Jacques Lacan

Poststructuralist · Europe · 1901 to 1981

French psychoanalyst who held that the unconscious is structured like a language, and that the self is formed through others.

What it is

Jacques Lacan (1901 to 1981) was a French psychoanalyst, trained as a psychiatrist, who became one of the most talked-about thinkers in Paris. He is sometimes called "the French Freud". He set out to reread Freud's discovery of the unconscious, and his ideas became central to how philosophers on the European continent read psychoanalysis.

In the 1930s he finished a doctoral thesis on paranoid psychosis and moved among the Surrealists. Much of his later influence came from the seminars he gave year after year from the 1950s. He argued with the main psychoanalytic body of his day over his methods, dissolved his own school in 1980, and died the next year.

The main ideas

  • The mirror stage. Between about six and eighteen months, a child learns to recognise its own image in a mirror or another reflecting surface. He used this as an account of how the ego forms, and concluded that the ego is an object rather than the free, self-directing "I" it feels like.
  • Three registers. He sorted experience into the Imaginary (the images through which we see ourselves and others), the Symbolic (language, rules, laws and customs) and the Real (what escapes both and cannot be put into words).
  • A language of the unconscious. One of his best-known claims is that the unconscious is structured like a language.
  • Need, demand and desire. Needs are bodily, and a baby cannot meet them alone. Others read its cries as demands and teach it to ask in the terms of the social world. Desire, in his account, is restless: no object it reaches is ever quite the thing it was after.
  • Drive and enjoyment. He reworked Freud's theory of drives and used the French word jouissance, usually left untranslated, for a kind of enjoyment that goes beyond simple pleasure.
  • Return to Freud. He urged a close reading of Freud's own texts and criticised the ego psychology that had grown out of them, which tried to strengthen the patient's ego.

What it looks like in practice

Think of a time when the picture you had of yourself, in a photo or on a screen, did not match how you felt inside. Lacan would not treat that gap as a mistake to fix. He would say that the ego is built partly from images of this kind, and that it is not the whole of who you are. This is an illustration of his line of questioning, not a passage from his writing.

Books and moments

  • His doctoral thesis on paranoid psychosis (1932) is his first major work.
  • The Seminars, given year by year from the 1950s until 1980, are where most of his teaching took place.

Questions and criticism

  • A hard writer. His terms shift from year to year and even careful readers disagree about what they mean.
  • Methods and orthodoxy. His sessions of variable length, and his criticism of established psychoanalysis, brought him into conflict with the main professional body, which set conditions on his society in 1963.
  • What can be tested? It is fair to ask how claims such as the three registers could be checked by evidence, or whether they are best read as a way of seeing.

Close neighbours

Sigmund Freud is the thinker Lacan set out to reread, and Ferdinand de Saussure supplied the linguistics behind his idea of the Symbolic. The pages on Jacques Derrida and Michel Foucault show two other French thinkers working on language and the self at the same time.
