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)

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)

This paper presents a conception of the self partially in terms of a particular notion of preference. It develops a coherentist account of when one's preferences are "authorized", or sanctioned as one's own, and presents a coherence theory of autonomous action. The view presented solves certain problems with hierarchical accounts of freedom, such as Harry Frankfurt's.

Werkmeister's new book, The Basis and Structure of Knowledge is the second major attempt in recent years to defend the idealistic theory of knowledge. The first was Blanshard's Nature of Thought; and it is worth noticing that both authors, in undertaking the defense of a position long in the shadows, are well aware of contemporary developments in logic and technical philosophy. Werkmeister freely acknowledges his debt to Blanshard; yet his work differs in scope from the latter's in at least (...) two ways. Firstly, the more recent book is concerned largely with the epistemological analysis of meaning and truth and hardly at all with what an older generation called "philosophical psychology," while philosophical psychology fills all of the first and part of the second volume of Blanshard's work. In my opinion, this is all to the good. (That our generation inverts the error and too often indulges in psychological philosophy is another story!) Secondly, Werkmeister presents us with detailed analyses of scientific method, of the structure of scientific theories, and of mathematics, all three areas to which Blanshard pays virtually no attention. The First Part of Werkmeister's book treats of Language and Meaning; the Second of Truth and the World About Us, the Third of Formal Knowledge, and the Fourth Part deals with Empirical Knowledge. But there is a fundamental thesis that runs through all of this. The analysis of each of these four domains reveals, according to Werkmeister, that only a coherence theory of meaning and truth can adequately reflect the criteria actually used by science and commonsense. It is not my intention to rehearse here the familiar dialectic of the arguments for and against this doctrine; the less so, since Werkmeister himself gives a useful review of both sides of the controversy. Rather, I want to try to fix as precisely as possible, within the context of Werkmeister's discussion, the nature of the difference between coherence theories on the one hand and correspondence theories on the other. This difference has not always been too clearly stated; it even seems that recent developments in linguistic analysis have been the occasion for some new confusions on this very point. For coherence theorists who have recognized that philosophical semantics is a "formal" discipline now insist that "to say what a symbol means is not to relate it to an object, but to give it an interpretation in terms of other symbols," as Ayer2 has recently put it. This seems to contradict the "comparison with fact" feature of the traditional realistic formulations of the correspondence view. A superficial bystander could even believe that the correspondence theorists have given up their original position, since both sides now agree that truth is a matter of a relation between symbols. Such agreement, as I hope to show, is more apparent than real, for what is now at stake is the nature of that "intrasymbolic relation." And on this nature the two parties disagree. There is little doubt that Werkmeister's book appears at a moment more propitious for the advocacy of the coherence theory of truth than did Blanshard's. In the near decade that separates the two works the intellectual climate has become, for better or for worse, considerably more favorable to a reconsideration of, and possibly even a reconciliation with, some of the major tenets of rationalism. This is reflected in the current discussion regarding the contrary-to-fact conditional, the dissatisfaction with material implication, and the correlative concern for a more adequate analysis of the concept of a natural law. It is evident too in the revived enthusiasm for intensional logic and in the related interest in the modalities. As uncompromising an empiricist as C. L. Lewis, with whom, by the way, Werkmeister shares a common Kantian background, has introduced into his latest work a "congruence" theory of truth which, despite the substitution of a so-called "probability" inference for necessary inference, looks very much like the coherance criterion all over again. So Werkmeister's book should be welcome for its clear presentation of the relevant issues; and even those who disagree with him can admire the candor and forthrightness with which he champions what remains, despite vacillations, an essentially unpopular position.

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)

As an approach to a Theory of Everything a framework for developing a coherent theory of mathematics and physics together is described. The main characteristic of such a theory is discussed: the theory must be valid and and sufficiently strong, and it must maximally describe its own validity and sufficient strength. The mathematical logical definition of validity is used, and sufficient strength is seen to be a necessary and useful concept. The requirement of maximal description of (...) its own validity and sufficient strength may be useful to reject candidate coherent theories for which the description is less than maximal. Other aspects of a coherent theory discussed include universal applicability, the relation to the anthropic principle, and possible uniqueness. It is suggested that the basic properties of the physical and mathematical universes are entwined with and emerge with a coherent theory. Support for this includes the indirect reality status of properties of very small or very large far away systems compared to moderate sized nearby systems. Discussion of the necessary physical nature of language includes physical models of language and a proof that the meaning content of expressions of any axiomatizable theory seems to be independent of the algorithmic complexity of the theory. Gödel maps seem to be less useful for a coherent theory than for purely mathematical theories because all symbols and words of any language must have representations as states of physical systems already in the domain of a coherent theory.

