Kant: Truth

I provide in this paper an examination of the influence of Immanuel Kant on the internal realist Hilary Putnam. I begin by discussing Putnam’s transition from external, or metaphysical, realism to internal realism, and argue in favor of the view that Kant is best understood as an internal realist. Where Putnam is concerned, I am interested here only in his versions of external and internal realism and not with his more recent views. Having laid out a case for internal realism, (...) I go on to discuss and defend Putnam’s interpretation of Kant’s views on the nature of truth, arguing that although Kant accepts correspondence as a nominal definition of truth, he should not be understood as endorsing the metaphysical realist conception of truth. I conclude by arguing against those, including Ian Hacking and Allen Wood, who believe that the internal realist Putnam misinterpreted Kant on the nature of truth. This criticism rests on a misunderstanding of what Kant must have meant by ‘correspondence.’ Kant does not offer a theory of truth, but had he done so, his theory would be compatible with the internal realist Putnam’s. The view that their views on the nature of truth are incompatible is founded largely on misunderstanding of Kant, Putnam or both. (shrink)

One of the core issues where interpreters of Kant disagree is with regards to Kant’s alleged Noumenalism: the claim that the objects of our experience, which are in space and time, are underpinned by entities that are not spatio-temporal, and which non-spatio-temporally cause our representations of empirical objects. Although there is much textual evidence in favour of Noumenalism, non-Noumenalists have also gathered a significant number of philosophical and exegetical challenges to such a reading of Kant. I present a novel way (...) of understanding the Noumenalist view, which characterizes the distinction between appearances and things in themselves as the distinction between referents and truthmakers. After fleshing out this distinction, I show that, on this interpretation of Kant, the most pressing problems for the Noumenalist reading are primarily based on equivocations between features of reference and features of truthmaking.

A critical discussion of Lu-Adler's chapter on Kant's mature view of pure general logic. I sketch an alternative interpretation of its formality on which Kant would hold no deduction is possible of this logic's laws.

On the few occasions that Kant addresses the subject of truth, he usually does so in relation to the problems involved in the nominal definition of truth and in the search for a truth criterion. The aim of this paper is to provide a synoptic view of the way in which Kant poses these two issues. In the first section of the paper I address the topic of the definition of truth. I begin by explaining what a definition is and (...) what does this entail for the definition of truth. I then present the consequences and problems that Kant draws from this. In the second section of the paper I develop the topic of the criterion of truth. First, I set out Kant's expectations for such criterion and show the limits he encounters. Then I provide a classification and an explanation of the truth criteria that he mentions throughout his work. -/- En las pocas ocasiones en que Kant aborda el tema de la verdad, lo suele hacer en función de los problemas implicados en la definición nominal de verdad y en la búsqueda de un criterio de verdad. El objetivo de este trabajo es ofrecer una visión sinóptica del modo en que Kant plantea estas dos cuestiones. En la primera sección del trabajo se aborda el tema de la definición de la verdad. Primero explico qué es una definición y qué implica esto para el caso de la verdad. Tras esto, expongo las consecuencias y problemas que Kant extrae al respecto. En la segunda sección del trabajo se desarrolla el tema del criterio de verdad. Para comenzar expongo las expectativas de Kant respecto de dicho criterio y los límites con que se encuentra. Tras esto ofrezco una clasificación y explicación de los criterios de verdad que menciona a lo largo de su obra. (shrink)

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

This book is a masterpiece on Kant's theory of analyticity. It culminates in a new story of how Kant arrived at his mature view. Here is the chief lesson of this story: "the logical conception of the analytic/synthetic distinction is the fundamental idea of analyticity involved in Kant's distinctive, critical project. … [H]is critique of metaphysics crucially depends on the logical conception and cannot be supported by its merely methodological and epistemological ancestors". This passage consolidates two leading theses of the (...) book: Kant has three versions of the analytic/synthetic distinction: a methodological distinction between two ways of knowing, an epistemological one between two kinds of concept...

