Totem, taboo, demon worship, etc., are clearly primitive crowd-phenomena. Freud's main argument in this book consists in showing the likeness between these phenomena and the compulsion neurosis. The projection of unconscious hostility upon demons is by no means the only sort of which crowds both primitive and modern are capable. Neither must the hostility always be unconscious. Projection is a common device whereby even normal and isolated individuals justify themselves in hating. Most of us love to think evil of our enemies and opponents. Just as two fighting schoolboys will each declare that the other "began it," so our dislike of people often first appears to our consciousness as a conviction that they dislike or entertain unfriendly designs upon us. There is a common type of female neurotic whose repressed erotic wishes appear in the form of repeated accusations that various of her men acquaintances are guilty of making improper advances to her. When the "white slavery" reform movement swept over the country--an awakening of the public conscience which would have accomplished a more unmixed good if it had not been taken up in the usual crowd-spirit--it was interesting to watch the newspapers and sensational propagandist speakers as they deliberately encouraged these pathological phenomena in young people. The close psychological relation between the neurosis and the crowd-mind is shown by the fact that the two so frequently appear at the same moment, play so easily into each other's hands, and are apparently reactions to the very same social situation.
