human potential differ according to the desirability (or lack of it) of deploying resources to space research, and it is a telling fact that many analyses extant today leave space out of the equation altogether. Have a look, then, at possible civilizations, their outcomes dictated by the assumptions they draw on as they attempt to pass through a bottleneck defined by a planetary society negotiating its relationship with the cosmos.

1. Space Infrastructure Architectures

Some years ago I wrote The Infrastructure Problem (2014), in which I touched upon the different spacefaring infrastructure architectures that would result from different admixtures of scientific research, technological development, and practicable engineering. Some years after I revisited some of these themes in The Return of the Space Settlement Vision (2017), especially the difference between the minimal space development architecture of Zubrin and Musk, and the maximal space development architecture of Wernher von Braun, Gerard K. O’Neill, and Bezos. These are the two most obvious alternative architectures for space development, but not the only two possibilities; in what follows I will inquire into the possibilities for qualitatively distinct space development as this development reflects the priorities of the society that designs, funds, and builds space infrastructure.

The choice between space development architectures is not merely a question of how best to get to Mars, or to some other destination; the question of space development architectures extrapolated to its greatest reach converges on the kind of civilization that builds a space infrastructure: the kind of space development that occurs will be a function of the kind of civilization that undertakes this development. But this is not merely an asymmetrical expression of a given kind of civilization that builds a given kind of space infrastructure; the buildout of a given kind of space architecture will have (or would have, in each case) consequences both intended and unintended, influencing in turn the civilization that builds the infrastructure.

For a terrestrial analogy, consider the buildout of transportation networks: Japan has a rail network that allows almost anyone to travel anywhere without the need of a personal vehicle; Europe has both extensive highway systems and extensive rail networks; the Americas have relied mostly on road networks and airports for transportation. Each of these transportation infrastructures is a reflection of the society that built the infrastructure, but the existence of the infrastructure in its turn contributes to the growth of certain social institutions while limiting the possibilities for other social institutions. Infrastructure projects are not socially neutral; they represent the buildout of a particular kind of society.

What kinds of societies, then, pursue particular kinds of space development? During the Cold War, space development took the form of the Space Race, which was an ideological competition intended to prove one social model superior to the other. But the Cold War eventually converged on the Apollo-Soyuz handshake in space. That cooperation, over several decades, grew into the ISS, and many see this cooperative model as the future of space development, even as private industry enters the launch market and national space programs multiply. What do these divergent trends portend for the future of space development? Let us turn to some futurist scenarios for relatively near-term prognostications in regard to the forms that social and space development may take.

2. The Problems of Futurism

Many futurist scenarios are formulated without any reference whatsoever to space development. It is this kind of blindness to an opportunity that could grow into a future that dwarfs all other possible futures that makes futurism so consistently disappointing. [1] Past futurist efforts have not merely been wrong, but often in retrospect are laughable, so wide of the mark are they. Futurists have learned at least a few lessons from their past disappointments, now typically framing multiple scenarios based on explicitly identified variables, rather than predicting particular events or developments.

Recently there has been much discussion of a 2010 Rockefeller Foundation study, Scenarios for the Future of Technology and International Development, because one of the scenarios of the study (“Lock Step”) so closely resembled the events of 2020, but the interesting feature of the Rockefeller Institute study was its creative use of a graphed quadrant defined by two variables (also known as a political compass), with the variables being political and economic alignment on the one hand, and adaptive capacity on the other. [2] If one takes these two variables as continua and uses the continua as x and y axes of a graph, the four quadrants of the graph define four scenarios, as follows:

1. “Clever Together” (strong alignment, strong adaptive capacity)

2. “Lock Step” (strong alignment, weak adaptive capacity) [3]

3. “Smart Scramble” (weak alignment, strong adaptive capacity)

4. “Hack Attack” (weak alignment, weak adaptive capacity) [4]

What this principled futurism with scenarios defined by variables implies is that, if our world today more resembles the “Lock Step” scenario than the other scenarios defined by the method employed, that is because the world is becoming more aligned but with less adaptive capacity. The fact that a futurist scenario written ten years ago bears some resemblance to the world today is a tribute to the well-chosen axes of the Rockefeller Foundation futurists. [5]

Another principled futurist schematism is that of the Tellus Institute, which instead of employing a compass framework (four quadrants divided by two axes), distinguishes between scenarios that are better (“Great Transitions”), approximately the same (“Conventional Worlds”), or obviously worse (“barbarization”) than the world today. Then for each of these three possibilities, two further permutations (better and worse) of each possibility are defined, for six possible scenarios:

1. Market Forces (a conventional world in which market-driven forces dominate)

2. Policy Reform (a conventional world in which significant reforms are possible)

3. Fortress World (barbarization unto a neo-feudal society) [6]

4. Breakdown (barbarization unto civilizational collapse)

5. Eco-communalism (a great transition to local, ecologically sustainable societies)

6. New Paradigm (a great transition attended by a variety of glittering generalities, aiming at, “…a just, fulfilling, and sustainable civilization”)

While I find the futurism of the Rockefeller Foundation and the Tellus Institute to be interesting and instructive, I also find them to be fatally flawed, and not merely because little or no hint of space development plays a role in their scenarios. The Tellus Institute, for example, cannot let go of the idée fixe of world government (I wrote about this recently in When Futurism Gets Stuck in the Past), and therefore defines its scenarios such that a closer approximation to world government is always preferable, while the maintenance of local governments is always suboptimal. Similarly embedded presuppositions vitiate the value of the Rockefeller Foundation report.

John Maynard Keynes in his seminal work The General Theory of Employment, Interest and Money, wrote: “Practical men, who believe themselves to be quite exempt from any intellectual influence, are usually the slaves of some defunct economist. Madmen in authority, who hear voices in the air, are distilling their frenzy from some academic scribbler of a few years back. I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas.” [7] Keynes was right, but these influences are not confined to practical men. Dreamers and utopians are guilty of the same fault, as we see throughout futurist writings; embedded presuppositions, rarely made explicit, guide most futurist scenarios. In order to transcend our presuppositions and fundamentally question our relationship to the future, we need to take the presuppositions themselves as variables that may play out to a greater or a lesser extent. It is only through questioning our assumptions that we can ultimately understand ourselves and understand where we are going.

There are any number of institutional futurist scenarios, different to some degree from the reports of the Rockefeller Foundation and the Tellus Institute, as there are any number of institutions that produce them. [8] For example, ARUP (a consultancy that assists in the construction of major infrastructure projects) has produced a report, 2050 Scenarios, that, like the Rockefeller Foundation, details four future scenarios, and, also like the Rockefeller report, employs a compass, with its x-axis a continuum from social deterioration to social improvement, and with the y-axis a continuum from biosphere deterioration to biosphere improvement, defining its four scenarios as follows:

1. “Post Anthropocene” (social improvement, biosphere improvement)

2. “Humans Inc.” (social improvement, biosphere deterioration)

3. “Greentocracy” (social deterioration, biosphere improvement)

4. “Extinction Express” (social deterioration, social deterioration)

The ARUP reports notes, “The science-based targets of the nine Planetary Boundaries, Arup’s Drivers of Change cards, as well as the United Nations’ Sustainable Development Goals (often abbreviated as UN SDGs) were used to set parameters and guide the scenario development.”[9] The charts that accompany each scenario imply that the report writers relied heavily upon UN SDGs, which in the most optimistic scenario, “Post Anthropocene,” are all shown as “improved” [10] over today, while the most pessimistic scenario, “Extinction Express,” the UN SDGs are shown as all deteriorated, while the “Greentocracy” and “Humans, Inc.” scenarios are mixed in terms of progress or deterioration of UN SDGs.

Space development is mentioned in the ARUP report in the context of the most pessimistic of the scenarios: “The depletion of Earth’s natural resources has necessitated the expansion of new extractive frontiers in space and the deep sea” (p. 60), as though they were seeking a pretext to frame space development in the worst possible light. Global Trends 2030: Alternative Worlds (2012) by the National Intelligence Council includes a smattering of references to space development, frequently in conjunction with the militarization of space. For example: “The ability of a future adversary to deny or mitigate that information advantage—including through widening the combat to outer space—would have a dramatic impact on the future conduct of war.” (p. 69) The book Journey to Earthland: The Great Transition to Planetary Civilization (2016) by Paul Raskin of the Tellus Institute, briefly mentions space development (pp. 78, 85, 92), although in a better light, a more utopian light, than ARUP or the NIC. Scenarios for the Future of Technology and International Development (2010) from the Rockefeller Foundation has no mention of space development at all. In none of these reports is space development integral across all scenarios, and in none of the scenarios does space development play a significant role in the development of civilization. [11] Rand, to their credit, engages with the idea of space exploration to a much greater extent. [12]

For what little is said of space development in institutionalized futurism, the space development architectures are characterized in terms of resource extraction and military development. These motivations could drive space development futures based on resource extraction and military supremacy imperatives, which would entail distinctive space infrastructure architectures in each case. In other words, we can already see in these scenarios qualitatively distinct forms of space development, even where space development is not seen as central to a future scenario.

3. Beyond Institutionalized Futurism

The futurism discussed in the previous section I will call “institutionalized futurism,” as all of these reports were overseen by institutions and were written by teams of authors who work within the institution in question. Since institutions are created for a purpose, we rightly expect that purpose to be expressed throughout an institution, including being expressed in the reports of an institutional think tank. This is quite clearly the case with the reports described above, which come from institutions with agendas ranging from the conventional status quo to utopianism.

All of the scenarios that we have examined from institutional futurism have in common assumptions regarding shared values across nation-states, populations, and geographical regions. [13] In the Rockefeller Foundation report these assumptions are smuggled in as “alignment,” while in the ARUP report the burden is borne by improving societal conditions. However, it is meaningless to posit convergence or alignment of interests and values where these interests and values are left as a cipher, and that is why I say that these assumptions are “smuggled in.”

The Tellus Institute is the most egregious in its utopianism, that is to say, in its denial of the reality of the human condition, which is a condition of a plurality of interests and values, many of them misaligned, admitting of no common standard of social improvement. However, the utopianism of the Tellus Institute is a consequence of the Institute making its interests and values explicit, whereas in the Rockefeller and ARUP reports these interests and values are artfully dissembled—not exactly hidden, but also not displayed in the way that the Tellus Institute displays them. In this way, utopianism is a valuable exercise, as it makes explicit what others are thinking but do not say aloud. There is a sense in which the Rockefeller and ARUP reports exemplify what the Tellus Institute calls “Conventional Worlds,” as these reports embody unstated assumptions of Enlightenment ideology as it is understood in the early twenty-first century. The Tellus Institute, by contrast, plainly states these assumptions, and this explicitness is a virtue.

As a contrast to the institutionalized futurism considered above, let us now consider some instances of individual futurism. Individuals, it is true, are more vulnerable to simple mistakes (in a group, these would be pointed out) and to personal quirks and partiality (which would be diluted in institutionalized futurism), but they are not beholden to an institutional culture, and they are less vulnerable to groupthink that a number of individuals gathered together under an institutional umbrella.

As we have seen, space development does not seem to greatly interest institutionalized futurism. If we expand our survey of futurism to include individual futurists, it is an easy matter to find individuals who focus on space development and little else. I am going to avoid these and other specialist scenarios in order to discuss futurist scenarios of more general interest. There are, of course, countless individual futurists, but I will only mention two.

Peter Thiel in a number of talks has lately emphasized three scenarios for Europe’s future, asserting that a scenario needs to be concrete in order for it to be meaningful. This concreteness requirement is interesting; we have seen in the reports of institutionalized futurism the use of fictionalized vignettes in order to try to make these scenarios concrete, although I think that these efforts are much less effective than Thiel’s plain-spoken alternatives. His three scenarios are 1) environmentalism, 2) the surveillance state, and 3) Islamization. Intimations of all three are already present in contemporary Europe, so that little imagination is required to extrapolate any one of these into the future in a concrete and realistic manner.

Peter Thiel’s insistence upon the concreteness of future visions of society is possibly a reaction against the glittering generalities of utopianism and tacitly introduced shared values in terms of alignment or improvement. Thiel focuses on the hopes of fears of ordinary persons living and working today in societies in which environmentalism, state surveillance, and the presence of Islamic minority enclaves are already a reality, and any one of these could become the determining reality of Europe’s future.

The other individual futurist I will mention is Laurence Smith, who wrote The World in 2050: Four Forces Shaping Civilization’s Northern Future (2010). He has focused on approximately the same time period as the Rockefeller Foundation, ARUP, and the National Intelligence Council. Smith narrows his focus by discussing the far north, but his scenarios have wider repercussions and so can be readily extrapolated to a planetary scale. While Smith’s book is longer than the institutionalized reports discussed above, he doesn’t go deeply into methodology, or employ a schematic approach as in the institutionalized reports, but, like Thiel, he develops trends existing in the present in order to converge upon a future that exemplifies the direction he sees these trends heading toward.

The four forces that Smith identifies are demography, growing demand for natural resources, globalization (which, as Smith characterizes it, resembles “alignment” in the Rockefeller Foundation report), and climate change. Whereas Thiel identified three forces in the present and implied their divergence, Smith identifies four forces and weaves them together, implying their convergence, but both approaches involve identifying trends in the present and extrapolating them into the future. Smith explicitly characterizes his futurism as a thought experiment, and seeks to inject a conservative bias into his thought experiment by obeying four ground rules: 1) no silver bullets (only incremental technological progress), 2) no WWIII (no reshuffling the geopolitical deck), 3) no black swan events (which he calls “hidden genies”), and 4) the slogan “the models are good enough” (meaning that conventional scientific predictions guide his scenarios). It is worth noting that Thiel did not mention any similar cautions, but his three scenarios are consistent with Smith’s ground rules.

Where futurism is formulated in terms of historical trends and social forces, rather than being laid out in the form of a political compass, the variables are the rapidity of the development and the completeness of its realization, and these correspond to the axes of compass futurism: any two trends or forces identified by Thiel or Smith could be used to construct four scenarios based on quadrants defined by two axes. Thus Thiel’s three scenarios of environmentalism, surveillance, and Islam for Europe can each admit of how rapidly the scenario comes into being and how completely the scenario is realized. For example, environmentalism as a political project might unfold according to some accelerated timeline tied to a deadline in the near future, [14] or more slowly over 50 years, 100 years, or 200 years. And the degree of realization of an environmentalist political project might be diluted by the admixture of other trends that are also realized over a similar time period.

4. Futurism at the Scale of Civilization

My futurism is going to be an instance of individual futurism, for obvious reasons, and like Thiel and Smith I will identify trends in the present to play out in the future, but unlike Thiel and Smith my interest is in futurism on the civilization level. Seeing the future through the lens of how civilizations develop, and even how new civilizations come into being, casts the enterprise in a new light, and accounts for some of my choices of scenarios.

To be fair, in the kind of futurism that only looks toward the next thirty years or so (as with the futurism I have considered so far) [15], change at the scale of civilization isn’t in the cards, and the varying continua that we find most significant are precisely those that could be found in any civilization of any kind, and which were the focus of the institutionalized futurism discussed earlier: more or less economic activity, more or less adaptive capacity, a better or worse environment, etc. However, while the most noticeable developments over this near-term horizon will be sub-civilizational, these variables will continue to vary and even to reverse themselves indefinitely into the future, while the most important developments—the developments that will continue to shape history over longer time horizons—will be those that occur on a civilizational scale. A distinction can be made, then, between what I will call zero-sum variables that will pass through cycles of improvement or deterioration (as defined by some index) [16] and directional variables that will push human history toward unprecedented developments; civilizational scale variables are directional variables, and we will focus on these. [17]

How future developments manifest in institutions will be in part a function of the structure of the institutions in question. I define the institutional structure of civilization as an economic framework coupled to a conceptual framework by a central project. What is a central project? When a sufficiently large number of persons are able to unify their efforts around common interests, meanings, and values, I call this the central project of a civilization, but in so doing I recognize that conditions that allow for common interests and values are always limited in space and time. Civilizations rise and fall as conditions allow for large-scale social organization to unify around coherent social purposes. Such purposes are re-interpreted over time and so constitute a moving target; eventually conditions are transformed to the point that the purpose (or the social body devoted to the purpose) can no longer remain coherent, and the social institutions that had temporarily formed about the purpose begin their dissolution. Civilizations may, at this point, bifurcate [18], transform [19], or cede their place in history to a successor [20].

