The article delineates the program of a praxeology of truth that allows for studying the dynamics and variability of truth in the sense of situated _doing truth_. It proposes a heuristic differentiation between »truth scenes« and »truth figures« that helps to analyze the emergence of theories of truth as well as that of specific truth cultures.

This book presents a concise introduction to the epistemology and methodology of the Austrian School of economics as defended by Ludwig von Mises. The author provides an innovative interpretation of Mises’ arguments in favour of the a priori truth of praxeology, the received view of which contributed to the academic marginalisation of the Austrian School. The study puts forward a unique argument that Mises – perhaps unintentionally – defends a form of conventionalism. Chapters in the book include detailed (...) discussions of individualism, historicism, epistemological positions, and essentialism. The author goes on to discuss Mises’ justification of the fundamental axiom and proposes a conventionalist interpretation. By presenting praxeology as a conventionalist research programme, the author aims to reinvigorate the interaction between the Austrian School, mainstream economics, and the philosophy of science. This comprehensive reconstruction is suitable for economists interested in the history and philosophy of their discipline, as well as for philosophers of science. (shrink)

I have two objectives in this paper. The first is to investigate whether, and to what extent, truth is valuable. I do this by first isolating the value question from other normative questions. Second, I import into the debate about the nature of truth some key distinctions hailing from value theory. This will help us to clarify the sense in which truth is valuable. I then argue that there is significant variability in the value of truth (...) in different areas of discourse. I shall call this the axiological variability conjecture. I illustrate and substantiate AVC by contrasting the occurrence of disagreement in two paradigmatically evaluative areas of discourse, viz. matters of taste, on the one hand, and morality, on the other. I claim that there is a reasonable tendency to care much more about settling moral disagreements than taste disagreements and that this difference has to do, at least partly but significantly, with the different value that truth exhibits in these two areas of discourse. I then turn to the second objective of the paper—namely, to discuss how pluralistic accounts of the nature of truth may deal with the value of truth in light of AVC. I will argue that AVC is a problem for all versions of truth pluralism that are committed to the following two theses: that truth is a value concept; and that this characteristic of the concept has to be reflected in the metaphysical nature of any admissible truth properties—i.e., all the various properties that are admissible in the pluralist account are value-conferring properties and thus intrinsically valuable. In so doing, I will focus primarily on Michael Lynch’s functionalist incarnation of truth pluralism. Lynch terms this “Manifestation Alethic Pluralism”. My reason for this is twofold: first and foremost, MAP is a paradigmatic exemplification of a model of truth pluralism that is committed to both and ; second, MAP has, to date, enjoyed the most discussion, and currently provides the most developed account of truth pluralism. However, I argue that MAP lacks the resources to account for AVC. Owing to this, I suggest two ways out for an advocate of MAP, which force various structural changes in her view. (shrink)

Kripke’s work on modal logic has been immensely influential. It hardly needs remarking that this is not his only work. Here we address his pioneering applications of fixpoint constructions to the theory of truth, and related work by others. In his fundamental paper on this he explicitly described a modal version, applying a fixpoint construction world by world within a modal frame. This can certainly be carried out, and doubtless has been somewhere. Others have suggested a variety of other (...) extensions such as using the unit interval as the underlying space of truth values, or using a four valued logic instead of three, or various combinations of these. When many similar formal constructions have been proposed, one naturally asks what is the common core. Is there some setting in which things can be proved once and for all, with the various specific proposals seen as applications of this common core. In fact this is the case, with bilattices providing the desired structure. Much of such a development has already appeared in some form or other. It is the purpose of this article to bring everything together, and also add a few things. We present general results that, more or less, have everything currently in the fixpoint literature as special cases. Fortunately this does not make things more complicated, since the underlying proofs are essentially the same as they have always been. It is just that they are being carried out in generality rather than in specificity. (shrink)

It is often thought that instances of the T-schema such as snow is white is true if and only if snow is white state correspondences between sentences andthe world, and that therefore such sentences play a crucial role in correspondence theories oftruth. I argue that this assumption trivializes the correspondence theory: even a disquotationaltheory of truth would be a correspondence theory on this conception. This discussionallows one to get clearer about what a correspondence theory does claim, and toward the (...) end of thepaper I discuss what a true correspondence theory of truth would involve.

