Godel, Escher, Bach: an Eternal Golden Braidby Douglas R. Hofstadter
Not sure what i could say about it. felt a sense of accomplishment already that i was able to gobble it down in its entirety. after quite a few "false starts". :-)
It's a "beauty of complexity": exploring human mind in such a comprehensive way that a reader is constantly in need of specialized and deep knowledge in diverse areas from art, music, mathematics, computer, artificial intelligence, to molecular biology. and a "beautiful mind", if not as beautiful as the author's.
And a book of entertainment, too ,despite the difficulty of the topics. The author was forever playing word games/puzzles, embedding small jokes/amuzements, or just generally thinking and writing in informal/playful ways, as branded in the title: "a metaphorical fugue on minds and machines in the spirit of Lewis Carroll".
Also amazing that the book doesn't seem to age, 30 years since its publication. What could I say? One of its kind? Oh, sure.
