Leon R. Kass, M.D., is Professor Emeritus at the University of Chicago, the Madden-Jewett Chair at the American Enterprise Institute, and one of the nation’s most distinguished bioethicists.

Kristol and Kass also discuss the Bible as a source of wisdom and the similarities and differences between the Biblical view of man and the one found in Greek philosophy.
