From The City of God, tr. by M. Dods
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, 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. 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. (...)
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.
