In every one of his natural and ethical books, he asserts vice to be the very essence of unhappiness; writing and contending that to live viciously is the same thing as to live unhappily. But in his Third Book of Nature, having said that it is profitable for a fool to live rather than to die, though he is never to become wise, he subjoins: For such is the nature of good things among men, that evil things are in some sort preferred before indifferent ones. I let pass therefore, that having elsewhere said that nothing is profitable to fools, he here says that to live foolishly is profitable to them. Now those things being by them called indifferent which are neither bad nor good, when he says that bad things precede them, he says nothing else but that evil things precede those that are not evil, and that to be unhappy is more profitable than not to be unhappy; and if so, he esteems not to be unhappy to be more unprofitable—and if more unprofitable, more hurtful—than to be unhappy. Desiring therefore to mitigate this absurdity, he adds concerning evils: But it is not these evils that are preferred, but reason; with which it is more convenient to live, though we shall be fools. First therefore he says that vice and things participating of vice are evil, and that nothing else is so. Now vice is something reasonable, or rather depraved reason. For those therefore who are fools to live with reason, is nothing else but to live with vice. Thence to live being fools is to live being unhappy. In what then is this preferred to indifferent things? For he surely will not say that with regard to happiness unhappiness is to be preferred. But neither, say they, does Chrysippus altogether think that the remaining in life is to be reckoned amongst good things, or the going out of it amongst bad; but both of them amongst indifferent ones, according to Nature. Wherefore also it sometimes becomes meet for the happy to make themselves away, and again for the unhappy to continue in life. Now what greater repugnance can there be than this in the choice and avoiding of things, if it is convenient for those who are in the highest degree happy to forsake those good things that are present, for the want of some one indifferent thing? And yet they esteem none of the indifferent things either desirable or to be avoided; but only good desirable, and only evil to be avoided. So that it comes to pass, according to them, that the reasoning about actions regards neither things desirable nor things refusable; but that aiming at other things, which they neither shun nor choose, they make life and death dependent on these.
