City of God, Book VIII
Chapter 3. Of the Socratic Philosophy
Socrates is said to have been the first who directed the entire effort of philosophy to the correction and regulation of manners, all who went before him having expended their greatest efforts in the investigation of physical, that is, natural phenomena. However, it seems to me that it cannot be certainly discovered whether Socrates did this because he was wearied of obscure and uncertain things, and so wished to direct his mind to the discovery of something manifest and certain, which was necessary in order to the obtaining of a blessed life,—that one great object toward which the labor, vigilance, and industry of all philosophers seem to have been directed,—or whether (as some yet more favorable to him suppose) he did it because he was unwilling that minds defiled with earthly desires should essay to raise themselves upward to divine things. For he saw that the causes of things were sought for by them,—which causes he believed to be ultimately reducible to nothing else than the will of the one true and supreme God,—and on this account he thought they could only be comprehended by a purified mind; and therefore that all diligence ought to be given to the purification of the life by good morals, in order that the mind, delivered from the depressing weight of lusts, might raise itself upward by its native vigor to eternal things, and might, with purified understanding, contemplate that nature which is incorporeal and unchangeable light, where live the causes of all created natures.
It is evident, however, that he hunted out and pursued, with a wonderful pleasantness of style and argument, and with a most pointed and insinuating urbanity, the foolishness of ignorant men, who thought that they knew this or that,—sometimes confessing his own ignorance, and sometimes dissimulating his knowledge, even in those very moral questions to which he seems to have directed the whole force of his mind. And hence there arose hostility against him, which ended in his being calumniously impeached, and condemned to death. Afterwards, however, that very city of the Athenians, which had publicly condemned him, did publicly bewail him,—the popular indignation having turned with such vehemence on his accusers, that one of them perished by the violence of the multitude, whilst the other only escaped a like punishment by voluntary and perpetual exile.
Illustrious, therefore, both in his life and in his death, Socrates left very many disciples of his philosophy, who vied with one another in desire for proficiency in handling those moral questions which concern the chief good (summum bonum), the possession of which can make a man blessed; and because, in the disputations of Socrates, where he raises all manner of questions, makes assertions, and then demolishes them, it did not evidently appear what he held to be the chief good, every one took from these disputations what pleased him best, and every one placed the final good in whatever it appeared to himself to consist. Now, that which is called the final good is that at which, when one has arrived, he is blessed. But so diverse were the opinions held by those followers of Socrates concerning this final good, that (a thing scarcely to be credited with respect to the followers of one master) some placed the chief good in pleasure, as Aristippus, others in virtue, as Antisthenes. Indeed, it were tedious to recount the various opinions of various disciples.
Chapter 4.—Concerning Plato, the Chief Among the Disciples of Socrates, and His Threefold Division of Philosophy.
But, among the disciples of Socrates, Plato was the one who shone with a glory which far excelled that of the others, and who not unjustly eclipsed them all. By birth, an Athenian of honorable parentage, he far surpassed his fellow-disciples in natural endowments, of which he was possessed in a wonderful degree. Yet, deeming himself and the Socratic discipline far from sufficient for bringing philosophy to perfection, he travelled as extensively as he was able, going to every place famed for the cultivation of any science of which he could make himself master. Thus he learned from the Egyptians whatever they held and taught as important; and from Egypt, passing into those parts of Italy which were filled with the fame of the Pythagoreans, he mastered, with the greatest facility, and under the most eminent teachers, all the Italic philosophy which was then in vogue. And, as he had a peculiar love for his master Socrates, he made him the speaker in all his dialogues, putting into his mouth whatever he had learned, either from others, or from the efforts of his own powerful intellect, tempering even his moral disputations with the grace and politeness of the Socratic style. And, as the study of wisdom consists in action and contemplation, so that one part of it may be called active, and the other contemplative,—the active part having reference to the conduct of life, that is, to the regulation of morals, and the contemplative part to the investigation into the causes of nature and into pure truth,—Socrates is said to have excelled in the active part of that study, while Pythagoras gave more attention to its contemplative part, on which he brought to bear all the force of his great intellect. To Plato is given the praise of having perfected philosophy by combining both parts into one. He then divides it into three parts,—the first moral, which is chiefly occupied with action; the second natural, of which the object is contemplation; and the third rational, which discriminates between the true and the false. And though this last is necessary both to action and contemplation, it is contemplation, nevertheless, which lays peculiar claim to the office of investigating the nature of truth. Thus this tripartite division is not contrary to that which made the study of wisdom to consist in action and contemplation.
