Kant: Critique of Pure Reason

The concept of the highest good is an important but hardly uncontroversial piece of Kant’s moral philosophy. In the considerable literature on the topic, challenges are raised concerning its apparently heteronomous role in moral motivation, whether there is a distinct duty to promote it, and more broadly whether it is ultimately to be construed as a theological or merely secular ideal. Yet comparatively little attention has been paid to the context of a doctrine that had enjoyed a place of prominence (...) in the ethical systems of the ancients, where these systems provided a key critical foil for the development of Kant’s own conception of the highest good in terms of “happiness distributed in exact proportion to morality” (cf. 5:110). Indeed, these ethical systems prove important for Kant not only in his initial presentation of his account in the Canon of Pure Reason in the first Critique, where he sought to redress the errors of the Epicurean and Stoic conception in particular, but also and importantly in the course of his development towards the second Critique. As I argue in this paper, Christian Garve’s defense of a revised but recognizably Stoic conception of the highest good in his translation of and commentary on Cicero’s De officiis (On Duties), helps to account for Kant’s renewed attention to that doctrine, and specifically to the errors attending the Stoic version, in the Dialectic of Pure Practical Reason.

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

I review Karin de Boer's "Kant's Reform of Metaphysics: The Critique of Pure Reason Reconsidered" (Cambridge UP, 2020) for Kant-Studien.

The aim of the Schematism chapter of the Critique of Pure Reason is to solve the problem posed by the “inhomogeneity” of intuitions and categories: the sensible properties of objects represented in intuition are of a different kind than the properties represented by categories. Kant's solution is to introduce what he calls “transcendental schemata,” which mediate the subsumption of objects under categories. I reconstruct Kant's solution in terms of two substantive premises, which I call Subsumption Sufficiency (i.e., that subsuming an (...) object under a transcendental schema is sufficient to subsume it under the corresponding category) and Real Possibility (i.e., that it is really possible to subsume objects under each of the transcendental schemata). These two principles, together with a trivial modal one (the Subsumption-Possibility Link), entail that it is possible to subsume objects under categories; in other words, the argument of the Schematism is valid. The main work of the paper consists in reconstructing Kant's arguments for, and explanations of, these premises. I argue that they hinge on Kant's claim that transcendental schemata are “time-determinations,” which I interpret to mean: rules for reflexively representing the temporal relations among our own representational states. On the basis of this reading, I reconstruct Kant's argument for Subsumption Sufficiency, category by category. I also explain why Real Possibility follows almost immediately. Granting Kant the argument up to this point in the Critique, the argument of the Schematism is sound. (shrink)

The aim of the Analytic of Concepts is to derive and deduce a set of pure concepts of the understanding, the categories, which play a central role in Kant’s explanation of the possibility of synthetic a priori cognition and judgment. This chapter is structured around two questions. First, what is a pure concept of the understanding? Second, what is involved in a deduction of a pure concept of the understanding? In answering the first, we focus on how the categories differ (...) from the pure forms of sensibility and examine whether they are known only to be the pure forms of human thinking or rather the forms of discursive cognition as such. In answering the second, we draw a distinction between the application and the exemplification of the categories and use it to identify different ways of understanding Kant’s project in the Transcendental Deduction of the Categories. These questions connect because the answer to the first determines how we should understand the kind of entitlement which is to be established in the Deduction. (shrink)

In this paper I propose a novel interpretation of Kant’s proof of the existence of the outer world in the Refutation of Idealism. According to this interpretation, Kant’s proof does not provide a regressive explanation of our capacity to determine the temporal order of our experiences. Rather, it expresses a counterfactual reflection on what it takes for something to be actual in contrast to being merely imagined. On the ground of this reflection, Kant argues against the Cartesian sceptic that, even (...) if all our representations of empirical objects other than ourselves failed to be veridical, we would still know a priori that in every situation in which we, as thinking things, actually exist, something outside us in space must necessarily exist. (shrink)

