Abstract

This paper demonstrates what Bleuler, Freud and Jung had in common in 1908, but it also highlights their theoretical differences in relation to the aetiology of dementia praecox or what Bleuler that year called the “schizophrenias”. It also reveals that both Bleuler and Freud had questions about Jung’s diagnosing dementia praecox in Otto Gross and it points out that Freud held Jung responsible for Bleuler’s distancing himself from the psychoanalytic movement.
