Sidney Morgenbesser

Sidney Morgenbesser (September 22, 1921 – August 1, 2004) was a Columbia University philosopher. Born in New York City, he undertook philosophical study at the City College of New York and rabbinical study at the Jewish Theological Seminary of America, then pursued graduate study in philosophy at the University of Pennsylvania, where he wrote his Ph.D. thesis under the direction of Nelson Goodman. Morgenbesser returned to Columbia to teach in 1953 and, in 1975, was named the John Dewey Professor of Philosophy there. Morgenbesser was known particularly for his sharp witticisms and humor, which often penetrated to the heart of the philosophical issue at hand. He published little, and established no school, but was revered for his extraordinary intelligence and moral seriousness. He was a famously influential teacher; his former students include Jerry Fodor, Raymond Geuss, Robert Nozick, and Derek Parfit.

Morgenbesser's areas of expertise included the philosophy of social science, political philosophy, epistemology, and the history of American Pragmatism. He founded the Society for Philosophy and Public Affairs along with G.A. Cohen, Thomas Nagel and others.
