Kant’s way toward perpetual peace in the 21st century

Hiroo Nakamura (Nagano, Japan)

“May Nagasaki be the last city which has been nuclear-bombed!” – Reasonable people in Japan are ashamed that their country which is famous for being a world technological power had caused the Fukushima nuclear disaster in spite of atomic bomb victims’ hard experiences and innermost wishes in Hiroshima and Nagasaki. This disaster has showed that there had been mistakes in former economic and energy policies. It reflects political weak points not only in Japan but in the whole world. Today, political, cultural and religious conflicts have become more and more complicated. At the beginning of the 21st century, we must now ask over again whether human beings are really on the way to making a steady progress toward the better.

Erasmus of Rotterdam, Immanuel Kant, and Salomo Friedlaender, a forgotten philosopher of the 20th century who called himself “Old-Kantian” and has begun to be rediscovered  today; these philosophers, in their own manner, have warned their contemporaries to end their self-destruction by war, to make every effort toward continual peace, and for that purpose to realize clearly and exactly the morality which, as ratio cognoscendi of freedom, belongs intrinsically to humanity. – Referring to these classical and modern texts and basing on fundamental principles of The Constitution of Japan[1], I defended in my book Für den Frieden[2] that humanity, in spite of negative evidences in history, has without doubt hope for the future  and that the perpetual peace is left entirely up to humanity itself, so that it is education toward becoming a personality that should come into question in the end, because it is the personality that is in reality the subject of freedom as ratio essendi of morality and because this freedom is, for people who wish  for peace from their hearts, exactly the “keystone”[3] of the grand conceptions for perpetual peace, though this concept of freedom is the “stumbling block”[4] for all empiricists. Here, in this lecture, I would like to present you my book above Für den Frieden in outline.

At the beginning of his book Peace Protests (Querela pacis) published in 1517, Erasmus said:

“THUS SPEAKS PEACE: If, in spite of my innocence and regardless of the advantages which I offer them, men hate me, drive me away, and discredit me, nothing remains for me but to deplore the affront they offer me and their iniquity.”[5]

If Erasmus had seen the utterly destroyed Germany and ruined Europe directly after the Second World War, how hard  would he have grieved over the misery again? The German translation of his Querela pacis (Peace Protests)[6] has been quite timely published anew in 1945. The translator, Arthur von Arx, wrote at the end of his epilogue  as follows:

“«Perpetual peace» might  continue to be an ideal. Ideals, however, can’t and should not be judged by visible results. Ideals retain at any rate their lively influence and their moral force, even if only more or less successful realizations testify of their existence.”[7]

Perpetual peace is always an actual task for humanity, which has been formulated by Saint-Pierre and Rousseau as well as by Kant. Maybe it is no exaggeration to say that human beings, since the Enlightenment, especially after the Second World War, have earnestly made efforts to undertake the task and to accomplish it, and that they really made and are making now more remarkable progress in pacifism than before, especially more than in the first half of the 20th century. If Erasmus, who had 500 years before grieved hard over war’s havoc in Europe, had seen the result of the EU today, he would regard its actual situation as a miracle . Politics not only in Europe but in the whole world today is on the whole in a more desirable situation than before. Compared with the  rapidity of technical innovation, the progress of humanity toward perpetual peace is indeed so slow that it looks as if it were stopping or, on the contrary, retrogressing. We can, however, give reasons to the effect that human beings have made or are making steps forward. – First of all, the proposals for perpetual peace made by Saint-Pierre and Rousseau as well as Kant’s philosophical project in the 18th century may be considered as certain examples for that. What  Kant called “unwritten code”[8], today has become, so to speak, a “written code”. For we can make sure of the actual steps toward perpetual peace concretely in various declarations, agreements or constitutions of democratic states in the world: e. g. the United Nations Charter (1945), the Universal Declaration of Human Rights (1948), the International Covenant on Civil and Political Rights (1966), the Maastricht Treaty (1992), the Convention on the Prohibition of Anti-Personnel Mines (1997), the Convention on Cluster Ammunitions (2008). We should regard these facts as a historical sign of progress humanity has made. I would like to give a few more good examples: The Universal Declaration of Human Rights was adopted by a vote of 48 in favor, 0 against, though with 8 abstentions; the Ottawa-Convention which was initially proposed  by the Non-Government Organizations (NGO’s)  gained the signatures of 122 countries  when it opened for signing on 3 December 1997 in Ottawa. 159 States have ratified the Treaty as of December 2011. Currently, 111 states have joined the Convention on Cluster Ammunitions, 77 having ratified it, while  another 34 have signed but not yet ratified it. We can say now like  von Arx in 1945 that ideals retain “their lively influence and their moral force”; rather, human beings are evolving them.

