We shall have to preserve the same attitude with regard to a new work of the well-known Leipsic professor Dr. STRUMPELL—_Die pädogogische Pathologie oder die Lehre von den Fehlern der Kinder_, Leipsic, 1890, Verlag von Georg Böhme Nachfolger. We must refer here to this otherwise highly deserving book only in one respect, where we have occasion for censure. The author does not in his expositions sufficiently take account of the intimate connection between physical and mental phenomena, and the consequence of this is among other things that he excludes pathological mental conditions (the physical causes of which he is forced to admit) as a matter of principle from the pedagogic system and consigns them entirely into the charge of the physician. In our treatise mentioned we have explained why this is not allowable, as well as, in addition, what portion of duty devolves on the teacher in the consideration of these pathological mental conditions. Strumpell’s mistake springs from the fact that he conceives with Herbart the essential object of education to be intellectual culture. Allowing that Herbart cannot be taken to task for entertaining this conception, we may yet demand of Strumpell the recognition of the results of recent physiological psychology to the extent at least of perceiving that psychical and physical phenomena are _one_ if not the _same_. Even the opponents of Monism dare not overlook this truth,—a truth moreover that admits very well of reconciliation with the Herbartian pluralism to which Strumpell is devoted.
