You reproach philosophers for their staff and wallet. You might as well reproach cavalry for their trappings, infantry for their shields, standard-bearers for their banners, triumphant generals for their chariots drawn by four white horses and their cloaks embroidered with palm-leaves. The staff and wallet are not, it is true, carried by the Platonic philosophers, but are the badges of the Cynic school. To Diogenes and Antisthenes they were what the crown is to the king, the cloak of purple to the general, the cowl to the priest, the trumpet to the augur. Indeed the Cynic Diogenes, when he disputed with Alexander the Great, as to which of the two was the true king, boasted of his staff as the true sceptre. The unconquered Hercules himself, since you despise my instances as drawn from mere mendicancy, Hercules that roamed the whole world, exterminated monsters, and conquered races, god though he was, had but a skin for raiment and a staff for company in the days when he wandered through the earth. And yet but a brief while afterwards he was admitted to heaven as a reward for his virtue.
