Point de capiton
|French: point de capiton|
The French term point de capiton is variously translated in English editions of Lacan's work as "quilting point" or "anchoring point." To avoid the confusion resulting from this variety of translation, the term has here been left in the original French.
It literally designates an upholstery button, the analogy being that just as upholstery buttons are places where "the mattress-maker's needle has worked hard to prevent a shapeless mass of stuffing from moving too freely about.<ref>Bowie, Malcolm. (1991) Lacan, London: Fontana. p.74</ref>," so the points de capiton are points at which the "signified and signifier are knotted together."<ref>Lacan, Jacques. The Seminar. Book III. The Psychoses, 1955-56. Trans. Russell Grigg. London: Routledge, 1993. p. 268</ref>
Lacan introduces the term in his 1955-6 seminar on the psychoses to account for the fact that despite the continual slippage of the signified under the signifier, there are nevertheless in the normal (neurotic) subject certain fundamental "attachment points" between the signified and the signifier where this slippage is temporarily halted. A certain minimum number of these points are "necessary for a person to be called normal," and "when they are not established, or when they give way'" the result is psychosis.<ref>Lacan, Jacques. The Seminar. Book III. The Psychoses, 1955-56. Trans. Russell Grigg. London: Routledge, 1993. pp. 268-9</ref> This helps to explain how it is that in the psychotic experience, "the signifier and the signified present themselves in a completely divided form."<ref>Lacan, Jacques. The Seminar. Book III. The Psychoses, 1955-56. Trans. Russell Grigg. London: Routledge, 1993. p. 268</ref>.
Illusion of a Fixed Meaning
The point de capiton is thus the point in the signifying chain at which "the signifier stops the otherwise endless movement of the signification" and produces the necessary illusion of a fixed meaning.<ref>Lacan, Jacques. Écrits: A Selection. Trans. Alan Sheridan. London: Tavistock Publications, 1977. p. 303</ref>
Diachronic and Synchronic Dimension
The diachronic dimension of the point de capiton lies in the fact that communication is always a retroactive effect of punctuation. It is only when the sentence is completed that the sense of the first words is determined retroactively. This function is illustrated in the elementary cell of the graph of desire, in which the point de capiton is the leftmost point of intersection between the vector S - S' and the vector.
"The synchronic structure (of the point de capiton) is more hidden, and it is this structure that takes us to the source. It is metaphor."<ref>Lacan, Jacques. Écrits: A Selection. Trans. Alan Sheridan. London: Tavistock Publications, 1977. p.303</ref>
