_Diogenes._ The bird of wisdom flies low, and seeks her food under hedges: the eagle himself would be starved if he always soared aloft and against the sun. The sweetest fruit grows near the ground, and the plants that bear it require ventilation and lopping. Were this not to be done in thy garden, every walk and alley, every plot and border, would be covered with runners and roots, with boughs and suckers. We want no poets or logicians or metaphysicians to govern us: we want practical men, honest men, continent men, unambitious men, fearful to solicit a trust, slow to accept, and resolute never to betray one. Experimentalists may be the best philosophers: they are always the worst politicians. Teach people their duties, and they will know their interests. Change as little as possible, and correct as much. Philosophers are absurd from many causes, but principally from laying out unthriftily their distinctions. They set up four virtues: fortitude, prudence, temperance, and justice. Now a man may be a very bad one, and yet possess three out of the four. Every cut-throat must, if he has been a cut-throat on many occasions, have more fortitude and more prudence than the greater part of those whom we consider as the best men. And what cruel wretches, both executioners and judges, have been strictly just! how little have they cared what gentleness, what generosity, what genius, their sentence hath removed from the earth! Temperance and beneficence contain all other virtues. Take them home, Plato; split them, expound them; do what thou wilt with them, if thou but use them.
