What we usually view as the physical world is actually a mental model in our mind. Let’s call the mental model the tamed physical world (TPW). We can call the actual physical world the wild physical world (WPW). A flower in front of me is a mental model in my TPW. Its physical entity is in the WPW, not in my TPW as we usually think. If M-theory is correct, the brain of human is only able to detect four of the eleven possible dimensions for the TPW. If the many-worlds interpretation is correct, time is a many-branched tree for mind. The WPW is controlled by its physical laws, so all physical events in the WPW are inevitable. Minds are created by the WPW. So, all events in the minds are inevitable. So, we are powerless to do anything other than what we actually do. This is the view of fatalism. An individual’s good life is not caused by virtue. So, if you want to be fair, you need to admit that every individual in the physical world deserves the same living standard. “All events are inevitable, so whatever I do, the future will not change, so I can do anything.” This thought is incorrect. Because I cannot assume that I have the free will to choose and that the future will not change at the same time.
