About the Speakers:

Michael Krom started reading Aquinas’s Summa Theologiae shortly after his conversion at the end of college. Upon learning about Flannery O’Connor’s “hillbilly Thomist” habit of reading Aquinas every night, he started studying two articles a day and completed the Summa while in graduate school at Emory University. As a professor at Saint Vincent College, he saw the urgent need for collegians and seminarians to receive a solid foundation in Aquinas’s philosophical theology. In 2020, he published Justice and Charity:  An Introduction to Aquinas’s Moral, Economic, and Political Thought (Baker Academic Press), and teaches a Thomistic philosophy course each fall. In addition to continuing work on the moral, economic, and political topics covered in the book, his current research is on the influence of monastic spirituality on Aquinas; he is working on a monograph tentatively entitled Aquinas Among the Benedictines.

Keywords: AI, Autonomous Weapons, Common Good, Conscience, Discrimination, Drone Warfare, Human Judgment, Just War Theory, Proportionality, Prudence

Prof. Michael Krom argues that just war theory remains morally necessary today because war must be judged by justice, right intention, and the common good rather than by realpolitik, legal minimalism, or national self-interest.

Prof. Michael Dauphinais contends that modern Christians, formed by empiricism, individualism, and a this‑worldly hope that easily turns to despair, especially need the Eucharist because it is the concrete, sacramental way Christ draws us into the Trinitarian communion for which we were created, making his paschal mystery present and reproducing his own filial relation to the Father in us.
