Charles Nisbet, Popular Science Monthly (1877)
“ That an unhappy life may be happier than a happy one is indeed a paradox, but is meant in earnest. A tragedy is more delightful than a comedy. Or a comedy is better for a mixture, and strong mixture, of tragedy, so the tragedy only get digested in the end. Black is necessary not only to the relief, but even to the very composition of white. I should not choose a life of uninterrupted pleasure, were the world to engage its utmost to secure it me. The lightning is born of the darkness; and the battle, joy, and splendor of life are to be measured by the amount of opposition overcome. ”
