Truth is a fundamental philosophical concept that, despite its common and everyday use, has resisted common-sense formulations. At this point, one may legitimately wonder if there even is a common-sense notion of truth or what it could look like. In response, I propose here a common-sense account of truth based on four “truisms” that set a baseline for how to go about building an account of truth. Drawing on both ordinary language philosophy and contemporary pragmatic (...) approaches to truth, I defend a pragmatic, common-sense theory of truth. The result is a theory that focuses the use and function of truth while also emphasizing its “subject-independence.”. (shrink)

Even though pragmatic theories of truth are not widely held, they have advantages not found elsewhere. Here I focus on one such advantage: that a pragmatic theory of truth does not limit the range of truth-apt beliefs and thereby “block the way of inquiry.” Furthermore, I argue that this speaks for a particular formulation of the pragmatic theory of truth, one that shifts away from Peircean approaches and their emphasis on temporal (...) independence, and toward a theory that instead emphasizes truth’s subject independence.

The pragmatic theory of truth (PTT) seeks to illuminate the concept of truth by focusing on concepts like usefulness or adaptivity. However, contrary to common opinion, PTT does not merely face a narrow band of (perhaps) rather artificial counterexamples (as in a case of empirically unfounded but life-extending optimism in a cancer patient); instead, PTT is faced with a fast psychological research literature which suggests that inaccurate beliefs are both (1) pervasive in human beings and, nonetheless, (...) (2) fully adaptive in many cases. Call this the "pervasive adaptive illusions" (PAI) objection to PTT. According to PAI, the kind of connection drawn by PTT between the beliefs that we (intuitively or pretheoretically) regard as "true" and the beliefs we regard as useful is undercut by hard-nosed empirical work in psychology -- work that no empirically minded pragmatist can ignore. According to PAI, the connection drawn between truth and utility by PTT is subject to a simply overwhelming set of counterexamples (drawn from psychological research, and reviewed below). Thus, PTT is a theory any sensible theorist of truth must reject. (shrink)

Theories of Truth provides a clear, critical introduction to one of the most difficult areas of philosophy. It surveys all of the major philosophical theories of truth, presenting the crux of the issues involved at a level accessible to nonexperts yet in a manner sufficiently detailed and original to be of value to professional scholars. Kirkham's systematic treatment and meticulous explanations of terminology ensure that readers will come away from this book with a comprehensive general understanding of one (...) of philosophy's thorniest set of topics. -/- Included are discussions of the correspondence, coherence, pragmatic, semantic, performative, redundancy, appraisal, and truth-as-justification theories. There are also chapters or sections of chapters on the liar paradox, three-valued logic, Field's critique of Tarski, Davidson's program, Dummett's theory of linguistic competence, satisfaction, recursion, the extension/intension distinction, and an explanation of how theories of justification, properly understood, differ from theories of truth. -/- A persistent theme is that philosophers have too often failed to recognize that not all theories of truth are intended to answer the same question. When the various questions are made distinct, it is apparent that many of the "debates" in this field are really cases of philosophers talking past one another. There is much less disagreement within the field than has commonly been thought. (shrink)

As the title of my paper indicates, I wish to establish a relationship between the problem of an adequate explication of the truth-conception that underlies modern empirical science and the philosophy of C. S. Peirce who is often called the founder of American Pragmatism. In speaking of the truth-conception of modern empirical science, I am thinking of a conception of truth that is necessarily presupposed for an adequate epistemological and methodological understanding of experimental and theoretical natural science (...) and, indeed, for such types of quasi-nomological social science as can be practiced according to the paradigm of natural science. This means that I do not propose directly to thematize the truth-problematics of so called “hermeneutic Geisteswissenschaften” or “critical-reconstructive social sciences” which, in my opinion, transcend the truth-conception as well as the very concept of science.

