"Plato was right: ideas rule the world, and, as men's minds will receive new ideas, laying aside the old and effete, the world will advance: mighty revolutions will spring from them; creeds and even powers will crumble before their onward march crushed by the irresistible force. It will be just as impossible to resist their influx, when the time comes, as to stay the progress of the tide. But all this will come gradually on, and before it comes we have a duty set before us; that of sweeping away as much as possible the dross left to us by our pious forefathers. New ideas have to be planted on clean places, for these ideas touch upon the most momentous subjects."
