Kant: Concepts

I argue that, for Kant, there is a point at which the notions of self-consciousness and self-limitation become one. I proceed by spelling out a logical progression of forms of self-consciousness in Kant’s philosophy, where at each stage we locate the limits of the capacity in question and ask what it takes to know those limits. After briefly sketching a notion of self-consciousness available even to the animal, we look at whether there could be a notion of self-consciousness available to (...) the capacity of human sensibility. At this stage I argue that Kant and Heidegger (or Heidegger’s Kant) share a conception of what it is to be self-limiting through self-consciousness. I then critically examine this conception, and, specifically, the way in which it fails to account for the most essential form of self-limitation in Kant’s critical philosophy—namely, the form of self-limitation which rejects spatial and temporal articulation. The conclusion we reach is that Kant’s theory of transcendental self-consciousness is a theory of the activity of thinking as determining itself (including its limits) non-spatially and non-temporally.

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 his lecture on logic, Kant puts forth his most detailed account of concept formation. Here Kant maintains that concepts are the result of a three-step process: comparison, reflection, and abstraction. Though most commentators acknowledge that this particular passage leads to a number of interpretive difficulties, it is almost unanimously accepted that: (1) concepts are composed of features which are shared by a multiplicity of objects and (2) that it is in virtue of these features that concepts apply to a (...) “plurality of objects”. I reject both of these claims. In what follows I will argue that the dilemma is the result of an illicit interpretive slide between the discussion of the form and content of concepts. The aim of this paper is to propose an alternative reading of Kant’s account of logical form—universality. I will argue that in the relevant passages, Kant’s account of concept formation is concerned not with a comparison, reflection, and abstraction of sensible features or marks but rather with the apprehension of the manifold (or the mode of bringing the manifold to the unity of consciousness).

In this essay, I specify types of representational content that can be attributed to Kant’s account of representation. The more specific aim is to examine which of these types of content can be regarded as possible without the application of concepts. In order to answer the question, I proceed as follows. First, I show how intuition (in Kant’s sense) can be seen as providing indexical content independently of empirical concepts. Second, I show in what sense the generation of spatial content (...) can be regarded as non-categorial. A key distinction is that a perceptual examination of an object can be understood as thoroughly sensible and particular, whereas a conceptual determination always grasps the object via its generalisable features. Third, I propose that the faculties of sensibility and understanding are not only separable in principle, but that their contributions remain in a certain sense separate in actual cognition as well. This is to say that a conceptual determination of an object does not entail that the object ceases to be non-conceptually available to the perceiver, which further suggests the autonomy of sensibility and its perceptual content. Finally, I raise difficulties in attributing non-conceptual representational content to Kant’s judgment-centered stance on representation and experience, only to emphasise how these difficulties easily lead to a misappreciation of Kant’s fundamental distinction between sensibility and understanding and their unique cognitive contributions.

: This paper examines two features of Kant’s 1768 critique of Leibniz’ conception of space. Firstly, Leibniz’ proposed geometrical calculus called ‘analysis situs’; secondly, Leibniz’ relational conception of space. The main thesis of the paper is that Kant’s arguments are more powerful than generally recognized. With regard to the analysis situs, I will show that Kant was quite well informed about this proposed science and that his arguments severely undermine Leibniz’ claims to what it could perform. With regard to the (...) relational theory of space, Kant’s argument would require Leibniz to present a complex story about the relation between God’s act of creation and our spatial experience to defend his relational view, rather than using the simple principle of sufficient reason.

No Abstract In his graduate-seminar lectures on Kant—published as Kant and Pre-Kantian Themes (Sellars, 2002)—Wilfrid Sellars argues that because Hume cannot distinguish between a vivacious idea and an idea of something vivacious he cannot account for the human ability to represent temporally complex states of affairs. The first section of this paper aims to show that this argument is not properly aimed at the historical Hume who can, on a proper reading, distinguish these kinds of representations. This is not, however, (...) Sellars’ only argument for this conclusion. The next section of this paper continues with a discussion of an argument that Sellars presents on Kant’s behalf in Science and Metaphysics, and its key Kantian premise that, contra Hume, only conceptual representations can represent any complex states of affairs as such. The conclusion of this discussion is that Sellars does indeed present compelling reasons for rejecting a Humean account, reasons centered on the ambiguity of the associative structure of mental representation (which Sellars subsequently replaces with inferential structure). The paper concludes with an examination of the sense in which non-conceptual representations—such as those that Hume considers—represent and the role that these play in conceptual representation for both Sellars and Kant.

