The English Letters: Liberty, Newton, and Locke

Voltaire’s <em>Letters concerning the English Nation</em> - the book that used England as a mirror to shame France, praising its religious tolerance, its commerce, its liberty, and above all the empiricism of Locke and the science of Newton as models for a rational, free society.

From the lesson

In 1726 the young Voltaire, having been beaten by a nobleman’s servants and then imprisoned in the Bastille for daring to demand satisfaction, fled to England. The nearly three years he spent there transformed him. He learned English, read Locke and Newton, met writers and scientists, watched Parliament and the stock exchange, and marvelled at a society that seemed to run on principles the opposite of France’s. When he returned, he distilled his observations into the Letters concerning the English Nation (published in English in 1733, and in French as the Lettres philosophiques in 1734). On the surface it is a traveller’s report on English religion, politics, commerce, and thought. In reality it is one of the most effective works of criticism ever written, because Voltaire praises England precisely where France is weakest. Every compliment to English liberty, tolerance, and reason is a silent accusation against French absolutism, intolerance, and superstition. The French authorities understood exactly what he was doing: the book was condemned and publicly burned, and Voltaire had to flee Paris again.

Two things about England struck Voltaire most, and he linked them brilliantly: religious diversity and commerce. In France, one intolerant church claimed a monopoly on truth and the state enforced it; in England, a multitude of sects - Anglicans, Presbyterians, Quakers, Jews, and more - lived and traded side by side without cutting one another’s throats. Voltaire saw that this peace was produced not by everyone agreeing but by there being too many disagreements for any one party to dominate. And he located the emblem of this tolerant order not in a cathedral but in the Royal Exchange, London’s great trading floor, where men of every faith did business together and reserved the word ‘infidel’ only for those who went bankrupt. Commerce, he suggested, is a quiet solvent of fanaticism: at the exchange a Jew, a Muslim, and a Christian care only whether a partner is solvent and honest, not how he prays. Where trade flourishes and sects multiply, tolerance follows as a matter of practical necessity.

If Locke gave Voltaire a philosophy, Newton gave him a hero and a model of what human reason could achieve. In the Letters Voltaire introduced French readers to Newtonian physics - the law of universal gravitation, the analysis of light - at a time when French science was still dominated by Descartes’s rival system of vortices. Voltaire was dazzled less by any single result than by Newton’s method: patient observation, mathematical rigour, and a refusal to invent causes beyond what the evidence required. Here was reason that did not spin fantasies but measured the heavens and got the right answer. Newton became for Voltaire the very emblem of the Enlightenment - proof that humanity, using experience and mathematics rather than authority and dogma, could read the laws of the universe itself. He devoted years to popularizing Newton (aided by his brilliant companion Émilie du Châtelet, who translated the Principia into French), because he saw in Newtonian science the template for all rational inquiry: observe, measure, reason from the evidence, and claim no more than you can show.

This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.

What you'll be able to recall

You learned that Voltaire’s Letters concerning the English Nation held up English tolerance, commerce, and liberty, and the empiricism of Locke and the physics of Newton, as a model for France - implicitly indicting French absolutism and superstition. Explain what he admired in England and why the book was so subversi…
