An anti-skeptical transcendental argument can be loosely defined as an argument that purports to show that some experience or knowledge of an external world is a necessary condition of our possession of some knowledge, concept, or cognitive ability that we know we have. In this dissertation I examine transcendental arguments by focusing on one such argument given by Immanuel Kant in his Critique of Pure Reason, along with some attempts to interpret that argument by contemporary commentators. ;I proceed by dividing (...) anti-skeptical transcendental arguments into three types: epistemological, verificationist, and psychological. I examine arguments of the first two types and show why they cannot succeed against the skeptic. I then argue that Kant's Refutation of Idealism is of a different type: it is psychological in that it concerns the necessary conditions of our forming beliefs of certain kinds. Many contemporary Kant scholars have claimed that his anti-skeptical strategy relies on phenomenalism or verificationism; I argue, however, that Kant in the Refutation employs a clever and hitherto unappreciated strategy which involves an empiricist principle concerning the origin of simple ideas, and which does not require either phenomenalism or verificationism. I conclude with an analysis and assessment of Kant's argument. (shrink)

Many commentators of Kant assume that the Refutation of Idealism is directed against a radical sceptic whose sole claim is immediate knowledge of his own representations in inner experience, including, to some extent, their temporal order. Accordingly, the Refutation is viewed as an attempt to establish that the perception of external objects is a prerequisite of knowing the temporal order of our representations. Here it will be argued that this minimal claim has to be supplemented by the (...) proposition that the idealist is aware of himself as a substance in time, if Kant’s Refutation is to be reconstructed as a successful argument. In addition, the view will be defended that the argument is not appropriate to decide the questio facti whether there are external objects or not. It rather establishes that the determination of the self as a substance in time is conceptually dependent on the perception of external objects. As a consequence, the argument does not preclude the possibility that some people are brains in a vat, as Q. Cassam justly remarked. (shrink)

This paper assesses the role of the Refutation of Idealism within the Critique of Pure Reason, as well as its relation to the treatment of idealism in the First Edition and to transcendental idealism more generally. It is argued that the Refutation is consistent with the Fourth Paralogism and that it can be considered as an extension of the Transcendental Deduction. While the Deduction, considered on its own, constitutes a 'regressive argument', the Refutation allows (...) us to turn the Transcendental Analytic into a 'progressive argument' that proceeds by the synthetic method. (shrink)

I will discuss Kant 's arguments in these section in three parts. In Part I, I will try to show how we can make sense of the obviously close relations in theme and content between the Refutation of Idealism and the two version of the Fourth Paralogism, as well as the second Postulate of Empirical Thought. This will serve as a kind of introduction, since on a cursory first reading, the connections might be far from apparent. In the (...) process, I will try to isolate a few basic. (shrink)

Recent developments of transcendental arguments reflect the struggle to accommodate Stroud’s devastating objection by giving up on failed expectations in providing proof of what the external-world skeptic calls into question: knowledge of the existence of the outside world. Since Strawson's capitulation in 1984, the truth-direct transcendental arguments have given way to modest belief-direct transcendental arguments that concede that truth-direct transcendental arguments are doomed to fail to establish ambitious conclusions about reality but at the same time hold that they can nonetheless (...) successfully establish modest conceptual connection between the major beliefs within our conceptual scheme. This article seeks the “reactionary” rehabilitation of the old hubris: a new defense of the truth-direct transcendental argument. I set forth a new reconstruction of Kant’s Refutation as a successful truth-directed transcendental argument that meets Stroud’s objection. As with several papers and books about the theme, this article is of a systematic and a historical nature by connecting the contemporary debate about transcendental argument with Kant’s philosophy.

The paper argues that in the Critique of Pure Reason Kant develops two anti-sceptical strategies. In the Fourth Paralogism (CPR A) he believes himself able to refute the sceptic by demonstrating that external perception is immediate. This strategy is rather unconvincing. In the Refutation of Idealism (CPR B) Kant promotes the material dependence of inner sense on outer sense. I show that Kant’s argument for material dependence has been widely overlooked, even though it is the strongest argument against (...) external world scepticism he develops, since it anticipates mental content externalism while preserving transcendental idealism and empirical realism. (shrink)

In this paper I shall show that Kant's best anti-sceptical argument, found in the “Refutation of Idealism” — hereafter Refutation —, is not successful in debunking the sceptic. My strategy will be to argue that, although dependent upon transcendental idealism, the Refutation is inconsistent with it. In order to achieve this goal, I shall sketch, in section 1, the two main interpretations of Kant's idealism, namely, the ‘two world’ and the ‘two aspect’ (...) theories. I shall maintain that the latter is more in keeping with Kant's overall intentions in the Critique of Pure Reason. In section 2, I shall spell out the main points of the Refutation. In section 3, I shall argue that, in the context of the Refutation, the conception of the permanent as the pre-condition of any temporal sequence clashes with some of the main doctrines of transcendental idealism. Finally, in section 4, I shall follow some unsuccessful attempts to harmonise transcendental idealism with the Refutation. (shrink)

