Leon Kass

Modern people tend to ignore questions about the nature and purpose of things while learning to control them more efficiently. But as science and technology offer us the ability to fundamentally transform human nature, we can no longer avoid addressing metaphysical questions. The crisis of our time, many thinkers agree, is one concerning the definition of human nature. In “Human Life, Human Dignity,” Leon Kass outlines what is at stake and sets forth a framework for indispensable discussions surrounding biotechnologies. Kass stresses that we must approach the discussion with reverence and awe and that a major component of the discussion should be the notion of human dignity. Kass recommends that we turn first not to the findings of science and technology, but to the canon of “residual wisdom” in the East and West—found in literary, philosophical, and religious traditions—that vividly depicts human nature in its glories and tragedies. 60 minutes.

Leon Kass, physician, biologist, and professor of philosophy at the University of Chicago, discusses his book The Hungry Soul: Eating and the Perfecting of Our Nature, in which he explores how the activity of eating provides clues for understanding human nature and helps guide morality and communal life. Then Brother Peter Reinhart talks about the art of breadmaking as a metaphor for spiritual life. 72 minutes.