First published in 1943 under title: Pragmatism, a new name for some old ways of thinking, and four essays, from The meaning of truth.

Quine rejects Peirce's theory of truth because, among other things, its notion of a limit of a sequence of theories is defective in that the notion of a limit depends on that of nearer than which is defined for numbers but not for theories. This paper shows that the missing definition of nearer than applied to theories can be supplied from within Quine's own epistemology. The upshot is that either Quine's epistemology must be rejected or Peirce's pragmatic theory of (...) truth is partially vindicated. (shrink)

This paper defends a key aspect of the Peircean conception of truth—the idea that truth is in some sense epistemically-constrained. It does so by exploring parallels between Peirce’s epistemology of inquiry and that of Wittgenstein in On Certainty. The central argument defends a Peircean claim about truth by appeal to a view shared by Peirce and Wittgenstein about the structure of reasons. This view relies on the idea that certain claims have a special epistemic status, or function (...) as what are popularly called ‘hinge propositions’. (shrink)

Questions concerning the proof-theoretic strength of classical versus nonclassical theories of truth have received some attention recently. A particularly convenient case study concerns classical and nonclassical axiomatizations of fixed-point semantics. It is known that nonclassical axiomatizations in four- or three-valued logics are substantially weaker than their classical counterparts. In this paper we consider the addition of a suitable conditional to First-Degree Entailment—a logic recently studied by Hannes Leitgeb under the label HYPE. We show in particular that, by formulating the (...) theory PKF over HYPE, one obtains a theory that is sound with respect to fixed-point models, while being proof-theoretically on a par with its classical counterpart KF. Moreover, we establish that also its schematic extension—in the sense of Feferman—is as strong as the schematic extension of KF, thus matching the strength of predicative analysis. (shrink)

"This accessibly written book surveys all of the major competing theories of truth before formulating the new defence of the correspondence theory and then exploring the consequences of the theory for issues in epistemology and ontology. The book concludes by showing how the idea of 'propositional depth' can be used to dissolve the Liar paradoxes."--BOOK JACKET.

With common sense and traditional correspondence theory of truth than the first articulated by James's pragmatism truth has many different characteristics, as well as reflected in these characteristics of the different philosophical connotations. These features and content are how is it? In the historical process of epistemological development without its roots? In this paper, to be adopted by Hume's empiricism contact, especially his causal theory, to trace the epistemological roots of pragmatism truth. Compared by the common and (...) traditional correspondence theory of truth, the pragmatism theory of truth, which is clearly expounded the first time by William James, has many different features and different disposition of philosophy exhibited in such features. This paper intends to explore the basis of Epistemology for such a theory, in reference to another great philosopher-David Hume, especially his theory of causality. (shrink)

Changes in society lead to changes in science, changing its fundamental foundations - ideological and value, methodological and instrumental foundations. In turn, a change in the scientific paradigm leads to social change. A situation of this kind is especially evident in the socio-political sciences, since it is they who are more affected by social reality. The nature of postmodern societies is such that its economic component generates a huge number of subcultures, in the scientific world it is called "subcultural explosion." (...) Postmodern societies are societies of permanent changes: consumer standards, moral values, political structure, and so on, repeatedly change during the life of one generation, significantly affect the search for the truth of science and its understanding. In the list of various questions of truth, its character, origin, postmodern departs from objective truth, therefore it becomes contextual and consensus. Theories are replaced by approaches, views, points of view, thoughts. Scientific concepts with their strict certainty change concepts, in which under the same name everyone puts their own meaning and essence. According to this, in postmodernism, not only the scientific paradigm as a model of scientific activity is changing, but the purpose of science, its understanding as a special activity with the search for truth, is changing. This implies a review of the attitude to the "organizational forms" of science, that is, the way in which scientific knowledge is disseminated to the professional scientific community to search for truth, which in its classical understanding no longer exists.

