He that breaks a promise, however solemnly made, may be an honest man, but he that makes a promise with a design to break it, or with no resolution of performing it, cannot be so: nay, to carry it farther, he that makes a promise, and does not do his endeavour to perform it, or to put himself into a condition to perform it, cannot be an honest man. A promise once made supposes the person willing to perform it, if it were in his power, and has a binding influence upon the person who made it, so far as his power extends, or that he can within the reach of any reasonable ability perform the conditions; but if it is not in his power to perform it, as in this affair of payment of money is often the case, the man cannot be condemned as dishonest, unless it can be made appear, either
1. That when he made the promise, he knew he should not be able to perform it; or,
2. That he resolved when he made the promise not to perform it, though he should be in a condition to do it. And in both these cases the morality of promising cannot be justified, any more than the immorality of not performing it.
But, on the other hand, the person promising, honestly intending when he made the appointment to perform it if possible, and endeavouring faithfully to be able, but being rendered unable by the disappointment of those on whose promises he depended for the performance of his own; I cannot say that such a tradesman can be charged with lying, or with any immorality in promising, for the breach was not properly his own, but the people’s on whom he depended; and this is justified from what I said before, namely, that every promise of that kind supposes the possibility of such a disappointment, even in the very nature of its making; for, if the man were not under a moral incapacity of payment, he would not promise at all, but pay at the time he promised. His promising, then, implies that he has only something future to depend upon, to capacitate him for the payment; that is to say, the appointments of payment by other tradesmen, who owe him (that promises) the money, or the daily supply from the ordinary course of his trade, suppose him a retailer in a shop, and the like; all which circumstances are subject to contingencies and disappointments, and are known to be so by the person to whom the promise is made; and it is with all those contingencies and possibilities of disappointment, that he takes or accepts the tradesman’s promise, and forbears him, in hopes that he will be able to perform, knowing, that unless he receives money as above, he cannot.
