Kant’s Metaphysical Deduction of the Categories justifies their apriority, i.e. that their contents originate in the understanding itself, while the Transcendental Deduction justifies their objectivity, both in that they purport to represent objects of experience and that they do so successfully. The apriority of the categories, as explained in terms of acts of synthesis required for having sensible intuitions of objects, is justified by establishing their generic identity with logical functions of judgment, i.e. acts of judgment required for referring (...) concepts to objects. The objective purport of the categories is justified by establishing that sensible intuitions fall under them. To finally justify that the categories represent successfully, i.e. that the objects of our intuitions fall under them, it is established that the representations of space and time do, namely by showing that the features addressed in their Metaphysical Expositions, too, are to be explained in terms of acts of synthesis.

I argue that Kant's Critique of Pure Reason offers a positive metaphysical account of the thinking self. Previous interpreters have overlooked this account, I believe, because they have held that any metaphysical view of the self would be incompatible with both Kant's insistence on the limitations of cognition and with his project in the Paralogisms. Closer examination, however, shows that neither of those aspects of the Critique precludes a metaphysical account of the self, and that (...) other aspects (namely, the structure of Kant's overall project and the commitments of his claims in the Transcendental Deduction) require such an account. Drawing on a principle of 'effect-relative composition,' I argue that Kant's self is neither an activity, a form, nor a representation, but instead an individual constituted by the thing or things that bring about the unity of a course of experience.

In his recent book,The Evolution of Modern Metaphysics, Adrian W. Moore takes Kant to play a crucial role in the evolution of modern philosophy; yet, for him, Kant’s metaphysics is ultimately and profoundly unsatisfactory. In this article, I examine several of Moore’s objections and provide replies. My claim is that Moore’s reading points to fundamental issues, yet these are not issues of Kant’s transcendental idealism, but of the traditional idealism his view has often been taken to represent.

: In the first edition of his book on the completeness of Kant’s table of judgments, Klaus Reich shortly indicates that the B-version of the metaphysical exposition of space in the Critique of pure reason is structured following the inverse order of the table of categories. In this paper, I develop Reich’s claim and provide further evidence for it. My argumentation is as follows: Through analysis of our actually given representation of space as some kind of object, the (...) class='Hi'>metaphysical exposition will show that this representation is secondary to space considered as an original, undetermined and as such unrepresentable intuitive manifold. Now, following Kant, the representation of any kind of object involves diversity, synthesis and unity. In the case of our representation of space as formal intuition, this involves, firstly, a manifold a priori, i.e. space as pure form, delivered by the transcendental Aesthetic, secondly, a figurative, productive synthesis of that manifold, and, thirdly, the unity provided by the categories. Analysing our given representation of space – the task of the metaphysical exposition – amounts to dismantling its unity and determine its characteristics with respect to the categories. (shrink)

Kant's reasoning in his special metaphysics of nature is often opaque, and the character of his a priori foundation for Newtonian science is the subject of some controversy. Recent literature on the Metaphysical Foundations of Natural Science has fallen well short of consensus on the aims and reasoning in the work. Various of the doctrines and even the character of the reasoning in the Metaphysical Foundations have been taken to present insuperable obstacles to accepting Kant's claim (...) to ground Newtonian science. Gordon Brittan and Gerd Buchdahl, amongst others, have argued that Kant's stated aims in this case are not to be taken at face value, and that prior ontological commitments play a hidden but central role in Kant's special metaphysics. ;Michael Friedman has shown how Kant's stated aims can be taken seriously with his ingenious reconstruction of the Metaphysical Foundations as a demonstration of the a priori basis for our thinking bodies to be in true motion and in absolute space. However, Friedman does not address the issue of matter theory--despite the importance of the issue to Kant. I argue that a strict reading of both the stated aims and doctrines of the Metaphysical Foundations is possible, since much of Kant's reasoning about the empirical concept of matter can be explained by his views on how the construction of empirical concepts is possible. ;Kant's quasi-mathematical constructions are pivotal in Friedman's interpretation. Constructibility is Kant's criterion of acceptability for the concepts of natural science. Yet Kant notoriously fails to construct the dynamical concept of matter, and accepts this failure with an equally notorious complacency. I argue that Kant's criteria of empirical concept construction, apart from any prior ontological commitments, are enough to generate his views on matter. Kant's failure to construct the requisite concept of matter can be ascribed to a missing law of nature, a law of the relation of forces the discovery of which Kant thought imminent. I conclude that matter theory is central to the Metaphysical Foundations, but that this does not undermine Kant's stated aim of giving the a priori ground of Newtonian science. (shrink)

Discusses central aspects of Kant's work on the nature of morality and the basis of moral obligation. In examining the categorical imperative and the hypothetical imperative, emphasizes the real nature of the distinction between these principles: whereas the former is binding upon every one, the latter is binding only upon some individuals, namely those individuals who want the end for which a prescribed action is a means. Also considers the nature of the will, Kant's criterion of the rightness (...) of a right action, and two criticisms of Kant's view of morality that arise from his attempt to offer a general answer to the question ‘Why ought an action be performed?’ Then turns to Kant's proof of freedom, which it is claimed just barely misses making the right point that action is only possible under the idea of freedom. Concludes by examining Kant's proof of immortality and the existence of God. (shrink)

