 Much of the philosophical interest in the free will/determinism problem is motivated by concerns about moral responsibility because, it is generally agreed, having free will is a necessary condition of being morally responsible. So if determinism precludes free will, it also precludes moral responsibility. But it’s important to distinguish questions about free will (whether we have it, what it amounts to, whether it is compatible with determinism, whether it is compatible with other things we believe true) from questions about moral responsibility. Someone might believe that we have free will and that free will is compatible with determinism while also believing, for other reasons, that no one is ever morally responsible. And someone might believe that we don’t have free will (because of determinism or something else) while also believing, against conventional wisdom, that we are nevertheless morally responsible. What one believes about determinism and moral responsibility will depend, in large part, on what one believes about various matters within the scope of ethics rather than metaphysics. Among other things, it will depend on what one takes moral responsibility to be (P. Strawson 1962; G. Strawson 1986, 1994; Scanlon 2008; Watson 1996, 2004; Wolf 1990). For these reasons it is important not to conflate the question of the compatibility of free will and determinism with the question of whether moral responsibility is compatible with determinism.
