L Schema

ELI5

Imagine two conversations happening at once: one real, deep conversation between your unconscious and the Other (like language, culture, or a parent), and a second, noisier conversation between your ego and what you see in the mirror. The L Schema is Lacan's diagram showing how that noisy ego-conversation keeps interrupting and drowning out the deeper one.

Definition

The L Schema (also called the Z-schema, Z-shaped diagram, or "little square") is Lacan's foundational topological formalization of the four-term structure of subjectivity, introduced around 1955 and appearing across Seminars I–VIII and the Écrits. It maps four positions arranged in a quadrilateral or "Z" shape: S (the subject, or Es/Id — the speaking being beyond the ego), A (the big Other — the unconscious as symbolic order, locus of the signifier), a (the ego — imaginary self), and a' (the little other — the specular alter-ego). Two axes cross: the symbolic axis runs diagonally from S to A, representing the fundamental discourse of the unconscious; the imaginary axis runs from a to a', representing the alienated, specular relation between ego and its mirror image. The critical structural point is that the imaginary axis cuts across and interferes with the symbolic axis — the ego-to-other relation repressively covers over the subject's relation to the Other, causing the fundamental discourse to be misrecognized, intercepted, and distorted.

The schema is explicitly not a spatial diagram in the intuitive sense but a topological one: its terms denote positions or loci and their structural relations (interposition, crossing, succession), not locations. It formalizes several key Lacanian claims simultaneously: that the unconscious is the Other's discourse; that the subject receives its own message back from the Other in inverted form; that the analytic situation is four-positional rather than dyadic (two subjects, each with both an ego and a subjectivity beyond the ego); that the analyst's proper position is at A (the Other), not at a' (the imaginary alter-ego); and that psychosis, neurosis, and perversion can each be mapped onto the schema by specifying which vector is interrupted or foreclosed. The schema also serves as the generative precursor to Schema R (which expands it into a full trapezoid incorporating the phallus, Mother, Ego Ideal, and Father), and to the Graph of Desire.

Evolution

The L Schema first appears in 1955 (according to Darian Leader, cited in the corpus), concurrent with Seminar II and Seminar III. In its earliest articulation (Seminar I–II, return-to-freud period), the schema is presented as A.m.a.S — four poles mapping the radical Other (A), the ego (m), the little other (a), and the subject (S). Its clinical work in this period is primarily to distinguish repetition (the fundamental discourse running A→S) from transference (which happens along the imaginary m–a axis), and to diagnose what goes wrong when ego psychology collapses these two into a single dyadic relation. The schema is reflexively acknowledged even here as "metaphorical, analogical" — its value is heuristic and topological, not pictorial (Seminar II, p. 257).

In Seminar III (return-to-freud), the schema is consolidated as the formal framework for theorizing psychosis: the interruption of full speech between S and O by the imaginary circuit (o and o') is mapped directly onto verbal hallucination and the breakdown of the symbolic order in Schreber's case. In Seminars IV and V (still return-to-freud), the schema is deployed extensively against object-relations theory (Marty, Fain, Bouvet): the S–A symbolic axis must not be collapsed into the a–a' imaginary axis. Here too the schema generates Schema R by "closing" its indirect paths into a quadrangle incorporating the phallus, Mother, and Ego Ideal (Seminars IV and XIII).

By the Écrits ("On a Question," "Direction of the Treatment," "The Freudian Thing," "Seminar on 'The Purloined Letter'"), the schema is explicitly named "Schema L" and linked to the position of the analyst as Other, the constitution of desire, and the return of the subject's message from the Other. In Seminar VI (return-to-freud/structuralist transition), the fantasy formula (S◇a) is shown to encode the same structural relation as Schema L's quadrilateral. In Seminar XIII (object-a period), Lacan retrospectively situates Schema L as the first in a genealogy of oriented networks (L → R → Graph → topological surfaces), and in Seminar XVIII (discourses period) he cautions that the written schema, extracted from speech, becomes a site of misunderstanding — a self-critical note about the limits of formalization itself.

Secondary commentators extend and differentiate the schema's application. Boothby (Freud as Philosopher) positions Schema L as the schema specifically of the neurotic/analytic situation, and Schema R as its fuller successor that incorporates symbolic castration. Fink (The Lacanian Subject) retranscribes Schema L as "Chain L" using parenthetical/binary notation to show that object a as cause is structurally latent within the original formalism. Both moves testify to the schema's status as a theoretical generative matrix rather than a static diagram.

Key formulations

Reading Lacan's Écrits: From 'The Freudian Thing' to 'Remarks on Daniel Lagache'Derek Hook, Calum Neill & Stijn Vanheule (eds.) · 2019 (page unknown)

The entirety of this section relies upon one of Lacan's visual formalizations: the 'L-schema'… four positions are represented… '(Es) S'… 'a′ other'… '(ego) a'… 'A Other'

This is the most complete single-passage enumeration of the four poles of the L Schema in the corpus, giving both the labels and their structural roles (Es/subjectivity, ego, alter-ego, symbolic unconscious) and explicitly naming the Imaginary and Symbolic axes.

Seminar V · Formations of the UnconsciousJacques Lacan · 1957 (p.489)

Schema L [see Ecrits, p. 53] is intended precisely to indicate that the question is whether, along the vector that goes from the Other to the subject, there is anything that traverses this imaginary relationship or not.

This formulation captures the schema's core clinical-theoretical purpose: to ask whether the symbolic vector (A→S) can cross through the imaginary interposition (a–a'), making explicit the schema's diagnostic function for analytic technique.

Seminar III · The PsychosesJacques Lacan · 1955 (p.27)

Our schema, I remind you, represents the interruption of full speech between the subject and the Other and its detour through the two egos, о and o,' and their imaginary relations.

This is Lacan's own concise gloss of the schema in clinical context, emphasizing the structural role of the imaginary detour in blocking the subject–Other relation, and anchoring the schema's use in the theory of psychosis.

Reading Lacan's Écrits: From 'The Freudian Thing' to 'Remarks on Daniel Lagache'Derek Hook, Calum Neill & Stijn Vanheule (eds.) · 2019 (page unknown)

the subject's speech is, in the first place, a message for himself returning from the place of the Other (as formalized in the L-schema).

