The common assumption that the Transcendental Deduction aims to refute scepticism often leads interpreters to conclude that it fails and even that Kant is confused about what it is supposed to achieve. By examining what Kant himself says concerning the Deductions' relation to scepticism, this article seeks to determine what sort of scepticism he has in view and how he responds to it. It concludes that the Deduction aims neither to refute Cartesian, outer- world scepticism nor to (...) refute Humean, empiricist scepticism, and it outlines an alternative conception of the Deduction's task, as one of reconciling apparently conflicting claims of reason.

James Van Cleve has argued that Kant’s Transcendental Deduction of the categories shows, at most, that we must apply the categories to experience. And this falls short of Kant’s aim, which is to show that they must so apply. In this discussion I argue that once we have noted the differences between the first and second editions of the Deduction, this objection is less telling. But Van Cleve’s objection can help illuminate the structure of the B (...) class='Hi'>Deduction, and it suggests an interesting reason why the rewriting might have been thought necessary. (shrink)

This paper deals with a foundational aspect of Integrated Information Theory of consciousness: the nature of the relation between the axioms of phenomenology and the postulates of cause-effect power. There has been a lack of clarity in the literature regarding this crucial issue, for which IIT has received much criticism of its axiomatic method and basic tenets. The present contribution elucidates the problem by means of a categorial analysis of the theory’s foundations. Its main results are that: IIT has a (...) set of nine fundamental concepts of reason, called categories, which constitute its categorial lexicon and through which it formulates a system of principles incorporating the axioms, the postulates, and the central identity; and the connection between the axioms and postulates is grounded by their common root in this categorial lexicon, the categories of which find their justification by means of a phenomenological and transcendental deduction. Some further results are the unique origin of axioms and postulates in the categories; the distinction between conceptual and formalized postulates; a clarification of the uniqueness problem of categorial lexica in general; and an IIT account of objectivity by explicating how the physical is defined by means of categories. All of this is put to use against various criticism targeting IIT’s theoretical core. If successful, the proposed interpretation illuminates a central issue in the contemporary study of consciousness and contributes to an environment of mutual understanding between defenders and critics of the theory.

One of the strongest motivations for conceptualist readings of Kant is the belief that the Transcendental Deduction is incompatible with nonconceptualism. In this article, I argue that this belief is simply false: the Deduction and nonconceptualism are compatible at both an exegetical and a philosophical level. Placing particular emphasis on the case of non-human animals, I discuss in detail how and why my reading diverges from those of Ginsborg, Allais, Gomes and others. I suggest ultimately that it (...) is only by embracing nonconceptualism that we can fully recognise the delicate calibration of the trap which the Critique sets for Hume. (shrink)

Fregean predicates applied to Fregean objects are merely defined by a `timeless' deductive order of sentences. They cannot provide sufficient structure in order to explain how names can refer to objects of intuition and how predicates can express properties of substances that change in time. Therefore, the accounts of Wilson and Quine, Prior and Brandom for temporal judgments fail — and a new reconstruction of Kant's transcendental logic, especially of the analogies of experience, is needed.

Henry E. Allison presents an analytical and historical commentary on Kant`s transcendental deduction of the pure concepts of the understanding in the Critique of Pure Reason. He argues that, rather than providing a new solution to an old problem, it addresses a new problem, and he traces the line of thought that led Kant to the recognition of the significance of this problem in his 'pre-critical' period. In addition to the developmental nature of the account of Kant`s views (...) presented here, two distinctive features of Allison's reading of the deduction are a defense of Kant`s oft criticized claim that the conformity of appearances to the categories must be unconditionally rather than merely conditionally necessary and an insistence that the argument cannot be separated from Kant`s transcendental idealism.

