Dr. Stewart, Clinical Associate Professor of Psychiatry at Einstein College of Medicine, is interested in presenting the dynamic and revolutionary years between 1888-1898 that comprised the first ten years of Freud's psychoanalytic conceptions. One aim: ""to show the continuity and modification that occurred as Freud developed his ideas."" Much of this material was drawn from the Fliess correspondence; other influences and associations (Ernst Bruecke, Joseph Breyer, Meynert, Charcot) are also noted. The study covers Freud's first observations, early views on sexuality, on economic formulations, effects, early metapsychology. Stewart remarks: ""It is impressive that those stages in infantile sexuality that are now taken for granted took twenty years to be understood."" Impressive, too, the inception and evolution of a seminal theory, still somewhat nascent here. No complete theory of analysis yet, no discovery of transference. Not for the uninformed reader, who will be snagged on the constancy principle or the psychic libido, but for the serious student of Freud's work.
