According to Kasanin, magic thinking, megalomania, confusion about one's own sex and the feeling that other people know one's thoughts are manifestations of the characteristic regression of schizophrenic patients. Kasanin points out that the idea of regression does not imply that the adult patient becomes a child again. 'All we can say is that a schizophrenic in his illness goes through certain phases in his regression which are somewhat analogous to certain phases in the maturation of a child.' The most important remark in this paper seems to be the admission that regression is a purely descriptive term as long as the underlying dynamic force which brings about the regression is not demonstrated.