Kant’s ‘Refutation of Idealism’ plainly has an anti-Cartesian conclusion: ‘inner experience in general is only possible through outer experience in general’ (B278). Due to wide-spread preoccupation with Cartesian skepticism, and to the anti-naturalism of early analytic philosophy, most of Kant’s recent commentators have sought to find a purely conceptual, ‘analytic’ argument in Kant’s Refutation of Idealism – and then have dismissed Kant when no such plausible argument can be reconstructed from his text. Kant’s argument supposedly cannot (...) eliminate all relevant alternatives, and so cannot justify its strong modal claims. Kant based his arguments on an inventory of our basic cognitive capacities to employ our forms of intuition and our forms of judgment. Kant provides a variety of considerations and arguments to determine what our cognitive capacities are. This involves ‘transcendental reflection’, which Kant held is absolutely crucial for judging matters a priori (A263/B319). I argue that there is a level of philosophical reflection on our own cognitive capabilities and their preconditions that is significantly richer than has been noticed by recent commentators, and that is a precondition of Kant’s transcendental reflection proper. I explicate certain thought experiments Kant proposes in order for us to recognize some our basic, characteristic cognitive capabilities, and the limits and requirements they entail for the nature and objects of human knowledge. These thought experiments involve a kind of reflection on who we as cognizant subjects are, on what our basic cognitive capabilities are. Engaging in this kind of reflection reveals that Kant’s transcendental arguments are significantly stronger and more persuasive than has been recognized in recent commentary. (shrink)

Among Immanuel Kant's most influential contributionsto philosophy is his development of the transcendental argument. InKant's conception, an argument of this kind begins with a compellingpremise about our thought, experience, or knowledge, and then reasonsto a conclusion that is a substantive and unobvious presupposition andnecessary condition of this premise. The crucial steps in thisreasoning are claims to the effect that a subconclusion or conclusionis a presupposition and necessary condition of a premise. Such anecessary condition might be a logically necessary condition, (...) butoften in Kant's transcendental arguments the condition is necessary inthe sense that it is the only possible explanation for the premise,whereupon the necessity might be weaker than logical. Typically, thisreasoning is intended to be a priori in some sense, eitherstrict or more relaxed. The conclusion of the argument is often directed againstskepticism of some sort. For example, Kant's Transcendental Deductiontargets Humean skepticism about the applicability of a priorimetaphysical concepts, and his Refutation of Idealism takes aim atskepticism about external objects. These two transcendental argumentsare found in the Critique of Pure Reason, butsuch arguments are found throughout Kant's works, for example inthe Critique of Practical Reason, in the Critiqueof the Power of Judgment, and in the OpusPosthumum. This article focuses on theTranscendental Deduction, the Refutation of Idealism, and more recenttranscendental arguments such as P. F. Strawson's that areinspired by these two examples. (shrink)

The dissertation analyzes Kant's arguments against Cartesian skepticism from the precritical period up to the "Reflexionen zum Idealismus" . It is argued that in the silent decade , the skeptical challenge leads Kant to reinterpret the foundation of his philosophy, namely, the distinction between appearances and things in themselves. Realizing the impossibility of refuting the skeptic through the identification of appearances with mental entities and the affirmation of the mind-independent existence of things in themselves as causes of the appearances (...) , Kant is forced to modify radically his notion of appearances in such a way as to make a new anti-skeptical argument possible. Thus, he no longer interprets appearances as mental entities, but as genuine, mind-independent objects. In this way, the skeptical challenge leads Kant to his mature notion of empirical realism, as presented in the 1781 Fourth Paralogism. ;The dissertation also shows that the mainstream evaluation of the arguments from the critical period needs to be revised. Some interpreters consider Kant's overall attempt to refute the skeptic ultimately unsatisfactory. Others are convinced that Kant manages to refute the skeptic only with the Second Edition argument, the Refutation of Idealism. The Fourth Paralogism---the argument that Kant presents in 1781, but drops in the Second Edition---is usually dismissed because of its alleged commitment to phenomenalism that makes it unable to serve as the foundation of the existence of a mind-independent world. In contrast with both groups, it is argued that Kant does have a powerful argument against the skeptic, which, however, is not to be found in the Refutation of Idealism or in its refinements in the "Reflexionen," but in a line of thought contained in the Fourth Paralogism, properly interpreted in a non-phenomenalistic way. The Refutation of Idealism, despite its intuitive appeal, ultimately fails and can be salvaged only if anti-skeptical resources are borrowed from the Fourth Paralogism. (shrink)

The verificationist defense of Kant's refutation of idealism is a specimen of the reconstructive work that needs to be done in evaluating Kant's transcendental philosophy. It is necessary to proceed piecemeal in the critical examination of each of Kant's arguments, fitting it to the proposed indirect proof model, and rethinking its soundness or unsoundness. There may be few conclusions that can stand just as they are. The justification of Kant's transcendental proof that there are (...) unknowable things in themselves establishes an important first step in this continuing inquiry. (shrink)

SummaryThis paper attempts to develop an interpretation of Kant's transcendental idealism which is based upon his critique of transcendental realism . It is argued that given Kant's transcendental distinction, all non‐ or pre‐critical philosophies, even Berkeleian phenomenalism are transcendentally realistic. This paradoxical result is used as the basis for an analysis of Kant's resolution of the mathematical antinomies, wherein this resolution is seen both as an “indirect proof” of transcendental idealism and as a refutation (...) of transcendental realism. Finally, it is claimed that Kant's idealism, at least insofar as it is established by means of a refutation of transcendental realism, is methodological rather than metaphysical, viz. it involves a claim about how the sensible world is to be considered in transcendental reflection, not a claim about the “real nature” of this world.RésuméCet article essaye de développer une interprétation de l'idéalisme transcendental de Kant, interprétation basée sur sa critique du réalisme transcendental .

