Hortatory Address to the Greeks

It is therefore necessary, ye Greeks, that you contemplate the things that are to be, and consider the judgment which is predicted by all, not only by the godly, but also by those who are irreligious, that ye do not without investigation commit yourselves to the error of your fathers, nor suppose that if they themselves have been in error, and have transmitted it to you, that this which they have taught you is true; but looking to the danger of so terrible a mistake, inquire and investigate carefully into those things which are, as you say, spoken of even by your own teachers. For even unwillingly they were on your account forced to say many things by the Divine regard for mankind, especially those of them who were in Egypt, and profited by the godliness of Moses and his ancestry. For I think that some of you, when you read even carelessly the history of Diodorus, and of those others who wrote of these things, cannot fail to see that both Orpheus, and Homer, and Solon, who wrote the laws of the Athenians, and Pythagoras, and Plato, and some others, when they had been in Egypt, and had taken advantage of the history of Moses, afterwards published doctrines concerning the gods quite contrary to those which formerly they had erroneously promulgated.
