Most formalisms for representing common-sense knowledge allow incomplete and potentially inconsistent information. When strong negation is also allowed, contradictory conclusions can arise. A criterion for deciding between them is needed. The aim of this paper is to investigate an inherent and autonomous comparison criterion, based on specificity as defined in [POO 85, SIM 92]. In contrast to other approaches, we consider not only defeasible, but also strict knowledge. Our criterion is context-sensitive, i. e., preference among defeasible rules is determined dynamically (...) during the dialectical analysis.We show how specificity can be defined in terms of two different approaches: activation sets and derivation trees. This allows us to get a syntactic criterion that can be implemented in a computationally attractive way. The resulting definitions may be applied in general rulebased formalisms. We present theorems linking both characterizations. Finally we discuss other frameworks for defeasible reasoning in which preference handling is considered explicitly. (shrink)

We characterize preservation of superstability and ω-stability for finite extensions of abelian groups and reduce the general case to the case of p-groups. In particular we study finite extensions of divisible abelian groups. We prove that superstable abelian-by-finite groups have only finitely many conjugacy classes of Sylow p-subgroups.

Kant’s revolutionary new approach to philosophy was accompanied by the introduction of a largely novel terminology. With the Kant-Lexikon, a lexical reference gives the modern reader access to his work on the basis of present-day editions and takes into account 20th century and contemporary research and advances in lexicology. The Kant-Lexikon includes 2395 entries authored by 221 scholars.

The use of the journal impact factor (JIF) as a measure for the quality of individual manuscripts and the merits of scientists has faced significant criticism in recent years. We add to the current criticism in arguing that such an application of the JIF in policy and decision making in academia is based on false beliefs and unwarranted inferences. To approach the problem, we use principles of deductive and inductive reasoning to illustrate the fallacies that are inherent to using journal (...) based metrics for evaluating the work of scientists. In doing so, we elaborate that if we judge scientific quality based on the JIF or other journal based metrics we are either guided by invalid or weak arguments or in fact consider our uncertainty about the quality of the work and not the quality itself.

In this paper, we will discuss Peter van Inwagen’s contribution to the epistemological debate about revealed peer disagreement. Roughly, this debate focuses on situations in which at least two participants disagree on a certain proposition based on the same evidence. This leads to the problem of how one should react rationally when peer disagreement is revealed. Van Inwagen, as we will show, discusses four possible reactions, all of which he rejects as unsatisfying. Our proposal will be to point to hidden (...) assumptions in van Inwagen’s reasoning and ask whether he is willing to reject at least one of these to get rid of the problem. In short, our thesis amounts to the following: Of the two epistemological claims, which we call “Weak” and “Full-blown Fallibilism”, van Inwagen cannot simultaneously accept the first and reject the latter, while this is what he seems to suggest. Revealing this potential dilemma for van Inwagen’s position will lead to a more detailed discussion of how “rationality”, “truth”, “evidence” and “justification” interrelate and how a closer look at their relation might help solving the puzzle of revealed peer disagreement.

Starting with the observation that transparency has become a concept so familiar that one hardly ever stops to consider the presuppositions and consequences of its usage, the chapter analyses transparency demands as a specific way of exercising power. By doing so, the author shows that the intrinsic logic of transparency leads to paradoxical effects. Any attempts to realize complete transparency undermine its own preconditions. As Vogelmann argues, instead of providing more visibility and clarity, transparency makes its objects “invisible” and the (...) intensification of transparency demands produces self-censorship. The chapter concludes that transparency claims undermine the distinction between the private and the public and threaten the individual autonomy. (shrink)

In this paper the structuralist approach of theory reconstruction is applied to International Trade Theory. In the basic element the universal laws of the theory are stated and the general concepts are defined in terms of three sets and seven functions. Ricardo’s Theory of Comparative Advantage and the Factor Proportions Theory by Heckscher and Ohlin are reconstructed as specialisations of the basic element. Two intratheoretical constraints are formulated in order to ensure the consistency of the theory. A number of empirical (...) studies are shown to be paradigmatic, successful or questionable applications of International Trade Theory. The reconstruction allows the assessment of the theory from a metatheoretical angle and illuminates the logical interdependencies of its components. (shrink)

