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)

Arguments pro and contra convergent realism - underdetermination of theory by observational evidence and pessimistic meta-induction from past falsity- are considered. It is argued that, to meet the counter-arguments challenge, convergent realism should be considerably changed with a help of modification of the propositions from this meta-programme’s “hard core” and “protecting belt”. Maybe one of the ways out is to turn to the coherent theory of truth. Some of the works of Hegel (as interpreted by Merab Mamardashvili (...) and Alexandre Kojev), Husserl and Heidegger can help to dig still deeper into the background of this theory. Key words: Husserl, Heidegger, Hegel, convergent realism, internal realism, coherent theory of truth. -/- . (shrink)

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. (shrink)

Recent critics of the coherence theory of truth (notably Ralph Walker) have alleged that the theory is incoherent, since its defence presupposes the correctness of the contrary correspondence theory of truth. Coherentists must specify the system of propositions with which true propositons cohere (the specified system). Generally, coherentists claim that the specified system is a system composed of propositions believed by a community. Critics of coherentism maintain that the coherentist’s assertions about which system is (...) the specified system must be true, not because they cohere with a system of beliefs, but because of facts about what a community believes. I argue that coherentists can admit that there are facts about what systems of beliefs communities accept, without being committed to the claim that these facts are the truth conditions of sentences about what communities accept.

This work attempts to develop a workable formal theory of coherence that avoids the objections traditionally advanced against the earliest versions of the theory. Basically it construes the coherence theory as a criterial rather than definitional approach to truth, i.e., as furnishing a criterion rather than a definition of truth. The problem of criterion is seen as a problem not of guaranteeing but of authorizing criterion. Coherence is a criterion applying to a (...) set of propositions that satisfies the conditions of consistency and connectiveness of the systemic sort. A detailed logical machinery is developed. The pivotal concept is the notion of data as a truth-candidate, "a proposition to be taken not as true, but as potentially or presumptively true.". (shrink)

It is easy to fall for a conceptual beauty and simplicity of the coherence theory of truth. But the texts in which its foundations were for the first time explicitly developed are rich in subtleties, defying a consistent interpretation and inviting various forms of criticism. That is why the following study will take one more look at the writings of Harold H. Joachim and Brand Blanshard, in order to prove that in the analyses which they proposed there (...) is an additional, so far unrecognised element – namely the process of translation – which plays a crucial role in making their accounts valid and complete. Initially then, the article will specify how the notion of translation should be here understood. Next, key postulates of both theories will be recalled, with an indication of several potential inconsistencies which they might entail. Finally, the analysis exposes translative ground of each reconstructed model. What will be thereby underscored, is not only the interpretative depth of Joachim’s and Blanshard’s legacy, but also significance of translation for the philosophical enquiry into the nature of truth.

Although its use is not universal, there is a map of the logical space of theories of truth that is widely applied. According to this map, the most foundational divide amongst theories of truth is that between deflationary and inflationary theories, where, roughly, the former hold that truth is an insubstantial, logical property of little philosophical interest and the latter that it is a substantial property suitable for philosophical attention. Amongst the inflationary theories, there are other fundamental (...) divisions. For example, on the one hand, correspondence theorists hold that the truth of a proposition is a matter of the proposition’s standing in a relation to something else which is not a proposition, such as a fact. On the other hand, coherence theorists hold that the truth of a proposition is a matter of its relations to other propositions. And again, pragmatists hold that the truth of a proposition is a matter of its being useful to believe. Throughout the twentieth century, philosophers used one or other version of this map to orient themselves and their students in the often complex and confusing debates about truth, even while acknowledging that the map may be incomplete in crucial respects (it does not include functionalist and pluralist views, for example). Our objection to the map is not that it is incomplete—although it obviously is—, but that it needs to be radically redrawn. In particular, the familiar division between coherence theories and correspondence theories needs to be rethought. The coherence theory is so often glibly dismissed as absurd that labelling someone as a coherence theorist is often seen as reason enough to ignore them.1 While none of the philosophers usually so labelled should be ignored, we shall argue (§3) that none of them actually held this view anyway. The difficulty—perhaps impossibility—of finding a genuine coherence theorist of truth strikes us as more than just an indication that this is a rare animal. Rather, it suggests the possibility of something significant, namely, that the only occupant of this position in historical space is a set of slogans; this would give us some reason to suppose that the logical space of theories is just as empty at this point..

1. Introduction. In recent years Brand Blanshard’s formulation of the coherence theory of truth, as he articulated it in The Nature of Thought, has come under formidable attack by Professor Nicholas Rescher of the University of Pittsburgh. In his otherwise excellent book, The Coherence Theory of Truth, later excerpted for P. A. Schilpp’s Library of Living Philosophers volume on Professor Blanshard, he criticizes Blanshard on two main counts.

A massive series of meticulous clarifications and arguments is marshalled to attempt to refute, first, the doctrine that all relations are "internal", next, the claims that coherence is the sole criterion of the nature of truth, and finally, the theory of degrees of truth and falsity. The author's great familiarity with the literature of the coherence theorists proves almost a drawback: he prefers to cite texts extensively, but must then acknowledge important differences among them. There (...) is little in the way of a constructive alternative theory of truth, but the criticism is formidable.--W. L. M. (shrink)

In this paper I examine five essential themes in Brand Blanshard's coherence theory of truth. Blanshard defines truth in terms of the rational or the interdependence of concepts, where concepts determine objects of experience rather than merely conform to them. On this view, truth is contextual and is the approximation of thought to reality or the systemization of the two ends - the immanent and transcendent. I raise some worries for this account of truth, (...) foremost of which is the worry that it commits us to a deep-seated skepticism, both theoretical and practical. In order to be able to tell when the immanent end is achieved and if it is making progress towards the transcendent end (i.e., when the ultimate systematization is realized), we require an omniscient standpoint of cosmic order or overarching system of beliefs. While this seems possible in principle it is not so in practice. (shrink)

Against blanshard's classic argument for coherence, i maintain that coherence is neither the sole criterion nor nature of truth. in the face of blanshard's insistence that, since truth cannot be a matter of correspondence it must necessarily be a matter of coherence, i propose and defend a third option which combines the two polar positions. i develop this option through analysis of kant's writings on truth.

I argue that coherentists can admit that there are facts about what systems of beliefs communities accept, without being committed to the claim that these facts are the truth conditions of sentences about what communities accept. (edited).

In the Tractatus, Wittgenstein maintains that “The world is all that is the case.” Some philosophers have seen an advantage in introducing into a formal language either a constant which will represent the world, or an operator, e.g., ‘Max’, such that indicates that p gives a complete description of the actual world, of the world at some instant of time, or of a possible world. Such propositions are called world propositions, possible world propositions, or maximal propositions. For us, a maximal (...) proposition is a possible world proposition; it gives a complete description of one way the world might be. A maximal proposition p is not logically false, and for any proposition q, either p entails q or p entails not-q. (shrink)
