The idea of property arises out of the combative instincts of the species. Long before men were men, the ancestral ape was a proprietor. Primitive property is what a beast will fight for. The dog and his bone, the tigress and her lair, the roaring stag and his herd, these are proprietorship blazing. No more nonsensical expression is conceivable in sociology than the term “primitive communism.” The Old Man of the family tribe of early palæolithic times insisted upon his proprietorship in his wives and daughters, in his tools, in his visible universe. If any other man wandered into his visible universe he fought him, and if he could he slew him. The tribe grew in the course of ages, as Atkinson showed convincingly in his _Primal Law_, by the gradual toleration by the Old Man of the existence of the younger men, and of their proprietorship in the wives they captured from outside the tribe, and in the tools and ornaments they made and the game they slew. Human society grew by a compromise between this one’s property and that. It was a compromise with instinct which was forced upon men by the necessity of driving some other tribe out of its visible universe. If the hills and forests and streams were not _your_ land or _my_ land, it was because they had to be our land. Each of us would have preferred to have it _my_ land, but that would not work. In that case the other fellows would have destroyed us. Society, therefore, is from its beginning a _mitigation of ownership_. Ownership in the beast and in the primitive savage was far more intense a thing than it is in the civilized world to- day. It is rooted more strongly in our instincts than in our reason.
