He who boasts of being perfect is perfect in folly. I have been a good deal up and down the world, and I never did see either a perfect horse or a perfect man, and I never shall till two Sundays come together. You cannot get white flour out of a coal sack nor perfection out of human nature; he who looks for it had better look for sugar in the sea. The old saying is, "Lifeless, faultless About dead men we should say nothing but good“; but as for the living, they are all tarred more or less with the black brush, and half an eye can see it. Every head has a soft place in it, and every heart has its black drop. Every rose has its prickles, and every day its night. Even the sun shows spots, and the skies are darkened with clouds. Nobody is so wise but he has folly enough to stock a stall at Vanity Fair. Where I could not see the fool's cap, I have nevertheless heard the bells jingle. As there is no sunshine without some shadows, so is all human good mixed up with more or less of evil. Even poor law guardians have their little failings, and parish beadles are not wholly of heavenly nature. The best wine has its dregs. All men's faults are not written on their foreheads, and it's quite as well they are not, or hats would need very wide brims. Yet, as sure as eggs are eggs, faults of some sort nestle in every bosom. There's no telling when a man's sins may show themselves, for hares pop out of the ditch just when you are not looking for them. A horse that is weak in the legs may not stumble for a mile or two, but it is in him, and the rider had better hold him up well. The tabby cat is not lapping milk just now, but leave the dairy door open, and we will see if she is not as bad a thief as the kitten. There's fire in the flint, cool as it looks: wait till the steel gets a knock at it, and you will see. Everybody can read that riddle, but it is not everybody that will remember to keep his gunpowder out of the way of the candle.
If we would always recollect that we live among men who are imperfect, we should not be in such a fever when we find out our friends' failings. What's rotten will rend, and cracked pots will leak. Blessed is he who expects nothing of poor flesh and blood, for he shall never be disappointed. The best of men are men at best, and the best wax will melt.
It is a good horse that never stumbles,
And a good wife that never grumbles.
But surely such horses and wives are only found in the fool's paradise, where dumplings grow on trees. In this wicked world the straightest timber has knots in it, and the cleanest field of wheat has its share of weeds. The most careful driver one day upsets the cart; the cleverest cook spills a little broth; and as I know to my sorrow a very decent plowman will now and then break the plow and often make a crooked furrow. It is foolish to turn off a tried friend because of a failing or two, for you may get rid of a one-eyed nag and buy a blind one. Being all of us full of faults, we ought to keep two bears, and learn to bear and forbear with one another. Since we all live in glass houses, we should none of us throw stones. Everybody laughs when the saucepan says to the kettle, "How black you are!" Other men's imperfections show us our imperfection for one sheep is much like another; and if there's an speck in my neighbor's eye, there is no doubt one in mine. We ought to use our neighbors as mirrors to see our own faults in, and mend in ourselves what we see in them.
I have no patience with those who poke their noses into every man's house to smell out his faults, and put on magnifying glasses to discover their neighbors' flaws. Such folks had better look at home; they might see the devil where they little expected. What we wish to see, we shall see or think we see. Faults are always thick where love is thin. A white cow is all black if your eye chooses to make it so. If we sniff long enough at rose water, we shall find out that it has a bad smell. It would be a far more pleasant business, at least for other people, if fault-finders would turn their dogs to hunt out the good points in other folks; the game would pay better, and nobody would stand with a pitchfork to keep the hunters off his farm. As for our own faults, it would take a large slate to hold the account of them; but, thank God, we know where to take them and how to get the better of them. With all our faults, God loves us still if we are trusting in His Son. Therefore, let us not be downhearted, but hope to live and learn and do some good service before we die. Though the cart creaks, it will get home with its load, and the old horse, broken-kneed as he is, will do a sight of work yet. There's no use in lying down and doing nothing because we cannot do everything as we should like. Faults or no faults, plowing must be done; imperfect people must do it, too, or there will be no harvest next year. Bad plowman as John may be, the angels won't do his work for him, and so he is off to do it himself. Go along, Violet! Gee, whoa! Dapper!
