Truth, Misc

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 counter-arguments for various proposed solutions (``the revenge of the Liar''). Any solution to the paradoxes of truth necessarily establishes a certain logical concept of truth. 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 a content-wise 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 logical concept of truth. In the end, an erroneous critique of Kripke-Feferman axiomatic theory of truth, which is present in contemporary literature, is pointed out. (shrink)

The concept of truth has many aims but only one source. The article describes the primary concept of truth, here called the synthetic concept of truth, according to which truth is the objective result of the synthesis of us and nature in the process of rational cognition. It is shown how various aspects of the concept of truth -- logical, scientific, and mathematical aspect -- arise from the synthetic concept of truth. Also, it is shown how the paradoxes of truth (...) arise. (shrink)

For any natural (human) or formal (mathematical) language L we know that an expression X of language L is true if and only if there are expressions Γ of language L that connect X to known facts. -/- By extending the notion of a Well Formed Formula to include syntactically formalized rules for rejecting semantically incorrect expressions we recognize and reject expressions that evaluate to neither True nor False.

The article suggests a reading of the term ‘epistemic account of truth’ which runs contrary to a widespread consensus with regard to what epistemic accounts are meant to provide, namely a definition of truth in epistemic terms. Section 1. introduces a variety of possible epistemic accounts that differ with regard to the strength of the epistemic constraints they impose on truth. Section 2. introduces the paradox of knowability and presents a slightly reconstructed version of a related argument brought forward by (...) Wolfgang Künne. I accept the paradox and Künnes argument as sound objections to all the different epistemic accounts which are committed to one of the various constraints on truth introduced in section 1. Section 3. offers a modified epistemic constraint which, or so I argue, is immune to the paradox of knowability and plausible on independent grounds. (shrink)

The thesis that nothing is true has long been thought to be a self-refuting position not worthy of serious philosophical consideration. Recently, however, the thesis of alethic nihilism—that nothing is true—has been explicitly defended (notably by David Liggins). Nihilism is also, I argue, a consequence of other views about truth that have recently been advocated, such as fictionalism about truth and the inconsistency account. After offering an account of alethic nihilism, and how it purports to avoid the self-refutation problem, I (...) argue that it avoids the problem at the expense of changing the subject. I then present other arguments against nihilism and responses to the considerations offered in defense of it. The only tenable position is that something is indeed true. (shrink)

A well-known theory about under which circumstances a statement is true in a fiction is The Reality Principle, which originate in the work of David Lewis: (RP) Where p1... pn are the primary fictional truths of a fiction F , it is true in F that q iff the following holds: were p1 ... pn the case, q would have been the case (Walton 1990: 44). RP has been subjected to a number of counterexamples, up to a point where, in (...) the words of Stacie Friend “it is widely recognized that the Reality Principle […] cannot be a universal inference rule for implied story-truths” (Friend 2017: 33). This chapter argues that the strength of these counterexamples is widely overestimated, and that they do not, on closer scrutiny, constitute reasons for rejecting RP. (shrink)

Kevin Scharp argues that the concept of truth is defective, and is therefore unable to play its intended role in natural language truth-conditional semantics. As such, for this theoretical purpose, Scharp constructs two replacements: ascending truth and descending truth. Scharp applies the resultant theory, AD semantics, to the liar sentence, thereby obtaining a novel solution to the liar paradox. The aim of the present paper is fourfold. First, I show that, contrary to Scharp’s claims, AD semantics in fact yields an (...) inconsistency when applied to standard liar sentences. Second, I diagnose the problem: AD semantics mishandles negation. I propose an alternative treatment, resulting in what I call AD* semantics. Third, I show that AD* semantics gives Scharp the resources required to respond to an alleged revenge paradox that has been raised against his view. Finally, I argue that, these consequences notwithstanding, it remains unclear whether AD* semantics provides an adequate account of alethic paradoxes more generally. (shrink)

This chapter interprets G. E. M. Anscombe’s discussion in §31 of Intention of the relationship between expressions of intention and descriptions of matters of fact. For Anscombe, a statement like “I’m raising my arm” or “I’m going to get up at 7:00”, which expresses an intention by saying what is happening or is going to happen, is contradicted only by an opposing command or the expression of an opposing intention. I first challenge an interpretation of this passage as claiming that (...) the truth of statements like these is somehow independent of whether the action they describe is actually performed. Against this reading, my preferred interpretation highlights the fact that Anscombe is speaking here only of what contradicts expressions of intention, while her position is that statements like these describe the world in ways that will be contrary to, and so truth-functionally incompatible with, any opposing statements of fact.

