Early twentieth-century philosophers of perception presented their naïve realist views of perceptual experience in anti-Kantian terms. For they took naïve realism about perceptual experience to be incompatible with Kant’s claims about the way the understanding is necessarily involved in perceptual consciousness. This essay seeks to situate a naïve realist account of visual experience within a recognisably Kantian framework by arguing that a naïve realist account of visual experience is compatible with the claim that the understanding is necessarily involved in the (...) perceptual experience of those rational beings with discursive intellects. The resultant view is middle way between recent conceptualist and non-conceptualist interpretations of Kant, holding that the understanding is necessarily involved in the kind of perceptual consciousness that we, as rational beings, enjoy whilst allowing that the relations of apprehension which constitute perceptual consciousness are independent of acts of the understanding.

This book offers a radically new account of the development and structure of the central arguments of Kant's Critique of Pure Reason: the defense of the objective validity of such categories as substance, causation, and independent existence. Paul Guyer makes far more extensive use than any other commentator of historical materials from the years leading up to the publication of the Critique and surrounding its revision, and he shows that the work which has come down to us is the result (...) of some striking and only partially resolved theoretical tensions. Kant had originally intended to demonstrate the validity of the categories by exploiting what he called 'analogies of appearance' between the structure of self-knowledge and our knowledge of objects. The idea of a separate 'transcendental deduction', independent from the analysis of the necessary conditions of empirical judgements, arose only shortly before publication of the Critique in 1781, and distorted much of Kant's original inspiration. Part of what led Kant to present this deduction separately was his invention of a new pattern of argument - very different from the 'transcendental arguments' attributed by recent interpreters to Kant - depending on initial claims to necessary truth.

This chapter outlines Kant’s account of empirical concept formation and discusses two objections that have been advanced against it. Kant holds that we form empirical concepts, such as colour concepts, by comparing sensory representations of individuals, identifying shared features, and abstracting from the differences between them. According to the first objection, we cannot acquire colour concepts in this way because there is no feature that all and only the instances of a given colour share and the boundary between colours is (...) conventional. According to the second objection, assuming that all instances of a given colour share certain features, we can identify them only if we already possess a concept of that colour. None of the two objections is convincing as it stands. Kant can offer replies to both objections that are consistent with his views and with empirical evidence concerning the perception and representation of colours. (shrink)

What do we see? We are visually conscious of colors and shapes, but are we also visually conscious of complex properties such as being John Malkovich? In this book, Susanna Siegel develops a framework for understanding the contents of visual experience, and argues that these contents involve all sorts of complex properties. Siegel starts by analyzing the notion of the contents of experience, and by arguing that theorists of all stripes should accept that experiences have contents. She then introduces a (...) method for discovering the contents of experience: the method of phenomenal contrast. This method relies only minimally on introspection, and allows rigorous support for claims about experience. She then applies the method to make the case that we are conscious of many kinds of properties, of all sorts of causal properties, and of many other complex properties. She goes on to use the method to help analyze difficult questions about our consciousness of objects and their role in the contents of experience, and to reconceptualize the distinction between perception and sensation. Siegel's results are important for many areas of philosophy, including the philosophy of mind, epistemology, and the philosophy of science. They are also important for the psychology and cognitive neuroscience of vision. (shrink)

it is sometimes said that one of Kant’s decisive advances over his predecessors was to have anticipated Frege’s functional theory of concepts, along with its corollary that a concept has significance only in the context of the whole proposition.1 Kant is said to break with a tradition that held that there is a self-standing species of concept-use—called apprehensio simplex, or the conceiving of an idea—in which one represents objects by having a concept before one’s mind, independently of connecting it with (...) other concepts in judgment.2 Since Kant’s use of ‘judgment’ covers what Frege calls judging as well as what he calls grasping a thought, the idea is that according to Kant the only way for a thinker to use a..

Against a view currently popular in the literature, it is argued that Kant was not a niıve realist about perceptual experience. Naive realism entails that perceptual experience is object-dependent in a very strong sense. In the first half of the paper, I explain what this claim amounts to and I undermine the evidence that has been marshalled in support of attributing it to Kant. In the second half of the paper, I explore in some detail Kant’s account of hallucination and (...) argue that no such account is available to someone who thinks that veridical perceptual experience is object-dependent in the naive realist sense. Kant’s theory provides for a remarkably sophisticated, bottom-up explanation of the phenomenal character of hallucinatory episodes and is crucial for gaining a proper understanding of his model of the mind and its place in nature.

