The answer is this. This equation is the quantum analog of the classical equations of motion. It reduces the prior physical world of potentialities to a new form that incorporates the newly grasped structural information. The intrusion of true randomness, which is what quantum theory demands, tends to decreases the effectiveness of mind, rather that increasing it. Causally efficacious free will arises in a very different way.
Nature then returns an answer.
I have given the bare-bones of a rationally coherent quantum mechanical description of the human person. I haven't the time to pursue that technical development here. I return instead to the moral issues raised earlier. We now possess such a theory. These resurrected ideas are the foundations of traditional moral philosophies.
