Spock's book is considered a reasonably accurate statement of freudian psychology despite the fact that it is devoid of some of the basic concepts of psychoanalysis, such as dynamics, the pleasure principle, and topographic and structural theories. The book is appealing because of its presentation in acceptable form of the concepts of infantile sexuality, the unconscious, and Oedipal conflicts, as well as its legitimatization of such parental feelings as anger. Bach discusses the reasons for the popular acceptance of Spock's book and its relative neglect by psychoanalysts in contrast to Anna Freud's Psychoanalysis for Teachers and Parents, which is accepted by analysts but regrettably generally ignored by the public.
