Sigmund Freud

Neurologist and founder of psychoanalysis · 1856–1939

Sigmund Freud was an Austrian neurologist who founded psychoanalysis — the first systematic method of exploring the unconscious mind. His discovery of repression, the Oedipus complex, and the tripartite structure of id, ego, and superego established the conceptual ground from which all subsequent depth psychology emerged. His break with Jung in 1912 catalyzed analytical psychology as a distinct tradition.

What Did Freud Discover About the Unconscious?

Before Freud, the unconscious was a philosophical intuition. After Freud, it was a clinical reality. In The Interpretation of Dreams, published in 1900, Freud established that dreams are not random noise but structured communications from a repressed interior — that the psyche has a hidden life with its own logic, its own grammar, and its own demands (Freud, 1900). This was a rupture in Western self-understanding. The rational subject of the Enlightenment now had a basement, and Freud was the first to descend into it systematically.

His structural model — id, ego, and superego — as formulated in The Ego and the Id, gave psychology its first architecture of the inner world (Freud, 1923). The id as the seat of instinctual drives, the superego as internalized authority, and the ego as the mediating agency between them: this tripartite map, whatever its limitations, remains the template against which every subsequent model of the psyche has positioned itself. The mechanism of repression, the concept of transference, the method of free association — these were not merely therapeutic techniques but epistemological breakthroughs. They demonstrated that the psyche conceals as much as it reveals, and that what is concealed exerts force.

Why Does Freud Matter for the Jungian Tradition?

Freud matters to depth psychology not only for what he built but for what his limitations provoked. Jung’s break with Freud in 1912 — recounted with gravity in Memories, Dreams, Reflections — was a disagreement about the nature of libido itself (Jung, 1963). For Freud, libido was fundamentally sexual. For Jung, it was psychic energy in a far broader sense, capable of symbolic and spiritual expression. The split was generative: it forced Jung to develop his own framework — archetypes, the collective unconscious, individuation — precisely because Freud’s reductive model could not account for what Jung was encountering in his patients and in himself.

Convergence psychology, as explored across the work gathered at Seba.Health, inherits from both sides of this rupture. Freud opened the descent; Jung mapped the territory below.
