Racist beliefs express value judgments. According to an influential view, value judgments are subjective, and not amenable to rational adjudication. In contrast, we argue that the value judgments expressed in, for example, racist beliefs, are false and objectively so. Our account combines a naturalized, philosophical account of meaning inspired by Donald Davidson, with a prominent social-psychological theory of values pioneered by the social-psychologist Milton Rokeach. We use this interdisciplinary approach to show that, just as (...) with beliefs expressing descriptive judgments, beliefs expressing value judgments have empirical content, or can be inferentially linked to beliefs that do; the truth or falsity of that content can be objectively assigned; and that assignment is amenable to rational assessment. While versions of this objective view of value judgments have been defended by moral realists of various metaphysical stripes, our argument has the virtue of appealing, instead, to accounts that are as naturalistically informed as possible. And, unlike the influential subjective view of value judgments, and racist beliefs more particularly, our arguments are better able to account for instances where rational, persuasive strategies have been effective in reducing the ubiquity of racism in American culture.

Recent experimental work has shown that the truth-value judgments of color predications, i.e. utterances of the form “the leaves on my tree are green” or “these walls are brown,” are influenced by slight changes in the context of utterance (Hansen and Chemla 2013, Ziółkowski, 2021). Most explanations of this phenomenon focus on the semantics of color adjectives. However, it is not clear if these explanations do justice to the nuances of the empirical data on context-sensitivity of color (...) predications (Ziółkowski, 2021). In contrast to the adjectival explanations, Agustin Vicente (2015) has recently proposed that the context-sensitivity of color predications can be explained by invoking the polysemy of the noun. In this paper, we present the results of three studies designed to empirically test this hypothesis: a traditional survey experiment (Study 1), an exploratory correlational study inspired by the semantic integration paradigm (Study 2a), and a follow-up experiment (Study 2b) that was designed to mitigate possible shortcomings of Study 2a. The results of our studies present preliminary evidence against Vicente’s theory. (shrink)

Roman Suszko said that “Obviously, any multiplication of logical values is a mad idea and, in fact, Łukasiewicz did not actualize it.” The aim of the present paper is to qualify this ‘obvious’ statement through a number of logical and philosophical writings by Professor Jan Woleński, all focusing on the nature of truth-values and their multiple uses in philosophy. It results in a reconstruction of such an abstract object, doing justice to what Suszko held a ‘mad’ project within a (...) generalized logic of judgments. Four main issues raised by Woleński will be considered to test the insightfulness of such generalized truth-values, namely: the principle of bivalence, the logic of scepticism, the coherence theory of truth, and nothingness.

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.

The past decade has seen a protracted debate over the semantics of epistemic modals. According to contextualists, epistemic modals quantify over the possibilities compatible with some contextually determined group’s information. Relativists often object that contextualism fails to do justice to the way we assess utterances containing epistemic modals for truth or falsity. However, recent empirical work seems to cast doubt on the relativist’s claim, suggesting that ordinary speakers’ judgments about epistemic modals are more closely in line with contextualism (...) than relativism (Knobe & Yalcin 2014; Khoo 2015). This paper furthers the debate by reporting new empirical research revealing a previously overlooked dimension of speakers’ truth-value judgments concerning epistemic modals. Our results show that these judgments vary systematically with the question under discussion in the conversational context in which the utterance is being assessed. We argue that this ‘QUD effect’ is difficult to explain if contextualism is true, but is readily explained by a suitably flexible form of relativism. (shrink)

In this paper I draw on some of the work of John McDowell in order to develop a realist account of normative reasons for action. On the view defended here, there can be correct moral judgments that capture the reasons there are for acting in certain ways; and the reasons themselves are just some of the morally relevant facts of the situation about which the judgment is made. Establishing this account relies crucially, I argue, on an appeal to substantive (...) ethical theory, to a theory that allows for the attribution of truth to the judgments in question. The account defended here can in fact be equally well supported by ethical theories as otherwise diverse as those of Aristotle and Kant. The resulting account is a version of moral realism, but one that is not committed to defending a realist account of the nature of moral value. (shrink)

Kuhn's alleged taxonomic interpretation of incommensurability is grounded on an ill defined notion of untranslatability and is hence radically incomplete. To supplement it, I reconstruct Kuhn's taxonomic interpretation on the basis of a logical-semantic theory of taxonomy, a semantic theory of truth-value, and a truth-value conditional theory of cross-language communication. According to the reconstruction, two scientific languages are incommensurable when core sentences of one language, which have truth values when considered within its own context, lack (...) truth values when considered within the context of the other due to the unmatchable taxonomic structures underlying them. So constructed, Kuhn's mature interpretation of incommensurability does not depend upon the notion of truth-preserving translatability, but rather depends on the notion of truth-value-status-preserving cross-language communication. The reconstruction makes Kuhn's notion of incommensurability a well grounded, tenable and integrated notion.Author Keywords: Incommensurability; Thomas Kuhn; Taxonomic structures; Lexicons; Truth-value; Untranslatability; Cross-language communication.

