Dr. DeWeese's concentration is in metaphysics and epistemology, specifically as related to philosophical theology. He is deeply committed to helping the church articulate and defend the concept of objective truth in an age of postmodernism and growing relativism. With a background in the sciences, he also has a long-standing interest in the relationship of science and theology. Dr. DeWeese brings a strong practical orientation to the classroom, having served as a missionary and over 15 years as a pastor. He is a frequent speaker in churches and college groups. He authored God and the Nature of Time, Philosophy Made Slightly Less Difficult (with J.P. Moreland), and Doing Philosophy as a Christian. He has contributed chapters to several books, and has published articles in journals such as Philosophia Christi and Discipleship Journal.
