"This first book by Perls is significant because in addition to criticising Freud, it also lays the groundwork for a new system of psychotherapy. In fact it is the beginning of the gestalt therapy by one of the founding fathers of this therapy. Ehrenwald p. 505:" Frederick Perls received his M.D. in Berlin in 1921. Like Wilhelm Reich he started out as a Freudian analyst, but under the influence of Kohler, Wertheimer and Kurt Goldstein developed his own school of analysis: Gestalt Therapy. His principles of gestalt therapy have been adopted by countless encounter and sensitivity groups."
"..aims in this book to examine some psychological and psychopathological reactions of the human organism within its environment..The author is criticsl of orthodox psycho-analysis, and claims that the use of the new intellectual tools holism (field conception) and semantics (the meaning of meaning) can greatly improve our theoretical outlook."
