It is shown that the expressive power of second-order propositional modal logic whose modalities are S4.2 or weaker is the same as that of second-order predicate logic.

ABSTRACTLawyers play an important role in protecting the interests of the vulnerable in society. Increasingly those engaged in working with clients who are mentally ill, elderly, or experiencing fluctuating mental capacity, are called upon to make decisions and protect interests of clients who struggle to understand the legal consequence and meaning of their decisions. Ethical principles that prohibit lawyers acting on anything other than competent instructions, and disapprove of acting ‘in the best interests’ of clients in the absence of competent (...) instructions, create a series of philosophical and practical challenges to lawyers who work in this area. This article considers the evolution of ethical guidelines in Australia and the United States, noting the significant divergence in philosophy and practice within these jurisdictions. (shrink)

Humanity and the very notion of the human subject are under threat from postmodernist thinking which has declared not only the 'Death of God' but also the 'Death of Man'. This book is a revindication of the concept of humanity, rejecting contemporary social theory that seeks to diminish human properties and powers. Archer argues that being human depends on an interaction with the real world in which practice takes primacy over language in the emergence of human self-consciousness, thought, emotionality and (...) personal identity - all of which are prior to, and more basic than, our acquisition of a social identity. This original and provocative new book from leading social theorist Margaret S. Archer builds on the themes explored in her previous books Culture and Agency (CUP 1988) and Realist Social Theory (CUP 1995). It will be required reading for academics and students of social theory, cultural theory, political theory, philosophy and theology. (shrink)

In recent years, the free market position has been gaining strength. In this book, Radin provides a nuanced response to its sweeping generalization.

The central problem of social theory is 'structure and agency'. How do the objective features of society influence human agents? Determinism is not the answer, nor is conditioning as currently conceptualised. It accentuates the way structure and culture shape the social context in which individuals operate, but it neglects our personal capacity to define what we care about most and to establish a modus vivendi expressive of our concerns. Through inner dialogue, 'the internal conversation', individuals reflect upon their social situation (...) in the light of current concerns and projects. On the basis of a series of unique, in-depth interviews, Archer identifies three distinctive forms of internal conversation. These govern agents' responses to social conditioning, their individual patterns of social mobility and whether or not they contribute to social stability or change. Thus the internal conversation is seen as being the missing link between society and the individual, structure and agency. (shrink)

This book presents the proceedings of the 2nd Karl Schwarzschild Meeting on Gravitational Physics, focused on the general theme of black holes, gravity and information. Specialists in the field of black hole physics and rising young researchers present the latest findings on the broad topic of black holes, gravity, and information, highlighting its applications to astrophysics, cosmology, particle physics, and strongly correlated systems.

Persons infected with the Human Immunodeficiency Virus often experience intermittent life-threatening infections, a progressive decrease in cognitive abilities, and a loss of capacity to communicate their wishes to their family and medical care providers. Accordingly, AIDS patients are among those most likely to benefit from the increased availability of legally recognized forms of advance care planning. Although the three countries examined in this article differ greatly in the prevalence of HIV infection, the legal status of advance directives, and in the (...) attitudes toward their use, a collection of case studies is used to demonstrate that an ability to address the specific needs, values and goals of individual patients is promoted by the availability of a variety of options for implementing advance directives or health care proxies. The conclusion of the analysis is that the best option in a specific context will depend upon differences in individual values and medical objectives of the sort discussed in the case studies. Das mit der HIV-Infektion verbundene Krankheitsbild ist durch wechselnde lebensbedrohliche Infektionen und den fortschreitenden Verfall kognitiver Fähigkeiten gekennzeichnet. Es führt zudem häufig zum Verlust der Möglichkeit, Behandlungswünsche gegenüber Ärzten und Angehörigen zu äußern. Deshalb gehören besonders AIDS-Patienten zu denjenigen, die von rechtlich anerkannten vorsorglichen Patientenverfügungen profitieren werden.In diesem Artikel werden drei Länder betrachtet, die sich hinsichtlich der Häufigkeit des Auftretens der HIV-Infektion sowie des rechtlichen Status von und der Einstellung zu Patientenverfügungen erheblich unterscheiden. Fallstudien belegen allerdings, daß nicht allein die kulturellen und sozialen Bedingungen für die jeweils beste Form der Patientenverfügung ausschlaggebend sind. Voraussetzung für die Möglichkeit, den Bedingungen, Wert- und Zielvorstellungen des individuellen Patienten zu entsprechen, ist auf jeden Fall die Verfügbarkeit unterschiedlicher Formen von Patienten- und Betreuungsverfügungen. Auch innerhalb eines Kulturkreises müssen daher verschiedene Formen vorsorglicher Willensäußerungen des Patienten rechtlich anerkannt werden. Welche Art von Verfügung jeweils die beste Option darstellt, ist dabei abhängig von medizinischen Bedingungen und persönlichen Wertvorstellungen, wie sie in den Fallstudien diskutiert werden.

