“At the frontiers of science, philosophy and knowledge, there are many questions where the ability to reason is hampered by the fact that we have only one example to work with. We want to understand the universe but we have only one universe to study. We understand how life forms on planets but we only know of one planet on which life has formed. We want to understand the nature of symbol-rich self-consciousness but it seems like we are the only things around that have it.”
Adam Frank on the NPR “13.7 Cosmos and Culture” science blog
