Plutarch, De communibus notitiis adversus Stoicos
Goodwin, Ed.

Nor is this less repugnant to common sense, that an intelligent and prudent man should not be equally affected to equal good things, but should put no value on some, and be ready to undergo and suffer any thing for others, though the things themselves are neither greater nor less one than another. For they say, It is the same thing to abstain from the enjoyment of an old woman that has one foot in the grave, and...since in both cases we do what duty requires. And yet for this, as a great and glorious thing, they should be ready to die; when as to boast of the other would be shameful and ridiculous. And even Chrysippus himself in his commentary concerning Jupiter, and in the Third Book of the Gods, says, that it were a poor, absurd, and impertinent thing to glory in such acts, as proceeding from virtue, as bearing valiantly the stinging of a wasp, or abstaining chastely from an old woman that lies a dying. Do not they then philosophize against the common conception, who profess nothing to be more commendable than those things which yet themselves are ashamed to praise? For how can that be desirable or to be approved, which is worthy neither of praise nor admiration, but the praisers and admirers of which they esteem absurd and ridiculous?
