Cooperation in evil and Thomas Aquinas’s understanding of justice


We’re presenting a short series of abstracts of the work-in-progress our scholars presented and discussed at their June 2017 Working Group Meeting.

Kevin Flannery, S.J., is Professor of the History of Ancient Philosophy, Pontifical Gregorian University in Rome.

As the participants in our seminar may recall, I am writing a book on the ethics of cooperation in evil. At an earlier meeting of the seminar, I discussed some of the problems contained in the treatment of such cooperation as found in the manuals of Catholic moral theology of the 18th, 19th, and early 20th centuries. On that occasion, I expressed agreement with Elizabeth Anscombe’s criticism of that tradition as vitiated by what she calls “Cartesian psychology,” according to which “an intention was an interior act of the mind which could be produced at will.” I also expressed then a preference for an analysis in terms rather of Thomas’s Aquinas’s understanding of the moral virtue of justice. In my presentation, I would like describe how I understand this virtue and how it helps us to determine when a person’s—or indeed an institution’s or a government’s—cooperation is immoral. This will involve an explanation of how justice, according to Thomas, stands in relation to the other virtues, especially prudence. It will also involve an account of how justice, which is a virtue of the will, bears upon the consciences of individuals.