There are often said to be five main 'theories of truth': correspondence, coherence, pragmatic, redundancy, and semantic theories. The coherence theory of truth equates the truth of a judgment with its coherence with other beliefs. Different versions of the theory give different accounts of coherence, but in all its forms the point is to exhibit truth as an internal relation between beliefs. The pragmatic theory of truth is akin to a (...) coherence theory of this Kantian kind. No coherence theorist need deny the uncontentious claim that for a judgment to be true is for it to stand in a certain relationship, which can be called correspondence, with some state of affairs in the world. The conflict with the redundancy theory may be more apparent than real. For the redundancy theory is not a theory of what truth consists in, but a theory about the meaning of the words 'is true'.

This paper proposes an alternative view of the connection between knowledge and truth. Truth is traditionally seen as a semantic notion, i.e. a relation between what we say about the world and the world itself. Epistemologists and philosophers of science are therefore apt to resort to correspondence theories of truth in order to deal with the question whether our theories and beliefs are true. Correspondence theories try to define truth, but, in order to do so, they (...) must choose a truth bearer, i.e. something capable of being true, for instance, propositions, sentences or statements. According to the analysis here proposed, none of these truth bearers can be defined without reference to the others. The pragmatic, alternative view here presented, in its turn, is unaffected by this kind of conceptual difficulty. According to this view, one must focus on the use of truth terms – such as ‘true’, ‘false’, ‘correct’, ‘appropriate’, etc. – and the methodological role such terms play in the investigative practices and research programs to be found both in the sciences and in other, everyday investigative activities, such as forensic and journalistic investigations.

: In the 1980s, the analysis of presupposition projection contributed to a ‘dynamic turn’ in semantics: the classical notion of meanings as truth conditions was replaced with a dynamic notion of meanings as Context Change Potentials. We argue that this move was misguided, and we offer an alternative in which presupposition projection follows from the combination of a fully classical semantics and a new pragmatic principle, which we call Be Articulate. This principle requires that a meaning pp’ conceptualized (...) as involving a pre-condition p should be articulated as … … rather than as … pp’ …, unless the full conjunction is ruled out because the first or the second conjunct is semantically idle. In particular, … … is infelicitous - and hence … pp’ … is acceptable - if one can determine as soon as p and is uttered that no matter how the sentence ends these words could be eliminated without affecting its contextual meaning. An equivalence theorem guarantees that this condition suffices to derive Heim’s results in almost all cases. Extensions of the condition lead to several new predictions, in particular concerning some ‘symmetric readings’, as well as presupposition projection in quantified structures, which displays a complex interaction between the nature of the trigger and the monotonicity of the quantifier.

In a number of influential articles published since 1972, Dorothy Grover has developed the prosentential theory of truth. Brought together and published with a new introduction, these essays are even more impressive as a group than they were as single contributions to philosophy and linguistics. Denying that truth has an explanatory role, the prosentential theory does not address traditional truth issues like belief, meaning, and justification. Instead, it focuses on the grammatical role of the (...) class='Hi'>truth predicate and asserts that “it is true” is a prosentence, functioning much as a pronoun does. Grover defends the theory by indicating how it can handle notorious paradoxes like the Liar, as well as by analyzing some English truth-usages. The introduction to the volume surveys traditional theories of truth, including correspondence, pragmatic, and coherence theories. It discusses the essays to come and, finally, considers the implications of the prosentential theory for other theories. Despite the fact that the prosentential theory dismisses the “nature of truth” as a red herring, Grover shows that there are important aspects of traditional truth theories that prosentential theorists have the option of endorsing.

C. S. Peirce claimed that the pragmatic method of clarifying ideas is "nothing but a particular application of an older logical rule, 'By their fruits ye shall know them.'"1 While Jesus spoke about discriminating between true and false religious teachers, Peirce was concerned with clarifying our intellectual concepts. Peirce's pragmatism asserts that we clearly understand the meaning of a concept if we can state the potentially practical and empirical consequences that would follow from the truth of a proposition (...) involving that concept.