There is strong disagreement about whether indicative conditionals have truth values. In this paper, I present a new argument for the conclusion that indicative conditionals have truth values based on the claim that some true statements entail indicative conditionals. I then address four arguments that conclude that indicative conditionals lack truth values, showing them to be inadequate. Finally, I present further benefits to having a worldly view of conditionals, which supports the assignment of truth values to (...) indicative conditionals. I conclude that certain types of account of indicative conditionals, which have been ignored in the literature partly on the basis of assigning truth values to indicative conditionals, deserve consideration.

According to the accepted translation-failure interpretation, the problem of incommensurability involves the nature of the meaning-referential relation between scientific languages. The incommensurability thesis is that some competing scientific languages are mutually untranslatable due to the radical variance of meaning or/and reference of the terms they employ. I argue that this interpretation faces many difficulties and cannot give us a tenable, coherent, and integrated notion of incommensurability. It has to be rejected. ;On the basis of two case studies, I find that (...) the confrontations between many classical incommensurable languages are not confrontations between two untranslatable languages with different distribution of truth values, but rather the confrontations between incompatible fundamental presuppositions at the ontological level. We can always identify a truth-value gap between two incommensurable languages. Such a truth-value gap indicates a communication breakdown between the two language communities on the one hand, and is caused by the incompatible fundamental presuppositions underlying them on the other. ;I thereby identify the truth-value functional relationship between sentences, instead of the meaning-referential relationship between terms, as the dominant semantic relation between two incommensurable languages. According to my presuppositional interpretation of incommensurability, the real secret of incommensurability lies in the ontological setup of two competing presuppositional languages. When two presuppositional languages with incompatible factual commitments encounter with each other, the confrontation leads to a truth-value gap, and consequently a communication breakdown between them. Formally put, two scientific languages are incommensurable when core sentences of one language, which have truth values when considered within its own context, lack truth values when considered within the context of the other due to an ontological gap between them. ;The presuppositional interpretation makes many significant contributions to the discussion of the issue of incommensurability and the related metaphysical and epistemological issues: It confirms the existence of the phenomenon of incommensurability and makes it metaphysically and epistemologically significant. It establishes the tenability and integrity of the notion of incommensurability. It avoids many alleged unattractive epistemological and metaphysical consequences of the translation-failure interpretation. (shrink)

I aim to offer a practical response to skepticism. I begin by surveying a family of responses to skepticism that I term “dogmatic” and argue that they are problematically evasive; they do not address what I take to be a question that is central to many skeptics: Why am I justified in maintaining some beliefs that fail to meet ordinary standards of doxastic evaluation? I then turn to a discussion of these standards of evaluation and to the different kinds of (...) doxastic value to which they appeal. While there is something good about having a true belief and something bad about having a false one, I argue the value of true beliefs is not intrinsic or final. Truth and knowledge are valuable because they contribute to both individual and collective flourishing. But if contributing to flourishing is what ultimately provides truth with its value, then we have discovered another doxastic value. I call this kind of doxastic value “practical.” The practical response addresses the skeptic’s question by claiming that some beliefs can be justified by appealing to their practical, rather than alethic, value. In fleshing out this practical response I contrast it both with dogmatic responses as well as some seemingly similar “practical” alternatives, namely Crispin Wright’s appeals to entitlements and Susanna Rinard’s “pragmatic skepticism.” I end by addressing some objections.

ABSTRACT: In its strongest unqualified form, the principle of wholistic reference is that in any given discourse, each proposition refers to the whole universe of that discourse, regardless of how limited the referents of its non-logical or content terms. According to this principle every proposition of number theory, even an equation such as "5 + 7 = 12", refers not only to the individual numbers that it happens to mention but to the whole universe of numbers. This principle, its history, (...) and its relevance to some of Oswaldo Chateaubriand's work are discussed in my 2004 paper "The Principle of Wholistic Reference" in Essays on Chateaubriand's "Logical Forms". In Chateaubriand's réplica (reply), which is printed with my paper, he raised several important additional issues including the three I focus on in this tréplica (reply to his reply): truth-values, universes of discourse, and formal ontology. This paper is self-contained: it is not necessary to have read the above-mentioned works. The principle of wholistic reference (PWR) was first put forth by George Boole in 1847 when he espoused a monistic fixed-universe viewpoint similar to the one Frege and Russell espoused throughout their careers. Later, Boole elaborated PWR in 1854 from the pluralistic multiple-universes perspective. (shrink)

Donkey sentences have existential and universal readings, but they are not often perceived as ambiguous. We extend the pragmatic theory of nonmaximality in plural definites by Križ (2016) to explain how context disambiguates donkey sentences. We propose that the denotations of such sentences produce truth-value gaps — in certain scenarios the sentences are neither true nor false — and demonstrate that Križ’s pragmatic theory fills these gaps to generate the standard judgments of the literature. Building on Muskens’s (...) (1996) Compositional Discourse Representation Theory and on ideas from supervaluation semantics, the semantic analysis defines a general schema for quantification that delivers the required truth-value gaps. Given the independently motivated pragmatic theory of Križ 2016, we argue that mixed readings of donkey sentences require neither plural information states, contra Brasoveanu 2008, 2010, nor error states, contra Champollion 2016, nor singular donkey pronouns with plural referents, contra Krifka 1996, Yoon 1996. We also show that the pragmatic account improves over alternatives like Kanazawa 1994 that attribute the readings of donkey sentences to the monotonicity properties of the embedding quantifier.

