Incongruent counterparts are pairs of objects which cannot be enclosed in the same spatial limits despite an exact similarity in magnitude, proportion, and relative position of their parts. Kant discerns in such objects, whose most familiar example is left and right hands, a “paradox” demanding “demotion of space and time to mere forms of our sensory intuition.” This paper aims at an adequate understanding of Kant’s enigmatic idealist argument from handed objects, as well as an understanding of its relation to (...) the other key supports of his idealism. The paper’s central finding is that Kant’s idealist argument from incongruent counterparts rests essentially on his theory of freedom. The surprising result sheds new light on deep and overlooked links among the pillars of transcendental idealism, pointing the way to a comprehensive and unified reading of Kant’s system of idealist arguments.

The nature of Kant’s criticism of his pre-Critical ‘possibility proof’ for the existence of God, implicit in the account of the Transcendental Ideal in the Critique of Pure Reason, is still under dispute. Two issues are at stake: the error in the proof and diagnosis of the reason for committing it. I offer a new way to connect these issues. In contrast with accounts that locate the motivation for the error in reason’s interest in an unconditioned causal ground of all (...) contingent existence, I argue that it lies in reason’s interest in another kind of unconditioned ground, collective unity. Unlike the conception of the former, that of the latter directly explains the problematic ontological assumption of the possibility proof, the existence of intelligible objects as the ground of possibility. I argue that such Platonic entities are assumed because they are amenable to the kind of unity prescribed by reason. However, since the interest in collective unity has a legitimate regulative use when applied to the systematic unity of nature, the conception of God entailed by the possibility proof is retained as a regulative idea of reason.

Realism takes many forms. The aim of this paper is to show that the “Critique of pure Reason” is the founding document of realism and that to the present-day Kant’s discussion of realism has shaped the theoretical landscape of the debates over realism. Kant not only invents the now common philosophical term ‘realism’. He also lays out the theoretical topography of the forms of realism that still frames our understanding of philosophical questions concerning reality. The paper explores this by analysis (...) of Kant’s methodological procedure to distinguish between empirical and transcendental realism. This methodological procedure is still of great help in contemporary philosophy, although it has its limits. (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)

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)

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.

The Bounds of Logic presents a new philosophical theory of the scope and nature of logic based on critical analysis of the principles underlying modern Tarskian logic and inspired by mathematical and linguistic development. Extracting central philosophical ideas from Tarski’s early work in semantics, Sher questions whether these are fully realized by the standard first-order system. The answer lays the foundation for a new, broader conception of logic. By generally characterizing logical terms, Sher establishes a fundamental result in semantics. Her (...) development of the notion of logicality for quantifiers and her work on branching are of great importance for linguistics. Sher outlines the boundaries of the new logic and points out some of the philosophical ramifications of the new view of logic for such issues as the logicist thesis, ontological commitment, the role of mathematics in logic, and the metaphysical underpinning of logic. She proposes a constructive definition of logical terms, reexamines and extends the notion of branching quantification, and discusses various linguistic issues and applications. (shrink)

I begin by considering a question that has driven much scholarship on transcendental idealism: are appearances numerically identical to the things in themselves that appear, or numerically distinct? I point out that much of the debate on this question has assumed that this is equivalent to the question of whether they are the same objects, but go on to provide textual, historical, and philosophical evidence that “object” (Gegenstand) and “thing” (Ding) have different meanings for Kant. A thing is a locus (...) of intensively gradable causal force, reality. I argue that appearances and things in themselves are not identical as objects, because the very concept of object-identity is tied, for Kant, to the concept of an intellect that would cognize the numerical identity of the objects in question. Because no intellect can be both discursive and intellectual, no intellect could cognize the numerical identity of objects across the phenomenal/noumenal divide, and thus the claim that they are identical has no content. However, the very same things, the same reality, can be given to our sensible intellects, and to divine intuitive intellect, as two non-overlapping domains of objects. Identity readers are thus shown to be right about the same thing relation, while non-identity readers are vindicated on the numerical identity of objects. (shrink)

In this article I respond to Sacha Golob's critique of my stance on Kantian nonconceptualism, objectivity, and animal perception of spatial particulars.

