Vorrangig als der "strengste Methodenfanatiker und Logizist" der Marburger Schule des Neukantianismus bekannt, trat Natorp jedoch genau an diesem Punkt mit der selbständigen Form seines späten Philosophierens hervor: der Überschreitung der Methode in der Idee einer allgemeinen Logik. Unter allgemeiner Logik versteht er die streng einheitliche logische Grundlegung der Gegenstandssetzung, ja aller irgendwie logisch erfaßlichen Setzung. Damit war ein Zugang geschaffen zu der von Natorp angestrebten Erkenntnis des Geistigen in seiner Ureinheit, aus der erst die Besonderungen hervorgehen.

In der Reihe werden herausragende monographische Untersuchungen und Sammelbände zu allen Aspekten der Philosophie Kants veröffentlicht, ebenso zum systematischen Verhältnis seiner Philosophie zu anderen philosophischen Ansätzen in Geschichte und Gegenwart. Veröffentlicht werden Studien, die einen innovativen Charakter haben und ausdrückliche Desiderate der Forschung erfüllen. Die Publikationen repräsentieren damit den aktuellsten Stand der Forschung.

A new understanding of Kant’s theory of a priori knowledge and his natural philosophy emerges from Jeffrey Edwards’s mature and penetrating study. In the Third Analogy of Experience, Kant argues for the existence of a dynamical plenum in space. This argument against empty space demonstrates that the dynamical plenum furnishes an a priori necessary condition for our experience and knowledge of an objective world. Such an a priori existence proof, however, transgresses the limits Kant otherwise places on transcendental arguments in (...) the _Critique of Pure Reason_ because it establishes a _material_ transcendental condition of possible experience. This finding motivates Edwards to examine the broader context of Kant’s views about matter, substance, causal influence, and physical aether in connection with the developmental history of his theory of transcendental idealism. Against the backdrop of early modern metaphysics and contemporaneous physical theory, Edwards explicates the origins of the Third Analogy in Kant’s early work on the metaphysics of nature. The argument against empty space presented in the Third Analogy reveals a central aspect of Kant’s transcendental theory of experience that Edwards explains lucidly. By clarifying the epistemological standpoint at issue in the Third Analogy, he shows that the fundamental revisions to which Kant subjects his theory of knowledge in the _Opus postumum_ not only originate in his precritical metaphysics of nature but are developments of an argument central to the _Critique of Pure Reason_ itself. Edwards’s work is important to scholars working in the history of philosophy and the history and philosophy of science, as well as to Kant specialists. (shrink)

This essay partly builds on and partly criticizes a striking idea of Dieter Henrich. Henrich argues that Kant's distinction in the first Critique between the question of fact (quid facti) and the question of law (quid juris) provides clues to the argumentative structure of a philosophical "Deduction". Henrich suggests that the unity of apperception plays a role analogous to a legal factum. By contrast, I argue, first, that the question of fact in the first Critique is settled by the Metaphysical (...) Deduction, which establishes the purity of origin of the Categories, and, second, that in the second Critique, the relevant factum is the Fact of Reason, which amounts to the fact that the Moral Law is pure in origin. (shrink)

Taking account of Kant's unpublished mss., the author presents a close textual interpretation of Kant's logic of concepts.

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. (shrink)

In the Critique of Pure Reason, Kant refers often and with no apparent hesitation or sense of ambiguity to the mind. He does so not only in his justly famous destruction of rationalist proofs of immaterialism, but throughout his own, positive, ‘transcendental’ account in the Transcendental Aesthetic and Transcendental Analytic. In the first edition of the Critique, he even proposed what he adventurously called a ‘transcendental psychology’ and, although this strange discipline seemed to disappear in the second edition, he left (...) in that edition all his frequent references to forms ‘lying in the mind,’ and to the mind, or the self, or the subject of experience, or the ego, doing this or that. Curiously, though, despite an extensive secondary literature, there is in that literature relatively little discussion of what these expressions, in a proper, strictly Kantian sense, are supposed to refer to. There are two imaginative, extremely suggestive articles by Sellars, some hints at connections with eighteenth century psychology offered by Weldon, a tenebrous book by Heidemann, and some recent attention to the general issue of ‘Kant's theory of mind’ by Ameriks and Kitcher. (shrink)

I argue that §§15–20 of the B-Deduction contain two independent arguments for the applicability of a priori concepts, the first an argument from above, the second an argument from below. The core of the first argument is §16's explanation of our consciousness of subject-identity across self-attributions, while the focus of the second is §18's account of universality and necessity in our experience. I conclude that the B-Deduction comprises powerful strategies for establishing its intended conclusion, and that some assistance from empirical (...) psychology might well have produced a completely successful argument. (shrink)

Despite Kemp Smith's claims to the contrary, I show that there is good reason to believe that Kant was aware of Hume's attack on personal identity. My interpretive claim is that we can make sense of many of Kant's puzzling remarks in the subjective deduction by assuming that he was trying to reply to Hume's challenge. My substantive claim is that Kant succeeds in defending a notion of the self as a continuing sequence of informationally interdependent states.

