Can we behave as though free will doesn’t exist? What would we do if we believed that all human behaviour (and everything else, for that matter) was determined by causal chains which stretch back to the Big Bang? What would we make of other people’s behaviour? Would we still judge them for bad actions and praise them for good actions? Would we ever punish any criminals? Would we award prizes to those who’ve performed well?
After all, if we don’t believe in free will, all of these actions are not caused by the person themselves. They are caused by a series of causal chains affecting their bodies, brains, and everything else around them, which stretch back a great distance into the past. Unless we’re willing to state that souls or other spiritual entities exist and have some as yet unknown effect on causality, all the best scientific evidence we have points to the fact that free will is illusory. Plenty of people in the world believe this to be the truth. The problem is, however, that these same individuals walk around judging people, praising people, assigning moral and political responsibility as though everyone still has free will. Why?
