I occupy a piece of land; the presumption is, that I am the proprietor, until the contrary is proved.

We know that originally such a right cannot be legitimate unless it is reciprocal; the jurists say as much.
Cicero compares the earth to a vast theatre: _Quemadmodum theatrum cum commune sit, recte tamen dici potest ejus esse eum locum quem quisque occuparit_.
This passage is all that ancient philosophy has to say about the origin of property.
The theatre, says Cicero, is common to all; nevertheless, the place that each one occupies is called HIS OWN; that is, it is a place POSSESSED, not a place APPROPRIATED.

This comparison annihilates property; moreover, it implies equality.

Can I, in a theatre, occupy at the same time one place in the pit, another in the boxes, and a third in the gallery?
Not unless I have three bodies, like Geryon, or can exist in different places at the same time, as is related of the magician Apollonius.
According to Cicero, no one has a right to more than he needs: such is the true interpretation of his famous axiom--_suum quidque cujusque sit_, to each one that which belongs to him--an axiom that has been strangely applied.

That which belongs to each is not that which each MAY possess, but that which each HAS A RIGHT to possess.