ABSTRACT: Cheryl Misak has offered a pragmatic argument against a position she calls Scientific transcendentalists hold that truth is something different from what would be believed at the end of inquiry; more specifically, they adhere to a correspondence theory of truth. Misak thinks scientific transcendentalists thereby undermine the connection between truth and inquiry, for (a) pragmatically speaking, it adds nothing to truth and inquiry to ask whether what would be the results of sufficiently rigorous (...) inquiry are really true and (b) they can only accept it as an article of faith that inquiry leads us to truth. I defend against Misak’s objections. (shrink)

It is generally agreed that constructions of the form “if P, Q” are capable of conveying a number of different relations between antecedent and consequent, with pragmatics playing a central role in determining these relations. Controversy concerns what the conventional contribution of the if-clause is, how it constrains the pragmatic processes, and what those processes are. In this essay, I begin to argue that the conventional contribution of if-clauses to semantics is exhausted by the fact that these clauses introduce (...) a proposition without presenting it as true so that the consequent can be understood in relation to it. Given our cognitive interests in such non-truth-presentational introductions, conditionals will make salient the wide but nevertheless disciplined variety of contents that we naturally attribute to them; no further substantial constraints of the sorts proposed by standard theories of conditionals are needed to explain the phenomena. If this is correct, it provides prima facie evidence for a radically contextualist account of conditionals according to which conditionals have no truth-evaluable or intuitively complete content absent some contextually provided, sufficiently salient relation between antecedent and consequent.

The solution John Buridan offers for the Paradox of the Liar has not been correctly placed within the framework of his philosophy of language. More precisely, there are two important points of the Buridanian philosophy of language that are crucial to the correct understanding of his solution to the Liar paradox that are either misrepresented or ignored in some important accounts of his theory. The first point is that the Aristotelian formula, ` propositio est vera quia qualitercumque significat in (...) rebus significatis ita est ', once amended, is a correct way to talk about the truth of a sentence. The second one is that he has a double indexing theory of truth: a sentence is true in a time about a time, and such times should be distinguished in the account of the truth-conditions of sentences. These two claims are connected in an important way: the Aristotelian formula indicates the time about which a sentence is true. Some interpreters of the Buridanian solution to the paradox, following the lead of Herzberger, have missed these points and have been led to postulate truth-values gaps, or surrogates of truth-value gaps, when there is nothing of this sort in his theory. I argue against this tradition of interpretation of Buridan and propose an interpretation of his solution to the Liar. (shrink)

Despite increased interest in pragmatic theories of truth, Dewey’s approach has not received the same degree of attention as other pragmatists such as Peirce and James. This may seem rather surprising given the sheer quantity Dewey published in his lifetime, much of it focused on issues of epistemology and scientific inquiry. On the other hand, this might seem not surprising at all, since Dewey often went to some effort, especially near the end of his career, to avoid the (...) concept of truth and its associated baggage.1A natural question to ask is whether Dewey even had a theory of truth: that is, a well worked-out position on this crucial philosophical concept. Here, the usual answers—where we can find them—are not... (shrink)

