The Ferenczi-Jones correspondence presented here is an important document of the early history of psychoanalysis. It spans more than two decades, and addresses many of the relevant issues of the psychoanalytic movement between 1911-1933, such as Freud's relation to Stekel, Adler and Jung; the First World Wa;, the debates of the 1920s regarding the theoretical and technical ideas of Rank and Ferenczi; problems of leadership, structure, and finding a centre for the psychoanalytical movement; as well as issues related to telepathy and lay analysis.
