Coherence Theory of Truth

►JOHN CORCORAN AND IDRIS SAMAWI HAMID, Two-method errors: having it both ways. Philosophy, University at Buffalo, Buffalo, NY 14260-4150, USA E-mail: [email protected] Philosophy, Colorado State University, Fort Collins, CO 80523-1781 USA E-mail: [email protected] Where two methods produce similar results, mixing the two sometimes creates errors we call two-method errors, TMEs: in style, syntax, semantics, pragmatics, implicature, logic, or action. This lecture analyzes examples found in technical and in non-technical contexts. One can say “Abe knows whether Ben draws” in two other (...) ways: ‘Abe knows whether or not Ben draws’ or ‘Abe knows whether Ben draws or not’. But a stylistic TME occurs in ‘Abe knows whether or not Ben draws or not’. One can say “Abe knows how Ben looks” using ‘Abe knows what Ben looks like’. But syntactical TMEs are in ‘Abe knows what Ben looks’ and in ‘Abe knows how Ben looks like’. One can deny that Abe knows Ben by prefixing ‘It isn’t that’ or by interpolating ‘doesn’t’. But a pragmatic TME occurs in trying to deny that Abe knows Ben by using ‘It isn’t that Abe doesn’t know Ben’. There are several standard ways of defining truth using sequences. Quine’s discussions in the 1970 first printing of Philosophy of logic [3] and in previous lectures were vitiated by mixing two [1, p. 98]. The logical TME in [3], which eluded Quine’s colleagues, was corrected in the 1978 sixth printing [2]. But Quine never explicitly acknowledged, described, or even mentioned the error. This lecture presents and analyses two-method errors in the logic literature. [1] JOHN CORCORAN, Review of Quine’s 1970 Philosophy of Logic. In Philosophy of Science, vol. 39 (1972), pp. 97–99.

Neurath (1932) suggests that in our quest for scientific knowledge “we are like sailors who have to rebuild their ship on the open sea, without ever being able to dismantle it in dry-dock and reconstruct it from its best components”. Neurath's boat features in discussions of various philosophical ideas, including the debate with foundationalism and coherentism about justification, the ethics literature on reflective equilibrium, and naturalistic approaches to metaphilosophy.

If, as expressivists maintain, the function of normative thought and talk is not to represent or describe the world, then how can normative judgements be correct or incorrect? In particular, how can I make sense of my own normative fallibility, the possibility that my own normative judgements might be mistaken? In this paper, I construct and defend a substantive but non-representational theory of normative (in)correctness for expressivists. Inspired by Blackburn’s (1998: 318) proposal that I make sense of my fallibility in (...) terms of the possibility that my judgements might be unstable through improvement, my account is designed in the first instance to vindicate the expressivist’s conception of the nature of normative inquiry. I then defend the proposal from the charge that it leaves insufficient room for my own fallibility, and in particular from Egan’s (2007) argument that it implies a “smug” asymmetry between myself and others. Critical to the response is the appeal to indeterminacy in cases of fundamental normative disagreement between reasonable normative outlooks. (shrink)

The concept of truth and competing philosophical theories on what truth amounts to have an important place in contemporary philosophy. The aim of this chapter is to give a synopsis of different theories of truth and the particular philosophical issues related to the concept of truth. The literature on this topic is vast, and we must necessarily be rather selective and very brief about complex questions of interpretation of various philosophers. The focus of the chapter is mainly on selected systematic (...) issues and the most influential and well-established philosophical theories and key concepts. (shrink)

Most philosophers have largely downplayed any relevance of multiple meanings of the folk concept of truth in the empirical domain. However, confusions about what truth is have surged in political and everyday discourse. In order to resolve these confusions, we argue that we need a more accurate picture of how the term ‘true’ is in fact used. Our experimental studies reveal that the use of ‘true’ shows substantial variance within the empirical domain, indicating that ‘true’ is ambiguous between a correspondence (...) and a coherence reading. We then explore the consequences of these results for the project of re-engineering truth. (shrink)

