region.
Richard Holmes supports the anagrammatic derivation of the name, but adds that a writer such as Voltaire would have intended it to also convey connotations of speed and daring. These come from associations with words such as (acrobatics on a trapeze or horse), ''volte-face'' (a spinning about to face one's enemies), and ''volatile'' (originally, any winged creature). "Arouet" was not a noble name fit for his growing reputation, especially given that name's resonance with ("to be beaten up") and (a ''débauché'').
In a letter to
Jean-Baptiste Rousseau in March 1719, Voltaire concludes by asking that, if Rousseau wishes to send him a return letter, he do so by addressing it to Monsieur de Voltaire. A postscript explains: "", ("I was so unhappy under the name of Arouet that I have taken another, primarily so as to cease to be confused with the poet Roi.") This probably refers to
Adenes le Roi, and the 'oi' diphthong was then pronounced like modern 'ouai', so the similarity to 'Arouet' is clear, and thus, it could well have been part of his rationale. Voltaire is known also to have used at least 178 separate pen names during his lifetime.

Seeking redress, Voltaire challenged Rohan to a duel, but the powerful Rohan family arranged for Voltaire to be arrested and imprisoned without trial in the Bastille on 17 April 1726.
Fearing indefinite imprisonment, Voltaire asked to be exiled to England as an alternative punishment, which the French authorities accepted. On 2 May, he was escorted from the Bastille to

However, Franklin was merely a visitor at the time Voltaire was initiated, the two only met a month before Voltaire's death, and their interactions with each other were brief.
Death and burial
In February 1778, Voltaire returned to Paris for the first time in over 25 years, partly to see the opening of his latest tragedy,
''Irene''. The five-day journey was too much for the 83-year-old, and he believed he was about to die on 28 February, writing "I die adoring God, loving my friends, not hating my enemies, and detesting superstition." However, he recovered, and in March he saw a performance of ''Irene'', where he was treated by the audience as a returning hero.
He soon became ill again and died on 30 May 1778. The accounts of his deathbed have been numerous and varying, and it has not been possible to establish the details of what precisely occurred. His enemies related that he repented and accepted the last rites from a Catholic priest, or that he died in agony of body and soul, while his adherents told of his defiance to his last breath. According to one story of his last words, when the priest urged him to renounce Satan, he replied, "This is no time to make new enemies."
Because of his well-known criticism of the Church, which he had refused to retract before his death, Voltaire was denied a Christian burial in Paris, but friends and relations managed to bury his body secretly at the in

'' (1751), and his ''
Essay on the Customs and the Spirit of the Nations'' (1756). He broke from the tradition of narrating diplomatic and military events, and emphasized customs, social history and achievements in the arts and sciences. The ''Essay on Customs'' traced the progress of world civilization in a universal context, rejecting both nationalism and the traditional Christian frame of reference. Influenced by
Bossuet's ''Discourse on Universal History'' (1682), he was the first scholar to attempt seriously a history of the world, eliminating theological frameworks, and emphasizing economics, culture and political history. He treated Europe as a whole rather than a collection of nations. He was the first to emphasize the debt of medieval culture to Middle Eastern civilization, but otherwise was weak on the Middle Ages. Although he repeatedly warned against political bias on the part of the historian, he did not miss many opportunities to expose the intolerance and frauds of the church over the ages. Voltaire advised scholars that anything contradicting the normal course of nature was not to be believed. Although he found evil in the historical record, he fervently believed reason and expanding literacy would lead to progress.
Voltaire explains his view of historiography in his article on "History" in Diderot's ''

In general, his criticism and miscellaneous writing show a similar style to Voltaire's other works. Almost all of his more substantive works, whether in verse or prose, are preceded by prefaces of one sort or another, which are models of his caustic yet conversational tone. In a vast variety of nondescript pamphlets and writings, he displays his skills at journalism. In pure literary criticism his principal work is the ''
Commentaire sur Corneille'', although he wrote many more similar works—sometimes (as in his ''Life and Notices of Molière'') independently and sometimes as part of his ''Siècles''.
Voltaire's works, especially his private letters, frequently urge the reader: "", or "crush the infamous". The phrase refers to contemporaneous abuses of power by royal and religious authorities, and the superstition and intolerance fomented by the clergy. He had seen and felt these effects in his own exiles, the burnings of his books and those of many others, and in the atrocious persecution of