Succinctly encapsulates the schema's account of how language works: the subject's own message is constituted and returned from the position of the symbolic Other, not generated by the ego — making the schema fundamental to the theory of speech and demand.

Seminar XIII · The Object of Psychoanalysis (alt. translation)Jacques Lacan · 1965 (p.253)

it is not today or yesterday, of course, that I tried to form this construction, these networks, these written indicators, these orientated networks that are called successively Schema L or Schema R or the Graph

Lacan's own late retrospective positioning of Schema L as the inaugural formalism in a genealogy of oriented networks — L, R, Graph, topological surfaces — locating the schema's historical place in his theoretical development.

The chess knight's move as metaphor for the imaginary axis of the L Schema (literature)

Cited by Reading Lacan's Écrits: From 'The Freudian Thing' to 'Remarks on Daniel Lagache'Derek Hook, Calum Neill & Stijn Vanheule (eds.) · 2019 (page unknown). Fink (in Lacan 1966/2006a: 803) maps the chess knight's move (cavalier) onto the ego-to-other vector of the L Schema's imaginary axis. The obsessive's 'switching of knights' corresponds to the movement along the a–a' axis, while the hysteric's 'step' (the queen's move) enacts the subject's attempt to traverse the imaginary impasse. The chess metaphor spatialises the schema's axis structure and connects it to the Saussurean synchronic/diachronic distinction.

Schreber's verbal hallucination and the L Schema (case_study)

Cited by Seminar III · The PsychosesJacques Lacan · 1955 (p.27). Lacan deploys the L Schema in Seminar III to map the structure of verbal hallucination in Schreber's psychosis. In psychosis, the subject becomes completely identified with his ego, and what should be a third-person subject (S) speaking through the ego collapses into a dual relation — the imaginary axis takes over entirely, and the Other (A) is no longer accessible. The schema thus explains why hallucinated voices 'speak of' the subject rather than 'to' him.

Velázquez's Las Meninas as a structural illustration of the L Schema's subject-mirror-Other arrangement (art)

Cited by Seminar XIII · The Object of PsychoanalysisJacques Lacan · 1965 (p.236). Lacan reads Las Meninas as enacting the structural arrangement of the L Schema: the invisible royal couple in the mirror occupy the position of the big Other, while the painter, the Infanta, and the ladies-in-waiting constitute the imaginary and specular field. The painting functions as a 'trap for the look' rather than a representation, mapping how the gaze of the Other (A) organizes the specular field (a–a') without being directly visible within it.

The case of the young homosexual woman (Freud) mapped onto the L Schema (case_study)

Cited by Seminar IV · The Object RelationJacques Lacan · 1956 (p.125). Lacan uses the L Schema to analyze the structural permutation in Freud's case: after the father gives a child to the mother (a real intrusion of the symbolic into the imaginary plane), the young woman shifts her position on the schema — the father moves from the big Other (A) to the level of the ego (a), and she takes the male position, placing the 'lady' at a'. This reading demonstrates the schema's capacity to track structural re-positioning across the imaginary and symbolic axes.

Leonardo da Vinci's mirror writing as a symptom of imaginary over-investment in the L Schema (art)

Cited by Seminar IV · The Object RelationJacques Lacan · 1956 (p.425). Lacan inscribes Leonardo's 'inversion' (mirror writing, sublimation, and atypical sexual maturation) onto the L Schema diagram, labelling the diagram 'Leonardo's inversion.' The schema shows how Leonardo's radical self-alienation in the imaginary — a structural necessity of his subjective position — manifests in his creative work as a de-subjectification that paradoxically enables exceptional sublimation.

Tensions

Within the corpus

Whether Schema L is the primary, sufficient diagram for formalizing the analytic situation, or whether it is only a limited/failed case that must be superseded by Schema R.

Lacan (Seminars II–VI, Écrits) presents Schema L as the comprehensive formal model of the analytic situation, articulating the symbolic and imaginary axes that structure subject-Other relations, transference, and the direction of treatment. It is deployed as the definitive counter-model to dyadic ego psychology. — cite: derek-hook-calum-neill-stijn-vanheule-reading-lacan-s-ecrits-from-the-freudian-t p. 212
Boothby argues that Schema L 'is rightly interpreted as the schema of the analytic situation' only in a limiting, neurotic sense — it maps the specific inflection where the ego over-invests the imaginary at the expense of symbolic mediation. Schema R is the fuller picture, because only it incorporates the real (das Ding, maternal Thing) and the action of symbolic castration that differentiates the imaginary axis from the symbolically mediated ego ideal axis. — cite: richard-boothby-freud-as-philosopher-metapsychology-after-lacan-routledge-2001 p. 271

This tension bears on whether Schema L is theoretically complete or is itself a symptom of the neurotic perspective it describes.

Whether the written formalization of Schema L clarifies or obstructs theoretical understanding.

Lacan (Seminars II–VI, 'On a Question') consistently presents Schema L as a necessary and clarifying formal model — a topological diagram that makes visible the crossing of symbolic and imaginary axes, corrects imaginary-centric readings, and enables clinical orientation. It is introduced as the formal counter to Fairbairn's object-relational schemas and ego-psychological dyadism. — cite: jacques-lacan-seminar-4 p. 9
Lacan himself (Seminar XVIII, discourses period) warns that 'the written taken up all by itself, whether it is a matter of one or other schema, the one that is called L or any other one whatsoever, or the big graph itself, presents an opportunity for all sorts of misunderstandings.' The graphs are only understandable through the style of the Écrits as their steps; those who start directly from the graphs misread them. — cite: jacques-lacan-seminar-18 p. 62

This is a self-critical tension within Lacan's own corpus: early Lacan deploys Schema L as a clarifying tool; late Lacan flags it as a potential site of misunderstanding when detached from speech.

Across frameworks

vs Ego Psychology

Lacanian: The L Schema is Lacan's direct theoretical weapon against ego psychology. The schema insists that the analytic situation is constitutively four-positional: S (subject as unconscious), A (Other as symbolic order), a (ego), and a' (analyst's ego or imaginary alter-ego). The analyst must occupy the position of A (Other), not a' (imaginary alter-ego). To orient analysis toward ego-strengthening or mutual adaptation is to reduce it to the imaginary a–a' axis, foreclosing the symbolic S–A axis where the unconscious speaks. For Lacan, 'Wo Es war, soll Ich werden' is systematically misread by ego psychology as a mandate to reinforce consciousness over the id.

