"I do not enter so far into the province of the logicians as to take notice of the difference there is between the analytic and synthetic methods of coming at truth, or proving it;—whether it is better to begin the disquisition from the subject, or from the attribute. If by the use of proper media anything can be showed to be, or not to be, I care not from what term the demonstration or argument takes its rise. Either way propositions may beget their like, and more truth be brought into the world."—Religion of Nature Delineated, p. 45 (a.d. 1722).
