In its first part, this paper shows why a recently made attempt to reduce the special theory of relativity to Newtonian kinematics is bound to fail. In the second part, we propose a differentiated notion of incommensurability which enables us to amend the contention that the special theory of relatively and Newtonian kinematics are “incommensurable”.

Philipp W. Balsiger / Rudolf Kötter Die Kultur moderner Wissenschaft am Beispiel Albert Einstein Für alle, die über den Tellerrand der Physik EInsteins blicken wollen Albert Einstein ist ein wissenschaftshistorisches Musterbeispiel dafür, wie wissenschaftliche Kulturleistungen bei der Entwicklung neuer Theorien, in persönlichen Netzwerken und im Zusammenhand mit philosophischem Denken entstehen. Dieses Buch enthält Beiträge von Physikern, Philosophen und Wissenschaftshistorikern, die überraschend vielseitigen Facetten der physikalischen Kultur am Beispiel Albert Einsteins zusammentragen: von den Paradigmenwechseln des Raum- Zeitverständnisses über die Philosophie (...) in der Physik bis hin zur Bildungs- und Popularisierungskultur, die mit seinem Wirken verbunden ist.

This article analyzes and compares the dynamically changing outcomes of anti-sweatshop campaigns in France and Switzerland through a qualitative comparative case study using interviews and analysis of firsthand and secondary data. In both countries, some targeted firms made early concessions and later withdrew from those concessions. To explain these changing outcomes over time, the article develops a perspective that puts emphasis on interaction phases and highlights corporate strategic responses to anti-sweatshop movement demands. Analyzing those responses as driven by legitimacy contests (...) between companies and activists, the study explains why anti-sweatshop movements had significant outcomes early on and shows the mechanisms that allowed firms to withdraw from initial concessions at a later stage. In the course of changing interaction dynamics and contexts, companies developed strategies building on competing sources of legitimacy to circumvent movement demands. The companies thereby compensated for the legitimacy losses inflicted by their withdrawal from earlier concessions and the legitimacy deficits of other solutions. The analysis reveals three strategies firms used to achieve and compensate legitimacy and discusses their contextual combination comparing the two cases: inter-firm cooperation, ethical product labels originating in collaborations with competing social movement actors, and publicly fighting back against campaign makers.

I present a formal theory of the logic and aboutness of imagination. Aboutness is understood as the relation between meaningful items and what they concern, as per Yablo and Fine’s works on the notion. Imagination is understood as per Chalmers’ positive conceivability: the intentional state of a subject who conceives that p by imagining a situation—a configuration of objects and properties—verifying p. So far aboutness theory has been developed mainly for linguistic representation, but it is natural to extend it to (...) intentional states. The proposed framework combines a modal semantics with a mereology of contents: imagination operators are understood as variably strict quantifiers over worlds with a content-preservation constraint.

Unification was originally introduced in automated deduction and term rewriting, but has recently also found applications in other fields. In this article, we give a survey of the results on unification obtained in two closely related, yet different, application areas of unification: description logics and modal logics.

Unlike the first English translation in 1974, this edition contains the text corresponding to Brentano's original 1874 edition.

We propose a new account of indicative conditionals, giving acceptability and logical closure conditions for them. We start from Adams’ Thesis: the claim that the acceptability of a simple indicative equals the corresponding conditional probability. The Thesis is widely endorsed, but arguably false and refuted by empirical research. To fix it, we submit, we need a relevance constraint: we accept a simple conditional 'If φ, then ψ' to the extent that (i) the conditional probability p(ψ|φ) is high, provided that (ii) (...) φ is relevant for ψ. How (i) should work is well-understood. It is (ii) that holds the key to improve our understanding of conditionals. Our account has (i) a probabilistic component, using Popper functions; (ii) a relevance component, given via an algebraic structure of topics or subject matters. We present a probabilistic logic for simple indicatives, and argue that its (in)validities are both theoretically desirable and in line with empirical results on how people reason with conditionals.