This chapter analyzes two short texts in which Peirce sketches out an anti-skeptical argument inspired by Kant’s refutation of idealism. The chapter will first consider why Peirce found Kant’s argument interesting and promising, given that it is often regarded as problematic and unsuccessful. It will then briefly reconstruct Kant’s refutation, highlighting its most problematic passages. Moreover, since Peirce’s own version of the argument relies on Kant’s views regarding the temporal structure of consciousness, the chapter will explain how (...) Peirce tackles this issue in “The Law of Mind.” Finally, the chapter considers Peirce’s own anti-skeptical argument and examines whether and how it can be seen as appropriating Kant’s strategy.

Could each and every one of us, instead of interacting with actual objects, really be brains in a vat? In the first chapter of his new book, Reason, Truth and History, Professor Putnam raises this and related questions with the aim of undermining what he calls the “metaphysical realist” or “externalist” conception of reality. Putnam describes metaphysical realism as a view which holds that the world consists in “some fixed totality of mind-independent objects”; truth on this view amounts to a (...) correspondence between words or thoughts and these objects. Putnam contrasts metaphysical realism with a doctrine which he names “internalism” and calls on Kant to explicate its basic ideas. Putnam claims that Kant was the first philosopher to see clearly the difficulties inherent in metaphysical realism. The doctrine of transcendental idealism, says Putnam, represents Kant’s attempt to avoid externalism. But is Kant’s doctrine really just an early version of Putnam’s internalism? In this paper I shall argue that it is not. Although Kant obviously rejects the position Putnam calls “externalism,” I shall try to show that Kant’s metaphysical theory is distinct from internalism. Kant couples transcendental idealism with a second doctrine of empirical realism, and this enables Kant to circumvent both the internalist’s coherence theory of truth as well as a simple-minded correspondence theory. To be sure, one of Kant’s major concerns is to argue against the possibility of knowing things-in-themselves; Kant thus maintains, as Putnam correctly points out, that the nature of perceivers must figure in the nature of what is perceived. But this is not to say, as Putnam implies, that there is no mind-independent reality in Kant’s theory. On the contrary, Kant’s Refutation of Idealism—an argument that strikingly resembles the first horn of Putnam’s brain-in-a-vat dilemma—is designed to establish the existence of “matter,” which is Kant’s general term for what we might call the “external” or the “mind-independent.” Kant does argue that the perception of matter must accord with space and time, the two forms of sensibility, and this is the source of his transcendental idealism. But if we take this to mean that there cannot be anything independent of our minds or of our conceptual schemes, then we miss the point of Kant’s double doctrine of transcendental idealism and empirical realism, which is intended to avoid a coherence-only theory of truth while yet affirming that objects are knowable only as appearances. Putnam, by running together a number of Kantian notions, misrepresents Kant’s position and thus fails to see that Kant does offer an alternative to both metaphysical realism and internalism. I shall begin my defense of the claim that Kant does provide a third alternative by exploring more fully the debate between Putnam and the externalist concerning the BV dilemma. I shall then explore the Refutation of Idealism to support my claim that Putnam’s internalism is distinct from transcendental idealism. We shall see in section IV that in interpreting Kant on transcendental idealism Putnam makes two crucial mistakes which lead him to equate internalism with transcendental idealism. The result of these mistakes is discussed in section V. (shrink)

I reply to the most important criticisms made by Chignell of my ‘Kant's Refutation of Idealism’. I also introduce a new consideration which brings out more fully the power of Kant's argument.

This paper asks how Kant’s mature theory of freedom handles an objection pertaining to chance. This question is significant given that Kant raises this criticism against libertarianism in his early writings on freedom before coming to adopt a libertarian view of freedom in the Critical period. After motivating the problem of how Kant can hold that the free actions of human beings lack determining grounds while at the same maintain that these are not the result of ‘blind chance,’ I argue (...) that Kant’s Critical doctrine of transcendental idealism, while creating the conceptual space’ for libertarian freedom, is not intended to provide an answer to the problem of chance with respect to our free agency. I go on to show how the resources for a refutation of chance only come about in the practical philosophy. In the 2nd Critique, Kant famously argues for the reality of freedom on the basis of our consciousness of the moral law as the law of a free will. However, Kant also comes to build into his account of the will a genuine power of choice, which involves the capacity to deviate from the moral law. I conclude by showing that this apparent tension can be resolved by turning to his argument for the impossibility of a diabolical will. This involves a consideration of the distinct kind of grounding relationship that practical laws have to the human will, as well as the way that transcendental idealism makes this possible. (shrink)