Understanding Truth aims to illuminate the notion of truth, and the role it plays in our ordinary thought, as well as in our logical, philosophical, and scientific theories. Part one is concerned with substantive background issues: the identification of the bearers of truth, the basis for distinguishing truth from other notions, like certainty, with which it is often confused, and the formulation of positive responses to well-known forms of philosophical skepticism about truth. Part two explicates the formal theories of Alfred (...) Tarski and Saul Kripke, including their treatments of the Liar paradox, and evaluates the philosophical significance of their work. Part three extends important lessons drawn from Tarski and Kripke to new domains: vague predicates, the Sorites paradox, and the development of a larger, deflationary perspective on truth. Part one attempts to diffuse five different forms of truth skepticism, broadly conceived: the view that truth is indefinable, that it is unknowable, that it is inextricably metaphysical, that there is no such thing as truth, and the view that truth is inherently paradoxical, and so must either be abandoned, or revised. An intriguing formulation of the last of these views is due to Alfred Tarski, who argued that the Liar paradox shows natural languages to be inconsistent because they contain defective, and ultimately incoherent, truth predicates. I argue in response that on a plausible interpretation of his puzzling notion of an inconsistent language, Tarski’s argument turns out to be logically valid, but almost certainly unsound, since one of its premises can be seen to be indefensible. Similar results are achieved for other forms of truth skepticism. (shrink)

It seems true to say that Sherlock Holmes is a detective, despite there being no Sherlock Holmes. When asked to explain this fact, philosophers of language often opt for some version of Lewis’s view that sentences like ‘Sherlock Holmes is a detective’ may be taken as abbreviations for sentences prefixed with ‘In the Sherlock Holmes stories …’. I present two problems for this view. First, I provide reason to deny that these sentences are abbreviations. In short, these sentences have aesthetic (...) properties that we should not expect of abbreviations. Second, I argue that the apparent truth of these sentences would not be explained even if they were abbreviations. An alternative is presented that avoids these problems. Following Walton, talk about fiction is viewed as a game of make-believe; following Lewis, interpretations of fiction are modelled using possible worlds. (shrink)

The essential role of language in rational cognition is analysed. The approach is functional: only the results of the connection between language, reality, and thinking are considered. Scientific language is analysed as an extension and improvement of everyday language. The analysis gives a uniform view of language and rational cognition. The consequences for the nature of ontology, truth, logic, thinking, scientific theories, and mathematics are derived.

L’objectivité permettrait d’assurer la supériorité de la science par rapport à d’autres modes de connaissance. Elle doit donc être défendue, surtout en cette « ère de post-vérité » où les « faits alternatifs » remplacent les faits avérés, en politique comme ailleurs. Or les attaques proviennent autant de l’extérieur que de l’intérieur de la sphère philosophique. Il convient donc de tenter d’opérer la réconciliation la plus large possible avec deux représentants de clans (très) opposés, Mario Bunge et Bruno Latour. Réinvestissant (...) les grandes conceptions de la notion d’objectivité, je propose ici trois chantiers pour cette réconciliation : la mise au rancart des conceptions naïves et parfois insincères de la science, la réévaluation des contextes de découverte et de justification, et celle de la distinction faits-valeurs.

S’inspirant de Memorias. Entre dos mundos, ce texte se veut un témoignage et des commentaires de la perspective pédagogique développée par Mario Bunge dans le cadre de son enseignement de philosophie des sciences à l’Université de Buenos Aires dans les années soixante du siècle dernier. Perspective socratique du métier de philosophe qui ne renvoie cependant pas à une entreprise de dévoilement de la vérité, mais plutôt aux conditions de sa construction.

