Jung says the following in his introduction: "in these lectures I have attempted to reconcile my practical experiences in psychoanalysis with the existing theory, or rather, with the approaches to such a theory." He goes on to say, "Here is my attitude towards those principles which my honored teacher Sigmund Freud has evolved from the experience of many decades." Some topics considered in this light are infantile sexuality, the conception of the libido, the unconscious, the dream, repression, and the etiology of neuroses.

A collection of classical writings of Swiss psychologist Carl G. Jung, an influential thinker and the founder of analytical psychology. Written at intervals over a span of fourteen years, these selected articles and pamphlets contain many fascinating ideas that have become widely accepted psychological concepts nowadays, but had just started to develop at the time when the book was written. For instance, this is where Dr. Jung's ideas of introversion and extroversion, a contribution of vital importance to psychology, appeared for the very first time. Other topics explored include the concept of the unconscious, the study of psychological types, and the psychology of dreams.

Jung says in his subtitle that this work is a study of the transformations and symbolisms of the libido and a contribution to the history of the evolution of thought.