In this article, the author proposes to reconstruct Kant's "transcendental deduction" without in any way making use of the results of the so-called "metaphysical" one. His suggestion is that what Kant baptizes "pure concepts" or "categories" are in fact not "concepts" at all, strictly speaking, but rather the very forms of judgment from which these "concepts" were supposed to have been derived in the "metaphysical deduction". The task of the "transcendental" deduction is, then, to show (...) that such forms of judgment can legitimately be applied to empirical contents: to demonstrate, in other words, the possibility of empirical knowledge.

The aim of this paper is to exhibit some important features of the two versions of the deduction. In the first edition, Kant emphasizes the role of imagination as an autonomous faculty; in the second, On the contrary, Imagination, Though keeping its synthetic function, Is subordinated to the understanding. This reversal in the role of imagination is bound up to a paradoxical conception of the object which pervades the two editions of the "critique". The deduction should be conceived (...) as a way out of the paradox, Each edition favoring one alternative against the other. The role of the subject is correlative of the way the object is conceived: this article shows how german idealism radicalized kant's position in the first edition, And positivism, The second version, Though both were led to depart from kant's general requirement that knowledge was a result of the equilibrium of concepts and intuitions.

Major recent interpretations of Kant's first "critique" (wolff, Strawson, Bennett) have taken his transcendental deduction to be an argument from the fact of consciousness to the existence of an objective world. I argue that it is unclear such an argument can succeed and there are overwhelming reasons to believe kant understood his deduction as having a very different form, namely as moving from the premise that there is empirical knowledge to the conclusion that there are universally valid (...) pure categories. Detailed support for this contention is offered in an analysis of the second edition version of the deduction. (shrink)

The purpose of this paper is first to explain a general notion of transcendental deductions, of which the Kantian are special cases; next to show, and to illustrate by examples from Kant’s work, that no transcendental deduction can be successful; and thirdly to put one of Kant’s achievements in its proper light by substituting for his spurious distinction between metaphysical exposition and transcendental deduction, a revised notion of metaphysical exposition and of the philosophical tasks arising (...) out of it.

In this book, Alison Laywine considers the mystery of the Transcendental Deduction in Immanuel Kant's Critique of Pure Reason. What is it supposed to accomplish and how? Laywine argues that Kant's peculiar adaptation of his early account of a world is the key to this mystery. Collecting evidence from the Critique and other writings by Kant--in order to identify what he took himself to be doing on his own terms--she holds that Kant deliberately adapted elements of his early (...) metaphysics both to set the agenda of the Deduction and to carry it out. Laywine highlights how the most important metaphysical element in Kant's thought was his early account of a world; a world is not just the sum-total of all substances created by God, but a whole unified by the universal laws of community prescribed by God that externally relate any given substance to all others. From this conception of a world, Kant then extracted a way to conceive key elements in the Deduction: experience as the whole of all possible appearances unified by the universal laws human understanding gives to nature.

The argument of the Transcendental Deduction of the Categories in the Critique of Pure Reason is the deepest and most far-reaching in philosophy. In his new book, Robert Howell interprets main themes of the Deduction using ideas from contemporary philosophy and intensional logic, thereby providing a keener grasp of Kant's many subtleties than has hitherto been available. No other work pursues Kant's argument through every twist and turn with the careful, logically detailed attention maintained here. Surprising new (...) accounts of apperception, the concept of an object, the logical functions of thought, the role of the Metaphysical Deduction, and Kant's relations to his Aristotelian-Cartesian background are developed. Howell makes a precise contribution to the discussion of most of the disputed issues in the history of Deduction interpretation. Controversial in its conclusions, this book demands the attention of all who take seriously the task of understanding Kant's work and evaluating it dispassionately. (shrink)

I take up Kant's remarks about a " transcendental deduction" of the "concepts of space and time". I argue for the need to make a clearer assessment of the philosophical resources of the Aesthetic in order to account for this transcendental deduction. Special attention needs to be given to the fact that the central task of the Aesthetic is simply the "exposition" of these concepts. The Metaphysical Exposition reflects upon facts about our usage to reveal our (...) commitment to the idea that these concepts refer to pure intuitions. But the legitimacy of these concepts still hangs in the balance: these concepts may turn out to refer to nothing real at all. The subsequent Transcendental Exposition addresses this issue. The objective validity of the concepts of space and time, and hence their transcendental deduction, hinges on careful treatment of this last point. (shrink)

