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 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.

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.

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'.

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. The paper shows how this non-derivative first-order pluralism arises from a purely welfarist account of the foundations of theoretical normativity, thereby combining foundational pragmatism with non-derivative pluralism about normative reasons for belief. 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.

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.

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.

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.

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)

It has come to be widely accepted that jus post bellum includes responsibilities to rebuild. Consequently, duties to establish a sustainable peace are increasingly defined in terms of duties to protect and promote international human rights, including duties to effectively investigate human rights violations, to ensure access to effective remedy, and to transform institutional and legal contexts that have facilitated or sustained human abuse. But what are investigations by transitional bodies seeking when they take on these tasks? Often, investigators present (...) themselves as seeking the truth and claim value for their findings based on having produced a better description or explanation than was antecedently available. But is truth worth pursuing for its own sake in transitions from conflict or must it contribute to some other goal to be valuable? In what follows I argue that the value of truth in transitions from conflict lies in the role of truth in ascribing knowledge. The connection between truth and knowledge makes it important to preserve distinctively epistemological grounds for accepting and rejecting claims and narratives. These distinctively epistemological grounds explain how, if it is conceived of as adequate responsiveness to experience, truth is a legitimate and important goal in transitions from violence that is worth pursuing for its own sake. In particular, I argue that there is value in insisting that adequate responsiveness to experience serve as an arbiter in the reception of claims and narratives because when responsiveness to experience plays an arbitral role it becomes possible for bodies such as truth commissions to serve as vehicles by which groups may attain or ascribe knowledge.

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.

The value of up-hill skiing is double, it is first a sport and artistic expression, second it incorporates functional dependencies related to the natural obstacles which the individual aims to overcome. On the artistic side, M. Dufrenne shows the importance of living movement in dance, and we can compare puppets with dancers in order to grasp the lack of intentional spiritual qualities in the former. The expressivity of dance, as for, Chi Gong, ice skating or ski mountaineering is a (...) particular innocence and lightness which is called grace. It is life without the burden of worries. Grace, in slow progression uphill on snow, is as dance for Dufrenne, it has the most central and specific aesthetical quality of life. Others compared dance to a landscape, a landscape is for the sight, what dance is for life, a symbolical space, different from a usual space, where utility and dependency are present. A mountain can be a space of experience of natural beauty. Aesthetical qualities can be closely related to function related qualities as when a climber needs to adjust his movements to the natural convex inclination of the rocks, and avoid slippery forms of inclination, present on the other side of the mountain. The natural object, the quality of the snow or the rock differ from the aesthetical quality of the style of ascent by the absence of neutralization of the object, in case of a purely instrumental approach. On the contrary, grace in the rhythm of the progression of ski climbers needs a difference of attitude, which is not only proper to the playing, and delimited by the conditions of that play, but as a contingency driven attitude, without signification as radical alterity, without any finality. First ascent of the Matterhorn succeeded from the Swiss side, and not from the Italian side because of the different inclination of the rock on both sides. Grace in dance as in martial art or mountaineering is allowing to perceive an autonomy of the expression, as the truth of the perceived object, it puts away a cognitive and practical orientation and replaces it by a new meaning as movement in the whole set of movements done by the climber. This replacement of the functional expression resembles that operated by the painter who chooses a color in the whole set of colors in a painting, or a shape in the whole set of possible existing shapes. -/- Ref.

This paper explores the idea that it is instrumentally valuable to learn normative truths. We consider an argument for "normative hedging" based on this principle, and examine the structure of decision-making under moral uncertainty that arises from it. But it also turns out that the value of normative information is inconsistent with the principle that learning *empirical* truths is instrumentally valuable. We conclude with a brief comment on "metanormative regress.".

Like William James before him, Huw Price has influentially argued that truth has a normative role to play in our thought and talk. I agree. But Price also thinks that we should regard truth-conceived of as property of our beliefs-as something like a metaphysical myth. Here I disagree. In this paper, I argue that reflection on truth's values pushes us in a slightly different direction, one that opens the door to certain metaphysical possibilities that even a Pricean (...) pragmatist can love.

