Still more striking is the expression of this fact in the proverbs of all nations, which are always the literature of reason, or the statements of an absolute truth without qualification. Proverbs, like the sacred books of each nation, are the sanctuary of the intuitions. That which the droning world, chained to appearances, will not allow the realist to say in his own words, it will suffer him to say in proverbs without contradiction. And this law of laws, which the pulpit, the senate and the college deny, is hourly preached in all markets and workshops by flights of proverbs, whose teaching is as true and as omnipresent as that of birds and flies.

All things are double, one against another. — Tit for tat; an eye for an eye; a tooth for a tooth; blood for blood; measure for measure; love for love.
