The present work takes the decease of Horst Wessel as an opportunity to present and honour his work (and that of his group), which has not received the attention it deserves. The focus will be on works which might not be sufficiently well-known. Wessel was, as we aim to show, familiar with the international debate concerning logical and philosophical issues and strived to solve them by considering theories of logical consequence, a non-traditional theory of predication and the theory (...) of logical terms, all of which he developed in joint work with Alexander Sinowjew. Wessel had to significantly refine these theories in order to formulate his criticism towards alternative logics and to apply the theories to a treatment of intensional contexts. He was vehemently opposed to approaches which revised fundamental laws of classical logic. Questions concerning the history of Philosophy are addressed in Wessel’s criticism of the Kantian antinomies of pure reason, in Wessel’s contributions to the problem of universals and his analyses of fatalism, tychism and antifatalism.

Ioannis Spatharakis has produced a book about the iconography of seventy-three painted churches of Crete. Given the lack of an exhaustive photographic publication of the Byzantine wall paintings of the island and the relatively few monographs on individual churches, in the past forty years scholars have attempted to compile synthetic works with mixed results. Three other volumes have dealt with Cretan frescoes prior to Spatharakis's book reviewed here: K. D. Kalokyris, The Byzantine Wall Paintings of Crete (New York, 1973); Manfred (...) Bissinger, Kreta. Byzantinische Wandmalerei. Münchener Arbeiten zur Kunstgeschichte und Archäologie 4 (Munich, 1996); and to a lesser degree Klaus Gallas, Klaus Wessel, and Manolis Borboudakis, Byzantinisches Kreta. Studium und Reise. (Munich, 1983) which is a learned, comprehensive travel guide. (shrink)

Appraisal theories of emotion have had a strong impact on the development of theory and experimental research in the domain of the affective sciences. While there is generally a high degree of convergence between theorists in this tradition, some central issues are open to debate. In this contribution three issues have been chosen for discussion: (a) varieties of relevance detection, (b) varieties of valence appraisal, and (c) sequential-cumulative effects of appraisal results. In addressing these issues, new theoretical ideas are suggested (...) and an update of recent research on the sequence of appraisal processes is provided. Special emphasis is placed on nonverbal signatures of appraisal processes. (shrink)

Entailment relations, introduced by Scott in the early 1970s, provide an abstract generalisation of Gentzen’s multi-conclusion logical inference. Originally applied to the study of multi-valued logics, this notion has then found plenty of applications, ranging from computer science to abstract algebra. In particular, an entailment relation can be regarded as a constructive presentation of a distributive lattice and in this guise it has proven to be a useful tool for the constructive reformulation of several classical theorems in commutative algebra. In (...) this paper, motivated by these concrete applications, we state and prove a cut-elimination result for inductively generated entailment relations. We analyse some of its consequences and describe the existing connections with analogous results in the literature. (shrink)

Foundations of Dialectical Psychology is a compilation of the writings of Klaus F. Riegel on dialectical psychology. The book presents chapters discussing such topics as the dialectics of human development; history of dialectical psychology; temporal organization of dialogues; and the analysis of the concept of crisis and its underlying philosophical model and ideology. Psychologists and students will find the book invaluable.

Diagnosing emotion disturbances should be informed by current knowledge about normal emotion processes. I identify four major functions of emotion as well as sources for potential dysfunctions and suggest that emotions should only be diagnosed as pathological when they are clearly dysfunctional, which requires considering eliciting events, realistic person-specific appraisal patterns, and adaptive responses or action tendencies. Evidence from actuarial research on the reported length of naturally occurring emotion episodes (including potential determinants) illustrates appropriateness criteria for the clinical evaluation of (...) emotion duration—an essential element in the DSM-5 symptom catalogue for major depression episodes, especially in bereavement. The need for more actuarial evidence on normal emotion responses and its consideration by the clinical community is highlighted. (shrink)

Although still young when he wrote this book, Voegelin already demonstrates his singular analytical capacity as well as his ability to put political phenomena into a new perspective.

