Scientific Realists argue that it would be a miracle if scientific theories were getting more predictive without getting closer to the truth; so they must be getting closer to the truth. Van Fraassen, Laudan et al. argue that owing to the underdetermination of theory by data (UDT) for all we know, it is a miracle, a fluke. So we should not believe in even the approximatetruth of theories. I argue that there is a test for (...) who is right: suppose we are at the limit of inquiry. Suppose that we then have all the logically possible theories that are adequate to all the actual data. If they all resembled in their theoretical claims, since one of them must be true, all of them would then resemble it, whichever it is. We would thus be justified in saying they all approximated the truth in the degree to which they co-resembled. If they don't all co-resemble, the SRs are wrong; more predictive theories are not necessarily closer to the theoretical truth. Prior to the limit, if, in spite of our best efforts to the contrary, all the theories we can make adequate to current data tend to co-resemble, we have inductive warrant for thinking more predictive theories are closer to the truth. If they don't resemble, we have inductive warrant for thinking that more predictive theories are not necessarily closer to the truth. (shrink)
This paper describes a theory of accuracy or approximatetruth and applies it to problems in the realist interpretation of scientific theories. It argues not only that realism requires approximatetruth, but that an adequate theory of approximation also presupposes some elements of a realist interpretation of theories. The paper distinguishes approximatetruth from vagueness, probability and verisimilitude, and applies it to problems of confirmation and deduction from inaccurate premises. Basic results are cited, but (...) details appear elsewhere. Objections are surveyed, including arguments by Miller, Laymon, and Laudan. Comparison is made with Niiniluoto's theory of verisimilitude, and the utility of his theory for realism assessed. (shrink)
The concept of approximatetruth plays a prominent role in most versions of scientific realism. However, adequately conceptualizing ?approximatetruth? has proved challenging. This article argues that the goal of articulating the concept of approximatetruth can be advanced by first investigating the processes by which science accords theories the status of accepted or rejected. Accordingly, this article uses a path diagram model as a visual heuristic for the purpose of showing the processes in (...) science that are involved in determining a theory's status. This ?inductive realist? model of theory status then serves as a starting point for explicating an inductive realist view of approximatetruth that, it is argued, can explain instances of the success of science, but does not (1) require science's theories to be strictly true in any world or (2) require a metric for measuring how close an approximately true theory is to some strictly true theory. To show the advantages of the inductive realist approach to approximatetruth, an example of a major success story of science, the successful eradication of smallpox, is reviewed and then explained.

There is good reason to suppose that our best physical theories, quantum mechanics and special relativity, are false if taken together and literally. If they are in fact false, then how should they count as providing knowledge of the physical world? One might imagine that, while strictly false, our best physical theories are nevertheless in some sense probably approximately true. This paper presents a notion of local probable approximatetruth in terms of descriptive nesting relations between current and (...) subsequent theories. This notion helps explain how false physical theories might nevertheless provide physical knowledge of a variety that is particularly salient to diachronic empirical inquiry. (shrink)
Arguably, there is no substantial, general answer to the question of what makes for the approximatetruth of theories. But in one class of cases, the issue seems simply resolved. A wide class of applied dynamical theories can be treated as two-component theories—one component specifying a certain kind of abstract geometrical structure, the other giving empirical application to this structure by claiming that it replicates, subject to arbitrary scaling for units etc., the geometric structure to be found in (...) some real-world dynamical phenomenon. In such a case, a theory is approximately true just if the one geometric structure approximately replicates the other (and if problems remain here, they are problems in geometry, of specifying suitable metric approximation relations, not conceptual problems). This article amplifies and defends this simple approach to approximatetruth for dynamical theories. (shrink)
I examine the role that approximatetruth plays in arguments for convergent realism and diagnose some difficulties that face attempts to defend realism by employing this slippery concept. Approximatetruth plays two important roles in convergent realism: it functions as a truth surrogate and it helps explain the success of science. I argue that approximatetruth cannot perform both of these roles. If it adequately fulfills its role as a (...) class='Hi'>truth surrogate, then it cannot explain the success of science. If it adequately explains the success of science, then it cannot function as a truth surrogate. (shrink)
In this paper I show that Goodman's theory of projectibility, although partly successful, is inadequate since it fails to take into consideration the "approximate" nature of certain scientific hypotheses.
The example can be generalized. Suppose that ϕ and ψ are suffi- ciently different functions of an independent variable t. We may show that whenever X’s predictions for ϕ and ψ lie (weakly) between Z’s predictions and T’s predictions (the true values), then there are other quantities, interdefinable with ϕ and ψ, that reverse the ordering.
We investigate the logical and conceptual connections between abductive reasoning construed as a process of belief change, on the one hand, and truth approximation, construed as increasing (estimated) verisimilitude, on the other. We introduce the notion of â(verisimilitude-guided) abductive belief changeâ and discuss under what conditions abductively changing our theories or beliefs does lead them closer to the truth, and hence tracks truth approximation conceived as the main aim of inquiry. The consequences of our analysis for some (...) recent discussions concerning belief revision aiming at truth approximation and inference to the best explanation are also highlighted. (shrink)
Recently a number of variously motivated epistemologists have argued that knowledge is closely tied to practical matters. On the one hand, radical pragmatic encroachment is the view that facts about whether an agent has knowledge depend on practical factors and this is coupled to the view that there is an important connection between knowledge and action. On the other hand, one can argue for the less radical thesis only that there is an important connection between knowledge and practical reasoning. So, (...) defenders of both of these views endorse the view that knowledge is the norm of practical reasoning. This thesis has recently come under heavy fire and a number of weaker proposals have been defended. In this paper counter-examples to the knowledge norm of reasoning will be presented and it will be argued that this viewand a number of related but weaker viewscannot be sustained in the face of these counter-examples. The paper concludes with a novel proposal concerning the norm of practical reasoning that is immune to the counter-examples introduced here. (shrink)
I present a new definition of verisimilitude, framed in terms of causes. Roughly speaking, according to it a scientific model is approximately true if it captures accurately the strengths of the causes present in any given situation. Against much of the literature, I argue that any satisfactory account of verisimilitude must inevitably restrict its judgments to context-specific models rather than general theories. We may still endorse—and only need—a relativized notion of scientific progress, understood now not as global advance but rather (...) as the mastering of particular problems. This also sheds new light on longstanding difficulties surrounding language-dependence and models committed to false ontologies. (shrink)
This paper challenges Williamson's "E = K" thesis on the basis of evidential practice. The main point is that most evidence is only approximately true and so cannot be known if knowledge is factive.
What attitude should we take toward a scientific theory when it competes with other scientific theories? This question elicited different answers from instrumentalists, logical positivists, constructive empiricists, scientific realists, holists, theory-ladenists, antidivisionists, falsificationists, and anarchists in the philosophy of science literature. I will summarize the diverse philosophical responses to the problem of underdetermination, and argue that there are different kinds of underdetermination, and that they should be kept apart from each other because they call for different responses.
In this paper Timothy Williamson’s argument that the knowledge norm of assertion is the best explanation of the unassertability of Morrean sentences is challenged and an alternative account of the norm of assertion is defended.
We provide a 'verisimilitudinarian' analysis of the well-known Linda paradox or conjunction fallacy, i.e., the fact that most people judge the probability of the conjunctive statement "Linda is a bank teller and is active in the feminist movement" (B & F) as more probable than the isolated statement "Linda is a bank teller" (B), contrary to an uncontroversial principle of probability theory. The basic idea is that experimental participants may judge B & F a better hypothesis about Linda as compared (...) to B because they evaluate B & F as more verisimilar than B. In fact, the hypothesis "feminist bank teller", while less likely to be true than "bank teller", may well be a better approximation to the truth about Linda. (shrink)
Truth in the Making represents a sophisticated effort to map the complex relations between human knowledge and creative power, as reflected across more than half a millennium of philosophical enquiry. Showing the intimacy of this problematic to the work of Nicholas of Cusa, Bacon, Galileo, Descartes, Hobbes, Leibniz, Vico and David Lachterman, the book reveals how questions about creation apparently diluted by secularism in fact retain much of their potency today. If science could counterfeit or synthesize nature precisely from (...) its smallest nuts and bolts, as Descartes and Hobbes implied and as modern science increasingly suggests, would it create an identical world to that we live in now Robert C. Miner offers a precise genealogy of modern thought on truth and creation: from medieval theology's identification of human creativity with divine initiative to the radical Leibnizian contention that human ideas are 'not little copies of God's', and may at once exceed mimesis and produce things new, unpredictable and unseen. He considers how the theological importance given to creation interacts historically with the secularisation and instrumentalisation of modes of discovery and method, and asks how knowledge is understood between different disciplines, from the allegorical discipline of poetry to the constructible field of mathematics. The book is an eloquent reminder of the ways in which theology continues to fling a wild card at philosophical understandings of reality, countering theories of metaphysical equivalence of the 'real' and 'artificial' with theologies in which human making is always fallible, and strives only for approximate participation in divine truth. As a strenuous and informative breakdown of leading theories of knowledge, Truth in the Making shows the continuing influence of theological questions upon philosophical, scientific and aesthetic disciplines, whilst raising topical questions about the ultimate nature of our reality and our freedom to modify and define it.

