Dear Colleague:
Resources for Modern Aristotelian Philosophy has a new posting: "Why Change Needs an Efficient Cause: How Aristotle Could Refute Hume".
This is the first chapter of a projected e-book, A RE-introduction to Philosophy: Why Post-Fregean Methods Have Not Reduced Philosophic Disagreement and Paradox. To see the connection between the topics of the book and the first chapter, please read the 4-page "Introduction" to the book, also just posted.

Abstract
Hume said that the otherness of cause and effect makes it epistemically necessary that dependence on an efficient cause cannot be epistemically necessary; for that otherness prevents the negation of dependence on a cause from being contradictory. My critique of Hume is distinguished from others by starting from the grasp of a kind of dependence other than on an agent. A motion newly occurring to an already existing subject is caused by—is nonidentical with and cannot exist without—its subject, though not by efficient causality. Both philosophic tradition and ordinary language use “cause” in a sense broad enough to cover the subject and the agent of change. Seeing that a change occurring to what is other than itself needs a cause of some kind refutes Hume’s argument from otherness. (To my knowledge, this is the only reply to Hume based on Aquinas’ (De Pot., 5.1) insight, which I was pleased to learn about later, that “The necessity of an effect’s dependence on its cause is obvious in the case of . . . ‘material’ causes.”) The question is no longer whether a change has any cause but whether a previously unchanging subject can be a change’s sole cause. I show that, if the sole cause is supposed to be the subject as only potentially changing, the change is caused and has no cause. (I was pleased to learn later that Yves Simon (1969, 131-134) had said “The need for the efficient cause arises when the mind recognizes the insufficiency of explanation by the material cause. . . . If the only origin of being in act is being in potentiality, the origin of that addition of reality which distinguishes being in act from being in potentiality is nothing.” But Simon did not use this to explain Hume’s error.) And if the sole cause is supposed to be the subject as actually changing, the change unavoidably becomes a cause of itself. Even Hume (Treatise, 1, 3, 3) saw that something’s having nothing for a cause or being a cause of itself is contradictory, if dependence on some cause is established first.
