We link two concepts from the literature, namely hard sequences for the satisfiability problem sat and so‐called pseudo proof systems proposed for study by Krajíček. Pseudo proof systems are elements of a particular nonstandard model constructed by forcing with random variables. We show that the existence of mad pseudo proof systems is equivalent to the existence of a randomized polynomial time procedure with a highly restrictive use of randomness which produces satisfiable formulas whose satisfying assignments are probably hard to find.

Likert-scale surveys are frequently used in cross-cultural studies on leadership. Recent publications using digital text algorithms raise doubt about the source of variation in statistics from such studies to the extent that they are semantically driven. The Semantic Theory of Survey Response (STSR) predicts that in the case of semantically determined answers, the response patterns may also be predictable across languages. The Multifactor Leadership Questionnaire (MLQ) was applied to 11 different ethnic samples in English, Norwegian, German, Urdu and Chinese. Semantic (...) algorithms predicted responses significantly across all conditions, although to varying degree. Comparisons of Norwegian, German, Urdu and Chinese samples in native versus English language versions suggest that observed differences are not culturally dependent but caused by different translations and understanding. The maximum variance attributable to culture was a 5% unique overlap of variation in the two Chinese samples. These findings question the capability of traditional surveys to detect cultural differences. It also indicates that cross-cultural leadership research may risk lack of practical relevance. (shrink)

According to a common opinion, the word ‘semantics’ , derived from the Greek word semantikos , appeared for the first time, at least in modern times, in the book Essai de semantique, science de significations by M. J. A. Bréal . However, Quine says in his lectures on Carnap:As used by C. S. Peirce, “semantic” is the study of the modes of denotation of signs: whether a sign denotes its object through causal or symptomatic connection, or through imagery, or through (...) arbitrary convention and so on. This sense of semantic, namely a theory of meaning, is used also in empirical philology: empirical semantic is the study of historical changes of meanings of words.1For Bréal, semantics was a branch of general linguistics. In particular, semantics was occupied with so-called lexical meaning and its changes through time. Thus, semantics in this sense belonged to what was called “the diachronic treatment of language”. This tradition is fairly alive in contemporary linguistic theory. Quine’s description of the word ‘semantic’ in Peirce corresponds, which Quine explicitly states, to its use in philology. However, some linguists ascribe a more theoretical role to lingustic semantics. Karl Bühler is an example. In his Sprachtheorie he says that a theory of semantic functions of language is a part of theory of language.2 This account is to be found also among philosophers. It is also rather obvious that Peirce did not limit his semantic only to empirical studies. Linguists also use the word ‘semasiology’ instead of ‘semantics’; Bühler proposed the term ‘sematology’ for a general theory of symbols. (shrink)

The limiting of violence through state powers is one of the central projects of the modern age. Why then have recent centuries been so bloody? In Trust and Violence, acclaimed German intellectual and public figure Jan Philipp Reemtsma demonstrates that the aim of decreasing and deterring violence has gone hand in hand with the misleading idea that violence is abnormal and beyond comprehension. We would be far better off, Reemtsma argues, if we acknowledged the disturbing fact that violence is normal. (...) At the same time, Reemtsma contends that violence cannot be fully understood without delving into the concept of trust. Not in violence, but in trust, rests the foundation of true power. Reemtsma makes his case with a wide-ranging history of ideas about violence, from ancient philosophy through Shakespeare and Schiller to Michel Foucault, and by considering specific cases of extreme violence from medieval torture to the Holocaust and beyond. In the midst of this gloomy account of human tendencies, Reemtsma shrewdly observes that even dictators have to sleep at night and cannot rely on violence alone to ensure their safety. These authoritarian leaders must trust others while, by means other than violence, they must convince others to trust them. The history of violence is therefore a history of the peculiar relationship between violence and trust, and a recognition of trust's crucial place in humanity. A broad and insightful book that touches on philosophy, sociology, and political theory, Trust and Violence sheds new, and at times disquieting, light on two integral aspects of our society.

We generalize a well-known theorem binding the elementary equivalence relation on the level of PAC fields and the isomorphism type of their absolute Galois groups. Our results concern two cases: saturated PAC structures and nonsaturated PAC structures.

We extend stit logic by adding a spatial dimension. This enables us to distinguish between powers and opportunities of agents. Powers are agent-specific and do not depend on an agent’s location. Opportunities do depend on locations, and are the same for every agent. The central idea is to define the real possibility to see to the truth of a condition in space and time as the combination of the power and the opportunity to do so. The focus on agent-relative powers (...) and space-relative opportunities firmly roots effectivity of an autonomous choice making agent in a space–time picture. Our space–time view will be classically Newtonian, since we will assume relativistic phenomena do not play a role in agentive effectivity. We show how our semantics naturally distinguishes between different kinds of histories; histories that reflect real possibilities and histories that reflect counterfactual possibilities. Furthermore, we discuss how the spatial picture sheds light on conceptual problems plaguing the central stit property of ‘independence of agency’. At several points in the article we will emphasise and defend the differences with Belnap’s theory of agency in relativistic branching space–times. (shrink)

