12. Aesop’s fox indeed would not permit the hedge-hog, who offered it, to take from him the ticks that fed upon his body. For, said he, if thou remov’st those that are full, other hungry ones will succeed them. So it is of necessity, that a commonwealth which is always casting off those who grow old must be replenished with young men, thirsting after glory and power, and void of understanding in state affairs. For whence, I pray, should they have it, if they shall have been neither disciples nor spectators of any ancient statesman? For if treatises of navigation cannot make those skilful pilots who have not often in the stern been spectators of the conflicts against the waves, winds, and pitchy darkness of the night, When the poor trembling seaman longs to see The safety-boding twins, Tyndaridae; how should a raw young man take in hand the government of a city, and rightly advise both the senate and the people, having only read a book or written an exercise in the Lyceum concerning policy, though he has seldom or never stood by the reins or helm, when grave statesmen and old commanders have in debating alleged both their experiences and fortunes, whilst he was wavering on both sides, that so he might with dangers and transacting of affairs gain instruction? This is not to be said. But if it were for nothing else, yet ought an old man to manage in public affairs, that he may instruct and teach those who are young. For as those who teach children reading and music do, by pronouncing and by singing notes and tunes before them, lead and bring on their scholars; so an old statesman, not by speaking and dictating exteriorly, but by acting and administering public affairs, directs and breeds up a young one, who is by his deeds joined with his words interiorly formed and fashioned. For he who is exercised after this manner, not amongst the disputes of nimble tongued sophisters, as in the wrestling-schools and anointings, where there is not the least appearance of any danger, but really, and as it were in the Olympian and Pythian games, will tread in his teacher’s steps, Like a young colt, which runs by th’ horse’s side,— as Simonides has it. Thus Aristides followed Clisthenes, Cimon Aristides, Phocion Chabrias, Cato Fabius Maximus, Pompey Sylla, and Polybius Philopoemen; for these, when they were young, joining themselves with their elders, and afterwards as it were flourishing and growing up by their administrations and actions, gained experience, and were inured to the management of public affairs with reputation and power.
