And since true friendship has three main requirements, virtue, as a thing good; and familiarity, as a thing pleasant; and use, as a thing serviceable; for we ought to choose a friend with judgement, and rejoice in his company, and make use of him in need; and all these things are prejudicial to abundance of friends, especially judgement, which is the most important point; we must first consider, if it is impossible in a short time to test dancers who are to form a chorus, or rowers who are to pull together, or slaves who are to act as stewards of estates, or as tutors of one's sons, far more difficult is it to meet with many friends who will take off their coats to aid you in every fortune, each of whom "offers his services to you in prosperity, and does not object to share your adversity." For neither does a ship encounter so many storms at sea, nor do they fortify places with walls, or harbours with defences and earthworks, in the expectation of so many and great dangers, as friendship tested well and soundly promises defence and refuge from. But if friends slip in without being tested, like money proved to be bad,
Yet is it difficult and by no means easy to avoid and bring to a close an unpleasant friendship: as in the case of food which is injurious and harmful, we cannot retain it on the stomach without damage and hurt, nor can we expel it as it was taken into the mouth, but only in a putrid mixed up and changed form, so a bad friend is troublesome both to others and himself if retained, and if he be got rid of forcibly it is with hostility and hatred, and like the voiding of bile.
§ iv. We ought not, therefore, lightly to welcome or strike up an intimate friendship with any chance comers, or love those who attach themselves to us, but attach ourselves to those who are worthy of our friendship. For what is easily got is not always desirable: and we pass over and trample upon heather and brambles that stick to us10 on our road to the olive and vine: so also is it good not always to make a friend of the person who is
