Perhaps the most controversial subject in the Lacanian poststructuralist psychoanalytic theory is his concept of the unconscious. Jacques Lacan has been hailed as a French psychoanalyist whose work has exerted an immense influence upon varied aspects of contemporary theory including feminism and film studies. Lacan has formulated his theories based on Freudian Unconscious and his tripartite model of the mind (id, ego and super-ego with its desires, conflicts and repression. He has elaborated Freud's theories while drawing on perspectives informed by Saussurean Structural Linguistics. This paper is an effort to trace out the concept of the Freudian unconscious and to attempt a critique of Lacan's well known and often quizzical declaration that the unconscious is structured like a language. Apparently this definition runs counter to Freud's idea of the unconscious Lacan's idea of the unconscious cannot be studied and evaluated without the Freudian context