Ego Psychology: Ego psychology (Hartmann, Kris, Loewenstein) holds that the therapeutic aim of analysis is the strengthening and autonomy of the conflict-free ego sphere. The analyst's mature ego serves as a model for identification; the analytic relationship is essentially dyadic — a two-person process in which the analyst's well-analyzed ego provides a corrective object relationship. The analyst's countertransference, including emotional response, is a resource to be managed in service of helping the patient achieve better adaptation to reality.

Fault line: The central fault line is whether the analytic relationship is fundamentally dyadic (ego–ego) or quadripartite (subject–Other traversing through imaginary). Ego psychology naturalizes the imaginary axis; Lacanian theory insists the imaginary axis is the obstacle, not the vehicle, of analytic transformation.

vs Object Oriented Ontology

Lacanian: The L Schema positions all four terms — S, A, a, a' — as relational positions within a signifying structure, not as autonomous objects. The subject (S) is constitutively barred, lacking any self-sufficient ontological status; its being is eccentric to itself, located in the Other's discourse. The 'object' (little a) is not a thing with intrinsic properties but an effect of the subject's desire, a structural remainder of the symbolic chain. For Lacan, there is no flat ontology of objects: the asymmetry between the symbolic Other and the imaginary other is irreducible.

Object Oriented Ontology: Object-Oriented Ontology (Harman, Bryant) insists on the equal ontological status of all objects — human and non-human, real and fictional — and their irreducibility to relations or subject-correlates. Objects withdraw from all relations and from each other; no relation exhausts an object's being. OOO would resist the Lacanian priority given to the signifying chain and the big Other as constitutive of subjectivity, viewing this as a form of linguo-centrism that subordinates things to human symbolic frameworks.

Fault line: Lacan's schema is relational and asymmetric (the symbolic axis is primary; the subject is constituted by the Other's signifiers); OOO is non-relational and flat (objects precede and exceed all their relations). The very notion of a 'big Other' that constitutes the subject would be incoherent from an OOO standpoint.

vs Humanistic Self Actualization

Lacanian: The L Schema formalizes why self-actualization in the humanist sense is structurally impossible for the Lacanian subject. The subject (S) is constitutively split — its 'message' returns from the place of the Other (A) in inverted form, meaning the subject never has direct access to an authentic inner core that could be 'actualized.' The imaginary ego (a) is precisely an alienated formation, a misrecognition. The direction of treatment is not toward completion or self-realization but toward the subject's assumption of its constitutive lack.

Humanistic Self Actualization: Humanistic psychology (Rogers, Maslow) posits an intrinsic human drive toward self-actualization — the realization of one's authentic potential. The therapeutic relationship is warm, empathic, and non-directive, providing conditions under which the client's natural growth tendency can unfold. The self has a genuine, knowable core that can be accessed through honest reflection and genuine interpersonal contact; psychological health is the congruence between self-concept and experience.

Fault line: Lacan's schema implies the 'self' is an imaginary formation that obscures the symbolic determination of the subject; humanistic psychology treats the self as a given, authentic, and capable of actualization. For Lacan, what humanistic therapy calls 'growth' is likely consolidation of imaginary identifications — a deepening of alienation rather than its traversal.

[Psychoanalysis and its Teaching](#ch05.xhtml_tocbook-part-004) > The imaginary in neurosis and object relations

Theoretical move: The passage argues that neurotic impasses (hysterical and obsessional) are constituted entirely within the imaginary register—between little others and ego-images—and therefore cannot be resolved from within that register; the hysteric perpetuates an alienated desire mediated through the other's image while the obsessive deploys his ego as a puppet to stave off death, both strategies ultimately annulling desire and blocking genuine subjective engagement.

Lacan is talking here about the imaginary relationship, the projection of an image, which brings to mind for Fink (in Lacan 1966/2006a: 803) Lacan's L-schema, in which the move from ego to other recalls the move made by a knight.

[Psychoanalysis and its Teaching](#ch05.xhtml_tocbook-part-004) > Approaching neurosis in the imaginary vs. the symbolic

Theoretical move: Lacan argues that the IPA's ego-strengthening approach to neurosis deepens alienation by keeping the subject in the imaginary register, and that only orienting analysis through the symbolic Other—rather than the imaginary other of identification—can treat neurosis as a genuine question rather than a lure; this critique extends to all empiricist, biologistic, and behaviorist appropriations of psychoanalysis that destroy its symbolic foundation.

The Other in the L-schema is not approached by identification but by speech, and Lacan sees its use in psychoanalysis as the way to treating the 'sequence of neurosis' as a question (symbolic) and not a lure (imaginary).

Theoretical move: The passage argues that Lacan's 'return to Freud' culminates in a formal, symbolic account of the unconscious as the Other's discourse, articulated through the L-schema and R-schema, which positions subjectivity as constituted by signifiers at the level of the Other rather than by imaginary ego-dynamics—thereby decisively separating psychoanalysis from both Cartesian consciousness-philosophy and Jungian imaginary interpretation.

Theoretical move: The passage contextualizes Lacan's 'The Direction of the Treatment' as a theoretical turning point that pivots from an intersubjective/symbolic model of analysis toward a structural account of desire as the metonymy of lack-of-being, in direct opposition to ego psychology and object relations approaches that centre adaptation and the analyst's ego as goals of treatment.

Theoretical move: Lacan's critique of post-Freudian (especially ego-psychological) psychoanalysis is mobilized to argue that authentic analytic practice requires orienting from the symbolic axis (Other, lack, desire) rather than from imaginary ego-to-ego relations, with the L-schema formalizing why the analytic situation must be understood as four-positional rather than dyadic.

The L-schema formalizes Lacan's conceptualization of the analytic situation in which he distinguishes the symbolic relation between Subject and Other from the imaginary relationship between the ego and the other, the ego's specular image.

