Dr. Rosario: You are best known for your work on St. Thomas Aquinas. Could you tell us what you find attractive in the thought of this medieval thinker who appears mainly to have been ignored by Descartes, Kant, Hegel, Husserl and Heidegger?I can't vouch for the others, but Heidegger did lecture about Aquinas, and the place of essentia and existentia in the history of ontology.