We investigate how to assign probabilities to sentences that contain a type-free truth predicate. These probability values track how often a sentence is satisfied in transfinite revision sequences, following Gupta and Belnap’s revision theory of truth. This answers an open problem by Leitgeb which asks how one might describe transfinite stages of the revision sequence using such probability functions. We offer a general construction, and explore additional constraints that lead to desirable properties of the resulting probability function. One (...) such property is Leitgeb’s Probabilistic Convention T, which says that the probability of φ equals the probability that φ is true. (shrink)

Contra Lewis, it is argued that the correspondence theory is a genuine rival theory of truth: it goes beyond the redundancy theory; it competes with other theories of truth; it is aptly summarized by the slogan 'truth is correspondence to fact'; and it really is a theory of truth.

Kremer presented three approaches of comparing fixed-point and revision theories of truth in Kremer, 363–403, 2009). Using these approaches, he established the relationships among ten fixed-point theories suggested by Kripke in, 690–716, 1975) and three revision theories presented by Gupta and Belnap in. This paper continues Kremer’s work. We add five other revision theories to the comparisons, including the theory proposed by Gupta in, 1–60, 1982), the theory proposed by Herzberger in, 61–102, 1982), the theory based on fully-varied revision (...) sequences proposed by Gupta and Belnap in, the theory proposed by Yaqūb in, and the theory based on weakly consistent revision sequences. We show that, the notion of Thomason model defined by Belnap’s limit rule is not equivalent to the one defined by Gupta’s limit rule, and that the theory based on fully-varied revision sequences is ≤2-equivalent to the one based on the greatest intrinsic fixed point of σ.

The function of philosophy may be circumscribed as consisting in ma king a keen analysis of the peculiar nature of the crisis-situation, as it has existed among mell throughout th~ centuries of human history, and as it manifested itself in definite ways at the various stages of this his tory. That is to say, philosophy may be regarded as the discipline which, again and again, will have to determine the authenticity of man's ex istence in the light of the changing (...) conditions of life, i. e., man's chang ing needs and interests. Fundamentally, these needs may be regarded as being of a material, an intellectual, an aesthetical and a spiritual kind. On the grounds of the crisis, which inevitably exists among men on ac count of the controversial nature of their various truth-perspectives, as they are postulated on a personal level, in the sciences, in history, in the fine arts and in theology, man creates and re-creates the goods of civilization and the cultural values. The task of philosophy consists then in making an ever new assessment of man's changing needs, in terests and aspirations on the basis of the specific conflicts and prob lems with which man wrestles at a certain historical stage. It is in this way that the important philosophical systems were constructed, which we still admire to-day. (shrink)

The semantic theory of truth, formulated by Alfred Tarski in the 1939s, is primarily a mathematical theory. On the other hand, it also has a considerable philosophical content. This paper presents the second aspect of this theory. It can be shown that several traditional philosophical issues pertaining to the concept of truth can be illuminated by Tarski’s account of truth. It concerns, for instance, the idea of correspondence, the relation of truth and logic, the problem of (...) the relativity/absoluteness of truth, etc. (shrink)

This special issue focuses on two related topics in Ernst Cassirer’s thought: objectivity and truth. Through this lens, the guest editors attempt to illuminate (a) the historical and systematic value of Cassirer’s philosophical project, (b) the continuing relevance of his account of the plurality and universality of human understanding in view of the crisis of truth that currently permeates Western culture, and (c) the way Cassirer’s style can inspire contemporary scholars who wish to evade the analytic-continental divide. Tobias (...) Endres and Simon Truwant gathered twelve contributions from more analytic oriented authors from the philosophy of science and more continental oriented authors from the philosophy of culture. By bringing these scholars together on a shared topic, they hope to help bridging this divide that is also reflected within Cassirer scholarship by preoccupation with either his philosophy of science or philosophy of culture. The articles in this special issue are preceded by a ceremonial speech that Cassirer gave on the occasion of his assumption of the rectorate of the University of Hamburg on November 7, 1929 and that was translated into English for the first time by the guest editors.

