 The Enlightenment

The Enlightenment was both a movement and a state of mind. The term represents a phase in theintellectual history of Europe, but italso serves to define programs of reform in which influential literati, inspired by a common faith in the possibility of a better world, outlined specific targets for criticism and proposals for action. The special significance of the Enlightenment lies in its combination of principle and pragmatism. Consequently, it still engenders controversy about its character and achievements. Two main questions and, relating to each, two schools of thought can be identified. Was the Enlightenment the preserve of an elite, centred on Paris, or a broad current of opinion that the  philosophes, to some extent, represented and led? Was it primarily a French movement, having therefore a degree of coherence, or an international phenomenon, having as many facets as there were countries affected? Although most modern interpreters incline to the latter view in both cases, there is still a case for the French emphasis, given the genius of a number of the philosophes and their associates. Unlike other terms applied by historians to describe a phenomenon that they see more clearly than could contemporaries, it was used and cherished by those who believed in the power of mind to liberate and improve. Bernard de Fontenelle, popularizer of the scientific discoveries that contributed to the climate of optimism, wrote in 1702 anticipating “a century which will become more enlightened dayby day, so that all previous centuries will be lost in darkness by comparison.” Reviewing the experience in 1784, Immanuel Kantsaw an emancipation from superstition and ignorance as having been the essential characteristic of the Enlightenment.

Before Kant's death the spirit of the siècle de lumière (literally, “century of light”) had been spurned by Romantic idealists, its confidence in man's sense of what was right and good mocked by revolutionary terror and dictatorship, and its rationalism decried as being complacent or downright inhumane. Even its achievements were critically endangered by the militant nationalism of the 19th century. Yet much of the tenor of the Enlightenment did survive in the liberalism, toleration, and respect for law that have persisted in European society. There was therefore no abrupt end or reversal of enlightened values.

Nor had there been such a sudden beginning as is conveyed by the critic Paul Hazard's celebrated aphorism: “One moment the French thought like Bossuet; the next moment like Voltaire.” Theperceptions and propaganda of the philosophes have led historians to locate the Age of Reason within the 18th century or,more comprehensively, between the two revolutions—the English of 1688 and the French of 1789—but in conception it should be traced to the humanism of the Renaissance, which encouraged scholarly interest in classical texts and values. It wasformed by the complementary methods of the Scientific Revolution, the rational and the empirical. Its adolescence belongs to the two decades before and after 1700 when writers such as Jonathan Swift were employing “the artillery of words” toimpress the secular intelligentsia created by the growth in affluence, literacy, and publishing. Ideas and beliefs were tested wherever reason and research could challenge traditional authority.


Sources of Enlightenment thought

In a cosmopolitan culture it was the preeminence of the  French language that enabled Frenchmen of the 17th century to lay thefoundations of cultural ascendancy and encouraged the philosophes to act as the tutors of 18th-century Europe. The notion of a realm of philosophy superior to sectarian or national concerns facilitated the transmission of ideas. “I flatter myself,” wrote  Denis Diderot to the Scottish philosopher David Hume, “that I am, like you, citizen of the great city of the world.” “A philosopher,” wrote  Edward Gibbon, “may consider Europe as a great republic, whose various inhabitants have attained almost the same level of politeness and cultivation.” This magisterial pronouncement by the author of The Decline and Fall of the Roman Empire (1776–88) recalls the common source: the knowledge of classical literature.

The scholars of the Enlightenment recognized a joint inheritance,  Christian as well as classical. In rejecting, or at least reinterpreting, the one and plundering the other, they had the confidence of those who believed they were masters of their destiny. They felt an affinity with the classical world and saluted the achievement of the  Greeks, who discovered a regularity in nature and its governing principle, the reasoning mind, as well asthat of the  Romans, who adopted Hellenic culture while contributing a new order and style: on their law was founded much of church and civil law. Steeped in the ideas and languageof the classics but unsettled in beliefs, some Enlightenment thinkers found an alternative to Christian faith in the form of a neo-paganism. The morality was based on reason; the literature, art, and architecture were already supplying rules and standardsfor educated taste.

The first chapter of  Voltaire's Siècle de Louis XIV specified the “four happy ages”: the centuries of Pericles and Plato, of Cicero and Caesar, of the Medicean Renaissance, and, appositely, of Louis XIV. The contrast is with “the ages of belief,” which were wretched and backward. Whether denouncing Gothic taste or clerical fanaticism, writers of the Enlightenment constantly resort to images of relapse and revival. Typically, Jean d'Alembert wrote in the Preliminary Discourse to the Encyclopédie of a revival of letters, regeneration of ideas, and return to reason and good taste. The philosophes knew enough to be sure that they were entering a new golden age through rediscovery of the old but not enough to have misgivings about a reading of history which, being grounded in a culture that had self-evident value, provided ammunition for the secular crusade.


The role of  science and mathematics

“The new philosophy puts all in doubt,” wrote the poet John Donne. Early 17th-century poetry and drama abounded in expressions of confusion and dismay about the world, God, and man. The gently questioning essays of the 16th-century French philosopher  Michel de Montaigne, musing on human folly and fanaticism, continued to be popular long after his time, for they were no less relevant to the generation that suffered from the Thirty Years' War. Unsettling scientific views were gaining a hold. As the new astronomy of Copernicus and Galileo, with its heliocentric view, was accepted, the firm association between religious beliefs, moral principles, and the traditional scheme of nature was shaken. In this process,  mathematics occupied the central position. It was, in the words of  René Descartes, “the general science which should explain all that can be known about quantity and measure, considered independently of any application to a particular subject.” It enabled its practitioners to bridge gaps between speculation and reasonable certainty: Johannes Kepler thus proceeded from his study of conic sections to the laws of planetary motion. When, however, Fontenelle wrote of Descartes, “Sometimes one man gives the tone to a whole century,” it was not merely of his mathematics that he was thinking. It was the system and philosophy that Descartes derived from the application of mathematical reasoning to the mysteries of the world—all that is meant by  Cartesianism—which was so influential. The method expounded in his Discourse on Method (1637) was one of doubt: all was uncertain until established by reasoning from self-evident propositions, on principles analogous to those of geometry. It wasserviceable in all areas of study. There was a mechanistic model for all living things.

