It may be, that some who embrace the doctrine of the depravity of human reason, will not admit that it is wholly and totally depraved, but that it is in a great measure marred or spoiled. But the foregoing arguments are equally applicable to a supposed depravity in parts, as in the whole; for in order to judge whether reason be depraved in part or not, it would be requisite to have an understanding of what reason may be supposed to have been, previous to its premised depravity; and to have such a knowledge of it, would be the same as to exercise and enjoy it in its lustre and purity, which would preclude the notion of a depravity in part, as well as in the whole; for it would be utterly impossible for us to judge of reason undepraved and depraved, but by comparing them together. But for depraved reason to make such a comparison, is contradictory and impossible; so that, if our reason had been depraved, we could not have had any conception of it any more than a beast. Men of small faculties in reasoning cannot comprehend the extensive reasonings of their superiors, how then can a supposed depraved reason comprehend that reason which is uncorrupted and pure? To suppose that it could, is the same as to suppose that depraved and undepraved reason is alike, and if so, there needs no further dispute about it. There is a manifest contradiction in applying the term _depraved_ to that of reason, the ideas contained in their respective definitions will not admit of their association together, as the terms convey heterogeneous ideas; for reason spoiled, marred, or robbed of its perfection, ceaseth to be rational, and should not be called reason; inasmuch as it is premised to be depraved, or degenerated from a rational nature; and in consequence of the deprivation of its nature, should also be deprived of its name, and called subterfuge, or some such like name, which might better define its real character. Those who invalidate reason, ought seriously to consider, "_whether they argue against reason, with or without reason; if with reason, then they establish the principle, that they are laboring to dethrone:_" but if they argue without reason, (which, in order to be consistent with themselves, they must do,) they are out of the reach of rational conviction, nor do they deserve a rational argument.
