One of the central debates in contemporary Kant scholarship concerns whether Kant endorses a “conceptualist” account of the nature of sensory experience. Understanding the debate is crucial for getting a full grasp of Kant's theory of mind, cognition, perception, and epistemology. This paper situates the debate in the context of Kant's broader theory of cognition and surveys some of the major arguments for conceptualist and non-conceptualist interpretations of his critical philosophy.

In his argument for the possibility of knowledge of spatial objects, in the Transcendental Deduction of the B-version of the Critique of Pure Reason, Kant makes a crucial distinction between space as “form of intuition” and space as “formal intuition.” The traditional interpretation regards the distinction between the two notions as reflecting a distinction between indeterminate space and determinations of space by the understanding, respectively. By contrast, a recent influential reading has argued that the two notions can be fused into (...) one and that space as such is first generated by the understanding through an act of synthesis of the imagination. Against this reading, this article argues that a key characteristic of space as a form of intuition is its nonconceptual unity, which defines the properties of space and is as such necessarily independent of determination by the understanding through the transcendental synthesis of the imagination. The conceptual unity that the understanding prescribes to the manifold in intuition, by means of the categories, defines the formal intuition. Furthermore, this article argues that it is the sui generis, nonconceptual unity of space, when takenas a unity for the understanding by means of conceptual determination, that first enables geometric knowledge and knowledge of spatially located particulars.

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.

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.

I offer a new reconstruction of Hegel’s criticism of Kant’s idealism. Kant held that we impose categorial form on experience, while sensation provides its matter. Hegel argues that the matter we receive cannot guide our imposition of form on it. Contra recent interpretations, Hegel’s argument does not depend on a conceptualist account of perception or a view of the categories as empirically conditioned. His objection is that given Kant’s dualistic metaphysics, the categories cannot have material conditions for correct application. This (...) leads to subjectivism in the content of experience: the subject is given an implausibly strong role in determining what is the case. Hegel’s own absolute idealism solves this problem.

Kant's readers have disagreed about whether, according to his account of cognition, concepts, representations of the understanding, are involved in intuitions, representations of sensibility. But proponents of the affirmative 'conceptualist' answer and those of the negative 'non-conceptualist' answer have alike presupposed that such involvement should be construed in a particular way: i.e., as the involvement of particular concepts in particular exercises of sensibility. I argue, on the contrary, that it should not be: that though, for Kant, no concepts are applied (...) in exercises of sensibility, nonetheless the understanding, the faculty of concepts, is teleologically internal to sensibility and, therefore, to its exercises. That is, those exercises are per se directed towards the provision to the understanding of objects to which its fundamental concepts, the categories, are applicable, though no act of categorical application is internal to them. This conception of sensibility, available only in light of a careful distinction between capacities and acts, is demanded, I argue, by Kant's conception of a priori knowledge as elaborated in his Transcendental Deduction.

Kant is said to be the first to distinguish between consciousness of oneself as the subject of one’s experiences and consciousness of oneself as an object, which he calls transcendental and empirical apperception, respectively. Of these, it is empirical apperception that is meant to enable consciousness of any empirical features of oneself; what this amounts to, however, continues to puzzle interpreters. I argue that a key to understanding what empirical apperception consists in is Kant’s claim that each type of apperception (...) corresponds to a distinct type of unity of apperception—that is, a distinct way in which representations can be related for a subject. Whereas transcendental unity of apperception requires that representations be actively combined by the understanding, empirical unity of apperception obtains when representations are passively combined by the reproductive imagination. In light of this, I develop a novel account of Kant’s two types of apperception, according to which they correspond to a cognitive subject’s consciousness of two essential aspects of herself—namely, her spontaneity and receptivity.

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)

Does Kant hold that we can have intuitions independently of concepts? A striking passage from § 13 of the Critique of Pure Reason appears to say so explicitly. However, it also conjures up a scenario where the categories are inapplicable to objects of intuition, a scenario presumably shown impossible by the following Transcendental Deduction. The seemingly non-conceptualist claim concerning intuition have therefore been read, by conceptualist interpreters of Kant, as similarly counterpossible. I argue that the passage in question best supports (...) an underappreciated middle position where intuition requires a pre-conceptual use of the understanding. Such pre-conceptual use of the understanding faces both textual and systematic objections. I show that these objections can be rebutted. (shrink)