This work examines Kant’s remarkable decision to rewrite the core argument of the first Critique, the Transcendental Deduction of the Categories. I identify a two-part structure common to both versions: first establishing an essential role for the categories in unifying sensible intuitions; and then addressing a worry about how the connection between our faculties asserted in the first part is possible. I employ this structure to show how Kant rewrote the argument, focusing on Kant’s response to the concerns raised in (...) an early review by Johann Schultz. Schultz’s dissatisfaction with the original Deduction lies in its second part, and Kant’s subsequent revisions are focused on providing a better answer to this how-possible question. The new Deduction offers a more direct and convincing account of how our faculties work together to make experience possible. (shrink)

In the Critique of Pure Reason, Kant draws a distinction between appearances and things in themselves, characterizing the latter as uncognizable. While arguing that all we can cognize are appearances, Kant nevertheless maintains that there are thing in themselves. This has struck many as questionable: how can we be in a position to affirm, of things stipulated to be uncognizable, that they exist? In this paper, I take up the challenge of establishing the existence of things in themselves. I begin (...) by making the case that, given Kant’s epistemological strictures, the existence of things in themselves must follow analytically from the existence of appearances. After examining the pitfalls of a recent attempt at establishing the existence of things in themselves, I go on to argue that the feature of appearances in virtue of which their existence analytically entails the existence of themselves is the subjectivity of their form. It is implicit in the notion of something with a subjective form that its matter is provided via affection from without. Moreover, the things providing the matter of appearances can’t be located in space and time, because appearances themselves depend on our sensibility for their formal features. (shrink)

I raise three questions relevant to De Boer’s overall project in Kant’s Reform of Metaphysics. The first is whether Kant’s 1799 open letter to Fichte supports or threatens her contention that Kant had an abiding interest in developing a reformed metaphysics from 1781 onwards. The second is whether De Boer’s conception of the pure intellect and its place in Kant’s projected system of metaphysics captures the role of pure sensibility in the Analytic of Principles, rational physics and rational psychology. The (...) third is whether one might accept the outline of this system as De Boer develops it while still holding that it is more accurate to characterize it as revolution rather than reform. (shrink)

For Kant, the human cognitive faculty has two sub-faculties: sensibility and the understanding. Each has pure forms which are necessary to us as humans: space and time for sensibility; the categories for the understanding. But Kant is careful to leave open the possibility of there being creatures like us, with both sensibility and understanding, who nevertheless have different pure forms of sensibility. They would be finite rational beings and discursive cognizers. But they would not be human. And this raises a (...) question about the pure forms of the understanding. Does Kant leave open the possibility of discursive cognizers who have different categories? Even if other discursive cognizers might not sense like us, must they at least think like us? We argue that textual and systematic considerations do not determine the answers to these questions and examine whether Kant thinks that the issue cannot be decided. Consideration of his wider views on the nature and limits of our knowledge of mind shows that Kant could indeed remain neutral on the issue but that the exact form his neutrality can take is subject to unexpected constraints. The result would be an important difference between what Kant says about discursive cognizers with other forms of sensibility and what he is in a position to say about discursive cognizers with other forms of understanding. Kantian humility here takes on a distinctive character. (shrink)

The problem at the center of this essay is how one can reconcile the continuity of space with a monadological theory of matter, according to which matter is ultimately composed of simple elements, a problem that greatly exercised Leibniz, the Wolffians, and Kant. The underlying purpose of this essay is to illustrate my reading of Kant’s philosophical development, and of his relation to the Wolffians and Leibniz, according to which, (a), this development was fueled by ‘home-grown’ problems that arose within (...) the framework of the Wolffian philosophy from which Kant started out, and, (b), on his journey to critical idealism, Kant gradually moved away from Wolffianism, but closer to Leibniz, which, however, he came to realize only some years after the publication of the Critique of Pure Reason. This reading is illustrated by showing that the problem of how to reconcile the continuity of space with a monadological theory of matter is a problem that Kant inherits from Leibniz and the Wolffians, in whose thinking it already plays an important role, that Leibniz’s mature solution to the problem differs markedly from the Wolffian solution, and that Kant’s early, pre-critical solution is largely Wolffian, while his later critical solution is largely Leibnizian, as he himself notes with gleeful satisfaction. The discussion also reveals that this problem is one of the key problems that fueled Kant’s philosophical development and, eventually, led him to the discovery of transcendental idealism. (shrink)

I critically examine one central line of reasoning in Mario Caimi's book »Kant's B Deduction« (Cambridge Publishing, 2014).

