In this sequel toSelf-reference in arithmetic Iwe continue our discussion of the question: What does it mean for a sentence of arithmetic to ascribe to itself a property? We investigate how the properties of the supposedly self-referential sentences depend on the chosen coding, the formulae expressing the properties and the way a fixed point for the expressing formulae are obtained. In this second part we look at some further examples. In particular, we study sentences apparently expressing their Rosser-provability, their own${\rm{\Sigma (...) }}_n^0$-truth or their own${\rm{\Pi }}_n^0$-truth. Finally we offer an assessment of the results of both papers. (shrink)

At the centre of the traditional discussion of truth is the question of how truth is defined. Recent research, especially with the development of deflationist accounts of truth, has tended to take truth as an undefined primitive notion governed by axioms, while the liar paradox and cognate paradoxes pose problems for certain seemingly natural axioms for truth. In this book, Volker Halbach examines the most important axiomatizations of truth, explores their properties and shows how the logical results impinge on (...) the philosophical topics related to truth. In particular, he shows that the discussion on topics such as deflationism about truth depends on the solution of the paradoxes. His book is an invaluable survey of the logical background to the philosophical discussion of truth, and will be indispensable reading for any graduate or professional philosopher in theories of truth.

The uniform reflection principle for the theory of uniform T-sentences is added to PA. The resulting system is justified on the basis of a disquotationalist theory of truth where the provability predicate is conceived as a special kind of analyticity. The system is equivalent to the system ACA of arithmetical comprehension. If the truth predicate is also allowed to occur in the sentences that are inserted in the T-sentences, yet not in the scope of negation, the system with the reflection (...) schema for these T-sentences assumes the strength of the Kripke-Feferman theory KF, and thus of ramified analysis up to $\varepsilon_0$.

Wittgenstein’s Whewell’s Court Lectures contains previously unpublished notes from lectures given by Ludwig Wittgenstein between 1938 and 1941. The volume offers new insight into the development of Wittgenstein’s thought and includes some of the finest examples of Wittgenstein’s lectures in regard to both content and reliability.

We investigate axiomatizations of Kripke's theory of truth based on the Strong Kleene evaluation scheme for treating sentences lacking a truth value. Feferman's axiomatization KF formulated in classical logic is an indirect approach, because it is not sound with respect to Kripke's semantics in the straightforward sense: only the sentences that can be proved to be true in KF are valid in Kripke's partial models. Reinhardt proposed to focus just on the sentences that can be proved to be true in (...) KF and conjectured that the detour through classical logic in KF is dispensable. We refute Reinhardt's Conjecture, and provide a direct axiomatization PKF of Kripke's theory in partial logic. We argue that any natural axiomatization of Kripke's theory in Strong Kleene logic has the same proof-theoretic strength as PKF, namely the strength of the system RA< ωω ramified analysis or a system of Tarskian ramified truth up to ωω. Thus any such axiomatization is much weaker than Feferman's axiomatization KF in classical logic, which is equivalent to the system RA<ε₀ of ramified analysis up to ε₀. (shrink)

Epiphenomenalism has been criticized with several objections. It has been argued that epiphenomenalism is incompatible with the alleged causal relevance of mental states, and that it renders knowledge of our own conscious states impossible. In this article, it is demonstrated that qualia-epiphenomenalism follows from some well- founded assumptions, and that it meets the cited objections. Though not free from difficulties, it is at least superior to its main competitors, namely, physicalism and interactionism.

On the one hand, the concept of truth is a major research subject in analytic philosophy. On the other hand, mathematical logicians have developed sophisticated logical theories of truth and the paradoxes. Recent developments in logical theories of the semantical paradoxes are highly relevant for philosophical research on the notion of truth. And conversely, philosophical guidance is necessary for the development of logical theories of truth and the paradoxes. From this perspective, this volume intends to reflect and promote deeper interaction (...) and collaboration between philosophers and logicians investigating the concept of truth than has existed so far.Aside from an extended introductory overview of recent work in the theory of truth, the volume consists of articles by leading philosophers and logicians on subjects and debates that are situated on the interface between logical and philosophical theories of truth. The volume is intended for graduate students in philosophy and in logic who want an introduction to contemporary research in this area, as well as for professional philosophers and logicians.

