It has been already stated that the good man unites the qualities of pleasantness and usefulness: but then such a one will not be a friend to a superior unless he be also his superior in goodness: for if this be not the case, he cannot, being surpassed in one point, make things equal by a proportionate degree of Friendship.[5] And characters who unite superiority of station and goodness are not common. Chapter VIII. Now all the kinds of Friendship which have been already mentioned exist in a state of equality, inasmuch as either the same results accrue to both and they wish the same things to one another, or else they barter one thing against another; pleasure, for instance, against profit: it has been said already that Friendships of this latter kind are less intense in degree and less permanent. And it is their resemblance or dissimilarity to the same thing which makes them to be thought to be and not to be Friendships: they show like Friendships in right of their likeness to that which is based on virtue (the one kind having the pleasurable, the other the profitable, both of which belong also to the other); and again, they do not show like Friendships by reason of their unlikeness to that true kind; which unlikeness consists herein, that while that is above calumny and so permanent these quickly change and differ in many other points. But there is another form of Friendship, that, namely, in which the one party is superior to the other; as between father and son, elder and younger, husband and wife, ruler and ruled. These also differ one from another: I mean, the Friendship between parents and children is not the same as between ruler and the ruled, nor has the father the same towards the son as the son towards the father, nor the husband towards the wife as she towards him; because the work, and therefore the excellence, of each of these is different, and different therefore are the causes of their feeling Friendship; distinct and different therefore are their feelings and states of Friendship. And the same results do not accrue to each from the other, nor in fact ought they to be looked for: but, when children render to their parents what they ought to the authors of their being, and parents to their sons what they ought to their offspring, the Friendship between such parties will be permanent and equitable. Further; the feeling of Friendship should be in a due proportion in all Friendships which are between superior and inferior; I mean, the better man, or the more profitable, and so forth, should be the object of a stronger feeling than he himself entertains, because when the feeling of Friendship comes to be after a certain rate then equality in a certain sense is produced, which is thought to be a requisite in Friendship.