In his book, The Bounds of Sense, P. F. Strawson commented that Immanuel Kant’s argument in the second analogy “proceeds by a non sequitur of numbing grossness,” causing a fair amount of debates. Kant’s task in the second analogy is to argue that every event has a cause. Strawson criticizes Kant by claiming that in his argument, Kant not only changes the content of necessity but also shifts a conceptual necessity to a causal one. In this paper, I defend Kant’s (...) second analogy against Strawson’s objection by arguing that Strawson misinterprets Kant’s strategy. (shrink)

I argue that Kant thought his Transcendental Deduction of the Pure Concepts could reach skeptical empiricists like Hume by providing an overlooked explanation of the mind's a priori relation to the objects of experience. And he thought empiricists may be motivated to listen to this explanation because of an instability and dissatisfaction inherent to empiricism.

Los noumena son, en principio, conceptos límites. En el corpus kantiano encontramos múltiples de ellos, cuyo papel es decisivo en el tratamiento de la metafísica anterior, así como en la propuesta de metafísicas alternativas. Kant, sin embargo, no se detiene a explicarnos de dónde surgen esos conceptos y dónde irían. La presente investigación sugiere que a partir del concepto de nota (Merkmal) presentada en la KrV y desarrollada en la Jäsche Logik, podemos comprender estos noumena como las notas analíticas, suficientes, (...) esenciales y primitivas de las ideas de la razón, tanto teóricas como prácticas. (shrink)

In the Second Analogy, Kant argues that every event has a cause. It remains disputed what this conclusion amounts to. Does Kant argue only for the Weak Causal Principle that every event has some cause, or for the Strong Causal Principle that every event is produced according to a universal causal law? Existing interpretations have assumed that, by Kant’s lights, there is a substantive difference between the two. I argue that this is false. Kant holds that the concept of cause (...) contains the notion of lawful connection, so it is analytic that causes operate according to universal laws. He is explicit about this commitment, not least in his derivation of the Categorical Imperative in Groundwork III. Consequently, Kant’s move from causal rules to universal laws is much simpler than previously assumed. Given his commitments, establishing the Strong Causal Principle requires no more argument than establishing the Weak Causal Principle. (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)

Each of Kant’s three Critiques offers an account of the nature of a mental faculty and arrives at this account by means of a procedure I call ‘faculty analysis’. Faculty analysis is often regarded as among the least defensible aspects of Kant’s position; as a consequence, philosophers seeking to inherit Kantian ideas tend to transpose them into a different methodological context. I argue that this is a mistake: in fact faculty analysis is a live option for philosophical inquiry today. My (...) argument is as follows: Faculty analysis is a live option for certain kinds of philosophical theories if so-called “agentialist” views about the nature of belief are correct. There are good reasons for thinking that such views are correct. So faculty analysis should not be dismissed out of hand. Since the first premise in this argument bears a lot of weight, a large part of the paper is devoted to clarifying and defending it, in part by arguing that Kant himself holds a version of agentialism about belief.

Dieses Buch dient einem umfassenden Verständnis von Kants Lehre der Struktur des Bewusstseins und des Selbstbewusstseins. Eine facettenreiche Theorie zu diesem Thema lässt sich mit Hilfe des zeitgenössischen begrifflichen Instrumentariums aus den über das Kantische Opus verstreuten Textressourcen herausarbeiten. Mit dieser Rekonstruktion lassen sich viele, scheinbar unüberwindbare, exegetische Unklarheiten aufhellen.

