Kant: Metaphysics

In this critical review of Robert Hanna's ingenious book (2006), I aim to support Hanna‟s main insightful reading of Kant, namely what he calls “a priori truth with a human face," without appealing to Kant's divide between a priori and a posteriori and analytic and synthetic truths. My suggestion is that transcendental propositions are necessary neither in the usual epistemological sense that analytic propositions are, let alone in the metaphysical sense that some empirical propositions are. Instead, they are necessary in (...) the theoretical domain in the weak alternative sense that they make possible the empirical recognition of appearances as an object as an indispensable condition of our self-consciousness experience, and they are a priori in the practical domain in the sense that their truth is vital for our self-comprehension as human beings.

Our aim in this chapter is to shed light on Kant’s account of the pure forms of sensibility by focusing on a somewhat neglected issue: Kant’s restriction of his claims about space and time to the case of human sensibility. Kant argues that space and time are the pure forms of sensibility for human cognizers. But he also says that we cannot know whether space and time are likewise the pure forms of sensibility for all discursive cognizers. A great deal (...) of attention has focused on the first of these claims, both on how Kant argues for it and how it relates to transcendental idealism. But a satisfactory interpretation must also account for the second claim, and it must account for the fact that Kant endorses both of them. What we need is an explanation of why Kant thinks our knowledge that space and time are the pure forms of sensibility extends to all human beings but no further. (shrink)

In this issue of Studies in Transcendental Philosophy five scholars enquire about the theoretical aspects of Kant’s transcendental philosophy related to the notions of subject, self-consciousness, and self-knowledge. Andrew Brook examines Kant’s views on transcendental apperception at the end of the Critical Period, focusing on Opus Postumum which contains some of Kant’s most important reflections on the subjective dimension. As is known, the self-conscious act designated by the proposition ‘I think’ is an act of spontaneity, and this spontaneity is the (...) reason that the subject calls itself an intelligence. In his article Addison Ellis examines the theoretical and practical dimension of spontaneity, calling into question the distinction between a merely ‘relative’ spontaneity and one that is ‘absolute’. Luca Forgione points to two forms of self-consciousness introduced by Kant: inner sense, based on a sensory form of self-awareness, and transcendental apperception. Through the notion of inner sense, Kant also allows for an introspective account of self-awareness; nonetheless, Kant holds an utterly sophisticated notion of basic self-consciousness provided for by the notion of transcendental apperception. Roberto Horácio de Sá Pereira’s article presents a systematic and a historical approach, linking the contemporary debate on transcendental argument to Kant’s philosophy. It addresses both Stroud’s objection and Strawson’s perspective on transcendental argument and introduces a new reconstruction of Kant’s Refutation as successful truth-directed transcendental argument. In contrast to the contemporary movement of transhumanism and its claims that creatures like us can exist independently of our bodies, Robert Hanna develops a generalist perspective on the subjective dimension, according to which all rational human creature are synthetic a priori necessarily, essentially embodied Kantian selves. I would like to thank the authors for participating in this issue and for helping to make it really special. (shrink)

Esta edição contém a única transcrição estudantil sobrevivente das Lições de Metafísica de Kant da década de 1770. A Lição foi ministrada o mais tardar no inverno de 1779/80 e, portanto, antes mesmo da publicação da Crítica da Razão Pura (1781). Um exceção é, contudo, a parte sobre a ontologia que seguramente se remonta a uma Lição que Kant ministrou depois de 1781. Estas transcrições de Lições são de valor inestimável para a história do desenvolvimento da filosofia de Kant e, (...) em especial, para a gênese de sua Crítica da Razão Pura . Elas representam também um complemento importante para suas outras Lições, como por exemplo, as de antropologia, nas quais Kant também se ocupou com as questões da psicologia empírica e racional. É interessante observar que Kant se serve de métodos distintos, nas Lições de Antropologia e de Metafísica, para demonstrar a substancialidade e a imortalidade da alma. Embora Kant ainda leve a doutrina da alma da psicologia racional muito a sério na Metafísica-Pölitz, ele rejeitará de fato suas pretensões de conhecimento pouco tempo depois na Crítica na seção sobre os paralogismos da doutrina pura da alma. Aquele que deseja se aprofundar na filosofia de Kant e conhecer seu contexto histórico-filosófico não pode deixar de ler as Lições de Metafísica-Pölitz. Heiner F.

