each one of us behaves in some respect like the paranoiac, substituting a wish-fulfilment for some aspect of the world which is unbearable to him, and carrying this delusion through into reality. When a large number of people make this attempt together and try to obtain assurance of happiness and protection from suffering by a delusional transformation of reality, it acquires special significance. The religions of humanity, too, must be classified as mass-delusions of this kind. Needless to say, no one who shares a delusion recognizes it as such.