Confused terms appear to signify more than one entity. Carnap maintained that any putative name that is associated with more than one object in a relevant universe of discourse fails to be a genuine name. Although many philosophers have agreed with Carnap, they have not always agreed among themselves about the truth-values of atomic sentences containing such terms. Some hold that such atomic sentences are always false, and others claim they are always truth-valueless. Field maintained that confused terms (...) can still refer, albeit partially, and offered a supervaluational account of their semantic properties on which some atomic sentences with confused terms can be true. After outlining many of the most important theoretical considerations for and against various semantic theories for such terms, we report the results of a study designed to investigate which of these accounts best accords with the truth-value judgments of ordinary language users about sentences containing these terms. We found that naïve participants view confused names as capable of successfully referring to one or more objects. Thus, semantic theories that judge them to involve total reference failure do not comport well with patterns of ordinary usage. (shrink)

A primary challenge from the relativist to the contextualist about epistemic modals is to explain eavesdropping data—i.e., why the eavesdropper is inclined to judge the speaker as having uttered an epistemic modal falsehood (when she is so inclined), even though the speaker’s utterance is true according to reasonable contextualist truth conditions. The issue turns in large part on the strength and shape of the data, both of which are in dispute. One complaint is that an eavesdropper’s truth (...) class='Hi'>value judgments fluctuate with variations of non- epistemic fact (even after the relevant epistemic/information states are determined). The project here is to strengthen and reframe this complaint in a debate-neutral way, and to show how a sober contextualism can uniformly accommodate it and the standard eavesdropping data. Along the way we reject John Hawthorne’s danger-theoretic explanation of these subtleties. (shrink)

I offer an interpretation of Carnap and Quine’s views on cognitive significance and insignificance. The basic idea behind their views is as follows: to judge an expression is insignificant is to recommend it not be used in or explicated into languages used to express truth-valued judgments in inquiry; to judge an expression is significant is to recommend it be used in or explicated into such languages. These judgments are pragmatic judgments, made in light of purposes for (...) language use in inquiry. For Carnap at least, these pragmatic judgments are non-cognitive. This basic idea is only a roughly correct statement of their views. This is because the details of the scientific languages they recommend for inquiry are necessary to understand their views and the way they understand their own views. Even so, I offer two reasons to suggest that this basic idea is worthy of our consideration today. First, it provides a conception of significance that captures the natural thought that epistemological concerns can lead us to consider expressions to be insignificant without requiring an objectionable form of verificationism. Second, if we appeal also to Carnap and Quine’s pluralistic attitude toward explication, we can make a pragmatic judgment that an expression is insignificant while judging it to be significant on a distinct explication of significance fit for describing and explaining natural language.

The paper aims to address the following two questions: what kind of discourse is that which attempt to found or defend the autonomy or the boundaries of a discipline? Why do such discourses tend to turn into normative, dogmatic-excommunicating discourses between disciplines, schools or scholars? I will argue that an adequate answer may be found if we conceive disciplines as dogmatics, where such discourses often take the form of a discourse on the foundation of a discipline, a foundation in the (...) name of which the scholar speaks and with which he/she entertains an identity relationship. To this purpose I will re-examine the methodological discourses of (and debates between) Pareto, Croce and Einaudi on the demarcation issue between philosophy, economics and value-judgments as highly instructive to understand such issues.

This article surveys recent literature by Parsons, McGee, Shapiro and others on the significance of categoricity arguments in the philosophy of mathematics. After discussing whether categoricity arguments are sufficient to secure reference to mathematical structures up to isomorphism, we assess what exactly is achieved by recent ‘internal’ renditions of the famous categoricity arguments for arithmetic and set theory.

ABSTRACTRecent debate over the semantics and pragmatics of epistemic modals has focused on intuitions about cross-contextual truth-value assessments. In this paper, we advocate a different approach to evaluating theories of epistemic modals. Our strategy focuses on judgments of the incompatibility of two different epistemic possibility claims, or two different truth value assessments of a single epistemic possibility claim. We subject the predictions of existing theories to empirical scrutiny, and argue that existing contextualist and relativist theories (...) are unable to account for the full pattern of observed judgments. As a way of illustrating the theoretical upshot of these results, we conclude by developing a novel theory of epistemic modals that is able to predict the results. (shrink)

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 notion of more truth, or of more truth and less falsehood, is central to epistemology. Yet, I argue, we have no idea what this consists in, as the most natural or obvious thing to say—that more truth is a matter of a greater number of truths, and less falsehood is a matter of a lesser number of falsehoods—is ultimately implausible. The issue is important not merely because the notion of more truth and less falsehood is (...) central to epistemology, but because an implicit, false picture of what this consists in underpins and gives shape to much contemporary epistemology.

