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

Speaking the Truth in the Beauty of Love: A Guide to Better Online Discussion

EDITOR'S NOTE: This talk was delivered by Dr. Bryan Cross, a Strange Notions contributor, at Franciscan University on July 29, 2017.

We're sharing it given our special commitment here to "speaking the truth in love," to rational, charitable discussion. Enjoy!     I. Introduction   A number of years ago, before... 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

Why an Infinite Regress Among Proper Causes is Metaphysically Impossible

Presuppositions, definitions, and purpose: This article presupposes the metaphysical first principles of non-contradiction, sufficient reason, and causality, which I defended earlier in a Strange Notions article. By the principle of sufficient reason, I mean that every being has a sufficient reason for its being or becoming. This principle is recognized by virtually all mankind as essential to reality’s intelligibility. By causality, I mean that every effect (a being whose sufficient... Read More

“Brute Facts” vs. “Sufficient Reasons”

The metaphysical principle that every thing must have a sufficient reason for its being or coming-to-be is challenged by those who claim that some “brute facts” exist, that is, things for which there are simply no reasons at all. The opponents of sufficient reason’s universality claim that science works quite well by finding reasons for many things, even though we allow that one thing or some things might turn out just to be “brute facts,” that is, things without a reason. But... Read More

Why Modern Physics Does Not Refute Thomistic Philosophy

Today some claim that modern physics evinces that Aristotelian-Thomist philosophy is an archaic myth that has outlived its credibility. They say things like, “If Thomist metaphysics contradicts modern physics, then Thomism is false.” They make claims against Thomism, citing modern physical theories like quantum mechanics and relativity. We are told counterintuitive things, such as that (1) whole universes can pop into existence from nothing according to quantum mechanics, (2) effects... Read More

“Optimistic Nihilism” and Whistling Past God’s Graveyard

The colorful six-minute animation from the YouTube channel Kurzgesagt recently raked in millions of views with a brief history of...well, everything. The narrator offers a naturalistic view of the entire universe, but carries it to nihilistic conclusions. .embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%;... Read More

What Is the True Understanding of Causality?

The classical proofs for God’s existence, particularly St. Thomas Aquinas’ Five Ways, employ the notion of causality – both efficient and final. In that context, many misunderstandings arise concerning the true metaphysical meaning of the principle of causality. This article will assume the validity of the metaphysical first principles of non-contradiction and sufficient reason, which were established as true in my previous Strange Notions article on the first principles – and... Read More

Are Metaphysical First Principles Universally True?

Today, certain lines of attack against classical proofs for God’s existence, such as St. Thomas Aquinas’ Five Ways, seek to undermine foundational metaphysical first principles such as causality, sufficient reason, or even non-contradiction.1 Such attacks employ, for example, claims that (1) David Hume’s critique of causality is definitive, (2) the existence of the cosmos is simply a “brute fact,” needing no explanation, and (3) modern physics shows that the principle of non-contradiction... Read More
