Categorical Imperative

The Categorical Imperative, as reconstructed in Ruda's reading of Schmid's Kantian moral rationalism, is the formal command of pure practical reason: act only on maxims that could be universalized as law for all rational beings. Its defining structural feature is that it is unconditional—it leaves "the will no discretion with respect to the opposite"—and this unconditionality is precisely what gives it the character of a law rather than a mere counsel or recommendation. It operates at the intersection of Form and Universality: as pure form (stripped of empirical content, anthropology, or theology), it imposes the requirement that any particular maxim be tested against the standard of rational universalizability, collapsing the distinction between what the will subjectively does and what reason objectively commands.

What makes this occurrence theoretically distinctive in the corpus is Ruda's argument that the categorical imperative, far from securing freedom in the conventional sense, provides the metaphysical foundation for a rationalist fatalism. Because the rational will, fully determined by reason, has no arbitrary freedom to do otherwise, subjective and objective necessity converge into an a priori identity. The categorical imperative thus names the point where autonomy—self-legislation by reason—tips over into a necessity indistinguishable from determination: the will does not choose to obey the law; insofar as it is rational, it simply is the law. This is the "necessary impossibility" that structures Schmid's system: pure rational action cannot be enacted by a finite empirical being, yet reason demands it absolutely.

This concept appears exclusively in provocations-ruda-frank-abolishing-freedom-a-plea-for-a-contemporary-use-of-fata, where it serves as the pivot of Ruda's reconstruction of Schmid's moral rationalism. Its function there is not to affirm Kantian ethics in the standard sense but to expose the fatalist underside of the categorical imperative: when Reason (cross-ref'd canonical) is understood as the sole causal ground of the will, the imperative's unconditionality removes all contingency from moral action. This connects directly to the canonical concept of Reason, where pure practical reason is the autonomous source of the moral law and the "permanent causal condition of free action" — Ruda radicalizes this by arguing that such causal completeness collapses freedom into necessity.

The categorical imperative also interfaces with the canonical concepts of Form, Universality, Autonomy, and Heteronomy. As pure Form — emptied of all empirical content (no anthropology, no physics, no theology) — it instantiates the Kantian move whereby form itself becomes normatively operative, isomorphic to what the canonical definition of Form describes as "pure form" paradoxically becoming the site where the Real makes its appearance as surplus or remainder. Its demand for Universality (that maxims be universalizable for all rational beings) rehearses the structure the canonical analysis identifies: universality is not a neutral container but a formal test that depends on reason's own self-legislation. Ruda's intervention is to show that the synthesis of Autonomy (self-given law) and this universal-formal command produces not freedom but a rationalist fatalism — a specification of the categorical imperative that repositions it as the canonical site where the Kantian liberation of the subject from Heteronomy secretly reinstates an iron necessity from within.

The unconditional command leaves the will no discretion with respect to the opposite... so that it alone brings with it that necessity which we require of a law.

The phrase "unconditional command" marks the categorical imperative's defining structure — its independence from all empirical conditions — while "leaves the will no discretion with respect to the opposite" is the precise hinge on which Ruda's fatalist reading turns: necessity here is not external compulsion (heteronomy) but the internal consequence of pure rational autonomy, making the will's "freedom" indistinguishable from determination by law.