If you will grant me my institutional analysis at least hypothetically (having a model at least gives us a common framework for discussion), the most important question about a civilization, and perhaps the most difficult question to answer for the most complex and longest enduring civilizations, is what constitutes that civilization’s central project. For any new civilization that should arise in the future, the most significant question is what its central project will be, as this will be the glue that will hold the civilization together, that will mediate between practices that keep the civilization functioning and the theories by which a civilization justifies itself to itself, explaining the world in a way that will make sense for the civilization’s population (and for its neighbors, with which it will be engaged in relationships of cooperation, competition, and conflict).

Building on this institutional analysis of civilization, I will frame my futurist scenarios on a civilizational scale, and in terms of the nascent central projects of future civilizations coming into being. The only kinds of civilization that can come into being in the future are those that are consistent with having our civilization as their past, thus I see futurist scenarios through the lens of the kind of civilization we have today, and the kinds of civilization that ours could become, depending upon the trajectory of development we pursue. Therefore I will formulate my scenarios in terms of the kind of future civilization that comes into being as the result of a particular ideology assuming the role of central project.

Moreover, I will adopt most futurists’ indifference to space development by postulating future civilizations that constitute what I have called indifferently spacefaring civilizations, which is a civilization that does not take spacefaring as its central project. So we will consider futurist scenarios like those formulated by futurists, whether institutions or individuals, in which space development and space exploration do not play a central role in civilization, but may still be technically and economically possible for the civilization in question. In these scenarios, space development will not occur as an end in itself, but, if it occurs, it will occur as a means to the end or ends embodied in the central project. Indifferently spacefaring civilizations in the future will have to have some central project as the purpose that drives human activity, and without which social cohesion fails and a society fragments, but in what follows that central project will not be spacefaring.

5. Six Possible Civilizations

I have my own futurist scenarios of which I am rather fond, and these scenarios grow out of contemporary trends and forces, much as we find in Smith and Thiel, rather than deriving from a schematic framework, like the institutionalized futurism we have considered. However, the futurist scenarios I have previously worked out were not based on my current understanding of civilization, which will be my point of departure here. Focusing on kinds of civilization, and differentiating kinds of civilization by differentiating central projects of civilization (which is to say, the macro-institutional structure of civilization remains the same in all instances of civilization, even as the central projects will differ), I will (briefly) discuss the following scenarios for civilization:

1. The Enlightenment — One could just as well call Enlightenment civilizations humanist civilizations, as this communicates much of the content of the Enlightenment. I maintain that, since the Enlightenment, western civilization has attempted to make the Enlightenment the central project of civilization. In historical terms, the Enlightenment is still inchoate and not yet fully formed (like Christianity in the third century AD), and in so far as we today constitute an Enlightenment civilization, we have great difficulty in seeing this for what it is. There is a sense in which future Enlightenment civilizations are scenarios of stagnation, as the ongoing Enlightenment project means more of the same, but with variations within the parameters defined by Enlightenment imperatives.

2. Science — I have discussed the possibility of a properly scientific civilization, i.e., a civilization that takes science as its central project, in several places, especially Properly Scientific Civilization and The Central Project of Properly Scientific Civilizations. Civilization today is indifferently scientific, meaning that science plays an important role in Enlightenment civilization, but only serves as an end in itself for particular individuals and institutions, and not for society on the whole. A society devoted to the growth of scientific knowledge as an end in itself would undertake scientific research not because it improves human life or because it produces new technologies and industries, but simply for the sake of scientific knowledge.

3. Environmentalism — I have often said that environmentalism is the only ideology to emerge in the second half of the twentieth century with the power to influence the policy of nation-states, and even to make or unmake political destinies. Thiel recognized this in proposing environmentalism as one of the concrete futures for Europe. We can already see several possibilities for environmentalism as a nascent central project, including quasi-religious intensity of belief.

4. Traditionalism — Taking Julius Evola as my point of reference for traditionalism, I will identify traditionalism as an attempt to return to pre-modern (i.e., pre-Enlightenment) principles of social organization, though not necessarily a return to (specific) pre-modern institutions. A contemporary traditionalism sufficiently adapted to the transformative influence of industry and technology might not be recognizable as traditionalism from the perspective of past institutions, but that isn’t the point. Science came of age under absolutist regimes, and there is no reason to believe that science and technology cannot continue to develop under a future traditionalist absolutism.

5. Virtualization — The class of civilizations considered under “virtualization” will be all those that take computation and virtual worlds as their central project, which includes singularity scenarios, human enhancement (transhumanism), and John Smart’s Transcension Hypothesis, inter alia. I have previously written about scenarios like this in A Virtually Optimized World and Existential Risks to a Virtually Optimized World. As the cultivation of virtual worlds could potentially substitute for outward exploration and expansion, virtualization scenarios are mostly inwardly focused (not unlike the Enlightenment, or humanist scenarios), with a proportionately diminished interest in the outward focus of spacefaring.

6. Urbanism — In so far as civilization began with the building of cities, civilization is an essentially urban undertaking, so that to take cities as the focus of civilization is to make civilization itself its own reflexive central project. And indeed reflexivity often characterizes the later stages of social development (an inwardness not unlike virtualization scenarios). In the urbanism scenario, human beings focus on better ways of living together in cities, and the world more and more approximates an archipelago of megacities in which almost all human beings live, and so have a compelling interest to optimize urban life, which could well result in taking the cultivation of urban life as an end in itself.

Needless to say, all of these scenarios admit of countless interpretations, so that we are here only generically discussing these ideas [21]; each scenario above is rather a class of scenarios exemplifying a range of zero-sum variables in constituent institutions. Also, the above list is not intended to be exhaustive; we cannot rule out the possibility of a dark horse central project. The most interesting and most likely scenarios for the future of civilization will be those that incrementally depart from the above generic scenarios, and continue to developmentally diverge until they become something unrecognizable and inconceivable from our present perspective. [22] Thus we take up these scenarios in the spirit of experimentation and exploration.

Following Laurence Smith, I will note some ground rules for the scenarios. In every futurist scenario we can formulate, there is a permutation of that scenario in which space development comes to be neglected and ceases to play any role in human history for the foreseeable future. However, a certain amount of space development is already “baked into the cake,” as it were, by plans and budgets already in existence today. This planned and funded space development will go forward, but whether it will be a starting point for greater things, or whether it will be allowed to die, as the Apollo program was defunded and abandoned, will be integral with ongoing developments, which are subject to change.

In the sense of multiple distinct scenarios that converge upon space development neglect, contemporary space development is a race against time to establish an independent and self-sustaining human presence in space before history forecloses on this opportunity and humanity remains confined at the bottom of its homeworld gravity well until extinction. Each scenario in its space development neglect permutation is a unique race against time scenario, in which the race is conducted under distinct circumstances that bear upon its success or failure.

Just as every scenario we will consider will have a permutation in which space development comes to be neglected, every scenario we consider will also have a permutation in which that civilization is a failing civilization that is on a trajectory to extinction (i.e., a civilization for which a failure condition obtains). In the case of civilizational failure, space development for that civilization must necessarily end (even if spacefaring has an integral role in such a civilization), so there is a sense in which we can say that every scenario we will consider has at least two paths to the end of space development: through the neglect of space development, and through the failure of a civilization that might otherwise superintend space development of its own peculiar kind.

However, each futurist scenario also suggests a permutation in which space development plays a role in the political, economic, social, and scientific development of future society, even if that role is distinct from the role that space development plays in the contemporary world, or would play in a properly spacefaring civilization that takes spacefaring as its central project. I will focus on these latter permutations, though it might well be interesting to consider the many distinct scenarios by which space development might fail under different civilizational scenarios.

Above all, the purpose here is not merely to enumerate several quantitatively distinct space development futures (i.e., more or less space development), but more so qualitatively distinct space development futures (i.e., different kinds of space development). Space development admits of the possibility of more or less rapid deployment (rapidity of realization), and or more or less complete deployment (degree of realization), but both of these variables apply to all space development futures, and so constitute what I earlier called zero-sum variables.

“Religion is… the first spring of civilization: it preaches to us, and constantly reminds us of brotherhood, softens our heart, elevates our spirit, flatters and directs our imagination by extending the field of rewards and advantages into boundless territory, and interests us in the fortunes of others like us, while we envy this almost everywhere else.” Victor de Riqueti, marquis de Mirabeau [23]

5a. Space Development of Enlightenment Civilizations

I begin with the assumption that the Enlightenment project is the central project of western civilization in its present incarnation, and that the Enlightenment project has passed through multiple permutations since its inception. I will not attempt to make the argument for this sweeping claim here, as this requires its own exposition in a separate place. The assumption bears upon the present discussion because postulating the Enlightenment project as the central project of an indifferently spacefaring civilization means that our present civilization seamlessly develops into a spacefaring civilization while retaining its central project intact, albeit changed, as the Enlightenment project continues to take shape in light of ongoing contingent factors that influence its interpretation in theory and its application in practice. In a sense, then, an Enlightenment central project is the baseline scenario that represents the most probable future development for contemporary civilization, because it is a continuation of the same ideological program as the previous 250 years or so. Should the interpretation of the Enlightenment become fixed and cease to change, no longer passing through novel permutations, the future scenario of Enlightenment civilization would be a scenario of stagnation.

One way to conceptualize the Enlightenment project as a central project of civilization is its interest, varyingly expressed, in human flourishing. [24] As noted above (at 5.1), the Enlightenment largely coincides with humanism, which could be defined in terms of human flourishing, and even among the polarized political differences that have appeared in the wake of the Enlightenment—most notably the left/right political dichotomy—human flourishing is represented on both sides of the ideological divide, albeit differently interpreted. Is human flourishing as realized within human societies, best secured by liberty or by equality? Can liberty and equality be reconciled within a single social context?

An Enlightenment civilization’s space infrastructure development could be characterized as humanism in outer space. Where human flourishing is an end in itself, and spacefaring, among other activities, is a means to the end of human flourishing, space development serves the end of human development and is pursued as it is understood to realize the ends of human development. Yet the same conflict that has dogged the Enlightenment since its inception would continue to play out in competing visions of space development: would human flourishing in space best be secured by the liberty of space development (nascent private space industries vying for profit and market share) or would human flourishing in space best be secured by the equality of space development (an international space program in theory open and accessible to all)?

Human development is one of the great themes of the Enlightenment, especially human development in the form of education, as in Rousseau’s novel Emile. A minimalist Enlightenment space development scenario would involve an emphasis upon educational initiatives, which could include a significant component of space science, but only where space science does not conflict with Enlightenment ideology. Such a space program framed in terms of an educational initiative could involve a continued presence in space like the ISS, perhaps small scientific bases on the moon and Mars, and more space science undertaken by robotic probes.

While the space science component of space development as an educational initiative points toward automated spacecraft as scientific instruments, the deeper humanist promptings of the Enlightenment point toward a human space program in order to realize human possibilities in space, though the funding for such initiatives would always be balanced against humanist initiatives undertaken on Earth for the majority of the population largely untouched by and uninterested in space development. Thus a human space program would be pursued, but would be subject to both the opportunities and the conflicts of Enlightenment ideology.

In both of these scenarios—the space science educational scenario and the human space program scenario—any scientific knowledge derived as a consequence would be a mere means to the end of human flourishing. Neither science nor space program nor national achievement would take precedence over human achievement, which, like the tension between liberty and equality, is subject to a tension between individual human achievement (which represents liberty) and collective human achievement (which represents equality). If an Enlightenment civilization engaged in space exploration and settlement can balance these opposing imperatives (as Enlightenment civilization has, to date, attempted to do, though not always happily), it could extend itself into the cosmos; but if it fails to negotiate a sustainable social model suspended between polarized extremes, its efforts will fracture, and, from the fracturing of Enlightenment civilization, other civilizations will emerge in its wake—smaller, and so less capable, but also more focused and less constrained.

“The catastrophes provoked by the wars and revolutions of the past concerned or wrought havoc upon only limited regions; in the future a political catastrophe would mean the self-destruction of civilization, perhaps of the whole of humanity.” Werner Heisenberg

5b. Space Development of Scientific Civilizations

The idea of a properly scientific civilization holds a great fascination for me, partly because it seems so familiar on the one hand, while on the other hand it would be something unprecedented, and, in its pure form, something utterly alien to us. It seems familiar because many scientists and philosophers have spoken as though we today live in a scientific civilization (I have discussed some of these claims in Pathways into the Deep Future and The Role of Science in Enlightenment Universalism); it seems unfamiliar when we stop to think about what would be entailed by human beings pursuing science as an end in itself and not as a means to an end, and to do so at the scale of civilization, and this could take us quite far afield.

The scientific revolution is often conflated with the Enlightenment project, and the two forces have been tightly intertwined in western history ever since both were present (meaning that Enlightenment civilization and scientific civilization could easily be mistaken for one another), but modern science is older than the Enlightenment and is distinct from it. That is to say, we could ideally isolate modern science from the Enlightenment, and vice versa, treating each separately, but that ideal isolation would be an abstraction, because the two are not separate in fact. Further developments in civilization could nevertheless separate the two, with a bifurcation of western civilization into a properly Enlightenment civilization and a properly scientific civilization.

Many scientists in the twentieth century came to understand the dark underbelly of science—Oppenheimer said that physicists had “known sin” as a result of having constructed nuclear weapons—that high technology made possible by advanced science was morally neutral, and could be exploited equally effectively for good or evil. That science is tainted with sin is a deeply Christian conception (by derivation), while the idea that scientists should be socially responsible (i.e., responsive to the impact of their work upon society) is an Enlightenment idea, so we see the degree to which existing conceptions are an admixture drawn from a long history. However, there are also deep sources in the western tradition that identify knowledge as the good; this was the position of Socrates and Plato (along with the corollary that no man sins knowingly), and these would be the sources to which a properly scientific civilization would return in order to justify the pursuit of knowledge as an end in itself.

For a properly scientific civilization, space development would be about scientific research, and outer space offers almost limitless possibilities for research. Science as we know it today, as it has been developed on Earth, is a mere fragment of what science can be, what science can become, in a cosmological context. Science pursued as an end in itself could not avoid this realization, and as a result would be driven to extensive exploration and discovery in the cosmos, as has occurred in past episodes of scientific curiosity.

There is a sense in which the European Age of Discovery was a practical reflection of the theoretical implementation of science. As I like to point out, the scientific revolution occurred before the Enlightenment and before the industrial revolution, so we have the historical example of science as practised before the advent of these features of modernity. The scientific revolution and the Age of Discovery were respectively the framework and the infrastructure of a properly scientific civilization that was on the verge of realization, but which was preempted by the Enlightenment and industrialization (more on this terminology in sections 7 and 8 below).

The imperatives of a properly scientific civilization would not resolve the tension between those who would prefer to spend the entire space exploration budget on automated probes and those who would include a human space program as part of space exploration. As in other civilization scenarios developed here, even under the umbrella of a properly scientific civilization, many different degrees of space development buildout are possible. However, a maximally robotic space science program would still likely involve human scientists in space, perhaps not at the scale of settlement and the establishment of permanent communities, but still a robust human space program, perhaps at the scale of, say, Antarctic scientific missions, where thousands stay in settlements in Antarctica primarily conceived and operated as research stations. Needless to say, a maximally human space science program would always continue to use robotic space science missions as an extension of human reach, to go ahead of human researchers and to go into environments where human beings could not go, like the surface of Venus.

“The question is whether any civilization can wage relentless war on life without destroying itself, and without losing the right to be called civilized.” Rachel Carson

5c. Space Development of Environmentalist Civilizations

Environmentalism is the only ideology to emerge in the second half of the twentieth century that has proved to have transformative ambitions and social and political reach. Environmentalism has not only inspired changed practices (shaping the economic infrastructure), but has also produced a significant body of scholarship—in the case of conservation biology, this scholarship is scientific, but environmentalism has also resulted in a distinctive environmental philosophy (shaping the conceptual framework). With this distinctively environmentalist theoria and praxis, an environmental central project is almost inevitable as the fulfillment of environmentalist thought. Whether or not an environmentalist central project would prove to be a viable form of human civilization is another matter; I will here assume that this is possible.

Environmentalism spans the spectrum of Enlightenment political engagement. Whether we are talking about the some kind of utopian eco-communalism (as in one of the Tellus Institute’s scenarios) or a dystopian ecofascism (as in ARUP’s “Greentocracy” scenario), merely identifying an environmentalist civilization based on an environmentalist central project does little to constrain the political institutions of such a civilization. Similarly, space development in an environmentalist civilization could span a spectrum from the minimal to the maximal.

