De Stoicorum repugnantiis

Chrysippus says, that nothing is profitable to the wicked, that the wicked have neither use nor need of any thing. Having said this in his First Book of Good Deeds, he says again, that both commodiousness and grace pertain to mean or indifferent things, none of which, according to them, is profitable. In the same place he affirms, that there is nothing proper, nothing convenient for a vicious man, in these words: On the same principle we declare that there is nothing foreign or strange to the good man, and nothing proper or rightfully belonging to the bad man, since the one is good and the other bad. Why then does he break our heads, writing particularly in every one of his books, as well natural as moral, that as soon as we are born, we are appropriated to ourselves, our parts, and our offspring? And why in his First Book of Justice does he say that the very brutes, proportionably to the necessity of their young, are appropriated to them, except fishes, whose young are nourished by themselves? For neither have they sense who have nothing sensible, nor they appropriation who have nothing proper; for appropriation seems to be the sense and perception of what is proper.
