So, for years I've thought of myself as an "existentialist". Admittedly, I've had a hell of a time figuring out precisely what I meant by that beyond some vague sense that philosophy should address things like despair, angst, and life without moral certainty. Lately I've finally come into a conception of existentialism that I think is more coherent and useful. But I'm curious; is anyone else a fan of existentialism, but finds it hard to determine what an existential subject is?