Truth pluralists say that the nature of truth varies between domains of discourse: while ordinary descriptive claims or those of the hard sciences might be true in virtue of corresponding to reality, those concerning ethics, mathematics, institutions might be true in some non-representational or “anti-realist” sense. Despite pluralism attracting increasing amounts of attention, the motivations for the view remain underdeveloped. This paper investigates whether pluralism is well-motivated on ontological grounds: that is, on the basis that different discourses are concerned with (...) different kinds of entities. Arguments that draw on six different ontological contrasts are examined: concrete versus abstract entities; mind-independent versus mind-dependent entities; sparse versus merely abundant properties; objective versus projected entities; natural versus non-natural entities; and ontological pluralism. I argue that the additional premises needed to move from such contrasts to truth pluralism are either implausible or unmotivated, often doing little more than to bifurcate the nature of truth when a more theoretically conservative option is available. If there is a compelling motivation for pluralism, I suggest, it’s likely to lie elsewhere. (shrink)

Introduction: Interdisciplinary, transdisciplinary and action research of a city in lockdown. As we write this chapter, most cities across the world are subject to a similar set of measures due to the spread of COVID-19 coronavirus, which is now a global pandemic. Independent of city size, location, or history, an observer would note that almost all cities have now ground to a halt, with their citizens being confined to their private dwellings, social and public gatherings being almost entirely forbidden, and (...) commercial areas being nearly devoid of visitors. Striking as these apparent similarities are, closer scrutiny would reveal important differences between cities and within cities – differences that can be highly relevant to consider when scholars are assessing the responses of cities to this pandemic or trying to predict the consequences of those responses. For example, the public health systems in some cities are better prepared than in others for coping with the increasing number of patients in life threatening conditions. Multigenerational households, which are associated with a greater risk for elderly members, are not equally common in all cities. Tourist destinations have taken a more severe economic hit from the lockdown than those cities which are economically less dependent upon this particular source of income. Communal celebrations in one city will result in a higher number of contagions and perhaps even deaths in this situation, whereas that same social fabric generally does contribute to a population’s health. The pandemic has also had unprecedented effects on differences and inequalities within cities. In cities in the United States, neighborhoods primarily inhabited by African Americans have been disproportionately affected by COVID-19 due to living and health conditions, yet also due to the fact they disproportionately perform vital jobs. Parks and green spaces are crowded, while city centers like Amsterdam’s Red Light District have suddenly lost the bustle of tourism, providing opportunities for citizens to reoccupy scarce public spaces and reclaim ownership. Clearly, such differences between cities are in many cases only discernible to the eye of an expert, possessing the necessary background knowledge to interpret the perceptible local changes caused by the global pandemic. Typically, drawing upon his or her disciplinary training, the expert also knows how to further probe the impact of the pandemic in an appropriate way. However, compared to the usual application of expertise, this crisis situation might, in an unusual way, test even experts. For the pandemic has created a unique situation, imposing unfamiliar constraints on the health, economic, social, and other conditions of cities, constraints that interact in sometimes unexpected ways with each other. Such interactions in turn force experts to collaborate across the boundaries commonly associated with disciplines, their concepts, theories, methods, and assumptions (Klein, 1996). These brief observations of how a virus pandemic can have differential impacts upon various cities, and what this exceptional situation might mean for the application of city methods, allow us to draw a few consequences for the current context of this chapter on interdisciplinary and transdisciplinary research. First, whenever we are investigating a complex and dynamic phenomenon it is by no means easy to determine which disciplinary perspectives are required to do justice to it. Indeed, the choice of useful disciplines can only be made after an initial overview of the situation and a preliminary selection of what appear to be the most important features of the situation. Relevance is key in guiding this selection process and scholars must remain open to the possibility that they may need to revise their earlier assessments of what is relevant and what is not. Second, if scholars from different disciplines were to study different features of a city in isolation, their ‘multidisciplinary’ account would miss important dynamic and complex interactions, such as those between a city’s demographics and geographical situation, its governance and economy. In other words, it is the integration of the perspectives of different disciplines that is crucial, as only then are such interactions taken into account. Indeed, this integration between disciplinary perspectives is what distinguishes an interdisciplinary from a multidisciplinary account. Thirdly, in addition to checking the relevance of disciplines and aiming for their integration, the outcome of interdisciplinary and transdisciplinary research has typically limited generalizability. Since a city is sensitive to a multitude of internal and external dynamical factors, in ways that partly rest upon its socio-cultural history, its investigation will often have the nature of a case study rather than be capable of leading to law-like insights (Krohn, 2010; Menken & Keestra, 2016). As can be seen from these three characteristics of ascertaining the relevance of different disciplinary contributions, the challenge of their integration, and the limited generalizability of their results owing to the specificity of interdisciplinary (ID) and transdisciplinary (TD) research, such research into ‘real world problems’ is clearly distinct from most monodisciplinary research. A consequence of this distinction is the absence of a general ID/TD methodology that can guide specific case studies. By contrast, the collaboration implied in such research requires researchers – and stakeholders, if they are involved – to reflect upon their potential contribution and the implicit assumptions associated with that. We will elaborate on this in the next section. Next, we offer several typologies of integration that urban scholars could employ for their research projects, after which we will offer a few brief analyses of initial collaborations of urban research. Finally, we discuss in more detail the process of the interdisciplinary research project. This will include a brief reflection upon the decision-making process that is implied in such projects. In sum, we aim to provide some guidance in conducting an ID/TD project, albeit not in the form of a definite methodology. (shrink)

