The Handbook of Modal Logic contains 20 articles, which collectively introduce contemporary modal logic, survey current research, and indicate the way in which the field is developing. The articles survey the field from a wide variety of perspectives: the underling theory is explored in depth, modern computational approaches are treated, and six major applications areas of modal logic (in Mathematics, Computer Science, Artificial Intelligence, Linguistics, Game Theory, and Philosophy) are surveyed. The book contains both well-written expository articles, suitable for beginners (...) approaching the subject for the first time, and advanced articles, which will help those already familiar with the field to deepen their expertise.

We model scientific theories as Bayesian networks. Nodes carry credences and function as abstract representations of propositions within the structure. Directed links carry conditional probabilities and represent connections between those propositions. Updating is Bayesian across the network as a whole. The impact of evidence at one point within a scientific theory can have a very different impact on the network than does evidence of the same strength at a different point. A Bayesian model allows us to envisage and analyze the (...) differential impact of evidence and credence change at different points within a single network and across different theoretical structures.

Our scientific theories, like our cognitive structures in general, consist of propositions linked by evidential, explanatory, probabilistic, and logical connections. Those theoretical webs ‘impinge on the world at their edges,’ subject to a continuing barrage of incoming evidence. Our credences in the various elements of those structures change in response to that continuing barrage of evidence, as do the perceived connections between them. Here we model scientific theories as Bayesian nets, with credences at nodes and conditional links between them modelled (...) as conditional probabilities. We update those networks, in terms of both credences at nodes and conditional probabilities at links, through a temporal barrage of random incoming evidence. Robust patterns of punctuated equilibrium, suggestive of ‘normal science’ alternating with ‘paradigm shifts,’ emerge prominently in that change dynamics. The suggestion is that at least some of the phenomena at the core of the Kuhnian tradition are predictable in the typical dynamics of scientific theory change captured as Bayesian nets under even a random evidence barrage.

The ability to recognise the actions of conspecifics from displays of biological motion is an essential perceptual capacity. Physiological and psychological evidence suggest that the visual processing of biological motion involves close interaction between the dorsal and ventral systems. Norman's strong emphasis on the functional differences between these systems may impede understanding of their interactions.

Although words like "fair" may have a common meaning, we cannot assume that people speak them or hear them in the same manner, or appreciate the impact of their implied interpretations and nuances. We describe three different perspectives -rational, emotional, and spiritual - which offer vastly different meanings of fairness. We also discuss the manner in which the different meanings they represent with respect to policies and practices are pursued by business interests within the American and international arenas.

The influence of stakeholders, organisational commitment, personal values, goals of the organisation and socio-demographic characteristics of individuals on the ethical dimension of behavioural intentions of employees in various organisations are investigated. The research results show that employees working for the public sector or in educational institutions take more ethical aspects into account than employees working in the "private" sector. The influence of stakeholders and organisational commitment do not significantly affect the ethical behaviour of employees, and only some personal values and (...) goals of the organisation have a significant influence on ethical behaviour. The most significant explanatory factor of ethical decision making seems to be what may be called "stage in the career of the employee": "ethical" employees can be described as young, with a relatively low income, limited work experience and a low level of responsibility in the company.

Probabilistic models of sentence comprehension are increasingly relevant to questions concerning human language processing. However, such models are often limited to syntactic factors. This restriction is unrealistic in light of experimental results suggesting interactions between syntax and other forms of linguistic information in human sentence processing. To address this limitation, this article introduces two sentence processing models that augment a syntactic component with information about discourse co-reference. The novel combination of probabilistic syntactic components with co-reference classifiers permits them to more (...) closely mimic human behavior than existing models. The first model uses a deep model of linguistics, based in part on probabilistic logic, allowing it to make qualitative predictions on experimental data; the second model uses shallow processing to make quantitative predictions on a broad-coverage reading-time corpus.

Extinct megafaunal mammals in the Americas are often linked to seed-dispersal mutualisms with large-fruiting tree species, but large-fruiting species in Europe and Asia have received far less attention. Several species of arboreal Maloideae (apples and pears) and Prunoideae (plums and peaches) evolved large fruits starting around nine million years ago, primarily in Eurasia. As evolutionary adaptations for seed dispersal by animals, the size, high sugar content, and bright colorful visual displays of ripeness suggest that mutualism with megafaunal mammals facilitated the (...) evolutionary change. There has been little discussion as to which animals were likely candidate(s) on the late Miocene landscape of Eurasia. We argue that several possible dispersers could have consumed the large fruits, with endozoochoric dispersal usually relying on guilds of species. During the Pleistocene and Holocene, the dispersal guild likely included ursids, equids, and elephantids. During the late Miocene, large primates were likely also among the members of this guild, and the potential of a long-held mutualism between the ape and apple clades merits further discussion. If primates were a driving factor in the evolution of this large-fruit seed-dispersal system, it would represent an example of seed-dispersal-based mutualism with hominids millions of years prior to crop domestication or the development of cultural practices, such as farming.

