Early career

François Marie Arouet was born in Paris, the youngest of the five children (only three of which survived) of François Arouet (1650 — 1 January 1722), a notary who was a minor treasury official, and his wife, Marie Marguerite d'Aumart (ca. 1660 — 13 July 1701), from a noble family of the province of Poitou. Voltaire was educated by Jesuits at the Collège Louis-le-Grand (1704—1711), where he learned Latin and Greek; later in life he became fluent in Italian, Spanish and English.

By the time he left school, Voltaire had decided he wanted to be a writer, against the wishes of his father who wanted him to become a notary. Voltaire, pretending to work in Paris as an assistant to a notary, spent much of his time writing poetry. When his father found him out, he sent Voltaire to study law, this time in Caen (Normandy). Nevertheless, he continued to write, producing essays and historical studies. Voltaire's wit made him popular among some of the aristocratic families with whom he mixed. His father then obtained a job for him as a secretary to the French ambassador in the Netherlands, where Voltaire fell in love with a French Protestant refugee named Catherine Olympe Dunoyer. Their scandalous elopement was foiled by Voltaire's father and he was forced to return to France.

Most of Voltaire's early life revolved around Paris. From early on, Voltaire had trouble with the authorities for even mild critiques of the government and the Catholic Church. These activities were to result in numerous imprisonments and exiles. One satirical verse about the Régent thought to be by him led to his imprisonment in the Bastille for eleven months, until the real author came forward. While there, he wrote his debut play, ?dipe. Its success established his reputation.

The name "Voltaire"

The name "Voltaire", which the author adopted in 1718, is an anagram of "AROVET LI," the Latinized spelling of his surname, Arouet, and the initial letters of "le jeune" ("the younger"). The name also echoes in reverse order the syllables of the name of a family château in the Poitou region: "Airvault". The adoption of the name "Voltaire" following his incarceration at the Bastille is seen by many to mark Voltaire's formal separation from his family and his past.

Richard Holmes supports this derivation of the name, but adds that a writer such as Voltaire would have intended it to also convey its connotations of speed and daring. These come from associations with words such as "voltige" (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 "à rouer" ("for thrashing") and "roué" (a "débauché").

In a letter to Jean-Baptiste Rousseau (not to be confused with Jean-Jacques) 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 post-scriptum explains: "J'ai été si malheureux sous le nom d'Arouet que j'en ai pris un autre surtout pour n'être plus confondu avec le poète Roi.", which translates as, "I was so unhappy under the name d'Arouet that I took another, primarily so that I would cease to be confused with the poet Roi." This probably refers to Adenes le Roi, and the 'oi' diphthong was then pronounced as modern French pronounces 'ai', so the similarity to 'Arouet' is clear, and thus, it could well have been part of his rationale. Indeed, Voltaire is additionally known to have used at least 178 separate pen names during his lifetime.

Great Britain

The aptitude for quick, perceptive, cutting and witty critical repartee for which Voltaire is known today made him highly unpopular with some of his contemporaries, including certain members of the French aristocracy. These sharp-tongued retorts were responsible for Voltaire's exile from France, during which he resided in Great Britain.

After Voltaire retorted to an insult given him by the young French nobleman Chevalier de Rohan in late 1725, the aristocratic Rohan family obtained a royal lettre de cachet, an irrevocable and often arbitrary penal decree signed by the French King (Louis XV, in the time of Voltaire) that was often bought by members of the wealthy nobility to dispose of undesirables. They then used this warrant to force Voltaire into imprisonment in the Bastille without holding a trial or giving him an opportunity to defend himself. Fearing an indefinite prison sentence, Voltaire suggested his own exile to England as an alternative punishment, an idea the French authorities accepted. This incident marked the beginning of Voltaire's attempts to improve the French judicial system.

Voltaire's exile in Great Britain lasted nearly three years, and his experiences there greatly influenced many of his ideas. The young man was intrigued by Britain's constitutional monarchy in contrast to the French absolute monarchy, as well as the country's relative support of the freedoms of speech and religion. He was also influenced by several of the neoclassical writers of the age, and developed an interest in earlier English literature, especially the works of Shakespeare, still little known in continental Europe at the time. Despite pointing out his deviations from neoclassical standards, Voltaire saw Shakespeare as an example French writers might look up to, since drama in France, despite being more polished, lacked on-stage action. Later, however, as Shakespeare's influence was being increasingly felt in France, Voltaire would endeavour to set a contrary example with his own plays, decrying what he considered Shakespeare's barbarities.

