Nietzsche and Freud.

By Dimitrov, Christo; Jablenski, Assen

Revista de Psicoanálisis Psiquiatrîa y Psicologîa, Vol 9, 1968, 46-65.

Examines Nietzsche's influence on Freud's psychoanalytic work. Similarities between their thinking on various psychological considerations (the psychological mechanism, dreams, repression, sublimation, personality development, health and illness, etc.) are analyzed. Their conceptual differences are noted primarily in Freud's scientific attitude toward psychology, particularly with respect to his evolutionist views on instincts. Freud also conceived a more positive, consistent, and independent role for the unconscious. Contemporary evaluations of psychoanalysis (e.g., "materialistic naturalism," and "subjective idealism") are followed by a critique that underlines Freud's simplification of reality and idealistic generalizations.

Freud and Nietzsche: a comparison.

By Brandt, Rudolf

Revue de l'Universite d'Ottawa, Apr 1955, 225-234.

A comparison of Freud and Nietzsche shows a similarity in Weltanschauung and a conflict in their religious and sexual spheres. But the striking resemblance carries on in the following concepts which antedated Freud's own development of them: the unconscious; the dream as a psychic reality; the basic nature of the sexual drive; and such mechanisms as ambivalence, repression, isolation, reaction formation, sublimation, projection, etc. Speculation is offered to explain this similarity.

Friedrich Nietzsche und Sigmund Freud. / Friedrich Nietzsche and Sigmund Freud.

By Tramer, F.

Jahrbuch für Psychologie, Psychotherapie und Medizinische Anthropologie, Vol 7(3-4), 1960, 325-350.

A study of the various writings of Neitzsche shows that one can find there a definite indication of the thought of the unconscious, guilt feeling, and the concept of conscience. It appears that the philosophical considerations of Nietzsche were picked up by Freud who then continued working on them and who incorporated them into his scientific approach.

Freud and Nietzsche.

By Mazlish, Bruce

Psychoanalytic Review, Vol 55(3), 1968, 360-375.

Freud: (a) borrowed a few catch phrases from Nietzsche, (b) expressed admiration for Nietzsche as one of the intuitive forerunners of some of the insights psychoanalysis laboriously acquired by other means, (c) was annoyed when his own work was attributed to Nietzsche, (d) repeatedly denied that he secured any of his ideas or inspiration from Nietzsche, and (e) said that Nietzsche was ignorant of the role of infantilism and displacement. The differences between Freud and Nietzsche mark the decisive step in the advance from philosophy to science in the field of depth psychology.

 Freud's relationship to Nietzsche: Some preliminary considerations.

By Lehrer, Ronald

Psychoanalytic Review, Vol 83(3), Jun 1996, 363-394.

From the early years in the development of psychoanalysis through the present day, there has been discussion and debate regarding the extent to which Nietzsche discussed and elaborated upon ideas generally ascribed to Freud as well as the extent to which Freud may have been influenced by Nietzsche in the development of a number of fundamental psychoanalytic concepts. Nietzsche and Freud were undoubtedly influenced by some of the same or related sources on dreams and, more generally, theories of energy and unconscious mental processes. However, in important respects, their psychologies diverge at numerous points. Nietzsche was a towering figure in Freud's Vienna of the early 1870s and in the German-speaking world by the early 1890s. Studying the relationship between Nietzsche and Freud should include an assessment of Nietzsche's anticipation of and impact on Freud, as well as a study of Nietzsche's psychology in its own right.

Freud's devaluation of Nietzsche.

By Scavio, Michael J.; Cooper, Andrew; Clift, Pamela S.

Psychohistory Review, Vol 21(3), 1993, 295-318.

Explains Freud's change of mind concerning Nietzsche's influence on the development of psychoanalysis. Similarities between Nietzsche's and Freud's systems are reviewed, Freud's early felicitous reactions to and later disapproval of Nietzsche are documented, and the experiences in Freud's life that appear to be the basis for his devaluation of Nietzsche are recounted. The paper concludes with a hypothesis that explains how Freud's personal experiences motivated his change in belief about Nietzsche's connection to psychoanalysis.

Nietzsche and Freud: Two voices from the underground.

By Roazen, Paul

Psychohistory Review, Vol 19(3), 1991, 327-349.

Discusses the implications of Nietzsche's (1927) disturbing philosophy and its spiritual subversiveness as it is echoed throughout Freud's thinking. Freud rarely wrote about positive self-esteem, but he did suppose like Nietzsche that moral convictions rested on the internalization of aggression. Both Nietzsche and Freud had emerged from the underground of Western thought, and they each sought to challenge key aspects of traditional morality. It is argued that Freud's work, especially in North America, has been tamed and conventionalized and that to be reminded of the more alarming components of Freud's teachings would be to threaten not only the professional status quo of analysis but to threaten the received sense of self from the rest of Freud's theory. However, Freud was not advocating ethical anarchy so much as trying to replace traditional ethics with a higher morality. Psychoanalysis was intended as an ethic of self-overcoming.

Jaspers, Mann and the Nazis on Nietzsche and Freud.

By Golomb, Jacob

Israel Journal of Psychiatry and Related Sciences, Vol 18(4), 1981, 311-326.

Analyzes 3 attitudes toward the similarities between Nietzsche and Freud. K. Jasper's attempts to purify Nietzsche's image of any connection with Freud were due to Jasper's adherence to the understanding of mental disturbances from a subjective, empathetic viewpoint that conflicted with Freud's mechanistic, deterministic approach. Nazi psychiatrists (including Jung) also wanted to dissociate Freud from Nietzsche because of their antisemitic prejudices. T. Mann, to the contrary, stressed Freud's affinities with Nietzsche because of his attraction toward both thinkers. (35 ref) (PsycINFO Database Record (c) 2016 APA, all rights reserved)

Hi Gilles, I can tell you that we are exploring mainly these links among Freud and Nietzsche's thoughts: Fisrt,  Freud's explanation about a symptom's construction and therefore its interpretation linked to the  Nietzschean notion of force, and second, the closeness among the notions of plurality and over determination.

Hi, you can also explore 2 connected problems: 1/ there is a very important notion: Das es in german: the notion of force: "something" inside us is a force (drive)... You can find this notion in "Ainsi parlait Zarathoustra"... 2/ the subject is divided into several forces, and "thinking" become a very complex activity...

Yes, exactly! This force could be thought as refered to the freudian concept of drive. We are following it in Ecce Homo and Zarathoustra. Thank you.  

Yes, Zarathoustra is a very important text: the body is a set of forces more or less unknown. The subject is fundamentally multiple, complex, divided...  

This point of view is essential for connecting Freud and Nietzsche...
