Numerous people have already recommended Hofstadter, so I'll skip to: The Moral Animal, Robert Wright. It looks at how natural selection applies to human cultures. Debt: The First 5,000 Years, David Graeber. History of economic systems. Everything we know about money is one of many alternatives tried somewhere at some time. Where Mathematics Comes From, George Lakoff. Presents the radical notion that math is not a truth we've discovered, but a byproduct of the organization of our brains. It looks at the evolution of the concept of infinity as an example, and so it resembles David Foster Wallace's Infinity and More. I think these books all have the theme that what we think of as reality is just the current point on the random path of our culture's concensus. If that's not mind blowing, I can't help you.