Thorough comparison of Immanuel Kant’s and Christian Wolff’s divergent appraisals of the science of psychology reveals various ways in which Kant fundamentally altered the Wolffian philosophical apparatus that he inherited. Wolff conceived of a thoroughgoing interplay between empirical and rational psychology, of combining different sorts of cognition in psychology, and of a mathematical science of the soul, or psychometrics. Kant however rejected each of these particular theses and deemed psychology to be no natural science, “properly so-called.” This chapter details these (...) departures from Wolff, explains their basis, and concretizes an underlying contrast in Kant’s and Wolff’s respective philosophical approaches. Namely, whereas Wolff’s philosophical system is malleable, allowing for the combination of various kinds of cognition and methods, in Kant’s Critical philosophy, everything has its proper, preordained niche. At bottom, it is the unyielding rigor of Kant’s system that results in his pessimistic evaluation of the prospects for psychology. (shrink)

The book addresses two main areas of Kant’s theoretical philosophy: the doctrine of transcendental idealism and various central aspects of the arguments from the Metaphysical and Transcendental Deductions, as well as the relation between the deduction argument and idealism. -/- Among the topics covered are the nature of objective validity, the role and function of transcendental logic in relation to general or formal logic, the possibility of contradictory thoughts, the meaning of the Leitfaden at A79 and the unity of cognition, (...) the two-steps-in-one-proof interpretation and categorial instantiation, categorial illusion, Strawson’s transcendental argument, the persistently perplexing question of the derivation of the categories, and the relation between apperception, objectivity, judgement, and idealism. -/- With regard to idealism in particular, the focus is on the metaphysical two-aspect interpretation and its problems, on the merits and demerits of the controversial phenomenalist reading of Kant’s idealism, and on the topic of subjectivism and epistemic humility. -/- In all of the aforementioned topics, the book presents wholly novel interpretations compared to the standard or mainstream interpretations.

Scholars working on Kant’s Anticipations of Perception generally attribute to him an argument that invalidly infers that objects have degrees of intensive magnitude from the premise that sensations do. I argue that this rests on an incorrect disambiguation of Kant’s use of Empfindung as referring to the mental states that are our sensings, rather than the objects that are thereby sensed. Kant’s real argument runs as follows. The difference between a representation of an empty region of space and/or time and (...) a representation of that same region as occupied by an object entails that, in addition to their extensive magnitude, objects must be represented as having a matter variable in intensive magnitude. Since it is the presence of sensation in a cognition that marks the difference between representing only the extensive magnitude of the object and the object as a whole, it is sensation that represents its intensive magnitude. (shrink)

I argue that Kant has developed a broad systematic account of the architectonic functionality of pure reason that can be used and advanced in contemporary contexts. Reason, in the narrow sense, is responsible for the picture of a well-ordered universe of science consisting of architectonic ideas of science, sciences and parts of sciences. In the first section (I), I show what Kant means by the architectonic ideas by explaining and interrelating the concepts of (a) the faculty of reason, (b) ideas (...) (as principles), (c) method, and (d) sciences of reason. Thereafter (II), I think through his holistic understanding of science and scientific progress and suggest differentiating between four levels of use of architectonic ideas, drawing on the metaphor of a well-structured universe as imagined by Kant in his work on the Universal Natural History and Theory of the Heavens. I also claim that each possible idea of reason can be (apart from its primary function) additionally regarded as a fourth-level architectonic concept when explicitly conceived as an object of (e. g. philosophical) studies, i. e. from a mere methodological perspective. In the final section (III), I unveil the potential of Kant’s theory by pointing out how this architectonic methodological function of pure reason is tacitly used in Karl-Otto Apel’s contemporary philosophical research programme.