The two major options on which the current debate on the interpretation of quantum mechanics relies, namely realism and empiricism, are far from being exhaustive. There is at least one more position available, which is metaphysically as agnostic as empiricism, but which shares with realism a committment to considering the structure of theories as highly significant. The latter position has been named transcendentalism after Kant. In this paper, a generalized version of Kant's method is used. This yields a reasoning that (...) one is entitled to call a transcendental deduction of some major formal features of quantum mechanics. (shrink)

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

In this paper, I argue that in the sense of greatest epistemological concern for Kant, empirical cognition is “rational sensory discrimination”: the identification or differentiation of sensory objects from each other, occurring through a capacity to become aware of and express judgments. With this account of empirical cognition, I show how the transcendental deduction of the first Critique is most plausibly read as having as its fundamental assumption the thesis that we have empirical cognition, and I provide evidence (...) that Kant understood Hume as granting this assumption. (shrink)

I first criticize strawson's account of the transcendental deduction, And then argue that wittgenstein's considerations (in his later work) of the rule-Governed nature of judgment can be used to reconstruct a valid argument for a certain kind of objectivity, Which excludes solipsims. I suggest how kant's talk of synthesis can be reinterpreted in the light of this, As indeed can the doctrine of empirical realism and transcendental idealism.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Kant's Transcendental Deduction by Alison LaywineKatherine DunlopAlison Laywine. Kant's Transcendental Deduction. Oxford: Oxford University Press, 2020. Pp. iv + 318. Hardback, $80.00.Alison Laywine's contribution to the rich literature on Kant's "Transcendental Deduction of the Categories" stands out for the novelty of its approach and conclusions. Laywine's declared "strategy" is "to compare and contrast" the Deduction with the Duisburg Nachlaß, an important (...) set of manuscript jottings from the 1770s (10). But her approach is also deeply informed by Kant's writings on metaphysics from the 1750s and 1760s; moreover, she gives attention to ancient Greek geometry and its importance for Kant's thought.I believe Laywine's most important interpretative claim is that the Transcendental Deduction's "final step" addresses "the question of how nature is possible" (210). Here, 'nature' is understood in what Kant calls the "formal sense," as "the totality of rules under which appearances must stand if they are to be thought as joined in one experience" (Prolegomena, §36; cf. B 165). This constitutes a novel answer to the problem posed in Dieter Henrich's landmark 1969 paper "The Proof Structure of the Transcendental Deduction" (Review of Metaphysics 22 [1969]: 640–59): how to understand §§21–26 of the (B-edition) Deduction as proving more than the thesis already stated in §20 (that the manifold in an intuition necessarily stands under the categories).Crucial support for Laywine's interpretation comes from §26 of the Deduction, which claims the possibility of cognizing objects "a priori through categories... as far as the laws of their combination are concerned, thus the possibility of as it were prescribing the law to nature and even making [nature] possible," is now "to be explained" (B 159). Kant does not use the term 'world' in this passage (as he does in Prolegomena §36). But Laywine contends that here the word 'nature' "has unmistakable, deliberate, cosmological connotations," and in fact "means 'world' in the sense of Kant's early cosmology": roughly, a whole unified by means of laws (12–13).The "cosmological" language of §26 does not recur in the following, officially concluding, section of the Deduction. So, we might ask whether Kant's explanation of how the understanding prescribes laws to nature is integral to the Deduction; Henry Allison, for instance, describes this explanation as an "appendix" (Kant's Transcendental Deduction: An Analytical-Historical Commentary [Oxford: Oxford University Press, 2015], 9). The question of whether it belongs integrally has bite because, as Laywine makes clear in her "Conclusion," the universal laws at issue are just the Analogies of Experience. Thus, the passage could be read as the "promissory note with a forward-looking reference to the System of Principles" that she finds missing from the Deduction (289). Laywine meets such worries by arguing that "the reappropriation [from the pre-Critical period] of the general cosmology is actually [End Page 162] doing... a lot of hard work" in the Deduction (13). This sustained argument comes to a head in chapter 4, which contends that each of the two steps into which Laywine divides the first half of the (B-edition) Deduction, treated in chapters 2 and 3 (respectively), relies on cosmological presuppositions.Chapter 2 analyzes the conception of knowledge as relation to an object that is asserted (in §17) to rely on the synthetic unity of apperception. Laywine traces this conception to the Duisburg Nachlaß's account of "exposition," which relates concepts a priori to appearances, in something like the way that geometrical construction relates them to pure intuition. (Laywine further connects the Latin term expositio to the Greek ekthesis, which expositio translates in the context of geometrical proof. She thereby gives the notion of ekthesis broader importance than does Jaakko Hintikka, who noted its relevance to Kant's philosophy of mathematics in "Kant on the Mathematical Method" [Monist 51 (1967): 352–75]. Laywine claims that Borelli's edition of Euclid could have been Kant's source for the term, but I doubt it was known to Kant and his contemporaries, since it is not among the editions cited by Christian Wolff; Commandino seems likelier to me. Chapter 2 is concerned to articulate the notion of... (shrink)

