Discourses: Book 2 23 : 6
But to do away with the faculty of eloquence and to say that in all truth it is nothing is the act not merely of a man ungrateful to those who have given it, but also cowardly. For such a person seems to me to be afraid that, if there really is a faculty of this kind, we may not be able to despise it. Such also are those who assert that there is no difference between beauty and ugliness. What! could a man be affected in the same way by the sight of Thersites and that of Achilles? Or by the sight of Helen and that of some ordinary woman? But these are the notions of foolish and boorish persons who do not know the nature of each several thing, but are afraid that if a man notices the superiority of the faculty in question he will immediately be carried away by it and come off worsted. Nay, the great thing is this: to leave each in the possession of his own proper faculty, and, so leaving him, to observe the value of the faculty, and to learn what is the highest of all things, and in everything to pursue after this, to be zealous about this, treating all other things as of secondary value in comparison with it, though without neglecting these, as far as this is possible. For we must take care of our eyes too, yet not as the highest thing, but we must take care of them for the sake of the highest; because this latter will not have its natural perfection unless it uses the eyes with reason and chooses one thing instead of another.
