^16. Among those, again, who say that our supreme and only good is to enjoy God, by whom both we ourselves and all things were made, the most eminent have been the Platonists, who not unreasonably judged it to belong to their duty to confute the Stoics and Epicureans— the latter especially, and almost exclusively. The Academic School is identical with the Platonists, as is shown plainly enough by the links of unbroken succession connecting the schools. For if you ask who was the predecessor of Arcesilas, the first who, announcing no doctrine of his own, set himself to the one work of refuting the Stoics and Epicureans, you will find that it was Polemo; ask who preceded Polemo, it was Xenocrates; but Xenocrates was Plato's disciple, and by him appointed his successor in the academy. Wherefore, as to this question concerning the supreme good, if we set aside the representatives of conflicting views, and consider the abstract question, you find at once that two errors confront each other as diametrically opposed— the one declaring the body, and the other declaring the mind to be the seat of the supreme good of men. You find also that truly enlightened reason, by which God is perceived to be our supreme good, is opposed to both of these errors, but does not impart the knowledge of what is true until it has first made men unlearn what is false. If now you consider the question in connection with the advocates of different views, you will find the Epicureans and Stoics most keenly contending with each other, and the Platonists, on the other hand, endeavouring to decide the controversy between them, concealing the truth which they held, and devoting themselves only to prove and overthrow the vain confidence with which the others adhered to error.

17. It was not in the power of the Platonists, however, to be so efficient in supporting the side of reason enlightened by truth, as the others were in supporting their own errors. For from them all there was then withheld that example of divine humility, which, in the fullness of time, was furnished by our Lord Jesus Christ—that one example before which, even in the mind of the most headstrong and arrogant, all pride bends, breaks, and dies. And therefore the Platonists, not being able by their authority to lead the mass of mankind, blinded by love of earthly things, into faith in things invisible—although they saw them moved, especially by the arguments of the Epicureans, not only to drink freely the cup of the pleasures of the body to which they were naturally inclined, but even to plead for these, affirming that they constitute man's highest good; although, moreover, they saw that those who were moved to abstinence from these pleasures by the praise of virtue found it easier to regard pleasure as having its true seat in the soul, whence the good actions, concerning which they were able, in some measure, to form an opinion, proceeded—at the same time, saw that if they attempted to introduce into the minds of men the notion of something divine and supremely immutable, which cannot be reached by any one of the bodily senses, but is apprehensible only by reason, which, nevertheless, surpasses in its nature the mind itself, and were to teach that this is God, set before the human soul to be enjoyed by it when purged from all stains of human desires, in whom alone every longing after happiness finds rest, and in whom alone we ought to find the consummation of all good—men would not understand them, and would much more readily award the palm to their antagonists, whether Epicureans or Stoics; the result of which would be a thing most disastrous to the human race, namely, that the doctrine, which is true and profitable, would become sullied by the contempt of the uneducated masses. So much in regard to Ethical questions.

18. As to Physics, if the Platonists taught that the originating cause of all natures is immaterial wisdom, and if, on the other hand, the rival sects of philosophers never got above material things, while the beginning of all things was attributed by some to atoms, by others to the four elements, in which fire was of special power in the construction of all things—who could fail to see to which opinion a favourable verdict would be given, when the great mass of unthinking men are enthralled by material things, and can in no wise comprehend that an immaterial power could form the universe?

19. The department of dialectic questions remains to be discussed; for, as you are aware, all questions in the pursuit of wisdom are classified under three heads—Ethics, Physics, and Dialectics. When, therefore, the Epicureans said that the senses are never deceived, and, though the Stoics admitted that they sometimes are mistaken, both placed in the senses the standard by which truth is to be comprehended, who would listen to the Platonists when both of these sects opposed them? Who would look upon them as entitled to be esteemed men at all, and much less wise men, if, without hesitation or qualification, they affirmed not only that there is something which cannot be discerned by touch, or smell, or taste, or hearing, or sight, and which cannot be conceived of by any image borrowed from the things with which the senses acquaint us, but that this alone truly exists, and is alone capable of being perceived, because it is alone unchangeable and eternal, but is perceived only by reason, the faculty whereby alone truth, in so far as it can be discovered by us, is found?

20. Seeing, therefore, that the Platonists held opinions which they could not impart to men enthralled by the flesh; seeing also that they were not of such authority among the common people as to persuade them to accept what they ought to believe until the mind should be trained to that condition in which these things can be understood—they chose to hide their own opinions, and to content themselves with arguing against those who, although they affirmed that the discovery of truth is made through the senses of the body, boasted that they had found the truth. And truly, what occasion have we to inquire as to the nature of their teaching? We know that it was not divine, nor invested with any divine authority. But this one fact merits our attention, that whereas Plato is in many ways most clearly proved by Cicero to have placed both the supreme good and the causes of things, and the certainty of the processes of reason, in Wisdom, not human, but divine, whence in some way the light of human wisdom is derived— in Wisdom which is wholly immutable, and in Truth always consistent with itself; and whereas we also learn from Cicero that the followers of Plato laboured to overthrow the philosophers known as Epicureans and Stoics, who placed the supreme good, the causes of things, and the certainty of the processes of reason, in the nature either of body or of mind—the controversy had continued rolling on with successive centuries, so that even at the commencement of the Christian era, when the faith of things invisible and eternal was with saving power preached by means of visible miracles to men, who could neither see nor imagine anything beyond things material, these same Epicureans and Stoics are found in the Acts of the Apostles to have opposed themselves to the blessed Apostle Paul, who was beginning to scatter the seeds of that faith among the Gentiles.

21. By which thing it seems to me to be sufficiently proved that the errors of the Gentiles in ethics, physics, and the mode of seeking truth, errors many and manifold, but conspicuously represented in these two schools of philosophy, continued even down to the Christian era, notwithstanding the fact that the learned assailed them most vehemently, and employed both remarkable skill and abundant labour in subverting them. Yet these errors we see in our time to have been already so completely silenced, that now in our schools of rhetoric the question what their opinions were is scarcely ever mentioned; and these controversies have been now so completely eradicated or suppressed in even the Greek gymnasia, notably fond of discussion, that whenever now any school of error lifts up its head against the truth, i.e. against the Church of Christ, it does not venture to leap into the arena except under the shield of the Christian name. Whence it is obvious that the Platonist school of philosophers felt it necessary, having changed those few things in their opinions which Christian teaching condemned, to submit with pious homage to Christ, the only King who is invincible, and to apprehend the Incarnate Word of God, at whose command the truth which they had even feared to publish was immediately believed.
