The author presents an objective review of the theories and practices of John Rosen, who views psychosis as a psychogenic disorder susceptible to a psychological type of treatment. In 'direct psychoanalysis' emphasis is placed on the difference in technique in the 'phase of resolution of the psychosis' and in treatment of the 'neo-neurosis', and the author stresses that this difference is important in answering some of the criticisms of Rosen's theories. He also points out that Rosen differed from Freud in his views on the superego, the question of transference in the psychoses, and in his definition of the Oedipus complex.
