Disturbance of self-evidence and delusion

Psychopathologically we study the process from the disturbance of self-evidence to the formation of delusions. When delusions arise on the basis of the disturbance of self-evidence, this disturbance impairs the way of judgment. We present a case of schizophrenia in which the unlimited questions about grounds make it impossible for the patient to establish the self-evident as itself and to judge inductively. The formation of delusions is the psychopathological extrication from the impairment of the inductive judgment. In the formation of delusions on the basis of the disturbance of self-evidence, we can observe the process from the weakening to the substantiation toward the outside of the transcendental organization.
