“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]”

“If, therefore, from the settlement of the Saxons, to the introduction of Christianity among them, that system of religion could not be a part of the common law, because they were not yet Christians; and if, having their laws from that period to the close of the common law, we are able to find among them no such act of adoption; we may safely affirm (though contradicted by all the judges and writers on earth) that Christianity neither is, nor ever was, a part of the common law.['Whether Christianity is Part of the Common Law?', letter to Dr. Thomas Cooper, from Monticello, February 10, 1814]”

Yet so strong is his constitution, that he may endure for centuries before he expires.{Letter to Thomas Jefferson, July 16 1814}”

“I received your letter of June 10th. I have never talked to a Jesuit priest in my life and I am astonished by the audacity to tell such lies about me. From the viewpoint of a Jesuit priest I am, of course, and have always been an atheist.”

“I am glad," he said, "that I do not dwell in your country among such savage peoples. Here, in Caspak, men fight with men when they meet - men of different races - but their weapons are first for the slaying of beasts in the chase and defense. We do not fashion weapons solely for the killing of man as do your peoples. Your country must indeed be a savage country, from which you are fortunate to have escaped to the peace and security of Caspak.”
