The Personal Identity Dilemma for Transhumanism

Transhumanists claim that futuristic technologies will permit you to live indefinitely as a nonbiological ‘posthuman’ with a radically improved quality of life. Philosophers have pointed out that whether some radically enhanced posthuman is really you depends on perplexing issues about the nature of personal identity. I present an especially pressing version of the personal-identity challenge to transhumanism, based on the ideas of Derek Parfit. Parfit distinguishes two main views of personal identity, an intuitive, nonreductive view and a revisionary, reductive view. I argue that the standard rationale for wanting to become a posthuman makes sense only if the intuitive view is correct, but that the standard rationale for thinking that it is possible to become a posthuman makes sense only if the revisionary view is correct. Following this, I explain why the obvious responses are unsatisfactory or imply the need to rethink transhumanism in ways that make it much less radical and less appealing.
