Kant: Transcendental Idealism

This essay discusses recent attempts to show that Kant's philosophy is coherent and consistent on its own terms. This paper was read at the annual POH Symposium in Lake Wenatchee, WA in May, 2013.

Kant’s doctrine of the “transcendental object” has always puzzled interpreters. On the one hand, he says that the transcendental object is the object to which we relate our representations. On the other hand, he declares the transcendental object to be unknowable and identifies it with the thing in itself. I argue that this poses a problem that Kant only in the B edition of the Critique solves in a satisfactory manner. According to this solution, we ascribe sensible predicates to things (...) in themselves, but only insofar as they appear. I conclude that this could motivate a phenomenalist account of Kant’s idealism, but one that gives due weight to the role of things in themselves. (shrink)

The paper offers a model of Kant's claim that unity of consciousness entails objectivity of experience. This claim has nothing especially to do with thought, language or the categories but is a general truth about arbitrary signaling systems of the sort modeled in the paper. In conclusion I draw some consequences for various forms of idealism.

Kant's A-Edition objective deduction is naturally (and has traditionally been) divided into two arguments: an " argument from above" and one that proceeds " von unten auf." This would suggest a picture of Kant's procedure in the objective deduction as first descending and ascending the same ladder, the better, perhaps, to test its durability or to thoroughly convince the reader of its soundness. There are obvious obstacles to such a reading, however; and in this chapter I will argue that the (...) arguments from above and below constitute different, albeit importantly inter-related, proofs. Rather than drawing on the differences in their premises, however, I will highlight what I take to be the different concerns addressed and, correspondingly, the distinct conclusions reached by each. In particular, I will show that both arguments can be understood to address distinct specters, with the argument from above addressing an internal concern generated by Kant’s own transcendental idealism, and the argument from below seeking to dispel a more traditional, broadly Humean challenge to the understanding’s role in experience. These distinct concerns also imply that these arguments yield distinct conclusions, though I will show that they are in fact complementary. (shrink)

Do plants represent according to Kant? This is closely connected to the question of whether he held plants are alive, because he explains life in terms of the faculty to act on one’s own representations. He also explains life as having an immaterial principle of self-motion, and as a body’s interaction with a supersensible soul. I argue that because of the way plants move themselves, Kant is committed to their being alive, to their having a supersensible ground of their self-activity, (...) and to their having desires (although these are not conscious). This has important ramifications for Kant’s teleology and philosophy of mind. (shrink)

In this review, I criticize aspects of Emanuel Rutten's new reading of Kant, which belongs to the radical phenomenalistic interpretations of Kant's idealism.

In this paper I address a structurally similar tension between phenomenalism and realism about matter in Leibniz and Kant. In both philosophers, some texts suggest a starkly phenomenalist view of the ontological status of matter, while other texts suggest a more robust realism. In the first part of the paper I address a recent paper by Don Rutherford that argues that Leibniz is more of a realist than previous commentators have allowed. I argue that Rutherford fails to show that Leibniz (...) is any less an idealist than his main target, Robert Merrihew Adams, does. I distinguish various kinds of idealism about bodies that Leibniz might have held, and attempt to determine which package of views represents his considered view. In the second part of the paper I situate Kant’s idealism within the same coordinates. I argue that, abstracting from deep differences in their metaphysics and epistemology, Kant and Leibniz have structurally very similar views on the ontological status of matter and bodies. I conclude that the key to understanding the realist strand in their ontology of matter is understanding the way in which, for both thinkers, the forces in bodies are appearances of forces of more fundamental entities, either monads or things in themselves.

Asymmetry theories about free will and moral responsibility are a recent development in the long history of the free will debate. To my knowledge, Kant commentators have not yet explored the possibility of an asymmetrical reconstruction of Kant's theory of freedom, and that will be my goal here. By "free will", I mean the sort of control we would need to be morally responsible for our actions. Kant's term for it is "transcendental freedom", and he refers to the attribution of (...) moral responsibility as "imputation". By "Kant's theory of freedom", I mean not only his theory of transcendental freedom and imputation, but also the various ways in which he draws on these ideas in his moral theory. (shrink)