It is difficult to ascertain if  Erasmus had some influence on Rousseau and Kant, for we don’t find in their works any quotations from his Peace Protests. When we, however, read it now over again, we find phrases full of suggestions: what is peace in the world and what is necessary for us to be able to come steadily closer to the goal of perpetual peace? Erasmus’ humanistic thought led into the Enlightenment and evolved into modern pacifism. Erasmus, Rousseau, and Kant: three different characters: Erasmus is distinguished by  faith and rhetorics, while Rousseau is characterized by political thought and Kant by critical philosophy. There is, however, a common point; all of them have realized the freedom of the human being and the moral-teleological substance of reason as well as of internal and external relations among human societies. What Erasmus convinced us of is that there must  be no war and that humanity consists in good will and harmony. Rousseau shed light upon the question of the ideal political system for perpetual peace, whereas it is Kant who  played a decisive part regarding this subject as the first and only philosopher who had laid the philosophical foundation for the question of perpetual peace. He gave, so to speak, Archimedes’ fulcrum to move, i.e. to solve metaphysical problems to philosophers in a position to counsel politicians to realize the truth of politics that “true politics can therefore not take a step without having already paid homage to morals.”[9] Salomo Friedlaender expresses in a decisive ton:

“Since 1781[10],  humanity is urged not only in politics to make a decision on an alternative discovered just by Kant which rests upon freedom:that is, either human reason,  the essence of which is the Law, is ruled by nature (or its creator); or, according to Kant’s revolution of thinking, Reason, which has not only theoretical but also creatively practical force, rules nature.”[11]

The greatest contribution Kant made to  modern philosophy consists in his critical philosophy which opened the way to overcome the difficulties for metaphysics which had troubled humanity so long. Kant says at the beginning of the first edition of his Critique of Pure Reason: “Human reason has this peculiar fate that in one species of its knowledge it is burdened by questions which, as prescribed by the very nature of reason itself, it is not able to ignore, but which, as transcending all its powers, it is also not able to answer.”[12] Kant’s Critique was the first one that, having elucidated the essence of metaphysics, had given the solution for its hard problems. According to Kant, the metaphysicians’ mistakes until then consisted in their understanding of the distinction between analytic (explicative) and synthetic (ampliative) judgements peculiar to human knowledge. Treating the question of peace only analytically, they had to fall into the problem of antinomy between realism and idealism. In fact, metaphysical questions belong essentially to synthetic judgements and it should be necessary for them to “add to the concept of the subject a predicate which has not been in any wise thought in it, and which no analysis could possibly extract from it”[13], i.e. to adopt a priori concept and to use them basing upon “principles other than the principle of contradiction”[14].

According to Kant’s The Metaphysics of Morals, perpetual peace constitutes the entire final end of the doctrine of right belonging essentially to metaphysics.[15] Therefore, in order to avoid blind alleys like scepticism as well as dogmatism or like fruitless idealism as well as warlike realism, in the discussion on the questions of perpetual peace, it is necessary to add a priori concepts to it and to be based on a principle other than the law of contradiction. A priori concepts which should be added to the metaphysical judgement of perpetual peace are “freedom”, “final purpose”, “human dignity” and “human right”, strictly speaking, “the right to live in peace”[16]. Principles other than the law of contradiction are the moral law and moral teleology. The core of four a priori concepts above is freedom, because it is  freedom that is called “innate right”[17] and human dignity and human right as well as final end are possible only under condition that people, i.e. citizens, have realized the morality as ratio cognoscendi of freedom and its moral-teleological nature. Accordingly I designated freedom as ratio essendi of perpetual peace and perpetual peace as ratio cognoscendi of freedom. For human beings’ future should depend on their freedom, i.e. on their free will to make themselves better, to cultivate themselves, and to moralize themselves. It is freedom with which a human being can become human. To deny the reality of freedom means to block the possibility of the future which will open up before the human being and entrust his future to himself. The Future of the human being toward perpetual peace depends entirely on his freedom, whereas it depends on his efforts toward perpetual peace whether he is really a free being. Because of freedom, a human being can regard the task toward perpetual peace as his own vocation and undertake his own future for himself. He has already experienced these facts in historical signs above. Today, we can say now in  Kant’s phrase, “a good ideal of evidence can be put forward to show that in our age, as compared with all previous ages, the human race as a whole has actually made considerable moral progress.”[18] The actual question is: how we step forward? The key to answering this question is education.