I often tell my students that the only thing that is not controversial in philosophy is that everything else in it is controversial. While this might be a bit of an exaggeration, it does contain a kernel of truth, as many exaggerations do: philosophy is a highly contentious discipline. So it is remarkable the extent to which there is agreement in the philosophy of religion amongst theists, agnostics, and atheists alike that John Mackie’s argument for atheism is either invalid or (...) unsound. As a result, the focus has entirely shifted from the logical problem of evil to the so-called evidential one. But I think that this is a mistake, not necessarily because I think Mackie’s argument is sound, but rather because I reject an assumption made by apparently all parties to the debate, which is that there is only one logical problem of evil. Accordingly, the purpose of this paper is to defend a deductive argument that God* does not exist. As far as I can tell, the basic idea of this argument is a novel one: while Mackie’s argument has a more or less consequentialist framework, mine has a deontological one. The evil of which I will speak is that of our having been thrown into the world. (shrink)

We present here the papers selected for the volume on the Unity of Propositions problems. After summarizing what the problems are, we locate them in a spectrum from those aiming to provide substantive, reductive explanations, to those with a more deflationary take on the problems.

Charles S. Peirce’s semeiotic—his theory about signs, reference, interpretation, meaning, and communication—is applicable with illuminating results to innumerable processes of semeiosis or sign interpretation. Robert C. Neville is the first deep student of Peirce’s semeiotic to have systematically applied that theory to the analysis and theory of theological signs, interpretation, and truth—hereafter, theological semeiotic. The result is easily the deepest and richest theological semeiotic currently available. Being the best, it is also most worthy of critique. In this essay, I argue (...) that Neville misinterprets Peirce’s concept of an index, conceiving an index in terms of the interpreter-object rather than... (shrink)

Lying and fiction both involve the deliberate production of statements that fail to obey Grice’s first Maxim of Quality (“do not say what you believe to be false”). The question thus arises if we can provide a uniform analysis for fiction and lies. In this chapter I discuss the similarities, but also some fundamental differences between lying and fiction. I argue that there’s little hope for a satisfying account within a traditional truth conditional semantic framework. Rather than immediately moving to (...) a fully pragmatic analysis involving distinct speech acts of fiction-making and lying, I will first explore how far we get with the assumption that both are simply assertions, analyzed in a Stalnakerian framework, i.e. as proposals to update the common ground.

El proceso de aprehensión de lo cognoscible, en la filosofía contemporánea, ha sido tratado desde diversas perspectivas, entre ellas la fenomenológica y la analítica. Cada una de estas perspectivas aportan unos presupuestos filosóficos y procesos metodológicos que nos proporcionan marcos de trabajo para indagar en las vías de aprehensión del conocimiento; sin embargo, empleadas por separado son insuficientes y limitadas. En absoluto se trata de procurar un método universal, sino de integrar e indagar sobre diversos presupuestos, procesos, patrones y estructuras (...) para avanzar en la indagación de la aprehensión del conocimiento. En este sentido, en la primera parte, abordaremos la necesidad de tener reglas (definitorias y estratégicas) para ser parte y avanzar en cualquier «juego», en especial el del conocimiento. En la segunda y tercera, describiremos los «métodos» desarrollados por José Ferrater Mora (operaciones filosóficas) y Nicolai Hartmann (pensar sistemático), los que pueden ser un punto de partida, vías a considerar en este proceso. En la parte final, a modo de contraste, se ofrece en un gráfico un esquema metodológico de los dos métodos analizados. (shrink)

A typical guiding principle of an account of truth is: “truth is objective,” or, to be clear, judging whether an assertion is true or false depends upon how things are in the world rather than how someone or some community believes it to be. Accordingly, whenever a claim is objectively true, its truth conditions ought not depend upon the context in which it is uttered or the utterer making the claim. Part of our ongoing empirical studies surveying people’s responses to (...) questions about truth involved prompts on objectivity. Our studies suggest the following: overall, individuals tend to endorse claims that are consistent with the objectivity of truth; not all conceptions of objectivity are equal, even people who endorse the objectivity of truth sometimes assent to one form of truth’s objectivity over other forms; philosophers and non-philosophers both endorse the objectivity of truth, but the apparent commitment of philosophers is stronger.

