Part II. The Psychology of Friedrich Nietzsche as a Psychopathological Problem

An intellect who wishes to grasp the evolution of the world and of humanity through his thoughts, needs the gift of imagination, which brings him to these thoughts, as well as self-discipline, self-criticism, through which these thoughts attain their meaning, their importance, their connection. This self-discipline does not exist to any great extent in Nietzsche. The ideas storm in upon him, without being kept in check by his self-criticism. There is no reciprocal relationship between his productivity and logic. No corresponding degree of critical thoughtfulness stands side by side with his intuition.
