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.
The more one analyses people, the more all reasons for analysis disappear. Sooner or later one comes to that dreadful universal thing called human nature.
As for borrowing Mr. Whistler's ideas about art, the only thoroughly original ideas I have heard him express have had reference to his own superiority as a painter over painters greater than himself.
The ugly and stupid have the best of it in this world. They can sit at their ease and gape at the play. If they know nothing of victory, they are at least spared the knowledge of defeat. They live as we all should live-- undisturbed, indifferent, and without disquiet. They never bring ruin upon others, nor ever receive it from alien hands. Your rank and wealth, Henry; my brains, such as they are-- my art, whatever it may be worth; Dorian Gray's good looks-- we shall all suffer for what the gods have given us, suffer terribly.
