By taking into account some texts published between the first and the second edition of the Critique of Pure Reason that have been neglected by most of those who have dealt with the deduction of the categories, I argue that the core of the deduction is to be identified as the ‘almost single inference from the precisely determined definition of a judgment in general’, which Kant adumbrates in the Metaphysical Foundations in order to ‘make up for the deficiency’ of the (...) A-deduction. Whereas the first step of the B-deduction is an attempt to show that the manifold of an intuition belongs to the ‘necessary unity of self-consciousness’ by means of the synthesis of the understanding, the second step has the task of showing that the very same synthesis is responsible for the spatio-temporal unity of the manifold. Thus, Kant's ‘answer to Hume’ is that no spatio-temporal objects of experience at all are merely ‘given’, independently of the conceptual activities of the understanding. Against the established view I substantiate the claim that with this ‘almost single inference’ of the second proof step the distinction between judgments of perception and judgments of experience consequently vanished from Kant's thinking.

Konstantin Pollok - Kant's Critical Concepts of Motion - Journal of the History of Philosophy 44:4 Journal of the History of Philosophy 44.4 559-575 Muse Search Journals This Journal Contents Kant's Critical Concepts of Motion Konstantin Pollok There are two significant places in Kant's Critical corpus where he discusses the concept of motion. The first is in the Critique of Pure Reason, where in the "Deduction of the Categories" Kant writes: Motion, as an act of the subject , and therefore (...) the synthesis of the manifold in space, first produces the concept of succession—if we abstract from this manifold and attend solely to the act through which we determine the inner sense according to its form. In this passage Kant simply refers to the concept of motion, and the immediate context in which this reference occurs reveals little about what he means by it. In the Metaphysical Foundations of Natural Science, however, motion plays a more significant role, and, concomitantly, it is in his writings on natural science that Kant most fully expresses his thoughts on the subject. For present purposes, the most relevant passage is paragraph 15 of the Preface of the Metaphysical Foundations, where Kant says that the concept of matter had … to be carried through all four of the indicated functions of the concepts of the understanding , where in each a new determination of this concept was added.

IMMANUEL KANT GRADUATED IN 1755 from the University of Königsberg on the basis of the dissertation On Fire and with the essay A New Exposition of the First Principles of Metaphysics written specifically for the occasion; he took up a position as lecturer in the same year. In 1756 he wrote a third Latin essay, the Physical Monadology, and applied for a professorship at the Albertina in Königsberg. The application was unsuccessful and, more significantly, the work failed to attract the (...) attention Kant had hoped. He had to wait until 1770—some fourteen years later—for an appointment as full professor in Königsberg, and it was not until the publication of the Critique of Pure Reason in 1781 that he finally established his reputation as a philosopher.

Against the standard interpretation of Kant's ‘Copernican revolution’ as the prioritization of epistemology over ontology, I argue in this paper that his critique of traditional metaphysics must be seen as a farewell to the perfectionism on which early modern rationalist ontology and epistemology are built. However, Kant does not simply replace ‘perfection’ with another fundamental concept of normativity. More radically, Kant realizes that it is not simply ideas but only the relation of ideas that can be subject to norms, and (...) thus he shifts the focus from the reality of ideas to the validity of judgments. Section 1 of this paper clarifies the pre-Kantian role of the concept of perfection and examines Kant's critical response to that concept. Section 2 identifies Kant's point of departure from the Cartesian ‘way of ideas.’ Section 3 explains the key problem of his novel account of epistemic normativity. I conclude that Kant's anti-perfectionism must be seen as the driving force behind his ‘Copernican revolution’ in order to fully appreciate his mature account of epistemic normativity. (shrink)

Welchen Standards müssen Personen genügen, damit ihre Äußerungen als wahrhaftig angesehen werden? Nicht Wahrhaftigkeit als soziale Tugend und auch nicht Wahrhaftigkeit als notwendige Argumentationsvoraussetzung , sondern die normativen Voraussetzungen wahrhaftiger Äußerungen von Überzeugungen, Werten, Wünschen und Gefühlen einer Person, d. h. eine Analyse der normativen Erfordernisse der Wahrhaftigkeit als Teilaspekt einer Sprachpragmatik, sind das Thema dieses Aufsatzes. Ausgehend von Überlegungen Wittgensteins, John Broomes und Robert Brandoms untersuche ich die normative Feinstruktur der Differenz zwischen dem 'Äußern' und dem 'Besitzen' eines propositionalen (...) Gehalts sowie der Vorsätzlichkeit dieser Differenz im 'Äußern'. Mein Ergebnis ist schließlich: Person B glaubt, daß die Äußerung des propositionalen Gehalts p durch Person A wahrhaftig ist, wenn die Person B der Person A die Festlegung auf p zuweist, die Person B der Person A eine Berechtigung zu p zuweist und die Person B der Person A die Festlegung auf eine Berechtigung zu p zuweist.

