““I have observed, indeed, generally, that while in protestant countries the defections from the Platonic Christianity of the priests is to Deism, in catholic countries they are to Atheism. Diderot , D'Alembert , D’Holbach , Condorcet , are known to have been among the most virtuous of men. Their virtue, then, must have had some other foundation than the love of God. [ Letter to Thomas Law, 13 June 1814 ]””
