undeceive v. 使某人不再抱幻想或不再受骗，醒悟
Only his sloppy communication failed to undeceive them in time.
Women have, in general, but one object, which is their beauty; upon which scarce any flattery is too gross for them to follow. Nature has hardly formed a woman ugly enough to be insensible to flattery upon her person; if her face is so shocking that she must, in some degree, be conscious of it, her face is so shocking that she must, in some degree, be conscious of it, her figure and air, she trusts, make ample amends for it. If they are both bad, she comforts herself that she has graces, a certain manner, a je ne sais quoi till more engaging than beauty. This truth is evident from the studied and elaborate dress of the ugliest woman in the world. An undoubted, uncontested, conscious beauty is of all women, the least sensible of flattery upon that head; she knows it is her due, and is therefore obliged to nobody for giving it her. She may possibly not doubt of herself, yet she suspects that men may distrust. ?Do not mistake me, and think that I mean to recommend to you abject and criminal flattery: no; flatter nobody's vices or crimes: on the contrary, abhor and discourage them. But there is no living in the world without a complaisant indulgence for people's weaknesses, and innocent, though ridiculous vanities. If a man has a mind to be thought wiser, and a woman handsomer, than they really are, their error is comfortable on to themselves, and ?an innocent one with regard to other people; and I would rather make them my friends by indulging them in it, than my enemies by endeavoring (and that to no purpose) to undeceive them.
