Yet among the great men of letters in France contemporary with Voltaire, the most part went immeasurably farther than he, and went in a different direction withal, for they denied the reality of Religion. Few of them, indeed, believed in the existence of God, or would have had anything to do with building a house of worship. It is related of David Hume that when dining once in a party of eighteen at the house of Baron d'Holbach, he expressed a doubt as to whether any person could anywhere be found to avow himself dogmatically an atheist. "Indeed, my dear sir," quoth the host, "you are this moment sitting at table with seventeen such persons." Among that group of philosophers were men of great intelligence and lofty purpose, such as D'Alembert, Diderot, Helvétius, Condorcet, Buffon, men with more of the real spirit of Christianity in their natures than could be found in half the churches of Christendom. The roots of their atheism were emotional rather than philosophical. It was part of the generous but rash and superficial impatience with which they disowned all connection whatever with a Church that had become subservient to so much that was bad. Their atheism was one of the fruits of the vicious policy which had suppressed Huguenotism in France; it was an early instance of what has since been often observed, that materialism and atheism are much more apt to flourish in Romanist than in Protestant countries. The form of religion which is already to some extent purified and rationalized awakens no such violent revulsion in free-thinking minds as the form that is more heavily encumbered with remnants of obsolete primitive thought. Moreover, the rationalizing religion of Protestant countries is commonly found in alliance with political freedom. In France under the Old Régime, the Catholic religion was stigmatized as an ally of despotism, as well as a congeries of absurd doctrines and ceremonies. The best minds felt their common sense shocked by it no less than their reason. No very deep thinking was done on the subject; their treatment of it was in general extremely shallow.
