For since men also apply the term friends to those who love one another for profit’s sake, as happens with states (for expediency is thought to be the ground on which states make alliances), and also to those who love one another for pleasure’s sake, as children do, perhaps we too ought to apply the name to such people, and to speak of several kinds of friendship⁠—firstly, in the primary and strict sense of the word, the friendship of good men as such; secondly, the other kinds that are so called because of a resemblance to this: for these other people are called friends in so far as their relation involves some element of good, which constitutes a resemblance; for the pleasant, too, is good to those who love pleasant things. But these two latter kinds are not apt to coincide, nor do the same people become friends for the sake both of profit and pleasure; for such accidental properties are not apt to be combined in one subject.
