The only thing that one really knows about human nature is that it changes. Change is the one quality we can predicate of it. The systems that fail are those that rely on the permanency of human nature, and not on its growth and development. The error of Louis XIV was that he thought human nature would always be the same. The result of his error was the French Revolution. It was an admirable result.
Oscar WildePerhaps there may come into my art also, no less than into my life, a still deeper note, one of greater unity of passion, and directness of impulse. Not width but intensity is the true aim of modern art. We are no longer in art concerned with the type. It is with the exception that we have to do. I cannot put my sufferings into any form they took, I need hardly say. Art only begins where Imitation ends, but something must come into my work, of fuller memory of words perhaps, of richer cadences, of more curious effects, of simpler architectural order, of some aesthetic quality at any rate.
Oscar WildeBehind joy and laughter there may be a temperament, coarse, hard and callous. But behind sorrow there is always sorrow. Pain, unlike pleasure, wears no mask. ... For this reason there is no truth comparable to sorrow. There are times when sorrow seems to me to be the only truth. Other things may be illusions of the eye or the appetite, made to blind the one and cloy the other, but out of sorrow have the worlds been built, and at the birth of a child or a star there is pain.