After almost three years in exile, Voltaire returned to Paris and published his views on British attitudes towards government, literature, and religion in a collection of essays in letter form entitled the Lettres philosophiques sur les Anglais (Philosophical Letters on the English). Because he regarded the British constitutional monarchy as more developed and more respectful of human rights (particularly religious tolerance) than its French counterpart, these letters met great controversy in France, to the point where the book was burnt and Voltaire was forced again to flee.

Château de Cirey

Voltaire's next destination was the Château de Cirey, located on the borders of Champagne and Lorraine. The building was renovated with his money, and here he began a relationship with the Marquise du Châtelet, Gabrielle Émilie le Tonnelier de Breteuil (famous in her own right as Émilie du Châtelet). Cirey was owned by the Marquise's husband, Marquis Florent-Claude du Chatelet, who sometimes visited his wife and her lover at the chateau. The relationship, which lasted for fifteen years, had a significant intellectual element. Voltaire and the Marquise collected over 21,000 books, an enormous number for the time. Together, they studied these books and performed experiments in the "natural sciences" in his laboratory. Voltaire's experiments included an attempt to determine the elements of fire.

Having learned from his previous brushes with the authorities, Voltaire began his future habit of keeping out of personal harm's way, and denying any awkward responsibility. He continued to write many plays, such as Mérope (or "La Mérope française") and began his long researches into science and history . Again, a main source of inspiration for Voltaire were the years of his British exile, during which he had been strongly influenced by the works of Sir Isaac Newton. Voltaire strongly believed in Newton's theories, especially concerning optics (Newton’s discovery that white light is composed of all the colours in the spectrum led to many experiments at Cirey), and gravity (Voltaire is the source of the famous story of Newton and the apple falling from the tree, which he had learned from Newton's niece in London and first mentioned in his Essai sur la poésie épique, or Essay on Epic Poetry). Although both Voltaire and the Marquise were curious about the philosophies of Gottfried Leibniz, a contemporary and rival of Newton, they remained essentially "Newtonians", despite the Marquise's adoption of certain aspects of Leibniz's arguments against Newton. She translated Newton's Latin Principia in full, adjusting a few errors along the way, and hers remained the definitive French translation well into the 20th century. Voltaire's book Eléments de la philosophie de Newton (Elements of Newton's Philosophy), which was probably co-written with the Marquise, made Newton accessible to a far greater public. It is often considered the work that finally brought about general acceptance of Newton's optical and gravitational theories.

Voltaire and the Marquise also studied history...particularly those persons who had contributed to civilization. Voltaire's second essay in English had been Essay upon the Civil Wars in France. It was followed by La Henriade, an epic poem on the French king Henri IV, glorifying his attempt to end the Catholic-Protestant massacres with the Edict of Nantes, and by a historical novel on King Charles XII of Sweden. These, along with his Letters on England mark the beginning of Voltaire's open criticism of intolerance and established religions. Voltaire and the Marquise also worked with philosophy, particularly with metaphysics, the branch of philosophy that deals with being, and what is beyond the material realm such as whether or not there is a God or souls, etc. Voltaire and the Marquise analyzed the Bible, trying to discover its validity in their time. Voltaire's critical views on religion are reflected in his belief in separation of church and state and religious freedom, ideas that he had formed after his stay in England.

Though deeply committed to the Marquise, Voltaire by 1744 found life at the château confining. On a visit to Paris that year, he found a new love: his niece. At first, his attraction to Marie Louise Mignot was clearly sexual, as evidenced by his letters to her (only discovered in 1937). Much later, they lived together, perhaps platonically, and remained together until Voltaire's death. Meanwhile, the Marquise also took a lover, the Marquis de Saint-Lambert.

Sanssouci

After the death of the Marquise in childbirth in September 1749, Voltaire briefly returned to Paris and in 1750 moved to Potsdam to join Frederick the Great, a close friend and admirer of his. The king had repeatedly invited him to his palace, and now gave him a salary of 20,000 francs a year. Though life went well at first...in 1752 he wrote Micromégas, perhaps the first piece of science fiction involving ambassadors from another planet witnessing the follies of humankind...his relationship with Frederick the Great began to deteriorate and he encountered other difficulties. An argument with Maupertuis, the president of the Berlin Academy of Science, provoked Voltaire's Diatribe du docteur Akakia (Diatribe of Doctor Akakia), which satirized some of Maupertuis' theories and his abuse of power in his persecutions of a mutual acquaintance, Samuel Koënig. This greatly angered Frederick, who had all copies of the document burned and arrested Voltaire at an inn where he was staying along his journey home. Voltaire's chateau is now owned and administered by the French Ministry of Culture.

