I agree about Freud. Yeah, he had some crazy ideas, but that doesn't mean you should ignore all his other innovative theories. I took a class on Psychological Theories of Religion (great class) and the prof. loves Freud (maybe a little too much) but we really learned some interesting stuff. Civilization and its Discontents is one of my favorite books. I think Lacan has some amazing ideas and he was directly influenced by Freud.