I challenge the assumption that the pragmatist-, coherence-, identity- and deflationary theories of truth are essentially incompatible and rival views to the correspondence theory, without endorsing pluralism. With the exception of some versions of the identity theory, the alternative theories only appear to genuinely contradict the correspondence theory, either when they are wedded to a rejection of an objective reality, or when it is assumed that a ‘theory of truth’ is a theory of the function of the truth-predicate. I argue (...) that the correspondence theory should not be understood as a theory about the function of the truth-predicate, and that the core ideas of the alternative views, once separated from any anti-realist convictions, are best understood as complementary views about different aspects of a fairly complex phenomenon, notably of how our beliefs relate to their subject matter and how we reason and talk about that relation.

Notwithstanding what the champions of post-truth may think, truth remains a key concept of scientific research. In this contribution, several theories of factual truth are evaluated with the help of a simple and straightforward tool, i.e., a logical table of contingency. Its application shows that most contemporary disconcerting theories of truth have critical flaws, and that, albeit imperfect, truth-as-correspondence is still the best theory. Further criticism of correspondence as adaequatio, compliance and isomorphism suggests that correspondence-as-mapping constitutes a more acceptable theory. (...) This contribution provides a definition and examples in the empirical sciences. (shrink)

Catherine Rowett presents an in depth study of Plato's Meno, Republic and Theaetetus and offers both a coherent argument that the project in which Plato was engaging has been widely misunderstood and misrepresented, and detailed new readings of particular thorny issues in the interpretation of these classic texts.

This edited volume brings together 18 state-of-the art essays on pluralism about truth and logic. Parts I and II are dedicated to respectively truth pluralism and logical pluralism, and Part III to their interconnections. Some contributors challenge pluralism, arguing that the nature of truth or logic is uniform. The majority of contributors, however, defend pluralism, articulate novel versions of the view, or contribute to fundamental debates internal to the pluralist camp. The volume will be of interest to truth theorists and (...) philosophers of logic, as well as philosophers interested in relativism, contextualism, metaphysics, philosophy of language, semantics, paradox, epistemology, or normativity.