This paper gives an interpretation of Kant's argument for transcendental idealism in the Transcendental Aesthetic. I argue against a common way of reading this argument, which sees Kant as arguing that substantive a priori claims about mind-independent reality would be unintelligible because we cannot explain the source of their justification. I argue that Kant's concern with how synthetic a priori propositions are possible is not a concern with the source of their justification, but with how they can (...) have objects. I argue that Kant's notion of intuition needs to be understood as a kind of representation which involves the presence to consciousness of the object it represents, and that this means that a priori intuition cannot present us with a mind-independent feature of reality.

In ‘Kant's Refutation of Idealism’ (Noûs, 47), I defend a version of the Refutation, pioneered by Paul Guyer inKant and the Claims of Knowledge, whose core idea is that the only way that one can know the order of one's own past experiences, except in certain rare cases, is by correlating them with the successive states of perceived external objects that caused the experiences. Andrew Chignell has offered a probing critique of my reconstruction of Kant's (...) argument (Philosophical Quarterly, 60), and I have responded (Philosophical Quarterly, 61). In a rebuttal of my response, Chignell raises three new objections (Philosophical Quarterly, 61). My purpose in this paper is to reply to these. (shrink)

Kant was never satisfied with the version of his “Refu- tation” published in 1787 (KrV, B 275-279). His dissatisfaction is already evident in the footnote added to the preface of the second edition of the Critique in 1787. As a matter of fact, Kant continued to rework his argument for at least six years after 1787. The main exegetical problem is to figure out who is the target of the “Refutation”: a non-skeptic idealist, a global skeptic of Cartesian provenance (...) or both. In this last case, the related problem is to know whether either of them is the Cartesian skeptic of the first Meditation, the idealist skeptic of the second Meditation and first part of the third Meditation, or some other non-skeptic idealist. I present and defend a new reconstruction of Kant’s “Refu- tation” as a successful argument against Mendelssohnian idealism of Cartesian provenance. This defense is based on a simple logical sketch of the proof provided by Dicker but essentially modified in light of Dyck’s insight about Kant’s opponent. How shall I support my reading? First, by appealing to overwhelming textual evidence according to which the proof is of the existence of mind-independent things, showing that Kant’s main opponent is Mendelssohn’s idealism of Cartesian provenance. Finally, I support my reading by showing that Kant’s “Refutation” is doomed to fail against all forms of global skepticism but is quite successful against Mendelssohn’s idealism. (shrink)

Immanuel Kant states that indirect arguments are not suitable for the purposes of transcendental philosophy. If he is correct, this affects contemporary versions of transcendental arguments which are often used as an indirect refutation of scepticism. I discuss two reasons for Kant’s rejection of indirect arguments. Firstly, Kant argues that we are prone to misapply the law of excluded middle in philosophical contexts. Secondly, Kant points out that indirect arguments lack some explanatory power. They can show that something is (...) true but they do not provide insight into why something is true. Using mathematical proofs as examples, I show that this is because indirect arguments are non-constructive. From a Kantian point of view, transcendental arguments need to be constructive in some way. In the last part of the paper, I briefly examine a comment made by P. F. Strawson. In my view, this comment also points toward a connection between transcendental and constructive reasoning.

Several of these essays--all but one-elucidate some aspect of Kant's new notion of "objectivity," that notion crucial to the transcendental foundation of universal and necessary knowledge intended to supersede the conflict of earlier "realisms" and "idealisms." And among these essays, all but one looks favorably upon Kant's effort. In the case of Moltke Gram's essay, a defense of Kant's refutations of idealism includes an argument for the consistency of the versions in the A and B editions (...) of the Critique, and a denial that the refutations require proofs of things in themselves; Kant succeeds in proving the existence of objects external to us. In the argument of the Fourth Paralogism, transcendentality is the key to the victory of objectivity: "If you say with Kant that all perceptual objects are transcendentally ideal, you are saying that perceptual objects which are spatial are as immediately available as mental objects", or that objects as causes of effects in our sensory apparatus are not merely inferred from their effects. Direct awareness of objects, albeit only phenomenal, distinguishes "empirical realism" from inference-making "empirical idealism". (shrink)

Kant’s Refutation targets what he calls the problematic idealist. This is understood by the mainstream of Kantian scholarship as the global skeptic that Descartes briefly adumbrated in his first Meditation. The widespread view in the literature is that the fate of the Refutation is tied to its success as an argument against this Cartesian global skepticism. This consensus is what I want to question in this paper. I argue that Kant’s opponent – the problematic idealist – is not (...) the Cartesian global skeptic but rather what I prefer to call here the Cartesian problematic external-world idealist. According to Cartesian global skepticism, we cannot know whether our commonsensical beliefs are true until we rule out that the skeptical hypotheses are false. In contrast, the Cartesian external-world idealist sees as problematic the assumption that the underlying nature of outer things of which we have ideas is mind-independent rather than caused by our own thinking. My aim here is to disentangle Cartesian global skepticism from Cartesian problematic external-word idealism and show that, if measured against global skepticism, Kant’s Refutation is doomed to fail, while against problematic idealism, it is at least a promising argument.

