For Lacan the fundamental problem is that of the subject's relation to language. However, taking into account the Real - from the trilogy of the Symbolic, the Imaginary and the Real - modifies the situation. Previously, the crucial issues were the rapports between identification, transference and demand; now the queston "will entail the holding out of a form, of an essential topology for analytic praxis." The signifier returns as structured on the Moebius strip with three forms of the hole, the torus or ring, the cross-cap, and Euler's circles as the maze of the torus or of the spiral of the demand on the surface of the Klein bottle. These figure though constructed in a simple and combinatory way, are nevertheless complicated to comment.
