For analysis not to be an infinite process, for it to find its own internal limit, the analyst's interpretation, which bears upon the signifier, must also reach the real of the symptom, that is, the point where the symbolically non-meaningful latches on to the real…
Lacan introduced a new object in psychoanalysis, the Borromean knot. This knot is both a material object that can be manipulated and a metaphor for the structure of the subject. The knot, made up of three rings, is characterised by how the rings (representing the real, the symbolic, and the imaginary) interlock and support each other. From this point on in Lacan's teaching, the real was no longer an opaque and terrifying unconceptualizable entity. Rather, it is positioned right alongside the symbolic and tied to it by mediation of the imaginary. Thus, whatever our capacity for symbolizing and imagining, there remains an irreducible realm of the non-meaning, and that is where the real is located (see Lacan, 1974-1975). In the final years of his teaching, Lacan took up the question of the symptom and the end of the treatment (1975; 1976). If the symptom is "the most real thing" that subjects possess (1976, p. 41), then how must analysis proceed to aim at the real of the symptom in order to ensure that the symptom does not proliferate in meaningful effects and even to eliminate the symptom? For analysis not to be an infinite process, for it to find its own internal limit, the analyst's interpretation, which bears upon the signifier, must also reach the real of the symptom, that is, the point where the symbolically non-meaningful latches on to the real, where the first signifiers heard by the subject have left their imprint (Lacan, 1985, p. 14). According to Lacan, to reach its endpoint, an analysis must modify the relationship of the subject to the real, which is an irreducible whole in the symbolic from which the subject's fantasy and desire derive. This notion of the real has given rise to numerous misunderstandings. Some have interpreted its resistance to formalization as a slide into irrationality. Others, by identifying the real with trauma, have made it a cause of fear and anxiety. Yet we all have an intuitive experience of the real in such phenomena as the uncanny, anxiety, the non-meaningful, and poetic humour that plays upon words at the expense of meaning. Thus, when the framework of the imaginary wavers and speech is lacking, when reality is no longer organized and pacified by the fantasy screen, the experience of the real emerges in a way that is unique for each person.