Theoretical move: Lacan's account of interpretation displaces ego-psychological and Gestaltian frameworks by grounding interpretation exclusively in the function of the signifier and the place of the Other, arguing that subjective transmutation occurs through the signifier rather than through ego-adaptive understanding, and that analytic direction must begin from subjective rectification rather than adaptation to reality.

[The Direction of the Treatment and the Principles of its Power](#ch05.xhtml_tocbook-part-008) > III. Where do we stand regarding transference?

Theoretical move: Lacan argues that the "central defect" of post-Freudian theories of transference (genetic/ego-psychological, object-relational, and intersubjective-introjective) is their reduction of the analytic situation to a dual, imaginary relationship, thereby neglecting the symbolic order and the constitutive impasse of desire; against these, Lacan insists that the direction of treatment must be oriented by the patient's signifiers rather than any normalizing ideal of adaptation or harmonious object-love.

As Lacan elaborates with the L-schema, one always encounters the imaginary axis, what he terms the wall of language. However, the analyst should not be tempted to situate himself in o (small other), at the level of his ego, but to intervene in the symbolic register.

Theoretical move: The passage argues that the direction of treatment must preserve a place for desire by refusing to respond at the level of demand; the phallus as signifier of lack structures the subject's desire metonymically, and analysis must lead the subject to confront the lack in the Other rather than offering new identifications that only deepen alienation.

Theoretical move: The L-schema is deployed to argue that the fundamental axis of analytic action is the Symbolic (between unconscious subjects), not the Imaginary (between egos), and that the analyst's strategic self-effacement/silence opens space for the unconscious to speak by dissolving the transference and instantiating the symbolic order as condition of possibility for the analysand's speech.

***L*** > **language**

Theoretical move: The passage traces four developmental phases of Lacan's theory of language, arguing that language (langage) functions as the single paradigm of all structure, that the unconscious is structured like a language of signifiers, and that language has both symbolic and imaginary dimensions—against any reduction of it to the symbolic order alone or to a mere code.

SCHEMA L represents these two dimensions of language by means of two axes which intersect. The axis A–S is language in its symbolic dimension, the discourse of the Other, the unconscious. The imaginary axis a'–a is language in its imaginary dimension.

***R*** > **repetition**

Theoretical move: The passage traces Lacan's successive redefinitions of Freudian repetition compulsion: from automatism tied to the complex, through the 1950s reformulation as the insistence of the signifier, to the 1960s recast as the return of jouissance — each move progressively de-biologising and re-semioticising (then re-libidinising) the concept while carefully distinguishing repetition from transference as its special clinical subset.

In SCHEMA L, repetition/insistence is represented by the axis A–S, while the axis a-a' represents the resistance (or 'inertia') which opposes repetition.

***O*** > ***objet (petit) a***

Theoretical move: This passage traces the full conceptual evolution of objet petit a across Lacan's work, showing how it migrates from a purely imaginary little other (schema L, 1955) through the object of desire/fantasy (1957) to the real cause of desire, surplus-jouissance, and finally semblance of being at the centre of the Borromean knot—demonstrating that the concept accumulates rather than replaces its earlier determinations.

In schema L, then, a and a′ designate indiscriminately the EGO and the COUNTERPART/SPECULAR IMAGE, and clearly belong to the imaginary order.
#14

An Introductory Dictionary of Lacanian Psychoanalysis · Dylan Evans

***I*** > **imaginary**

Theoretical move: The Imaginary order is defined not as mere illusion but as a structurally necessary, symbolically conditioned register whose basis is the mirror-stage ego-formation; the passage argues that reducing psychoanalysis to the imaginary (identification with the analyst, dual relationship) betrays the symbolic essence of analytic work, and that the only therapeutic purchase on the imaginary comes through its translation into the symbolic.

language is the 'wall of language' which inverts and distorts the discourse of the Other (see SCHEMA L)
#15

An Introductory Dictionary of Lacanian Psychoanalysis · Dylan Evans

***A*** > **algebra**

Theoretical move: Lacan's algebraic formalisation of psychoanalysis is theoretically motivated by three interlinked aims: scientific legitimacy, integral transmission of psychoanalytic knowledge, and the prevention of imaginary (intuitive) understanding in favour of symbolic manipulation — the mathemes and associated symbols thus function as epistemic and pedagogical devices, not mere notation.

Lacan begins to use algebraic symbols in his work in 1955 (see SCHEMA L), in an attempt to formalise psychoanalysis.

An Introductory Dictionary of Lacanian Psychoanalysis · Dylan Evans

***R*** > **resistance**

Theoretical move: Lacan reframes resistance as a structural feature of the analytic process rooted in the imaginary register of the ego, not the ill will of the analysand, and distinguishes it from defence by locating resistance on the side of the object (transitory, imaginary) and defence on the side of the subject (stable, symbolic), while also implicating the analyst's own resistance as the true source of any obstruction to treatment.

This is illustrated in SCHEMA L; resistance is the imaginary axis a–a' which impedes the insistant speech of the Other (which is the axis A–S).

***T*** > **topology**

Theoretical move: Topology is argued to be not merely a metaphor for structure but structure itself in Lacan's framework, privileging the function of the cut as a non-intuitive, purely intellectual means of expressing the symbolic order and distinguishing continuous from discontinuous transformations in psychoanalytic treatment.

***O*** > **other/Other**

Theoretical move: The passage establishes the fundamental Lacanian distinction between the little other (imaginary counterpart/ego-reflection) and the big Other (symbolic order, radical alterity, locus of speech), arguing that the big Other as symbolic order is primary over the big Other as subject, and that the unconscious is the discourse of the Other.

which is why the symbol a can represent the little other and the ego interchangeably in SCHEMA L
#19

An Introductory Dictionary of Lacanian Psychoanalysis · Dylan Evans

***Q***

Theoretical move: The passage argues that Lacanian theory, despite its predominance of triadic schemes, consistently requires fourfold (quaternary) structures to achieve adequate "subjective ordering" — and traces how the fourth element variously occupies the positions of death, the phallus, the letter, or the sinthome across different theoretical moments.

