Free will is only a real issue if you think it betokens something else as Alan B does. Otherwise we just assume it since I don't think we can avoid doing so. Not believing in free will is a sort of moebius strip of logic, since if you don't have it, you have no choice in the position.
It's a valid intellectual question, and I have had enough discussions with Leonard to knowledge he does believe it. I think this is inconsistent with his other positions which seem to allow for nothing non deterministic or random, but, in the end, both he and I act as if it were true.
I find the question of, if we do have it, can it allow us to choose what we believe, more significant but then maybe I have no choice in that.
In the end it's a distraction, you might as well accept it and ask what do we do next, but to use it as a crutch for arguments about gods or whatever just seems to pile Pelion upon Ossa.
