Since all mass movements draw their adherents from the same types of humanity and appeal to the same types of mind, it follows: (a) all mass movements are competitive, and the gain of one in adherents is the loss of all the others; (b) all mass movements are interchangeable. One mass movement readily transforms itself into another. A religious movement may develop into a social revolution or a nationalist movement; a social revolution, into militant nationalism or a religious movement; a nationalist movement into a social revolution or a religious movement.