Abstract: We propose a view of vagueness as a semantic property of names and predicates. All entities are crisp, on this semantic view, but there are, for each vague name, multiple portions of reality that are equally good candidates for being its referent, and, for each vague predicate, multiple classes of objects that are equally good candidates for being its extension. We provide a new formulation of these ideas in terms of a theory of granular partitions. We show that this (...) theory provides a general framework within which we can understand the relation between vague terms and concepts and the corresponding crisp portions of reality. We also sketch how it might be possible to formulate within this framework a theory of vagueness which dispenses with the notion of truth-value gaps and other artifacts of more familiar approaches. Central to our approach is the idea that judgments about reality involve in every case (1) a separation of reality into foreground and background of attention and (2) the feature of granularity. On this basis we attempt to show that even vague judgments made in naturally occurring contexts are not marked by truth-value indeterminacy. We distinguish, in addition to crisp granular partitions, also vague partitions, and reference partitions, and we explain the role of the latter in the context of judgments that involve vagueness. We conclude by showing how reference partitions provide an effective means by which judging subjects are able to temper the vagueness of their judgments by means of approximations. (shrink)

Statements containing epistemic modals (e.g., “by spring 2023 most European countries may have the Covid-19 pandemic under control”) are common expressions of epistemic uncertainty. In this paper, previous published findings (Knobe & Yalcin, 2014; Khoo & Phillips, 2018) on the opposition between Contextualism and Relativism for epistemic modals are re-examined. It is found that these findings contain a substantial degree of individual variation. To investigate whether participants differ in their interpretation of epistemic modals, an experiment with multiple phases and sessions (...) is used to classify participants according to the three semantic theories of Relativism, Contextualism, and Objectivism. Through this study, some of the first empirical evidence for the kind of truth-value shifts postulated by semantic Relativism is presented. It is furthermore found that participants’ disagreement judgments match their truth evaluations and that participants are capable of distinguishing between truth and justification. In a second experimental session, it is investigated whether participants thus classified follow the norm of retraction which Relativism uses to account for argumentation with epistemic modals. Here the results are less favorable for Relativism. In a second experiment, these results are replicated and the normative beliefs of participants concerning the norm of retraction are investigated following work on measuring norms by Bicchieri (2017). Again, it is found that on average participants show no strong preferences concerning the norm of retraction for epistemic modals. Yet, it was found that participants who had committed to Objectivism and had training in logics applied the norm of retraction to might-statements. These results present a substantial challenge to the account of argumentation with epistemic modals presented in MacFarlane (2014), as discussed.

This paper outlines a new pluralistic theory of normative reasons for belief, welfarist pluralism, which aims to explain how there can be basic alethic/epistemic reasons for belief and basic pragmatic/non-alethic reasons for belief that can combine to determine what one ought to believe.

In addition, this paper outlines how (...) welfarist pluralism provides a new and potentialy attractive account of the value of truth (or its indicators), namely that the value of truth (or its indicators) is its direct contribution to individuals' personal good or wellbeing.

What do religious statements tell us? The epistemology of statements to which believers dedicate their lives is of critical importance. Richard Bevan Braithwaite (1900-1990), who considers the statements of religion from a non-cognitive but conative perspective, thinks that even if the religious statements cannot be verified, they can be empirically meaningful. This meaning is analogical, drawing policy of life like in moral judgments. According to Braithwaite, these statements have no truth value as in science; the stories told (...) in a religious language only psychologically support the person to maintain the lifestyle. In short, Braithwaite eliminates the cognitive dimension of religious statements by focusing on the conative aspect. Thus, he tries to make religion meaningful so as not to get caught in the verification principle. We aim to analyze Braithwaite's theory of moral interpretation of religious language. In the introduction part of our study, we will explain the dominant paradigm of the period between 1920-1955 to reveal the reasons that prepared Braithwaite for his empiricist approach to religious belief. In this way, we will handle the verification principle, which is the cornerstone of logical positivism. Afterward, we will try to evaluate Braithwaite's ideas on the moral interpretation of the religious statements under two titles. First of all, we will try to answer from Braithwaite's point of view why religious statements cannot pass the verification test. For this, we will present the reasons for not including religious expressions in the empirical, hypothetical, and analytical categories, respectively, and we will present our criticisms. In the second part, we will find an answer to the question of where the religious statements will take place. We will touch on Braithwaite's effort to make religious expressions meaningful by charging functionality, and we will evaluate the criticisms. Afterward, we will discuss the similarities and differences between religious and moral statements and examine the problems that may arise due to Braithwaite's theory. In addition, we will evaluate Braithwaite's attitude concerning the religious stories and the criticisms toward him to distinguish religions with the same moral action. As a result, we will reveal Braithwaite's perspective on the subjectivity of religious belief and point out the possible drawbacks in terms of theism. (shrink)

Infectious logics are systems that have a truth-value that is assigned to a compound formula whenever it is assigned to one of its components. This paper studies four-valued infectious logics as the basis of transparent theories of truth. This take is motivated as a way to treat different pathological sentences differently, namely, by allowing some of them to be truth-value gluts and some others to be truth-value gaps and as a way to treat (...) the semantic pathology suffered by at least some of these sentences as infectious. This leads us to consider four distinct four-valued logics: one where truth-value gaps are infectious, but gluts are not; one where truth-value gluts are infectious, but gaps are not; and two logics where both gluts and gaps are infectious, in some sense. Additionally, we focus on the proof theory of these systems, by offering a discussion of two related topics. On the one hand, we prove some limitations regarding the possibility of providing standard Gentzen sequent calculi for these systems, by dualizing and extending some recent results for infectious logics. On the other hand, we provide sound and complete four-sided sequent calculi, arguing that the most important technical and philosophical features taken into account to usually prefer standard calculi are, indeed, enjoyed by the four-sided systems.