The interpretation of transcendental arguments remains a contentious issue for contemporary epistemology. It is usually agreed that they originated in Kant's theoretical philosophy and were intended to have some kind of anti-sceptical efficacy. I argue that the sceptic with whom Kant was concerned has been consistently misidentified. The actual sceptic was Hume, questioning whether the faculty of reason can justify any of our judgements whatsoever. His challenge is a sceptical argument regarding rule-following which engenders a vicious regress. Once this sceptical (...) threat is properly identified, the prospects of transcendental arguments must be re-evaluated. (shrink)

The series, founded in 1970, publishes works which either combine studies in the history of philosophy with a systematic approach or bring together systematic studies with reconstructions from the history of philosophy. Monographs are published in English as well as in German. The founding editors are Erhard Scheibe (editor until 1991), Günther Patzig (until 1999) and Wolfgang Wieland (until 2003). From 1990 to 2007, the series had been co-edited by Jürgen Mittelstraß.

This paper is about the nature of the relationship between (1) the doctrine of Non-Conceptualism about mental content, (2) Kant's Transcendental Idealism, and (3) the Transcendental Deduction of the Pure Concepts of the Understanding, or Categories, in the B (1787) edition of the Critique of Pure Reason, i.e., the B Deduction. Correspondingly, the main thesis of the paper is this: (1) and (2) yield serious problems for (3), yet, in exploring these two serious problems for the B Deduction, we also (...) discover some deeply important and perhaps surprising philosophical facts about Kant's theory of cognition and his metaphysics. (shrink)

In this paper, I claim that Kant’s subjective deduction in the first edition of the KrV is to be understood in terms of an investigation of the fundamental force(s) (Grundkraft) of the soul, an investigation essential to Wolffian psychology and much debated throughout Germany in the second half of the 1700’s. I argue that the subjective deduction is indeed presented by means of the exposition of the three-fold syntheses but only insofar as these syntheses are employed as pointers towards each (...) of three original sources of cognition. Only taken as such can we do justice not only to the argument’s unique concern as distinct from that of the objective deduction, but also to its dependence upon the justificatory results of that deduction which was after all Kant’s “primary concern”. (shrink)

In the transcendental deduction, the central argument of the Critique of Pure Reason, Kant seeks to secure the objective validity of our basic categories of thought. He distinguishes objective and subjective sides of this argument. The latter side, the subjective deduction, is normally understood as an investigation of our cognitive faculties. It is identified with Kant’s account of a threefold synthesis involved in our cognition of objects of experience, and it is said to precede and ground Kant’s proof of the (...) validity of the categories in the objective deduction. I challenge this standard reading of the subjective deduction, arguing, first, that there is little textual evidence for it, and, second, that it encourages a problematic conception of how the deduction works. In its place, I present a new reading of the subjective deduction. Rather than being a broad investigation of our cognitive faculties, it should be seen as addressing a specific worry that arises in the course of the objective deduction. The latter establishes the need for a necessary connection between our capacities for thinking and being given objects, but Kant acknowledges that his readers might struggle to comprehend how these seemingly independent capacities are coordinated. Even worse, they might well believe that in asserting this necessary connection, Kant’s position amounts to an implausible subjective idealism. The subjective deduction ismeant to allay these concerns by showing that they rest on a misunderstanding of the relation between these faculties. This new reading of the subjective deduction offers a better fit with Kant’s text. It also has broader implications, for it reveals the more philosophically plausible account of our relation to the world as thinkers that Kant is defending – an account that is largely obscured by the standard reading of the subjective deduction.

Der Autor bietet eine Darstellung spannungsreicher Formen der transzendentalen Einheit, die Kants Auffassung der Synthesis erhellt. Die Abhandlung beginnt mit Reflexionen zur Synthesis, die den historischen und systematischen Rahmen der Untersuchung bestimmen, und erläutert dann Unterscheidungen und Übergänge zwischen Kritik, Transzendentalphilosophie und Metaphysik als Teilen des Systems der reinen Philosophie. Damit wird die verkannte Funktion dieser Systematik in der Aufstellung des apriorischen Leitfadens für den Erkenntnisgebrauch der Vernunft umrissen. Ein Leitfadenproblem, mit dem sich die,,metaphysische Deduktion" der Kategorien beschäftigt, liegt aber (...) zuallererst im Kern der Kritik. Das zweite Kapitel legt diesen verschlüsselten Textabschnitt aus, insbesondere seinen grundlegenden, oft von der Frage nach der Vollständigkeit der Kategorientafel überschatteten Anspruch, die Begriffe a priori der Einheit aller Verstandesfunktionen ‑ der Synthesis der Anschauung und des Urteils ‑ systematisch darzustellen. Die Überlegung zur Verstandesfunktion gibt schließlich Anlass, die bislang nicht hinterfragte Annahme, die Ausdrücke,,reiner Verstandesbegriff" und,,Kategorie" seien bloß Synonyme, in Frage zu stellen.

