What happens to an analysis when bodies lose sight of each other and only the hallucinatory virtue of representation ensures their existence? This question brings us back to a central issue in settings that essentially involve speech, when we are interested in the action and effects of its incarnation in the dialectic of presence and absence. This shows the importance of the flesh and therefore of the analyst’s body, upon which violent demands are sometimes made when identity seesaws, when words fail, crushed by the force of madness: such phenomena are familiar, of course, in the analysis of psychotic moments or patients, but are intensely activated whenever the subject’s self-intimacy is eclipsed or threatened with disappearance. The incarnation in the transference - and not the embodiment of the transference - performs a decisive function, because it can prove to be dangerous, whenever the boundaries are porous, or whenever the mixture haunts the analysis.
