Leon Kass at St. John's

A friend and former student sent me the link to this commencement address, by Leon Kass, delivered at St. John's College.  It's wonderful.  Here's a bit:

The greatest moral challenges headed our way do not in fact come from hate-filled fanatics threatening death and destruction. They come rather from well meaning scientists and technologists offering life, pleasure, and enhancement. They are the by-products of modernity’s noble and humanitarian quest to conquer nature for the relief of man’s estate. They are, in a word, the challenges of bioethics, challenges to our humanity arising from burgeoning new technological powers to intervene in the bodies and minds of human beings.