Philosophers have identified a number of principles that characterize morality and underlie moral judgments. However, philosophy has failed to establish any widely agreed-upon justification for these judgments, and an “error theory” that views moral judgments as without justification has not been successfully refuted. Evolutionary psychologists have had success in explaining the likely origins and mechanisms of morality but have also not established any justification for adopting particular values. As a result, we are left with moral nihilism -- (...) the absence of any unarguable values or behaviors we must or should adopt. The philosophical and psychological implications of this nihilism suggest accepting shared, non-absolute values as “good enough”; a revised, humbler view of moral and other value judgments; and the possible acceptance of the hard truth of a value nihilism.

To say that evidence is normative is to say that what evidence one possesses, and how this evidence relates to any proposition, determines which attitude among believing, disbelieving and withholding one ought to take toward this proposition if one deliberates about whether to believe it. It has been suggested by McHugh that this view can be vindicated by resting on the premise that truth is epistemically valuable. In this paper, I modify the strategy sketched by McHugh so as to (...) overcome the initial difficulty that it is unable to vindicate the claim that on counterbalanced evidence with respect to P one ought to conclude deliberation by withholding on P. However, I describe the more serious difficulty that this strategy rests on principles whose acceptance commits one to acknowledging non-evidential reasons for believing. A way to overcome this second difficulty, against the evidentialists who deny this, is to show that we sometimes manage to believe on the basis of non-epistemic considerations. If this is so, one fundamental motivation behind the evidentialist idea that non-epistemic considerations could not enter as reason in deliberation would lose its force. In the second part of this paper I address several strategies proposed in the attempt to show that we sometimes manage to believe on the basis of non-epistemic considerations and show that they all fail. So, I conclude that the strategy inspired by McHugh to ground the normativity of evidence on the value of truth ultimately fails. (shrink)

The present crisis of truth, the "post-truth" crisis, puts the philosophy of truth in a new light. It calls for a reexamination of the tasks of the philosophy of truth and sets a new adequacy condition on this philosophy. One of the central roles of the philosophy of truth is to explain the importance of truth for human life and civilization. Among other things, it has to explain what is, or will be, lost in (...) a post-truth era. Clearly, the deflationist answer that the role of truth is to serve as a tool of generalization and oblique endorsement will not do. My account of truth in this paper addresses this task. Truth, I argue, is first and foremost a human value. Its importance to our life/civilization lies, not exclusively, but principally, in the centrality of this value to our humanity. I investigate the ramifications of this answer to the issues discussed in the contemporary philosophy of truth, and I end with a comparison of the substantivist and deflationist approaches to truth in light of this new perspective.

Constructivism is a theory that believes moral judgments are not real things but they are constructed by practical reason in a rational procedure for resolving practical problems in front of us. Christine Korsgaard, a contemporary American philosopher, is a Kantian constructivist, whose theory I consider in this paper. She is a radical constructivist and disagrees with moral realism and denies moral truths even as abstract facts. According to Korsgaard moral judgments are constructed by rational agents. She believes moral (...) and political principles are generally solutions to human practical problems. She justifies the normativity of moral obligations from this point that they are constructed by agent for resolving his problems. There are some objections to Korsgaard’s constructivism; one of them is to place humanity as the source of value. Keywords: Korsgaard, constructivism, practical problem, humanity. Introduction One of the traditional problems in moral philosophy is the nature and entity of moral truths and judgments. Do humans themselves make and construct them or are they facts and truths in the world which humans just discover? Are moral truths and values subjective or objective? Subjectivism and objectivism have been two old rivals in this question. But some philosophers have proposed a new theory between them that is called Constructivism. According to this theory, moral truths are not real and objective, but are constructed by human practical reason. In this view, an action is morally right when there is a sufficient reason to perform it. In this paper I will discuss Korsgaard’s constructivism. 1. Definition of Constructivism Constructivism is a theory about the justification of moral principles. It is the view that moral principles are the ones agents would agree with or endorse if they were to engage in a hypothetical or idealized process of rational deliberation. The differences about related criteria for this rational process and deliberation have produced several varieties of constructivism like Humean, Aristotelian, and Kantian. (shrink)

Cheryl Misak (2000; 2008a; 2008b; Misak and Talisse 2014; Misak and Talisse 2021) has presented an argument for democracy based on her analysis of the writings of Charles Sanders Peirce: If we care about the truth of our beliefs – as everyone does, according to Misak – then we ought to support democratic norms and democratic political institutions. We argue in the present paper that Misak’s argument does not adequately justify a democratic political system. Her argument does, however, justify (...) a rational commitment to the standard liberal-democratic values of freedom of expression, freedom of association, and the like. We demonstrate as well that Misak’s argument for the democratic values withstands well-known objections against her argument for a democratic political system. We also show that weaker premises involving every agent’s commitment to pursuing their own subjective ends can get us to Misak’s conclusions regarding liberal values using reasoning otherwise similar to Misak’s in that our alternative premises also get us to the commitment to taking the experiences of others seriously. These weaker premises avoid objections raised against Misak’s Peircean view and are acceptable even to those who reject Misak’s idea, taken from her reading of Peirce, that truth is a constitutive norm of belief.

