Two years later==Other Schemata==In addition to [[schema L]] there are several other [[schemata]] that appear in [[Lacan]]'s work ([[schema R]]; schema I;<ref>{{E}} p. 197, Lacan replaces this version 212</ref> the two [[schemata]]of the schema with a newer[[Sade]]<ref>{{Ec}} p.774,778</ref>)

"simplified form' (Figure 15, taken from Ec, 548; see E, 193).  Although schema L allows many possible readings, the main point All of the schema is to demonstrate that the these [[Symbolicschemata]] relation (between the Other and the subject) is always blocked to a certain extent by the [[Imaginary]] axis (between the ego and the SPECULAR IMAGE). Because it has to pass through the [[Imaginary]]  "wall are transformations of language', the discourse of the Other reaches the subject in an interrupted and inverted form (see COMMUNICATION). The schema thus illus- trates the opposition between the basic [[Imaginary]] and the [[Symbolicquaternary]] which is so fundamental to Lacan's conception of psychoanalysis. This is of practical importance in the treatment, since the analyst must usually intervene in the                                 [[Symbolic]] register rather than in the [[Imaginary]]. Thus the schema also shows the position of the analyst in the treatment:  If one wants to position the analyst within this schema of the subject's  speech, one can say that he is somewhere in A. At least he should be. If  he enters into the coupling of the resistance, which is just what he is taught  not to do, then he speaks from a' and he will see himself in the subject.  (S3, 161-2)    By positioning different elements in the four empty loci of the schema, schema L can be used to analyse various sets of relations encountered in psychoanalytic treatment. For example Lacan uses it to analyse the relations between Dora and the other people in her story (S4, 142-3; see Freud, 1905e), and also to analyse the relations between the various people in the case of the young homosexual [[Woman]] (S4, 124-33: see Freud, 1920a).  In addition to providing a map of intersubjective relations, schema L also represents intrasubjective structure (insofar as the one can be distinguished from the other). Thus it illustrates the decentering of the subject, since the subject is not to be located only at the point marked S, but over the whole schema; 'he is stretched over the four corners of the schema' (E, 194).  In addition to schema L there are several other schemata that appear in Lacan's work (schema R - see E, 197; schema I - see E, 212; the two schemata of Sade - see Ec, 774 and Ec, 778). All of these schemata are transformations of the basic quaternary of schema L, on which they are based. However, unlike schema L, which serves as a constant point of reference for Lacan in the period 1954-7, each of these schemata only appears once in Lacan's work. By the time the last of these schemata (the schemata of Sade) appear, in 1962, the schemata have already ceased to play an important part in Lacan's discourse, although it can be argued that they lay the groundwork for Lacan's more rigorous topological work in the 1970s.