This paper provides a novel reconstruction of Kant’s argument for transcendental idealism in the Transcendental Aesthetic. This reconstruction relies on two main contentions: first, that Kant accepts the then-ubiquitous view that all cognition is either from grounds or consequences, a view he props up by drawing a distinction between logical and real grounds; second, that Kant, like most of his contemporaries, holds that our representations are the most immediate grounds of our cognition. By stressing these elements, the most threatening (...) objection to Kant’s argument can be avoided, namely, the claim that Kant ignores the possibility that our representations of space and time are subjective in origin, but objective as regards their applicability. My reconstruction shows that this so-called neglected alternative objection is based on a conceptual confusion about the nature of a priori cognition. (shrink)

The paper identifies a possible precedent for Kant’s Refutation of Idealism in the work of Johann Nicolaus Tetens. An attempt is made to reconstruct the reasoning that led Tetens to reject idealism as a false starting point, and some parallels are drawn between Tetens’s psychologistic approach to the problem andKant’s transcendental methodology.

In this invited book chapter I argue that, although the influence of Kant's transcendental idealism on the theories he puts forward in his book, Religion within the Bounds of Bare Reason (1793/1794) may not be apparent at first sight, careful attention to their structure reveals a deep influence. Indeed, understanding Kant's arguments in this book as an application of his transcendental idealism is crucial to a proper understanding of their structure and force.

Critical Idealism in the Eyes of Kant's Contemporaries BRIGITTE SASSEN THE IDEALISM DEBATES between Kant and his contemporaries were protracted and vehement. Interestingly, all parties in the debates -- Kant's critics, defend- ers, and Kant himself -- began with basically the same conception of idealism as a position that is either skeptical with regard to the inde- pendent existence of the external world , or that denies the existence of ma- terial substance outright .' Positions (...) quickly diverge, however, when it comes to transcendental idealism. Kant's crit- ics argued consistently that transcendental idealism reduces to material idealism. Kant rejected these arguments, insisting, in turn, that transcendental idealism is the only escape from material idealism. 2 Nonetheless, he was influenced by these criticisms. He repeatedly returns to the differentiation between transcendental and material idealism in the years following 17 81,3 and he casts these differences ' This is a paraphrase of the definition that appears in the introductory paragraph of the B- Refutation . Kant's contemporaries might not have bothered to make the differentiation between skeptical and dogmatic idealism, but they certainly agreed with the general terms in which Kant describes idealism. His definition is closely echoed by.. (shrink)

Kant's philosophy must be understood nonnaturalistically and anti-psychologistically. Self-consciousness must be interpreted as preceding the distinction between different persons. Kant departs from the traditional idea that I thoughts are always mediated by a certain specific I sense or conceptualization of oneself. At the same time the so-called paradoxes of self-consciousness are resolved. The possibility of a pre-personal self-consciousness is what links the way all objects are given to finite beings to the way they are conceptualized by those beings. It (...) serves as the unifying basis for intuitions and concepts. Intuitions and concepts of objects are connected by their relation to a numerically identical self. ;The subject construed impersonally provides the frame for any possible experience and is one in the same in all possible experience. As such it can never be experienced as a distinct entity. It is the condition under which it is possible to have a point of view at all. One must be in a position to become conscious of the numerical identity of this logical subject of all representation if is to be possible to communicate indeed to compare and contrast representational contents at all. ;Self-consciousness is inherently empty and yet also necessarily in relation to contents of consciousness. This means that its numerical identity can only be sustained if all potential contents of consciousness present themselves to the self in such a way that they sustain the possibility of consciousness of the self as having a discrete empirical identity. Kant's argument in the First Analogy and the Refutation of Idealism fulfills this demand for a correlate to the numerical identity of pre-personal consciousness in the data presented to self-consciousness spatio-temporally. We must view self-construction and construction of objects existing outside of us as part of a single process which presupposes an impersonal self-consciousness. (shrink)

Kant's monumental book the Critique of Pure Reason was arguably the most conceptually revolutionary work in the history of philosophy and its impact continues to be felt throughout philosophical debates today. However, it is a notoriously difficult work whose basic meaning and lasting philosophical significance are both subject to ongoing controversy. In this Critical Guide, an international team of leading Kant scholars addresses the challenges, clarifying Kant's basic terms and arguments and engaging with the debates that surround this (...) central text. Providing compact explanations along with cutting-edge interpretations of nearly all of the main themes and arguments in Kant's Critique, this volume provides well-balanced arguments on such controversial topics as the interpretation of Kant's transcendental idealism, conceptualism and non-conceptual content in perception, and the soundness of his transcendental arguments.

