Keith Lehrer

Keith Lehrer (born January 10, 1936) is the Regent's Professor emeritus of Philosophy at the University of Arizona with an affiliation with the University of Miami in Florida. He previously taught at the University of Rochester.

Lehrer received his Ph.D. in philosophy from Brown University where he studied under Richard Taylor and Roderick Chisholm. His research interests include epistemology, free will, rational consensus, Thomas Reid and, recently, aesthetics.

Lehrer is a former president of the Pacific Division of the American Philosophical Association (APA) and also served as the APA executive director for a number of years.

Lehrer's work, "Why Not Skepticism?" is used in many introductory philosophy courses as a coherent and readable introduction to the subject. He has authored seven books on philosophical subjects, and over 170 scholarly articles. Lehrer is perhaps best known for his defense of the coherence theory of justification in epistemology. He is the originator of the widely discussed TrueTemp example.

Lehrer, and his wife Adrienne Lehrer, are also artists. Their work has been on display at the Vincent Gallery in Coconut Grove, Florida, concurrent with his stay at the University of Miami, where he was a visiting professor.

Lehrer served a visiting professor in the Philosophy Department of Franklin and Marshall College in 2011.
