The principal writers of the English school were Lord Herbert of Cherbury (1581-1648), whose works tended to call in question the existence of a supernatural religion; John Hobbs (1588-1679) the apostle of absolute rule, who saw in religion only a means of keeping the people in subjection; John Locke (1632-1704), nominally a Christian himself, whose philosophy of Empiricism and Sensualism barred the way effectively against belief in a supernatural religion;Charles Blount (1630-93), who like Flavius Philostratus sought to discredit Christianity by setting up Apollonius of Tyana as a rival of Christ; Collins, the patron of free-thinkers (1676-1729); John Toland (1670-1722), who although originally a believer in Christian revelation tended more and more towards Pantheism; and Tyndal (1656-1733), who changed from Protestantism to Catholicism and finally from Christianity to Rationalism. In England Deism and Naturalism secured a strong foot-hold amongst the better classes, but the deeply religious temperament of the English people and their strong conservatism saved the nation from falling under the influence of such ideas.
In France the religious wars between the Catholics and Calvinists, the controversies that were waged by the Jansenists and Gallicans, the extravagances of the /Convulsionnaires/, the flagrant immorality of the court during the rule of the Duke of Orleans and of Louis XV., and the enslavement of the Church, leading as it did to a decline of zeal and learning amongst the higher clergy, tended inevitably to foster religious indifference amongst the masses. In the higher circles of society Rationalism was looked upon as a sign of good breeding, while those who held fast by their dogmatic beliefs were regarded as vulgar and unprogressive. Leading society ladies such as Ninon de Lenclos (1615-1706) gathered around them groups of learned admirers, who under the guise of zeal for the triumph of literary and artistic ideals sought to popularise everything that was obscene and irreligious.
Amongst some of the principal writers who contributed largely to the success of the anti-Christian campaign in France might be mentioned Peter Bayle (1647-1706), whose /Dictionnaire historique et critique/became the leading source of information for those who were in search of arguments against Christianity; John Baptist Rousseau (1671-1741), whose life was in complete harmony with the filthiness to which he gave expression in his works; Bernard le Boivier de Fontenelle (1657-1757), who though never an open enemy of the Catholic Church contributed not a little by his works to prepare the way for the men of the Enclyclopaedia; Montesquieu (1689-1755), whose satirical books on both Church and State were read with pleasure not only in France but in nearly every country of Europe; D'Alembert (1717-83) and Diderot (1713-84), the two men mainly responsible for the /Encyclopedie/; Helvetius (1715-1771), and the Baron d'Holbach, who sought to popularise the irreligious views then current among the nobility by spreading the rationalist literature throughout the mass of the poorer classes in Paris.
But the two writers whose works did most to undermine revealed religion in France were Francois Marie Arouet, better known as Voltaire (1694-1778), and Jean-Jacques Rousseau (1712-1778). The former of these was born at Paris, received his early education from the Jesuits, and was introduced while still a youth to the salon of Ninon de Lenclos, frequented at this time by the principal literary opponents of religion and morality. His earliest excursions into literature marked him out immediately as a dangerous adversary of the Christian religion. He journeyed in England where he was in close touch with the Deist school of thought, in Germany where he was a welcome guest at the court of Frederick II. of Prussia, and settled finally at Ferney in Switzerland close to the French frontiers.
Towards the end of his life (1778) he returned to Paris where he received a popular ovation. Poets, philosophers, actresses, and academicians vied with one another in doing honour to a man who had vowed to crush /L'Infame/, as he termed Christianity, and whose writings had done so much to accomplish that result in the land of his birth. The reception given to Voltaire in Paris affords the most striking proof of the religious and moral corruption of all classes in France at this period. Jean-Jacques Rousseau was born at Geneva and reared as a Calvinist. Later on he embraced the Catholic religion, from which he relapsed once more into Calvinism, if indeed in his later years he was troubled by any dogmatic beliefs. His private life was in perfect harmony with the moral tone of most of his works. He had neither the wit nor the literary genius of Voltaire, but in many respects his works, especially /Le Contrat Social/, exercised a greater influence on the France of his own time and on Europe generally since that time than any other writings of the eighteenth century. His greatest works were /La Nouvelle Heloise/ (1759), a novel depicting the most dangerous of human passions; /Emile/, a philosophical romance dealing with educational ideas and tending directly towards Deism, and /Le Contrat Social/, in which he maintained that all power comes from the people, and may be recalled if those to whom it has been entrusted abuse it. The /Confessions/which tell the story of his shameless life were not published until after his death.