The article highlights the conceptual issues related to Kant’s analysis of the soul, a concept of utmost importance for the metaphysics and psychology of German academic philosophy (Schulphilosophie) of the Enlightenment was significantly dependent on the developed and systematically presented philosophical and scientific ideas and concepts of Christian Wolff. Kantian philosophy, its themes, and conceptual language were formed in the crucible of Wolfean discourse, and from the early 1770s in the struggle against it, which led to the emergence of a (...) new, critical philosophy – transcendental idealism, in which the problem of the soul, consciousness, and self-awareness became fundamental. It is this issue that was thoroughly covered in the «Critique of Pure Reason» and other works that were published later, after the first Critique. The article draws attention to Kant’s Lectures, which, on the one hand, demonstrate his critical attitude towards the so-called Wolfians, their metaphysics, and psychology, and, on the other hand, the lecture materials illustrate Kant's new conceptual position, and, what is important, develop, supplement and clarify it. The sources of Kant’s lectures are highlighted, taking into account the fact that we have at our disposal lecture notes, the authors of which are either unknown or, if known, their authorship is still somewhat doubtful, since they are notes that different people have rewritten. The article analyses lecture notes on psychology, the authors of which are more or less well-known, and experts recognize these notes as quite valid. The conceptual content of these lectures allows us to look at Kant’s understanding of the problem of the soul in a somewhat broader context compared to the «Critique of Pure Reason», where this problem is analyzed in connection with the paralogisms of reason and the transcendental deduction of categories. In his lectures on psychology, Kant draws attention to the problem of the interaction of the soul with the human body, the «location of the soul», linking it not so much to the organs of the human body (for example, the head) as to the location of a person as a bodily being in the world makes all acts of consciousness, self-awareness, and sense perception possible. Kant emphasizes the basic importance of such a spatial location of a person for the soul, as something that belongs to a person with a certain integrity, and not a separate organ, to act properly, to perform its cognitive functions. The article analyses the problem of existence, which is important for critical philosophy, its various modalities, and predication, with a special emphasis on the problem of the existence of metaphysical objects - the soul, God, and the world as a whole.

The aim of this paper has been to present a new reconstruction of Kant’s Refutation of Idealism. I have considered several different targets of the Refutation, five of them mentioned by Kant himself. I believe that I have shown that the Refutation of Idealism is best considered only as a sound argument against Mendelssohnian subjectivist idealism, against Mendelssohnian immaterialism, and against Mendelssohnian realist idealism. First, Kant’s Refutation is a sound argument in favor (...) of the claim that the outer things represented in our minds are real rather than ideal; that is, they exist mind-independently as noumena. And second, Kant’s refutation is a sound argument for a fundamental ontology of noumena: the ultimate nature of reality and of our minds is neither material nor mental but made up of things in themselves.

This paper argues that the Refutation of Idealism is a clear development of a line of thought expressed in the Transcendental Deduction and the Fourth Paralogism in the 1781-edition of the Critique of Pure Reason. This general line of thought is that the possibility of systematic delusion about the nature of the empirical world is ruled out, in part, by the fact that illusion presupposes a background of veridical perception.

Kant seems to think of our own mental states or representations as the primary objects of inner sense. But does he think that these states also inhere in something? And, if so, is that something an empirical substance that is also cognized in inner sense? This chapter provides textual and philosophical grounds for thinking that, although Kant may agree with Hume that the self is not ‘given’ in inner sense exactly, he does think of the self as cognized through inner (...) sense. It is also argued that he both does and ought to regard this self as an empirical substance in which our changing representations inhere. In the second part of the chapter it is suggested that this poses a significant problem for most of the leading interpretations of Kant’s anti-sceptical argument in the Refutation of Idealism.

In lieu of an abstract, here is a brief excerpt of the content:Kant's Critique of Berkeley HENRY E. ALLISON THE CLAIMTHAT KANT'S IDEALISM,or at least certain strands of it, is essentially identical to that of Berkeley has a long and distinguished history. It was first voiced by several of Kant's contemporaries such as Mendelssohn, Herder, Hamann, Pistorius and Eberhard who attacked the alleged subjectivism of the Critique of Pure Reason. 1 This viewpoint found its sharpest contemporary (...) expression in the notorious Garve-Feder review to which Kant responded at length in the Prolegomena. In subsequent times it has been championed by Schopenhauer, and most nineteenth century German commentators on the relation between the two philosophers. 2 In addition, it has been, and continues to be, the prevailing view of the vast majority of British writers on Kant, including, with significant qualifications, Norman Kemp Smith. 3 This tradition continues despite the fact that Kant specifically, and in no uncertain terms, repudiated this identification in the Prolegomena and the second edition of the Critique. In both works he responds to the charges of subjectivism, and in so doing distinguishes his position from that of Berkeley, who in the eighteenth century was commonly regarded as a solipsist and denier of the "external world." 4 In contra-distinction to Kant's own critical or transcendental idealism, which explains the possibility of synthetic a priori knowledge within the realm of possible experience, Berkeley is characterized as a "dogmatic" or "visionary idealist." He is judged guilty of "degrading bodies to mere illusion" (B69), of regarding things in space as "merely imaginary entities" (B274), and of holding with all "genuine idealists" that: "all knowledge through the senses and experience is i Cf. Hans Vaihinger, Commentar zu Kant's Kritik der Reinen Vernunft (Stuttgart, Berlin, Leipzig, 1892), II, 494-505. Cf. Friederich Fredericks, Der Phainomenale Idealisraus Berkeley's und Kant's (Berlin, 1871); Robert Zimmerman, "Ober Kant's Widerlegung des Idealismus yon Berkeley" (Sitzungsberichte der Akademie der Wissenschaften, Vienna, Philox.-hist. Kl.), LXVIII (1871); Gustav Dieckert, tiber dos Verhiiltnis des Berkeleyschen ldealismus zu Kantischen Vernun]tkritik (Konitz, 1888). Tiffs is a consequence of the general British tendency to view Kant in phenomenalist terms. A typical recent example is found in P. F. Strawson, The Bounds of Sense (London, 1966). Kemp Smith in his Commentary to Kant's Critique o[ Pure Reason (2nd ed., rev., 1923) takes greaZ pains to distinguish between the subjectivist strand in Kant's thought, which is essentially identical to Berkeley's position, and the genuine critical doctrine which stands side by side with it in the text. 9 Cf.

