Authenticity has been recognized as a central concept in the ethics of human enhancement. In the last decade, a plethora of novel distinctions, specifications, and definitions of authenticity have been added to the debate. This chapter takes a step back and maps the different accounts of authenticity to provide a nuanced taxonomy of authenticity and reveal the emerging underlying structures of this concept. I identify three kinds of conditions for authentic creation and change of the true self (coherence, endorsement, and (...) relations) as well as ways how the true self should be expressed (in one’s self-conception, self-presentation, and one’s body, emotions, and actions). Based on this analysis, I discuss the hopes and concerns human enhancement raises for authenticity. Enhancement technologies do not threaten or foster authenticity across the board but affect different dimensions of authenticity individually. Finally, I turn to the value of authenticity and argue that the debate on authenticity in the ethics of human enhancement would profit from a more extended discussion on the comparative value of the individual dimensions of authenticity.

For nearly two decades, ethicists have expressed concerns that the further development and use of memory modification technologies (MMTs)—techniques allowing to intentionally and selectively alter memories—may threaten the very foundations of who we are, our personal identity, and thus pose a threat to our well-being, or even undermine our “humaneness.” This paper examines the potential ramifications of memory-modifying interventions such as changing the valence of targeted memories and selective deactivation of a particular memory as these interventions appear to be at (...) the same time potentially both most promising clinically as well as menacing to identity. However, unlike previous works discussing the potential consequences of MMTs, this article analyzes them in the context of the narrative relational approach to personal identity and potential issues related to autonomy. I argue that such a perspective brings to light the ethical aspects and moral issues arising from the use of MMTs that have been hidden from previously adopted approaches. In particular, this perspective demonstrates how important the social context in which an individual lives is for the ethical evaluation of a given memory-modifying intervention. I conclude by suggesting that undertaking memory modifications without taking into account the social dimension of a person’s life creates the risk that she will not be able to meet one of the basic human needs—the autonomous construction and maintenance of personal identity. Based on this conclusion, I offer some reflections on the permissibility and advisability of MMTs and what these considerations suggest for the future. (shrink)

Do neuromodulation technologies change patients’ personal identities? Haeusermann et al. claim that there is not enough evidence to support this worry. In their study, participants, following a res...
