The bioconservatives are in retreat. Harris has now set the agenda for the future of humankind. This will be the locus classicus for the enhancement debate.

John Harris can be depended on to sharply challenge conventional thinking in bioethics, especially when that thinking takes a conservative cast. He does not disappoint here. Harris shows how deep-seated a part of human history enhancement is and how weak most objections to it are; indeed, he makes a persuasive case that it is not only generally morally permissible, but often morally required.
