And next to these is cried up, forsooth, that goodly sentence of Plato's, "Happy is that commonwealth where a philosopher is prince, or whose prince is addicted to philosophy." When yet if you consult historians, you'll find no princes more pestilent to the commonwealth than where the empire has fallen to some smatterer in philosophy or one given to letters. To the truth of which I think the Catoes give sufficient credit; of whom the one was ever disturbing the peace of the commonwealth with his hair-brained accusations; the other, while he too wisely vindicated its liberty, quite overthrew it. Add to this the Bruti, Casii, nay Cicero himself, that was no less pernicious to the commonwealth of Rome than was Demosthenes to that of Athens. Besides M. Antoninus (that I may give you one instance that there was once one good emperor; for with much ado I can make it out) was become burdensome and hated of his subjects upon no other score but that he was so great a philosopher. But admitting him good, he did the commonwealth more hurt in leaving behind him such a son as he did than ever he did it good by his own government. For these kind of men that are so given up to the study of wisdom are generally most unfortunate, but chiefly in their children; Nature, it seems, so providently ordering it, lest this mischief of wisdom should spread further among mankind. For which reason it is manifest why Cicero's son was so degenerate, and that wise Socrates' children, as one has well observed, were more like their mother than their father, that is to say, fools.