In this paper, I discuss the debate on Kant and nonconceptual content. Inspired by Kant’s account of the intimate relation between intuition and concepts, McDowell (1996) has forcefully argued that the relation between sensible content and concepts is such that sensible content does not severally contribute to cognition but always only in conjunction with concepts. This view is known as conceptualism. Recently, Kantians Robert Hanna and Lucy Allais, among others, have brought against this view the charge that it neglects the (...) possibility of the existence of essentially nonconceptual content that is not conceptualised or subject to conceptualisation. Their critique of McDowell amounts to nonconceptualism. However, both views, conceptualist and nonconceptualist, share the assumption that intuition is synthesised content in Kant’s sense. My interest is not in the validity of the philosophical positions of conceptualism or nonconceptualism per se. I am particularly interested in the extent to which the views that McDowell and Hanna and Allais respectively advance are true to Kant, or can validly be seen as Kantian positions. I argue that although McDowell is right that intuition is only epistemically relevant in conjunction with concepts, Hanna and Allais are right with regard to the existence of essentially nonconceptual content (intuitions) independently of the functions of the understanding, but that they are wrong with regard to non-conceptualised intuition being synthesised content in Kant’s sense. Kantian conceptualists (Bowman 2011; Griffith 2012; Gomes 2014) have responded to the recent nonconceptualist offensive, with reference to A89ff./B122ff. (§13)—which, confusingly, the nonconceptualists also cite as evidence for their contrary reading—by arguing that the nonconceptualist view conflicts with the central goal of the Transcendental Deduction, namely, to argue that all intuitions are subject to the categories. I contend that the conceptualist reading of A89ff./B122ff. is unfounded, but also that the nonconceptualists are wrong to believe that intuitions as such refer strictly to objects independently of the functions of the understanding, and that they are mistaken about the relation between figurative synthesis and intellectual synthesis. I argue that Kant is a conceptualist, albeit not in the sense that standard conceptualists assume. Perceptual knowledge is always judgemental, though without this resulting in the standard conceptualist claim that, necessarily, all intuitions or all perceptions per se stand under the categories (strong conceptualism). I endorse the nonconceptualist view that, for Kant, perception per se, i.e. any mere or ‘blind’ intuition of objects (i.e. objects as indeterminate appearances) short of perceptual knowledge, does not necessarily stand under the categories. Perception is not yet perceptual knowledge. In this context, I point out the common failure in the literature on the Transcendental Deduction, both of the conceptualist and nonconceptualist stripe, to take account of the modal nature of Kant’s argument for the relation between intuition and concept insofar as cognition should arise from it.

This essay presents a critique of what Robert Hanna has recently called the ‘sensibility first’ reading of Kant. I first spell out, in agreement with Hanna, why the contemporary debate among Kant scholars over conceptualism and non-conceptualism must be understood only from within the perspective of what I dub the ‘priority question’—that is, the question whether one or the other of our “two stems” of cognition may ground the objectivity and normativity of the other. I then spell out why the (...) priority question may be asked only from within the perspective of self-consciousness. Specifically, the central issue to be dealt with is how what Kant calls the original combination of understanding and sensibility is a synthesis internal to an act of self-consciousness. Only then can we ask what that original synthesis might tell us about the possibility of prioritizing one capacity over another in a story of cognition generally. Once we see the central issue more clearly, then I will look at the ‘sensibility first’ view in its most general form and propose that it should be criticized for its failure to account for Kant’s notion of an objective unity of self-consciousness.

In this paper, we compare Heidegger and Sellars’ respective responses to Kant’s Schematism section of the Transcendental Analytic, taking heed of how both philosophers motivate a criticism of representationalism in their respective renderings while also prodding their Kantian insights towards a holist conception of normativity. We begin with an overview and analysis of Heidegger and Sellars’ holism, comparing both thinkers’ systematic thought. We then turn to how both appraise Kant' Schematism section, first working through Heidegger’s analysis of Kant’s understanding and (...) imagination. We follow this up with Sellars’ naturalized Kantianism, taking particular interest in how Sellars emphasizes the basic foundational units, i.e., ‘this-suches’, grounding Kant’s theory of perception. We appraise both approaches, making the case that they offer a compatible productive misreading. (shrink)