Two experiments were conducted to investigate the roles of covariation and of causality in people's readiness to believe a conditional. The experiments used a probabilistic truth-table task (Oberauer & Wilhelm, 2003) in which people estimated the probability of a conditional given information about the frequency distribution of truth-table cases. For one group of people, belief in the conditional was determined by the conditional probability of the consequent, given the antecedent, whereas for another group it depended on the probability of the (...) conjunction of antecedent and consequent. There was little evidence that covariation, expressed as the probabilistic contrast or as the pCI rule (White, 2003), influences belief in the conditional. The explicit presence of a causal link between antecedent and consequent in a context story had a weak positive effect on belief in a conditional when the frequency distribution of relevant cases was held constant.

Eine wissenschaftliche Methode oder Verfahrensweise, die man als ›die‹ philosophisch-wissenschaftliche Methode des Aristoteles bezeichnen könnte, gibt es nicht. Vielmehr ist es so, dass Aristoteles in unterschiedlichen Kontexten auch unterschiedliche Verfahren zur Anwendung bringt. Wenn man daher von einer einheitlichen philosophisch-wissenschaftlichen Methode bei Aristoteles sprechen wollte, so könnte man dies nur der Analogie nach tun.

Das Bild des »goldenen Berges« geht zurück auf geographische Angaben und Beschreibungen, die in der Antike als glaubwürdig angesehen wurden. In der Literatur illustriert die Metapher das Bedeutungsspektrum von Reichtum, Wohlergehen, Überfluss und Glück, spricht aber auch Warnungen aus. Dagegen werden in den philoso-phischen Interpretationen vor allem Konstitutionsprobleme des Fiktiven, auch der entia rationis, thematisiert. Die Metapher exemplifiziert Objekte, die logisch möglich sind, aber nicht wirk-lich existieren. In der Philosophiege-schichte – bis in die aktuellen Analysen der non-existent objects hinein – (...) wurde das Bild des »goldenen Berges« daher stets mit der Frage verbunden, welche Instanzen wir als »wirklich«, »möglich« oder »unmöglich« rechtfertigen kön-nen. Als Beispiel spiegelt die Metapher die Transformationen, in denen sich das Wirklichkeitsverständnis der philoso-phischen Tradition wie in einem Prisma gebrochen hat. (shrink)

I strongly endorse many of the suggestions made by the authors of the extremely useful reviews in this issue. In particular, the need to identify the complex causal mechanisms underlying the major health risk factors requires urgent attention of the research community. I suggest considering the important role of emotional disturbances as contributors to health risks given the empirically established comorbidity between mental and somatic illness. Better knowledge of these mechanisms is an essential prerequisite to develop tailored personalized prevention and (...) intervention programs, including reliable and valid assessment of deficits.

The purpose of this qualitative study was to examine the perceptions related to ethics and cheating among a representative sample of primarily female undergraduate students, compared to trends reported in the literature. Focus groups were organized to discuss nine scripted questions. Transcripts and audiotapes were analyzed and four main themes emerged: demographics of those who cheat, students’ perceptions of cheating, the role of technology in cheating, and consequences of cheating, including students’ attitudes and behaviors related to reporting cheating incidents. Bandura’s (...) Social Cognitive Theory served as the theoretical framework to understand students’ varying perceptions of and justification for cheating, as well as the dynamics of honor code violations, via group discussion. Viewpoints on cheating were regularly discussed and contradictory views were identified related to frequency and justification for cheating. Utilizing the constant comparative method, students mentioned time limitations, and pressure from peers, parents, and professors as reasons to cheat. They also discussed pressures to achieve high grades for acceptance into graduate programs. Students were also reluctant to report their classmates for cheating incidents. Repeated and comprehensive education on ethical behavior is warranted. (shrink)

Alongside the analogy between maximal ideals and complete theories, the Jacobson radical carries over from ideals of commutative rings to theories of propositional calculi. This prompts a variant of Lindenbaum’s Lemma that relates classical validity and intuitionistic provability, and the syntactical counterpart of which is Glivenko’s Theorem. The Jacobson radical in fact turns out to coincide with the classical deductive closure. As a by-product we obtain a possible interpretation in logic of the axioms-as-rules conservation criterion for a multi-conclusion Scott-style entailment (...) relation over a single-conclusion one.

