Godel, Escher, Bach: An Eternal Golden Braid by Douglas R Hofstadter
Following on from Sci-Fi thread and mentioning Jeff Noon, when Noon was asked to give his top 10 reads by the Guardian, this came in at number 3.
"A complex, ticking bomb. This is easily the most difficult book I've ever read. It took me four goes, starting from the beginning each time, and it's 750 pages, just to explain Godel's Theory of Incompleteness. Along the way Hofstadter takes in all human knowledge systems, including Lewis Carroll. Still not sure what it's all about, but that's beside the point. Again, ideas abound. There are passages in here, without which, Vurt would not exist. "
Anyone read this, would you recommend or will I just end up depressed by my own confusion and incomprehension?
