There could be metaphor without previous metonymy. Of a preliminary issue to all possible psychosis treatment Lacan formulates the metaphor follows: S. S? S 1 S x s x designates the place of the phallus as a sign of the significant passion. I.e. the x introduces the subject to come at level mystery against the desire of the other, whose motion, establishes it in the place of the phallus. In relation to the scheme (II) locate the s in the place as in the algorithm is given the meaning and where S is the combination and significant substitution product, the meaning is presented as a fact of the signifier of whose existence may not realize but as production of the operations carried out at a significant level. In the signification of the phallus Lacan says that Freud, in his time, had not only anticipated the formulas of the Linguistics, but which had also given to the relationship between their terms effective range that should understand them, this is: the active function of the signifier of the meaning. If the terms linguistics of his time possessed no faltaron Freud, Lacan is not without the concepts of current linguistics that Freud was already used.
In other words: if Lacan is Freudian language is still at level terminological Lacan Freud. A coincidence of reading that makes Lacan of the sign of Saussure, which carries out Freud of his predecessors in the study of the oneiric is revealed in the interpretation of dreams: in the introduction to this study refers to different methods. The first is the symbolic method, which consists in replacing the contents of a dream by another analogous. The second called by method decryptor, on the basis of this procedure, each sign can be replaced by using a preset key. Idt energy will not settle for partial explanations. The third method is a variant of the second: settle differences in what can represent every sign of an oneiric element, according to the social condition of the cash, depending on both the second and the third method, a key book or book of dreams.