The article evaluates the standard edition of Kant's Prolegomena and the Metaphysische Anfangsgründe, trying to show that their standard editions, as found in the fourth volume of the Academy Edition, are seriously flawed. Therefore, volume 4 should be part of the planned revision of the entire edition. Most striking are the defects and inconsistencies in the text of the Prolegomena. Extended philosophical and historical research has shown that this work in its present form cannot have been published with Kant's approval. (...) The text and the editorial apparatus of the Metaphysical Foundations also leave much to be desired. Until such a revision of the Academy Edition one is better advised to rely on the editions of these texts published by the Felix Meiner Verlag. (shrink)

Konstantin Pollok offers the first book-length analysis of Kant's theory of normativity that covers foundational issues in theoretical and practical philosophy as well as aesthetics. Interpreting Kant's 'critical turn' as a normative turn, he argues that Kant's theory of normativity is both original and radical: it departs from the perfectionist ideal of early modern rationalism, and arrives at an unprecedented framework of synthetic a priori principles that determine the validity of our judgments. Pollok examines the hylomorphism in Kant's theory of (...) normativity and relates Kant's idea of our reason's self-legislation to the 'natural right' tradition, revealing Kant's debt to his predecessors as well as his relevance to contemporary debates on normativity. This book will appeal to academic researchers and advanced students of Kant, early modern philosophy and intellectual history. (shrink)

For philosophers of German idealism and early German Romanticism, the imagination is central to issues ranging from hermeneutics to transcendental logic and from ethics to aesthetics. This volume of new essays brings together, for the first time, comprehensive and critical reflections on the significances of the imagination during this period, with essays on Kant and the imagination, the imagination in post-Kantian German idealism, and the imagination in early German romanticism. The essays explore the many and varied uses of the imagination (...) and discuss whether they form a coherent or shared notion or whether they embody points of philosophical divergence within these traditions. They shed new light on one of the most important and enigmatic aspects of human nature, as understood in the context of a profoundly influential era of western thought. (shrink)

I draw attention to a 12-page Vorarbeit to Kant’s Prolegomena from the so-called Scheffner-Nachlaß and argue that the parallel Kant draws there between the possibility of theoretical and practical synthetic a priori propositions provides important insight into the development of his account of practical autonomy in the Groundwork. Based on a brief sketch of the role synthetic a priori propositions play in the development of Kant’s critical philosophy, I conclude that for Kant the objective validity of any science depends on (...) the objective validity of a number of synthetic a priori propositions.

Name der Zeitschrift: Kant-Studien Jahrgang: 105 Heft: 4 Seiten: 509-530.

I. Kant hat mit seiner universalistischen, formalistischen und kognitivistischen Konzeption moralisch-praktischer Gründe in Gegenüberstellung zu seiner instrumentalistischen Konzeption nicht-moralisch-praktischer Gründe eine Begrifflichkeit geschaffen, die es erlaubt, handlungsleitende Überzeugungen hinsichtlich ihres Geltungsanspruchs und ihrer Verbindlichkeit zu differenzieren. Von einem ‚Sollen‘ spricht Kant in beiden Fällen. Nicht nur der kategorische Imperativ, der unbedingt gebietet, „ich soll niemals anders verfahren als so, daß ich auch wollen könne, meine Maxime solle ein allgemeines Gesetz werden“ , sondern auch hypothetische Imperative, die bedingt gebieten, „ich soll (...) etwas thun, darum weil ich etwas anderes will“, nehmen bei Kant die normative Form eines ‚Sollens‘ an. In beiden Fällen ergehen also Forderungen an die Vernunft, doch es ist alles andere als klar, in welcher Beziehung diese Sollensformen zueinander stehen. Bestünde gar keine solche Beziehung, so träte praktische Vernunft im Plural auf – wohlgemerkt in einer einzigen Person, welcher sich der Sinn beider Imperativformen erschlossen hat. Da eine solche Form von Schizophrenie der Willensbestimmung nicht der Kantischen Vorstellung von praktischer Vernunft entspricht, stellt sich die Frage nach der Einheit von bedingtem und unbedingtem Sollen.