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

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)

ABSTRACTTaking its cue from Hannah Arendt’s comment that ‘truth gets lost in the Enlightenment’ and Lessing’s parable of God’s ‘left hand’, this paper traces a historical shift in moral and religious thought: roughly from truth to sincerity. From traditional conceptions of conscience as conditional on the objective truth of its content, the paper moves on, via the Reformation and seventeenth-century Augustinian turn, to early modern debates on toleration and the ‘erring conscience’. It is argued that Pierre Bayle’s Commentaire Philosophique of (...) 1686 can be read as a crucial catalogue for understanding the substitution of truth with sincerity : so that not truth but truthfulness is considered to be essential for moral and religious justification. Moving from Bayle to Immanuel Kant, the paper then shows how many of the same questions rise in Kant’s late essay on theodicy, which is also an essay on sincerity or integrity, via the Book of Job. Through these two thinkers, various themes are connected: from conscience and sincerity to the problem of the conscientious persecutor. Finally, these themes of truth, error and integrity are linked to the modern debate on authenticity, and a framework is proposed for conceptualising these various shifts. (shrink)

Kant is known for having said relatively little about truth in Critique of Pure Reason. Nevertheless, there are important lessons to be learned from this work about truth, lessons that apply to the contemporary debate on the nature and structure of truth and its theory. In this paper I suggest two such lessons. The first lesson concerns the structure of a substantive theory of truth as contrasted with a deflationist theory; the second concerns the structure of a correspondence theory of (...) truth. The first lesson warns us against conceiving of a substantive theory of truth in a way that led Kant to conclude that such a theory is unviable. In so doing it indirectly suggests what a viable substantive theory of truth would be like. The second lesson teaches us that a correspondence theory of truth need not be as naive and overly simplistic as it is usually thought to be, but can, and should be, far more complex. This lesson is based on a correspondence theory of truth incipient in the Critique, one whose structure reflects the complexity of the relation between mind and world in Kant’s theory. (shrink)

Kant's Notion of "Transcendental Truth". [English] The aim of this work is to elucidate the notion of “transcendental truth” and to show its role in the Kantian system. I will argue that this notion is in line with the traditional definition of truth, i.e., that it consists in the correspondence between knowledge and object. I will also argue that criteria of transcendental truth are provided by transcendental logic, and that it is this notion of truth what makes it possible to (...) establish the truth of a priori knowledge and delimitate the field of empirical truth. [Español] El objetivo de este trabajo es dilucidar la noción de “verdad trascendental” y mostrar su lugar en el sistema kantiano. Se defenderá que la verdad trascendental consiste, en línea con la definición tradicional de verdad, en un sentido de correspondencia entre conocimiento y objeto, que la lógica trascendental establece criterios de verdad trascendental, y que es esta noción de verdad la que permite establecer la verdad del conocimiento a priori y delimitar el territorio de la verdad empírica.

R. Lanier Anderson presents a new account of Kant's distinction between analytic and synthetic judgments, and provides it with a clear basis within traditional logic. He reconstructs compelling claims about the syntheticity of elementary mathematics, and re-animates Kant's arguments against traditional metaphysics in the Critique of Pure Reason.

Robert Hanna works out a unified contemporary Kantian theory of rational human cognition and knowledge. Along the way, he provides accounts of intentionality and its contents, sense perception and perceptual knowledge, the analytic-synthetic distinction, the nature of logic, and a priori truth and knowledge in mathematics, logic, and philosophy. This book is specifically intended to reach out to two very different audiences: contemporary analytic philosophers of mind and knowledge, and contemporary Kantian philosophers or Kant-scholars. At the same time, it rides (...) the crest of a wave of exciting and revolutionary emerging new trends and new work in the philosophy of mind and epistemology, with a special concentration on the philosophy of perception. What is revolutionary in this new wave are its strong emphases on action, on cognitive phenomenology, on disjunctivist direct realism, on embodiment, and on sense perception as a primitive and proto-rational capacity for cognizing the world. Hanna makes a fundamental contribution to this philosophical revolution by giving it a specifically contemporary Kantian twist, and by pushing these new lines of investigation radically further.

Kant identifies knowledge [Wissen], belief [Glaube], and opinion [Meinung] as our three primary modes of “holding-to-be-true” [Fürwahrhalten]. He also identifies opinion as making up the greatest part of our cognition. After a preliminary sketch of Kant’s system of propositional attitudes, this paper will explore what he says about the norms governing opinion and empirical hypotheses. The final section will turn to what, in the Critique of Pure Reason and elsewhere, Kant refers to as “General Applied Logic”. It concerns the “contingent (...) conditions of the subject, which can hinder or promote” good inquiry; and, though rarely mentioned in the secondary literature, it offers Kant’s methodological alternative to the traditional epistemological goal of finding “a sufficient and at the same time general criterion of truth”.

