But, though the evidence does not warrant our going so far as this, it renders less presumptuous the conjecture that private property, in the shape in which we know it, was chiefly formed by the gradual disentanglement of the separate rights of individuals from the blended rights of a community. Our studies in the Law of Persons seemed to show us the Family expanding into the Agnatic group of kinsmen, then the Agnatic group dissolving into separate households; lastly the household supplanted by the individual; and it is now suggested that each step in the change corresponds to an analogous alteration in the nature of Ownership. If there be any truth in the suggestion, it is to be observed that it materially affects the problem which theorists on the origin of Property have generally proposed to themselves. The question--perhaps an insoluble one--which they have mostly agitated is, what were the motives which first induced men to respect each other's possessions? It may still be put, without much hope of finding an answer to it, in the form of any inquiry into the reasons which led one composite group to keep aloof from the domain of another. But, if it be true that far the most important passage in the history of Private Property is its gradual elimination from the co-ownership of kinsmen, then the great point of inquiry is identical with that which lies on the threshold of all historical law--what were the motives which originally prompted men to hold together in the family union? To such a question, Jurisprudence, unassisted by other sciences, is not competent to give a reply. The fact can only be noted.