Based on a critical reading of Jürgen Habermas’s journalistic writings on the European Union, the article argues that Europe’s current crisis is also a crisis of its narratives, and hence a crisis of meaning. The German philosopher has revised his political vision of a united Europe but has done so without abandoning his neo-Kantian ‘soft revolutionism’. The EU of the future is not only envisaged as an alternative to the allegedly defunct European nation-state, but also as the antithesis to US-style (...) federalism and to what is called ‘post-democratic executive federalism’. What is more, Habermas no longer fully trusts in the power of the better argument, as championed in his critical social theory. Instead, his hope of normative progress towards a socially and politically more integrated Europe is founded on a belief in the power of the crisis itself – aided by a convincing pro-European narrative – to drive us in the same direction as that indicated by reason. The conclusion contrasts Habermas’s utopian Europeanism, which has failed to find favour with the wider European public, with a less utopian alternative inspired by the highly specific, non-universal situation of the Old Continent.

International organizations such as the UN, EU and IMF play an increasingly important role in international politics. Fully revised and updated, this broad-ranging text provides a systematic theoretical and empirical introduction to the structure, policies and performance of international organizations.

The purpose of this article is to explore the potential contribution of Axel Honneth's critical theory of recognition to empirical and normative debates on global justice. I first present, very briefly, an overview of recent theories of global distributive justice. I argue that theorists of distributive justice do not pay enough attention to sources of self-respect and conditions for identity formation, and that they are blind toward the danger of harming people's sense of self even by well-intentioned redistributive policies. Honneth's (...) theory suffers from complementary shortcomings; it is anti-technocratic but largely oblivious to the global nature of many contemporary justice claims. Given this situation, I seek to broaden the theory's scope by outlining transnational extensions of the recognition principles of love, rights and solidarity identified by Honneth. In conclusion, I show how utilizing a broadened conceptualization of the struggle for recognition allows us to better understand the changing logic of justice-oriented foreign policies. (shrink)

Solutions to semantic paradoxes often involve restrictions of classical logic for semantic vocabulary. In the paper we investigate the costs of these restrictions in a model case. In particular, we fix two systems of truth capturing the same conception of truth: of the system KF of Feferman formulated in classical logic, and the system PKF of Halbach and Horsten, formulated in basic De Morgan logic. The classical system is known to be much stronger than the nonclassical one. We assess the (...) reasons for this asymmetry by showing that the truth theoretic principles of PKF cannot be blamed: PKF with induction restricted to non-semantic vocabulary coincides in fact with what the restricted version of KF proves true.

The attempts to mitigate the unprecedented health, economic, and social disruptions caused by the COVID-19 pandemic are largely dependent on establishing compliance to behavioral guidelines and rules that reduce the risk of infection. Here, by conducting an online survey that tested participants’ knowledge about the disease and measured demographic, attitudinal, and cognitive variables, we identify predictors of self-reported social distancing and hygiene behavior. To investigate the cognitive processes underlying health-prevention behavior in the pandemic, we co-opted the dual-process model of thinking (...) to measure participants’ propensities for automatic and intuitive thinking vs. controlled and reflective thinking. Self-reports of 17 precautionary behaviors, including regular hand washing, social distancing, and wearing a face mask, served as a dependent measure. The results of hierarchical regressions showed that age, risk-taking propensity, and concern about the pandemic predicted adoption of precautionary behavior. Variance in cognitive processes also predicted precautionary behavior: participants with higher scores for controlled thinking (measured with the Cognitive Reflection Test) reported less adherence to specific guidelines, as did respondents with a poor understanding of the infection and transmission mechanism of the COVID-19 virus. The predictive power of this model was comparable to an approach (Theory of Planned Behavior) based on attitudes to health behavior. Given these results, we propose the inclusion of measures of cognitive reflection and mental model variables in predictive models of compliance, and future studies of precautionary behavior to establish how cognitive variables are linked with people’s information processing and social norms.

