Its true that we learn a lot from science about how we function but there's a danger in thinking knowledge of how we function is the full account of what we are. If you're a chemist who is really interested in the optical properties of certain pigments you could analyse the Mona Lisa and describe it completely but you would never have mentioned the face, which is the meaning of this thing. In that way a neuroscientist can put together an enormously impressively picture of the brain but he would not have described what goes on when we react to another person.