I give an argument against nonconceptualist readings of Kants claim that intuitions and concepts constitute two distinct kinds of representation than is assumed by proponents of nonconceptualist readings. I present such an interpretation and outline the alternative reading of the Deduction that results.

Kant famously declares that “although all our cognition commences with experience, … it does not on that account all arise from experience”. This marks Kant’s disagreement with empiricism, and his contention that human knowledge and experience require both sensation and the use of certain a priori concepts, the Categories. However, this is only the surface of Kant’s much deeper, though neglected view about the nature of reason and judgment. Kant holds that even our a priori concepts are acquired, not from (...) sensation, but “originally,” because our mind has a fundamental capacity to judge that, upon sensory stimulation, generates the Categories through its basic logical functions of judgment. This “epigenesis” of reason and our fundamental capacity to judge that drives it is the topic of Longuenesse’s fascinating book, and the source of her title. (shrink)

Ob die Kategorien schon bei der Wahrnehmung eine Rolle spielen, wird von Kant-Interpreten unterschiedlich gesehen. Peter Rohs etwa argumentiert für eine Unabhängigkeit und Selbständigkeit der Wahrnehmung gegenüber dem Verstand. Die intuitive Synthesis der Einbildungskraft müsse auf eigenen Füßen stehen können und Bilder und „singuläre Sinne“ der Anwendung der Begriffe vorausgehen. McDowell hingegen spricht sich gegen eine solche Selbständigkeit der Wahrnehmung aus. Setzte man sie voraus, käme der Verstand immer zu spät . Die Argumente beider Seiten sollen am Text Kants untersucht (...) werden . Es liegt hier ein echtes Sachproblem vor. Die gegenwärtige, hauptsächlich amerikanische Diskussion um eine etwaige Notwendigkeit kognitiver Funktionen bei der Wahrnehmung stößt auf ganz ähnliche Probleme wie wir sie schon bei Kant finden, nur daß man sich dieser Ähnlichkeit außerhalb von Kantkreisen oft nicht bewußt zu sein scheint.

stefanie grüne takes issue with our claim that for an object to be given, this object must exist. On her view, givenness, according to Kant, does not require the existence of the object, but only its real possibility. She develops her critique in three steps. First, she argues that the reason why Kant requires objects to be given in intuition is that otherwise our concepts would not have ‘objective reality’ and would thus not constitute cognitions. But since the objective reality (...) of a concept corresponds to the real possibility of its object, this is supposed to show that givenness does not require existence. Second, she challenges our remarks on mathematical cognition, claiming that in the... (shrink)

The book addresses the debate on whether the representational content of perceptual experience is conceptual or non-conceptual, by bringing out the points of comparison between Kant s conception of intuition and contemporary accounts of non-conceptual content. It is argued that intuition provides the most basic form of intentionality pre-conceptual reference to objects, which underlies the acts of conceptualization and judgment.".

I present an argument for an interpretation ofKant's views on the nature of the ‘content [Inhalt]’ of ‘cognition [Erkenntnis]’. In contrast to one of the longest standing interpretations ofKant's views on cognitive content, which ascribes toKant a straightforwardly psychologistic understanding of content, and in contrast as well to the more recently influential reading ofKant put forward byMcDowell and others, according to whichKant embraces a version ofRussellianism, I argue thatKant's views on this topic are of a much moreFregean bent than has (...) traditionally been admitted or appreciated. I conclude by providing a sketch of how a better grasp ofKant's views on cognitive content in general can help bring into sharper relief what is, and what is not, at stake in the recent debates over whether Kant accepts a particular kind of cognitive content—namely, non‐conceptual content.

This paper examines some of the central arguments of John McDowell's Mind and World, particularly his treatment of the Kantian themes of the spontaneity of thought and of the nature of self-consciousness. It is argued that in so far as McDowell departs from Kant, his position becomes less plausible in three respects. First, the space of reason is identified with the space of responsible and critical freedom in a way that runs together issues about synthesis below the level of concepts (...) and at the level of complete judgements. This leads to the unwarranted exclusion of animal minds from the space of reasons. Second, McDowell draws no essential distinction between apperception and inner sense, a distinction which is important to a defensible Kantian view and to the very idea of a sui generis transcendental knowledge of the mind that is consistent with Kant's critical principles. McDowell does not take into account some of Kant's developed arguments about the inherently reflective nature of consciousness which is interpreted as an adverbial theory of the nature of conscious experience, a mode of being in a mental state . Third, McDowell endorses a standard treatment of Kant's approach to the mind in which a merely formal account of mind needs to be anchored outside consciousness on the physical body. The arguments for this conclusion, both in Mind and World and in related work by Bermudez and Hurley, is shown to be very inconclusive as a criticism of Kant. The capacity to self-ascribe thoughts that are already conscious shows, but does not say, a truth about the unity of our conscious experience that does not require further anchoring on a physical body; at that stage of the Critique Kant is describing conditions for conscious experience in general, not the conscious experience of spatio-temporally located makers of judgements. The alleged lacuna in Kant's arguments is no lacuna at all. (shrink)

