[Human nature--understanding psychology in Nietzsche]

It was tried to show some decisive and essential points of the psychological analyses contained in the complex work of the philosopher Nietzsche. The extent of his knowledge of man and his changeability constitutes here the field of an understanding, "unmasking" psychology with a sociological-historical touch. The thorough, slow ("lento") study of the original sources on the part of the master of a "connaisseurship of the word" seems to be indispensable for any reader trying to occupy himself with Nietzsche in a work of his own and the questions arising therefrom.