The paper reports the findings of a study of CPAs designed to determine whether they tend to find factors related to their professional environment (especially the guides to professional conduct of the American Institute of Certified Public Accountants) to be more helpful than factors related to their business environment when faced with ethics problems. Like internal auditors surveyed earlier, the CPAs tend to view a number of factors in their business environment to be even more helpful than factors related to (...) their professional environment in dealing with ethical dilemmas. Implications for CPAs as individuals and for their professional associations are discussed. (shrink)

An historical overview of the United Nations sustainable development initiative reflects a convergence of political and ethical concerns, and a need to incorporate business and the ethics of business into an inclusive perspective. Underlying all of the resolutions and recommendations ensuing from that initiative is the age-old question of “the one and the many,” with which theology and philosophy have grappled for centuries, and sociology and politics in more recent times. Inherent to sustainable development is a need to overcome that (...) question, especially with respect to the power of the wealthier nations. Good old American Pragmatism offers a solution which, at once, respects individual and communal sovereignty while positing a dynamic interaction between the two. That interaction offers an optimistic approach to global business and to global business ethics. (shrink)

This paper contains a short outline of the rationale behind a workshop aimed at seeking connections between corporate social responsibility and corporate political activity. Two ‘provocateurs’ gave their view on these connections. After this kick-off two groups of ~10 persons each engaged in lively discussions on these connections, identifying a range of issues for further research and an interest in keeping this issue on the agenda.

Sickle cell haemoglobin polymerization reduces erythrocyte deformability, causing deleterous vaso-occlusions. The double-nucleation model states that polymers grow from HbS aggregates, the nuclei, in solution , onto existing polymers . When linearized at initial HbS concentration, this model predicts early polymerization and its characteristic delay-time :591–610, 611–631, 1985). Addressing its relevance for describing complete polymerization, we constructed the full, non-linearized model . Here, we compare the simulated outputs to experimental progress curves . Within 10% from start, average root mean square deviation (...) between simulated and experimental curves is 0.04 ± 0.01 . Conversely, for complete progress curves, averaged rms is 0.48 ± 0.04. This figure is improved to 0.13 ± 0.01 by adjusting heterogeneous pathway parameters : the nucleus stability , and the fraction of polymer surface available for nucleation , from 5e−7, to 13 . Similar results are obtained at 37°C. We conclude that the physico-chemical description of heterogeneous nucleation warrants refinements in order to capture the whole HbS polymerization process.

Fibroblast growth factor receptors (FGFRs) have been implicated in many developmental and regenerative events, including axial organisation, mesodermal patterning, keratinocyte organisation and brain development. The consensus view that this reflects a role for one or other of the nine known members of the fibroblast growth factor family in these processes has recently been challenged by the suggestion that FGFRs might be directly activated by a much wider range of ligands, including heparan sulphate proteoglycans and neural cell adhesion molecules. In addition, (...) two novel soluble ligands for FGFRs have been identified using yeast two‐hybrid technology. Overall, the new findings suggest that in terms of ligand binding the FGFRs might be an even more promiscuous family of receptor tyrosine kinases than was already appreciated. (shrink)