A different track had been pursued by  Francis Bacon, the great English lawyer and savant, whose influence eventually proved as great as that of Descartes. He called for a new science, to be based on organized and collaborative experiment with a systematic recording of results. General laws could be established only when research had produced enough data and then by  inductive reasoning, which, as described in his Novum Organum (1620), derives from “particulars, rising by a gradual and unbroken ascent, so that it arrives at the most general axioms last of all.” These must be tried and proved by further experiments. Bacon's method could lead to the accumulation of knowledge. It also was self-correcting. Indeed, it was in some ways modern in its practical emphasis. Significantly, whereas thedevout humanist Thomas More had placed his Utopia in a remotesetting, Bacon put New Atlantis (1627) in the future. “Knowledge is power,” he said, perhaps unoriginally but with the conviction that went with a vision of mankind gaining mastery over nature. Thus were established the two poles of scientific endeavour, the rational and the empirical, between which enlightened man was to map the ground for a better world.

Bacon's inductive method is flawed through his insufficient emphasis on hypothesis. Descartes was on strong ground when he maintained that philosophy must proceed from what is definable to what is complex and uncertain. He wrote in French rather than the customary Latin so as to exploit its value as a vehicle for clear and logical expression and to reach a wider audience. Cartesian rationalism, as applied to theology, for example by Nicholas Malebranche, who set out to refute the pantheism of Benedict de Spinoza, was a powerful solvent of traditional belief: God was made subservient to reason. While Descartes maintained his hold on French opinion, across the Channel  Isaac Newton, a prodigious mathematician and a resourceful and disciplined experimenter, was mounting a crucial challenge. His Philosophiae Naturalis Principia Mathematica (1687; Mathematical Principles of Natural Philosophy) ranks with the Discourse on Method in authority and influence as a peak in the 17th-century quest for truth. Newton did not break completely with Descartes and remained faithful tothe latter's fundamental idea of the universe as a machine. But Newton's machine operated according to a series of laws, the essence of which was that the principle of  gravitation was everywhere present and efficient. The onus was on the Cartesians to show not only that their mechanics gave a truer explanation but also that their methods were sounder.  Christiaan Huygens was both a loyal disciple of Descartes and a formidable mathematician and inventor in his own right, who had worked out the first tenable theory of  centrifugal force. His dilemma is instructive. He acknowledged that Newton's assumption of forces acting between members of the solar system was justified by the correct conclusions he drew from it, but he would not go on to accept that attraction was affecting every pair of particles, however minute. When Newton identified gravitation as a property inherent in corporeal matter, Huygens thought that absurd and looked for an agent acting constantly according to certain laws. Some believed that Newton was returning to “occult” qualities. Eccentricities apart, his views were not easy to grasp; those who actually read the Principia found it painfully difficult. Cartesianism was more accessible and appealing.

Gradually, however, Newton's work won understanding. one medium, ironically, was an outstanding textbook of Cartesian physics, Jacques Rohault's Traité de physique (1671), with detailed notes setting out Newton's case. In 1732 Pierre-Louis de Mauperthuis put the Cartesians on the defensive by his defense of Newton's right to employ a principle the cause of which was yet unknown. In 1734, in his Philosophical Letters, Voltaire introduced Newton as the “destroyer of the system of Descartes.” His authority clinched the issue. Newton's physics was justified by its successful application in different fields. The return of Halley's comet was accurately predicted. Charles Coulomb's torsion balance proved that Newton's law of inverse squares was valid for electromagnetic attraction. Cartesianism reduced nature to a set of habits within a world of rules; the new attitude took note of accidents and circumstances. Observation and experiment revealed nature as untidy, unpredictable—a tangle of conflicting forces. In classical theory, reason was presumed to be common to all human beings and its laws immutable. In Enlightenment Europe, however, there was a growing impatience with systems. The most creative of scientists, such as Boyle, Harvey, and Leeuwenhoek, found sufficient momentum for discovery on science's front line. The controversy was creative because both rational and empirical methods were essential to progress. Like the literary battle between the “ancients” and the “moderns” or the theological battle between Jesuits and Jansenists, the scientific debate was aschool of advocacy.

If Newton was supremely important among those who contributed to the climate of the Enlightenment, it is because his new system offered certainties in a world of doubts. The beliefspread that Newton had explained forever how the universe worked. This cautious, devout empiricist lent the imprint of genius to the great idea of the Enlightenment: that man, guided by the light of reason, could explain all natural phenomena and could embark on the study of his own place in a world that was no longer mysterious. Yet he might otherwise have been aware more of disintegration than of progress or of theories demolished than of truths established. This was true even within the expanding field of the physical sciences. To gauge the mood of the world of intellect and fashion, of French salons or of such institutions as the Royal Society, it is essential tounderstand what constituted the crisis in the European mind of the late 17th century.

