 D. Gene Witmer

Associate Professor of Philosophy

Ph.D., Rutgers University, 1997


Areas of research:  Metaphysics, philosophy of mind, physicalism, consciousness, a priori knowledge


My areas of research lie in metaphysics and philosophy of mind, often focusing on the doctrine of physicalism. I have worked on such topics as the nature of intrinsic properties, metaphysical grounding, mental causation, functionalism, conceptual analysis, and a priori knowledge. A book defending a kind of a priori physicalism is planned. My interests extend as well to meta-ethics, epistemology, and philosophy of religion.

Spring 2021 Teaching


PHP 5785 Foundations of Analytic Philosophy

"Analytic Philosophy" is the label used for that sort of philosophy that developed in the first half of the 20th Century and became dominant in the English-speaking philosophical world up until the present day. There is little agreement on what the label signifies other than a common philosophical inheritance. That inheritance is precisely what this course covers: a survey of influential work by Frege, Russell, Wittgenstein, Carnap, Quine, and others. We will focus on methodological issues in philosophy and how theories of language, knowledge, and metaphilosophy have shaped the debate over the best way to proceed in addressing philosophical questions. Our goal is in part historical but more importantly philosophical: the hope is to gain a clear understanding of the arguments, theories, and questions that animated this literature and which continue to shape the dominant philosophical tradition today.
