All law relations are determined by this principle: each one must restrict his freedom by the possibility of the freedom of the other. ... My freedom is limited by the freedom of the other only on condition that he limits his freedom by the conception of mine. Otherwise he is lawless. Hence, if a law-relation is to result from my cognition of the other, the cognition and the consequent limitation of freedom must have been mutual. All law-relation between persons is, therefore, conditioned by their mutual cognition of each other, and is, at the same time, completely determined thereby.
