or combined (on one hand – public, one the other - private). In a narrower sense, war is an armed conflict between states. The right of war is justice, but in a negative meaning: thing that does not contradict to justice. “The first inducements of nature do not contradict it, even on the contrary.” That’s the way in which he tries to prove it. Saving life and limbs, saving belongings, useful for it – correspond to the first inducements of nature. In other words, care of oneself does not contradict to community life, until they break somebody else’s right. The force that doesn’t break another’s right is legal. That means that, according to Gratius:
The sources of wars are the passions of human body (desire to possess valuables)
Just war is possible, which deserves approval of natural and international law.
Gratius defines two stages of just public war:
Solemn just war
Simply just war
“For the war to have solemn character, two conditions are required: it must be waged by the will of highest rulers of the states, and certain customs must be kept… Both of those are required, because any of them is not enough without another.
Public war is not solemn; it can be free from those customs and ceremonies; it can be waged against anyone by anyone’s authority. That means that any person has a right to wage his own war. But as war may cause danger for the whole state most legislatures forbid it. War can be waged only by the highest authority.”
Conclusion
Neither Gratius, nor any other bourgeois scholars of international relations and international law managed to find out the reasons of war and the principle difference between just and unjust war. One of my sources says that only Marxist theory managed it. According to Marxist’ point of view just war is not a predatory one but a war of liberation, which has a goal of protecting the people of external attack or of freeing colonies from the “oppression” of imperialism, etc. And unjust war is a predatory war, which has a goal to conquer and slave the other state’s people. But I must say that these views are out-of-date of course.