I defend the thesis that Kantian analytic judgments are about objects (as opposed to concepts) against two challenges raised by recent scholars. First, can it accommodate cases like “A two-sided polygon is two-sided”, where no object really falls under the subject-concept as Kant sees it? Second, is it compatible with Kant’s view that analytic judgments make no claims about objects in the world and that we can know them to be true without going beyond the given concepts? I address these (...) challenges in two steps. First, given Kant’s distinction between an object in general = x from an object of sensible intuition, I argue that analytic judgments are about objects in the former sense, no matter whether the purported objects can be given in our intuition. Second, using Kant’s method of representing certain logical relations of concepts with such figures as circles, I construct a model to show that analytic truths are truths about objects in general = x and yet can be determined solely by the intensional relation between the given concepts plus certain Kantian-logical laws. Analytic truths are thus shown as formal in the Kantian sense that they do not presuppose the purported objects as givable in our intuition. This account of the formality of analytic truths captures Kant’s diagnosis of the Leibnizian illusion that we can make material claims about the world by analytically true judgments. (shrink)

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

Many scholars claimed that, according to Immanuel Kant, some judgements lack a truth-value: analytic judgements, judgements about items of which humans cannot have experience, judgements of perception, and non-assertoric judgements. However, no one has undertaken an extensive examination of the textual evidence for those claims. Based on an analysis of Kant's texts, I argue that: (1) according to Kant, only judgements of perception are not truth-apt. All other judgements are truth-apt, including analytic judgements and judgements about items of which humans (...) cannot have experience. (2) Kant sometimes states that truth-apt judgements are actual bearers of truth or falsity only when they are taken to state what is actually the case. Kant calls these judgements assertoric. Other texts ascribe truth and falsity to judgements, regardless of whether they are assertoric. Kant's views on truth-aptness raise challenges for correspondentist and coherentist interpretations of Kant's theory of truth; they rule out the identification of Kant's crucial notion of objective validity with truth-aptness; and they imply that Kant was not a verificationist about truth or meaning. (shrink)

In this paper I argue that the Sellarsian Myth of the Given does not apply to all forms of Non-Conceptualism; that Kant is in fact a non-conceptualist of the right-thinking kind and not a Conceptualist, as most Kant-interpreters think; and that an intelligible and defensible Kantian Non-Conceptualism can be developed which supports the thesis that true perceptual beliefs are non-inferentially justified and also normatively funded by direct, embodied, intentional interactions with the manifest world (a.k.a. the Grip of the Given).

In the works of Kant and his followers, the notion of form plays an important role in explaining the apriority, necessity and certainty of logic. Bernard Bolzano (1781–1848), an important early critic of Kant, found the Kantians' definitions of form imprecise and their explanations of the special status of logic deeply unsatisfying. Proposing his own conception of form, Bolzano developed radically different views on logic, truth in virtue of form, and other matters. This essay presents Bolzano's views in the light (...) of his criticisms of the Kantian logicians. (shrink)

The result of Kant’s reflection on the traditional concept of truth as adequacy between knowledge or concept and object – the view that there is no general material or general formal criterion of truth which would be sufficient – leads towards the critical insight that we are regarding holding to be true, and that it presents itself in three modes: either as opinion, belief or knowledge. Therefore, not only Hegel, but Kant too came to realise that a proposition is not (...) “adequate” to “express” truth, but that a proposition – understood as an objectively valid relation which we formed – is what we hold to be true. What is striking and unsurpassably current in this finding is primarily the unique position and weight of knowledge which, according to Kant, also presents a mode of holding to be true, and not that kind – unattainable to a human – in which we the truth could be ensured without question. Thus, Kant's Critical philosophy is by no means no only met in the insight that existence cannot be expressed by a concept, but also in a no less fundamental insight that equally little can be inferred from the existence of concept.

