III. The Enlightenment’s Rhetorical Strategy
The Enlightenment’s thinkers were not, for the most part, fools. Many were genuinely intelligent, some were mathematically gifted, and a few made genuine contributions to human knowledge. But they were charlatans, and the movement as a whole succeeded through the effectiveness of its propaganda instead of the quality of the arguments it presented.
The first and most consequential rhetorical move was the appropriation of “reason” and “science” as assumed identities. This false appropriation had a precedent. The groundwork was laid four centuries earlier by Petrarch, who invented the ahistorical concept of the Dark Ages by inverting the Christian understanding of history. The traditional view held throughout Christendom was that Jesus Christ is the light of the world, and that His coming had illuminated the darkness of paganism. The Roman world, for all its many achievements, was deemed to have been shrouded in spiritual blindness until the Gospel dispelled the shadows of sin. Petrarch reversed this imagery. For him, the classical Roman world was the light and the civilization of Cicero, Virgil, and Seneca represented the pinnacle of human achievement. The centuries following Rome’s fall were the darkness, not because paganism had not yet been entirely displaced, but because classical learning had been disrupted.
This disruption was real enough; the invasions that ended the Western Empire shattered the infrastructure of civilization and scattered the literary culture that Petrarch idolized. But Petrarch’s framing targeted the wrong culprit. The barbarians who destroyed Roman learning were pagans, for the most part, not Christians, while the monks who preserved what knowledge survived were almost uniformly servants of the Church. Yet in Petrarch’s telling, it was the Christian centuries that were portrayed as the problem, being an interruption and a falling away from the historical standard of human excellence as exemplified by the glory that was Rome.
The Enlightenment inherited and amplified this Italian inversion. What Petrarch had expressed as one man’s literary and aesthetic preference became, in Enlightenment hands, a comprehensive historical narrative. The Dark Ages was expanded to encompass the entire medieval period; the light that had supposedly been extinguished was identified not only with classical style, but with reason itself. The Church, which had preserved classical learning through the monasteries, which had founded the universities, which had developed logic and natural philosophy to heights the Romans never approached, was recast as the agent of darkness, the enemy of inquiry, and the suppressor of knowledge. The narrative was false in almost every particular, as medieval Europe was one of the most intellectually dynamic civilizations in human history, but it served its rhetorical purpose. It made the Enlightenment appear not as one philosophical movement among others, but as the recovery of light after a millennium of darkness, the restoration of reason following an age of superstition.
This rhetorical inversion became a tribal marker. To be for reason and light was to be for the Enlightenment; to oppose the Enlightenment was to be outdated and against reason. These identifications were asserted rather than demonstrated, repeated until they appeared to be self-evident, and relentlessly enforced through social pressure and institutional control.
The inversion was fraudulent. The classical tradition had always employed reason. Indeed, it had developed formal logic to a degree of sophistication never matched by any Enlightenment thinker. The Christian tradition had founded the universities, supported the investigation of nature, produced mathematicians and astronomers and physicians. But fraud, confidently asserted and widely repeated, can override the truth for generations, and sometimes even centuries. The Enlightenment did not earn the mantle of reason; it simply claimed it, and its claim was not effectively contested by its rivals.
The problem was that Aristotelian dialectic was designed to operate within a community of honest inquirers who shared its basic assumptions: that truth exists, that reason can apprehend it, that logical argument is the proper means of resolving disagreement. The Enlightenment rhetoricians shared none of these assumptions in practice, whatever they may have claimed in theory. They understood, as the Sophists had understood two thousand years earlier, that the mass of men are not moved by syllogisms but by appeals to their passions, their vanity, and their self-interest. Voltaire never refuted Aquinas. He mocked him, and that mockery proved far more effective than refutation because it operated on the rhetorical plane where most human persuasion actually occurs.
The second rhetorical move was the strategic use of “evidence” and “empiricism” as gestures rather than disciplines. The Enlightenment talked constantly of evidence, of observation, of testing ideas against experience. But this talk was largely decorative. The core Enlightenment commitments—the social contract, the invisible hand, the perfectibility of man, the inevitability of progress—were not derived from evidence and were not surrendered when evidence contradicted them. They were philosophical postures, immune to empirical refutation, defended by the same appeals to authority and tradition that the Enlightenment officially despised.
The Scholastic method had no defense against an opponent who refused to engage on Scholastic terms, who bypassed the dialectical arena entirely and went straight to the unlettered masses. By the time the tradition recognized what was happening, its institutional foundations in the universities and the Church had already been hollowed out, and the abstract Platonic idealism it had once held in check had returned in secular dress, more powerful and more destructive than ever.
When mathematicians at the Wistar Institute demonstrated that the Modern Synthesis could not account for observed genetic variation, the biologists did not revise their theory; they ignored the mathematicians. When economists proved that market demand curves do not behave as Smith assumed, the economics profession did not abandon supply and demand; they continued teaching it. The pattern is consistent: “evidence” and “reason” are invoked as legitimating rhetoric, but the actual conclusions are determined by other factors—institutional inertia, career incentives, ideological commitment—and the evidence is interpreted, or ignored, accordingly.
The third rhetorical move was the reframing of the debate as “faith versus reason” or “religion versus science.” This framing was tactically brilliant and substantively false. The Christian tradition had never opposed faith to reason; it had always understood faith as complementing and completing reason, by providing access to truths that reason alone could not reach but that reason could one day hope to subsequently explore and articulate. The great Scholastics were not enemies of rational inquiry; they were its most rigorous practitioners. But this false dichotomy served the Enlightenment’s purposes as it forced the tradition onto defensive ground, portrayed every defense of revealed truth as an attack on reason, and obscured the fact that the Enlightenment’s own premises were matters of unsubstantiated faith and groundless assumptions that would inevitably prove to be false over time.
The fourth rhetorical move was institutional capture. The philosophes understood that ideas propagate through institutions: universities, academies, salons, journals, publishing houses. Control the institutions, and you control the formation of the next generation. The Enlightenment pursued this strategy with patience and persistence. Chairs were endowed, curricula were shaped, journals were founded, academies were captured or created. By the nineteenth century, the infrastructure of intellectual respectability was almost entirely in Enlightenment hands. To dissent was to be excluded—not refuted, simply excluded, denied publication, denied respectability, and denied an audience.
As noted in the previous section, this capture was enabled by the usury revolution. Ideas require patrons; patrons require capital; capital, after the legitimization of usury and the creation of central banking, could be generated almost without limit by those who controlled the mechanisms of credit. The tradition operated on real savings, actual production, and honest money. Its opponents had discovered leverage, deficit spending, and the long game that patient capital makes possible. The rhetorical victory was underwritten by a financial revolution that gave the Enlightenment vast resources that the traditionalists could not hope to match.
