Not all crowd-movements, however, are local and temporary. There are passing moments of crowd-experience which are often too sweet to lose. The lapse into everyday realism is like "falling from grace." The crowd state of mind strives often to keep itself in countenance by perpetuating the peculiar social-psychic conditions in which it can operate. There are certain forms of the ego consciousness which are best served by the fictions of the crowd. An analogy here is found in paranoia, where the individual's morbid fixed ideas are really devices for the protection of his self-esteem. The repressed infantile psyche which exists in us all, and in certain neurotics turns back and attaches itself to the image of the parent, finds also in the crowd a path for expression. It provides a perpetual interest in keeping the crowd-state alive. Notice how invariably former students form alumni associations, and returned soldiers at once effect permanent organizations; persons who have been converted in one of Mr. Sunday's religious campaigns do the same thing--indeed there are associations of all sorts growing out of these exciting moments in people's common past experience, the purpose of which is mutually to recall the old days and aid one another in keeping alive the enlarged self-feeling. In addition to this, society is filled with what might be called "struggle groups" organized for the survival and dominance of similarly constituted or situated people. Each group has its peculiar interests, economic, spiritual, racial, etc., and each such interest is a mixture of conscious and unconscious purposes. These groups become sects, cults, partisan movements, class struggles. They develop propaganda, ritual, orthodoxies, dogma, all of which are hardly anything more than stereotyped systems of crowd-ideas. These systems differ from those of the neurosis in that the former are less idiosyncratic, but they undoubtedly perform much the same function. The primary aim of every such crowd is to keep itself together as a crowd. Hardly less important is the desire of its members to dominate over all outsiders. The professed purpose is to serve some cause or principle of universal import. Thus the crowd idealizes itself as an end, makes sanctities of its own survival values, and holds up its ideals to all men, demanding that every knee shall bow and every tongue confess--which is to say, that the crowd believes in its own future supremacy, the members of the group knowing that such a belief has survival value. This principle is used by every politician in predicting that his party is bound to win at the next election.