At the beginning of his Lectures on Pedagogy, Kant says: “The human being is the only creature that must be educated.”[19] For, “the human being can only become human through education.”[20] – “Practical education is education towards personality, the education of a freely acting being who can support itself and be a member of society, but who can have an inner value for itself.”[21] According to Kant, the “inner value” is what a human being gives with his freedom to himself. That is, because of freedom, he can make efforts to respect the right of life in peace, to make an approach to perpetual peace as his final purpose, and to be worthy of human dignity. Upon a conviction of this moral teleology, Kant based his pedagogy which would answer the fundamental question: how is it possible for humanity to come steadily closer toward perpetual peace which is essentially no empty idea? It resolves into the question of education toward personality. Friedlaender emphasized the importance of Kantian moral philosophy as follows: 

“If people had 150 years ago began to initiate children into the categorical imperative, world wars could thereby probably have been prevented.”[22]

People say that perpetual peace is just an empty or chimerical idea like the “stone of Sisyphus”[23]. Is that right? – In a sense, yes, but on the other hand, no. For human history seems to have been full of vain efforts toward perpetual peace, whereas, from the end of the 20th century downward, we can see clear indications that human beings are making progress toward the better. I would like to say with Kant that human beings’ effort toward perpetual peace never is a Sisyphean labour and that humanity will and can accomplish its own task to approach step by step steadily toward perpetual peace, taking genuine pleasure in realizing that it is really making an effort to be worth of a human being. Maybe it is not an exaggeration to venture to say again in Kant’s phrase very persuasively: – Because “he can do something because he is aware that he ought to do it and cognize freedom within him, which, without the moral law, would have remained unknown to him.”[24] – Because, in view of their situation becoming more serious today, human beings must have realized that the human race is really in a critical situation as: “if a gallows were erected in front of the house where he finds this opportunity and he would be hanged on it immediately after gratifying his lust, he would not then control his inclination.”[25]

In a note in his Critique of Judgment, Kant asked us: “why was our nature given a propensity toward desires of whose futility we are aware?” His answer is very thought-provoking in order that we might realize over again that we are free beings of possibility, so that our future depends completely on ourselves.

“But why our nature was given a propensity toward desires of whose futility we are aware is an anthropological-teleological question. It seems that if we had to assure ourselves that we can in fact produce the object, before we could be determined [by the presentation] to apply our forces, then our forces would remain largely unused. For usually we do not come to know what forces we have in the first place except by trying them out. Hence the deception contained in vain wishes is only the result of a beneficent arrangement in our nature.”[26]

My book Für den Frieden is, so to speak, an actual proposal to open the way for Kant’s philosophical project toward perpetual peace in the 21st century. At the beginning of this book, I wrote: “I would like to dedicate this book to Erasmus as well as human beings” and in its end: “Erasmus’ peace which men hated, drove away, and discredited, and for which remains but to deplore the affront and the iniquity, may he find by this book a place where he can turn! – By this book, too, may people come to their senses and be awakened to their own vocation for themselves as humanity!”

Now, with the mottos of my book, I would like to close this lecture:

“Finally, peace rests largely in the fact of desiring it with all the force of our soul. Indeed, those who desire it grasp every occasion which is favourable to it. They disregard certain justified claims, smooth over difficulties which oppose it, even endure disagreeable things in order to save that great good which is peace.”[27] (Erasmus of Rotterdam)

“The fates lead the willing, drive the unwilling.”[28] (Seneca)

[8] “Since the (narrow or wider) community of the nations of the earth has now gone so far that a violation of right on one place of the earth is felt in all, the idea of a cosmopolitan right is no fantastic and exaggerated way of representing right; it is, instead, a supplement to the unwritten code of the right of a state and the right of nations necessary for the sake of any public rights of human beings and so for perpetual peace; only under this condition can we flatter ourselves that we are constantly approaching perpetual peace.” (ZF, p. 330 [AA08, p. 360])

[16] The fundamental principle of The Constitution of Japan consists in the “right to live in peace”. Its Preamble says: “We recognize that all peoples of the world have the right to live in peace, free from fear and want.” Yoichi Higuchi, a constitutionalist in Japan, says: “Si l’on peut qualifier les libertés classiques de « droits style 18e et 19e siècle » et les droits économiques et sociaux de « droits style 20e siècle », puisqu’ils correspondent respectivement, quant à leur naissance, à l’ère du laissez-faire et à l’époque du dirigisme de l’Etat, on pourrait sans doute dire que notre Constitution fait une reconnaissance anticipée du droit de l’homme « style 21e siècle », en constitutionnalisant ce « droit de vivre dans la paix » ” (Tadakazu Fukase & Yoichi Higuchi, Le constitutionnalisme et ses problèmes au Japon : Une approche comparative, Paris 1984, p. 27).