Kant's Critique of Pure Reason, his main work of theoretical philosophy, frequently uses metaphors from law. In this first book-length study in English of Kant's legal metaphors and their role in the first Critique, Sofie Møller shows that they are central to Kant's account of reason. Through an analysis of the legal metaphors in their entirety, she demonstrates that Kant conceives of reason as having a structure mirroring that of a legal system in a natural right framework. Her study shows (...) that Kant's aim is to make cognisers become similar to authorized judges within such a system, by proving the legitimacy of the laws and the conditions under which valid judgments can be pronounced. These elements consolidate her conclusion that reason's systematicity is legal systematicity. (shrink)

Few of Kant’s distinctions have generated as much puzzlement and criticism as the one he draws in the Prolegomena between judgments of experience, which he describes as objectively and universally valid, and judgments of perception, which he says are merely subjectively valid. Yet the distinction between objective and subjective validity is central to Kant’s account of experience and plays a key role in his Transcendental Deduction of the categories. In this paper, I reject a standard interpretation of the distinction, according (...) to which judgments of perception are merely subjectively valid because they are made without sufficient investigation. In its place, I argue that for Kant, judgments of perception are merely subjectively valid because they merely report sequences of perceptions had by a subject without claiming that what is represented by the perceptions is connected in the objects the perceptions are of. Whereas the interpretation I criticize undercuts Kant’s strategy in the Deduction, I argue, my interpretation illuminates it. (shrink)

Haben wir einen intentionalen Zugriff auf die Außenwelt und ist diese von unseren geistigen Zuständen abhängig? Dieser Band liefert einen Beitrag zur Lösung dieses Problems der Realismusdebatte. Ausgehend von Kants Unterscheidung zwischen Sinnlichkeit und Spontaneität wird die Rolle begrifflicher Fähigkeiten in der Anschauung im Lichte zeitgenössischer Theorien bewertet. Anhand der Kritik der reinen Vernunft wird ein Ansatz entwickelt, der unter Rückgriff auf das "transzendentale Subjekt "eine Alternative zu materialistischem Fundamentalismus und strengem Konzeptualismus bietet.

In this paper, I consider whether a reading of Kant's solution to the Third Antinomy can offer material for devising a new model of transcendental argument. The problem that this form of argument is meant to address is an antinomy between two apparently contradictory claims, q and ¬q, where we seem equally justified in holding both. The model has the following form: p; q is a necessary condition of p; the only justification we have for q is that it is (...) a necessary condition of p; p is justified only in domain X (where X is a domain of objects of cognition); therefore, q is justified only in domain X. Because the argument shows that our justification for q is valid only in X, it also establishes that there is conceptual space to hold ¬q outside of X. (shrink)

This paper is a novel attempt at reconstructing Kant’s account of self-consciousness in the first Critique by making evident its gradual expository progression, and at identifying the epistemic status of the two modes of self-consciousness: pure and empirical. I trace the gradual exposition of theoretical self-consciousness across three crucial parts of the book: the Transcendental Deduction, the Refutation of Idealism, and the Paralogisms of Pure Reason. In doing so, I show that the account of theoretical self-consciousness is not presented to (...) us all at once, but is progressively expanded and filled in. I also emphasize the importance of the distinction between the subject’s awareness of its existence, “Dasein”, and of its existence, “Existenz”. I conclude by discussing Kant’s preliminary remarks about practical self-consciousness in the Paralogisms, which bear an important relation to theoretical self-consciousness. (shrink)

In light of the central role scientific research plays in Merleau-Ponty’s phenomenology, the question has arisen whether his phenomenology involves some sort of commitment to naturalism or whether it is better understood along transcendental lines. In order to make headway on this issue, I focus specifically on Merleau-Ponty’s method and its relationship to Kant’s transcendental method. On the one hand, I argue that Merleau-Ponty rejects Kant’s method, the ‘method-without-which’, which seeks the a priori conditions of the possibility of experience. On (...) the other hand, I show that this does not amount to a methodological rejection of the transcendental altogether. To the contrary, I claim that Merleau-Ponty offers a new account of the transcendental and a priori that he takes to be the proper subject matter of his phenomenological method, the method of ‘radical reflection’. And I submit that this method has important affinities with aesthetic themes in Kant’s philosophy. (shrink)

Name der Zeitschrift: Kant-Studien Jahrgang: 110 Heft: 2 Seiten: 308-317.