In the Scottish Enlightenment the Scots began developing a uniquely practical branch of humanism to the extent that Voltaire said "We look to Scotland for all our ideas of civilisation".

Once in a letter to Frederick II, King of Prussia, dated 5 January 1767 he quoted that,

Attitude toward Jews

Though many books have been written taxing Voltaire with anti-semitism, they do not explain, nor usually even mention, the numerous pamphlets he wrote attacking anti-semitism itself. This apparent contradiction led many to conclude that his remarks were in fact anti-Biblical and not anti-semitic. His "Sermon du rabbin Akib", for example, is a scathing attack on Christian persecution of the Jews, and similar remarks can be found scattered throughout his 200-odd pamphlets and books on religion.

It has been pointed out that thirty of the 118 articles in his Dictionnaire Philosophique described the ancient Jews in consistently negative ways, as barbarous, absurd and deeply superstitious; however, this ignores his qualifiers, in which he points out that "all of antiquity was", as a rule.

Peter Gay, the best known contemporary authority on the Enlightenment, wrote that "Voltaire struck at the Jews to strike at Christianity," a view shared by certain leading Jewish Voltairians...indeed, the point usually is, if the Jews were cruel and absurd, what can be made of other faiths that declare their histories sacred, yet persecute them? "When I see Christians cursing Jews," he wrote in his English Notebook, "methinks I see children beating their fathers." And posing as a freshly minted Spanish priest in Les Questions de Zapata, he asks his superiors how he should go about explaining that the Jews, whom they burn by the hundreds, were the chosen people of God for four thousand years, and why we chant their prayers while burning them. Voltaire grew exceedingly vocal against the Church during the campaign for tolerance of his later years, openly writing that it had been the "consistently implacable enemy of progress, decency, humanity and rationality" and that it had been the Church's interest to "keep people as ignorant and submissive as children".

Freemasonry

Voltaire was initiated into Freemasonry one month before his death. On April 4, 1778 Voltaire accompanied his close friend Benjamin Franklin into Loge des Neuf Soeurs in Paris, France and became an Entered Apprentice Freemason, perhaps only to please Franklin.

Voltaire perceived the French bourgeoisie to be too small and ineffective, the aristocracy to be parasitic and corrupt, the commoners as ignorant and superstitious, and the church as a static and oppressive force useful only as a counterbalance since its "religious tax" or the tithe helped to create a strong backing for revolutionaries.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, Candide, ou l'Optimisme (Candide, or Optimism, 1759), which ends with a new conclusion: "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 subject to censorship and Voltaire jokingly claimed the actual author was a certain "Demad" in a letter, where he reaffirmed the main polemical stances of the text.

Voltaire is also known for many memorable aphorisms, such as: "Si Dieu n'existait pas, il faudrait l'inventer" ("If God did not exist, it would be necessary to invent him"), contained in a verse epistle from 1768, addressed to the anonymous author of a controversial work, "The Three Impostors." But far from being the cynical remark it is often taken for, it was meant as a retort to the atheistic clique of d'Holbach, Grimm, and others.

Voltaire is remembered and honored in France as a courageous polemicist who indefatigably fought for civil rights...the right to a fair trial and freedom of religion...and who denounced the hypocrisies and injustices of the ancien régime. The ancien régime involved an unfair balance of power and taxes between the First Estate (the clergy), the Second Estate (the nobles), and the Third Estate (the commoners and middle class, who were burdened with most of the taxes).

Voltaire has had his detractors among his later colleagues. The Scottish Victorian writer Thomas Carlyle argued that, while Voltaire was unsurpassed in literary form, not even the most elaborate of his works were of much value for matter and that he never uttered an original idea of his own.

He often used China, Siam and Japan as examples of brilliant non-European civilizations and harshly criticized slavery,.

The town of Ferney, where Voltaire lived out the last 20 years of his life, is now named Ferney-Voltaire in honor of its most famous resident. His château is a museum.

Voltaire's library is preserved intact in the National Library of Russia at St. Petersburg, Russia.

In Zurich 1916, the theater and performance group who would become the early avant-garde movement Dada named their theater The Cabaret Voltaire. A late-20th-century industrial music group then named themselves after the theater.

A character based on Voltaire plays an important role in The Age of Unreason, a series of four alternative history novels written by American science fiction and fantasy author Gregory Keyes.

Voltaire was also known to have been an advocate for coffee, as he was purported to have drunk the beverage at least 30 times per day. It has been suggested that high amounts of caffeine acted as a mental stimulant to his creativity.

His great grand-niece was the mother of Pierre Teilhard de Chardin, a famous writer and Jesuit priest.
