For the life of me, I cannot see how any atheist could believe in free will. It's not even justifiable with an all sovereign god.
I don't see the logic. Isn't free will less likely if there is a god? There may be internal strictures limiting free will: psychological, emotional, or even genetic, but I think that free will in a hypothetical universe where a supreme being already knows what your actions will be is impossible.
There was a recent podcast by Sam Harris where he explained that your brain decides before you are aware that you’ve made a decision, and therefore free will does not exist. As such, your decisions are a product of your genes and environment. That was basically his argument. Is this the position you’re referencing, or something else? Please explain, OP.
