I have worked on several topics in metaphysics, mind, language, religion, and epistemology. I started out in physics. I was never any good at it, but I did get an MA degree. Then I got a PhD in philosophy and became a professor. But I'm not good at philosophy either. Most people aren't, even philosophers. The best I can do, I suspect, is explain the difficulty in offering plausible and informative answers to certain philosophical questions.
Despite all that, philosophy is extremely rewarding in some hard-to-define way.
