For as thou mayest call a carcase a dead man, but not simply a man, so I confess that the vicious are evil, but I cannot grant that they are absolutely. For that is which retaineth order, and keepeth nature, but that which faileth from this leaveth also to be that which is in his own nature. But thou wilt say that evil men can do many things, neither will I deny it, but this their power proceedeth not from forces but from weakness. For they can do evil, which they could not do if they could have remained in the performance of that which is good. Which possibility declareth more evidently that they can do nothing. For if, as we concluded a little before, evil is nothing, since they can only do evil, it is manifest that the wicked can do nothing." "It is most manifest." "And that thou mayest understand what the force of this power is; we determined a little before that there is nothing more powerful than the Sovereign Goodness." "It is true," quoth I. "But He cannot do evil." "No." "Is there any then," quoth she, "that think that men can do all things?" "No man, except he be mad, thinketh so." "But yet men can do evil." "I would to God they could not," quoth I. "Since therefore he that can only do good, can do all things, and they who can do evil, cannot do all things, it is manifest that they which can do evil are less potent. Moreover, we have proved that all power is to be accounted among those things which are to be wished for, and that all such things have reference to goodness, as to the very height of their nature. But the possibility of committing wickedness cannot have reference to goodness. Wherefore it is not to be wished for. Yet all power is to be wished for; and consequently it is manifest, possibility of evil is no power. By all which the power of the good and the undoubted infirmity of evil appeareth. And it is manifest that the sentence of Plato is true: that only wise men can do that which they desire, and that the wicked men practise indeed what they list, but cannot perform what they would. For they do what they list, thinking to obtain the good which they desire by those things which cause them delight; but they obtain it not, because shameful action cannot arrive to happiness.[146] [144] The whole of this and of the following chapter is a paraphrase of Plato's _Gorgias_.
