Abstract

In this chapter, I provide a critical exposition of the contemporary bioethics of life extension (LE). First, I provide critical socio-historical contextualization for contemporary bioethics in general by locating it within postmodernity, which discloses crucial implications for what normative claims can possibly be justified within contemporary bioethics and clarifies the typical form that transgression of these limits takes in contemporary bioethics. In the next section, I analyze the structure of the debate over LE into arguments for the necessary desirability (or undesirability) of LE and those for the contingent desirability (or undesirability) of LE, and I provide a survey of the latter. Then, in the next two sections, I critically explicate the main arguments for the necessary desirability and undesirability of LE. I conclude with some final critical remarks on the debate, emphasizing the need for public bioethicists to recognize and be more responsive to the theoretical and empirical pluralism characteristic of the postmodern liberal states in which they typically operate.