This contribution attempts to define the relation between phenomenology and philosophy of practice by considering their respective conceptions of philosophy and especially the consequences of modern critiques of metaphysics. The two characteristic perspectives of performative metaphysics and of meaning analysis are used for further critical inquiry into the standpoints of phenomenology and philosophy of practice. As a conclusion, this inquiry is continued in a common area of interest of both standpoints, that is, the relation between personality and embodied being.

To the axioms of Peano arithmetic formulated in a language with an additional unary predicate symbol T we add the rules of necessitation and conecessitation T and axioms stating that T commutes with the logical connectives and quantifiers. By a result of McGee this theory is -inconsistent, but it can be approximated by models obtained by a kind of rule-of-revision semantics. Furthermore we prove that FS is equivalent to a system already studied by Friedman and Sheard and give an analysis (...) of its proof theory. (shrink)

According to the disquotationalist theory of truth, the Tarskian equivalences, conceived as axioms, yield all there is to say about truth. Several authors have claimed that the expression of infinite conjunctions and disjunctions is the only purpose of the disquotationalist truth predicate. The way in which infinite conjunctions can be expressed by an axiomatized truth predicate is explored and it is considered whether the disquotationalist truth predicate is adequate for this purpose.

Disquotational theories of truth, that is, theories of truth based on the T-sentences or similar equivalences as axioms are often thought to be deductively weak. This view is correct if the truth predicate is allowed to apply only to sentences not containing the truth predicate. By taking a slightly more liberal approach toward the paradoxes, I obtain a disquotational theory of truth that is proof theoretically as strong as compositional theories such as the Kripket probe the compositional axioms.

To the axioms of Peano arithmetic formulated in a language with an additional unary predicate symbol T we add the rules of necessitation φ/Tφ and conecessitation T φ/φ and axioms stating that T commutes with the logical connectives and quantifiers. By a result of McGee this theory is w-inconsistent, but it can be approximated by models obtained by a kind of rule-of-revision semantics. Furthermore we prove that FS is equivalent to a system already studied by Friedman and Sheard and give (...) an analysis of its proof theory. (shrink)

If □ is conceived as an operator, i.e., an expression that gives applied to a formula another formula, the expressive power of the language is severely restricted when compared to a language where □ is conceived as a predicate, i.e., an expression that yields a formula if it is applied to a term. This consideration favours the predicate approach. The predicate view, however, is threatened mainly by two problems: Some obvious predicate systems are inconsistent, and possible-worlds semantics for predicates of (...) sentences has not been developed very far. By introducing possible-worlds semantics for the language of arithmetic plus the unary predicate □, we tackle both problems. Given a frame (W, R) consisting of a set W of worlds and a binary relation R on W, we investigate whether we can interpret □ at every world in such a way that □ $\ulcorner A \ulcorner$ holds at a world ᵆ ∊ W if and only if A holds at every world $\upsilon$ ∊ W such that ᵆR $\upsilon$ . The arithmetical vocabulary is interpreted by the standard model at every world. Several 'paradoxes' (like Montague's Theorem, Gödel's Second Incompleteness Theorem, McGee's Theorem on the ω-inconsistency of certain truth theories, etc.) show that many frames, e.g., reflexive frames, do not allow for such an interpretation. We present sufficient and necessary conditions for the existence of a suitable interpretation of □ at any world. Sound and complete semi-formal systems, corresponding to the modal systems K and K4, for the class of all possible-worlds models for predicates and all transitive possible-worlds models are presented. We apply our account also to nonstandard models of arithmetic and other languages than the language of arithmetic. (shrink)