At the heart of the crisis was the critical examination of  Christianfaith, its foundations in the Bible, and the authority embodied in the church. In 1647 Pierre Gassendi had revived the atomistic philosophy of Lucretius, as outlined in on the Nature of Things. He insisted on the Divine Providence behind Epicurus' atoms andvoids. Critical examination could not fail to be unsettling becausethe Christian view was not confined to questions of personal belief and morals, or even history, but comprehended the entire nature of God's world. The impact of scientific research must be weighed in the wider context of an intellectual revolution. Different kinds of learning were not then as sharply distinguished, because of their appropriate disciplines and terminology, as they are in an age of specialization. At that time philomaths could still be polymaths. Newton's contemporary,  Gottfried Wilhelm Leibniz—whose principal contribution to philosophy was that substance exists only in the form of monads,each of which obeys the laws of its own self-determined development while remaining in complete accord with all the rest—influenced his age by concluding that since God contrived the universal harmony this world must be the best of all possible worlds. He also proposed legal reforms, invented a calculating machine, devised a method of the calculus independent of Newton's, improved the drainage of mines, and laboured for the reunification of the Roman Catholic and Lutheran churches.


The influence of Locke

The writing of  John Locke, familiar to the French long before the eventual victory of his kind of empiricism, further reveals the range of interests that an educated man might pursue and its value in the outcome: discrimination, shrewdness, and originality. The journal of Locke's travels in France (1675–79) is studded with notes on botany, zoology, medicine, weather, instruments of all kinds, and statistics, especially those concerned with prices and taxes. It is a telling introduction to theworld of the Enlightenment, in which the possible was always as important as the ideal and physics could be more important than metaphysics. Locke spent the years from 1683 to 1689 in Holland, in refuge from high royalism. There he associated with other literary exiles, who were united in abhorrence of Louis XIV'sreligious policies, which culminated in the revocation of the Edictof Nantes (1685) and the flight of more than 200,000 Huguenots. During this time Locke wrote the Essay on Toleration(1689). The coincidence of the Huguenot dispersion with the English revolution of 1688–89 meant a cross-fertilizing debate in a society that had lost its bearings. The avant-garde accepted Locke's idea that the people had a sovereign power and that the prince was merely a delegate. His  Second Treatise of Civil Government (1690) offered a theoretical justification for a contractual view of monarchy on the basis of a revocable agreement between ruler and ruled. It was, however, his writingsabout education, toleration, and morality that were most influential among the philosophes, for whom his political theoriescould be only of academic interest. Locke was the first to treat  philosophy as purely critical inquiry, having its own problems butessentially similar to other sciences. Voltaire admired what Lockecalled his “historical plain method” because he had not written “a romance of the soul” but offered “a history of it.” The avowed object of his Essay Concerning Human Understanding (1690) was “to inquire into the original, certainty, and extent of human knowledge; together with the grounds and degrees of belief, opinion, and assent.” For Locke, the mind derives the materials ofreason and knowledge from experience. Unlike Descartes' view that man could have innate ideas, in Locke's system knowledge consists of ideas imprinted on the mind through observation of external objects and reflection on the evidence provided by the  senses  . Moral values, Locke held, are derived from sensations of pleasure or pain, the mind labeling good what experience shows to give pleasure. There are no innate ideas; there is no innate depravity.

Though he suggested that souls were born without the idea of God, Locke did not reject Christianity. Sensationalism, he held, was a God-given principle that, properly followed, would lead to conduct that was ethically sound. He had, however, opened a way to disciples who proceeded to conclusions that might have been far from the master's mind. one such was the Irish bishop  George Berkeley who affirmed, in his Treatise on the Principles of Human Knowledge (1710), that there was no proof that matter existed beyond the idea of it in the mind. Most philosophers afterDescartes decided the question of the dualism of mind and matter by adopting a materialist position; whereas they eliminated mind, Berkeley eliminated matter—and he was therefore neglected. Locke was perhaps more scientific and certainly more in tune with the intellectual and practical concerns of the age. Voltaire presented Locke as the advocate ofrational faith and of sensationalist psychology; Locke's posthumous success was assured. In the debate over  moral values, Locke provided a new argument for toleration. Beliefs, like other human differences, were largely the product of environment. Did it not therefore follow that moral improvement should be the responsibility of society? Finally, since human irrationality was the consequence of false ideas, instilled by faultyschooling, should not education be a prime concern of rulers? To pose those questions is to anticipate the agenda of the Enlightenment.


The proto-Enlightenment

If Locke was the most influential philosopher in the swirling debates of fin de siècle Holland, the most prolific writer and educator was  Pierre Bayle, whom Voltaire called “the first of the  skeptical philosophers.” He might also be called the first of the  encyclopaedists, for he was more publicist than philosopher, eclectic in his interests, information, and ideas. The title Nouvelles de la république des lettres (1684–87) conveys the method and ideal of this superior form of journalism. Bayle's Historical Dictionary (1697) exposed the fallacies and deceits of the past by the plausible method of biographical articles. “The grounds of doubting are themselves doubtful; we must thereforedoubt whether we ought to doubt.” Lacking a sound criterion of truth or a system by which evidence could be tested but hating dogma and mistrusting authority, Bayle was concerned with the present state of knowledge. He may have been as much concerned with exposing the limitations of human reason as withattacking superstition. Translated and abridged, as, for example, by order of Frederick II of Prussia, the Dictionary became the skeptic's bible. The effect of Bayle's work and that of others less scrupulous, pouring from the presses of the Netherlands and Rhineland and easily penetrating French censorship, could not fail to be broadly subversive.

