France appears in the book not as a single, fully described setting but as a revealing point of comparison: its climate, laws, religious politics, and cultural fashions help illustrate how material conditions and public opinion shape civic life. The examples range from the practical differences between Parisian and southern homes to the limits of royal edicts, the risks of theological intolerance, and the pressures contemporary taste places on artists. Together they make France a test case for the book’s concern with the relation between law, morality, and luxury.

Climate, Consumption, and Domestic Life

Climate gives the comparison its concrete starting point. In Paris and London, people seek homes that are warm and comfortable; in Madrid, the narrator contrasts grand salons with windows that do not close and sleeping quarters described as little more than a hole. The point is not that magnificence is absent in warmer places, but that the demands of habitation differ: where the air presents less danger, buildings can privilege display over protection. France thus enters a wider account of how material needs direct what people build and value.

The same climatic argument applies to clothing and food. In places with sudden, violent seasonal changes, clothes may be both simple and useful; where clothing serves primarily for adornment, conspicuousness can replace utility. The book contrasts gold-embroidered garments worn in Naples with the more protective clothing required in harsher conditions. It also argues that diet depends on what different climates produce and on how much food people need. Vegetables are described as nutritious and flavorful in Italy but comparatively poor in nourishment in France, where they are still costly to cultivate. The wheat comparison extends the argument: Barbary wheat yields more flour than French wheat, and French wheat more than wheat from northern countries. These examples make climate an influence on both everyday consumption and the resources a society can draw from its land.

Law, Opinion, and Public Morality

France also illustrates the limits of law when it tries to command public opinion. The book argues that a people’s opinions arise from its constitution and that legislation helps give public morality its form. When legislation loses strength, morality degenerates; a censor’s judgment cannot restore what weakened laws have failed to sustain. Censorship can preserve moral opinion while it remains sound, but it cannot revive it once its foundations have collapsed.

An example from France shows how a public judgment can succeed where a direct prohibition does not. The practice of using seconds in duels had become extreme. A royal edict ridiculed those who called upon seconds as cowards, and this judgment anticipated public opinion so effectively that it settled the practice. A later attempt by edict to brand duelling itself as cowardly failed: because common opinion did not share that judgment, the public disregarded the ruling. The contrast is precise. An authority can give decisive expression to an opinion that is ready to prevail, but it cannot simply legislate a new opinion into existence.

The censorship’s role is therefore not to impose morality by force, but to represent and guide a judgment already held, or still unsettled, among the public. The book contrasts this capacity with the Romans and the Spartans, whose methods of giving public opinion institutional expression are described as an art lost by modern societies. France’s duel edicts belong to this larger inquiry into the boundary between law and opinion: authority is effective when it moves with public judgment, and impotent when it tries to outrun it.

Religious Toleration and Sovereignty

France is also invoked in an argument about the political consequences of religious intolerance. The book maintains that theological intolerance cannot be separated from civil intolerance. When a religion treats those outside it as condemned, peaceful coexistence becomes unstable; once that religious division gains civil force, priests rather than the Sovereign become the real masters, leaving rulers as their ministers. The dispute is consequently not only theological. It determines whether political authority remains with the civil community or passes into clerical hands.

In the absence of a single national religion, the book argues that religions should be tolerated if they tolerate others and their doctrines do not conflict with the duties of citizenship. A belief that salvation is possible only within one church is treated as incompatible with a state that is not itself a church and a prince who is not a pontiff. The text invokes Henry IV’s reported conversion to the Roman religion as a reason that an honest person, and especially a reasoning prince, ought to leave it. France supplies the political setting for this warning: religious exclusivity, if granted civil authority, threatens the Sovereign’s independence in temporal affairs.

Cultural Fashion and Artistic Judgment

In its account of luxury, the book turns from domestic objects to artistic production. Luxury is linked to moral decline, and the resulting dissolution of morals is said to corrupt taste in turn. Artistic judgment is not presented as independent of society: artists seek the applause of contemporaries, so the prevailing fashion can shape what they make and what audiences are prepared to value.

The account describes a time when learning is fashionable, youth directs taste, and liberty is subject to those who constrain it. Under those conditions, major achievements in dramatic poetry may be condemned while distinguished music is neglected. An artist may lower the ambition of the work to meet the age’s preferences, producing mediocre pieces that win immediate admiration instead of pursuing sublime work whose recognition might come only after the artist’s death. Voltaire is named as an example of a writer who, the text suggests, could testify to the beauties sacrificed to false delicacy and to the cost of a culture devoted to gallantry and trifling concerns.

The same argument is sharpened through the painters Carle and Pierre Vanloo and the sculptor Pigal. Their abilities, as the book represents them, might have served sacred or public art; instead, the painters’ work is described as liable to be diverted to the decoration of a coach with lascivious images. The contrast is between the purpose an artist’s talent could serve and the uses encouraged by contemporary demand. France is thus not merely a place where art is produced: it is part of a cultural environment in which fashionable approval can redirect talent, diminish ambition, and narrow the standards by which work is judged.

A Place in the Book’s Argument

Across these examples, France occupies several related positions. Its wheat and vegetables make the material effects of climate legible; its duel edicts demonstrate that legislation can affirm public opinion but cannot manufacture it; and its religious and artistic examples expose the stakes of civil authority and fashionable taste. The different subjects share a concern with the distance between an institution’s declared purpose and the conditions that make it effective. A royal edict succeeds when it gives force to a judgment the public is ready to accept; it fails when it tries to dictate what the public does not believe.

This treatment also complicates any simple opposition between practical need and luxury. Houses, clothes, food, religious commitments, and artistic works all acquire meaning within specific conditions. Yet the book’s emphasis remains critical: when display displaces use, when clerical authority displaces civil sovereignty, or when fashion governs artistic ambition, public and moral life are weakened. France serves as a recurring illustration of that argument, situated between the everyday circumstances that shape a people and the laws and opinions through which it understands itself.
