Protean Free Will
This paper argues that free will is a purely theological issue, and offers an error theory for the free will debates in analytic philosophy in terms of evolutionary naturalism. I introduce 'protean free will' (PFW) as the ability to play mixed strategies effectively in noncooperative interactions. Thence, I argue that traditional worries about divine foreknowledge, Frankfurt controllers, moral responsibility, and determinism are side effects of selective pressures for unpredictability in our evolutionary past. Finally, I interpret the Libet experiments as showing an adaptive response to such pressures. I conclude that PFW does most things most philosophers want free will to do, conditional on the nonexistence of God.