Kant's political thinking is predominantly evaluated in contractarian terms, though recent contributions have also emphasized the natural law influence on him. This paper argues that the assimilation of Kant into either tradition is problematic. An analysis of his account of political obligation cannot ignore the distinctiveness of Kant's general philosophical framework. Two recurrent Kantian themes are crucial to a reconstruction of his political argument. The first is the tension between freedom and causality, or nature. The second is the (...) role of reflective judgment in practical reasoning. The paper analyses Kant's property argument, and his related account of political obligation, from the perspective of these Kantian themes. Kant's ‘antinomy of Right’, formulated in the context of his property argument, is interpreted as a conflict between freedom and nature, and in analogy with the third antinomy of the Critique of Pure Reason. Kant's obscure theorem, the lex permissiva, is central to his ‘solution’ to the antinomy. The theorem is best understood as a reflective practical judgment, through which agents are brought to acknowledge that their obligations of justice towards one another are a direct entailment of their respective claims to property. The connection between property rights and political obligations is thus intrinsic, not extrinsic; the acknowledgement of that connection an act of reflective judgment, not contractual. (shrink)

One of Kant’s central central claims in the Critique of Pure Reason is that we cannot have knowledge of things as they are in themselves. This claim has been regarded as problematic in a number of ways: whether Kant is entitled to assert both that there are things in themselves and that we cannot have knowledge of them, and, more generally, what Kant’s commitment to things in themselves amounts to. A number of commentators deny that Kant is committed to (...) there actually being an aspect of reality which we cannot cognise; they argue that he is committed merely to the idea that we cannot avoid the concept of things as they are in themselves. I will argue in this paper that while transcendental idealism is partly an epistemological position, it is also partly a metaphysical position, and in specific, that Kant is committed to the claim that the things we cognise have, in addition to the way they appear to us, a nature that is independent of us, which we cannot cognise.

Kant famously insists that free will is a condition of morality. The difficulty of providing a demonstration of freedom has left him vulnerable to devastating criticism: critics charge that Kant's post-Groundwork justification of morality amounts to a dogmatic assertion of morality's authority. My paper rebuts this objection, showing that Kant offers a cogent demonstration of freedom. My central claim is that the demonstration must be understood in practical rather than theoretical terms. A practical demonstration of x works by bringing (...) x into existence, and what the demonstration of freedom brings into existence is a moral will, a will regulated by the moral law and capable of acting in accordance with it. Since to act morally is to act freely, bringing a moral will into existence actualizes our capacity for freedom and demonstrates that we possess it. To confirm the viability of such a demonstration, Kant must establish that agents can regulate their wills by practical principles, and that practical judgments are efficacious of themselves (i.e., that non-Humean motivational internalism is true). Kant, I argue, is successful on both counts. (shrink)

Kant’s criticism of Metaphysics is informed by his reception of Hume’s skepticism. While the claims of the synthetic a priori, for Kant, constitute a transcendental refutation of Hume’s skepticism, Kant remains in fundamental sympathy with Hume’s empiricism. On the one hand he invokes the synthetic a priori in limiting the unbridled empiricism that conflates the distinction between sources of knowledge and origin of knowledge. On the other hand he also underscores the inherent limitation of human knowledge as legislated by (...) the same empirical ideal, so that in the final analysis there is a fundamental tension in the critical philosophy with respect to Kant’s commitment to idealism and empiricism.

My aim is to demonstrate the specificities and differences between transcendental deduction of concepts and deduction of the fundamental principles of pure practical reason in Kant’s metaphysics. First of all it is necessary to examine Kant’s attitude to the metaphysics of his time and the problem of its new justification. Kant in his philosophy explicated not only the theoretical world of cognition, but also the practical world of freedom. Accordingly, the fundamental means of proving metaphysics’ claims are the deduction (...) of pure concepts of understanding and the deduction of the principles of pure practical reason. The underlying premises of the Kantian project of reviving metaphysics, “the Copernican Turn”, the critical methods and basic principles of transcendental idealism also provide the methodological basis of transcendental deduction, a new method of proving the claims of metaphysics in various spheres of human being. Proceeding from the above, I analyse the essence, structure and the peculiarities as well as the differences between the deduction of experience and the deduction of freedom. I single out the following features of the two types of deduction. First, theoretical use of reason is aimed at objects while practical reason is aimed at noumena, the foundations of will and freedom. Second, the transcendental deduction of space and time, as well as the deduction of categories, is preceded by transcendental reduction, which is absent in the deduction of freedom. Third, Kant orients the methodological movement of deductions in opposite directions. Theoretical deduction proceeds from pure forms of sensible intuition to concepts of understanding and thence to fundamental principles. Practical deduction proceeds from a priori principles to the concepts of the metaphysics of morals and thence to moral feelings. Fourth, deduction in the theoretical sphere forbids speculative reason to go beyond experience. Practical deduction has pointed to the intelligible world and has proved its “legitimacy”. (shrink)

In this chapter, I argue that Kant can be read as holding that "ought" judgments follow from certain "is" judgments by mere analysis. More specifically, I defend an interpretation according to which (1) Kant holds that “S ought to F” is analytically equivalent to “If, as it can and would were there no other influences on the will, S’s faculty of reason determined S’s willing, S would F” and (2) Kant’s notions of reason, the will, and freedom are all fundamentally (...) non-normative. Not only does this reading have significant textual support, but, I claim, it also sheds light on why Kant takes freedom and morality to mutually imply one another. Moreover, while Kant does take there to be a gap between moral judgments and empirical descriptive statements, that gap is consistent with the analysis in question. I conclude by arguing that this rejection of the is-ought gap is not as philosophically implausible as it might seem, with a focus on G.E. Moore and Hume’s arguments for certain ‘gaps’ between the normative and the non-normative. (shrink)

