(1) If, however, it be necessary, dismissing these particulars, to speak what appears to me to be the truth, you do not rightly infer “ that a knowledge of this mathematical science cannot be obtained, because there is much dissonance concerning it, or because Chæremon, or some other, has written against it .” For if this reason were admitted, all things will be incomprehensible. For all sciences have ten thousand controvertists, and the doubts with which they are attended are innumerable. As, therefore, we are accustomed to say in opposition to the contentious, that contraries in things that are true are naturally discordant, and that it is not falsities alone that are hostile to each other; thus, also, we say respecting this mathematical science, that it is indeed true; but that those who wander from the scope of it, being ignorant of the truth, contradict it. This, however happens not in this science alone, but likewise in all the sciences, which are imparted by the Gods to men.

(1) I, at any rate, am not conscious, when speaking in reply to Greeks or others, of fancying to assist good men, in case they should be able to know and speak the very truth, as it really is in itself. For, when this is correctly demonstrated in its essential nature, according to a law of truth, and has been established without flaw, every thing which is otherwise, and simulates the truth, will be convicted of being other than the reality, and dissimilar, and that which is seeming rather than real. It is superfluous then, that the expounder of truth should contend with these or those. For each affirms himself to have the royal coin, and perchance has some deceptive image of a certain portion of the true. And, if you refute this, first the one, and then the other, will contend concerning the same. But, when the true statement itself has been correctly laid down, and has remained unrefuted by all the rest, every thing which is not so in every respect is cast down of itself, by the impregnable stability of the really true. Having then as I think well understood this, I have not been over zealous to speak in reply to Greeks or to others; but it is sufficient for me (and may God grant this), first to know about truth, then, having known, to speak as it is fitting to speak.

(1) In order, therefore, that from an abundance of arguments we may contend against the objection which is now adduced, we will grant, if you please, the contrary to what we have asserted, viz. that certain unjust things are performed in this business of invocations. That the Gods, however, are not to be accused as the causes of these is immediately manifest. For those that are good are the causes of good; and the Gods possess good essentially. They do nothing, therefore, that is unjust. Hence other causes of guilty deeds must be investigated. And if we are not able to discover these causes, it is not proper to throw away the true conception respecting the Gods, nor on account of the doubts whether these unjust deeds are performed, and how they are effected, to depart from notions concerning the Gods which are truly clear. For it is much better to acknowledge the insufficiency of our power to explain how unjust actions are perpetrated, than to admit any thing impossible and false respecting the Gods; since all the Greeks and Barbarians truly opine the contrary to be the case with divine natures. After this manner, therefore, the truth respecting these particulars subsists.

(1) In what follows, in which you think that ignorance and deception about these things are impiety and impurity, and in which you exhort us to the true developement of these particulars, is not, indeed, attended with any ambiguity, but is acknowledged by all men. For who will not grant that the science which apprehends real being, is most adapted to a divine cause, but that ignorance which is hurried along to nonbeing, since it is most remote from a divine cause, falls off from truly existing forms? Since, however, what is said by you is not sufficient, I will add what is wanting; and because what you assert is rather philosophical and logical, than conformable to the efficacious art of priests, on this account I think it is necessary to say something more theurgical about these particulars.