Her interpretation does capture the spirit of Voltaire's attitude towards Helvétius; it had been said Hall's summary was inspired by a quotation found in a 1770 Voltaire letter to an Abbot le Riche, in which he was reported to have said, "I detest what you write, but I would give my life to make it possible for you to continue to write." Nevertheless, scholars believe there must have again been misinterpretation, as the letter does not seem to contain any such quote.
Voltaire's first major philosophical work in his battle against "" was the ''Traité sur la tolérance'' (''

, concluding by stating that "when one finds a beautiful woman completely naked, it is not for the purpose of massacring her." Voltaire meant for this argument to bolster one of his anti-Catholic tracts. In a letter to Frederick the Great, dated 5 January 1767, he wrote about Christianity:
In ''La bible enfin expliquée'', he expressed the following attitude to lay reading of the Bible:
It is characteristic of fanatics who read the holy scriptures to tell themselves: God killed, so I must kill; Abraham lied, Jacob deceived, Rachel stole: so I must steal, deceive, lie. But, wretch, you are neither Rachel, nor Jacob, nor Abraham, nor God; you are just a mad fool, and the popes who forbade the reading of the Bible were extremely wise.

However, Voltaire also acknowledged the self-sacrifice of Christians. He wrote: "Perhaps there is nothing greater on earth than the sacrifice of youth and beauty, often of high birth, made by the gentle sex in order to work in hospitals for the relief of human misery, the sight of which is so revolting to our delicacy. Peoples separated from the Roman religion have imitated but imperfectly so generous a charity." Yet, according to

For example, in Voltaire's ''A Philosophical Dictionary'', he wrote of Jews: "In short, we find in them only an ignorant and barbarous people, who have long united the most sordid avarice with the most detestable superstition and the most invincible hatred for every people by whom they are tolerated and enriched."

points to Voltaire's remarks (for instance, that the Jews were more tolerant than the Christians) in the ''Traité sur la tolérance'' and surmises that "Voltaire struck at the Jews to strike at Christianity". Whatever anti-semitism Voltaire may have felt, Gay suggests, derived from negative personal experience.
Arthur Hertzberg, a
Conservative Rabbi, claims that Gay's second suggestion is untenable, as Voltaire himself denied its validity when he remarked that he had "forgotten about much larger bankruptcies through Christians". However, Bertram Schwarzbach's far more detailed studies of Voltaire's dealings with Jewish people throughout his life concluded that he was anti-biblical, not anti-semitic. His remarks on the Jews and their "superstitions" were essentially no different from his remarks on Christians.
Voltaire said of the Jews that they "have surpassed all nations in impertinent fables, in bad conduct and in barbarism. You deserve to be punished, for this is your destiny." He further said, "They are, all of them, born with raging fanaticism in their hearts, just as the Bretons and the Germans are born with blond hair. I would not be in the least bit surprised if these people would not some day become deadly to the human race."

In his ''
Essay on the Manners and Spirit of Nations'' (published 1756), Voltaire deals with the history of Europe before Charlemagne to the dawn of the age of Louis XIV, and that of the colonies and the East. As a historian, he devoted several chapters to Islam, Voltaire highlighted the Arabian, Turkish courts, and conducts.
Here he called Mohammed a "poet", and stated that he was not an illiterate. As a "legislator", he "changed the face of part of Europe
ndone half of Asia." In chapter VI, Voltaire finds similarities between Arabs and ancient Hebrews, that they both kept running to battle in the name of God, and sharing a passion for the spoils of war. Voltaire continues that, "It is to be believed that Mohammed, like all enthusiasts, violently struck by his ideas, first presented them in good faith, strengthened them with fantasy, fooled himself in fooling others, and supported through necessary deceptions a doctrine which he considered good." He thus compares "the genius of the Arab people" with "the genius of the ancient Romans".