Putnam and Davidson both defended coherence theories of justification from the early 1980s onward. There are interesting similarities between these theories, and Putnam’s philosophical development lead to further convergence in the 1990s. The most conspicuous difference between Putnam’s and Davidson’s theories is that they appear to fundamentally disagree on the role and nature of conceptual schemes, but a closer look reveals that they are not as far apart on this issue as usually assumed. The veridicality of perceptual beliefs is a (...) cornerstone of both Davidson’s and Putnam’s later (but not earlier) coherentism. However, this thesis introduces a form of weak foundationalism into their theories, and consequently, those are strictly speaking not pure coherence theories, but hybrids between coherentism and foundationalism.

This paper examines a difficulty for various forms of truth pluralism, known in the literature as the problem of ‘mixed atomics’. It is argued that two prominent attempts to respond to the difficulty—those of Jeremy Wyatt and Gila Sher—fail. In their place, an alternative is offered based on parts of Crispin Wright’s Truth and Objectivity programme. It is argued that the Wrightian approach works because it substitutes traditional conceptions of truth-relevant properties, for example correspondence and coherence, for criteria of objectivity (...) pertaining to discursive practices. This allows us to give expression to the nuanced way in which the pluralist wants to treat mixed atomics. (shrink)

Is truth itself natural? This is an important question for both those working on truth and those working on naturalism. For theorists of truth, answering the question of whether truth is natural will tell us more about the nature of truth (or lack of it), and the relations between truth and other properties of interest. For those working on naturalism, answering this question is of paramount importance to those who wish to have truth as part of the natural order. In (...) this paper, we focus primarily on the kinds of theories of truth that occupy the central positions in current debates about truth, namely correspondence theories, deflationary theories, epistemic theories, and pluralist theories, and aim to discern the extent to which truth is a natural property on each view.

Coherence is a measure of how much our beliefs hang together. Understanding is achieved when we see that something is not just a brute, isolated fact. This suggests that it might be possible to develop a coherence theory of understanding, which is what we attempt to do in this article using several formal measures of coherence. However, it turns out that a coherence theory runs into trouble with the asymmetry of understanding. We identify four difficulties and give suggestions for how (...) they could be solved. These solutions all point away from coherence and towards a rather different notion, unification, which casts some doubt on the possibility of a coherence theory of understanding. (shrink)

The paper deals with the notions of consistency, completeness, and coherence within the normative domain. It investigates their mutual relations by singling out relative and absolute consistency, weak, strong and trivial completeness, and three different functions of coherence. The main upshot of the inquiry is that coherence may be regarded as a complex combination of weak completeness and possible absence of consistency and strong completeness of a system of rules regarding a non-trivially complete/non-absolutely inconsistent system of underlying principles.

What is truth? Is there anything that all truths have in common that makes them true rather than false? Is truth independent of human thought, or does it depend in some way on what we believe or what we would be justified in believing? In what sense, if any, is it better for beliefs or statements to be true than to be false? In this engaging and accessible new introduction Chase Wrenn surveys a variety of theories of the nature of (...) truth and evaluates their philosophical costs and benefits. Paying particular attention to how the theories accommodate realist intuitions and make sense of truth’s value, he discusses a full range of theories from classical correspondence to relatively new deflationary and pluralist accounts. The book provides a clear, non-technical entry point to contemporary debates about truth for non-specialists. Specialists will also find new contributions to those debates, including a new argument for the superiority of deflationism to causal correspondence and pluralist theories. Drawing on a range of traditional and contemporary debates, this book will be of interest to students and scholars alike and anyone interested in the nature and value of truth. (shrink)