The goal of this paper is an interpretation of Aristotle's modal syllogistics closely oriented on the text using the resources of modern modal predicate logic. Modern predicate logic was successfully able to interpret Aristotle's assertoric syllogistics uniformly , that is, with one formula for universal premises. A corresponding uniform interpretation of modal syllogistics by means of modal predicate logic is not possible. This thesis does not imply that a uniform view is abandoned. However, it replaces the simple unity of the (...) assertoric by the complex unity of the modal. The complexity results from the fact that though one formula for universal premises is used as the basis, it must be moderated if the text requires . Aristotle introduces his modal syllogistics by expanding his assertoric syllogistics with an axiom that links two apodictic premises to yield a single apodictic sentence . He thus defines a regular modern modal logic. By means of the regular modal logic that is thus defined, he is able to reduce the purely apodictic syllogistics to assertoric syllogistics. However, he goes beyond this simple structure when he looks at complicated inferences. In order to be able to link not only premises of the same modality, but also premises with different modalities, he introduces a second axiom, the T-axiom, which infers from necessity to reality or - equivalently - from reality to possibility. Together, the two axioms, the axiom of regularity and the T-axiom, define a regular T-logic. It plays an important role in modern logic. In order to be able to account for modal syllogistics adequately as a whole, another modern axiom is also required, the so-called B-axiom. It is very difficult to decide whether Aristotle had the B-axiom. The two last named axioms are sufficient to achieve the required contextual moderation of the basic formula for universal propositions. (shrink)

Smooth social interaction requires interindividual coordination. This Theory Section addresses the nature of the processes involved and the potential dangers of malfunctioning coordination. In her invited article, Butler provides a general overview of the processes involved, including interpersonal synchronisation, and advocates a dynamic systems framework for further research. In their commentary, Carré and Cornejo concur in principle but highlight the importance of the meaning attributed to the spontaneous expressive movements in naturally occurring interactions and the nature of the respective social (...) situations. Suhay, in her commentary from a political science perspective, highlights the need for synergy based on social coordination for successful democratic governing. In commenting on the problem of political polarisation because of malfunctioning social coordination, introduced by Butler, Suhay adds the important role played by social identity and emotion. Of particular importance are affective reactions based on “evaluative biases” in favour of information that bolsters one's views and rejection of information that challenges them. I conclude this editorial by referring to recent data on affective polarisation, pleading for more multidisciplinary research on the phenomenon, and arguing for a more substantial contribution from the cognitive and emotion sciences. In particular, I outline the “predictive coding” framework and the potential contributions from emotion science. (shrink)

Gastrulation is the process of early development that reorganizes cells into the three fundamental tissue types of ectoderm, mesoderm, and endoderm. It is a coordinated series of morphogenetic and molecular changes that exemplify many developmental phenomena. In this review, we explore one of the classic developmental systems, the sea urchin embryo, where investigators from different backgrounds have converged on a common interest to study the origin, morphogenesis, and developmental regulation of the endoderm. The sea urchin embryo is remarkably plastic in (...) its developmental potential, and the endoderm is especially instructive for its morphological and molecular responsiveness to inductive cell interactions. We start by examining and integrating the several models for the morphogenetic mechanisms of invagination and tissue elongation, the basic processes of endoderm morphogenesis in this embryo. We next critique the proposed mechanisms of inductive gene regulation in the endoderm that exemplifies a concept of modular transcriptional regulation. Finally, we end with an examination of the current molecular models to explain cell fate determination of the endoderm. Recent progress at the molecular level should soon allow us to explain the seminal experimental observations made in this embryo over a hundred years ago.
