Extending a Life with Meaning

Abstract

This essay questions Callahan’s criticism of people’s aspiration to extend their life. It argues that ideas about life are subject to historical variations and the question at issue is whether society can give meaning to aging. It also questions the claim that the radical extension of human life will jeopardize the welfare of future generations. It suggests that the application of the precautionary principle to the question of aging avoid facing up to question how society should value the old.