It is quite standard, even banal, to describe Kant's project in the Critique of Pure Reason [KrV] as a critical reconciliation of rationalism and empiricism, most directly expressed in Kant's claim that intuitions and concepts are two distinct, yet equally necessary, and necessarily interdependent sources of cognition. Similarly, though Kant rejects both the rationalist foundation of morality in the concept of perfection and that of the empiricists in feeling or in the moral sense, one might broadly characterize Kant's moral philosophy (...) as an attempt to reconcile the apriori universality and necessity of rationalist ethics with empiricist or sentimentalist strictures concerning the distinction between the ‘ought’ and the ‘is’, between third personal knowledge of the good and first personal motivation.

In the Critique of Pure Reason, Kant argues for two principles that concern magnitudes. The first is the principle that ‘All intuitions are extensive magnitudes,’ which appears in the Axioms of Intuition ; the second is the principle that ‘In all appearances the real, which is an object of sensation, has an intensive magnitude, that is, a degree,’ which appears in the Anticipations of Perception. A circle drawn in geometry and the space occupied by an object such as a book (...) are paradigm examples of extensive magnitudes, while the intensity of a light is a paradigm example of an intensive magnitude. These principles justify and explain the possibility of applying mathematics to objects of experience. The Axioms principle also explains the possibility of any mathematical cognition at all. These principles are central to Kant’s theory of human cognition. Nevertheless, I believe that Kant’s notions of magnitude, the principles in which they appear, and the arguments for them have been misunderstood. Kant defines the concept of magnitude in the Axioms of Intuition, which also contains the most important claims concerning magnitudes. The focus of this paper will therefore be on the Axioms. It will reconstruct Kant’s arguments and analyze his concepts in order to reveal his theory of magnitudes and help explain his theory of human cognition. It will also argue that in Kant’s view, mathematical cognition crucially depends on the properties of magnitudes, and that intuition plays an important role in mathematical cognition by allowing us to represent those properties. These results reveal a role for intuition in Kant’s philosophy of mathematics that has passed unnoticed, and they open a new line of investigation into Kant’s philosophy of mathematics. (shrink)

One of the central and most distinctive theses of Kant’s philosophy of mathematics is that mathematical knowledge is synthetic. In this context, synthetic judgments are defined in opposition to analytic ones, whose predicate concept is “contained in” the subject. Kant’s thesis has often been attacked as indefensible, but just as frequently critics have complained that the thesis itself, and even the analytic/synthetic distinction on which it rests, are simply unintelligible. Thus, even prior to questions of its correctness, the Kantian doctrine (...) has been rejected as unclear, based on general skepticism that there is a real distinction of “containment”—or indeed any tolerably clear distinction at all—between analytic and synthetic judgments.

Encore que l’ouvrage de Monique Castillo cherche à cerner l’interrogation philosophique kantienne dans son ensemble, il ne constitue pas pour autant une introduction à Kant au sens classique du terme. Ce livre exige en effet une certaine familiarité avec l’œuvre dans la mesure où le lecteur est convié à un parcours inédit et spéculatif visant à montrer l’unité profonde et la cohérence interne du kantisme. Ne se contentant pas uniquement de mettre en contexte les différents éléments du système, l’auteure se (...) livre à un véritable travail de reconstruction en mettant au jour les nombreux liens qui en tissent la trame.

Kant's philosophy of geometry rests upon his doctrine of the "schematism" which I argue is formally identical to the ability to grass the middle term of an Aristotelian syllogism. The doctrine fails to avoid obscurities which were already present in Plato, Aristotle, and Hume.

This paper argues that kant's general epistemology incorporates a theory of algebra which entails a less constricted view of kant's philosophy of mathematics than is sometimes given. To extract a plausible theory of algebra from the "critique of pure reason", It is necessary to link kant's doctrine of mathematical construction to the idea of the "schematism". Mathematical construction can be understood to accommodate algebraic symbolism as well as the more familiar spatial configurations of geometry.

