Compassion in the most callous heart. Hence we conclude that the entire absence of this sense is sufficient to lower a man to the last degree of villainy. (6) Compassion is the root no less of justice than of loving-kindness; but it is more clearly evidenced in the latter than in the former. We never receive proofs of genuine loving-kindness on the part of others, so long as we are in all respects prosperous. The happy man may, no doubt, often hear the words of good-will on his relations' and friends' lips; but the expression of that pure, disinterested, objective participation in the condition and lot of others, which loving-kindness begets, is reserved for him who is stricken with some sorrow or suffering, whatever it be. For the fortunate =as such= we do not feel sympathy; unless they have some other claim on us, they remain alien to our hearts: _habeant sibi sua._ (They may keep their own affairs, pleasures, etc., to themselves.) Nay, if a man has many advantages over others, he will easily become an object of envy, which is ready, should he once fall from his height of prosperity, to turn into malignant joy. Nevertheless this menace is, for the most part, not fulfilled; the Sophoclean _γελῶσι δ' ἐχθροί _ (his enemies laugh) does not generally become an actual fact. As soon as the day of ruin comes to one of fortune's spoiled children, there usually takes place a great transformation in the minds of his acquaintances, which for us in this connection is very instructive. In the first place this change clearly reveals the real nature of the interest that the friends of his happiness took in him: _diffugiunt cadis cum faece siccatis amici._ (When the casks are drained to the dregs, one's friends run away.)[4] On the other hand, the exultation of those who envied his prosperity, the mocking laugh of malicious satisfaction, which he feared more than adversity itself, and the contemplation of which he could not face, are things usually spared him. Jealousy is appeased, and disappears with its cause; while Compassion which takes its place is the parent of loving-kindness. Those who were envious of, and hostile to, a man in the full tide of success, after his downfall, have not seldom become his friends, ready to protect, comfort, and help. Who has not, at least in a small way, himself experienced something of the sort? Where is the man, who, when overtaken by some calamity, of whatever nature, has not noticed with surprise how the persons that previously had displayed the greatest coldness, nay, ill-will towards him, then came forward with unfeigned sympathy? For misfortune is the condition of Compassion, and Compassion the source of loving-kindness. When our wrath is kindled against a person, nothing quenches it so quickly, even when it is righteous, as the words: "He is an unfortunate man." And the reason is obvious: Compassion is to anger as water to fire. Therefore, whoever would fain have nothing to repent of, let him listen to my advice.
