ABSTRACT
The more precise and dogmatic these formulations become, the more incumbent it is on the psycho-analyst to test them in the psychiatric field. It may occur to you to ask why psycho-analysts are not content to mould their formulations to existing psychiatric classifications. Before expounding the principles governing psycho-analytical classifications of the psychoses, the authors may inquire to what general conditions an adequate system of classification should conform. There is ample scope, especially in the case of schizophrenia, and the so-called toxic psychoses, for isolating syndromes, the value of which could be tested by analysis of psychotic and non-psychotic types. The concept of a hallucinatory pan-psychosis is a trifle hypothetical, although during the earliest infantile stage (sucking) there are hallucinatory phenomena enough and to spare. On the other hand, actual clinical analysis of psychotic children shows that the second main subdivision (introjective and projective psychoses) corresponds with the facts.