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 approximatetruth. 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)
Realists regarding scientific knowledge – those who think that our best scientific representations truly describe both observable and unobservable aspects of the natural world – have special need of a notion of approximatetruth. Since theories and models are rarely considered true simpliciter, the realist requires some means of making sense of the claim that they may be false and yet close to the truth, and increasingly so over time. In this paper, I suggest that traditional approaches (...) to approximatetruth are insensitive to two crucial features of scientific knowledge, and that for each of these, analogies between representational practices in the sciences and in art prove useful to understanding how this situation can be remedied. First, I outline two distinct ways in which representations deviate from the truth, commonly referred to as ‘abstraction’ and ‘idealization’. Second, I argue that these practices exemplify different conventions of representation, and that for each, the conditions of approximation relevant to explicating the concept of approximatetruth must be understood differently. The concept is thus heterogeneous; approximatetruth is a virtue that is multiply realized, relative to different contexts of representation. This understanding is facilitated, I suggest, by considering the distinction between realistic and non-realistic representation in art. (shrink)
In this paper it is argued that the theory of truth approximation should be pursued in the framework of some kind of geometry of logic. More specifically it is shown that the theory of interval structures provides a general framework for dealing with matters of truth approximation. The qualitative and the quantitative accounts of truthlikeness turn out to be special cases of the interval account. This suggests that there is no principled gap between the qualitative and quantitative approach. (...) Rather, there is a connected spectrum of ways of measuring truthlikeness depending on the specifics of the context in which it takes place. (shrink)
Three related intuitions are explicated in this paper. The first is the idea that there must be some kind of probabilistic version of the HD-method, a ‘Hypothetico-Probabilistic (HP-) method’, in terms of something like probabilistic consequences, instead of deductive consequences. According to the second intuition, the comparative application of this method should also be functional for some probabilistic kind of empirical progress, and according to the third intuition this should be functional for something like probabilistic truth approximation. In all (...) three cases, the guiding idea is to explicate these intuitions by explicating the crucial notions as appropriate ‘concretizations’ of their deductive analogs, being ‘idealizations’. It turns out that the comparative version of the proposed HP-method amounts to the likelihood comparison (LC-) method applied to the cumulated evidence. This method turns out to be not only functional for probabilistic empirical progress but also for probabilistic truth approximation. The latter is based on a probabilistic threshold theorem constituting for this reason the analog of the deductive success theorem. (shrink)
Surprisingly enough, modified versions of the confirmation theory of Carnap and Hempel and the truth approximation theory of Popper turn out to be smoothly synthesizable. The glue between confirmation and truth approximation appears to be the instrumentalist methodology, rather than the falsificationist one.By evaluating theories separately and comparatively in terms of their successes and problems (hence even if they are already falsified), the instrumentalist methodology provides – both in theory and in practice – the straight route for short-term (...) empirical progress in science in the spirit of Laudan. However, it is argued that such progress is also functional for all kinds of truth approximation: observational, referential, and theoretical. This sheds new light on the long-term dynamic of science and hence on the relation between the main epistemological positions, viz., instrumentalism (Toulmin, Laudan), constructive empiricism (van Fraassen), referential realism (Hacking and Cartwright), and theory realism of a non-essentialist nature (Popper), here called constructive realism.In From Instrumentalism to Constructive Realism (2000) the above story is presented in great detail. The present synopsis highlights the main ways of theory evaluation presented in that book, viz. evaluation in terms of confirmation (or falsification), empirical progress and truth approximation.