Over the past decades, we have witnessed calls for greater transdisciplinary engagement between scientific and societal actors to develop more robust answers to complex societal challenges. Although there seems to be agreement that these approaches might nurture innovations of a new kind, we know little regarding the research practices, their potential, and the limitations. To fill this gap, this article investigates a funding scheme in the area of transdisciplinary sustainability research. It offers a detailed analysis of the imaginaries and expectations (...) on which the funding scheme rests and how researchers actually practice transdisciplinarity within the respective projects. Identifying three ideal typical models of science–society relations at work, attention is paid to how, where, and when societal and scientific arenas get entangled. This article discusses the tensions between classical academic values and efforts to open research to society, the prevailing power structures that make societal participation challenging, the importance of place and technopolitical cultures, and how temporal project structures impede more radical openings to new ways of knowledge production. We finally emphasize that transdisciplinary knowledge production can only become a serious option for addressing societal challenges if broader changes are made to the knowledge regimes in place.

The acceleration and qualitative change of West European integration in the 1980s — as evidenced by the Single European Act — were big events of the world political economy of that decade. They not only paved the way for political union, but also altered the competition in the Triad — United States, Western Europe and Japan. This article analyzes the relaunch of the European Community and later European Union in the framework of conflictive evolutionary theory. Two elements of that theory (...) are combined to explain the timing, the forces behind and the actors involved. The arguments are developed from the theory of the rise and decline of societal models and from the theory of competition among governments in the world market for social order and protection. The thesis of an elite argain among European transnational corporations and the EC-Commission is exposed ana briefly confronted with empirical evidence from the author's research. The article also reflects the competitive position of Western Europe in the Triad and draws conclusions for the future structure of the core: no hegemon similar to Britain's and America's position in the past will emerge since the systemic conditions have changed.

Dem Beitrag geht es darum, den modernen olympischen Wettkampfsport als spezifische Form von Körpertechnologisierung zu charakterisieren und zugleich die Relevanz der Thematisierung des Sports für die praktische Philosophie aufzuzeigen. Dazu wird der Sport als alltäglicher und akzeptierter Fall von Körpertechnologisierung im Kontext der allgemeinen philosophischen Diskussion um Formen von Enhancement diskutiert. Die Spezifik olympisch-sportlicher Körpertechnologisierung liegt darin, dass die dort praktizierte Leistungssteigerung eine innere Norm, ein Maß im Hegel’schen Sinne hat. Olympische Leistungssteigerung ist kein maßloses Immer-schneller, Immer-höher, Immer-stärker, sondern eine (...) Steigerung, die unter einer sportspezifischen Bedingung steht. Deshalb kann der olympische Sport kritisiert werden, indem man ihn beim Wort seiner Verfasstheit nimmt. Wenn man ihn loben oder beargwöhnen will, muss man nicht zurückgreifen auf kulturkritisch geprägte Bedenken gegen maßlose Leistungssteigerung oder zynische Gleichgültigkeit gegenüber dem, was Individuen ihren Körpern antun.

) Modern theories of formal truth have traditionally been used to analyse semantic paradoxes, but their field of application goes well beyond this field to include ontological issues, Godel′s incompleteness phenomena, and the relationship between object language, meta language and reduction. All these fields have had new light sched upon them by studies on the theories of truth. In providing a first summary of the various approaches in this field the author documents their respective advantages and areas of application. The (...) emphasis here is on the axiomatic theories of truth developed by Cantini, Feferman, Friedman and the autor himself, which over the past ten years have increasingly gained ground over the semantic theories of Kripke et al. The book describes the way in which many of the aciomatic proposals are built up and expand on semantic theories. This ist the first time that the results in this field have been made accessible to readers in their larger context. The book deals in detail with the technical aspects and so is ideal as a point of entry into the vast array of literature on the metamathematics of this field. A key objective of the book is to extablish a connection between the latest theories of truth and the older constructions elaborated by Tarski. He made a number of important findings about the formal properties of truth back in the 1930s, but some of his constructions are now considered to be obsolete. Tarski′s views appear in a new light in this book since some of his ideas have only been formulated in recent years. (shrink)

This chapter discusses the complex conditions for the emergence of 19th-century symbolic logic. The main scope will be on the mathematical motives leading to the interest in logic; the philosophical context will be dealt with only in passing. The main object of study will be the algebra of logic in its British and German versions. Special emphasis will be laid on the systems of George Boole and above all of his German follower Ernst Schröder.

