Remember, that the end of true friendship is the good of its object, and the cultivation of virtue, in two hearts emulous of each other, and desirous to perpetuate their society beyond the grave. Nothing can be more contrary to this end than that mutual intercourse of flattery, which some call friendship. A real friend will venture to displease me, rather than indulge my faulty inclinations, or increase my natural frailties; she will endeavour to make me acquainted with myself, and will put me upon guarding the weak parts of my character.

Friendship, in the highest sense of the word, can only subsist between persons of strict integrity and true generosity. Before you fancy yourself possessed of such a treasure, you should examine the value of your own heart, and see how well it is qualified for so sacred a connection; and then a harder task remains—to find out whether the object of your affection is also endued with the same virtuous disposition. Youth and inexperience are ill able to penetrate into characters: the least appearance of good attracts their admiration, and they immediately suppose they have found the object they pursued.

It is a melancholy consideration, that the judgement can only be formed by experience, which generally comes too late for our own use, and is seldom accepted for that of others. I fear it is in vain for me to tell you what dangerous mistakes I made in the early choice of friends—how incapable I then was of finding out such as were fit for me, and how little I was acquainted with the true nature of friendship, when I thought myself most fervently engaged in it! I am sensible all this will hardly persuade you to choose by the eyes of others, or even to suspect that your own may be deceived. Yet, if you should give any weight to my observations, it may not be quite useless to mention to you some of the essential requisites in a friend; and to exhort you never to choose one in whom they are wanting.

The first of these is a deep and sincere regard for religion. If your friend draws her principles from the same source with yourself, if the gospel precepts are the rule of her life, as well as your's, you will always know what to expect from her, and have one common standard of right and wrong to refer to, by which to regulate all material points of conduct. The woman who thinks lightly of sacred things, or who is ever heard to speak of them with levity or indifference, cannot reasonably be expected to pay a more serious regard to the laws of friendship, or to be uniformly punctual in the performance of any of the duties of society; take no such person to your bosom, however recommended by good-humour, wit, or any other qualification; nor let gaiety or thoughtlessness be deemed an excuse for offending in this important point: a person habituated to the love and reverence of religion and virtue, no more wants the guard of serious consideration to restrain her from speaking disrespectfully of them, than to prevent her speaking ill of her dearest friend. In the liveliest hour of mirth, the innocent heart can dictate nothing but what is innocent; it will immediately take alarm at the apprehension of doing wrong, and stop at once in the full career of youthful sprightliness, if reminded of the neglect or transgression of any duty. Watch for these symptoms of innocence and goodness, and admit no one to your entire affection, who would ever persuade you to make light of any sort of offence, or who can treat with levity or contempt any person or thing that bears a relation to religion.

A due regard to reputation is the next indispensable qualification.—"Have regard to thy name," saith the wise son of Sirach, "for that will continue with thee above a thousand great treasures of gold." The young person, who is careless of blame, and indifferent to the esteem of the wise and prudent part of the world, is not only a most dangerous companion, but gives a certain proof of the want of rectitude in her own mind. Discretion is the guardian of all the virtues; and, when she forsakes them, they cannot long resist the attacks of an enemy. There is a profligacy of spirit in defying the rules of decorum, and despising censure, which seldom ends otherwise than in extreme corruption and utter ruin. Modesty and prudence are qualities that early display themselves, and are easily discerned: where these do not appear, you should avoid, not only friendship, but every step towards intimacy, lest your own character should suffer with that of your companion; but, where they shine forth in any eminent degree, you may safely cultivate an acquaintance, in the reasonable hope of finding the solid fruits of virtue beneath such sweet and promising blossoms: should you be disappointed, you will at least have run no risk in the search after them, and may cherish as a creditable acquaintance the person so adorned, though she may not deserve a place in your inmost heart.

