Leon Kass — American Educator born on February 12, 1939,

Leon Richard Kass is an American physician, scientist, educator, and public intellectual, best known as proponent of liberal education via the "Great Books," as an opponent of human cloning, life extension and euthanasia, as a critic of certain areas of technological progress and embryo research, and for his controversial tenure as chairman of the President's Council on Bioethics from 2001 to 2005. Although Kass is often referred to as a bioethicist, he eschews the term and refers to himself as "an old-fashioned humanist. A humanist is concerned broadly with all aspects of human life, not just the ethical.".. (wikipedia)

Cloning represents a very clear, powerful, and immediate example in which we are in danger of turning procreation into manufacture.
Technological innovation is indeed important to economic growth and the enhancement of human possibilities.
In cloning, in contrast, reproduction is asexual - the cloned child is the product not of two but of one.
If you have easy self-contentment, you might have a very, very cheap source of happiness.
