... Studien-26 THEMES IN MY PHILOSOPHICAL WORK Terry HORGAN University of Memphis This paper is an overview of my philosophical work. ...

Jaegwon Kim argues that one should distinguish naturalism from materialism, and that both should be construed as ontological rather than epistemological. I agree, on both counts. Although I have sometimes tended to slur together materialism and naturalism in of my writings (as is done in much recent philosophy), I do think that it is important to distinguish them. It is a serious philosophical task to get clearer about how each position is best articulated, and about ways that one could embrace naturalism without embracing materialism. British emergentism, for example, seems reasonably classified as a position that is naturalist but not materialist (and evidently the British emergentists themselves construed their view this way). Here are two key tenets of British emergentism, both of which seem to disqualify the view from being a form of materialism without thereby disqualifying it as a form of naturalism: (E.1) There are emergent properties in nature, in the following sense: although (i) these properties are supervenient on certain other properties, the relevant supervenience facts are ontologically sui generis (and hence are unexplainable). (E.2) Emergent properties are fundamental force generating properties , in this sense: they produce additional fundamental forces that affect the distribution of matter, above and beyond the fundamental forces posited in physics. A position worth of the label “materialism,” it seems to me, should preclude both of these emergentist theses. My notion of superdupervenience is intended as a condition that any version of materialism should satisfy, and is supposed to be incompatible with theses (E.1) and (E.2). Although sometimes, as in Horgan and Timmons (1992) and Horgan (1994), the condition is articulated in terms of the need for supervenience to be explainable “in a naturalistically acceptable way” (thereby slurring the naturalism/materialism distinction), what I had in mind was that supervenience relations must be explainable in a materialistically acceptable way..

The paper is a critique of Terry Horgan's transvaluationist theory of vagueness. It argues that Horgan's formulations equivocate between a semantic 'ought' and a semantic 'is'. On one reading, transvaluationism is trivially inconsistent. On another reading, it is consistent, but also consistent with an epistemic account of vagueness. In addition, the paper criticizes Horgan's attempt to recruit supervaluationism as a form of transvaluationism and his argument against vagueness in the world.

Terry Horgan (with D. Henderson and G. Graham) defends a new general metaphilosophical position called postanalytic metaphilosophy (PAM). I raise some critical points connected with the application of PAM to the problem of freedom. I question the distinction between opulent and austere construals of philosophical concepts. According to Horgan compatibilism comports better overall with the relevant data than does incompatibilism. I raise some objections. At the end I argue that contextualism is an inadequate explanation of incompatibilistic intuitions.

In their paper “Mary, Mary, Quite Contrary” (2000), George Graham and Terence Horgan argue, contrary to a widespread view, that the socalled Knowledge Argument may after all pose a problem for certain materialist accounts of perceptual experience. I propose a reply to Graham and Horgan on the materialist’s behalf, making use of a distinction between knowing what it’s like to see something F and knowing how F things look.

Horgan’s perceptive discussion of Freudian psychology, Prozac and evolutionary biology cannot mitigate the problems that seriously weaken his book (Horgan, 1999). While he certainly manages to deflate some of the more outrageous hype surrounding the scientific and often not-so-scientific study of the mind, his criticism of the brain and behavioral sciences contains a number of flaws, some of which I will address below. My response focuses on his discussion of neuroscience. As we shall see, the three mysteries that Horgan believes cripple neuroscience are certainly not as serious as he insists.

In this paper I examine nonreductive materialism (physicalism). This is a position that Terry Horgan favors in his papers and is probably the most widely accepted position in the philosophy of mind in recent decades. In contrast to this, I will argue that nonreductive materialism is an unstable position and will suggest that we can show this using Horgan's own work on the concept of superdupervenience.
