Voltaire

By Nadia El-Masri

François-Marie Arouet — who renamed himself Voltaire, for reasons he never explained — was born in Paris in 1694 and became the most famous writer in Europe: poet, playwright, historian, pamphleteer, and the Enlightenment's supreme publicist. He was imprisoned in the Bastille twice for his verses, exiled, beaten by order of an aristocrat he had insulted (the Chevalier de Rohan, who had him thrashed by lackeys while watching from a carriage), and learned early that in the old regime, wit was dangerous and power answered criticism with force. He spent the next sixty years answering back.

Voltaire's weapon was clarity. His prose — rapid, ironic, merciless — made philosophy readable to anyone who could read, and his correspondence, some 20,000 letters, networked the Enlightenment across the continent. He praised England in the Lettres philosophiques (1734) for its liberty, its science, its commerce — and had the book condemned and burned in Paris for the comparison. He quarreled with everyone: with the Church, which he accused of fanaticism and superstition; with Rousseau, whom he called a monster; with Frederick the Great, at whose court he spent three glittering, miserable years. He was not a democrat — he preferred enlightened despots, and flattered Catherine of Russia shamelessly — but he was something rarer: a celebrity who spent his fame on other people's causes.

The great causes came late, and they made him immortal. In 1762, the Protestant merchant Jean Calas was broken on the wheel in Toulouse on a fabricated charge of murdering his son to prevent his conversion to Catholicism. Voltaire took up the case at sixty-eight, investigated it like a modern journalist, mobilized opinion across Europe, and in 1765 had the verdict posthumously reversed. He did it again for the Sirven family, again for the Chevalier de La Barre, a nineteen-year-old executed for blasphemy. The Treatise on Tolerance (1763), written amid the Calas affair, became the Enlightenment's charter: fanaticism is the enemy, reason the judge, tolerance the law. His war cry — écrasez l'infâme, "crush the infamous thing" — meant the alliance of superstition, intolerance, and clerical power.

He died in Paris in 1778, at eighty-three, returning to the capital in triumph as the Revolution's intellectual godfather gathered strength; the Church refused him burial in consecrated ground, and his friends buried him secretly in Champagne. In 1791 the Revolution transferred his remains to the Panthéon. Voltaire would have been horrified by the Terror — he believed in reform from above, not revolution from below — but the revolutionaries knew what they owed him: he had taught France to laugh at priests, to despise fanaticism, and to believe that cruelty in the name of God was the worst cruelty of all. The secular, anticlerical French Republic still speaks his language.

Impact on civilization

Voltaire made the Enlightenment a mass movement rather than a philosophers' seminar. His prose style — clear, ironic, accessible — created the model of the public intellectual: the writer as the conscience and prosecutor of society, a role every later engagé writer inherits. The Calas affair invented the modern human-rights campaign: investigation, publicity, mobilization of opinion across borders to overturn an unjust verdict — the template of Amnesty International two centuries early. The Treatise on Tolerance became the founding text of European secularism, and his war against fanaticism shaped the anticlerical character of the French Revolution and the laïcité of the French Republic. His popularization of Newton and Locke on the continent, his histories, and his 20,000-letter correspondence network made him the Enlightenment's distribution system — ideas traveled because Voltaire carried them. The principle he established — that cruelty committed in religion's name is uniquely shameful, and that tolerance is a political necessity — remains embedded in European human-rights law. He taught a continent that reason could be a weapon and laughter a form of courage.
