Abstract
Antiquated Classical pictures of the universe have been formative in shaping the modern idea that, to the extent change is caused, it is fixed in advance. This idea has played a role in making it seem to many that what we are discovering through science supports the exclusion of free will from models for the relevant neural and bodily changes. I argue that giving up this unwarranted notion about causation opens us to the likelihood that how a person expresses free will offers unique explanatory value. I then briefly discuss some further issues with either including or excluding expressions of free will from our explanations, as well as some implications for AI and everyday life.
