One fifth only of this book has previously been published in English. It
has all been revised and the greater part largely re-written. The light
which psycho-analysis is capable of throwing on the deeper problems of
human thought and conduct is only beginning to be appreciated. The field
over which it can be applied is almost indefinitely large. The parts
touched on in the present volume constitute of course only a selection,
yet they are sufficiently diverse political psychology, artistic and
literary creation, national and indiv idual characterology, and the
study of superstition, history, religion, and folk-lore.
