Ethical Transubstantiation

Ethical Transubstantiation is the conceptual operation Župančič identifies as the hidden and unresolved problem at the heart of Kantian ethics: not the purification of the will from pathological inclination, but the passage by which pure practical form must itself become a materially efficacious drive. For Kant, the moral law commands from the side of pure reason—it is formal, empty of any particular content or sensuous motive—yet it must somehow produce a real effect in the phenomenal world, must actually move the subject to act. The gap between form and material efficacy is not solved but concealed by Kant, and Župančič names this concealed passage 'ethical transubstantiation': the quasi-miraculous conversion of a mere form into something with the force and materiality of a drive. The analogy with the theological term is precise—just as transubstantiation names the conversion of substance while form appears unchanged, here the reverse movement is required: form must acquire the substance of causal-motivational force without ceasing to be purely formal.

Župančič's argument is that this conceptual necessity is not an embarrassment that further Kantian refinement could dissolve; it is, rather, the precise point where Kant's ethics touches the Lacanian problematic. The Kantian 'pure form' must become drive in the same structural way that, in Lacan's topology, the passage from demand to desire is mediated by the objet petit a—a remainder or surplus that is neither the content of any particular demand nor reducible to formal structure alone, but is their real leftover. Ethical transubstantiation is therefore the name for the structural homology between Kant's aporia (pure law → material drive) and Lacan's formula (demand → objet petit a → desire), a homology that reveals the Real as the hinge of any genuinely non-pathological ethics.

The concept appears exclusively in alenka-zupancic-ethics-of-the-real-kant-and-lacan-2000 (p. 28), situated at the opening of Župančič's comparative argument between Kantian and Lacanian ethics. It functions as a diagnostic term that names the aporia Kant leaves open rather than a solution Kant himself provides. In relation to the cross-referenced canonical concepts, Ethical Transubstantiation is best understood as a specification of the problem of Form: where the corpus's account of Form emphasizes that "pure form" in the Kantian–ethical register must itself become materially operative as a drive, Ethical Transubstantiation names the precise site and the precise difficulty of that operativity—it is the movement from pure Form to Drive, and the quasi-miraculous character of that movement is precisely what requires theorization. The concept thus bridges the canonical pair Form/Drive: Form names the starting point (the law's purely relational, content-free structure) and Drive names the destination (a constant, non-rhythmic, materially efficacious pressure on the subject), while Ethical Transubstantiation names the conversion between them.

The concept is equally positioned in relation to the Need–Demand–Desire–Objet petit a cluster. Župančič's theoretical move argues that the Kantian aporia (pure law must become drive) is structurally homologous to the Lacanian passage from Demand to Desire via the objet petit a. Just as Demand, once filtered through the signifying apparatus, produces a remainder that cannot be absorbed by either the satisfaction of need or the appeal for love—a remainder that is the objet petit a and that installs Desire as irreducible lack—so Kant's pure form, once it must act in the phenomenal world, produces something in excess of both its formal purity and any pathological content: a surplus that is, for Župančič, structurally equivalent to surplus-enjoyment. The Ethics of Psychoanalysis canonical concept further contextualizes the stakes: Lacan's own reading of Kant in Seminar VII credits the categorical imperative with approaching the non-pathological cause of desire while simultaneously betraying it. Ethical Transubstantiation marks precisely the point where that betrayal occurs—or rather, where the necessity that produces it is first legible.

The second question that must be dealt with concerns what we might call the 'ethical transubstantiation' required by Kant's view: the question of the possibility of converting a mere form into a materially efficacious drive.

The phrase "converting a mere form into a materially efficacious drive" bears the full theoretical weight of the concept: "mere form" signals Kant's purely relational, content-free law, while "materially efficacious drive" imports the Freudian–Lacanian vocabulary of Trieb—a constant, bodily pressure—making the sentence a hinge between two entirely different theoretical registers and flagging their structural collision as the concept's very substance.
