A study from the concept of " Subject" in the thought of Jacques Lacan through the Language: the metamorphosis of language or its evolution?

The philosophy of Lacan’s psychoanalysis has affected many of human’s bio-intellectual field under domination of thought. And it has answered many questions about language, speech and unconscious in the form of psychoanalysis discussions. Lacan, French philosopher and psychoanalyst, could have considered the question of the presence of language, speech and the unconscious under the form of the elements like delirium of neurotic patients, paradox of the other, Subject, paternal metaphor, modals, inner desire and desired object in order to find an answer to some of the philosophic psychoanalysis enigmas. The general concepts of Lacan are connected in sequence and are sometimes considered ambiguous. In his idea, the symptoms can be meaningful. These symptoms have a systematic language and complex structure by themselves. On the other hand, the “structure” of Lacan is an intersubjective structure that has to do with a collection of the psychic-hidden facts of the subject. In this study, despite the elements and criteria of structuralism and also with determination of place structuralism, linguistics and psychoanalysis by Lacan, we’ll try to indicate his perception of language, signification and speech in the sequences of “significance” and “sign” and also the role of philosophy in psychoanalysis definition of Lacan.
