The Guarantee Of Perpetual Peace

1. Even if a people were not compelled through internal discord to be restrained by public laws, war would bring this about, working from outside.

For, according to the contrivance of nature which we have mentioned, every people finds another tribe in its neighbourhood, pressing upon it in such a manner that it is compelled to form itself internally into a state to be able to defend itself as a power should.

Now the republican constitution is the only one which is perfectly adapted to the rights of man, but it is also the most difficult to establish and still more to maintain. So generally is this recognised that people[p. 153] often say the members of a republican state would require to be angels,[142] because men, with their self-seeking propensities, are not fit for a constitution of so sublime a form.

But now nature comes to the aid of the universal, reason-derived will which, much as we honour it, is in practice powerless. And this she does, by means of these very self-seeking propensities, so that it only depends—and so much lies within the power of man—on a good organisation of the state for their forces to be so pitted against one another, that the one may check the destructive activity of the other or neutralise its effect. And hence, from the standpoint of reason, the result will be the same as if both forces did not exist, and each individual is compelled to be, if not a morally good man, yet at least a good citizen. The problem of the formation of the state, hard as it may sound, is not insoluble, even for a[p. 154] race of devils, granted that they have intelligence.

It may be put thus:—“Given a multitude of rational beings who, in a body, require general laws for their own preservation, but each of whom, as an individual, is secretly inclined to exempt himself from this restraint: how are we to order their affairs and how establish for them a constitution such that, although their private dispositions may be really antagonistic, they may yet so act as a check upon one another, that, in their public relations, the effect is the same as if they had no such evil sentiments.” Such a problem must be capable of solution. For it deals, not with the moral reformation of mankind, but only with the mechanism of nature; and the problem is to learn how this mechanism of nature can be applied to men, in order so to regulate the antagonism of conflicting interests in a people that they may even compel one another to submit to compulsory laws and thus necessarily bring about the state of peace in which laws have force. We can see, in states actually existing, although very imperfectly organised, that, in externals, they already approximate very nearly to what the Idea of right prescribes, although the principle of morality is certainly not the cause. A good political constitution, however, is not to be expected as a result of progress in morality; but rather, conversely, the good moral condition of a nation is to be looked for, as one of[p. 155] the first fruits of such a constitution. Hence the mechanism of nature, working through the self-seeking propensities of man (which of course counteract one another in their external effects), may be used by reason as a means of making way for the realisation of her own purpose, the empire of right, and, as far as is in the power of the state, to promote and secure in this way internal as well as external peace. We may say, then, that it is the irresistible will of nature that right shall at last get the supremacy. What one here fails to do will be accomplished in the long run, although perhaps with much inconvenience to us. As Bouterwek says, “If you bend the reed too much it breaks: he who would do too much does nothing.”

2. The idea of international law presupposes the separate existence of a number of neighbouring and independent states; and, although such a condition of things is in itself already a state of war, (if a federative union of these nations does not prevent the outbreak of hostilities) yet, according to the Idea of reason, this is better than that all the states should be merged into one under a power which has gained the ascendency over its neighbours and gradually become a universal monarchy.[143] For the wider the sphere of their jurisdiction, the more laws lose in force; and soulless despotism, when it has choked the seeds of good, at last sinks into anarchy.

Nevertheless it is the desire of every state, or of its ruler, to attain to a permanent condition of peace in this very way; that is to say, by subjecting the whole world as far as possible to its sway. But nature wills it otherwise. She employs two means to separate nations, and prevent them from intermixing: namely, the differences of language and of religion.[144] These differences bring with them a tendency to mutual hatred, and furnish pretexts for waging war. But, none the less, with the growth of culture and the gradual advance of men to greater unanimity of principle, they lead to concord in a state of peace which, unlike the despotism we have spoken of, (the churchyard of freedom) does not arise from the weakening of all forces, but is brought into being and secured through the equilibrium of these forces in their most active rivalry.

3. As nature wisely separates nations which the will of each state, sanctioned even by the principles of international law, would gladly unite under its own sway by stratagem or force; in the same way, on the other hand, she unites nations whom the principle of a cosmopolitan right would not have secured against violence and war. And this union she brings about through an appeal to their mutual interests.

The commercial spirit cannot co-exist with war, and sooner or later it takes possession of every nation. For, of all the forces which lie at the command of a state, the power of money is probably the most reliable. Hence states find themselves compelled—not, it is true, exactly from motives of morality—to further the noble end of peace and to avert war, by means of mediation, wherever it threatens to break out, just as if they had made a permanent league for this purpose. For great alliances with a view to war can, from the nature of things, only very rarely occur, and still more seldom succeed.

In this way nature guarantees the coming of perpetual peace, through the natural course of human propensities: not indeed with sufficient certainty to enable us to prophesy the future of this ideal theoretically, but yet clearly enough for practical purposes. And thus this guarantee of nature makes it a duty that we should labour for this end, an end which is no mere chimera.