They are usually dismissed as obvious misinterpretations, due to Kant's ignorance of Berkeley's actual writings, and of his reliance upon distorted second and third hand accounts of Berkeley's thought such as is to be found in Beattie. Furthermore, this view is often supported by the philological reflection that Kant did not read English, and that Berkeley's writings were not yet available in German translation. 6 The philological argument, however, loses much of its force when we consider that there was indeed a German translation of Berkeley's Dialogues, which although apparently unknown to nineteenth century scholars, was readily accessible to Kant. This is to be found, together with a translation of Collier's Clavis Universalis and critical analyses, in a work by the professor of philosophy at Rostock, Johann Christian Eschenbach, entitled: Samlung der vornehmsten Schri[tsteller die die tFirklichkeit ihres eignen K~rpers und der ganzen Ki~rperwelt leugnen (Rostock, 1756). Furthermore, in addition to this work, which was probably known to Kant, there is Berkeley's important Latin work, De Motu (1721), as well as French translations of many of... (shrink)

This article offers the first systematic investigation of the linguistic forms in which Kant expresses his transcendental idealism since Gerold Prauss’ seminal book Kant und das Problem der Dinge an sich. It is argued that Prauss’ own argument for the claim that ‘in itself’ is an adverbial expression that standardly modifies verbs of philosophical reflection is flawed and that there is hence very poor exegetical evidence for so-called ‘methodological two-aspect’ interpretations of Kant’s transcendental idealism. A comprehensive investigation of (...) Kant’s adverbial uses of ‘in itself’ rather reveals that there are various groups of verbs that ‘in itself’ modifies, which can more or less all be reduced to a standard use in which ‘in itself’ modifies verbs of predicative being such as the copula. It is also discussed how these findings can be accommodated by the two main alternative kinds of interpretations, that is, two-object and ontological two-aspect interpretations. (shrink)

In the Transcendental Aesthetic (TA), Kant is typically held to make negative assertations about “things in themselves,” namely that they are not spatial or temporal. These negative assertions stand behind the “neglected alternative” problem for Kant’s transcendental idealism. According to this problem, Kant may be entitled to assert that spatio-temporality is a subjective element of our cognition, but he cannot rule out that it may also be a feature of the objective world. In this paper, I show in a (...) new way how Kant’s view (focusing on his conclusions about space) is not subject to this objection, by showing that he does not make the denial about mind-independent reality that he is typically held to make. The argument develops consequences of a new reading of Kant’s expression “an sich selbst” (‘in itself’; ‘in themselves’). I argue that “an sich selbst” or “per se” has a special, judgment-level role, so that this expression does not form new noun-terms adjectivally. It follows that the conceptual unit of Kant’s “Conclusions” in the TA is simply “things” (Dinge), since “things in themselves” is not a nominal expression; Kant adopts the Wolffian ontological use of “thing” as the basic kind-term for any existent. The arguments that things per se are not in space are arguments that space cannot be a necessary property or relations of things as a kind. I show that this does not involve the positive claim about mind-independent reality that inspires the neglected alternative objection. (shrink)

This book argues that Kant's transcendental idealism has been misinterpreted: it denies not simply the super-sensory reality of space, time, and appearances, but their reality outside imagination as well. After adducing extensive and explicit textual evidence in its favor, Waxman shows this interpretation to be essential to the Transcendental Deduction, the affirmation of things in themselves, and the attempt to surmount Hume's scepticism. He further argues that Kant's much-neglected claim that, besides himself, "no psychologist has so much (...) as even thought that the imagination might be a necessary constituent of perception," should be construed so that even our consciousness of sensation itself (visual, tactile, etc.) is impossible without imagination. A compelling and original contribution to Kantian scholarship, Kant's Model of the Mind will also bear close examination by students and scholars of Hume, the philosophy of mind, and the philosophy of science.