The problem of synthetic judgements touches on the question of whether philosophy can draw independent statements about reality in the first place. For Kant, the synthetic judgements a priori formulate the conditions of the possibility for objectively valid knowledge. Despite the principle fallibility of its statements, modern science aims for objective knowledge. This gives the topic of synthetic a priori unbroken currency. This paper aims to show that a modernized version of transcendental philosophy, if it is to be feasible at (...) all, must “bid farewell” to the concept of being “free of empiricism” or the “purity” of the a priori. Approaches to this end can already been found in Kant’s reflections on non-pure synthetic knowledge. Moreover, the a priori validity of knowledge does not exclude the possibility that it can be discovered empirically. In keeping with Kant, Fries and Nelson anticipated this separation (usually first attributed to Reichenbach) between the validity and discovery context of knowledge and pointed out that the a priori could be discovered empirically, but never proven. There are currently still good reasons why transcendental philosophical concepts are of fundamental importance for modern science, although it must not be overlooked that even within the framework of a modernized transcendental philosophy, several unsolved problems remain or are raised. For example, the irredeemability of the universal validity and necessary claims of the a priori, the problem of a clear demarcation between the phenomenal and noumenal world. Moreover, the “beautiful structure” or the Kantian system, which constituted its persuasive power, is lost. (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.

In this paper, we draw attention to several important tensions between Kant’s account of moral education and his commitment to transcendental idealism. Our main claim is that, in locating freedom outside of space and time, transcendental idealism makes it difficult for Kant to both provide an explanation of how moral education occurs, but also to confirm that his own account actually works. Having laid out these problems, we then offer a response on Kant’s behalf. We argue that, while it might (...) look like Kant has to abandon his commitment to either moral education or transcendental idealism, there is a way in which he can maintain both. (shrink)

The author considers ethical and legal aspects of a developing of AI systems. He examines the ethical aspect through the prism of Kant’s philosophy and outlines moral prospects of (quasi)intelligent robots. The author considers the legal aspect in context of normative regulation of risks that arise with a creating of AI systems. In conclusion the author makes an assumption on forthcoming transformation of a legal system because of a new type of legal acts that combine classical form of legal act (...) and machine protocol. -/- В статье затрагиваются этический и правовой аспекты развития систем искусственного интеллекта. Этический аспект автор рассматривает с позиций философии И. Канта и обрисовывает нравственные перспективы создания (квази)разумных роботов. Правовой аспект рассматривается в контексте нормативного регулирования рисков, возникающих при создании систем ИИ. В заключении делается предположение о грядущей перестройке правовой системы в связи с возникновением нового типа НПА, которые сочетают в себе классическую форму НПА и машинного протокола. (shrink)

The article discusses some facts of C. G. Jung's direct appeal to the ideas of I. Kant. The main part of the article is preceded by statistical data on the mention of various philosophers in the Collected Works of Jung. It is not surprising that Kant leads in the number of links to his ideas or personality in Jung’s heritage. Then I show examples of the mention of Kant in Jung’s correspondence, which allow understand the fundamental philosophical background of analytical (...) psychology better. For this purpose in particular I give excerpts from which it becomes clear that the creator of the analytical psychology, unlike his predecessor C. G. Carus, never hypostasized the collective unconscious, because Jung believed that this is a thing in itself. Also by correspondence it is clear that Jung grasped Kant’s criticism of the rational proofs of existence of God well. Then I point out how apriorism is manifested in analytical psychology. Also I explain briefly how to understand that archetypes and instincts are necessary a priori conditions for the formation of psychic experience. In conclusion, the reasons are given for which Kant and Jung rejected the fundamental possibility of the existence of psychology in the status of strict science. -/- В статье рассматриваются некоторые факты прямого обращения К. Г. Юнга к идеям И. Канта. Основная часть статьи предваряется статистическими данными по упоминанию различных философов в 20-томном академическом собрании сочинений Юнга. Совершенно не удивительно, что по количеству ссылок лидирует Кант. Далее приводятся конкретные примеры упоминания родоначальника немецкой классической философии в переписке Юнга, что позволяет лучше понять фундаментальную философскую подоплёку аналитической психологии. Так, приводятся отрывки, из которых становится ясно, что создатель аналитической психологии, в отличие от своего предшественника К. Г. Каруса, никогда не гипостазировал коллективное бессознательное, считая, что это вещь в себе. Также по переписке видно, что Юнг усвоил произведённую Кантом критику доказательств бытия Божия. Затем в статье указывается, каким образом в аналитической психологии проявляется априоризм. Кратко объясняется, как следует понимать то, что архетипы и инстинкты являются необходимыми априорными условиями формирования психического опыта. В заключение приводятся основания, по которым Кант и Юнг отвергали принципиальную возможность существования психологии в статусе строгой науки, и которые до сих пор не преодолены. (shrink)

