Abstract

HILLER, Fernando Rudy. Are Morality and Personal Identity Products of Self-Constitution? Two Objections to Korsgaard's Self-Constitution. Diánoia [online]. 2013, vol.58, n.70, pp.191-213. ISSN 0185-2450.

In Self-Constitution. Agency, Identity, and Integrity (2009), Christine Korsgaard argues that the categorical imperative rules human action because it is the sole principle that allows us to reach the complete psychic unity that, Korsgaard thinks, is an essential prerequisite for effective action. Reaching this unity -which consists in making cohere diverging impulses for action- is for human agents a constant activity called "self-constitution." According to Korsgaard, this activity is the source of normativity, of human practical identities and even of personal identity. After explaining the main ideas of the book, I present two objections. First, I criticize the linkage of the categorical imperative to successful self-constitution, for not every failure of the latter counts as a moral failure. Second, I argue that the thesis that personal identity is a product of self-constitution is problematic and that it betrays a confusion between practical identity and personal identity.
