ABSTRACT
Gradually the application of psycho-analytical principles to non-medical fields led to the conclusion that there is no variety of human behaviour, individual or social, that cannot be illuminated by understanding of man’s unconscious mind. Art and literature, sociology, anthropology, philosophy and religion were in turn subjected to the unsolicited attentions of research students, confident in their belief that what governs the mind of man must of necessity be expressed also in the institutions he has created. Now however little honour pioneers may gather in their own country, they have at least the satisfaction of knowing that they cannot justly be regarded as downright interlopers, Greater hardihood is demanded of those who, like the author of this courageous book, are bold enough to import into their own professional field the more unpopular findings of an alien science.
