Scholastic Hylomorphism and Dean Zimmerman

Abstract

I present Dean Zimmerman’s conceptualization of the varieties of substance dualism. I then focus attention on a form of dualism that he has discussed briefly in a few places, Thomistic dualism as he calls it, or hylomorphic dualism, as I call it. After explicating hylomorphic dualism, I consider the two places where Zimmerman says the most about it, finding, in one case, a way to alleviate a worry he raises using the resources internal to hylomorphism, and, in the other case, a general agreement with his categorizing hylomorphic dualism as an intermediary position between substance dualism and materialism. Since hylomorphic dualism is something of an intermediary position between substance dualism and materialism, it stands to reason that it could be susceptible to attack from both sides. Thus, in the last portions of this article I consider the arguments Zimmerman answers against dualism and levels against materialism. I argue that the hylomorphic theorist can answer the charges against dualism at least as well as the other dualists can. I find that the main argument against materialism that Zimmerman provides, if sound, would also show any composite form of dualism to be false, too. Happily, the hylomorphic thinker has a method of denying the truth of the first premise of that argument, and so, of denying the soundness of the argument.