: According to C. S. Peirce, there are two ways of explaining what a sign means, namely, a definition and a precept. A precept tells the interpreters of a sign what the sign means by prescribing what they have to do in order to find or become acquainted with an object of the sign. A precept for a concept specifies how an interpreter can determine whether the concept is applicable to a given situation or object.Peirce accepted the scholastic definition of (...) truth, according to which a proposition is true if and only if its subject and predicate refer to the same thing, and applied this analysis to complex as well as singular propositions. However, this account does not tell how an interpreter can become acquainted with the objects of the predicate "true," that is, true propositions: it is not a good precept for the concept of truth. On the other hand, the so-called pragmatic conception of truth, truth as the limit or end of inquiry, can be regarded as a precept for truth, or as a general form of such a precept.The requirement that concepts should have precepts attached to them is a version of Peirce's principle of pragmatism. The availability of precepts should make it possible for an interpreter to determine whether a concept is applicable to a given situation, or whether a given proposition is true. Thus the principle of pragmatism is closely related to the principle knowability, according to which any truth should be knowable. Some formulations of the principle of knowability lead to a paradox. The paper discusses several forms of the principle of knowability, and it is argued that the existence of precept for a proposition entails only a relatively weak form of the principle.Keywords: Action. Inquiry. Knowledge. Meaning. Peirce. Pragmatism. Precept.Resumo: Segundo C. S. Peirce, há dois modos de explicar o que um signo significa, a saber, uma definição e um preceito. Um preceito diz aos intérpretes de um signo o que o signo significa, prescrevendo o que eles devem fazer para encontrar ou inteirar-se de um objeto do signo. Um preceito para um conceito especifica como um intérprete pode determinar se o conceito é aplicável a uma dada situação ou a um dado objeto.Peirce aceitou a definição escolástica de verdade, segundo a qual uma proposição é verdadeira se, e somente se, seu sujeito e seu predicado se referirem à mesma coisa, e aplicou essa análise tanto a proposições complexas quanto a singulares. Entretanto, essa visão não informa como um intérprete pode inteirar-se dos objetos do predicado "verdadeiro", ou seja, proposições verdadeiras: não é um bom preceito para o conceito de ver- On a Pragmatic Theory of Meaning and Knowledge dade. De outro lado, a assim chamada concepção pragmática de verdade, a verdade como o limite ou fim da investigação, pode ser vista como um preceito para a verdade, ou como uma forma geral de tal preceito.A exigência de que conceitos tenham preceitos ligados a eles é uma versão do princípio do pragmatismo de Peirce . A disponibilidade de preceitos deve tornar possível que um intérprete determine se um conceito é aplicável a uma dada situação, ou seja, se certa proposição é verdadeira. Portanto, o princípio do pragmatismo está intimamente ligado ao princípio da cognoscibilidade, segundo o qual toda verdade pode ser conhecida. Algumas formulações do princípio da cognoscibilidade levam a um paradoxo. O artigo discute algumas formas não-paradoxais do princípio da cognoscibilidade, defendendo que a existência de um preceito para uma proposição exige apenas uma forma relativamente fraca do princípio.Palavras-chave: Ação.

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.

The purpose of this paper is two-fold. First, it aims at developing a preliminary typology of subconscious, tacit mechanisms that underlie the conscious exercise of practical skills as well as the formation and functioning of conscious mental representations such as perceptual experiences, mental images, explicitly held beliefs and explanatory hypotheses. Second, it employs the typology to consider whether these tacit mechanisms can be examined and explicated by what Ryszard Wójcicki calls heuristic theorizing or heuristic reasoning , i.e., by a cognitive (...) procedure whose job is to study one\'s tacit or personal knowledge.

William D’Alessandro has recently argued that there are no implicit truths in fiction. According to the view defended by D’Alessandro, which he terms explicitism, the only truths in fiction are the ones explicitly expressed therein. In this essay, I argue that explicitism is incorrect on multiple counts. Not only is the argument D’Alessandro gives for it invalid, but explicitism as a theory of truth in fiction fails drastically to account for a number of phenomena that are crucial to (...) our understanding and interpretation of fiction, such as pragmatic implicatures and speech acts occurring in fiction, psychological profiles of fictional characters, and fictional truths determined by literary conventions.