Interpreters of Kant’s Refutation of Idealism face a dilemma: it seems to either beg the question against the Cartesian sceptic or else offer a disappointingly Berkeleyan conclusion. In this article I offer an interpretation of the Refutation on which it does not beg the question against the Cartesian sceptic. After defending a principle about question-begging, I identify four premises concerning our representations that there are textual reasons to think Kant might be implicitly assuming. Using those assumptions, I offer a reconstruction (...) of Kant’s Refutation that avoids the interpretative dilemma, though difficult questions about the argument remain. (shrink)

This article presents a metaphysical approach to the interpretation of the role of things-in-themselves in Kant’s theoretical philosophy. This focuses upon identifying their transcendental function as the grounding of appearances. It is interpreted as defining the relation of appearing as the grounding of empirical causality. This leads to a type of dual-aspect account that is given further support through a detailed examination of two sections of Kant’s first Critique. This shows the need to embed this dual-aspect account within a two-perspective (...) framework. The resulting picture is contrasted with the main rival theories and objections are addressed.

Over the last two decades, Kant’s name has become closely associated with the “constitutivist” program within metaethics. But is Kant best read as pursuing a constitutivist approach to meta- normative questions? And if so, in what sense? In this essay, I’ll argue that we can best answer these questions by considering them in the context of a broader issue – namely, how Kant understands the proper methodology for philosophy in general. The result of this investigation will be that, while Kant (...) can indeed be read as a sort of constitutivist, his constitutivism is ultimately just one instance of a much more general approach to philosophy – which treats as fundamental our basic, self-conscious rational capacities. Thus, to truly understand why and how Kant is a constitutivist, we need to consider this question within the context of his more fundamental commitment to “capacities-first philosophy”. (shrink)

I examine here if Kant can explain our knowledge of duration by showing that time has metric structure. To do so, I spell out two possible solutions: time’s metric could be intrinsic or extrinsic. I argue that Kant’s resources are too weak to secure an intrinsic, transcendentally-based temporal metrics; but he can supply an extrinsic metric, based in a metaphysical fact about matter. I conclude that Transcendental Idealism is incomplete: it cannot account for the durative aspects of experience—or it can (...) do so only with help from a non-trivial metaphysics of material substance.

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.

It is well known that Kant seeks to discredit rational psychology on the grounds that we cannot access the nature of the soul by reflecting upon the ‘I think’ of self-consciousness. What is far less understood, however, is why Kant still believes the theorems of rational psychology are analytically true insofar as they represent the ‘I’ through the categories of substance, reality, unity, and existence. Early post-Kantian thinkers like Fichte would abandon this restriction and approach the concept of the ‘I’ (...) instead through the category of community or reciprocal interaction. The result was nothing less than a radical shift in thinking about persons after Kant, yet in a way that would bear a striking affinity to the substance monism of Spinoza. The aim of this chapter is to trace the origin of this shift and its aftermath in Fichte’s effort to defend a new conception of the ‘I’. (shrink)

In A Realist Theory of Science, Roy Bhaskar provides several transcendental arguments for critical realism – a position Bhaskar himself characterized as transcendental realism. Bhaskar provides an argument from perception and from the intelligibility of scientific experimentation, maintaining that transcendental realism is necessary for both. I argue that neither argument succeeds, and that transcendental idealism can better vindicate scientific practice than Bhaskar’s realism. Bhaskar’s arguments against the Kantian view fail, for they misrepresent the transcendental idealist position. I conclude that, if (...) they wish to retain their theoretical commitments, critical realists ought to be transcendental idealists. (shrink)

Chapter 4 of Dennis Schulting’s book Kant’s Radical Subjectivism targets those commentators who take there to be a gap in the transcendental deduction of the categories, arguing instead that there is no gap between the necessary application of the categories and their exemplification in the object of experience. In these comments on the chapter, I suggest a minimal sense in which the fact that there is a gap is non-negotiable. The interesting question is not whether there is a gap which (...) needs to be bridged, but how and why Kant makes the step from subjectivity to objectivity. (shrink)

