In treating of the subject proposed, I have sometimes found myself obliged to differ from persons, for whose learning and judgment I have a great regard. And though I am not conscious to myself of having made any wilful misrepresentations of things, yet it is very probable that, in the course of so long a work, I have committed mistakes, which will need the indulgence of the reader.
As a book of this kind must unavoidably contain a great number of quotations, I have not thought it necessary in every instance to give the words in the original language, though I have frequently done so; but have, to the best of my ability, always given a faithful account of their sense. Great care has been taken to make the references to the quotations particular and exact, that any man who pleases may the more easily have it in his power to examine and compare them.
After I had brought the following work near to a conclusion, I met with a book written by the late learned Dr. Archibald Campbell, Professor of Divinity and Ecclesiastical History in the University of St. Andrews, which I had not seen before, entitled, "The Necessity of Revelation: or, an Enquiry into the ex"tent of Human Powers with respect to Matters of Religion; "especially those two fundamental articles, the Being of God, "and the Immortality of the Soul." Published in 1739. As the design of this treatise seems in some measure to coincide with what I had in view, I read it over with great care, and must do him the justice to say that he has treated his subject with great learning and diligence. But the method he makes use of is so different from that which I have pursued, that the one does not interfere with the other; nor has it occasioned any alteration in the plan which I had formed. I have, however, in several places, added marginal notes referring to the Doctor's book, either where I thought it contained a fuller illustration of what I have more briefly hinted at, or where, as sometimes has been the case, I happened to differ from that learned writer.
Not to detain the reader any longer, the plan of the following work is briefly this:
That there was an original revelation communicated to mankind in the earliest ages, for leading them to the knowledge of God and religion, some vestiges of which continued long among
