This is the second volume of Maynooth Aquinas Lectures. The annual series was founded by the late Professor James McEvoy in 1995. Its aim is to examine the thoughts of St. Thomas Aquinas and his legacy with a view to exploring new aspects of his philosophical and theological writings, and to foster the interrelationship between the sapiential tradition and contemporary concerns. The present volume contains articles by established experts in the field, as well as by some young scholars. The papers consider the Angelic Doctor as a teacher and examine this prolific scholar’s thought on a wide range of topics: the Eucharist, the problem of suffering, the meaning of being, Thomistic realism, Aquinas’ lost second Sentences commentary, virtue and the Beatitudes, and the four cardinal virtues as an ideal ethical basis for the practitioner-patient interaction in all its dimensions. The book considers such questions as whether God thinks and if we are justified in taking it for granted that Thomistic theology is superior to the theology of the Book of sentences. It also examines Aquinas’ particular contribution to the Latin reception of Dionysian mystical thought and draws to a close with Heidegger’s thoughts on Aquinas and God.
