Voltaire (François-Marie Arouet) (November 21, 1694 – May 30, 1778) was a prolific writer, philosopher, poet and pamphletist, and the preeminent figure of the eighteenth-century French Enlightenment.

An acerbic social critic, Voltaire condemned injustice, clerical abuses, prejudice, and fanaticism. He rejected formalized religion, which he saw as superstitious and irrational, although as a deist, he believed in a supreme being. Voltaire emphasized reason, despised democracy as the rule of the mob, and believed that an enlightened monarchy, informed by the counsels of the wise, was best suited to govern.

Though Voltaire used the weapon of his wit primarily against corrupt institutions, first and foremost the Church, his attacks also aimed at revealed religion itself. His often considerable cynicism in these matters should nevertheless be seen in the context of the abysmal condition of religious life in eighteenth-century France, particularly among the educated classes. The utilitariandeism promoted by Voltaire, with its emphasis on humanistic virtues, its rejection of dogma, and its ignorance of the inner life, was the almost inevitable response to the prevailing role of the church of his time. His rejection of church authority and conventional morality also enabled Voltaire to maintain a 16-year liaison with a 27-year-old married mother of three children.

Voltaire's and other French Enlightenment philosophes' emphasis on reason above feeling would provoke a reaction during the Romantic era in the arts and literature, as well as in religious expression, notably in such theologians as Friedrich Schleiermacher. Yet the humanistic thought of Voltaire would remain an important current in the nineteenth century. Karl Marx, Charles Darwin, Friedrich Nietzsche and other thinkers would promulgate blistering critiques of religion and advance materialist explanations of human origins, history, and the inner life that would form the basis of contentious philosophical, political, and social debate in the modern era.

Above anyone else, Voltaire has also come to embody what many consider to be the typically French qualities: wit and elegance of expression. At home and abroad, the French language is sometimes referred to as the “language of Voltaire,” and even the country is sometimes called the “country of Voltaire.”


Early years

François Marie Arouet, known as Voltaire, was born in Paris as the last child of a wealth notary, François Arouet, and Marie-Marguerite Daumart or D'Aumard. Voltaire's mother died when he was seven years old. At age nine, he was sent to the Jesuit Collège Louis-le-Grand, and remained there until 1711. Though he derided the education he had received, it formed the basis of his considerable knowledge, and probably kindled his lifelong devotion to theater. Voltaire maintained a lasting friendship with some Jesuit fathers.

When he graduated and returned home at the age of 17, Voltaire planned to start a career in writing, but his father opposed it. He studied law, at least nominally, and later pretended to work in a Parisian lawyer's office, but began writing libelous poems while getting involved with a high society known for its libertinism. As a result, in 1714 his father sent him to stay for nearly a year in The Hague.

Voltaire returned to Paris around the time of the death of Louis XIV. He was soon accused of composing a satire about the Regent and he was sent to the Bastille where he stayed for about a year from 1717 to 1718. There he completed his first play, Oedipe, which was also to be his first success, he began the Henriade and decided to change his name to Voltaire. The most commonly accepted hypothesis is that it is an anagram of the name "Arouet le jeune" or "Arouet l.j.," 'u' being changed to 'v' and 'j' to 'i' according to the ordinary convention.

Exile to England and return

In late 1725, Voltaire was involved in an argument with a nobleman, the Chevalier de Rohan. As a result, he was first sent again to the Bastille based on a secret warrant called a lettre de cachet. In 1726 he chose exile in England instead of imprisonment. The incident left an indelible impression on Voltaire, and from that day onward he became an advocate for judicial reform.

While in England Voltaire was attracted to the philosophy of John Locke and ideas of Sir Isaac Newton. He studied England's constitutional monarchy, its religious tolerance, its philosophical rationalism and the natural sciences. Voltaire also greatly admired English religious tolerance and freedom of speech, and saw these as necessary prerequisites for social and political progress. He saw England as a useful model for what he considered to be a backward France.

Upon his return to France in 1729 after three years of exile, he spread the substance of his discoveries in his Lettres philosophiques (Philosophical Letters). This work was considered an open attack on the Church and publicly burned. Voltaire himself was safe in the independent duchy of Lorraine where he had begun what was to be a long relationship with Émilie du Châtelet. The marquise du Châtelet was not only his lover but also his close literary and scientific collaborator.

In 1735, Voltaire was allowed to return to Paris, which at first he only did occasionally. While continuing a more and more successful career as a writer, he also reverted to the business of courtiership. A combination of both brought success (including a medal from the Pope) as well as trouble, since Voltaire was unable to lastingly control his taste for witty criticism. In 1746 Voltaire, who had been for years acknowledged the first writer in France, was at last elected to the Académie Française. In 1749, Madame du Châtelet died while giving birth to a child that was not Voltaire’s. This death, which deeply disturbed him, was another turning point in Voltaire's life.

In 1751, Voltaire accepted Frederick of Prussia's invitations and moved to Berlin where he stayed at the king’s court until 1753. Inevitably, the enlightened but authoritarian king was soon and repeatedly offended by his guest. Voltaire believed the king took advantage of him, and not allowed to return to Paris, Voltaire spent an unstable period before settling in Geneva’s “Les Délices.”

Geneva and Ferney

There, feeling safer, he set up a considerable establishment, which his great wealth made him able to easily afford. He kept open house for visitors; he had printers close at hand in Geneva; he fitted up a private theatre in which he could enjoy what was perhaps the greatest pleasure of his whole life—acting in a play of his own, stage-managed by himself.

His residence at Geneva brought him into correspondence (at first quite amicable) with the most famous of its citizens, Jean-Jacques Rousseau. The two men would soon come to hate each other intensely and publicly, Voltaire using his reputation to destroy that of his opponent. Calvinist Geneva’s prohibitions of theatrical performances finally caused Voltaire to abandon the city for nearby Ferney (now called Ferney-Voltaire).

At the end of 1758 he bought the considerable property there, about four miles from Geneva, and on French soil. At Ferney, he became a complete country gentleman, and was henceforward known to all Europe as Monsieur de Voltaire, the patriarch of Ferney. His entrepreneurial spirit allowed him to greatly develop the area and to employ more than one thousand people. In his comparatively secure position, he now engaged much more strongly in public controversies. He began a series of interferences on behalf of the oppressed that is an honor to his memory, the most famous being the “Calas affair” where he tried to save a man from unjustified judicial death.

A catastrophic earthquake in Lisbon gave Voltaire an opportunity to ridicule the fashionable optimism of the philosopher Gottfried Leibniz (“we live in the best possible world”) in the comic novella Candide (1759), One of the most widely read satires in the Western literature, the book was widely banned because of its scandalous political and religious criticisms and libertine adventures.

Return to Paris and death

Voltaire returned to a hero's welcome in Paris at age 83 in time to see his last play, Irene, produced. The excitement of the trip was too much for him and he died in Paris on May 30, 1778. Because of his criticism of the Church, Voltaire was denied burial in church ground. He was finally buried at an abbey in Champagne. In 1791 his remains were moved to a resting place at The Panthéon in Paris, where he lies alongside his nemesis Rousseau.

Voltaire and the Enlightenment

Voltaire was a philosopher in the sense of the French eighteenth-century philosophes, free thinkers in an age where freedom of thought was emerging sufficiently to stimulate challenges to the established order. The philosophes, including Voltaire, Montesquieu, d’Alembert and Diderot, were not philosophers in the technical sense of the word, neither were they academically trained scholars operating in the official institutions of their time. Through their background, many were fortunate enough to enjoy the best education available and their talent allowed them to make full use of it. Their philosophical writings are the forerunners of what today would be called ideology, i.e., the polemical use of ideas to promote a cause, often with little in-depth exploration. Such was the project of the Encyclopédie, to which Voltaire contributed numerous articles.

Voltaire is well known for his defense of civil liberties, including freedom of religion and the right to a fair trial. He was an outspoken supporter of social reform despite strict censorship laws in France and harsh penalties for those who broke them. A satirical polemist, he frequently made use of his works to criticize Church dogma and the French institutions of his day. His polemics against the Church could be quite devastating. Though his wit was sharper than any other, Voltaire was, however, far from being the most extreme among the philosophes in his promotion of the new “secular messianism.” He advocated neither atheism (as, for example, Diderot did) nor the overthrow of the regime. The name of Voltaire is synonymous with deism, the rational belief in a God as the great watchmaker and architect of the universe, utterly unrelated to revelation and the dogmas of the Church and Christianity.

