[50] _efficiturque id quod P. ultimum in amicitia putavit ut_ Nonius (s.v. ultimum) (i.e. Pythagoras's ideal of friendship is realized). #Degrees of social relationship:# #(1) citizenship,# *53* XVII. Then, too, there are a great many degrees of closeness or remoteness in human society. To proceed beyond the universal bond of our common humanity, there is the closer one of belonging to the same people, tribe, and tongue, by which men are very closely bound together; it is a still closer relation to be citizens of the same city-state; for fellow-citizens have much in common--forum, temples, colonnades, streets, statutes, laws, courts, rights of suffrage, to say nothing of social and friendly circles and diverse business relations with many. #(2) kinship,# But a still closer social union exists between kindred. Starting with that infinite bond of union of the human race in general, the conception is now confined to a small and narrow circle. *54* For since the reproductive instinct is by nature's gift the common possession of all living creatures, the first bond of union is that between husband and wife; the next, that between parents and children; then we find one home, with everything in common. And this is the foundation of civil government, the nursery, as it were, of the state. Then follow the bonds between brothers and sisters, and next those of first and then of second cousins; and when they can no longer be sheltered under one roof, they go out into other homes, as into colonies. Then follow between these, in turn, marriages and connections by marriage, and from these again a new stock of relations; and from this propagation and after-growth states have their beginnings. The bonds of common blood hold men fast through good-will and affection; *55* for it means much to share in common the same family traditions, the same forms of domestic worship, and the same ancestral tombs. #(3) friendship,# But of all the bonds of fellowship, there is none more noble, none more powerful than when good men of congenial character are joined in intimate friendship; for really, if we discover in another that moral goodness on which I dwell so much, it attracts us and makes us friends to the one in whose character it seems to dwell. *56* And while every virtue attracts us and makes us love those who seem to possess it, still justice and generosity do so most of all. Nothing, moreover, is more conducive to love and intimacy than compatibility of character in good men; for when two people have the same ideals and the same tastes, it is a natural consequence that each loves the other as himself; and the result is, as Pythagoras requires of ideal friendship, that several are united in one. Another strong bond of fellowship is effected by mutual interchange of kind services; and as long as these kindnesses are mutual and acceptable, those between whom they are interchanged are united by the ties of an enduring intimacy.
