The English cannot trade to Hungary, and into Slavonia--that is to say, they cannot do it to advantage; but it is better for them to trade to Venice with their goods, and let the Venetians carry on a trade into Hungary through Dalmatia, Croatia, &c, and the like in other places.
To bring it down to particular cases: one certain merchant cannot deal in one sort of goods which another merchant is eminent for; the other merchant is as free to the trade as he, but he cannot do it to profit; for he is unacquainted with the trade, and it is out of his way, and therefore he cannot do it.
Thus, to the case in hand.

The tradesman says he cannot sell his goods under such a price, which in the sense of his business is true; that is to say, he cannot do it to carry on his trade with the usual and reasonable advantage which he ought to expect, and which others make in the same way of business.
Or, he cannot, without underselling the market, and undervaluing the goods, and seeming to undersell his neighbour-shopkeepers, to whom there is a justice due in trade, which respects the price of sale; and to undersell is looked upon as an unfair kind of trading.
All these, and many more, are the reasons why a tradesman may be said not to lie, though he should say he _cannot_ abate, or _cannot_ sell his goods under such a price, and yet may after think fit to sell you his goods something lower than he so intended, or can afford to do, rather than lose your custom, or rather than lose the selling of his goods, and taking your ready money, which at that time he may have occasion for.
In these cases, I cannot say a shopkeeper should be tied down to the literal meaning of his words in the price he asks, or that he is guilty of lying in not adhering stiffly to the letter of his first demand; though, at the same time, I would have every tradesman take as little liberty that way as may be: and if the buyer would expect the tradesman should keep strictly to his demand, he should not stand and haggle, and screw the shopkeeper down, bidding from one penny to another, to a trifle within his price, so, as it were, to push him to the extremity, either to turn away his customer for a sixpence, or some such trifle, or to break his word: as if he would say, I will force you to speak falsely, or turn me away for a trifle.
In such cases, if, indeed, there is a breach, the sin is the buyer's: at least, he puts himself in the devil's stead, and makes himself both tempter and accuser; nor can I say that the seller is in that case so much to blame as the buyer.

However, it were to be wished that on both sides buying and selling might be carried on without it; for the buyer as often says, 'I won't give a farthing more,' and yet advances, as the seller says, 'I can't abate a farthing,' and yet complies.

These are, as I call them, _trading lies_; and it were to be wished they could be avoided on both sides; and the honest tradesman does avoid them as much as possible, but yet must not, I say, in all cases, be tied up to the strict, literal sense of that expression, _I cannot abate_, as above.[26] 2.

Another trading licence is that of appointing, and promising payments of money, which men in business are oftentimes forced to make, and forced to break, without any scrupple; nay, and without any reproach upon their integrity.