In recent years, nonconceptual content theories have seen Kant as a reference point for his notion of intuition (§§ 1-3). This work aims to dismiss the possibility that intuition is provided with an autonomous function of de re knowledge. To this end, it will explore certain epistemological points that emerge from Garroni’s reading of the Third Critique in the conviction that they provide a suitable context to verify the presence of autonomous, epistemically nonconceptual content in the transcendental system (§§ 4-5). (...) It is here, in fact, that Kant discusses those cases where intuition is given without bringing into play the conceptual component. As Garroni posits, in this frame of reference, such content cannot subsist without the interplay between aesthetic and conceptual dimensions (§§ 6-7). Long before the development of the debate on Kantian nonconceptualism, and during the period in which the Kantian debate on the epistemic considerations contained in the Third Critique was developing deeply for the first time, Garroni had already identified a theoretical position on these issues, which can be labelled aesthetic conceptualism, thanks to his fundamentally epistemological reading of the Third Critique.

There is a confounding issue at the very heart of philosophical reflection. It is the question of where, and in what sense, the bounds of intelligible thought, knowledge, and speech are to be drawn. To inquire into these limits is to acknowledge that we are “finite thinking beings,” as Kant puts it. Indeed, one way of understanding our essentially problematic position in the world which leads us into philosophy is to view it as a position of being fated to the (...) perpetual attempt to reckon with the limits of intelligibility: we are creatures for whom it can become a live question how to make sense of thought, action, knowledge, the good life, the nature of self-consciousness, mortal existence, and so forth – and where this sense-making gives out. This introductory essay puts special emphasis on the ways in which we might fall prey to a confused and pernicious kind of self-deception or self-alienation in seeking a philosophical remedy to the limits of intelligibility. In modern times, no other thinkers have faced up to this troubling possibility of self-alienation with the same rigor and in such depth as Kant and Wittgenstein. (shrink)

The deduction of categories in the 1781 edition of the Critique of the Pure Reason (A Deduction) has “two sides”—the “objective deduction” and the “subjective deduction”. Kant seems ambivalent about the latter deduction. I treat it as a significant episode of Kant’s thinking about categories that extended from the early 1770s to around 1790. It contains his most detailed answer to the question about the origin of categories that he formulated in the 1772 letter to Marcus Herz. The answer is (...) that categories are generated a priori through a kind of intellectual “epigenesis”. This account leaves unexplained why precisely such and such categories should be generated. While this observation caused Kant to worry about the hypothetical status of the subjective deduction in 1781, he would come to acquiesce in the recognition that the ground of the possibility of categories is itself inscrutable. I call this his “methodological skepticism”. (shrink)

This paper draws out and connects two neglected issues in Kant’s conception of a priori knowledge. Both concern topics that have been important to contemporary epistemology and to formal epistemology in particular: knowability and luminosity. Does Kant commit to some form of knowability principle according to which certain necessary truths are in principle knowable to beings like us? Does Kant commit to some form of luminosity principle according to which, if a subject knows a priori, then they can know that (...) they know a priori? I defend affirmative answers to both of these questions, and by considering the special kind of modality involved in Kant’s conceptions of possible experience and the essential completability of metaphysics, I argue that his combination of knowability and luminosity principles leads Kant into difficulty. (shrink)

The of aim of this paper is to enquire about some theoretical aspects of Kant’s philosophy that are connected to the representation ‘I’ and the question of self-identification in self-consciousness. The subjective capacity to represent itself through the representation ‘I’ will be articulated on the basis of the structure the so-called de se or I-thoughts developed by Perry and Recanati. In this regard, a contrast between Longuenesse’s view and my approach on self-identification and the different uses of I as subject (...) will be considered. (shrink)

