Interminable Interpretation

Interminable Interpretation is a concept Lacan borrows from Peirce's semiotics to name the structural property of signification as an infinite, non-terminating chain. In Peirce's triadic schema, a representamen (sign) points to an object only through an interpretant — but that interpretant is itself a new sign, which in turn requires its own interpretant, and so on without end. Lacan's theoretical move in Seminar 19 is to align this Peircean logic with his own structuralism: the irreducibly triadic nature of the sign — the fact that no dyadic (dual) relation between representamen and object suffices — maps directly onto the Borromean logic of the three registers (RSI), where no pair of rings holds without the third. What is launched by the first separation (the cut that installs the subject in language, what Lacan glosses as "existence is insistence") is not a movement toward a final meaning but an endless relay of interpretation, a chain in which each arrival-point immediately becomes a new point of departure.

The concept thus captures something irreducible in signification: there is no metalanguage, no position outside the chain from which the final meaning could be pronounced. Every "interpreter" — each new reading, each new signifying link — simply opens a fresh iteration. This structural non-closure is not a defect but the very engine of the signifying order. It aligns interminable interpretation with Lacan's broader insistence on the impossibility of a complete Other: the big Other is barred (S(Ø)), meaning is forever deferred, and the subject's desire is perpetually sustained by the gap the chain can never close.

The concept appears once, in jacques-lacan-seminar-19 (p. 171), situated within Lacan's sustained effort to formalize the logic of signification through both topology and imported semiotic frameworks. Its most immediate anchor is the Borromean Knot: Lacan's point is that the Peircean triad (representamen–object–interpretant) instantiates the same irreducible three-way structure that the Borromean rings formalize — no two terms constitute a self-sufficient relation; the third is always required, and it is precisely this third that launches the next iteration of the chain. Interminable Interpretation is therefore a temporal or processual reading of what the Borromean topology describes structurally: the chain in time is what the knot writes in space.

The concept equally presupposes and extends the canonical notions of Signification, Gap, Letter, and Real. The interminability of interpretation is the phenomenology of the gap — the constitutive non-closure that prevents meaning from settling. Every new "interpreter" in the chain is the emergence of a fresh signifier (linked to the Master Signifier's failure to be self-sufficient), and the material trace each link leaves behind is the Letter in the Lacanian sense — the material support that insists through the chain. The horizon that this chain circles but never reaches corresponds to the Real: that which does not cease not to be written, the missed encounter that Repetition endlessly re-stages. Interminable Interpretation is thus not a loose metaphor for "endless meaning" but a precise structural claim: the opening installed by the first separation — "existence is insistence" — is the condition of possibility for the entire chain, and no point in that chain can retroactively suture the originary gap.

the triangle develops in a chain as an interminable interpretation, and the word is from Pierce, all the same it is fantastic 'interminable interpretation', as expression, namely, that every time it is what one could call a new interpreter at every point.

The phrase "a new interpreter at every point" is theoretically loaded because it specifies that the chain is not merely open-ended but structurally self-renewing: each node in the chain is not a passive link but an active "interpreter" — a new instance of the triadic relation — which means closure is not deferred but structurally prohibited. The word "interminable" (borrowed explicitly from Peirce and marked by Lacan as "fantastic") echoes Freud's "Analysis Terminable and Interminable," quietly aligning the logic of the signifying chain with the logic of the analytic process itself: both are constitutively without a final term.