Approximations form an essential part of scientific activity and they come in different forms: conceptual approximations (simplifications in models), mathematical approximations of various types (e.g. linear equations instead of non-linear ones, computational approximations), experimental approximations due to limitations of the instruments and so on and so forth. In this paper, we will consider one type of approximation, namely numerical approximations involved in the comparison of two results, be they experimental or theoretical. Our goal is to lay down the conceptual and (...) formal foundations of a local theory of partial truth. This is done by introducing and exploring the concept of truth space. (shrink)
Humans lie and deceive themselves, and often choose beliefs for reasons other than how closely those beliefs approximatetruth. This is mainly why we disagree. Three future trends may reduce these epistemic vices. First, increased documentation and surveillance should make it harder to lie and self-deceive about the patterns of our lives. Second, speculative markets can create a relatively unbiased consensus on most debated topics in science, business, and policy. Third, brain modifications may allow our minds to be (...) more transparent, so that lies and self-deception become harder to hide. In evaluating these trends, we should be wary of moral arrogance. (shrink)
D. Miller's demonstrations of the language dependence of truthlikeness raise a profound problem for the claim that scientific progress is objective. In two recent papers (Barnes 1990, 1991) I argue that the objectivity of progress may be grounded on the claim that the aim of science is not merely truth but knowledge; progress thus construed is objective in an epistemic sense. In this paper I construct a new solution to Miller's problem grounded on the notion of "approximate causal (...) explanation" which allows for linguistically invariant progress outside an epistemic context. I suggest that the notion of "approximate causal explanation" provides the resources for a more robust theory of progress than that provided by the notion of "approximatetruth.". (shrink)
This paper primarily deals with the conceptual prospects for generalizing the aim of abduction from the standard one of explaining surprising or anomalous observations to that of empirical progress or even truth approximation. It turns out that the main abduction task then becomes the instrumentalist task of theory revision aiming at an empirically more successful theory, relative to the available data, but not necessarily compatible with them. The rest, that is, genuine empirical progress as well as observational, referential and (...) theoretical truth approximation, is a matter of evaluation and selection, and possibly new generation tasks for further improvement. The paper concludes with a survey of possible points of departure, in AI and logic, for computational treatment of the instrumentalist task guided by the ‘comparative evaluation matrix’. (shrink)
The main formal notion involved in qualitative truth approximation by the HD-method, viz. ‘more truthlike’, is shown to not only have, by its definition, an intuitively appealing ‘model foundation’, but also, at least partially, a conceptually plausible ‘consequence foundation’. Moreover, combining the relevant parts of both leads to a very appealing ‘dual foundation’, the more so since the relevant methodological notions, viz. ‘more successful’ and its ingredients provided by the HD-method, can be given a similar dual foundation. According to (...) the resulting dual foundation of ‘naive truth approximation’, the HD-method provides successes (established true consequences) and counterexamples (established wrongly missing models) of theories. Such HD-results may support the tentative conclusion that one theory seems to remain more successful than another in the naive sense of having more successes and fewer counterexamples. If so, this provides good reasons for believing that the more successful theory is also more truthlike in the naive sense of having more correct models and more true consequences. (shrink)
When talking about truth, we ordinarily take ourselves to be talking about one-and-the-same thing. Alethic monists suggest that theorizing about truth ought to begin with this default or pre-reflective stance, and, subsequently, parlay it into a set of theoretical principles that are aptly summarized by the thesis that truth is one. Foremost among them is the invariance principle.
This takes a closer look at the actual semantic behavior of apparent truth predicates in English and re-evaluates the way they could motivate particular philosophical views regarding the formal status of 'truth predicates' and their semantics. The paper distinguishes two types of 'truth predicates' and proposes semantic analyses that better reflect the linguistic facts. These analyses match particular independently motivated philosophical views.
Common-sense allows that talk about moral truths makes perfect sense. If you object to the United States’ Declaration of Independence’s assertion that it is a truth that ‘all men’ are ‘endowed by their Creator with certain unalienable Rights’, you are more likely to object that these rights are not unalienable or that they are not endowed by the Creator, or even that its wording ignores the fact that women have rights too, than that this is not the sort of (...) thing which could be a truth. Whether it is a truth or not seems beside the point, anyway; the writers of the Declaration could just have well written, ‘We hold it to be self-evident that all men are created equal, and also that it is self-evident that all men are endowed by their Creator with certain unalienable Rights,’ save only that its cadence would lack some of the poetic resonance of the version which garnered Hancock’s signature. Yet famously, ethical noncognitivists have proclaimed that moral sentences can’t be true or false – that, like ‘Hooray!’ or ‘dammit!’, they are not even the kinds of things to be true or false. Noncognitivism is sometimes even defined as the view that this is so, but even philosophers who define ‘noncognitivism’ more broadly, as consistent with the idea that moral sentences may be true or false, have believed that they needed to do important philosophical spadework in order to make sense of how moral sentences could be true or false. In this article we’ll look at the puzzle about moral truth as it is faced by early noncognitivists and by metaethical expressivists, the early noncognitivists’ contemporary cousins. We’ll look at what it would take for expressivists to ‘earn the right’ to talk about moral truths at all, and in particular at what it would take for them to earn the right to claim that moral truths behave in the ways that we should expect – including that meaningful moral sentences which lack presuppositions are true or false, and that classically valid arguments are truth-preserving..

Attention to the conversational role of alethic terms seems to dominate, and even sometimes exhaust, many contemporary analyses of the nature of truth. Yet, because truth plays a role in judgment and assertion regardless of whether alethic terms are expressly used, such analyses cannot be comprehensive or fully adequate. A more general analysis of the nature of truth is therefore required – one which continues to explain the significance of truth independently of the role alethic terms (...) play in discourse. We undertake such an analysis in this paper; in particular, we start with certain elements from Kant and Frege, and develop a construct of truth as a normative modality of cognitive acts (e.g., thought, judgment, assertion). Using the various biconditional T-schemas to sanction the general passage from assertions to (equivalent) assertions of truth, we then suggest that an illocutionary analysis of truth can contribute to its locutionary analysis as well, including the analysis of diverse constructions involving alethic terms that have been largely overlooked in the philosophical literature. Finally, we briefly indicate the importance of distinguishing between alethic and epistemic modalities. (shrink)
We say that a sentence A is a permissive consequence of a set of premises Gamma whenever, if all the premises of Gamma hold up to some standard, then A holds to some weaker stan- dard. In this paper, we focus on a three-valued version of this notion, which we call strict-to-tolerant consequence, and discuss its fruitfulness toward a uni ed treatment of the paradoxes of vagueness and self-referential truth. For vagueness, st-consequence supports the principle of tolerance; for (...) class='Hi'>truth, it supports the requisit of transparency. Permissive consequence is non-transitive, however, but this feature is argued to be an essential component to the understanding of paradoxical reasoning in cases involving vagueness or self-reference. .

