Reminiscence

Reminiscence, as Lacan deploys it in Seminar XV, is not a psychological phenomenon of individual memory-retrieval but a structural figure drawn from Plato's Meno: the theory that learning is in fact anamnesis — the soul's recovery of knowledge it already possessed before birth, rendered visible through Socrates's interrogation of the slave-boy. Lacan borrows this figure not to endorse Platonic metaphysics but to isolate the logical presupposition it encodes: wherever a question about knowledge is posed, there must already be supposed, at the position of the questioner or the questioned, a subject who in some sense already knows. Reminiscence therefore names the mythic-structural operator that backs the "subject supposed to know" — it is the narrative or metaphysical guarantee that knowledge, even when apparently absent or unconscious, was always-already there waiting to be recovered. The Platonic soul's "endless extension" or "duration without limit" is what provides that guarantee: knowledge cannot fail to exist because the soul that bears it is infinite and prior.

This makes Reminiscence, within Lacan's argument, a philosophical symptom as much as a doctrine. The Meno's device of the slave who "rediscovers" geometry through questioning exposes the structural necessity of presupposing a knowing subject — but it does so by positing an immortal, non-lacking soul as the locus of that knowledge. Lacan's critical move is to show that this metaphysical backing is precisely what psychoanalysis cannot accept: the analytic act and the training analysis terminate in désêtre, the fall of the subject supposed to know, not in the triumphant recovery of a pre-existing plenitude. Reminiscence, in sum, is the Platonic solution to the problem of knowledge's origin — and the concept against which the properly analytic account of the subject and knowledge must be defined.

In jacques-lacan-seminar-15-1, Reminiscence occupies a pivotal diagnostic position within Lacan's construction of the sujet supposé savoir. The concept is introduced not as a positive theory of memory but as the metaphysical scaffolding that makes the Subject Supposed to Know seem natural or inevitable: if the soul already contains all knowledge and learning is merely its recovery, then there is always-already a locus of complete knowledge, and the transference fantasy is cosmologically underwritten. Lacan's move is to trace this structural presupposition back to its Platonic origin precisely in order to mark its insufficiency for psychoanalysis. Where Plato's Reminiscence posits a full, timeless soul as the ground of knowledge, the Lacanian account of Knowledge (savoir) insists on constitutive incompleteness — the unconscious is a corpus that "must in no way be conceived as knowledge to be completed, to be closed."

Reminiscence thus stands in a critical, contrastive relation to several cross-referenced canonicals. Against the Subject Supposed to Know, it functions as the mythic prototype: the Meno-slave embodies the pure form of the analysand's transference fantasy — someone who, under questioning, "remembers" what was always already there. Against Knowledge (savoir), it represents the imaginary inverse — a completeable, recoverable totality rather than a constitutively split and non-totalizable articulation. And against the Ethics of Psychoanalysis and The Act, Reminiscence marks the path analysis must not take: the analytic act culminates not in anamnesis but in the fall of the supposed knower, in désêtre, which is structurally incompatible with the Platonic soul's "duration without limit." Reminiscence is therefore a concept the corpus uses to triangulate what is specific and irreducible about the analytic position by naming its most seductive philosophical alternative.

the soul - as it is expressed... does nothing more when it is taught than remember... the idea of an endless extension or rather a duration without limit as regards what is involved in this soul

The phrase "endless extension or rather a duration without limit" is theoretically loaded because it names the metaphysical property — the soul's infinitude across time — that makes the Platonic guarantee of pre-existent knowledge possible; Lacan's entire critical move in Seminar XV depends on showing that this "duration without limit" is precisely what the Lacanian subject, constitutively split and lacking, cannot have, thereby exposing the Subject Supposed to Know as a fiction rather than an ontological fact.
