composite, and involve fundamental instincts (but in such a way that they are transformed, and no longer present in body, so to speak, but are represented by their organic processes rather than appearing as specific concatenated chains of motor events), with their purposes changed and their whole meaning determined by the present states to which they belong, that we should be inclined to say that to explain any great and powerful movement in the lives of individuals or nations as merely reversions is very inadequate and indeed wrong. They are emotional forces that are at work, composite feelings and moods rather than instincts. They are aspects of the continuity of the life of the present, rather than of the fragmentary past that lives in the individual. These forces are plastic, complex and organized, rather than haphazard and suppressed. They are directive, creative, but incidentally they make amends for and satisfy and exploit the past.

If these principles be valid, their application to the psychology of war seems plain. The central purpose or motive of war to-day is a craving for the realization of the sense of power. This is the subjective side of it, the unconscious, instinctive, mystical motive so often observed. The question of the actual power exerted or displayed is not the most essential point of this war mood. It is the manipulation and the satisfaction of inner factors that make the most significant aspect of these moods. History, we should hold, is in great part an unfoldment of this motive. Nations crave, as collective or group consciousness, the feeling of power. Just as we say the child in his plays wants to be a man, and the individual in his art feels himself a god, so nations in their wars and in their thoughts of wars, feel themselves more real, realize themselves as world powers, and as supreme and divine. To be first and all is indeed the purpose that runs in these moods, and this we believe is true, in its way, of the most insignificant and hopelessly decrepit of peoples. This must be taken account of in the interpretation of history, and in that larger pedagogy, the pedagogy of nations to which we just now look forward.