This essay attempts to render intelligible (you will pardon the pun) Kant's peculiar claims about the intelligible at A 539/B 567 – A 541/B 569 in the first Critique, in which he asserts that (1) ... [t]his acting subject would now, in conformity with his intelligible character, stand under no temporal conditions, because time is only a condition of appearances, but not of things in themselves. In him no action would begin or cease. Consequently it would not be (...) subjected to the law of all determination of everything alterable in time: everything which happens finds its causes in the appearances (of the previous state). In a word, his causality, in so far as it is intellectual, would not stand in the series of empirical conditions which the event in the world of sense makes necessary. (A 539/B 567 - A 540/B 568) ... in so far as it is noumenon, nothing happens in him, no alteration which requires dynamical determination in time .... One would quite rightly say of him, that it of itself begins his effects in the world of sense, without the action's beginning in him himself ... (A 541/B 569)2 What does Kant mean by claiming that intellectual causality is such that in one's intelligible character as noumenal agent, actions neither begin nor end, nor does anything happen in one? Do these claims have meaning merely by contrast to the familiar experience of empirical causality, in which actions have discrete durations and events occur? Is he merely inferring from this familiar sensible experience an ontologically and metaphysically independent, epistemically inaccessible "world," which can be conceptualized only through the negation of those terms and propositions that characterize this one? Or is he offering a.. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Concepts, Judgments, and Unity in Kant's Metaphysical Deduction of the Relational Categories CHARLES NUSSBAUM 1. INTRODUCTION TO ANY ATTENTIVEREADERof the section of the Critique of Pure Reason' known as the "Metaphysical Deduction of the Categories" (A67/B92-A83/B to9), one paragraph in that section stands out particularly by virtue of its special importance for Kant's developing argument: The same function Which gives unity to the various representations (...) in ajudgment also gives unity to the mere synthesis of various representations in an intuition; and this unity, in its most general expression, we entitle the pure concept of the understanding. The same understanding, through the same operations by which in concepts, by means of analytical unity, it produced the logical form of a judgment, also introduces a transcendental content into its representations, by means of the synthetic unity of the manifold of intuition in general.... (CPR A79/B loS) The importance of this paragraph is, however, more than equaled by its difficulties, which center on the question of how the function which operates by means of analytical unity can be the same as one that operates by means of the synthetic unity of the manifold of intuition in general. Put shortly, the problem is this. If the functions are really the same, then how do we distinguish at all between analytic and synthetic operations? But if they are different, then how can these forms of judgment serve as a clue for the discovery of the categories? ' Immanuel Kant, Critiqueof Pure Reason, trans. Norman KempSmith (London: Macmillan and Co., Ltd., 1963).Hereafter CPR. [89] 9~ JOURNAL OF THE HISTORY OF PHILOSOPHY 28:1 JANUARY 1990 The results of this dilemma which can be observed in the literature are not surprising: commentators tend to grasp one horn or the other. They either emphasize the difference between analysis and synthesis, and reject or dilute the claims as to sameness of function; or they take seriously Kant's argument concerning sameness of functions, and try to minimize the difference between analysis and synthesis. The major twentieth-century representant of the former approach is Kemp Smith," and of the latter, Paton. 3 This latter approach has found a formidable contemporary champion in the person of Henry Allison. By Allison's own admission,4 however, his position on this controversial topic was suggested (in part) by arguments first put forward over fifty years ago by Klaus Reich in a most remarkable book entitled Die Volls~ndigkeit der Kantischen Urteilstafel, 5 a book, by the way, also greatly admired by Paton. 6 In the first section of this paper I will try to show that Reich's arguments are rather more subtle than Allison apparently takes them to be, and that Reich is one commentator who attempts to go between the horns of the dilemma described above, and who essays an interpretation of our crucial paragraph that unifies its seemingly divergent tendencies. In the second section of the paper I will introduce some interpretive elements of my own. 2. Let us begin by reacquainting ourselves with Kant's notion of analytical unity, one aspect of this debate which is not particularly controversial and is largely agreed upon by all parties. For Kant, analytical unity is the sort of unity achieved by all general concepts (conceptus communes) insofar as they abstract from all differences that subsist between the objects under them, or the lower concepts subordinated to them. 7 A general concept unifies these objects or concepts by means of a common mark or set of marks. Thus Kant's example at CPR A69/B94 of the unification of bodies under the concepts 'body' and 'divisible' is a perfectly representative instance of unification via analytical unity, as the function upon which such concepts "rest."

In Chapter 8 of Kant’s Critique of Pure Reason and the Method of Metaphysics, one of Gabriele Gava’s aims is to argue that Kant’s critique of Wolff’s dogmatic method has two levels: one directed against Wolff’s metaphilosophical views and one attacking his actual procedures of argument. After providing a brief summary of the main claims Gava makes in Chapter 8 of his book, in this paper I argue two things. First, I argue against Gava’s claim that the two forms (...) of dogmatism he distinguishes between are incompatible. Second, I suggest, contrary to Gava, that Kant’s critique of these two forms of dogmatism both operate on the metaphilosophical level in the sense that they both target the dogmatist’s beliefs or theory about the method they take themselves to be following.

According to Kant’s Metaphysical Foundations of Natural Science, a proper science is organized according to rational principles and has a pure a priori rational part, its metaphysical foundation. In the second edition Preface to the first Critique, Kant claims that his account of time explains the a priori possibility of Newton’s laws of motion. I argue that Kant’s proof of the law of inertia fails, and that this casts doubt on Kant’s enterprise of providing a priori foundations (...) for Newton’s physics. (shrink)

This article argues that Fichte is correct in claiming, as he does in the Foundations of Natural Right, that a derivation of the law of right from the moral law is impossible because the former relies on lex permissiva. I focus on Kant’s deduction of the concept of merely intelligible possession in the Metaphysics of Morals precisely because Kant attempts what Fichte says is not possible. By illustrating the problems involved in the concept of the lex permissiva, one is then (...) in a position to see why Fichte believes the derivations mustremain separate and why Fichte stresses that the law of right must be argued for without reference to morality or the moral law.

