Whether sorrow is compatible with moral virtue?

Objections

Objection 1 : It would seem that sorrow is incompatible with virtue. Because the virtues are effects of wisdom, according to Wis. 8:7: "She," i.e. Divine wisdom, "teacheth temperance, and prudence, and justice, and fortitude." Now the "conversation" of wisdom "hath no bitterness," as we read further on (verse 16). Therefore sorrow is incompatible with virtue also.
Objection 2 : Further, sorrow is a hindrance to work, as the Philosopher states (Ethic. vii, 13; x, 5). But a hindrance to good works is incompatible with virtue. Therefore sorrow is incompatible with virtue.
Objection 3 : Further, Tully calls sorrow a disease of the mind (De Tusc. Quaest. iv). But disease of the mind is incompatible with virtue, which is a good condition of the mind. Therefore sorrow is opposed to virtue and is incompatible with it.