Each annual Ontology Summit initiative makes a statement appropriate to each Summit’s theme as part of our general advocacy designed to bring ontology science and engineering into the mainstream. The theme this year is "Towards an Open Ontology Repository". This communiqué represents the joint position of those who were engaged in the year's summit discourse on an Open Ontology Repository (OOR) and of those who endorse below. In this discussion, we have agreed that an "ontology repository is a facility where (...) ontologies and related information artifacts can be stored, retrieved and managed." -/- We believe in the promise of semantic technologies based on logic, databases and the Semantic Web, a Web of exposed data and of interpretations of that data (i.e., of semantics), using common standards. Such technologies enable distinguishable, computable, reusable, and sharable meaning of Web and other artifacts, including data, documents, and services. We also believe that making that vision a reality requires additional supporting resources and these resources should be open, extensible, and provide common services over the ontologies. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Case against Rational Egoism in Dostoevsky’s Notes from Underground*James P. ScanlanWriting in his own voice, in letters, notebooks, and diaries, Fyodor Dostoevsky frequently attacked the philosophy of the Russian “nihilists,” as he typically called them—Nikolay Chernyshevsky, Dmitry Pisarev, and other representatives of the radical Russian intelligentsia in the third quarter of the nineteenth century. But because Dostoevsky also used fiction to argue against them, if we wish to (...) discern the full contours of his opposition, we must turn to his stories and novels; and there we face the problem of determining to what extent, if any, the statements of his narrators and characters express his own views.This problem is particularly challenging in regard to the radicals’ “Rational Egoism,” to use the label by which the Russian variant of the theory of enlightened egoism came to be known. 1 Dostoevsky’s most sustained and spirited attack on that aspect of “nihilist” philosophy is found in Part One of Notes from Underground (1864), but it is voiced by one of the darkest, least sympathetic of all his characters—the nameless narrator and protagonist known as the Underground Man. Was this repellent creature speaking for Dostoevsky? The Underground Man, moreover, can easily be viewed as a sheer irrationalist whose rejection of Rational Egoism is a tortured emotional outburst with no logical credentials. Robert L. Jackson, in his groundbreaking study of 1958, describes the Underground Man’s thinking at one point as follows: “It is impossible to argue [End Page 549] with the rationalists: reason is on their side. All that remains is irrationally to negate reason.” 2 If those words were to be taken not simply as a moment in Jackson’s rich analysis but as a comprehensive description of the Underground Man’s attitude, it would be senseless to expect philosophically nuanced arguments from him. And we would have no grounds for thinking that Dostoevsky’s own treatment of Rational Egoism went beyond emotional rejection.Critics from Vasily Rozanov to Joseph Frank have debated the Underground Man’s stance toward Rational Egoism and its relation to Dostoevsky’s, with no sign yet of a definitive resolution. Frank’s recent treatment, presented in the third volume of his monumental literary biography of Dostoevsky, offers a helpful history of the dispute as well as his own finely elaborated interpretation of the Underground Man as an irrational opponent of Rational Egoism. 3 Frank reads Notes from Underground as satire, and he contends that the Underground Man is caught in an agonizing self-contradiction: intellectually, he accepts the basic premises of the Rational Egoists’ outlook, such as the denial of free will; but he finds that, “despite the convictions of his reason,” he cannot live with the amoral and dehumanizing implications of those premises, which strip human beings of moral responsibility. 4 From a rational point of view, of course, rejection of the implications should force the Underground Man to reject the premises as well (by the hoary logical law of modus tollendo tolens), and indeed he does at times passionately condemn them. But according to Frank, these condemnations simply show the depth of his predicament: his “intellectual acceptance” of Chernyshevsky’s determinism is conjoined with “simultaneous rejection of it with the entire intuitive-emotional level of personality identified with moral conscience,” causing him to respond irrationally in a multitude of instances. 5 Frank’s Underground Man, then, is an intellectual disciple but an emotional critic of Rational Egoism; and he is triply an irrationalist: his thinking is mired in self-contradiction, he acts irrationally as a result, and his opposition to Rational Egoism has not a rational but an “intuitive-emotional” basis.But where does this leave Dostoevsky? Must we conclude that he, too, is somehow suspended between acceptance and rejection of Rational Egoism and for that reason has created in Notes from Underground a Bakhtinian equilibrium in which neither position is clearly privileged? For Frank, certainly not. It follows from Frank’s analysis that Dostoevsky himself, unlike the Underground [End Page 550] Man, is a fully consistent opponent of Rational Egoism, for that theory is the target of the inverted irony at the core of his satire; “the...

This is a long critical discussion of Frank Wilderson's Afropessimism, focusing primarily on Wilderson's claim that Blackness is equivalent to Slaveness. The article draws out some strengths of the book, but argues that the book's central arguments often rest on shaky methodological, metaphysical, epistemic, and political grounds. Along the way, we consider some complications endemic to the project of evaluating a text so clearly geared towards Black audiences from the perspective of a non-Black reader.

