Those who accept each other’s company, but do not live together, seem to be rather well-wishers than friends. For there is nothing so characteristic of friendship as living together: 218 those who need help seek it thus, but even those who are happy desire company; for a solitary life suits them least of all men. But people cannot live together unless they are pleasant to each other, nor unless they take delight in the same things, which seems to be a necessary condition of comradeship.
The truest friendship, then, is that which exists between good men, as we have said again and again. For that, it seems, is lovable and desirable which is good or pleasant in itself, but to each man that which is good or pleasant to him; and the friendship of good men for one another rests on both these grounds.