Other important quaternary structures which appear in Lacan's work are SCHEMA L (which has four nodes)
#20

An Introductory Dictionary of Lacanian Psychoanalysis · Dylan Evans

***I*** > **inversion**

Theoretical move: The passage traces Lacan's concept of 'inversion' from Freud's designation of homosexuality through to its properly Lacanian sense as a structural property of the specular image and imaginary phenomena, culminating in the claim that analytic communication is defined by the sender receiving his own message in inverted form — and that both senses are unified in Lacan's reading of Leonardo da Vinci via Schema L.

Thus in schema L, the imaginary is represented as a barrier blocking the discourse of the Other, causing this discourse to arrive at the subject in an inverted form.
#21

***C*** > **Counterpart**

Theoretical move: The counterpart (semblable) is theorized as the 'little other' of the Imaginary register—the other who is not radically Other but merely similar to the ego—thus grounding the formation of the ego in identificatory mirroring and distinguishing imaginary alterity from symbolic alterity.

***S*** > **Schema L**

Theoretical move: Schema L is Lacan's first and most sustained diagrammatic formalization of psychoanalytic structure, demonstrating that the symbolic relation between the Other and the subject is always partially blocked by the imaginary axis, while also representing the decentered subject stretched across four structural loci; it is positioned as the originary quaternary from which all subsequent schemata derive, and as the precursor to Lacan's mature topological work.

The main point of the schema is to demonstrate that the symbolic relation (between the Other and the subject) is always blocked to a certain extent by the imaginary axis (between the ego and the SPECULAR IMAGE).

xxn > The concept of analysis > **0. MANNONI: ft** *is the navel of speech.*

Theoretical move: Lacan argues that transference must be understood through the dialectic of the imaginary and symbolic registers rather than reduced to the real (Ezriel) or to ego-normalization (ego psychology); the imaginary relation, rooted in the mirror stage and the ideal ego, crystallizes transference while the symbolic—via speech and the analyst as mediating Other—enables the subject's integration of repressed history.

A schema of analysis... At 0, I place the unconscious notion of the ego of the subject... What is on the side of 0 passes over to the side of 0'. Everything which is proffered from A, from the side of the subject, makes itself heard in B, on the side of the analyst

Theoretical move: Lacan argues that topology is not an optional supplement to psychoanalytic formation but its very substance — the 'stuff into which the analyst cuts' — and uses the mathematician's disclosure that mathematical discourse conceals its own referent to illuminate the structural parallel with the psychoanalyst's position, where the unconscious (Urverdrangung) prevents any direct saying of what is spoken about; jouissance, caught in the net of language/the signifier, is identified as the hidden dimension that grounds desire and that only topology can begin to approach.

I - JACQUES LACAN"S OBJECT: A RAPID REMINDER

Theoretical move: The passage traces the theoretical development of the o-object (objet petit a) through Lacan's earliest graphs, arguing that (o) functions as the indispensable mediation between Subject and Other (via the Mirror Stage) and between Subject and Ego Ideal (via Schema R), while the Symbolic field alone provides the third term—the Name of the Father—that structures the whole process, inaccessible by any direct route.

One might point out here that in the field of the imaginary the two directions of the subject go either towards the object, or towards the ideal... One notes then that the Other which has come to the locus of the Name of the Father...

**Seminar 21: Wednesday 8 June 1966**

Theoretical move: Lacan argues that topology is not an optional supplement to psychoanalytic training but its very operative 'stuff' — the medium in which the analyst cuts the subject — and uses the mathematician's structural concealment of his object as a foil to show that the analyst's non-saying differs because an irreducible unconscious (Urverdrängung) prevents knowledge, while jouissance, caught in the net of language as sexual jouissance, is the hidden ground that desire defends against, pointing toward the death drive as the only genuine philosophical question.

if something remains to you from the schema SI, IO, you can see the fundamental arrangement which goes from S to the field of the big Other
#27

Seminar XIII · The Object of Psychoanalysis · Jacques Lacan · p.236

**Seminar 19: Wednesday 25 May 1966**

Theoretical move: Lacan uses Velázquez's *Las Meninas* as a visual matheme for the structural relationship between the gaze, the mirror, the Objet petit a, the Ideal Ego, and the field of the big Other: the painting is not a representation but a "trap for the look," and the royal couple's invisible gaze from the mirror-position enacts the function of the big Other in the narcissistic/specular relationship, while the o-object (objet petit a) remains irreducibly non-specular and therefore haunts the schema from outside it.

an articulation which makes it absolutely necessary to maintain in these functions their structure, with what this structure imposes from the register of the unconscious, that I imaged it through this image of the point S, with respect to a mirror
#28

Seminar XIII · The Object of Psychoanalysis · Jacques Lacan · p.253

**Seminar 21: Wednesday 8 June 1966**

Theoretical move: Lacan argues that topology is not an optional supplement for the psychoanalyst but the very material into which the psychoanalytic operation cuts, and that jouissance—placed on the hither side of the big Other and caught in the net of subjective topology as sexual jouissance—is the irreducible, unsayable dimension that language/desire both defends against and compels us to question, linking the emergence of the signifier to the individual's relation to jouissance via Freud's death drive.

Seminar XIII · The Object of Psychoanalysis · Jacques Lacan · p.28

I - JACQUES LACAN"S OBJECT: A RAPID REMINDER

Theoretical move: The passage traces the theoretical evolution of the o-object (objet petit a) through Lacan's earliest graphs—from the Mirror Stage to the L Schema and Schema R—arguing that (o) functions as the indispensable mediation between the subject and the Other, and between the subject and the ego ideal, while the symbolic field alone provides the third term (Name of the Father) that structures the whole process.

One might point out here that in the field of the imaginary the two directions of the subject go either towards the object, or towards the ideal... It can be seen how the quadrangle derives from the Z by joining the points which in the first graph are only reached by a round-about journey.

Seminar XIII · The Object of Psychoanalysis · Jacques Lacan · p.264

**Seminar 21: Wednesday 8 June 1966**

Theoretical move: Lacan argues that topology is not an optional supplement to psychoanalytic training but its very operative material, and uses the structural parallel between mathematical discourse (which speaks what it cannot name) and psychoanalytic discourse (which cannot name what it speaks about due to the irreducible unconscious) to re-ground the function of language, desire, and jouissance as the hidden field from which the subject withdraws its object.