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.

Some moral theories, such as objective forms of consequentialism, seem to fail to be practically useful: they are of little to no help in trying to decide what to do. Even if we do not think this constitutes a fatal flaw in such theories, we may nonetheless agree that being practically useful does make a moral theory a better theory, or so some have suggested. In this paper, I assess whether the uncontroversial respect in which a moral theory can be (...) claimed to be better if it is practically useful can provide a ground worth taking into account for believing one theory rather than another. I argue that this is not the case. The upshot is that if there is a sound objection to theories such as objective consequentialism that is based on considerations of practical usefulness, the objection requires that it is established that the truth about what we morally ought to do cannot be epistemically inaccessible to us. The value of practical usefulness has no bearing on the issue. (shrink)

This article informally presents a solution to the paradoxes of truth and shows how the solution solves classical paradoxes (such as the original Liar) as well as the paradoxes that were invented as counterarguments for various proposed solutions (“the revenge of the Liar”). This solution complements the classical procedure of determining the truth values of sentences by its own failure and, when the procedure fails, through an appropriate semantic shift allows us to express the failure in a classical (...) two-valued language. Formally speaking, the solution is a language with one meaning of symbols and two valuations of the truth values of sentences. The primary valuation is a classical valuation that is partial in the presence of the truth predicate. It enables us to determine the classical truth value of a sentence or leads to the failure of that determination. The language with the primary valuation is precisely the largest intrinsic fixed point of the strong Kleene three-valued semantics (LIFPSK3). The semantic shift that allows us to express the failure of the primary valuation is precisely the classical closure of LIFPSK3: it extends LIFPSK3 to a classical language in parts where LIFPSK3 is undetermined. Thus, this article provides an argumentation, which has not been present in contemporary debates so far, for the choice of LIFPSK3 and its classical closure as the right model for the truth predicate. In the end, an erroneous critique of Kripke-Feferman axiomatic theory of truth, which is present in contemporary literature, is pointed out. (shrink)

Assertion is fundamental to our lives as social and cognitive beings. Philosophers have recently built an impressive case that the norm of assertion is factive. That is, you should make an assertion only if it is true. Thus far the case for a factive norm of assertion been based on observational data. This paper adds experimental evidence in favor of a factive norm from six studies. In these studies, an assertion’s truth value dramatically affects whether people think it (...) should be made. Whereas nearly everyone agreed that a true assertion supported by good evidence should be made, most people judged that a false assertion supported by good evidence should not be made. The studies also suggest that people are consciously aware of criteria that guide their evaluation of assertions. Evidence is also presented that some intuitive support for a non-factive norm of assertion comes from a surprising tendency people have to misdescribe cases of blameless rule-breaking as cases where no rule is broken.

Some philosophers (e.g., Pritchard, Grimm, and Hills) recently have objected that veritism cannot explain the epistemic value of understanding-why. And they have proposed two anti-veritist accounts. In this paper, I first introduce their objection and argue that it fails. Next, I consider a strengthened version of their objection and argue that it also fails. After that, I suggest a new veritist account: Understanding-why entails believing the truth that what is grasped is accurate (or accurate enough), and it is (...) this true belief, along with many other true beliefs understanding-why entails, that makes understanding-why finally epistemically valuable. Then, I explain why the two anti-veritist accounts are both false. Finally, I briefly discuss the idea that understanding involves a kind of know-how and show how veritism can explain the epistemic value of know-how in general. (shrink)

