Necessity and Contingency

Necessity and Contingency, as it appears across these two sources, names a structural pair that organizes the relationship between freedom, responsibility, and the Real in Lacanian-inflected thought. In the first occurrence (Ruda, drawing on Luther), necessity is split into two radically different registers: necessitas immutabilitatis (necessity as immutability — what cannot be otherwise) and necessitas coactionis (necessity as compulsion — being forced from without). This distinction is theoretically decisive because it refuses to collapse determinism into mere external constraint. Freedom, on this account, is not opposed to necessity but is located within it: the subject is most responsible precisely for what it cannot change, since the immutability of its condition does not excuse it but rather constitutes the very ground of its ethical position. This is a structural anticipation of the Freudian logic of unconscious responsibility — one is answerable for what one did not consciously choose.

In the second occurrence (Zupančič), the necessity/contingency pair is mobilized through Lacan's modal logic of the sexual relation. Contingency names what "stops not being written" — the fragile, non-necessary inscription of a relation — while necessity names what "doesn't stop being written," a foreclosure of the gap by which impossibility is replaced with fixity. The amorous nickname and the Marxist concept of class struggle are offered as examples of a "new signifier" that names minimal contingent difference without collapsing it into necessity. The danger is precisely the shift from contingency to necessity: once the gap (the impossibility of the sexual relation) is covered over by a necessary inscription, the Event is foreclosed and the Real is sutured. Necessity, here, is not a ground but a symptom — the disappearance of the very impossibility that sustained the structure.

In provocations-ruda-frank-abolishing-freedom-a-plea-for-a-contemporary-use-of-fata, the necessity/contingency distinction functions as a theological-philosophical preparation for a structural account of predestination and unconscious responsibility. It intersects with the cross-referenced concepts of Freedom, Guilt and Responsibility, and Subject: rather than freedom being the opposite of necessity, the subject is constituted through an immutable necessity it must nonetheless own, anticipating the Freudian-Lacanian logic whereby the barred subject ($) is responsible for what exceeds its conscious will. This aligns with the canonical account of the Subject as the structural locus of lack — not an agent who could have done otherwise, but one whose very constitution entails answerability.

In what-is-sex-alenka-zupancic, the same pair is deployed within the modal logic of the sexual relation and the theory of the Event. Here it cross-references Repetition, Foreclosure, and Capacity of Naming. Necessity in Zupančič's sense is the modal fate of contingency once a signifier ceases to name a minimal difference and instead sutures impossibility into fixity — a foreclosure of the gap the Real opens. The "new signifier" (Capacity of Naming) must keep contingency alive rather than domesticate it into necessity. This is the opposite movement from Ruda: where Ruda rehabilitates necessity (as immutability) as ethically generative, Zupančič warns against necessity (as the foreclosure of contingency) as the collapse of the Event. Together, the two occurrences map out the full structural ambivalence of the necessity/contingency pair within Lacanian theory.

What Is Sex?Alenka Zupančič · 2017 (p.148)

the minimal difference (contingency) on account of which my lover keeps reminding me of himself... the shift from 'stops not being written' to 'doesn't stop being written.' What happens in this shift is that the impossibility disappears, and is simply replaced by necessity

The quote is theoretically loaded because it maps directly onto Lacan's four modal formulas of the sexual relation: "stops not being written" (contingency) names the fragile, non-necessary status of love's inscription, while "doesn't stop being written" (necessity) names its fatal ossification — the moment impossibility, which is constitutive of the Real, is foreclosed and replaced by a fixity that sutures the gap. The phrase "impossibility disappears" is the critical move: it signals not resolution but foreclosure, the very operation that the concept of Necessity and Contingency is designed to resist.
