Being - Having Alternation

Being–Having Alternation names the structural oscillation that Lacan extracts from Freud's second form of identification—the one that proceeds not by total incorporation but by the subject's differential relation to a single trait or object. In this mode, the subject does not become the object (incorporation) nor does it simply desire what the object desires (hysteric identification); instead, it moves between two poles: being the phallus/object for the Other versus having it as a possession held within the symbolic order. The oscillation is not a temporal sequence but a logical one: neither pole can be held simultaneously, because the subject's position in the symbolic is constitutively split. To be the object of the Other's desire is to have vanished as a subject; to have the object is to be marked by its absence as something one lacks. The alternation is therefore indexed to the zero-and-one logic Lacan introduces in Seminar XII—the subject flickers between presence and absence, fullness and void, in a rhythm structurally homologous to the binary of the signifier.

Lacan situates this alternation within the tripartite framework of privation, frustration, and castration. It corresponds most closely to the castration register, where the object at stake is the imaginary phallus and where the agent of the operation is the symbolic law. Because the phallus cannot be both had and been at once—having it requires giving up the position of being it—the alternation exposes the irreducible incompleteness of any imaginary relationship to the object of desire. Post-Freudian analytic practice, in Lacan's critique, collapses this structural difference, treating the relation to the object as a matter of ego-strength or object-relations rather than as a structural consequence of the subject's entry into language.

This concept appears in jacques-lacan-seminar-12-1 (p. 134) as part of Lacan's critical rereading of Freud's three forms of identification. It sits at the intersection of several canonical concepts. In relation to Castration, the Being–Having Alternation is its imaginary correlate: castration is the symbolic operation that makes the phallus unavailable for simultaneous being and having, and it is precisely this structural impossibility that the alternation dramatizes. In relation to Identification, the concept specifies Freud's second identificatory mode—partial, trait-based identification—by showing its logical structure as an oscillation rather than a stable position. In relation to Demand and Desire, the alternation helps explain why demand can never be fully satisfied: the subject's position relative to the object perpetually shifts, so that whatever is demanded is either already what one is (and therefore cannot be given) or what one lacks (and therefore cannot fill the gap desire requires). In relation to the Ego Ideal, the alternation resonates with the subject's movement between imaginary projection (ideal ego, being the image) and symbolic introjection (ego ideal, having a point in the Other from which one is seen)—two poles that cannot coincide.

The concept is an extension and internal specification of the castration/identification nexus rather than a critique or departure from it. Its singularity lies in foregrounding the dynamic, oscillating quality of the subject's relation to its object—something that static structural descriptions of castration or identification tend to suppress. Lacan's note that the alternation "is only a mystery" for Freud signals his own theoretical ambition: to provide the tripartite (privation/frustration/castration) framework that will dissolve that mystery by locating the alternation within the logic of the subject's constitutive split between zero and one.

the alternation between being and having… That from not having the object of choice the subject comes then… but he also tells us that this is only a mystery for him

The phrase "alternation between being and having" condenses the logical structure in a single chiasm: "being" and "having" are not synonyms but mutually exclusive positions relative to the object, and calling their movement an alternation (rather than, say, a conflict or a choice) insists that neither pole is ever definitively settled. The clause "this is only a mystery for him"—attributed to Freud—performs Lacan's critical gesture: it marks the point where Freud's descriptive account stops and where a structural explanation (privation/frustration/castration) must begin.
