This story is physically deterministic in two ways. First, the physical state of the universe (and everything in it, including you) at a particular time and impersonal laws of nature are sufficient to determine or fix the chances of the next successive state. This is temporal determination. Second, the features and behavior of ordinary-sized objects like glaciers, rocks, human beings and animals is fixed by the states of their atomic and subatomic parts. This is bottom-up or parts-to-whole determinism. If genuinely mental consciousness exists, it is a causally impotent epiphenomenon. Among other things, this means that a feeling of thirst never causes someone to get a drink; thoughts and beliefs play no role in directing or bringing about our behavior. Many philosophers right think that if a view implies epiphenomenalism, the view must be rejected.
