ABSTRACT: Frege, and others who followed him, stressed the role of fallibility as a means to defining ‘objectivity.’ By defining objective judgments as fallible, these philosophers contributed to the consolidation of a theory of objectivity which suggested interpreting epistemological, as well as other judgements, as being objective. An important philosophical implication of this theory lies in its disclosure of the interrelations between truth and objectivity. In light of this insight, and based on an analysis of instances of false (epistemological and (...) other) judgments, I show that truth and objectivity go hand-in-hand, while falsity and objectivity do not. This finding alone indicates the necessity to revise the theory of objectivity. (shrink)

This chapter attempts to give a brief overview of nonclassical (-logic) theories of truth. Due to space limitations, we follow a victory-through-sacrifice policy: sacrifice details in exchange for clarity of big-picture ideas. This policy results in our giving all-too-brief treatment to certain topics that have dominated discussion in the non-classical-logic area of truth studies. (This is particularly so of the ‘suitable conditoinal’ issue: §4.3.) Still, we present enough representative ideas that one may fruitfully turn from this essay to the more-detailed (...) cited works for further study. Throughout – again, due to space – we focus only on the most central motivation for standard non-classical-logic-based truth theories: namely, truth-theoretic paradox (specifically, due to space, the liar paradox).

To attribute confusion to someone is to take up a paternalistic stance in evaluating his reasoning.

This reference work offers a representative and reliable survey of classical, medieval, and modern history in regards to the philosophical term, truth .

This paper proposes a critical analysis of that interpretation of the Nāgārjunian doctrine of the two truths as summarized—by both Mark Siderits and Jay L. Garfield—in the formula: “the ultimate truth is that there is no ultimate truth”. This ‘semantic reading’ of Nāgārjuna’s theory, despite its importance as a criticism of the ‘metaphysical interpretations’, would in itself be defective and improbable. Indeed, firstly, semantic interpretation presents a formal defect: it fails to clearly and explicitly express that which it contains logically; (...) the previously mentioned formula must necessarily be completed by: “the conventional truth is that nothing is conventional truth”. Secondly, after having recognized what Siderits’ and Garfield’s analyses contain implicitly, other logical and philological defects in their position emerge: the existence of the ‘conventional’ would appear—despite the efforts of semantic interpreters to demonstrate quite the contrary—definitively inconceivable without the presupposition of something ‘real’; moreover, the number of verses in Nāgārjuna that are in opposition to the semantic interpretation (even if we grant semantic interpreters that these verses do not justify a metaphysical reconstruction of Nagarjuna’s doctrine) would seem too great and significant to be ignored.

Analytic philosophy has recently demonstrated a revived interest in metaphysical problems about possibility and necessity. Graeme Forbes here provides a careful description of the logical background of recent work in this area for those who may be unfamiliar with it, moving on to d discuss the distinction between modality de re and modality de dicto and the ontological commitments of possible worlds semantics. In addition, Forbes offers a unified theory of the essential properties of sets, organisms, artefacts, substances, and events, (...) based on the doctrine that identity facts must be intrinsically grounded, and analyzes and rejects apparent counterexamples to this doctrine.

The book interconnects many science topics, including cosmology, neurobiology and evolution, to religion and the arts.

Analytic philosophy generally follows Frege in insisting that concepts be defined so as to eliminate vagueness. In practice, however, context often provides the clarit y that definitions fail to supply. Wittgenstein’s later work stressed context (use) rather than definition, at least for philosophical (as opposed to scientific) discourse. In this Wittgenstein’s development was opposite to Frege’s.Richard Robinson notes the looseness in original language learning, and that precision is often nevertheless achieved, especially in sciences. Hence Robinson’s paradox: the inevitability of vagueness (...) at the roots of precision. Analytic explanations contrast with contextual ones. We can sometimes explain meaning analytically, but we must sometimes use contextual explanations. Vagueness cannot be eliminated, and wholesale analysis is a chimerical ideal in philosophy. We need, as Wittgenstein came to see, a broader, more general, conception of cIarity, within which analytic (Iogical) clarity is only one special case. (shrink)

The article is a commentary to Susan Haack’s The Whole Truth and Nothing but the Truth. It consists of two parts. In the first one some doubts about Haack’s conception of partiality of truth are formulated. However, Haack’s concept of truth is treated as one of the assumptions and not brought up for discussion. In the second part of the article a simple typology of possible sources of truth’s partiality in science is presented. The list includes deliberate and unintentional omissions, (...) misleading, lack of scientific interest, unattainability, and epistemological problems with truth and realism. (shrink)

There is one truth, but many truths: i.e., one unambiguous, non-relative truth-concept, but many and various propositions that are true. One truth-concept: to say that a proposition is true is to say (not that anyone, or everyone, believes it, but) that things are as it says; but many truths: particular empirical claims, scientific theories, historical propositions, mathematical theorems, logical principles, textual interpretations, statements about what a person wants or believes or intends, about grammatical and legal rules, etc., etc. But, as (...) Frank Ramsey once said, “There is no platitude so obvious that eminent philosophers have not denied it”; and as soon as you ask why anyone would deny that there is one truth-concept, or that there are many true propositions, it becomes apparent that my initial, simple formula disguises many complexities.

