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