I think he contributed something quite valuable - he pushed people into what we might call 'beginner mind', without which learning is impossible. His main thesis (as recounted by Plato) that any certainty is false certainty and that the only real wisdom comes from acknowledging one's own ignorance seems valuable indeed to me. I wonder what he would have made of today's statistical methods that try to bake that uncertainty in with a kind of recursive meta-certainty.
