It seems to me that the ‘big questions’ of philosophy are rather easy compared with those of physics. It should be fairly obvious to anyone who has considered these questions dispassionately and critically that there is no God, no soul or consciousness independent of the brain, no objective morality, and no free will. What is far from obvious, however, is how to unify quantum mechanics and general relativity…
Physics is pretty complicated, but I think that most physicists would acknowledge that the individual human brain is the most complex object so far identified in the universe. And to the best of our current knowledge, we are the only species in the universe capable of asking ourselves.
I don’t suggest that the problem of consciousness is as intractable as many believe. At this point, it’s a question for neuroscience, not philosophy, to answer (or perhaps ‘neurophilosophy’). Yon