Die Idee zu der in diesem Band dokumentierten Tagung ist im Rahmen des disziplinübergreifenden Nachwuchswissenschaftsnetzwerkes THESIS entstanden. Der Dialog über die fachlichen und disziplinären Grenzen hinweg hat bei THESIS seit dessen Gründung im Jahre 1990 stets einen großen Raum eingenommen. Anderen Fächern Respekt und Interesse entgegenzubringen und sich nicht von stereotypen Vorurteilen leiten zu lassen, ist konstitutiver Bestandteil im Selbstverständnis des Netzwerkes. Selbstverständlich gibt es in einem solchen Verbund eine Reihe von Gelegenheiten (darunter auch den einen oder anderen entwicklungsfördernden Konflikt), (...) das eigene Bild vom Anderen und das andere Bild vom Eigenen zur Sprache zu bringen und zu hinterfragen. Auf der Basis dieser bestehenden Kommunikationsstrukturen trafen sich am 11. Oktober 2003 in Göttingen 12 junge Wissenschaftlerinnen und Wissenschaftler zwischen, über und auch auf den Grenzen ihrer eigenen Herkunftsdisziplinen, um den Trendbegriff [alpha]Transdisziplinarität" auf seine Substanz zu prüfen.

The Description Logic Handbook covers all aspects of the research in the field of knowledge representation. Written by some of the most prominent researchers in the field, and covering the basic technical material and implementational aspects, it is both a unique reference and a self-study guide.

Tractatus 4.024 inspired the dominant semantics of our time: truth-conditional semantics. Such semantics is focused on possible worlds: the content of p is the set of worlds where p is true. It has become increasingly clear that such an account is, at best, defective: we need an ‘independent factor in meaning, constrained but not determined by truth-conditions’ (Yablo 2014, p. 2), because sentences can be differently true at the same possible worlds. I suggest a missing comment which, had it been (...) included in the Tractatus, would have helped semantics get this right from the start. This is my 4.0241: ‘Knowing what is the case if a sentence is true is knowing its ways of being true’: knowing a sentence’s truth possibilities and what we now call its topic, or subject matter. I show that the famous ‘fundamental thought’ that ‘the “logical constants” do not represent’ (4.0312) can be understood in terms of ways-based views of meaning. Such views also help with puzzling claims like 5.122: ‘If p follows from q, the sense of “p” is contained in the that of “q”’, which are compatible with a conception of entailment combining truth-preservation with the preservation of topicality, or of ways of being true.

Im Zentrum der 1874 erschienenen bewußtseinspsychologischen Abhandlungen Brentanos steht die Beschreibung und Analyse des Psychischen. Damit bahnte sich jene Abwendung von der sensualistischen Tradition der philosophischen Bewußtseinslehre an, die in der Phänomenologie Edmund Husserls vollendet wurde.

When one thinks—knows, believes, imagines—that something is the case, one’s thought has a topic: it is about something, towards which one’s mind is directed. What is the logic of thought, so understood? This book begins to explore the idea that, to answer the question, we should take topics seriously. It proposes a hyperintensional account of the propositional contents of thought, arguing that these are individuated not only by the set of possible worlds at which they are true, but also by (...) their topic: what they are about. The book then builds epistemic, doxastic, probabilistic, and conditional logics based on this view. It applies them to issues ranging from dogmatism, scepticism, and epistemic fallibilism, to imagination and suppositional reasoning, belief revision, framing effects, and the acceptability of indicative conditionals.

Timothy Williamson has defended the claim that the semantics of the indicative ‘if’ is given by the material conditional. Putative counterexamples can be handled by better understanding the role played in our assessment of indicatives by a fallible cognitive heuristic, called the Suppositional Procedure. Williamson’s Suppositional Conjecture has it that the Suppositional Procedure is humans’ primary way of prospectively assessing conditionals. This paper raises some doubts on the Suppositional Procedure and Conjecture.

Description logics are a family of knowledge representation formalisms that are descended from semantic networks and frames via the system Kl-one. During the last decade, it has been shown that the important reasoning problems (like subsumption and satisfiability) in a great variety of description logics can be decided using tableau-like algorithms. This is not very surprising since description logics have turned out to be closely related to propositional modal logics and logics of programs (such as propositional dynamic logic), for which (...) tableau procedures have been quite successful.Nevertheless, due to different underlying institutions and applications, most description logics differ significantly from run-of-the-mill modal and program logics. Consequently, the research on tableau algorithms in description logics led to new techniques and results, which are, however, also of interest for modal logicians. In this article, we will focus on three features that play an important rôle in description logics (number restrictions, terminological axioms, and role constructors), and show how they can be taken into account by tableau algorithms.

