It is with great pleasure I can inform you, that Priestley finished the comparative view of the doctrines of the philosophers of antiquity, and of Jesus, before his death; and that it was printed soon after. And, with still greater pleasure, that I can have a copy of his work forwarded from Philadelphia, by a correspondent there, and presented for your acceptance, by the same mail which carries you this, or very soon after. The branch of the work which the title announces, is executed with learning and candor, as was everything Priestley wrote, but perhaps a little hastily; for he felt himself pressed by the hand of death. The Abbé Batteux had, in fact laid the foundation of this part in his Causes Premieres, with which he has given us the originals of Ocellus and Timæus, who first committed the doctrines of Pythagoras to writing, and Enfield, to whom the Doctor refers, had done it more copiously. But he has omitted the important branch, which, in your letter of August the 9th, you say you have never seen executed, a comparison of the morality of the Old Testament with that of the New. And yet, no two things were ever more unlike. I ought not to have asked him to give it. He dared not. He would have been eaten alive by his intolerant brethren, the Cannibal priests. And yet, this was really the most interesting branch of the work. Very soon after my letter to Doctor Priestley, the subject being still in my mind, I had leisure during an abstraction from business for a day or two, while on the road, to think a little more on it, and to sketch more fully than I had done to him, a syllabus of the matter which I thought should enter into the work. I wrote it to Doctor Rush, and there ended all my labor on the subject; himself and Doctor Priestley being the only two depositories of my secret. The fate of my letter to Priestley, after his death, was a warning to me on that of Doctor Rush; and at my request, his family were so kind as to quiet me by returning my original letter and syllabus. By this, you will be sensible how much interest I take in keeping myself clear of religious disputes before the public, and especially of seeing my syllabus disembowelled by the Aruspices of the modern Paganism. Yet I enclose it _to you_ with entire confidence, free to be perused by yourself and Mrs. Adams, but by no one else, and to be returned to me. You are right in supposing, in one of yours, that I had not read much of Priestley's Predestination, his no-soul system, or his controversy with Horsley. But I have read his Corruptions of Christianity, and Early Opinions of Jesus, over and over again; and I rest on them, and on Middleton's writings, especially his letters from Rome, and to Waterland, as the basis of my own faith. These writings have never been answered, nor can be answered by quoting historical proofs, as they have done. For these facts, therefore, I cling to their learning, so much superior to my own.
