Again, it becomes hard for him to sympathize duly with the joys and sorrows of a large number; for then he is likely to have at the same time to rejoice with one and to grieve with another. Perhaps, then, the best plan is not to try to have as many friends as possible, but so many as are sufficient for a life in common; and indeed it would be impossible to have an ardent friendship with a great number.
And, for the same reason, it is impossible to be in love with many persons at once; for it seems that love is a sort of superlative friendship, and that this is only possible towards one person, and an ardent friendship towards a few only.
And this seems, in fact, to happen: we do not find a number of people bound together by the sort of friendship that exists between comrades, but the friendships that the poets celebrate are friendships of two persons. And the man of many friends, who is hail-fellow-well-met with everybody, seems to be really friends with no one (in any other way than as fellow-citizens are friends)—I mean the man whom we call obsequious.