The revisionary approach to semantic paradox is commonly thought to have a somewhat uncomfortable corollary, viz. that, on pain of triviality, we cannot affirm that all valid arguments preserve truth (Beall2007, Beall2009, Field2008, Field2009). We show that the standard arguments for this conclusion all break down once (i) the structural rule of contraction is restricted and (ii) how the premises can be aggregated---so that they can be said to jointly entail a given conclusion---is appropriately understood. In addition, we briefly (...) rehearse some reasons for restricting structural contraction. (shrink)
This paper utilizes Scott domains (continuous lattices) to provide a mathematical model for the use of idealized and approximately true data in the testing of scientific theories. Key episodes from the history of science can be understood in terms of this model as attempts to demonstrate that theories are monotonic, that is, yield better predictions when fed better or more realistic data. However, as we show, monotonicity and truth of theories are independent notions. A formal description is given of (...) the pragmatic virtues of theories which are monotonic. We also introduce the stronger concept of continuity and show how it relates to the finite nature of scientific computations. Finally, we show that the space of theories also has the structure of a Scott domain. This result provides an analysis of how one theory can be said to approximate another. (shrink)
This short paper about fuzzy set-based approximate reasoning first emphasizes the three main semantics for fuzzy sets: similarity, preference and uncertainty. The difference between truth-functional many-valued logics of vague or gradual propositions and non fully compositional calculi such as possibilistic logic (which handles uncertainty) or similarity logics is stressed. Then, potentials of fuzzy set-based reasoning methods are briefly outlined for various kinds of approximate reasoning: deductive reasoning about flexible constraints, reasoning under uncertainty and inconsistency, hypothetical reasoning, exception-tolerant (...) plausible reasoning using generic knowledge, interpolative reasoning, and abductive reasoning (under uncertainty). Open problems are listed in the conclusion. (shrink)
Aspects of a formal theory of approximate generalizations, according to which they have degrees of truth measurable by the proportions of their instances for which they are true, are discussed. The idealizability of laws in theories of fundamental measurement is considered: given that the laws of these theories are only approximately true "in the real world", does it follow that slight changes in the extensions of their predicates would make them exactly true?

I offer a new theory of faultless disagreement, according to which truth is absolute (non-relative) but can still be non-objective. What's relative is truth-aptness: a sentence like ‘Vegemite is tasty’ (V) can be truth-accessible and bivalent in one context but not in another. Within a context in which V fails to be bivalent, we can affirm that there is no issue of truth or falsity about V, still disputants, affirming and denying V, were not at fault, (...) since, in their context of assertion V was bivalent. This theory requires a theory of assertion that is a form of cognitive expressivism. (shrink)
Minimalism is currently the received deflationary theory of truth. On minimalism, truth is a transparent concept and a deflated property of truth bearers. In this paper, I situate minimalism within current deflationary debate about truth by contrasting it with its main alternative―the redundancy theory of truth (according to which truth is a transparent concept but not a property). I also outline three of the primary challenges facing minimalism, its formulation, explanatory adequacy and stability, and (...) draw some lessons for the soundness of its conception of truth.

My goal is to illuminate truth-making by way of illuminating the relation of making. My strategy is not to ask what making is, in the hope of a metaphysical theory about is nature. It's rather to look first to the language of making. The metaphor behind making refers to agency. It would be absurd to suggest that claims about making are claims about agency. It is not absurd, however, to propose that the concept of making somehow emerges from some (...) feature to do with agency. That's the contention to be explore in this paper. The way to do this is through expressivism,. Truth-making claims, and making-claims generfally, are claims in which we express mental states linked to our maipulation of concepts, like truth. In particular, they express disposition to undertake derivations using inference rules, in which introduction rules have a specific role. I then show how this theory explains our intuitions about truth's asymmetric dependence on being. (shrink)
Fiction is often characterized by way of a contrast with truth, as, for example, in the familiar couplet “Truth is always strange/ Stranger than fiction" (Byron 1824). And yet, those who would maintain that “we will always learn more about human life and human personality from novels than from scientific psychology” (Chomsky 1988: 159) hold that some truth is best encountered via fiction. The scrupulous novelist points out that her work depicts no actual person, either living or (...) dead; nonetheless, we use names from fiction in ways that suggest that we take these names to refer. Philosophers who investigate fiction aim to reconcile such apparently incompatible phenomena, and, in general, to account for the myriad ways that we talk, think, and feel about fiction. (shrink)
Now in a new edition, this volume updates Davidson's exceptional Inquiries into Truth and Interpretation (1984), which set out his enormously influential philosophy of language.

This paper is a reply to Michael Lynch's "Truth, Value and Epistemic Expressivism" in Philosophy and Phenomenological Research for 2009. It argues that Lynch's argument against expressivism fails because of an ambiguity in the employed notion of an 'epistemically disengaged standpoint'.
Relativism has dominated many intellectual circles, past and present, but the twentieth century saw it banished to the fringes of mainstream analytic philosophy. Of late, however, it is making something of a comeback within that loosely configured tradition, a comeback that attempts to capitalize on some important ideas in foundational semantics. Relativism and Monadic Truth aims not merely to combat analytic relativism but also to combat the foundational ideas in semantics that led to its revival. Doing so requires a (...) proper understanding of the significance of possible worlds semantics, an examination of the relation between truth and the flow of time, an account of putatively relevant data from attitude and speech act reporting, and a careful treatment of various operators. Throughout, Herman Cappelen and John Hawthorne contrast relativism with a view according to which the contents of thought and talk are propositions that instantiate the fundamental monadic properties of truth simpliciter and falsity simpliciter. Such propositions, they argue, are the semantic values of sentences (relative to context), the objects of illocutionary acts, and, unsurprisingly, the objects of propositional attitudes. (shrink)

