Please don’t take offense at this question, but just what is philosophy? I go to Stanford Encyclopedia of Philosophy and the Routledge Encyclopedia of Philosophy and search “philosophy”, and there is no entry that helps me. I’ll be directed to particular types of philosophy, but nothing that tells me what makes philosophy philosophy. I would have thought that philosophers, who are always asking themselves what makes X an X, would have been able to answer this question concerning their own discipline. Is it simply a matter of semantics—of figuring out the meaning of our terms (like “knowledge”, or “freedom”)? Or is it a matter of metaphysics—of figuring out what knowledge and freedom really are, in the same way that scientists figure out what DNA really is? Is it a matter of figuring out what our concepts are, or what they should be? What are its questions, and what are its methods for discovering answers to these questions? And why should we think that these methods are reliable?