Why should coherence be an epistemic desideratum? One response is that coherence is truth-conducive: mutually coherent propositions are more likely to be true, ceteris paribus, than mutually incoherent ones. But some sets of propositions are more coherent, while others are less so. How could coherence be measured? Probabilistic measures of coherence exist; some are identical to probabilistic measures of confirmation, while others are extensions of such measures. Probabilistic measures of coherence are fine when applicable, but many situations are so information-poor (...) that the requisite probabilities cannot be determined. To measure coherence in these cognitively impoverished situations, this article proposes that the discussion be broadened to include plausibilistic measures of coherence. It shows how plausibilistic measures of coherence can be defined using plausibilistic measures of confirmation. It then illustrates how plausibilisic coherence can be measured in situations where probabilistic coherence cannot be determined. The coherence values obtained through the use of plausibilistic measures are often, though not always, comparable. The article also shows that coherence can be instantiated on different levels, one of which permits connections to inductive strength and deductive validity. (shrink)

The concept of truth arises from puzzling over distinctions between the real and the apparent, while the origin of these distinctions lies in the neurobiology of mammalian cerebral lateralization, that is, in the evolution of brains that can address the world both indicatively and subjunctively; brains that represent the world both categorically and hypothetically. After some 2,500 years of thinking about it, the Western philosophical tradition has come up with three major theories of truth: correspondence, coherence, and pragmatist. Traditional philosophy (...) has nevertheless failed to arbitrate much among these views; certainly no clear winner has emerged. I argue, however, that contemporary neuroscience provides adequate theoretical grounds for a unified theory of truth. More specifically, I contend that the correspondence, the coherence, and the pragmatic utility of symbols are each biological features of our neurophysiological information processing systems—that is to say, our brains. On my view, the traditional trifurcation of philosophical accounts of the predicate, “is true”, stems from a trifurcation of focus on the information latent in sensory, motor, and somatosensory cortices of the human brain.

Philosophers and scientists agree that an important characteristic of theories is their internal coherence. I propose that there is a particular type of internal coherence, termed “unit coherence,” that has received insufficient attention from psychologists. When psychologists theorize about the mechanisms that bring about human behavior, the units in which the variables are expressed need to be consistent throughout the theory; this is unit coherence. The theory of reasoned action is an example of a unit incoherent theory. I explain why (...) this is so and also show how the theory can be made to be unit coherent. I also include examples of unit coherent theories to demonstrate that they are possible to have in psychology. Although the concept of unit coherence is somewhat subtle, it has surprising and far-reaching consequences. (shrink)

Although it’s sometimes thought that pluralism about truth is unstable—or, worse, just a non-starter—it’s surprisingly difficult to locate collapsing arguments that conclusively demonstrate either its instability or its inability to get started. This paper exemplifies the point by examining three recent arguments to that effect. However, it ends with a cautionary tale; for pluralism may not be any better off than other traditional theories that face various technical objections, and may be worse off in facing them all.

A common objection to coherentism is that it cannot account for truth: it gives us no reason to prefer a true theory over a false one, if both theories are equally coherent. By extending Susan Haack's crossword metaphor, the authors argue that there could be circumstances under which this objection is untenable. Although these circumstances are remote, they are in full accordance with the most ambitious modern theories in physics. Coherence may perhaps be truth conducive.

Coherentists on epistemic justification claim that all justification is inferential, and that beliefs, when justified, get their justification together (not in isolation) as members of a coherent belief system. Some recent work in formal epistemology shows that “individual credibility” is needed for “witness agreement” to increase the probability of truth and generate a high probability of truth. It can seem that, from this result in formal epistemology, it follows that coherentist justification is not truth-conducive, that it is not the case (...) that, under the requisite conditions, coherentist justification increases the probability of truth and generates a high probability of truth. I argue that this does not follow. (shrink)

What is truth? Philosophers are interested in a range of issues involving the concept of truth beginning with what sorts of things can be true. This is a collection of eighteen new and original research papers on truth and other alethic phenomena by twenty of the most promising young scholars working on truth today.

What is truth? Michael Lynch defends a bold new answer to this question. Traditional theories of truth hold that truth has only a single uniform nature. All truths are true in the same way. More recent deflationary theories claim that truth has no nature at all; the concept of truth is of no real philosophical importance. In this concise and clearly written book, Lynch argues that we should reject both these extremes and hold that truth is a functional property. To (...) understand truth we must understand what it does, its function in our cognitive economy. Once we understand that, we'll see that this function can be performed in more than one way. And that in turn opens the door to an appealing pluralism: beliefs about the concrete physical world needn't be true in the same way as our thoughts about matters -- like morality -- where the human stain is deepest.