Finally, Voltaire was typical of the Enlightenment in France in that he not only showed an anti-religious bias, but also displayed a strong tendency towards libertinism and hedonism. On these two points, disciples of the Enlightenment in Germany (Immanuel Kant) and in America (Thomas Jefferson) parted ways with Voltaire and his fellow philosophes.

Much of Voltaire’s production expresses the pure enjoyment of the intellectual play with words. Nevertheless, his writings had a considerable effect on the developments that led to the French Revolution shortly after his death. The impact of his ideas was multiplied by the considerable prestige he had gained in old age, a time when he had come to be almost universally admired and revered as a sage and living legend—in ways the young Voltaire would perhaps have scorned.

Voltaire’s philosophy and ideas

Voltaire was a man of ideas, not a lover of systems, be it for others or for himself. Both in content and in style, Voltaire’s philosophical attitudes were influenced by John Locke and England’s skepticalempiricism. He ridiculed both the religious optimism of Leibniz as well as the humanistic optimism of Rousseau. He greatly contributed to the lessening of Descartes’ influence in France and generally to the elimination of metaphysical concerns. Voltaire’s philosophical ideas and ethical and social criticism tended not to be original, but he generally displayed a keen common sense. The originality of his contribution to philosophy was his genius at translating and spreading others’ ideas and forming a front of irresistible power.

Voltaire believed in progress and in the virtues of civilization, contrary to Rousseau’s belief that civilization corrupts man. However, his faith in culture was measured and he did not expect the coming of any golden age.

Voltaire and religion

Throughout his life, Voltaire fought for religious liberty. He discovered its virtues early on in his life, during his stay in England. In his Philosophical Letters (Letter 6, “On the Church in England”), Voltaire said, “If there were only one religion in England there would be danger of despotism; if there were two they would cut each other’s throats. But there are thirty, and they live in peace and happiness.” Later, he would fight with a vengeance to right the wrongs perpetrated against Protestants, whose beliefs he was far from sharing. This passion came together with an equally strong dislike of the institutions of the Catholic Church and its abuses. In spite of an occasional positive interaction and mutual respect in isolated situations, Voltaire found himself in a lifelong battle against the Church. He was also distrustful of religious enthusiasm and the emphasis on human sin (Blaise Pascal), both of which in his eyes represented the danger of fanaticism.

Voltaire’s position towards religion per se oscillated between prudent approval and violent opposition, complete with incisive verbal abuse. Voltaire is known to have recommended that religion be maintained for the people as a deterrent and an encouragement toward the good life. He is famous for saying “Si Dieu n'existait pas, il faudrait l'inventer” (If God did not exist, it would be necessary to invent him). There was, however, more than mere cynicism in his position. Voltaire’s viewpoint is best summarized in the article entitled “theist” of his Philosophical Dictionary ("theist" stands for "deist" in Voltaire’s terminology). The theist, Voltaire states, is deeply convinced of the existence of a supreme being “as good as He is powerful,” just without cruelty and kind in his rewards. He makes no claim to any knowledge about this God, his motives and his ways, and rebukes those who do. The theist’s religion is that of a universal brotherhood, that of helping the needy and defending the oppressed.

Voltaire's works, and especially his private letters, constantly contain the word l'infâme and the expression écrasez l'infâme (crush the infamy). This expression clearly refers to religious abuse and oppression, not to Christ or the Church. However, Voltaire’s opinion about revealed religion, Christianity in particular, was negative. For him, dogma and specific beliefs were an obstacle, rather than an aid. He considered the Jewish people to be a small desert nation without a culture that had unduly undermined the achievements of much greater civilizations. He was equally unkind to the content of the Gospels.

Voltaire as a businessman

In spite of his aristocratic pretension, Voltaire was a son of the bourgeoisie and he embodied that class’s spirit of entrepreneurship. His stays in England, Holland, and later Geneva certainly contributed to love for free enterprise. He had always had a keen sense for business and became wealthy early on, in ways that were not always to be recommended. Towards the end of his life, in Ferney, he had become a large-scale industrialist. He had actually created a sizeable community around his own estates, thus accomplishing what future social utopists would often try in vain to achieve.

These accomplishments fit well with Voltaire’s agnosticism and muted pessimism in religious matters. His famous Candide concludes with the statement that one has to “cultivate one’s garden” instead of pursuing impossible metaphysical dreams. In Ferney, Voltaire had the opportunity to do just that, quite literally.


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 force only useful as a counterbalance since its "religious tax," or the tithe, helped to cement a powerbase against the monarchy.

Voltaire distrusted democracy, which he saw as propagating the "idiocy of the masses". To Voltaire only an enlightened monarch, advised by philosophers like himself, could bring about change as it was in the king's rational interest to improve the power and wealth of France in the world. Voltaire is quoted as saying that he “would rather obey one lion, than two hundred rats of [his own] species.” Voltaire essentially believed monarchy to be the key to progress and change.

Almost all his more substantive works, whether in verse or prose, are preceded by prefaces of one sort or another, which are models of his own light pungent causerie; and in a vast variety of nondescript pamphlets and writings he shows himself a perfect journalist.


Voltaire was a prolific writer and produced works in almost every literary form, authoring plays, poetry, novels, essays, historical, philosophical and scientific works, pamphlets, and over 20,000 letters. Voltaire made significant contributions to social studies and history with works like The Century of Louis XIV,Charles XII (1731), which rejected the proposition of a divine providence in history, and the “Essay sur les Moeurs.” His Philosophical Letters (1734), written after his return to France after some years in England, compared the French and English systems of government, to the discredit of his native France. His satirical and subversive Philosophical Dictionary (1764) argued that the religion should teach little dogma but much morality.

In his time, Voltaire became famous for what later generations would consider to be the wrong reasons: his tragedies and epic poems. These productions, admired by Voltaire’s contemporaries, are now considered technically well done but conventional and devoid of creativity. They hint to one of Voltaire’s lesser traits of character, his vain desire for admiration, while the real Voltaire spontaneously appears in the less formal setting of his “contes” (tales) and letters.

Voltaire's tales are unquestionably the most remarkable fruit of his genius. They were usually composed as pamphlets, with a purpose of polemic in religion, politics, and “idées reçues” (idea that are generally and uncritically accepted). In works such as Candide,L'Homme aux quarante écus,Zadig and others that puncture received forms of moral and metaphysical orthodoxy, the peculiar quality of Voltaire—ironic style without exaggeration—appears.

Candide is the most widely read of Voltaire's many works and his only work which has remained popular up to the present day. The novella begins with a young man, Candide, who is living a sheltered life and being indoctrinated with Leibnizianoptimism by his tutor, Pangloss. The work describes Candide's slow, painful disillusionment as he witnesses and experiences great hardships in the world.

Candide is known for its sarcastic tone and its erratic, fantastical, and fast-moving plot. With a story similar to that of a more serious bildungsroman or picaresque novel, it parodies many adventure and romance clichés. Voltaire ridicules religion, theologians, governments, armies, philosophies, and philosophers, most conspicuously Leibniz and his optimism.

As expected by Voltaire, Candide enjoyed both great success and great scandal. Immediately after its secretive publication, the book was widely banned because it contained religious blasphemy and political sedition hidden under a thin veil of naïveté. Today, Candide is recognized as Voltaire's magnum opus and included as part of the Western canon.

Voltaire’s vast correspondence is constantly being augmented by fresh discoveries, much of it remaining unpublished. In this collection of letters, Voltaire's personality is best shown. His immense energy and versatility, his adroit and unhesitating flattery when he chose to flatter, his ruthless sarcasm when he chose to be sarcastic, his rather unscrupulous business faculty, his determination to anything necessary to escape his enemies—all these things appear throughout the whole mass of letters. Voltaire’s lasting friendship with a few individuals also appears through his informal exchange with them, much of which is filled with spicy remarks.


