Cause and the Law

In Copjec's reading of Lacan (drawn from Read My Desire), "Cause and the Law" names the critical distinction Lacan draws between his own concept of cause and every model that reduces cause to lawfulness — whether the Newtonian covering-law model (cause as a determinate, sufficient antecedent condition) or Hart & Honoré's norm/deviation model (cause as departure from an expected regularity). For Lacan, cause is not a positive, present, or recoverable condition; rather, it operates precisely at the site of a gap, a failure, an absence. Cause is what cannot be fully subsumed under law because it belongs structurally to the register of the Real — that which resists symbolization — rather than to the Symbolic order of regularities and norms. To say that cause is tied to the law is to pretend that effects can be fully accounted for by their antecedents; Lacan's move is to insist that something always escapes such accounting, and that remainder — irreducible, non-symbolizable — is the true locus of causality.

Copjec extends this by grounding the concept not in psychology but in the materiality of language and in the body as an incomplete symbolic construct. The unconscious, on this account, is never present in the field of consciousness it effects: it functions as a cause that cannot appear as such within the phenomenal domain it organizes. This aligns with the Lacanian principle that the subject is constituted by a lack — a manque-à-être — and that the Real interrupts, rather than confirms, symbolic lawfulness. Cause, for Lacan, thus belongs to the same structural family as the objet petit a and the symptom: entities that mark the point at which the symbolic order fails to close upon itself.

This concept appears once, in radical-thinkers-joan-copjec-read-my-desire-lacan-against-the-historicists-verso, where Copjec mobilizes it as a polemical and theoretical wedge. Her argument is directed against historicist frameworks that assimilate Lacanian cause to social or discursive norms — i.e., to law in the covering or normative sense. By distinguishing Lacan's cause from law, Copjec defends the irreducibility of the Real (one of the cross-ref'd canonicals) against any reduction to the Symbolic. The concept thus functions as a specification and a defense: it specifies what is genuinely Lacanian about causation by contrasting it with competing models, and it defends psychoanalytic theory against its historicist critics.

The concept's relationship to the cross-ref'd canonicals is dense. It presupposes Lack: cause-as-absence is only legible once we accept that the symbolic order is constitutively incomplete and that lack is a structural, not contingent, feature of reality. It presupposes Language and the Symbolic: the body as an incomplete symbolic construct means that what escapes linguistic capture — the Real — is what functions as cause. It is directly opposed to the Principle of Sufficient Reason (every effect has a sufficient, recoverable cause), which is exactly the Newtonian covering-law model Copjec critiques. And it recasts the Subject as constituted by something that can never appear in Consciousness — the unconscious cause is never present to the field of awareness it organizes, reinforcing the corpus-wide decentring of consciousness traced across Lacan's Seminars and Freudian metapsychology. In this sense, "Cause and the Law" is a crossroads concept: it crystallizes the intersection of Real, Lack, Language, and the decentred Subject into a single epistemological claim about the limits of causal explanation.

Lacan refers in The Four Fundamental Concepts of Psychoanalysis when he says that his concept of cause is to be distinguished from that which sees it as law.

The phrase "distinguished from that which sees it as law" carries the full theoretical weight: it names the two competing ontologies in a single gesture — cause-as-law (determinate, nomological, sufficient) versus cause-as-gap (indeterminate, Real, never fully present) — and anchors the distinction in Lacan's own declared theoretical program in The Four Fundamental Concepts, the seminar where the unconscious, repetition, transference, and the drive are elaborated precisely as entities that resist lawful closure.
