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. In this conversation, Kass recounts how he turned from the study of medicine to an examination of the moral questions and problems that modern science and technology pose for human life. Kass suggests that science, for all of the benefits it has brought to us, may not offer an adequate account of life as we experience it. 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.