For Kant, the human cognitive faculty has two sub-faculties: sensibility and the understanding. Each has pure forms which are necessary to us as humans: space and time for sensibility; the categories for the understanding. But Kant is careful to leave open the possibility of there being creatures like us, with both sensibility and understanding, who nevertheless have different pure forms of sensibility. They would be finite rational beings and discursive cognizers. But they would not be human. And this raises a (...) question about the pure forms of the understanding. Does Kant leave open the possibility of discursive cognizers who have different categories? Even if other discursive cognizers might not sense like us, must they at least think like us? We argue that textual and systematic considerations do not determine the answers to these questions and examine whether Kant thinks that the issue cannot be decided. Consideration of his wider views on the nature and limits of our knowledge of mind shows that Kant could indeed remain neutral on the issue but that the exact form his neutrality can take is subject to unexpected constraints. The result would be an important difference between what Kant says about discursive cognizers with other forms of sensibility and what he is in a position to say about discursive cognizers with other forms of understanding. Kantian humility here takes on a distinctive character. (shrink)

A revised version of this paper became chapter I of Kant's Critical Religion.

The goal of this paper is to better understand Kant’s conception of philosophy as a “world concept”, which is at the heart of the Architectonic of Pure Reason. This is pursued in two major parts. The first evaluates the textual foundation for reading Kant’s world concept of philosophy as cosmopolitanism and concludes that he most probably never himself equated philosophy as a world concept with any form of cosmopolitanism. The second major part of the paper clarifies this concept of philosophy (...) through the specific role it plays in the argument of the Architectonic. Kant’s unique concept of science is examined and compared with several specific applications of it found elsewhere in Kant’s writings. From this it is concluded that Kant’s intention in the Architectonic was to derive his world concept of philosophy from its logical counterpart, namely the scholastic concept of philosophy, and that its function there is to provide the idea from which the entire structure of Kantian critical metaphysics can be derived. Philosophy as a world concept, it is further argued, is the complete system of critical or Kantian metaphysics in application and the philosopher in this sense is the ideal critical metaphysician who fully realizes its laws through her own understanding and will.

Dictionary entry of "Idealism" in the "New Dictionary of the History of Ideas".

The aim of this paper is to address the semantic issue of the nature of the representation I and of the transcendental designation, i.e., the self-referential apparatus involved in transcendental apperception. The I think, the bare or empty representation I, is the representational vehicle of the concept of transcendental subject; as such, it is a simple representation. The awareness of oneself as thinking is only expressed by the I: the intellectual representation which performs a referential function of the spontaneity of (...) a thinking subject. To begin with, what exactly does Kant mean when he states that I is a simple and empty representation? Secondly, can the features of the representation I and the correlative transcendental designation explain the indexical nature of the I? Thirdly, do the Kantian considerations on indexicality anticipate any of the semantic elements or, if nothing else, the spirit of the direct reference theory? (shrink)

I recently argued that critical realists ought to adopt transcendental idealism in favour of Bhaskar’s transcendental realism. In response, Dustin McWherter presents two arguments against transcendental idealism: it is inferior to transcendental realism because it cannot account for the epistemic significance of experimentation, and it is internally inconsistent because it affirms the existence of things-in-themselves. This brief reply defends transcendental idealism against both objections.

This book addresses the problem of self-knowledge in Kant’s philosophy. As Kant writes in his major works of the critical period, it is due to the simple and empty representation ‘I think’ that the subject’s capacity for self-consciousness enables the subject to represent its own mental dimension. This book articulates Kant’s theory of self-knowledge on the basis of the following three philosophical problems: 1) a semantic problem regarding the type of reference of the representation ‘I’; 2) an epistemic problem regarding (...) the type of knowledge relative to the thinking subject produced by the representation ‘I think’; and 3) a strictly metaphysical problem regarding the features assigned to the thinking subject’s nature. The author connects the relevant scholarly literature on Kant with contemporary debates on the huge philosophical field of self-knowledge. He develops a formal reading according to which the unity of self-consciousness does not presuppose the identity of a real subject, but a formal identity based on the representation ‘I think’.

