Abstract: This work argues in favor of the relational nature of identity. Some philosophers cast doubts on identityas relation, Armstrong beingone ofthem. This reply to his arguments specifically, and to those who consider identity in terms of co-referentiality, proposes that identity is a relation of reason. An interpretation of identity-statements, compatible with data concerning identity itself, is also presented. For this task both the distinction between specification and description of a domain, and some ideas put forth in Perry 2001 are relevant.
Keywords: relation of reason, John Perry, domain