Seminar XVIII · On a Discourse That Might Not Be a Semblance · Jacques Lacan · p.62

**Seminar 4: Wednesday 17 February 1971**

Theoretical move: Writing is theorized as the necessary condition for logic and for questioning the symbolic order, while the Phallus is recast not as a missing signifier but as an obstacle to the sexual relationship—what establishes jouissance as the condition of truth in analytic discourse.

the written taken up all by itself, whether it is a matter of one or other schema, the one that is called L or any other one whatsoever, or the big graph itself, presents an opportunity for all sorts of misunderstandings
#32

Seminar II · The Ego in Freud's Theory and in the Technique of Psychoanalysis · Jacques Lacan · p.332

XXIII > A, m, a, S > FATHER BEIRNAERT: Why?

Theoretical move: Lacan argues that the death drive is not a biological tendency but the mask of the Symbolic order insofar as the Symbolic has not yet been realised — the Symbolic is simultaneously non-being and insisting to be, and analysis reveals not the subject's biological reality but the signification of his lot within a received symbolic speech.

What insists, what simply demands to pass through, takes place between A and S. Whereas transference takes place between m and a.
#33

Seminar II · The Ego in Freud's Theory and in the Technique of Psychoanalysis · Jacques Lacan · p.328

XXIII > A, m, a, S > FATHER BEIRNAERT: Why?

Theoretical move: Lacan maps Freud's three-stage account of the cure (signification → imaginary reminiscence → repetition) onto the four-pole schema A.m.a.S, arguing that the ego's imaginary resistance interrupts the fundamental symbolic discourse running between the radical Other (A) and the subject (S), and that analytic transference works precisely by substituting the radical Other for the imaginary little other.

I will turn once again to the four poles which I have more than once written on the board... A, which is the radical Other... m, the ego, and a, the other... S, which is simultaneously the subject, the symbol, and also the Es.
#34

Seminar II · The Ego in Freud's Theory and in the Technique of Psychoanalysis · Jacques Lacan · p.257

XVIII > Introduction of the big Other > Objectified analysis

Theoretical move: Lacan critiques Fairbairn's object-relations reformulation of analysis as exemplary of a deeper theoretical error: the confusion of the real, imaginary, and symbolic registers under the single undifferentiated term 'object', which transforms analysis into an ego-remodelling exercise grounded in the specular/imaginary relation rather than the symbolic register of speech.

The schema I gave you last time assumes that speech is propagated like light, in a straight line. That shows you the extent to which it is only metaphorical, analogical.
#35

Seminar III · The Psychoses · Jacques Lacan · p.27

**I** > **1**

Theoretical move: The passage argues that the distinction between neurotic repression and psychotic repression is a matter of their different positions within the symbolic order, and that misrecognizing the autonomy of the symbolic—substituting imaginary recognition for symbolic exchange—is the structural cause of analytic-triggered psychosis; verbal hallucination is theorized as the moment the subject collapses into identification with the ego, speaking to itself in the real.

Our schema, I remind you, represents the interruption of full speech between the subject and the Other and its detour through the two egos, о and o,' and their imaginary relations.

Seminar III · The Psychoses · Jacques Lacan · p.174

**XII** > **The hysteric's question**

Theoretical move: By analyzing Schreber's delusion through the schema of analytic communication, Lacan argues that in psychosis the big Other—where being is realized through speech—is foreclosed, reducing discourse to an internal echo (automatism) that cannot resolve the subject's constitution; this structural difference from neurosis must be clarified before any technique for working with psychotics can be formulated.

Between S and O, the fundamental speech that analysis must uncover, we have the interference of the imaginary circuit, which resists its passage. The imaginary poles of the subject, о and o', coincide with the said specular relation, that of the mirror stage.
#39

Seminar III · The Psychoses · Jacques Lacan · p.88

**VI**

Theoretical move: Lacan distinguishes the psychotic's relation to reality from that of the normal subject by showing that what is at stake in psychosis is not belief in the reality of hallucinations but an unshakeable *certainty* that phenomena concern the subject — a certainty that is structurally prior to and independent of reality-testing, and which must be understood through the symbolic frame (L Schema) rather than reduced to normal mechanisms like projection.

This is the requirement that my little square meets, which goes from the subject to the other and, in a way, here, from the symbolic towards the real, subject, ego, body, and in the contrary sense towards the big Other of intersubjectivity

Seminar IV · The Object Relation · Jacques Lacan · p.9

Jacques Lacan The Object Relation > THEORISING THE LACK OF OBJECT > INTRODUCTION

Theoretical move: Lacan inaugurates Seminar IV by arguing that the Object Relations school's reduction of analytic experience to a dual subject-object relation (line a-a') is theoretically inadequate: against this, he retrieves Freud's own notion of the object as a *lost* and re-found object, constitutively marked by repetition and irreducible tension, which requires the full complexity of the L-Schema (subject/Other/imaginary axis) rather than a simple dyadic rectification.

This diagram lays out, first and foremost, the subject's relation to the Other. In the way that it is naturally constituted at the start of analysis, this relation is one of virtual speech wherein the subject receives, from the Other, his own message in the form of unconscious speech.
#42

Seminar IV · The Object Relation · Jacques Lacan · p.115

Jacques Lacan The Object Relation > THE PERVERSE WAYS OF DESIRE > A CHILD IS BEING BEATEN AND THE YOUNG HOMOSEXUAL WOMAN

Theoretical move: Lacan analyses the three stages of the beating fantasy to argue that perverse fantasy represents a radical desubjectivation in which signifiers are preserved in "pure state" - stripped of intersubjective signification - and that this structure (like the fetish as screen-memory) reveals the valorisation of the imaginary image as a frozen residue of unconscious speech articulated at the level of the big Other; perversion is therefore not a pre-Oedipal relic but is fully constituted through and by the Oedipus complex.

In referring to our diagram, the imaginary relationship... is inscribed between the two vertices a-a' in a relation that is marked to a greater or lesser degree by specularity and reciprocity between the ego and the other party. But here we find ourselves in the presence of something that takes place on the line S-A, namely unconscious speech.

