Freud considered Schopenhauer one of the few philosophers who grasped the hidden structure of human behavior long before psychoanalysis took shape. The connection between them lies in how both approached the mind as conflictual, driven by forces outside rational awareness, and shaped by suffering and desire. But Schopenhauer did more than foreshadow psychoanalysis—he provided a philosophical system that allowed Freud to think beyond Enlightenment optimism and the supremacy of reason.

The Will and the human drives

Schopenhauer’s concept of the will—a blind, ceaseless drive manifesting in all living things—helped Freud envision mental life as fundamentally driven by instincts or Triebe. While Freud eventually introduced a dual theory of drives—life (Eros) and death (Thanatos)—the core idea that human beings are motivated by unconscious, irrational forces comes straight from Schopenhauer.

Freud replaced metaphysical will with biologically grounded drives but retained the basic structure of hidden inner forces pushing behavior. Schopenhauer’s work helped legitimize, in Freud’s mind, the possibility of an inner world governed by irrationality. In that sense, Schopenhauer cleared philosophical ground for Freud to introduce a therapeutic science of the unconscious. He did not offer data or treatment, but he shaped the questions. Freud made those questions concrete through clinical experience.

The notion of unconscious motivation appears clearly in Schopenhauer’s writings. He wrote that our actions are often dictated by motives we do not recognize and that reason often comes afterward, offering justifications. Freud transformed that into clinical theory: repression, defense mechanisms, symptom formation. Schopenhauer even stated that people forget painful experiences to protect themselves, a direct precursor to Freud’s ideas on repression and trauma. Schopenhauer lacked empirical methods, but he intuited the psychological cost of internal conflict.

The death drive, introduced by Freud late in his career, also has echoes of Schopenhauer. The idea that organisms possess a drive not only toward life and pleasure but also toward stasis, repetition, and ultimately death, recalls Schopenhauer’s belief that the only escape from the torment of the will is negation—through art, asceticism, or death. Though Freud framed it in dynamic and clinical terms, the resonance is strong.

Sexuality

Schopenhauer’s influence also reached Freud through his emphasis on the centrality of sexuality. For Schopenhauer, sexuality was the purest expression of the will-to-life, and all romantic or idealistic illusions were merely veils over reproductive urges. Freud developed that into a psychological framework that saw sexuality as the foundation of neuroses and personality development. Both thinkers saw civilized behavior as a thin layer over more primitive drives.

Ethics and compassioin

In ethical terms, Schopenhauer’s idea that compassion arises from a direct, non-rational recognition of the other’s suffering paralleled Freud’s later understanding of empathy in therapeutic work. Although Freud did not accept Schopenhauer’s metaphysical pessimism or advocacy of ascetic withdrawal, he respected his ethical realism—the view that suffering is unavoidable and that maturity involves confronting it rather than escaping it.