The thesis deals with the concept of truth and the paradoxes of truth. Philosophical theories usually consider the concept of truth from a wider perspective. They are concerned with questions such as - Is there any connection between the truth and the world? And, if there is - What is the nature of the connection? Contrary to these theories, this analysis is of a logical nature. It deals with the internal semantic structure of language, the mutual (...) semantic connection of sentences, above all the connection of sentences that speak about the truth of other sentences and sentences whose truth they speak about. Truth paradoxes show that there is a problem in our basic understanding of the language meaning and they are a test for any proposed solution. It is important to make a distinction between the normative and analytical aspect of the solution. The former tries to ensure that paradoxes will not emerge. The latter tries to explain paradoxes. Of course, the practical aspect of the solution is also important. It tries to ensure a good framework for logical foundations of knowledge, for related problems in Artificial Intelligence and for the analysis of the natural language. Tarski’s analysis emphasized the T-scheme as the basic intuitive principle for the concept of truth, but it also showed its inconsistency with the classical logic. Tarski’s solution is to preserve the classical logic and to restrict the scheme: we can talk about the truth of sentences of a language only inside another essentially richer metalanguage. This solution is in harmony with the idea of reflexivity of thinking and it has become very fertile for mathematics and science in general. But it has normative nature | truth paradoxes are avoided in a way that in such frame we cannot even express paradoxical sentences. It is also too restrictive because, for the same reason we cannot express a situation in which there is a circular reference of some sentences to other sentences, no matter how common and harmless such a situation may be. Kripke showed that there is no natural restriction to the T-scheme and we have to accept it. But then we must also accept the riskiness of sentences | the possibility that under some circumstances a sentence does not have the classical truth value but it is undetermined. This leads to languages with three-valued semantics. Kripke did not give any definite model, but he gave a theoretical frame for investigations of various models | each fixed point in each three-valued semantics can be a model for the concept of truth. The solutions also have normative nature | we can express the paradoxical sentences, but we escape a contradiction by declaring them undetermined. Such a solution could become an analytical solution only if we provide the analysis that would show in a substantial way that it is the solution that models the concept of truth. Kripke took some steps in the direction of finding an analytical solution. He preferred the strong Kleene three-valued semantics for which he wrote it was "appropriate" but did not explain why it was appropriate. One reason for such a choice is probably that Kripke finds paradoxical sentences meaningful. This eliminates the weak Kleene three valued semantics which corresponds to the idea that paradoxical sentences are meaningless, and thus indeterminate. Another reason could be that the strong Kleene three valued semantics has the so-called investigative interpretation. According to this interpretation, this semantics corresponds to the classical determination of truth, whereby all sentences that do not have an already determined value are temporarily considered indeterminate. When we determine the truth value of these sentences, then we can also determine the truth value of the sentences that are composed of them. Kripke supplemented this investigative interpretation with an intuition about learning the concept of truth. That intuition deals with how we can teach someone who is a competent user of an initial language (without the predicate of truth T) to use sentences that contain the predicate T. That person knows which sentences of the initial language are true and which are not. We give her the rule to assign the T attribute to the former and deny that attribute to the latter. In that way, some new sentences that contain the predicate of truth, and which were indeterminate until then, become determinate. So the person gets a new set of true and false sentences with which he continues the procedure. This intuition leads directly to the smallest fixed point of strong Kleene semantics as an analytically acceptable model for the logical notion of truth. However, since this process is usually saturated only on some transfinite ordinal, this intuition, by climbing on ordinals, increasingly becomes a metaphor. This thesis is an attempt to give an analytical solution to truth paradoxes. It gives an analysis of why and how some sentences lack the classical truth value. The starting point is basic intuition according to which paradoxical sentences are meaningful (because we understand what they are talking about well, moreover we use it for determining their truth values), but they witness the failure of the classical procedure of determining their truth value in some "extreme" circumstances. Paradoxes emerge because the classical procedure of the truth value determination does not always give a classically supposed (and expected) answer. The analysis shows that such an assumption is an unjustified generalization from common situations to all situations. We can accept the classical procedure of the truth value determination and consequently the internal semantic structure of the language, but we must reject the universality of the exterior assumption of a successful ending of the procedure. The consciousness of this transforms paradoxes to normal situations inherent to the classical procedure. Some sentences, although meaningful, when we evaluate them according to the classical truth conditions, the classical conditions do not assign them a unique value. We can assign to them the third value, \undetermined", as a sign of definitive failure of the classical procedure. An analysis of the propagation of the failure in the structure of sentences gives exactly the strong Kleene three-valued semantics, not as an investigative procedure, as it occurs in Kripke, but as the classical truth determination procedure accompanied by the propagation of its own failure. An analysis of the circularities in the determination of the classical truth value gives the criterion of when the classical procedure succeeds and when it fails, when the sentences will have the classical truth value and when they will not. It turns out that the truth values of sentences thus obtained give exactly the largest intrinsic fixed point of the strong Kleene three-valued semantics. In that way, the argumentation is given for that choice among all fixed points of all monotone three-valued semantics for the model of the logical concept of truth. An immediate mathematical description of the fixed point is given, too. It has also been shown how this language can be semantically completed to the classical language which in many respects appears a natural completion of the process of thinking about the truth values of the sentences of a given language. Thus the final model is a language that has one interpretation and two systems of sentence truth evaluation, primary and final evaluation. The language through the symbol T speaks of its primary truth valuation, which is precisely the largest intrinsic fixed point of the strong Kleene three valued semantics. Its final truth valuation is the semantic completion of the first in such a way that all sentences that are not true in the primary valuation are false in the final valuation. (shrink)

