Père-version

Père-version is Lacan's punning reformulation of the paternal function, produced by splitting the word "perversion" into its French components: père (father) + version (turning/orientation). The move is not merely wordplay but a precise theoretical operation: it redefines what it means to exercise the paternal function not as adherence to a moral or social norm, but as a structural orientation toward a woman as object a — the small other that causes desire. A father earns legitimate authority (love, respect) only insofar as his desire is structured through a woman who functions for him as the object-cause of desire; that is, only insofar as he himself is a desiring subject properly knotted to the phallic order. The père-version thus collapses the apparent opposition between perversion and the paternal by revealing that the father's function is itself constitutively "per-verse" — it is always already a turning-toward (versement) that is, structurally speaking, père-verted.

In the later development (Seminar XXIII), père-version is extended topologically: it designates the very structure of the Borromean knot itself (noeud bo), implying that the knotting of the three registers — Real, Symbolic, Imaginary — is co-extensive with the paternal function understood as père-version. This means the paternal function is not a merely symbolic operation (as in the classical Name-of-the-Father formulation) but a topological one: it is the knot, the point where the registers are held together, and where "all human sexuality" is revealed as perverse in Freud's sense — structured by the partial object, never achieving the mythical genital totality.

Père-version appears across two late seminars — jacques-lacan-seminar-22 and jacques-lacan-seminar-23-cormac-gallagher — placing it squarely in Lacan's final topological period, where the classical symbolic account of the paternal function is being reworked in terms of the Borromean knot and the sinthome. In relation to the canonical Paternal Function, père-version functions as a specification and radicalization: where the classical account identifies the paternal function with the Name-of-the-Father as a symbolic substitution (the paternal metaphor), père-version relocates the function in the father's own libidinal economy — specifically, in whether he takes a woman as his object a. The father is not adequate to his function by virtue of being symbolic law; he must himself be a desiring subject in the precise Lacanian sense, structured by castration and the phallic order.

In relation to the Borromean Knot and the Sinthome (the cross-referenced canonicals from jacques-lacan-seminar-23-cormac-gallagher), père-version marks the point where the paternal function and the topological knotting of RSI converge: the père-version is the noeud bo, i.e., the knot itself is the operation by which the three registers are oriented and held. This aligns with the logic of the fourth ring (sinthome as supplementary knotting agent) — père-version names the structural condition under which this knotting succeeds. The concept also implicitly engages Castration and the Signifier: the father's desire, oriented per-versely toward woman-as-object-a, presupposes his own subjection to the phallic function (castration), while the Unconscious, as a form of writing, underpins the reformulation of the symptom and père-version as modes of inscription in the Real.

Seminar XXII · R.S.I.Jacques Lacan · 1974 (p.61)

A father has only a right to respect, indeed to love, if the aforesaid, the aforesaid love, the aforesaid respect, is, you are not going to believe your ears, per-versely (père-versement) orientated, namely, made by a woman (fait d'une femme), the small o-object which causes her desire.

The quote is theoretically loaded because it ties the legitimacy of the paternal function (right to respect, to love) not to symbolic authority or law but to a libidinal condition: being père-versement orientated toward a woman as the small o-object which causes her desire — that is, toward woman as object a. The phrase "you are not going to believe your ears" signals the deliberate provocation: Lacan is inverting the moral register of "perversion" and relocating it as the structural condition of fatherhood itself.
