There are also some arguments which are perplexed, being veiled and escaping notice; or such as are called sorites, the horned one, or the nobody. That is a veiled argument[88] which resembles the following one; “two are not a few, nor three, nor those, nor four, and so on to ten; but two are few; therefore, so are ten few.” The nobody is a conjunctive argument, and one that consists of the indefinite and the definite, and which has a minor premiss and a conclusion; as, for instance, “If any one is here, he is not in Rhodes.” L. Such then are the doctrines which the Stoics maintain on the subject of logic, in order as far as possible to establish their point that the logician is the only wise man. For they assert that all affairs are looked at by means of that speculation which proceeds by argument, including under this assertion both those that belong to natural and also those which belong to moral philosophy: for, say they, how else could one determine the exact value of nouns, or how else could one explain what laws are imposed upon such and such actions? Moreover, as there are two habits both incidental to virtue, the one considers what each existing thing is, and the other inquires what it is called. These then are the notions of the Stoics on the subject of logic. LI. The ethical part of philosophy they divide into the topic of inclination, the topic of good and bad, the topic of the passions, the topic of virtue, the topic of the chief good, and of primary estimation, and of actions; the topic of what things are becoming, and of exhortation and dissuasion. And this division is the one laid down by Chrysippus, and Archedemus, and Zeno, of Tarsus, and Apollodorus, and Diogenes, and Antipater, and Posidonius. For Zeno, of Cittium, and Cleanthes, have, as being more ancient they were likely to, adopted a more simple method of treating these subjects. But these men divided logical and the natural philosophy.