The Value of Truth looks at the conditions that truths would have to meet to ascertain a value, as well as the different kinds of values a truth can possess.

It’s widely accepted that normativity is not subject to truth values. The underlying reasoning is that truth values can only be predicated of descriptive statements; normative statements are prescriptive, not descriptive; thus truth value predicates cannot be assigned to normative statements. Hence, deonticity lacks logical semantics. This semantic monism has been challenged over the last decades from a series of perspectives that open the way for legal logics with imperative semantics. In the present paper I will (...) go back to Kant and review his understanding of practical judgments, presenting it as supported by a pluralistic semantics. From this perspective a norm of Law is a logical expression that includes as content a generic description of a possible behavior by a generality of juridical agents, and assigns to that content the assertion of its obligatory character, accompanied by a disincentive for non-compliance. From this perspective legal norms can be syntactically formalized and assigned appropriate semantic values in such terms that they can be incorporated into valid inferential schemes. The consequence is that we can put together legal logics that handle both the phenomenal and the deontic dimensions of legality. (shrink)

This paper is a reply to Michael Lynch's "Truth, Value and Epistemic Expressivism" in Philosophy and Phenomenological Research for 2009. It argues that Lynch's argument against expressivism fails because of an ambiguity in the employed notion of an 'epistemically disengaged standpoint'.

Most epistemologists maintain that true beliefs are of final epistemic value. However, Richard Feldman is a rare philosopher who is skeptical that true beliefs are of final epistemic value. The aim of this paper is to evaluate Feldman’s criticisms. I’ll argue that Feldman’s arguments ultimately turn on a view about the relation between epistemic duties and epistemic value that is implausible and underdeveloped.

Peter Railton argues for a form of moral realism which holds that moral judgments can bear truth values in a fundamental non-epistemic sense of truth; that moral properties are objective, though relational; that moral properties supervene upon natural properties, and may be reducible to them; that moral inquiry is of a piece with empirical inquiry. He also thinks that it cannot be known a priori whether bivalence holds for moral judgments, and that a rational agent may (...) fail to have a reason for obeying moral imperatives, although they may be applicable to him. In this paper, Railton's moral theories are carefully examined and compared with noncognitivistic ones. (shrink)

Truths will be defined as an agreement on uncertainties, the consensus over matters of empirical and social nature such as mathematics, physics or economics. As illustrated by Dennis Lindley , ‘individuals tend to know things to be true and false but the extent of this truth and falsity would always remain unknown’. Leading individuals to a permanent state of stress, uncertainty becomes a risk for the social community. Problems could not be presumed to be solvable as any kind of (...) solution would be perceived as uncertain. The struggle for solutions would develop into a state of insecurity and conflict where no individual could trust the answers given by any other member of the community. To prevent a ‘war of all against all’ that would cause anxiety and permanent conflict, it will become an essential duty for the social community to diminish uncertainty by imposing truths. With those, individuals can be reassured about the certainty of their knowledge and use truths as a resolution tool for any dispute that might occur within the social space. For the purpose of social peace, truths will therefore be every outcome of the process through which uncertainty is transformed into an agreed form of knowledge. “Gravity”, “Death” and “God” will all be considered truths as they represent a form of agreement over different domains of the human and social life. It is not the intention of this essay to examine each of the truths separately but rather, to analyse them all together in order to formulate a hypothesis for all empirical and social matters.

Aesthetic judgments are often expressed by means of predicates that, unlike ‘beautiful’ or ‘ugly’, are not primarily aesthetic, or even evaluative, such as ‘intense’ and ‘harrowing’. This paper aims to explain how such adjectives can convey a value-judgment, and one, moreover, whose positive or negative valence depends on the context.