Truth is one of the central subjects in philosophy. It is also one of the largest. Truth has been a topic of discussion in its own right for thousands of years. Moreover, a huge variety of issues in philosophy relate to truth, either by relying on theses about truth, or implying theses about truth.

The classic and contemporary readings in this collection represent the four most influential theories of truth – correspondence, pragmatist, coherence, and deflationary theories. A collection of classic and contemporary philosophical reflections on the nature of truth. Opens with an introduction to theories of truth, designed for readers with little or no prior knowledge of the subject. Divided into four sections on the most important theories of truth - correspondence, pragmatist, coherence, and deflationary theories. Brings together articles in the recent debate (...) over the correspondence theory and deflationism that are not otherwise available in one place. Includes contributions by C.S. Peirce, William James, Bertrand Russell, Alfred Tarski, Hartry Field, Dorothy Grover, Anil Gupta and others. Concludes with an extensive bibliography of recent articles on truth. (shrink)

This paper sets out to establish that dialogue defines truth in a world of divergent cultures and worldviews. It argues that culture has enormous influence on truth for which truth through monologue has inherent strong potentials that limit intellectual union and discusses how philosophy in its western tradition has served topromote this trend with its hegemony on different world cultures; the effect of which is the quest for difference by other world cultures through cultural philosophies that attempt to infuse reason (...) and logic on their cultural achievement. The result then is an unending ambition for difference which promotes conflict of values in our world. The paper contends that truths realized in such a world is inherently deficient. It recommends dialogue as the basis for truth. Truth in a multi-cultural world would then not be the correspondence to, coherence with and pragmatic to reality but the ability to defy difference to promote the equality of difference. Bylooking at the several ways a thing could not have been for which it is an item, idea or value can then be considered to be true. (shrink)

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

In this paper, we provide a new formulation of a coherence theory of truth using the resources of the partial structures approach − in particular the notions of partial structure and quasi-truth. After developing this new formulation, we apply the resulting theory to the philosophy of mathematics, and argue that it can be used to develop a new account of nominalism in mathematics. This application illustrates the strength and usefulness of the proposed formulation of a coherence theory of truth.Neste artigo, (...) propomos uma nova formulação de uma teoria coerentista da verdade utilizando os recursos da abordagem de estruturas parciais - em particular as noções de estrutura parcial e quase-verdade.

What is the relation between coherence and truth? This paper rejects numerous answers to this question, including the following: truth is coherence; coherence is irrelevant to truth; coherence always leads to truth; coherence leads to probability, which leads to truth. I will argue that coherence of the right kind leads to at least approximate truth. The right kind is explanatory coherence, where explanation consists in describing mechanisms. We can judge that a scientific theory is progressively approximating the truth if it (...) is increasing its explanatory coherence in two key respects: broadening by explaining more phenomena and deepening by investigating layers of mechanisms. I sketch an explanation of why deepening is a good epistemic strategy and discuss the prospect of deepening knowledge in the social sciences and everyday life. (shrink)

Quine argues, in “On the Nature of Moral Values” that a coherence theory of truth is the “lot of ethics”. In this paper, I do a bit of work from within Quinean theory. Specifically, I explore precisely what a coherence theory of truth in ethics might look like and what it might imply for the study of normative value theory generally. The first section of the paper is dedicated to the exposition of a formally correct coherence truth predicate, the possibility (...) of which has been the subject of some skepticism. In the final two sections of the paper, I claim that a coherence theory in ethics does not reduce the practice of moral inquiry to absurdity, in practice as well as in principle. (shrink)

