If a human being with inner experiences behaves identically to one without inner experiences in what way can inner experiences be said to give rise to our behavior? You're saying our behavior is not effected by our inner experience. I don't see how any other conclusion can be reached other than our inner experience in no way gives rise to our behavior.