From Descartes to Popper, philosophers have criticized and tried to improve the strategies of reasoning invoked in science and in everyday life. In recent years leading cognitive psychologists have painted a detailed, controversial, and highly critical portrait of common sense reasoning. Stephen Stich begins with a spirited defense of this work and a critique of those writers who argue that widespread irrationality is a biological or conceptual impossibility.Stich then explores the nature of rationality and irrationality: What is it that distinguishes (...) good reasoning from bad? He rejects the most widely accepted approaches to this question approaches which unpack rationality by appeal to truth, to reflective equilibrium or conceptual analysis. The alternative he defends grows out of the pragmatic tradition in which reasoning is viewed as a cognitive tool. Stich's version of pragmatism leads to a radical epistemic relativism and he argues that the widespread abhorrence of relativism is ill founded. (shrink)

Two Experiments demonstrate the existence of a “collapse illusion”, in which reasoners evaluate Truthteller-type propositions (“I am telling the truth”) as if they were simply true, whereas Liar-type propositions (“I am lying”) tend to be evaluated as neither true nor false. The second Experiment also demonstrates an individual differences pattern, in which shallow reasoners are more susceptible to the illusion. The collapse illusion is congruent with philosophical semantic truth theories such as Kripke's (1975), and with hypothetical thinking (...) class='Hi'>theory's principle of satisficing, but can only be partially accounted for by the model theory principle of truth. Pragmatic effects related to sentence cohesion further reinforce hypothetical thinking theory interpretation of the data, although the illusion and cohesion data could also be accounted for within a modified mental model theory.

Quine rejects Peirce's theory of truth because, among other things, its notion of a limit of a sequence of theories is defective in that the notion of a limit depends on that of nearer than which is defined for numbers but not for theories. This paper shows that the missing definition of nearer than applied to theories can be supplied from within Quine's own epistemology. The upshot is that either Quine's epistemology must be rejected or Peirce's pragmatic (...) theory of truth is partially vindicated. (shrink)

A central concern of Joseph Heath's Communicative Action and Rational Choice is to find a plausible response to “the problem of convergence … to explain why we should ever expect to secure agreement on moral questions”. In Chapter 7 of his book, Heath proposes what he calls “a pragmatic theory of convergence.” This account is presented as contrasting with the one proposed by Jürgen Habermas, which emphasizes the existence of an internal relation between convergence and moral truth. (...) According to Habermas, there is a “connection … between moral cognitivism and the expectation of convergence”. One cannot take moral judgements to be amenable to rational justification unless one also assumes that an agreement among those participating in the discursive evaluation of that moral judgement is possible in principle. Heath considers this claim about a supposed internal connection as a remnant of foundationalism in Habermas's otherwise promissory contextualist account of moral justification. To reject non-cognitivism, according to Heath, we need not demonstrate that convergence on moral judgement is always forthcoming. It is enough to show that ordinary moral thinking takes moral claims as amenable to discursive justification. As to whether actual practices of discursive justification of moral claims will indeed end in agreement or convergence, a “wait and see” attitude seems all we can legitimately hope for. (shrink)

Subjective predicates have two interpretive and distributional characteristics that have resisted a comprehensive analysis. First, the use of a subjective predicate to describe an object is in general felicitous only when the speaker has a particular kind of familiarity with relevant features of the object; characterizing an object as _tasty,_ for example, implies that the speaker has experience of its taste. Second, subjective predicates differ from objective predicates in their distribution under certain types of propositional attitude verbs. The goal of (...) this paper is to argue that these features can be explained in a uniform way and within a broadly truth-conditional approach to semantic content, given a view of subjective language as an essentially pragmatic, context-sensitive phenomenon. Specifically, we propose that what renders an issue subjective in discourse is speakers’ awareness of _counterstance contingency_: contingency relative to information states that represent alternative pragmatic stances.

