Impossibility-to-Prohibition

Impossibility-to-Prohibition names the structural transition whereby the originary, constitutive impossibility of the subject — the fact that no object can restore the lost jouissance that founds subjectivity — is converted, through repetition, into a social-juridical prohibition. In the first moment, impossibility is ontological: the subject is constituted through a foundational loss (the entry into language, the separation from das Ding) that cannot be undone. No object, no act of satisfaction, could simply fill this void, because the void is what makes the subject possible. In the second moment, when this originary sacrifice is repeated at the level of the social bond — when subjects collectively renounce enjoyment to enter sociality — impossibility is recast as prohibition. The social fiction installs the idea that enjoyment would be available were it not for the law's interdiction. This is the constitutive lie at the heart of socialization: prohibition implies that something is being withheld, that full enjoyment is possible but forbidden, when in fact the impossibility precedes and exceeds any prohibition.

This conversion has direct consequences for the persistence of sacrifice as a social practice. If prohibition merely re-stages impossibility, then sacrifice — in religion, war, or ritual — is never truly "for" an external end. It is, rather, a way of enjoying the loss itself, repeating the death drive's insistence at the collective level. The social bond is thus grounded not in a shared positive content (a common good) but in a shared relation to loss, and ideology sustains this bond by maintaining the fiction of prohibition where there is only impossibility — by making subjects believe that the Other withholds enjoyment rather than that enjoyment was always-already foreclosed.

This concept appears in enjoying-what-we-don-t-have-th-todd-mcgowan (p. 160) and is central to McGowan's argument about enjoyment, sacrifice, and the social bond. It operates as a specification and application of several canonical concepts held in tension. With respect to the Lost Object and Desire, impossibility-to-prohibition names the precise mechanism by which the ontological gap — the fact that the lost object is irrecoverable, structurally absent rather than empirically withheld — becomes misread as a juridical interdiction. Desire is co-constituted with prohibition (as the canonical definition notes: "it is from the very gap of the inscribed prohibition that there derives the conjunction of this desire and of this law"), and impossibility-to-prohibition explains how that co-constitution is socially produced and perpetuated as a lie. The concept is equally an extension of the Death Drive: the social repetition of sacrifice is the death drive operating at the collective level, reproducing the originary loss not in order to overcome it but to enjoy it — the drive's indifference to outcome, its insistence on repetition beyond any pleasure-principle calculation, becomes the engine of social cohesion.

With respect to Ideology and Fetishistic Disavowal, impossibility-to-prohibition identifies the specific ideological operation that sustains the social bond: the substitution of a juridical fiction (prohibition) for an ontological truth (impossibility). This is structurally homologous to the "I know very well, but nevertheless" of fetishistic disavowal — subjects may sense that enjoyment is impossible, yet social practice proceeds as if it is the law that withholds it, thereby sustaining the fantasy that full enjoyment is achievable and that sacrifice will one day be redeemed. The concept also resonates with Jouissance and Demand: prohibition installs the Other as the agent who withholds jouissance, converting the subject's impossible demand for the absolute satisfaction of the Other into the specific grievance that ideology can exploit and organize around sacrifice.

Th e transition from the initial sacrifi ce that constitutes subjectivity to its repetition that constitutes the social bond is the transition from impossibility to prohibition.

The quote is theoretically loaded because it maps two distinct structural registers — "constitutes subjectivity" (the ontological, singular, originary loss) and "constitutes the social bond" (the collective, repeated, ideological) — onto a single directional movement, "the transition from impossibility to prohibition," thereby identifying the exact hinge at which psychoanalytic ontology becomes social ideology: the subject's constitutive void is re-narrated as a withheld object, and death-drive repetition becomes social sacrifice.
