“Gödel, Escher, Bach: An Eternal Golden Braid (GEB) is a 1979 Pulitzer Prize-winning book by Douglas Hofstadter that explores the common themes in the work of mathematician Kurt Gödel, artist M.C. Escher, and composer Johann Sebastian Bach. It investigates how cognition and consciousness emerge from hidden, self-referential mechanisms (recursion) in both minds and machines.”

I had a chance to read it 40 years ago, but passed over it because it is rather a thick book and dense. It’s no excuse. Now I have it on order.