This article examines the relationship between the conspicuous and complicated terms of transcendence and immanence, which may equally be defined as essentially connected, or diametrically opposed. Recent developments in two largely unrelated sets of scholarship— the re-evaluation of secularisation, and the relationship between medieval and modern philosophy—provide a helpful means to arrive at a clearer understanding of this challenging problem. Charles Taylor and Jan Aertesn act as foci for these developments, particularly through their respective concerns with epistemic framing in relation (...) to transcendence and immanence, and the role of transcendentals in medieval philosophy. This examination brings these two concepts together, examining the idea of transcendentals offered by both Aquinas, a thinker of the transcendent frame, and Kant, a thinker of the immanent frame. From this juxtaposition we can offer two contrasting understandings of the relationship between transcendence and immanence from within both the transcendent and immanent frames. Finally, two brief literary examples demonstrate how these two ways of reading transcendence and immanence may be employed in the contextual understanding of religious writing. To understand the unity and division between transcendence and immanence is to better comprehend two primary terms in the study of religion, and to appreciate a fundamental development in the history of religion in the West.

O'Shea concludes that Sellars's attempts to preserve the core truths in Kant's theory of experience and to integrate them with an overall scientific naturalist outlook can and should survive the rejection of several central components of Sellars's proposed adaptation of Kant's transcendental idealism: ABSTRACT: "Sellars’ career-long engagement with Kant’s philosophy involved both readings of Kant and appropriations of Kant that are nuanced, original, and related in complex ways to Sellars’ own philosophical views. In some ways similar to Strawson’s classic reading, (...) Sellars defended Kant’s theory of experience and his analysis of human knowledge as essentially correct. This includes various views on the nature of conceptual cognition, the thinking self, practical reason, perceptual experience, and the lawfulness of nature. On the other hand, and again like Strawson, Sellars regarded Kant’s transcendental idealism as involving a strong ontological commitment to unknowable but thinkable (and non-spatiotemporal) ‘things in themselves’. However, whereas Strawson regarded such a position as deeply incoherent, Sellars argues that Kant’s theological conception of things in themselves can coherently be replaced with a scientific realist conception of things in themselves as theoretically postulated imperceptible processes, which play a structurally similar role for Sellars in grounding the Kantian-phenomenal ‘appearances’ in the ‘manifest image’ of the world. Sellars’ highly complex but sophisticated reading of Kant on sensibility and intuition, when combined with Sellars’ own idiosyncratic views on sensory qualia, render it even more difficult to come to terms with Sellars’ engagements with Kant’s idealism. This chapter attempts to provide a concise presentation and evaluation of certain central themes in Sellars’ complex philosophical dialogue with Kant.". (shrink)

In this article, I respond to critiques of my book Kant’s Radical Subjectivism: Perspectives on the Transcendental Deduction (London: Palgrave Macmillan, 2017). I address issues that are raised concerning objectivity, the nature of the object, the role of transcendental apperception and the imagination, and idealism. More in particular I respond to an objection against my reading of the necessary existence of things in themselves and their relation to appearances. I also briefly respond to a question that relates to the debate (...) on Kantian nonconceptualism, more in particular, the question whether Kant allows animals objective intentionality. Lastly, I respond to one objection against my reading of Hegel’s critique of Kant. (The copy uploaded here is an English translation of the original Dutch version that is published in the journal.).

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 study aims to show a similarity of Kant’s and Jung’s approaches to an issue of the possibility of scientific psychology, hence to explicate what they thought about the future of psychology. Therefore, the article contains heuristic material, which can contribute in a resolving of such methodological task as searching of promising directions to improve philosophical and scientific psychology. To achieve the aim the author attempts to clarify an entity of Kant’s and Jung’s objections against even the possibility of scientific (...) psychology and to find out ways to overcome those objections in Kant’s and Jung’s works. The main methods were explication, reconstruction and comparative analysis of Kant’s and Jung’s views. As a result it was found, that Kant and Jung allocated one and the same obstacles, which, on their opinion, prevent psychology to become a science in the strict sense. They are: 1) coincidence of subject and object in psychology; 2) impossibility to apply quantitative mathematic methods in psychology; 3) pendency of the issue of psychophysical parallelism. However, Kant and Jung indicated ways to resolve formulated by them fundamental difficulties. All those ways lay through the searching a principle of interaction and connection between the psychic and the physical. (shrink)

