As the President's Council on Bioethics emphasized in a recent report, rapid growth of biotechnologies creates increasingly many possibilities for enhancing human traits. This article addresses the claim that enhancement via biotechnology is inherently problematic for reasons pertaining to our identity. After clarifying the concept of enhancement, and providing a framework for understanding human identity, I examine the relationship between enhancement and identity. Then I investigate two identity-related challenges to biotechnological enhancements: (1) the charge of inauthenticity and (2) the charge (...) of violating inviolable core characteristics. My thesis is that a lucid, plausible understanding of human identity largely neutralizes these charges, liberating our thinking from some seductive yet unsound objections to enhancement via biotechnology.

Transhumanism is a loosely defined movement that has developed gradually over the past two decades. It promotes an interdisciplinary approach to understanding and evaluating the opportunities for enhancing the human condition and the human organism opened up by the advancement of technology. Attention is given to both present technologies, like genetic engineering and information technology, and anticipated future ones, such as molecular nanotechnology and artificial intelligence.

A person can be true to oneself even while transforming and even creating the person one is. One's self is not something merely waiting to be discovered, after all. To some extent, part of the human endeavor is deciding and trying to become who we want to be.

Current and future possibilities for enhancing human physical ability, cognition, mood, and lifespan raise the ethical question of whether we should enhance normal human capacities in these ways. This chapter offers such an account of enhancement. It begins by reviewing a number of suggested accounts of enhancement, and points to their shortcomings. The chapter then identifies two key senses of “enhancement”: functional enhancement, the enhancement of some capacity or power (e.g. vision, intelligence, health) and human enhancement, the enhancement of a (...) human being's life. The latter notion is the notion of enhancement most relevant to ethical debate. The chapter argues that it is best understood in welfarist terms. It illustrates this welfarist approach to enhancement by applying it to the case of cognitive enhancement. Unlike the sociological pragmatic and functional approaches, the welfarist account is inherently normative. It ties enhancement to the value of well‐being. (shrink)
