I respect where Loren is coming from, but I still cling to the belief that we indeed have free will. I realize that our present models for how the universe work suggest that free will is an illusion. Stated simply - how do the laws of physics allow for any "I" to act in a causal capacity in the world? On such a view, our thoughts and actions are determined by the impersonal laws of phyics playing themselves out in our brains.
However, I suspect that our models are incomplete - I see no compelling reason to discard the idea that true free will exists, even though it is a notoriously difficult concept to pin down.
