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.[A] 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.

[A] ii. 1.

17. To seek what is impossible is madness: and it is impossible that the bad should not do something of this kind.

18. Nothing happens to any man which he is not formed by nature to bear. The same things happen to another, and either because he does not see that they have happened, or because he would show a great spirit, he is firm and remains unharmed. It is a shame then that ignorance and conceit should be stronger than wisdom.

19. Things themselves touch not the soul, not in the least degree; nor have they admission to the soul, nor can they turn or move the soul: but the soul turns and moves itself alone, and whatever judgments it may think proper to make, such it makes for itself the things which present themselves to it.
