IV. All that you have been saying, Cato, I replied, you might say if you agreed with Pyrrho or Aristo; for you are not ignorant that they consider that honourableness not only the chief good, but also (as you yourself maintain) the only good. And if this is the case, the consequence which I see you aim at follows necessarily, that all wise men are always happy. Do you then praise these men, and do you think that we ought to follow their opinion? By no means, said he; for as this is a peculiar attribute of virtue to make its selection of those things which are in accordance with nature, those who have made all things equal in such a manner as to consider all things on either side perfectly indifferent, so as to leave no room for any selection, have utterly put an end to virtue. You say right, said I; but I ask you whether you, too, must not do the same thing, when you say that there is nothing good which is not right and honourable, and so put an end to all the difference between other things? That would be the case, said he, if I did put an end to it; but I deny the fact—I leave it. How so, said I? If virtue alone,—if that thing alone which you call honourable, right, praiseworthy, and creditable, (for it will be more easily seen what is the character that you ascribe to it, if it be pointed out by many words tending to the same point,)—if, I say, that is the sole good, what else will there be for you to follow? And, on the other hand, if nothing is evil except what is disgraceful, dishonourable, unbecoming, wrong, flagitious, and base, (to make this also manifest by giving it many names,) what else will there be which you can say ought to be avoided?
