Perpetual Peace: A Philosophical Essay

Immanuel Kant

prevent the injustice done from being very great. 3.—=Cosmopolitan Law.= We may pass over this department of right in silence, for, owing to its analogy with international law, its maxims are easily specified and estimated. * * * * * In this principle of the incompatibility of the maxims of international law with their publicity, we have a good indication of the non-agreement between politics and morals, regarded as a science of right. Now we require to know under what conditions these maxims do agree with the law of nations. For we cannot conclude that the converse holds, and that all maxims which can bear publicity are therefore just. For anyone who has a decided supremacy has no need to make any secret about his maxims. The condition of a law of nations being possible at all is that, in the first place, there should be a law-governed state of things. If this is not so, there can be no public right, and all right which we can think of outside the law-governed state,—that is to say, in the state of nature,—is mere private right. Now we have seen above that something of the nature of a federation between nations, for the sole purpose of doing away with war, is the only rightful condition of things reconcilable with their individual freedom. Hence the agreement of politics and morals is only possible in a federative union, a union which is necessarily given _a priori_, according to the principles of right. And the lawful basis of all politics can only be the establishment of this union in its widest possible extent. Apart from this end, all political sophistry is folly and veiled injustice. Now this sham politics has a casuistry, not to be excelled in the best Jesuit school. It has its mental reservation (_reservatio mentalis_): as in the drawing up of a public treaty in such terms as we can, if we will, interpret when occasion serves to our advantage; for example, the distinction between the _status quo_ in fact (_de fait_) and in right (_de droit_). Secondly, it has its probabilism; when it pretends to discover evil intentions in another, or makes, the probability of their possible future ascendency a lawful reason for bringing about the destruction of other peaceful states. Finally, it has its philosophical sin (_peccatum philosophicum_, _peccatillum_, _baggatelle_) which is that of holding it a trifle easily pardoned that a smaller state should be swallowed up, if this be to the gain of a nation much more powerful; for such an increase in power is supposed to tend to the greater prosperity of the whole world.[154] [154] We can find the voucher for maxims such as these in Herr Hofrichter Garve’s essay, _On the Connection of Morals with Politics_, 1788. This worthy scholar confesses at the very beginning that he is unable to give a satisfactory answer to this question. But his sanction of such maxims, even when coupled with the admission that he cannot altogether clear away the arguments raised against them, seems to be a greater concession in favour of those who shew considerable inclination to abuse them, than it might perhaps be wise to admit. Duplicity gives politics the advantage of using one branch or the other of morals, just as suits its own ends. The love of our fellowmen is a duty: so too is respect for their rights. But the former is only conditional: the latter, on the other hand, an unconditional, absolutely imperative duty; and anyone who would give himself up to the sweet consciousness of well-doing must be first perfectly assured that he has not transgressed its commands. Politics has no difficulty in agreeing with morals in the first sense of the term, as ethics, to secure that men should give to superiors their rights. But when it comes to morals, in its second aspect, as the science of right before which politics must bow the knee, the politician finds it prudent to have nothing to do with compacts and rather to deny all reality to morals in this sense, and reduce all duty to mere benevolence. Philosophy could easily frustrate the artifices of a politics like this, which shuns the light of criticism, by publishing its maxims, if only statesmen would have the courage to grant philosophers the right to ventilate their opinions. With this end in view, I propose another principle of public right, which is at once transcendental and affirmative. Its formula would be as follows:—“All maxims which require publicity, in order that they may not fail to attain their end, are in agreement both with right and politics.” For, if these maxims can only attain the end at which they aim by being published, they must be in harmony with the universal end of mankind, which is happiness; and to be in sympathy with this (to make the people contented with their lot) is the real business of politics. Now, if this end should be attainable only by publicity, or in other words, through the removal of all distrust of the maxims of politics, these must be in harmony with the right of the people; for a union of the ends of all is only possible in a harmony with this right. I must postpone the further development and discussion of this principle till another opportunity. That it is a transcendental formula is quite evident from the fact that all the empirical conditions of a doctrine of happiness, or the _matter_ of law, are absent, and that it has regard only to the _form_ of universal conformity to law. * * * * * If it is our duty to realise a state of public right, if at the same time there are good grounds for hope that this ideal may be realised, although only by an approximation advancing _ad infinitum_, then perpetual peace, following hitherto falsely so-called conclusions of peace, which have been in reality mere cessations of hostilities, is no mere empty idea. But rather we have here a problem which gradually works out its own solution and, as the periods in which a given advance takes place towards the realisation of the ideal of perpetual peace will, we hope, become with the passing of time shorter and shorter, we must approach ever nearer to this goal.