The understanding must next be examined: and this is a point which requires so much understanding to judge of in another, that I must earnestly recommend to you, not to rely entirely on your own, but to take the opinion of your older friends. I do not wish you to seek for bright and uncommon talents, though these are sources of inexhaustible delight and improvement, when found in company with solid judgment and sound principles. Good sense (by which I mean a capacity for reasoning justly and discerning truly) applied to the uses of life, and exercised in distinguishing characters and directing conduct, is alone necessary to an intimate connection; but, without this, the best intentions, though certain of reward hereafter, may fail of producing their effects in this life; nor can they singly constitute the character of an useful and valuable friend. On the other hand, the most dazzling genius, or the most engaging wit and humour, can but ill answer the purposes of friendship, without plain common sense and a faculty of just reasoning.

What can one do with those who will not be answered with reason, and who, when you are endeavouring to convince or persuade them by serious arguments, will parry the blow with a witty repartee or a stroke of poignant raillery? I know not whether such a reply is less provoking than that of an obstinate fool, who answers your strongest reasons with—"What you say may be very true, but this is my way of thinking." A small acquaintance with the world will show you instances of the most absurd and foolish conduct in persons of brilliant parts and entertaining faculties. But how trifling is the talent of diverting an idle hour, compared with true wisdom and prudence, which are perpetually wanted to direct us safely and happily through life, and to make us useful and valuable to others!

Fancy, I know, will have her share in friendship, as well as in love:—you must please as well as serve me, before I can love you as the friend of my heart. But the faculties that please for an evening may not please for life. The humourous man soon runs through his stock of odd stories, mimickry, and jest; and the wit, by constant repeated flashes, confounds and tires one's intellect, instead of enlivening it with agreeable surprise: but good sense can neither tire nor wear out; it improves by exercise, and increases in value, the more it is known: the pleasure it gives in conversation is lasting and satisfactory, because it is accompanied with improvement; its worth is proportioned to the occasion that calls for it, and rises highest on the most interesting topics; the heart, as well as the understanding, finds its account in it; and our noblest interests are promoted by the entertainment we receive from such a companion.

A good temper is the next qualification; the value of which in a friend, you will want no arguments to prove, when you are truly convinced of the necessity of it in yourself, which I shall endeavour to show you in a following letter. But, as this is a quality in which you may be deceived, without a long and intimate acquaintance, you must not be hasty in forming connections, before you have had sufficient opportunity for making observations on this head. A young person, when pleased and enlivened by the presence of her youthful companions, seldom shows ill temper; which must be extreme indeed, if it is not at least controllable in such situations. But, you must watch her behaviour to her own family, and the degree of estimation she stands in with them. Observe her manner to servants and inferiors—to children—and even to animals. See in what manner she bears disappointments, contradiction, and restraint; and what degree of vexation she expresses on any accident of loss or trouble. If in such little trials she shows a meek, resigned, and cheerful temper, she will probably preserve it on greater occasions; but if she is impatient and discontented under these, how will she support the far greater evils which may await her in her progress through life? If you should have an opportunity of seeing her in sickness, observe whether her complaints are of a mild and gentle kind, forced from her by pain, and restrained as much as possible; or whether they are expressions of a turbulent rebellious mind, that hardly submits to the Divine hand. See whether she is tractable, considerate, kind, and grateful, to those about her: or whether she takes the opportunity, which their compassion gives her, to tyrannize over and torment them. Women are in general very liable to ill health, which must necessarily make them in some measure troublesome and disagreeable to those they live with. They should therefore, take the more pains to lighten the burden as much as possible, by patience and good humour; and be careful not to let their infirmities break in on the health, freedom, or enjoyments of others, more than is needful and just. Some ladies seem to think it very improper for any person within their reach to enjoy a moment's comfort while they are in pain; and make no scruple of sacrificing to their own least convenience, whenever they are indisposed, the proper rest, meals, or refreshments of their servants, and even sometimes of their husbands and children. But their selfishness defeats its own purpose, as it weakens that affection and tender pity which excites the most assiduous services, and affords the most healing balm to the heart of the sufferer.

I have already expressed my wishes that your chosen friend may be some years older than yourself; but this is an advantage not always to be obtained. Whatever be her age, religion, discretion, good sense, and good temper, must on no account be dispensed with; and till you can find one so qualified, you had better make no closer connection than that of a mutual intercourse of civilities and good offices. But if it is always your aim to mix with the best company, and to be worthy of such society, you will probably meet with some one among them deserving your affection, to whom you may be equally agreeable.
