Just working through Elaine Graham’s paper Bioethics after Posthumanism: Natural Law, Communicative Action and the Problem of Self-Design for a second time. Some good, thought provoking material there. For example,

I think this gets forgotten in all the heated discussions. That some who are vehemently anti-biotechnology, especially in focusing on defending the sanctity of the (abstract) individual, don’t see that technological practices they do approve of may be discriminating against whole communities already in existence. That those people’s human dignity and value as persons is being denied.
