Jacques Lacan approached psychoanalysis through linguistics and literature. Lacan believed Freud's essential work had been done prior to 1905 and concerned the interpretation of dreams, neurotic symptoms, and slips, which had been based on a revolutionary way of understanding language and its relation to experience and subjectivity, and that ego psychology and object relations theory were based upon misreadings of Freud's work. For Lacan, the determinative dimension of human experience is neither the self (as in ego psychology) nor relations with others (as in object relations theory), but language. Lacan saw desire as more important than need and considered it necessarily ungratifiable.
