The Principle of Non-Contradiction’s Incredible Implications

Thomism’s metaphysical first principle of non-contradiction (PNC) reads, “Being cannot both be and not be at the same time and in the same respect.” Its sister first principles are those of identity and excluded middle. Its logical form reads, “The same predicate cannot be affirmed and denied of the same subject.” The metaphysical statement is about being itself (that which in any way has existence), not about propositions about being. There appears little reason to examine... Read More

Robots and the Resurrection

The conversations happening today in the field of artificial intelligence, known as AI, are completely mind-blowing. Aside from AI robots using 3D printing to build bridges in the Netherlands or cars in Los Angeles with digital nervous systems, the crucial topic of discussion is the unknown potentialities which AI technology could precipitate. The central question which belabors not only scientists and engineers but also economists, politicians, and Christians is ultimately: “What... Read More

Was Bertrand Russell Right About Thomas Aquinas?

Bertrand Russell was one of the most prominent philosophers of the 20th century, and an outspoken skeptic. His bestselling book A History of Western Philosophy (which was cited as one of the reasons for his 1950 Nobel Prize in Literature) contains a short chapter in which he examines St Thomas Aquinas’ life and work, concluding with the following, damning remark: There is little of the true philosophic spirit in Aquinas. He does not, like the Platonic Socrates, set out to follow wherever... Read More

How Human Free Will Harmonizes with “Sufficient Reason”

This article’s sole purpose is to defend free will against the claim of those who maintain that free will is metaphysically impossible, because it somehow violates the principles of sufficient reason and causality. Arguments Against the Harmony The most forceful argument against free will’s possibility is the claim that it violates Thomistic metaphysics’ understanding of the principle of sufficient reason. That principle states that every being must have a sufficient reason for... Read More

How We Know the Human Soul is Immortal

In a 2015 video, I facetiously argued that, based on his own philosophical assumptions, Dr. Richard Dawkins does not actually exist. Of course, I firmly believe he does. But, my point was that, given his view of the universe, in which things are merely interacting aggregates of subatomic particles, there is no place for substantial unities above the level of whatever ultimate particles compose the cosmos. A substantial unity is a thing whose entire nature is the same throughout. Every... Read More

The Top 5 Problems with Contemporary Christian Apologetics

I spend a lot of time criticizing contemporary Christian apologetics. Since I am myself a Christian apologist, that might seem a bit strange. But it is, in fact, simply a practical outworking of my commitment to what I call the 50/50 Rule: 50/50 rule: devote as much time to (a) defending the beliefs of your opponents and critiquing your own beliefs as you devote to (b) critiquing the beliefs of your opponents and defending your own beliefs.... Read More

Does Good Conversation Really Require an Open Mind?

Over the years, I have often heard atheists pose the question, “What kind of evidence would it take you to give up your Christian belief?” In many cases, the assumption behind the question seems to be that the Christian should have some clear threshold of evidence in mind. And failure to state what that threshold is would call into question the rationality and intellectual seriousness of the Christian. Atheists aren’t the only ones posing this kind of demand. I recently came across... Read More

Just What Are Men and Women, Anyway?

Sometimes, the most important questions are the basic ones. Back in 2011, I argued that the most important question in the gay-marriage debate was “What is marriage?” The next year, Robert George, Ryan Anderson, and Sherif Girgis published a book exploring just that question: What Is Marriage?: Man and Woman: A Defense. But in the face of contemporary questions of transgenderism and gender identity, it turns out that we need to ask a yet more-basic question: what... Read More

Whatever is Moved is Moved By Another

“Motion is the act of a being in potency insofar as it is in potency.” - Aristotle, Physics Book III, 201a10-11 In his famous First Way of proving God’s existence, St. Thomas Aquinas says, “It is certain, and evident to our senses, that in the world some things are in motion.”1 But, are things really in motion? Most people would think that motion in the world is too obvious to doubt. Yet, some, based on theories of modern physics, claim that physical change in the universe is... Read More
