Denis Sullivan has been a member of the Philosophy Department since 1969.  During that time, Dr. Sullivan has also served for one semester as a visiting professor at Leuven University in Belgium and for four semesters as the director of the St. John’s foreign studies program in Budapest Hungary.  He has been a member of the C. S. Peirce Society, the American Philosophical Association, and the American Catholic Philosophical Association.

After doing some initial work on the philosophy of C. S. Peirce, Dr. Sullivan went on to use the resources provided by the analytic tradition to deal with issues especially in ethics and the philosophy of mind.  In ethics, his main interest has been in trying to argue that, contrary to what is assumed among many contemporary philosophers, affirmative morals propositions can be true in the same robust sense in which scientific propositions can be true.  In the philosophy of mind, his interest has been in exploring the relationship between scientific accounts of human behavior and the traditional belief that human beings are free.
