Sorites Fallacy

The Sorites Fallacy, as deployed in McCormick's reconstruction of Kierkegaard's critique, designates a specific logical error — a paralogism — in which qualitative transformation is illicitly inferred from the mere accumulation of quantitative instances. The term derives from the ancient philosophical puzzle of the "heap" (Greek: sōros): if one grain of sand does not make a heap, and adding one more grain never makes a decisive difference, how does a heap ever come to exist? Applied to Kierkegaard's target, the fallacy names the rhetorical-theological move by which Christendom substitutes numerical counting (of converts, centuries, clergy) for the categorical, qualitative leap that genuine Christian faith demands. Quantity — however vast — cannot generate the eternal truth (sandhed) that Christianity claims; it can only yield a sandsynlighed, a probability, a hypothesis susceptible to empirical revision. The accumulation of evidence is precisely not the domain in which the paradox of Christianity can be resolved, because that paradox is structurally immune to empirical corroboration.

The theoretical force of naming this a "sorites" fallacy (rather than simply a rhetorical error) is to show that "preacher-prattle" (Præstesnak) operates with an internal logical structure — a paralogos — that systematically dissolves the qualitative singularity of faith into a continuum of gradual, verifiable increments. In doing so, Christendom's numerical rhetoric does not merely misrepresent Christianity; it actively undermines it by placing the Absolute in the register of accumulation and hypothesis, categories that belong to the finite and the empirical rather than to the eternal.

This concept appears in McCormick's source (samuel-mccormick-the-chattering-mind-a-conceptual-history-of-everyday-talk-unive, p.120) as part of a broader argument about the logic of idle talk and the corruption of meaning in the public sphere. The Sorites Fallacy sits at the intersection of several cross-referenced concepts: it is the mechanism by which Probabilistic Rhetoric colonizes the domain of Truth, and it is the structural error that "preacher-prattle" enacts. Crucially, in relation to the cross-referenced concept of Signification, the fallacy can be read as a failure at the level of the quilting point: instead of suturing meaning at a qualitative threshold — the paradox of Christianity, the singular leap of faith — numerical rhetoric produces an endless displacement along a quantitative chain, mistaking the accumulation of signifiers (numbers, testimonies, historical duration) for the production of a genuinely different signified. Signification's constitutive bar, the resistance between signifier and signified, is here "filled in" fraudulently by sheer volume rather than by the structural event (the point de capiton) that would properly anchor meaning.

In relation to Truth and Universality, the Sorites Fallacy marks the precise point at which a discourse that aspires to eternal, universal truth collapses into a merely statistical claim. The fallacy is not incidental but constitutive of what McCormick calls the chattering public: the Public as a discursive formation is defined precisely by its inability to sustain the qualitative distinction between truth and probability, substituting aggregation for the singular paradox that genuine signification — or genuine faith — requires. The concept is thus both an extension of the Kierkegaardian critique of the crowd and a specification of how quantitative rhetoric operates as a structurally identifiable logical error rather than a mere stylistic failing.

the paralogos in question here amounts to sorites reasoning— a habit of mind which, as we saw in chapter 2, presumes that qualitative change can issue from quantitative accumulation.

The phrase "qualitative change can issue from quantitative accumulation" is theoretically loaded because it names the precise category mistake at stake: the assumption of a continuous, gradable passage from the empirical-quantitative to the categorical-qualitative, which is exactly what the paradox of Christianity (and, structurally, any genuine signification-event) forecloses. The term "paralogos" further signals that this is not mere rhetorical bad faith but a formal logical error — a false inference built into the very grammar of Christendom's numerical self-justification.
