itself an absurd system if ever there was one, and contrary to the principles of natural right and to all good polity.
War then is a relation, not between man and man, but between State and State, and individuals are enemies only accidentally, not as men, nor even as citizens,[1] but as soldiers; not as members of their country, but as its defenders. Finally, each State can have for enemies only other States, and not men; for between things disparate in nature there can be no real relation.
Furthermore, this principle is in conformity with the established rules of all times and the constant practice of all civilised peoples. Declarations of war are intimations less to powers than to their subjects. The foreigner, whether king, individual, or people, who robs, kills or detains the subjects, without declaring war on the prince, is not an enemy, but a brigand. Even in real war, a just prince, while laying hands, in the enemy's country, on all that belongs to the public, respects the lives and goods of individuals: he respects rights on which his own are founded. The object of the war being the destruction of the hostile State, the other side has a right to kill its defenders, while they are bearing arms; but as soon as they lay them down and surrender, they cease to be enemies or instruments of the enemy, and become once more merely men, whose life no one has any right to take. Sometimes it is possible to kill the State without killing a single one of its members; and war gives no right which is not necessary to the gaining of its object. These principles are not those of Grotius: they are not based on the authority of poets, but derived from the nature of reality and based on reason.
The right of conquest has no foundation other than the right of
- ↑ The Romans, who understood and respected the right of war more than any other nation on earth, carried their scruples on this head so far that a citizen was not allowed to serve as a volunteer without engaging himself expressly against the enemy, and against such and such an enemy by name. A legion in which the younger Cato was seeing his first service under Popilius having been reconstructed, the elder Cato wrote to Popilius that, if he wished his son to continue serving under him, he must administer to him a new military oath, because, the first having been annulled, he was no longer able to bear arms against the enemy. The same Cato wrote to his son telling him to take great care not to go into battle before taking this new oath. I know that the siege of Clusium and other isolated events can be quoted against me; but I am citing laws and customs. The Romans are the people that least often transgressed its laws; and no other people has had such good ones.
