Nobody loves this sort of people; no one shows them more than the commonest civility, and scarcely that; and this frequently puts them out of humour, and draws them into disputes. If they aim at obtaining any advantage in rank or fortune, nobody wishes them success, or will stir a step to favour 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 poor gentlemen will not change this bad habit, condescend to be pleased with what is pleasing, without fretting themselves and others about the contraries, it is good 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 was grown, from experience, 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, kept his eyes on his ugly leg more than the handsome one, he doubted him; if he spoke of it, and 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, fault-finding disposition, and take the same resolution of avoiding the acquaintance of those infected with it. I therefore advise those critical, querulous, discontented, unhappy people, that if they wish to be respected and beloved by others, and happy in themselves, they should _leave off looking at the ugly leg_. "_A good wit will turn every thing to advantage_," says Shakespeare; and the following will show what a singular passion Dr. Franklin had to turn every little cross incident of his own life into pleasure and profit to others. He calls it STOOP, AND GO SAFE. _To the late Dr. Mather, of Boston._ REV. SIR, When I was a boy, I met with a book, entitled, "_Essays to do good_," which, I think, was written by your father. It had been so little regarded by a former possessor, that several leaves of it were torn out: but the remainder gave me such a turn for thinking, as to have an influence on my conduct through life; for I have always set a greater value on the character of a doer of good than any other kind of reputation; and if I have been, as you seem to think, a useful citizen, the public owes the advantage of it to that book.
