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.

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.

The book provides a thematic account of the changing political thought of critical theorists from Adorno to Habermas and Honneth. Its purpose is to establish the relevance of this tradition for contemporary political theory and philosophy.

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)

Is a Muslim still a Muslim when he crashes airplanes into the twin towers? Any serious theory of multiculturalism has to deny that Islam could ever come to justify suicide bombing and terrorism. My thesis is that none of the contemporary multicultural theories manages to do so, or at least not without collapsing into a Kantian conception of personal autonomy and, consequently, into some standard version of liberalism. Communitarianism, trying to demonstrate that fundamentalism has nothing to do with the true (...) and authentic Islam and that it does not take into account the pluralism prevailing in Islam, has to moralize Islam. A Humean position, which takes Islamic fundamentalism to be merely a pathology, the product of resentment and western neocolonialism, eventually could come to the conclusion that good and upright Muslims today cannot help but become suicide bombers. Liberal multiculturalism, considering identity to be a matter of choice, must suppose that an active agent with self-knowledge is by definition a responsible person with a moral identity. In conclusion, multiculturalism, in its effort to make the good identities prevail over the bad and the ugly identities, risks adopting some of the same righteous attitudes towards Islam as traditional liberalism.

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.

Against competing political theories of the integration of immigrants, we propose to reframe the relationship between the populations of host countries and arriving refugees in terms of a neo-Maussian theory of gift exchange. Using the example of the European refugee crisis of 2015 and the welcoming attitude of significant parts of German civil society, we argue that this particular situation should be understood as epitomizing the trend toward internal transnationalism. Increasingly, the “international” is becoming part and parcel of the “domestic” (...) sphere. Since Marcel Mauss was concerned with the question of how separate, culturally different communities can establish ties of solidarity and cooperation between each other, we use his work to answer key questions about the relations between international refugees and native citizens in their home countries: What are the expectations underlying gift-giving in the context of welcoming refugees? Should refugees feel obliged to repay the arrival gifts? How sh... (shrink)

It is shown that David Hilbert's formalistic approach to axiomaticis accompanied by a certain pragmatism that is compatible with aphilosophical, or, so to say, external foundation of mathematics.Hilbert's foundational programme can thus be seen as areconciliation of Pragmatism and Apriorism. This interpretation iselaborated by discussing two recent positions in the philosophy ofmathematics which are or can be related to Hilbert's axiomaticalprogramme and his formalism. In a first step it is argued that thepragmatism of Hilbert's axiomatic contradicts the opinion thatHilbert style (...) axiomatical systems are closed systems, a reproachposed by Carlo Cellucci. In the second section the question isdiscussed whether Hilbert's pragmatism in foundational issuescomes close to an a-philosophical ``naturalism in mathematics'' assuggested by Penelope Maddy. The answer is ``no'', because forHilbert philosophy had its specific tasks in the general projectto found mathematics. This is illuminated in the concludingsection giving further evidence for Hilbert's foundationalapriorism by discussing his ``axiom of the existence of mind'' andrelating it to the ``one and only axiom'' of the German algebraistof logic, Ernst Schröder, postulating the inherence of signs onthe paper.

Kultur ist die gesellschaftliche Form, die das menschliche Leben nicht nur zum Überleben, sondern zur Entfaltung seiner besten Kräfte benötigt. Ob die Kultur beides auch in Zukunft wird leisten können, erscheint fraglich. Volker Gerhardts programmatischer Entwurf zeigt, dass es die Aufgabe der Philosophie ist, Klarheit in die Verhältnisse zwischen den Leitbegriffen Natur, Kultur, Technik und Vernunft zu bringen. Seine These ist, dass es vornehmlich kulturelle Veränderungen sein müssen, durch die die drohende Katastrophe abgewendet werden kann. Und: Um wirksam zu (...) sein, muss eine solche kulturelle Erneuerung eine weltweite Perspektive haben – unter Wahrung der nationalen, regionalen und lokalen Traditionen. (shrink)

