In this article we survey six recent developments in the philosophical literature on free will and moral responsibility: (1) Harry Frankfurt's argument that moral responsibility does not require the freedom to do otherwise; (2) the heightened focus upon the source of free actions; (3) the debate over whether moral responsibility is an essentially historical concept; (4) recent compatibilist attempts to resurrect the thesis that moral responsibility requires the freedom to do otherwise; (5) the role of the control condition in free will and moral responsibility, and finally (6) the debate centering on luck.

1. “All Theory is Against Free Will…” Powerful arguments have been leveled against the concepts of free will and moral responsibility since the Greeks and perhaps earlier. Some—the hard determinists—aim to show that free will is incompatible with determinism, and that determinism is true. Therefore there is no free will. Others, the “no-free-will-either-way-theorists,” agree that determinism is incompatible with free will, but add that indeterminism, especially the variety posited by quantum physicists, is also incompatible with free will. Therefore there is no free will. Finally, there are the a priori arguments against free will. These arguments conclude that it makes no difference what metaphysical commitments we hold: free will and ultimate moral responsibility are incoherent concepts. Why? Because in order to have free will and ultimate moral responsibility we would have to be causa sui, or ‘cause of oneself.’ And it is logically impossible to be self-caused in this way. Here, for example, is Nietzsche on the causa sui.

The problem of free will arises because of the conflict between two inconsistent impulses, the experience of freedom and the conviction of determinism. Perhaps we can resolve these by examining neurobiological correlates of the experience of freedom. If free will is not to be an illusion, it must have a corresponding neurobiological reality. An explanation of this issue leads us to an account of rationality and the self, as well as how consciousness can move bodies at all. I explore two hypotheses. On the first, freedom is a complete illusion. On the second, it is not an illusion, and there is a corresponding indeterminism at the neurobiological level. This can only occur if there is in fact a quantum mechanical element in the fundamental neurobiology of consciousness.

What values, if any, would be undermined by determinism?[i] Traditionally this question has been tackled by asking whether determinism is compatible with free will or whether it is compatible with moral responsibility. Compatibilists say that determinism would not threaten free will or moral responsibility, and hence that people’s values should not be influenced by whether or not they believe in determinism. Incompatibilists say that determinism would undermine free will or moral responsibility, and hence that a belief in determinism should have a considerable impact on one’s values, precluding many popular evaluative beliefs.

In this paper we discuss studies that show that most people do not find determinism to be incompatible with free will and moral responsibility if determinism is described in a way that does not suggest mechanistic reductionism. However, if determinism is described in a way that suggests reductionism, that leads people to interpret it as threatening to free will and responsibility. We discuss the implications of these results for the philosophical debates about free will, moral responsibility, and determinism.
