The idea of progress[i-15] was popularized (if not born) in the eighteenth century. It has been recently shown that not only the results of scientific investigations but also Anglican defenses of revealed religion served to accelerate a belief in progress. In answer to the atheists and deists who indicted revealed religion because revelation was given so late in the growth of the human family and hence was not eternal, universal, and immutable, the Anglican apologists were forced into the position of asserting that man enjoyed a progressive ascent, that the religious education of mankind is like that of the individual. If, as the deists charged, Christ appeared rather belatedly, the apologists countered that he was sent only when the race was prepared to profit by his coming. God's revelations thus were adjusted to progressive needs and capacities.[i-16] Carl Becker has suggestively dissected the Enlightenment in a series of antitheses between its credulity and its skepticism. If the eighteenth-century philosopher renounced Eden, he discovered Arcadia in distant isles and America. Rejecting the authority of the Bible and church, he accepted the authority of "nature," natural law, and reason. Although scorning metaphysics, he desired to be considered philosophical. If he denied miracles, he yet had a fond faith in the perfectibility of the species.[i-17] Even as Voltaire had his liberal tendencies stoutly reinforced by contact with English rationalism and deism,[i-18] so were the other French _philosophes_, united in their common hatred of the Roman Catholic church, also united in their indebtedness to exponents of English liberalism, dominated by Locke and Newton. If, as Madame de Lambert wrote in 1715, Bayle more than others of his age shook "the Yoke of authority and opinion," English free thought powerfully reinforced the native French revolt against authoritarianism. After 1730 English was the model for French thought.[i-19] Nearly all of Locke's works had been translated in France before 1700. Voltaire's affinity for the English mind has already been touched on. D'Alembert comments, "When we measure the interval between a Scotus and a Newton, or rather between the works of Scotus and those of Newton, we must cry out with Terence, _Homo homini quid præstat_."[i-20]