The first systematic exposition of all the central topics in the philosophy of logic, Susan Haack's book has established an international reputation (translated into five languages) for its accessibility, clarity, conciseness, orderliness, and range as well as for its thorough scholarship and careful analyses. Haack discusses the scope and purpose of logic, validity, truth-functions, quantification and ontology, names, descriptions, truth, truth-bearers, the set-theoretical and semantic paradoxes, and modality. She also explores the motivations for a whole range of nonclassical systems of (...) logic, including many-valued logics, fuzzy logic, modal and tense logics, and relevance logics. (shrink)

In recent times the question of whether or not there is such a thing as nonconceptual content has been the object of much serious attention. For analytical philosophers, the locus classicus of the view that there is such a phenomena is to be found in Evans remarks about perceptual experience in Varieties of Reference. John McDowell has taken issue with Evans over his claim that "conceptual capacities are first brought into operation only when one makes a judgement of experience, and (...) at that point a different species of content comes into play" (McDowell 1994: 48). In contrast, he proposes that "A judgement of experience does not introduce a new kind of content, but simply endorses the conceptual content, or some of it, that is already possessed by the experience on which it is grounded" (McDowell 1994: 48-49). Ironically, in light of the ambitions of Mind and World, this sits very happily with the firmly embedded views of many traditional classical cognitivists. It has been a long-standing article of faith that, even in its most basic forms, perceptual content must be conceptual. But those who adopt this position have a heavy burden when it comes to explaining the origin and development of concepts (cf. Peacocke 1992a: 9). In line with the proposal that at least some primitive concepts must be innate, theorists like Fodor make appeal to the intrinsic character of such concepts to explain more complex conceptual contents and their essential characteristics (Fodor 1998: 130). Primitive concepts and their properties as simply assumed because of an explanatory need despite that fact that making this assumption has a paradoxical consequence --which, in this case, is revealed by Fodor's claim that all concepts must be acquired inductively (cf. Fodor 1998: 130-132). The good news is that if we opt for a nonconceptualist approach then we need not assume that any concepts are innate. There is a plausible programme afoot, initiated by Cussins, which hopes explain "the construction of cognitive properties out of non-cognitive properties" (Cussins 1990: 374). He encourages us to suppose "that the mind/world distinction is a phylogenetic or ontogenetic achievement" (Cussins 1990: 409). However, some advocates of nonconceptual content believe that providing this explanation will be a relatively straightforward, although clearly difficult, task given that a contentful base of nonconceptual informational states, of the kind Evans envisioned, is presupposed. My aim is to defend Evans but if if nonconceptual content is to play the important role assigned to it of helping to explain the development of concepts then we must explicate the nature of such content in such a way that does not presuppose that it is truth-conditional. We must also be able to say exactly what part nonconceptual responses play in judgement making and conceptual development. It is the burden of this paper to provide a sketch of how both these ends might be achieved and to offer some reasons for thinking the project is a viable one. I do this in two stages. The first is to advocate a modest biosemantic theory of nonconceptual content and the second is to show how this can shore up a Davidsonian understanding of the possession conditions for concepts.

Cieslinski has given an interesting response to Shapiro 1998 and Ketland 1999, which argued that deflationary truth theories are inadequate, since they lack the property of ‘reflective adequacy’. Cieslinski’s response, following Tennant (2002, 2005), aims to explain, without a detour using truth axioms, why someone who accepts the axioms of a theory should also accept its reflection principles. The argument is formulated very clearly (in fact, to justify a different reflection principle), and involves a couple of important assumptions, the crucial (...) one being that the reflection scheme for a theory ‘expresses’ the acceptance of its theorems. I argue that this assumption is incorrect. For if the reflection principle for a theory expresses the claim that one is ready to accept its theorems, this latter claim should imply the reflection principle. But it does not. So, I conclude, the response fails to yield the required ‘truth-free’ method for proving or justifying reflection principles. (shrink)

This lucid and comprehensive essay by a distinguished philosopher surveys the views of Plato, Aristotle, Leibniz, and Kant on the nature of mathematics. It examines the propositions and theories of the schools these philosophers inspired, and it concludes by discussing the relationship between mathematical theories, empirical data, and philosophical presuppositions. 1968 edition.

