Goedel, Escher, Bach - an eternal golden braid. This book is so rich with philosophical content it will change you.
I really struggled to read this. It's so dense, in an almost impenetrable way. Am I the only one? I did some skimming, but never seemed to catch on.
It’s the kind of book you need to sit down and deliberately read for a while, rather than snatched moments here and there or while waiting for something else.
Personally I found it very informative and interesting - though not ‘enlightening’. I did stop reading it for a while and found it difficult to pick up the thread again though.
