It would be going too far afield to try to summarize here the psychology of moods or of the motive of power in the individual and in society, but the main fact needed for the moment seems plain. In this motive and its expression in feeling and conduct there is a very general tendency which is the source of many forms of interest and enthusiasm, of ambition, of the spirit of war, of various kinds of excitement, and to some extent of morbid and criminal tendencies. The spirit of war we think of as a summation of the same forces as those which in other ways appear as the energies behind various enterprises having quite different objectives. War is an anachronism, we may believe, a wrong direction taken by the forces of the social life, an archaic expression now, let us say, of the will to power which might and ought to have different objectives. In the life and the mood of the great city we see a very varied expression of the motive of power. The city life is still a crude life. It satisfies deep desires, but in it desires for we know not what are aroused. It is indeed as the seat of eager, unsatisfied desire that the city is best of all characterized. These desires readily take shape in the city as the spirit of war and as a craving for excitement of various kinds. These same forces re-directed or finding different objects and working under different conditions appear in moral, religious, or aesthetic forms. In these higher experiences and more progressive moments in history or in the life of the individual, the forces which at other levels emerge in different forms and in search of different objects we may think of as transformed, or given new direction; but to suppose them annihilated or suppressed is to misunderstand, according to our view, the whole process of the development of spirit. Life is not a process in which instincts are balanced, or in which good motives stand in sharp contrast to bad motives, or in which an original selfishness is opposed and gradually overcome by an altruistic motive. We think rather of very complex processes in which many desires, gathered into moods, find many forms of expression. There are prevailing moods--of war and of peace--and these moods are deep forces, containing both the desires and the sources of energy, so to speak, out of which our future will be made. The ecstatic states of the social life, the moods of war and the enthusiasm of the periods of rapid change are conditions in which energies and purposes are deeply stirred. These are the moods of _intoxication_, if we wish to describe them by pointing out one of their chief common characteristics. Peace is a _reverie_, we may say, in which the purposes and the results expressed and attained in the more dramatic moments are elaborated and fulfilled, and in which new impulse is gathered of which the dramatic moment is itself the expression. But throughout the whole course of history and through all the life of the individual, the same motives
