Between these, there is still another way of knowing any one, namely through his own writings, which may be called one's own testimony concerning himself. And concerning Christ, there is no such testimony; concerning Moses, it is doubtful whether there is; concerning Mahomet, there is the Koran. The testimony of others is of two classes--that of friends and that of enemies. Between these extremes there is no third class, according to the saying, "who is not with me is against me." Mahomet in his writings assumes and attributes to himself the same divine qualities as did Moses and another. Moreover the friends of Mahomet and members of his sect wrote the same things concerning him as did the members of the sects of the others concerning their masters, and the enemies of the others wrote just as disparagingly of them as their friends did of Mahomet. As for the rest, the testimony of any one concerning himself is too unreliable to inspire implicit confidence, and is of no consequence except, perchance, to perplex a thoughtless hearer. The assertions of friends, who doubtless unanimously repeat the sayings of their masters, are of the same nature. Nor should the enemies of any one be heeded on account of their prejudices. But as it is, in spite of these facts, it is for such trivial reasons, which are confirmed only by the master's own boasts, the assertions of friends, or the calumnies of enemies, that every follower of any one of the three assumes that the claims of his enemy are based wholly on imposture, while the teachings of his master are founded wholly on truth. Nevertheless Mahomet is undoubtedly considered an impostor among us; but why? Not from his own testimony or that of his friends but from that of his enemies. Then, on the contrary, among the Mahometans he is considered a most holy prophet; but why? From his own testimony, but especially from that of his friends. Whoever considers Moses an impostor or a holy teacher employs the same method of reasoning. And there is equal reason in the case of Mahomet as in the case of the others, either for charging him with imposture or for answering that charge, although, nevertheless, the former are considered holy, while he is considered a scoundrel, contrary to all the demands of justice. To put it in the scholastic manner, then, the following conclusions are most firmly established: Whenever there is the same reason as in the case of Mahomet for charging any person with imposture or for answering that charge, they should be placed in the same category. And for example, in the case of Moses, there is the same reason, therefore justice should be demanded just as in the case of Mahomet, nor should he be considered an impostor. PROOF OF MINOR PREMISE.
