Context

“First, because sorrow is for an evil that is already present. Now they held that no evil can happen to a wise man: for they thought that, just as man's only good is virtue, and bodily goods are no good to man; so man's only evil is vice, which cannot be in a virtuous man. But this is unreasonable. For, since man is composed of soul and body, whatever conduces to preserve the life of the body, is some good to man; yet not his supreme good, because he can abuse it. Consequently the evil which is contrary to this good can be in a wise man, and can cause him moderate sorrow.” source
