the not doing so and so, would be inconsistent with the former, or repugnant to the latter. I content myself to contemplate what I am sure he has done, and to adore him for it in humble silence. I can demonstrate, that every cavil, which has been brought against the great system of the world, physical and moral, from the days of Democritus and Epicurus to this day, is absurd; but I dare not pronounce why things are made as they are, state the ends of infinite wisdom, and show the proportion of the means.

Whether I can be of use to him even in this part, I know not; for, having fixed my opinion long ago concerning all ancient history and chronology, by a careful examination into the first principles of them, I have ever since laid that study totally aside. I confess, in the letter I writ lately to the doctor, notwithstanding my great respect for sir John Marsham, that his authority is often precarious, because he leans often on other authorities, which are so. But to you I will confess a little more: I think, nay, I know, that there is no possibility of making any system of that kind, without doing the same thing; and that the defect is in the subject, not in the writer.
