Abstract The goal of this chapter is to provide an opinionated overview of the psychologically based account of personal identity and the role of agency within such an account. I describe the essential points of the psychological criterion of personal identity. Then, I discuss how the psychological criterion is related to the Reductionist View of personal identity and whether it is committed to what Derek Parfit names the Extreme Claim. I further discuss how the agency-based views of personal identity can (...) be accommodated within Derek Parfit’s psychologically based view of personal identity. I end the chapter by discussing how an agency-based view, as most notably developed by Christine Korsgaard, could be used to vindicate practical concerns that are traditionally related to personal identity.
