In the course of writing a book on Free Will, I took the opportunity to read a good deal of contemporary literature on the Free Will problem. This paper is a survey and reflection on that reading, responding to the current trends and state of play concerning the existence of free will.

In this essay, I investigate the implications for the discussion of theism in philosophy of religion for the beliefs of ordinary Christians and conclude that, in light of its historical development, those implications are minimal.

In this paper I defend the thesis that, considered simply as certain sorts of bodily sensations, pleasure is not the good nor is pain intrinsically evil. In fact, the opposite is largely the case: pursuit of pleasure is generally productive of ontic evil, and pain, when heeded, directs us toward the ontic good.

Although this piece was inspired by the kinds of legal puzzles discussed by Hart and Honore in Causation in the Law, the puzzle cases presented here are intended to test the reader's intuitions about what constitutes murder. Play along!

Aquinas' Third Way is often dismissed as a howler, because he infers from the fact that, since the universe is metaphysically contingent that there was some time in the past when it didn't exist. I offer an argument to justify this inference.

In this paper, I argue that neuroscience not only is not complemented, but rather is positively undermined, by the substantive commitments of materialist philosophers of mind. Thus, we can have neuroscience or "neurophilosophy" but not both. Since neuroscience is a real science, to the extent that it is in tension with materialistic neurophilosophy, the latter should be abandoned and the former retained.

Based on a recently published essay by Jeremy Gwiazda, I argue that the possibility that the present state of the universe is the product of an actually infinite series of causally-ordered prior events is impossible in principle, and thus that a major criticism of the Secunda Via of St. Thomas is baseless after all.

This is the final paper in the Possibilities that Matter series and attempts to complete the project of constructing a material interpretation of modal logic.

In this essay I explore some of the basic elements of consciousness from a substance dualist point of view, incorporating some elements of Kant's Transcendental Analytic into an overall account of the constitution of consciousness.

In this paper I argue that there is no problem of Divine Hiddenness for Christians and offer an alternate explanation for the widespread claim that God's existence is hidden based on the Christian doctrine of Original Sin.

In this paper, I offer a new account of mind/body interaction that shows how it is possible for an immaterial mind or soul to influence a physical system without entering the horizontal system of efficient causes studied by natural science.

In this paper, I present some ruminations on Hume's argument from miracles and the distorted view of rationality that it reflects (along with religious skepticism generally) contrasting it with what I take to be a better account of rationality, one more sympathetic - at least less hostile - to religious claims.

This is the first of a series of four papers presenting modal logic as a branch of material, rather than merely formal, logic.

This essay discusses recent attempts to show that Kant's philosophy is coherent and consistent on its own terms. This paper was read at the annual POH Symposium in Lake Wenatchee, WA in May, 2013.

In this paper I offer an alternative to the standard, mechanistic/fatalistic account of causal necessity, one compatible with the existence of laws of nature but not deterministic in the way this is usually understood.

In this paper, I defend traditional Platonic mathematical realism from its contemporary detractors, arguing that numbers, understood as abstract, non-physical objects of rational intuition, are indispensable for the act of counting.

I argue that, despite claims that might be made to the contrary, no scientific evidence could ever prove that introspection is unreliable, even in principle. This paper was read at the annual POH symposium in Lake Wenatchee in May, 2011.
