Non-Knowledge

Non-Knowledge (le non-savoir) is a term that Lacan invokes in Seminar XIX in order to delimit and contest a rival orientation within the psychoanalytic field — one that would elevate ignorance to a positive theoretical banner. The reference point is Georges Bataille's lecture on non-knowledge, in which not-knowing is valorized as an ecstatic, sovereign experience that escapes the calculative logic of knowledge. Lacan's move is polemical: he acknowledges the term as a real theoretical event but refuses its appropriation as a legitimating slogan for what he regards as an opportunistic misreading of his own work. Specifically, certain institutional actors, prompted by Lacan's introduction of the Saussurean concept of lalangue, launched the Vocabulaire de la Psychanalyse — an encyclopedic project that, in Lacan's view, reduces the linguistic dimension of the unconscious to a dictionary (a closed lexicon) rather than grasping it as grammar, logic, and structural repetition (automaton).

In this context, non-knowledge functions as a polemical foil: it names the gesture of treating the analyst's constitutive non-mastery as a positive epistemic programme, thereby obscuring that psychoanalysis is, for Lacan, fundamentally a matter of savoir — the knowledge that speaks without knowing itself, the symbolic corpus of the unconscious. The analyst's ignorance (ne pas savoir) is better understood, in Lacan's own terms, as a passion structurally tied to the position of objet petit a in the Discourse of the Analyst, not as the suspension or negation of knowledge. Non-knowledge as a flag misnames this structural condition by romanticizing it, and in doing so colludes with the very dictionary-logic (lalangue-as-lexicon) that erases the difference between language-as-structure and lalangue-as-jouissance.

This concept appears in jacques-lacan-seminar-19a (p. 7) and occupies a precise polemical moment within Lacan's late effort to clarify what it means to say "the unconscious is structured like a language." By this stage in his teaching, Lacan is actively distinguishing lalangue (the jouissance-saturated, idiomatic, non-systemic materiality of the mother tongue) from language (the structured, differential system), and insisting that the unconscious is composed of the former but organized by the logical — not merely linguistic — operations of the latter. Non-knowledge is invoked as the wrong conclusion to draw from this distinction: as if, because lalangue overflows grammar and formal structure, the analytic position must be one of principled ignorance.

Against this reading, Lacan anchors the analyst's position in Knowledge (savoir) — specifically the unconscious savoir qui ne se sait pas that operates through the signifying chain. The Automaton — the dimension of signifying repetition, the mechanical return of the symbolic — is precisely what governs the logic Lacan defends; it is not dissolved by non-knowledge but is its structural counter. The Discourse of the Analyst, in which objet petit a occupies the agent position and savoir occupies the place of truth, further clarifies why the analyst's non-mastery is not non-knowledge: knowledge appears in the place of truth, structurally present even when invisible from the surface. Non-knowledge, as a concept, thus serves in Seminar XIX as a boundary marker: it names what psychoanalytic practice is not, precisely in order to defend what savoir, lalangue, automaton, and the analyst's discourse properly designate.

there is non-knowledge (le non-savoir). I should say that Georges Bataille gave a lecture on non-knowledge...And I will come back to it later. But when those responsible...were launched on the Vocabulaire de la Psychanalyse, it is obviously because I had put on the agenda the Saussurian term lalangue.

The quote is theoretically loaded because it juxtaposes two moves simultaneously: it acknowledges le non-savoir as a legitimate intellectual event (Bataille's lecture) while immediately linking the institutional uptake of that concept to a misreading of lalangue — specifically, the reduction of Lacan's Saussurean intervention to a dictionary project (Vocabulaire de la Psychanalyse). The word "obviously" (évidemment) signals Lacan's sardonic claim that the connection between promoting non-knowledge and misappropriating lalangue is transparent to him, positioning non-knowledge not as a neutral alternative but as a symptomatic response to — and evasion of — the structural logic his own work introduces.
