“But it is true that if we look at a glass of wine closely enough we see the entire universe. [ … ] If our small minds, for some convenience, divide this glass of wine, this universe, into parts — physics, biology, geology, astronomy, psychology, and so on — remember that nature does not know it!”
(Feynman, Six Easy Pieces, qtd. in Floridi)

Does Feynman here make a rare mistake, a Cartesian oversight that forgets that a thought, too, is part of the universe? That is to say, of course nature knows it. But then what is knowing if knowing is nature? As nature, as part of the universe, is a thought something self-reflexive, autopoietic, or … thoughtless? Perhaps Feynman is correct.
