The analytic psychotherapist thus has a threefold battle to wage -- in his own mind against the forces which seek to drag him down from the analytic level; outside the analysis, against opponents who dispute the importance he attaches to the sexual instinctual forces and hinder him from making use of them in his scientific technique; and inside the analysis, against his patients, who at first behave like opponents but later on reveal the overvaluation of sexual life which dominates them, and who try to make him captive to their socially untamed passion.
Sigmund Freud (May 6, 1856 - September 23, 1939) was an Austrian neuroscientist who left the laboratory to go into private practice as a neurologist. He founded the clinical and theoretical school of psychoanalysis which holds that human development progresses through a sequence of psychosexual stages which may be interfered with by internalized psychosocial conflicts. To cope with intrapsychic conflict the unconscious mind initiates a defensive process called repression in order to prevent unacceptable sexual and aggressive wishes from becoming conscious, however they remain active in the unconscious and continue to strive for expression. Most commonly, benign evidence of repressed contents can be seen in dreams, jokes, and various Freudian slips. When the mind has to cope with a serious failure of defensive repression, we see the development of symptom constellations called neurosis, which can be treated by bringing the repressed wishes fully and safely into consciousness and releasing the associated pent up emotional accumulation. Freud sought to accomplish this in the privacy and safety of the treatment situation.
