Is God “Pure Act”?

According to classical theism (as exemplified by Aquinas), God is “Pure Act”. What does that mean, you ask? Good question. The idea goes back to Aristotle, but we’ll pick it up with Aquinas. Very early on in the Summa Theologiae Aquinas says the following: For motion [motus, i.e., change] is nothing else than the reduction… Read More »

Perfect Love and the Trinity

There’s an interesting discussion on the Christian doctrine of the Trinity going on at Prosblogion. I figure this is as good a time as any to dust off some speculations of my own on the subject. The doctrine of the Trinity, a cornerstone of Christian orthodoxy, may be summed up in the following two propositions:… Read More »

Raving Thomists

I just woke up from a dream in which I was being chased by a very persistent Thomist who wanted to sift my soul through some sort of metaphysical meat-grinder. Not wanting to find out what that would do to me, I escaped to Paradise, where I learned that Father Abraham now relaxes in a… Read More »

The Paradoxes of Material Disjunction

In a previous post, I commented that truth-functional interpretations of conditionals are bothered by what are known as the “paradoxes of material implication”. The problem arises because it is easy to form conditionals that, on the truth-functional interpretation, come out as true when, intuitively, they aren’t true. What I want to point out now is… Read More »

Are Disjunctions Truth-Functional?

A ‘disjunction’ is an either-or proposition. It has the form “Either A or B or …”, where the terms A, B, etc. are called ‘disjuncts’. The simplest type of disjunction has only two disjuncts: Either A or B. Taking the “or” here in the usual inclusive sense, what this says is simply “Here are the… Read More »

The Dialectic of Liberty and Security

I was reminded today of some insightful thoughts from the Maverick Philosopher: Liberty and security stand in a dialectical relation to each other in that (i) each requires the other to be what it is, and yet (ii) each is opposed to the other. … Ad (i). Liberty worth having is liberty capable of being… Read More »

In Defense of Prior’s ‘Peircean’ Tense Logic

I just finished a paper defending what philosopher Arthur Prior called the “Peircean” system of tense logic over against the rival “Ockhamist” system. You can download the paper here (100kB, PDF). I’ll be reading this paper at the group meeting of the Philosophy of Time Society at the Pacific APA conference in March. For some… Read More »

What’s Wrong with Hume’s Fork

In Section 4 of his Enquiry Concerning Human Understanding, David Hume makes a famous distinction between “matters of fact” and “relations of ideas” All the objects of human reason or enquiry fall naturally into two kinds, namely relations of ideas and matters of fact. The first kind include geometry, algebra, and arithmetic, and indeed every… Read More »

Limits vs. Limit Cases

I just finished reading Barry Miller’s The Fullness of Being, a very stimulating book. Miller argues against Russell, Frege, Quine, et al. that existence can be predicated of individuals and develops an interesting metaphysical account of the relation between an individual and its existence. Anyway, at one point Miller argues for a sharp distinction between… Read More »

Is the Possible Necessarily General?

I’m not going to try to settle this question right now, but merely to point out some of the consequences of answering it with either a ‘yes’ or a ‘no’. Charles Peirce once said “The possible is necessarily general; and no amount of general specification can reduce a general class of possibilities to an individual… Read More »