In the introduction to the Critique of Pure Reason (2nd edition), Kant claims that a transcendental cognition is a one ‘that is occupied not so much with objects but rather with our mode of cognition of objects insofar as is this ought to be possible a priori (a priori möglich sein soll)’. In this paper, I argue that Kant scholarship should take into account the specific signification of the term ‘sollen’, which might require us to reconsider the usual distinction between (...) the system of freedom and the system of nature. Following a Fichtean perspective, I will try to show that, even if ‘sollen’ in this context does not refer to a duty in the strict sense, it does refer to the demand that transcendental philosophy itself be possible. I will argue that this demand is contingent at its very origin and, accordingly, expresses a particular kind of ‘freedom’. On this basis I will consider the tribunal of reason enacted in the Critique of Pure Reason as a tribunal that emerges from a free decision, in which the transcendental philosopher imagines its own possibility. Because it is a ‘free’ and ‘contingent’ tribunal, it cannot exceed the status of a problematic philosophical strategy. (shrink)

Lucy Allais seeks to provide a reading of the Transcendental Deduction of the Categories which is compatible with a nonconceptualist account of Kant’s theory of intuition. According to her interpretation, the aim of the Deduction is to show that a priori concept application is required for empirical concept application. I argue that once we distinguish the application of the categories from the instantiation of the categories, we see that Allais’s reconstruction of the Deduction cannot provide an answer to Hume’s problem (...) about our entitlement to use a priori concepts when thinking about the objects of empirical intuition. If the Deduction is to provide a response to Hume, Allais’s interpretation must be rejected. (shrink)

Phenomenalist interpretations of Kant are out of fashion. The most common complaint from anti-phenomenalist critics is that a phenomenalist reading of Kant would collapse Kantian idealism into Berkeleyan idealism. This would be unacceptable because Berkeleyan idealism is incompatible with core elements of Kant’s empirical realism. In this paper, I argue that not all phenomenalist readings threaten empirical realism. First, I distinguish several variants of phenomenalism, and then show that Berkeley’s idealism is characterized by his commitment to most of them. I (...) then make the case that two forms of phenomenalism are consistent with Kant’s empirical realism. The comparison between Kant and Berkeley runs throughout the paper, with special emphasis on the significance of their theories of intentionality. (shrink)

In this paper we look at a few of the most prominent ways of articulating Kant’s critical argument for Noumenal Ignorance — i.e., the claim that we cannot cognize or have knowledge of any substantive, synthetic truths about things-in-themselves — and then provide two different accounts of our own.

Ott (2009) identifies two kinds of philosophical theories about laws: top-down, and bottom-up. An influential top-down reading, exemplified by Ernst Cassirer, emphasized the ‘mere form of law’. Recent bottom-up accounts emphasize the mind-independent natures of objects as the basis of laws of nature. Stang and Pollok in turn focus on the transcendental idealist elements of Kant’s theory of matter, which leads to the question: is the essence of Kantian matter that it obeys the form of law? I argue that Kant (...) has an independent theory of matter in the Metaphysical Foundations of Natural Science, one that gives what Kant himself calls a ‘real definition’ of matter as a theory-independent (if not mind-independent) entity. I argue that this matter theory underpins physical arguments about inertia and impenetrability, which resemble Einstein’s arguments about the unification of fields in general relativity. (shrink)

In this chapter, I show that there is at least one crucial, non-short, argument, which does not involve arguments about spatiotemporality, why Kant’s subjectivism about the possibility of knowledge, argued in the Transcendental Deduction, must lead to idealism. This has to do with the fact that given the implications of the discursivity thesis, namely, that the domain of possible determination of objects is characterised by limitation, judgements of experience can never reach the completely determined individual, i.e. the thing in itself (...) or the unlimited real, but only objects as objects of possible experience. As such, it can be shown by reference to a key argument from Kant, that Hegel’s famous criticism that Kant is not licensed, on the basis of his core arguments concerning the original-synthetic unity of apperception, to restrict our knowledge to appearances, is mistaken on purely systematic grounds. More specifically, I argue that idealism follows already from the constraints that the use of the categories, in particular the categories of quality, places on the very conceivability of things in themselves. My claim is that, although it is not only possible but also necessary to think things in themselves, it does not follow that by merely thinking them we have a full grasp of the nature of things in themselves, as some important commentators claim we have. We must therefore distinguish between two kinds of conceiving of things in themselves: conceiving in the standard sense of ‘forming the notion of’, and conceiving in the narrow sense of ‘having a determinate intellectual grasp’. So although we must be able notionally to think things in themselves, as the grounds of their appearances, we cannot even conceive, through pure concepts, of how they are in themselves in any determinate, even if merely intellectual, sense. To put it differently, we cannot have a positive conception of things in themselves (this is in line with Kant’s distinction between noumena in the negative and positive senses; cf. B307–9). For support, I resort to a much overlooked chapter in the Critique, concerning the transcendental Ideal, where Kant discusses what it is for a thing to be a thing in itself proper, namely, something that is thoroughly determined. This concerns the real ontological conditions of things, which are not satisfied by the modal categories alone, namely, their existence conditions. I claim that the chief reason why, given Kant’s view of determinative judgement, we cannot determine a thing in itself is because of two connected reasons: (1) a thing in itself is already fully determined and therefore not further determinable and (2) we cannot possibly determine all of the thing’s possible determinations. In this context, I also discuss the notion of material (not: empirical) synthesis—of which Kant speaks in the chapter on the transcendental Ideal—which must be presupposed as the ground of the formal a priori synthesis that grounds possible experience. This material synthesis, which is an idea of reason that defines a thing as thoroughly determined with regard to all of its possible predicates and has mere regulative status, can by implication not be determined by the forms of the understanding, which synthesise only a limited set of predicates. As a result, given this definition of ‘thing in itself’, any object (appearance) as at best44 a limited set of determinations of the thing can never be numerically identical to the thing in itself as thoroughly determined individual. This undercuts a standard assumption about the identity relation between appearances and things in themselves in many contemporary interpretations of Kant’s transcendental idealism. (shrink)