How does the critical Kant view ontology? There is no shared scholarly answer to this question. Norbert Hinske sees in the Critique of Pure Reason a “farewell to ontology,” albeit one that took Kant long to bid (Hinske 2009). Karl Ameriks has found evidence in Kant’s metaphysics lectures from the critical period that he “was unwilling to break away fully from traditional ontology” (Ameriks 1992: 272). Gualtiero Lorini argues that a decisive break with the tradition of ontology is essential to (...) Kant’s critical reform of metaphysics, as is reflected in his shift from “ontology” to “transcendental philosophy,” two notions that Lorini takes to be related by mere “analogy” (Lorini 2015). I agree with Lorini that a thorough reform of ontology is a pivotal part of Kant’s critical plan for metaphysics and that ontology somehow “survives within the critical philosophy” (Lorini 2015: 76). To make this case, however, I deem it important to identify “ontology” and “transcendental philosophy” in the sense of extensional equivalence. While we can detect this identification in Kant’s writings, only from his metaphysics lectures can we get a full sense of its historical and philosophical significance. In this chapter I focus on how it represents a definitive turn from as well as notable continuity with traditional treatments of ontology, particularly the Wolffian one. (shrink)

The concepts of particular and universal have grown so familiar that their significance has become difficult to discern, like coins that have been passed back and forth too many times, worn smooth so their values can no longer be read. On the Genealogy of Universals seeks to overcome our sense of over-familiarity with these concepts by providing a case study of their evolution during the late nineteenth century and early twentieth century, a study that shows how the history of these (...) concepts is bound up with the origins and development of analytic philosophy itself. Understanding how these concepts were taken up, transfigured, and given up by the early analytic philosophers, enables us to recover and reanimate the debate amongst them that otherwise remains Delphic. This book begins from the early, originating texts of analytic philosophy that have hitherto baffled commentators, including Moore's early papers, and engages afresh with the neglected contributions of philosophical figures that historians of analytic philosophy have mostly since forgotten, including Stout and Whitehead. This sheds new light upon the relationships of Moore to Russell, Russell to Wittgenstein, and Wittgenstein to Ramsey. (shrink)

Kant’s “transcendental” or “critical” philosophy is an instance of what can be called the “critique of immediacy.” As part of his critical project, Kant argues that one cannot merely assume that there is a reestablished harmony between thought and being. Instead, one must effect a “return to the subject” and examine the forms of thought themselves, in order to determine the extent to which thought and being are commensurable. As a result of his “transcendental turn,” Kant concludes that what at (...) first appears as immediately given to thought is always already (at least partly) the result of some kind of activity or mediation on the part of the thought itself. Hegel approves of Kant’s critical orientation: Kant correctly demanded to know “how far the forms of thought were capable of leading to the knowledge of truth,” and correctly concluded that “the forms of thought must be made into an object of investigation.” However, for Hegel, the problem with Kant was that he aimed to examine the forms of thought as if they were necessarily separated from being itself. Thus the Kantian strategy, for Hegel, led to a twofold absurdly. (shrink)

Das vorliegende Buch stellt die publizierte Fassung der Dissertation (Köln 2004) Elena Ficaras dar. Wie der Titel bereits zeigt, bewegt sich die Arbeit auf dem Feld transzendentaler Grundlagenarbeit und sucht die Ontologie, so wie Kant diese trotz aller Vorwürfe der Metaphysikfeindlichkeit neu begründet, zu erarbeiten.

On 18th century Kant found the Swedenborg's writings, and then wrote an aggressive refutation titled "The dream of a visionary". But Kant did not understand the Swedenborg experience and theories really. Because his rationalism he was unable to do that. This paper analyse the Kant's argumentation and shows its weak points and his inadequacy.

