Dr. Poston is the inaugural Director of the McCollough Institute for Pre-Medical Education. His research focuses on questions about rationality and inference. He teaches inductive logic and medical reasoning. He follows Sellars’s synoptic conception of philosophy that “The aim of philosophy, abstractly formulated, is to understand how things in the broadest possible sense of the term hang together in the broadest possible sense of the term.” He has written on a variety of topics including medical reasoning, immigration, social evil, practical knowledge, religious conscience, and theistic arguments.
