“Advanced societies throughout the galaxy probably are in contact with one another, such contact being one of their chief interests. They have already probed the life histories of the stars and other of nature’s secrets. The only novelty left would be to delve into the experience of others. What are the novels? What are the art histories? What are the anthropological problems of those distant stars? This is the kind of material that these remote philosophers have been chewing over for a long time…” — Philip Morrison (1961)

“Will we be able to understand the science of another civilization?… Our science has concentrated on asking certain questions at the expense of others, although this is so woven into the fabric of our knowledge that we are generally unaware of it. In another world, the basic questions may have been asked differently.” — J. Robert Oppenheimer (1962)