3. One of the most striking features of Kant’s epistemology is his insistence on the need for a sharp distinction between sensibility and understanding. “Our knowledge,” he tells us, “springs from two fundamental sources of mind; the first is the capacity of receiving representations, the second is the power of knowing an object through these representations. Intuitions and concepts constitute, therefore, the elements of all our knowledge….” In spite of this radical difference in role, both sensibility and understanding are construed (...) as, in a broad and ill-defined sense, faculties of representation. It is this, perhaps, which leads him to suggest that they may “spring from a common, but to us unknown, root.”. (shrink)

At A71/B96–7 Kant explains that singular judgements are ‘special’ because they stand to the general ones as Einheit to Unendlichkeit. The reference to Einheit brings to mind the category of unity and hence raises a spectre of circularity in Kant’s explanation. I aim to remove this spectre by interpreting the Einheit-Unendlichkeit contrast in light of the logical distinctions among universal, particular and singular judgments shared by Kant and his logician predecessors. This interpretation has a further implication for resolving a controversy (...) over the correlation between the logical moments of quantity (universal, particular, singular) and the categorial ones (unity, plurality, totality).

According to Hume, determinations of necessary causal connection are without empirical warrant, but, as he maintains, the concept of causality qua necessary connection is indispensable to human beings, having survival value for them, a claim which points to the biological significance of this concept. In contrast to Hume, Kant argues that the causal principle qua necessary connection belongs to the a priori conceptual framework by which rational beings constitute their experience and render the world intelligible. In “Kant’s Doctrine of the (...) A Priori in Light of Contemporary Biology” evolutionary epistemologist Konrad Lorenz sought to adapt Kant’s philosophy to contemporary biology by arguing that the a priori concepts of the understanding can be interpreted as comprising a biologically inherited framework, yet one that is provisional and in flux. Such an evolutionary interpretation of both Hume and Kant’s perspectives of the lacuna concerning causality brings the ideas of these thinkers closer together. Kant himself used suggestive analogies between the major epistemological positions concerning the origin of the a priori concepts of the understanding and the major biological theories of his time concerning the generation and development of organisms. Nevertheless, Kant would probably be reluctant to embrace such an evolutionarily-oriented conception of the categories, given his descriptions of them as self-thought, a priori first principles having a purely intellectual origin, belonging as a very condition for the possibility of the experience of rational beings in general, and as neither the product of a process of development, nor subject to one. This paper shows how Hegel’s emphasis on the dialectical progression of the logical Concept can help to ground Lorenz’s evolutionary neo-Kantianism. Toward the end of the paper, I discuss the evolutionary relevance of skepticism and critical thinking in this process via the notion of “Intellectual Selection.”. (shrink)

In Kant, Science, and Human Nature, Robert Hanna argues against a version of scientific realism founded on the Kripke/Putnam theory of reference, and defends a Kant-inspired manifest realism in its place. I reject Kriple/Putnam for different reasons than Hanna does, and argue that what should replace it is not manifest realism, but Kant‘s own scientific realism, which rests on a radically different theory of reference. Kant holds that we picture manifest objects by uniting manifolds of sensation using concepts-qua-inferential-rules. When these (...) rules are demonstrated to be invalid, we replace the picture of the macroscopic world with a picture of the microscopic entities of theoretical science that unites the very same manifolds using different rules of inference. Thus, we refer to "unobservable" theoretical entities in the same way that we do manifest ones: by specifying both their determinate location in space and time and the concepts by which they are understood. (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)

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.

A critical discussion of Waxman's recent book, Kant's Anatomy of the Intelligent Mind.

The Role of the Notion of Truth in the Project of Kant’s Critical Philosophy [English] The discussion about Kant’s theory of truth usually revolves around his ascription to some version of the coherence or correspondence theory of truth, and the matching criteria of truth. These discussions often deliberate which theory of truth is most appropriate given the critical principles. Instead, this paper aims to exhibit, through the evolution of Kant’s notion of truth in his precritical years and through the project (...) of a transcendental logic, the intrinsic relation between the notion of truth and the very principles of critical philosophy; and to raise again the questions about the definition and the criteria of truth, but in the framework of the question of the possibility of truth. [Español] La discusión en torno a la teoría kantiana de la verdad suele girar alrededor de las preguntas —íntimamente relacionadas entre sí— por la adscripción de Kant a una versión coherentista o correspondentista de la verdad y por los correspondientes criterios de verdad. Estas discusiones suelen ponderar qué teoría de la verdad resulta más adecuada dados ya los principios críticos. En contraste con esto, este trabajo pretende mostrar, a través de la evolución de la noción de verdad del Kant precrítico y del proyecto de una lógica trascendental, la vinculación intrínseca de la noción de verdad con los principios mismos de la filosofía crítica, y replantear las preguntas por la definición y el criterio de verdad en el marco de la pregunta por la posibilidad de la verdad.

