ABSTRACT
The most important evidence and product of Kraepelin’s point of view appear, if one examines his sub-division of the manic-depressive group. As we have seen, he recognizes mania with its elation and overproductivity of words and movements, depression with sadness, or anxiety and reduction in speech and activity and the “mixed conditions”. The latter must now claim our attention. In order to understand his argument it will be necessary first to digest briefly his account of the symptoms of mania and depression.
