or cruelty, but it is a product of original endowment, of conditions of life, and of intelligence all together. It is practical, but at no stage can it be said to be wholly practical. Changes must have taken place in warfare as in other social reactions as men passed through a number of stages from primitive wandering or a relatively unstable life to a stable life, but the motives of conflict cannot have been added to in any essential way. Through all the course of history all the motives that originally made individuals of a group or the groups as wholes antagonistic have remained, although the mental processes have become generalized, fused and transformed. If Gumplowicz is right we can still detect in any great society to-day all the primitive individual and group animosities, tempered down and held in check by laws and customs, but still existent and by no means overcome and made innocuous.
These motives of warfare might best be traced out in four more or less definite principles of conduct, or four purposes of war that appear throughout primitive life. These are: 1) thievery, including wife capture; 2) the fear motive; 3) cannibalism; 4) the display motive, with the desire to intimidate and to display power (more or less closely associated with the play motive, the love of hunting, gaming and the dramatic motive).
Cannibalism, of course, is a special expression of the predatory motive in general, or it is mainly that. Cannibalism was certainly established early in primitive life, at least early enough to antedate all religion, and although its origin and history are shrouded in mystery, the motive was quite certainly practical. Evidently it was widespread if not universal. Whether it was introduced as a result of a failure of animal food, as some think, or has a still more simple explanation as a part of the original impulse which led men at a certain stage of their development to become hunters, cannot be determined. We know, however, that the alien human being was to some extent included under the same concepts as the animal enemy and prey, and presumably some of the strongest motives that led men to attack animals also included man as an object, since the alien group was regarded as in some degree different in kind from the in-group. It may have been in the great migrations when all the aggressive motives were increased that cannibalism became fixed as a habit.
Cannibalism may well have been the primitive motive of warfare as serious deadly combat, but all predatory habits must have contributed to establishing a more or less habitual state of warfare among all groups of men. The predatory raid, with the reaction of defense, when carried on as a group activity in any form, is in fact war, so far as attack and defense were serious and deadly, and intelligence and weapons were sufficiently developed to make man a dangerous opponent. This predatory motive, of course, extended to all desired objects, and these objects must have included all objects that could most simply be acquired by stealing. They included food, women, and all other possessions. The custom of driving out young males from the group, by the jealousy of the old males, and of preventing males from obtaining females within the group must have been one of the earliest and one of the strongest incentives to predatory warfare. At first all property of the group, for so long as groups were wandering, was to some extent common, and attack and defense must have been common. The objects of predatory raids which produced group combat must have changed with the social life. When habitation became fixed and property therefore more individual, probably the predatory impulse itself became relatively a less important factor in combat.
Two motives grow out of the practical motives of combat, which we may assume to have been the original motives. These are both emotional rather than instinctive. Fear and anger, that is to say, become more or less detached motives for attack. Fear is increased with the increase of intelligence up to a certain point at least--with the increase of the capacity for understanding danger, and of the powers of man to become dangerous. All the experience of combat engenders anger and hatred, and these moods of hatred toward enemies are cumulative, absorb all the detached motives and feelings of antagonism between groups, preserve and give continuity to the memories of conflict, and so produce among groups the fear and hate motive. The feeling of fear arouses the motive of aggression, and the feeling of anger; and these in turn generate more fear, until both the moods of anger and fear and a perpetual state of animosity and warfare are induced among contending groups. Thus out of primitive motives of combat