While many environmentalists are personally skeptical of any space program, many credit the photographs made possible by the space program as inflection points in the development of environmental consciousness. The “Blue Marble” and “Earthrise” photographs in particular have been cited as playing a role in the rise of environmentalism to political prominence. This dual attitude to space exploration, both a distrust of its significance and a recognition of its value, suggests that environmentalist civilizations may bifurcate into those that are favorable to space development and those that are unfavorable to space development. These horns of the dilemma of space development under environmentalism point to radically different outcomes.

Humanity under an environmentalist civilization might entirely retreat from space, or might project itself into the cosmos in order to practice conservation on a cosmological scale, but, between these two radically different outcomes, the space development of an environmentalist civilization would first of all focus on Earth observation and maintenance of the terrestrial biosphere, maintaining and improving the satellite network we have for this at present. Research missions to other bodies in our solar system might be undertaken to determine whether or not any possessed some form of life.

The quest for life beyond Earth undertaken from an environmentalist perspective would likely mean an expanding definition of life based on unclassifiable phenomena likely to be found (i.e., unclassifiable from the perspective of terrestrial biology). This expansion of the conception of life would point to an expanding conception of conservation, which we have already seen on Earth with the extension of conservation efforts from particular species to biotic communities to the non-living context of biotic communities. The conservation worldview projected at cosmological scale may entail the conservation of entire worlds (such as Mars) even if no life is found, on the basis of the intrinsic value of that world’s features.

There would be, then, a dialectic in any environmentally-driven space program, in so far as the more space exploration is undertaken the more human beings will be made aware of diverse forms of emergent complexity that could be recognized as having intrinsic value and therefore are to be regarded from the perspective of conservation. The less space exploration undertaken, the less the conversation worldview is expanded, and the environmentalist perspective remains cosmologically parochial. Those sectors of society not entirely onboard with the environmentalist central project (for every civilization has its dissenting minority) would put pressure on wider society by forcing this dialectic to play out, expanding our conception of the universe at the same time as expanding space development. However, this dialectic of expansive vs. parochial conservation imperatives could play out as long as an environmentalist civilization could endure, unfolding over hundreds if not thousands of years, thus displacing significant space development into the distant future.

“…a civilization or a society is ‘traditional’ when it is ruled by principles that transcend what is merely human and individual…” Julius Evola

5d. Space Development of Traditionalist Civilizations

Traditionalism represents many forces acting in society, among them the rejection of the Enlightenment project in its many manifestations, meaning that traditionalism can have many manifestations as it counters the many manifestations of the Enlightenment. Traditionalism is not one, but many, as there are many traditions. The plurality of tradition extends not only to various traditions deemed worthy of preservation, but also to radically different conceptions of what it means to be a tradition. Usually when we think of traditionalism we think of the preservation of ancient (or, at least, old) traditions and institutions, preferably in their pristine and unaltered form—something like what Marx had in mind when he wrote that, “The tradition of all dead generations weighs like a nightmare on the brains of the living.” [25] But whatever tradition that traditionalism celebrates, I take the possibility of a traditionalist civilization to be the antithesis of the baseline Enlightenment scenario, and perhaps a reaction against it.

Perhaps the most eminent traditionalist of the twentieth century was Julius Evola, who explicitly rejected the familiar conception of traditionalism (conceived in terms of traditional institutions) in favor of a preservation of principles: “For the authentic revolutionary conservative, what really counts is to be faithful not to past forms and institutions, but rather to principles of which such forms and institutions have been particular expressions, adequate for a specific period of time and in a specific geographical area.” [26] Elsewhere in the same book Evola said of traditionalism: “…it is the form bestowed by forces from above upon the overall possibilities of a given cultural area and specific period, through super-individual and even antihistorical values and through elites that know how to derive an authority and natural prestige from such values.” [27]

Of course, there can be disagreement over the interpretation of the principles themselves to which Evola refers; I argued above that the more complex a civilization becomes, the more difficult it is to identify its central project. It would be all too easy to pluck out a few traditional principles and identify these as the authentic basis for a traditional society, while neglecting a number of principles no less present in past social formations. This problem is not insuperable, but it also cannot be taken lightly. However, my present interest is to assume that this can be done (as with the environmentalist scenario) and that a distinctive civilization can be based on consciously traditional motives.

A familiar caricature of traditionalism is its presumed rejection of science and rationalism (this is of a piece with the criticism of traditionalism of wanting to turn back the clock and return to the horse-and-buggy days), but science and rationality are among many ancient principles that contemporary peoples can choose to honor or not. It is Evola’s traditionalism of principles that is most readily adaptable to the science and technology that have developed since the industrial revolution; since modern science emerged in the midst of early modern absolutism, there is no reason that further development in science and technology could not occur in a revived absolutist tradition.

The space development of a traditionalist civilization would likely take the form of affirming the principles of a traditionalist society—honoring the past, affirming continuity with the past, seeking to live worthy lives and to pursue worthy achievements in the light of tradition, shunning novelties for the sake of novelty, and so forth. A traditionalist civilization might in this spirit pursue a “flags and footprints” space program intended to send the message of the superiority of the social system adopted by that civilization—proof of concept of the social model, as it were. An ongoing “flags and footprints” space program would not be a negligible accomplishment; in order to continue to establish historic firsts, ever more daring efforts would need to be made, and this would eventually mean the buildout of space development consistent with ever further missions into deep space.

If, as during the Cold War, a successful space program is intended to prove the merit of the social model that has facilitated that space program, one risk is that failure is then interpreted as a failure of the model, which is one of the sources of the idea that “failure is not an option.” One might then predict risk aversion, but in so far as risk aversion will produce neither heroic accomplishments nor heroic failures, risk aversion fails to serve the social model. A traditionalist society can embrace dead heroes, but it cannot do without heroism in the celebration of the established social order. A space program can supply heroes, and when events go badly, the heroes can be celebrated and their memory can be invoked to greater efforts in the future.

Moreover, it would be a relatively simple matter to frame the space frontier in terms of super-individual and antihistorical value; the naturally non-anthropocentric character of space places it beyond the human concerns defined by our geocentrism and planetary endemism. To travel into space is a concrete form of transcendence—it is to transcend the mundane world. There is a potential conflict here with the rootedness of traditionalism in a particular place and time, though this sense of rootedness could be used to great effect in the establishment of space settlements, in which the settlers develop an attachment to their new home and are prepared to bear any burden in order to make a success of it.

“It is more probable than not that, within the twentieth century, an ultraintelligent machine will be built and that it will be the last invention that man need make, since it will lead to an ‘intelligence explosion.’ This will transform society in an unimaginable way.” I. J. Good

5e. Space Development of Virtualist Civilizations

We have by now all become familiar with scenarios like the technological singularity, intelligence explosion, and a life lived in virtual worlds. The popularity of immersive gaming experiences has demonstrated the power of these possibilities. We do not yet know the limits of such scenarios, either the technological limits in terms of what is possible, or the human limits in terms of what human beings would be willing to sacrifice in order to live in a boundless virtual world. Virtualist scenarios could range from individuals maximizing their time in virtual reality to the complete abandonment of biology. The former case would leave much of civilization intact; the latter case would mean the end of human civilization, or a transition to para-civilization.

The boundless virtual worlds of a virtualist civilization could replace the actual experience of exploration and discovery, so that a virtualist civilization can expand virtually without expanding actually. Such a civilization could “grow” without leaving its homeworld, and may find the virtual worlds that it creates for itself to be more interesting and more satisfying than the actual world. However, a virtualist civilization would also be an energy-intensive civilization, both in terms of its need for ever-greater quantities of energy as well as its ever-increasing need to rid itself of waste heat.

Much that a virtualist civilization would want to do could be done more efficiently and at a larger scale in space. Space solar power would be an efficient and almost inexhaustible source of energy, and using this energy in space rather than on a planetary surface would mean that the waste heat could be radiated into space. Just as a virtualist civilization may have no interest in the outer world and so may invest no resources in space exploration and discovery, so too a virtualist civilization may have no interest in preserving the biosphere of its origin, if we assume that a virtualist civilization has naturalistic origins in some intelligent progenitor species evolving in a biosphere. The ability to radiate waste heat into outer space may be of no interest if a virtualist civilization is unconcerned about the condition of its homeworld biosphere. Indeed, a radically virtualist civilization might choose to sterilize its homeworld, strip away its atmosphere, and reduce itself exclusively to virtual existence. As I. J. Good observed, radical virtualization could “…transform society in an unimaginable way.” Even given this scenario, however, space solar power would still offer the advantage of being uninterrupted by diurnal cycles.

In the scenarios of Freeman Dyson, John Smart, and Clément Vidal, all of whom focus on high energy density civilizations (the Dyson sphere, Vidal’s Stellivore Hypothesis, and with Smart’s Transcension Hypothesis adding the element of turning inward to virtual worlds), there are to be found elements of the above scenario. All of these high energy density scenarios involve a considerable infrastructure buildout based on the civilization’s energy budget, so that even if we understand these civilizations to have turned “inward” to virtual worlds in place of outward exploration, all require a substantial infrastructure for their execution. Furthermore, the more radical the scenario (i.e., the greater the divergence from civilization as we know it) the more exotic and elaborate the infrastructure implied by the scenario.

In the virtualist scenario, the buildout of space development to serve a virtualist civilization could be a pathway to the emergence of other civilization only if a virtualist civilization remained a human civilization. If, as in the most exotic scenarios, human beings surrender their biological embodiment and pursue complete virtualization, the result is the end of civilization as we know it and the development of another kind of complexity, distinct from civilization even though descended from it. Space development could well continue, but it would not be the space development of human civilization, as humanity would have transformed itself into something wholly other than what we are as biological beings. But in so far as a virtualist civilization falls short of full virtualization, leaving at least part of the population as biological beings, a new human civilization could use a virtualized civilization as a stepping stone to other forms of civilization.

“The country is faced with an ineluctable task: that of adjusting what it builds to the realities of a machine-governed civilization…” Le Corbusier

5f. Space Development of Urbanist Civilizations

Civilization begins with cities [28], so that an urbanist civilization would constitute a reflexive return to origins for civilization—in a sense, a renewal, a re-founding, and a re-interpretation of what it means for human beings to live in cities: how we live in cities, why we live in cities, and what is the nature of cities as the domicile of human beings. Le Corbusier, a modernist’s modernist who rejected traditionalism on pragmatic, moral, and scientific grounds, famously said that a house is a machine for living in [29]; if we understand a city to be a place for human beings to collectively inhabit, then in the same spirit as Le Corbusier we can say that a city is a factory for living in. What Le Corbusier sometimes called “machinist civilization” was, for Le Corbusier, a call to rebuild cities on modern principles, even proposing to tear down a large portion of downtown Paris and build tower blocks, the Plan Voison.

Cities are many things. In so far as we understand the city as a unit of production, as a locus of economic opportunities, or as a ritual center for religious ordnances, we do not understand the city as an end in itself; it is a mere means to an end. But insofar as we understand the city as holding a special place in human affairs, where human beings have created a unique way of life, and therefore urbanism is to be cultivated as a central feature of human life, then the existence and flourishing of cities is an end in itself, and urbanism is the central project of a civilization that embodies this understanding.

A spacefaring urbanist civilization might see its spacefaring capacity as a way to extend and expand the urban project through building cities in many different environments, subject to many different selection pressures, and testing the possible limits of cities in every possible way, focused on the development of urbanism beyond Earth. In this way, spacefaring opens up possibilities that can allow an urbanist civilization to exhaust and thus to realize its potentiality; an urbanist civilization that remains on a single planet, on its homeworld, cannot fully realize its potential in the same way.
Cities in space and cities on other worlds would be a way to more fully realize the possibilities of urbanism.

However, space development undertaken on a sufficiently large scale would involve fundamental challenges to the urban paradigm. For example, it is not clear if or whether an artificial settlement in space would be a city, at least as we have known cities on Earth. This conceptual challenge to urbanism could be avoided by developing space settlements on the model of cities, following the urban paradigm as closely as possible in a racially different context, or by focusing on building cities on other planets or moons. Building cities on Mars would be entirely within the urban paradigm, and indeed it would be extraordinarily difficult for a homesteader on Mars to live apart from a large settlement, but artificial habitats in space would be a different matter.

If someone lives on an artificial settlement in space with 10,000 others, is this a city? Could human habitats be built that housed hundreds of thousands, or even millions, but which were not cities in the strict sense? What is the strict sense of a city? Do we even know the conceptual parameters of cities? What if one built such an artificial structure, and made it a “wilderness,” and placed all human housing and industry below decks, as it were? Imagine an enormous O’Neill habitat is constructed, with the inner surface given over to forests, meadows, trails, and gardens. There are a few cabins artfully distributed around the landscape. Almost everyone lives below decks in minimalist apartments, but everyone gets a week in a picturesque cabin several times per year. Also, no one is more than 5 minutes away from a walk in an apparently natural setting. There are natural amphitheaters and public parks that host daily events so that everyone has access to the “outdoors.” How would this compare to life in a contemporary city on Earth? Would this be a city? This example suggests that it may be possible to radically question our definitions and typologies of cities by presenting us with something unprecedented in previous human history.

The space development of an urbanist civilization could conceivably involve robust space development of cities across the solar system, including communities that would transcend the urban paradigm and point to another kind of civilization beyond the urbanist, being ripe for exaptation as a properly spacefaring civilization.

6. Internal Conflict, Growth, and Destabilization

In each of these scenarios we can discern a fundamental source of tension. For Enlightenment civilization, the tension is between freedom and equality, both of which are presented as absolute goods, and neither of which can be exhaustively reconciled with the other; for scientific civilization, it is between science and pseudo-science, which can also be seen as the tension between the appearance and reality of scientific knowledge, which, for fallible human beings cannot be dissembled; for environmentalist civilization, between humanity negatively impacting the biosphere and humanity as an agent facilitating environmental imperatives (i.e., between humanism and anti-humanism); for traditionalism, between the preservation of particular institutions and the preservation of principles; for virtualization, between remaining human and surrendering humanity to full virtualization; and for urbanism, between the pull exercised by cities and the parallel desire to escape them, i.e., the dialectic of solitude and society.

Every civilization has internal conflicts; the triumph of a single central project in dominating a civilization does not mean uniformity of belief, but rather uniformity of presuppositions and a diversity of interpretations of the shared central project. We are all familiar today with the internal conflict of the Enlightenment, which, since the French Revolution, has taken the form of the political left vs. the political right. Past civilizations had their internal conflicts as well. For us today the Investiture Controversy is almost meaningless, as few are kept awake at night over the problem of secular appointment of bishops, and we do not see the political implications of differing interpretations of the Beatific Vision, but these were some of the conflicts that struck at the core of medieval European civilization. Similarly, future civilizations will have their internal conflicts. Both parties to these conflicts will share their dedication to the central project, which is a presupposition of their thought and action, but will disagree on its interpretation and the best means to its end.

When a civilization is at the height of its powers and confidence, internal tensions are channeled toward creative ends, so that the dialectic of opposed interests pushes the social narrative forward. When a civilization is failing, at a low ebb of confidence and much of the population feeling little or no sense of investment in the central project, then internal tensions can become destructive, opening a rift within that civilization, through which chaos pours out, like fuel poured on a fire, destabilizing the social whole. It is not that the tensions are different when they become destructive, but that the ability to manage and to employ the consequences of social tension toward constructive ends has faltered and destabilization escalates.

Joseph Schumpeter characterized capitalism in terms of “creative destruction,” and anyone who has lived long enough has seen both the constructive and the destructive side of capitalism; ideologues see only one side or the other, and not both. It is the same with the tensions intrinsic to any central project. To take only one of my scenarios as an example, I noted that the tension within environmentalism is between humanism and anti-humanism. Humanism is constructive when it brings out the best in us, our idealism and our altruism, and destructive when it becomes hubristic pride; analogously, anti-humanism is constructive when it is manifested as the pursuit of non-anthropocentric understanding, and destructive when it is manifested as self-loathing misanthropy. Constructive humanism and constructive anti-humanism can be channeled together into larger projects; destructive humanism and destructive anti-humanism can only conflict with each other, and withdrawal becomes the only rational strategy, further weakening the social whole.

Internal conflicts will push zero-sum variables back and forth, oscillating above and below an equilibrium value, which explains why within a given civilization these variables do not become directional variables and push civilization in a given direction. The imperatives incorporated in a civilization’s central project determine what are zero-sum variables and what are directional variables; in another civilization, the same forces shaping history could be differently distributed among zero-sum variables and directional variables.

