That time (1902), Jung was impressed especially by the emphasis on the method of free associations that
resembled his own experiences with associations.Freud has developed this method in psychoanalytical therapy and has applied it as well in the dream analysis. The difference is that in the interpretation of dreams
Freud's method is applied accordingly to a piece of dream, which has to be associated this way.
The visit to Vienna of the enthusiastic Jung meant the beginning of an extremely profitable and passional
collaboration for the "cause" (promoting the psychoanalysis as therapy method and theory). Freud considered Jung his successor, and this explain Jung's assuming the position of President of the
International Psychoanalytic Society.
In though, he was not thereby attracted by the sexual etiology of neurosis, Jung, with an extraordinary and unrestrained energy, did his best in order to impose
psychoanalysis into the scientific world of that time.
He had two advantages in his task: 1. he was working with the famous doctor Bleuler, the Director of the notorious clinic of Burgholzli, and 2. he was not a
Jew, so he did a lot in order to protect psychoanalysis from the claim it was a Jewish affair. His warlike character brought many services to the developing of Freudian psychoanalysis.
There are many letters written, one to each other, by Freud and Jung that offer us details about the important moments of the beginning and the evolution of psychoanalysis. AROPA
