DEAR SIR,--I have more to say on religion. For more than sixty years I have been attentive to this great subject. Controversies between Calvinists and Armenians, Trinitarians and Unitarians, Deists and Christians, Atheists and both, have attracted my attention, whenever the singular life I have led would admit, to all these questions. The history of this little village of Quincy, if it were worth recording, would explain to you how this happened. I think I can now say I have read away bigotry, if not enthusiasm. What does Priestley mean by an unbeliever, when he applies it to you? How much did he "unbelieve" himself? Gibbon had him right, when he determined his creed "scanty." We are to understand, no doubt, that he believed the resurrection of Jesus; some of his miracles; his inspiration, but in what degree? He did not believe in the inspiration of the writings that contain his history, yet he believed in the Apocalyptic beast, and he believed as much as he pleased in the writings of Daniel and John. This great, excellent, and extraordinary man, whom I sincerely loved, esteemed, and respected, was really a phenomenon; a comet in the system, like Voltaire, Bolingbroke, and Hume. Had Bolingbroke or Voltaire taken him in hand, what would they have made of him and his creed. I do not believe you have read much of Priestley's "corruptions of Christianity," his history of early opinions of Jesus Christ, his predestination, his no-soul system, or his controversy with Horsley. I have been a diligent student for many years in books whose titles you have never seen. In Priestley's and Linsay's writings; in Farmer, in Cappe, in Tucker's or Edwards searches; Light of Nature pursued; in Edwards and Hopkins, and lately in Ezra Styles Ely; his reverend and learned panegyrists, and his elegant and spirited opponents. I am not wholly uninformed of the controversies in Germany, and the learned researches of universities and professors, in which the sanctity of the Bible and the inspiration of its authors are taken for granted, or waived, or admitted, or not denied. I have also read Condorcet's Progress of the Human Mind.