Some axiomatic theories of truth and related subsystems of second-order arithmetic are surveyed and shown to be conservative over their respective base theory. In particular, it is shown by purely finitistically means that the theory PA ÷ "there is a satisfaction class" and the theory FS of [2] are conservative over PA.

English summary: From an international and interdisciplinary viewpoint, Thomas Aquinas was the most important scholastic philosopher and theologian. His life, work and legacy are set out in this four section handbook which provides orientation in what is currently known about the man, his affinities and character, his work and its impact. The volume offers a summary of research up until now, as well as a basis for further investigation. Comprehensive indexes and literature sources mean it can be used as a (...) work of reference whose articles can be separately or integrally understood. Writing from their different perspectives, philosophy and history scholars along with Protestant and Catholic theologians all help paint this portrait from their different perspectives. German description: Das Thomas Handbuch bietet eine Darstellung von Leben, Werk und Wirkung von Thomas von Aquin, dem wohl bedeutendsten Vertreter der scholastischen Philosophie und Theologie in interdisziplinarer und internationaler Perspektive.

Every educational system requires some kind of management and control. This is particularly true in the case of occupational education and dual apprenticeship. Nevertheless, the didactical value and the overall success of such kind of educational systems can vary considerably. Any educational system, any system of apprenticeship requires either some kind of coordination or some kind of co-operation. In Germany, despite the fact that there is a lot of rumors about the importance of cooperation for over a decade by now, (...) the well-known dual system of vocational education is firmly grounded on the management principle of co-ordination. The control of the system ‘by plans’ apparently has proved to be the most adequate approach to its organization and management structures. Starting from the idea of a duality which is characterized by its didactical dimension, the set of qualities needed for this purpose can be illustrated by following the logic of different didactical approaches in vocational education.

A theory of the transfinite Tarskian hierarchy of languages is outlined and compared to a notion of partial truth by Kripke. It is shown that the hierarchy can be embedded into Kripke's minimal fixed point model. From this results on the expressive power of both approaches are obtained.

The Qing dynasty scholar Liu Yuan (1768-1856) developed a unique system of thought, merging Confucian learning with ideas and practices from Daoism and Buddhism, and was eventually venerated as the founding patriarch of an influential movement combining the characteristics of a scholarly circle and a religious society. Liu Yuan, a native of Sichuan, was an outstanding Confucian scholar whose teachings were commonly referred to as Liumen (Liu School). Assisted by his close disciples, Liu edited a Daoist ritual canon titled Fayan (...) huizuan (Compendium of Ritual Words). Daoist priests affiliated with the Liumen community and using the Fayan huizuan canon in their rituals constituted an independent liturgical branch of Daoism, which is still extant and known under the name of "Fayan tan" (Altar of Ritual Words). Following a comprehensive description of the Liumen tradition, the volume by Volker Olles discusses the compilation history of the Fayan huizuan canon, the lineage of the Fayan tan priests, as well as the temporal framework of their liturgy. The main part of the volume consists of a detailed study of the ritual canon, identifying its textual sources and describing its pantheon, the influence of the Liumen ideology on its texts, as well as the function and performance of its rituals in contemporary religious practice. Furthermore concluding thoughts about the Fayan tan tradition's role in present-day Sichuan constitute the epilogue. By showing how members of the Confucian elite were involved in the evolution of modern Daoism, this study sheds light on hitherto obscure or poorly understood aspects of the intellectual and spiritual culture of Southwest China.

Summary The non-statement view of scientific theories contains a new conception of theoreticity: A function is „T-theoretical if T must be presupposed for its calculation. On the basis of this conception some philosophers came to the conclusion that scientific theories are not empirically testable because they contain T-theoretical functions. It is claimed that the attempt to test them ends in a circularity: The test of T presupposes T itself.