This article proposes a reading of the Kantian transcendental apperception that attempts both to reinforce the cognitive efficacy of its spontaneity and to determine the modus operandi of its unifying function . Thus, being irreducible to a pure logical form , the I think is meant to constitute the qualitative unity of all possible representational system, insofar as it performs an infinite process of semantic or narrative unification. From this standpoint, the I think denotes the key operation that produces meaning, (...) and thereby the very possibility of truth. It follows, from such a framework of a procedural and constructivist theory of truth, the absolute primacy of the establishment of a semantic community by and under the Self. This community lays the foundation of coherence or organic cohesion of contents, and coherence provides the ground where correspondence emerges, which, in the last analysis, expresses nothing but the ever unfinished agreement of donation and action, agreement of Self with Itself.

The main point of disagreement about Kant's approach of the problem of truth is whether it can be understood within the apparatus of contemporary philosophy as a coherence or a correspondence theory. By favoring a systematic consideration of Kant's argumentation in light of the available literature on the problem, this paper argues toward the latter alternative. It is sustained that the definition of truth as "the agreement of cognition with its object" is cogent throughout Kant's thought and that it is (...) finally approached not from an established theory, but as a problem to which a solution cannot be given within the boundaries of the critical-transcendental philosophy. Initially, the literature which locates Kant either as coherentist or correspondentist is taken into account. The latter is systematized into four groups: the ontological reading; the isomorphic reading; the "consequentialist" reading; the regulative reading. Secondly, the argumentation in the pre-critical period is approached. It is argued that a coherence theory lacks its confirmation already within it and that in the decade of 1750 Kant disposes of the isomorphic correspondence reading. Finally, the critical argumentation is considered. It is sustained that the critical approach takes truth as a fundamental problem which cannot be held by a "consequencialist" or regulative correspondence theory.O principal ponto de desacordo sobre a abordagem kantiana do problema da verdade é se ela pode ser compreendida nos moldes da filosofia contemporânea como coerentista ou como correspondentista. Primando por uma consideração sistemática da argumentação de Kant em confronto com a literatura existente sobre o problema, este trabalho defende a segunda alternativa. Sustenta-se a tese de que a definição da verdade como a "concordância do conhecimento com o seu objeto" é cogente em todo o percurso do pensamento kantiano e que, nessa acepção, a verdade culmina por ser abordada não a partir de uma teoria estabelecida, mas como um problema cuja solução não pode ser dada nos limites da filosofia crítico-transcendental. Pondera-se, primeiramente, a literatura que situa Kant quer como coerentista quer como correspondentista e sistematiza-se a segunda alternativa em quatro grupos: a leitura ontológica, a leitura isomórfica, a leitura "consequencialista" e a leitura regulativa. Num segundo momento, em atenção ao período pré-crítico, argumenta-se que a alternativa coerentista deixa de se confirmar já nessa mesma época e que, na década de 1750, Kant descarta uma suposta teoria correspondentista isomórfica. Num último momento, considera-se a argumentação crítica e defende-se que a mesma concebe a verdade como um problema fundamental que não cabe ao tratamento de uma teoria correspondentista concebida de modo "consequencialista" ou regulativo.

Kant claims that the nominal definition of truth is: “Truth is the agreement of cognition with its object”. In this paper, I analyse the relevant features of Kant's theory of definition in order to explain the meaning of that claim and its consequences for the vexed question of whether Kant endorses or rejects a correspondence theory of truth. I conclude that Kant's claim implies neither that he holds, nor that he rejects, a correspondence theory of truth. Kant's claim is not (...) a generic way of setting aside a correspondence definition of truth, or of considering it uninformative. Being the nominal definition of truth, the formula “truth is the agreement of cognition with its object” illustrates the meaning of the predicate “is true” and people's ordinary conception of truth. True judgements correspond to the objects they are about. However, there could be more to the property of truth than correspondence. (shrink)

Kant's writings on logic illustrate the comparison argument about truth, which goes as follows. A truth-bearer p is true if and only if it corresponds, or it agrees, with a portion of reality: the object(s), state(s) of affairs, or event(s) p is about. In order to know whether p agrees with that portion of reality, one must check if that portion of reality is as p states. Using the terms of the comparison argument, one must compare p with that portion (...) of reality. This is impossible, because the only knowledge of reality we can have is in the form propositions, beliefs, or judgments, whose agreement with reality is as much in need of justification as the agreement of p with reality. Therefore, it is impossible to know which truth-bearers are true. This paper reconstructs Kant's version of the comparison argument. It is argued that, according to Kant, the argument is sound only under the assumption of transcendental realism. Transcendental idealism avoids the sceptical consequences of the comparison argument.

