[email protected] ORIGINAL SCIENTIFIC ARTICLE / RECEIVED: 270114 ACCEPTED: 170614 ABSTRACT: In this paper I defend the idea that we need a metaphysical theory to justify identity-related practical concerns, such as self-concern. I outline D. Parfit’s theory, in which the concerns receive a metaphysical justification. Then, I focus on two ob- jections: C. Korsgaard’s claim that the concerns are justified by the unity of agency, and M. Johnston’s contention that the concerns are prima facie justified independ- ently of a metaphysical theory. I argue that even if these theories have a point, they do not cover a range of situations in which justification may be sought. It is in these situations that a metaphysical theory may find its place. KEYWORDS: Justification, metaphysics, personal identity, practical concerns. Introduction There are at least two major trends that can be traced in the metaphysics of personal identity. One trend seeks to develop a theory of personal identity to cohere with the broader picture of the identity and persistence of spatio- temporal objects. The other attempts to develop a theory of personal identity to justify some of the practical concerns and attitudes that have tradition- ally been taken to presuppose the concept of personal identity, such as self- concern, responsibility, compensation, blame, among others.
