A psychology of the war moods must undertake to trace the history of the motive of power, considering its beginnings as the desire and sense of satisfaction connected with the performance of definite instinctive acts, and with their physiological results, with the exertion of power and the production of effects upon objects. It is in the performance of instinctive acts, in which superiority is inborn, that animal and man obtain their original sense of power or superiority. As capacities are differentiated and multiplied, the experiences of achievement generate a mood and a more general impulse, a desire to exert power for its own sake. The sensory or organic elements tend to predominate in this generalized motive, simply because the specific actions in which the sense of power is obtained cannot so readily, or cannot at all, be generalized. Such an organization of actions and states in consciousness demands nothing new in principle, implies nothing different from that found on the intellectual side when concepts are formed from concrete experiences. The associative processes and the selective principles everywhere present in mental action are all that are necessary to be assumed here. We may take advantage, however, of the special investigations of affective logic, and the like, as giving evidence in support of such a conception of the formation of moods as is here being worked out. We are likely to make the mistake of thinking the specific instincts and the impulses and pleasure states that we find in human experiences, such as ecstasy, as the whole of these experiences, and to overlook the constant process of generalization that goes on in all the mental activity of the individual. For example, we may think of various plays which involve instinctive actions as being wholly explained by, or to be made up of, these instinctive acts alone, whereas in most plays that take the form of excitement, abandon or ecstasy, there are being employed processes which are general in the sense of reënforcing all the specific acts alike, and are yet specific in the sense that they are themselves, or have been, practical: that is, they are in reality processes that belong to the fundamental strata of consciousness—to the nutritional and reproductive tendencies. Out of these tendencies the more complex processes of which we speak are made, but they are no mere repetition of old forms. That, at least, is the way these ecstatic moods appear from our point of view.

It is precisely because ecstatic moods are presumably thus general and 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.

These moods which, slumbering, become the ecstasies of war are vague, even secretive. They contain aggressive thoughts that are disavowed, vanities that are concealed, fears that present a quiet front. But we must not think that the war mood always intends war. Nations have their subjective lives and inner history, and their vicarious satisfactions. A nation in arms already feels itself victor by reason of its sense of power. Otherwise few wars would be entered upon. Dreams and talk of war may incite to war, but they may also satisfy the desire and need of war. There is a certain narcissism in nations, and this is due precisely to the fact that patriotism as a feeling and impulse necessarily lacks in the group consciousness the mechanisms for externalization, except indeed in war. War is an escape, for a people, from a kind of subjectivism, from the evils of a self-love to perhaps the greater evils of self-assertion.

Nations in war, and even in the thought of war realize their own potentiality, take account of stock of their powers, and create an ideal, romantic and dream world. They make castles-in-air, and these castles-in-air always take the form of empires. War, precisely like art, is at first more and then less practical, and sought for practical purposes. More and more there is a craving for glory, for prestige, for subjective satisfaction and symbols of power. Nations take lands that they cannot use for any good purpose, inflict indemnities that may ruin themselves rather than their enemies, exploit economic relations that are dangerous to the nations' very existence. It is power that they seek, and it is power they thus create, but it is often different in form and in value from what the conscious purpose holds. They are really seeking general and subjective states in part for their own sake. Psychologically it is all one and the same whether we realize this power by actually killing an enemy, or believe we overpower him by the performance of some mystic and ecstatic act, or in some more modern way become confident in our own power and prestige. National life, in order to maintain its integrity, must move upon a plane of intense feeling. It must have objectives, but these objectives are not necessarily of value in themselves. This is the delusion and enigma of history. Peoples enact dramas in their own subjective lives, and these things they do have reference to the desires for inner experiences. We may say that nations, like individuals, crave for luxuries of the emotional life, but to think of these experiences as merely static pleasure-states, after the fashion of a certain conception of the emotions, would be wholly to misunderstand this view which we have been trying to present. These subjective states are full of meaning and of purpose. They are not reactions, but rather, in so far as these collective lives are normal and progressive, these moods and ecstasies are more of the nature of crucibles in which old reactions and feelings are fused, given new direction, new forms and in a certain way a new nature. History is made in these moods of war. They are subjective forces, but they are also objectively creative.

What is it that nations really desire? What is it, we might ask, that an individual desires? On the side of experience it is an abundant life, a life full of the feeling of power. This craving for an abundant life is a craving for the satisfaction of many desires, instinctive and acquired, but it is also a craving, in some sense, for more desire. It is not merely to satisfy desires, but to realize more life by creating more desires that experience is sought. That is the philosophy of the life of the superior individual; it is also the principle of the larger individual—the nation. The creation and the satisfaction of desire are the motives of art. They are also the motives of life.

