text: Let us now return to the question. The wise man, I say, self-sufficient though he be, nevertheless desires friends if only for the purpose of practising friendship, in order that his noble qualities may not lie dormant. Not, however, for the purpose mentioned by Epicurus in the letter quoted above: "That there may be someone to sit by him when he is ill, to help him when he is in prison or in want;" but that he may have someone by whose sick-bed he himself may sit, someone a prisoner in hostile hands whom he himself may set free. He who regards himself only, and enters upon friendships for this reason, reckons wrongly. The end will be like the beginning: he has made friends with one who might assist him out of bondage; at the first rattle of the chain such a friend will desert him. These are the so-called "fair-weather" friendships; one who is chosen for the sake of utility will be satisfactory only so long as he is useful. Hence prosperous men are blockaded by troops of friends; but those who have failed stand amid vast loneliness, their friends fleeing from the very crisis which is to test their worth. Hence, also, we notice those many shameful cases of persons who, through fear, desert or betray. The beginning and the end cannot but harmonize. He who begins to be your friend because it pays will also cease because it pays. A man will be attracted by some reward offered in exchange for his friendship, if he be attracted by aught in friendship other than friendship itself.