Jacques Lacan The Object Relation > THE SIGNIFIER AND THE HOLY SPIRIT > ON ANALYSIS AS BUNDLING AND THE CONSEQUENCES THEREOF

Theoretical move: Lacan critiques the object-relations school (Marty, Fain, Bouvet) for reducing the analytic situation to a real dyadic relationship aimed at collapsing imaginary distance, thereby foreclosing the symbolic dimension of speech and the Other — and shows that this technical orientation produces paradoxical perverse reactions, particularly in obsessional cases. Against this, he reaffirms that the symbolic (S-A) and imaginary (a-a') axes must be held in their mutual, crossing functioning, with the paternal function and Oedipus complex as the fourth term that re-situates the preoedipal imaginary triad.

Seminar IV · The Object Relation · Jacques Lacan · p.125

Jacques Lacan The Object Relation > THE PERVERSE WAYS OF DESIRE > A CHILD IS BEING BEATEN AND THE YOUNG HOMOSEXUAL WOMAN

Theoretical move: Lacan uses the case of the young homosexual woman to demonstrate how perversion arises from a structural permutation within the Imaginary-Symbolic-Real triad: when the symbolic father intrudes into the imaginary plane as a real event (giving a child to the mother), the subject identifies with the paternal function and reorganises her desire around what the love-object lacks (the symbolic phallus), revealing that love is essentially a gift of what one does not have.

This can be translated onto our diagram. The father, who at the previous stage was at the level of the big Other, has now passed to the level of the ego, to the extent that the girl has taken the male position. At a', there is the lady.
#47

Seminar IV · The Object Relation · Jacques Lacan · p.425

FAREWELL > FROM HANS-THE-FETISH TO LEONARDO-IN-THE-MIRROR

Theoretical move: Lacan argues that sublimation is structurally correlated with an inversion of the ego/other relation in the imaginary register, such that the very process of de-subjectification (sublimation) entails a fundamental self-forgetting—illustrated through Leonardo's mirror writing as the symptom of a radical alienation in which the subject addresses himself from the position of his own imaginary other.

This is inscribed, along with the necessity of the big Other, here on the diagram to which I have been urging you to refer as a means of charting these problems. [diagram caption: Leonardo's inversion]
#48

Seminar IV · The Object Relation · Jacques Lacan · p.118

Jacques Lacan The Object Relation > THE PERVERSE WAYS OF DESIRE > A CHILD IS BEING BEATEN AND THE YOUNG HOMOSEXUAL WOMAN

Theoretical move: Lacan reconstructs Freud's case of the young homosexual woman through the L Schema's symbolic (S-A) and imaginary (a-a') axes, arguing that the phallus functions as the imaginary element through which the subject enters the symbolic dialectic of the gift, and distinguishing between frustration of love (intersubjective, symbolic) and frustration of jouissance (real, non-generative of object-constitution) against Klein and Winnicott's formulations.

On the axis that runs S-A, insomuch as it is here that symbolic signification must come about and be established, lies the entire genesis of the subject in the present. On the other hand, the imaginary interposition a-a' is where the subject finds her status, her object structure

Seminar V · Formations of the Unconscious · Jacques Lacan · p.150

**FORECLOSURE OF THE NAME-OF -THE-FATHER** > 157 And we also have this schema:

Theoretical move: The passage argues that the subject (S) is a structurally "dummy" fourth term outside the Oedipal triangle, dependent on the signifiers at the locus of the Other, and that the imaginary triangle—anchored by the ego/specular image, the mother-father-child triad, and the phallus as third point—maps how the paternal metaphor transforms the first (symbolic) triad into a second (imaginary) one; the phallus is thus the central object with which the subject imaginarily identifies, irreducible to a mere part-object.

I represent here by this zigzag, and which elsewhere, in my article,'The Purloined Letter', I called schema L.
#51

Seminar V · Formations of the Unconscious · Jacques Lacan · p.492

**EXPLANATION OF THESCHEMAS** > 3 **Concerning the Oedipus complex**

Theoretical move: The passage argues that the Oedipus complex is a structural prerequisite for theorizing pre-Oedipal configurations (perversion, neurosis, homosexuality), and uses the superimposition of two schemas—one imaginary, one intersubjective—to give 'identification' a precise topological meaning: the mutual substitution of subjects in speech.

the relationship to the mother in masculine homosexuality is structured in a current drama that is being played out between S, a, a', A.
#52

Seminar V · Formations of the Unconscious · Jacques Lacan · p.489

**EXPLANATION OF THESCHEMAS** > **1 The signifying chain**

Theoretical move: The passage argues that the signifying chain is the irreducible structural condition of human subjectivity, the unconscious, and intersubjectivity alike — and that failing to grasp this leads to technical deviations (e.g. Bouvet's imaginary-centric technique), which Schema L is designed to correct by showing how the vector from the Other to the subject must traverse, not reduce to, the imaginary relation.

Schema L [see Ecrits, p. 53] is intended precisely to indicate that the question is whether, along the vector that goes from the Other to the subject, there is anything that traverses this imaginary relationship or not.
#53

Seminar V · Formations of the Unconscious · Jacques Lacan · p.216

FROM IMAGE TO **SIGNIFIER - IN PLEASURE AND IN REALITY**

Theoretical move: The passage argues that the illusory object cannot be adequately theorized through the imaginary alone but only through its function as a signifying element within a signifying chain — the mirror stage installs a double movement (imaginary identification with the body-image vs. symbolic identification along the ego-ideal axis) whose structural schema is necessary to distinguish identification from idealization, illusion from image, and to account for perversion, fetishism, and psychosis without reducing them to instinctual or genetic regression.

The field of experience of reality is represented here by the triangle, M-i-m, which sits on the axis of the previously defined abscissa, whereas the more enigmatic, homologous and inverse triangle, M-m-E, creates the subject's field
#54

Seminar VI · Desire and Its Interpretation · Jacques Lacan · p.229

THE LAUGHTER OF THE IMMORTAL GODS

Theoretical move: Lacan formalizes the quadripartite structure of subject-formation by showing that the specular couple [a-a'] is always already regulated by the more primitive dyad of the unconstituted subject and the mother-as-One, and that the birth of metaphor (substitution) is the moment at which the object is symbolized and desire properly emerges — yielding the formula of fantasy ($◇a) inscribed within a four-term schema.

