Rudolf von Jhering, The Struggle for Law — Chapter V (1872)
“ Law is idealism—paradoxical as this may seem—not the idealism of the fancy, but of character: that is, of the man who looks upon himself as his own end, and esteems all else lightly when he is attacked in his personality. What matters it to him whence this attack upon his rights proceeds—whether from an individual, from his own government, or from a foreign nation? It is not the person of the aggressor that decides what resistance he shall oppose to the attack, but the energy of his feeling of legal right, the moral force with which he is wont to assert himself. ”
