Thus, labor gives birth to private possession; the right in a thing--jus in re. But in what thing? Evidently IN THE PRODUCT, not IN THE SOIL. So the Arabs have always understood it; and so, according to Caesar and Tacitus, the Germans formerly held. "The Arabs," says M. de Sismondi, "who admit a man's property in the flocks which he has raised, do not refuse the crop to him who planted the seed; but they do not see why another, his equal, should not have a right to plant in his turn. The inequality which results from the pretended right of the first occupant seems to them to be based on no principle of justice; and when all the land falls into the hands of a certain number of inhabitants, there results a monopoly in their favor against the rest of the nation, to which they do not wish to submit." Well, they have shared the land. I admit that therefrom results a more powerful organization of labor; and that this method of distribution, fixed and durable, is advantageous to production: but how could this division give to each a transferable right of property in a thing to which all had an inalienable right of possession? In the terms of jurisprudence, this metamorphosis from possessor to proprietor is legally impossible; it implies in the jurisdiction of the courts the union of possessoire and petitoire; and the mutual concessions of those who share the land are nothing less than traffic in natural rights. The original cultivators of the land, who were also the original makers of the law, were not as learned as our legislators, I admit; and had they been, they could not have done worse: they did not foresee the consequences of the transformation of the right of private possession into the right of absolute property. But why have not those, who in later times have established the distinction between jus in re and jus ad rem, applied it to the principle of property itself? Let me call the attention of the writers on jurisprudence to their own maxims. The right of property, provided it can have a cause, can have but one--_Dominium non potest nisi ex una causa contingere_. I can possess by several titles; I can become proprietor by only one--_Non ut ex pluribus causis idem nobis deberi potest, ita ex pluribus causis idem potest nostrum esse_. The field which I have cleared, which I cultivate, on which I have built my house, which supports myself, my family, and my livestock, I can possess: 1st. As the original occupant; 2d. As a laborer; 3d. By virtue of the social contract which assigns it to me as my share.
