_Quest._ V. Is it lawful to make a thing seem better than it is, by trimming, adorning, or setting the best side outward or in sight; or to conceal the faults of what I am to sell? _Answ._ It is lawful to dress, polish, adorn, or set out your commodity, to make it seem as it is indeed, but not to make it seem better than it is: except in some very few unusual cases; as if you deal with some fantastical fool, who will not buy it, nor give you the true worth, except it be so set out, and made in some respects to seem better than it is. It is lawful so far to serve their curiosity or humour, as to get the worth of your commodity. But if you do it to get more than the worth by deceiving, it is a sin. And such glossing hath so notable an appearance of deceit, that for that scandal it should be avoided. 2. And as for concealing the fault, the case is the same; you ought not to deceive your neighbour, but to do as you would be done by; and therefore must not conceal any fault which he desireth or is concerned to know. Except it be when you deal with one who maketh a far greater matter of that fault than there is cause, and would wrong you in the price if it were known: yea, and that exception will not hold neither, except in a case when you must needs sell, and they must buy it: because, 1. You may not have another man's money against his will, though it be no more than the thing is worth. 2. Because it will be scandalous when the fault is known by him that buyeth it. _Quest._ VI. What if the fault was concealed from me when I bought it, or if I were deceived or over-reached by him that sold it me, and gave more than the worth, may I not repair my loss by doing as I was done by? _Answ._ No: no more than you may cut another's purse, because yours was cut; you must do as you would be done by, and not as you are done by. What you may do with the man that deceived you, is a harder question; but doubtless you may not wrong an honest man, because you were wronged by a knave. _Object._ But it is taken for granted in the market, that every man will get as much as he can have, and that _caveat emptor_ is the only security; and therefore every man trusteth to his own wit, and not to the seller's honesty, and so resolveth to run the hazard.
