Summary of scientific research
My interest from the beginning has been in the nature of being. The approach (following my teacher, Etienne Gilson) has been historical, focusing primarily on St. Thomas. I wrote a doctoral dissertation in Toronto on the doctrine of being of Johannes Capreolus. Subsequent studies have concentrated on the ineluctable contribution of form and essence for an adequate conception of being. I have also stressed the validity of Thomas’s assessment of Aristotle as a source of metaphysical insight, including Thomas’s attribution to Aristotle of a doctrine of creation; rejection of this view stems from a conception of being which remains somewhat on the level of physics. However, metaphysical interests lead to studies concerning the nature of knowledge and the foundations of morals. I have also been active in these areas.
