Cause and Effect (Kantian Moral Responsibility)

In Zupančič's reconstruction of the Kant–Constant debate, "Cause and Effect (Kantian Moral Responsibility)" names the precise logical mechanism by which Kant severs the causal chain between a speaker's truthful utterance and the consequences that follow from it. For Kant, moral responsibility is determined not by empirical outcomes but by the formal structure of the agent's act: what I do (tell the truth) and what another agent does with that truth (murder) belong to categorically distinct causal orders. Responsibility tracks the act, not the consequence, because the latter is always mediated by a second agent's free choice. To hold the truth-teller responsible for the murderer's action would be to confuse two incommensurable registers — the moral law, which governs my will, and the empirical-causal chain, which belongs to the order of nature and other wills.

This distinction is not an evasion of ethics but, in Kant's terms, its precondition. Truthfulness is what grounds the very possibility of law and social contract; any exception — however well-intentioned — introduces a self-contradiction into the moral order itself. The claim that "I cannot be held responsible for my friend's death" is therefore not an alibi but a principled philosophical consequence of the categorical structure of the moral law: my duty is to the universal form of the maxim, not to the particular outcome of any empirical scenario. Zupančič deploys this to show that Kant's "absolutism" is internally coherent and, moreover, that it opens — rather than forecloses — the Lacanian question of ethics: if the subject is answerable only to the law and not to consequences, then desire in its pure state begins to converge with duty in its pure state.

This concept appears in alenka-zupancic-ethics-of-the-real-kant-and-lacan-2000 (p. 60) as a pivotal move in Zupančič's argument that Kant's absolute prohibition on lying is philosophically rigorous rather than naively dogmatic. Within the source's argument, it functions as a clearing operation: by establishing that Kantian moral responsibility is keyed to the formal structure of the act rather than to empirical consequences, Zupančič creates the conceptual space for a Lacanian ethics of the Real, where the subject is likewise answerable to the structure of the law — and of desire — rather than to the service of goods or the calculus of outcomes. This directly anticipates the Ethics of Psychoanalysis, which, as the cross-referenced canonical makes explicit, locates guilt not in harmful consequences but in betrayal of one's own desire; the Kantian architecture here provides the formal prototype for that Lacanian inversion.

The concept also bears on Truth and the Symbolic Order as cross-referenced canonicals. Truth, for Kant in Zupančič's reading, is not a contingent value to be traded against other goods but the condition of possibility for law and contract — that is, for the Symbolic Order as such. Just as the Symbolic Order is structurally non-negotiable (the subject is authored by it, not the other way around), so Kantian truthfulness cannot be suspended by particular circumstances without self-contradiction. The concept thus extends the logic of Universality and Duty (Kantian) — any exception introduced by Particularism (e.g., "I may lie to save my friend") undermines the universal ground on which all obligation rests. In this sense, "Cause and Effect (Kantian Moral Responsibility)" is a specification of the Duty (Kantian) canonical, showing precisely how Kant's formalism handles the gap between the subject's act and the empirical chain of events — a gap that Lacan will later recast as the gap between the subject of enunciation and the Symbolic Order's consequences.

there is no necessary connection between my answer to the murderer's question and his subsequent actions. Thus, if I tell the truth, I cannot be held responsible for my friend's death.

The phrase "no necessary connection" is theoretically loaded because it invokes the Kantian categorical distinction between the moral and the empirical-causal orders: "necessary connection" is precisely what Hume and Kant associate with causal law in the domain of nature, and Kant's move is to deny that this natural-causal necessity reaches back to determine the moral evaluation of the first agent's act. The consequence — "I cannot be held responsible" — follows not as a dodge but as a strictly formal entailment of this separation, making responsibility a function of the will's relation to the moral law, not of the chain of events in the world.
