The only criticism which could be directly applied to the theory of Blackstone would consist in inquiring whether the circumstances which make up his picture of a primitive society are more or less probable than other incidents which could be imagined with equal readiness. Pursuing this method of examination, we might fairly ask whether the man who had _occupied_ (Blackstone evidently uses this word with its ordinary English meaning) a particular spot of ground for rest or shade would be permitted to retain it without disturbance. The chances surely are that his right to possession would be exactly coextensive with his power to keep it, and that he would be constantly liable to disturbance by the first comer who coveted the spot and thought himself strong enough to drive away the possessor. But the truth is that all such cavil at these positions is perfectly idle from the very baselessness of the positions themselves. What mankind did in the primitive state may not be a hopeless subject of inquiry, but of their motives for doing it it is impossible to know anything. These sketches of the plight of human beings in the first ages of the world are effected by first supposing mankind to be divested of a great part of the circumstances by which they are now surrounded, and by then assuming that, in the condition thus imagined, they would preserve the same sentiments and prejudices by which they are now actuated,--although, in fact, these sentiments may have been created and engendered by those very circumstances of which, by the hypothesis, they are to be stripped.