Subjective judgments and judgments about subjects. A distinction regarding judgments of perception [English] It is well known the number of problems that arise from the distinction between "judgments of perception" and "judgments of experience" delivered in the Prolegomena. This article focuses on the impossibility of assigning truth value to judgments of perception since it seems counterintuitive to indicate that judgments such as "I am cold" or "sugar tastes sweet" cannot be true. To solve this difficulty, it is proposed here to (...) distinguish between true judgments of perception (true subjective judgments) and "judgments about subjects". The latter would be those that, despite referring in a certain sense to a subject, do so using categorical links and, therefore, are judgments of experience with claims of objective validity and with truth value. However, there is another reason for this distinction besides solving the difficulty posed. Above all, it is important to offer a key to understand the true nature of judgments of perception, showing the impossibility of understanding them as judgments that describe subjective mental states, and trying to distinguish the way in which we enunciate them from the merely subjective unit that, according to Kant, characterizes them. To carry out these objectives, we will first analyze the basis of the distinction between perception judgments and experience judgments; secondly, a distinction between subjective judgments and judgments about subjects is proposed and explained, while the role of truth in the empirical illusion is examined; and finally, we will underline the impossibility of formulating judgments (including those of perceptions) independently of any objective link. [Español] Es moneda común la diversidad de problemas que plantea la introducción de la distinción entre “juicios de percepción” y “juicios de experiencia” en los Prolegómenos. Este trabajo centra su atención en la imposibilidad de asignar valor de verdad a juicios de percepción —dada su carencia de pretensión de validez objetiva— pues parece contraintuitivo indicar que juicios como “tengo calor” o “el azúcar me sabe dulce” no pueden ser verdaderos. Para solucionar esta dificultad, se propone aquí distinguir entre los verdaderos juicios de percepción (verdaderos juicios subjetivos) y “juicios sobre sujetos”. Estos últimos serían aquellos que, a pesar de referirse en cierto sentido a un sujeto, lo hacen con enlaces categoriales y, por tanto, son en realidad juicios de experiencia con pretensión de validez objetiva y con valor de verdad. Sin embargo, a esta distinción subyace otro motivo además de solucionar la dificultad planteada. Interesa, sobre todo, ofrecer una clave para comprender la verdadera naturaleza de los juicios de percepción, mostrando la imposibilidad de entenderlos como juicios que describen estados mentales subjetivos, e intentando distinguir la forma en que los enunciamos de la unidad meramente subjetiva que, según Kant, los caracteriza. Para llevar a cabo estos objetivos se analiza, primero, el fundamento de la distinción entre juicios de percepción y juicios de experiencia; en segundo lugar, se propone y explica la distinción entre juicios subjetivos y juicios sobre sujetos, a la par que se examina el papel de la verdad en la ilusión empírica; y por último se subraya la imposibilidad de formular juicios (incluso de percepción) independientemente de cualquier enlace objetivo.

Conceptualism is the view that cognizers can have mental representations of the world only if they possess the adequate concepts by means of which they can specify what they represent. By contrast, non-conceptualism is the view that mental representations of the world do not necessarily presuppose concepts by means of which the content of these representations can be specified, thus cognizers can have mental representations of the world that are non-conceptual. Consequently, if conceptualism is true then non-conceptualism must be false, (...) and vice versa. This incompatibility makes the current debate over conceptualism and non-conceptualism a fundamental controversy since the range of conceptual capacities that cognizers have certainly has an impact on their mental representations of the world, on how sense perception is structured, and how external world beliefs are justified. Conceptualists and non-conceptualists alike refer to Kant as the major authoritative reference point from which they start and develop their arguments. The appeal to Kant attempts to pave the way for a robust answer to the question of whether or not there is non-conceptual content. Since the incompatibility of the conceptualist and non-conceptualist readings of Kant indicate a paradigm case, hopes have risen that the answer to the question of whether Kant is a conceptualist or a non-conceptualist might settle the contemporary controversy across the board. This volume searches for that answer. This book is based on a special issue of the International Journal of Philosophical Studies. (shrink)

International Journal of Philosophical Studies, Volume 19, Issue 3, Page 319-322, July 2011.

