Jacques Lacan

Lacan trained as a psychiatrist before turning to psychoanalysis, and spent his career insisting that Freud had been fundamentally misread by an analytic establishment more interested in adjusting patients to social norms than in confronting the genuinely strange structure Freud had actually discovered. His mirror stage describes an infant, still uncoordinated and fragmented in its actual bodily experience, encountering its reflection and seizing on the image as a coherent, unified self: a moment of identification Lacan considered a kind of founding misrecognition, since the wholeness the child sees belongs to the image, not to the child's felt experience of its own body, and this gap between the image we identify with and the fragmented reality underneath never fully closes. He proposed that the unconscious is structured like a language, governed by the same mechanisms of substitution and displacement that linguists like Saussure had identified in ordinary speech, so that psychoanalysis was, properly understood, an interpretive practice much closer to reading a text than to medical diagnosis. His famous 'return to Freud' was simultaneously a return and a radical reinvention, developing a notoriously difficult technical vocabulary (the Symbolic, the Imaginary, the Real, objet petit a) that many found either revelatory or willfully obscure, sometimes both. He held influential public seminars in Paris for over two decades that drew philosophers, artists, and analysts across disciplines, was formally expelled from the International Psychoanalytical Association over his unorthodox and often very short training-analysis sessions, and founded his own school to continue his work outside institutions he considered to have betrayed Freud's original insight.
