Ask HN: What is the most mind blowing book you've ever read?

"The Beginning of Infinity", from David Deutsch, in which evolution, Popper epistemology and theory of computation blend into a world view fruitful of thrilling perspectives for humanity. To me, as mind blowing as anything can ever be.

Lots of good essays already, so I'll chime in with some literature/fiction suggestions off the top of my head:

- Borges, Ficciones (http://en.wikipedia.org/wiki/Ficciones); that's the quintessence of mind-blowing literature: an unparalleled mix of genius, culture and crazy imagination.

- Celine, Journey to the End of the Night; a harsh, hopeless journey to the bottom of humanity. It's not an easy read even though the style is so simple. Think Houellebecq, but much better :)

- Dostoyevsky; I was obsessed with him when I was younger. "Notes from the underground" is one of the best introductions to existential nihilism I can think of. "The Idiot" one of the few books that made me cry.

- The Marriage of Cadmus and Harmony; if you're into Greek literature, this book will become your Bible; it requires a lot of attention and dedication though, it's incredibly dense.

Crash by J.G. Ballard.

The Nature of Order - Chris Alexander. Full Stop.

"The Four Agreements" by Don Miguel Ruiz.

This book advocates personal freedom from beliefs and agreements that we have made with ourselves and others that are creating limitation and unhappiness in our lives.
