We have a strong intuition that personal identity is a determinate relationship. Parfit famously challenged this intuition. In this paper I explain how narrative identity theories can face that challenge and defend that personal identity is determinate thanks to what I call the social narrativity thesis. This move will raise some concerns regarding the also strong intuition that personal identity is what matters when we care about our future existence. I address this concern to show that narrative identity theories can (...) account for both intuitions at the same time. (shrink)

Marya Schechtman offers a new theory of personal identity, which captures the importance of being able to reidentify people in our daily lives. She sees persons as loci of practical interaction, and defines the unity of such a locus in terms of biological, psychological, and social functions, mediated through social and cultural infrastructure.
