But from whence was the Old Academy on a sudden recalled? He appears to have wished to preserve the dignity of the name, after he had given up the reality; which however some people said, that he did from a view to his own glory, and that he even hoped that those who followed him might be called Antiochians. But to me it seems, that he could not stand that concourse of all the philosophers. In truth, there are among them all, some common principles on the other points; but this doctrine is peculiar to the Academicians, and not one of the other philosophers approves of it. Therefore, he quitted it; and, like those men who, where the new shops stand, cannot bear the sun, so he, when he was hot, took refuge under the shade of the Old Academicians, as those men do under the shade of the old shops near the pillar of Mænius. There was also an argument which he was in the habit of employing, when he used to maintain that nothing could be perceived; namely, asking whether Dionysius of Heraclea had comprehended the doctrine which he had espoused for many years, because he was guided by that certain characteristic, and whether he believed the doctrine of his master Zeno, that whatever was honourable was the only good; or, whether he adopted the assertion which he defended subsequently, that the name of honourableness is a mere phantom, and that pleasure is the chief good: for from this change of opinion on his part he wished to prove, that nothing can be so stamped on our minds by the truth, that it cannot also be impressed on them in the same manner by falsehood; and so he took care that others should derive from his own conduct the same argument which he himself had derived from Dionysius.
