It is true that whenever a crisis broke out Freud invariably showed himself what he really was, a truly great man, who was always accessible and tolerant to new ideas, who was always willing to stop, think anew, even if it meant re-examining even his most basic concepts, in order to find a possibility for understanding what might be valuable in any new idea. The relationship between Sigmund Freud and Sándor Ferenczi is described as a controversial dialogue about central subjects in psychoanalysis, the repression of which has had negative effects upon the development of psychoanalysis. Right up to the present day, the relationship between Freud and Ferenczi has been a difficult topic for psychoanalysis. Freud and Ferenczi visited one another. Ferenczi gave hospitality to Anna Freud in Hungary, supplied the Freud family with food and patients during and after the war; Freud kept Ferenczi informed about happenings in his family, and the fate of his sons in the war.