In the Transcendental Aesthetic (TA), Kant is typically held to make negative assertations about “things in themselves,” namely that they are not spatial or temporal. These negative assertions stand behind the “neglected alternative” problem for Kant’s transcendental idealism. According to this problem, Kant may be entitled to assert that spatio-temporality is a subjective element of our cognition, but he cannot rule out that it may also be a feature of the objective world. In this paper, I show in a new (...) way how Kant’s view (focusing on his conclusions about space) is not subject to this objection, by showing that he does not make the denial about mind-independent reality that he is typically held to make. The argument develops consequences of a new reading of Kant’s expression “an sich selbst” (‘in itself’; ‘in themselves’). I argue that “an sich selbst” or “per se” has a special, judgment-level role, so that this expression does not form new noun-terms adjectivally. It follows that the conceptual unit of Kant’s “Conclusions” in the TA is simply “things” (Dinge), since “things in themselves” is not a nominal expression; Kant adopts the Wolffian ontological use of “thing” as the basic kind-term for any existent. The arguments that things per se are not in space are arguments that space cannot be a necessary property or relations of things as a kind. I show that this does not involve the positive claim about mind-independent reality that inspires the neglected alternative objection. (shrink)

Draft for presentation at the 14th International Kant-Congress, September 2024. -/- Abstract: Kant claims we intuit infinite space. There’s a problem: Kant thinks full awareness of infinite space requires synthesis—the act of putting representations together and comprehending them as one. But our ability to synthesize is finite. Tobias Rosefeldt has argued in a recent paper that Kant’s notion of decomposing synthesis offers a solution. This talk criticizes Rosefeldt’s approach. First, Rosefeldt is committed to nonconceptual yet determinate awareness of (potentially) infinite (...) space, but I argue that such awareness is (1) prima facie implausible, as well as contravened by textual evidence from Kant’s (2a) definitions of ‘infinity’ and (2b) account of geometrical construction. Second, scrutiny of how Kant thinks awareness of potential infinity is afforded by geometrical construction (e.g., extending a line segment ad indefinitum) indicates no essential role for decomposing synthesis. Familiar synthesis from parts to wholes is sufficient. (shrink)

Famously, Kant describes space and time as infinite “given” magnitudes. An influential interpretative tradition reads this as a claim about phenomenological presence to the mind: in claiming that space and time are given, this reading holds, Kant means to claim that we have phenomenological access to space and time in our original intuitions of them. In this paper, I argue that we should instead understand givenness as a metaphysical notion. For Kant, space and time are ‘given’ in virtue of three (...) related facts: (i) they are necessary grounds of the existence of all other spatial and temporal possibilities; (ii) in virtue of being such grounds, they are metaphysically linked to all other represented spatiotemporal things; and (iii) as representations, space and time issue from the nature of our faculty of sensibility rather than from an arbitrary act of choice. Understanding givenness in this non-epistemological way helps us recover what is plausible in both ‘intellectualist’ and ‘anti-intellectualist’ readings of the Transcendental Aesthetic. Anti-intellectualists are correct that space and time are given in mere sensibility, but intellectualists are correct that we depend on the understanding for consciousness of space and time.

This chapter discusses Kant's 1763 "possibility proof" for the existence of God. I first provide a reconstruction of the proof in its two stages, and then revisit my earlier argument according to which the being the proof delivers threatens to be a Spinozistic-panentheistic God—a being whose properties include the entire spatio-temporal universe—rather than the traditional, ontologically distinct God of biblical monotheism. I go on to evaluate some recent alternative readings that have sought to avoid this result by arguing that the (...) relevant facts about real modality can be ultimately grounded in God’s powers or thoughts – or that Kant just leaves the grounding relations mysterious. I argue that the textual and philosophical costs of each of these alternative readings are formidable. The chapter concludes with a discussion of the fate of the proof in the critical period. Some commentators think that it disappears altogether, or that it is downgraded such that it produces a mere regulative idea of God as the most real being. I suggest that the proof survives but that the mode of assent it licenses towards its conclusion changes from knowledge to a certain kind of Belief (Glaube). (shrink)

Scholars working on Kant’s Anticipations of Perception generally attribute to him an argument that invalidly infers that objects have degrees of intensive magnitude from the premise that sensations do. I argue that this rests on an incorrect disambiguation of Kant’s use of Empfindung as referring to the mental states that are our sensings, rather than the objects that are thereby sensed. Kant’s real argument runs as follows. The difference between a representation of an empty region of space and/or time and (...) a representation of that same region as occupied by an object entails that, in addition to their extensive magnitude, objects must be represented as having a matter variable in intensive magnitude. Since it is the presence of sensation in a cognition that marks the difference between representing only the extensive magnitude of the object and the object as a whole, it is sensation that represents its intensive magnitude.