Kant’s Critique of Pure Reason (KrV) presents a priori knowledge of synthetic truths as posing a philosophical problem of great import whose only possible solution vindicates the system of transcendental idealism. The work does not accord any such significance to a priori knowledge of analytic truths. The intelligibility of the contrast rests on the well-foundedness of Kant’s analytic–synthetic distinction and on his claim to objectively or correctly classify key judgments with respect to it. Though the correctness of Kant’s classification is (...) vital to his philosophical project, it has been vigorously challenged since he introduced his famous distinction of judgments. The aim of this essay is to explore several metaphysical motives contributing to Kant’s objective classification claim that have been underemphasized and in part overlooked in the large literature on the topic.

To vindicate morality against skeptical doubts, Kant must show that agents can be moved to act independently of their sensible desires. Kant must therefore answer a motivational question: how does an agent get from the cognition that she ought to act morally to acting morally? Affectivist interpretations of Kant hold that agents are moved to act by feelings, while intellectualists appeal to cognition alone. To overcome the significant shortcomings of each view, I develop a hybrid theory of motivation. My central (...) interpretive claim is that Kant is a special kind of motivational internalist: on his view, agents are moved to act by a feeling of intellectual pleasure at the prospect of accomplishing a task they have set for themselves, a feeling that originates in free choice. The resulting theory is immune to the challenges facing intellectualism and affectivism, thus strengthening the prospects of Kant’s justification of morality. (shrink)

In the opening essay Melnick develops a compelling case for the idea that Kant held to a constructivist theory of space and time. By this he means that space and time exist only in the “flowing construction” by which pure intuition, and later the productive synthesis of the transcendental imagination, generate seamless continuities between one sensation and another. The exposition moves from the Transcendental Aesthetic to the Transcendental Deduction, where Melnick claims that the cognition of space and time is (...) a matter of bringing this flowing construction under rules specified by the categories of the understanding. In his approach to the Analogies of Experience, Melnick overcomes the apparently relational and objectivist description of space and time to show that the exposition of the categories of relation is not only consistent with the constructivist theory of space and time, but presupposes it.

This paper uncovers a much-neglected ambiguity in Kant’s conception of rational religion, namely, a confusion regarding the public communicability of moral faith, which would in turn render faith and knowledge indistinguishable. The few scholars who have noticed this ambiguity pursue its epistemic dimensions, but this paper explores its ramifications for Kant’s claim that coherent moral agency requires religious faith, taking issue with Lawrence Pasternack’s recent interpretation. Once one notices Kant has two methods for distinguishing conviction from persuasion, one is better (...) able to understand the connection he draws between religious conviction and conscientious character, and the corresponding connection between mere persuasion and spurious faith. While Kant does not explicitly acknowledge this parallel, this paper reveals that it is in play across the Kantian corpus, and is especially perspicuous in his analysis of the biblical figures of Job and his comforters.

A series of attempts have been made to determine Kant’s exact position towards theodicy, and to understand whether it is a direct consequence of his critical philosophy or, rather, whether it is merely linked to some inner development within his critical philosophy. However, I argue that the question of Kant’s critical relation to theodicy has been misunderstood; and that in fact, Kant redefines the essence of the theodicean question anew. After introducing some major aspects of Kant‘s new conception of theodicy, (...) I show how understanding this conception is necessary for correctly analysing his specific arguments against theodicy. I demonstrate this point by examining Kant’s second argument against theodicy, in which he tackles the Leibnizian problem of ‘metaphysical evil’, and show why, in light of the above, interpretations thus far have failed to capture the essence of Kant’s claim in this regard.

In this paper, I examine Kant's famous objection to the ontological argument: existence is not a determination. Previous commentators have not adequately explained what this claim means, how it undermines the ontological argument, or how Kant argues for it. I argue that the claim that existence is not a determination means that it is not possible for there to be non-existent objects; necessarily, there are only existent objects. I argue further that Kant's target is not merely ontological arguments (...) as such but the larger ‘ontotheist’ metaphysics they presuppose: the view that God necessarily exists in virtue of his essence being contained in, or logically entailed by, his essence. I show that the ontotheist explanation of divine necessity requires the assumption that existence is a determination, and I show that Descartes and Leibniz are implicitly committed to this in their published versions of the ontological argument. I consider the philosophical motivations for the claim that existence is a determination and then I examine Kant's arguments in the Critique of Pure Reason against it. (shrink)

It is only two years since Immanuel Kant published his monumental Critique of Pure Reason.As part of entering into the spirit of this ‘untimely review’, I shall pretend that only the first edition of the Critique exists. This has a bearing on some claims that I shall make about differences between the content of the Prolegomena and that of the Critique. Despite its formidable difficulty, that book has already generated intense interest in the philosophical community. Those who are still (...) struggling to come to terms with its dense and subtle argumentation, or who may not even have started to read it yet but who know from the furore that it has created that it needs to be high on their ‘to read’ list, might easily despair at the prospect of having now to contend with another volume on the same broad range of subjects by the same author. This prospect is not, however, as daunting as it seems. In fact, it should afford some solace, at least if we are to believe claims that Kant makes on beh. (shrink)

