The true greatness of a Nation cannot be in triumphs of the intellect alone. Literature and art may widen the sphere of its influence; they may adorn it; but they are in their nature but accessaries. The true grandeur of humanity is in moral elevation, enlightened and decorated by the intellect of man. The truest tokens of this grandeur in a State are the diffusion of the greatest happiness among the greatest number, and that passionless God-like Justice, which controls the relations of the State to other States, and to all the people, who are committed to its charge.
