15. None of these things ought to be called a man's, which do not belong to a man, as man. They are not required of a man, nor does man's nature promise them, nor are they the means of man's nature attaining its end. Neither then does the end of man lie in these things, nor yet that which aids to the accomplishment of this end, and that which aids toward this end is that which is good. Besides, if any of these things did belong to man, it would not be right for a man to despise them and to set himself against them; nor would a man be worthy of praise who showed that he did not want these things, nor would he who stinted himself in any of them be good, if indeed these things were good. But now the more of these things a man deprives himself of, or of other things like them, or even when he is deprived of any of them, the more patiently he endures the loss, just in the same degree he is a better man. 16. Such as are thy habitual thoughts, such also will be the character of thy mind; for the soul is dyed by the thoughts. Dye it then with a continuous series of such thoughts as these: for instance, that where a man can live, there he can also live well. But he must live in a palace; well then, he can also live well in a palace. And again, consider that for whatever purpose each thing has been constituted, for this it has been constituted, and towards this it is carried; and its end is in that towards which it is carried; and where the end is, there also is the advantage and the good of each thing. Now the good for the reasonable animal is society; for that we are made for society has been shown above. Is it not plain that the inferior exists for the sake of the superior? But the things which have life are superior to those which have not life, and of those which have life the superior are those which have reason. 17. To seek what is impossible is madness: and it is impossible that the bad should not do something of this kind.
