“Tis surprising to see how rapidly a panic will sometimes run through a country. All nations and ages have been subject to them…. Yet panics, in some cases, have their uses; they produce as much good as hurt. Their duration is always short; the mind soon grows through them, and acquires a firmer habit than before. But their peculiar advantage is, that they are the touchstones of sincerity and hypocrisy, and bring things and men to light, which might otherwise have lain forever undiscovered. In fact, they have the same effect on secret traitors, which an imaginary apparition would have upon a private murderer. They sift out the hidden thoughts of man, and hold them up in public to the world.”

-Thomas Paine, “The American Crisis”
