Covenants entred into by fear, in the condition of meer Nature, are obligatory. For example, if I Covenant to pay a ransome, or service for my life, to an enemy; I am bound by it. For it is a Contract, wherein one receiveth the benefit of life; the other is to receive mony, or service for it; and consequently, where no other Law (as in the condition, of meer Nature) forbiddeth the performance, the Covenant is valid. Therefore Prisoners of warre, if trusted with the payment of their Ransome, are obliged to pay it; And if a weaker Prince, make a disadvantageous peace with a stronger, for feare; he is bound to keep it; unlesse (as hath been sayd before) there ariseth some new, and just cause of feare, to renew the war. And even in Common-wealths, if I be forced to redeem my selfe from a Theefe by promising him mony, I am bound to pay it, till the Civill Law discharge me. For whatsoever I may lawfully do without Obligation, the same I may lawfully Covenant to do through feare: and what I lawfully Covenant, I cannot lawfully break.
