Many in the 18th [century] who thought democracy was absurd rejected it because they disagreed with this thesis, believing that the majority of people (even of white men) were not educable, i.e. that even with educational resources most people were born incapable of being guided by Reason and making sound political judgments. Those who believed this predicted that government by the people would collapse into absurdity, since it would be led by a parliament of fools. We get a taste of what such critics of democracy thought would happen to America in the satirical scenes in Shakespeare’s Henry VI Part 2 in which Jack Cade’s populist rebels happily kill each other and laugh about it, and believe they can end hunger by having everyone eat on the king’s tab at restaurants and making the gutters run with wine (and which is the source of the much-misunderstood “First thing we do is kill all the lawyers,” step 1 in which executing everyone who can read is their step 2) — this is what many 18th c. anti-democrats believed would happen if governing was truly done by the people.

The principle that souls of gold (i.e. souls fully capable of being educated & of wise rule) are a tiny minority, and that most humans are immutably not educable from birth, was very thoroughly absorbed into European belief, and dominated it for 2,000 years. In Dante, we see the entire structure of Hell revolve around the appetites/passions/intellect distinction. Medieval epistemology, psychology, and even ideas about medicine and plants incorporated this principle, and spun elaborate explanations for how and why different souls perceived the heavenly world (Good, Justice, Providence) better than others. Eugen Weber’s powerful history, Peasants into Frenchmen: The Modernization of Rural France, 1870-1914, shows how people in the period wrote about their own French peasants in incredibly insulting, infantilizing, quasi-bestial terms, strikingly similar to the racist language we’re used to the Age of Empires using to demean non-Europeans. Anyone who hasn’t looked at period sources will struggle to believe how ferociously confident the European majority was in the thesis that the majority of people even in their own country could never understand a book, a moral quandary, or a political proposition. Keeping the rare wise elites in charge was the only barrier between order and savagery. The fact that so many people were willing to believe in the totally mythical tragedy of the commons (yes, it’s totally invented, real peasants took great care of their commons) is one relic of how certain people were for a long time (and some still are) that most people are not capable of making the kinds of prudent, sustainable judgments necessary for custodianship of a polity.

It took a lot to get even a small radical fringe by 1750 to entertain the notion that all people–or even just all men–were created equally educable. A long survey of the causes would get unwieldy, but they include (among other things) contact with indigenous cultures in the Americas and other regions which had functional governments without European-style systems, revolutions in medicine and the understanding of the sense organs which undermined old hierarchy-enforcing ideas about how cognition and sensation functioned, second-order consequences of the rags-to-riches path opened by Renaissance courts employing scholars from any background so long as they had good Latin, and Protestantism’s second-order implication that, if people didn’t need priests as intermediaries between their prayers and God, perhaps they didn’t need aristocrats as intermediaries between them and power. But by 1750 that fringe existed, and had enough momentum to implement its experiment in the new United States, which most people who were considered sensible at the time thought would quickly degenerate into chaos, because they didn’t think most people were capable of understanding the world enough to vote sensibly, draft legislation, or serve in a congress, and that the tiny wise minority would be drowned out by the majority wanting to vote for dining on the king’s tab and killing all the lawyers.