This essay explores the validity of Gregory Boyd’s open theistic account of the nature of the future. In particular, it is an investigation into whether Boyd’s logical square of opposition for future contingents provides a model of reality for free will theists that can preserve both bivalence and a classical conception of omniscience. In what follows, I argue that it can.

This is a review article (15,000 words) of Putnam's Naturalism, Realism, and Normativity, (Harvard, 2016).

Neste artigo é defendido que 'os iluministas' não poderiam ser capazes de eliminar os preconceitos, como pretendiam, haja vista que atacavam o fenômeno do preconceito onde ele não estava, sendo o entrave no acesso à verdade apenas um efeito colateral do preconceito e não seu elemento central. Independente da possibilidade ou não de se eliminar os preconceitos, a estratégia adotada pelos filósofos desse período estava condenada ao fracasso. Para sustentar esta hipótese, primeiro será extraída uma noção geral do preconceito a (...) partir de autores do período do iluminismo. Em seguida serão estudados seus aspectos a fim de compreender a relação dos preconceitos com a realidade. Por fim se demonstra que o caráter dessa relação é acidental, não podendo o preconceito ser abolido por uma argumentação acerca da verdade das coisas. Este artigo não discute se é possível eliminar os preconceitos, apontando apenas o erro do método dos autores modernos. (shrink)

Providing empirically supportable instances of ontological emergence is notoriously difficult. Typically, the literature has focused on two possible sources. The first is the mind and consciousness; the second is within physics, and more specifically certain quantum effects. In this paper, I wish to suggest that the literature has overlooked a further possible instance of emergence, taken from the special science of linguistics. In particular, I will focus on the property of truth-evaluability, taken to be a property of sentences as created (...) by the language faculty within human minds (or brains). The claim will not be as strong as to suggest that the linguistic data and theories prove emergence. Rather the dialectical aim here is to say that we have some good reasons (even if not conclusive reasons) to think that the property is emergent. (shrink)

The paper seeks to answer two new questions about truth and scientific change: What lessons does the phenomenon of scientific change teach us about the nature of truth? What light do recent developments in the theory of truth, incorporating these lessons, throw on problems arising from the prevalence of scientific change, specifically, the problem of pessimistic meta-induction?

I consider two competing approaches to metasemantics: productivism, whereby endowment with semantic significance emerges directly from conditions surrounding the production or employment of the items semantically endowed; and interpretationism, whereby endowment with semantic significance emerges directly from conditions surrounding the interpretive consumption of such items. Focusing on the version of interpretationism developed by Lewis and his followers, I present a novel argument to the conclusion that such an approach cannot secure determinacy for singular reference. I then draw a larger moral (...) for metasemantics and its relation to truth-conditional semantics. (shrink)

I give a detailed review of 'The Outer Limits of Reason' by Noson Yanofsky 403(2013) from a unified perspective of Wittgenstein and evolutionary psychology. I indicate that the difficulty with such issues as paradox in language and math, incompleteness, undecidability, computability, the brain and the universe as computers etc., all arise from the failure to look carefully at our use of language in the appropriate context and hence the failure to separate issues of scientific fact from issues of how language (...) works. I discuss Wittgenstein's views on incompleteness, paraconsistency and undecidability and the work of Wolpert on the limits to computation. -/- Those wishing a comprehensive up to date account of Wittgenstein, Searle and their analysis of behavior from the modern two systems view may consult my article The Logical Structure of Philosophy, Psychology, Mind and Language as Revealed in Wittgenstein and Searle (2016).