Bayle's seminal role in the cultural exchange of his time points to the importance of the   Dutch Republic in the 17th century. Because Holland contributed little to science, philosophy, or even art at the time of the philosophes, though enviable enough in the tranquil lives of many of its citizens, its golden 17th century tends to be overlooked in traditional accounts of the Enlightenment. Wealth derived from trade, shipping, and finance and the toleration that attracted Sephardic Jews, Protestants from Flanders and France, and other refugees or simply those who sought a relatively open society combined to create a climate singularly favourable to enterprise and creativity. It was urban, centring on Amsterdam, and it was characterized by a rich artistic life created by painters who worked to please patrons who shared their values. It was pervaded by a scientific spirit. Pieter de Hooch's search for new ways of portraying light, Spinoza's pursuit of a rational system that would comprehend all spiritual truth. Antony van Leeuwenhoek's use of the microscope to reveal the hidden and minute, Hermann Boerhaave's dissection of the human corpse, Jan Blaeuw's accuracy in the making of maps or Huygens' in the new pendulum clock—each represents that passion for discovery that put 17th-century Holland in a central position between the Renaissance and the Enlightenment, with some of the creative traits of both periods. Its spirit is epitomized in theuniversity of Leiden, which attracted students from throughout Europe by its excellence in medicine and law and its relative freedom from ecclesiastical authority.

It was fitting, therefore, that much of the writing that helped form the Enlightenment emanated from the printing presses of the Huguenot emigré Louis Elsevier at Amsterdam and Leiden. Bayle's skepticism belongs to the time when dust was still rising from the collapsing structures of the past, obscuring such patterns of thought as would eventually emerge. There wasno lack of material for them. Not only did learning flourish in the cultural common market that served the needs of those who led or followed intellectual fashions; also important, though harder tomeasure, was the influence of the new relativism, grounded in observable facts about an ever-widening world. It was corrosive alike of Cartesian method, classical regulation, and traditional theology. Of Descartes, Huygens had written that he had substituted for old ideas “causes for which one can comprehend all that there is in nature.”

Allied to that confidence in the power of reason was a prejudice against knowledge that might distort argument.  Blaise Pascal had perfectly exemplified that rationalist frame of mind prone to introspection, which in his case—that of mathematical genius and literary sensibility in rare combination—produced some of the finest writing of his day. But the author of the Pensées (1669) was reluctant to travel: “All the ills that affect a man proceed from one cause, namely that he has not learned to sit quietly and contentedly in one room.” Again, the object of the protagonists of the prevailing classicism had been to establish rules: for language (the main role of the Académie), for painting (as in the work of Nicolas Poussin), even for the theatre, where  Jean Racine's plays of heightened feeling and pure conflict of ideal or personality gain effect by being constrained within the framework of their Greek archetypes.


History and social thought

Order, purity, clarity: such were the classical ideals. They had dominated traditional  theology as represented by its last great master,  Jacques-Bénigne Bossuet. His Politique tirée des propres paroles de l'Écriture sainte (“Statecraft Drawn from the Very Words of the Holy Scriptures”) and Discours sur l'histoire universelle offered a worldview and a history based on the Old Testament. Bossuet believed in the unity of knowledge as so many branches of  Christian truth. His compelling logic and magisterial writing had a strong influence. When, however, the hypotheses were tested and found wanting, the very comprehensiveness of the system ensured that its collapse was complete. Bossuet had encouraged Richard Simon when he set out to refute Protestantism through historical study of the  Bible but was shocked when he saw where it led. Inevitably, scholarship revealed inconsistencies and raised questions about the way that the Bible should be treated: if unreliable as history, then how sound was the basis for theology? Simon's works were banned in 1678, but Dutch printers ensured their circulation. Nocensorship could prevent the development of historical method, which was making a place for itself in the comprehensive search for truth. With Edward Gibbon (himself following the example of the 17th-century giants of church history), Jean Mabillon, and Louis Tillemont historians were to become more skilled and scrupulous in the use of evidence. The philosophes characteristically believed that history was becoming a science because it was subject to philosophical method. It also was subject to the prevailing materialist bias, which is why, scholarly though individual writers like David Hume might be, the Enlightenment was in some respects vulnerable to fresh insights about man—such as those of Étienne Bonnot de Condillac, who believed that human beings could be molded for their own good—and further research into the past—which, for Claude-Adrien Helvétius, was simply the worthless veneration of ancient laws and customs.

In 1703 Baron de Lahontan introduced the idea of the  “noble savage,” who led a moral life in the light of natural religion. In relative terms, the uniquely God-given character of European values was questioned; Louis XIV's persecution of the Huguenotsand Jansenists offered an unappealing example. Philosophers were provided, through the device of voyages imaginaires, with new insights and standards of reference. As Archbishop  Fénelon was to show in Télémaque (1699)—where the population of his imaginary republic of Salente was engaged in farming and the ruler, renouncing war, sought to increase the wealth of the kingdom—a utopian idyll could be a vehicle for criticism of contemporary institutions. A bishop and sentimental aristocrat, heir to the tradition of Christian agrarianism, might seem an unlikely figure to appear in the pantheon of the Enlightenment. But his readers encountered views about the obligations as well as rights of subjects that plainly anticipate its universalism, as in the Dialogue des morts: “Each individual owesincomparably more to the human race, the great fatherland, than to the country in which he is born.”


