Discourse on Method and Meditations on First Philosophy by René Descartes

I read this for school, but honestly I always love Descartes. He's such a personality, and he's a fun writer to read. I haven't read all of his stuff, so I'd probably take issue with some of what he writes (as with every philosopher), but so far he's less problematic than Plato, Aristotle, and most of the rest of them.