In this paper, I give a systematic account of the core features of Jürgen Habermas’s revised approach to truth that comprises both realist and epistemic components. While agents in the lifeworld are pragmatic realists and work on the basic assumption that their beliefs about the world are true, beliefs that have become problematic can be scrutinized only in the form of validity-claims in rational discourses. Thus Habermas introduces a discursive truth predicate that involves a procedural idealization of (...) the conditions of discourse in terms of ‘justified acceptability under conditions that are currently ideal’. He argues that this truth predicate has to be understood in connection with agents’ pragmatic realism to give a comprehensive account of truth. This paper is concerned with the tension between truth-in-the-lifeworld and discursive truth. I argue that Habermas’s account is troubled by two problems: firstly an unclear conception of the role of the truth predicate; and secondly, the suggestion that agents in discourse temporarily abandon their lifeworldly realism. While the first problem can be remedied by exploring the distinction between a truth predicate and a truth criterion, the second difficulty requires a modification of Habermas’s account. I show that the consistency of his approach depends on the acceptance of the principle of bivalence throughout, and hence on the subscription to a certain kind of realism that extends beyond the lifeworld. Key Words: bivalence • discourse • Habermas • lifeworld • pragmatism • realism • truth. (shrink)

Nicholas Rescher tackles the major questions of philosophical inquiry, pondering the nature of truth and existence. In the authoritative voice and calculated manner that we’ve come to expect from this distinguished philosopher, Rescher argues that the development of knowledge is a practice, pursued by humans because we have a need for its products. This pragmatic approach satisfies our innate urge as humans to make sense of our surroundings. Taking his discussion down to the level of particular details, and (...) addressing such topics as inductive validation, hypostatization fallacies, and counterfactual reasoning, Rescher abandons abstract generalities in favor of concrete specifics. For example, philosophers usually insist that to reason logically from a counterfactual, we must imagine a possible world in which the statement is fact. But Rescher argues that there’s no need to attempt to accept the facts of a world outside our cognition in order to reason from them. He shows us how we can use our own natural system of prioritizing, our own understanding of the fundamental, to resolve the inconsistencies in such statements as, “If the Eiffel Tower were in Manhattan, then it would be in New York State.” In using dozens of real-world examples such as these, and in arguing in his characteristically succinct style, Rescher casts light on a wide variety of concrete issues in the classical theory of knowledge, and reassures us along the way that the inherent limitations on our knowledge are no cause for distress. In pragmatic theory and inquiry, we must accept that the best we can do is good enough, because we only have a certain set of tools and conceptualizations available to us. A unique synthesis, this endeavor into pragmatic epistemology will be of interest to scholars and students of philosophy and cognitive science. (shrink)

Although fallacies have been common since Aristotle, until recently little attention has been devoted to identifying and defining them. Furthermore, the concept of fallacy itself has lacked a sufficiently clear meaning to make it a useful tool for evaluating arguments. Douglas Walton takes a new analytical look at the concept of fallacy and presents an up-to-date analysis of its usefulness for argumentation studies. Walton uses case studies illustrating familiar arguments and tricky deceptions in everyday conversation where the charge of fallaciousness (...) is at issue. The numerous case studies show in concrete terms many practical aspects of how to use textual evidence to identify and analyze fallacies and to evaluate arguments as fallacious. Walton looks at how an argument is used in the context of conversation. He defines a fallacy as a conversational move, or sequence of moves, that is supposed to be an argument that contributes to the purpose of the conversation but in reality interferes with it. The view is a pragmatic one, based on the assumption that when people argue, they do so in a context of dialogue, a conventionalized normative framework that is goal-directed. Such a contextual framework is shown to be crucial in determining whether an argument has been used correctly. Walton also shows how examples of fallacies given in the logic textbooks characteristically turn out to be variants of reasonable, even if defeasible or questionable arguments, based on presumptive reasoning. This is the essence of the evaluation problem. A key thesis of the book, which must not be taken for granted as previous textbooks have so often done, is that you can spot a fallacy from how it was used in a context of dialogue. This is an innovative and even, as Walton notes, "a radical and controversial" theory of fallacy. (shrink)