Pretheoretically, truth is a correspondence between a sentence and facts. Other so-called theories of truth have typically been resorted to because such a correspondence is thought of as being inexpressible or as being incapable of yielding a definition of truth which expresses what we actually mean. It can be shown that truth is indefinable in the paradigm case of ordinary first-order languages only because they cannot express informational independence. As soon as this is corrected, as in (...) independence-friendly first-order logic, truth predicates are readily definable, Tarski notwithstanding. Hence, there is no reason to think that truth cannot also be defined for our actual working language—Tarski’s “colloquial language.”. (shrink)

As is mentioned in Leigh :845-865, 2015), it is an open problem whether for several axiomatic theories of truth, including Friedman–Sheard theory \ and Kripke–Feferman theory \ :690-716, 1976), there exist cut-elimination arguments that give the upper bounds of their proof-theoretic strengths. In this paper, we give complete cut-elimination results for several well-known axiomatic theories of truth. In particular, we treat the systems \, and \ \\) of Friedman and Sheard’s theories and \.

It is argued here that the existence of various explanatory principles, couched in terms of truth, does not call for an analysis of truth—a theory of its underlying nature. In particular, minimalist accounts are given of three such principles: that true beliefs tend to facilitate the achievement of practical goals; that beliefs obtained as a result of certain methods of inquiry tend to be true; and that the truth of a scientific theory accounts for its empirical success.

In this article, we reassess two of Mises’ core methodological claims. The first claim is that action is necessarily rational. The second claim is that all human minds share a logical structure. Neither claim can be unreservedly accepted but, we argue, both contain truth: Mises’ reflections remain important contributions to our understanding of action and the mind, hence to economics.

In 4.062 of the Tractatus, Wittgenstein repudiates the possibility of “mak[ing] ourselves understood with false propositions just as we have done up until now with true ones”. This chapter challenges this claim by distinguishing two possible cases in which people communicate truth-apt information through false propositions. The first case presents a semantic option, where false propositions become true “construed in the new way” while people aim at conveying truths, whereas the second case presents a pragmatic option, where false propositions (...) remain false while people aim at falsehoods. Wittgenstein’s conclusion applies to the semantic, but not to the pragmatic option. The possibility of falsity-directed communication enables us to reconstruct Dummett’s argument from his analogy between truth and winning, which refutes alethic deflationism. Finally, the chapter reconciles the debate. (shrink)

Slavoj Žižek writes: "Today philosophy is approaching a double end. Physics and brain sciences offer answers to the big metaphysical questions (is the universe infinite? Do we have a free will?), while what remained of philosophy is mostly getting lost in historicist relativism, reducing truth to a discursive “truth-effect.” But more and more people are tired of this game: the need for a new beginning, for authentic metaphysics, is felt everywhere. And Allinson does something that we all secretly (...) knew it has to be done, but nobody dared to actually do it so directly: he convincingly argues for the return to a philosophy that shamelessly addresses big questions. A great sigh of relief will be felt by the readers of Awakening Philosophy: The Loss of Truth: we are back home. If there is justice in our intellectual life, the book will become daily bread for thinking beings." -/- Brian Klug, Emeritus Professor of Philosophy, the University of Oxford writes: "Awakening Philosophy is as original as it is ambitious. Allinson holds up a mirror to academic philosophy and shows how it has become fragmented into an eclectic set of specialisms. He seeks to get philosophy to question itself, thus reviving the spirit of Socratic enquiry: self-examination. In the process, he sets out to recover “the Great Questions” that have exercised philosophers from Plato to such figures as Descartes, Spinoza, Hume, Kant and Husserl. A timely and ground-breaking book." -/- Michael Slote, UST Professor of Ethics, Department of Philosophy, University of Miami, Member, Royal Irish Academy, former Tanner Lecturer, Stanford University, writes: "An elegant and timely appeal for philosophers and the educated public to make use of philosophy's historic roots for purposes of present-day enlightenment." In this original book, Robert Elliott Allinson asserts that philosophers have been lulled into a dogmatic sleep by Immanuel Kant, the slayer of metaphysics, who has convinced them (and the rest of humanity) that we can never know Reality. Allinson awakens global philosophers from their sceptical slumbers by diagnosing the reason why they have abdicated their traditional calling as leaders of inquiry into truth and wisdom. (shrink)