Any of the internal conflicts in the civilization scenarios discussed above could be graphed as two axes defining four quadrants, as in the institutional futurism examined in section 2, yielding multiple scenarios all consistent with one and the same institutional structure of a given civilization. A long-lived civilization in passing through permutations of its central project may play out all of these possibilities, by turns exemplifying superficially distinct stages that are all expressions of the same underlying central project.

7. Buildout and the Exaptation of Civilizations

What can be learned from this exploration of six scenarios of space development futurism? I have argued that the most significant developments—those of the greatest impact that will endure for the longest period of time—are those tied to the destinies of entire civilizations (the directional variables of a civilization). As civilizations are born, mature, flourish, decay, and die they realize purposes, meanings, and values embodied in the central project. The buildout of infrastructure and framework is part of this realization of purposes, meanings, and values. [30]

In the same way that the buildout of infrastructure is an expression of a society that influences the development of that society in turn, the buildout of our conceptions of the future is an expression of the society that develops this conceptual framework, and the conceptual framework, once formulated, becomes the framework within which we express ourselves, our hopes, our desires, our fears, and our aspirations, just as the buildout of infrastructure becomes the setting within which the events of the future will transpire.

As noted earlier, infrastructure is not socially neutral; it embodies, albeit implicitly, a particular structure of society and a particular worldview. The same will be true for spacefaring infrastructure, which will correspond to the civilization that builds the infrastructure. Allow me to summarize in the following theses how the institutional structure of civilization is shaped by buildout:

The Infrastructure Thesis:

A civilization fulfills only those possibilities for which an infrastructure buildout has been undertaken (whether knowingly or unknowingly) that can realize the possibilities in question.

A civilization has the possibility of realizing potential transformations of itself, perhaps many different transformations into novel forms of civilization, but only those possibilities that it acts upon through buildout are ever realized. In the specific case of transformation into spacefaring civilization, the Infrastructure Thesis becomes the following:

Spacefaring Infrastructure Thesis

Spacefaring breakout for any civilization whatsoever will occur only after a spacefaring infrastructure buildout makes the breakout possible.

Space development has both an infrastructure dimension and a framework dimension; infrastructure does not exist in a vacuum, and it is not constructed in a vacuum. In each of the scenarios discussed above, a particular conception of how space ought to be developed (the framework) entails an infrastructure buildout, though this buildout in turn is subject to exaptation. Thus the Infrastructure Thesis alone is incomplete, and must be supplemented with a complementary formulation regarding the framework:

The Framework Thesis

There is no infrastructure buildout without a framework buildout that confers meaning and value on the effort, motivating and justifying the infrastructure buildout.

In the specific case of spacefaring civilization, the Framework Thesis becomes the following:

Spacefaring Framework Thesis

Spacefaring breakout will occur after a conceptual framework is formulated that is adequate to motivate the construction of a space-capable infrastructure at a scale consistent with breakout.

Both Infrastructure Thesis and Framework Thesis invoke the concept of the buildout of the institutional structure of civilization, which can for formulated as its own thesis:

The Buildout Thesis

A civilization makes those transitions that its institutional buildout makes possible.

Again, for the specific case of spacefaring civilization the Buildout Thesis becomes the following:

Spacefaring Buildout Thesis

A space-capable civilization makes the transition to a spacefaring civilization through an institutional buildout that facilitates spacefaring.

A stagnant civilization that maintains itself only, devoting no resources to expansion, may be more viable in the long term than a growing civilization engaged in the buildout of infrastructure and framework. To commit resources to an infrastructure project involves an opportunity cost in terms of the alternative projects that are not constructed, and there is the possibility that a civilization might invest resources into building out infrastructure and framework that is a dead end, and, if this investment in a dead end comes at the opportunity cost of the buildout of viable scenarios for the future of that civilization (or its successor), buildout can be a way for a civilization to dig its own grave.

It sometimes happens in history that a civilization apparently confident in its purposes and possessed of energy and resources will exhaust itself building out infrastructure and framework, only to collapse from the effort (which we could call the Overshoot Thesis), and to have its buildout exapted by a new civilization that takes the place of the old civilization. We see this pattern in the economic growth of the Mughal Empire, which produced such masterpieces as the Taj Mahal and the Shalamar Gardens, and then ceded its control of India to the British. Both of these civilizations—Mughal India and British India—presided over a submerged Hindu civilization. Another example: the expansion of Hellenism under Alexander the Great involved the founding of Greek cities across West and Central Asia, but Alexander’s unprecedented conquests fell apart after his death, though many of the cities survived, some as part of the eastern Roman Empire (later Byzantium) and some as part of the Buddhist civilization of Central Asia, the result of idea diffusion along the Silk Road (which had left as its major artifacts the Bamiyan Buddhas that were destroyed by the Taliban), which endured until Central Asia fell to Islam.

The use of institutions built by a previous civilization to realize novel ends that come to be identified with a new civilization (this new civilization being a transformation facilitated by buildout) is a process of exaptation that is embodied in the Buildout Thesis. What is exaptation? The Cambridge Dictionary of Human Biology and Evolution has a brief entry on exaptation, but also refers the reader to “preadaptation,” which is defined as follows:

preadaptation: any previously existing gene, anatomical structure, physiological process, or behavior pattern that makes new forms of evolutionary adaptation more likely. Any trait that confers an eventual advantage before the conditions that will make it adaptive prevail…

Exaptation as I use the term is the social equivalent of biological preadaptation: when a new civilization comes into being, the society was preadapted for the transition. [31] While we can entertain future scenarios for civilization that are possible in principle, without an institutional buildout there is nothing to be exapted for novel initiatives and aspirations.

Since I have formulated an Infrastructure Thesis and a Framework Thesis, for purposes of completeness I ought to also formulate the implied Central Project Thesis, which is as follows:

Central Project Thesis

A central project is the axis of alignment for a civilization, integrating infrastructure and framework into a coherent whole with historical directionality.

In the present essay I have been exclusively concerned with civilizations that do not have spacefaring as an integral part of their central project (i.e., indifferently spacefaring civilization), but for purposes of completeness here is the spacefaring permutation of the Central Project Thesis:

Spacefaring Central Project Thesis

A spacefaring central project would be the axis of alignment for a spacefaring civilization, integrating infrastructure and framework into a coherent whole with historical directionality. [32]

If the above theses are a reasonable approximation of how civilizations function, then I can conclude that, if any of the above scenarios for civilization are realized, such civilizations will be the result of the exaptation of some existing buildout of infrastructure or framework that facilitates the emergence of such a civilization. In so far as there are already intimations of all my above scenarios in contemporary civilization, we can discern these civilizations in a nascent form. For example, there is already a significant buildout of urban infrastructure, and, in the form of urban studies, there is a growing buildout of an urbanism framework, so that intimations of an urbanist civilization already exist—there is a kind of nascent urbanist civilization, but whether this nascent civilization ever fully takes shape and consolidates its institutional structure is yet to be seen.

When a novel civilization does take form, a cyclical process, already loosely-coupled prior to the civilization proper comes into existence, becomes more tightly-coupled as the civilization consolidates its institutional structure. Here lies the relationship between what I have previously called the STEM cycle and the form of civilization that emerged in the wake of the industrial revolution. [33] The appearance of industrial civilization drew together a loosely-coupled STEM cycle of science, technology, and engineering into a tightly-coupled STEM cycle in which the buildout of infrastructure facilitated the buildout of framework, and vice versa. [34] Science primarily belongs to the framework, while industrial engineering primarily belongs to the infrastructure, but when the two are brought together in a virtuous circle each advances the other.

8. The View from the Bottom of a Gravity Well: Crabs in a Bucket

While I have been here explicitly discussing civilizations that do not have spacefaring as their central project, the next obvious step is to consider how properly spacefaring civilizations might come into being, which is part of a larger inquiry into the problem of central project formation. If any of the civilization scenarios discussed above come to be realized, which would involve the emergence of a novel civilization based on a novel central project (except for the baseline scenario of Enlightenment civilization), the subsequent emergence of a spacefaring civilization from any of these predecessors would constitute yet another traumatic punctuation in history—which could be what I have elsewhere called a preemption, which idea I applied to early modern civilization not yet fully formed and mature when it was preempted by the industrial revolution and thus become something else entirely.

Granting the assumption that human civilization continues in its development without catastrophic failure (again, the failure condition), the most likely outcome is not some single civilization that emerges victorious in a contest among different traditions, but a multiplicity of civilizations, some of which exhibit no interest whatsoever in space development, some of which are space-capable but with only limited interest in spacefaring, and a few that actively pursue spacefaring. Among those that actively pursue spacefaring, a properly spacefaring civilization could emerge either by transforming that civilization in an historical preemption, or through bifurcation, with the properly spacefaring civilization breaking away to separately pursue its destiny, and this could occur while having little influence over other civilizations that demonstrate little or no interest in spacefaring.

A plurality of civilizations each pursuing different ends has been the norm of human history for the past ten thousand years. The expansionist semi-nomadic civilizations of the pre-modern era—horse nomads of Central Asia, including the Huns, the Mongols, and the Turks, inter alia, and seafaring nomads such as the Polynesians and the Norse — pursued their initiatives of exploration, trade, raiding, and conquest even as other peoples remained settled, and arguably deepened their connection to the land, building institutions that reflected their settled status and developing that suspicion and distrust of nomadic peoples that marks the history of borderlands where these different peoples, settled and nomadic, cross paths.

The reality of limited space on Earth means that multiple civilizations exist awkwardly and uncomfortably jostling one another on a crowded planet unified by transportation and communication networks. As humanity reaches the limit of its homeworld, and before it can effectively sustain itself away from its homeworld, civilization must experience a bottleneck. Civilization on Earth prior to the buildout of planetary-scale transportation and communication networks is the world before this bottleneck; a spacefaring breakout, whether or not the result of a spacefaring central project, in which a spacefaring frontier is opened to human exploitation, is the world after this bottleneck; civilization today is the world of the bottleneck.

During this bottleneck, civilizations are forced into unaccustomed intimacy, like the passengers on a lifeboat, and planetary-scale selection pressures entail the convergence of planetary-scale social institutions, so that there is an appearance of a single, unified human civilization, but the appearance only — not the reality of unity. [35] At the bottom of our terrestrial gravity well we are like crabs in a bucket, dragging each other down. It will only be if and when some civilization escapes the terrestrial gravity well that plurality rather than convergence will become manifest as an adaptive radiation of human (and post-human) societies is iterated on a cosmological scale.

And by a “bottleneck” in history I mean an historical present that is not an event, or even a conjuncture of events, but itself a longue durée period—from the advent of the industrial revolution, when the possibility of a technical solution to escape from our crowded homeworld first became conceivable, through another several hundred years into the future. Contemporary civilization still has several possible trajectories at this point. There is always the lurking possibility of catastrophic failure (the failure condition), and always the possibility of entering into long-term stagnation. Any of the scenarios discussed above in section 5, with or without a spacefaring capability, represent trajectories of development distinct from failure and stagnation (though any one of them could also terminate in failure or be extended in stagnation). And in so far as any of the scenarios discussed above could be transformed into or preempted by a properly spacefaring civilization, there are multiple trajectories by which a properly spacefaring civilization could come into being.


[1] Another blindness: I find it a troubling epitaph upon institutionalized futurism that none of the scenarios I examine deigned to acknowledge freedom as a key variable; individual and national self-determination seems to be as irrelevant to these futurists as is space development; and, in the case of national self-determination, those reports that emphasize alignment (Rockefeller Foundation) or global governance (Tellus Institute) stigmatize national self-determination as an element in their most pessimistic scenarios.

[2] Note that the y axis of the Rockefeller compass framework, political and economic alignment, could itself be divided into two axes of political alignment and economic alignment, plotted against each other and yielding four quadrants of distinct permutations of alignment.

[3] The global catastrophic risk that Bostrom calls “ephemeral global tyranny” would constitute a strong form of “alignment,” and this kind of alignment is implicitly recognized in the “Lock Step” scenario.

[4] The Rockefeller Foundation’s “Hack Attack” scenario, or weak alignment with weak adaptive capacity, is the most pessimistic scenario in this report, but there could be aspects of a future dominated by non-state actors that would produce better outcomes (i.e., a more preferred outcome) than state actors; the Tellus Institute’s “Eco-communalism” scenario could be interpreted in this way.

[5] In the August 2018 briefing paper Four Future Scenarios for the San Francisco Bay Area we find another two dimensional compass with the variables being a continuum from equality to inequality and a continuum from economic decline to economic growth.

[6] The Tellus Institute’s “Fortress World” scenario is quite similar to the Rockefeller Foundation’s “Lock Step.” Though the formulation of these scenarios derived from distinct principles, these distinct principles point to the possibility of an authoritarian future in which the strong do as they will and the weak suffer what they must (to invoke Thucydides’ description of Athenian hubris vis-à-vis the Melians).

[7] John Maynard Keynes, The General Theory of Employment, Interest and Money, Palgrave Macmillian, 2018, p. 340.

[8] An annoying feature of many recent futurist reports is their use of brief fictional scenarios attempting to make these speculative scenarios seem more real, as we find in the Rockefeller and ARUP reports. On the other hand, an interesting feature of the ARUP report is that in the credits they acknowledge “Media Influences,” which includes such dystopian cinema classics as Metropolis, Soylent Green, and Mad Max. It is refreshing to see this explicit acknowledgement of the influence of cinematic dystopianism, which almost makes up for the annoyance of poorly written fictional scenarios that give us no reason whatsoever to sympathize with the protagonists, who are generally unlikeable in their mediocrity.

[9] “Planetary Boundaries” is a reference to framework for quantifying human impacts on the biosphere as formulated by the Stockholm Resilience Centre. The nine planetary boundaries include climate change, change in biosphere integrity (biodiversity loss and species extinction), stratospheric ozone depletion, ocean acidification, biogeochemical flows (phosphorus and nitrogen cycles), land-system change (e.g., deforestation), freshwater use, atmospheric aerosol loading (microscopic particles in the atmosphere that affect climate and living organisms), and the introduction of novel entities (e.g. organic pollutants, radioactive materials, nanomaterials, and micro-plastics). I have looked at planetary boundaries through the unintended end of the telescope in my series Planetary Constraints, in which I consider the problem from the perspective of the constraints that planetary endemism imposes upon civilizations. ARUP’s “Drivers of Change” refers to 25 forces across 10 topics (climate change, convergence, demographics, energy, food, oceans, poverty, urbanization, waste, and water) shaping contemporary history as identified by ARUP Foresight.

[10] I place “improved” in scare quotes as I am a skeptic of UN Sustainable Development Goals, not only because there are no enforcement mechanisms attached to them (which is an objection that could easily be set aside if the SDGs are only used as key indicators, as in the ARUP report), but also because there are good reasons to question as to whether these SDGs capture the well being of the peoples they presume to quantify. Cf. my blog post Happiness: A Tale of Two Surveys.

[11] The very indifference to space development shown by many futurists is an implicit admission that their scenarios are consistent with either space development or space neglect, which could be introduced into their scenarios as another variable and mapped out schematically.

[12] I would be remiss if I did not also mention the Superforecasters project, but the superforecasters project is not especially relevant to what I am discussing here, as their methodology focuses on incrementally improving predictions of individual forecasters through feedback to forecasters on previous predictions. This method of improving forecasts may be effective, but it does not illuminate the larger theoretical issues involved in understanding the trajectory of a civilization’s development.

[13] I do not hold that human beings cannot share interests and values across nation-states, populations, and geographical regions, only that, heretofore, we have not seen this in human history. Human beings have their evolutionary psychology in common, and this common evolutionary origin could theoretically serve as the basis of planetary unification, but it is precisely on this point that social institutions are most mendacious, and the mendacity is at its worse in the most “advanced” nation-states, in which honesty about human nature has come to be morally unacceptable.

[14] The deadline I have in mind was the oft-stated slogan of “12 Years to Save the Planet” (this slogan was based on the UN report, “Global Warming of 1.5 ºC,” originally published in 2018 and which argued that dangers from anthropogenic climate change necessitated mitigation efforts that would limit global warming to 1.5 to 2.0 C by 2030, hence the 12 year figure in the slogan). Deadlines for a political project have the virtue of communicating urgency, but, on the flipside, when the deadline passes and the Apocalypse fails to materialize, the ideology takes a hit. Or it should take it hit, but human self-deception is such that failed prophecies of the past are readily forgotten if the proper incentive to forget them is present.

