Famous quotes containing the words truth and/or predicate:
“As the will to truth thus gains self-consciousness—there can be no doubt of that—morality will gradually perish now: this is the great spectacle in a hundred acts reserved for the next two centuries in Europe—the most terrible, most questionable, and perhaps also the most hopeful of all spectacles.”
—Friedrich Nietzsche (1844–1900)
“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 Wilde (1854–1900)