Truth is a pervasive feature of ordinary language, deserving of systematic study, and few theorists of truth have endeavoured to chronicle the tousled conceptual terrain forming the non-philosopher’s ordinary view. Joseph Ulatowski recasts the philosophical treatment of truth in light of historical and recent work in experimental philosophy. He argues that the commonsense view of truth is deeply fragmented along two axes, across different linguistic discourses and among different demographics. Call this endoxic alethic pluralism. To defend this view, four conclusions (...) must be reached: (1) endoxic alethic pluralism should be compatible with how the everyday person uses truth, (2) the common conception of truth should be derivable from empirical data, (3) this descriptive metaphysical project is one aspect of a normative theory of truth, and (4) endoxic alethic pluralism is at least partially immune to challenges facing the ecological method in experimental philosophy and alethic pluralism.

Yablo has argued for an alternative form of if-thenism that is more conducive with his figurative fictionalism. This commentary sets out to challenge whether the remainder, ρ, tends to be an inaccurate representation of the conditions that are supposed to complete the enthymeme from φ to Ψ. Whilst by some accounts the inaccuracies shouldn't set off any alarm bells, the truth of ρ is too inexact. The content of ρ, a partial truth, must display a sensitivity to the contextual background (...) conditions for subtraction to work properly in Yablo's view. Using a toy example, I argue that Yablo's subtraction model tends to yield partial truths as remainders that fail to rule out inaccurate expressions that may prove to be problematic for it. (shrink)

We might suppose it is not only instrumentally valuable for beliefs to be true, but that it is intrinsically valuable – truth makes a non-derivative, positive contribution to a belief's overall value. Some intrinsic goods are better than others, though, and this article considers the question of how good truth is, compared to other intrinsic goods. I argue that truth is the worst of all intrinsic goods; every other intrinsic good is better than it. I also suggest the best explanation (...) for truth's inferiority is that it is not really an intrinsic good at all. It is intrinsically neutral. (shrink)

In this article I try to prove that John Rawls, in his lectures published in _Political Liberalism_ and later works, recommended the independence of one’s world-view and politics, and that at the same time he allowed the existence of non-conflicting factual truths in politics. His reflections on the problem of truth in the political realm are closely related to his reflections on reason, not only the public one. Thus, the aim of this article is to present and analyze Rawls’ understanding (...) of reason and the place and function of truth in politics. (shrink)

A predicate logic typically has a heterogeneous semantic theory. Subjects and predicates have distinct semantic roles: subjects refer; predicates characterize. A sentence expresses a truth if the object to which the subject refers is correctly characterized by the predicate. Traditional term logic, by contrast, has a homogeneous theory: both subjects and predicates refer; and a sentence is true if the subject and predicate name one and the same thing. In this paper, I will examine evidence for ascribing to Aristotle the (...) view that subjects and predicates refer. If this is correct, then it seems that Aristotle, like the traditional term logician, problematically conflates predication and identity claims. I will argue that we can ascribe to Aristotle the view that both subjects and predicates refer, while holding that he would deny that a sentence is true just in case the subject and predicate name one and the same thing. In particular, I will argue that Aristotle's core semantic notion is not identity but the weaker relation of constitution. For example, the predication ‘All men are mortal’ expresses a true thought, in Aristotle's view, just in case the mereological sum of humans is a part of the mereological sum of mortals. (shrink)

Book Review of Charles Travis's Objectivity and the Parochial.

An influential argument against the possibility of truth by linguistic convention holds that while conventions can determine which proposition a given sentence expresses, they (conventions) are powerless to make propositions true or false. This argument has been offered in the literature by Lewy, Yablo, Boghossian, Sider and others. But despite its influence and prima facie plausibility, the argument: (i) equivocates between different senses of “making true”; (ii) mistakenly assumes hyperintensional contexts are intensional; and (iii) relies upon an implausible vision of (...) the way that language works.

In a paper in this journal, I defend the view that truth is the fundamental norm for assertion and, in doing so, reject the view that knowledge is the fundamental norm for assertion. In a recent response, Littlejohn raises a number of objections against my arguments. In this reply, I argue that Littlejohn’s objections are unsuccessful.