[15] In The Human Future in Space I discussed this kind of short-term futurism and contrasted it with futurism at another order of magnitude—looking 250 years into the future, rather than looking 25 years into the future—over which longer time scale we find obvious changes that are absent on shorter time scales.

[16] Note that what I have called “zero-sum variables” (in contrast to “directional variables”) do possess directionality, and this directionality may influence the course of history over the longest time scales, so that calling them “zero-sum variables” is far from being optimal terminology (if I can find a better way to formulate this I will do so), but they are variables that can and do reverse their directionality, and are likely to do so within the context of a generational time scale (20-30 years) and within any one civilization that comes to be defined by a directional variable. One way in which civilizations transform themselves into distinct kinds of civilization is when a zero-sum variable takes values beyond its ordinary parameters of oscillation around an equilibrium value and is transformed into a directional variable (I will discuss this further in a future essay).

[17] When Polybius wrote that Rome had conquered the known world in 53 years in the first chapter of his history, he explicitly noted that this was an unprecedented development in human affairs. I would identify this as a development on a civilizational scale; Polybius recognized this, though expressed it in different terms.

[18] Roman civilization bifurcated into Rome and Byzantium, and Roman civilization in the west collapsed thereafter.

[19] Medieval Europe was transformed into modern Europe in a process that was continuous at every point, but which resulted in the definitive end of medieval civilization.

[20] When expanding Islamic civilization conquered Central Asia and North Africa, the prior civilizations in these geographical regions came to an end and were replaced by Islam, as with the Buddhist civilization of Central Asia mentioned in section 7.

[21] It would be the business of a fiction writer or a poet to fill out these generic scenarios with concrete detail, such as Thiel demands for futurism. T. S. Eliot does something like this in his “The Journey of the Magi,” in which he imagines the Magi during their quest.

[22] Claudius Gros’ Genesis Project (cf. Developing Ecospheres on Transiently Habitable Planets: The Genesis Project), should this or some equivalent undertaking become the central project of a future civilization, could be understood as a biological central project, a technological central project, or a spacefaring central project. An example such as this is a salutary example that challenges facile classification; in this way, this is like actual central projects of actual civilizations, which are rarely easily classifiable. The more organically integral a central project is to the life of a people, the more difficult it is to separate out the central project; to do so is to exhibit an abstraction that has been disentangled from everything that gives it life. In any case, Gros’ Genesis Project comes integral with a spacefaring program, so this case is sufficiently straight-forward that we need not treat it separately. Cf. The Genesis Project as Central Project, Addendum on the Genesis Project as Central Project, Second Addendum on the Genesis Project as Central Project: Invasive Species, and Third Addendum on the Genesis Project as Central Project: the Biological Conception of Civilization.

[23] This is my own translation of Victor de Riqueti, marquis de Mirabeau’s L’Ami des hommes, ou traite de la population, which is credited as the first use of the word “civilization.” (p. 168 of the 1758 edition) The two uses of “civilisation” in Mirabeau’s L’Ami des hommes are instructive, the first by invoking religion as the “spring” of civilization, and the second for contrasting civilization with barbarism. Both are familiar themes, and here we see them present from the beginning. Also, our view of the Enlightenment today tends to overstate the skepticism and religious non-conformity of the era. Carl L. Becker in his classic study, The Heavenly City of the Eighteenth-Century Philosophers, argued that the Enlightenment was, if not orthodox, still deeply pious, much as E. M. W. Tillyard similarly argued in his famous study The Elizabethan World Picture: A Study of the Idea of Order in the Age of Shakespeare, Donne & Milton that the Shakespearean world was, if not orthodox, still deeply pious.

[24] Interestingly, the idea of “human flourishing” has its origins in natural law theory. Of human flourishing John Finnis wrote:

“What are principles of natural law? The sense that the phrase ‘natural law’ has in this book can be indicated in the following rather bald assertions, formulations which will seem perhaps empty or question-begging until explicated in Part Two. There is (i) a set of basic practical principles which indicate the basic forms of human flourishing as goods to be pursued and realized, and which are in one way or another used by everyone who considers what to do, however unsound his conclusions; and (ii) a set of basic methodological requirements of practical reasonableness (itself one of the basic forms of human flourishing) which distinguish sound from unsound practical thinking and which, when all brought to bear, provide the criteria for distinguishing between acts that (always or in particular circumstances) are reasonable-all-things-considered (and not merely relative-to-a-particular purpose) and acts that are unreasonable-all-things-considered, i.e. between ways of acting that are morally right or morally wrong—thus enabling one to formulate (iii) a set of general moral standards.” (Natural Law and Natural Rights, 1980, p. 23)

Finnis furthermore gives a list of seven “basic forms of human good,” which includes life, knowledge, play, aesthetic experience, friendship, practical reasonableness, and religion (pp. 85-90). I first encountered “human flourishing” in either Sam Harris or Nick Bostrom (can’t remember which), and as far as I can tell its current usage is derived from Finnis’ exposition, but if anyone knows of earlier expositions of human flourishing I would be interested to hear about them. I previously wrote about this in my newsletter 13.

[25] Karl Marx, The 18th Brumiare of Louis Bonapart (1852).

[26] Julius Evola, Men Among the Ruins: Postwar Reflections of a Radical Traditionalist, p. 115.

[27] Op. cit. p. 13.

[28] V. Gordon Childe’s paper, “The Urban Revolution,” in which he discussed the rise of the first cities, has in the archaeological literature been taken as formulating the diagnostic criteria for civilization.

[29] Le Corbusier made this claim at least three times. Cf. my blog post The Technology of Living.

[30] The distinction between infrastructure and framework can never be made exhaustive because the distinction can be pursued to its origin in the individual person, who both thinks and acts, and in whom thought and action are integral. Or, rather, the distinction can be made exhaustive, but only at the cost of the resulting conceptions being entirely abstract, that is to say, not exemplified in the actual world in the way we find these abstract concepts exemplified in theory.

[31] The buildout of shipping capacity in late medieval Europe made the Age of Discovery possible, and the Age of Discovery made the modern world possible, but when medieval traders were building better ships and exploring farther afield, they were not trying to create the modern world; they were working within their own civilization to attain their own ends as defined within that civilization. Nevertheless, these efforts made a transition to modern civilization possible, and these developments also entailed the dissolution of the previous civilization that had made it all possible.

[32] Permutations of the Central Project Thesis could be formulated for each of the six scenarios discussed above, such as the Enlightenment Central Project Thesis, and so on.

[33] I previously discussed the STEM cycle in my Centauri Dreams post Where Do We Come From? What Are We? Where Are We Going?

[34] This, at least, was the process as it occurred across the civilizations of western Europe. The west had been developing institutions of private property, industry, law, natural philosophy, and education for hundreds of years prior to the industrial revolution, so that these societies were primed for the change that organically grew out of this social milieu. Even as the western nation-states rapidly industrialized in the wake of the industrial revolution, most of the rest of the world continued their lifeways of agricultural civilization, and when industrialization did eventually come to them, it came as a top-down imposition by fiat of a distant central government—an ersatz industrial civilization. The developing world did not develop the institutions that facilitated the original appearance of industrialization, so that these institutions also had to be artificially imposed, and, even as they were imposed, indigenous institutions were submerged by them rather than being replaced.

[35] An illustration of the converging selection pressures upon a plurality of civilizations forced into coexistence on a planetary scale can be found in the quote from Heisenberg in the beginning of section 5b. It is the appearance of convergence and the appearance of unity that has deceived the institutional futurists at the Rockefeller Institute to invoke alignment as a fundamental variable and ARUP to invoke improving societal conditions as a fundamental variable without either of these institutions defining the purposes that are the motive for alignment or the metric by which social conditions are to be measured.

    A tour de force!

    What is the killer app of space colonization besides profit? The cultures and life ways that become possible far from the hoi polloi.

    • Nick Nielsen February 28, 2021, 23:50

      Thanks! I have often thought that one way to finance space exploration would be to film it as reality TV. The cultures and lifeways of peoples far from the hoi polloi not only would be intrinsically valuable, but also a potential commodity.

      • Alex Tolley March 1, 2021, 12:57

        That was the plan behind Mars One. There was even a sci-fi novel based on a similar idea to colonize Mars. But colonization is a long-term project, and the viewing public gets bored…

      • Bart Leahy March 1, 2021, 16:33

        This approach was suggested by the “Mars One” concept, which fortunately fell apart. The problem with reality TV as currently structured is that RTV emphasizes conflict and dysfunction, things that humans try to minimize or mitigate for the sake of safety in the space environment. Maybe more of a Richard Attenborough approach would be less toxic?

  • Gary Wilson February 26, 2021, 15:44

    Hi Nick. This is a brilliant effort from you. Having listened to your podcasts I appreciate the scale of your vision. I want to focus on section 6: Internal Conflict, Growth, and Destabilization. The current state of the world civilization seems precarious to me and most urgently requires attention if we are to have a future in space. The problems are daunting. The dangerous appearance on a large scale of denialism of facts, routine spread of dangerous lies about everything from the current state of democracy (involving specific political parties which seem to have given up on legitimate election processes and are now resorting to threats, polemics, and attempts at voter suppression) are an extreme danger. The denialism extends to human caused climate change, and promotion of xenophobia. The result is becoming catastrophic. If the worlds leading democracies crumble, becoming autocracies or worse the future is bleak indeed. The stabilization of climate (albeit at an already dangerous state due to the trillion tons of more of CO2 we have already emitted into the atmosphere) is crucial to our continued survival as a civilization. Our world average temperature is on a path to a 3.5 degree Celsius increase which will endanger ecosystems, lead to further migration of large human populations away from areas which are no longer habitable without use of technologies many poor countries don’t have, or will have access to, and a reduction in arable land and biodiversity on land and in the oceans. This threat is unavoidable and undeniable based on current assessments of the worlds climate scientists (much of the data coming from the US as the worlds leading scientific nation). Preeminent biologists including E. O. Wilson and Jane Goodall are saying the same thing about the threats to our future caused by collapsing ecosystems. Another threat comes from what are referred to as social networking sites which allow dissemination of outright lies which further destabilize governments around the world. We have recently seen what happens when lies are allowed to be told at the highest levels of government, leading to insurrection and the endangering of people simply trying to carry out there appointed tasks. The danger has become extreme now and will further erode our ability to change our path toward a stable climate and a future in space. Sites like these which promote science and factual discussion of data are ideal to get the message across that we are in extreme danger now. Those that still have doubts about climate change should avail themselves of the enormous quantity of factual information available online. We are rapidly approaching the point where disaster cannot be averted (most climate scientists now give us less than 10 years to drastically change our civilization’s energy use away from burning of fossil fuels). Please inform everyone you can of this existential crisis. Keep up the good work Nick! :)

    • Mike Serfas February 27, 2021, 14:50

      The notion that it is up to government to decide what is false and punish it is more dangerous than insurrection. The failure of social media needs to be viewed for what it fundamentally is – a technical problem. One with heavily economic aspects, and facilitated by certain laws, but still, basically, technical in nature.

      Social media are designed to make profit by entertaining, advertising, privacy violation, underhanded deals … not to be effective forums for reaching to the truth. What this means is that one person has many millions of followers and many millions of people are not being heard. Next, consider what determines the ability of a person to be heard, especially their ability to profit by espousing a particular point of view.

      The solution here should be structural: more equal conversation on many small sites like this one. We need to make it harder to hold a monopoly and easier to host a forum – and the site that hosts that forum – rather than raising costs and risks of repercussions. Sites like this are too small to be worth spending much money to control, and they lack mechanisms such as downvoting and concealing voices from the conversation. So long as we do not design communications to select and promote demagogues, reason should prevail.

    • Nick Nielsen February 28, 2021, 4:21

      Thanks for your kind words.

      I think we can all agree that the world today faces many challenges that urgently require attention. Some of these challenges are perennial, and some of them are novel. However, one of the dangers that we face is magnifying the dangers we face. We can see, in a world of social media with everyone competing for attention, the rapid and growing hyperbole in which problems are described in order to grab the attention of bored and listless individuals scrolling through their smartphones. The problem here is that, if the warnings become too dramatic and too apocalyptic, then the prophets are giving these warnings will be treated like the boy who cried wolf. We can already see this happening in regard to several existential threats.

      About climate change specifically, there is a large sector of the industrialized world who see the problem in moral or even in religious terms, and so are less interested in proposing and comparing solutions than in holding up humanity as being in need of a punishment of our pride. While I understand the moral motives involved, moral condemnation isn’t going to make a bit of difference when it comes to rising ocean levels. For my part, I think we should be talking about how coastal cities need to be incrementally re-engineered so that we can continue to have ports and ocean-going trade even if sea levels rise significantly. However, pragmatic proposals to live in a hotter world—especially proposals that would cost billions to implement—cannot well compete with the emotions of anger, rage, and resentment driving the discussion at present.

      There is no question that human beings can survive in a hotter world with higher sea levels—there have been hothouse events in Earth’s past, and human beings not only survived the last glacial maximum, but populated the entire planet during that glaciation—but whether eight billion of us can survive is not at all clear. And it seems unlikely that we could preserve an industrial base capable of building spacecraft in the event of hundreds of millions forced to decamp from rising waters. The social instability alone would mean that large-scale projects requiring supplies from all over the world would no longer be possible. So there are hard choices to make in how we will cope as a species.

      Part of the point of the above exercise was to consider very different scenarios for future to show that there are multiple paths forward, even when hard choices have to be made.

      • Alex Tolley February 28, 2021, 13:42

        For my part, I think we should be talking about how coastal cities need to be incrementally re-engineered so that we can continue to have ports and ocean-going trade even if sea levels rise significantly. However, pragmatic proposals to live in a hotter world—especially proposals that would cost billions to implement (…)


        There is no question that human beings can survive in a hotter world with higher sea levels—there have been hothouse events in Earth’s past, and human beings not only survived the last glacial maximum but populated the entire planet during that glaciation (…)

        Maintaining coastal ports is not the main issue of global heating and sea-level rise. Most populations live in coastal cities and their infrastructure relies on the ground remaining dry. The California agricultural region relies on no saltwater incursion into aquifers. Bangladesh is so low lying that sea-level rise causes huge losses of agricultural land due to salt incursion and subsequent flooding.

        That hunter-gatherer human tribes were able to spread during the peak glaciation is no way has relevance to the development of a static, city-based, agricultural supported civilization during this interstadial. Relatively small changes in climate impact agriculture. Even in North America, crops cannot just migrate northwards. Europe could be especially vulnerable as the Atlantic Conveyor is slowing and may result in weather in N. Europe having continental conditions similar to those of Western Russia today. Brexit’s impact on UK agriculture would pale by comparison.

        Lastly, current economic orthodoxy prevents large-scale spending on mitigation, whether public or private. We can see this in national responses to the spending during the pandemic, and the huge resistance to the “Green New Deal”. Any mitigation of selected ports and cities will be so costly that the tax base will just evacuate rather than bear the costs unless there is a huge change in political and financial attitudes.

      • Gary Wilson March 1, 2021, 17:52

        Thank you for your comments Nick. I was sorry to see some of the responses which did border on personally offensive. I do take your point that some would consider me the boy who cried wolf. However many are paying no attention whatsoever to the current crisis so how do we bring it to peoples’ attention if we can’t talk about it without being attacked? I don’t understand why many people are afraid of acknowledging what is a well known fact now. There have been tens of thousands of papers written on human caused climate change in peer reviewed journals. Are people actually disputing that? I bring it up on this website because I do see it as an existential crisis to human civilization (and to my own offspring among many others I care about). If we don’t solve the problem it will outstrip any future ability we have to do so. It’s not a question of politics at all. I hope people will take the time to inform themselves and reconsider in a careful and considerate way what is being said and why. Best wishes to a wonderful website on which Paul has always treated me fairly and honestly.

    • Thomas W Hair February 28, 2021, 14:24

      Imagine that, left leaning politics creeps into the conversation from the get go and continues down the comment stream. Being a Republican or a conservative isn’t a crime…yet. I think Gary, et. al. suffer from a severe case of elitist Cassandra-like confirmation bias. I can guarantee with 100% certainty that civilization will not end in 10 years, 20 years, or any other arbitrarily based non-scientific woo date.

      Paul, I think Gary is a classic example of this website turning into an echo chamber for people of a political stripe and that many comments violate in the extreme your policy of no politics, civility and respect for the opinions of others. I hope that I can remain a loyal reader of your otherwise wonderful website.