We need to understand the impossible. Francesco Berto and Mark Jago start by considering what the concepts of meaning, information, knowledge, belief, fiction, conditionality, and counterfactual supposition have in common. They are all concepts which divide the world up more finely than logic does. Logically equivalent sentences may carry different meanings and information and may differ in how they're believed. Fictions can be inconsistent yet meaningful. We can suppose impossible things without collapsing into total incoherence. Yet for the leading philosophical (...) theories of meaning, these phenomena are an unfathomable mystery. To understand these concepts, we need a metaphysical, logical, and conceptual grasp of situations that could not possibly exist: Impossible Worlds. This book discusses the metaphysics of impossible worlds and applies the concept to a range of central topics and open issues in logic, semantics, and philosophy. It considers problems in the logic of knowledge, the meaning of alternative logics, models of imagination and mental simulation, the theory of information, truth in fiction, the meaning of conditional statements, and reasoning about the impossible. In all these cases, impossible worlds have an essential role to play. (shrink)

Behaviourism is the view that preferences, beliefs, and other mental states in social-scientific theories are nothing but constructs re-describing people's behaviour. Mentalism is the view that they capture real phenomena, on a par with the unobservables in science, such as electrons and electromagnetic fields. While behaviourism has gone out of fashion in psychology, it remains influential in economics, especially in ‘revealed preference’ theory. We defend mentalism in economics, construed as a positive science, and show that it fits best scientific practice. (...) We distinguish mentalism from, and reject, the radical neuroeconomic view that behaviour should be explained in terms of brain processes, as distinct from mental states. (shrink)

Pets are truly great companions. Some individuals feel that owning a pet can help them prepare for a growing family by giving them a taste of what it would be like to have children. This study also looks into the psychological well-being and life experiences of LGBT fur parents. Employing the Interpretative Phenomenological Analysis, the findings of this study were: (1) With the presence of fur babies, participants had the ease to overcome stressful events, especially the ones that affect their (...) mental health. With these, they have the desire to take care of their fur babies under all circumstances because they see their fur babies as family members. Fur babies are excellent sources of motivation, confidence, and happiness for fur parents. They are treated as family members because they contribute to the mental and emotional aspects of fur parents. Moreover, the majority of respondents valued their pets far more than their actual family members, however, some didn't spend as much time with their relatives and friends. This study comes to the conclusion that a stronger bond with one's dog was also linked to higher anxiety about being unloved and rejected by family members and people surrounding us, which was linked to a heavier impact on one's psychological well-being. In reality, fur parents, especially LGBT parents, offer their fur babies a lot of love and attention compared to other things. (shrink)

Feature logics are the logical basis for so-called unification grammars studied in computational linguistics. We investigate the expressivity of feature terms with negation and the functional uncertainty construct needed for the description of long-distance dependencies and obtain the following results: satisfiability of feature terms is undecidable, sort equations can be internalized, consistency of sort equations is decidable if there is at least one atom, and consistency of sort equations is undecidable if there is no atom.

We introduce a “reason-based” framework for explaining and predicting individual choices. It captures the idea that a decision-maker focuses on some but not all properties of the options and chooses an option whose motivationally salient properties he/she most prefers. Reason-based explanations allow us to distinguish between two kinds of context-dependent choice: the motivationally salient properties may (i) vary across choice contexts, and (ii) include not only “intrinsic” properties of the options, but also “context-related” properties. Our framework can accommodate boundedly rational (...) and sophisticatedly rational choice. Since properties can be recombined in new ways, it also offers resources for predicting choices in unobserved contexts. (shrink)

