2012 Reprint of 1925 Edition. Exact facsimile of the original edition, not reproduced with Optical Recognition Software. In this book, conceived in 1922 and published in 1924, Sandor Ferenczi and Otto Rank were reacting against the practical fallout (transference and resistances in psychoanalytic treatment) from Freud’s ideas on repetition compulsion and analysis of the ego. This book introduced ideas and controversies that were taken up by later authors (Michael Balint, Donald W. Winnicott, Harold F. Searles, Jacques Lacan): the therapeutic use of object relations and regression; the analyst’s discretion (caution in interpretation); the analyst’s resistances and the role of countertransference; interest in training for physicians; and the risks inherent in training analysis.
