What is the gospel of this ambiguous prophet? It is, he himself declares, a long "Memento vivere." His own experience taught him that the characteristic of life, in its highest moments, is to be unimaginably alive. From a mere process it becomes a sudden intoxication, and on the psychology of that intoxication, which is the psychology of the artist and also that of the lover and the saint, he has written pages which are a wonder of pure light. From this standpoint he criticises justly the mechanical theory of adjustments in which there is nothing to adjust, of adaptations in which there is nothing to adapt, the whole _ab extra_ interpretation of life popularised by Darwin, Spencer, and the English school in general. The living unit is more than a mere node or knot in a tangle of natural selection; it is a fountain of force, of spontaneity, constantly overflowing. "The general aspect of life is not indigence and famine, but on the contrary richness, opulence, even an absurd prodigality." To live is for Nietzsche, as for the Scholastics, to be a centre of self-movement. With the Pragmatists he asserts the primacy of life over thought. But this tension of consciousness, this Dionysiac drunkenness, is only a foundation, it is not yet a philosophy. Philosophy, or at all events moral philosophy, begins with the discovery that there are other people in the world. Your ego, thus drunken and expansive, collides sharply with another ego, equally drunken and expansive, and it becomes at once necessary to frame a code of relations, a rule of the road. Is this force and spontaneity of the individual to flow out towards others through the channel of domination or through that of love?
