Yale's DeVane Lecture series continues with this fourth session in Purposes of College Education, part of the public lecture course examining why college exists and what it owes students. The lecture takes up Plato's Republic and its central question of why one should be just, using the dialogue to probe what a liberal education is meant to cultivate. Discussion draws on Aristotle and other thinkers from the course's broader reading list, which spans Confucius, John Stuart Mill, Virginia Woolf, Mahatma Gandhi, and Martin Luther King, to connect ancient arguments about justice and character to modern debates over the purpose of higher education. Offered to mark the 325th anniversary of Yale's founding, the course also threads in the university's own founding documents. Running 48 minutes, the lecture treats The Republic as a live philosophical argument rather than a historical artifact, asking what a university is actually for.