O objetivo do artigo consiste em analisar, a partir dos parágrafos 34 a 38 da obra Kant e o problema da metafísica e segundo a exegese heideggeriana, o sentido e pertinência da inserção da problemática antropológica anteposta às três questões fundamentais expostas na Crítica da razão pura. Heidegger converte um rol exaustivo, delimitado pelas três perguntas, em um rol exemplificado, ao colocar a indagação da antropologia filosófica como pressuposto e consequência necessária das três interrogações kantianas. Heidegger recorre ao conceito de (...) finitude, para validar a importância e para fundamentar a primazia da questão antropológica sobre as demais: a interrogação “que é o homem” transforma-se na primeira que dispensa, a partir de si, as três restantes. Na finitude estão circunscritas as discussões sobre o tempo, a autoafecção pura, a imaginação e o tempo originário. É na finitude que estão os verdadeiros sinais ou ecos da antropologia filosófica kantiana. (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)

In this chapter I advance a moderately conceptualist interpretation of Kant’s account of the threefold synthesis in the A-Deduction. Often the first version of TD, the A-Deduction, is thought to be less conceptualist than the later B-version from 1787 (e.g. Heidegger 1991, 1995). Certainly, it seems that in the B-Deduction Kant puts more emphasis on the role of the understanding in determining the manifold of representations in intuition than he does in the A-Deduction. It also appears that in the A-Deduction (...) the seemingly pre-conceptual aspects of a priori synthesis, namely those of the synthesis of apprehension and the imagination, are more prominently featured than in the B-Deduction. And the fact that in the A-Deduction judgement does not appear to play any significant role reinforces the view that the A-Deduction is less strongly conceptualist. I believe that Kant is a conceptualist also in the A-Deduction (as much as in the B-Deduction) in the sense that all syntheses, which are expounded in the second section of the A-Deduction, must be seen as involving the categories or the understanding as the seat of the categories. However, despite some apparent strong modal claims regarding apperception in the A-Deduction, I argue that Kant is a moderate conceptualist in the sense that he allows for the real possibility that some representations are apprehended that are not subsumed or subsumable under the categories, or determined or determinable by the understanding as the seat of the categories. Not all representations must be synthesised and hence be conceptualised (by means of the categories), nor are all representations necessarily conceptualisable (by means of the categories). Often it is argued that the application of the categories must be seen as separate from or prior to conceptualisation (that is, employment of concepts in a judgement), so that the categories must be considered to apply to representations at least to the extent that the productive imagination or recognitive synthesis is involved, even if no empirical concepts are applied in an actual judgement. But it is difficult to see how categories can apply outside the context of an actual judgement in which ipso facto empirical concepts are employed, because, after all, categories are nothing but logical functions of judgement (e.g. B143). More in particular, I shall argue for the claims that (1) appearances to the contrary, all three levels of syntheses in the A-Deduction, including the synthesis of recognition, are interdependent and are not to be seen as operating singly or independently of each other, and hence of the categories; (2) ‘mere’ apprehension, or ‘mere’ intuition, is not dependent on the understanding and the application or possible application of the categories; and that (3) ‘mere’ apprehension does not even invoke a priori synthesis of apprehension and hence is as such fully lawless in terms of Kantian a priori laws. In this context, I also address Kant’s argument in the A-Deduction about the role of the imagination in the production of spatial objects and explain his apt use of the example of cinnabar to show that the kind of association that is at issue here concerns the possibility of knowledge, not the possibility of mere association, as is often assumed.

This paper analyses the features of Kant’s transcendental philosophy, which Kant himself described as transcendental idealism. On the one hand, Kant’s transcendentalism rests on the distinction between things in themselves and appearances. On the other hand, our ‘mode of cognition’ [Critique, B25] cognition is representative in that is based on representations — subjective and objective ones. A synthesis of the above considerations suggests that Kant’s transcendentalism rests on the conceptual triad “[objective] object — appearance — and [mental] representation “. Kant’s (...) transcendentalism is impossible without the ‘premise’ of appearance. The correct interpretation of Kant’s transcendental philosophy should keep the double difference of appearance both from thing–in–itself and representation. In this transcendental triad, the Kantian appearance has an intermediate status since it is located between objective things and subjective representations. However, the conceptual status of the appearance needs to be clarified, since Kant himself does not give a clear answer to this question, and at present there are several interpretations, differing primarily in the definition of the concept of the appearance. For me, appearance can be correlated with objective–objectual representation. It would be unwise to identify appearance with thing in itself, which was characteristic of pre–Kantian philosophy, or appearance with representation, which was the case in phenomenalist interpretations of transcendental idealism à la Berkley. The Kantian appearance, as emphasised in BXXVII of his Critique, is an appearance of an object, which — although implicitly — suggests a semantic relationship of reference. In this case, the appearance is not an object, but just ‘a designation of an object’ [Critique, B235]. Appearance is impossible without what appears in it. This paper puts forward a number of arguments in favour of the objectual status of Kant’s concept of appearance. (shrink)

