As for disputing on both sides, he says, that he does not universally reject it, but exhorts us to use it with caution, as is done in pleadings, not with a design really to disprove, but to dissolve their probability. For to those, says he, who endeavor a suspension of assent concerning all things, it is convenient to do this, and it co-operates to what they desire; but as for those who would work and establish in us a certain science according to which we shall professedly live, they ought, on the contrary, to state the first principles, and to direct their novices who are entered from the beginning to the end; and where there is occasion to make mention of contrary discourses, to dissolve their probability, as is done in pleadings. For this he hath said in express words. Now that it is absurd for philosophers to think that they ought to set down the contrary opinion, not with all its reasons, but like pleaders, disabling it, as if they contended not for truth but victory, we have elsewhere spoken against him. But that he himself has, not here and there in his disputations, but frequently, confirmed the discourses which are contrary to his own opinions,—and that stoutly, and with so much earnestness and contention that it was not for every one to understand what he liked,—the Stoics themselves affirm, who admire the man’s acuteness, and think that Carneades said nothing of his own, but that catching hold of those arguments which Chrysippus alleged for the contrary opinion, he assaulted with them his positions, and often cried out, Wretch, thy own strength will thee undo,Il. VI. 407. as if Chrysippus had given great advantages against himself to those who would disturb and calumniate his doctrines.
