These changes in the social life in time of war are striking and fundamental. To explain them would mean to explain social feeling itself. We may say that these phenomena of the social life are precisely the _herd reactions_ the biological writers speak of, but to do so would mean, from our point of view, to ignore some very significant aspects of human social life. It would ignore first of all the ecstatic quality of the higher social life, which is indeed the essential quality of the social spirit of war. Instead of saying that this intensity of feeling is merely a reflex of an instinctive reaction, we should say that it is the expression of, and in part the satisfaction of, desires that are fulfilled in the social experience of war. The intense social life is craved, not as an instinctive reaction, but as a complex state expressing explicit desires. The craving for this social solidarity and ecstasy of social feeling is a factor in the causes of war. What we experience socially in times of peace is a society in which social feeling is narrow and provincial, in which we are conscious of many antagonistic motives. This social life fails to satisfy the desires which are seeking expression in the social life. That war is in part a creation of the social impulse seeking expression may be assumed from the nature of the social feelings that are excited in war. That such social feeling is a creation in the sense that it is desired, we see if in no other way in the fact that social ecstasy is the most universal form of satisfaction of all those impulses which fuse in the intoxication impulse, where we recognize it as the craving for an abundant or real life. Life is most real in its intensely dramatic social forms. Social ecstasy is in part a conscious adaptation. It is something that is desired and induced, and artificially cultivated in various ways, especially by a variety of aesthetic social experiences, and in the cults of intoxication. Alcohol has been used specifically throughout the world and from the beginning at least of the historical period for the purpose of creating social feeling. Patriotism is in part, we may say, a cultivated, social emotion, and in the art of manners we see the social life given forms which will increase its susceptibility to suggestion, its persuasive force and its organized expression. Such facts show us social emotion which is something more than the feeling side of an instinctive reaction.