Scholars agree that Christology is at the center of the In Iohannis euangelium tractatus. In his exegesis of the Gospel of John, Augustine particularly highlights the human nature of the Incarnated, even as he integrates Trinitarian arguments (which he had developed earlier in his De trinitate) as a cornerstone of his homiletic teaching. This may have been important for the later reception of Augustine’s Trinitarian thought. Christology is clearly present throughout the various parts of the work. The differences between the (...) parts can be traced to the various contexts in which they were composed and/or delivered: e.g., the Anti-Donatist controversy that is behind the first sermons, and the Anti-Pelagian and Anti-Homean controversies that often fueled the later ones. Sometimes anti-heretical strategies are used as a crucial step for advancing the teaching of the preacher (not least because they can directly promote knowledge of the fundamentals of the faith), even if the heresy being opposed is of no immediate relevance or importance to the North Africa of Augustine’s day (e.g., that of the “Sabellians” or the “Apollinarians”). Surprisingly, the second half of the work (consisting as it does of shorter homilies or, better, drafts of homilies) contains various passages in which anti-heretical strategies were clearly pursued. It is particularly Augustine’s Anti-Pelagian strategy that provides us with clues regarding the historical context of this part of the work. (shrink)

The article addresses the following question: if an extensive period of globalization and also democratization after the fall of the Berlin Wall has been followed by populism, does this mean that there is something wrong with liberalism itself? Must liberalism be substituted by alternative economic and political concepts? The article presents three alternatives to liberalism that are supposed to counter populism: a new communitarianism, a renewal of the democratic project as much as novel conceptions of social justice. However, it takes (...) also into account positions that address the current crisis from within the liberal framework itself. (shrink)

) 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 first of two volumes brings together invited papers of the 32nd International Wittgenstein Symposium (Kirchberg/W. (Austria), 2009). The relation between language and the world was undoubtedly one if not the central issue in Wittgenstein's whole philosophical oeuvre. His one hundred and twentieth birthday provided an occasion for foregrounding this aspect of his work. A special workshop was dedicated to new aspects of Wittgenstein's Nachlass. In this volume Frank Cioffi, Peter Hacker, Ian Hacking, Roy Harris, Lars Hertzberg, Jaakko Hintikka, Marie (...) McGinn, Danièle Moyal-Sharrock, Hans Sluga among others provide substantial contributions on various aspects of Wittgenstein's writings such as the philosophy of mathematics, the problem of rule following or the relation between meaning and use.

The proof-theoretic results on axiomatic theories oftruth obtained by different authors in recent years are surveyed.In particular, the theories of truth are related to subsystems ofsecond-order analysis. On the basis of these results, thesuitability of axiomatic theories of truth for ontologicalreduction is evaluated.

In his new book on Pascal's Wager, Jeff Jordan argues that only the ‘Jamesian’ version of the wager argument, as he sees it presented in William James' essay The Will to Believe , constitutes a sound pragmatic argument in favour of theism, whereas Pascal's original wager argument is doomed to fail on various grounds. This article argues that Jordan's theory is untenable. The many-gods objection is used as an example: it is demonstrated that the Jamesian Wager argument too is powerless (...) to rebut this objection. (shrink)

The basis for the secrecy is equally apparent, being furnished by Kant a bit later: it could, he suggests, damage the repute of governments to take counsel in foreign affairs from their “subjects.” As a consequence, what can only be publicly executed ought to be agreed on previously in strict secrecy. The state may thus only “tacitly... summon its citizens” to “publicly discuss the general maxims of warfare and peacemaking”. Quite superfluously, a few lines later Kant expressly concedes that “no (...) particular agreement... in this particular point” is needed, corresponding as it does to the imperative of general “human reason.” The public status here openly endowed with secrecy thus has as its object nothing less than something morally and legally self-evident.

Im Rahmen einer Fallstudie ('Okonomische Theorie der Demokratie' von Anthony Downs) wird gezeigt, dass realwissenschaftliche Theorien, unabhangig davon, ob sie sozial- oder naturwissenschaftlicher Provenienz, in bezug auf ihre logische Struktur identisch sind. Mit der stringenten Anwendung des metatheoretischen Rekonstruktionskonzeptes des Strukturalismus auf eine politikwissenschaftliche Theorie wird ein Rahmen entwickelt, der es erlaubt, politikwissenschaftliche Theorien nicht nur praziser zu erfassen, sondern auch eine fundierte Klarung dessen zu erbringen, was eine politikwissenschaftliche Theorie sein kann.".
