We hear a lot about the Ten Commandments, particularly in some of the southern states where large numbers of people live in extreme poverty. A lot of political action has been devoted to whether or not it is consistent with the U. S. Constitution for the Ten Commandments to be displayed in or near our courthouses.

Henry George: The Condition of Labor — An Open Letter to Pope Leo XIII in response to Rerum Novarum (1891)

As to the use of land, we hold: That —

While the right of ownership that justly attaches to things produced by labor cannot attach to land, there may attach to land a right of possession. As your Holiness says, “God has not granted the earth to mankind in general in the sense that all without distinction can deal with it as they please,” and regulations necessary for its best use may be fixed by human laws. But such regulations must conform to the moral law — must secure to all equal participation in the advantages of God’s general bounty. The principle is the same as where a human father leaves property equally to a number of children. Some of the things thus left may be incapable of common use or of specific division. Such things may properly be assigned to some of the children, but only under condition that the equality of benefit among them all be preserved.

In the rudest social state, while industry consists in hunting, fishing, and gathering the spontaneous fruits of the earth, private possession of land is not necessary. But as men begin to cultivate the ground and expend their labor in permanent works, private possession of the land on which labor is thus expended is needed to secure the right of property in the products of labor. For who would sow if not assured of the exclusive possession needed to enable him to reap? who would attach costly works to the soil without such exclusive possession of the soil as would enable him to secure the benefit?

This right of private possession in things created by God is however very different from the right of private ownership in things produced by labor. The one is limited, the other unlimited, save in cases when the dictate of self-preservation terminates all other rights. The purpose of the one, the exclusive possession of land, is merely to secure the other, the exclusive ownership of the products of labor; and it can never rightfully be carried so far as to impair or deny this. While any one may hold exclusive possession of land so far as it does not interfere with the equal rights of others, he can rightfully hold it no further.

Thus Cain and Abel, were there only two men on earth, might by agreement divide the earth between them. Under this compact each might claim exclusive right to his share as against the other. But neither could rightfully continue such claim against the next man born. For since no one comes into the world without God’s permission, his presence attests his equal right to the use of God’s bounty. For them to refuse him any use of the earth which they had divided between them would therefore be for them to commit murder. And for them to refuse him any use of the earth, unless by laboring for them or by giving them part of the products of his labor he bought it of them, would be for them to commit theft. ... read the whole letter

Henry George: The Single Tax: What It Is and Why We Urge It (1890)

From the Single Tax we may expect these advantages: ...

The right of property does not rest upon human laws; they have often ignored and violated it. It rests on natural laws -- that is to say, the law of God. It is clear and absolute, and every violation of it, whether committed by a man or a nation, is a violation of the command, "Thou shalt not steal."

The man who catches a fish, grows an apple, raises a calf, builds a house, makes a coat, paints a picture, constructs a machine, has, as to any such thing, an exclusive right of ownership which carries with it the right to give, to sell or bequeath that thing.