The aim of this dissertation is to offer and defend a correspondence theory of truth. I begin by critically examining the coherence, pragmatic, simple, redundancy, disquotational, minimal, and prosentential theories of truth. Special attention is paid to several versions of disquotationalism, whose plausibility has led to its fairly constant support since the pioneering work of Alfred Tarski, through that by W. V. Quine, and recently in the work of Paul Horwich. I argue that none of these theories meets (...) the correspondence intuition---that a true sentence or proposition in some way corresponds to reality---despite the explicit claims by each to capture this intuition. I distinguish six versions of the correspondence theory, and defend two against traditional objections, standardly taken as decisive against them, and show, plainly, that these two theories capture the correspondence intuition. Due to the importance of meeting this intuition, only these two theories stands a chance of being a satisfactory theory of truth. I argue that the version of the correspondence theory incorporating a simple semantic representation relation is preferable to its rival, for which the representation relation is complex. I present and argue for a novel version of this correspondence theory according to which truth is a correspondence property sensitive to semantic context. One consequence of this context-sensitivity is that an ungrounded sentence does not express a proposition. In addition to accounting for the similarity between the Liar and Truth-Teller sentences, this theory of truth is immune to the Liar Paradox, including empirical versions. It is argued that the Liar Paradox is devastating to all of the other theories above, and even formal theories of truth designed to solve it, such as the revision and vagueness theories. Customized versions of the Liar Paradox besetting this theory are handled by its context-sensitivity, and by enforcing the distinction between truth and truth value. This same pair of considerations also yields solutions to Lob's Paradox and Grelling's Paradox. Arguments similar to those given to defend this correspondence theory show that with one minor alteration, Kripke's fixed point theory may be used to model this correspondence notion of truth.

A theory of truth is introduced for a first--order language L of set theory. Fully interpreted metalanguages which contain their truth predicates are constructed for L. The presented theory is free from infinite regress, whence it provides a proper framework to study the regress problem. Only ZF set theory, concepts definable in L and classical two-valued logic are used.

This paper presents a conception of corruption informed by epistemic democratic theory. I first explain the view of corruption as a disease of the political body. Following this view, we have to consider the type of actions that debase a political entity of its constitutive principal in order to assess corruption. Accordingly, we need to consider what the constitutive principle of democracy is. This is the task I undertake in the second section where I explicate democratic legitimacy. I present democracy (...) as a procedure of social inquiry about what ought to be done that includes epistemic and practical considerations. In the third section, I argue that the problem of corruption for a procedural conception of democracy is that the epistemic value of the procedure is diminished by corrupted agents’ lack of concern for truth. Corruption, according to this view, consists in two deformities of truth: lying and bullshit. These deformities corrupt since they conceal private interests under the guise of a concern for truth. In the fourth section, I discuss the difficulties a procedural account may face in formulating solutions to the problem of corruption. (shrink)

On the basis of elementary thinking about language functioning, a solution of truth paradoxes is given and a corresponding semantics of a truth predicate is founded. It is shown that it is precisely the two-valued description of the maximal intrinsic fixed point of the strong Kleene three-valued semantics.

Post-truth has an impression that the facts have been only corrupted with it. Many examples support this impression. However, it should not be perceived as just a disruption of the truth considering only political events. In different fields, such as creative industries, it may have different implications. Despite studies regarding education, there has not been much discussion on the design process and education. The objective of this research is to develop an introductory examination of what the design process (...) (with statements in the book 'How Designers Think') can produce in post-truth cases and to seek the productive potentials of post-truth. Therefore, the claims were reviewed - as design problems, solutions and process itself - within the framework of the post-truth era. Some of the results are as follows: For design problems, designers need to find a way to oscillate among objectives without based on truth. Post-truth environments may trigger finding out unique spatial possibilities with designs of unique hierarchies. For design solutions, in post-truth era, the only optimal thing is to be apathetic about truth. There is no need to seek the optimal solutions. The ideal of wholeness is expired for the solutions. This situation fosters free circulations of tiny parts of solutions in the post-truth universe. For the design process, the correctness of the process is much more questionable anymore. Identifying problem is a crucial part of the design process. As the truth disappears, it becomes more difficult to discriminate the characteristics and value of the problems. (shrink)

A prevalent political narrative is that we are facing an epistemological crisis, where many citizens no longer care about truth and facts. Yet the view that we are living in a post-truth era relies on some implicit questionable empirical and normative assumptions. The post-truth rhetoric converts epistemic issues into motivational issues, treating people with whom we disagree as if they no longer believe in or care about truth. This narrative is also dubious on epistemic, moral, and (...) political grounds. It is epistemically dubious in being largely insensitive to the problem of complexity in politics; it is morally dubious because “post-truth” is often a derogatory label for individuals or groups that are deemed stupid, irrational, or morally compromised; and it is a politically toxic neologism because it purports to use the language of ‘truth’ as a weapon against power, yet these truth-claims are often themselves attempts to exert power over others by delegitimizing their perspectives. While it may seem as if truth and democracy are on especially bad terms lately, politics and truth have long had a vexed relationship, and moral panics about the value of truthfulness in politics are as old as politics itself.