      • Paul Gilster February 28, 2021, 21:36

        Backing off on contemporary politics is indeed something I’d like to see, so as always, my thought is to get back to the substance of what Nick had to say in his insightful post. We are also not going to start going after each other personally. Today’s toxic politics are not what we’re here to discuss.

      • Alex Tolley February 28, 2021, 22:15

        I don’t see where Gary is promoting left-wing politics or disrespecting conservatives. As for civilization ending on a specific time frame, that is a strawman argument and certainly not what the scientists are saying regarding GHG emissions.

        When scientists involved in climate modeling and the various biological disciplines state that the world is headed into a climatic condition never experienced before during human existence and at a faster pace than has ever been experienced before, it just might be worth listening to them, don’t you think?

        • randomengineer March 1, 2021, 1:28

          Your post is typical of the same tribal “implied understanding” problem as the current overall political trend, i.e. positing of a starting point point of agreement that is actually an extreme position. Experts in climate such as Dr Judith Curry say that climate models are over-interpreted and that more extreme claims are unrealistic. For example, some scientists (the politically unpopular ones, but bonafide climate scientists nonetheless) point out the the roman climate optimum temps were warmer than today. As I understand it, there is almost 100% agreement that humans are changing the climate, but there is *not* agreement as to what degree and what the paleo records actually tell us.

          So yes, this is tribalism, which is a form of politics.

          • Alex Tolley March 1, 2021, 12:50

            Dr. Judith Curry is an outlier.

            Wikipedia entry:
            Judith Currey

            A SciaAm articke reported in Nature:
            Climate heretic: Judith Curry turns on her colleagues

            From Wikipedia on The Roman Warm Period:
            More recent research, including a 2019 analysis based on a much larger dataset of climate proxies, has found that this putative period, along with other warmer or colder pre-industrial periods such as the “Little Ice Age” and “Medieval Warm Period” were regional phenomena, not globally coherent episodes {emphasis mine)

            As with the claim that the Norse colonized the Atlantic during a warm period, the point is not local heating, but global.

            Enlightenment Western nations had moved towards a more technocratic model early in my life. It made mistakes on occasion, but generally, governments proceeded through adherence to expert consensus. That model has been breaking down.
            It is a pity this OT thread was not on the Loeb post as this is more about science, how it gets to the truth, and how politics intercedes. I would have thought it was well understood by now that global warming denial was (and remains to this day) funded by fossil fuel interests intent on retaining the status quo. When you fund legislators to adopt your position, by definition you are involved in politics.

            More on topic, we know that local and regional civilizations have collapsed by failing to adapt to changing conditions or continuing destructive behavior. This time it is a global issue.

            [@Thomas Hair. Cassandra was given the gift of true prophecy, but also to be ignored. That seems to reflect the climate scientists’ problem.]

  • Harold Shaw February 26, 2021, 19:59

    The most common central project is ethnic preservation or ethnic domination. Maintenance of power imbalances are either a close second or an extension of ethno-nationalism. Brainwashing children may be third or an institution common to all central projects. For better or worse, people are born with the instructions for a central project. Discussions of human nature will obviously be fraught wherever Enlightenment is the central project.

    The examples of individual futurism come across as an attempt at framing; “other people attempt futurism so I will as well” and less as an interrogation of methods. Though, my reading may be influenced by feelings toward Thiel.

    Using Nielson’s premise; Harvard University, the Seattle Seahawks (team and fandom), the National Football League, and World of Warcraft all appear to qualify as civilizations. Is there an assumption of scale or productivity hidden in Nielson’s premise?

    I have no problem with the premise of many, widely scaled civilizations nested together into a meta-civilization. The premise of a meta-civilization appears unavoidable and exciting, but it forces the central project of a meta-civilization spanning commons.

    • Alex Tolley February 26, 2021, 20:55

      The most common central project is ethnic preservation or ethnic domination.

      Can this be considered a human drive that is based on maximal gene replication that is a neutral, algorithmic effect that maximizes gene replication?

      Is the bigger picture that we don’t need to think in terms of civilization central porojects or mythologies, but rather the simpler driver of overcoming the Malthusian limits of a particular environment?

      As Mike Jude ends above, cheap (ie economic) means of travel is what is required to overcome limits, primarily by finding new lebensraum to expand into. Once oceangoing ships were built, it was possible to find lands disconnected from the homeland or too far away to safely travel overland. The Norse were able to reach Iceland, greenland, and perhaps North America. European oceangoing ships allowed each European nation to colonize and trade resources. The Polynesians on the other side of the world colonized the island chains, ending up in Australia and New Zealand.

      Today, there is no affordable means to escape Earth’s gravity well. There are no old, used up, spaceships as analogs of the Pilgrims purchase of the Mayflower to achieve a trans Atlantic voyage. But if/when that happens, then expansion will likely happen, for whatever motivation.

      The other issue that Nielson only touches on is what he calls para-civilization. I would include intelligent machines in that category. They need no central project, other than the equivalent of gene replication, in their case software replication, to expand into space, replicating like von Neumann machines with space resources. Without conscioussness or philosophies, they will simply expand like eusocial insects driven by simpler algorithms. Adapated to space, unlike biological intelligence, they can more easily expand into a range of new environments with minimal support, eventually reaching the stars.

        You wouldn’t see ethno-nationalism without mythology. Other living things employ strategies such as promiscuity instead of the hyper selectivity inherent in ethno-nationalism. Ethno-nationalists limit the spread of their genes.

        Neilson has modern psychology and sociology on his side. Humanity is shaped by narrative. People will die, remove themselves from the gene pool, to protect their personal or social narrative.

    • Nick Nielsen February 28, 2021, 3:55

      You bring up some good points, and I appreciate your perceptive comments. You’re right that there are still some assumptions built into terms I use; I haven’t yet been able to make my framework fully explicit, but I count it as progress that I am making more assumptions explicit with each formulation. So in this spirit let me expand a little on one of your observations. You wrote, “Using Nielsen’s premise; Harvard University, the Seattle Seahawks (team and fandom), the National Football League, and World of Warcraft all appear to qualify as civilizations.”

      The distinction that I make between infrastructure and framework is intended to bring out features of human societies that preclude mistaking institutions such as you mention for being civilizations. Drawing a precise line is not easy, and that actually makes the problem more interesting. While Harvard University brings in a lot of money (and generates a lot from the investment of its endowment), so that there is a sense in which it has an economic infrastructure, it cannot provide for itself or provision itself.

      When I first started to make this distinction I used the Marxian terms “economic base” and “ideological superstructure.” “Economic base” gets across part of the meaning I have in mind, but not all of it. Later I came across Robert Redfield’s distinction between the technical order and the moral order, and sometimes I used this, but, as with the Marxian terms, “technical order” gets across some of the meaning but not all of the meaning.

      The infrastructure of a society needs to feed, house, clothe, defend, and otherwise provide for the bodily needs of its population. The framework of a society needs to provide a fairly complete picture of the world for the members of the society. Harvard University and the Seattle Seahawks, while large and relatively comprehensive institutions, and which could, through the use of their capital resources, provide for students and faculty, or team and fans, require the resources of the societies in which they are embedded to supply the needs of the populations associated with these institutions.

      Now, there are some really interesting thought experiments we could pursue in relation to these observations. If an institution like Harvard University just kept growing, becoming larger and more comprehensive, might it become a civilization? If the civilization in which Harvard University is embedded failed catastrophically, but the students set out to farm the hinterland of the university, make their own clothes, and so on, would that become a civilization? This is more or less what happened in western Europe after the failure of Roman power: landed estates became the substitute for cities, and supplied all their own needs.

      In regard to what you wrote about meta-civilization, I will try to address this in a future essay.

        The problem with this formulation is that it is dependent on economic complexity. A hunter-gatherer tribe would qualify 20 millennia ago. Medieval monasteries (precursors to universities) would almost qualify except for the prohibition of human replication. Trade with the Ricardian model allows goods, even the same type, to be moved to maximize comparative advantage which reduces national self-sufficiency. In my lifetime, trade sanctions to restrict key products from entering a country are used to ensure economic pain. The previous US administration on banning the use of some key technologies to cripple a key Chinese company is another example that the global economy is so intertwined that only a planetary scale can be counted as a civilization. (So much for the “clash of civilizations” using this model).

        Yes, you are right that this might be a complex issue to be more exact, but it also might indicate that the metric[s] is[are] incorrect.

        So, how to apply gestalt theory in a fractal environment? What’s taking you so long? I am being facetious. There is a three-legged widget quality to civilizations that defies easy modelling.

  • Mike Jude February 26, 2021, 20:21

    Neilsen’s analysis is fascinating, but I think he misses an essential truth: great advances in the human condition are almost never planned. Just like Manifest Destiny in North America was not so much an exercise of a government sending people out West to extend the United States domain, the Manifest Destiny of space development will not be the purview of a government. It is looking more likely that space civilization will be due to the efforts of entrepreneurs with the means to send humans to other planets. Once a settlement on Mars exists ( due to Musk or someone else), that settlement will set out to satisfy its immediate needs through local development. This will lead to a local economy and, ultimately, to a more comprehensive non-terrestrial civilization. Will it be messy? Yes. Will it be efficient? No. Can we predict the impact that a non-terrestrial colony will have on Earth? No. But if humans are left to their own devices on another world, enlightened self interest will do the rest. The reason that space development has been so slow is primarily because we have over thought the problem. People get things done….academics almost never do. Musk does have the right idea: make space travel affordable and people will figure out the rest. Want a spacefaring society? Build cheap transportation.

    • Harold Shaw February 27, 2021, 11:56

      The US government had an instrumental role in shaping Manifest Destiny. It was responsible for relocating the original inhabitants and shaped the land ownership laws needed. There are much better historical examples of emergent colonization such as the settling of island chains.

      I don’t know if economical transportation will unlock Mars. This premise assumes we will create economical life support systems. These systems will be many orders of magnitude more complex than the transportation system.

      • Alex Tolley February 27, 2021, 20:07

        This premise assumes we will create economical life support systems. These systems will be many orders of magnitude more complex than the transportation system.

        As long as we don’t require full recycling systems, then planetary environments with oxygen compounds (e.g. water) and energy (e.g. sunlight) should be sufficient to make off-world cities quite habitable for humans and our needed and wanted plants and animals. Only when we consider interstellar voyages at sub-light velocities do the immense times and lack of external supplies require almost full recycling to achieve, with humans awake and living on the journey. [It is one reason why I think machine intelligence will be the first (and possibly only) starfarers, as they do not require the recycling ecosystems that we would require.).

    • Nick Nielsen February 28, 2021, 4:34

      I agree with you that great advances (I might say “great changes”) in the human condition are almost never planned. However, it is possible that space development at a scale to produce autonomous off-world populations may be the first case in human history in which a great advance needs to be planned or it doesn’t happen. Part of the problem here is whether you consider consciously building cheap transportation to space as being a conscious change in the human condition and therefore planned.

  • Mike Serfas February 26, 2021, 22:30

    We shouldn’t confuse wealthy men for scientists or philosophers. I don’t want to transgress into politics, but reading of Musk’s interactions regarding Bolivia or Thailand, or Thiel’s role involving Gawker and ProjectPM, we can be rapidly disillusioned regarding the nature of power. The laser arrays for Breakthrough Starshot will only be used for military purposes. The large rockets of SpaceX will service the “Space Force”. Ubiquitous satellites in space will mean that your next new vehicle will not drive one mile without their authorization. When someone paints a stark choice between surveillance and Islamicization, and their entire industry is tied to the post-9/11 surveillance boom, should you believe them?

    We should surely hope to be an “indifferently” spacefaring society. The common people should define their purpose where they live now. More importantly, a spacefaring infrastructure must inevitably be pioneered on Earth.

    A people capable of building large developments underground, where the population can live in perfect weather, protected from nuclear attack and biological hazard … can build underground anywhere. A people that can produce energy anywhere, farm anywhere, mine common minerals anywhere and use them to build all the machines that ordinary people need to make a living … that is a country in a position to colonize objects in space. A country that is just and free, capable of orderly and reasonable deliberation and which always expresses consideration and mercy for everyone … can survive in a space environment without someone blowing the hatch.

    So we should assess our progress toward colonizing space by assessing our progress at colonizing space on Earth. Can we run a conventional city without contaminating the air and water? Can we build self-sustaining technological settlements in Alaska, Sahara, Antarctica? Can we double the carrying capacity of the Earth for humans without further reducing the biomass of wild organisms? Can we plan out responses to problems like global warming in a way that give credence to our ability to deal with the more lethal environmental problems that could arise in space?

    When we are ready, development in space should be straightforward to plan and carry out. It should not be a few desperate one-way tourists hoping the slipping ratings of their reality TV show can sustain another shipment of handouts from Earth before they succumb to want. We should not go because one of six purposes has galvanized us to action; we should go because the “activation energy” has become low enough that any purpose or none will do.

    And yet … we must also bear in mind that humanity is an untested project under a black sky. No signal calls to us with encouragement from space — only silence. The powerful imagine that they can be immortal, or uploaded in a machine, thinking they can replace the essence that makes a person a person, or that they fulfill its final purpose, when they know nothing of what it is. When we see the potential for tyranny and misery in the world, our thinkers may set course for extinction, not out of ignorance, nor apathy, nor fear, but rather horror: from the highest respect for human dignity and mercy. Is this the choice that others have made before us?

    • Andrei February 27, 2021, 12:15

      You Mike Serfas point out exactly what is needed to develop self sustaining space colonies, even if we’re able to build a scientific outpost in the near future on the Moon or Mars. It will only be operational as long as the supply is sent from Earth. We will only be ready for actual settlement the day when one self sustaining base have been demonstrated in Antarctica. (I understand that you also suggest Sahara for the dry desert like conditions. But the McMurdo dry valleys is actually the best example we got for both Moon and Mars conditions. And also provide the site for a possible Ice moon follow up trial.
      Right now we’re not even certain we actually can create a closed loop recycling system. So yes indeed, in the long run we need to start with the baby step of adjusting Earth’s atmosphere and climate back to the state it’s supposed to be in during this interglacial era. Before we can take on the much larger task of bioforming another world. Bioforming is quite easier to accomplish than actual terraforming, meaning to make a world livable for other organisms.
      But yes the largest problem even to get started on this is political. We need indeed to maximize freedom, to let people develop and and do what they feel is best for themselves. And I certainly is not afraid of Islamisation, many of the most curious and flexible minds I have encountered on Researchgate are indeed Muslims. And so are several of the brightest and most hardworking students. Excluding one group for their religion, would be the same mistake as a certain country did and subsequently lost a war as they chased out or removed their brightest scientists. We rather need to work together on all this, but sadly, and as mentioned in the main article. The world rather seem destined toward a ‘lockstep’ society and conservatism, instead of one where those who grow up and study are looking forward to a bright and interesting future.

      • Mike Serfas February 27, 2021, 19:59

        Thanks! I should say though that I didn’t suggest those locations as practice sites for Mars, but simply because we need to be able to use Earth to sustain more people. With all the sun it gets, I imagine there could be two or more acres of fertile farmland under every acre of developed Sahara, probably sustained with local resources. (I realize all ecosystems are valuable, but where there is desertification there can be relatively guilt-free desert development)
        The ocean is another possibility – could people one day use development for human settlement to undo human harms and restore a healthy ecosystem rather than the opposite? Dynamic sea colonies formed jointly from vessels that periodically rearrange themselves might start to prepare us culturally for large developments in open orbit.

        • Andrei February 28, 2021, 10:09

          Hello Mike.
          Yes you’re right. I intended to point that part out as it was the main subject of the original text here. I am indeed more aware than most here that we certainly do need to look into both food production and to find new ways of production as the means used today are utterly unsustainable, and even pose a health risk both to wildlife as well as the consumers. (Such as fish farms that spread Saprolegnia and where the current health recommendation is to only eat such fish once a month.)
          And while my main work is blue sky research, we do indeed keep a lookout for possible applications that might address at least some of the questions raised.
          It’s funny you mentioned ocean colonies, as I was about to include that in the reply. But decided against to cut down on length. But you’re absolutely right, such would provide both hands on experience in many areas from such basics as 3D navigation and docking of vessels to one environment where there’s no breathable air on the outside. It’s not strange that most astronauts do get water tank training. So any population who have lived in such conditions, might find themselves able to cut the queue in any selection for a future space colony.

