There is no intelligible meaning in the idea of the law of nations as giving a right to make war; for that must be a right to decide what is just, not in accordance with universal, external laws limiting the freedom of each individual, but by means of one-sided maxims applied by force. We must then understand by this that men of such ways of thinking are quite justly served, when they destroy one another, and thus find perpetual peace in the wide grave which covers all the abominations of acts of violence as well as the authors of such deeds. For states, in their relation to one another, there can be, according to reason, no other way of advancing from that lawless condition which unceasing war implies, than by giving up their savage lawless freedom, just as individual men have done, and yielding to the coercion of public laws. Thus they can form a State of nations (_civitas gentium_), one, too, which will be ever increasing and would finally embrace all the peoples of the earth. States, however, in accordance with their understanding of the law of nations, by no means desire this, and therefore reject _in hypothesi_ what is correct _in thesi_. Hence, instead of the positive idea of a world-republic, if all is not to be lost, only the negative substitute for it, a federation averting war, maintaining its ground and ever extending over the world may stop the current of this tendency to war and shrinking from the control of law. But even then there will be a constant danger that this propensity may break out.[131] “Furor impius intus—fremit horridus ore cruento.” (Virgil.)[132] [131] On the conclusion of peace at the end of a war, it might not be unseemly for a nation to appoint a day of humiliation, after the festival of thanksgiving, on which to invoke the mercy of Heaven for the terrible sin which the human race are guilty of, in their continued unwillingness to submit (in their relations with other states) to a law-governed constitution, preferring rather in the pride of their independence to use the barbarous method of war, which after all does not really settle what is wanted, namely, the right of each state in a quarrel. The feasts of thanksgiving during a war for a victorious battle, the hymns which are sung—to use the Jewish expression—“to the Lord of Hosts” are not in less strong contrast to the ethical idea of a father of mankind; for, apart from the indifference these customs show to the way in which nations seek to establish their rights—sad enough as it is—these rejoicings bring in an element of exultation that a great number of lives, or at least the happiness of many, has been destroyed.
