John Locke. (№ 433715)

Although the earth and all the lower beings belong together to all people, yet each person has some property, which is contained in his own personality, to which no one but himself has any rights. We can say that the labor of his body and the labor of his hands are, in the strictest terms, his. Whatever then a person takes from the state in which nature has created and preserved this object, he combines it with his labor and attaches to it something belonging to him personally and thereby makes it his property. Since he takes this object out of the state of common possession in which nature has placed it, then, thanks to his labor, he attaches something to it that excludes the common law of other people. Indeed, since this labor is the indisputable property of the worker, not a single person, except him, can have the right to what he once attached it to, at least in those cases when a sufficient amount of the same quality [of the object of labor] remains for the general use of others.