In the Refutation of Idealism, Kant aims to defeat the Cartesian radical skeptical hypothesis that empirical reality might not exist and we cannot have knowledge of it. Kant intends to demonstrate that conscious experience presupposes direct experience of empirical reality. This paper presents new challenges to the conclusions Kant reaches in the Refutation. Kant’s argument turns on the claim that the past must exist, and my challenges concern the possibility that there is no past.

In what follows I will address Kant’s concerns in the First Analogy and in the Refutation of Idealism. Because the two discussions have a similar trajectory, it is of interest to identify some of the differences between them. As we will see, the manifest differences are indicative of more significant underlying differences, regarding two ways of construing transcendental proofs.

What is the highest good actually good for in Kant’s third Critique? While there are well-worked out answers to this question in the literature that focus on the highest good’s practical importance, this paper argues that there is an important function for the highest good that has to do exclusively with contemplation. This important function becomes clear once one notices that coherent [konsequent] thinking, for Kant, was synonymous with "bündiges" thinking, and that both are connected with the highest good in (...) the third Critique’s moral proof for God’s existence. I show that the original meaning of "bündig," which is from the carpentry trade and has been forgotten, illuminates the stakes of the highest good in Kant’s system. For us, as proverbial carpenters of reason, coherence is essential for the intellectual activity of constructing a philosophical worldview in his transcendental idealism. I motivate the reading further by showing how this function can neatly reconstruct Kant’s proof for God’s existence in the third Critique. I conclude by sketching Kant’s reasons for why the project of creating a coherent worldview grounded in the highest good is worth the labor costs. (shrink)

Kant’s Refutation targets what he calls the problematic idealist. This is understood by the mainstream of Kantian scholarship as the global skeptic that Descartes briefly adumbrated in his first Meditation. The widespread view in the literature is that the fate of the Refutation is tied to its success as an argument against this Cartesian global skepticism. This consensus is what I want to question in this paper. I argue that Kant’s opponent – the problematic idealist – is not (...) the Cartesian global skeptic, but rather what I prefer to call here the Cartesian problematic external-world idealist. According to Cartesian global skepticism we cannot know whether our commonsensical beliefs are true until we rule out the skeptical hypotheses are false. In contrast, the Cartesian external-world idealist sees as problematic the assumption that the underlying nature of outer things of which we have ideas is mind-independent rather than caused by our own thinking being. My aim here is to disentangle Cartesian global skepticism from Cartesian problematic external-word idealism and show that, if measured against global skepticism, Kant’s Refutation is doomed to fail; while against problematic idealism, it is at least a promising argument.

It is argued that there is a plausible way to read Kant as consistently repudiating a two-worlds picture and upholding a de-reistic view whereby the transcendental object or thing in itself indicates only a pure concept of the understanding whose role is to govern the synthesis of any unified manifold. This reading of Kant liberates him from the well-known textual and philosophical difficulties of the two-worlds view. Furthermore, I argue that this interpretation leads to a strong idealist position as opposed (...) to the double-aspect view of Allison and Prauss. This idealist position was basically adopted by Fichte in his Introductions to the Science of Knowledge of 1797, wherein the debunking of the thing in itself was a crucial step in his ultimate argument for the unity of theoretical and practical reason.

A concept of the ‘actual now’ is introduced. The ‘actual now’ is negatively characterized by the fact that it is absent from the time-series. This does not mean that the ‘actual now’ is outside the time-series. For saying so would wrongly suggest the existence of an ‘outside’ where the ‘actual now’ could be located. Instead, one considers that the ‘actual now’ is just the name of ‘that with respect to which’ any event can be said to be past or future, (...) yet being no event by itself. It holds the same role with respect to time as Husserl’s transcendental ego with respect to the empirical self. McTaggart’s celebrated refutation of the reality of time is reinterpreted accordingly. To express this argument, one no longer needs to use the notions of ‘change’ or ‘time flow’, but only to point out the in-principle impossibility to refer to the ‘actual now’. (shrink)

The central question of this paper is: what has Kant’s Refutation of Idealism argument proven, if anything? What is the real scandal of philosophy and universal human reason? I argue that Kant’s Refutation argument can only be considered sound if we assume that his target is what I call ‘metaphysical external-world skepticism.’ What is in question is not the ‘existence’ of outside things but their very ‘nature,’ that is, the claim that the thing outside us, which appears (...) to us as a persistent body in space, exists in itself _as a substantia noumenon_. Assuming the indirect-realist view that we only immediately know ideas and that their putative objects are known by inference, the metaphysical external-world skeptic doubts that the nature of things outside oneself is mind-independent.

Kant’s criticism of Metaphysics is informed by his reception of Hume’s skepticism. While the claims of the synthetic a priori, for Kant, constitute a transcendental refutation of Hume’s skepticism, Kant remains in fundamental sympathy with Hume’s empiricism. On the one hand he invokes the synthetic a priori in limiting the unbridled empiricism that conflates the distinction between sources of knowledge and origin of knowledge. On the other hand he also underscores the inherent limitation of human knowledge as legislated by (...) the same empirical ideal, so that in the final analysis there is a fundamental tension in the critical philosophy with respect to Kant’s commitment to idealism and empiricism.
