Rudolf von Jhering, The Struggle for Law — Chapter I (1872)
“ All the law in the world has been obtained by strife. Every principle of law which obtains had first to be wrung by force from those who denied it; and every legal right—the legal rights of a whole nation as well as those of individuals—supposes a continual readiness to assert it and defend it. The law is not mere theory, but living force. And hence it is that Justice which, in one hand, holds the scales, in which she weighs the right, carries in the other the sword with which she executes it. The sword without the scales is brute force, the scales without the sword is the impotence of law. ”
