Keith Lehrer is the Regent’s Professor emeritus of Philosophy at the University of Arizona with an affiliation with the University of Miami (Florida). In addition to his numerous published articles in areas such as epistemology, free will, rational consensus, and Thomas Reid, Keith has also authored several books including Thomas Reid (1989), Theory of Knowledge (1990), and Self-Trust: A Study of Reason, Knowledge, and Autonomy (1997). Keith also has a research interest in aesthetics, with his most recent book being Art, Self and Knowledge (Oxford University Press, 2011), and can currently be found bridging the gap between theory and practice as an active painter and performance artist (the website for his paintings can be found here). It is truly an honor to have Keith as part of Aesthetics for Birds’ Philosopher-Artist series.
