"[A] republic . . . [is] a government, in which the property of the public, or people, and of every one of them was secure and protected by law . . . implies liberty; because property cannot be secured unless the man be at liberty to acquire, use or part with it, at his discretion, and unless he have his personal liberty of life and limb, motion and rest, for that purpose."

The value of any commodity, therefore, to the person who possesses it, and who means not to use or consume it himself, but to exchange it for other commodities, is equal to the quantity of labour which it enables him to purchase or command. Labour, therefore, is the real measure of the exchangeable value of all commodities. The real price of everything, what everything really costs to the man who wants to acquire it, is the toil and trouble of acquiring it.