This paper argues that Kant's idea for a new kind of logic is bound up with a very specific strategy for obtaining truth criteria, where he takes Christian Wolff to have failed. While the First Critique 's argument against any universal criterion for empirical truth has almost always been treated as extraneous to the main concerns of the Transcendental Analytic, I argue that Kant inserted it at an important juncture in the text to illustrate a signal difference between traditional logics (...) and transcendental logic. Namely, while a criterion of truth as correspondence cannot be provided by traditional logics, since they cannot, in Kant's view, identify an object determinately and distinguish it from others, transcendental logic overcomes that particular barrier. The key to the improvement is to be found in how Kant modifies Wolffian order and “transcendental truth”, while still retaining them as central elements of his project. Once we have reconstructed Kant's strategy, we also gain a new perspective on Kant's puzzling assessments of his relation to Berkeley. (shrink)

In the Introduction to the Transcendental Dialectic, of the Critique of Pure Reason, Kant presents a conception of error. In the (Jäsche) Logic, he also deals with the problem of error, albeit in a different way. This paper aims to highlight this difference and arguing that, in the (Jäsche) Logic, error is explained more consistently and suitably than it is in the Transcendental Dialectic. It begins by considering judgment as the place of truth, falsehood and error, and inquiring into the (...) cognitive faculties that take part in its framing. These faculties, whose roles cannot be interchanged, are the sensibility, passive and receptive, and the understanding, active and spontaneous. Erroneous judgment springs from the unnoticed influence of sensibility on understanding, which makes the understanding hold merely subjective grounds of judgment to be objective ones. In the Transcendental Dialectic, this unnoticed influence is conceived in such a way that sensibility is, in a certain sense, held to be the determining ground of error, as if it were an active faculty, whereas in the (Jäsche) Logic that influence is conceived in such a way that the understanding itself is regarded as the source and author of error. This author agrees with the conception of the understanding as submitted to prescriptive laws, which is contained in the very definition of Pure General Logic, as a science of the a priori laws of how the understanding ought to think.

On the ground of Kant’s reformulation of the principle of con- tradiction, a non-classical logic KC and its extension KC+ are constructed. In KC and KC+, \neg(\phi \wedge \neg\phi),  \phi \rightarrow (\neg\phi \rightarrow \phi), and  \phi \vee \neg\phi are not valid due to specific changes in the meaning of connectives and quantifiers, although there is the explosion of derivable consequences from {\phi, ¬\phi} (the deduc- tion theorem lacking). KC and KC+ are interpreted as fragments of an S5-based first-order (...) modal logic M. The quantification in M is combined with a “subject abstraction” device, which excepts predicate letters from the scope of modal operators. Derivability is defined by an appropriate labelled tableau system rules. Informally, KC is mainly ontologically motivated (in contrast, for example, to Jaśkowski’s discussive logic), relativizing state of affairs with respect to conditions such as time. (shrink)

This paper argues that Kant, in his Critical period, did not have a coherence theory of truth. The paper outlines three coherence theories of truth and two coherence theories of empirical truth that Kant might have adopted. The three theories of truth are incompatible with Kant's texts. The two theories of empirical truth are compatible with the texts. However, there are no convincing reasons to hold that Kant adopted those theories.

Ernst Cassirer claimed that Kant's notion of actual object presupposes the notion of truth. Therefore, Kant cannot define truth as the correspondence of a judgement with an actual object. In this paper, I discuss the relations between Kant's notions of truth, object, and actuality. I argue that's notion of actual object does not presuppose the notion of truth. I conclude that Kant can define truth as the correspondence of a judgement with an actual object.