هو أول كتاب باللغة العربية يعرض لمراحل وآليات تطور المنطق الرمزي المعاصر متعدد القيم بأنساقه المختلفة، مركزًا على مشكلة الغموض المعرفي للإنسان بأبعادها اللغوية والإبستمولوجية والأنطولوجية، والتي تتجلى – على سبيل المثال – فيما تحفل به الدراسات الفلسفية والمنطقية والعلمية من مفارقات تمثل تحديًا قويًا لثنائية الصدق والكذب الكلاسيكية، وكذلك في اكتشاف «هيزنبرج» لمبدأ اللايقين، وتأكيده وعلماء الكمّ على ضرورة التفسيرات الإحصائية في المجال دون الذري، الأمر الذي يؤكد عدم فعالية قانون الثالث المرفوع في التعامل مع معطيات الواقع الفعلي، واستحالة (...) مشروع إقامة لغة مثالية أو اصطناعية أو كاملة منطقيًا تتجاوز عيوب ونقائص اللغة العادية التي نفكر ونتعامل بها. وينتهي الكتاب إلى نتيجة مؤداها أن ما واجهه المنطق الكلاسيكي – ثنائي القيم – من مشكلات أدت إلى تطويره، لاسيما مشكلة الغموض، لابد وأن يواجهه بالمثل المنطق متعدد القيم، ذلك أن الغموض ظاهرة إبستمولوجية في المحل الأول، مردودها إلى الذات العارفة وقصور إمكاناتها الإدراكية والقياسية، لا إلى الوجود ذاته. وأننا حتى لو سمحنا لأية قضية منطقية بقيمة صدق ثالثة، أو بأكثر من قيمة تتوسط بين الصدق التام والكذب التام، فسوف تظل القضية – كتمثيل لغوي لإحدى وقائع العالم – صادقة أو كاذبة، سواء أدركنا ذلك أو لم ندركه، وذلك تأكيد لنزعة أفلاطون الواقعية القائلة بوجود أزلي وثابت للحقائق في عالم المثل، تحول دون معرفتنا الظنية بظلالها في عالم الحس المتغير. ويعني ذلك بعبارة أخرى أن الشك في قانون الثالث المرفوع هو إسقاط من الذات على الموضوع، مبعثه عدم اكتمال العملية المعرفية ومحدوديتها، وأن ظهور الأنساق المنطقية ذات القيم المتعددة ما هو إلا حلقة من حلقات العلاقة الجدلية اللامنتهية بين الإنسان والطبيعة، أو بيم ما هو مُدرك وما هو موجود بالفعل. والكتاب بصفة عامة هو أول كتاب باللغة العربية يعرض لأنساق المنطق متعدد القيم بعد مرحلة البرينكيبيا ماثيماتيكا.

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)

The falsity of moral claims is commonly deduced from two tenets: that they presuppose the existence of objective values and that these values don’t exist. Hence, the error theory concludes, moral claims are false. In this article, I put pressure on the image of human morality that is presupposed in moving from the non-existence of objective values to the falsity of moral claims. I argue that, while, understood in a certain way, the two premises of the error theory are correct, (...) this does not render moral discourse false, because moral objectivity is disanalogous to objectivity in empirical sciences and as such need not be characterized in terms of mind-independency. Using Dewey, I illuminate the possibility of accommodating the guiding intuitions of the error theory in a first-order account of morality. (shrink)

In matters of personal taste, faultless disagreement occurs between people who disagree over what is tasty, fun, etc., in those cases when each of these people seems equally far from the objective truth. Faultless disagreement is often taken as evidence that truth is relative. This article aims to help us avoid the truth-relativist conclusion. The article, however, does not argue directly against relativism; instead, the article defends non-relative truth constructively, aiming to explain faultless disagreement with the (...) resources of semantic contextualism. To this end the article describes and advocates a contextualist solution inspired by supervaluationist truth-value gap approaches. The solution presented here, however, does not require truth value gaps; it preserves both logical bivalence and non-relative truth, even while it acknowledges and explains the possibility of faultless disagreement. The solution is motivated by the correlation between assertions’ being true and their being useful. This correlation, furthermore, is used not only to tell which assertions are true, but also to determine which linguistic intuitions are reliable. (shrink)

In his Encyclopaedia Logic, Hegel affirms that truth is ‘usually’ understood as the agreement of thought with the object, but that in the ‘deeper, i.e. philosophical sense’, truth is the agreement of a content with itself or of an object with its concept. Hegel then provides illustrations of this second sort of truth: a ‘true friend’, a ‘true state’, a ‘true work of art’. Robert Stern has argued that Hegel's ‘deeper’ or ‘philosophical’ truth is close to (...) what Heidegger labelled ‘material’ truth, namely a property attributed to a thing on the basis of the accordance of that thing with its essence. It has since been common to think of Hegel's concept of ‘philosophical’ truth as ‘ontological’, ‘objective’ or ‘material’ in contrast to ‘epistemological’ or ‘propositional’ definitions. In this paper, I wish to add an important nuance to the existing literature on this subject: even though things have a truth-value for Hegel, the latter is always negative. I argue that Hegel's criterion of ‘philosophical’ truth, which is best formulated as ‘agreement with self’, is first and foremost intended to examine the truth-value of thought-determinations. I then argue that even though this criterion may also be applied to examine the truth-value of things (namely, even though things have a truth-value), things never fall under this definition. After reviewing several of Hegel's explicit remarks on the matter, I provide an alternative explanation to those features of Hegel's ‘philosophical’ truth which have led scholars to view it as a truth in things. Especially, I argue that what are generally seen as Hegel's examples (‘true friend’, ‘true state’, ‘true work of art’) are not intended as examples but only as imperfect illustrations of ‘philosophical’ truth.
