Robert Hahn (professor)

Robert Hahn (born in New York City, 25 August 1952) is an American philosopher and he is a Professor of Philosophy at Southern Illinois University Carbondale, since 2002. Hahn teaches interests and specialties which include ancient Greek philosophy, history of philosophy, science (astronomy and mathematics - especially geometry), Kant, modern philosophy, ethics, and logic. His research focuses on ancient Egyptian and Greek architecture, building technology, ancient geometry, and metaphysics - connecting the origins of Greek philosophy from the historical, cultural, and technological contexts to the early Greek philosophers.

Education

Hahn was named the Archibald Scholar and graduated as Valedictorian from the College of Liberal Arts at Union College with his B.A. in Philosophy in 1973. He was elected into Phi Beta Kappa in 1972. During his undergraduate years, he also studied Sanskrit at the University of Chicago (Summer, 1972). Hahn began his first-year graduate studies at the University of California, Berkeley, transferring the following year to Yale University where he went on to earn three degrees: M.A. in Philosophy (1975), M.Phil. in Philosophy (1975), and Ph.D. in Philosophy (1976, when he was 23 years old). Hahn won Yale's Mary Cady Tew Prize for the Outstanding Graduate Student in Philosophy (1975) and the Jacob Cooper Prize in Greek Philosophy (1975) for an earlier draft of his dissertation. Hahn’s dissertation was entitled “Did Plato ‘Schematize’ the Forms: Structure, Value, and Time, in the Later Dialectical Dialogues,” directed by Karsten Harries and joined in committee by Robert S. Brumbaugh and Heinrich von Staden.

Early Academic Career

After graduating from Yale, in the fall of 1976, Hahn worked with Gregory Vlastos (who had recently left Princeton to become the Mills Professor of Philosophy) at the University of California at Berkeley, followed by an appointment back at Yale in the Spring of 1977 as a Lecturer in Philosophy. Subsequently, in 1977, Hahn was appointed to his first tenure-track position at the Arlington branch of the University of Texas, but left the next year for a 3-year appointment (1978 - 1981) jointly at Brandeis University (in the Department of Philosophy and the History of Ideas) and Harvard University (Continuing Education). At Brandeis, Hahn created the Boston Area Colloquium for Ancient Philosophy which is still functioning after more than forty years. Hahn was Visiting Professor of Philosophy at the American College of Greece (Deree College) from January to August 1980. In 1981, Hahn was an Assistant Professor of Philosophy at Denison University, and in 1982, joined the faculty of Southern Illinois University at Carbondale as an Assistant Professor of Philosophy. He became an Associate Professor in 1988. Hahn was awarded both the Outstanding Teacher of the College and the Outstanding Educator of the University in 1993. He was promoted to full professor in 2001.