It is an essential part of Kant's conception of regulative principles and ideas that those principles and ideas are in a certain sense indeterminate. The relevant sense of indeterminacy is cashed out in a section in the Antinomies where Kant says that the regress of conditions of experience forms not a “regressus in infinitum” but a “regressus in indefinitum.” The mathematics that Kant appears to rely on in making this distinction turns out to be problematic, as Jonathan Bennett showed long (...) ago. But I suggest that despite this, there is another mathematically legitimate way to make Kant's point, one enunciated by, among others, Michael Dummett. This reading is corroborated, I suggest, by Kant's conception of reason as a radically open-ended endeavor. -/- . (shrink)

This book focuses on the unity, diversity, and centrality of the notion of law as it is employed in Kant's theoretical and practical philosophy. Eric Watkins argues that, by thinking through a number of issues in various historical, scientific, and philosophical contexts over several decades, Kant is able to develop a univocal concept of law that can nonetheless be applied to a wide range of particular cases, despite the diverse demands that these contexts give rise to. In addition, Watkins shows (...) how Kant comes to view both the generic conception of law which he develops and its different particular instances as crucial components of his systematic philosophy as a whole. This volume's new and unified account of a major current running through Kant's work will be important for scholars interested in numerous aspects of his philosophy, from the theoretical and abstract to the practical and empirical.

It is often claimed that the structure of the Transcendental Logic is modeled on the Wolffian division of logic textbooks into sections on concepts, judgments, and inferences. While it is undeniable that the Transcendental Logic contains elements that are similar to the content of these sections, I believe these similarities are largely incidental to the structure of the Transcendental Logic. In this essay, I offer an alternative and, I believe, more plausible account of Wolff’s influence on the structure of the (...) Transcendental Logic, one that puts the focus on his empirical psychology rather than his logic. In particular, I argue that the structure of the Transcendental Logic is deeply indebted to a conception of purity that Wolff introduces in his empirical psychology and that this conception sheds more light on the overall structure of the Transcendental Logic than the accepted view. In section one, I outline two conceptions of purity found in Kant and trace them to similar views in Wolff. In section two, I turn to Kant’s views about logic as they are expressed in the Critique and argue that it is best to interpret Kant’s taxonomy of logic on its own terms rather than reading it through its terminological similarities to aspects of the Wolffian tradition. In section three, I argue that the second of the two conceptions of purity identified in section one is central to the structure of the Transcendental Logic. In doing so, I argue against the widespread view that this section of the Critique is modeled solely on what Kant calls pure general logic as opposed to both pure and applied general logic. I then conclude by briefly reviewing my account and considering some of its broader implications for our understanding of Kant. (shrink)

The importance of the pure concepts of the understanding (i.e. the categories) within Kant’s system of philosophy is undeniable. As I hope to make clear in this essay, however, the categories are also an essential part of Kant’s critique of Christian Wolff. In particular, I argue that Kant’s development of the categories represents a decisive break with the Wolffian conception of the understanding and that this break is central to understanding the task of the Transcendental Analytic. This break, however, is (...) not merely that Kant affirms while Wolff and his followers deny a sharp distinction between sensibility and the understanding, which is the aspect of Kant’s rejection of Wolff that scholars most frequently note. Rather, this break concerns differences in their views about the understanding itself. For while Wolff conceives of the understanding as a mental capacity to extract and make distinct content already present in the senses, Kant conceives of the understanding in its “real use” as a capacity to produce purely intellectual content.

