“…Seen in this light, ritual possession takes on aspects of a ritual of salvation since it allows a latently ill person to establish some kind of mental balance through the adoption of several personalities. Other authors, such as Ackerknecht (1943), Nadel (1965), Gillin (1948), Boyer (1961-1962-1964, and Sasaki (1969),4 tend to see the shaman as a neurotic rather than as a psychotic personality; he is believed to be suffering for the most part from hysteria (proof of this is his ability to control his dissociated state, i.e., the trance); also, he plays an important role in his society and is distinguished from the rest of those designated as &dquo;insane.&dquo; Silverman (1967), basing his ideas on a distinction between two forms of schizophrenia -an idea first introduced by Chapman and Baxter (1963), who distinguished between &dquo;process&dquo; schizophrenia, which is long, evolving, ever worsening, and manifests itself quite early in life; and &dquo;reactional&dquo; schizophrenia, which involves excellent adaptability to the group and appears suddenly although late in life, with a rapid resolution -believes the shaman to be a paranoid schizophrenic. According to this author, shamanism is a process of incomplete resolution although it does offer a &dquo;solution&dquo; to the extent that the problem is allowed to follow its course in a supportive atmosphere and results in the reintegration of the individual personality in society.…”
