Everything made by man may be destroyed by man; there are no ineffaceable characters except those engraved by nature; and nature makes neither princes nor rich men nor great lords.

War is then not a relationship between one man and another, but a relationship between one State and another, in which individuals are enemies only by accident, not as men, nor even as citizens, but as soldiers; not as members of the fatherland, but as its defenders.
