Friedrich Nietzsche’s Essay “On the Genealogy of Morality” (1887): The birth of morality as a reaction to the struggle for existence

Introduction: The concept of “unheimliche” as a return of the repressed childhood horror

Friedrich Nietzsche’s essay “On the Genealogy of Morality” (“Zur Genealogie der Moral”, 1887) represents not just a literary and psychological analysis, but a foundational work on the aesthetics and psychology of fear, where E.T.A. Hoffmann’s Christmas tale “The Sandman” becomes a key clinical and cultural example. Nietzsche uses this novella to illustrate his thesis that the “unheimliche” is not something fundamentally new or alien, but a return of a long-known, but repressed childhood experience, often associated with trauma. In this context, Christmas serves not as a celebration, but as a chronological marker, fixing the moment of a psychological catastrophe.

The concept of “unheimliche”: Linguistic and psychoanalytic analysis

Nietzsche begins with a linguistic analysis of the German word unheimlich (frightening, eerie). He shows that its antonym heimlich means not only “domestic, cozy”, but also “hidden, secret”. Thus, unheimlich is not just “not-domestic”, but something that should have remained hidden, but has emerged. This semantic field leads to the psychoanalytic core: the unheimliche is that which was once heimlich, familiar, part of the “home” of the psyche (such as childhood fears, complexes), but was repressed, and now returns in an altered, alien form, causing anxiety.

Hoffmann’s “The Sandman” as a model of Christmas trauma

Nietzsche analyzes Hoffmann’s novella in detail, highlighting the structuring elements of neurosis.

Christmas as the scene of the initial trauma: The climax of the little Nathanial’s childhood fears occurs exactly on Christmas Eve. He, waiting for gifts, spies on his father and the sinister lawyer Koppelyus (a prototype of the Sandman — a mythical creature throwing sand in the eyes of children to make them fall asleep). The boy witnesses a terrifying alchemical experiment associated with violence against the eyes. The gift-giving festival turns into a scene of anxiety and horror before the father figure, split into a good father and the evil Koppelyus.

The threat of the Sandman’s “take out the eyes” becomes the core of the phobia. In this way, the Christmas gift is forever associated with the threat of loss, not with receiving.

Compulsive repetition and splitting of the father’s image: The trauma received on the night of Christmas defines Nathanial’s entire life. In adulthood, he encounters two characters in which the traits of Koppelyus are projected: the optician Giuseppe Coppolo and the professor Spalanzani. This compulsive repetition is a classic neurotic mechanism, where the psyche unconsciously reproduces the traumatic situation, trying to “replay” it.

The doll Olympia as the “unheimliche” revival of the inanimate: Nathanial’s fascination with the automaton Olympia is a central episode for Nietzsche. The unheimliche here arises from the ambiguity between the living and the inanimate. Olympia seems alive, but is a mechanism. This ambiguity touches on a deep infantile conflict: children often animate dolls, but also experience fear of them. The animated doll is the return of animistic beliefs from childhood, which the civilized adult has long discarded.

Christmas trauma in the light of the theory of neurosis

Nietzsche, analyzing Hoffmann, actually constructs an etiological model of obsessional neurosis:

Traumatic event: The scene on Christmas Eve.

Repression: Childhood fears and affects are pushed into the unconscious.

Return of the repressed in an “unheimliche” form: In adult life through phobias (fear of the Sandman/opticians), obsessional actions and objects (doll Olympia).

Symbolic association. The festival becomes a conditional reflex, a trigger that activates anxiety.

Thus, Nietzsche shows how a single, but intense experience, attached to a calendar holiday, can become an organizing principle of the entire psychic life, deforming reality through the lens of childhood horror.

Critique and expansion of the Freudian interpretation

Although Freud’s interpretation has become canonical, modern researchers see broader meanings in “The Sandman” and beyond:

Critique of scientific rationalism: Hoffmann, and with him Freud, question the boundary between the living and the mechanical, which is especially relevant in the age of the industrial revolution and the emerging artificial intelligence. Fear of the automaton is also fear of losing one’s human essence.

Trauma as a violation of privacy and trust: Nathanial becomes a witness to the secret, “adult” and violent world of the father. The Christmas idyll is destroyed by the intrusion of the real father-demiurge, creating violence. This is a trauma of revelation and the loss of a safe childhood world.

The “unheimliche” in the digital age: Freud’s concept has proven to be incredibly relevant for analyzing modern culture. The phenomenon of the “uncanny valley” in robotics and CGI is a direct continuation of the idea of fear of the almost living, but not quite human. Social networks full of “revived” images from the past and deepfake are a fertile ground for a new type of unheimliche.

Interesting fact: According to testimonies, Nietzsche himself experienced intense anxiety on the eve of Christmas, which some biographers link to his complex relationship with his father and possibly his own unconscious associations, which he so brilliantly described.

The significance of the essay for understanding festive psychology

Nietzsche’s work takes the analysis of festivals beyond sociology and cultural studies into the field of clinical psychology of individual experience. It shows that:

Festivals, especially those emotionally intense, such as Christmas, are powerful magnets for projections of childhood conflicts.

Nostalgia and anxiety often accompanying festivals may not just be “atmosphere”, but an active return of the repressed.

Trauma tied to a calendar date acquires special persistence, as the annual cultural context (decorations, rituals, expectations) reactivates neural networks associated with the original experience.

Conclusion: Christmas as an eternal return of the repressed

Nietzsche’s essay “The Unheimliche” turns Hoffmann’s Christmas tale into a universal paradigm for understanding psychic trauma. It demonstrates how a festival, intended to be the most heimlich (domestic, cozy), can become a catalyst for the most unheimliche (frightening) experience — the encounter with one’s own repressed childhood horror.

Freud’s analysis teaches that neurosis often has not an abstract, but a calendrical-mythological architecture. Trauma, like a festival, repeats, compulsively returning in the form of symptoms. “The Sandman” becomes, thus, not just a terrifying fairy tale, but an allegory of the work of the unconscious, where the Christmas tree casts not only cozy light, but also long, distorted shadows of repressed memories. In this sense, every festival is a potential encounter with one’s own “Sandman”, with what we once hid in the farthest corner of the psyche, but what continues to live its autonomous, terrifying life, ready to emerge at the moment when we most expect peace and joy.