Il principale obiettivo teoretico di questo lavoro consiste nel tentativo di verificare, attraverso un’indagine storico-genealogica e concettuale, come nella filosofia di Gilles Deleuze si assista ad un radicale mutamento del paradigma relativo alla nozione di trascendentale. Si tratta, in altre parole, di ripercorrere alcune delle tappe fondamentali che conducono il filosofo parigino a “purificare” il trascendentale da ogni riferimento ad una coscienza soggettiva egologica che si fondi in quanto principio genetico del mondo. Si riterrà utile procedere analizzando, in primo luogo, (...) il rapporto che Deleuze intrattiene con le istanze originarie del soggettivismo trascendentale kantiano, ove il trascendentale stesso, nel pensiero del filosofo tedesco, è strettamente connesso all’Io penso in quanto facoltà appercettiva dell’intelletto che incarnerebbe le condizioni di possibilità dell’esperienza. In secondo luogo, si tratterà di orientarsi nel dibattito critico che Deleuze intrattiene con la fenomenologia di Edmund Husserl, ed in particolar modo con la lettura husserliana della Critica della Ragion Pura di Kant, ove il padre fondatore dell’indirizzo fenomenologico novecentesco è colui che fa leva sullo stretto rapporto che sussiste tra il trascendentale e la coscienza. Nonostante il percorso storico, tracciato dal concetto di trascendentale, abbia inizio con l’opera di Kant, ritengo non sia possibile evitare un pur breve confronto con il ruolo che l’ego ha avuto nella formulazione cartesiana del cogito; si dovrà, per ciò stesso, considerare la particolare lettura deleuziana che riconosce nel cogito cartesiano il “luogo” in cui confluiscono tutte le facoltà del soggetto, permettendo di identificare il cogito stesso con una forma embrionale di piano di immanenza, seppur non adeguatamente radicalizzata nella misura in cui il cogito cartesiano resta saldamente ancorato al soggetto. Ritengo, tuttavia, che il più considerevole obiettivo di questa proposta d’indagine non si risolva in una ricostruzione meramente storico-genealogica. Si tratterà, al contrario, di verificare come l’importanza degli esiti raggiunti da Deleuze mediante l’opera di purificazione della nozione di trascendentale sia da individuare su due fronti: 1. La teorizzazione del concetto di campo trascendentale permette a Deleuze di disegnare una forma di temporalità non psicologica e non cronologica fondata sul paradosso secondo cui il tempo costituirebbe un’interiorità non psicologica, o per meglio dire, una dimensione autenticamente trascendentale nella quale il soggetto vive e diviene. 2. In antitesi ai proponimenti della fenomenologia husserliana, l’esito autentico del progetto di purificazione del trascendentale da ogni istanza egologica consiste nell’interruzione della correlazione a priori tra il soggetto e il mondo, nella destituzione della filosofia da ogni pregiudizio antropocentrico, e nella rideterminazione dell’umano niente più che come un effetto, o un caso, del mondo.

Leibniz’s main thesis regarding the nature of space is that space is relational. This means that space is not an independent object or existent in itself, but rather a set of relations between objects existing at the same time. The reality of space, therefore, is derived from objects and their relations. For Leibniz and his successors, this view of space was intimately connected with the understanding of the composite nature of material objects. The nature of the relation between space and (...) matter was crucial to the conceptualization of both space and matter. In this paper, I discuss Leibniz’s account of relational space and examine its novel elaborations by two of his successors, namely, the young Immanuel Kant and the Croat natural philosopher Roger Boscovich. Kant’s and Boscovich’s studies of Leibniz’s account lead them to original versions of the relational view of space. Thus, Leibniz’s relational space proved to be a philosophically fruitful notion, as it yielded bold and intriguing attempts to decipher the nature of space and was a key part in innovative scientific ideas.