Como escreveu Thomas Huxley “O que é conhecido é finito, o que é desconhecido infinito...”1. Aqui temos que ter em nossa imaginação que esse desconhecimento não significa não saber nada a respeito. Podemos dizer até que existe uma finitude no conhecimento do infinito.Isso não é conhecer a existência dos infinitos, e utilizar parte deles, como números, por exemplo. E para poder utiliza-los, recortamos parte da infinitude e agrupamos aquela parte que nos interessa. Também é preciso a compreensão de que não (...) é possível conhecer totalmente o que é o infinito, pois levaria um tempo também infinito e, qual seria a referência? -/- . (shrink)

Kant conceives of chemical dissolutions as involving the infinite division and subsequent blending of solvent and solute. In the resulting continuous solution, every subvolume contains a uniform proportion of each reactant. Erich Adickes argues that this account stands in tension with other aspects of Kant’s Critical philosophy and his views on infinity. I argue that although careful analysis of Kant’s conception of dissolution addresses Adickes’ objections, the infinite division inherent to the process is beyond our human cognition, for Kant. Nevertheless, (...) such infinite division may be considered as an idea of reason to make comprehensible chemical reactions, revealing reason to play a pivotal role in the foundations of chemistry.

I argue that the understanding's spontaneity is only manifest in its purely logical use.

Conquanto seja utilizada somente no terceiro capítulo da Doutrina Transcendental do Método, designado “A arquitetônica da razão pura”, a distinção entre conhecimento histórico e conhecimento racional é um topos básico das Lógicas de Kant, marcando a diacronia de suas reflexões metafísicas. No percurso aqui proposto para esclarecer essas duas noções, remontamos a Christian Wolff. Para situar a posição epistemológica da Filosofia, no Discurso preliminar sobre a filosofia em geral, Wolff explicita a diferença entre os conhecimentos histórico, filosófico e matemático, na (...) tentativa de alocar toda a aquisição do nosso conhecimento no interior dessa tripartição. Kant acolhe essa divisão tripartite, mas vai reduzi-la à oposição entre conhecimento histórico e conhecimento racional, equacionando o conhecimento empírico com o histórico, e situando filosofia e matemática no interior do último modo de conhecimento. Procurou-se aqui mostrar que essas duas noções decisivas e contrapostas são conversíveis entre si, articulando-se no interior daquilo que Kant denomina uma arquitetônica. Mediante essa distinção, Kant procura um princípio metodológico de unificação, opondo as noções de agregação e subordinação, que darão origem às noções de agregado e sistema. Sendo ciência sistemática, a filosofia é projetada no vértice da disposição racional de todas as ciências, guardando consigo a responsabilidade de abrigar a meta final de todo o uso da razão humana.

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)

The Question of Truth in Kant’s Transcendental Logic [English] In the third section of the “Introduction” to transcendental logic, Kant dedicates a couple of paragraphs to the subject of truth (KrV B82-83). Based on this passage, Kant’s com¬mentators have justified various and sometimes contradictory interpretations of the Kantian notion of truth. However, few have analyzed the passage in its own context, that is, as part of the strategy to introduce the idea of transcendental logic. In this work, I intend to (...) take a position in this regard. I will try to show that this passage does not subscribe to the distinction between general and transcendental logic, but between analytic and dialectic logic. [Español] En la tercera sección de la “Introducción” a la lógica trascendental, Kant dedica un par de párrafos al tema de la verdad (KrV B82-83). Basándose en este pasaje, los comentaristas de Kant han justificado diversas y a veces contradictorias interpretaciones de la noción kantiana de verdad. Sin embargo, pocos han analizado el pasaje en su propio contexto, es decir, como parte de la estrategia para introducir la idea de una lógica trascendental. En este trabajo se pretende tomar postura a este respecto. Se intentará mostrar que este pasaje no abona a la distinción entre lógica general y lógica trascendental, sino entre analítica y dialéctica. (shrink)

In Glauben und Wissen, Hegel criticizes Kant for drawing a deep division between sensibility and understanding. Hegel suggests that Kant’s faculty of productive imagination is a step toward uniting intuition and concept in an original unity out of which the two arise, but this requires him to treat the productive imagination in ways Kant would not approve. I argue that Kant’s doctrine of the schematism offers an advance on the productive imagination when it comes to solving the intuition/concept dualism Hegel (...) critiques, although there remain serious problems with which Hegel would take issue. Although the schematism might answer some of the criticisms Hegel aims at the intuition/concept dualism, it does not solve the related problem Hegel finds in Kant, namely the dualism of cognition and thing-in-itself.
