Summary

Prof. Michael Krom argues that just war principles still govern contemporary warfare, especially drone warfare and autonomous weapons, and that moral judgment cannot be replaced by technology or legal convenience.

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.

0:27.6

thinking through or at least kind of mentioning some contemporary, more contemporary

0:32.6

examples largely drawn from the U.S. and thinking about presidential decisions this afternoon,

0:39.4

Father Aquinas is going to get us more specifically to the issue of Truman's decision to drop,

0:45.9

to use the atomic bomb. And so really thinking of a concrete. But I am a philosopher,

0:50.7

and so with philosophers, the rubber almost never hits the road. We're going to come pretty close, but it's always going to be like in the last session,

0:59.0

I hesitant to form a judgment on a particular thing.

1:03.0

When it comes to principles, I'm pretty confident about that,

1:06.0

even though some of these do get a little bit challenging to think about.

1:09.0

So, okay, what we're going to do is

1:11.4

let's jump in and now make sure I get my timer started to this part on your handout,

1:19.9

the just war principles. And there's not universal agreement about which principles there

1:25.2

are. There's definitely some disagreements, even within, you know,

1:28.9

people committed to a Christian and a Catholic analysis. I think this is a very helpful one

1:35.4

from Christopher Toner, who is a professor at, I think, University of St. Thomas in Minnesota.

1:42.3

He doesn't seem to be working much on just war currently, but this is an

1:45.6

article that he wrote that I think does a good job of organizing how do these principles

1:52.6

fit together. So you'll notice on the left is use ad balaam, the principles for being right