This article addresses three questions concerning Kant’s views on non-rational animals: do they intuit spatio-temporal particulars, do they perceive objects, and do they have intentional states? My aim is to explore the relationship between these questions and to clarify certain pervasive ambiguities in how they have been understood. I first disambiguate various nonequivalent notions of objecthood and intentionality: I then look closely at several models of objectivity present in Kant’s work, and at recent discussions of representational and relational theories of (...) intentionality. I argue ultimately that, given the relevant disambiguations, the answers to all three questions will likely be positive. These results both support what has become known as the nonconceptualist reading of Kant, and make clearer the price the conceptualist must pay to sustain her position. (shrink)

I examine the division of labor between the Metaphysical Deduction (MD) and the Transcendental Deduction (TD). Against a common reading, I argue that the MD is insufficient to prove the a priori origin of the categories. For both Kant and his main opponent, namely Hume, the question of whether the categories have an a priori origin in the pure understanding is inseparable from the question of whether they have objective validity. Since the MD does not establish the objective validity of (...) the categories, it cannot establish their a priori origin either. The MD is nevertheless an indispensable part of Kant's project because it lays the argumentative groundwork for the proof structure of the TD and because it provides the systematic plan for the future metaphysics of experience.

I present an argument for an interpretation of Kant's views on the nature of the ‘content [Inhalt]’ of ‘cognition [Erkenntnis]’. In contrast to one of the longest standing interpretations of Kant's views on cognitive content, which ascribes to Kant a straightforwardly psychologistic understanding of content, and in contrast as well to the more recently influential reading of Kant put forward by McDowell and others, according to which Kant embraces a version of Russellianism, I argue that Kant's views on this topic (...) are of a much more Fregean bent than has traditionally been admitted or appreciated. I conclude by providing a sketch of how a better grasp of Kant'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 chapter spells out in detail how Kant’s thinking about logic during the critical period shapes the account of philosophy that he gives in the Critiques. Tolley explores Kant’s motivations behind his formation of the idea of a new “transcendental” logic, drawing out in particular how he means to differentiate it from the traditional “merely formal” approaches to logic, insofar as transcendental logic investigates not just the basic forms of the activity of thinking but also its basic contents. Kant’s understanding (...) of both of these logics directly factor into the first Critique’s more general project of the critique of reason in particular, as not just a capacity for a certain kind of thinking (inferring), but as a possible source of a priori cognition.

Kant's Critique of Judgment has often been interpreted by scholars as comprising separate treatments of three uneasily connected topics: beauty, biology, and empirical knowledge. Rachel Zuckert's book interprets the Critique as a unified argument concerning all three domains. She argues that on Kant's view, human beings demonstrate a distinctive cognitive ability in appreciating beauty and understanding organic life: an ability to anticipate a whole that we do not completely understand according to preconceived categories. This ability is necessary, moreover, for human (...) beings to gain knowledge of nature in its empirical character as it is, not as we might assume it to be. Her wide-ranging and original study will be valuable for readers in all areas of Kant's philosophy. (shrink)

This book traces a deep misunderstanding about the relation of concepts and reality in the history of philosophy. It exposes the influence of the mistake in the thought of Locke, Berkeley, Kant, Nietzche and Bradley, and suggests that the solution can be found in Hegelian thought. Ellis argues that the treatment proposed exemplifies Hegel's dialectical method. This is an important contribution to this area of philosophy.

В настоящата книга се изследва идеята за случайността през нейното историческо и концептуално развитие и са отделени пет основни и типични понятия. Анализът тръгва от класическите примери – Платон, Аристотел, Кант и Хегел – и стига до съвременния контекст на случайността, който е представен през теорията на вероятностите и теорията на сложността. Някои от изведените понятия са формализирани и имат по-логически, математически или пък информационен характер, а други са по-скоро физически или субектни, но всички те са представени в една обща (...) историческа типология. В нея се включва и парадигмата срещу случайността, която има теоретична, културна и дори органична природа. (shrink)

I defend a novel interpretation of Kant's conceptualism regarding the contents of our perceptual experiences. Conceptualist interpreters agree that Kant's Deduction aims to prove that intuitions require the categories for their spatiality and temporality. But conceptualists disagree as to which features of space and time make intuitions require the categories. Interpreters have cited the singularity, unity, infinity, and homogeneity of space and time. But this is incompatible with Kant's Aesthetic, which aims to prove that these same features qualify space and (...) time as intuitions, not concepts. On my interpretation, the feature is objectivity. Space and time are objective, in that they ground our judgments in geometry and mechanics. (shrink)
