Since a human being is a mortal rational animal, social by nature, they say that all human virtue and happiness are a life of consistency and agreement with nature.287
Zeno and Cleanthes on the End
II.7.6a.1 · Wachsmuth pp. 75-76
Zeno defined the end thus: “to live in agreement.” This means living according to a single, harmonious rational principle, since those who live in conflict are unhappy.288 Those after him made the formulation more explicit: “to live in agreement with nature,” taking the predicate stated by Zeno to be incomplete. For Cleanthes, the first to succeed him in the school, added “with nature” and defined it thus: “The end is to live in agreement with nature.”289
Chrysippus Diogenes and Archedemus on the End
II.7.6a.2 · Wachsmuth pp. 76
Chrysippus, wishing to make this clearer, expressed it thus: “to live in accordance with experience of what happens by nature.” Diogenes said: “to reason well in selecting and rejecting things in accordance with nature.”290 Archedemus said: “to live carrying out all appropriate actions.”291
Antipater on the End
II.7.6a.3 · Wachsmuth pp. 76
Antipater said: “to live continually selecting what is in accordance with nature and rejecting what is contrary to nature.”292 They also frequently defined it thus: “continually and unswervingly to do everything in one’s power toward obtaining the things preferred in accordance with nature.”293
Three Senses of the End
II.7.6b · Wachsmuth pp. 76
Those of this school use “end” in three senses. In learned usage the final good is called an end, as when they say that agreement is the end.294 They also call the target an end, for example the life in agreement, speaking by reference to the corresponding predicate. In the third sense they call the end the ultimate among the objects of desire, to which all the others are referred.295
End and Target
II.7.6c · Wachsmuth pp. 77
They hold that end and target differ. The target, they say, is the body set before one, which those who aim at happiness strive to attain [text missing],296 since every virtuous person is happy and, conversely, every base person is unhappy.297
Goods Necessary for Happiness
II.7.6d.1 · Wachsmuth pp. 77
Of goods, some are necessary for happiness and some are not. All the virtues and the activities that exercise them are necessary; joy, gladness, and cultivated pursuits are not necessary.298
Evils Necessary for Unhappiness
II.7.6d.2 · Wachsmuth pp. 77
Similarly, of evils, some are necessary, as evils, for unhappiness, and some are not necessary. All the vices and the activities based on them are necessary; all the passions, the infirmities, and similar things are not necessary.299
Being Happy as the End
II.7.6e.1 · Wachsmuth pp. 77
They say that the end is being happy, for the sake of which everything is done, while it itself is done for the sake of nothing else. This consists in living in accordance with virtue, in living in agreement, and further, since it is the same thing, in living in accordance with nature.300 Zeno defined happiness thus: “Happiness is a good flow of life.”301
Happiness and Its Attainment
II.7.6e.2 · Wachsmuth pp. 77
Cleanthes too used this definition in his own writings, as did Chrysippus and all their successors. They say that happiness is no different from the happy life, although they also say that happiness is set before one as the target, while the end is attaining happiness, which is the same as being happy.302
Living in Accordance with Nature and Virtue
II.7.6e.3 · Wachsmuth pp. 78
It is therefore clear from these points that “living in accordance with nature,” “living nobly,” and “living well” are equivalent; and likewise “the noble and good” and “virtue and what participates in virtue.”303 Every good is noble, and similarly every shameful thing is evil. Hence the Stoic end is equivalent to the life in accordance with virtue.304
Choiceworthy and To Be Chosen
II.7.6f.1 · Wachsmuth pp. 78
They say that what is choiceworthy differs from what is to be chosen. Every ⟨good⟩ is choiceworthy; every benefit is to be chosen, and is considered in connection with having the good.305 We therefore choose what is to be chosen, for example thinking wisely, which is considered in connection with having practical wisdom. We do not choose what is choiceworthy; if anything, we choose to have it.306
Endurance and Adherence
II.7.6f.2 · Wachsmuth pp. 78
Similarly, all goods are worthy of being endured and held to, and the same analogy applies to the other virtues, even if they have not been named. All benefits, however, are to be endured and held to.307 The same account applies to the other cases concerning the vices.308
