This Festschrift in honour of Jean Porter, whose research over her career has focused on the most important topics in moral theology, including action theory, virtue, natural law and justice.

Crossing disciplinary boundaries, from theology to philosophy to law, a group of leading Catholic and Protestant scholars celebrate the life work of Jean Porter. The contributors engage a wide range of topics in moral thought – from the very foundations of morality, to the technical nuances of human action and formation, to applications to a variety of social matters.

A diverse range of contributions, they are all bound by an engagement with Jean Porter's own interests and scholarship. They honour her in the way she would most appreciate: offering the highest level scholarship on topics germane to moral theology.

William C. Mattison III is Wilsey Family Professor, and the Faculty Director of the Moreau Program, at the University of Notre Dame, USA.

Joseph E. Capizzi is Dean and Ordinary Professor of Moral Theology at the Catholic University of America, USA.