The classical view of the relationship between necessity and apriority, defended by Leibniz and Kant, is that all necessary truths are known a priori. The classical view is now almost universally rejected, ever since Saul Kripke and Hilary Putnam discovered that there are necessary truths that are known only a posteriori. However, in recent years a new debate has emerged over the epistemology of these necessary a posteriori truths. According to one view – call it the neo-classical view – knowledge (...) of a necessary truth always depends on at least one item of a priori knowledge. According to the rival view – call it the neoempiricist view – our knowledge of necessity is sometimes broadly empirical. In this paper I present and defend an argument against the neo-empiricist view. I argue that knowledge of the necessity of a necessary truth could not be broadly empirical. (shrink)

Attention to the conversational role of alethic terms seems to dominate, and even sometimes exhaust, many contemporary analyses of the nature of truth. Yet, because truth plays a role in judgment and assertion regardless of whether alethic terms are expressly used, such analyses cannot be comprehensive or fully adequate. A more general analysis of the nature of truth is therefore required – one which continues to explain the significance of truth independently of the role alethic terms play in discourse. We (...) undertake such an analysis in this paper; in particular, we start with certain elements from Kant and Frege, and develop a construct of truth as a normative modality of cognitive acts (e.g., thought, judgment, assertion). Using the various biconditional T-schemas to sanction the general passage from assertions to (equivalent) assertions of truth, we then suggest that an illocutionary analysis of truth can contribute to its locutionary analysis as well, including the analysis of diverse constructions involving alethic terms that have been largely overlooked in the philosophical literature. Finally, we briefly indicate the importance of distinguishing between alethic and epistemic modalities. (shrink)

This paper looks at the Kantian background in the development of the views on formal logic and contradiction in German Idealism. Assuming the post-Kantian view, I examine what Kant advanced and what he left unsettled, provoking thus the subsequent debate. I start by showing that already the pre-critical Kant questions the effectiveness of formal logic in philosophical discourse andclaims that the laws of identity and non-contradiction fall short of explaining change, opposition, and contradiction, all these being parts of reality. Turning (...) then to the first Critique, I discuss the introduction of transcendental logic as the logic of truth, consider how the tension between formal and transcendental logic is displayed in Kant’s exposition of the antinomy of pure reason, and arrive at the conclusion that Kant, despite his criticism, and unlike the other great German Idealists, allows formal logic to dominate his exposition of transcendental logic.

In this important new book, Douglas McDermid argues persuasively for two key claims: first, that the so-called "Neo-Pragmatist" critique of traditional epistemology is thoroughly unconvincing; second, that Rorty is guilty of taking the name of Pragmatism in vain, since there are crucial and far-reaching differences between Neo-Pragmatism and the Classical Pragmatism of James and Dewey. The Varieties of Pragmatism will take its place in the forefront of the literature on this most vital part of the American philosophical legacy.

Truth-telling is a project that is both gripping and problematic for Rousseau, as he is both captured by an ideal of telling as complete, undistorted discernment, documentation and communication, and also haunted by the fear that telling can never be this innocent. For Rousseau, as for Kant, telling does not leave the told untouched; rather, telling gives us a type of contact with objects that is marked and mediated by the process of telling itself, and hence the possibility of immediately (...) grasping objects through telling is forever lost to us. The drive to capture things in themselves, which originates, according to Kant, in a formal principle of reason, shows up in Rousseau's writings as a nostalgia that governs and animates inquiry. I will read Rousseau, and the traumas of truth-telling he articulates, as important pretexts for Kant's critical epistemology. Rousseau discloses tensions that infect his truth-telling practices. Kant seeks to neutralize these tensions, not by dissolving them, but rather by translating them into the terms of transcendental philosophy and thus showing how they can be defused and rendered harmless in their empirical form, so as to secure the possibility of proper truth-telling.

I. The Problem of ‘Truth’ in the Logic of Truth.

Originally presented as the author's thesis (doctoral - Halle-Wittenberg) under the title: Die Krise des theologischen Wahrheitsbegriffs.

This essay discusses Kant’s account of truth, arguing that he offers us a weak coherence theory: weak for his insistence on an independent, sensuous content for intuition, coherentist for the transcendental apparatus supporting experience. While Kant is free to use the language of correspondence within experience, “empirical truth” will always be limited by the formative requirements set by “transcendental truth.” The difficulty, for Kant, is the role played by sensuous content since the sameness of this content in intersubjective experience seems (...) to point outside the conditions of synthesis to a transcendentally real object. While the consequence of this would seem to leave Kant in a contradiction—denying transcendental realism at the same time that he must affirm it—we must read Kant’s insistence on a merely negative use of noumena as evidence that he adopts the role of the skeptic as a means for maintaining his epistemic goals.