Truths are determined not by what we believe, but by the way the world is. Or so realists about truth believe. Philosophers call such theories correspondence theories of truth. Truthmaking theory, which now has many adherents among contemporary philosophers, is the most recent development of a realist theory of truth, and in this book D. M. Armstrong offers the first full-length study of this theory. He examines its applications to different sorts of truth, including contingent truths, (...) modal truths, truths about the past and the future, and mathematical truths. In a clear, even-handed and non-technical discussion he makes a compelling case for truthmaking and its importance in philosophy. His book marks a significant contribution to the debate and will be of interest to a wide range of readers working in analytical philosophy. (shrink)
Truth, etc. is a wide-ranging study of ancient logic based upon the John Locke lectures given by the eminent philosopher Jonathan Barnes in Oxford. The book presupposes no knowledge of logic and no skill in ancient languages: all ancient texts are cited in English translation; and logical symbols and logical jargon are avoided so far as possible. Anyone interested in ancient philosophy, or in logic and its history, will find much to learn and enjoy here.

What is truth. Paul Horwich advocates the controversial theory of minimalism, that is that the nature of truth is entirely captured in the trivial fact that each proposition specifies its own condition for being true, and that truth is therefore an entirely mundane and unpuzzling concept. The first edition of Truth, published in 1980, established itself as the best account of minimalism and as an excellent introduction to the debate for students. For this new edition, Horwich (...) has refined and developed his treatment of the subject in the light of subsequent discussions, while preserving the distinctive format that made the earlier edition so successful.

Postmodernists claim that there is no truth. However, the statement 'there is no truth' is self-contradictory. This essay shows the following: One cannot state the idea 'there is no truth' universally without creating a paradox. In contrast, the statement 'there is truth' does not produce such a paradox. Therefore, it is more logical that truth exists.
This paper presents an account of the manner in which a proposition’s immediate structural features are related to its core truth-conditional features. The leading idea is that for a proposition to have a certain immediate structure is just for certain entities to play certain roles in the correct theory of the brute facts regarding that proposition’s truth conditions. The paper explains how this account addresses certain worries and questions recently raised by Jeffery King and Scott Soames.
A popular account of epistemic justification holds that justification, in essence, aims at truth. An influential objection against this account points out that it is committed to holding that only true beliefs could be justified, which most epistemologists regard as sufficient reason to reject the account. In this paper I defend the view that epistemic justification aims at truth, not by denying that it is committed to epistemic justification being factive, but by showing that, when we focus on (...) the relevant sense of ‘justification’, it isn’t in fact possible for a belief to be at once justified and false. To this end, I consider and reject three popular intuitions speaking in favor of the possibility of justified false beliefs, and show that a factive account of epistemic justification is less detrimental to our normal belief forming practices than often supposed.

It is common to hear talk of the aim of belief and to find philosophers appealing to that aim for numerous explanatory purposes. What belief's aim explains depends, of course, on what that aim is. Many hold that it is somehow related to truth, but there are various ways in which one might specify belief's aim using the notion of truth. In this article, by considering whether they can account for belief's standard of correctness and the epistemic norms (...) governing belief, I argue against certain prominent specifications of belief's aim given in terms of truth, and advance a neglected alternative.

That truth provides the standard for believing appears to be a platitude, one which dovetails with the idea that in some sense belief aims only at the truth. In recent years, however, an increasing number of prominent philosophers have suggested that knowledge provides the standard for believing, and so that belief aims only at knowledge. In this paper, I examine the considerations which have been put forward in support of this suggestion, considerations relating to lottery beliefs, Moorean beliefs, (...) the criticism and defence of belief, and the value of knowledge. I argue that those considerations do not give us reason to give up the truth view in favour of the knowledge view and, moreover, that reflection on those considerations gives us some reason to reject the knowledge view. Thus, I conclude, we can continue to the take the apparent platitude at face value. (shrink)
In recent work on contextdependency, it has been argued that certain types of sentences give rise to a notion of relative truth. In particular, sentences containing predicates of personal taste and moral or aesthetic evaluation as well as epistemic modals are held to express a proposition (relative to a context of use) which is true or false not only relative to a world of evaluation, but other parameters as well, such as standards of taste or knowledge or an agent. (...) Thus, a sentence like chocolate tastes good would express a proposition p that is true or false not only at a world of evaluation, but relative to the additional parameter as well, such as a parameter of taste or an agent. I will argue that the sentences that apparently give rise to relative truth should be understood by relating them in a certain way to the first person. More precisely, such sentences express what I will call firstpersonbased genericity, a form of generalization that is based on or directed toward an essential firstperson application of the predicate. The account differs from standard relative truth account in crucial respects: it is not the truth of the proposition expressed that is relative to the first person; the proposition expressed by a sentence with a predicate of taste rather has absolute truth conditions. Instead it is the propositional content itself that requires a firstpersonal cognitive access whenever it is entertained. This account, I will argue, avoids a range of problems that standard relative truth theories of the sentences in question face and explains a number of further peculiarities that such sentences display.

I argue that conventional implicatures embed in logical compounds, and are non-truth-conditional contributors to sentence meaning. This, I argue has significant implications for how we understand truth, truth-conditional content, and truth-bearers.
In this ingenious and powerfully argued book Tim Maudlin sets out a novel account of logic and semantics which allows him to deal with certain notorious paradoxes which have bedevilled philosophical theories of truth. All philosophers interested in logic and language will find this a stimulating read.
Kant claims that the nominal definition of truth is: “Truth is the agreement of cognition with its object”. In this paper, I analyse the relevant features of Kant's theory of definition in order to explain the meaning of that claim and its consequences for the vexed question of whether Kant endorses or rejects a correspondence theory of truth. I conclude that Kant's claim implies neither that he holds, nor that he rejects, a correspondence theory of truth. (...) Kant's claim is not a generic way of setting aside a correspondence definition of truth, or of considering it uninformative. Being the nominal definition of truth, the formula “truth is the agreement of cognition with its object” illustrates the meaning of the predicate “is true” and people's ordinary conception of truth. True judgements correspond to the objects they are about. However, there could be more to the property of truth than correspondence. (shrink)

