The ideas of these English philosophers were destined to exercise a far greater influence upon France than upon England. They found delighted admirers among the nobility, ardent disciples among the bourgeoisie, and eloquent apostles in Voltaire, Diderot, and Rousseau.

Without a doubt, the foremost figure in the intellectual world of the eighteenth century was François Marie Arouet, or, as he called himself, François M. A. de Voltaire (1694-1778). Even from his boyhood he had been a clever hand at turning verses, and had fully appreciated his own cleverness. His businesslike father did not enjoy the boy's poetry, especially if it was written when young François should have been studying law. But François had a mind of his own; he liked to show his cleverness in gay society and relished making witty rhymes about the foibles of public ministers or the stupidity of the prince regent of France.

His sharp tongue and sarcastic pen were a source of constant danger to
Voltaire. For libel the regent had him imprisoned a year in the
Bastille. Some years later he was beaten by the lackeys of an offended
nobleman, again sent to the Bastille, and then exiled three years in
England.

At times he was the idol of Paris, applauded by philosophes and petted by the court, or again he would be a refugee from the wrath of outraged authorities. For a great part of his life he resided at Cirey in Lorraine,—with his mistress, his books, his half-finished plays, and his laboratory—for Voltaire, like all philosophes, had to play at science. Here he lived in constant readiness to flee over the border if the king should move against him. For a time he lived in Germany as the protégé of Frederick the Great, but he treated that irascible monarch with neither tact nor deference, and soon left Berlin to escape the king's ire. He visited Catherine the Great of Russia. He also lived at Geneva for a while, but even there he failed to keep peace with the magistrates.

Such conflicts with established authority only increased his fame. Moreover, his three years' exile in England (1726-1729) had been of untold value, for they had given him a first-hand acquaintance with English rationalism. He had been brought up to discount religious "superstition" but the English thinkers provided him with a well- considered philosophy. Full of enthusiasm for the ideas of his English friends, he wrote Letters on the English—a triumph of deistic philosophy and sarcastic criticism of church and society.

The opinions which Voltaire henceforth never ceased to expound had long been held by English rationalists. He combined (1) admiration for experimental science with (2) an exalted opinion of his own ability to reason out the "natural laws" which were supposed to lie at the base of human nature, religion, society, the state, and the universe in general. (3) He was a typical Deist, thinking that the God who had made the myriad stars of the firmament and who had promulgated eternal laws for the universe, would hardly concern Himself with the soul of Pierre or Jean. To him all priests were impostors, and sacraments meaningless mummery, and yet he would not abolish religion entirely. Voltaire often said that he believed in a "natural religion," but never explained it fully. Indeed, he was far more interested in tearing down than in building up, and disposed rather to scoff at the priests, teachings, and practices of the Catholic Church than to convert men to a better religion. (4) Likewise in his criticism of government and of society, he confined himself mostly to bitter denunciations of contemporaneous conditions, without offering a substitute or suggesting practical reforms. His nearest approach to the practical was his admiration for English institutions, but he never explained how the "liberties" of England were to be transplanted into France.

Voltaire was not an acutely original thinker. Nevertheless, his innumerable tragedies, comedies, histories, essays, and letters established his reputation as the most versatile and accomplished writer of his age. But all the "hundred volumes" of Voltaire are rarely read today. They are clever, to be sure, witty, graceful,—but admittedly superficial. He thought that he could understand at a glance the problems upon which more earnest men had spent their lives; he would hurriedly dash off a tragedy, or in spare moments write a pretentious history. He was not always accurate but he was always clever.

Let us remember him as, at the age of eighty-four, he pays a famous visit to Paris,—a sprightly old man with wrinkled face, and with sharp old eyes peering out from either side of the long nose, beaming with pride at the flattery of his admirers, sparkling with pleasure as he makes a witty repartee. The ladies call him a most amusing old cynic. Cynic he is, and old. His life work has been scoffing. Yet Voltaire is unquestionably the intellectual dictator of Europe. His genius for satire and his fearless attacks on long-standing abuses have made him hated, and feared, and admired. He has given tone and character to the Old Régime.

[Sidenote: Diderot and the Encyclopedists]

Voltaire was not alone in the work of spreading discontent. Less famous but hardly less brilliant or versatile, was Denis Diderot (1713-1784). His great achievement was the editing of the Encyclopedia. The gathering of all human knowledge into one set of volumes—an encyclopedia—had been for generations a favorite idea in Europe. Diderot associated with himself the most distinguished mathematicians, astronomers, scientists, and philosophers of the time in the compilation of a work which in seventeen volumes [Footnote: Not counting pictorial supplements.] undertook to summarize the latest findings of the scholarship of the age. Over four thousand copies had been subscribed when the Encyclopedia appeared in 1765. It proved to be more than a monument of learning: it was a manifesto of radicalism. Its contributors were the apostles of rationalism and deism, [Footnote: Some went even further and practically denied the existence of God.] and their criticism of current ideas about religion, society, and science won many disciples to the new ideas.