The language of the Enlightenment

It is easier to identify intellectual trends than to define enlightened views, even where, as in France, there was a distinct and self-conscious movement, which had by mid-century the characteristics of a party. Clues can be found in the use commonly made of certain closely related cult words such as  Reason, Nature, and  Providence. From having a sharp, almost technical sense in the work of Descartes, Pascal, and Spinoza, reason came to mean something like common sense, along with strongly pejorative assumptions about things not reasonable. ForVoltaire, the reasonable were those who believed in progress: he lived “in curious times and amid astonishing contrasts: reason onthe one hand, the most absurd fanaticism on the other.” Nature in the post-Newtonian world became a system of intelligible forces that grew as the complexity of matter was explored and the diversity of particular species discovered. It led to the pantheism of the Irish writer John Toland, for whom nature replaced God, and to the absolute doubt of Julien La Mettrie, who in L'Homme machine (1747) took the position that nothing about nature or its causes was known. In England, in the writing of Lord Shaftesbury and David Hartley, nature served the cause of sound morals and rational faith. one of the foremost theologians,  Joseph Butler, author of the Analogy of Religion (1736), tested revelation against nature and in so doing erased the troublesome distinction in a manner wholly satisfying to those who looked for assurance that God could be active in the world without breaking the laws of its being. Finally, to  Jean-Jacques Rousseau, nature—the word that had proved so useful to advocates of an undogmatic faith, of universal principles of law or even, in the hands of the physiocrats, the “natural,” or market, economy—acquired a new resonance. In his Discourse on the Origin of Inequality (1755), he wrote: “We cannot desire or fear anything, except from the idea of it, or from the simple impulse of nature.” Nature had become the primal condition of innocence in which man was whole—not perfect, but imbued with virtues that reflected the absence of restraints.

Along with the new view of the universe grew belief in the idea ofa benign Providence, which could be trusted because it was visibly active in the world. Writers sought to express their sense of God's benevolent intention as manifest in creation. To the Abbé Pluche domestic animals were not merely docile but naturally loved humanity. Voltaire, equally implausibly, observed of mountain ranges that they were “a chain of high and continuous aqueducts which, by their apertures allow the rivers and arms of the sea the space which they need to irrigate the land.” The idea of Providence could degenerate into the fatuous complacency that Voltaire himself was to deride and against which—in particular, the idea that the universe was just a vast theatre for the divine message— Samuel Taylor Coleridge was memorably to rebel.  Faith, wrote the English poet, “could not be intellectually more evident without being morally less effective; without counteracting its own end by sacrificing the life of faith to the cold mechanism of a worthless because compulsory assent.” So the Enlightenment can be seen to be carrying the seeds of its own disintegration. The providential idea was based on unscientific assumptions in an age in which scientists, favoured by a truce with men of religion, were free to pursue researches that revealed an untidier, therefore less comforting, world. Newton had argued, from such problems as irregularities in the orbit of planets, that divine intervention was necessary to keep the solar system operating regularly. D'Alembert found, however, that such problems were self-correcting. From being the divine mechanic had God now become the divine spectator?

No less unsettling were the findings of geologists.  Jean-Étienne Guettard concluded that the evidence of fossils found in the volcanic hills of the Puy de Dôme in south-central France conflicted with the time scheme of the Old Testament. Whether, like the Count de Buffon, they attributed to matter a form of life, speculated about life as a constant, shapeless flux, or postulated a history of the world that had evolved over an immensely long time, scientists were dispensing with God as a necessary factor in their calculations. Some theologians sought compromise, while others retreated, looking to a separate world of intuitive understanding for the justification of faith. Joseph Butler pointed to conscience, the voice of God speaking to the human soul. He deplored the enthusiasm that characterized the tireless preaching of John Wesley and his message of the love of God manifested in Christ. “A true and living faith in God,” Butler declared, “is inseparable from a sense of pardon from all past andfreedom from all present sins.” It was not the freedom understood by the philosophes, but it touched hearts and altered lives. Meanwhile the path of reason was open for the avowed atheism of  Baron d'Holbach, who declared in his Système de la nature (1770; “The System of Nature”) that there was no divine purpose: “The whole cannot have an object for outside itself there is nothing towards which it can tend.” Another approach was taken by  David Hume, author of Treatise on Human Nature (1739) and the Dialogues Concerning Natural Religion (1779). The notion of miracles was repugnant to reason, but he was content to leave religion as a mystery, to be a skeptic about skepticism, and to deny that man could reach objective knowledge of any kind.

These may appear to have been intellectual games for the few. Itcould only be a privileged, relatively leisured minority, even among the educated, who actively participated in debate or could even follow the reasoning. The impact was delayed; it was also uneven. In Dr. Johnson's England the independence bestowed by the Anglican clergyman's freehold and the willingness of the established church to countenance rational theology created a shock absorber in the form of the  Broad Church. In Protestant countries criticism tended to be directed toward amending existing structures: there was a pious as well as an impious Enlightenment. Among  Roman Catholic countries  France's situation was in some ways unique. Even there orthodox doctrines remained entrenched in such institutions as the Sorbonne; some bishops might be worldly but others were conscientious; monasteries decayed but parish life was vital and curés (parish priests) well trained. Nor was theologyneglected: in 1770, French publishers brought out 70 books in defense of the faith. Of course the philosophes, endowed with the talents and the means to mount sustained campaigns, ensured that the question of religion remained high on the agenda. There was also a ready sale for writers who sought to apply the rational and experimental methods to what Hume was to call the science of man.


Man and society

Chief among them was  Charles de Secondat de Montesquieu. His presidency in the parlement of Bordeaux supported the career of a litterateur, scholarly but shrewd in judgment of men and issues. In the Persian Letters (1721), he had used the supposed correspondence of a Persian visitor to Paris to satirize both the church (under that “magician” the pope) and the society upon which it appeared to impose so fraudulently. His masterpiece, The Spirit of Laws, appeared in 22 editions within 18 months of publication in 1748. For this historically minded lawyer,  laws were not abstract rules but were necessary relationships derived from nature. Accepting completely Locke's sensationalist psychology, he pursued the line of the Sicilian Giambattista Vico, the innovative author of The New Science (1725), toward the idea that human values are the evolving product of society itself. Among social factors, he listed climate, religion, laws, the principles of government, the example of the past, and social practices and manners and concluded that from these a general spirit is formed. Montesquieu's concern with knowledge as a factor in shaping society is characteristic of the Enlightenment. Nor was he alone in his Anglophile tendency, though it did not prevent him from misinterpreting the English constitution as being based on the  separation of powers. The idea that moral freedom could be realized only in a regime whoselaws were enacted by an elected legislature, administered by a separate executive, and enforced by an independent judiciary was to be more influential in the New World than in the Old. His theories reflected a Newtonian view of the static equilibrium of forces and were influenced by his perception of the French government as increasingly arbitrary and centralist; they were conceived as much as a safeguard against despotism as an instrument of progress.