Voltaire's legacy has been immense. Voltaire envisioned a secular, tolerant society and emphasized progress through scientific advances and social and political reform, and through transcending the confines of religious dogma and superstition. The influence of these Enlightenment ideals would survive the reaction of the Romantic era and, following the Industrial Revolution, emerge in the twentieth century in a renewed rationalist challenge to the truth claims of revealed religion.

Voltaire's emphasis on reason and justice, his icy wit, and his formidable gifts as a satirist and polemicist influenced such Enlightenment figures as Benjamin Franklin and Thomas Jefferson. His affirmation of civil rights and the principle of religious freedom would find expression in the U.S. Constitution and its guarantees of freedoms of speech, the press, and religion.

In France, Voltaire's fiery condemnation of the corruption of the church bore fruit in the radicalism and violence of the French Revolution in 1789. Anti-clerical violence and appropriation of church lands would undermine the church and the role of religion in French life. Voltaire has cast a shadow over much of Europe to the present day in the marginalizing of Christianity and secularism of European society.

Not surprisingly for a man renowned for his bons mots, a great number of quotes circulate that are attributed to Voltaire. These include:

  • "This agglomeration which was called and which still calls itself the Holy Roman Empire was neither holy, nor Roman, nor an empire."
  • "God is a comedian playing to an audience too afraid to laugh."
  • "I shall finally have to renounce your Optimism? I'm afraid to say that it's a mania for insisting that all is well when things are going badly." (Candide, renouncing the Leibnizian Optimism)
  • Jean-Baptiste Rousseau, not to be confused with the philosopher Jean-Jacques Rousseau, sent a copy of his "Ode to Posterity" to Voltaire. Voltaire read it through and said, "I do not think this poem will reach its destination."
  • "One hundred years from my day there will not be a Bible in the earth except one that is looked upon by an antiquarian curiosity seeker." (1776)
  • "Think for yourselves and let others enjoy the privilege to do so too." (Essay on Tolerance)
  • "Le mieux est l'ennemi du bien." Translation: "The best is the enemy of the good." (Dictionnaire Philosophique).
  • "If God did not exist, it would be necessary to invent him." (Epistle on the "Three Imposters"). This statement by Voltaire became so familiar that Gustave Flaubert included it in his Dictionnaire des idées reçues ("Dictionary of commonplace ideas"), and it is still among the most frequently quoted of Voltaire's dicta [1].


The following quote is commonly misattributed to Voltaire:

I do not agree with a word you say but will defend to the death your right to say it.

It was actually first used by Evelyn Beatrice Hall, writing under the pseudonym of Stephen G. Tallentyre in The Friends of Voltaire (1906), as a summation of Voltaire's attitude, based on statements in Essay on Tolerance where he asserts: "Think for yourselves and let others enjoy the privilege to do so too."

1. Voltaire's Life: The Philosopher as Critic and Public Activist

Voltaire only began to identify himself with philosophy and the philosophe identity during middle age. His work Lettres philosophiques, published in 1734 when he was forty years old, was the key turning point in this transformation. Before this date, Voltaire's life in no way pointed him toward the philosophical destiny that he was later to assume. His early orientation toward literature and libertine sociability, however, shaped his philosophical identity in crucial ways.

1.1 Voltaire's Early Years (1694–1726)

François-Marie d'Arouet was born in 1694, the fourth of five children, to a well-to-do public official and his well bred aristocratic wife. In its fusion of traditional French aristocratic pedigree with the new wealth and power of royal bureaucratic administration, the d'Arouet family was representative of elite society in France during the reign of Louis XIV. The young François-Marie acquired from his parents the benefits of prosperity and political favor, and from the Jesuits at the prestigious Collège Louis-le-Grand in Paris he also acquired a first-class education. François-Marie also acquired an introduction to modern letters from his father who was active in the literary culture of the period both in Paris and at the royal court of Versailles. François senior appears to have enjoyed the company of men of letters, yet his frustration with his son's ambition to become a writer is notorious. From early in his youth, Voltaire aspired to emulate his idols Molière, Racine, and Corneille and become a playwright, yet Voltaire's father strenuously opposed the idea, hoping to install his son instead in a position of public authority. First as a law student, then as a lawyer's apprentice, and finally as a secretary to a French diplomat, Voltaire attempted to fulfill his father's wishes. But in each case, he ended up abandoning his posts, sometimes amidst scandal.

Escaping from the burdens of these public obligations, Voltaire would retreat into the libertine sociability of Paris. It was here in the 1720s, during the culturally vibrant period of the Regency government between the reigns of Louis XIV and XV (1715–1723), that Voltaire established one dimension of his identity. His wit and congeniality were legendary even as a youth, so he had few difficulties establishing himself as a popular figure in Regency literary circles. He also learned how to play the patronage game so important to those with writerly ambitions. Thanks, therefore, to some artfully composed writings, a couple of well-made contacts, more than a few bon mots, and a little successful investing, especially during John Law's Mississippi Bubble fiasco, Voltaire was able to establish himself as an independent man of letters in Paris. His literary debut occurred in 1718 with the publication of his Oedipe, a reworking of the ancient tragedy that evoked the French classicism of Racine and Corneille. The play was first performed at the home of the Duchesse du Maine at Sceaux, a sign of Voltaire's quick ascent to the very pinnacle of elite literary society. Its published title page also announced the new pen name that Voltaire would ever after deploy.

During the Regency, Voltaire circulated widely in elite circles such as those that congregated at Sceaux, but he also cultivated more illicit and libertine sociability as well. This pairing was not at all uncommon during this time, and Voltaire's intellectual work in the 1720s—a mix of poems and plays that shifted between playful libertinism and serious classicism seemingly without pause—illustrated perfectly the values of pleasure, honnêteté, and good taste that were the watchwords of this cultural milieu. Philosophy was also a part of this mix, and during the Regency the young Voltaire was especially shaped by his contacts with the English aristocrat, freethinker,and Jacobite Lord Bolingbroke. Bolingbroke lived in exile in France during the Regency period, and Voltaire was a frequent visitor to La Source, the Englishman's estate near Orléans. The chateau served as a reunion point for a wide range of intellectuals, and many believe that Voltaire was first introduced to natural philosophy generally, and to the work of Locke and the English Newtonians specifically, at Bolingbroke's estate. It was certainly true that these ideas, especially in their more deistic and libertine configurations, were at the heart of Bolingbroke's identity.

1.2 The English Period (1726–1729)

Yet even if Voltaire was introduced to English philosophy in this way, its influence on his thought was most shaped by his brief exile in England between 1726–29. The occasion for his departure was an affair of honor. A very powerful aristocrat, the Duc de Rohan, accused Voltaire of defamation, and in the face of this charge the untitled writer chose to save face and avoid more serious prosecution by leaving the country indefinitely. In the spring of 1726, therefore, Voltaire left Paris for England.

It was during his English period that Voltaire's transition into his mature philosophe identity began. Bolingbroke, whose address Voltaire left in Paris as his own forwarding address, was one conduit of influence. In particular, Voltaire met through Bolingbroke Jonathan Swift, Alexander Pope, and John Gay, writers who were at that moment beginning to experiment with the use of literary forms such as the novel and theater in the creation of a new kind of critical public politics. Swift's Gulliver's Travels, which appeared only months before Voltaire's arrival, is the most famous exemplar of this new fusion of writing with political criticism. Later the same year Bolingbroke also brought out the first issue of the Craftsman, a political journal that served as the public platform for his circle's Tory opposition to the Whig oligarchy in England. The Craftsman helped to create English political journalism in the grand style, and for the next three years Voltaire moved in Bolingbroke's circle, absorbing the culture and sharing in the public political contestation that was percolating all around him.

Voltaire did not restrict himself to Bolingbroke's circle alone, however. After Bolingbroke, his primary contact in England was a merchant by the name of Everard Fawkener. Fawkener introduced Voltaire to a side of London life entirely different from that offered by Bolingbroke's circle of Tory intellectuals. This included the Whig circles that Bolingbroke's group opposed. It also included figures such as Samuel Clarke and other self-proclaimed Newtonians. Voltaire did not meet Newton himself before Sir Isaac's death in March, 1727, but he did meet his sister—learning from her the famous myth of Newton's apple, which Voltaire would play a major role in making famous. Voltaire also came to know the other Newtonians in Clarke's circle, and since he became proficient enough with English to write letters and even fiction in the language, it is very likely that he immersed himself in their writings as well. Voltaire also visited Holland during these years, forming important contacts with Dutch journalists and publishers and meeting Willem 'sGravesande and other Dutch Newtonian savants. Given his other activities, it is also likely that Voltaire frequented the coffeehouses of London even if no firm evidence survives confirming that he did. It would not be surprising, therefore, to learn that Voltaire attended the Newtonian public lectures of John Theophilus Desaguliers or those of one of his rivals. Whatever the precise conduits, all of his encounters in England made Voltaire into a very knowledgeable student of English natural philosophy.