Researchers often talk about a powerful heuristic potential of the Kantian heritage, but sometimes they do not show concrete examples in defense of this opinion outside Kantianism and Neo- Kantianism. This article contains an attempt to demonstrate that on the example of how efficiently C.G. Jung used Kant’s ideas to construct the theoretical basis of analytical psychology in general and his conception of archetypes in particular, we can see the urgency of Kant’s heritage not only for his direct spiritual successors. (...) In addition the question is discussed: why did Jung claim that epistemologically he took his stand on Kant? (shrink)

The distinction of things in themselves and appearances is an integral part of Kant’s transcendental idealism, yet it has often been met with rather significant hostility. Moreover, what surely has not contributed to the popularity of this Kantian doctrine is that there are, or at least there appear to be, two distinct models, detectable in Kant’s texts, to account for this distinction. Most commonly, these two models are called the “two aspect view” on the one hand and the “two world (...) view” on the other, but it is possible that these labels themselves invite misunderstandings and obscure rather than clarify what Kant had in mind with his distinction. In this paper, I shall first briefly discuss how these two models could be described and labelled in a more suitable manner, namely as the “one composite entity view” and the “two separate objects view”. Subsequently, I will enquire which of the models is pertinent for Kant’s solution to the 3rd antinomy. I will try to show that although the two models appear to be incompatible, it is at least plausible to read Kant as using both of them in this crucial text of his oeuvre. Moreover, Kant’s strategy in solving the freedom problem on the basis of an indirectly realist account of the divine intellect provides the clue to understanding how these seemingly incompatible models can co-exist without forcing Kant into maintaining contradictory claims.

According to “intentionalist” interpretations of Kant’s transcendental idealism, Kant’s empirical objects are to be understood as mere intentional objects. This interpretation requires a corresponding account of intentionality and intentional objects. This paper defends an account of how the intentionalist should understand the intentional structures at work in the sensory consciousness of physical bodies. First a relational conception of intentionality (articulated in terms of an object’s presence to consciousness) is distinguished from a non-relational conception (articulated in terms of representational content). I (...) argue that the intentionalist’s claim that Kant’s empirical objects are mere intentional objects is primarily a claim about non-relational intentionality. I then ask whether the intentionalist should also recognize a role for relational intentionality as well. After rejecting two possible answers (that there is no relational intentionality, or that there are intentional relations to things in themselves), I argue that sensory consciousness involves having spatially arrayed collections of sensations presented to consciousness in intuition, and then conceptualizing these sensation-arrays as physical objects. The obvious worry about such a phenomenalist interpretation has to do with the consistency of this interpretation with Kant’s empirical realism; these concerns are addressed in detail in the final section.

Extended critical discussion of Lucy Allais, *Manifest Reality*.

I argue that Kant’s commitment to the existence of things in themselves takes the form of a commitment short of knowledge that does not violate the limitations on knowledge which he lays down. I will argue that Kant’s commitment fits his description of what he calls “doctrinal belief”: acceptance of the existence of things in themselves which is subjectively sufficient but not objectively sufficient. I outline two ways in which we accept the existence of things in themselves which are subjectively (...) sufficient. First, we must accept the existence of appearances, which requires us to accept the existence of things in themselves. Second, we must accept the existence of an unconditioned ground of appearances.