Based on a crowdsourced truth value judgment experiment, we provide empirical evidence challenging two classical views in semantics, and we develop a novel account of counterfactuals that combines ideas from inquisitive semantics and causal reasoning. First, we show that two truth-conditionally equivalent clauses can make different semantic contributions when embedded in a counterfactual antecedent. Assuming compositionality, this means that the meaning of these clauses is not fully determined by their truth conditions. This finding has a clear (...) explanation in inquisitive semantics: truth-conditionally equivalent clauses may be associated with different propositional alternatives, each of which counts as a separate counterfactual assumption. Second, we show that our results contradict the common idea that the interpretation of a counterfactual involves minimizing change with respect to the actual state of affairs. We propose to replace the idea of minimal change by a distinction between foreground and background for a given counterfactual assumption: the background is held fixed in the counterfactual situation, while the foreground can be varied without any minimality constraint.

Our thesis is that there is a notion of justification, corresponding to the active exercise of a competence in order to attain truth, whose value is explained neither by reliabilism, nor by the usual versions of credit theory.

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.

ABSTRACT One striking feature of On the Genealogy of Morals is how it is written. Nietzsche employs a literary style that provokes his readers' emotions. In Beyond Selflessness, Christopher Janaway argues that such a literary approach is integral to Nietzsche's philosophical goals. Feeling the emotions Nietzsche's style arouses is necessary for understanding the views he defends. I argue that Janaway's position is mistaken. The evidence at our disposal fails to establish that emotion is ever necessary for cognition. However, I maintain (...) that we do have good evidence for a slightly weaker claim. The emotionally sensitive person is epistemically better off than the cold and dispassionate person. There are some truths he or she will be more likely to believe and will have better reasons for believing. I conclude that Janaway is right to defend the philosophical importance of Nietzsche's literary writing style. His error is simply that he overstates the case. (shrink)

Cardinal Bessarion (1408–1472), in the second chapter of the first book of his influential work In calumniatorem Platonis, attempted to reply to Georgios Trapezuntios’ (1396–1474) criticism against Plato in the Comparatio Philosophorum Platonis et Aristotelis. Bessarion investigates why the Athenian philosopher maintained, in several dialogues, that the sacred truths should not be communicated to the general public and argued in favor of the value of oral transmission of knowledge, largely based on his theory about the cognitive processes. Recently, Fr. (...) Bessarion Kouotsis has argued that Cardinal Bessarion’s reasoning draws primarily on the “Disciplina Arcani”, i.e., the rule of secrecy, which was an established practice of the Early Christian Church, aimed at protecting and preserving the core elements of the religion from outsiders. While I find Kouotsis’ approach interesting and thought-provoking—for instance, the idea that Bessarion’s argumentation was likely influenced by Eastern Christian views on the rule of secrecy—I intend, first of all, to discuss why Bessarion did not explicitly mention it. Moreover, I would like to argue that Bessarion’s good knowledge of the long Platonic tradition and Eastern mysticism, encompassing both pagan and Christian elements, should also be considered a significant source. Furthermore, I would like to question Kouotsis’ implicit argument that Bessarion’s views were dominated by his training in Orthodox theology and discuss the possibility that Pletho’s (1355–1454) teaching was the obvious influence for Bessarion’s defense of secrecy. After all, we should bear in mind that Anastos has already pointed out Pletho’s reverence for the rule of secrecy. Finally, I would like to support that Bessarion, in the specific text, focused predominantly on the epistemological and cognitive aspects of oral teaching, resorting to the rule of secrecy only to enhance his views.