This book presents the origins of Central and Eastern European phenomenology. It features chapters that explore the movement's development, its most important thinkers, and its theoretical and historical context. This collection examines such topics as the realism-idealism controversy, the status of descriptive psychology, the question of the phenomenological method, and the problem of the world. The chapters span the first decades of the development of phenomenology in Czechoslovakia, Poland, Romania, Russia, and Yugoslavia before World War II. The contributors track the (...) Brentanian heritage of the development. They show how this tradition inspired influential thinkers like Celms, Špet, Ingarden, Frank, Twardowski, Patočka, and others. The book also puts forward original investigations. Moreover it elaborates new accounts of the foundations of phenomenology. While the volume begins with the Brentanian heritage, it situates phenomenology in a dialogue with other important schools of thought of that time, including the Prague School and Lvov-Warsaw School of Logic. This collection highlights thinkers whose writings have had only a limited reception outside their home countries due to political and historical circumstances. It will help readers gain a better understanding of how the phenomenological movement developed beyond its start in Germany. Readers will also come to see how the phenomenological method resonated in different countries and led to new philosophical developments in ontology, epistemology, psychology, philosophy of culture, and philosophy of religion.

The Institute Vienna Circle held a conference in Vienna in 2003, Cambridge and Vienna – Frank P. Ramsey and the Vienna Circle, to commemorate the philosophical and scientific work of Frank Plumpton Ramsey (1903–1930). This Ramsey conference provided not only historical and biographical perspectives on one of the most gifted thinkers of the Twentieth Century, but also new impulses for further research on at least some of the topics pioneered by Ramsey, whose interest and potential are greater than ever. Ramsey (...) did pioneering work in several fields, practitioners of which rarely know of his important work in other fields: philosophy of logic and theory of language, foundations of mathematics, mathematics, probability theory, methodology of science, philosophy of psychology, and economics. There was a focus on the one topic which was of strongest mutual concern to Ramsey and the Vienna Circle, namely the question of foundations of mathematics, in particular the status of logicism. Although the major scientific connection linking Ramsey with Austria is his work on logic, to which the Vienna Circle dedicated several meetings, certainly the connection which is of greater general interest concerns Ramsey's visits and discussions with Wittgenstein. Ramsey was the only important thinker to actually visit Wittgenstein during his school-teaching career in Puchberg and Ottertal in the 1920s, in Lower Austria; and later, Ramsey was instrumental in getting Wittgenstein positions at Cambridge.

Does the universe embody beautiful ideas? Artists as well as scientists throughout human history have pondered this "beautiful question." With Nobel laureate Frank Wilczek as your guide, embark on a voyage of related discoveries, from Plato and Pythagoras up to the present. Wilczek's groundbreaking work in quantum physics was inspired by his intuition to look for a deeper order of beauty in nature. In fact, every major advance in his career came from this intuition: to assume that the universe embodies (...) beautiful forms, forms whose hallmarks are symmetry--harmony, balance, proportion--and economy. There are other meanings of "beauty," but this is the deep logic of the universe--and it is no accident that it is also at the heart of what we find aesthetically pleasing and inspiring. As he reveals here, this has been the heart of scientific pursuit from Pythagoras, the ancient Greek who was the first to argue that "all things are number," to Galileo, Newton, Maxwell, Einstein, and into the deep waters of twentieth-century physics. Gorgeously illustrated, A Beautiful Question is a mind-shifting book that braids the age-old quest for beauty and the age-old quest for truth into a thrilling synthesis. Yes: the world is a work of art, and its deepest truths are ones we already feel, as if they were somehow written in our souls.--From publisher description. (shrink)

One of our great contemporary scientists presents ten insights that illuminate what every thinking person needs to know about what the world is and how it works. Nobel Prize winner Frank Wilczek's Fundamentals is built around a simple but profound idea: the models of the world we construct as children are practical and adequate for everyday life, but they do not bring in the surprising and mind-expanding revelations of modern science. To do that, we must look at the world anew, (...) combining clear thinking with an openness to wonder. This "born again" world is in many ways larger, fuller, and much stranger than it appears. Through an exploration of space, time, matter, and ideas--and equipped with facts, questions, and brilliant speculations--Wilczek guides us through the past, present, and future of fundamental science. Readers will emerge with an expanded vision of our universe. Author Bio: Frank Wilczek won the Nobel Prize in Physics in 2004 for work he did as a graduate student. He was among the earliest MacArthur fellows, and has won many awards both for his scientific work and his writing. He is the author of A Beautiful Question, The Lightness of Being, Fantastic Realities, Longing for the Harmonies, and hundreds of articles in leading scientific journals. His "Wilczek's Universe" column appears regularly in the Wall Street Journal. Wilczek is the Herman Feshbach Professor of Physics at the Massachusetts Institute of Technology, founding director of the T. D. Lee Institute and chief scientist at the Wilczek Quantum Center in Shanghai, China, and a distinguished professor at Arizona State University and Stockholm University. (shrink)

