Lear earned his B.A. (cum laude) in History at Yale in 1970 and his B.A. in Philosophy at Cambridge in 1973. He then received his Ph.D. in philosophy at Rockefeller University with a dissertation on Aristotle's logic directed by Saul Kripke. He also trained at the Western New England Institute for Psychoanalysis in 1995. He subsequently won the Gradiva Award from the National Association for Psychoanalysis three times for work that advances psychoanalysis.
Before moving to Chicago permanently in 1996, Lear taught philosophy at Cambridge University (1979-1985), where he was a Fellow and the Director of Studies in Philosophy of Clare College. He also taught philosophy at Yale University and was Chair of the Department of Philosophy (1978–79, 1985-1996). He is a member of the International Psychoanalytical Association. In 2009, he received the Mellon Distinguished Achievement Award in the Humanities.[2]
During his time as the Roman Family Director of the Neubauer Collegium for Culture and Society was able to work with the Apsáalooke Nation and the Field Museum of Natural History to sponsor the exhibit Apsáalooke Women and Warriors.[3]
Lear's early work focused on formal logic and ancient Greek philosophy. Much of his work involves the intersection of psychoanalysis and philosophy. In addition to work involving Sigmund Freud, he has also written widely on Aristotle, Plato, Immanuel Kant, Søren Kierkegaard and Ludwig Wittgenstein, focusing on ideas of the human psyche. This most recent work explores the ethical task of managing to live with the fears and anxieties of world-catastrophe.