The paper offers a model of Kant's claim that unity of consciousness entails objectivity of experience. This claim has nothing especially to do with thought, language or the categories but is a general truth about arbitrary signaling systems of the sort modeled in the paper. In conclusion I draw some consequences for various forms of idealism.

This paper considers how Descartes's and Hume's sceptical challenges were appropriated by Christian Wolff and Johann Nicolaus Tetens specifically in the context of projects related to Kant's in the transcendental deduction. Wolff introduces Descartes's dream hypothesis as an obstacle to his account of the truth of propositions, or logical truth, which he identifies with the 'possibility' of empirical concepts. Tetens explicitly takes Hume's account of our idea of causality to be a challenge to the `reality' of transcendent concepts (...) in general, a challenge he addresses by locating the source of this concept in the understanding rather than in the imagination. After considering this background, I turn to Kant's deployment of apparently traditional sceptical concerns at the outset of the transcendental deduction and argue that he does not there intend to introduce a global sceptical challenge and, accordingly, that there are historical grounds for doubting that the transcendental deduction is intended as an anti-sceptical argument.

The subject of this article is a powerful objection to the non-conceptualist interpretation of Kant’s transcendental deduction of the categories. Part of the purpose of the deduction is to refute the sort of scepticism according to which there are no objects of empirical intuition that instantiate the categories. But if the non-conceptualist interpretation is correct, it does not follow from what Kant is arguing in the transcendental deduction that this sort of scepticism is false. This (...) article explains and assesses a number of possible responses to this objection. (shrink)

This book is a comprehensive exposition of the Transcendental Deduction of the Categories in both editions of Kant’s Critique of Pure Reason.

Dieter Henrich’s reconstruction of the transcendental deduction in "Identität und Objektivität" has been criticised (probably unfairly) by Guyer and others for assuming that we have a priori Cartesian certainty about our own continuing existence through time. In his later article "The Identity of the Subject in the Transcendental Deduction", Henrich addresses this criticism and proposes a new, again entirely original argument for a reconstruction. I attempt to elucidate this argument with reference to Evans’s theory of the (...) Generality Constraint and a remark of Strawson’s in Individuals. Its logical form of a sentence-operator requires that the "I think" be capable of accompanying every thought that we can form. Henrich seems to rely on this point, claiming in addition that we must be aware of this property of the "I think". I object that we cannot assume everyone to be capable of doing the philosophy of her own situation. (shrink)