In 1971 Jürgen Habermas delivered the Gauss Lectures at Princeton University. These pivotal lectures, entitled "Reflections on the Linguistic Foundation of Sociology," anticipate The Theory of Communicative Action and offer an excellent introduction to it. They show why Habermas considers the linguistic turn in social philosophy to be necessary and contain the first formulation of formal pragmatics, including an important discussion of truth.In these lectures and two additional essays, Habermas outlines an intersubjective approach to social theory that (...) takes the concepts of meaning and communication to be central. In doing so, he situates his project relative to other influential accounts of how meaning is constituted, in particular those of Edmund Husserl, Wilfrid Sellars, and Ludwig Wittgenstein. He examines the nature of social interaction and its connection to communication, developing a linguistic conception of convention and intentionality. He also offers an account of social and individual pathologies using the concept of systematically distorted communication. Taken together, these analyses contribute significantly to current debates in the philosophy of action and language. (shrink)

The book offers a proposal on how to define truth in all its complexity, without reductionism, showing at the same time which questions a theory of truth has to answer and which questions, although related to truth, do not belong within the scope of such a theory. Just like any other theory, a theory of truth has its structure and limits. The semantic core of the position is that truth-ascriptions are pro-forms, (...) i.e. natural language propositional variables. The book also offers an explanation of the syntactic behaviour of truth-terms, and the pragmatic roles of truth-acts. The theory of truth we present is a technical proposal, relatively uncontaminated by radical philosophical discussion. It makes indeed philosophical points, but it is intended to be a conceptual analysis, as neutral as possible, of the aspects that may serve as a point of departure for more philosophically-laden destinations. Like the Fregean account of quantifiers, which is prior to and, to a large extent, independent of the metaphysical debate about existence and its forms, or the Kaplanian view on demonstratives, that is neutral regarding the debate about individuals and the possibilities we have to actually “reach” them in a referring act, we intend our proposal about truth to be a sophisticated and explicative setting that helps to situate other debates about truth accurately, far from the distorted and sometimes strongly ideological discussions that have turned the topic into a paradigm of philosophical impasse.

Problem of truth and reality is age old in the field of philosophy as well as in the field of science. People very often confuse between ‘Truth’ and ‘Reality’ Most people think them to be one and the same, but there are differences. Whatever exist is real, reality and existence are interchangeable words. We can say truth, which is unchangeable and reality, which exist but change. False, which is not exist at all. People have suggested various taste (...) to decide the truth falsity of our description of reality. Some suggested Pragmatic theory and some other have suggested Coherence as a test of truth. Realism is also an ontological theory and has been probably the most ancient one. According to ancient man, real is that which perceived. Latter on, due to religious impact the knower became more important then the knowing object. Barkeley developed an extreme position that the objective material world does not exist at all. Dewey has developed the position called Instrumentalism. Halt, Perry, Marvin, Pitkin are the chief advocates of this position. Philosophers such as Darke, Lovejoy, Cellars, and Santayana held a position of Critical Realism. These people hold that mind does not see the object directly as they are but only through their representatives, as regards the object of knowledge is concerned, the Neo Realist are monist while Critical Realist are dualist. Indian rationalist philosopher Dr. D.D. Bandiste introduces a new concept of reality Radical Realism. He proved that knowledge change the knower not the object. to him every new knowledge make some change or other inthe knowing person. Epistemological position of john Dewey called instrumentalism. According to him knowledge is an instrument of action and a meaningful action is always of a problem-solving type. Every knowledge is an instrument to serve some need or other, neither is any knowledge final, nor is any truth final. Not only everything in the world is changing, their mutual relations also change. Knowledge is not a goal, but only a instrument to achieve this or that goal. In my paper I haves discussed various theories regarding whether knowledge change the object known. In this contest I have discussed varieties of realism, Idealismand so on, but importantly I have also discussed a new theory Radical Realism. (shrink)

Truth is as central topic in philosophy: formal theories study the connections between truth and logic, including the intriguing challenges presented by paradoxes like the Liar.

