This is an attempt to explain dementia præcox without any reference to psycho-analytical findings, 'not because I am unfamiliar with them, but rather because I have not been able to convince myself sufficiently of their validity'.
Much preliminary allusion is made to a previous monograph by the same author on the manic-depressive psychosis. In both monographs it is stated that this psychosis is essentially a disintegration due to a toxæmia, and reference is made to confusion and hallucinations as if they were characteristic symptoms of the malady. If they were, the diagnosis of toxæmia would be justified, but as they are not and disintegration does not take place in uncomplicated manic-depressive cases, it is evident that the former monograph is founded upon erroneous diagnoses.
The author considers that Kraepelin was not justified in recognizing three types of dementia præcox, viz.: hebephrenia, catatonia and dementia paranoides—because catatonic symptoms occur both in hebephrenia and dementia paranoides. This is rather puerile and seems to argue for a very limited experience of dementia præcox.
While rejecting Jung's concepts of extroversion and introversion the author substitutes:—
Altrocentric Traits and Egocentric Traits
Extrospective Introspective
Extroactive Seclusive
Sympathetic (altruistic) Egotistic