Franz Brentano (1838-1917) is a key figure in the development of Twentieth Century thought. It was his work that set Husserl on to the road of phenomenology and intentionality, that inspired Meinong's theory of the object which influenced Bertrand Russell, and the entire Polish school of philosophy. ^Descriptive Psychology presents a series of lectures given by Brentano in 1887; they were the culmination of his work, and the clearest statement of his mature thought. It was this later period which (...) proved to be so important in the work of his student, Husserl. This is the first English translation of his work. Benito Muller has added a concise introduction which places Brentano within the history of philosophy and psychology, and locates his influence in contemporary thought. (shrink)

Which rules for aggregating judgments on logically connected propositions are manipulable and which not? In this paper, we introduce a preference-free concept of non-manipulability and contrast it with a preference-theoretic concept of strategy-proofness. We characterize all non-manipulable and all strategy-proof judgment aggregation rules and prove an impossibility theorem similar to the Gibbard--Satterthwaite theorem. We also discuss weaker forms of non-manipulability and strategy-proofness. Comparing two frequently discussed aggregation rules, we show that “conclusion-based voting” is less vulnerable to manipulation than “premise-based voting”, (...) which is strategy-proof only for “reason-oriented” individuals. Surprisingly, for “outcome-oriented” individuals, the two rules are strategically equivalent, generating identical judgments in equilibrium. Our results introduce game-theoretic considerations into judgment aggregation and have implications for debates on deliberative democracy. (shrink)

Expanding on the theory of ethics first posited by Brentano in The Origin of our Knowledge of Right and Wrong this re-issued work, first published posthumously in 1952, is based on series of lectures on practical philosophy, given at the university of Vienna from 1876 to 1894. The English-speaking reader will find it interesting to examine the step-by-step development of Brentano’s ethical theory, his extensive critique of British moral philosophers, and his unusually detailed section on casuistry.

First published in English in1966, _The True and The Evident_ is a translation of Franz Brentano’s posthumous _Wahrheit und Evidenz_, edited by Oscsar Kraus. The book includes Brentano’s influential lecture "On the Concept of Truth", read before the Vienna Philosophical Society, a variety of essays, drawn from the immense wealth of Brentano’s unpublished material, and letters written by him to Marty, Kraus Hillebrand, and Husserl. Brentano rejects the familiar versions of the "correspondence theory of truth" and proposes to define (...) the true in terms of the evident. In criticising the metaphysical assumptions presupposed by the correspondence theory, he sets forth a conception of language and reality that has subsequently become known as "reism". (shrink)

Public reason as a political ideal aims to reconcile reasonable disagreement; however, is public reason itself the object of reasonable disagreement? Jonathan Quong, David Estlund, Andrew Lister, and some other philosophers maintain that public reason is beyond reasonable disagreement. I argue this view is untenable. In addition, I consider briefly whether or not two main versions of the public reason principle, namely, the consensus version and the convergence version, need to satisfy their own requirements. My discussion has several important implications (...) for the debate on public reason. (shrink)

Den Plan, seine Untersuchungen zur Deskriptiven Psychologie in einem umfassenden Werk zur Darstellung zu bringen, hat Brentano nicht verwirklicht. Neben kleineren Schriften zu diesem Gedankenkreis sind aber die Kollegmanuskripte der 1887 bis 1891 unter wechselnden Titeln gehaltenen Wiener Vorlesungen zur Deskriptiven Psychologie erhalten.

Erstmals 1951 publiziert, bilden die Vorlesungen über die Grundlagen und den Aufbau der Ethik ein geschlossenes und harmonisches Ganzes. Der Band geht zurück auf ein im Wintersemester 1876 niedergeschriebenes Manuskript, das Brentano 1894 als Kolleg an der Universität Wien vortrug.

Unification in description logics has been proposed as a novel inference service that can, for example, be used to detect redundancies in ontologies. The inexpressive description logic EL is of particular interest in this context since, on the one hand, several large biomedical ontologies are defined using EL. On the other hand, unification in EL has been shown to be NP-complete and, thus, of considerably lower complexity than unification in other description logics of similarly restricted expressive power. However, EL allows (...) the use of the top concept, which represents the whole interpretation domain, whereas the large medical ontology SNOMED CT makes no use of this feature. Surprisingly, removing the top concept from EL makes the unification problem considerably harder. More precisely, we will show that unification in EL without the top concept is PSPACE-complete. In addition to the decision problem, we also consider the problem of actually computing EL−⊤-unifiers. (shrink)

