“ According to Melanie Klein, we develop moral responses in reaction to questions of survivability. My wager is that Klein is right about that, even as she thwarts her own insight by insisting that it is the ego's survivability that is finally at issue. Why the ego? After all, if my survivability depends on a relation to others, to a you or a set of yous without whom I cannot exist, then my existence is not mine alone, but is to be found outside myself, in this set of relations that precede and exceed the boundaries of who I am. If I have a boundary at all, or if a boundary can be said to belong to me, it is only because I have become separated from others, and it is only on condition of this separation that I can relate to them at all. So the boundary is a function of the relation, a brokering of difference, a negotiation in which I am bound to you in my separateness. If I seek to preserve your life, it is not only because I seek to preserve my own, but because who I am is nothing without your life, and life itself has to be rethought as this complex, passionate, antagonistic, and necessary set of relations to others. I may lose this you and any number of particular others, and I may well survive those losses. But that can happen only if I do not lose the possibility of any you at all. If I survive, it is only because my life is nothing without the life that exceeds me, that refers to some indexical you, without whom I cannot be. ”
