The second mode or aspect in which the Law of Tragedy as applied to history reveals itself in the life of a State, corresponds to the moment of intenser vision in the individual life, when the soul, exalted by "compassion and terror," discerns the deeper truth, the serener ideal which henceforth it pursues as if impelled by the fixed law of its being. There is a word coined by Aristotle which comes down the ages to us, bringing with it as it were the sound of the griding of the Spartan swords as they leapt from their scabbards on the morning of Thermopylae, the +enérgeia tês psychês+--the energy of the soul. This energy of the soul in Aristotle is the _vertù_ of Machiavelli, the spring of political wisdom, the foundation of the greatness of a State. It is the immortal energy which arises within the consciousness of a nation, or in the soul of an individual, as the result of that hour of insight, of pity, of anguish, or contrition. It is the heroism which adverse fortune greatens, which antagonism but excites to yet sublimer daring. In Rome this displays itself, both in policy and in war, in the centuries that immediately succeed Cannae. Nothing in history is more worthy of attention than the impression which Rome in this epoch of her history made upon the minds of men, above all, upon the mind of Hellas. Its expression in Polybius is remarkable. Polybius, if not one of the greatest of thinkers on politics, has a place with the greatest political historians for all time. It was his work which Chatham placed in the hands of his son, the younger Pitt, as the supreme guide in political history. Polybius has every inducement to abhor Rome, to judge her actions with jealous and unfriendly eyes. His father was the companion of Philopoemen, the heroic leader of the Achaean league, sometimes styled "the last of the Greeks," the Kosciusko of the old world. Polybius himself is a hostage in Rome, the representative of a defeated race, a lost cause; and yet after years of study of his conquerors, possessing every means for a just estimate of their actions and motives in the senate, on the battlefield, in the intimacies of private life, the conviction of his heart becomes that there in Rome is a people divinely appointed to the government, not of Hellas merely, but of the whole earth. The message of his history, composed with scrupulous care, and a critical method rare in that age, is that the very stars in their courses fight for Rome, whether she wages war against Greek or against Barbarian, that hers is the domination of the earth, the empire of the world, and it is to the eternal honour of Greece that it accepted this message. The Romano-Hellenic empire is born. Other men arise both to the east and to the west of the Adriatic, in whom the Greek and Roman genius are fused, who pursue the ideal and amplify or adorn the thought which Polybius was the first to express immortally. It inspires the rhetoric