Is Kant a conceptualist or a nonconceptualist? Very roughly, this amounts to the following question: Do intuitions depend on concepts in order to represent objects? Much recent Kant scholarship is devoted to answering this question, which is of interest not only for its connection to contemporary debates in philosophy of mind and perception, but also because the answer one provides has important implications for how one understands crucial features of Kant’s account of cognition. In this extended review essay, I examine (...) how the authors in this volume, most of whom adopt some version of nonconceptualism, approach the following three questions: (1) Is the unity of the pure intuition of space as an all-encompassing whole independent of the understanding, and if so, what follows with respect to the unity of empirical intuitions? (2) When Kant says that all objects of the senses stand under the categories, does this mean that the categories play a role in generating intuitions, or is there a way of understanding this claim that is compatible with nonconceptualism (according to which intuitions do not depend on concepts in order to be intuitions)? And finally, (3) Are intuitions representational or relational states and what implications does this have for how we understand the role of intuitions in establishing real possibility? (shrink)

Famously, Kant is a transcendental idealist. Yet he also endorses empirical realism, and even boasts that only the transcendental idealist can be an empirical realist. The difficulty of making sense of those commitments together leads many interpreters to begin by attributing to Kant some variant of conventional, subjective idealism. That in turn requires that Kant's empirical realism be at best a merely ersatz or quasi-realism. But that drains Kant's boast of its significance. For any idealist can be a realist if (...) the 'realism' in question is defined in terms of a prior commitment to idealism. Thus I argue, on the contrary, that we must begin the interpretation of Kant's Critical philosophy by taking his empirical realism to be a genuine, common-sense realism about empirical things. That approach yields a consistent, satisfying, and novel reading of the Critical enterprise, including transcendental idealism, as explaining how empirical realism is possible. Along the way I show, among other things, (1) how to make systematic sense of Kant's controversial theory of meaning, which is standardly either downplayed or regarded as grossly inconsistent with his other core commitments; (2) how to dispense with the centuries-old Neglected Alternative objection; and (3) how to account for the syntheticity of the moral law and its role in conferring experience-immanent meaning on the practical postulates (e.g., of the existence of God). (shrink)

I argue for a new delimitation of what Kant means by ‘cognition [Erkenntnis]’, on the basis of the intermediate, transitional place that Kant gives to cognition in the ‘progression [Stufenleiter]’ of our representations and our consciousness of them. I show how cognition differs from mental acts lying earlier on this progression—such as sensing, intuiting, and perceiving—and also how cognition differs from acts lying later on this progression—such as explaining, having insight, and comprehending. I also argue that cognition should not be (...) confused with ‘knowledge [Wissen]’, insofar as knowledge represents the culmination of a separate orthogonal progression of acts of ‘holding-true’. Along the way, I show how having in focus the specific progression from representation, to consciousness, to cognition (and beyond) allows us to better appreciate the architectonic significance of the progression of Kant’s analysis in the first Critique (and beyond), and also helps to illuminate the unity of Kant’s account of cognition itself across its variety of (empirical, mathematical, philosophical) forms.

In “Kant and Degrees of Responsibility,” Joe Saunders claims that “Degrees of responsibility are important for both our moral and legal practices” and argues that “transcendental idealism precludes Kant from vindicating these judgments [about degrees of responsibility]” ; thus, we have reasons to reject Kant’s transcendental idealism. In this paper, I show how Kant’s transcendental idealism can accommodate and provide a metaphysical account for degrees of responsibility. Whether this “vindicates” such judgments depends upon how much one expects a philosophical account (...) to do; I defend modesty there while admitting a reasonable desire for reflection on how we can and should make such judgments. Finally, I raise the question of just how important judgments of moral responsibility are. Rather than looking to metaphysics to figure out how to vindicate judgments about degrees of responsibility, I suggest we look to the practical purposes such judgments serve. (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.
