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.

Most recent discussions of truth ignore the fact that a few philosophers, past and present, have flirted with and sometimes openly subscribed to an identity theory, according to which a proposition's being true consists in its identity with the reality it is supposedly about. This neglect is probably due to the theory's counter-intuitiveness: it faces obvious and fundamental objections. The aim of this paper is to consider these objections and decide if there is a version of the theory which can (...) escape them, thereby becoming an at least initially plausible candidate for an account of truth. In this way the metaphysical price exacted by commitment to an identity theory can be assessed. (shrink)

The coherence of the whole truth is a presupposition of any holistic coherence theory of justification that postulates a positive connection between justification and truth, for unless the whole truth is itself systemically coherent there is no reason to look for systemic coherence when deciding whether one is justified in accepting a given body of beliefs as true. This paper develops a formal model of holistic evidential coherence and uses this model to formalize and defend the claim that the whole (...) truth must be coherent in an evidential sense. (shrink)

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..

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)

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

It is argued that the preservation of truth by an inference relation is of little interest when premiss sets are contradictory. The notion of a level of coherence is introduced and the utility of modal logics in the semantic representation of sets of higher coherence levels is noted. It is shown that this representative role cannot be transferred to first order logic via frame theory since the modal formulae expressing coherence level restrictions are not first order definable. Finally, an inference (...) relation, calledyielding, is introduced which is intermediate between the coherence preservingforcing relation introduced elsewhere by the authors and the coherence destroying, inference relation of classical logic.

Truth is one of the most debated topics in philosophy; Wolfgang Kunne presents a comprehensive critical examination of all major theories, from Aristotle to the present day. He argues that it is possible to give a satisfactory 'modest' account of truth without invoking problematic notions like correspondence, fact, or meaning. The clarity of exposition and the wealth of examples will make Conceptions of Truth an invaluable and stimulating guide for advanced students and scholars.

There is an objection to coherence theories of knowledge to the effect that coherence is not connected with truth, so that when coherence leads to truth this is just a matter of luck. Coherence theories embrace falliblism, to be sure, but that does not sustain the objection. Coherence is connected with truth by principles of justified acceptance that explain the connection between coherence and truth. Coherence is connected with truth by explanatory principle, not just luck.

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

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

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

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

The volume opens with a substantial introduction to theories of truth, aimed at readers with little or no prior knowledge of philosophy.

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

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.