On one reading of Kant’s account of our original representations of space and time, they are, in part, products of the understanding or imagination. On another, they are brute, sensible givens, entirely independent of the understanding. In this article, while I agree with the latter interpretation, I argue for a version of it that does more justice to the insights of the former than others currently available. I claim that Kant’s Transcendental Deduction turns on the representations of space and time (...) as determinate, enduring particulars, whose unity is both given and a product of synthesis. (shrink)

In this paper, I propose a novel interpretation of the role of the understanding in generating the unity of space and time. On the account I propose, we must distinguish between the unity that belongs to determinate spaces and times – which is a result of category-guided synthesis and which is Kant’s primary focus in §26 of the B-Deduction, including the famous B160–1n – and the unity that belongs to space and time themselves as all-encompassing structures. Non-conceptualist readers of Kant (...) have argued that this latter unity cannot be the product of categorial synthesis. While they are correct that this unity is not the product of any particular act of category-guided synthesis, I argue that conceptualists are right to nevertheless attribute this unity to the understanding. I argue that it is a result of what we can think of as the ‘original’ synthesis of understanding and sensibility themselves – it is a synthesis, moreover, in which the whole is logically prior to the parts.

Are the pure intuitions of space and time, for Kant, dependent upon the understanding's activity? This paper defends the recently popular Self-Affection Thesis : namely, that the pure intuitions require an activity of self-affection—an influence of the understanding on the inner sense. Two systematic objections to this thesis have been raised: The Independence objection claims that SAT undermines the independence of sensibility; the Compatibility objection claims that certain features of space and time are incompatible with being the products of the (...) understanding's activity. I show that the resources to rebut these objections can be found in Kant's account of causal influence. (shrink)

The article proposes an interpretation of Kant’s notions of form of, and formal intuition of space to explain and justify the claim that representing space as object requires a synthesis. This involves identifying the transcendental conditions of the analytic unity of consciousness of this formal intuition and distinguishing between it and its content. On this reading which builds upon recent proposals, footnote B160–1n. involves no revision of the Transcendental Aesthetic: space is essentially characterized by non-conceptual features. The article also addresses (...) worries about the infinite magnitude and the unicity of space, by considering the characteristics and requirements of geometric constructions. (shrink)

Overview of the (non)conceptualism debate in Kant studies.

A comprehensive and practical study tool, introducing Kant's thought and key works and exploring his continuing influence.

In the Critique of Pure Reason Kant appears to make incompatible claims regarding the unitary natures of what he takes to be our a priori representations of space and time. I argue that these representations are unitary independently of all synthesis and explain how this avoids problems encountered by other positions regarding the Transcendental Deduction and its relation to the Transcendental Aesthetic in that work. Central is the claim that these representations (1) contain, when characterized as intuitions and considered as (...) prior to any affections of sensibility, only an infinitude of merely possible finite spatial and temporal representations, and (2) are representations that are merely transcendental grounds for the possibilities for receiving or generating finite representations in sensibility that are determined (immediately, in the case of reception) by means of syntheses that accord with the categories.

Prolegomena §38 is intended to elucidate the claim that the understanding legislates a priori laws to nature. Kant cites various laws of geometry as examples and discusses a derivation of the inverse-square law from such laws. I address 4 key interpretive questions about this cryptic text that have not yet received satisfying answers: How exactly are Kant's examples of laws supposed to elucidate the Legislation Thesis? What is Kant's view of the epistemic status of the inverse-square law and, relatedly, of (...) the legitimacy of the geometric derivation of that law? Whose account of laws, the understanding, and space is Kant critiquing in the passage? What positive account of the relationship between laws, the understanding, and space is Kant offering in the passage? My answer to depends crucially on my answers to –. As I interpret Kant, he holds that a wide range of a priori laws—including geometric laws, the inverse-square law, and the universal laws discussed in the Analytic of Principles—are ‘grounded’ in categorial syntheses rather than the intrinsic nature of the space given to us in pure intuition.

Kant’s published arguments for the non-spatiotemporality of things in themselves have not been well received. I argue that Kant has available to himself an argument for the non-spatiotemporality of things in themselves that is premised upon a disparity between the compositional structure of the intelligible world and the structure of space and time. I argue that Kant was unwaveringly committed to the premises of this argument throughout his career and that he was aware of their idealistic implications. I also argue (...) that this argument is consistent with Kant’s restrictive mature epistemology. If my argument is successful, then even if Kant’s published arguments for transcendental idealism fail, we need not regard his ambitious metaphysical project as a failure. (shrink)
