Psycho-Physical Events

"Reality, according to Heisenberg, is built not out of matter, as matter was conceived of in classical physics, but out of psycho-physical events – events with certain aspects that are described in the language of psychology and with other aspects that are described in the mathematical language of physics – and out of objective tendencies for such events to occur. ‘The probability function…represents a tendency for events and our knowledge of events’  ... The deepest human intuition is not the immediate grasping of the classical-physics-type character of the external world. It is rather that one's own conscious subjective efforts can influence the experiences that follow. Any conception of nature that makes this deep intuition an illusion is counterintuitive. Any conception of reality that cannot explain how our conscious efforts influence our bodily actions is problematic. What is actually deeply intuitive is the continually reconfirmed fact that our conscious efforts can influence certain kinds of experiential feedback. A putatively rational scientific theory needs at the very least to explain this connection in a rational way to be in line with intuition."