All theories of critique rely on a – often implicit – description of the activity that doing critique is supposed to consist in. These “pictures of critique” frame all further distinctions and justifications in the debate about critique and critique’s normativity. After distinguishing three pictures of critique – measuring, disrupting and emancipating critique – I ask whether the theoretical reflection in which a certain conception of critique is elaborated is itself accurately captured by the picture of critique it employs. In (...) other words: Is the theoretical reflection of critique a critical activity according to its own picture of critique? I propose to call only those theories of critique critical theories the theoretical activity of which is a critical activity on their own picture of critique - which are surprisingly few. Most critical theories are thereby revealed to be rather traditional when it comes their own theorizing of critique. (shrink)

Although Amy Allen’s critique of contemporary Frankfurt School critical theory has been widely discussed, her concern for an adequate conceptualization of reason’s intertwinement with power has not received the attention it deserves. The article shows that the diagnosis of a too idealistic account of reason forms the backbone of Allen’s charges against Habermas, Honneth and Forst, before it discusses her criteria for an adequate conceptualization of the intertwinement of reason and power. It demonstrates that Allen’s attempt to formulate such a (...) conceptualization falls short of two of her own criteria, namely the basic commitments of essentially impure reason and radical self-reflexivity. Taking seriously Allen’s proposal for a radical self-reflexive genealogical critique would force her to question the very terms in which she formulates her critique of critical theory, namely the search for “normative foundations,” and the article sketches a way for doing so.

Was bedeutet die steile Karriere von Verantwortung (nicht nur) in der Philosophie, und welchen Preis zahlen wir dafür? Dass große Teile der modernen Philosophie ihr verfallen sind, so die zentrale These, bezahlt diese mit Blindheit für die theoretischen wie praktischen Auswirkungen von Verantwortung. Um sie zu analysieren, muss Verantwortung als diskursiven Operator verstanden werden, dessen Einheit im ambivalenten Selbstverhältnis der Verantwortung Tragenden liegt. Seine praktischen Auswirkungen werden exemplarisch in den Praktiken der Arbeit und der Kriminalität studiert, in denen das verantwortliche (...) Selbstverhältnis intensiviert und zugleich von der Voraussetzung substantieller Handlungsmacht entkoppelt wird. So hilft Verantwortung, eine unternehmerische Logik in die Selbstverhältnisse zunehmend entmachteter Lohnarbeiterinnen und »Arbeitsloser« einzuschmelzen sowie die Bürgerinnen aktiv in die präventiv gewendete Kriminalpolitik einer auf öffentliche Sicherheit fixierten Gesellschaft einzubinden. Die theoretischen Auswirkungen werden anhand der Genealogie von Verantwortung innerhalb der Philosophie analysiert, in der sich Verantwortung vom Instrument in der metaphysischen Debatte um Willensfreiheit zu einem eigenständigen moralischen Problem und schließlich zur Gewissheit wandelt, mit der andere philosophische Fragen erklärt werden. Fixpunkt aller Reflexionen bleibt das ambivalente verantwortliche Selbstverhältnis als aktiver Umgang mit dem Faktum des eigenen Unterwerfens – sowohl dem Unterworfen-sein als auch dem Unterwerfen Anderer. Das zum Faktum erklärte Unterwerfen erlaubt dem Subjekt, sich unabhängig von seiner tatsächlichen Handlungsmacht als souverän zu erleben, und bildet den verborgenen Kern des verantwortlichen Selbstverhältnisses. Weil Verantwortung aber zunehmen gebraucht wird, um die Bindungskraft von Normativität als ureigenes Gebiet der Philosophie zu explizieren, verleitet ihre Attraktivität dazu, diese Selbstobjektivierung zu übersehen oder zu leugnen und den praktischen Gebrauch der philosophischen Legitimierungen von Verantwortung auszublenden. Dagegen setzt dieses Buch eine diagnostische Kritik, die den Bann der Verantwortung wenn nicht bricht, so doch entlarvt. (shrink)

Prof. Dr. Frieder Otto Wolf, President of the Humanistischer Verband Deutschlands, provides an overview of the main currents of modern humanism in Germany. He describes the central stream of German humanism as practical, in that it combines the principled imperative to overcome all structures and situations in which people are not treated as human beings with seeking to widen the horizons of humane existence in the arts and sciences and in capabilities of leading a fulfilling life. This humanism compels (...) resort to other criteria than nature, such as those logical, emotive, cultural, in order to gauge the acceptability of value claims. The practical efforts to humanize society and widen human horizons requires engagement in public policy debates and social organizing and programming on consensus issues. Accordingly, the HVD works on such diverse issues as strengthening the rights to bodily integrity and sexual autonomy, preventing economic collapse, accommodating immigrants, protecting personal privacy, limiting the use of military force, building intra- and international peace, and exposing anti-humanist prejudice.

