If a covenant be made, wherein neither of the parties perform presently, but trust one another; in the condition of mere nature, which is a condition of war of every man against every man, upon any reasonable suspicion, it is void: but if there be a common power set over them both, with right and force sufficient to compel performance, it is not void. For he that performeth first, has no assurance the other will perform after; because the bonds of words are too weak to bridle men’s ambition, avarice, anger, and other passions, without the fear of some coercive power; which in the condition of mere nature, where all men are equal, and judges of the justness of their own fears, cannot possibly be supposed. And therefore he which performeth first, does but betray himself to his enemy; contrary to the right, he can never abandon, of defending his life, and means of living. But in a civil estate, where there is a power set up to constrain those that would otherwise violate their faith, that fear is no more reasonable; and for that cause, he which by the covenant is to perform first, is obliged so to do. The cause of fear, which maketh such a covenant invalid, must be always something arising after the covenant made; as some new fact, or other sign of the will not to perform: else it cannot make the covenant void. For that which could not hinder a man from promising, ought not to be admitted as a hindrance of performing. [Sidenote: Right to the end, containeth right to the means.] He that transferreth any right, transferreth the means of enjoying it, as far as lieth in his power. As he that selleth land, is understood to transfer the herbage, and whatsoever grows upon it: nor can he that sells a mill turn away the stream that drives it. And they that give to a man the right of government in sovereignty, are understood to give him the right of levying money to maintain soldiers; and of appointing magistrates for the administration of justice. [Sidenote: No covenant with beasts.] To make covenants with brute beasts, is impossible; because not understanding our speech, they understand not, nor accept of any translation of right; nor can translate any right to another: and without mutual acceptation, there is no covenant. [Sidenote: Nor with God without special revelation.] To make covenant with God, is impossible, but by mediation of such as God speaketh to, either by revelation supernatural, or by his lieutenants that govern under him, and in his name: for otherwise we know not whether our covenants be accepted, or not. And therefore they that vow anything contrary to any law of nature, vow in vain; as being a thing unjust to pay such vow. And if it be a thing commanded by the law of nature, it is not the vow, but the law that binds them. [Sidenote: No covenant, but of possible and future.]
