He taught at St. John's College (Annapolis) and Georgetown University before returning to the University of Chicago, where for thirty-four years he was an award-winning teacher deeply involved in undergraduate education and committed to the "big questions" and the study of classic texts.

Kass); Life, Liberty, and the Defense of Dignity: The Challenge for Bioethics; The Beginning of Wisdom: Reading Genesis; and What So Proudly We Hail: The American Soul in Story, Speech, and Song (with Amy A. Kass and Diana Schaub). Dr. Kass served on the National Council on the Humanities and as chairman of the President's Council on Bioethics. He was an inaugural recipient of the Bradley Prize in 2003. In 2009 he delivered the Jefferson Lecture in the Humanities.
