APPENDIX I
ON THE DISAGREEMENT BETWEEN MORALS AND POLITICS WITH REFERENCE TO PERPETUAL PEACE
In an objective sense, morals is a practical science, as the sum of laws exacting unconditional obedience, in accordance with which we ought to act. Now, once we have admitted the authority of this idea of duty, it is evidently inconsistent that we should think of saying that we cannot act thus. For, in this case, the idea of duty falls to the ground of itself; “ultra posse nemo obligatur.” Hence there can be no quarrel between politics, as the practical science of right, and morals, which is also a science of right, but theoretical. That is, theory cannot come into conflict with practice. For, in that case, we would need to understand under the term “ethics” or “morals” a universal doctrine of expediency, or, in other words, a theory of precepts which may guide us in choosing the best means for attaining ends calculated for our advantage. This is to deny that a science of morals exists.
Politics says, “Be wise as serpents”; morals adds the limiting condition, “and guileless as doves.” If these precepts cannot stand together in one command, then there is a real quarrel between politics and morals.[147] But if they can be completely brought into accord, then the idea of any antagonism between them is absurd, and the question of how best to make a compromise between the two points of view ceases to be even raised. Although the saying, “Honesty is the best policy,” expresses a theory which, alas, is often contradicted in practice, yet the likewise theoretical maxim, “Honesty is better than any policy,” is exalted high above every possible objection, is indeed the necessary condition of all politics.
The Terminus of morals does not yield to Jupiter, the Terminus of force; for the latter remains beneath the sway of Fate. In other words, reason is not sufficiently enlightened to survey the series of predetermining causes which would make it possible for us to predict with certainty the good or bad results of human action, as they follow from the mechanical laws of nature; although we may hope that things will turn out as we should desire. But what we have to do, in order to remain in the path of duty guided by the rules of wisdom, reason makes everywhere perfectly clear, and does this for the purpose of furthering her ultimate ends.
The practical man, however, for whom morals is mere theory, even while admitting that what ought to be can be, bases his dreary verdict against our well-meant hopes really on this: he pretends that he can foresee from his observation of human nature, that men will never be willing to do what is required in order to bring about the wished-for results leading to perpetual peace. It is true that the will of all individual men to live under a legal constitution according to the principles of liberty—that is to say, the distributive unity of the wills of all—is not sufficient to attain this end. We must have the collective unity of their united will: all as a body must determine these new conditions. The solution of this difficult problem is required in order that civil society should be a whole. To all this diversity of individual wills there must come a uniting cause, in order to produce a common will which no distributive will is able to give. Hence, in the practical realisation of that idea, no other beginning of a law-governed society can be counted upon than one that is brought about by force: upon this force, too, public law afterwards rests. This state of things certainly prepares us to meet considerable deviation in actual experience from the theoretical idea of perpetual peace, since we cannot take into account the moral character and disposition of a law-giver in this connection, or expect that, after he has united a wild multitude into one people, he will leave it to them to bring about a legal constitution by their common will.
It amounts to this. Any ruler who has once got the power in his hands will not let the people dictate laws for him. A state which enjoys an independence of the control of external law will not submit to the judgment of the tribunals of other states, when it has to consider how to obtain its rights against them. And even a continent, when it feels its superiority to another, whether this be in its way or not, will not fail to take advantage of an opportunity offered of strengthening its power by the spoliation or even conquest of this territory. Hence all theoretical schemes, connected with constitutional, international or cosmopolitan law, crumble away into empty impracticable ideals. While, on the other hand, a practical science, based on the empirical principles of human nature, which does not disdain to model its maxims on an observation of actual life, can alone hope to find a sure foundation on which to build up a system of national policy.
Now certainly, if there is neither freedom nor a moral law founded upon it, and every actual or possible event happens in the mere mechanical course of nature, then politics, as the art of making use of this physical necessity in things for the government of men, is the whole of practical wisdom and the idea of right is an empty concept. If, on the other hand, we find that this idea of right is necessarily to be conjoined with politics and even to be raised to the position of a limiting condition of that science, then the possibility of reconciling them must be admitted. I can thus imagine a moral politician, that is to say, one who understands the principles of statesmanship to be such as do not conflict with morals; but I cannot conceive of a political moralist who fashions for himself such a system of ethics as may serve the interest of statesmen.
The moral politician will always act upon the following principle:—“If certain defects which could not have been avoided are found in the political constitution or foreign relations of a state, it is a duty for all, especially for the rulers of the state, to apply their whole energy to correcting them as soon as possible, and to bringing the constitution and political relations on these points into conformity with the Law of Nature, as it is held up as a model before us in the idea of reason; and this they should do even at a sacrifice of their own interest.” Now it is contrary to all politics—which is, in this particular, in agreement with morals—to dissever any of the links binding citizens together in the state or nations in cosmopolitan union, before a better constitution is there to take the place of what has been thus destroyed. And hence it would be absurd indeed to demand that every imperfection in political matters must be violently altered on the spot. But, at the same time, it may be required of a ruler at least that he should earnestly keep the maxim in mind which points to the necessity of such a change; so that he may go on constantly approaching the end to be realised, namely, the best possible constitution according to the laws of right. Even although it is still under despotic rule, in accordance with its constitution as then existing, a state may govern itself on republican lines, until the people gradually become capable of being influenced by the mere idea of the authority of law, just as if it had physical power. And they become accordingly capable of self-legislation, their faculty for which is founded on original right. But if, through the violence of revolution, the product of a bad government, a constitution more in accord with the spirit of law were attained even by unlawful means, it should no longer be held justifiable to bring the people back to the old constitution, although, while the revolution was going on, every one who took part in it by use of force or stratagem, may have been justly punished as a rebel. As regards the external relations of nations, a state cannot be asked to give up its constitution, even although that be a despotism (which is, at the same time, the strongest constitution where foreign enemies are concerned), so long as it runs the risk of being immediately swallowed up by other states. Hence, when such a proposal is made, the state whose constitution is in question must at least be allowed to defer acting upon it until a more convenient time.[148]
It is always possible that moralists who rule despotically, and are at a loss in practical matters, will come into collision with the rules of political wisdom in many ways, by adopting measures without sufficient deliberation which show themselves afterwards to have been overestimated. When they thus offend against nature, experience must gradually lead them into a better track. But, instead of this being the case, politicians who are fond of moralising do all they can to make moral improvement impossible and to perpetuate violations of law, by extenuating political principles which are antagonistic to the idea of right, on the pretext that human nature is not capable of good, in the sense of the ideal which reason prescribes.