Recognitional concepts have the following characteristic property: thinkers are disposed to apply them to objects merely on the basis of undergoing certain perceptual experiences. I argue that a prominent strategy for defending the existence of constitutive connections among concepts, which appeals to thinkers’ semantic-cum-conceptual intuitions, cannot be used to defend the existence of recognitional concepts. I then outline and defend an alternative argument for the existence of recognitional concepts, which appeals to certain psychological laws.

Nonhuman animals seem to make inferences and have mental representations. Brandom articulates a Kantian (and Hegelian) account of representation that seems to make nonhuman mental content impossible: animals are merely sentient, not sapient. His position is problematic because it makes it impossible to understand how our cognitive capacities evolved. This essay discusses experimental and ethological work on transitive inference. It argues that to fit such evidence within the Kantian framework, there must be degrees of normativity. This invites us to understand (...) the distinction between sapience and sentience as endpoints of a continuum, not as a dichotomy. (shrink)

In the Critique of Pure Reason, Kant refers often and with no apparent hesitation or sense of ambiguity to the mind. He does so not only in his justly famous destruction of rationalist proofs of immaterialism, but throughout his own, positive, ‘transcendental’ account in the Transcendental Aesthetic and Transcendental Analytic. In the first edition of the Critique, he even proposed what he adventurously called a ‘transcendental psychology’ and, although this strange discipline seemed to disappear in the second edition, he left (...) in that edition all his frequent references to forms ‘lying in the mind,’ and to the mind, or the self, or the subject of experience, or the ego, doing this or that. Curiously, though, despite an extensive secondary literature, there is in that literature relatively little discussion of what these expressions, in a proper, strictly Kantian sense, are supposed to refer to. There are two imaginative, extremely suggestive articles by Sellars, some hints at connections with eighteenth century psychology offered by Weldon, a tenebrous book by Heidemann, and some recent attention to the general issue of ‘Kant's theory of mind’ by Ameriks and Kitcher.

In this paper, I propose a new nonconceptual reading of the B-Deduction. As Hanna correctly remarks :399–415, 2011: 405), the word “cognition” has in both editions of the first Critique a wide sense, meaning nonconceptual cognition, and a narrow meaning, in Kant’s own words “an objective perception”. To be sure, Kant assumes the first meaning to account for why the Deduction is unavoidable. And if we take this meaning as a premise of the B-Deduction, then there is a gap in (...) the argument since the categories are certainly not conditions for non-conceptual cognition. Still, I believe it is not this wide meaning but rather the narrow one that figures in any premise of the B-Deduction. Thus, in the reading that I am proposing, categories are not conditions for representing something, or even conditions for representing something objectively. Instead, they are conditions for the recognition that what we represent through the senses exists mind-independently. In the first step of the B-Deduction, this cognition in the narrow sense takes the form of the propositional thinking that the nonconceptually represented object of the sensible intuition exists objectively. In contrast, in the second step of the B-Deduction, this cognition in the narrow sense takes the form of the apprehension of what our human senses represent nonconceptually as existing objectively.

In order to perceive something, one must have a sense experience which it causes and which has a content that fits it appropriately. But veridical hallucinations show that more is required, viz., that the experience must also be caused by the object of perception in the right sort of way. The best account of what this amounts to is that the object causes the experience by means of a “reliable mechanism,” i.e., a causal mechanism which is generally apt to connect (...) objects to experiences with contents that fit those objects. The paper advances and defends a careful account of this position and its application to the distinction between state of affairs perception, event perception and thing perception. (shrink)

