De Stoicorum repugnantiis

Chrysippus also says, that the virtues follow one another, and that not only he who has one has all, but also that he who acts according to any one of them acts according to them all; and he affirms, that there is not any man perfect who is not possessed of all the virtues, nor any action perfect to the doing of which all the virtues do not concur. But yet in his Sixth Book of Moral Questions he says, that a good man does not always act valiantly, nor a vicious man always fearfully; for certain objects being presented to the fancies, the one must persist in his judgments, and the other depart from them; and he says that it is not probable a wicked man should be always indulging

his lust. If then to act valiantly is the same thing as to use fortitude; and to act timorously as to yield to fear, they cannot but speak contradictions who say, that he who is possessed of either virtue or vice acts at the same time according to all the virtues or all the vices, and yet that a valiant man does not always act valiantly nor a vicious man timorously.
