An argument is presented, based on a common-sense interpretation of an everyday experience, for emergent dualism as the best available account of the origin of the human mind/soul. Emergent dualism is superior to subjective idealism in that it honors the common-sense conviction that the things we encounter have a real, physical existence, separate from our mental perceptions of them. It is superior to materialism in that it allows for our mental states to have real, physical effects, distinct from the effects of the physical states that accompany the mental states. It is also superior to materialism in allowing for a real, unified self that is not merely a collection of physical particles. These features allow emergent dualism to provide a foundation for libertarian free will; belief in such free will is another deliverance of common sense that cannot readily be reconciled with materialism. Emergent dualism is superior to standard varieties of dualism in giving a plausible account of the minds of non-human animals. Perhaps surprisingly, emer gent dualism is superior both to traditional dualism and to standard varieties of materialism in combining readily with theories of biological evolution, in which natural selection promotes both the physical and mental development of complex organisms.

If we have libertarian free will, then it is plausible to believe that the occurrences of certain physical events have irreducible and ineliminable mental explanations. According to a strong version of (metaphysical) naturalism, everything in the physical world is in principle explicable in nonmental terms. Therefore, the truth of naturalism implies that libertarian choices cannot explain the occurrences of any physical events. In this paper, I example a methodological argument for the truth of naturalism and conclude that the argument fails. I then consider additional concerns raised against the reality of libertarian freedom. First, I examine the claim that if a physical event E is not causally determined to occur by another physical event, then there is no way to account for the difference between E’s occurring randomly and E’s being causally determined to occur by a mental event. Second, I consider the assertion that the affirmation of libertarianism is a mind-of-the-gaps version of the God-of-the-gaps objection to a divine explanation of a physical event. Third, I take up the question of whether the inability of libertarians (or anyone else) to pinpoint precisely where the initial physical effects of libertarian choices occur is a good reason for rejecting libertarianism. Fourth, I examine the claim that belief in the existence of the soul or immaterial mind is the result of an explanatory hypothesis to account for how libertarian free choices can causally produce physical effects. Fifth, I look at the traditional objection to substance dualism from the impossibility of causal interaction between a soul and its body.
