I posted in this forum because of the marathon Non-Prophets episode from a couple of years ago.
The June 7 and June 14 episodes of the Reasonable Doubts podcast are devoted to the topic of Free Will vs. Determinism.
The hosts of RD had made some points about the subject, which a Christian radio show had made objections to. Jeremy Beahan from the RD podcast then went on this show (the Don Johnson Show) to correct their misunderstandings, and this show is the bulk of their June 7 podcast.
Then the June 14 podcast is further discussion. I haven't listened to this one yet.
In the NP podcast from a couple of years ago, I solidly agreed with Denis's points, and the RD folks take the same position but have a more solid foundation of philosophy and psychology to base it on.
If you don't already subscribe to Reasonable Doubts, it's excellent.