We motivate and formalize the idea of sameness by default: two objects are considered the same if they cannot be proved to be different. This idea turns out to be useful for a number of widely different applications, including natural language processing, reasoning with incomplete information, and even philosophical paradoxes. We consider two formalizations of this notion, both of which are based on Reiter’s Default Logic. The first formalization is a new relation of indistinguishability that is introduced by default. We (...) prove that the corresponding default theory has a unique extension, in which every two objects are indistinguishable if and only if their non-equality cannot be proved from the known facts. We show that the indistinguishability relation has some desirable properties: it is reflexive, symmetric, and, while not transitive, it has a transitive “flavor.” The second formalization is an extension (modification) of the ordinary language equality by a similar default: two objects are equal if and only if their non-equality cannot be proved from the known facts. It appears to be less elegant from a formal point of view. In particular, it gives rise to multiple extensions. However, this extended equality is better suited for most of the applications discussed in this paper. (shrink)

Since the publication of Roy Bhaskar's A Realist Theory of Science in 1975, critical realism has emerged as one of the most powerful new directions in the philosophy of science and social science, offering a real alternative to both positivism and postmodernism. This reader makes accessible in one volume key readings to stimulate debate about and within critical realism, including: the transcendental realist philosophy of science elaborated in A Realist Theory of Science ; Bhaskar's critical naturalist philosophy of social science; (...) the theory of explanatory critique, which is central to critical realism; and the theme of dialectic, which is central to Bhaskar's most recent writings. The volume includes extracts from Bhaskar's most important books, as well as selections from all of the other most important contributors to the critical realist program. It also includes both a general introduction and original introductions to each section. (shrink)

What is a crip politics of bodymind? Drawing upon Rosemarie Garland-Thomson's theory of the misfit, I explain my understanding of crip and bodymind within a feminist materialist framework, and argue that careful investigation of a crip politics of bodymind must involve accounting for two key, but under-explored, disability studies concepts: desire and pain. I trace the turn toward desire that has characterized DS theory for the last decade, and argue that while acknowledging disability desire, we must also attend to the (...) aspects of disability, including pain, that are sometimes bad. Although I don't argue that pain is always and only bad, I call for recognition of the ways pain complicates disability desire, as well as the possibilities it opens for specifically located, collective forms of care.

Infants can see someone pointing to one of two buckets and infer that the toy they are seeking is hidden inside. Great apes do not succeed in this task, but, surprisingly, domestic dogs do. However, whether children and dogs understand these communicative acts in the same way is not yet known. To test this possibility, an experimenter did not point, look, or extend any part of her body towards either bucket, but instead lifted and shook one via a centrally pulled (...) rope. She did this either intentionally or accidentally, and did or did not address her act to the subject using ostensive cues. Young 2-year-old children but not dogs understood the experimenter’s act in intentional conditions. While ostensive pulling of the rope made no difference to children’s success, it actually hindered dogs’ performance. We conclude that while human children may be capable of inferring communicative intent from a wide variety actions, so long as these actions are performed intentionally, dogs are likely to be less flexible in this respect. Their understanding of communicative intention may be more dependent upon bodily markers of communicative intent, including gaze, orientation, extended limbs, and vocalisations. This may be because humans have come under selective pressure to develop skills for communicating with absent interlocutors – where bodily co-presence is not possible. (shrink)

The underdetermination of scientific theory choice by evidence is a familiar but multifaceted concept in the philosophy of science. I answer two pressing questions about underdetermination: “What is underdetermination?” and “Why should we care about underdetermination?” To answer the first question, I provide a general definition of underdetermination, identify four forms of underdetermination, and discuss major criticisms of each form. To answer the second question, I then survey two common uses of underdetermination in broader arguments against scientific realism and in (...) support of the use of values in scientific theory choice. I conclude that philosophers should also care about underdetermination because it impacts scientists in their practice. (shrink)

