I am aware that Descartes, and most of the schools which have believed in the _plenum_, and the infinity of matter, have nevertheless admitted a God; but this is only because men scarcely ever reason or act upon their principles. Had men reasoned, consequently, Epicurus and his apostle Lucretius must have been the most religious assertors of the Providence which they combated; for when they admitted the void and the termination of matter, a truth of which they had only an imperfect glimpse, it necessarily followed that matter was the being of necessity, existing by itself, since it was not indefinite. They had, therefore, in their own philosophy, and in their own despite, a demonstration that there is a Supreme Being, necessary, infinite, the fabricator of the universe. Newton's philosophy, which admits and proves the void and finite matter, also demonstratively proves the existence of a God. Thus I regard true philosophers as the apostles of the Divinity. Each class of men requires its particular ones; a parish catechist tells children that there is a God, but Newton proves it to the wise. In London, under Charles II. after Cromwell's wars, as at Paris under Henry IV. after the war of the Guises, people took great pride in being atheists; having passed from the excess of cruelty to that of pleasure, and corrupted their minds successively by war and by voluptuousness, they reasoned very indifferently. Since then the more nature has been studied the better its Author has been known. One thing I will venture to believe, which is, that of all religions, theism is the most widely spread in the world. It is the prevailing religion of China; it is that of the wise among the Mahometans; and, among Christian philosophers, eight out of ten are of the same opinion. It has penetrated even into the schools of theology, into the cloisters, into the conclave; it is a sort of sect without association, without worship, without ceremonies, without disputes, and without zeal, spread through the world without having been preached. Theism, like Judaism, is to be found amidst all religions; but it is singular that the latter, which is the extreme of superstition, abhorred by the people and contemned by the wise, is everywhere tolerated for money; while the former, which is the opposite of superstition, unknown to the people, and embraced by philosophers alone, is publicly exercised nowhere but in China. There is no country in Europe where there are more theists than in England. Some persons ask whether they have a religion or not. There are two sorts of theists. The one sort think that God made the world without giving man rules for good and evil. It is clear that these should have no other name than that of philosophers.