This landmark book is now reissued in a new edition that has been vastly rewritten and updated to respond to recent Kantian literature.

This is the first full-length biography in more than fifty years of Immanuel Kant, one of the giants amongst the pantheon of Western philosophers as well as the one with the most powerful and broad influence on contemporary philosophy. It is well known that Kant spent his entire life in an isolated part of Prussia living the life of a typical university professor. This has given rise to the view that Kant was a pure thinker with no life of his (...) own, or at least none worth considering seriously. In this biography, Manfred Kuehn debunks that myth once and for all. Taking account of the most recent scholarship Professor Kuehn allows the reader to follow the same journey that Kant himself took in emerging as a central figure in modern philosophy. (shrink)

Kants Reflexion uber die -Notwendigkeit- ist von entscheidender Wichtigkeit innerhalb der radikalen Transformation der Metaphysik des XVIII. Jahrhunderts. Es ist andererseits sehr schwer, seine vorkritischen Werke uberhaupt zu verstehen und die Idee einer neuen Systematik der Philosophie als Kritik der reinen Vernunft nachzuvollziehen, wenn man die Auseinandersetzung Kants mit den Begriffen der Moglichkeit, Wirklichkeit und Notwendigkeit nicht in ihren Details begreift. Was heisst uberhaupt -Notwendigkeit- und -Notwendig-Sein- bei Kant?".

Two currents of thought dominated Western philosophy in the seventeenth and eighteenth centuries: Continental Rationalism and British Empiricism. Despite the gradual dissemination of British ideas on the Continent in the first decades of the eighteenth century, these fundamentally disparate philosophical outlooks seemed to be wholly irreconcilable. However, the publication of Immanuel Kant's Critique of Pure Reason in 1781 presented an entirely new method of philosophical reasoning that promised to combine the virtues of Rationalism with the scientific rigour of Empiricism. This (...) book offers the first extended analysis of Kant's method of proof in philosophy. The author constructs a model based on Kant's own statements about his procedure and then examines his famous proofs in light of it. Great emphasis is placed on historical accuracy and the debunking of popular myths about Kant's aims and doctrines. The result is a compelling new picture of Kant that will challenge current assumptions. (shrink)

The role and place of transcendental psychology in Kant's Critique of Pure Reason has been a source of some contention. This work presents a detailed argument for restoring transcendental psychology to a central place in the interpretation of Kant's Analytic, in the process providing a detailed response to more "austere" analytic readings.

This key collection of essays sheds new light on long-debated controversies surrounding Kant’s doctrine of idealism and is the first book in the English language that is exclusively dedicated to the subject. Well-known Kantians Karl Ameriks and Manfred Baum present their considered views on this most topical aspect of Kant's thought. Several essays by acclaimed Kant scholars broach a vastly neglected problem in discussions of Kant's idealism, namely the relation between his conception of logic and idealism: The standard view that (...) Kant's logic and idealism are wholly separable comes under scrutiny in these essays. A further set of articles addresses multiple facets of the notorious notion of the thing in itself, which continues to hold the attention of Kant scholars. The volume also contains an extensive discussion of the often overlooked chapter in the Critique of Pure Reason on the Transcendental Ideal. Together, the essays provide a whole new outlook on Kantian idealism. No one with a serious interest in Kant's idealism can afford to ignore this important book. (shrink)

This book is the first detailed study of Kant's method of 'transcendental reflection' and its use in the Critique of Pure Reason to identify our basic human cognitive capacities, and to justify Kant's transcendental proofs of the necessary a priori conditions for the possibility of self-conscious human experience. Kenneth Westphal, in a closely argued internal critique of Kant's analysis, shows that if we take Kant's project seriously in its own terms, the result is not transcendental idealism but realism regarding physical (...) objects. Westphal attends to neglected topics - Kant's analyses of the transcendental affinity of the sensory manifold, the 'lifelessness of matter', fallibilism, the semantics of cognitive reference, four externalist aspects of Kant's views, and the importance of Kant's Metaphysical Foundations for the Critique of Pure Reason - that illuminate Kant's enterprise in new and valuable ways. His book will appeal to all who are interested in Kant's theoretical philosophy. (shrink)

