BOOK REVIEWS 273 my judgment, in the fact that he has limited the historical inquiry to the scholarly study of documents and discussions without showing those cultural, social, psychological, and economic motivations which formed an accompaniment to the individual protagonists of the discussions. The motivation for what a philosopher says is not justified by revealing only his most immediate opponent's name and ideas, but by showing, as Goldmann (La communautd humaine chez Kant, Paris, 1948) and, very briefly, Stark (The Sociology of Knowledge) did, the reason for his thinking and his presuppositional needs. In the case of Kant, it is obvious that we cannot leave out his pietist formation, the fears about the French Revolution and Hume's scepticism. The historicity of a study cannot be limited to the history of polemics or to the discovery of documents which, theoretically, add nothing to what an author has already stated in his works. The vast philological material Pupi has gathered, seems to me very good, and it represents, I think, the greatest value of Pupi's work, because of its usefulness in the field of the sociology of knowledge. And to this field I take the liberty of referring Pupi for an example of a method that is historical and not tautological. ANTONELLA GUARALDI Kant und der Friede. By Wilhelm Miiller. (Diisseldorf: Monitor-Verlag, 1962. Pp. 16.) Perpetual Peace records the noble and humane dream of an old man. Such dreams are not without historical precedent, but rarely have they been invested with the earnestness and the conceptual rigor of a Kant--even of a Kant in his declining years. This short essay is at the very least a minor but noteworthy contribution to political theory. Its main thesis call be simply stated. A truly lasting peace can be achieved only through the agency of a world federation of states operating under moral law. The moral law in question is an extension of the guiding principles of Kant's ethics from the private to the public sphere. It is contrary to the dictates of reason as well as of moral conscience to suppose that political order may be conceived or established apart from or even in opposition to moral law. A state or nation, Kant declares, is a free moral person, possessed of an inviolable integrity, not to be exploited as a thing for purposes of aggrandizement on the part of other states. Were that all that Perpetual Peace contained, the essay would stand as testimony to Kant's political idealism. But he pursues with equal seriousness the question of how such an ideal might be realized in practice. Underlying Kant's federalism is his republicanism, his insistence that the only sound civil constitution is one in which each citizen is free, equal, and fully represented under common law publicly promulgated. It is Kant's contention -perhaps less naive today than it might have seemed earlier in this century--that where the consent of the subjects is required, as it is under a republican form of government , to decide whether or not there shall be war, they may be expected to think twice before bringing such sufferings upon themselves. Further, Kant sees in the ever-tightening and expanding web of international relations a natural deterrent to war, since any war will increasingly involve most if not all of mankind. Both considerations appeal, not to the questionable good will of politicians, but to enlightened self-interest. Finally, Kant lays down a series of "preliminary articles" whose purpose is to specify the conditions without which perpetual peace, as things stand, will not even become a real possibility. Among the principles here formulated are that a peace treaty is invalid if made with secret reservations, that the autonomy and constitutional integrity of independent states must be preserved, that standing armies must gradually be abolished, that national debts shall not be contracted externally, and that in the event of war "dishonorable stratagems" such as assassination, 274 HISTORY OF PHILOSOPHY poisoning, spying, etc., which would render postwar mutual confidence impossible, shall not be countenanced. It is mainly with an eye to these preliminary articles that Professor Wilhelm Miiller argues for Kant's relevance to contemporary...
