Perpetual Peace. Immanuel Kant
slowly by stages scarcely measurable, progressing at one moment, and the next, as it seems, falling behind: he looks beyond the individual, struggling and never attaining, to the race. Here Kant is no pessimist. The capacities implanted in man by nature are not all for evil: they are, he says, “destined to unfold themselves completely in the course of time, and in accordance with the end to which they are adapted.” (Idea of a Universal History from a Cosmopolitan Point of View, 1784. Prop. 1.) This end of humanity is the evolution of man from the stage of mere self-satisfied animalism to a high state of civilisation. Through his own reason man is to attain a perfect culture, intellectual and moral. In this long period of struggle, the potential faculties which nature or Providence has bestowed upon him reach their full development. The process in which this evolution takes place is what we call history.
To man nature has given none of the perfect animal equipments for self-preservation and self-defence which she has bestowed on others of her creatures. But she has given to him reason and freedom of will, and has determined that through these faculties and without the aid of instinct he shall win for himself a complete development of his capacities and natural endowments. It is, says Kant, no happy life that nature has marked out for man. He is filled with desires which he can never satisfy. His life is one of endeavour and not of attainment: not even the consciousness of the well-fought battle is his, for the struggle is more or less an unconscious one, the end unseen. Only in the race, and not in the individual, can the natural capacities of the human species reach full development. Reason, says Kant, (Prop. 2, op. cit.) “does not itself work by instinct, but requires experiments, exercise and instruction in order to advance gradually from one stage of insight to another. Hence each individual man would necessarily have to live an enormous length of time, in order to learn by himself how to make a complete use of all his natural endowments. Or, if nature should have given him but a short lease of life, as is actually the case, reason would then require an almost interminable series of generations, the one handing down its enlightenment to the other, in order that the seeds she has sown in our species may be brought at last to a stage of development which is in perfect accordance with her design.” Man the individual shall travel towards the land of promise and fight for its possession, but not he, nor his children, nor his children’s children shall inherit the land. “Only the latest comers can have the good fortune of inhabiting the dwelling which the long series of their predecessors have toiled—though,” adds Kant, “without any conscious intent—to build up without even the possibility of participating in the happiness which they were preparing.” (Proposition 3.)
The means which nature employs to bring about this development of all the capacities implanted in men is their mutual antagonism in society—what Kant calls the “unsocial sociableness of men, that is to say, their inclination to enter into society, an inclination which yet is bound up at every point with a resistance which threatens continually to break up the society so formed.” (Proposition 4.) Man hates society, and yet there alone he can develop his capacities; he cannot live there peaceably, and yet cannot live without it. It is the resistance which others offer to his inclinations and will—which he, on his part, shows likewise to the desires of others—that awakens all the latent powers of his nature and the determination to conquer his natural propensity to indolence and love of material comfort and to struggle for the first place among his fellow-creatures, to satisfy, in outstripping them, his love of glory and possession and power. “Without those, in themselves by no means lovely, qualities which set man in social opposition to man, so that each finds his selfish claims resisted by the selfishness of all the others, men would have lived on in an Arcadian shepherd life, in perfect harmony, contentment, and mutual love; but all their talents would forever have remained hidden and undeveloped. Thus, kindly as the sheep they tended, they would scarcely have given to their existence a greater value than that of their cattle. And the place among the ends of creation which was left for the development of rational beings would not have been filled. Thanks be to nature for the unsociableness, for the spiteful competition of vanity, for the insatiate desires of gain and power! Without these, all the excellent natural capacities of humanity would have slumbered undeveloped. Man’s will is for harmony; but nature knows better what is good for his species: her will is for dissension. He would like a life of comfort and satisfaction, but nature wills that he should be dragged out of idleness and inactive content and plunged into labour and trouble, in order that he may be made to seek in his own prudence for the means of again delivering himself from them. The natural impulses which prompt this effort—the causes of unsociableness and mutual conflict, out of which so many evils spring—are also in turn the spurs which drive him to the development of his powers. Thus, they really betray the providence of a wise Creator, and not the interference of some evil spirit which has meddled with the world which God has nobly planned, and enviously overturned its order.” (Proposition 4: Caird’s translation in The Critical Philosophy of Kant, Vol. II., pp. 550, 551.)
The problem now arises, How shall men live together, each free to work out his own development, without at the same time interfering with a like liberty on the part of his neighbour? The solution of this problem is the state. Here the liberty of each member is guaranteed and its limits strictly defined. A perfectly just civil constitution, administered according to the principles of right, would be that under which the greatest possible amount of liberty was left to each citizen within these limits. This is the ideal of Kant, and here lies the greatest practical problem which has presented itself to humanity. An ideal of this kind is difficult of realisation. But nature imposes no such duty upon us. “Out of such crooked material as man is made,” says Kant, “nothing can be hammered quite straight.” (Proposition 6.) We must make our constitution as good as we can and, with that, rest content.
The direct cause of this transition from a state of nature and conditions of unlimited freedom to civil society with its coercive and restraining forces is found in the evils of that state of nature as they are painted by Hobbes. A wild lawless freedom becomes impossible for man: he is compelled to seek the protection of a civil society. He lives in uncertainty and insecurity: his liberty is so far worthless that he cannot peacefully enjoy it. For this peace he voluntarily yields up some part of his independence. The establishment of the state is in the interest of his development to a higher civilisation. It is more—the guarantee of his existence and self-preservation. This is the sense, says Professor Paulsen, in which Kant like Hobbes regards the state as “resting on a contract,”[52] that is to say, on the free will of all.[53] Volenti non fit injuria. Only, adds Paulsen, we must remember that this contract is not a historical fact, as it seemed to some writers of the eighteenth century, but an “idea of reason”: we are speaking here not of the history of the establishment of the state, but of the reason of its existence. (Paulsen’s Kant, p. 354.)[54]
In this civil union, self-sought, yet sought reluctantly, man is able to turn his most unlovable qualities to a profitable use. They bind this society together. They are the instrument by which he wins for himself self-culture. It is here with men, says Kant, as it is with the trees in a forest: “just because each one strives to deprive the other of air and sun, they compel each other to seek both above, and thus they grow beautiful and straight. Whereas those that, in freedom and isolation from one another, shoot out their branches at will, grow stunted and crooked and awry.” (Proposition 5, op. cit.) Culture, art, and all that is best in the social order are the fruits of that self-loving unsociableness in man.
The problem of the establishment of a perfect civil constitution cannot be solved, says this treatise (Idea for a Universal History), until the external relations of states are regulated in accordance with principles of right. For, even if the ideal internal constitution were attained, what end would it serve in the evolution of humanity, if commonwealths themselves were to remain like individuals in a state of nature, each existing in uncontrolled freedom, a law unto himself? This condition of things again cannot be permanent. Nature uses the same means as before to bring about a state of law and order. War, present or near at hand, the strain of constant preparation for a possible future campaign or the heavy burden of debt and devastation left by the last—these are the evils which must drive states to leave a lawless, savage state of nature, hostile to man’s inward development, and seek in union the end of nature, peace. All wars are the attempts nature makes to bring about new political relations between nations, relations which, in their very nature, cannot be, and are not desired to
