Schizophrenic thinking is archaic thinking. This is not only true in the sense of a similarity between the thinking of schizophrenics and of infants, but also in the sense that the functions of certain higher regulating centers cease or diminish. Schizophrenic thinking points to the functioning of deeper, subcortical parts of the brain, those which are responsible for cataplexy.

Bychowski contributes a detailed analysis of a few excerpts of a case history and adds an exact description of the methods of schizophrenic thinking with stimulating speculations as to the underlying physiological processes.