Montesquieu's political conservatism belonged to a world different from that of the younger generation of philosophes, for whom the main obstacle to progress was privilege; they put theirtrust in “the enlightened autocrat” and in his mandate for social engineering. They might fear, like  Claude Helvétius, that his theories would please the aristocracy. Helvétius—a financier, amateur philosopher, and author of the influential De l'esprit (1759; “On the Mind”)—advocated enlightened self-interest in a way that found an echo in physiocratic economic theory and argued that each individual, in seeking his own good, contributed to the general good. Laws, being man-made, should be changed so as to be more useful. The spirit of the Enlightenment is well conveyed by his suggestion that experimental ethics should be constructed in the same way as experimental physics. By contrast, Montesquieu, whose special concern was the sanctity of human law, saw the problem of rightconduct as one of adapting to circumstances. The function of reason was to bring about accord between human and natural law. While the objective nature of his inquiry encouraged those who trusted in the power of reason to solve human problems, it was left to those who saw the Enlightenment in more positive terms to work for change.

François-Marie Arouet, whose nom de plume  Voltaire was to become almost synonymous with the Enlightenment, was a pupil of the Jesuits at their celebrated college of Louis-le-Grand; his political education included 11 months in the Bastille. The contrast between the arbitrary injustice epitomized by the  lettrede cachet that brought about his imprisonment, without trial, forinsulting a nobleman and the free society he subsequently enjoyed in England was to inspire a life's commitment to the principles of reason, liberty, justice, and toleration. Voltaire at times played the role of adviser to princes (notably Frederick II) but learned that it was easier to criticize than to change institutions and laws. Like other philosophes living under a regime that denied political opportunity, he was no politician. Nor was he truly a philosopher in the way that Locke, Hume, or even Montesquieu can be so described. His importance was primarily as an advocate at the bar of public opinion. The case forthe reform of archaic laws and the war against superstition was presented with passion and authority, as notably in his Philosophical Dictionary. Candide (1759) shows his elegant command of language, whose potential for satire and argument had been demonstrated by Pascal's Provincial Letters of a century before. With astute judgment, he worked on the reader'ssensibilities. “The most useful books,” he wrote, “are those to which the readers themselves contribute half; they develop the idea of which the author has presented the seed.” He could lift an episode—the execution of Admiral Byng (1757) for failing to win a battle; of Jean Calas, seemingly, for being a Huguenot (1762); or of the Chevalier de la Barre, after torture, for alleged blasphemy (1766)—to the level at which it exemplified the injustices committed when man would not listen to the voice of reason or could not do so because of archaic laws. In Candide, hepresented the debate between the optimistic Dr. Pangloss and Martin, who believes in the reality of evil, in a way that highlights the issues and is as significant now as then.

Voltaire mounted his campaigns from a comfortable base, his large estate at Ferney. He was vain enough to relish his status as a literary lion and freedom's champion. He could be vindictive and was often impatient with differing views. In his reluctance to follow ideas through or consider their practical implications and in his patrician disregard for the material concerns of ordinary people, he epitomized faults with which the philosophes can be charged, the more because they were so censorious of others. Hewas generous chiefly in imaginative energy, in the indignation expressed in the celebrated war cry “Écrasez l'infâme” (literally “crush infamy,” signifying for Voltaire the intolerance of the church), and in the time he devoted to the causes of wronged individuals with whose plight he could identify. He had little to put in place of the religion he abused and offered no alternative vision. He did succeed notably in making people think about important questions—indeed, his questions were usually clearer than his answers.


The  Encyclopédie

The  Marquis de Condorcet, a mathematician and one of the more radical of his group, described his fellow philosophes as “a class of men less concerned with discovering truth than with propagating it.” That was the spirit which animated the great Encyclopédie, the most ambitious publishing enterprise of the century. It appeared in 17 volumes between 1751 and 1765, after checks and delays that would have disheartened anyone less committed than its publisher, André-François le Breton, or itschief editor and presiding genius,  Denis Diderot. Its publishing history is rich in incident and in what it reveals of the ambience of the Enlightenment. The critical point was reached in 1759, when French defeats made the authorities sensitive to anything that implied criticism of the regime. The publication of Helvétius' De l'esprit, together with doubts about the orthodoxy of another contributor, the Abbé de Prades, and concern about the growth of Freemasonry, convinced government ministers that they faced a plot to subvert authority. If they had been as united as the officials of the  church, the Encyclopédie would have been throttled. It was placed on the  Index of Forbidden Books, and a ban of excommunication was pronounced on any who should read it; but even Rome was equivocal. The knowledge that Pope Benedict XIV was privately sympathetic lessened the impact of the ban;  Malesherbes, from 1750 to 1763 director of the Librairie, whose sanction was required for publication, eased the passage of volumes he was supposed to censor. Production continued, but without Rousseau, an early contributor, who became increasingly hostile to the encyclopaedists and their utilitarian philosophy.

