The contradictions of the Stoics (24)

In his Third Book of Dialectics, having said that Plato, Aristotle, and those who came after them, even to Polemon and Straton, but especially Socrates, diligently studied dialectics, and having cried out that one would even choose to err with such and so great men as these, he brings in these words: For if they had spoken of these things cursorily, one might perhaps have cavilled at this place; but having treated of dialectic skill as one of the greatest and most necessary faculties, it is not probable they should have been so much mistaken, having been such in all the parts of philosophy as we esteem them. Why then (might some one say to him) do you never cease to oppose and argue against such and so great men, as if you thought them to err in the principal and greatest matters? For it is not probable that they writ seriously of dialectics, and only transitorily and in sport of the beginning, end, Gods, and justice, in which you affirm their discourse to be blind and contradictory to itself, and to have a thousand other faults.