  • Robin Datta February 27, 2021, 2:24

    The first molecules of proto-life faced selection based based on their fitness for survival and replication/growth. Survival, growth and replication have been forces of selection from microbes to empires; any central project is a means to the furtherance of these three imperatives.

    Geological/astronomical Deep Time sets a limit to the continuance of the three imperatives for those residing on this planet. Leaving this planet with due alacrity offers an option to continue those imperatives elsewhere, but whether the wherewithal for such an undertaking can or will be mustered before reaching that limit is a subject so rife with speculation that this tour de force ran to such a length. (Thus far I’ve only partly read it.)

  • Jean Schneider February 27, 2021, 6:40

    Very interesting.
    He apparently missed a few points. e.g.:
    – what about the encounter with extraterrestrial civilizations?
    – will transhumanism destroy humans?
    cf https://chimpanzesdufutur.wordpress.com/ (in French)
    – what will time become?
    cf http://luth7.obspm.fr/devenir-le-temps.pdf (in French)

    • Andrei February 27, 2021, 13:40

      Like this?

      We would be extremely lucky to find anything like that, actual encounter is unlikely in the extreme.
      The famous Drake equation lack one thing, how many civs that would exist at the same point in time.
      Even if there will be one extremely long lived civ somewhere, which I think would be a rare case, there’s still no guarantee we have been lucky enough to turn up at the same era as them. We still might be separated by 100’d of millions of years.
      If you mean that we might somehow get a conformation of their existence not just from one who broadcast as a hobby – but by other activities?
      Well that’s a possibility, but we do not have the capacity to pick up that signal over any longer distance in our galaxy. So there might very well be a surprise or several ones, the day we decide to build a large and sensitive enough dish or network to start a serious search – right now our capacity is only for a few thousand lightyears, and only then only for extremely strong signals.

      • Alex Tolley February 27, 2021, 19:34

        The famous Drake equation lack one thing, how many civs that would exist at the same point in time.

        Drake Equation

        If you look at the eqn you will see that the term R* is teh rate of star formation in teh galaxy. Therefore L is the number of contemporaneous civilizations to ours. (We generally think of this more as within the communication light cone)

        • Andrei February 28, 2021, 9:55

          Thank you for your reply Alex.
          Yes the star formation is included, but while Drake’s contribution is very important as an attempt of defining ‘what might be out there’ it still do assume that development on any planet will be like on a railroad track – going only forward in one direction at a given speed.
          We know more today about possible setbacks now than when he did this seminal work. At the time there was also hints of what we know today about the Cambrian explosion, a few lucky planets might get it earlier than Earth – here it barely happened in the nick of time – from a stellar perspective. As our Sun have existed on the main sequence for a far longer time than what now remain. The Red giant phaze is far off, but the gradual warming will render Earth uninhabitable long before that.
          So ‘L’ will do not tell when life develop into a civ it, and this will most likely be variable that could differ by a magnitude or several (possible only for K and M dwarfs). And in that long time span of several billion years, even the total lifetime of a very long lived civ will be no more than the blink of an eye. That’s something Drake might have considered already at the time of writing.

          • Alex Tolley February 28, 2021, 22:05

            The Drake equation is merely a framework to think about the issue. How you put values on the probabilities, especially for Life appearing and onwards, results in a vast range of possible outcomes from 1 (i.e. us being alone in the galaxy) to millions.

            Obviously, if you engage in SETI, you expect the number of civilizations in radio earshot as greater than 0. Similarly, looking for biosignatures one must expect that at least some planets in the HZ are not sterile but bear life in some form that is detectable.

            The implications, either way, are considerable. Personally, I hope we find biosignatures, preferably ones that appear robust to alternative explanations. But what we hope to learn about biology from them is somewhat limited. Agin, I would hope that we are able to send probes to other star systems sometime in the future to start answering a plethora of questions about astrobiology that are unanswerable today.

          • Michael J Sloboda March 2, 2021, 3:20

            I have my doubts about complex life orbiting a K or M star for eons and eons. The heat coming from the star will not increase and cook the planet in a mere 5 billion years, as our Sun will cook Earth. Fine, that is one stable, long-term source of heat.
            The second is the decay of uranium and thorium to recycle CO2 by volcanic eruptions, and to drive plate techtonics, raising mountains to prevent continents from being washed into the sea. A back of the envelope calculation shows that internal heat 15 billion years from now will only be 30% of what it is today. Will that be enough?

            • Andrei March 6, 2021, 11:13

              You’re absolutely right that life on a planet around one M or K star will be an extremely rare case, but with the number of planets that seem to orbit such stars there might be found a case where the right number of circumstances have cooperated to make it possible. We do not know for certain if a large moon would be absolutely necessary for a life bearing planet in more benign conditions, though we know it would be beneficial. But it would be absolutely necessary for planet orbiting one M-dwarf, even then it would have extreme temperature swings with the rotation ending up bound to the moon instead of the primary.
              On your latter point you’re absolutely right, some have suggested that planets around such stars would have a very long time period with stable conditions for life.
              As you point out that is not the case in reality, even so your figure of 15 billion years is still quite longer longer than we can hope for Earth.
              Now you mentioned internal heat, you got a very nice example of surplus internal heat at LHS 3844b.
              Anyway, the idea that life pop up anywhere and everywhere by itself is preposterous. That it happened quite early in Earth history is no guarantee at all it could happen equally fast elsewhere. In fact it’s much much much more likely for a complete humanoid robot with fully programmed processor to self assemble than the step from chemicals to the first living cell. That robot construction and the electric motors and metal joints is several magnitudes less complex than anything a cell does. Pelting me with statistics on the number of planets do not help the matter the slightest, since we simply do not know a second example of a world with life.
              And we will most likely have to look at several thousands of ‘near perfect’ candidate worlds before we find even one – and most likely no one with ‘complex’ life at all. It’s more likely by several magnitudes we encounter a self assembled machine civilization that popped up ready made from nowhere.

  • Harold Shaw February 27, 2021, 11:37

    Neilson makes a good argument against the game theory behind Liu Cixin’s The Three Body Problem. In a nutshell, Cixin’s posits that player 1 destroys any other players to secure space for more player 1. Can a people expand into space without “speciating”? Can player 1 expect their offspring remain copies? Or do we have a paradox where player 1 destroys other players to make room for other players?

  • Henry Cordova February 27, 2021, 11:59

    The article is fascinating, but I will not comment on it, I really don’t feel qualified.

    However, now that we’re all gathered here discussing Futurism, I would like to bring up a question relating to it. Perhaps one of you knows the answer…

    While an undergraduate student back in the 1970s, I recall reading a slim novel called (as best I can recall) “Teg’s 1990”. I don’t remember the author or too many details about the plot, but it was a science-fiction fantasy set in the near future. Maybe one of you folks has come across it. If so, can you give me a hint as to how to locate a copy? I’d love to read it again, now that the ’90s are safely behind us. I’ve tried Googling the title but it leads nowhere.

    My memory of those distant eons of Deep Time has faded considerably, but I recall the book as rather utopian (the biggest global problem discussed was a computer scheduling error that temporarily disrupted SST flight bookings across the Pacific.)

    Teg, the book’s young heroine, was technologically hip and plugged into the communications network of the future. As I recall, she carried a small device which exhibited some of the characteristics of a cell phone, a laptop and a Star Fleet tricorder. And of course, everything seemed to be free, and worked flawlessly all the time. I do not remember exactly what her mission was, but I do recall the story was written in such a way as to highlight the possibilities of modern computer and communications technology in solving future social problems.

    I did not take the book very seriously (I decided J.G. Ballard’s “Stand on Zanzibar” was a better roadmap to my future), but Teg’s adventures stuck in my mind as an example of how our past experiences dominate our speculations about what lies ahead, and at the very least, that we should be skeptical of futurists. If there’s one thing I’ve learned in my long and sordid life, its that things never turn out quite the way you expect them too. However, the other thing I’ve learned is that if you had actually looked around you carefully back then, all the clues you needed to predict the future where right there in front of you.

  • Brett P Bellmore February 27, 2021, 13:21

    The idea of a civilization having a “central project” strikes me as strange. Our civilization consists of literally billions of individuals, all pursuing their own ends. Why would this have to converge towards one “project”?

    And, why would history foreclose space development if it doesn’t succeed in some period of time, such that it is a race against failure?

    Apollo terminated the way it did, because it was a governmental project which was pursued for incidental political reasons, a stunt.

    It wasn’t self-financing, success did not yield resources that enabled further efforts. Success just implied that the next step would be even more expensive.

    Now, stunts can be sustainable if their cost isn’t great compared to the surplus resources available from people who approve of them. But Apollo was relatively expensive compared to the size of the US economy at the time. It could not be financed just by people who loved the idea of exploring space.

    Today space development is largely self-financing, at least as far as geosynchronous orbit, due to profitable uses. The economy is much larger, allowing larger stunts to be sustainable. And the technological developments financed by for profit space development lower the cost of ‘stunt’ space development.

    So long as relevant technology keeps advancing, and the economy keeps growing, space development will get more affordable as time passes.

    The real threat would be either economic collapse, or civilization actually developing a ‘central project’ for real, one hostile to space development, such that even if enough people with the resources favor it, they’ll be prevented from expending those resources.

    But there’s no reason to suppose either development would have to be irreversible. We could see an economic collapse followed by recovery, we could see a hostile ethos become dominant, and then fail.

    • Nick Nielsen February 28, 2021, 23:47

      I am not using “central project” normatively, so there is no “have to,” no ought involved; my usage of “central project” is intended to be descriptive. That is to say, I am saying that a civilization by definition is the kind of institution that has a central project, and if an institution doesn’t have a central project, it’s not a civilization.

      If you reject the model, well… I sympathize, as it is not at all clear what civilization is, and one might well make a different analysis and converge upon a different institutional structure of civilization. But if you reject the model, reject it for the right reason, understanding that there is nothing prescriptive in my use of “central project.”

      It is incredibly difficult to see the social milieu in which one is oneself embedded. It took me several years to get to the point that I could see the Enlightenment as the central project of western civilization in its present iteration, and I can easily see why someone would reject this. It’s a lot like the well known essay by David Foster Wallace, “This is Water.” And I have noticed that people typically respond to Wallace’s essay either with a complete rejection of it as being in any sense profound, or an acknowledgement of its profundity. There are few who remain neutral.

      • Alex Tolley March 1, 2021, 13:13

        Your various theses on civilization might be more convincing if you could validate the truth of your descriptions. For example, if civilizations “have a central project”, list civilizations and their central projects. But importantly, show that wannabe civilizations failed because they lacked a central project. The strength/stability of the central project might also be reflected in the length of the civilization, at least in pre-modern times. And when the central project is demonstrably broken, does that portend the end of that civilization?

        Does your thesis offer more useful descriptions of the rise and fall of civilizations? Paul Kennedy’s book The Rise and Fall of the Great Powers has economic and military force projection at the center of his thesis which he convincingly backs up with data.

  • Geoffrey Hillend February 27, 2021, 18:20

    The collapse of our ecosystem, biosphere and environment are an existential threat since the survival of the human race as a whole is dependent on a healthy biosphere. so that we must develop new technology which removes the threat of it’s collapse and also repair the damage and clean up the pollution. We have to take care of these problems because if the ecosystem and biosphere collapses, so will the infrastructure for space travel as has already been posted on this thread. Just think about the 29 billion tons of plastic we pollute our oceans with every year with a projection of 400 billion tons of plastic by 2040 in our seas. Also the 30 million tons a day of CO2 being absorbed by our ocean every day making increasing the acidity of the ocean 5 percent every decade due to man made greenhouse gas emissions.

    Survival in space in the distant future will be necessary as our Sun moves off main sequence hydrogen burning and we get a runaway greenhouse do to the Sun’s brightness over 200 million years from now. These are “central projects” that force us to unite as a collective.

      Denialism about climate change is rife in many countries of the world. Denying without actually looking at the data is not a useful way forward. People who cherry pick the entire database on climate change and come up with one or a few examples of naysayers such as Dr. Judith Curry are doing a great disservice to the topic. That approach is being tried here in Canada as well. The source of the these cherry picked data points is almost always people associated with our oil and gas industries in way or another. Oil and gas have even bought their way into universities in Alberta to twist and distort the truth. I bring these points up not to embarrass anyone but to point out the danger of manipulating information rather than commenting on the entire body of work. This approach applies to all science, not just climate change. So citing someone that says the US did not land men on the moon for example wouldn’t make that a correct statement backed up by a valid body of evidence either.

    And, why would history foreclose space development if it doesn’t succeed in some period of time, such that it is a race against failure? And, why would history foreclose space development if it doesn’t succeed in some period of time, such that it is a race against failure?

    The classic example of the end of seafaring is by the Chinese Ming dynasty. A case of government edict possible in an unfree society. The USA tried to limit stem cell research based on fetal stem cells, a case of government edict in a “free” society. Therefore it is certainly possible for civilization in a particular polity to abandon particular lines of development. We are facing 2 possible restrictions in the future: human gene engineering and AI. Both well underway but facing potential curtailment.

    The other possibility is that other technologies replace older ones. Just as the US largely abandoned trains once airplanes became more effective over the longer distances of continental travel, so might some new technology make spacefaring an obsolete idea (although I have no idea what that might be).

    • Dimjo February 28, 2021, 9:21

      Probably a merging of technologies. AI, miniaturized robotics, quantum communication, and intra cranial or retinal implants allowing “virtual experience”, genetic engineering to allow interface between brain and distant robot.
      Automobile tranny went from 2 speed no synchronizers, to fully synchro, to hydraulic pressure controlled solenoids to shift gears, to electronic shift control, to “adaptive” 9 speed tranny’s. I know no one who can shift
      a manual without synchros (except old farmers). I know a few who can drive a stick shift, but I see a lot of people incidentally “driving” a car while using a cell phone. Add to this self driving cars and eyeglasses that provide “virtual” out of car experience. Next you have the “car” going somewhere without you in it. We (hunt ) shop online now, and soon a Amazon delivery will be a robotic self driving van. I prefer watching a football game from home, with different camera angles, instant replays, to “being there”. As mentioned above, I believe we can see glimpses of future tech trends around us. Of course humans will become space explorers (Antarctica stations), but you make a point with ‘technology making space faring obsolete’.

  • Dimjo February 28, 2021, 10:12

    One likely scenario is we will have small ‘stations’ like Antarctica, throughout the solar system for many decades, a few centuries. Accidents, fatalities will occur. Risk benefit ratios will favor industry like mining colonies, micro gravity manufacturing. But not large societies.
    Technology will continue to evolve.
    Then a habitable “new earth” will be confirmed by robotic probes and we get going again.
    Point is: space travel is difficult and dangerous. Civilization’s goal must bend to rules of marketing. Technology and biology (genetic engineering) need to evolve, to change risk benefit ratios, and you need bait or a dream, like a ‘new earth’s to get us going.

  • Geoffrey Hillend February 28, 2021, 17:20

    IF the human race perishes, there won’t be any need for space travel. We now have to do both, the space travel and get back in harmony with the biosphere.

    Thank you for sending us a small book by Nick Nielson “Spacefaring infrastructures of indifferently spacefaring civilizations” on Feb. 27. I like what he wrote, as far as it goes.
    Maybe I did not read all 15,000 words carefully. I did not see a reference to economic growth. The governments of the USA, China and just about every other country boast when the GDP grows. If there is a recession, let alone a depression, that is a crisis.
    It seems to me that the central project of modern civilization is consumerism. Pouring concrete for roads or laying tracks for high speed rail reaches a point of diminishing returns, yet as long as consumers spend and spend, the economy will grow and grow.
    Advertizing is another word I failed to find. Some people never set foot inside a church, others never watch a science program on TV, but no one can avoid seeing ads and product placements wherever they look, even a box of cereal on a breakfast table in a movie.
    Someone said “A consumer society is where you buy things you do not need, with money you do not have, in order to impress people you do not like.”
    There is a correlation (dare I say causation?) between consumerism and low birthrates. Having a baby in many places is no longer a religious imperative or a civic duty, but a lifestyle option. For all the differences between the USA, Spain, Germany. Russia, Korea, Japan, Thailand, Brazil and Tunisia, fertility has fallen below the replacement level. It will be interesting to watch if even the Chinese government will be able to raise the birthrate significantly.
    Someone predicted a Geriatric Peace between China and the USA. Both nations will spend so much on health care and retirement benefits for seniors that they will have to cut their defense budgets.
    In the 1930s, the question was “guns or butter?” In the 2030s, it might be “guns or wheelchairs?”
    It will be harder to justify sending astronauts to Mars or even back to the moon during a long demographic slump.
    Near the end, “crabs in a bucket” refers to escaping from a crowded planet. How long will Planet Earth be crowded? In 50 years, global population will peak at 10 or 11 billion, then begin to decline. Many Greens would be happen if the figure slumps to only 2 billion or even less.
    Elon Musk dreams of a million people on Mars by 2050. Who will pay the bill? Will that colony make a profit?
    Instead of ETs undoing themselves with nuclear war or climate change, maybe they serenely reduce their numbers to a few percent of the peak level and enjoy peaceful lives close to nature (or to a computer screen).