If there is to be any progress in the debate about what sort of positive moral status Kant can give the emotions, we need a taxonomy of the terms Kant uses for these concepts. It used to be thought that Kant had little room for emotions in his ethics. In the past three decades, Marcia Baron, Paul Guyer, Barbara Herman, Nancy Sherman, Allen Wood and others have argued otherwise. Contrary to what a cursory reading of the Groundwork may indicate, Kant (...) thinks the emotions play an important role in the moral life. I want to extend the work of Baron, Guyer, Herman, Sherman and Wood in three ways. First, I will set out in a diagram Kant's taxonomy of feelings and emotions. Agreement on such a taxonomy should make it easier to evaluate debates about Kant and the emotions. Second, I will focus on a certain subclass of emotions – reason-caused affects – that have previously received little attention, even from these Kant scholars. Third, these scholars base much of their defence of Kant on his later works – especially the Metaphysics of Morals and the Anthropology – but Kant's fairly rich taxonomy of the emotions, including reason-caused affects, is clearly in place at least as early as the Critique of Judgment . I believe that the Critique of Judgment is an importantly ignored resource for understanding the moral role of the emotions for Kant. The third Critique makes positive, philosophically interesting claims about the emotions and morality. Kant emphasizes certain roles for emotions in this work that he develops to the same extent nowhere else. Nevertheless, the Critique of Judgment goes all but unmentioned by many who write on these issues. In what follows, I will defend as many of my claims as possible using the third Critique. (shrink)

This paper examines the young Kant’s claim that all motion is relative, and argues that it is the core of a metaphysical dynamics of impact inspired by Leibniz and Wolff. I start with some background to Kant’s early dynamics, and show that he rejects Newton’s absolute space as a foundation for it. Then I reconstruct the exact meaning of Kant’s relativity, and the model of impact he wants it to support. I detail (in Section II and III) his polemic (...) engagement with Wolffian predecessors, and how he grounds collisions in a priori dynamics. I conclude that, for the young Kant, the philosophical problematic of Newton’s science takes a back seat to an agenda set by the Leibniz-Wolff tradition of rationalist dynamics. This results matters, because Kant’s views on motion survive well into the 1780s. In addition, his doctrine attests to the richness of early modern views of the relativity of motion. (shrink)

SummaryThis paper attempts to develop an interpretation of Kant's transcendental idealism which is based upon his critique of transcendental realism . It is argued that given Kant's transcendental distinction, all non‐ or pre‐critical philosophies, even Berkeleian phenomenalism are transcendentally realistic. This paradoxical result is used as the basis for an analysis of Kant's resolution of the mathematical antinomies, wherein this resolution is seen both as an “indirect proof” of transcendental idealism and as a refutation of transcendental realism. (...) Finally, it is claimed that Kant's idealism, at least insofar as it is established by means of a refutation of transcendental realism, is methodological rather than metaphysical, viz. it involves a claim about how the sensible world is to be considered in transcendental reflection, not a claim about the “real nature” of this world.RésuméCet article essaye de développer une interprétation de l'idéalisme transcendental de Kant, interprétation basée sur sa critique du réalisme transcendental . L'auteur montre que, si l'on accepte la distinction transcendentale de Kant, toutes les philosophies non critiques et précritiques sont transcendentalement réalistes, y compris le phénoménalisme de Berkeley. A partir de ce résultat paradoxal, il analyse la manière dont Kant résoud les antinomies mathématiques: cette résolution apparaît à la fois comme preuve indirecte de l'idéalisme transcendental et comme une réfutation du réalisme transcendental. L'auteur est finalement d'avis que l'idéalisme de Kant, du moins lorsqu'il est justifié par une réfutation du réalisme transcendental, est plus méthodologique que métaphysique, c'est‐à‐dire qu'il déclare comment le monde sensible doit être considéré dans la réflexion transcendentale et non quelle est la véritable nature de ce monde.ZusammenfassungEs wird versucht, eine Interpretation von Kants transzendentalem Idealismus zu entwickeln, die auf seiner Kritik am transzendentalen Realismus — verstanden als derjenige Standpunkt, der systematisch Erscheinung und Ding an sich verwechselt — beruht. Es wird argumentiert, dass — einmal Kants transzendentale Unterscheidung angenommen — aile früheren, vorkritischen Systeme der Philosophie einschliesslich Berkeleys Phänomenalismus transzendental realistisch sind. Dieses paradoxale Ergebnis wird als Basis für eine Analyse von Kants Auflösung der mathematischen Antinomien verwendet, wobei dièse Auflösung sowohl als ein indirekter Beweis für den transzendentalen Idealismus als auch als eine Widerlegung des transzendentalen Realismus gedeutet wird. Es wird schliesslich nahegelegt, dass Kants Idealismus, sofern wenigstens als er sich auf Widerlegung des transzendentalen Realismus abstützt, mehr ein rnethodologischer als ein metaphysischer Idealismus ist. Er statuiert eher über die Art, wie die Sinneswelt in einer transzendentalen Reflexion betrachtet werden soll, als über die Frage, wie die Welt wirklich beschaffen sei. (shrink)

I raise three objections for Gava’s thesis that the primary task of the Critique of Pure Reason is to develop a doctrine of method for metaphysics, understood as an account of the special kind of unity that a body of cognitions must exhibit to count as a science. First, I argue that this thesis has difficulty accommodating Kant’s concern with explaining the possibility of synthetic a priori judgements. This concern is motivated by a question that is prior to the issue (...) of scientific unity. Second, I argue that the context of the passage in which Kant calls the Critique a treatise on method makes clear that the remark concerns the Copernican Turn. This suggests that the method treated in the book is the procedure required by the Copernican Turn. Third, I dispute Gava’s claim that the idea that confers unity on metaphysics is the cosmopolitan concept of philosophy. (shrink)

