Wisdom is a fox who, after long hunting, will at last cost you the pains to dig out; it is a cheese, which, by how much the richer, has the thicker, the homlier, and the coarser coat; and whereof to a judicious palate, the maggots are best. It is a sack posset, wherein the deeper you go, you'll find it the sweeter. Wisdom is a hen, whose cackling we must value and consider, because it is attended with an egg. But lastly, it is a nut, which, unless you choose with judgment, may cost you a tooth, and pay you with nothing but a worm.
Jonathan SwiftThat incessant envy wherewith the common rate of mankind pursues all superior natures to their own.
