Of Slavery

22. The Natural Liberty of Man is to be free from any Superior Power on Earth, and not be under the Will or Legislative Authority of Man, but to have only the Law of Nature for his Rule. The Liberty of Man, in Society, is to be under no other Legislative Power, but that established by consent, in the Common-wealth, nor but what the Dominion of any Will, or Restraint of any Law, but what the Legislative shall enact, according to the Trust put in it. Freedom then is not what Sir R. F. tells us, O. A. 55 [224]. A Liberty for every one to do what he lists, to live as he pleases, and not to be tyed by any Laws: But Freedom of Men under Government, is, to have a standing Rule to live by, common to every one of that Society, and made by the Legislative Power erected in it; A Liberty to follow my own Will in all things, where the Rule prescribes not; and not to be subject to the inconstant, uncertain, unknown, Arbitrary Will of another Man. As Freedom of Nature is to be under no other restraint buy the Law of Nature.

23. This Freedom from Absolute, Arbitrary Power, is so necessary to, and closely joined with a Man’s Preservation, that he cannot part with it, but by what forfeits his Preservation and Life together. For a Man, not having the Power of his own Life, cannot, by Compact, or his own Consent, enslave himself to any one, nor put himself under the absolute, Arbitrary Power of another, to take away his Life, when he pleases. No body can give more Power than he has himself; and he cannot take away his own Life, cannot give another power over it. Indeed having, by his fault, forfeited his own Life, by some Act that deserved Death; he, to whom he has forfeited it, may (when he has him in his Power) delay to take it, and make use of him to his own Service, and he does him no injury by it. For, whenever he finds the hardship of his Slavery out-weigh the value of his Life, ‘tis in his Power, by resisting the Will of his Master, to draw on himself the Death he desires.

24. This is the perfect condition of Slavery, which is nothing else, but the State of War continued, between a lawful Conqueror, and a Captive. For, f once Compact enter between them, and make an arrangement for a limited Power on the one side, and Obedience on the other, the State of War and Slavery ceases, as long as the Compact endures. For, as has been said, no Man can, by agreement, pass over to another that which hath not in himself, a Power over his own Life.
