It remains then unanswerable according to the previous argument, that religion and the worship of God according to the promptings of natural light, is consistent with truth and justice; but if any one wishes to establish any new principles in religion, either new or displeasing, and that by the authority of invisible powers, it will evidently be necessary for him to show his power of reforming, unless he wishes to be considered by all an impostor. Since, not under the conclusions of natural religion, nor under the authority of special revelation, he offers opposition to the ideas of all. Moreover he should be so upright in life and character that the people may believe him worthy of being associated with so high and holy a power, who does not approve of anything impure. Nor can merely his own confession, nor the holiness of a past life, nor any miracles--that is extraordinary deeds--prove this; for this is common rather among the skillful and the deceivers of men, lying hypocrites who pursue their own advantage and glory in this way. For it is not worth considering that some reached such a degree of madness that they voluntarily sought death, in order that it might be supposed that they despised and conquered everything, like different ones among the ancient philosophers. Nor is it to be supposed that they were upheld by special divine powers in that which they did because of foolish fancies and fond hopes of mountains of gold, rising from a defective judgment. For they did not give the matter the proper consideration, nor did the real teachers, for in order that you may come to a fair decision about them, I have said not only is their own testimony not sufficient, but in order to reach the truth of the matter, they must be compared with one another; and other witnesses with them, and then their acquaintances and friends, and then strangers, then friends and enemies; and then after the testimony is all gathered in, that of each teacher concerning himself, and then that of others must be compared. And if we do not know the witnesses, we must consult the witnesses of the witnesses, and so on; besides instituting an investigation as to your powers of distinguishing from the true and the false involved in such or other circumstances. Especially in similar ones, inquiring, moreover, whence you desired data to learn the truth, for this purpose comparing the judgment of others, as to what they infer from such an investigation or from the testimony of witnesses. And from these data it will be permissible to infer whether he who makes this claim, is a true messenger of the revelation of divine will and whether his teachings should be gradually adopted. But at this point we must be very careful not to get into a circle. Whenever the nature of important religions may be such that one supplants another, as that of Moses, Paganism, that of Mahomet, Christianity,--the later one may not always nor in
