To Jolande Jacobi
Dear Dr. Jacobi, 12 June 1945
I would answer your question as follows: It is a fact that intelligence and psychological preparation in cases of schizophrenia result in a better prognosis.
I therefore make it a rule to give anyone threatened with schizophrenia, or the mild or latent schizophrenic, as much psychological knowledge as possible, because I know from experience that there is then a
better chance of his getting out of the psychotic interval.
Equally, psychological enlightenment after a psychotic attack can be extraordinarily helpful in some circumstances.
I am not convinced that schizophrenia is absolutely fatal any more than tuberculosis is.
I would always recommend psychological education to patients at risk as a measure of prophylactic hygiene.
Like neurosis, psychosis in its inner course is a process of individuation, but one that is usually not joined up with consciousness and therefore runs its course in the unconscious as an Ouroboros.
Psychological preparation joins the process to consciousness, or rather, there is a chance of its being joined, and hence of the individuation process having a healing effect.
Hoping I have answered your question satisfactorily, and with best regards,
C.G. Jung, ~Carl Jung, Letters Vol. 1, Page 371.
