François-Marie d'Arouet (1694--1778), better known by his pen name Voltaire, was a French writer and public activist who played a singular role in defining the eighteenth-century movement called the Enlightenment. At the center of his work was a new conception of philosophy and the philosopher that in several crucial respects influenced the modern concept of each. Yet in other ways Voltaire was not a philosopher at all in the modern sense of the term. He wrote as many plays, stories, and poems as patently philosophical tracts, and he in fact directed many of his critical writings against the philosophical pretensions of recognized philosophers such as Leibniz, Malebranche, and Descartes. He was, however, a vigorous defender of a conception of natural science that served in his mind as the antidote to vain and fruitless philosophical investigation. In clarifying this new distinction between science and philosophy, and especially in fighting vigorously for it in public campaigns directed against the perceived enemies of fanaticism and superstition, Voltaire pointed modern philosophy down several paths that it subsequently followed. 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 from 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.
