What book should I memorize?

[Josh (Josh Cohen)]

I’m adding a link from this thread to another one that lists interesting books (and book lists) so that people can find it:

What Are Your Favorite Books That Changed the Way You Think?

I thought it would be interesting to have a thread about books that are so good, they’ve significantly changed the way you think. They don’t have to be about memory – they could be about philosophy, biology, psychology, sociology, music, computers, economics, or any other topic – even fiction. What are the best books (from a learning perspective) every written? Feel free to post any book recommendations in this thread.
