1. It is a common saying that nature maketh nothing in vain. And it is most certain, that as the truth of a conclusion, is no more but the truth of the premises that make it; so the force of the command, or law of nature, is no more than the force of the reasons inducing thereunto. Therefore the law of nature mentioned in the former chapter, section 2, namely, _That every man should divest himself of the right_, &c. were utterly vain, and of none effect, if this also were not a law of the same nature, _That every man is obliged to stand to, and perform, those covenants he maketh_. For what benefit is it to a man, that any thing be promised, or given unto him, if he that giveth, or promiseth, performeth not, or retaineth still the right of taking back what he hath given? [Sidenote: Injury defined.] 2. The breach or violation of covenant, is that which men call _injury_, consisting in some action or omission, which is therefore called _unjust_. For it is action or omission, without _jus_, or right, which was transferred or relinquished before. There is a great similitude between that we call _injury_, or _injustice_ in the actions and conversations of men in the world, and that which is called _absurd_ in the arguments and disputations of the Schools. For as he, which is driven to contradict an assertion by him before maintained, is said to be reduced to an absurdity; so he that through passion doth, or omitteth that which before by covenant he promised to do, or not to omit, is said to commit injustice; and there is in every breach of covenant a contradiction properly so called. For he that covenanteth, willeth to do, or omit, in the time to come. And he that doth any action, willeth it in that present, which is part of the future time contained in the covenant. And therefore he that violateth a covenant, willeth the doing and the not doing of the same thing, at the same time, which is a plain contradiction. And so _injury_ is an _absurdity_ of conversation, as absurdity is a kind of injustice in disputation. [Sidenote: That injury is done only to the covenantee.] 3. In all violation of covenant, (to whomsoever accrueth the damage) the injury is done only to him to whom the covenant was made. For example, if a man covenant to obey his master, and the master command him to give money to a third, which he promiseth to do, and doth not, though this be to the damage of the third, yet the injury is done to the master only. For he could violate no covenant with him, with whom none was made, and therefore doth him no injury. For injury consisteth in violation of covenant by the definition thereof.
