Though in all war there be usually a complication of force and damage, and the aggressor seldom fails to harm the estate, when he uses force against the persons of those he makes war upon; yet it is the use of force only that puts a man into the state of war: for whether by force he begins the injury, or else, having quietly, and by fraud, done the injury, he refuses to make reparation, and by force maintains it, (which is the same thing, as at first to have done it by force) it is the unjust use of force that makes the war: for he that breaks open my house, and violently turns me out of doors; or, having peaceably got in, by force keeps me out; does in effect the same thing; supposing we are in such a state, that we have no common judge on earth, whom I may appeal to, and to whom we are both obliged to submit: for of such I am now speaking. It is the “unjust use of force then, that puts a man into the state of war” with another; and thereby he that is guilty of it makes a forfeiture of his life: for quitting reason, which is the rule given between man and man, and using force, the way of beasts, he becomes liable to be destroyed by him he uses force against, as any savage ravenous beast, that is dangerous to his being.
