Immanence

In Copjec's argument in Read My Desire, "immanence" names the philosophical-political presupposition she attributes to Foucault's analytics of power: the idea that the social field is fully constituted by the relations of power and knowledge that operate within it, such that no element of that field can exceed or stand outside those relations. A cause is "immanent within the field of its effects" when it has no independent existence beyond what it produces — there is no remainder, no gap, no surplus that escapes predication by the immanent network. Copjec identifies this as the structural core of historicism: if society is entirely self-enclosed in its power-knowledge relations, then any given subject, practice, or phenomenon is exhaustively explicable by its position within that web. Nothing is left over.

The problem Copjec diagnoses is that Foucault's own best insights — his gestures toward a "surplus existence" that resists classification, toward forms of being that escape the archive — are sabotaged by this immanentist premise. The Lacanian counter-position she defends is that the symbolic order is constitutively non-all: there is always a real that does not bend to predication, a lack or excess — figured in the "il y a de l'Un" or in the non-existence of "The" Woman — that the symbolic cannot absorb. Immanence, in Copjec's critical usage, is thus the philosophical name for the foreclosure of this gap, the denial of the Real's resistance to the Symbolic, and therefore the denial of the subject as such.

The concept lives in the opening polemical argument of october-books-joan-copjec-read-my-desire-lacan-against-the-historicists-october, where it anchors Copjec's diagnosis of Foucault's historicism as a philosophical error with structural consequences. It functions as a critical foil rather than a positive theoretical resource: immanence is precisely what Lacanian theory refuses. The concept directly cross-references Historicism (the label Copjec applies to any position that reduces social reality to its immanent relations) and Ideology (whose Lacanian critique similarly insists that social reality is never self-sufficient but is constitutively incomplete, requiring fantasy to paper over its antagonism). Against ideology as a closed symbolic totality, Lacan insists on the Real as that which cannot be symbolized — the exact anti-immanentist move Copjec defends.

The concept also bears a close relation to Feminine Sexuality and the Not-all: the reason immanence fails is precisely because the symbolic order is structured as "not-all," with no universal exception that could close it. The non-existence of "The" Woman is, for Copjec, a concrete instance of the anti-immanentist claim — there is no signifier adequate to totalize the feminine, no immanent cause sufficient to its effects. Similarly, Judgment in its Lacanian register (the primordial Bejahung that inaugurates signification, and its failure in Verwerfung/Foreclosure) points to a founding moment that is irreducibly prior to any field of effects — precisely not immanent within it. Immanence is thus the concept Copjec uses to name the enemy of all these positions simultaneously.

Read My Desire: Lacan Against the HistoricistsJoan Copjec · 1994 (p.16)

it is this notion of immanence, this conception of a cause that is immanent within the field of its effects, with which this book quarrels and repeatedly condemns as historicist.

The phrase "a cause that is immanent within the field of its effects" is theoretically loaded because it identifies the precise philosophical structure — a self-enclosed causal loop — that Copjec equates with historicism; by naming "immanence" as the target of the entire book's quarrel, she announces that the Lacanian wager is irreducibly about the non-closure of cause and effect, i.e., about a Real that always exceeds the symbolic field it traverses.
