I'm very philosophical, but I don't read philosophy (much) because I don't believe others can think about a given subject better than I can. And when I disagree with them it's frustrating because i have no way to argue back at them or to the public. But from what I'm familiar with, I like Noam Chomsky (Zizek is kinda cool too) and, though he's technically considered more of a psychologist than a philosopher, I'm gonna say Carl Jung.