Diderot's coeditor, the mathematician  Jean le Rond d'Alembert, had, in his preface, presented history as the record of progress through learning. The title page proclaimed the authors' intention to outline the present state of knowledge about the sciences, arts, and crafts. Among its contributors were craftsmenwho provided the details for the technical articles. Pervading all was Diderot's moral theme: through knowledge “our children, better instructed than we, may at the same time become more virtuous and happy.” Such utilitarianism, closely related to Locke's environmentalism, was one aspect of what d'Alembert called “the philosophic spirit.” If it had been only that, it would have been as useful as Ephraim Chambers' Cyclopaedia (1727), which it set out to emulate. Instead, it became the textbook for the thoughtful—predominantly officeholders, professionals, the bourgeoisie, and particularly the young, who might appreciate Diderot's idea of the Encyclopédie as the means by which to change the common way of thinking. In the cause, Diderot sustained imprisonment in the jail at Vincennes (1749) and had to endure the condemnation and burning of one of his books, Philosophic Thoughts (1746). There was nothing narrow about his secular mission. Pensées sur l'interprétation de la nature (1753) advanced the idea of nature as a creative process of which man was an integral part. But his greatest achievement was the Encyclopédie. Most of the important thinkers of the timecontributed to it. Differences were to be expected, but there was enough unanimity in principles to endow the new gospel of scientific empiricism with the authority that Scripture was losing. It was also to provide a unique source for reformers.  Catherine II of Russia wrote to the German critic Friedrich Melchior Grimm for suggestions as to a system of education for young people. Meanwhile, she said she would “flip through the Encyclopédie; I shall certainly find in it everything I should and should not do.”


Rousseau and his followers

Diderot prefigured the unconventional style that found its archetype in  Jean-Jacques Rousseau. In his novel of the 1760s, Rameau's Nephew, Diderot's eccentric hero persuades his bourgeois uncle, who professes virtue, to confess to actions so cynical as to be a complete reversal of accepted values. Rousseau was close to this stance when he ridiculed those who derived right action from right thinking. He understood the interests of the people, which the philosophes tended to neglect and which Thomas Paine considered in the Rights of Man (1791).If virtue were dependent on  culture and culture the prerogative of a privileged minority, what was the prospect for the rest: “We have physicians, geometricians, chemists, astronomers, poets, musicians and painters in plenty; but no longer a citizen among us.” Rousseau is thus of the Enlightenment yet against it, at least as represented by the mechanistic determinism of Condillac or the elitism of Diderot, who boasted that he wrote only for those to whom he could talk—i.e., for philosophers. Rousseau challenged the privileged republic of letters, its premises, and its principles. His Confessions depicted a well-intentioned man forced to become a rogue and outcast by the artificiality of society. His first essay, Discourse on the Arts and Sciences (1750), suggested the contradiction between the exterior world of appearances and the inner world of feeling. With his view of culture now went emphasis on the value of emotions. Seminal use of concepts—such as “citizen” to indicate the rights proper to a member of a free society—strengthened signals that could otherwise confuse as much as inspire.

Dealing with the basic relations of life, Rousseau introduced the prophetic note that was to sound through democratic rhetoric. The state of nature was a hypothesis rather than an ideal: man must seek to recover wholeness at a higher level of existence. Forthis to be possible he must have a new kind of education and humanity a new political constitution. Émile (1762) proposed an education to foster natural growth. His Social Contract (1762) was banned, and this lent glamour to proposals for a constitutionto enable the individual to develop without offending against theprinciple of social equality. The crucial question concerned legitimate authority. Rousseau rejected both natural law and force as its basis. He sought a form of association that would allow both security and the natural freedom in which “each man,giving himself to all, gives himself to nobody.” It is realized in the form of the  general will, expressed in laws to which all submit. More than the sum of individual wills, it is general in that it represents the public spirit seeking the common good, which Rousseau defined as liberty and equality, the latter because liberty cannot subsist without it. He advocated the total sovereignty of the state, a political formula which depended on the assumption that the state would be guided by the general will. Rousseau's good society was a democratic and egalitarian republic. Geneva, his birthplace, was to prove boundless in inspiration. Rousseau's influence may have been slight in his lifetime, though some were proud to be numbered among admirers. His eloquence touched men of sensibility on both sidesof the Atlantic.

The French writer Morelly in the Code de la nature (1755), attacked property as the parent of crime and proposed that every man should contribute according to ability and receive according to need. Two decades later, another radical abbé, Gabriel de Mably, started with equality as the law of nature and argued that the introduction of  property had destroyed the golden age of man. In England,  William Godwin, following Holbach in obeisance to reason, condemned not only property but even the state of marriage: according to Godwin, man freed from the ties of custom and authority could devote himself to thepursuit of universal benevolence. To the young poets William Wordsworth and Percy Bysshe Shelley it was a beguiling vision; those less radical might fear for social consequences, such as thedraftsmen of the  Declaration of Rights of 1789, who were carefulto proclaim the sacred right of property.  Thomas Jefferson made the rights of man the foundation of his political philosophy as well as of the U.S. Constitution, but he remained a slave owner. The idea of “de-natured” man was as potent for the unsettling of the ancien régime as loss of the sense of God had been for the generation of Luther and Ignatius. It struck home to the educated young who might identify with Rousseau's self-estrangement and read into the image of “man everywhere in chains” their own perception of the privilege that thwarted talent. Such were Maximilien Robespierre, the young lawyer of Arras; Aleksandr Radischev, who advocated the emancipation of Russian serfs, or the Germans who felt restricted in regimented, often minuscule states. Both the severe rationalism of  Kant and the idealism of Sturm und Drang found inspiration in Rousseau. Yet Kant's Critique of Pure Reason (1781) and the sentimental hero portrayed by  Goethe in his Sorrows of Young Werther (1774) mark the end of the Enlightenment. “It came upon us so gray, so cimmerian, so corpse-like that we could hardly endureits ghost,” wrote Goethe, speaking for the Romantic generation and pronouncing valediction.