Epistemic humility, a cornerstone of philosophical and scientific inquiry, emphasizes the recognition of human fallibility and the provisional nature of knowledge. This concept contrasts with epistemic arrogance by promoting a humble acknowledgment of the limits of understanding and a willingness to revise beliefs in light of new evidence. Historical perspectives, from Socrates' dialogues to Descartes' methodological doubt and Hume's critique of induction, illustrate the evolution of epistemic humility as a critical component of skeptical thought. Philosophical reflections on intellectual virtues, such (...) as curiosity and open-mindedness, underscore the importance of embracing uncertainty in the pursuit of truth. Contemporary discourse on epistemic humility addresses its role in scientific progress, public policy, and societal dialogue, highlighting its potential to foster intellectual integrity and informed decision-making amidst complexity and uncertainty.

What do you know when you know what a sentence means? According to some theories, understanding a sentence is, in part, knowing its truth-conditions. Dorit Bar-On, Claire Horisk, and William Lycan have defended such theories on the grounds of an “epistemic determination argument”. That argument turns on the ideas that understanding a sentence, along with knowledge of the non-linguistic facts, suffices to know its truth-value, and that being able to determine a sentence’s truth-value given knowledge (...) of the non-linguistic facts is knowing its truth-conditions. I argue that the EDA withstands the objections recently raised by Daniel Cohnitz and Jaan Kangilaski, but fails for other reasons. It equivocates between a fine-grained and a coarse grained conception of “facts.”. (shrink)

Like many 19th c. thinkers, Kierkegaard embraces a cognitivist view of art. He thinks works of art matter because they can teach us in important ways. This chapter defends two striking features of Kierkegaard’s version of this theory. First, works of art do not teach “directly” by telling us truths and offering us evidence. Instead, they educate us “indirect-ly” by helping us make our own discoveries. Second, the fact that art does not teach in a straightforward manner is no defect. (...) On the contrary, it is precisely because art teaches indirectly that it teaches better than philosophy and science do. (shrink)

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.

The law views with suspicion statistical evidence, even evidence that is probabilistically on a par with direct, individual evidence that the law is in no way suspicious of. But it has proved remarkably hard to either justify this suspicion, or to debunk it. In this paper, we connect the discussion of statistical evidence to broader epistemological discussions of similar phenomena. We highlight Sensitivity – the requirement that a belief be counterfactually sensitive to the truth in a specific way – (...) as a way of epistemically explaining the legal suspicion towards statistical evidence. Still, we do not think of this as a satisfactory vindication of the reluctance to rely on statistical evidence. Knowledge – and Sensitivity, and indeed epistemology in general – are of little, if any, legal value. Instead, we tell an incentive-based story vindicating the suspicion towards statistical evidence. We conclude by showing that the epistemological story and the incentive-based story are closely and interestingly related, and by offering initial thoughts about the role of statistical evidence in morality.

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)

One of the most prominent myths in analytic philosophy is the so- called “Fregean Axiom”, according to which the reference of a sentence is a truth value. In contrast to this referential semantics, a use-based formal semantics will be constructed in which the logical value of a sentence is not its putative referent but the information it conveys. Let us call by “Question Answer Semantics” (thereafter: QAS) the corresponding formal semantics: a non-Fregean many-valued logic, where the meaning (...) of any sentence is an ordered n-tupled of yes-no answers to corresponding questions. A sample of philosophical problems will be approached in order to justify the relevance of QAS. These include: (1) illocutionary forces, and the logical analysis of speech-acts; (2) the variety of logical negations, and their characterization in terms of restricted ranges of logical values; (3) change in meaning, and the use of dynamic oppositions for belief sets.

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.

A pervasive and influential argument appeals to trivial truths to demonstrate that the aim of inquiry is not the acquisition of truth. But the argument fails, for it neglects to distinguish between the complexity of the sentence used to express a truth and the complexity of the truth expressed by a sentence.