To whom could I with more propriety inscribe a satire on the cruelty and errors of a false prophet, than to the vicar and representative of a God of truth and mercy?" His view was modified slightly for ''Essai sur les Moeurs et l'Esprit des Nations'', although it remained negative.

According to David Allen Harvey, Voltaire often invoked racial differences as a means to attack religious orthodoxy, and the Biblical account of creation. Other historians, instead, have suggested that Voltaire's support for polygenism was more heavily encouraged by his investments in the French
Compagnie des Indes and other colonial enterprises that engaged in the slave trade.

Comte de Lally was executed for treason in 1766, Voltaire wrote a 300-page document in his defense. Subsequently, in 1778, the judgment against de Lally was expunged just before Voltaire's death. The Genevan Protestant minister Pomaret once said to Voltaire, "You seem to attack Christianity, and yet you do the work of a Christian." Frederick the Great noted the significance of a philosopher capable of influencing judges to change their unjust decisions, commenting that this alone is sufficient to ensure the prominence of Voltaire as a humanitarian.

believed that France had erred gravely by not following the path forged by Voltaire instead of Rousseau. Most architects of modern America were adherents of Voltaire's views. According to Will Durant:
Voltaire and Rousseau
Voltaire's junior contemporary Jean-Jacques Rousseau commented on how Voltaire's book ''
Letters on the English'' played a great role in his intellectual development. Having written some literary works and also some music, in December 1745 Rousseau wrote a letter introducing himself to Voltaire, who was by then the most prominent literary figure in France, to which Voltaire replied with a polite response. Subsequently, when Rousseau sent Voltaire a copy of his book ''

'', Voltaire stated:
Voltaire quipped that the first half of ''Julie'' had been written in a brothel and the second half in a lunatic asylum. In his ''Lettres sur La Nouvelle Heloise'', written under a pseudonym, Voltaire criticized Rousseau's grammatical mistakes:
In reviewing Rousseau's book ''
Emile'', Voltaire dismissed it as "a hodgepodge of a silly wet nurse in four volumes, with forty pages against Christianity, among the boldest ever known." He expressed admiration for the section titled ''Profession of Faith of the Savoyard Vicar'', calling it "fifty good pages ... it is regrettable that they should have been written by ... such a knave." He went on to predict that ''Emile'' would be forgotten within a month.
In 1764, Rousseau published ''Lettres de la montagne'' on religion and politics. In the fifth letter he wondered why Voltaire had not been able to imbue the Genevan councilors, who frequently met him, "with that spirit of tolerance which he preaches without cease, and of which he sometimes has need". The letter continued with an imaginary speech in the voice of Voltaire, acknowledging authorship of the heretical book ''Sermon of the Fifty'', which the real Voltaire had repeatedly denied.
In 1772, when a priest sent Rousseau a pamphlet denouncing Voltaire, Rousseau responded by defending his rival:
In 1778, when Voltaire was given unprecedented honors at the
Théâtre-Français, an acquaintance of Rousseau ridiculed the event. This was met by a sharp retort from Rousseau:
On 2 July 1778, Rousseau died one month after Voltaire. In October 1794, Rousseau's remains were moved to the Panthéon near the remains of Voltaire.

as a static and oppressive force useful only on occasion as a counterbalance to the rapacity of kings, although all too often, even more rapacious itself. Voltaire distrusted democracy, which he saw as propagating the idiocy of the masses. Voltaire long thought only an enlightened monarch could bring about change, given the social structures of the time and the extremely high rates of illiteracy, and that it was in the king's rational interest to improve the education and welfare of his subjects. But his disappointments and disillusions with Frederick the Great changed his philosophy somewhat, and soon gave birth to one of his most enduring works, his novella ''

quietism: "It is up to us to cultivate our garden." His most polemical and ferocious attacks on intolerance and religious persecutions indeed began to appear a few years later. ''Candide'' was also burned, and Voltaire jokingly claimed the actual author was a certain 'Demad' in a letter, where he reaffirmed the main polemical stances of the text.