A common opinion is that power has shifted from states to companies. This article discusses quantitative and qualitative aspects of power possessed by companies and by states. A more adequate comparison than that between company sales and gross national product is the one between company value added and GNP. Also more adequate is the comparison between the public sector and company net profit. These rival measures take down company power to about a tenth of the sales measure. Also in qualitative (...) terms the "exit power" of the company gives a low impact compared to governmental action and the article concludes that company power by common measures is overestimated. However, the aggregated long-term effect of the market economy on the development of society is most significant. But it is a mistake to use that judgment as an argument for the opinion that business executives are the major power holders in modern societies. Perceptions of power also have an impact on which expectations and commitments that can be judged as realistic and therefore the issue of power is central for the normative discussion about corporate social responsibility.

La recherche récente a régulièrement remis en cause la catégorie moderne de « lois sacrées » désignant des inscriptions grecques qui forment un ensemble mal défini. Cet article entend dépasser le corpus traditionnel des « lois sacrées » en présentant un projet de recueil alternatif de « Normes rituelles grecques » (CGRN pour l’acronyme anglais), qui s’appuie sur des critères plus sélectifs et sera publié en ligne.

This article addresses the question whether Whiteheadians should be vegetarians in two ways. First, I question whether Whitehead should have been a vegetarian to be consistent, arguing that his omnivorous diet was inconsistent with his own philosophy. Second, I evaluate the works of three distinguished Whiteheadian philosophers on the ethics of vegetarianism. I argue that Charles Birch, John Cobb, and Jay McDaniel have prioritized animals justifiably over other organisms, yet that Birch and Cobb fail to do justice to the lives (...) of other animals, and that the account provided by McDaniel fails to provide a convincing argument for minimal moral vegetarianism.

In seiner Studie zeigt Jan Hoff, dass im Zuge der theoretischen Entdogmatisierung des Marxismus seit Mitte der 60er Jahre ebenso vielfältige wie fruchtbare Marx-Interpretationen und eine an der Marxschen Ökonomiekritik orientierte kritische Gesellschaftstheorie in zahlreichen Ländern der Welt ungeahnten Auftrieb erhielten. Insbesondere die wissenschaftliche Auseinandersetzung mit den verschiedenen Entwürfen zum "Kapital" hat sich in den letzten fünf Jahrzehnten beständig weiterentwickelt. In der Arbeit wird diese Globalisierung der Marx-Debatte, das komplexe Geflecht internationaler Theoriebezüge im Spannungsfeld von Wissenschaft und Politik, des Theorietransfers (...) und der Herausbildung von Denkschulen über nationale und sprachliche Grenzen hinweg untersucht. Sie bricht mit dem theoretischen Provinzialismus insbesondere der deutschen Marx-Diskussion, der sich bislang hartnäckig halten konnte. Der Autor gibt einen Überblick über die Marx-Rezeption in verschiedenen Weltregionen, wobei die außereuropäische Theoriebildung - etwa die facettenreiche Marx-Debatte in Japan - besondere Aufmerksamkeit erfährt. Der Marxismus im Sinne einer umfassenden Weltanschauung ist inzwischen historisch überwunden. Doch der Marxsche Theorienansatz, den inneren Zusammenhang der ökonomischen Kategorien und Verhältnisse zu explizieren und dabei mit einer kritischen Fetischismus- und Mystifikationstheorie eine "Entzauberung" der "verkehrten Welt" der Ökonomie zu leisten, ist nach wie vor von Aktualität und theoretischer Bedeutung.

Jan G. Michel argues that we need a philosophy of scientific discovery. Before turning to the question of what such a philosophy might look like, he addresses two questions: Don’t we have a philosophy of scientific discovery yet? And do we need one at all? To answer the first question, he takes a closer look at history and finds that we have not had a systematic philosophy of scientific discovery worthy of the name for over 150 years. To answer the (...) second question, Michel puts forward three arguments that show the importance of a philosophy of scientific discovery. Briefly, he arrives at the following answers: No, we don’t yet have a philosophy of scientific discovery, and yes, we definitely need one. To remedy this shortcoming, Michel analyzes the concept of discovery, leading him to the insight that scientific discoveries have an underlying structure with certain structural features. Some of these features may be important but not indispensable to scientific discovery processes; these include eureka moments, serendipities, joint discoveries, special science funding, and others. In addition, Michel identifies three indispensable structural features which he examines in detail and which he places in a picture with a certain dynamics according to which the process of making scientific discoveries can be seen as a path, leading us from finding and acceptance to knowledge.

A number of philosophers have found inspiration in the writings of Alfred Whitehead to develop their ideas on environmental and animal ethics. I explore the writings of Charles Hartshorne and Daniel Dombrowski to address the question of whether Whiteheadians should be vegetarians. I conclude that there is a morally relevant distinction between plants and animals, based on the Whiteheadian view that animals have higher grades of experience, and that this distinction grounds a moral duty to adopt minimal moral veganism.