1.3 Becoming a Philosophe

When French officials granted Voltaire permission to re-enter Paris in 1729, he was devoid of pensions and banned from the royal court at Versailles. But he was also a different kind of writer and thinker. It is no doubt overly grandiose to say with Lord Morley that, “Voltaire left France a poet and returned to it a sage.” It is also an exaggeration to say that he was transformed from a poet into a philosophe while in England. For one, these two sides of Voltaire's intellectual identity were forever intertwined, and he never experienced an absolute transformation from one into the other at any point in his life. But the English years did trigger a transformation in him.

After his return to France, Voltaire worked hard to restore his sources of financial and political support. The financial problems were the easiest to solve. In 1729, the French government staged a sort of lottery to help amortize some of the royal debt. A friend perceived an opportunity for investors in the structure of the government's offering, and at a dinner attended by Voltaire he formed a society to purchase shares. Voltaire participated, and in the fall of that year when the returns were posted he had made a fortune. Voltaire's inheritance from his father also became available to him at the same time, and from this date forward Voltaire never again struggled financially. This result was no insignificant development since Voltaire's financial independence effectively freed him from one dimension of the patronage system so necessary to aspiring writers and intellectuals in the period. In particular, while other writers were required to appeal to powerful financial patrons in order to secure the livelihood that made possible their intellectual careers, Voltaire was never again beholden to these imperatives.

The patronage structures of Old Regime France provided more than economic support to writers, however, and restoring the crédit upon which his reputation as a writer and thinker depended was far less simple. Gradually, however, through a combination of artfully written plays, poems, and essays and careful self-presentation in Parisian society, Voltaire began to regain his public stature. In the fall of 1732, when the next stage in his career began to unfold, Voltaire was residing at the royal court of Versailles, a sign that his re-establishment in French society was all but complete.

During this rehabilitation, Voltaire also formed a new relationship that was to prove profoundly influential in the subsequent decades. He became reacquainted with Emilie Le Tonnier de Breteuil,the daughter of one of his earliest patrons, who married in 1722 to become the Marquise du Châtelet. Emilie du Châtelet was twenty-nine years old in the spring of 1733 when Voltaire began his relationship with her. She was also a uniquely accomplished woman. Du Châtelet's father, the Baron de Breteuil, hosted a regular gathering of men of letters that included Voltaire, and his daughter, ten years younger than Voltaire, shared in these associations. Her father also ensured that Emilie received an education that was exceptional for girls at the time. She studied Greek and Latin and trained in mathematics, and when Voltaire reconnected with her in 1733 she was a very knowledgeable thinker in her own right even if her own intellectual career, which would include an original treatise in natural philosophy and a complete French translation of Newton's Principia Mathematica—still the only complete French translation ever published—had not yet begun. Her intellectual talents combined with her vivacious personality drew Voltaire to her, and although Du Châtelet was a titled aristocrat married to an important military officer, the couple was able to form a lasting partnership that did not interfere with Du Châtelet's marriage. This arrangement proved especially beneficial to Voltaire when scandal forced him to flee Paris and to establish himself permanently at the Du Châtelet family estate at Cirey. From 1734, when this arrangement began, to 1749, when Du Châtelet died during childbirth, Cirey was the home to each along with the site of an intense intellectual collaboration. It was during this period that both Voltaire and Du Châtelet became widely known philosophical figures, and the intellectual history of each before 1749 is most accurately described as the history of the couple's joint intellectual endeavors.

1.4 The Newton Wars (1732–1745)

For Voltaire, the events that sent him fleeing to Cirey were also the impetus for much of his work while there. While in England, Voltaire had begun to compose a set of letters framed according to the well-established genre of a traveler reporting to friends back home about foreign lands. Montesquieu's 1721 Lettres Persanes, which offered a set of fictionalized letters by Persians allegedly traveling in France, and Swift's 1726 Gulliver's Travels were clear influences when Voltaire conceived his work. But unlike the authors of these overtly fictionalized accounts, Voltaire innovated by adopting a journalistic stance instead, one that offered readers an empirically recognizable account of several aspects of English society. Originally titled Letters on England, Voltaire left a draft of the text with a London publisher before returning home in 1729. Once in France, he began to expand the work, adding to the letters drafted while in England, which focused largely on the different religious sects of England and the English Parliament, several new letters including some on English philosophy. The new text, which included letters on Bacon, Locke, Newton and the details of Newtonian natural philosophy along with an account of the English practice of inoculation for smallpox, also acquired a new title when it was first published in France in 1734: Lettres philosophiques.

Before it appeared, Voltaire attempted to get official permission for the book from the royal censors, a requirement in France at the time. His publisher, however, ultimately released the book without these approvals and without Voltaire's permission. This made the first edition of the Lettres philosophiques illicit, a fact that contributed to the scandal that it triggered, but one that in no way explains the furor the book caused. Historians in fact still scratch their heads when trying to understand why Voltaire's Lettres philosophiques proved to be so controversial. The only thing that is clear is that the work did cause a sensation that subsequently triggered a rapid and overwhelming response on the part of the French authorities. The book was publicly burned by the royal hangman several months after its release, and this act turned Voltaire into a widely known intellectual outlaw. Had it been executed, a royal lettre de cachet would have sent Voltaire to the royal prison of the Bastille as a result of his authorship of Lettres philosophiques; instead, he was able to flee with Du Châtelet to Cirey where the couple used the sovereignty granted by her aristocratic title to create a safe haven and base for Voltaire's new position as a philosophical rebel and writer in exile.

Had Voltaire been able to avoid the scandal triggered by the Lettres philosophiques, it is highly likely that he would have chosen to do so. Yet once it was thrust upon him, he adopted the identity of the philosophical exile and outlaw writer with conviction, using it to create a new identity for himself, one that was to have far reaching consequences for the history of Western philosophy. At first, Newtonian science served as the vehicle for this transformation. In the decades before 1734, a series of controversies had erupted, especially in France, about the character and legitimacy of Newtonian science, especially the theory of universal gravitation and the physics of gravitational attraction through empty space. Voltaire positioned his Lettres philosophiques as an intervention into these controversies, drafting a famous and widely cited letter that used an opposition between Newton and Descartes to frame a set of fundamental differences between English and French philosophy at the time. He also included other letters about Newtonian science in the work while linking (or so he claimed) the philosophies of Bacon, Locke, and Newton into an English philosophical complex that he championed as a remedy for the perceived errors and illusions perpetuated on the French by René Descartes and Nicolas Malebranche. Voltaire did not invent this framework, but he did use it to enflame a set of debates that were then raging, debates that placed him and a small group of young members of the Royal Academy of Sciences in Paris into apparent opposition to the older and more established members of this bastion of official French science. Once installed at Cirey, both Voltaire and Du Châtelet further exploited this apparent division by engaging in a campaign on behalf of Newtonianism, one that continually targeted an imagined monolith called French Academic Cartesianism as the enemy against which they in the name of Newtonianism were fighting.

