Again, the injustice of manners, is the disposition, or aptitude to do injury; and is injustice before it proceed to act; and without supposing any individual person injured. But the injustice of an action, that is to say injury, supposeth an individual person injured; namely him, to whom the covenant was made: and therefore many times the injury is received by one man, when the damage redoundeth to another. As when the master commandeth his servant to give money to a stranger; if it be not done, the injury is done to the master, whom he had before covenanted to obey; but the damage redoundeth to the stranger, to whom he had no obligation; and therefore could not injure him. And so also in commonwealths, private men may remit to one another their debts; but not robberies or other violences, whereby they are endamaged; because the detaining of debt, is an injury to themselves; but robbery and violence, are injuries to the person of the commonwealth. [Sidenote: Nothing done to a man by his own consent can be injury.] Whatsoever is done to a man, conformable to his own will signified to the doer, is no injury to him. For if he that doeth it, hath not passed away his original right to do what he please, by some antecedent covenant, there is no breach of covenant; and therefore no injury done him. And if he have; then his will to have it done being signified, is a release of that covenant: and so again there is no injury done him. [Sidenote: Justice commutative and distributive.] Justice of actions, is by writers divided into _commutative_, and _distributive_: and the former they say consisteth in proportion arithmetical; the latter in proportion geometrical. Commutative therefore, they place in the equality of value of the things contracted for; and distributive, in the distribution of equal benefit, to men of equal merit. As if it were injustice to sell dearer than we buy; or to give more to a man than he merits. The value of all things contracted for, is measured by the appetite of the contractors: and therefore the just value, is that which they be contented to give. And merit, besides that which is by covenant, where the performance on one part, meriteth the performance of the other part, and falls under justice commutative, not distributive, is not due by justice; but is rewarded of grace only. And therefore this distinction, in the sense wherein it useth to be expounded, is not right. To speak properly, commutative justice, is the justice, of a contractor; that is, a performance of covenant, in buying, and selling; hiring, and letting to hire; lending, and borrowing; exchanging, bartering, and other acts of contract.
