Nevertheless, as the Philosopher says (Ethic. iv, 6) , for the sake of some good that will result, or in order to avoid some evil, the virtuous man will sometimes not shrink from bringing sorrow to those among whom he lives.

Context

“Accordingly, it belongs to the wise man to share his pleasures with those among whom he dwells, not lustful pleasures, which virtue shuns, but honest pleasures, according to Ps. 132:1, "Behold how good and how pleasant it is for brethren to dwell together in unity."
Nevertheless, as the Philosopher says (Ethic. iv, 6) , for the sake of some good that will result, or in order to avoid some evil, the virtuous man will sometimes not shrink from bringing sorrow to those among whom he lives. Hence the Apostle says (2 Cor. 7:8) : "Although I made you sorrowful by my epistle, I do not repent," and further on (2 Cor. 7:9) , "I am glad; not because you were made sorrowful, but because you were made sorrowful unto repentance."” source