In history, it is the intangible value, the unconscious purpose, the desire to realize empires that are only in part material, the desire for glory and prestige and opportunity that seem to be the guiding motives. There is a general and plastic purpose beneath all the special tendencies and desires directing interest toward specific objects, and also sometimes making the objectives sought indefinite and the purposes in seeking them seem mystical. It is the desire to be a power in the world, or rather to have power over the world, and to experience all the inner exaltation these desires inspire that appears to be the creative force in history. These things, moreover, are not the desires and impulses of the geniuses among nations alone; they seem to be inherent in all national life.

Study of the intoxication motive in the individual and as a social phenomenon shows that it is not an expression of the need of relaxation from strain, or a reversion, or something that occurs by a mere release of primitive instincts. It occurs in the great periods of history, and in the strong years of the life of the individual, rather than in times of weakness. It is always a spirit of the times rather than of some past reverted to. It may occur in times of disorder or of repression, but it is an experience in which energy and power are expressed. We see it most dominant when life is most abundant, when there is also a craving to make life more abundant still, when there is already power and more power is longed for. It is true, however, that two opposite conditions may produce the strongest manifestations of this intoxication motive. Something analogous to these conditions we see in the lives of individuals, in the phenomena of intemperance, which belong in general to the virile years. Social ecstasy is produced in times when there is already a free expression of energy, but also under conditions that cause pain, disorder and repression. Under the latter conditions we think of it not as desire for relief from strain but desire to be released from obstacles that impede the expression of the growth force. If all this be true, we see war in a somewhat different light from that in which it is ordinarily regarded. It is not, in its typical forms, a reversion to barbarism, and it is not a political mishap. It is rather a readjustment of tendencies or forces and an expression and product of the living and progressive forces of society—not necessarily a good or even a normal expression of them, but an awakening and a realization of such desires as are to-day at work in everything we do—forces which for the moment are raised to a white heat, so to speak, in which purposes are for the moment fused and it may be confused—but still an expression of what, for better or for worse we are, not of what in some remote past time we were. We cannot explain war or excuse ourselves for waging wars by saying that we lapse for a time into barbarism, but on the other hand the heroism we suddenly find in ourselves as nations or as individuals, is not so different from that of ordinary life as we may have supposed. We have perhaps no right to say that all war is thus to be characterized. War is a very complex and a widely variable phenomenon, but this is the explanation of that aspect of the motive of history which in general produces war. War may have its abnormalities, if we may speak of a worse in that which is already bad enough. War may satisfy the desperate mind; it may, on occasion, be a narcotic to cover up worse pain, or an evidence of decadence; or even be what those who think of it as a reversion believe. But all these aspects of war, if our view be sound, are the eccentricities rather than the essence of war.

The conditions preceding our recent great war will doubtless in the course of future historical and sociological research, be minutely scrutinized, in the effort to find the causes of the war—factors deeper than and different from the political and economic causes and the personal intrigues that are now most emphasized. If we believe that the war was made in Germany rather than elsewhere, we might look there, especially for these psychological factors of war—for our intoxication motives and unconscious impulses and our causes of reversion, but we should probably not find anything different in kind there from what we should discover in other great countries. Those who have seen in modern industrialism dangers of coming disaster, or who now look back upon it as a genuine cause of the war were probably not mistaken. Industrialism has been producing rapidly, and in an intense form, what we may call the mood of the city, and this mood of the city contains all the conditions and all the emotions that tend to bring to the surface the deep-lying motives of the social life that we are trying to point out. There are both the joy of the abundant life, the craving for new experiences, and the sense of reality, and also the disorganization of interests and motives, the stress and fatigue and monotony which prepare the mind for culmination in dramatic events. There is, in a word, a deep stirring of all the forces that make for progress and expansion, and also conditions that disorganize the individual and the social life. Lamprecht (59) of all German writers seems to have appreciated this. He has written before the war, describing a condition in Germany which he says began in the seventies of the preceding century—a change of German life in which there is a great increase of the activities of the cities, with haste and anxiety, unscrupulous individual energy, general nervous excitement, a condition of neuro-muscular weakness (and he might have added as another sign, over-stimulation of the mind by a great flood of morbid literature).

In Lamprecht's opinion, this period of excitement, this strong tendency to the enjoyment of excitation in general, is a form of socio-psychic dissociation. It is a period of relative disorganization, when the individual is subjected to a great variety of new experiences, when outside influences prevail over the inner impulses of the individual, in which the individual is unsettled and there is a tendency toward pessimism and melancholia. Lamprecht thinks of this state as something transitory, and already as he writes (in 1905) nearing an end. This state of continuous excitement, with its shallow pathos of the individual and its constant and superficial happiness, its worship of the novel and the extraordinary, the suggestibility and the receptivity of the masses, automatic action of the will and the emotions—all this Lamprecht thinks will pass. It is a stage in the process of a new formation. The very elements of dissociation are positively charged, so to speak, and contain creative power. A new system of morals, a new philosophy, new religion begin to emerge. There is a strong effort to reach a new dominant.
