New medical technologies promise to allow us to transform our core characteristics. Some see these technologies as filled with promise. Others see them as filled with existential risk. David DeGrazia argues that personal identity concerns raised by opponents to enhancement technology fail to impugn attempts by autonomous agents to bring about enhancements with which they autonomously identify. In advancing this argument DeGrazia evaluates five supposedly inviolable core narrative characteristics, concluding that none of these characteristics are in fact inviolable so long (...) as the individual contemplating transformation autonomously identifies with the change they decide to make. Employing insights gleaned from LA Paul’s recent work on the subject of transformative experiences I will argue that at least for some transformations, the prospects for autonomous identification are slim at best. The upshot will be that many of the core narrative traits discussed by DeGrazia will be inviolable in practice, if not in principle. (shrink)
