The obligation of subjects to the sovereign is understood to last as long, and no longer, than the power lasteth by which he is able to protect them. For the right men have by nature to protect themselves, when none else can protect them, can by no covenant be relinquished. The sovereignty is the soul of the commonwealth, which once departed from the body, the members do no more receive their motion from it. The end of obedience is protection, which, wheresoever a man seeth it, either in his own or in another’s sword, nature applieth his obedience to it, and his endeavour to maintain it. And though sovereignty, in the intention of them that make it, be immortal, yet is it in its own nature not only subject to violent death by foreign war, but also, through the ignorance and passions of men, it hath in it, from the very institution, many seeds of a natural mortality, by intestine discord.