Judgement, perception, and other mental states and events have a minimal objectivity in this sense: making the judgement or being in the mental state does not in general thereby make the judgement correct or make the perception veridical. I offer an explanation of this minimal objectivity by developing a form of constitutive transcendental argument. The argument appeals to the proper individuation of the content of judgements and perceptions. In the case of the conceptual content of judgements, concepts are individuated by (...) their fundamental reference rules. Properly developed, this resource can be used against various forms of idealism, and to defend a conception of transcendental arguments that presupposes neither verificationism nor transcendental idealism. The article contrasts its approach with other recent transcendental treatments. It also addresses the relation between its argument and Principles of Significance. I close with a discussion of the right way of handling the extreme generality necessarily involved in transcendental reasoning. (shrink)

In the Transcendental Aesthetic, Kant famously characterizes space as a unity, understood as an essentially singular whole. He further develops his account of the unity of space in the B-Deduction, where he relates the unity of space to the original synthetic unity of apperception, and draws an infamous distinction between form of intuition and formal intuition. Kant ’s cryptic remarks in this part of the Critique have given rise to two widespread and diametrically opposed readings, which I call the Synthesis (...) and Brute Given Readings. I argue for an entirely new reading, which I call the Part-Whole Reading, in part by considering the development of Kant ’s views on the unity of space from his earliest works up through crucial reflections written during the silent decade.

My aim in this paper is to offer a systematic analysis of a feature of Kant’s theory of perception that tends to be overlooked, viz., his account of how the imagination forms images in perception. Although Kant emphasizes the centrality of this feature of perception, indeed, calling it a ‘necessary ingredient’ of perception, commentators have instead focused primarily on his account of sensibility and intuitions on the one hand, and understanding and concepts on the other. However, I show that careful (...) attention to what he says about the nature of images, their connection to the imagination, and their role in perception in his Metaphysics Lectures, as well as in the Deduction and Schematism chapters of the first Critique reveals that Kant is working with a richer, more nuanced framework for perception than is often attributed to him. I contend that it is only once we have a revised framework for Kant’s theory of perception in place that we will be able to make further headway in debates, e.g., about whether or not he is a conceptualist about perception.

It has long been debated whether objects are ‘sortally’ individuated. This paper begins by clarifying some of the key terms in play—in particular, ‘sortal’, ‘individuation’, and ‘object’. The term ‘individuation’ is taken to have both a cognitive and a metaphysical sense, in the former denoting the singling out of an object in thought and in the latter a determination relation between entities. ‘Sortalism’ is defined as the doctrine that only as falling under some specific sortal concept can an object be (...) successfully singled out in thought. It is argued that such a view is too strong, but that a weaker one, ‘categorialism’, can be defended, this implying that a thinker cannot successfully single out an object in thought without having at least an implicit grasp of the criterion of identity that the object satisfies.

Problems and Postulates: Kant on Reason and Understanding ALISON LAYWINE THE PURPOSE OF THIS PAPER is to think anew Kant's conception of reason and understanding, the relation between these two faculties and the principles that govern them. I am chiefly interested in the contributions of reason and under- standing to the advancement of knowledge. Hence the focus of my paper, so far as reason itself is concerned, is the theoretical rather than the practical employment of this faculty. On the other (...) hand, I think it is useful and fair to say, on Kant's account, that theoretical reason is itself practical -- at least to the extent that we regard scientific enquiry as some kind of activity, namely a research activity, involving practices such as proof and experimentation, under- taken for the sake of a certain end, namely, the acquisition of knowledge. One of Kant's concerns in the Critique of Pure Reason is to explain how this activity can be profitably pursued. To meet this concern, Kant must explain first of all how we set research goals for scientific enquiry. For without any such goals, Susan Neiman's book, The Unity of Reason , was the original stimulation for this paper. . I am more indebted to Susan.. (shrink)

There is an emerging consensus among interpreters that in his Critical writings Kant ascribes unconscious representations to the mind. The nature and extent of this ascription over the course of Kant’s philosophical development is however not well understood. I argue that from his earliest published writings Kant consistently ascribes unconscious representations to the mind; that some of these representations are unconscious in the strong sense that they are not available to introspection; and that Kant extends his commitment to unconscious representations (...) by ascribing to the mind unconscious acts of judging and reasoning.

Mental representations—like many other things—seem to have parts. However, it isn’t clear how to properly understand the idea of a part of a representation. In this paper I shed new light on how representations can have a mereology. In particular, it has been recognized that there is a mereological element to Kant’s distinction between two kinds of representations: intuitions and concepts. A concept depends upon its parts, whereas an intuition is prior to its parts. The paper thus focuses on an (...) exploration of how to make sense of the parts and wholes of intuitions and concepts.

