  • The metaphysics of gender

    I recently listened to this talk by John Finley titled The Metaphysics of Gender: A Thomistic Approach. Below are my notes of this. I skip the introductory remarks and follow the four-section division of the talk. Note that by “gender” here we do not mean the psychological or social construct introduced by modern feminists. Rather, by →

  • Common goods

    I had originally intended to tie up the thoughts begun in previous posts on natural and moral goodness, substantial activities, basic goods, and virtual existence, but it has since occurred to me that this would be too ambitious for a single blog post. So, I’ll attempt to approach the topic in installments as I find the time. Those →

  • Contrastive probabilistic explanation

    I want to propose something I’m not totally convinced is correct, but that I think is worth considering. In general we have the question about contrastive indeterministic explanation: an antecedent A can give rise to two different consequences B and C, it actually gives rise to B, and we want to know why it gave →

  • Uninstantiatables in Aristotelian Mathematics

    Any successful Aristotelian foundations of mathematics needs to account for mathematical objects that are uninstantiated and even uninstantiatable. Examples include (1) positive whole (or “natural”) numbers larger than the number of objects in reality, (2) negative numbers, and (3) infinities. Uninstantiated natural numbers As the Aristotelian sees things, we abstract quantity and structure from reality, →

  • Smith’s epistemological argument for hylomorphism

    The following quote comes from Wolfgang Smith’s The Quantum Enigma: As Aristotle pointed out long ago, the act of knowing consists in a certain union of the intellect with its object. But how can the intellect be joined to the external thing? Such a union, clearly, can only be conceived in terms of a third →

  • How Aristotle starts the Nicomachean Ethics

    In the opening passage of the Nicomachean Ethics Aristotle seeks to pick out the specific subject of his study for the remainder of the book. His discussion is often misunderstood, but a good understanding of it will serve us well in understanding the study of ethics. We will consider the passage bit by bit with →

  • From morality to nature and back again

    Below is a talk I recently gave at a local apologetics meet-up. The goal was to introduce and partially defend natural law theory to a group of fellow-Protestants who, as far as I was aware, had not engaged extensively with natural law theory before. The talk was recorded in various parts, with video coming in the second part. →

  • That orders regulate

    ,

    In Summa Theologica II-I Q87 A1 corp. Aquinas says the following: Now it is evident that all things contained in an order, are, in a manner, one, in relation to the principle of that order. Consequently, whatever rises up against an order, is put down by that order or by the principle thereof. And because →

  • Lonergan on Aquinas on Causation

    Below is an excerpt from Bernard Lonergan’s incredible book Grace and Freedom, discussing Thomas Aquinas’s views on causation and how they relate to Aristotle’s views on the topic. Except for the term “actio” I’ve replaced Latin phrases with their English translations in square brackets. Causation is the common feature of both operation and cooperation; its →

  • On the transitivity of strict preference

    The notion of comparing alternatives often comes up in philosophy, particularly when discussing practical reason. There are various names for this (we can talk about the reasons for choosing A over B, or how A is better than B, or how A is more desirable to B, or how A is preferred to B) but →
