vigilance of caution, or the honest arts of prudent integrity, ready to accuse without malice, and to betray without treachery. Any of these may be useful to the community, and pass through the world with the reputation of good purposes and uncorrupted morals, but they are unfit for close and tender intimacies. He cannot properly be chosen for a friend, whose kindness is exhaled by its own warmth, or frozen by the first blast of slander; he cannot be a useful counsellor, who will hear no opinion but his own; he will not much invite confidence whose principal maxim is to suspect; nor can the candour and frankness of that man be much esteemed, who spreads his arms to humankind, and makes every man, without distinction, a denizen of his bosom.
That friendship may be at once fond and lasting, there must not only be equal virtue on each part, but virtue of the same kind; not only the same end must be proposed, but the same means must be approved by both. We are often, by superficial accomplishments and accidental endearments, induced to love those whom we cannot esteem; we are sometimes, by great abilities, and incontestable evidences of virtue, compelled to esteem those whom we cannot love. But friendship, compounded of esteem and love, derives from one its tenderness, and its permanence from the other; and therefore requires not only that its candidates should gain the judgment, but that they should attract the affections; that they should not only be firm in the day of distress, but gay in the hour of jollity; not only useful in exigencies, but pleasing in familiar life; their presence should give cheerfulness as well as courage, and dispel alike the gloom of fear and of melancholy.