I use the principle of truth-maker maximalism to provide a new solution to the semantic paradoxes. According to the solution, AUS, its undecidable whether paradoxical sentences are grounded or ungrounded. From this it follows that their alethic status is undecidable. We cannot assert, in principle, whether paradoxical sentences are true, false, either true or false, neither true nor false, both true and false, and so on. AUS involves no ad hoc modification of logic, denial of the T-schema's validity, or obvious (...) revenge. (shrink)

In his book Perché ancora la filosofia Carlo Cellucci argues that truth does not play any role in (modern) science: truth is only a chimera that prevents us «from adequately understanding the character of knowledge» and therefore «must be disposed of». I summarize Cellucci’s evidence for his contention that truth is a chimera. I then raise four objections to Cellucci’s views on truth. My conclusion is that, Cellucci’s arguments notwithstanding, a notion of truth is necessary for the human activity of (...) problem solving and therefore for an adequate understanding of the phenomenon of knowledge.

This paper discusses the question if there is any truth in art. Initially it poses the question whether artworks are just mere appearances or whether they have a special truth. In critical reflection on Heidegger’s conception of art as the “setting-itself-to-work of truth” this question is then elaborated and answered: The appearance character of artworks cannot be conceived as truth. What true artworks show, namely mere possibilities, is beyond truth, because it does not belong to the real world. Artworks are (...) not true; in their decentered order and their self-showing nature they are beautiful. (shrink)

The aim of this paper is rather modest: we do not intend to reconstruct Aristotle’s theory of truth (although we are convinced that there is such a thing), and we will not try to settle the issue concerning Bivalence in Aristotle. We merely want, on the one hand, to argue for the consistency between the main Aristotelian texts on truth and a possible rejection of Bivalence; and on the other hand, to investigate the conditions of a possible counterexample to Bivalence. (...) The motivation for this research is also very specific. We are interested in the apparent violation of Bivalence introduced by vague predicates, and in particular we want to respond to a family of arguments put forward by T. Williamson in support of the idea that allowing for exceptions to Bivalence would be incoherent. We have focused on these arguments for two reasons. On the one hand, what is allegedly threatened by a denial of Bivalence is no less than the very “nature of truth or falsity”. On the other hand, Aristotle is explicitly mentioned as one of the defendants of this “natural” conception of truth, and we are reminded about the connection between Aristotle’s theory and Tarski’s semantic conception. These arguments, therefore, give us an occasion to explore Aristotle’s analysis of the nature of truth and falsity, and to examine its connection with the Tarskian conception of truth. In particular, we would like to question the assumption, which has become a commonplace in the field of analytical philosophy, that Aristotle’s notion of truth can be encoded in the pair of disquotational biconditionals that derive from Tarski’s “T schema”.

This paper shows that the knowability paradox isn’t a paradox because the derivation of the paradox is faulty. This is explained by showing that the K operator employed in generating the paradox is used equivocally and when the equivocation is eliminated the derivation fails.

Does truth have a history? Whereas Bernard William denies it and only allows a history of truthfulness, I defend the possibility of a critical history or genealogy of truth. Because a trifling relativistic historicization of truth leads to a paradoxically a-historic and pacifistic conception of truth, one must first establish the methodological concepts with which a genealogy of truth can avoid both problems. Three first steps towards such concepts can be found in some of Michel Foucault’s lectures, which lead the (...) genealogy of truth to focus on the origins of truth’s force. (shrink)

This paper provides finitary jointly necessary and sufficient acceptance and rejection conditions for the logical constants of a first order quantificational language. By introducing the notion of making an assignment as a distinct object level practice—something you do with a sentence—(as opposed to a meta-level semantic notion) and combining this with the practice of (hypothetical and categorical) acceptance and rejection and the practice of making suppositions one gains a structure that is sufficiently rich to fully characterize the class of classical (...) first order theories. The analysis thus provides a way of characterizing classical first order quantification by expressivist means. (shrink)

This paper defends a key aspect of the Peircean conception of truth—the idea that truth is in some sense epistemically-constrained. It does so by exploring parallels between Peirce’s epistemology of inquiry and that of Wittgenstein in On Certainty. The central argument defends a Peircean claim about truth by appeal to a view shared by Peirce and Wittgenstein about the structure of reasons. This view relies on the idea that certain claims have a special epistemic status, or function as what are (...) popularly called ‘hinge propositions’. (shrink)
