In other words, a maxim to this effect--were it to become law - that any object on which the will can be exerted must remain objectively in itself without an owner, as res nullius, is contrary to the principle of right.An object of my free will, however, is one which I have the physical capability of making some use of at will, since its use stands in my power (in potentia).For an object of any act of my will, is something that it would be physically within my power to use.
