Voltaire 1694 – 1778

Voltaire (1694 – 1778) was a French philosopher of the Modern era, associated with Enlightenment.

Francois-Marie Arouet, known by his pen name Voltaire, was a French Enlightenment writer, historian, and philosopher famous for his wit and his advocacy of civil liberties. He authored more than seventy works across virtually every literary form, including the satirical novella Candide and the Philosophical Dictionary. He was a fierce critic of religious dogma, absolute monarchy, and clerical authority, and a defender of freedom of speech, religious tolerance, and the separation of church and state. His correspondence comprises some twenty thousand letters, and his ideas profoundly shaped the French Revolution and modern liberal political thought. He spent much of his life in exile or near-exile due to his outspoken criticism of authority.

Voltaire (the pen name of François-Marie Arouet, 1694–1778) was the most influential French philosophical writer of the eighteenth century and the central figure of the European Enlightenment. Born into a comfortable Parisian family, educated by the Jesuits, he was twice imprisoned in the Bastille for his writings and spent most of the 1750s and 1760s at Ferney, on the French-Swiss border, from which he could escape across the border on short notice.

Voltaire wrote in every genre the eighteenth century recognized: tragedies, epic poetry, philosophical letters, history, contes philosophiques, encyclopedia entries, and one of the most extensive correspondences in literary history. The Letters Concerning the English Nation (1733) presented English political and religious life as a model for French reform. The Philosophical Dictionary (1764) is a sustained encyclopedic attack on intolerance, superstition, and ecclesiastical authority. Candide (1759) — written in the wake of the Lisbon earthquake — is the canonical literary demolition of Leibnizian theological optimism.

Voltaire's enduring causes were religious toleration, freedom of expression, and the reform of judicial cruelty; his interventions in the Calas and Sirven cases successfully overturned miscarriages of justice. His running quarrel with Rousseau frames much of late Enlightenment political philosophy. He returned to Paris in 1778, was treated as a returning hero, and died there at eighty-three.

    It is very remarkable, that in France, where there is but one religion, the sauces are infinitely varied, whilst in England, where the different sects are innumerable, there is, we may say, but one single sauce. Melted butter, in English cookery, plays nearly the same part as the Lord Mayor's coach at civic ceremonies, calomel in modern medicine, or silver forks in the fashionable novels. Melted butter and anchovies, melted butter and capers, melted butter and parsley, melted butter and eggs, and melted butter for ever: this is a sample of the national cookery of this country.