In the Pre-Qin time, pursuing “Dao” was the main task in the scholarship of most of the ancient Chinese philosophers, while the Ancient Greek philosophers considered pursuing “Truth” as their ultimate goal. While the “Dao” in ancient Chinese texts and the “Truth” in ancient Greek philosophic literature do share or cross-cover certain connotations, there are subtle and important differences between the two comparable philosophic concepts. These differences have deep and profound impact on the later development of Chinese and (...) Western philosophy and culture respectively. Interestingly, while the modern Chinese philosophy has gradually accepted and established the Western conception of “Truth” on its way towards modernization, the “post-modern” Western philosophy is just undergoing a process of deconstructing its traditional concept of “Truth”, thus, in a certain sense, going closer to the traditional Chinese “Dao”. From a comparative, relative and dynamic perspective, there could possibly be a fusion of horizon between the Chinese “Dao” and the Western “Truth”. (shrink)
Constructive empiricists claim to offer a reconstruction of the aim and practice of science without adopting all the metaphysical commitments of scientific realism. Deflationists about truth boast of the ability to offer a full account of the nature of truth without adopting the metaphysical commitments accompanying substantive accounts. Though the two views would form an attractive package, I argue that the pairing is not possible: constructive empiricism requires a substantive account of truth. I articulate what sort of (...) account of truth and empirical adequacy the constructive empiricist must offer and then show why deflationists cannot uphold such an account. (shrink)
In this paper, we defend Davidson's program in truth-theoretical semantics against recent criticisms by Scott Soames. We argue that Soames has misunderstood Davidson's project, that in consequence his criticisms miss the mark, that appeal to meanings as entities in the alternative approach that Soames favors does no work, and that the approach is no advance over truth-theoretic semantics.
I want to discuss a puzzle about the semantics of epistemic modals, like “It might be the case that” as it occurs in “It might be the case that Goldbach’s conjecture is false.”1 I’ll argue that the puzzle cannot be adequately explained on standard accounts of the semantics of epistemic modals, and that a proper solution requires relativizing utterance truth to a context of assessment, a semantic device whose utility and coherence I have defended elsewhere for future contingents (MacFarlane..
Draft for Martinich and Hoekstra (ed.), Oxford Handbook of Hobbes. -/- Language was central to Hobbes's understanding of human beings and their mental abilities, and criticism of other philosophers' uses of language became a favorite critical tool for him. This paper connects Hobbes's theories about language to his criticisms of others' language, examining Hobbes's theories of propositions and truth, and how they relate to his claims that various sorts of proposition are absurd. It considers whether Hobbes in fact means (...) anything more by 'absurd' than 'false'. And it pays particular attention to Hobbes's categorization of causes of absurdity and of types of incoherent proposition, arguing that Hobbes's approach is only loosely related to later discussions of category mistakes.

The paper argues for the applicability of the notion of collective truth as opposed to distributive truth, that is, truth at times or possibilia taken in groups rather than individually. The underlying reasoning is that there are transtemporal and transworld relationships, e.g., those involving the relations of <being a descendant of> and <thinking about>. Relationships are (one type of) truth-makers. Hence, there are transtemporal and transworld truth-makers. Therefore, there is transtemporal and transworld truth, i.e., (...) collective truth. A semantics is developed (formalized in the appendix) which embodies the notion of collective truth, and which thereby, it is argued, has various advantages over standard intensional semantics. For example, it avoids a commitment to certain impossible entities. (shrink)
It is almost universally presumed that knowledge is factive: in order to know that p it must be the case that p is true. This idea is often justified by appealing to knowledge ascriptions and related linguistic phenomena; i.e., an utterance of the form ‘S knows that p, but not-p’ sounds contradictory. In a recent article, Allan Hazlett argues that our ordinary concept of knowledge is not factive. From this it seems to follow that epistemologists cannot appeal to ordinary language (...) to justify the truth condition of knowledge. More significantly, Hazlett claims that epistemologists theorizing about knowledge should not concern themselves with the ordinary concept of knowledge as revealed by knowledge ascriptions and related linguistic phenomena. My paper has two goals: first, to defend the orthodox view that the ordinary concept of knowledge is factive; second, to undermine Hazlett’s claim that epistemologists should not theorize about knowledge on the basis of how ‘knows’ is used in everyday speech.

In this paper I will be concerned with the question as to whether expressivist theories of meaning can coherently be combined with deflationist theories of truth. After outlining what I take expressivism to be and what I take deflationism about truth to be, I’ll explain why I don’t take the general version of this question to be very hard, and why the answer is ‘yes’. Having settled that, I’ll move on to what I take to be a more (...) pressing and interesting version of the question, arising from a prima facie tension between deflationism about truth and the motivations underlying expressivism for what I take to be two of its most promising applications: to indicative conditionals and epistemic modals. Here I’ll argue that the challenge is substantive, but that there is no conceptual obstacle to its being met, provided that one’s expressivism takes the right form. (shrink)
"Much truth is spoken, that more may be concealed," wrote Mr. Justice Darling in 1879. Opening with an articulation of the distinction between truth (the concept) and truths (particular true propositions), this paper is largely devoted to: -/- (1) developing an account of the dual meaning of "partially true" - "true-in-part" vs. "part of the truth"; and -/- (2) understanding the reasons for, and the dangers of, the very common tendency to tell only part of the relevant (...)truth.