To understand Kant's transcendental deduction of categories we must distinguish between Kant's strategy foe constructing such a deduction and the manner in which this strategy is executed. I argue that both versions of the deduction contain similar strategies in which categories are identified with transcendental conditions of experience. Where the versions differ substantially is in the manner Kant executes the various stages of this strategy. It is pointed out, for instance, that in the objective (...) class='Hi'>deduction in A Kant introduces 'understanding' as a defined term, whereas in B Kant postulates understanding as the fundamental activity of synthesis in terms of which he formulates the arguments of each stage of the deduction. Once the distinction between strategy and execution is accepted, much of Vaihinger's evidence for the "patchwork thesis" dissolves. But I also argue that in neither version of the deduction does Kant execute the identificatory strategy with convincing success. (shrink)

This is a monumental study of the transcendental deduction—that argument of legendary obscurity lying at the heart of Immanuel Kant’s Critique of Pure Reason. Allison begins from the methodological precept that “Kant’s argument can best be understood in light of the internal development of his thought”, and his book thus provides a systematic historical account of the deduction and its emergence from earlier texts. It begins with two chapters on the major pre-critical writings, which trace the emergence (...) of Kant’s “methodological” concerns with the limits and possibilities of metaphysical theorizing. However, this concern... (shrink)

In this paper, I aim to shed light on the use of transcendental deductions, within demonstrations of aspects of Wittgenstein's early semantics, metaphysics, and philosophy of mathematics. I focus on two crucial claims introduced by Wittgenstein within these transcendental deductions, each identified in conversation with Desmond Lee in 1930-31. Specifically, the claims are of the logical independence of elementary propositions, and that infinity is a number. I show how these two, crucial claims are both demonstrated and subsequently deployed (...) by Wittgenstein within a series of transcendental deductions, a series which begins with extensionalism as a generalized condition of sense on propositions, and in the context of which are then derived various, further, significant and unobvious presuppositions generated by that generalized condition of sense. In addition to clearing up deductions of these two, aforementioned claims, I also elucidate deductions of the subsistence of objects, and of logical space as an infinite totality. (shrink)

One recent trend in Kant scholarship has been to read Kant as undertaking a project in philosophical semantics, as opposed to, say, epistemology, or transcendental metaphysics. This trend has evolved almost concurrently with a debate in contemporary philosophy of mind about the nature of concepts and their content. Inferentialism is the view that the content of our concepts is essentially inferentially articulated, that is, that the content of a concept consists entirely, or in essential part, in the role that (...) that concept plays in a system of inferences. By contrast, relationalism is the view that this content is fixed by a mental or linguistic item's standing in a certain relation to its object. The historical picture of Kant and the contemporary debate about concepts intersect in so far as contemporary inferentialists about conceptual content often cite Immanuel Kant not only as one of the founding fathers of a tradition that leads more or less straightforwardly to contemporary inferentialism, but also as the philosopher who first saw the fatal flaws in any attempt to articulate the content of our concepts relationally.

The concept of political authority is the guiding problematic of Kant's mature political philosophy. The proper foundation of state authority lies, according to him, in the idea of an “original contract” and it is only in terms of this regulative principle that the sovereign nature of the state can even be conceived. By placing this doctrine at the core of his political thought Kant appears to affirm the fundamental tenet of the contractarian tradition: legitimate political authority arises only from the (...) consent of those under such authority.

The purpose of the third section of Kant’s Groundwork is to prove the possibility of the categorical imperative. In the end of the second section, Kant establishes that a proof like this is necessary to show that morality is ‘something’ and ‘not a chimerical idea without any truth’ or a ‘phantom’. Since the categorical imperative was established as a synthetic a priori practical proposition, in order to prove its possibility it is necessary ‘to go beyond cognition of objects to a (...) critique of the subject, that is, of pure practical reason’. Kant names this kind of proof a deduction. The present paper intends to show the argument whose purpose is to justify the categorical imperative; show that the argument is a transcendental deduction; present the argument as it is reconstructed by Allison, and show that, although it seems compelling, the position of the commentator could not be accepted by Kant himself.
