Private property does not historically come into existence by any means as a rule as the product of robbery and violence. On the contrary. It arises from the limitation of certain things in the early tribal communes. It develops in the first place within the tribe and afterwards in exchange with peoples outside of the tribe in the form of wares. In proportion as the products of the tribe assume the form of commodities, i.e., the less they are produced for the use of the producer and the more for the purpose of exchange, the exchange destroys the original form of distribution in the commune itself, and the more unequal become the shares of the individual members of the community with respect to material possessions. So the old communal ownership of land becomes more and more invaded, the communal property is rapidly converted into a village of farmers, each tilling his own piece of ground. Oriental despotism and the changing government of conquering nomads had no power to alter the old form of communal ownership for a thousand years. But the continual destruction of the primitive domestic industry through the competition of the products of the great industry is bringing about its dissolution. The thing has little to do with force as has lately appeared in the matter of the division of the communal property of the feudal societies on the Moselle and in Hochwald. The peasants are finding the substitution of individual for communal holdings to their interests. Even the growth of a primitive aristocracy as among the Celts, the Germans, and in Mesopotamia, is a result of the communal ownership of landed property, and does not depend upon force in the slightest degree but upon free will and custom. Especially where private property arises it appears as the result of a change in the methods of production and exchange in the interests of the increase of production and the development of commerce and therefore arises from economic causes. Force plays no role in this. It is clear that the institution of private property must have already existed before the robber is able to possess himself of other people's goods and that force may change the possession but cannot alter private property as such.
