Ad Fontes: Fall 2021 Classes

Updated: Feb 25, 2023

Earlier this year I found myself studying Pope Pius XII‘s 1950 encyclical, “Humani Generis” (On the Human Race). This dazzling document confronts the errors that the human mind can easily fall into, many rooted in either trusting human reason to pass judgment on divine matters, or conversely, taking Scripture as an isolated guide to the exclusion of human reason. The Holy Father remonstrates against a dizzying array of modern heresies and “-isms” that were just beginning to loom at the time of his writing. But I read the encyclical with increasing dismay, because I recognized in his warnings the opinions and mental habits that have become the norm today, even among educated people, even among faithful Catholics.

I was attempting to write a study guide by which teachers and parents could discuss the encyclical with young people. But I kept running into the same problem: we did not listen to Pius XII‘s warning, and now we lack the education and the mental tools even to understand his message.

But there‘s hope. I‘ve seen in my own life the dramatic difference that was made by returning to the sources of our faith. Approaching the “perennial philosophy” as a student rather than a critic has benefitted my life even in practical ways: Aristotle‘s On the Soul illuminates a clearer path to human virtue and fulfillment than all the psychology and self-help books at the bookstore.

Remedying the lacks that modern education has left us with is hard work, but it is possible and so rewarding. That‘s why the Aquinas Institute is still striving to bring the possibility of personal engagement with the sources of our tradition to anyone willing to undertake it, through our online classes. This fall, students in The Philosophy of Man course will have the chance to study Aristotle‘s On the Soul, as well as looking at it in light of the faith, by reading St. Thomas Aquinas‘s commentary on it. Students in The Medieval Vision course will encounter Augustine‘s Confessions, Boethius‘s Consolation of Philosophy, and Dante‘s Divine Comedy.

Our graduate theology courses will address the concerns of “Humani Generis” even more directly. Nothing brings home the continuity of the Church‘s teaching like reading the works of the early Church Fathers. And no work of the human mind is more challenging, more humbling, and more rewarding than delving deeper into the mystery of the Holy Trinity. It‘s never too late to embark on this study, and it‘s never too soon to begin contemplating what will fill our souls for eternity.


Enrollment is currently open for the fall term. All course will be held in the twelve-week session beginning August 2023 and ending November 20th.
