Freud's psychology and its organic foundation: sexuality and mind-body interactionism

Although Freud's neurological education had a great impact on his thinking, a review of Freud's early writings reveals that: (1) Freud adhered to a mind-body interactionist position that was not in accord with the mechanistic neurology of his medical school education; (2) Freud saw psychical processes as intentional, not completely determined by mechanical brain processes--but interactive with them; (3) Freud made functional and psychological interpretations freely without accepting a need to "neurologize" his psychological insights by providing specific neuroanatomical or neurophysiological correlates for such interpretations; and (4) Freud sought the organic base for his evolving psychology in sexual physiology, not neuroanatomy or neurophysiology.
