In 1792 and 1798 Kant noticed two basic problems with hisMetaphysical Foundations of Natural Science (MAdN) which opened a crucial gap in the Critical system as a whole. Why is theMAdN so important? I show that the Analogies of Experience form an integrated proof of transeunt causality. This is central to Kant's answer to Hume. This proof requires explicating the empirical concept of matter as the moveable in space, it requires the specifically metaphysical principle that every physical event has an (...) external cause, and it requires a metaphysical principle regarding the individuation of spatio-temporal things. These three doctrines are not defended in the firstCritique, but only in theMAdN. Kant's transcendental analysis of the conditions of experience thus requires the special metaphysics of theMAdN. This marks an important shift in Kant's view of the metaphysical basis of the transcendental philosophy. (shrink)

Kant’s dissertation for the Master’s degree Succinct Exposition of Some Meditations on Fire was written in Latin in 1755 as a sample (specimen) preceding a Master’s exam, but its first printing did not appear until 1838. What is the relevance of this Master’s dissertation for historical and philosophical studies? To answer this question I analyse the structure and give a brief summary of the dissertation, look at the history of its writing and try to identify the place of this work (...) among Kant’s other papers on natural philosophy. I then demonstrate that Kant’s concept of ether as an elastic matter of fire, heat and light containing the forces of attraction and repulsion originates in the dissertation On Fire. I identify the provisions in Kant’s early works which he later develops in the Master’s dissertation and establish continuity between the text of On Fire and the so-called Physical Monadology, draw parallels between the ideas enunciated by Kant in his first dissertation and the interpretation of ether in the printed works that followed. Finally, I put forward the hypothesis of the heuristic potential of the On Fire treatise for the analysis of Kant’s manuscript legacy. Perhaps this dissertation will enable researchers to clear up some tangled propositions in Kant’s Opus Postumum. However, a series of further studies is needed to verify the hypothesis. (shrink)

This essay explores the undervalued methodological elements underpinning Kant’s Transition from Metaphysical Foundations of Natural Science to Physics in Opus postumum. I do this by drawing...

In this essay, I call attention to Kant’s and Whewell’s attempt to provide bridging principles between a priori principles and scientific laws. Part of Kant’s aim in the Opus postumum (ca. 1796-1803) was precisely to bridge the gap between the metaphysical foundations of natural science (on the Metaphysical Foundations of Natural Science (1786) see section 1) and physics by establishing intermediary concepts or ‘Mittelbegriffe’ (henceforth this problem is referred to as ‘the bridging-problem’). I argue that the late-Kant attempted to show (...) that the concept of ‘moving force’, an intermediary concept derived from a priori principles, could be given empirical content so that concrete scientific knowledge is arrived at. Thus, the late-Kant wished not only to show that proper scientific laws are necessary a priori (as he had shown in the Metaphysical Foundations of Natural Science) but also that intermediary concepts could be derived from a priori principles which, when interpreted empirically, resulted in the specific forces as established by physics (see section 2). Of course, William Whewell never knew about Kant’s Opus postumum and his attempt to bridge the gap between the metaphysical foundations of science and physics. However, it is striking that Whewell had similar concerns about the Critique of Pure Reason and the Metaphysical Foundations of Natural Science as Kant himself. According to Whewell, the Kantian project was incomplete because it did not show how ‘modifications’ (in the sense of concretizations) of a priori principles could result in empirical laws (section 3). Next, it will be argued, by taking into account several of Whewell’s philosophical notebooks which have scarcely been studied systematically, that Whewell’s doctrine of Fundamental Ideas grew out of his dissatisfaction with the Kantian project with respect to the bridging problem and that his own philosophical position should be seen as an attempt to bypass the bridging-problem.