The cosmological theory of the author, discussed in (Greben in Found Sci 15(2):153–176, 2010 ), has a number of implications for the interpretation of initial conditions and the fine-tuning problem as discussed by Vidal (Found Sci 15(4):375–393, 2010a ).

This paper examines the problem of genesis of logic in the light of naturalism as a philosophical view about the nature of knowledge and reality. The main difficulty of naturalism as far as applied to logic consists in reconciling genetic empiricism (all cognition starts with experience) and abstract nature of logic. Anti-naturalism (Platonism, for example) maintains than empiricism is not able to explain how logical theorems as a priori assertions are accumulated. To defend naturalism one should note that experiential character (...) of knowledge can be understood phylogenetically or ontogenetically. The former account is more suitable for naturalism and allows us to investigate genesis of logic by glasses of evolutionary theory. This way can be supplemented by an appeal to genetics. Both theories can explain how logical competence, that is ability to use deduction, arose in humans. The author claims that the structure of the genetic coded has some properties that became transformed into logical rule. Some analogies between consequence operation and topological closure are employed in analysis. (shrink)

This paper outlines the history of logic in Poland in the years 1918–1939 . The disciplinary and social history of logical investigations in Poland is widely described. The author stresses topics characteristic for Polish logic, namely prepositional calculus, many-valued logic, Lezśniewski's systems, Chwistek's systems and the works in the history of logic.

Color experience is structured. Some ?unique? colors (red, green, yellow, and blue) appear as ?pure,? or containing no trace of any other color. Others can be considered as a mixture of these colors, or as ?binary colors.? According to a widespread assumption, this unique/binary structure of color experience is to be explained in terms of neurophysiological structuring (e.g., by opponent processes) and has no genuine explanatory basis in the physical stimulus. The argument from structure builds on these assumptions to argue (...) that colors are not properties of surfaces and that color experiences are neural processes without environmental counterparts. We reconsider the argument both in terms of its logic and in the light of recent models in vision science which point at environment-involving patterns that may be at the basis of the unique/binary structure of color experience. We conclude that, in the light of internal and external problems which arise for it, the argument from structure fails. (shrink)

A serious difficulty for theories of consciousness is to go beyond mere correlation between physical processes and experience. Currently, neural workspace and sensorimotor contingency theories are two of the most promising approaches to make any headway here. This paper explores the relation between these two sets of theories. Workspace theories build on large-scale activity within the brain. Sensorimotor theories include external processes in their explanations, stressing the sensorimotor contingencies that arise from our interaction with the environment. Despite the basic differences, (...) we argue that workspace- and sensorimotor theories are complementary rather than competitive. By combining these theories, a number of problems that hamper them individually may be overcome and their strengths combined: Workspace theories have more to offer for explaining how there can be consciousness in the first place, while sensorimotor theories are strong in making sense of the specific phenomenal character of experiences.

The larger part of Yearbook 6 of the Institute Vienna Circle constitutes the proceedings of a symposium on Alfred Tarski and his influence on and interchanges with the Vienna Circle, especially those on and with Rudolf Carnap and Kurt Gödel. It is the first time that this topic has been treated on such a scale and in such depth. Attention is mainly paid to the origins, development and subsequent role of Tarski's definition of truth. Some contributions are primarily historical, others (...) analyze logical aspects of the concept of truth. Contributors include Anita and Saul Feferman, Jan Wolenski, Jan Tarski and Hans Sluga. Several Polish logicians contributed: Gzegorczyk, Wójcicki, Murawski and Rojszczak. The volume presents entirely new biographical material on Tarski, both from his Polish period and on his influential career in the United States: at Harvard, in Princeton, at Hunter, and at the University of California at Berkeley. The high point of the analysis involves Tarski's influence on Carnap's evolution from a narrow syntactical view of language, to the ontologically more sophisticated but more controversial semantical view. Another highlight involves the interchange between Tarski and Gödel on the connection between truth and proof and on the nature of metalanguages. The concluding part of Yearbook 6 includes documentation, book reviews and a summary of current activities of the Institute Vienna Circle. Jan Tarski introduces letters written by his father to Gödel; Paolo Parrini reports on the Vienna Circle's influence in Italy; several reviews cover recent books on logical empiricism, on Gödel, on cosmology, on holistic approaches in Germany, and on Mauthner.

Several areas of expanding corporate responsibilities are evident from current practices. This article penetrates one such field, economic compensation through litigation, and discusses the possibility and desirability of reversing the trend. In court, companies are fined increasing amounts for an ever wider range of faults, or they settle out of court under this legal threat. This is not a local American problem, but European companies are increasingly involved because of globalization. The development in Europe is also driven by the same (...) factors as in America – the mechanics of litigation and conventional ethics. The greed of plaintiffs and lawyers can mobilize the perceived virtue of sympathizing with a victim. Therefore it seems likely that a precondition for tort reform is an ethical reevaluation. Is it desirable and politically possible to make the individual more responsible for his own fate? (shrink)
