Mediaeval Socialism — Inside the Classic

The Schoolmen’s Delicate Logic

Jarrett devotes considerable attention to the Scholastic tradition, especially Thomas Aquinas. He notes that Aquinas’s nuanced position—that private property is not contrary to natural law but is a human addition to it—was often reduced to half-truths by later partisans. Some quoted Aquinas’s remark that “by nature all things were in common,” while others seized on his assertion that socialist organisation was impracticable in his own age. Jarrett insists that the full Scholastic argument, with its “perfect adjustment of every step,” resists such cherry-picking. The Schoolmen, he writes, viewed social questions “in the refracted light of theology and philosophy,” producing a system that was both intellectually delicate and hardy. This section shows how medieval thinkers built a framework that later centuries would both exploit and misunderstand.

Feudal Contracts and Legal Minds

The lawyers, Jarrett explains, approached property from a different angle than the theologians. They worked within the feudal system, which he describes as a series of contractual relationships based on reciprocal rights and duties. Using William the Conqueror’s Domesday Book as a typical example, he traces how land was parcelled out from king to baron to retainer, each level bound by specific obligations. The legalists, whether civil or canon, developed theories of ownership that depended on these historical arrangements. Jarrett emphasises that both theologians and lawyers appealed to what they considered authentic facts about the origin of property—but those facts were themselves shaped by the feudal context. The lawyers’ angle, he suggests, produced a more pragmatic, less abstract set of arguments about ownership and justice.

Selective Quotation and Social Revolt

Jarrett shows how medieval authorities were wielded in practical conflicts. He points to the friars described by Wyclif and Langland, who led peasants in the 1381 revolt against “over-legalised feudalism.” These rebels quoted Aquinas on common ownership while ignoring his cautions about practicability. Jarrett’s own language is telling: “Truth is blinding in its brilliance. Half-truths are easy to see, and still easier to explain.” The book thus traces a pattern of selective citation that continues into modern debates. Jarrett does not endorse any particular medieval thinker’s position; instead, he documents how their ideas were mobilised by different parties. This section underscores the tension between abstract theory and political use, a theme that runs through the entire work.

Readers should approach Mediaeval Socialism as a study of arguments rather than a history of movements. Jarrett is less interested in whether medieval society was socialist than in how medieval thinkers reasoned about property, community, and obligation. The book rewards attention to its distinctions—between theologians and lawyers, between full theories and quoted fragments, between abstract principle and feudal practice. Those expecting a narrative of proto-socialist uprisings will find instead a careful analysis of intellectual traditions that later centuries would mine for ammunition.

Reading about scholastic debates over property reminded me of sitting in my grandfather’s study, tracing his marginalia in an old paperback. He’d underlined Aquinas next to notes about stewardship versus dominion. Then I found Medieval Europe — Themes and Context on his shelf, and that same quiet argument—how ownership feels more like borrowed time than possession—returned, unhurried, like dust settling after turning a page.
