[69] A large part of Kant’s requirements as they are expressed in these Preliminary Articles has already been fulfilled. The first (Art. 1) is recognised in theory at least by modern international law. More cannot be said. A treaty of this kind is of necessity more or less forced by the stronger on the weaker. The formal ratification of peace in 1871 did not prevent France from longing for the day when she might win back Alsace-Lorraine and be revenged on Prussia. Not the treaty nor a consciousness of defeat has kept the peace west of the Rhine, but a reluctant respect for the fortress of Metz and the mighty army of united Germany.
Articles 2 and 6 are already commonplaces of international law. Article 2 refers to practices which have not survived the gradual disappearance of dynastic war. Art. 6 is the basis of our modern law of war. Art. 3 has been fulfilled in the literal sense that the standing armies composed of mercenary troops to which Kant alludes exist no longer. But it is to be feared that Kant would not think that we have made things much better, nor regard our present system of progressive armaments as a step in the direction of perpetual peace. Art. 4 is not likely to be fulfilled in the near future. It is long since Cobden denounced the institution of National Debts—an institution which, as Kant points out, owes its origin to the English, the “commercial people” referred to in the text. Art. 5 no doubt came to Kant through Vattel. “No nation,” says the Swiss publicist, (Law of Nations, II. Ch. iv. § 54) “has the least right to interfere with the government of another,” unless, he adds, (Ch. v. § 70) in a case of anarchy or where the well-being of the human race demands it. This is a recognised principle of modern international law. Intervention is held to be justifiable only where the obligation to respect another’s freedom of action comes into conflict with the duty of self-preservation.
Puffendorf leaves much more room for the exercise of benevolence. The natural affinity and kinship between men is, says he, (Les Devoirs de l’homme et du citoien, II. Ch. xvi. § xi.) “a sufficient reason to authorise us to take up defence of every person whom one sees unjustly oppressed, when he implores our aid and when we can do it conveniently.” (The italics are mine.—[Tr.])
[70] See [p. 137]. The main principle involved in this passage comes from Vattel (op. cit., II. Ch. viii. §§ 104, 105: Ch. ix. §§ 123, 125). A sovereign, he says, cannot object to a stranger entering his state who at the same time respects its laws. No one can be quite deprived of the right of way which has been handed down from the time when the whole earth was common to all men.
[72] Kant believed that, in the newly formed constitution of the United States, his ideal with regard to the external forms of the state as conforming to the spirit of justice was most nearly realised. Professor Paulsen draws attention, in the following passage, to the fact that Kant held the English government of the eighteenth century in very low esteem. (Kant, p. 357, note. See Eng. trans., p. 352, note.) It was not the English state, he says, which furnished Kant with an illustration of his theory:—“Rather in it he sees a form of despotism only slightly veiled, not Parliamentary despotism, as some people have thought, but monarchical despotism. Through bribery of the Commons and the Press, the King had actually absolute power, as was evident, above all, from the fact that he had often waged war without, and in defiance of, the will of the people. Kant has a very unfavourable opinion of the English state in every way. Among the collected notes written by him in the last ten years of the century and published by Reicke (Lose Blätter, I. 129) the following appears:—‘The English nation (gens) regarded as a people (populus) and looked upon side by side with other races is, as a collection of individuals, of all mankind the most highly to be esteemed. But as a state, compared with other states, it is the most destructive, high-handed and tyrannical, and the most provocative of war among them all.’”
Kuno Fischer (op. cit., Vol. V., I. Ch. 11, pp. 150, 151) to whom Professor Paulsen’s reference may here perhaps allude, states that Kant’s objection to the English constitution is that it was an oligarchy, Parliament being not only a legislative body, but through its ministers also executive in the interests of the ruling party or even of private individuals in that party. It seems more likely that what most offended a keen observer of the course of the American War of Independence was the arbitrary and ill-directed power of the king. But see the passage quoted by Fischer (pp. 152, 153) from the Rechtslehre (Part II. Sect. I.) which is, he says, unmistakeably directed against the English constitution and certain temporary conditions in the political history of the country.
