Free will and indeterminism: Robert Kane's libertarianism

Drawing on Aristotle's notion of "ultimate responsibility," Robert Kane argues that to be exercising a free will an agent must have taken some character forming decisions for which there were no sufficient conditions or decisive reasons. That is, an agent whose will is free not only had the ability to develop values and beliefs besides those that presently make tip her motives, but could have exercised that ability without being irrational. An agent wills freely, on this view, by being ultimately responsible for how she is currently disposed to act. Kane needs, then, to show how an agent could be responsible for decisions that her deliberations did not guarantee. He must also explain how a decision for which there is no decisive reason could yet be rational, assuming that the responsibility engendering decisions forming the basis of a free will would be rational. I shall argue here that Kane has achieved neither of these goals.
