If we work upon marble, it will perish; if we work on brass, time will efface it. If we rear temples, they will crumble to dust. But if we work on men’s immortal minds, if we impress on them high principles, the just fear of God, and love for their fellow-men, we engrave on those tablets something which no time can efface, and which will brighten and brighten to all eternity.