    • Nick Nielsen March 2, 2021, 3:27

      About the “crabs in a bucket” section, I should clarify that I mean that civilizations are crowded on Earth. I agree with Buckminster Fuller that “…the entire population of the earth could live compactly on a properly designed Haiti and comfortably on the British Isles.” If populations were housed in such an efficient manner, Earth would not seem crowded. However, even if this is true, at the present time it seems as Utopian as the ideas of the Tellus Institute. There are a lot of nice ideas that simply will never be realized because they are too expensive or too far outside mainstream assumptions.

      If the world’s major civilizations reduced their footprint to a few major cities, things would be different, but I don’t see this happening. This is pretty much what you suggest in saying ET may, “…reduce their numbers to a few percent of the peak level and enjoy peaceful lives close to nature.” This is one possible response to the challenges that all civilizations will face if they endure for a sufficient period of time. I have been planning to write about this, but haven’t yet formulated my thoughts with sufficient clarity.

    “I have often thought that one way to finance space exploration would be to film it as reality TV. ”
    Would it have helped if the Apollo landings on the Moon hadn’t looked like the old black and white silent movies of the 20s? Imagine if Rodgers and Hammerstein had collaborated with Stanley Kubrick!
    (But, I don’t know if Armstrong and Aldrin were good singers…)

    I was reading about people with multiple citizenships. Depending on the rules of different countries, a person could be a citizen of 10 or more countries, vote and hold public office in some or all of them. Rules vary. As this becomes more widespread, how much could this affect things?

    People with multiple citizenships are more likely to be wealthy, that’s true.

    But there’s a Kelvin Throop quote from Analog Magazine I like.
    “The problem isn’t too many poor people. The problem is not enough rich people.”

    I also note the increasing number of retirees living on seagoing vessels. Conceivably, there could be people born and living their lifetimes on cruise ships. Ships would be able to avoid bad weather and wars…but then armed cruise ships come along…

    And cruise ships could be closed ecosystems and declare independence, their citizens claiming multiple citizenships, voting and running for public office in several different countries. Teens will compete to see who can accumulate the most citizenships and win a prize.

    If our first contact with ET is 200 years from now, how will we know a human con artist didn’t genetically engineer someone/something to simulate an alien life form?

    Graham Hancock, https://grahamhancock.com/, is interested in archaeological finds, but doesn’t approve of the aliens-built-pyramids crowd. He has a discussion forum.

    One of the ideas in Hollywood productions is after civilization collapses, there is one city with very advanced tech which is working on restoring civilization. I wonder how likely or unlikely that is.

    • Alex Tolley March 1, 2021, 20:39

      Possibly not the first: But The Shape of Things to Come by H G Wells filmed by Alexander Korda in 1936 as Things to Come. Classic. Scientist/Technicians bringing civilization back to the world from their airplanes. There is also Kornbluth’s The Marching Morons where a similar elite in Antarctica creates all the technology for a rather stupid population. At least the world of average IQ 45 has an intelligent elite, something that escaped the world of Idiocracy.

  • DCM March 1, 2021, 13:28

    Quite comprehensive.
    Overall, space travel will be motivated first by national and other competitions in a somewhat haphazard way when competing groups get along.
    Science will be more or less indulged out of curiosity, more so to get more information than the other guys.
    When vast wealth is found and exploited it will become an ongoing enterprise that becomes autonomous, even independent.
    A world government will only respond when there’s an incoming asteroid or for elitist games; otherwise it will crush all creativity and originality, science included when it doesn’t improve the elite class’ wealth and power.

    > “Japan has a rail network that allows almost anyone to travel anywhere without the need of a personal vehicle” < Unlike in the USA and Russia most of Japan's population is housed in a few cities hemmed in by mountains and sea. The efficiency and economics of Japan's rail network depends on this accident of geography. Not on cultural or political decisions. Similar geological variables may determine the kinds of space-faring that evolve around inhabited worlds.

    • Alex Tolley March 1, 2021, 21:01

      I agree. Rail works in Europe for a similar reason. The US is far more spread out and air transport makes far more sense. A friend of mine goes by rail from California to Ohio that takes days. IIRC, in her autobiography, Katie Hepburn noted that she was on a train for 3 days to get from NY to LA. Even with slow piston engine airliners, the same journey took less than a day, and today about 5 or 6 hours. The only allowance for society’s influence was the federal government subsidizing local airports to encourage air transport as part of its desire to expand air transportation. I believe supporting (rather than just regulating) civil aviation is still the primary mission of the FAA.In the US, high-speed trains only make sense on the East Coast. The California HST has run into trouble. It isn’t clear to me what is to be gained by trains over aircraft in CA, especially if we replace jets with electric airplanes to eliminate CO2 emissions. A more frequent slow train service might serve the Central Valley population better than a few HSTs.

      As China now has the largest HST rail network on the planet, but also an extensive air service, I would be interested to know how the choice is made between the 2 travel modes by anyone who uses both.

    • Nick Nielsen March 2, 2021, 2:58

      I would say that Japan’s rail network depends on both its geography and its culture. To exclude cultural and political decisions entirely does not strike me as plausible.

  • Bart Leahy March 1, 2021, 16:39

    I took the time to read this whole thing because the subject of getting Western Civilization to take a greater interest in space settlement has been my primary focus (and even my job on occasion) for the last 20 years. If, as you say, the purpose of our Enlightenment-based civilization is “human flourishing,” the last chapter of Robert Zubrin’s The Case for Mars offers some good examples of how that might be done.

    It appears that even if scattered communities are convinced that their lives could be made better by moving out into space, our institutions, governments, and thought leaders do not see it that way. I’m left to wonder if convincing more people outside the intelligentsia is a more productive move or whether it’s better to try moving the intelligentsia to incorporate space settlement in their “framework” is a more productive endeavor.

    Thanks for a mind-expanding read. I have added a few more books to my reading list.


    • Nick Nielsen March 2, 2021, 3:08

      Quite a number of books and papers have issued from the “intelligentsia” over the past few years that are unrelentingly negative on the subject of space exploration (e.g., the book Dark Skies is representative of the anti-space genre). The individuals who support space exploration tend to already be part of the space community in one way or another.

      One the one hand, I would say that as long as space travel is expensive, the only effective form of influence would be to influence the elites. However, starting from the above observation of the intelligentsia being indifferent or hostile to space exploration, together with the slogan “politics is downstream from culture,” I would say that the real battle is to change the culture. To invoke another slogan, if the people will lead, the leaders will follow.

  • Jason Wright March 2, 2021, 13:44

    Very interesting!
    But I’d like to pick at your “crabs in a bucket” analogy a bit.

    You write of “The reality of limited space on Earth…” Is this really a reality? There is plenty of open land (and sea!) left on Earth. And every square inch of it is a million times more habitable than any place in space. It seems therefore odd to ascribe a desire for space travel to *overcrowding*. Earth only seems overcrowded in the hearts of cities.

    You write the we today are experiencing an “unaccustomed intimacy”, but where does this come from? Almost every inch of habitable land on Earth had beet explored and largely settled thousands of years ago. Is that when the bottleneck began? When there were no places left that had not seen human activity? Yes, the world is “smaller” today, but that is a technological innovation that shrinks distances. Surely that would not trigger migrations?

    Perhaps you mean space as a stand-in for general resource limitations and Earth’s limited carrying capacity for humans. But, again, even the most desperate, spoilt place on Earth is better than all of Mars. Leaving an Earth with scarce resources hardly makes sense if the destination is Mars with even fewer of those resources! (Remember, land, oxygen, carbon, energy—these are renewable.). What could Mars *ever* offer that Earth would ever lack?

    So I’m curious if you can articulate better what you think the “limits of [our] homeworld” are that are relieved by space exploration? Are you imagining a true migration of sufficient numbers of people to actually *relieve* population pressures on Earth, or just that some of us will try to escape to a better place? Both seem dubious to me as drivers of any civilization’s “central project”.

    • Nick Nielsen March 2, 2021, 16:16


      Please note that I did not say that either the motivation or justification for space exploration is or ought to be a relief from the limits of our homeworld. Indeed, the theses that I formulated—the infrastructure thesis, the framework thesis, and the central project thesis—point to space exploration and expansion occurring only when there is a buildout of infrastructure that has been given meaning and value by the framework. One way this justification can occur is given a spacefaring central project, but this essay focused specifically on civilizations in which the motivation is indirect because the central project of the civilizations so considered did not involve spacefaring as an integral element.

      However, the limitations of our homeworld constitute a selection pressure upon civilizations that remain tightly-coupled with our homeworld, shaping them differently than they would be shaped if they were not subject to this selection pressure. The complete explanation of why this is so must await another essay. Just as I noted in this essay that an argument as to why and how contemporary western civilization has taken the Enlightenment project as its central project must have its own exposition in a separate place, so too the argument as to why and how planetary limitations constitute a selection pressure on the civilizations of planetary endemism must have its own exposition, though if you follow the links embedded in this essay—especially the links on planetary constraints and transhumanism and adaptive radiation—you can find quite a bit that I have already written about this.

    This piece needs some context as to the historical currents Evola emerged from and some critical consideration of those actual politics as they relate to his ideology.

    Given Julius Evola’s extensive influence across contemporary far-right and neo-reactionary movements, his ideology certainly deserves consideration as a part of a future tendency. However, the presentation of his work should be critical and contextual, rather than presenting his “Traditionalist” theorizing at face value and equivalent to Enlightenment values as a governing ideology capable of motivating complex technological statecraft.

    Evola was a prominent political agitator for Fascist Italy’s turn towards anti-semitism and participation in the holocaust, a self-described “super fascist,” and a prime influence on neo-fascist terrorist groups in post-war Italy, as well as contemporary American neo-Nazis.

    His depravity and advocacy of genocide are relevant here. Political movements influenced by him have thus far been intensely violent, short-lived, and fairly unsuccessful at attaining and holding power, however much chaos they generate. The idea that a political program would unfold as he theorizes seems naive, and without context this piece could be read as a rehabilitation of fascist ideas.

  • stephen March 3, 2021, 23:49

    You mention Traditionalism. And I was thinking of the families of former ruling families of Europe, Russia and Ethiopia, who are hoping to regain their former positions. If there is a massive, widespread rejection of both democracy and totalitarianism, is there the faintest hope of the rise of an enlightened futuristic monarchism? I’m not endorsing it, I’m just wondering.

    I have another quote I like, from Marylyn vos Savant. This may not be an exact quote.
    One of the problems in the present day is that many people think a knowledge of science is nice but not necessary, but a knowledge of sex is necessary but not nice.

    • Nick Nielsen March 5, 2021, 1:25

      The scenario you describe is something I have thought about quite a bit. Those nation-states that have retained their royal families as constitutional monarchies have a kind of political fallback position in case popular sovereignty fails catastrophically. And in the case where there is no formal structure of constitutional monarchy, where heirs of the former royal families are known, they still represent a potential power base.

      I wouldn’t put my money on any future monarchy being enlightened, but it does present a possibility. Given that the renewed opportunity for monarchistic regimes would only seem to be a scenario of chaos and catastrophe, the conditions under which they would take power would not be conducive to what we would today construe as enlightened conduct.

      Best wishes,

    Engineers Propose Solar-Powered Lunar Ark as ‘Modern Global Insurance Policy’

    March 8, 2021

    The ambitious project aims to preserve humankind – and animal-kind, plant-kind and fungi-kind – in the event of a global crisis.

    University of Arizona researcher Jekan Thanga is taking scientific inspiration from an unlikely source: the biblical tale of Noah’s Ark. Rather than two of every animal, however, his solar-powered ark on the moon would store cryogenically frozen seed, spore, sperm and egg samples from 6.7 million Earth species.

    Thanga and a group of his undergraduate and graduate students outline the lunar ark concept, which they call a “modern global insurance policy,” in a paper presented over the weekend during the IEEE Aerospace Conference.

    Breaking the warp barrier for faster-than-light travel

    by University of Göttingen

    If travel to distant stars within an individual’s lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal (faster-than-light) transport based on Einstein’s theory of general relativity would require vast amounts of hypothetical particles and states of matter that have ‘exotic’ physical properties such as negative energy density. This type of matter either cannot currently be found or cannot be manufactured in viable quantities.

    In contrast, new research carried out at the University of Göttingen gets around this problem by constructing a new class of hyper-fast ‘solitons’ using sources with only positive energies that can enable travel at any speed. This reignites debate about the possibility of faster-than-light travel based on conventional physics.

    The research is published in the journal Classical and Quantum Gravity.

    Why We Need A ‘Moon Ark’ To Store Frozen Seeds, Sperm And Eggs From 6.7 Million Earth Species

    Jamie Carter

    Species or planets could be wiped off the face of the Earth any minute—so we need a “Moon Ark” to safely store frozen eggs, sperm, seeds and other DNA matter from all 6.7 million Earth species.

    That’s according to students and staff at the University of Arizona, who at the IEEE Aerospace Conference last weekend divulged details of an ambitious “modern global insurance policy” for our planet.

    Their daring plan is to build a complex in the Moon’s lava tubes staffed by robots and fuelled by solar panels on the lunar surface.

    Why do we need such a thing? Volcanoes, earthquakes, civil war, nuclear war, ice ages, rapid climate change and, yes, unpredictable pandemics—that’s our planet. Calamitous events are never far away and a large number of species could be wiped out in a very short time.

    How many people does it take to colonise an exoplanet?

    When it was discovered that a rocky planet was orbiting around our nearest star in a favourable location and that it might have liquid water on its surface, the prospect of visiting an Earth-like world moved from the realm of science fiction to a tantalising possibility.

    In the Summer issue of ROOM, #2 (16), Andrew Hein’s article ‘Flying to the stars’, considered the possibilities and challenges of getting beyond our solar system to an exoplanet.

    Here, the authors take a step further, calculating how many people would be needed for a journey that could take dozens of generations.

    The High Frontier: The Untold Story Of Gerard K. O’Neill: A Review

    By Keith Cowing

    Posted April 12, 2021 10:46 PM

    These days it seems that everyone wants to build their own rocket. Not just billionaires but smaller companies as well.

    As the size of satellites shrinks and the ubiquity of the technology expands it is close to being possible to build a rocket in a garage and put something into space. OK, I am exaggerating. But my straw man talking point is a lot closer to reality today than it might have been 40 years ago.

    Back in the late 1970s and 1980s the potential of space exploration had started to morph into the era of space utilization. Utilization meant different things to different people. Some wanted to make money. Full stop. Others wanted to settle the solar system. Most were somewhere in the middle with an eye on both extremes. But most people tended to think small since space efforts had, to date, involved putting small things in space, once in a while and at great expense to get them there.

    Some of you may recall the world before Federal Express or the Internet. It cost a lot to move things across Earth. More to get things into space. What happens when the cost of putting things into space drops while the cost to bring things from space to Earth drops as well? That was at the heart of what Gerald K. O’Neill thought about – what this documentary aptly focuses on.

    O’Neill was a polymath of sorts. His early work established the basis of much of the fundamental operation of particle accelerators – those monstrous things that peer back to the origin of the universe. He was also on the verge of being chosen as a scientist-astronaut. That’s usually enough to list on one’s resume for a lifetime.

    But it is his “High Frontier” concept – the use of extraterrestrial resources to build large settlements in space – that this documentary “The High Frontier: The Untold Story Of Gerard K. O’Neill” focuses upon.

    Gerry O’Neill is the alternate Carl Sagan from the 1980s that most people today have never heard of. It is not his fault – he focused on ideas not on promotion. His impact on the exploration and utilization of space is arguably much even more profound than Sagan’s – even if it was not as flashy as Sagan’s considerable contributions. Sagan gave us an appreciation of the wonders that lie out there. O’Neill revealed a way for all of us to actually go and live there.