The centerpiece of this campaign was Voltaire's Éléments de la Philosophie de Newton, which was first published in 1738 and then again in 1745 in a new and definitive edition that included a new section, first published in 1740, devoted to Newton's metaphysics. Voltaire offered this book as a clear, accurate, and accessible account of Newton's philosophy suitable for ignorant Frenchman (a group that he imagined to be large). But he also conceived of it as a machine de guerre directed against the Cartesian establishment, which he believed was holding France back from the modern light of scientific truth. Vociferous criticism of Voltaire and his work quickly erupted, with some critics emphasizing his rebellious and immoral proclivities while others focused on his precise scientific views. Voltaire collapsed both challenges into a singular vision of his enemy as “backward Cartesianism”. As he fought fiercely to defend his positions, an unprecedented culture war erupted in France centered on the character and value of Newtonian natural philosophy. Du Châtelet contributed to this campaign by writing a celebratory review of Voltaire's Éléments in the Journal des savants, the most authoritative French learned periodical of the day. The couple also added to their scientific credibility by receiving separate honorable mentions in the 1738 Paris Academy prize contest on the nature of fire. Voltaire likewise worked tirelessly rebutting critics and advancing his positions in pamphlets and contributions to learned periodicals. By 1745, when the definitive edition of Voltaire's Éléments was published, the tides of thought were turning his way, and by 1750 the perception had become widespread that France had been converted from backward, erroneous Cartesianism to modern, Enlightened Newtonianism thanks to the heroic intellectual efforts of figures like Voltaire.

1.5 From French Newtonian to Enlightenment Philosophe (1745–1755)

This apparent victory in the Newton Wars of the 1730s and 1740s allowed Voltaire's new philosophical identity to solidify. Especially crucial was the way that it allowed Voltaire's outlaw status, which he had never fully repudiated, to be rehabilitated in the public mind as a necessary and heroic defense of philosophical truth against the enemies of error and prejudice. From this perspective, Voltaire's critical stance could be reintegrated into traditional Old Regime society as a new kind of legitimate intellectual martyrdom. Since Voltaire also coupled his explicitly philosophical writings and polemics during the 1730s and 1740s with an equally extensive stream of plays, poems, stories, and narrative histories, many of which were orthogonal in both tone and content to the explicit campaigns of the Newton Wars, Voltaire was further able to reestablish his old identity as an Old Regime man of letters despite the scandals of these years. In 1745, Voltaire was named the Royal Historiographer of France, a title bestowed upon him as a result of his histories of Louis XIV and the Swedish King Charles II. This royal office also triggered the writing of arguably Voltaire's most widely read and influential book, at least in the eighteenth century, Essais sur les moeurs et l'esprit des nations (1751), a pioneering work of universal history. The position also legitimated him as an officially sanctioned savant. In 1749, after the death of du Châtelet, Voltaire reinforced this impression by accepting an invitation to join the court of the young Frederick the Great in Prussia, a move that further assimilated him into the power structures of Old Regime society.

Had this assimilationist trajectory continued during the remainder of Voltaire's life, his legacy in the history of Western philosophy might not have been so great. Yet during the 1750s, a set of new developments pulled Voltaire back toward his more radical and controversial identity and allowed him to rekindle the critical philosophe persona that he had innovated during the Newton Wars. The first step in this direction involved a dispute with his onetime colleague and ally, Pierre-Louis Moreau de Maupertuis. Maupertuis had preceded Voltaire as the first aggressive advocate for Newtonian science in France. When Voltaire was preparing his own Newtonian intervention in the Lettres philosophiques in 1732, he consulted with Maupertuis, who was by this date a pensioner in the French Royal Academy of Sciences. It was largely around Maupertuis that the young cohort of French academic Newtonians gathered during the Newton wars of 1730s and 40s, and with Voltaire fighting his own public campaigns on behalf of this same cause during the same period, the two men became the most visible faces of French Newtonianism even if they never really worked as a team in this effort. Like Voltaire, Maupertuis also shared a relationship with Emilie du Châtelet, one that included mathematical collaborations that far exceeded Voltaire's capacities. Maupertuis was also an occasional guest at Cirey, and a correspondent with both du Châtelet and Voltaire throughout these years. But in 1745 Maupertuis surprised all of French society by moving to Berlin to accept the directorship of Frederick the Great's newly reformed Berlin Academy of Sciences.

Maupertuis's thought at the time of his departure for Prussia was turning toward the metaphysics and rationalist epistemology of Leibniz as a solution to certain questions in natural philosophy. Du Châtelet also shared this tendency, producing in 1740 her Institutions de physiques, a systematic attempt to wed Newtonian mechanics with Leibnizian rationalism and metaphysics. Voltaire found this Leibnizian turn dyspeptic, and he began to craft an anti-Leibnizian discourse in the 1740s that became a bulwark of his brand of Newtonianism. This placed him in opposition to Du Châtelet, even if this intellectual rift in no way soured their relationship. Yet after she died in 1749, and Voltaire joined Maupertuis at Frederick the Great's court in Berlin, this anti-Leibnizianism became the centerpiece of a rift with Maupertuis. Voltaire's public satire of the President of the Royal Academy of Sciences of Berlin published in late 1752, which presented Maupertuis as a despotic philosophical buffoon, forced Frederick to make a choice. He sided with Maupertuis, ordering Voltaire to either retract his libelous text or leave Berlin. Voltaire chose the latter, falling once again into the role of scandalous rebel and exile as a result of his writings.

1.6 Fighting for Philosophie (1755–1778)

This event proved to be Voltaire's last official rupture with establishment authority. Rather than returning home to Paris and restoring his reputation, Voltaire instead settled in Geneva. When this austere Calvinist enclave proved completely unwelcoming, he took further steps toward independence by using his personal fortune to buy a chateau of his own in the hinterlands between France and Switzerland. Voltaire installed himself permanently at Ferney in early 1759, and from this date until his death in 1778 he made the chateau his permanent home and capital, at least in the minds of his intellectual allies, of the emerging French Enlightenment.

During this period, Voltaire also adopted what would become his most famous and influential intellectual stance, announcing himself as a member of the “party of humanity” and devoting himself toward waging war against the twin hydras of fanaticism and superstition. While the singular defense of Newtonian science had focused Voltaire's polemical energies in the 1730s and 1740s, after 1750 the program became the defense of philosophie tout court and the defeat of its perceived enemies within the ecclesiastical and aristo-monarchical establishment. In this way, Enlightenment philosophie became associated through Voltaire with the cultural and political program encapsulated in his famous motto, “Écrasez l'infâme!” (“Crush the infamy!”). This entanglement of philosophy with social criticism and reformist political action, a contingent historical outcome of Voltaire's particular intellectual career, would become his most lasting contribution to the history of philosophy.

The first cause to galvanize this new program was Diderot and d'Alembert's Encyclopédie. The first volume of this compendium of definitions appeared in 1751, and almost instantly the work became buried in the kind of scandal to which Voltaire had grown accustomed. Voltaire saw in the controversy a new call to action, and he joined forces with the project soon after its appearance, penning numerous articles that began to appear with volume 5 in 1755. Scandal continued to chase the Encyclopédie, however, and in 1759 the work's publication privilege was revoked in France, an act that did not kill the project but forced it into illicit production in Switzerland. During these scandals, Voltaire fought vigorously alongside the project's editors to defend the work, fusing the Encyclopédie's enemies, particularly the Parisian Jesuits who edited the monthly periodical the Journal de Trevoux, into a monolithic “infamy” devoted to eradicating truth and light from the world. This framing was recapitulated by the opponents of the Encyclopédie, who began to speak of the loose assemblage of authors who contributed articles to the work as a subversive coterie of philosophes devoted to undermining legitimate social and moral order.

As this polemic crystallized and grew in both energy and influence, Voltaire embraced its terms and made them his cause. He formed particularly close ties with d'Alembert, and with him began to generalize a broad program for Enlightenment centered on rallying the newly self-conscious philosophes (a term often used synonymously with the Encyclopédistes) toward political and intellectual change. In this program, the philosophes were not unified by any shared philosophy but through a commitment to the program of defending philosophie itself against its perceived enemies. They were also imagined as activists fighting to eradicate error and superstition from the world. The ongoing defense of the Encyclopédie was one rallying point, and soon the removal of the Jesuits—the great enemies of Enlightenment, the philosophes proclaimed—became a second unifying cause. This effort achieved victory in 1763, and soon the philosophes were attempting to infiltrate the academies and other institutions of knowledge in France. One climax in this effort was reached in 1774 when the Encyclopédiste and friend of Voltaire and the philosophes, Anne-Robert Jacques Turgot, was named Controller-General of France, the most powerful ministerial position in the kingdom, by the newly crowned King Louis XVI. Voltaire and his allies had paved the way for this victory through a barrage of writings throughout the 1760s and 1770s that presented philosophie like that espoused by Turgot as an agent of enlightened reform and its critics as prejudicial defenders of an ossified tradition.