Zusammenfassung Der dargelegte Befund deutet darauf hin, daß es in Konstantinopel wie in Rom und anderen Provinzmetropolen zahlreiche Statuen hoher Beamter und Würdenträger gab. Allerdings fehlt ein entsprechender Befund für die Regierungszeit Konstantins d. Gr.; erst unter der Regierung Konstantius' II. lassen sich die ersten Beamtenstatuen feststellen. Das mag am Zufall der Überlieferung liegen, deckt sich aber immerhin damit, daß erst unter diesem Kaiser der Rahmen für eine breite magistratische Repräsentation gegeben war. Unter Konstantius II. wurde der Konstantinopler Senat zahlenmäßig (...) beträchtlich erweitert, zudem gleichberechtigt neben den römischen Senat gestellt, wurde das Amt des Stadtpräfekten eingeführt und, wie Paul Speck gezeigt hat, zugleich die Allpräsenz des Gründerkaisers Konstantin im Stadtbild relativiert, so daß überhaupt erst die Grundlagen für die öffentliche Repräsentation der Senatsaristokratie gegeben waren. Hatte Konstantin die nach ihm benannte Stadt zunächst als Residenzstadt errichtet, deren Bauten und Ausstattung ganz auf seine Person ausgerichtet waren, so schuf sein Sohn Konstantius die Voraussetzungen für die Entwicklung einer selbstbewußten Senatsaristokratie und einer entsprechenden Präsenz im Stadtbild. Die wenigen Indizien deuten darauf hin, daß sich die Statuen dieser Würdenträger, sofern es sich um senatorische Beamte handelte, beim Senat am Augusteion befanden. Stets dürfte es sich dabei um ‚einfache’ Statuen gehandelt haben, die allenfalls vergoldet waren, um bronzene Statuen oder um solche aus Marmor, die den Beamten in der Toga mit seinen Insignien zeigten. Seit dem fünften Jahrhundert läßt sich beobachten, daß eine kleine Gruppe einflußreicher Beamter und Heerführer entweder durch eine Vielzahl verschiedener Bildnisse an verschiedenen Orten oder aber durch die wesentlich aufwendigere Denkmalform eines Reiterstandbilds an prominenten Orten geehrt wird. Nie jedoch fand sich die Statue eines Nichtkaisers auf einem Ehrenbogen oder einer Säule, von denen es in Konstantinopel so viele gab. Diese blieben dem Kaiser und seiner Familie vorbehalten, der so im Denkmal den Abstand zu den aufwendigen Monumenten einflußreicher Personen wahren und auch erhöhen konnte. Doch beschränkte sich das kaiserliche Denkmal nicht nur auf einfache Ehrensäulen. Mehrfach sind Gruppen von Ehrensäulen überliefert, die städtebaulich an zentralen Stellen plaziert wurden. Zudem begegnet in der Spätantike zum erstenmal die Reiterstatue auf einem Säulenmonument, werden also zwei zunächst verschiedene Monumentformen miteinander verbunden (Abb. 7). Diese für die Spätantike typische Potenzierung der Wirkungsstrukturen und die Kombination bislang verschiedener Repräsentationsformen des imperialen Monuments ist wohl auch Folge des Konkurrenzdrucks durch allmächtige Militärs, die ihrerseits solche Selbstdarstellungsmodi aufgriffen. Die Kaiserdenkmäler bestimmen bis heute unser Bild von der Stadt Konstantinopel und lassen bisweilen vergessen, daß sie vor dem Hintergrund zahlreicher kleinerer Denkmäler hochrangiger Beamter errichtet wurden, unter denen einige so aufwendig waren, daß sie den Kaiser zum Aufgriff neuer, bislang noch nicht dagewesener Monumentformen zwangen.

Franz Brentano is recognised as one of the most important philosophers of the late nineteenth and early twentieth centuries. This work, first published in English in 1988, besides being an important contribution to metaphysics in its own right, has considerable historical importance through its influence on Husserl’s views on internal time consciousness. The work is preceded by a long introduction by Stephan Körner in collaboration with Brentano’s literary executor Roderick Chisholm. It is translated by Barry Smith.
