18. Now, what is the quality to look out for as a warrant for the stability and permanence of friendship? It is loyalty. Nothing that lacks this can be stable. We should also in making our selection look out for simplicity, a social disposition, and a sympathetic nature, moved by what moves us. These all contribute to maintain loyalty. You can never trust a character which is intricate and tortuous. Nor, indeed, is it possible for one to be trustworthy and firm who is unsympathetic by nature and unmoved by what affects ourselves. We may add, that he must neither take pleasure in bringing accusations against us himself, nor believe them when they are brought. All these contribute to form that constancy which I have been endeavouring to describe. And the result is, what I started by saying, that friendship is only possible between good men. Now there are two characteristic features in his treatment of his friends that a good (which may be regarded as equivalent to a wise) man will always display. First, he will be entirely without any make-believe or pretence of feeling; for the open display even of dislike is more becoming to an ingenuous character than a studied concealment of sentiment. Secondly, he will not only reject all accusations brought against his friend by another, but he will not be suspicious himself either, nor be always thinking that his friend has acted improperly. Besides this, there should be a certain pleasantness in word and manner which adds no little flavour to friendship. A gloomy temper and unvarying gravity may be very impressive; but friendship should be a little less unbending, more indulgent and gracious, and more inclined to all kinds of good-fellowship and good-nature.