Friedrich Nietzsche haunts the modern world. His elusive writings with their characteristic combination of trenchant analysis of the modern predicament and suggestive but ambiguous proposals for dealing with it have fascinated generations of artists, scholars, critics, philosophers, and ordinary readers. Maudemarie Clark's highly original study gives a lucid and penetrating analytical account of all the central topics of Nietzsche's epistemology and metaphysics, including his views on truth and language, his perspectivism, and his doctrines of the will-to-power and the eternal (...) recurrence. The Nietzsche who emerges from these pages is a subtle and sophisticated philosopher, whose highly articulated views are of continuing interest as contributions to a whole range of philosphical issues. This remarkable reading of Nietzsche will interest not only philosophers, but also readers in neighboring disciplines such as literature and intellectual history. (shrink)
In this paper, I take issue with an idea that has emerged from recent relativist proposals, and, in particular, from Lasersohn (Linguistics and Philosophy 28: 643–686, 2005), according to which the correct semantics for taste predicates must use contents that are functions of a judge parameter (in addition to a possible world parameter) rather than implicit arguments lexically associated with such predicates. I argue that the relativist account and the contextualist implicit argument-account are, from the viewpoint of semantics, not much (...) more than notational variants of one another. In other words, given any sentence containing a taste predicate, and given any assignment of values to the relevant parameters, the two accounts predict the same truth value and are, in that sense, equivalent. I also look at possible reasons for preferring one account over the other. The phenomenon of “faultless disagreement” (cf. Kölbel, Truth without objectivity, 2002) is often believed to be one such reason. I argue, against Kölbel and Lasersohn, that disagreement is never faultless: either the two parties genuinely disagree, hence if the one is right then the other is wrong, or the two parties are both right, but their apparent disagreement boils down to a misunderstanding. What is more, even if there were faultless disagreement, I argue that relativism would fail to account for it. The upshot of my paper, then, is to show that there is not much disagreement between a contextualist account that models the judge parameter as an implicit argument to the taste predicate, and a relativist account that models it as a parameter of the circumstances of evaluation. The choice between the two accounts, at least when talking about taste, is thus, to a large extent, a matter of taste. (shrink)
I argue that there is no metaphysically substantive property of truth. Although many take this thesis to be central to deflationism about truth, it is sometimes left unclear what a metaphysically substantive property of truth is supposed to be. I offer a precise account by relying on the distinction between the property and concept of truth. Metaphysical substantivism is the view that the property of truth is a sparse (non-abundant) property, regardless of how one understands (...) the nature of sparse properties (as universals, tropes, or natural classes). I then offer two new arguments against metaphysical substantivism that employ ideas involving recombination and truthmaking. First, I argue that there are no theoretically compelling reasons to posit the existence of a metaphysically substantive property of truth. Secondly, I argue that if we do posit the existence of such a property, then we end up with a view that is either contradictory or unmotivated. What we’re left with is a metaphysically deflationary account of the property of truth that fully respects the metaphysical ambitions of truthmaker theory, and that is consistent with both the view that truth is a deflated, explanatorily impotent concept and the view that truth is an explanatorily powerful (though primitive) concept.

Abstract. The aim of this paper is first to defend the intuition that truth is grounded in how things are and, second, to argue that this fact is consistent with Minimalism. After having cashed out that intuition in terms of explanatory claims of the form ‘if it is true that p, it is true that p because p’, I set out an argument against Minimalism which is based on the same intuition, and I argue that a strategy the minimalist (...) could adopt to resist the argument, i.e. to deny the correctness of the intuition, is flawed. Then I explain why the intuition is correct and I make some claims concerning the kind of explanations which are involved in it. Now the stage is set up to present the right way for the minimalist to resist the argument. I finally answer some objections. (shrink)
Ernst Cassirer claimed that Kant's notion of actual object presupposes the notion of truth. Therefore, Kant cannot define truth as the correspondence of a judgement with an actual object. In this paper, I discuss the relations between Kant's notions of truth, object, and actuality. I argue that's notion of actual object does not presuppose the notion of truth. I conclude that Kant can define truth as the correspondence of a judgement with an actual object.
Bernard Williams has argued that, because belief aims at getting the truth right, it is a conceptual truth that we cannot directly will to believe. Manyothers have adopted Williams claim that believers necessarily respect truth-conducive reasons and evidence. By presenting increasingly stronger cases, I argue that, on the contrary, believers can quite consciously disregard the demand for truth-conducive reasons and evidence. The irrationality of those who would directly will to believe is not any greater than that (...) displayed by some actual believers. So, our inability to directly will to believe is a contingent truth (at best). (shrink)
Marian David defends the correspondence theory of truth against the disquotational theory of truth, its current major rival. The correspondence theory asserts that truth is a philosophically rich and profound notion in need of serious explanation. Disquotationalists offer a radically deflationary account inspired by Tarski and propagated by Quine and others. They reject the correspondence theory, insist truth is anemic, and advance an "anti-theory" of truth that is essentially a collection of platitudes: "Snow is white" (...) is true if and only if snow is white; "Grass is green" is true if and only if grass is green. According to disquotationalists the only profound insight about truth is that it lacks profundity. David contrasts the correspondence theory with disquotationalism and then develops the latter position in rich detail--more than has been available in previous literature--to show its faults. He demonstrates that disquotationalism is not a tenable theory of truth, as it has too many absurd consequences. (shrink)
Dialetheism is the view that some contradictions are true. This is a view which runs against orthodoxy in logic and metaphysics since Aristotle, and has implications for many of the core notions of philosophy. Doubt Truth to Be a Liar explores these implications for truth, rationality, negation, and the nature of logic, and develops further the defense of dialetheism first mounted in Priest's In Contradiction, a second edition of which is also available.

This work presents a version of the correspondence theory of truth based on Wittgenstein's Tractatus and Russell's theory of truth and discusses related metaphysical issues such as predication, facts, and propositions. Like Russell and one prominent interpretation of the Tractatus it assumes a realist view of universals. Part of the aim is to avoid Platonic propositions, and although sympathy with facts is maintained in the early chapters, the book argues that facts as real entities are not (...) needed. It includes discussion of contemporary philosophers such as David Armstrong, William Alston, and Paul Horwich, as well as those who write about propositions and facts, and a number of recent students of Bertrand Russell. It will interest teachers and advanced students of philosophy who are interested in the realistic conception of truth and in issues in metaphysics related to the correspondence theory of truth, and those interested in Russell and the Tractatus.

: This paper explores how consideration of the notions of naturalness and eligibility, which have played an increasingly significant role in contemporary metaphysics, might impact on the study of truth. In particular, it aims to demonstrate how taking such notions seriously may be of benefit to ‘representational’ theories of truth by showing how the naturalness of truth on a representational account provides a response to the ‘Scope Problem’ presented by Lynch (2009).
According to Frege, judgement is the ‘logically primitive activity’. So what is judgement? In his mature work, he characterizes judging as ‘acknowledging the truth’ (‘Anerkennen der Wahrheit’). Frege’s remarks about judging as acknowledging the truth of a thought require further elaboration and development. I will argue that the development that best suits his argumentative purposes takes acknowledging the truth of a thought to be a non-propositional attitude like seeing an object; it is a mental relation between a (...) thinker, a thought, and an object, namely a truth-value.

