I think that one of the coolest things about intellectual projects dealing with the "big" questions is that different disciplines can all bring something to the discussion (for example you might invoke quantum mechanics in talking about free will and determinism, or you might talk about the anthropric principle having something to say about religion). As philosophers, do you spend much time (or feel that you should or want to spend time) studying disciplines other than philosophy (physics, biology, pscyhology, economics) in order to bring different sorts of insight to bear on your work? Do you ever worry that if you don't reach outside your specialty, you might be handicapping yourself? Is it troubling to think that philosophy, in this way, might not be self-sufficient, so to speak? -j. santana