This study focuses on the essential difference between Kant’s and Husserl’s transcendental Idealism. In fact, Husserl describes in the «Cartesian Meditations» his own ontological thesis as a «transcendental idealism», in which all sorts of entities have to be constituted by an activity of the transcendental subjectivity, so that we have to regard pure consciousness as the ontological origin of all entities in the world. But this study is interested in the two opposite signications of the Kantian copernican inversion. On the (...) one hand, the Copernican inversion has the same sense as the phenomenological reduction, which implies that Husserl can’t agree with Kant’s presupposition of absolute things in themselves; on the second hand, it involves a relativistic and anthropologistic orientation, so that the aprioristic structures of given objects are founded on the universal structures of finite subjectivity, on pure forms and faculties of human consciousness. At the opposite, Husserl enounces a methodological prescription for any phenomenological elucidation: it is not allowed to presuppose in phenomenology any given faculty or given nature of transcendental subjectivity. This prescription has important consequences on which this study focuses. First the ontological difference between intuitus originarius and intuitus derivatus, in nite and nite type of intuition, doesn’t have any validity: the difference between factual and rational truths only depends on the essence of the truth itself, and doesn’t have its foundation on the ontological difference between creative and receptive sort of intuition. Secondly, this first thesis admits an immediate application on the level of subjective constitution of objects: the modality in which an object appears to the subjectivity doesn’t depend on the universal structure of finite subject, but is exclusively founded on the essence of the object itself, so that it is impossible to consider the aprioristic constitutive structure as a merely subjective structure. Thirdly, in this transcendental phenomenology everything has to be constituted by subjectivity: the aprioristic character of the pure forms of sensibility is not founded on the structure of finite subjectivity, but rather on the essential connection between sensual material and form; so that it is not allowed to presuppose any facticity of time and space; the pure forms of sensibility have to be constituted by a special type of synthesis that we have to elucidate in opposition to other types of higher levels. The profound signication of Husserl’s anticopernican inversion is that the field of transcendental phenomenology consists of the essential form of an eidos ego, which is «more objective than any objectivity», as Levinas said; and that transcendental phenomenology is completely dominated by the principium reddendae rationis.

There is substantial textual evidence that Kant held the doctrine of double affection: subjects are causally affected both by things in themselves and by appearances. However, Kant commentators have been loath to attribute this view to him, for the doctrine of double affection is widely thought to face insuperable problems. I begin by explaining what I take to be the most serious problem faced by the doctrine of double affection: appearances cannot cause the very experience in virtue of which they (...) have their empirical properties. My solution consists in distinguishing the sense of ‘experience’ in which empirical objects cause experience from the sense of ‘experience’ in which experience determines empirical objects. I call the latter “universal experience”. I develop my conception of universal experience, and then I explain how it solves the problem of double affection. I conclude by addressing several objections. (shrink)

It is often claimed that anti-realism is a form of transcendental idealism or that Kant is an anti-realist. It is also often claimed that anti-realists are committed to some form of knowability principle and that such principles have problematic consequences. It is therefore natural to ask whether Kant is so committed, and if he is, whether this leads him into difficulties. I argue that a standard reading of Kant does indeed have him committed to the claim that all empirical truths (...) are knowable and that this claim entails that there is no empirical truth that is never known. I extend the result to a priori truths and draw some general philosophical lessons from this extension. However, I then propose a re-examination of Kant’s notion of experience according to which he carefully eschews any commitment to empirical knowability. Finally I respond to a remaining problem that stems from a weaker, justified believability principle. (shrink)

The chapter discusses Quentin Meillassoux's recent interpretation and critique of Heidegger's philosophical position, which he describes as "strong correlationism." It emphasizes the fact that Meillassoux situates Heidegger in the post-Kantian tradition of transcendental idealism that he defines in terms of a focus on the correlation between being and thinking. It is argued that Meillassoux's "speculative" attempt to overcome the Kantian philosophical framework in the name of absolute contingency should be understood as a further development and dialectical overcoming of its ultimate (...) contemporary form, the Heideggerian philosophy of finitude.

Publications in the Kant-Studien have a dual focus: firstly contributions to the interpretation, history and editorial questions of Kant’s philosophy, and secondly systematic debates on transcendental philosophy. In addition, there are investigations on Kant’s precursors and on the effects of his philosophy. The journal also contains a documentation section, in which the current state of research is indicated by means of a continually updated bibliography with reviews and references.