Voltaire did bring out one explicitly philosophical book in support this campaign, his Dictionnaire philosophique of 1764–1770. This book republished his articles from the original Encyclopédie while adding new entries conceived in the spirit of the original work. Yet to fully understand the brand of philosophie that Voltaire made foundational to the Enlightenment, one needs to recognize that it just as often circulated in fictional stories, satires, poems, pamphlets, and other less obviously philosophical genres. Voltaire's most widely known text, for instance, Candide, ou l'Optimisme, first published in 1759, is a fictional story of a wandering traveler engaged in a set of farcical adventures. Yet contained in the text is a serious attack on Leibnizian philosophy, one that in many ways marks the culmination of Voltaire's decades long attack on this philosophy started during the Newton wars. Philosophie à la Voltaire also came in the form of political activism, such as his public defense of Jean Calas who, Voltaire argued, was a victim of a despotic state and an irrational and brutal judicial system. Voltaire often attached philosophical reflection to this political advocacy, such as when he facilitated a French translation of Cesare Beccaria's treatise on humanitarian justice and penal reform and then prefaced the work with his own essay on justice and religious toleration (Calas was a French protestant persecuted by a Catholic monarchy). Public philosophic campaigns such as these that channeled critical reason in a direct, oppositionalist way against the perceived injustices and absurdities of Old Regime life were the hallmark of philosophie as Voltaire understood the term.

1.7 Voltaire, Philosophe Icon of Enlightenment Philosophie (1778–Present)

Voltaire lived long enough to see some of his long-term legacies start to concretize. With the ascension of Louis XVI in 1774 and the appointment of Turgot as Controller-General, the French establishment began to embrace the philosophes and their agenda in a new way. Critics of Voltaire and his program for philosophie remained powerful, however, and they would continue to survive as the necessary backdrop to the positive image of the Enlightenment philosophe as a modernizer, progressive reformer, and courageous scourge against traditional authority that Voltaire bequeathed to later generations. During Voltaire's lifetime, this new acceptance translated into a final return to Paris in early 1778. Here, as a frail and sickly octogenarian, Voltaire was welcomed by the city as the hero of the Enlightenment that he now personified. A statue was commissioned as a permanent shrine to his legacy, and a public performance of his play Irène was performed in a way that allowed its author to be celebrated as a national hero. Voltaire died several weeks after these events, but the canonization that they initiated has continued right up until the present.

Western philosophy was profoundly shaped by the conception of the philosophe and the program for Enlightenment philosophie that Voltaire came to personify. The model he offered of the philosophe as critical public citizen and advocate first and foremost, and as abstruse and systematic thinker only when absolutely necessary, was especially influential in the subsequent development of the European philosophy. Also influential was the example he offered of the philosopher measuring the value of any philosophy according by its ability to effect social change. In this respect, Karl Marx's famous thesis that philosophy should aspire to change the world, not merely interpret it, owes more than a little debt Voltaire. The link between Voltaire and Marx was also established through the French revolutionary tradition, which similarly adopted Voltaire as one of its founding heroes. Voltaire was the first person to be honored with re-burial in the newly created Pantheon of the Great Men of France that the new revolutionary government created in 1791. This act served as a tribute to the connections that the revolutionaries saw between Voltaire's philosophical program and the cause of revolutionary modernization as a whole. In a similar way, Voltaire remains today an iconic hero for everyone who sees a positive linkage between critical reason and political resistance in projects of progressive, modernizing reform.

2. Voltaire's Enlightenment Philosophy

Voltaire's philosophical legacy ultimately resides as much in how he practiced philosophy, and in the ends toward which he directed his philosophical activity, as in any specific doctrine or original idea. Yet the particular philosophical positions he took, and the way that he used his wider philosophical campaigns to champion certain understandings while disparaging others, did create a constellation appropriately called Voltaire's Enlightenment philosophy. True to Voltaire's character, this constellation is best described as a set of intellectual stances and orientations rather than as a set of doctrines or systematically defended positions. Nevertheless, others found in Voltaire both a model of the well-oriented philosophe and a set of particular philosophical positions appropriate to this stance. Each side of this equation played a key role in defining the Enlightenment philosophie that Voltaire came to personify.

2.1 Liberty

Central to this complex is Voltaire's conception of liberty. Around this category, Voltaire's social activism and his relatively rare excursions into systematic philosophy also converged. In 1734, in the wake of the scandals triggered by the Lettres philosophiques, Voltaire wrote, but left unfinished at Cirey, a Traité de metaphysique that explored the question of human freedom in philosophical terms. The question was particularly central to European philosophical discussions at the time, and Voltaire's work explicitly referenced thinkers like Hobbes and Leibniz while wrestling with the questions of materialism, determinism, and providential purpose that were then central to the writings of the so-called deists, figures such as John Toland and Anthony Collins. The great debate between Samuel Clarke and Leibniz over the principles of Newtonian natural philosophy was also influential as Voltaire struggled to understand the nature of human existence and ethics within a cosmos governed by rational principles and impersonal laws.

Voltaire adopted a stance in this text somewhere between the strict determinism of rationalist materialists and the transcendent spiritualism and voluntarism of contemporary Christian natural theologians. For Voltaire, humans are not deterministic machines of matter and motion, and free will thus exists. But humans are also natural beings governed by inexorable natural laws, and his ethics anchored right action in a self that possessed the natural light of reason immanently. This stance distanced him from more radical deists like Toland, and he reinforced this position by also adopting an elitist understanding of the role of religion in society. For Voltaire, those equipped to understand their own reason could find the proper course of free action themselves. But since many were incapable of such self-knowledge and self-control, religion, he claimed, was a necessary guarantor of social order. This stance distanced Voltaire from the republican politics of Toland and other materialists, and Voltaire echoed these ideas in his political musings, where he remained throughout his life a liberal, reform-minded monarchist and a skeptic with respect to republican and democratic ideas.

In the Lettres philosophiques, Voltaire had suggested a more radical position with respect to human determinism, especially in his letter on Locke, which emphasized the materialist reading of the Lockean soul that was then a popular figure in radical philosophical discourse. Some readers singled out this part of the book as the major source of its controversy, and in a similar vein the very materialist account of “Âme,” or the soul, which appeared in volume 1 of Diderot and d'Alembert's Encyclopédie, was also a flashpoint of controversy. Voltaire also defined his own understanding of the soul in similar terms in his own Dictionnaire philosophique. What these examples point to is Voltaire's willingness, even eagerness, to publicly defend controversial views even when his own, more private and more considered writings often complicated the understanding that his more public and polemical writings insisted upon. In these cases, one often sees Voltaire defending less a carefully reasoned position on a complex philosophical problem than adopting a political position designed to assert his conviction that liberty of speech, no matter what the topic, is sacred and cannot be violated.

Voltaire never actually said “I disagree with what you say, but I will defend to the death your right to say it.” Yet the myth that associates this dictum with his name remains very powerful, and one still hears his legacy invoked through the redeclaration of this pronouncement that he never actually declared. Part of the deep cultural tie that joins Voltaire to this dictum is the fact that even while he did not write these precise words, they do capture, however imprecisely, the spirit of his philosophy of liberty. In his voluminous correspondence especially, and in the details of many of his more polemical public texts, one does find Voltaire articulating a view of intellectual and civil liberty that makes him an unquestioned forerunner of modern civil libertarianism. He never authored any single philosophical treatise on this topic, however, yet the memory of his life and philosophical campaigns was influential in advancing these ideas nevertheless. Voltaire's influence is palpably present, for example, in Kant's famous argument in his essay “What is Enlightenment?” that Enlightenment stems from the free and public use of critical reason, and from the liberty that allows such critical debate to proceed untrammeled. The absence of a singular text that anchors this linkage in Voltaire's collected works in no way removes the unmistakable presence of Voltaire's influence upon Kant's formulation.

