The four cardinal virtues of Plato’s list are the qualities which go to make a healthy, normal, natural human soul, fit for all activity, equipped with all arms for the battle of life. They tell us what such a soul is, not what it does. They are the qualities which unless a soul has, and has them each perfect, yet all co-operant, its mere outward and single acts have no virtue or merit, but are only lucky accidents at the best. On the other hand, if a man has these constitutive qualities, he will act in the social world, and act well. Plato has said scornful things of mere outward and verbal truthfulness, and has set at the very lowest pitch of degradation the “lie in the soul.” His “temperance” or “self-restraint,” if it be far from breathing any suggestion of self-suppression or self-assertion, is still farther from any suspicion of asceticism, or war against the flesh. It is the noble harmony of the ruling and the ruled, which makes the latter a partner of the sovereign, and takes from the dictates of the ruler any touch of coercion. It is literally sanity of soul, integrity and purity of spirit; it is what has been sometimes called the beautiful soul—the indiscerptible unity of reason and impulse. Plato’s bravery, again, is fortitude and consistency of soul, the full-blooded heart which is fixed in reason, the zeal which is according to knowledge, unflinching loyalty to the idea, the spirit which burns in the martyrs to truth and humanity: yet withal with gentleness and courtesy and noble urbanity in its immediate train. And his truthfulness is that inner lucidity which cannot be self-deceived, the spirit which is a safeguard against fanaticism and hypocrisy, the sunlike warmth of intelligence without which the heart is a darkness full of unclean things. The full development and crowning grace of such a manly nature Aristotle has tried to present in the character of the Great-souled man—him whom Plato has called the true king by divine right, or the autocrat by the patent of nature. Like all such attempts to delineate a type in the terms necessarily single and successive of abstract analysis, it tends occasionally to run into caricature, and to give partial aspects an absurd prominency. Only the greatest of artists could cope with such a task, though that artist may be found perhaps classed among the historians. Yet it is possible to form some conception of the ideal which Aristotle would set before us. The Great-souled man _is_ great, and he dare not deny the witness of his spirit. He is one who does not quail before the anger and seek the applause of popular opinion: he holds his head as his own, and as high as his undimmed self-consciousness shows it is worth. There has been said to him by the reason within him the word that Virgil erewhile addressed to Dante: “Libero, dritto, e sano è il tuo arbitrio E fallo fora non fare a suo cenno; Per ch’ io te sopra te corono e mitrio.”
