The question that often comes up in the free will debate is whether the universe is deterministic or indeterministic. Regardless of which one, I argue, free will is entirely incompatible. In a deterministic universe we couldn’t have done otherwise, and in an indeterministic universe that would allow for a change in variables that lead to an otherwise, those indeterministic variables wouldn’t have been “of our own accord” or “up to us”. In other words, we couldn’t have, of our own accord, done otherwise.
But this isn’t enough for some people. Some want to insist that the universe is causally deterministic… period… no questions asked. Others insist on the opposite, that the universe is indeterministic (suggesting that determinism has been “disproven”). It seems being agnostic on these just isn’t good enough for a whole lot of people.
So which is it? Is the universe deterministic or is it indeterministic? And if we don’t know, are one of these options more likely than the other? Rather than give you a direct answer (as I am agnostic here), for this post I want to get into some key talking points that I feel are often missed.