According to Kant, justifying the application of mathematics to objects in natural science requires metaphysically constructing the concept of matter. Kant develops these constructions in the Metaphysical Foundations of Natural Science (MAdN). Kant’s specific aim is to develop a dynamic theory of matter to replace corpuscular theory. In his Preface Kant claims completely to exhaust the metaphysical doctrine of body, but in the General Remark to MAdN ch. 2, “Dynamics,” Kant admits that once matter is reconceived as (...) basic forces, it is no longer possible to construct the concept of matter. I argue that Kant’s admission is only the tip of the problem, and that none of Kant’s commentators has fully grasped the problems infecting the MAdN that underlie Kant’s admission. I show that Kant’s proof that matter consists of forces is fallacious. I then re-analyze the circularity in Kant’s definition of density, criticizing both Adickes’ formulations and his later dissolution of it. I also show that a third circularity infects the relations between Kant’s treatment of “Dynamics” and “Mechanics” (MAdN ch. 3). These three fundamental problems demonstrate the untenability of Kant’s metaphysical method, and they require the radical revision of the relation between mathematics and metaphysics Kant undertakes in his opus postumum. I show that some of Kant’s most surprising and critical later claims about the Critical philosophy are correct, and that they require the sorts of remedies Kant contemplates in the opus postumum. (I defend the essentially correct analyses offered by Burkhard Tuschling and Eckart Forster against criticisms by Michael Friedman.). (shrink)

Many seventeenth- and eighteenth-century philosophers of the Enlightenment, such as Hobbes, Spinoza, Locke, Shaftesbury, Hume, Voltaire, and Diderot, criticized religious doctrines not only because (or when) such doctrines comprised unfounded claims to knowledge, but also because they inspired fanaticism, ensuing in sectarian violence, persecution, torture, and war. In this paper, I attempt to reconstruct Kant’s position, as part of this Enlightenment project: he too repeatedly and pejoratively characterizes various forms of belief in or behavior guided by religious (or other) (...) conceptions of the supersensible as “fanaticism” (Schwärmerei). By comparison to many Enlightenment figures, Kant’s understanding of the relation between the human presumption to knowledge of the supersensible and the deliverances of reason is more sympathetic to the claims of religious belief and more qualified in advocating the corrective power of reason against it. I argue that Kant’s conception of fanaticism – its origins, motivations, and the nature of its error – reflects this more qualified endorsement of reason. I suggest that by contrast to many of his predecessors and contemporaries Kant does not treat fanaticism as expressing or originating wholly from sensible emotions or interests, opposed to and “overpowering” reason. Rather, though sensibility (including emotional sensibility) is central to his account of fanaticism, Kant holds that the problematic fanatical stance incorporates and depends on rational projections or aspirations, particularly those of practical reason. Moreover, Kant’s distinction between theoretical and practical reason generates an interesting, dual account of fanaticism: theoretical fanaticism, a kind of cognitive error, and practical fanaticism, a specifically practical error in our relation to the supersensible.

Kant’s Theory of Moral Motivation examines the uniquely moral motive of respect in light of Kant’s general metaphysics of agency. Kant refers to respect as a “sui generis” feeling that is both intrinsically cognitive and conative, but also denies that respect is any kind of feeling at all. Guevara convincingly argues that the feelings characteristic of respect are not psychological effects caused by our recognition of the authority of the moral law: rather, such feelings are just the affective aspect of (...) this recognition itself, as it is realized in agents with both an intelligible and a sensible character. Guevara also argues that the affective side of respect is fundamentally “positive” in character, despite Kant’s claims that our immediate experience of the law is one of “humiliation,” in which our pretensions to self-worth independent of morality are struck down.

Karin de Boer’s Kant’s Reform of Metaphysics aims at reassessing the metaphysical impulse of the Critique of Pure Reason. The principal claim of the book is that Kant’s critical philosophy must be...

At the present time, there are several interpretations and modes of Kant’s transcendental philosophy (TP). Which of these interpretations and modes of transcendentalism most adequately express the spirit of TP, i.e. can claim the title of the transcendental ones? For the explication of the ‘idea of transcendental philosophy’ [KrV, A1], here I distinguish two transcendental shifts: methodological and metaphysical ones, which in their totality predetermine the essence and set the specificity of Kant’s transcendental idealism. The methodological transcendental shift that (...) Kant postulates in his definitions of TP in the Critique of Pure Reason [KrV, A11; B25] represents a shift from studying of objects to the analysis and justification of our mode of cognition of objects. This shift sets a fairly wide range of a la Kantian a priori doctrines and predetermines the transcendental turn (Re–Transcendentalising) of modern philosophy. The metaphysical transcendental shift that can be correlated with “the altered method of our way of thinking [in metaphysics]” [KrV, BXVIII], is associated with the splitting of the “thing” into the actual object (or Kantian thing-in-itself) and object of experience (or Kantian appearance), and involves a transition from the study of thing-in-itself to the analysis of the appearance. More precisely, this shift finds its expression in the transcendental triad “object (thing-in-itself; Ding an sich) – appearance (Erscheinung) – representation (Vorstellung)”, which determines the ‘idea’ (essence) of transcendental idealism/metaphysics.

Kant and Leibniz are interested in explaining how a number of individuals can come together and form a single unified composite substance. Leibniz does not have a convincing account of how this is possible. In his pre-critical writings and in his later metaphysics lectures, Kant is committed to the claim that the idea of a world is the idea of a real whole, and hence is the idea of a composite substance. This metaphysical idea is taken over into his (...) ethical writings and becomes the idea of a realm of ends. I explain why a realm of ends, should be thought of as both a unum per se and as a real whole. A realm of ends is a whole of individuals unified by laws they have given themselves, that is, it is a community of autonomous individuals. Only such a community can be thought of as a composite individual. Such a whole will be real rather than ideal because the source of the unity of the whole is intrinsic to the whole, for what gives unity to the realm are laws and the sources of the laws are the individual members of the whole. It will be a unum per se because both the laws and the individuals constituting the realm are incomplete without one another. If this reading is correct, this requires a fundamental reevaluation of Kant’s notion of autonomy. To be autonomous is not, primarily, to be understood in terms of ruling oneself, but instead must be thought of primarily in terms of being a generative source of laws for an ideal community.