Now, as to what Plato thought with respect to each of these parts,—that is, what he believed to be the end of all actions, the cause of all natures, and the light of all intelligences,—it would be a question too long to discuss, and about which we ought not to make any rash affirmation. For, as Plato liked and constantly affected the well-known method of his master Socrates, namely, that of dissimulating his knowledge or his opinions, it is not easy to discover clearly what he himself thought on various matters, any more than it is to discover what were the real opinions of Socrates. We must, nevertheless, insert into our work certain of those opinions which he expresses in his writings, whether he himself uttered them, or narrates them as expressed by others, and seems himself to approve of,—opinions sometimes favorable to the true religion, which our faith takes up and defends, and sometimes contrary to it, as, for example, in the questions concerning the existence of one God or of many, as it relates to the truly blessed life which is to be after death.
For those who are praised as having most closely followed Plato, who is justly preferred to all the other philosophers of the Gentiles, and who are said to have manifested the greatest acuteness in understanding him, do perhaps entertain such an idea of God as to admit that in Him are to be found the cause of existence, the ultimate reason for the understanding, and the end in reference to which the whole life is to be regulated. Of which three things, the first is understood to pertain to the natural, the second to the rational, and the third to the moral part of philosophy. For if man has been so created as to attain, through that which is most excellent in him, to that which excels all things,—that is, to the one true and absolutely good God, without whom no nature exists, no doctrine instructs, no exercise profits,—let Him be sought in whom all things are secure to us, let Him be discovered in whom all truth becomes certain to us, let Him be loved in whom all becomes right to us.
Chapter 5.—That It is Especially with the Platonists that We Must Carry on Our Disputations on Matters of Theology, Their Opinions Being Preferable to Those of All Other Philosophers.
If, then, Plato defined the wise man as one who imitates, knows, loves this God, and who is rendered blessed through fellowship with Him in His own blessedness, why discuss with the other philosophers? It is evident that none come nearer to us than the Platonists. To them, therefore, let that fabulous theology give place which delights the minds of men with the crimes of the gods; and that civil theology also, in which impure demons, under the name of gods, have seduced the peoples of the earth given up to earthly pleasures, desiring to be honored by the errors of men, and by filling the minds of their worshippers with impure desires, exciting them to make the representation of their crimes one of the rites of their worship, whilst they themselves found in the spectators of these exhibitions a most pleasing spectacle,—a theology in which, whatever was honorable in the temple, was defiled by its mixture with the obscenity of the theatre, and whatever was base in the theatre was vindicated by the abominations of the temples. To these philosophers also the interpretations of Varro must give place, in which he explains the sacred rites as having reference to heaven and earth, and to the seeds and operations of perishable things; for, in the first place, those rites have not the signification which he would have men believe is attached to them, and therefore truth does not follow him in his attempt so to interpret them; and even if they had this signification, still those things ought not to be worshipped by the rational soul as its god which are placed below it in the scale of nature, nor ought the soul to prefer to itself as gods things to which the true God has given it the preference. The same must be said of those writings pertaining to the sacred rites, which Numa Pompilius took care to conceal by causing them to be buried along with himself, and which, when they were afterwards turned up by the plough, were burned by order of the senate. And, to treat Numa with all honor, let us mention as belonging to the same rank as these writings that which Alexander of Macedon wrote to his mother as communicated to him by Leo, an Egyptian high priest.
In this letter not only Picus and Faunus, and Æneas and Romulus or even Hercules, and Æsculapius and Liber, born of Semele, and the twin sons of Tyndareus, or any other mortals who have been deified, but even the principal gods themselves, to whom Cicero, in his Tusculan questions, alludes without mentioning their names, Jupiter, Juno, Saturn, Vulcan, Vesta, and many others whom Varro attempts to identify with the parts or the elements of the world, are shown to have been men. There is, as we have said, a similarity between this case and that of Numa; for the priest being afraid because he had revealed a mystery, earnestly begged of Alexander to command his mother to burn the letter which conveyed these communications to her.
Let these two theologies, then, the fabulous and the civil, give place to the Platonic philosophers, who have recognized the true God as the author of all things, the source of the light of truth, and the bountiful bestower of all blessedness.
