Free will, agency, and life
Compatibilists and incompatibilists disagree about the impact of two conditions for free will: the condition of alternative possibilities and the source condition. I argue that free will is incompatible with determinism because of the source condition. Whether or not free will requires alternative possibilities, a free agent must be the physical and mental source of his own actions but an agent cannot be the physical source of his actions in a fully deterministic world. However, unlike libertarian incompatibilists, I do not think that free will is compatible with indeterminism, either. Rather, I offer a hypothetical conditional account of how libertarian free will might be realized in the actual world. If life is naturally teleological or naturally intentional, then human beings would realize the physical source condition in the actual world, and assuming that human beings also meet the mental source condition, libertarian free will would be possible.