Do not forget that all psychoanalytic authors situate the locus of psychotic or parapsychotic anomalies... in the central relationship between mother and child... these relations are established... as a quadripartite relationship
#55

Seminar VI · Desire and Its Interpretation · Jacques Lacan · p.217

SACRIFICING THE TABOO QUEEN

Theoretical move: Lacan uses the chess metaphor — specifically the patient's refusal to sacrifice his queen — to argue that the phallus is a hidden signifier displaced onto the female partner (wife/analyst), and that the subject's desire is structured around preserving this phallic substitute at the cost of remaining bound in a fantasy of omnipotence; the analytic task is to bring this secret relation between subject and partner into the open.

Consider, if you will, the quadrangular schema on which we find the subject, the other, the ego qua other's image, and the Other with a capital O [the L schema]. Here the question is where the signifier as such appears.
#56

Seminar VI · Desire and Its Interpretation · Jacques Lacan · p.129

DESIRE'S PHALLIC MEDIATION

Theoretical move: Desire cannot be reduced to demand or frustration but must be grasped through the tight knot of Real, Imaginary, and Symbolic; the dream of the dead father exemplifies how the imaginary interposition of the father's image props up desire as a shield against the anxiety of subjective elision, with the fantasy formula (S◇a) expressing the structural absence of the subject that is constitutive of desire itself.

In this simplest form possible, the formula (S◇a) expresses the same relationship as the one that interposes itself in the partially unconscious discourse coming from the Other with a capital O [grand Autre] and going toward the subject, in the quadrilateral schema that you already know, the one known as the L schema.

Chapter 5 Figurations of the *Objet a* > Why One and One Make Four

Theoretical move: By mapping gestalt concepts (figure/ground) onto the Schema R and contrasting it with Schema L, Boothby argues that symbolic castration is the process of "demotivation" that opens the real between the imaginary axis (m-i) and the symbolically mediated axis (I-M), distinguishing the fuller picture of the Oedipus complex from the neurotic, analytic situation mapped by Schema L.

If the movement of demotivation fails, the symbolic axis of the ego ideal fails to be differentiated from the imaginary... the Schema L is rightly interpreted as the schema of the analytic situation.
#60

Freud as Philosopher: Metapsychology After Lacan · Richard Boothby

Chapter 2 Between the Image and the Word > From Image to Sign

Theoretical move: The passage argues that the signifier operates at the unstable juncture between the Imaginary and the Symbolic: its gestalt must appear perceptually yet immediately self-evacuate, and repression itself can be theorized as a transposition from symbolic to imaginary register—the signifier's body becoming an opaque image rather than a transparent vehicle of meaning.

To locate what Lacan calls the 'signifier' in the Schema L, we might well place it in the exact center, at the 'X' of the crisscrossing imaginary and symbolic axes.

Chapter 5 Figurations of the *Objet a* > Why One and One Make Four

Theoretical move: By mapping the *objet a* across Schema L, Schema R, the Gestalt figure/ground distinction, and the Greimasian semiotic square, Boothby argues that the *objet a* is not a positional object but an "objectality" function that emerges from the structural tension between das Ding (maternal) and the paternal Law (symbolic order), a tension whose topology is best captured by Schema R rather than Schema L.

Lacan also employed a number of graphs and schemata, such as the Schema L, to which we have already referred more than once, and his later Schema R.
#63

Freud as Philosopher: Metapsychology After Lacan · Richard Boothby · p.82

Chapter 2 Between the Image and the Word > The Unconscious Play of the Signifier

Theoretical move: By mapping Freud's thing-presentation/word-presentation distinction onto Lacan's Imaginary/Symbolic axes via the Schema L, Boothby argues that repression is not a topographic displacement but a dynamic shift of valence between two psychical functions—a structural transformation in which a signifying process becomes captured in an imaginary formation, rendering the unconscious a process rather than a receptacle.

Precisely such a view is suggested by the most fundamental schema of Lacan's work: the Schema L... Between the ego and its objects stretches the axis of imaginary relations. Between the Other of the symbolic order and the Subject determined by it lies the symbolic axis.
#64

The Lacanian Subject: Between Language and Jouissance · Bruce Fink · p.190

Psychoanalysis and Science > Parenthetical Structures

Theoretical move: By mapping the asymmetry of the L Chain onto the subject/Other split and identifying the parenthesis as the operator that introduces heterogeneity into the unary-trait repetition, Fink argues that the letter imposes a "parenthetical structure" on the subject — structurally enacting alienation and separation — and that object (a) is what gets bracketed in this process.

The status of a and a' was not yet fully accounted for at the Schema L stage in his development, but he claims that his later topology does account for them.
#65

The Lacanian Subject: Between Language and Jouissance · Bruce Fink · p.185

Psychoanalysis and Science > Stalking the Cause

Theoretical move: By retranscribing Schema L as Chain L using a parenthetical/binary formalism, Fink shows how object a emerges as a structural remainder—the *caput mortuum* of the signifying chain—thereby demonstiting that object a's causal function with respect to desire is inscribed in the very topology of the symbolic chain rather than being a supplementary concept added from outside.

His intent seems to be to give a retranscription of his well-known Schema L, while at the same time updating it in such a way as to bring out the role of object a, a concept he spent a good deal of time elaborating between 1956 and 1966.
#66

The Parallax View · Slavoj Žižek · p.115

The Birth of (Hegelian) Concrete Universality out of the Spirit of (Kantian) Antinomies > Odradek as a Political Category

Theoretical move: The passage argues that both Levinas and Adorno fail to account for the truly "inhuman" dimension of subjectivity—exemplified by the Muselmann—which cannot be subsumed under any ethical or normative frame; Žižek uses Agamben's Muselmann, the L Schema, and Kafka's Odradek to articulate a "neighbor" as monstrous, impenetrable Thing that exceeds Levinasian face-ethics and demands a radically different conceptualization of the human/inhuman boundary.

Is this structure not that of the so-called 'Schema L' of communication from early-1950s Lacan, in which the 'true communication' (the diagonal S–A) is cut across by the diagonal a–a′ of the imaginary relationship?
