The author has gone to considerable effort to explore the major writings by and about Freud for references to the relationship between Freud and Nietzsche. He found only a dozen references and of these one has Freud stating that Nietzsche's ideas have had no influence whatsoever on his work. Mazlish does not emphasize Freud's calling attention to Nietzsche's serious illness, general paralysis. He does not suggest that the megalomania often associated with this illness might be related to some of Nietzsche's grandiose statements. Nietzsche's concept of Superman viewed from a freudian approach makes an interesting discussion in this scholarly article.
