Charles Darwin

Charles Darwin is presented as a foundational influence on Sigmund Freud’s scientific outlook and, later, on Freud’s interpretation of human expression. Darwinian evolution helped place human beings within the continuity of nature; Darwin’s account of expressive behavior also offered a model for finding meaning in actions and symptoms once treated as insignificant.

Darwin and Freud’s Scientific Formation

During Freud’s medical education at Vienna University, Darwin’s theories were current and influential. Freud recalled that they attracted him because they promised an extraordinary advance in understanding the world. In his first university year, he attended Carl Claus’s lectures on general biology and Darwinism. Evolution by natural selection, in which species change through conflict without any animating purpose, accorded with the materialist outlook taught by Freud’s principal mentor, Ernst von Brücke, and the Helmholtz school. That school sought to explain organisms through physical and chemical forces rather than occult vital energies.

This intellectual setting mattered to Freud’s early work as a neurologist. He studied nervous systems, first in fish and then in human beings, and investigated subjects including cocaine’s anaesthetic properties, speech disorders, and cerebral paralyses in children. Before psychoanalysis emerged, his research belonged to a reputable, materially grounded science. Darwin’s account of species change reinforced a view in which human beings were part of the natural world rather than exceptions to it.

From Expression to Interpretation

Darwin’s study of emotional expression provided a further bridge to Freud’s work. As Freud later put the idea, bodily sensations and innervations belonged to the field of emotional expression: actions that had originally served a practical purpose could persist in a new role as means of expression. Freud applied this way of thinking to hysterical symptoms, which had previously been regarded as meaningless, and extended the search for significance to dreams, jokes, slips of the tongue, and apparently casual failures of memory.

The resulting interpretive approach made apparently minor or obscure phenomena legible as meaningful formations. Freud did not simply apply Darwin’s biological account unchanged: he carried its attention to the history and function of bodily action into psychological interpretation. His work helped turn symptoms and everyday lapses into material that could be read, while Darwin’s account of expressive behavior supplied an important precedent for treating what appears merely bodily as historically formed and expressive.

Cultural Reach and Limits of the Evidence

The book places this development within a larger change in the humanities. Freud’s extension of interpretation helped make social life available as a kind of text, while Ferdinand de Saussure’s account of language as a system of signs supplied a model for understanding how meanings are constructed and interpreted. Together, these approaches supported the later study of not only art but also gesture, clothing, food, manners, ritual, and social classification. Darwin’s relevance in this account is specific: his explanation of expression helped open a path from bodily action to the interpretation of wider fields of human meaning.

Darwin also appears indirectly in the book’s discussion of the human conflicts Freud associated with childhood and culture. Freud used Sophocles’ Oedipus and Shakespeare’s Hamlet to connect psychic life with major works of literature, arguing that their continuing force depended on conflicts recognizable beyond the characters’ immediate circumstances. These references illustrate Freud’s ambition to show that dreams and psychic life belong to cultural as well as medical inquiry; they do not establish a direct role for Darwin in those literary interpretations. The account therefore presents Darwin above all as a scientific and methodological influence: his evolutionary framework naturalized humanity, and his study of expression helped make meaning in bodily and psychological life an object of inquiry.
