He used also to divide things, according to Aristotle, in the following manner. The third appendix begins here, containing the διαιρέσεις which are also attributed to Aristotle; see Rose, Aristoteles Pseudepigraphus, pp. 679 sqq., who gives a Christian recension. The original, the common source of Diogenes Laertius and the Christian writer, he refers vaguely to the Hellenistio age. Goods are in the mind or in the body, or external. For example, justice, prudence, courage, temperance and such like are in the mind; beauty, a good constitution, health and strength in the body; while friends, the welfare of one’s country and riches are amongst external things.
1.81
Thus there are three kinds of goods: goods of the mind, goods of the body and external goods. There are three species of friendship: one species is natural, another social, and another hospitable. By natural friendship we mean the affection which parents have for their offspring and kinsmen for each other. And other animals besides man have inherited this form.
1.81
By the social form of friendship we mean that which arises from intimacy and has nothing to do with kinship; for instance, that of Pylades for Orestes. The friendship of hospitality is that which is extended to strangers owing to an introduction or letters of recommendation. Thus friendship is either natural or social or hospitable. Some add a fourth species, that of love.
