how the vague circumference of the notion of duty shrinks and at the same time grows more precise when we wash it with cynical acid and expel everything except the object of our study, the operations of the law.
Nowhere is the confusion between legal and moral ideas more manifest than in the law of contract. Among other things, here again the so called primary rights and duties are invested with a mystic significance beyond what can be assigned and explained. The duty to keep a contract at common law means a prediction that you must pay damages if you do not keep it,—and nothing else. If you commit a tort, you are liable to pay a compensatory sum. If you commit a contract, you are liable to pay a compensatory sum unless the promised event comes to pass, and that is all the difference. But such a mode of looking at the matter stinks in the nostrils of those who think it advantageous to get as much ethics into the law as they can. It was good enough for Lord Coke, however, and here, as in many other cases, I am content to abide with him. In Bromage v. Genning,[1] a prohibition was sought in the King's Bench against a suit in the marches of Wales for the specific performance of a covenant to grant a lease, and Coke said that it would subvert the intention of the covenantor, since he intends it to be at his election either to lose the damages or to make the lease. Sergeant Harris for the plaintiff confessed that he moved the matter against his conscience, and a prohibition was granted. This goes further than we should go now, but it shows what I venture to say has been the common law point of view from the beginning, although Mr. Harriman, in his very able little book upon Contracts has been misled, as I humbly think, to a different conclusion.
I have spoken only of the common law, because there are some cases in which a logical justification can be found for speaking of civil liabilities as imposing duties in an intelligible sense. These are the relatively few in which equity will grant an injunction, and will enforce it by putting the defendant in prison or otherwise punishing him unless he complies with the order of the court. But I hardly think it advisable to shape general theory from the exception, and I think it would be better to cease troubling ourselves about primary rights and sanctions altogether, than to