2.2 Hedonism

Voltaire's notion of liberty also anchored his hedonistic morality, another key feature of Voltaire's Enlightenment philosophy. One vehicle for this philosophy was Voltaire's salacious poetry, a genre that both reflected in its eroticism and sexual innuendo the lived culture of libertinism that was an important feature of Voltaire's biography. But Voltaire also contributed to philosophical libertinism and hedonism through his celebration of moral freedom through sexual liberty. Voltaire's avowed hedonism became a central feature of his wider philosophical identity since his libertine writings and conduct were always invoked by those who wanted to indict him for being a reckless subversive devoted to undermining legitimate social order. Voltaire's refusal to defer to such charges, and his vigor in opposing them through a defense of the very libertinism that was used against him, also injected a positive philosophical program into these public struggles that was very influential. In particular, through his cultivation of a happily libertine persona, and his application of philosophical reason toward the moral defense of this identity, often through the widely accessible vehicles of poetry and witty prose, Voltaire became a leading force in the wider Enlightenment articulation of a morality grounded in the positive valuation of personal, and especially bodily, pleasure, and an ethics rooted in a hedonistic calculus of maximizing pleasure and minimizing pain. He also advanced this cause by sustaining an unending attack upon the repressive and, to his mind, anti-human demands of traditional Christian asceticism, especially priestly celibacy, and the moral codes of sexual restraint and bodily self-abnegation that were still central to the traditional moral teachings of the day.

This same hedonistic ethics was also crucial to the development of liberal political economy during the Enlightenment, and Voltaire applied his own libertinism toward this project as well. In the wake of the scandals triggered by Mandeville's famous argument in The Fable of the Bees (a poem, it should be remembered) that the pursuit of private vice, namely greed, leads to public benefits, namely economic prosperity, a French debate about the value of luxury as a moral good erupted that drew Voltaire's pen. In the 1730s, he drafted a poem called Le Mondain that celebrated hedonistic worldly living as a positive force for society, and not as the corrupting element that traditional Christian morality held it to be. In his Essay sur les moeurs he also joined with other Enlightenment historians in celebrating the role of material acquisition and commerce in advancing the progress of civilization. Adam Smith would famously make similar arguments in his founding tract of Enlightenment liberalism, On the Wealth of Nations, published in 1776. Voltaire was certainly no great contributor to the political economic science that Smith practiced, but he did contribute to the wider philosophical campaigns that made the concepts of liberty and hedonistic morality central to their work both widely known and more generally accepted.

The ineradicable good of personal and philosophical liberty is arguably the master theme in Voltaire's philosophy, and if it is, then two other themes are closely related to it. One is the importance of skepticism, and the second is the importance of empirical science as a solvent to dogmatism and the pernicious authority it engenders.

2.3 Skepticism

Voltaire's skepticism descended directly from the neo-Pyrrhonian revival of the Renaissance, and owes a debt in particular to Montaigne, whose essays wedded the stance of doubt with the positive construction of a self grounded in philosophical skepticism. Pierre Bayle's skepticism was equally influential, and what Voltaire shared with these forerunners, and what separated him from other strands of skepticism, such as the one manifest in Descartes, is the insistence upon the value of the skeptical position in its own right as a final and complete philosophical stance. Among the philosophical tendencies that Voltaire most deplored, in fact, were those that he associated most powerfully with Descartes who, he believed, began in skepticism but then left it behind in the name of some positive philosophical project designed to eradicate or resolve it. Such urges usually led to the production of what Voltaire liked to call “philosophical romances,” which is to say systematic accounts that overcome doubt by appealing to the imagination and its need for coherent explanations. Such explanations, Voltaire argued, are fictions, not philosophy, and the philosopher needs to recognize that very often the most philosophical explanation of all is to offer no explanation at all.

Such skepticism often acted as bulwark for Voltaire's defense of liberty since he argued that no authority, no matter how sacred, should be immune to challenge by critical reason. Voltaire's views on religion as manifest in his private writings are complex, and based on the evidence of these texts it would be wrong to call Voltaire an atheist, or even an anti-Christian so long as one accepts a broad understanding of what Christianity can entail. But even if his personal religious views were subtle, Voltaire was unwavering in his hostility to church authority and the power of the clergy. For similar reasons, he also grew as he matured ever more hostile toward the sacred mysteries upon which monarchs and Old Regime aristocratic society based their authority. In these cases, Voltaire's skepticism was harnessed to his libertarian convictions through his continual effort to use critical reason as a solvent for these “superstitions” and the authority they anchored. The philosophical authority of romanciers such as Descartes, Malebranche, and Leibniz was similarly subjected to the same critique, and here one sees how the defense of skepticism and liberty, more than any deeply held opposition to religiosity per se, was often the most powerful motivator for Voltaire.

From this perspective, Voltaire might fruitfully be compared with Socrates, another founding figure in Western philosophy who made a refusal to declaim systematic philosophical positions a central feature of his philosophical identity. Socrates's repeated assertion that he knew nothing was echoed in Voltaire's insistence that the true philosopher is the one who dares not to know and then has the courage to admit his ignorance publicly. Voltaire was also, like Socrates, a public critic and controversialist who defined philosophy primarily in terms of its power to liberate individuals from domination at the hands of authoritarian dogmatism and irrational prejudice. Yet while Socrates championed rigorous philosophical dialectic as the agent of this emancipation, Voltaire saw this same dialectical rationalism at the heart of the dogmatism that he sought to overcome. Voltaire often used satire, mockery and wit to undermine the alleged rigor of philosophical dialectic, and while Socrates saw this kind of rhetorical word play as the very essence of the erroneous sophism that he sought to alleviate, Voltaire cultivated linguistic cleverness as a solvent to the false and deceptive dialectic that anchored traditional philosophy.

2.4 Newtonian Empirical Science

Against the acceptance of ignorance that rigorous skepticism often demanded, and against the false escape from it found in sophistical knowledge—or what Voltaire called imaginative philosophical romances—Voltaire offered a different solution than the rigorous dialectical reasoning of Socrates: namely, the power and value of careful empirical science. Here one sees the debt that Voltaire owed to the currents of Newtonianism that played such a strong role in launching his career. Voltaire's own critical discourse against imaginative philosophical romances originated, in fact, with English and Dutch Newtonians, many of whom were expatriate French Huguenots, who developed these tropes as rhetorical weapons in their battles with Leibniz and European Cartesians who challenged the innovations of Newtonian natural philosophy. In his Principia Mathematica (1687; 2nd rev. edition 1713), Newton had offered a complete mathematical and empirical description of how celestial and terrestrial bodies behaved. Yet when asked to explain how bodies were able to act in the way that he mathematically and empirically demonstrated that they did, Newton famously replied “I feign no hypotheses.” From the perspective of traditional natural philosophy, this was tantamount to hand waving since offering rigorous causal accounts of the nature of bodies in motion was the very essence of this branch of the sciences. Newton's major philosophical innovation rested, however, in challenging this very epistemological foundation, and the assertion and defense of Newton's position against its many critics, not least by Voltaire, became arguably the central dynamic of philosophical change in the first half of the eighteenth century.

While Newtonian epistemology admitted of many variations, at its core rested a new skepticism about the validity of apriori rationalist accounts of nature and a new assertion of brute empirical fact as a valid philosophical understanding in its own right. European Natural philosophers in the second half of the seventeenth century had thrown out the metaphysics and physics of Aristotle with its four part causality and teleological understanding of bodies, motion and the cosmic order. In its place, however, a new mechanical causality was introduced that attempted to explain the world in equally comprehensive terms through the mechanisms of an inert matter acting by direct contact and action alone. This approach lead to the vortical account of celestial mechanics, a view that held material bodies to be swimming in an ethereal sea whose action pushed and pulled objects in the manner we observe. What could not be observed, however, was the ethereal sea itself, or the other agents of this supposedly comprehensive mechanical cosmos. Yet rationality nevertheless dictated that such mechanisms must exist since without them philosophy would be returned to the occult causes of the Aristotelian natural tendencies and teleological principles. Figuring out what these point-contact mechanisms were and how they worked was, therefore, the charge of the new mechanical natural philosophy of the late seventeenth century. Figures such as Descartes, Huygens, and Leibniz established their scientific reputations through efforts to realize this goal.

