Sex, therefore, is an animal function, one admits, one insists; it may be only that. But also in the bewildering and humorous and tragic duality of all life's energies, it is the bridge to every eternity which is not merely a spectral condition of earth disembowelled of its lusts. For sex holds the substance of the image. But we must remember with Heine that Aristophanes is the God of this ironic earth, and that all argument is apparently vitiated from the start by the simple fact that Wagner and a rooster are given an analogous method of making love. And therefore it seems impeccable logic to say that all that is most unlike the rooster is the most spiritual part of love. All will agree on that, schisms only arise when one tries to decide what does go farthest from the bird's automatic mechanism. Certainly not a Dante-Beatrice affair which is only the negation of the rooster in terms of the swooning bombast of adolescence, the first onslaught of a force which the sufferer cannot control or inhabit with all the potentialities of his body and soul. But the rooster is troubled by no dreams of a divine orgy, no carnival-loves like Beethoven's _Fourth Symphony_, no heroic and shining lust gathering and swinging into a merry embrace like the third act of _Siegfried_. It is desire in this sense that goes farthest from the animal. Consciously, no one can achieve the act of love on earth as a completed thing of grace, with whatever delirium of delight, with whatever ingenious preciosity, we go through its process. Only as an image of beauty mated in some strange hermaphroditic ecstasy is that possible. I mean only as a dream projected into a hypothetical, a real heaven. But on earth we cannot complete the cycle in consciousness that would give us the freedom of an image in which two identities mysteriously realize their separate unities by the absorption of a third thing, the constructive rhythm of a work of art. It is thus that Tristan and Isolde become wholly distinct individuals, yet wholly submerged in the unity that is Wagner; and so reconcile life's duality by balancing its opposing laughters in a definite form--thereby sending out into life a profounder duality than existed before. A Platonic equipoise, Nietzsche's Eternal Recurrence--the only real philosophic problem, therefore one of which these two philosophers alone are aware.