This essay examines the relationship between monads and space in Kant’s early pre-critical work, with special attention devoted to the question of ubeity, a Scholastic doctrine that Leibniz describes as “ways of being somewhere”. By focusing attention on this concept, evidence will be put forward that supports the claim, held by various scholars, that the monad-space relationship in Kant is closer to Leibniz’ original conception than the hypotheses typically offered by the later Leibniz-Wolff school. In addition, Kant’s monadology, in conjunction (...) with God’s role, also helps to shed light on further aspects of his system that are broadly Leibnizian, such as monadic activity and the unity of space.

By transcendental aesthetic, Kant means “the science of all principles of a priori sensibility” (A 21/B 35). These, he argues, are the laws that properly direct our judgments of taste (B 35 – 36 fn.), i.e. our aesthetic judgments as we ordinarily understand that notion in the context of contemporary art. Thus the first part of the Critique of Pure Reason, entitled the Transcendental Aesthetic, enumerates the necessary presuppositions of, among other things, our ability to make empirical judgments about particular (...) works of art. These presuppositions are sensible rather than intellectual because on Kant’s view, all intellection that considers objects of any kind, whether abstract or concrete, must at base connect to actual, material objects with which we come into direct contact; and this we can do only through sensibility (A 19/B 33). Thus the following discussion explores what Kant claims must be true of us in order to make the sorts of aesthetic judgments we make, rather than any particular class or quality of aesthetic judgments itself. On Kant’s view, what must be true of us in order to make aesthetic judgments is not different from what must be true of us in order to make any other kind of judgment about empirical objects.

This is a defense of Kant against the allegedly neglected alternative in his formulation of transcendental idealism. What sets it apart from the contributions of others who have spoken for Kant in this regard is the construction of a general interpretive framework — a reconstruction of the one Kant provides for transcendental idealism — as opposed to the development of an ad hoc defensive strategy for refuting the charges. Hence, comprehensive clarification instead of pointed rebuttal. The difference is between focusing (...) on the text and focusing on the problem. No doubt, doing both is not only possible but also required, as the problem is supposed to be in the text, but the point is that it is not there, and further, that we need not go anywhere else to show that it is not there. Thus, the approach is constructive rather than defensive, or more accurately, constructive as well as defensive. And the construction rests on what Kant actually said rather than on what he might have meant or on what he should have said instead. (shrink)

This is the introduction to the volume Kantian Nonconceptualism (Palgrave 2016).

: 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 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)

In this paper I consider Tetens' reaction to Kant's Inaugural Dissertation in his two most important philosophical works, the essay “Über die allgemeine speculativische Philosophie” of 1775 and the two-volume Philosophische Versuche of 1777. In particular, I focus on Tetens’ critical discussion of Kant's account of the acquisition of concepts of space and time.

El capítulo introduce al debate sobre la naturaleza del espacio entre Leibniz y Clarke/Newton y a la posición que adopta Kant más tarde. En particular, se exponen los dos principales argumentos de Leibniz, basados en los Principios de Razón Suficiente e Identidad de Indiscernibles, en favor del relacionismo así como algunas respuestas de Clarke/Newton. También se presenta el argumento basado en la orientación del espacio que propuso Kant en 1768 para refutar el relacionismo de Leibniz. Se concluye con una breve (...) exposición del idealismo trascendental de Kant en su Primera Crítica. (shrink)

In this article it is shown that a careful analysis of Kant 's Gedanken von der wahren Schätzung der lebendigen Kräfte und Beurtheilung der Beweise leads to a conclusion that does not match the usually accepted interpretation of Kant 's reasoning in 1747, according to which the young Kant supposedly establishes a relationship between the tridimensionality of space and Newton's law of gravitation. Indeed, it is argued that this text does not yield a satisfactory explanation of space dimensionality, and actually (...) restricts itself to justifying the tridimensionality of extension. (shrink)

