Introduction
THE preceding Book, which is the tenth of the Evangelical Preparation,was intended to prove by no statements of my own, but by external testimonies, that as the Greeks had contributed no additional wisdom from their own resources, but only their force and elegance of language, and had borrowed all their philosophy from Barbarians, it was not improbable that they were also not unacquainted with the Hebrew Oracles, but had in part seized upon them also; seeing that they did not keep their hands clean from theft even of the literary efforts of their own countrymen. For, as I said, it was not my statement but their own that proved them to be thieves.
Moreover in the same Book we learned by the comparison of dates that they were very young in age as well as in wisdom, and fell very far short of the ancient literature of the Hebrews.
Such were the contents of the preceding Book: but in this present one we hasten on at once to pay as it were a debt, I mean the promise which was given, and to exhibit the agreement of the Greek philosophers with the Hebrew Oracles in some if not in all their doctrinal theories. Dismissing therefore those of whom it is superfluous to speak, we call up the leader of the whole band, deeming it right to adopt as umpire of the question Plato alone as equivalent to all: since it is likely that as he surpassed all in reputation he will be sufficient by himself for the settlement of our question.
But if at any point it should be necessary, for the sake of giving clearness to his thought, I shall also make use of the testimony of those who have studied his philosophy, and shall set forth their own words for the settlement of the question before us.
Let me, however, make this reservation, that not every matter has been successfully stated by the master, although he has expressed most things in accordance with truth. And this very point also we shall prove at the proper season, not in order to disparage him, but in defence of the reason for which we confess that we have welcomed the Barbarian philosophy in preference to the Greek.
