The author begins with a biographical sketch followed by a brief outline of Freudian, Jungian and Adlerian psychology. Her attitude to psycho-analysis is critical. She gives an outline of the essentials of Rank's psycho-therapy and emphasizes its relation to the mother-child situation. In her comparison with and criticism of psycho-analysis, she appears to ignore the developments in psycho-analysis which have arisen out of child analysis and progress in the understanding of the psychology of woman, and the effect of these, together with the influence of Rank's work, on Psycho-analysis.