In a wide-ranging inquiry Richard W. Miller provides new resources for coping with the most troubling types of moral conflict: disagreements in moral conviction, conflicting interests, and the tension between conscience and desires. Drawing on most fields in philosophy and the social sciences, including his previous work in the philosophy of science, he presents an account of our access to moral truth, and, within this framework, develops a theory of justice and an assessment of the role of morality in rational (...) choice. In Miller's view, we are often in a position to claim that our moral judgments are true descriptions of moral facts. But others, relying on contrary ways of moral learning, would reject truths that we are in a position to assert, in dissent that does not depend on irrationality or ignorance of relevant evidence or arguments. With this mixed verdict on moral realism, Miller challenges many received views of rationality, scientific method, and the relation between moral belief and moral choice. In his discussion of justice, Miller defends the adequacy, for modern political choices, of a widely shared demand that institutions be freely and rationally acceptable to all. Drawing on social research and economic theories, he argues that this demand has dramatically egalitarian consequences, even though it is a premise of liberals and conservatives alike. In the final chapters, Miller investigates the role and limits of morality in the choice of conduct, arguing for new perspectives on reason and impartiality. (shrink)

Something is called true because it conforms to some measure. Since what measures is logically prior to what it measures, the latter is always secondarily speaking true. Further, what is secondarily speaking true pictures its measure. In all there are six types of such picturing. Since “true” is inherently referential and the latter is the mark of mind, truth is properly speaking mind-dependent. Besides, truth has the same status as falsity, and falsity is mind-dependent. That implies that the measures in (...) truth are mind-dependent. That mind is either human or divine. All mind-independent things are improperly speaking true. They are called true only because they bear some relation to what is strictly speaking true. But not all that is secondarily speaking true is improperly speaking true. Judgments are secondarily speaking true since they are measured by facts but are nonetheless properly speaking true. A nominalist alternative to this assay is traced to Aristotle. It is too narrow to catch all types of truth. A conceptualist analysis implicates its defenders in a dilemma in which what they say is either false or contradictory. (shrink)

The paper attempts to clarify some fundamental aspects of an explanationof the concept of truth which is neither deflationary nor substantive.The main aspect examined in detail concerns the ontological dimension of truth, the mind/language-world connection traditionally associated with the concept of truth. It is claimed that it does not make sense to defend or reject a relatedness of truth to the ontological dimension so long as the kind of presupposed or envisaged ontology is not made explicit and critically examined. In (...) particular, it is shown that generally an objectual ontology is – often only implicitly – presupposed, i.e., an ontology admitting objects (substances), properties, relations, sometimes also facts, events, and the like. The paper demonstrates that such an ontology derives from the Principle of Semantic Sentential Compositionality and that this principle should be rejected. It introduces instead the Principle of Semantic Sentential Contextuality (or Context Principle) as the semantic basis of a new ontology, an ontology of primary states of affairs. After sketching such an ontology, it is shown that the relatedness of truth to the ontological dimension becomes intelligible. (shrink)

My target in this paper is a view that has sometimes been called the ‘Linguistic Doctrine of Necessary Truth’ (L-DONT) and sometimes ‘Conventionalism about Necessity’. It is the view that necessity is grounded in the meanings of our expressions—meanings which are sometimes identified with the conventions governing those expressions—and that our knowledge of that necessity is based on our knowledge of those meanings or conventions. In its simplest form the view states that a truth, if it is necessary, is necessary (...) (and knowably necessary) because it is analytic. It is widely recognized that this simple version of the view faces a prima facie problem with the existence of the necessary a posteriori. Assuming that all analytic truths are a priori, if there are necessary a posteriori truths then there are necessary synthetic truths—contradicting the view’s claim that all necessary truths are analytic. Contemporary L-DONTers have things to say about the problem, but in this paper I want to suggest that there is a different, more serious, problem which arises from the phenomenon of indexicality, which L-DONTers have not taken account of. Though there are many versions of the problem, a simple one is this. Consider Kaplan’s celebrated sentence. (shrink)

In this paper I explore why one might hope to, and how to begin to, develop an expressivist account of truth – that is, a semantics for ‘true’ and ‘false’ within an expressivist framework. I do so for a few reasons: because certain features of deflationism seem to me to require some sort of nondescriptivist semantics, because of all nondescriptivist semantic frameworks which are capable of yielding definite predictions rather than consisting merely of hand-waving, expressivism is that with which I (...) am most familiar, and because I believe that certain problems about truth and particularly about paradox seem to me to look different, when seen through the lens of an expressivist theory. I don’t mean to defend such a theory in this paper, and indeed I have cast doubts on the ultimate prospects of the framework I will be employing here elsewhere.1 But I do think that seeing what an expressivist theory of truth would look like helps to shed light on both expressivism and on truth.

In this paper I respond to Jacquette’s criticisms, in (Jacquette, 2008), of my (Barker, 2008). In so doing, I argue that the Liar paradox is in fact a problem about the disquotational schema, and that nothing in Jacquette’s paper undermines this diagnosis.

This paper argues that, contrary to P. Eldridge-Smith, the so-called Pinocchio paradox affords no argument against ‘simply semantic dialetheism’.

Coherence theories are regularly confronted with the objection that there can be many coherent systems, so that mere coherence is said to be insufficient as either the defining element of truth or even as a working criterion of truth. This objection has been called the “master objection”. If someone is taking coherence not only as a criterion supporting the truth of a theory, but as an ingredient to a definition of “true” she has to attack the master objection straight on.
