The fork here involves a dialectic distinction between two different kind of identity: objective identity, as something which derives from outside of the self, and subjective identity, as something which is self-generated. I'm not sure that this distinction can be drawn quite so sharply. An authentic identity has multiple sources, including whatever is given, in the form of genetics, early socialization, blood relationships, and that spark of Divine genius that kindles the soul at the moment of conception; but also including whatever is chosen, the way that a person lives and understands him or herself. As David Foster Wallace puts it, “the horrific struggle to establish a human self results in a self whose humanity is inseperable from that horrific struggle.” Our true identities are not deducable a priori. They are the result of a creative co-operation between God and the self, they do not really exist until the moment of death when the work is complete. Hence the image of the white stone in the Book of Revelations which contains the person's true name: the word by which the indiviual is incarnated absolutely, and which could not come to be except as a product of the journey through the vale of tears.
