Yes, both sides speak of justice and the demands of justice, but these words frequently take on different or opposite meanings according to which side uses them. Hence, when rulers of nations appeal to justice and the demands of justice, they not only disagree on terms, but often increase the tension that exists between their States. And so the belief is engendered that if a nation is to assert its rights and pursue its own interests, there is only one way open to it: to have recourse to violence; ignoring the fact that violence is the source of the very greatest evils.
Mutual trust among rulers of States cannot begin nor increase except by recognition of, and respect for, the moral order.
But the moral order has no existence except in God; cut off from God it must necessarily disintegrate. Moreover, man is not just a material organism. He consists also of spirit; he is endowed with reason and freedom. He demands, therefore, a moral and religious order; and it is this order—and not considerations of a purely extraneous, material order—which has the greatest validity in the solution of problems relating to his life as an individual and as a member of society, and problems concerning individual states and their inter-relations.
