One of the key concepts for understanding man’s urge to heroism is the idea of narcissism. As Erich Fromm has so well reminded us, this idea is one of Freud’s great and lasting contributions. Freud discovered that each of us repeats the tragedy of the mythical Greek Narcissus: we are hopelessly absorbed with ourselves. If we care about anyone it is usually ourselves first of all. As Aristotle somewhere put it: luck is when the guy next to you gets hit with the arrow. Twenty-five hundred years of history have not changed man’s basic narcissism; most of the time, for most of us, this is still a workable definition of luck. It is one of the meaner aspects of narcissism that we feel that practically everyone is expendable except ourselves. We should feel prepared, as Emerson once put it, to recreate the whole world out of ourselves even if no one else existed. The thought frightens us; we don’t know how we could do it without others—yet at bottom the basic resource is there: we could suffice alone if need be, if we could trust ourselves as Emerson wanted. And if we don’t feel this trust emotionally, still most of us would struggle to survive with all our powers, no matter how many around us died. Our organism is ready to fill the world all alone, even if our mind shrinks at the thought. This narcissism is what keeps men marching into point-blank fire in wars: at heart one doesn’t feel that he will die, he only feels sorry for the man next to him. Freud’s explanation for this was that the unconscious does not know death or time: in man’s physiochemical, inner organic recesses he feels immortal.