one of kant's most famous claims is his dictum about existence. In the course of his criticism of the ontological argument, he writes:Being is obviously not a real predicate, i.e., a concept of something that could be added to the concept of a thing.One reason why this passage is so famous is that many people think that it anticipates a discovery about the logical form of existence claims that was later central for the development of analytic philosophy (...) and its project of overcoming metaphysical confusions by logical analysis. There are two prominent interpretations that read Kant's dictum along these lines. The first, and by far most popular, interprets Kant as holding a proto-Fregean view about existence.2... (shrink)

Henry E. Allison presents an analytical and historical commentary on Kant`s transcendental deduction of the pure concepts of the understanding in the Critique of Pure Reason. He argues that, rather than providing a new solution to an old problem, it addresses a new problem, and he traces the line of thought that led Kant to the recognition of the significance of this problem in his 'pre-critical' period. In addition to the developmental nature of the account of Kant`s views presented here, (...) two distinctive features of Allison's reading of the deduction are a defense of Kant`s oft criticized claim that the conformity of appearances to the categories must be unconditionally rather than merely conditionally necessary and an insistence that the argument cannot be separated from Kant`s transcendental idealism.

In my comments on Karin de Boer’s Kant’s Reform of Metaphysics, I pose five questions. First, I ask how the fundamental principle of practical philosophy that Kant identifies and claims is fundamentally different from Wolff’s is consistent with the claim that Kant is reforming Wolff’s metaphysics. Second, I ask whether De Boer thinks that Kant, as a reformer of Wolff, continues to accept the Principle of Sufficient Reason (or some variant thereof). Third, I ask whether De Boer accepts Wolff’s (...) conception of analytic judgements, especially as applied to the fundamental principles of metaphysics, and if she does not, how Kant can be reforming rather than rejecting Wolff’s metaphysics. Fourth, I ask what De Boer’s argument is for thinking that Kant is not begging the question against Wolff in thinking that a priori cognition needs schemata. Fifth, I ask how De Boer understands the division of labour between the Transcendental Analytic and the Transcendental Dialectic in establishing the claims of metaphysics. (shrink)

R. Lanier Anderson presents a new account of Kant's distinction between analytic and synthetic judgments, and provides it with a clear basis within traditional logic. He reconstructs compelling claims about the syntheticity of elementary mathematics, and re-animates Kant's arguments against traditional metaphysics in the Critique of Pure Reason.

Sally Sedgwick presents a fresh account of Hegel's critique of Kant's theoretical philosophy. She argues that Hegel offers a compelling critique of and alternative to the conception of cognition that Kant defended in his 'Critical' period, and explores Hegel's claim to derive from Kantian doctrines clues to a superior form of idealism.

This paper addresses problems associated with the role of the empirical concept of matter in Kant's Metaphysical Foundations of Natural Science, offering an interpretation emphasizing two points consistently neglected in the secondary literature: the distinction between logical and real essence, and Kant's claim that motion must be represented in pure intuition by static geometrical figures. I conclude that special metaphysics cannot achieve its stated and systematically justified goal of discovering the real essence of matter, but that Kant (...) requires this failure for his larger philosophical presentation of the dialectic that (A298/B354).

This volume of essays, written in English and German, focuses primarily on Kant's concept of transcendental freedom. The first Critique famously introduces this concept of freedom in the third antinomy, where Kant examines the apparent tension between the world's need for an uncaused cause and the world's thorough causal determination. Thus, Kant's concept of transcendental freedom is, as this volume emphasizes, a cosmological conception of freedom. Although the volume claims to consider Kant's conception of cosmological freedom (...) from both historical and systematic perspectives, the bulk of the essays focus more heavily on historical matters. Most of the essays in the volume compare and contrast Kant's conception of... (shrink)

In his lectures on Logic and Metaphysics, Kant distinguishes between logical and real essences. While the former is related to concepts and is knowable, the latter is related to things and is unknowable. In this paper, I argue that the unknowability is explained by the modal characteristic of real essences as a necessitating ground on which a priori knowledge is impossible. I also show how this claim is related to the unknowable necessity of particular laws of nature. Since laws of (...) nature are conceived as grounded in real essences, the unknowability of the latter is equivalent to Kant's other claim that there can be no knowledge of the necessity of particular laws of nature. Necessity can only be known a priori, and therefore, the necessity of particular laws is only assumed and conceived as grounded in something unknowable, a real essence. This conclusion will allow me to attribute to Kant a position I label as “regulative essentialism”, meaning that real essences have an indispensable role in accordance with the rational interest to explain nature as a system of laws and natural kinds, combined with an epistemic humility about the correspondence of our empirical concepts to real essences.

Kant's revolution in methodology limited metaphysics to the conditions of possible experience. Since, following Hume, analysis—the “method of discovery” in early modern physics—could no longer ground itself in sense or in God's constituting reason a new arché, “origin” and “principle,” was required, which Kant found in the synthesis of the productive imagination, the common root of sensibility and understanding. Charles Bigger argues that this imaginative “between” recapitulates the ancient Gaia myth which, as used by Plato in the Timaeus, offers (...) a way into this originary arché. Since it depends on myth and the “likely story” rather than on a self-certain apprehension of Being, this facilitates an imaginative approach to the natural sciences which, through its synthetic a priori formations, can claim to be Kantian. Bigger explores Kant's ethics as an alternative to metaphysics that holds open the prospect of a Good beyond Being—and phenomenology—whose traces nevertheless appear in original synthesis. Though wary of its reductive implications, Bigger uses Derrida's difference, a medial, feminine arché, as a way into this creative and procreative metaxu. As Emmanuel Levinas suggests, this is Plato's gap [chaos] between being and becoming, whose possibility, beyond both, lies in chora and the Good. This Open also presents the possibility for a new, yet still Kantian, understanding of the formal and material conditions for the natural sciences. (shrink)

