Biotechnology (BT) offers exciting and promising prospects for healing the sick and relieving the suffering. But because of their impressive powers to alter the workings of body and mind, the "dual uses" of the same technologies make them attractive also to people who are not sick but who would use them to look younger, perform better, feel happier, or become more "perfect." These applications of BT present us with difficult challenges. This report considers such possible "beyond therapy" uses and explores both their scientific basis and the ethical and social issues they will raise. In enjoying the benefits of BT, we will need to hold fast to an account of the human being, seen not in material or mechanistic or med. terms, but in psychic and moral and spiritual ones.