The Duisburg Nachlaß is a bundle of Kant’s handwritten notes. These notes almost certainly go back to some time in 1775. Though very obscure, they replay issues in Kant’s early metaphysics just as clearly as they anticipate issues in the Critique of Pure Reason. This makes them an important way-station in Kant’s philosophical development—all the more important, because he published nothing in the 1770s and left no other extended writings in his own hand. A proper understanding of the Duisburg Nachlaß (...) might therefore explain some of Kant’s later ideas: their origins in his earlier thinking and their philosophical motivations. The purpose of this paper is to lay the groundwork for such an explanation—at least a partial one. I shall argue that Kant’s efforts in the Duisburg Nachlaß to correct certain difficulties in the Inaugural Dissertation of 1770 anticipate and naturally lead to the crucial claim in the Critique of Pure Reason that the understanding legislates laws to nature.

Two lines of argument with which kant defends the distinction between thought and intuition are examined. It is argued that attempts to establish thought and intuition as separate faculties on the basis of the immediacy and singularity of intuitions and the mediacy and generality of concepts fail. Kant's second way of making out the distinction is a transcendental account of the possibility of an intellect like ours. He argues that it is a fundamental characteristic of the human intellect that it (...) is not intuitive and that we can be brought into relation with objects only through an intuitive faculty distinct from the faculty of conceptual representation. This line of argument is reconstructed from kant's correspondence and the "critique of judgment", And it is argued that it represents "a" plausible kantian response to criticisms of his distinction.

In a famous passage (A68/B93), Kant writes that “the understanding can make no other use of […] concepts than that of judging by means of them.” Kant's thought is often called the thesis of the priority of judgments over concepts. We find a similar sounding priority thesis in Frege: “it is one of the most important differences between my mode of interpretation and the Boolean mode […] that I do not proceed from concepts, but from judgments.” Many interpreters have thought (...) that Frege's priority principle is close to (or at least derivable from) Kant's. I argue that it is not. Nevertheless, there was a gradual historical development that began with Kant's priority thesis and culminated in Frege's new logic. (shrink)

In this essay I argue that a broadly Kantian strategy for demonstrating and explaining the existence, semantic structure, and psychological function of essentially non-conceptual content can also provide an intelligible and defensible bottom-up theory of the foundations of rationality in minded animals. Otherwise put, if I am correct, then essentially non-conceptual content constitutes the semantic and psychological substructure, or matrix, out of which the categorically normative a priori superstructure of epistemic rationality and practical rationality - Sellars's "logical space of reasons" (...) - grows.

I argue that Kant's claim in the “Transcendental Aesthetic” of the Critique of Pure Reason that space and time are immediately given in intuition as infinite magnitudes is undercut by his general theory of mathematical knowledge. On this general theory, pure intuition does not give objects of any determinate magnitude at all, but only forms of possible objects. Specifically, what pure intuition itself yields is the recognition that any determinate space or time is part of a larger one, but it (...) requires an inference of reason to go from that to the claim that space and time are infinite. I further argue that this result is consistent with Kant's claim in the second-edition “Transcendental Deduction” that the unity of space and time are the products of synthesis, but also means that the unity of space and time as objects cannot be used a premise in the Deduction but can only be regarded as a conclusion of the deduction and the following “System of Principles.”.

in kant’s account of cognition, Eric Watkins and Marcus Willaschek distinguish between a ‘broad’ and ‘narrow’ sense of Kant’s use of the term ‘cognition.’ Every “conscious representation that represents an object” counts as a cognition, taken in the broad sense.1 Every “conscious representation of a given object and of its general features” counts as a cognition in the narrow sense.2 In the case of finite beings, they argue, cognition in the narrow sense must fulfill two conditions: First, the object must (...) be given, since cognition must actually latch onto an object, and intuition satisfies that condition insofar as it immediately relates to the object represented in the intuition....

The view that the content of experience is conceptual is often felt to conflict with the empiricist intuition that experience precedes thought, rather than vice versa. This concern is explicitly articulated by Ayers as an objection both to McDowell and Davidson, and to the conceptualist view more generally. The paper aims to defuse the objection in its general form by presenting a version of conceptualism which is compatible with empiricism. It proposes an account of observational concepts on which possession of (...) such a concept involves more than the ability for perceptual discrimination, but less than the capacity to employ the concept in inferences: it consists in the capacity to perceptually discriminate objects with the awareness that one is discriminating as one ought. This understanding of concept-possession allows us make sense of experiences' having conceptual content without supposing that the subject must grasp the relevant concepts prior to having those experiences.