This essay investigates the transformation of the faculty of understanding in Kant’s Transition from Metaphysical Foundations of Natural Science to Physics drafts found in Opus postumum. I argue that in fascicles X and XI Kant implicitly reverses the architectonic order of sensibility and understanding. Without an account of this reversal, Kant’s critique of Isaac Newton’s conception of phenomena and the so called Selbstsetzungslehre in fascicle VII fall apart. I argue that what is at stake is a challenge Kant makes to (...) his own presuppositions and a challenge to the Kantian philosopher who wishes to stay with a strictly ‘critical’ Kant. (shrink)

Over two hundred years after Immanuel Kant’s death, the first full, critical, and digital edition of his last manuscript is currently being completed by the Berlin-Brandenburgische Akademie der Wissenschaften. This edition stands in institutional continuity with Wilhelm Dilthey’s monumental Akademieausgabe of Kant’s writings that was grounded in Dilthey’s lastingly influential concept of the national, literary-philosophical archive. The new edition showcases Kant’s dynamic writing process as a matter of investigation in its own right. As I argue here, it brings into view (...) the constitutive role of the archive for both texts and interpretative practices. A historical perspective that links the legacy of the Akademieausgabe with the digital edition of the Opus postumum highlights the changing role of the archive in emphasising or de-emphasising the manuscript’s resistance to certain appropriations and stylisations of Kant as a thinker.

The founders of the Marburger Schule of Neo-Kantianism, Hermann Cohen and Paul Natorp, laid an emphasis upon a Platonic understanding of mathematics and logic as the paradigmatic epistemological basis of philosophy. Their successors, namely Ernst Cassirer and Nicolai Hartmann, made obvious, however, that new biological thinking can have a strong influence on ontology as well as on the theory of knowledge. They could show that biology was no longer to be treated as a metaphysical system in that pejorative meaning of (...) metaphysics which Kant had so severely been opposing. Against the anti-realistic approach of the older neo-Kantians who wanted to eliminate Kant's thing-in-itself (Ding an sich), both Cassirer and Hartmann returned to a form of realism by way of Hegel's philosophical results and reflections on his method. This makes clear that their realism is still to be taken as a more of less monistic idealism. However, considering that modern biology as an antimetaphysical force became influential in their system for the first time and that it did so in two different but - on second thoughts - complementary ways, it becomes clear that it was necessary to change the paradigms of any neo-Kantian philosophy. Cassirer proved this by his development as a philosopher with a strong historical impetus while Hartmann as a more systematical philosopher only pointed in that direction. (shrink)

The importance of German Naturphilosophie for the development of a unified view of nature is often emphasized. The search for ultimate unity of natural phenomena, however, was already too common among physicists of the waning 18th century to ascribe its popularity to the influence of philosophers. To avoid the plethora of imponderable fluids, many „atomists”︁ reduced electric, magnetic, thermal, and chemical phenomena to a dualism of contrary principles, thereby prefiguring the „dynamic”︁ ideas of romantic Naturphilosophen.In particular we show how Schelling's (...) early account of his Naturphilosophie was shaped by J. A. Deluc's atomistic theory of gases and vapours. (shrink)

1795 erschien die 1. Auflage von Kants Schrift Zum ewigen Frieden. Zu einer der vordringlichsten, von der Philosophie aber häufig vernachlässigten Aufgaben der Politik stellt sie bis heute den wichtigsten klassischen Text dar. Kant entfaltet in ihm die philosophischen Grundlagen für eine internationale Rechts- und Friedensgemeinschaft. Gleichzeitig stellt er sich aber auch die Frage nach einer Vermittlung von normativer Theorie und politischer Praxis. In 12 Beiträgen wird Kants Text in diesem Band 'entschlüsselt', interpretiert, auf seine systematische Überzeugungskraft und auf seine (...) politische Tragweite hin untersucht und in seinen und unseren sozialgeschichtlichen Kontext gestellt. Der kooperative Kommentar wurde anlässlich des 300. Jubiläums Immanuel Kants überarbeitet und auf den neuesten Forschungsstand gebracht. Mit Beiträgen von Reinhard Brandt, Monique Castillo, Michael W. Doyle, Volker Gerhardt, Otfried Höffe, Wolfgang Kersting, Pierre Laberge, Jean-Christophe Merle, Hans Saner. (shrink)
