Now those are called philosophers, among us, who love Wisdom, the Creator and Teacher of all things, that is, the knowledge of the Son of God; and among the Greeks, those who undertake arguments on virtue. Philosophy, then, consists of such dogmas found in each sect (I mean those of philosophy) as cannot be impugned, with a corresponding life, collected into one selection; and these, stolen from the Barbarian God-given grace, have been adorned by Greek speech. For some they have borrowed, and others they have misunderstood. And in the case of others, what they have spoken, in consequence of being moved, they have not yet perfectly worked out; and others by human conjecture and reasoning, in which also they stumble. And they think that they have hit the truth perfectly; but as we understand them, only partially. They know, then, nothing more than this world. And it is just like geometry, which treats of measures and magnitudes and forms, by delineation on plain surfaces; and just as painting appears to take in the whole field of view in the scenes represented. But it gives a false description of the view, according to the rules of the art, employing the signs that result from the incidence of the lines of vision. By this means, the higher and lower points in the view, and those between, are preserved; and some objects seem to appear in the foreground, and others in the background, and others to appear in some other way, on the smooth and level surface. So also the philosophers copy the truth, after the manner of painting. And always in the case of each one of them, their self-love is the cause of all their mistakes. Wherefore one ought not, in the desire for the glory that terminates in men, to be animated by self-love; but loving God, to become really holy with wisdom. If, then, one treats what is particular as universal, and regards that, which serves, as the Lord, he misses the truth, not understanding what was spoken by David by way of confession: “I have eaten earth [ashes] like bread.”[996] Now, self-love and self-conceit are, in his view, earth and error. But if so, science and knowledge are derived from instruction. And if there is instruction, you must seek for the master. Cleanthes claims Zeno, and Metrodorus Epicurus, and Theophrastus Aristotle, and Plato Socrates. But if I come to Pythagoras, and Pherecydes, and Thales, and the first wise men, I come to a stand in my search for their teacher. Should you say the Egyptians, the Indians, the Babylonians, and the Magi themselves, I will not stop from asking their teacher. And I lead you up to the first generation of men; and from that point I begin to investigate Who is their teacher. No one of men; for they had not yet learned. Nor yet any of the angels: for in the way that angels, in virtue of being angels, speak, men do not hear; nor, as we have ears, have they a tongue to correspond; nor would any one attribute to the angels organs of speech,