In Van Cleve's "Problems from Kant," it is suggested that his interpretation of Kant's metaphysics resolves the problem of "The Neglected Alternative"--the worry that Kant failed to consider that space and time, while perhaps necessary for sensible intuition, could also be objectively real in-themselves. However, it is far from clear how Van Cleve is supposed to have solved this objection. This paper examines why Van Cleve might have thought the problem resolved on his view, and argues that there is no (...) reason to think the problem has in fact been resolved. (shrink)

Newton had a fivefold argument that true motion must be motion in absolute space, not relative to matter. Like Newton, Kant holds that bodies have true motions. Unlike him, though, Kant takes all motion to be relative to matter, not to space itself. Thus, he must respond to Newton’s argument above. I reconstruct here Kant’s answer in detail. I prove that Kant addresses just one part of Newton’s case, namely, his “argument from the effects” of rotation. And, to show that (...) rotation is relative to matter, Kant changes the meaning of ‘relative motion.’ However, that change puts Kant’s doctrine in deep tension with Newton’s science. Based on my construal, I correct earlier readings of Kant by John Earman and Martin Carrier. And, I argue that we need to revise Michael Friedman’s influential view of Kant. Kant’s struggle, I conclude, illustrate the difficulties that early modern relationists faced as they turned down Newtonian absolute space ; and it typifies their selective engagement with Newton’s case for it.

Mit dem Terminus 'ursprünglicher Raum' wird der Raum bezeichnet, der Kant innerhalb der transzendentalen Ästhetik als reine subjektive Form der Anschauung des äußeren Sinnes bestimmt. Man könnte ihn auch den 'ästhetischen Raum' nennen. Auf jeden Fall muss er vom (proto-)geometrischen Raum unterschieden werden, da letzterer eine Einheit voraussetzt die auf einer Synthesis beruht, und dadurch – weil bei Kant alle Synthesis unter den Kategorien steht – weniger ursprünglich zum Anschauungsvermögen gehört. Es ist diese Unterscheidung zwischen dem ursprünglichen Raum, der „Form (...) der Anschauung“ ist, und dem (proto-)geometrischen Raum, der „formale Anschauung“ ist, auf die Kant in einer bekannten Fußnote im §26 der transzendentalen Deduktion der B-Auflage anspielt. -/- Die Bedeutung der Unterscheidung zwischen (proto-)geometrischem und ursprünglichem Raum liegt unter anderem darin, dass sie stipuliert, dass das ursprüngliche Wesen des Raumes vor und unabhängig von dem erreichbar ist, was durch jedwede Mathematik der Ausdehnung von ihm ausgesagt wird. Das bedeutet nun aber nicht, dass diese Unterscheidung uns zwingt, anzunehmen, dass das ursprüngliche Wesen des Raumes auch von uns erreichbar ist. Und nehmen wir mal an, dass wir tatsächlich über eine Art Zugang zu diesem Wesen verfügen, dann noch stellt sich überdies die Frage, ob ein solcher Zugang sich innerhalb der Sphäre der Erkenntnis befindet, mit anderen Worten: ob das ursprüngliche Wesen des Raumes vom Philosophen auch wirklich erkannt – das heißt: in Erkenntnisurteile gefasst und ausgedrückt – werden kann.

I argue that Kant’s distinction between the cognitive roles of sensibility and understanding raises a question concerning the conditions necessary for objective representation. I distinguish two opposing interpretive positions—viz. Intellectualism and Sensibilism. According to Intellectualism all objective representation depends, at least in part, on the unifying synthetic activity of the mind. In contrast, Sensibilism argues that at least some forms of objective representation, specifically intuitions, do not require synthesis. I argue that there are deep reasons for thinking that Intellectualism is (...) incompatible with Kant's view as expressed in the Transcendental Aesthetic. We can better see how Kant’s arguments in the first Critique may be integrated, I suggest, by examining his notion of the 'unity' [Einheit] of a representation. I articulate two distinct ways in which a representation may possess unity and claim that we can use these notions to integrate Kant’s arguments in the Aesthetic and the Transcendental Deduction without compromising the core claims of either Sensibilism or Intellectualism—that intuition is a form of objective representation independent of synthesis, and that the kind of objective representations that ground scientific knowledge of the world require synthesis by the categories.
