In whatever situation men can be placed, they may find conveniences and inconveniencies; in whatever company, they may find persons and conversation more or less pleasing; at whatever table, they may meet with meats or drinks of better and worse taste, dishes better or worse dressed; in whatever climate they will find good and bad weather; under whatever government, they may find good and bad laws, and good and bad administration of those laws; in every poem or work of genius they may see faults and beauties; in almost every face and every person, they may discover fine features and effects, good and bad qualities. Under these circumstances, the two kinds of people above mentioned fix their attention, those who are to be happy, on the conveniences of things, the pleasant parts of conversation, the well-dressed dishes, the goodness of the wines, the fine weather, and enjoy all with cheerfulness. Those who are to be unhappy, think and speak only of the contraries. Hence they are continually discontented themselves, and by their remarks sour the pleasures of society, offend personally many people, and make themselves everywhere disagreeable. If this turn of mind were founded in nature, such unhappy persons would be the more to be pitied. The tendency to criticize and to be disgusted is perhaps taken up originally by imitation, and is unawares grown into a habit, which at present strong may nevertheless be cured when those who have it are convinced of its bad effects on their felicity. I hope this little admonition may be of service to them, and put them on changing a habit, which in the exercise is chiefly an act of imagination yet has serious consequences in life, as it brings on real grieves and misfortunes. For many are offended, nobody loves this sort of people, no one shows them more than the most common civility and respect, and scarcely that; and this frequently puts them out of humor, and draws them into disputes and contentions. If they aim at obtaining some advantage in rank or fortune, nobody wishes them success, or will stir a step, or speak a word, to favor their pretensions. If they incur public censure or disgrace, no one will defend or excuse, and many join to aggravate their misconduct, and render them completely odious. If these people will not change this bad habit, and condescend to be pleased with what is pleasing, without fretting themselves and others about the contraries, it is good for others to avoid an acquaintance with them, which is always disagreeable, and sometimes very inconvenient, especially when one finds one's self entangled in their quarrels. An old philosophical friend of mine grown from experience, was very cautious in this particular, and carefully avoided any intimacy with such people. He had, like other philosophers, a thermometer to show him the heat of the weather, and a barometer to mark when it was likely to prove good or bad; but, there being no instrument invented to discover, at first sight, this unpleasing disposition in a person. He for that purpose made use of his legs, one of which was remarkably handsome, the other, by some accident, crooked and deformed. If a stranger, at the first interview, regarded his ugly leg more than his handsome one, he doubted him. If he spoke of it, took no notice of the handsome leg, that was sufficient to determine my philosopher to have no further acquaintance with him. Every body has not this two-legged instrument, but every one with a little attention, may observe signs of that carping, faultfinding disposition, and take the same resolution of avoiding the acquaintance of those infected with it. I therefore advise those critical, querulous, dis A．their comforts of life B．their minds C．their feelings D．their health and wealth
