At the Philosophy Department of the University of Dallas, Aquinas’s admonition to “love both: those whose opinion we follow, and those whose opinion we reject” is taken seriously. At U.D., we study and teach the philosophical tradition in its full breadth, affording each thinker the sympathetic hearing which Aquinas considered appropriate in approaching his own sources?whether Christian, Jewish, Islamic, or pagan. Thus, our faculty offer courses that range from the Presocratics, Plato, and Aristotle through medieval and modern thinkers to such influential contemporary philosophers as Wittgenstein, Heidegger, and Foucault. Non-Western traditions such as Oriental thought also find a place in our curriculum. Nevertheless, in our department this diversity does not entail a lack of focus; the “quest for the truth” of which Aquinas speaks is not an empty phrase. We believe that the truth exists, and remain faithful to the Christian heritage as developed in the tradition of the Catholic Church. We want to follow the example of Aquinas in endeavoring to enrich this heritage continuously, and in never ceasing to rethink it in the light of new philosophical challenges.
