When the actor doth anything against the law of Nature by command of the author, if he be obliged by former covenant to obey him, not he but the author breaketh the law of Nature; for though the action be against the law of Nature, yet it is not his: but contrarily, to refuse to do it, is against the law of Nature, that forbiddeth breach of covenant.

And he that maketh a covenant with the author by mediation of the actor, not knowing what authority he hath, but only takes his word, in case such authority be not made manifest unto him upon demand, is no longer obliged, for the covenant made with the author is not valid without his counter-assurance. But if he that so covenanteth knew beforehand he was to expect no other assurance than the actor’s word, then is the covenant valid, because the actor in this case maketh himself the author. And therefore, as when the authority is evident, the covenant obligeth the author, not the actor; so when the authority is feigned, it obligeth the actor only, there being no author but himself.
