"In childhood we see the struggle for self-esteem at its least disguised. The child is unashamed about what he needs and wants most. His whole organism shouts the claims of his natural narcissism. And this claim can make childhood hellish for the adults concerned, especially when there are several children competing at once for the prerogatives of limitless self-extension, what we might call “cosmic significance.” The term is not meant to be taken lightly, because this is where our discussion is leading. We like to speak casually about “sibling rivalry,” as though it were some kind of byproduct of growing up, a bit of competitiveness and selfishness of children who have been spoiled, who haven’t yet grown into a generous social nature. But it is too all-absorbing and relentless to be an aberration, it expresses the heart of the creature: the desire to stand out, to be the one in creation. When you combine natural narcissism with the basic need for self-esteem, you create a creature who has to feel himself an object of primary value: first in the universe, representing in himself all of life. This is the reason for the daily and usually excruciating struggle with siblings: the child cannot allow himself to be second-best or devalued, much less left out. “You gave him the biggest piece of candy!” “You gave him more juice!” “Here’s a little more, then.” “Now she’s got more juice than me!” “You let her light the fire in the fireplace and not me.” “Okay, you light a piece of paper.” “But this piece of paper is smaller than the one she lit.” And so on and on. An animal who gets his feeling of worth symbolically has to minutely compare himself to those around him, to make sure he doesn’t come off second-best. Sibling rivalry is a critical problem that reflects the basic human condition: it is not that children are vicious, selfish, or domineering. It is that they so openly express man’s tragic destiny: he must desperately justify himself as an object of primary value in the universe; he must stand out, be a hero, make the biggest possible contribution to world life, show that he counts more than anything or anyone else."