Newton pointed natural philosophy in a new direction. He offered mathematical analysis anchored in inescapable empirical fact as the new foundation for a rigorous account of the cosmos. From this perspective, the great error of both Aristotelian and the new mechanical natural philosophy was its failure to adhere strictly enough to empirical facts. Vortical mechanics, for example, claimed that matter was moved by the action of an invisible agent, yet this, the Newtonians began to argue, was not to explain what is really happening but to imagine a fiction that gives us a speciously satisfactory rational explanation of it. Natural philosophy needs to resist the allure of such rational imaginings and to instead deal only with the empirically provable. Moreover, the Newtonians argued, if a set of irrefutable facts cannot be explained other then by accepting the brute facticity of their truth, this is not a failure of philosophical explanation so much as a devotion to appropriate rigor. Such epistemological battles became especially intense around Newton's theory of universal gravitation. Few questioned that Newton had demonstrated an irrefutable mathematical law whereby bodies appear to attract one another in relation to their masses and in inverse relation to the square of the distance between them. But was this rigorous mathematical and empirical description a philosophical account of bodies in motion? Critics such as Leibniz said no, since mathematical description was not the same thing as philosophical explanation, and Newton refused to offer an explanation of how and why gravity operated the way that it did. The Newtonians countered that phenomenal descriptions were scientifically adequate so long as they were grounded in empirical facts, and since no facts had yet been discerned that explained what gravity is or how it works, no scientific account of it was yet possible. They further insisted that it was enough that gravity did operate the way that Newton said it did, and that this was its own justification for accepting his theory. They further mocked those who insisted on dreaming up chimeras like the celestial vortices as explanations for phenomena when no empirical evidence existed to support of such theories.

The previous summary describes the general core of the Newtonian position in the intense philosophical contests of the first decades of the eighteenth century. It also describes Voltaire's own stance in these same battles. His contribution, therefore, was not centered on any innovation within these very familiar Newtonian themes; rather, it was his accomplishment to become a leading evangelist for this new Newtonian epistemology, and by consequence a major reason for its widespread dissemination and acceptance in France and throughout Europe. A comparison with David Hume's role in this same development might help to illuminate the distinct contributions of each. Both Hume and Voltaire began with the same skepticism about rationalist philosophy, and each embraced the Newtonian criterion that made empirical fact the only guarantor of truth in philosophy. Yet Hume's target remained traditional philosophy, and his contribution was to extend skepticism all the way to the point of denying the feasibility of transcendental philosophy itself. This argument would famously awake Kant's dogmatic slumbers and lead to the reconstitution of transcendental philosophy in new terms, but Voltaire had different fish to fry. His attachment was to the new Newtonian empirical scientists, and while he was never more than a dilettante scientist himself, his devotion to this form of natural inquiry made him in some respects the leading philosophical advocate and ideologist for the new empirico-scientific conception of philosophy that Newton initiated.

For Voltaire (and many other eighteenth-century Newtonians) the most important project was defending empirical science as an alternative to traditional natural philosophy. This involved sharing in Hume's critique of abstract rationalist systems, but it also involved the very different project of defending empirical induction and experimental reasoning as the new epistemology appropriate for a modern Enlightened philosophy. In particular, Voltaire fought vigorously against the rationalist epistemology that critics used to challenge Newtonian reasoning. His famous conclusion in Candide, for example, that optimism was a philosophical chimera produced when dialectical reason remains detached from brute empirical facts owed a great debt to his Newtonian convictions. His alternative offered in the same text of a life devoted to simple tasks with clear, tangible, and most importantly useful ends was also derived from the utilitarian discourse that Newtonians also used to justify their science. Voltaire's campaign on behalf of smallpox inoculation, which began with his letter on the topic in the Lettres philosophiques, was similarly grounded in an appeal to the facts of the case as an antidote to the fears generated by logical deductions from seemingly sound axiomatic principles. All of Voltaire's public campaigns, in fact, deployed empirical fact as the ultimate solvent for irrational prejudice and blind adherence to preexisting understandings. In this respect, his philosophy as manifest in each was deeply indebted to the epistemological convictions he gleaned from Newtonianism.

2.5 Toward Science without Metaphysics

Voltaire also contributed directly to the new relationship between science and philosophy that the Newtonian revolution made central to Enlightenment modernity. Especially important was his critique of metaphysics and his argument that it be eliminated from any well-ordered science. At the center of the Newtonian innovations in natural philosophy was the argument that questions of body per se were either irrelevant to, or distracting from, a well focused natural science. Against Leibniz, for example, who insisted that all physics begin with an accurate and comprehensive conception of the nature of bodies as such, Newton argued that the character of bodies was irrelevant to physics since this science should restrict itself to a quantified description of empirical effects only and resist the urge to speculate about that which cannot be seen or measured. This removal of metaphysics from physics was central to the overall Newtonian stance toward science, but no one fought more vigorously for it, or did more to clarify the distinction and give it a public audience than Voltaire.

The battles with Leibnizianism in the 1740s were the great theater for Voltaire's work in this regard. In 1740, responding to Du Châtelet's efforts in her Institutions de physiques to reconnect metaphysics and physics through a synthesis of Leibniz with Newton, Voltaire made his opposition to such a project explicit in reviews and other essays he published. He did the same during the brief revival of the so-called “vis viva controversy” triggered by du Châtelet's treatise, defending the empirical and mechanical conception of body and force against those who defended Leibniz's more metaphysical conception of the same thing. In the same period, Voltaire also composed a short book entitled La Metaphysique de Newton, publishing it in 1740 as an implicit counterpoint to Châtelet's Institutions. This tract did not so much articulate Newton's metaphysics as celebrate the fact that he avoided practicing such speculations altogether. It also accused Leibniz of becoming deluded by his zeal to make metaphysics the foundation of physics. In the definitive 1745 edition of his Éléments de la philosophie de Newton, Voltaire also appended his tract on Newton's metaphysics as the book's introduction, thus framing his own understanding of the relationship between metaphysics and empirical science in direct opposition to Châtelet's Leibnizian understanding of the same. He also added personal invective and satire to this same position in his indictment of Maupertuis in the 1750s, linking Maupertuis's turn toward metaphysical approaches to physics in the 1740s with his increasingly deluded philosophical understanding and his authoritarian manner of dealing with his colleagues and critics.

While Voltaire's attacks on Maupertuis crossed the line into ad hominem, at their core was a fierce defense of the way that metaphysical reasoning both occludes and deludes the work of the physical scientist. Moreover, to the extent that eighteenth-century Newtonianism provoked two major trends in later philosophy, first the reconstitution of transcendental philosophy à la Kant through his “Copernican Revolution” that relocated the remains of metaphysics in the a priori categories of reason, and second, the marginalization of metaphysics altogether through the celebration of philosophical positivism and the anti-speculative scientific method that anchored it, Voltaire should be seen as a major progenitor of the latter. By also attaching what many in the nineteenth century saw as Voltaire's proto-positivism to his celebrated campaigns to eradicate priestly and aristo-monarchical authority through the debunking of the “irrational superstitions” that appeared to anchor such authority, Voltaire's legacy also cemented the alleged linkage that joined positivist science on the one hand with secularizing disenchantment and dechristianization on the other. In this way, Voltaire should be seen as the initiator of a philosophical tradition that runs from him to Auguste Comte and Charles Darwin, and then on to Karl Popper and Richard Dawkins in the twentieth century.


Primary Literature

Because of Voltaire's celebrity, efforts to collect and canonize his writings began immediately after his death, and still continue today. The result has been the production of three major collections of his writings including his vast correspondence, the last unfinished. Together these constitute the authoritative corpus of Voltaire's written work.

  • Oeuvres complètes de Voltaire, edited by A. Beuchot. 72 vols. Paris: Lefevre, 1829–1840.
  • Oeuvres complètes de Voltaire, edited by L.E.D. Moland and G. Bengesco. 52 vols. Paris: Garnier Frères, 1877–1885.

Secondary Literature

The scholarly literature on Voltaire is vast, and growing larger every day. The summary here, therefore, will be largely restricted to scholarly books, with only a few articles of singular import listed. The Voltaire Foundation's series Studies on Voltaire and the Eighteenth Century changed its name in 2013 to Oxford University Studies on Enlightenment. The original series published over 450 volumes, many related to Voltaire, and while the new title reflects a change toward a broader publishing agenda, it remains, along with Cahier Voltaire published by La Fondation Voltaire à Ferney, the best periodical source for new scholarship on Voltaire.