Der Übergang vom Verhältnisbewußtsein zum Selbstbewußtsein kann unmöglich nur vom Verhältnisbewußtsein aus gedacht werden, weil wir uns eine Welt, in der das Bewubtsein unserer selbst verteilt ist auf die Dimensionen der Handlung vor deren Zentrierung in uns, gar nicht vorstellen können. Jedes Tableau der Handlungsmöglichkeiten, so abstrakt es auch abgefaßt sein mag, ist gebunden an Vorstellungen möglicher Handlungssubjekte, denen wir Handlungsmöglichkeiten zuschreiben. Handlungstheorie ist daher notwendig Reflexion unserer Praxis, in der wir uns selbst als Selbstbewußtsein erfahren, das seinem Verhältnisbewubtsein enthoben (...) ist, ohne dieses dadurch selbst schon aufzuheben zu können. Daß uns Freiheit im Handeln unaufhebbar prekär und problematisch bleiben mub, ist die Grundvoraussetzung dafür, dab wir Handlungstheorien historisch und bereichsbezogen ständig neu entwerfen müssen. Das Verhältnis von Handlungsphilosophie zu Handlungstheorien kann daher so gefaßt werden, daß Handlungsphilosophie die Grundbegrifflichkeit in kritischer Absicht bereitstellt, die den bereichsorientierten, mehr oder weniger deskriptiven Handlungstheorien abgehen muß. Dazu muß die ontologische Differenz von Handlung und Interpretation methodologisch ernst genommen werden. Die radikale Andersheit der hier zu begründenden Konzeption liegt vor allem in der Ansicht, daß Handlungen nicht als isolierbare Ereignis-Entitäten aufgefaßt werden können, die gegenüber der »Welt der Tatsachen des Bewußtseins« eine kausale, d.h. von der Welt des Bewußtseins abgetrennte Rolle übernehmen.

Although declarations of the death of God seem to be provocations announcing the end of the era of theology, this announcement is actually central to the Christian revelation in its most classic forms, as well as to its reworkings in contemporary religious thought. Indeed provocative new possibilities for thinking theologically open up precisely in the wake of the death of God. Already Hegel envisaged a revolutionary new realization of divinity emerging in and with the secular world through its establishment of (...) a total order of immanence. However, in postmodern times this comprehensive order aspired to by modern secularism implodes or cracks open towards the wholly Other. A hitherto repressed demand for the absolute difference of the religious, or for “transcendence”, returns with a vengeance. This difference is what could not be stated in terms of the Hegelian System, for reasons that poststructuralist writers particularly have insisted on: all representations of God are indeed dead. Yet this does not mean that they cannot still be powerful, but only that they cannot assign God any stable identity. Nietzsche’s sense of foreboding concerning the death of God is coupled with his intimations of the demise of representation and “grammar” as epistemologically bankrupt, but also with his vision of a positive potential for creating value in the wake of this collapse of all linguistically articulated culture. He points the way towards the emergence of a post-secular religious thinking of what exceeds thought and representation. (shrink)

Why do humans make music? Theories of the evolution of musicality have focused mainly on the value of music for specific adaptive contexts such as mate selection, parental care, coalition signaling, and group cohesion. Synthesizing and extending previous proposals, we argue that social bonding is an overarching function that unifies all of these theories, and that musicality enabled social bonding at larger scales than grooming and other bonding mechanisms available in ancestral primate societies. We combine cross-disciplinary evidence from archeology, anthropology, (...) biology, musicology, psychology, and neuroscience into a unified framework that accounts for the biological and cultural evolution of music. We argue that the evolution of musicality involves gene–culture coevolution, through which proto-musical behaviors that initially arose and spread as cultural inventions had feedback effects on biological evolution because of their impact on social bonding. We emphasize the deep links between production, perception, prediction, and social reward arising from repetition, synchronization, and harmonization of rhythms and pitches, and summarize empirical evidence for these links at the levels of brain networks, physiological mechanisms, and behaviors across cultures and across species. Finally, we address potential criticisms and make testable predictions for future research, including neurobiological bases of musicality and relationships between human music, language, animal song, and other domains. The music and social bonding hypothesis provides the most comprehensive theory to date of the biological and cultural evolution of music. (shrink)