THE PURE INTUITIONS OF SPACE AND TIME and the pure concepts of understanding are the two basic elements in Kant's critical philosophy. Whereas his account of pure intuitions is relatively straightforward, his theory of categories is quite complicated. When he presents space and time as two forms of intuition, he never sees the need to prove that there are no other forms of intuition than these two. But when he presents his table of categories, he tries to prove its (...) completeness in one of the most obscure chapters of the first Critique, known as the "Metaphysical Deduction." Kant complicates his picture of categories by claiming two different functions for them: the logical and the real. The obscurity surrounding the relation of these two functions is the chief obstacle for understanding the "Transcendental Deduction," perhaps the most controversial chapter of the Critique. He further aggravates the problem in the "Schematism," perhaps the most oracular chapter of the Critique, by producing a set of categories quite different from the original set given in the "Metaphysical Deduction.".

Schelling’s 1809 Freiheitsschrift, perhaps his most widely read work, presents considerable difficulties of understanding. In this paper, I offer an interpretation of the work in relation to Kant. My focus is on the relation in each case of their theory of human freedom to their general metaphysics, a relation which both regard as essential. The argument of the paper is in sum that Schelling may be viewed as addressing and resolving a problem which faces Kant’s theory of freedom and transcendental (...) idealism, deriving from the challenge posed by Spinozism. One major innovation in Schelling’s theory of human freedom is his claim that it presupposes the reality of evil. I argue that Schelling’s thesis concerning evil also provides a key to the new and highly original metaphysics of the Freiheitsschrift. The relation of Schelling’s theory of freedom to his general metaphysics is therefore complex, for it goes in two directions: the metaphysics are not simply presupposed by the theory of freedom but are also in part derived from it. These new metaphysics also, I argue, allow Schelling to resolve a problem which his own earlier Spinozistic system had left unresolved. (shrink)

Immanuel Kant claims that transcendental idealism yields a form of realism at the empirical level. Polite silence might best describe the reception this assertion has garnered among even sympathetic interpreters. This book challenges that prejudice, offering a controversial presentation and rehabilitation of Kant's empirical realism that places his realist credentials at the centre of the account of representation he offers in the Critique of Pure Reason. This interpretation ranges over the major themes contained in the Analytic of Principles (...) and relevant portions of the Dialectic. Kant's analysis of the conditions necessary for determinate representation is shown to involve a realist understanding of the relation of mind and world. The realist character of Kant's account of empirical truth, and his commitment to the unity of nature, are defended against competing empiricist, pragmatist, and methodological readings. This title links Kant studies to contemporary philosophical debates, and will appeal to scholars and students of Kant, as well as epistemologists, metaphysicians, and philosophers of science interested in a powerful, experience-sensitive, form of realism.

In ‘Kant’s Changing Cosmopolitanism’ and Kant and Cosmopolitanism: The Philosophical Ideal of World Citizenship, Pauline Kleingeld argues that, in ‘Idea for a Universal History with a Cosmopolitan Intent,’ Kant meant for the Bund of states to be a coercive federation. Kleingeld admits that there is a disparity between this earlier coercive idea of the Bund and Kant’s talk of a voluntary congress in Toward Perpetual Peace and The Metaphysics of Morals. She explains this disparity by: appealing to a semantic ambiguity (...) in the term ‘Bund’; making claims about with which contemporary 18th century works Kant was acquainted; and ultimately attempting to draw a parallel between the unsocial sociability of individual people within a state and the unsocial sociability of individual states in a larger community of states. In this paper, I argue that while Kleingeld’s claims are superficially supported by the text, her claims depend on her apparent conflating of teleology and morality. (shrink)

Kant’s avowed commitment to the basic principles of Leibniz’s metaphysics is evident throughout the critical project and stated explicitly in the Prize Essay. However, it is not until the Critique of Judgment, wherein Kant recognizes that Judgment operating in its reflective mood can engender synthetic a priori claims, that Kant is fully capable of appropriating the basic tenets of Leibniz’s metaphysics. This paper examines Kant’s treatment of Leibniz from the perspective of the Critique of Judgment. It is argued that (...) from this vantage point the metaphysics of Leibniz is viewed as fundamental for Kant’s critical project. Moreover, it is argued that it is not until the retrieval of Leibniz’s metaphysics that Kant has a basis for seeking the unity of pure and practical reason. (shrink)

This major study of Kant provides a detailed examination of the development and function of the doctrine of transcendental illusion in his theoretical philosophy. The author shows that a theory of 'illusion' plays a central role in Kant's arguments about metaphysical speculation and scientific theory. Indeed, she argues that we cannot understand Kant unless we take seriously his claim that the mind inevitably acts in accordance with ideas and principles that are 'illusory'. Taking this claim seriously, we can (...) make much better sense of Kant's arguments and reach a deeper understanding of the role he allots human reason in science. (shrink)

Andrew Chignell recently proposed an original reconstruction of Kant's ‘Only Possible Argument’ for the existence of God. Chignell claims that what motivates the ‘Grounding Premise’ of Kant's proof, ‘real possibility must be grounded in actuality’, is the requirement that the predicates of a really possible thing must be ‘really harmonious’, i.e. compatible in an extra-logical or metaphysical sense. I take issue with Chignell's reconstruction. First, the pre-Critical Kant does not present ‘real harmony’ as a general condition (...) of real possibility. Second, the real harmony requirement is not what motivates the ‘Grounding Premise’ of the proof. Instead, this premise is sufficiently motivated by what Chignell labels the ‘content’ requirement. Finally, Kant's downgrading of the proof in his Critical period is not based on a concern regarding the real harmony of the predicates of God, but on his Critical restrictions on cognition in general and modal cognition in particular.