Political epistemology is the name of an ambitious task. In order to aptly conceptualise the internal relationship between truth and knowledge on one side, and politics and society on the other side, political epistemology must reformulate the concepts of epistemology and social and political theory. For the concept of knowledge, this task implies to consider the truth and the force of knowledge equally. Frieder Vogelmann shows in his book the far-reaching consequences of this endeavour: for the contemporary debate about (...) untruth in politics, for the possible forms of social critique, and for the reflection upon philosophy and its history.

In this article, three theses are proposed. The first is that ›force‹ and ›normativity‹ are not just two fundamental concepts in philosophy today but two paradigms: Each claims to structure how we view the world, to name what is specifically human and to determine the task of philosophy. Their confrontation repeats, according to the second thesis, the dispute between neo-Kantian normativism and life-philosophy in the 19th century, best captured by the concepts of ›life‹ and ›validity.‹ Third, the differences within this (...) repetition concern the position, status and nature of subjectivity: Whereas theories of validity in the 19th century are at least partially anti-subjectivist, and thus accused of being abstract, scholastic and hostile to ›life‹ by life-philosophy, today it is the paradigm of ›force‹ which regards the subject as a contingent result of forces. In contrast, contemporary normativism argues for the autonomy of a sovereign subject whose activity is the source of non-indifference in his or her world. (shrink)

Currently, the rise of science denialism is met by a new positivism that is equally detrimental for the natural and social sciences and humanities. Both paint an unrealistic picture of science in the singular, based on an idealist epistemology. In stark opposition, the article argues for a materialist epistemology that can support a realistic understanding of scientific practices by taking seriously their plurality, historicity and contextuality.

‘Post-truth’ is a failed concept, both epistemically and politically because its simplification of the relationship between truth and politics cripples our understanding and encourages authoritarianism. This makes the diagnosis of our ‘post-truth era’ as dangerous to democratic politics as relativism with its premature disregard for truth. In order to take the step beyond relativism and ‘post-truth’, we must conceptualise the relationship between truth and politics differently by starting from a ‘non-sovereign’ understanding of truth.

Most people would agree that we should behave and act in a responsible way. Yet only 200 years ago, ‘responsibility’ was only of marginal importance in discussions of law and legal practice, and it had little ethical significance. What is the significance of the fact that ‘responsibility’ now plays such a central role in, for example, work, the welfare state, or the criminal justice system? What happens when individuals are generally expected to think of themselves as ‘responsible’ agents? And what (...) are the consequences of the fact that the philosophical analysis of ‘responsibility’ focuses almost exclusively on conditions of agency that are mostly absent from real life? -/- In this book, Frieder Vogelmann demonstrates how large parts of philosophy have fallen under responsibility’s spell, and he uses a Foucauldian approach in an attempt to break it. The three axes of power, knowledge, and self are used in a detailed analysis of the practical regimes of labour (including the welfare state), criminality (including policing, punishment practices, and criminal proceedings), and philosophy, and of the two subject positions required by ‘responsibility’ – those of the attributors and bearers of responsibility – within them. The power relations between these positions, which Vogelmann carefully excavates from the grounds of our practices, reveal that the deck is stacked unevenly from the start. (shrink)

Although the various interpretations of Foucault’s model of critique often seem to differ only in minor details, they seriously diverge by situating critique on different levels of abstraction in Foucault’s work. Mapping interpretations of Foucault’s critique according to this criterion shows that none of them pays full attention to all three of Foucault’s methodological imperatives which he calls nihilism, nominalism and historicism. The article offers such a reading of Foucault’s critique, interpreting it as a diagnostic practice of prefigurative emancipation. The (...) task of diagnosing the present explains how Foucault’s critique functions as a philosophical practice, and by making explicit in which ways it emancipates us, it gives us reasons why we might be interested in doing critique like that.