This is a book about Kant's views on causality as understood in their proper historical context. Specifically, Eric Watkins argues that a grasp of Leibnizian and anti-Leibnizian thought in eighteenth-century Germany helps one to see how the critical Kant argued for causal principles that have both metaphysical and epistemological elements. On this reading Kant's model of causality does not consist of events, but rather of substances endowed with causal powers that are exercised according to their natures and circumstances. This innovative (...) conception of Kant's view of causality casts a light on Kant's philosophical beliefs in general, such as his account of temporality, his explanation of the reconciliation of freedom and determinism, and his response to the skeptical arguments of Hume.

This book highlights Kant's fundamental contrast between the mechanistic and dynamical conceptions of matter, which is central to his views about the foundations of physics, and is best understood in terms of the contrast between objects of sensibility and things in themselves.

This book, first published in 2000, offers translations of the initial critical reactions to Kant's philosophy. Also included is a selection of writings by Kant's contemporaries who took on the task of defending the critical philosophy against early attacks. The first aim of this collection is to show in detail how Kant was understood and misunderstood by his contemporaries. The second aim is to reveal the sorts of arguments that Kant and his first disciples mounted in their defense of the (...) theoretical philosophy. The third aim of the book is to contribute to an understanding of the development of Kant's critical philosophy after its initial formulation in the Critique of Pure Reason, and in particular why Kant made the changes he did in the second edition of the work in 1787. This collection, which includes a glossary of key terms and biographical sketches of the critics on both sides of the debate, is a major addition to Kant scholarship and should be seen as a companion volume to the Cambridge Edition of the Works of Immanuel Kant.

This is the first book in English to elucidate the central issues in the work of Johann Gottlieb Fichte, a figure crucial to the movement of philosophy from Kant to German idealism. The book explains Fichte's notion of subjectivity and how his particular view developed out of Kant's accounts of theoretical and practical reason. Fichte argued that the subject has a self-positing structure which distinguishes it from a thing or an object. Thus, the subject must be understood as an activity (...) rather than a thing and is self-constituting in a way that an object is not. In the final chapter, Professor Neuhouser considers how this doctrine of the self-positing subject enables us to understand the possibility of the self's autonomy, or self-determination. (shrink)

In Kant and the Demands of Self-Consciousness, Pierre Keller examines Kant's theory of self-consciousness and argues that it succeeds in explaining how both subjective and objective experience are possible. Previous interpretations of Kant's theory have held that he treats all self-consciousness as knowledge of objective states of affairs, and also that self-consciousness can be interpreted as knowledge of personal identity. By developing this striking new interpretation Keller is able to argue that transcendental self-consciousness underwrites a general theory of objectivity and (...) subjectivity at the same time.

The prevailing interpretation of Kant’s _First Critique _in Anglo-American philosophy views his theory of a priori knowledge as basically a theory about the possibility of empirical knowledge, or the a priori conditions for that possibility. Instead, Robert Greenberg argues that Kant is more fundamentally concerned with the possibility of a priori knowledge—the very possibility of the possibility of empirical knowledge in the first place. Greenberg advances four central theses: the _Critique_ is primarily concerned about the possibility, or relation to objects, (...) of a priori_,_ not empirical knowledge, and Kant’s theory of that possibility is defensible; Kant’s transcendental ontology must be distinct from the conditions of the possibility of a priori knowledge; the functions of judgment, in Kant’s discussion of the Table of Judgments, should be seen according to his transcendental logic as having content, not as being just logical forms of judgment making; Kant’s distinction between and connection of ordering relations and reference relations have to be kept in mind to avoid misunderstanding the _Critique_. At every step of the way Greenberg contrasts his view with the major interpretations of Kant by commentators like Henry Allison, Jonathan Bennett, Paul Guyer, and Peter Strawson. Not only does this new approach to Kant present a strong challenge to these dominant interpretations, but by being more true to Kant’s own intent it holds promise for making better sense out of what have been seen as the _First Critique_’s discordant themes.

This book is a study of the second-edition version of the 'Transcendental Deduction', which is one of the most important and obscure sections of Kant's Critique of Pure Reason. By way of a close analysis of the B-Deduction, Adam Dickerson makes the distinctive claim that the Deduction is crucially concerned with the problem of making intelligible the unity possessed by complex representations - a problem that is the representationalist parallel of the semantic problem of the unity of the proposition. Along (...) the way he discusses most of the key themes in Kant's theory of knowledge, including the nature of thought and representation, the notion of objectivity, and the way in which the mind structures our experience of the world.
