Most of you have probably read one or two philosophy books you think no one should avoid reading. Feel free to list those books here, along with why you think everyone should read the book.
I guess I should start: there's an essay by Karl Popper on how he came to the idea of falsification as a constituent element of scientific theories, and I think that's a great read b/c the realization that "there are different sorts of theories for different sorts of purposes" isn't a small realization.
