Attentively reading Ferenczi's works and his scientific and "auto-analytic"
correspondence with Sigmund Freud, the Author insists on the important con
tribution of the Hungarian psychoanalyst concerning the contemporary matter
of the complex relations between biology and psychoanalysis: Ferenczi cons
idered in fact that the unconscious was an occult phenomenon allowing an in
tersubjective thought-transference and was desperately searching for the ma
terial evidence of traumatic scenes and life events, reducing the psychical
reality to a body-writing. Freud was contrarily and prudently convinced th
at the unconscious processes were dependant of the materiality of the regis
trar of the signifier surely constitued by corporal traces, but that had to
be understood in his relations more with language and speech phenomenons t
han fallacious sensation's reality.