Susi offers a novel non-coherence theory of digital human rights to explain the change in meaning and scope of human rights rules, principles, ideas and concepts, and the interrelationships and related actors, when moving from the physical domain into the online domain. The transposition into the digital reality can alter the meaning of well-established offline human rights to a wider or narrower extent, impacting core concepts such as transparency, legal certainty and foreseeability. Susi analyses the 'loss in transposition' (...) of some core features of the rights to privacy and freedom of expression. The non-coherence theory is used to explore key human rights theoretical concepts, such as the network society approach, the capabilities approach, transversality, and self-normativity, and it is also applied to e-state and artificial intelligence, challenging the idea of the sameness of rights.

This book offers a comprehensive approach to moral experience. It respects the many dimensions of our moral life which elude the traditional philosophical theories that deal exclusively with principles, consequences, virtues, or some other single dimension. Working from a critique of such traditions, the book shows how to integrate their values in a dynamic coherence. Thus, it is not just another ethical theory, but a new level of philosophizing in ethics which rewards the reader with an enlarged and (...) enriched vision of our complexity as moral beings.

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)

A satisfactory theory of knowledge in which the shortcomings of a pure externalist account are avoided and in which the Gettier problem is solved should consist in a combination of externalist and internalist components. The internalist component should guarantee that the epistemic subject has cognitive access to the justifying grounds of her belief. And the externalist component should guarantee that the justification of her belief does not depend on any false statement. Keith Lehrer's coherence theory of knowledge (...) as undefeated justification is an example of such an internalist-externalist analysis of knowledge. But nevertheless, Lehrer's account leads to unintended results. Therefore, it is argued that a satisfactory coherence theory of knowledge must also be based on a gradual notion of systematic coherence. (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.

The problem of how mathematics and physics are related at a foundational level is of interest. The approach taken here is to work towards a coherent theory of physics and mathematics together by examining the theory experiment connection. The role of an implied theory hierarchy and use of computers in comparing theory and experiment is described. The main idea of the paper is to tighten the theory experiment connection by bringing physical theories, as mathematical structures (...) over C, the complex numbers, closer to what is actually done in experimental measurements and computations. The method replaces C by C n which is the set of pairs, R n,I n, of n figure rational numbers in some basis. The properties of these numbers are based on those of numerical measurement outcomes for continuous variables. A model of space and time based on R n is discussed. The model is scale invariant with regions of constant step size interrupted by exponential jumps. A method of taking the limit n→∞ to obtain locally flat continuum-based space and time is outlined. Also R n based space is invariant under scale transformations. These correspond to expansion and contraction of space relative to a flat background. The location of the origin, which is a space and time singularity, does not change under these transformations. Some properties of quantum mechanics, based on C n and on R n space are briefly investigated. (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..

In their introduction to this volume, Ram and Leake usefully distinguish between task goals and learning goals. Task goals are desired results or states in an external world, while learning goals are desired mental states that a learner seeks to acquire as part of the accomplishment of task goals. We agree with the fundamental claim that learning is an active and strategic process that takes place in the context of tasks and goals (see also Holland, Holyoak, Nisbett, and Thagard, 1986). (...) But there are important questions about the nature of goals that have rarely been addressed. First, how can a cognitive system deal with incompatible task goals? Someone may want both to get lots of research done and to relax and have fun with his or her friends. Learning how to accomplish both these tasks will take place in the context of goals that cannot be fully realized together. Second, how are goals chosen in the first place and why are some goals judged to be more important than others? People do not simply come equipped with goals and priorities: we sometimes have to learn what is important to us by adjusting the importance of goals in the context of other compatible and incompatible goals. This paper presents a theory and a computational model of how goals can be adopted or rejected in the context of decision making. In contrast to classical decision theory, it views decision making as a process not only of choosing actions but also of evaluating goals. Our theory can therefore be construed as concerned with the goal-directed learning of goals. (shrink)
