Such friendships are of course rare, because such men are few. Moreover they require time and intimacy: as the saying goes, you cannot get to know a man till you have consumed the proverbial amount of salt4 in his company; and so you cannot admit him to friendship or really be friends, before each has shown the other that he is worthy of friendship and has won his confidence. 3. [9] People who enter into friendly relations quickly have the wish to be friends, but cannot really be friends without being worthy of friendship, and also knowing each other to be so; the wish to be friends is a quick growth, but friendship is not. 4.
This form of friendship is perfect both in point of duration and of the other attributes5 of friendship; and in all respects either party receives from the other the same or similar benefits, as it is proper that friends should do.