This major new study of Heidegger is the first to examine in detail the concept of existential truth that Heidegger developed in the 1920s. Daniel Dahlstrom offers a critical focus on the genesis, nature, and viability of Heidegger's radical reconceptualisation. The book has several distinctive and innovative features. First, it is the only study that attempts to understand the logical dimension of Heidegger's thought in its historical context. Second, no other book-length treatment explores the breadth and depth of Heidegger's (...) confrontation with Husserl, his erstwhile mentor. Third, the book demonstrates that Heidegger's deconstruction of Western thinking occurs on three interconnected fronts: truth, being, and time. Dealing with a crucial aspect of the philosophy of one of the great thinkers of the twentieth century, this book will be important to all scholars and students of Heidegger, be they in philosophy, theology, or literary studies.

Functionalists about truth employ Ramsification to produce an implicit definition of the theoretical term _true_, but doing so requires determining that the theory introducing that term is itself true. A variety of putative dissolutions to this problem of epistemic circularity are shown to be unsatisfactory. One solution is offered on functionalists' behalf, though it has the upshot that they must tread on their anti-pluralist commitments.
This volume is designed to set out some of the central issues in the theory of truth. It draws together, for the first time, the debates between philosophers who favor 'robust' or 'substantive' theories of truth, and those other, 'deflationist' or minimalists, who deny that such theories can be given. The editors provide a substantial introduction, in which they look at how the debates relate to further issues, such as the Liar paradox and formal truth theories.
The paper discusses what kind of truth bearer, or truth-ascription, a deflationist should take as primary. I first present number of arguments against a sententialist view. I then present a deflationary theory which takes propositions as primary, and try to show that it deals neatly with a wide range of linguistic data. Next, I consider both the view that there is no primary truth bearer, and the most common account of sentence truth given by deflationists who (...) take propositions as primary, and argue that they both attribute an implausible type of ambiguity to “true”. This can be avoided, however, if truth-ascriptions to sentences are taken as a certain form of pragmatic ellipses. I end by showing how this hypothesis accommodates a number of intuitions involving truth-ascriptions to sentences. (shrink)
Barry Taylor's book mounts a major new argument against one of the fundamental tenets of much contemporary philosophy, the idea that we can make sense of reality as existing objectively, independently of our capacities to come to know it. He concludes that there is no defensible notion of truth which preserves the theses of traditional realism, nor any extant position sufficiently true to the ideals of that doctrine to inherit its title. In presenting his case Taylor engages with many (...) key works of contemporary metaphysics, semantics, and philosophical logic, so his book will be of interest to a broad spectrum of scholars and students.

I aim to clarify the relationship between the success of a theory and the truth of that theory. This has been a central issue in the debates between realists and anti-realists. Realists assume that success is a reliable indicator of truth, but the details about the respects in which success is a reliable indicator or test of truth have been largely left to our intuitions. Lewis (Synthese 129:371–380, 2001) provides a clear proposal of how success and (...) class='Hi'>truth might be connected, comparing a test of success of our theories to medical tests with low rates of false positives and false negatives. But, contrary to what Lewis claims, I argue that it is not enough for the realist to undercut the claim that success is not a reliable indicator of truth. Rather, the realist must show that our current best theories are likely true. Further, I argue that tests in science are unlike medical tests in a number of important ways. (shrink)
Is truth objective or relative? What exists independently of our minds? The essays in this book debate these two questions, which are among the oldest of philosophical issues and have vexed almost every major philosopher, from Plato, to Kant, to Wittgenstein. Fifteen eminent contributors bring fresh perspectives, renewed energy, and original answers to debates of great interest both within philosophy and in the culture at large.
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 (...) class='Hi'>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.

Hilary Putnam deals in this book with some of the most fundamental persistent problems in philosophy: the nature of truth, knowledge and rationality. His aim is to break down the fixed categories of thought which have always appeared to define and constrain the permissible solutions to these problems.
The word "truth" retains, in common use, traces of origins that link it to trust, troth, and truce, connoting ideas of fidelity, loyalty, and authenticity. The word has become, in contemporary philosophy, encased in a web of technicalities, but we know that a true image is a faithful portrait; a true friend a loyal one. In a novel or a poem, too, we have a feel for what is emotionally true, though we are not concerned with the actuality of (...) events and characters depicted. To have emotions is to care about certain things: we can wonder whether those things are really worth caring about. We can wonder whether our passions reflect who we are, and whether they constitute fitting responses to the vicissitudes of life. So there are two aspects to emotional truth: how well an emotion reflects the threats and promises of the world, and how well it reflects our own individual nature. That is the starting point of this book, which looks first at the analogies and disanalogies between strict propositional truth and a looser, "generic" sense of truth. As applied to emotions, generic truth is closer to those original meanings: as in a portrait's fidelity or friend's loyalty. Taken in this sense, the notion of emotional truth opens up large vistas on areas of life essential to our existence as social beings, and to our concerns with beauty, morality, love, death, sex, knowledge, desire, coherence, and happiness. Each of those topics illustrates some facet of the dominant theme of the book: the crucial but often ambivalent role of our emotions in grounding and yet also sometimes undermining our values. Emotions act, in holistic perspective, as ultimate arbiters of values where different and independently justified standards of value compete. (shrink)
In "Truth and Meaning", Davidson suggested that a truth theory can do the work of a theory of meaning: it can give the meanings of expressions of a language, and can explain the semantic competence of speakers of the language by stating information knowledge of which would suffice for competence. From the start, this program faced certain fundamental objections. One response to these objections has been to supplement the truth theory with additional rules of inference (e.g. from (...) T-sentences to meaning theorems). I argue that these modifications of Davidson's original idea fail to solve the problems with Davidsonian semantics, and that the prospects for a solution to these problems within the Davidsonian framework are dim. A general lesson to be drawn is that Davidsonian theories do not provide a viable alternative to Russellian and Fregean approaches to semantics which recognize the reality of language-independent contents.

The superassertability theory of truth, inspired by Crispin Wright (1992, 2003), holds that a statement is true if and only if it is superassertable in the following sense: it possesses warrant that cannot be defeated by any improvement of our information. While initially promising, the superassertability theory of truth is vulnerable to a persistent difficulty highlighted by James Van Cleve (1996) and Terrence Horgan (1995) but not properly fleshed out: it is formally illegitimate in a similar sense that (...) unsophisticated epistemic theories of truth are widely acknowledged to be. Sustained analysis reveals that the unrestricted formal legitimacy argument is firmly grounded in first person conceivability evidence. (shrink)