The book is a compendium of current and past thinking on the problem of understanding truth. Of course, a Correspondence Theory must be central to any such discussion. However, the author seems keenly aware that nowadays the chief rivals to Correspondence are not its substantive competitors, such as Coherence and Pragmatism, which still offer metaphysically-loaded alternatives, but rather various forms of Deflationism, including its minimalist versions. Supporters of Deflationism maintain that there is less to our understanding of the concept and/or (...) property of truth—some not even allowing that truth is a property—than is implied by any substantive treatment. And although Künne devotes a lengthy last chapter to reasons for rejecting what he calls “alethic anti-realism”, the primary focus for most of the book’s first 375 pages is in settling accounts between correspondentists and deflationists.

The author of the highly popular book Think, which Time magazine hailed as "the one book every smart person should read to understand, and even enjoy, the key questions of philosophy," Simon Blackburn is that rara avis--an eminent thinker who is able to explain philosophy to the general reader. Now Blackburn offers a tour de force exploration of what he calls "the most exciting and engaging issue in the whole of philosophy"--the age-old war over truth. The front lines of this (...) war are well defined. On one side are those who believe in plain, unvarnished facts, rock-solid truths that can be found through reason and objectivity--that science leads to truth, for instance. Their opponents mock this idea. They see the dark forces of language, culture, power, gender, class, ideology and desire--all subverting our perceptions of the world, and clouding our judgement with false notions of absolute truth. Beginning with an early skirmish in the war--when Socrates confronted the sophists in ancient Athens--Blackburn offers a penetrating look at the longstanding battle these two groups have waged, examining the philosophical battles fought by Plato, Protagoras, William James, David Hume, Hans-Georg Gadamer, Jacques Derrida, Michel Foucault, Richard Rorty, and many others, with a particularly fascinating look at Nietzsche. Among the questions Blackburn considers are: is science mere opinion, can historians understand another historical period, and indeed can one culture ever truly understand another. Blackburn concludes that both sides have merit, and that neither has exclusive ownership of truth. What is important is that, whichever side we embrace, we should know where we stand and what is to be said for our opponents. (shrink)

This application illustrates the strength and usefulness of the proposed formulation of a coherence theory of truth.

"Davidson begins by harking back to an early interest in the classics, and an even earlier engagement with the workings of grammar. In the pleasures of diagramming sentences in grade school, he locates his first glimpse into the mechanics of how we conduct the most important activities in our life - such as declaring love, asking directions, issuing orders, and telling stories. Davidson connects these essential questions with the most basic and yet hard to understand mysteries of language use - (...) how we connect noun to verb. This is a problem that Plato and Aristotle wrestled with, and Davidson draws on their thinking to show how an understanding of linguistic behavior is critical to the formulating of a workable concept of truth. Against a whole army of contemporary philosophers, Davidson argues that the concept of truth is not ambiguous.". (shrink)

It is tempting to think that, if a person's beliefs are coherent, they are also likely to be true. This truth conduciveness claim is the cornerstone of the popular coherence theory of knowledge and justification. Erik Olsson's new book is the most extensive and detailed study of coherence and probable truth to date. Setting new standards of precision and clarity, Olsson argues that the value of coherence has been widely overestimated. Provocative and readable, Against Coherence will make stimulating reading for (...) epistemologists and anyone with a serious interest in truth. (shrink)

There is an emerging consensus in the literature on probabilistic coherence that such coherence cannot be truth conducive unless the information sources providing the cohering information are individually credible and collectively independent. Furthermore, coherence can at best be truth conducive in a ceteris paribus sense. Bovens and Hartmann have argued that there cannot be any measure of coherence that is truth conducive even in this very weak sense. In this paper, I give an alternative impossibility proof. I provide a relatively (...) detailed comparison of the two results, which turn out to be logically unrelated, and argue that my result answers a question raised by Bovens and Hartmann’s study. Finally, I discuss the epistemological ramifications of these findings and try to make plausible that a shift to an explanatory framework such as Thagard’s is unlikely to turn the impossibility into a possibility.
