Book 9
1
The forms which friendly feeling for our neighbors takes, and the marks by which the different forms of friendship are defined, seem to be derived from the feelings of regard which we entertain for ourselves. A friend is defined as (a) one who wishes, and promotes by action, the real or apparent good of another for that other’s sake; or (b) one who wishes the existence and preservation of his friend for the friend’s sake. (This is the feeling of mothers towards their children, and of former friends who have quarrelled.i.e., have had a difference which keeps them from meeting, but still leaves them well disposed to each other.) Others say that a friend is (c) one who frequents another’s society, and (d) who desires the same things as he does, or (e) one who shares his friend’s joys and sorrows. (This too is very characteristic of mothers.) Friendship also is defined by one or other of these marks.These five notes of friendship are taken seriatim in sects. 2-5, and again in sects. 8, 9, but in both cases the fourth is dealt with first.
2
But each of them is also found in a good man’s feelings towards himself (and in those of all other men as well, in so far as they believe themselves to be good; but, as has been said, virtue and the virtuous man seem to be the standard in everything).
3
For (d) the good man is of one mind with himself, and desires the same things with every part of his nature. Also (a) he wishes his own good, real as well as apparent, and seeks it by action (for it is a mark of a good man to exert himself actively for the good) ; and he does so for his own sake (for he does it on account of the intellectual part of himself, and this appears to be a man’s real self). Also (b) he desires his own life and security, and especially that of his rational part.