It has recently been suggested that Merleau-Ponty’s position in Phenomenology of Perception is a unique form of transcendental idealism. The general claim is that in spite of his critique of “Kantianism,” Merleau-Ponty’s position comes out as a form of transcendental idealism that takes the perceptual processes of the lived body as the transcendental constituting condition for the possibility of experience. In this article I critically appraise this claim. I argue that if the term “idealist” is intended in a sufficiently similar (...) sense to Kant’s usage of the term in naming his position as a “transcendental idealism” then it is a misrepresentation to subsume Merleau-Ponty’s position under that term. This is because Merleau-Ponty rejects the transcendental metaphysics of the reflecting subject that underpins transcendental idealism. In its place he advocates a methodological transcendentalism that, whilst being anti-realist, is not idealist. Thus to call his position “a new kind of transcendental idealism,” as Sebastian Gardner has, is to misunderstand the significance of his existentialist break with what he sees as the “intellectualism” of this position.

Despite his impressive influence on nineteenth-century philosophy, F. A. Trendelenburg's own philosophy has been largely ignored. However, among Kant scholars, Trendelenburg has always been remembered for his feud with Kuno Fischer over the subjectivity of space and time in Kant's philosophy. The topic of the dispute, now frequently referred to as the ?Neglected Alternative? objection, has become a prominent issue in contemporary discussions and interpretations of Kant's view of space and time. The Neglected Alternative contends that Kant unjustifiably moves from (...) the claim that we have a priori intuitions of space and time to the sceptical conclusion that space and time are exclusively subjective. Most current discussions trace the objection back to Trendelenburg and often use him to motivate the objection. However, to date Trendelenburg's actual arguments and reasons for rejecting the Kantian view of space and time have not been sufficiently uncovered; my goal here is to fill this lacuna. By better understanding what Trendelenburg actually argued, we will be in a better position to assess whether the Neglected Alternative objection against Kant is successful. But in addition, Trendelenburg's own system is of independent philosophical interest, and my work here will shed light on one part of it. (shrink)

This paper is concerned with some aspects of Kant’s transcendental idealism, in particular the claim that objects of experience are nothing but representations in us, and its connection to the distinction of things in themselves and appearances. This claim has prompted phenomenalist readings which have rightly been rejected almost unanimously. Instead it has been suggested to account for Kant’s distinction in terms of mind-dependent or subject-relativized properties and properties which are not mind-dependent or subject-relativized. Along this line, the “nothing but (...) representation”-claim is then sometimes understood in terms of the secondary-quality analogy, which Kant endorses in the Prolegomena, but rejects in the first Critique. As an alternative, I attempt to interpret Kant along the lines of Suárez’s formal/objective distinction and Scotus’s modal explication of being. (shrink)

Kant’s transcendental idealism hinges on a distinction between appearances and things in themselves. The debate about how to understand this distinction has largely ignored the way that Kant applies this distinction to the self. I argue that this is a mistake, and that Kant’s acceptance of a single, unified self in both his theoretical and practical philosophy causes serious problems for the ‘two-world’ interpretation of his idealism.

The one-world interpretation of Kant's idealism holds that appearances and things in themselves are, in some sense, the same things. Yet this reading faces a number of problems, all arising from the different features Kant seems to assign to appearances and things in themselves. I propose a new way of understanding the appearance/thing in itself distinction via an Aristotelian notion that I call, following Kit Fine, a ‘qua-object.’ Understanding appearances and things in themselves as qua-objects provides a clear sense in (...) which they can be the same things while differing in many of their features.

This publication defends a phenomenalist interpretation of Kant’s idealism, which, however, deviates from usual phenomenalist interpretations in several respects. According to my reading, appearances are the content of representations, but not the true object of cognition. The object to which our cognition refers is rather the thing itself as the transcendental object. Nonetheless, we only cognize them as they appear and not as they are in themselves. Thus the unknowability of things as they are in themselves is retained. In the (...) course of my presentation, I discuss a number of aspects of Kant’s philosophy, among which are the distinction between appearances and things in themselves, Kant’s relationship to Cartesian epistemology, the refutation of idealism, and not least his theory of synthesis. My aim is not only to show that Kant is a phenomenalist, but also to characterize the kind of his phenomenalism. (shrink)