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)

Why does knowledge matter? Two answers have been influential in the recent literature. One is that it has value: knowledge is one of the goods. Another is that it plays a significant normative role: knowledge is the norm of action, belief, assertion, or the like. This paper discusses whether one can derive one of the claims from the other. That is, whether assuming the idea that knowledge has value — and some defensible general hypotheses about norms and values (...) —, we could derive the claim that it plays the alleged normative role. Or whether, assuming that knowledge does play that role — and some defensible general hypotheses —, we could derive the claim that it has value. It argues that the route from Value to Norms is unsuccessful. The main problem here is that the idea that knowledge has value does not seem enough to derive the idea that one should act on what one knows. It finds the route from Norms to Value more promising, though a complete path is missing. The main idea here is that knowledge is good because it is normatively required to do good things, such as believing the truth and acting in view of true propositions. But since not all normative conditions for doing something good is itself good, we still lack an explanation of why knowledge would be so. The paper finally suggests an alternative perspective, on which we do not try to derive the idea that knowledge has value from its normative role, but rather use its normative role to explain away the idea that it has value.

A lot has been written on solutions to the semantic paradoxes, but very little on the topic of general theories of paradoxicality. The reason for this, we believe, is that it is not easy to disentangle a solution to the paradoxes from a specific conception of what those paradoxes consist in. This paper goes some way towards remedying this situation. We first address the question of what one should expect from an account of paradoxicality. We then present one conception of (...) paradoxicality that has been offered in the literature: the fixed-point conception. According to this conception, a statement is paradoxical if it cannot obtain a classical truth-value at any fixed-point model. In order to assess this proposal rigorously we provide a non-metalinguistic characterization of paradoxicality and we evaluate whether the resulting account satisfies a number of reasonable desiderata.

Transient Truths: An Essay in the Metaphysics of Propositions provides the first book-length exposition and defense of semantic temporalism, the view that propositions are contents or semantic values that can change their truth-values across time.

At the first Online Philosophy Conference back in 2006, I offered some pretty thorough comments on Joshua Knobe and Erica Roedder's x-phi studies on valuing. While they suggested that our concept of valuing involves moral considerations, I argue here that we can explain the observed asymmetries in attribution of values by appeal to the Principle of Charity, even if the concept of valuing is purely psychological and descriptive. Roughly, to make sense of people with conflicted attitudes, we tacitly attribute to (...) them background attitudes that make them come out as lovers of the good as well as believers of truths and as rational as possible.

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.

Straightening the current ‘value-laden turn’ (VLT) in the philosophical literature on values in science, and reviving the legacy of the value-free ideal of science (VFI), this paper argues that the influence of extra-scientific values should be minimised—not excluded—in the core phase of scientific inquiry where claims are accepted or rejected. Noting that the original arguments for the VFI (ensuring the truth of scientific knowledge, respecting the autonomy of science results users, preserving public trust in science) have not (...) been satisfactorily addressed by proponents of the VLT, it proposes four prerequisites which any model for values in the acceptance/rejection phase of scientific inquiry should respect, coming from the fundamental requirement to distinguish between facts and values: (1) the truth of scientific knowledge must be ensured; (2) the uncertainties associated with scientific claims must be stated clearly; (3) claims accepted into the scientific corpus must be distinguished from claims taken as a basis for action. An additional prerequisite of (4) simplicity and systematicity is desirable, if the model is to be applicable. Methodological documents from international institutions and regulation agencies are used to illustrate the prerequisites. A model combining Betz’s conception (stating uncertainties associated with scientific claims) and Hansson’s corpus model (ensuring the truth of the scientific corpus and distinguishing it from other claims taken as a basis for action) is proposed. Additional prerequisites are finally suggested for future research, stemming from the requirement for philosophy of science to self-reflect on its own values: (5) any model for values in science must be descriptively and normatively relevant; and (6) its consequences must be thoroughly assessed.

In this paper I analyze the difficult question of the truth of mature scientific theories by tackling the problem of the truth of laws. After introducing the main philosophical positions in the field of scientific realism, I discuss and then counter the two main arguments against realism, namely the pessimistic metainduction and the abstract and idealized character of scientific laws. I conclude by defending the view that well-confirmed physical theories are true only relatively to certain values of the (...) variables that appear in the laws. (shrink)