Religious beliefs, it has been noted, are often hard to disprove. While this would be a shortcoming for beliefs whose utility was connected to their accuracy, it is actually necessary in the case of beliefs whose function bears no connection to how accurate they are. In the case of religions and other ideologies that serve to promote prosocial behaviour this leads to the need to protect belief systems against potentially disruptive counterevidence while maintaining their relevance. Religions turn out to be (...) particularly adept at this because of the use they make of existing cognitive by-products to make them plausible without exposingthem overly to investigation. (shrink)

"Konrad Talmont-Kaminski offers a very thoughtful and thought-provoking critique of the field and an alternative approach to magic, religion, and science that should spark some debate and further research Talmont-Kaminski has thrown down a challenge to the mainstream of anthropological thought about religion, and it is a challenge that we necessarily and gladly pick up." -- Anthropology Review Database "A philosophical naturalist's delight, this book - crisply written and carefully argued - weaves together insights about evolution, mind, and (...) society to explain how religions work and how secularisation threatens them." - Robert N. McCauley, Emory University Is religious belief a product of the mind? This book brings to light the multifaceted relationship between reason and religion. Religion as Magical Ideology examines the relationship between rationality and supernatural beliefs arguing that such beliefs are products of evolution, cognition and culture. The book does not offer a false rapprochement between reason and religion; instead, it explores their interrelationship as a series of complex adaptations between cognitive and cultural processes. Exploring the nature of the tension between religious traditions and reason, Religion as Magical Ideology develops a dual inheritance theory of religion - which combines the cognitive byproduct and prosocial adaptation accounts - and analyses the connection between the function of a belief and the degree of protection it gets from potential counter-evidence. With discussion ranging from individual cognitive mechanisms, general functional considerations, to the limits of evolutionary and cognitive processes, the book offers readers a systematic account of how cognition shapes religious beliefs and practices.

Atheism as a belief does not have to present intellectual credentials within academia. Yet to hold beliefs means giving reasons for doing so, ones which may be found wanting. Instead, atheism is the automatic default setting within the academic world. Conversely, religious belief confronts a double standard. Religious believers are not permitted to make truth claims but are instead forced to present their beliefs as part of one language game amongst many. Religious truth claims are expected to satisfy empiricist criteria (...) of evidence but when they fail, as they must, religious belief becomes subject to the hermeneutics of suspicion. This book explores religious experience as a justifiable reason for religious belief. It uniquely demonstrates that the three pillars of critical realism --ontological intransitivity, epistemic relativity and judgemental rationality -- can be applied to religion as to any other beliefs or theories. The three authors are critical realists by philosophical position. They seek to establish a level playing field between religion and secular ideas, which has not existed in the academic world for some generations, in order for reasoned debate to be conducted.

Both science and religion are human endeavours that recruit and modify pre-existing human capacity to engage in epistemic vigilance. However, while science relies upon a focus on content vigilance, religion focusses on source vigilance. This difference is due, in turn, to the function of religious claims not being connected to their accuracy – unlike the function of scientific claims. Understanding this difference helps to understand many aspects of scientific and religious institutions.

The paper presents a generalization of pregroup, by which a freely-generated pregroup is augmented with a finite set of commuting inequations, allowing limited commutativity and cancelability. It is shown that grammars based on the commutation-augmented pregroups generate mildly context-sensitive languages. A version of Lambek’s switching lemma is established for these pregroups. Polynomial parsability and semilinearity are shown for languages generated by these grammars.

This collection of essays by one of the country's leading property theorists revitalizes the liberal personality theory of property. Departing from traditional libertarian and economic theories of property, Margaret Jane Radin argues that the law should take into account nonmonetary personal value attached to property—and that some things, such as bodily integrity, are so personal they should not be considered property at all. Gathered here are pieces ranging from Radin's classic early essay on property and personhood to her recent (...) works on governmental "taking" of private property. Margaret Jane Radin is professor of law at Stanford University. She is the author of over twenty-five articles on legal and political theory. (shrink)

This paper argues for a methodological point that bears on a relatively long-standing debate concerning collective beliefs in the sense elaborated by Margaret Gilbert: are they cases of belief or rather of acceptance? It is argued that epistemological accounts and distinctions developed in individual epistemology on the basis of considering the individual case are not necessarily applicable to the collective case or, more generally, uncritically to be adopted in collective epistemology.

Scientificity is essentially methodology. The use of information technology as methodological instruments in science has been increasing for decades, this raises the question: Does this transform science? This question is the subject of the Special Issue in Minds and Machines “The epistemological significance of methods in computer simulation and machine learning”. We show that there is a technological change in this area that has three methodological and epistemic consequences: methodological opacity, reproducibility issues, and altered forms of justification.
