^11. Finally, suppose that you, being asked all those questions which you have submitted to me, have been able to answer them all. Behold! You are now spoken of as most learned and most acute; behold! now this insignificant breath of Greek laudation raises you to heaven. Be it yours now to remember your responsibilities and the end for which you coveted these praises, namely, that to men who have been easily won to admire you by these trifles, and who are now hanging most affectionately and eagerly on your lips, you may impart some truly important and wholesome instruction; and I should like to know whether you possess, and can rightly impart to others, that which is truly most important and wholesome. For it is absurd if, after learning many unnecessary things with a view to preparing the ears of men to receive what is necessary, you be found not to possess those necessary things for the reception of which you have by these unnecessary things prepared the way; it is absurd if, while busying yourself with learning things by which you may win men's attention, you refuse to learn that which may be poured into their minds when their attention is secured. But if you reply that you have already learned this, and say that the truth supremely necessary is Christian doctrine, which I know that you esteem above all other things, placing in it alone your hope of everlasting salvation, then surely this does not demand a knowledge of the Dialogues of Cicero, and a collection of the beggarly and divided opinions of other men, in order to your persuading men to give it a hearing. Let your character and manner of life command the attention of those who are to receive any such teaching from you. I would not have you open the way for teaching truth by first teaching what must be afterwards unlearned.

12. For if the knowledge of the discordant and mutually contradictory opinions of others is of any service to him who would obtain an entrance for Christian truth in overthrowing the opposition of error, it is useful only in the way of preventing the assailant of the truth from being at liberty to fix his eye solely on the work of controverting your tenets, while carefully hiding his own from view. For the knowledge of the truth is of itself sufficient both to detect and to subvert all errors, even those which may not have been heard before, if only they are brought forward. If, however, in order to secure not only the demolition of open errors, but also the rooting out of those which lurk in darkness, it is necessary for you to be acquainted with the erroneous opinions which others have advanced, let both eye and ear be wakeful, I beseech you—look well and listen well whether any of our assailants bring forward a single argument from Anaximenes and from Anaxagoras, when, though the Stoic and Epicurean philosophies were more recent and taught largely, even their ashes are not so warm as that a single spark can be struck out from them against the Christian faith. The din which resounds in the battlefield of controversy now comes from innumerable small companies and cliques of sectaries, some of them easily discomfited, others presuming to make bold resistance—such as the partisans of Donatus, Maximian, and Manichæus here, or the unruly herds of Arians, Eunomians, Macedonians, and Cataphrygians and other pests which abound in the countries to which you are on your way. If you shrink from the task of acquainting yourself with the errors of all these sects, what occasion have we in defending the Christian religion to inquire after the tenets of Anaximenes, and with idle curiosity to awaken anew controversies which have slept for ages, when already the cavillings and arguments even of some of the heretics who claimed the glory of the Christian name, such as the Marcionites and the Sabellians, and many more, have been put to silence? Nevertheless, if it be necessary, as I have said, to know beforehand some of the opinions which war against the truth, and become thoroughly conversant with these, it is our duty to give a place in such study to the heretics who call themselves Christians, much rather than to Anaxagoras and Democritus.
