I don't know why, but the topic of "free will" has never been terribly interesting to me. The argument about free will is more interesting than the actual idea, IMHO.

Anyhow, even if I don't think much of it, this topic has been at the center of a long-running debate with some of history's greatest Philosophers. I found this discussion about free will terribly insightful:
