*54* Suppose again that an honest man is offering a house for sale on account of certain undesirable features of which he himself is aware but which nobody else knows; suppose it is unsanitary, but has the reputation of being healthful; suppose it is not generally known that vermin are to be found in all the bedrooms; suppose, finally, that it is built of unsound timber and likely to collapse, but that no one knows about it except the owner; if the vendor does not tell the purchaser these facts but sells him the house for far more than he could reasonably have expected to get for it, I ask whether his transaction is unjust or dishonourable. *55* "Yes," says Antipater, "it is; for to allow a purchaser to be hasty in closing a deal and through mistaken judgment to incur a very serious loss, if this is not refusing 'to set a man right when he has lost his way' (a crime which at Athens is prohibited on pain of public execration), what is? It is even worse than refusing to set a man on his way: it is deliberately leading a man astray." *(55)* "Can you say," answers Diogenes, "that he compelled you to purchase, when he did not even advise it? He advertised for sale what he did not like; you bought what you did like. If people are not considered guilty of swindling when they place upon their placards FOR SALE: A FINE VILLA, WELL BUILT, even when it is neither good nor properly built, still less guilty are they who say nothing in praise of their house. For where the purchaser may exercise his own judgment, what fraud can there be on the part of the vendor? But if, again, not all that is expressly stated has to be made good, do you think a man is bound to make good what has not been said? What, pray, would be more stupid than for a vendor to recount all the faults in the article he is offering for sale? And what would be so absurd as for an auctioneer to cry, at the owner's bidding, 'Here is an unsanitary house for sale?'"