In this doctoral thesis, I will argue that in his De motu (1721, ‘On motion’), Bishop George Berkeley (c.1684–1753) develops a pragmatist theory of causation regarding mechanical theories outlined previously with Newtonianism. I place chief emphasis on the importance of logic and mathematics in Berkeley’s scientific approach, on which the other levels of semantics, epistemology, and mechanics build up. On my rendering, Berkeley’s pragmatic method to conceive or mathematically imagine causation makes sense in terms of mechanical causes or (...) ‘mathematical hypotheses’. For the mechanist maintains the usefulness and truthfulness of causation by the following definition. Definition. A pragmatist theory of causation is one which holds that: 1 Causal terms are indispensable in scientific deliberation for their usefulness; they cannot be eliminated [contra reductionism]. 2 What a cause is is defined by one’s temporal deliberative practices, independent of a temporal structure that theories hold [contra structuralism]. 3 Causal laws (theories formulated in causal terms) are genuinely true, not fictitious, when one confirms and deduces them [contra instrumentalism]. By justifying this definition, I will object to three rival readings—reductionism, structuralism, and instrumentalism—to my reading of Berkeley as a pragmatist about causation. In particular, my pragmatist reading criticises the most popular instrumentalist reading because, according to the latter, talk of causal terms like forces can be false or merely fictitious inasmuch as one can hold the utility of theories in mechanical practices. The instrumentalist reading is then compatible with mathematical formalism, according to which it is not truth or meaning that counts as formal manipulation or game of meaningless symbols, thereby eschewing a platonist attitude towards mathematical objects. However, I rebut the formalistic instrumentalism from Berkeley’s logical and realist standpoint, maintaining the irreducibility of occult qualities that mathematical objects have in their formulation from hypotheses to propositions. Light shall be shed on the tenet I propose that law-propositions formulated in hypothetical, causal terms must be true, neither false nor fictitious, when we (1) frame, (2) confirm, and (3) express them to the extent of our discursive thinking (in three steps).

One of the most influential men of his time, philosopher, psychologist, educator, and author William James (1842-1910) helped lead the transition from a predominantly European-centered nineteenth-century philosophy to a new "pragmatic" American philosophy. Helping to pave the way was his seminal book Pragmatism (1907), in which he included a chapter on "Truth," an essay which provoked severe criticism. In response, he wrote the present work, an attempt to bring together all he had ever written on the theory (...) of knowledge, including an article on the function of cognition, later polemic and expository contributions, and some replies to previous criticism. The result was a full and definitive expression of the pragmatist "epistemology" from James' point of view. In the book, he urges the reader to "turn away from abstractions, verbal solutions, fixed principles, and pretended absolutes and look for concreteness and facts, action and power," arguing that "the ultimate test for us of what a truth means is the conduct it dictates or inspires." For students, scholars--anyone interested in William James or the history of American philosophical thought--this book offers an in-depth exposition of the influential ideas of one of the greatest American thinkers.

Pragmatic theories of truth need to pass the pragmatic test: they need to make a difference. Unfortunately, defenders of the pragmatic theory have rarely applied this test. I argue that a Deweyan pragmatic account of truth passes the test by identifying the political and epistemic dangers of certain types of social networks that create a durable consensus around false beliefs. To better understand Dewey’s account of truth I propose an excursion through Wittgenstein’s (...) later views on knowledge and certainty. (shrink)

Pragmatists are usually very antagonistic toward the correspondence theory of truth. They contend that the evidence-transcendent standard entailed by the theory is antithetical to the pragmatist methodology of elucidating concepts by exposing their practical bearings. What use could truth be to us if it offers a target we cannot even see? After judging the correspondence theory to be in violation of the Pragmatic Maxim, the pragmatist is prone to banishing it to the wastelands of (...) empty metaphysics, where nothing of practical importance could ever grow. This article makes the case that this unjust condemnation must be appealed and overturned. The ground for my case is an argument to the effect that the correspondence conception of truth can be practically advantageous, which provides proof of the fact that, contrary to popular pragmatist belief, the correspondence theory does comply with the Pragmatic Maxim.
