Our agreements and our disagreements become apparent in the first paragraph. Hogan states that psychosomatic medicine implies neither a linear progrcssion not a temporal succession. I agree with that. However, he goes on to say that according to the areas of observation, the somatic or the psychical, there are two separate sources of data. I think we are dealing with two modes of observation which are totally separate from one another, but which derive from a unitary source.
Man is psychosomatic by definition.
I therefore believe in his somato-psychical unity. Psychoanalysis, as a new discipline, brings an original revolutionary answer to the eternal psyche-soma debate. Freud was the first one to show that the pathways from mind to soma do not in themselves allow us to distinguish the psychical sphere from the somatic one. On the other hand, he early on contrasted the sexual drives with the instincts of preservation and, later on, the erotic libido with the death instincts, and he thus displaced the old psychesoma dualism with a drive dualism. We find different kinds of interpretations in thc same bodily locations, just as antagonistic forces are at work in the same place.