In  France the Enlightenment touched  government circles only through individuals, such as Anne-Robert Turgot, a  physiocrat, finance minister (1774–76), and frustrated reformer. The physiocrats, taking their cue from such writers as François Quesnay, author of Tableau économique (1758), advocated the removal of artificial obstacles to the growth of the natural economic order of a free market for the produce of the land. Even Adam Smith, who wrote the Wealth of Nations (1776) with a capitalist economy in mind, could see his avowed disciple William Pitt move only cautiously in the direction of free trade. Though the visionary William Blake could be adduced to show that there was powerful resistance to the new industrial society, the physician and scientist Erasmus Darwin was—with his fellow luminaries of the Lunar Society, Josiah Wedgwood and Matthew Boulton—at the heart of the entrepreneurial culture: there was no deep divide separating the English philosophes, with their sanctification of private property and individual interests, from the values and programs of government. In dirigiste France, where there was no internal common market and much to inhibit private investment, physiocratic ideas were politically naive: the gap between theory and implementation only illustrates the way in which the Enlightenment undermined confidence in the regime. Operating in a political vacuum, the philosophes could only hope that they would, like Diderot with Catherine the Great, exercise such influence abroad as might fulfill their sense of mission. In both Germany and Italy, however, circumstances favoured emphasis on the practical reforms that appealed as much to the rulers as to their advisers.


The Aufklärung

In  Germany the Aufklärung found its highest expression in a science of government. one explanation lies in the importance of universities. There were nearly 50 by 1800 (24 founded since 1600); they were usually the product of a prince's need to have trained civil servants rather than of a patron's zeal for higher learning. Not all were as vigorous as Halle (1694) or Göttingen (1737), but others, such as Vienna in the last quarter of the 18thcentury, were inspired to emulate them. In general, the universities dominated intellectual and cultural life. Rulers valued them, and their teachers were influential, because they served the state by educating those who would serve. Leading academic figures held posts, enabling them to advise the government: the political economist Joseph von Sonnenfels was an adviser to the Habsburgs on the serf question.  Lutheranism was another important factor in the evolution of the attitude to authority that makes the German Enlightenment so markedly different from the French. In the 18th century it was further influenced by  Pietism, which was essentially a devotional movement though imbued with a reforming spirit. Nor was the earnest religious spirit confined to the Protestant confessions. In Maria Theresa's Austria, Jansenism, which penetrated Viennese circles from Austrian Flanders, was as important in influencing reforms in church and education as it was in sharpening disputes with the Papacy. But there was nothing comparable, even in the Catholic south and Rhineland, to the revolt of westernintellectuals against traditional dogma. Amid all his speculations, Leibniz, who more than any other influenced German thought, had held to the idea of a personal God not subject to the limitations of a material universe. It was devotion, not indifference, that made him, with Bossuet, seek ground for Christian reunion.

Leibniz's disciple,  Christian Wolff, a leading figure of the Aufklärung, was opposed to the Pietists, who secured his expulsion from Halle in 1723. Yet, though he believed that reason and revelation could be reconciled, he shared with the Pietists fundamental Christian tenets. In Halle there emerged a synthesis of Wolffism and Pietism, a scientific theology that was progressive but orthodox. Pervading all was respect for the ruler, reflecting the acceptance of the cuius regio, eius religio principle; it reduced the scope for internal conflicts, which elsewhere bred doubts about authority. In translating conservative attitudes into political doctrines, the contribution ofthe lawyers and the nature of the law they taught were crucial. In place of the moral vacuum in which the single reality was the power of the individual ruler, there had come into being a body oflaw, articulated preeminently by  Hugo Grotius in on the Law of War and Peace. It was grounded not only in proven principles of private law but also in the Christian spirit, though it was strengthened by Grotius' separation of  natural law from its religious aspects. As expounded by Wolff and the historiographerSamuel Pufendorf, natural law endorsed absolutism. They did notwholly neglect civil rights, they advocated religious toleration, and they opposed torture, but, living in a world far removed fromthat of Locke or Montesquieu, they saw no need to stipulate constitutional safeguards. Wolff declared that “he who exercises the civil power has the right to establish everything that appearsto him to serve the public good.” Such a sovereign, comprising legislative, executive, and judicial functions, was also, as defined in Wolff's Rational Thoughts on the Social Life of Mankind (1756),a positive force, benevolent: he was Luther's “godly prince” in 18th-century dress, serving his people's needs. Cameralwissenschaft—the science and practice of administration—would serve the ruler by increasing the revenue and also improve the lot of the people.

Envisaging progress under the sovereign who created the schools, hospitals, and orphanages and provided officials to run them, Wolff was only one among numerous writers who contributed to the ideal of benevolent bureaucratic absolutism, or Wohlfahrstaat. Though also influenced by the local school of cameralists and 17th-century writers such as Philippe Wilhelm von Hörnigk and Johann Joachim Becher, the emperor  Joseph II, having the largest area to rule and the most earnest commitment to its principles, came to exemplify the Aufklärung. By his time, however, there was a growing reaction against the soulless rationality of the natural lawyers. With the exception of the Prussian critic Johann Gottfried Herder, whose ideal Volk-state would have a republican constitution, political thoughtwas unaffected by the emphasis of the literary giants of Romanticism on freedom and spontaneity. His contemporary  Kant, an anticameralist, believed in a degree of popular participation but would not allow even the theoretical right of revolution. In Was ist Aufklärung? Kant drew a vital distinction between the public and private use of one's reason. With Frederick the Great in mind, he advanced the paradox that can be taken as a text for the Enlightenment as well as for German history. The ruler with a well-disciplined and large army could provide more liberty than a republic.
