Passion for Ignorance

The "passion for ignorance" is Lacan's formulation, advanced in Seminar XX, for a structural attitude of the subject toward the being of the Other — specifically, a willed not-knowing that is not mere indifference or simple absence of curiosity, but an active, libidinal investment in remaining unknowing. It is "passion" in the strong, quasi-theological sense: a suffering, an attachment, a mode of jouissance organized around refusal. The subject does not simply fail to know; it wants to know nothing — it positively refuses knowledge of the Other's being, and this refusal is itself a form of knowledge-production, a "supplement" that the subject acquires by keeping the Other's being at bay.

This passion is intimately bound to Lacan's broader thesis in Seminar XX that there is no metalanguage and no sexual relation. Because the Other's being cannot be said — cannot be captured in any signifying articulation — the subject's encounter with it necessarily produces anxiety or dissolution. The passion for ignorance is thus a defensive response to the Real of the Other: rather than confronting the Other's ontological opacity, the subject converts that opacity into a form of jouissance organized around avoidance. Crucially, this is not a neurotic symptom in any simple sense but a structural feature of the speaking being's (parlêtre's) relation to knowledge — the subject always already knows "too much" through lalangue and the unconscious, and the passion for ignorance is the counterforce by which it manages this excess.

In jacques-lacan-seminar-20-cormac-gallagher, the passion for ignorance appears within Lacan's argument that formalisation — topology, the Borromean knot, the matheme — is necessary precisely because the being of the Other cannot be spoken. The concept is therefore positioned as the subjective counterpart to the structural impossibility of metalanguage: if no saying can exhaust the Other's being, the subject's characteristic response is not simply silence but an affective attachment to that silence, a passion. In this way, the passion for ignorance is the lived, libidinal side of what the Borromean Knot writes structurally — the knot's "hole" in the Real corresponds to the subjective enjoyment of refusing to know.

The concept cross-references Knowledge most directly: where savoir is the Symbolic corpus that speaks without knowing itself, the passion for ignorance names the subject's active sabotage of that very circuit, a jouissance-investment in the incompleteness of knowledge rather than an attempt to close it. It equally implicates Jouissance — the "wanting to know nothing" is not neutral; it is pleasurable in the drive-satisfaction sense, a surplus-enjoyment extracted from not-knowing. And it connects to Extimacy: the Other's being is precisely extimate — most intimate yet radically exterior — and the passion for ignorance is how the subject manages the unbearable proximity of that extimate locus. Lalangue provides the medium in which this passion is sedimented: the equivocations and libidinal residues of the mother tongue are the very stuff the subject refuses to interrogate. Taken together, the passion for ignorance is neither pathology nor ignorance in the ordinary sense, but a structural mode of being-in-language that the subject adopts in relation to the Real of the Other.

this additional knowledge, a passion for ignorance; that precisely this is what it wants to know nothing about. About the being of the Other it wants to know nothing.

The phrase "passion for ignorance" is theoretically loaded because it characterizes the not-knowing as an "additional knowledge" — a supplementary savoir that is itself a form of knowing, organized libidinally as desire/drive — and then specifies its precise object as "the being of the Other," which in Lacan's frame is the locus of the Real and of the sexual non-relation, the very thing that topology must write because language cannot say it.
