When alumnus Joseph Hattrup (’01) joined the Thomas Aquinas College teaching faculty in 2006, he had already completed his doctoral studies (philosophy, University of St. Thomas), but not his dissertation. He therefore spent most of his vacation and free time over the last several years completing this requirement — a challenging task for a full-time college instructor and father of three young girls. His diligence, however, has paid off, and as a result, he has earned the title of doctor.

Last week, Dr. Hattrup traveled to the Center for Thomistic Studies at the University of Thomas in Houston, Tex. There, he successfully defended his dissertation, “Form and Predicability in Aristotle’s Categories and the Middle Books of the Metaphysics.”

“A widely received view about these works is that they contain doctrines of substance that are contradictory in principle and which therefore show significant changes in Aristotle’s thought,” Dr. Hattrup explains. “I argue that these two doctrines of substance, though different, are compatible with each other and not contradictory in principle. I hope the dissertation will help to demonstrate the unity and consistency of Aristotle’s thought and principles, especially as regards logic and metaphysics.”

The dissertation received unanimous approval of the Examining Board, which subjected Dr. Hattrup to two rounds of vigorous questioning. Dr. Edward Macierowski, an external reader on the committee and a professor of philosophy at Benedictine College, remarked: “Hattrup’s dissertation is not only a recognizable masterwork of a young philosopher, and so a convincing sign that he deserves the doctoral degree, but also the dissertation should be revised and submitted as soon as possible to publication at a major academic press.”

Congratulations, Dr. Hattrup!
