 Some incompatibilists (e.g., van Inwagen 1983: 204–13) hold that, although we lack good empirical or experiential evidence that we have free will, we nevertheless have good moral reason to believe that we have it. The claim is that we have good reason to believe that we are sometimes morally responsible for our behavior and that moral responsibility requires free will. Together, these claims give us good reason to suppose that we sometimes have free will. However, absent solid evidence for the indeterminism that incompatibilists say is required for free will, if we justifiably believe that responsibility requires free will and that free will requires indeterminism, it seems to some that, rather than concluding that we have free will, we should instead withhold judgment on whether we are ever morally responsible for anything.
