A blow on the head, or fracture of the cranium, as also palsies and many other casualties that await our sensorium, retard, and in some cases wholly prevent the exercise of reason for a longer or shorter period; and sometimes through the stage of human life; but in such instances as these, reason is not depraved, but ceases in a greater or less degree, or perhaps wholly ceases its rational exertions or operations; by reason of the breaches or disorders of the organs of sense, but in such instances, wherein the organs become rectified, and the senses recover their usefulness, the exercise of reason returns, free from any blemish or depravity. For the cessation of the exercise of reason, by no means depraves it. From what has been argued on this subject, in this and the preceding chapters, it appears that reason is not and cannot be depraved, but that it bears a likeness to divine reason, is of the same kind, and in its own nature as uniform as truth, which is the test of it; though in the divine essence, it is eternal and infinite, but in man it is eternal only as it respects their immortality, and finite as it respects capaciousness. Such people as can be prevailed upon to believe, that their reason is depraved, may easily be led by the nose, and duped into superstition at the pleasure of those in whom they confide, and there remain from generation to generation: for when they throw by the law of reason _the only one_ which God gave them to direct them in their speculations and duty, they are exposed to ignorant or insidious teachers, and also to their own irregular passions, and to the folly and enthusiasm of those about them, which nothing but reason can prevent or restrain: nor is it a rational supposition that the commonality of mankind would ever have mistrusted that their reason was depraved, had they not been told so, and it is whispered about, that the first insinuation of it was from the Priests; (though the Armenian Clergymen in the circle of my acquaintance have exploded the doctrine.) Should we admit the depravity of reason, it would equally affect the priesthood, or any other teachers of that doctrine, with the rest of mankind; but for depraved creatures to receive and give credit to a depraved doctrine, started and taught by depraved creatures, is the greatest weakness and folly imaginable, and comes nearer a proof of the doctrine of total depravity, than any arguments which have been advanced in support of it.
