Associated with each first-order theory is a Boolean algebra of sentences and a Boolean space of models. Homomorphisms between the sentence algebras correspond to continuous maps between the model spaces. To what do recursive homomorphisms correspond? We introduce axiomatizable maps as the appropriate dual. For these maps we prove a Cantor-Bernstein theorem. Duality and the Cantor-Bernstein theorem are used to show that the Boolean sentence algebras of any two undecidable languages or of any two functional languages are recursively isomorphic where (...) a language is undecidable iff it has at least one operation or relation symbol of two or more places or at least two unary operation symbols, and a language is functional iff it has exactly one unary operation symbol and all other symbols are for unary relations, constants, or propositions.

Individualism: The Cultural Logic of Modernity is an edited collection of sixteen essays on the idea of the modern sovereign individual in the western cultural tradition. Reconsidering the eighteenth-century realist novel, twentieth-century modernism, and underappreciated topics on individualism and literature, this volume provocatively revises and enriches our understanding of individualism as the generative premise of modernity itself.

This chapter argues that epistemic uses of the imagination are a sui generis form of reasoning. The argument proceeds in two steps. First, there are imaginings which instantiate the epistemic structure of reasoning. Second, reasoning with imagination is not reducible to reasoning with doxastic states. Thus, the epistemic role of the imagination is that it is a distinctive way of reasoning out what follows from our prior evidence. This view has a number of important implications for the epistemology of the (...) imagination. For one thing, it clarifies the epistemic role of widely invoked “constraints” on the imagination. For another, it highlights important and underappreciated disanalogies between how perceptual experiences and imaginings justify beliefs. Ultimately, the view that we can reason with imagination offers an illuminating and theoretically fruitful framework through which to understand the epistemic structure of the imagination. (shrink)

How do communities establish shared communication systems? The Common Knowledge view assumes that symbolic conventions develop through the accumulation of common knowledge regarding communication practices among the members of a community. In contrast with this view, it is proposed that coordinated communication emerges a by‐product of local interactions among dyads. A set of multi‐agent computer simulations show that a population of “egocentric” agents can establish and maintain symbolic conventions without common knowledge. In the simulations, convergence to a single conventional system (...) was most likely and most efficient when agents updated their behavior on the basis of local rather than global, system‐level information. The massive feedback and parallelism present in the simulations gave rise to phenomena that are often assumed to result from complex strategic processing on the part of individual agents. The implications of these findings for the development of theories of language use are discussed. (shrink)

This paper develops a theory of analog representation. We first argue that the mark of the analog is to be found in the nature of a representational system’s interpretation function, rather than in its vehicles or contents alone. We then develop the rulebound structure theory of analog representation, according to which analog systems are those that use interpretive rules to map syntactic structural features onto semantic structural features. The theory involves three degree-theoretic measures that capture three independent ways in which (...) a system can be more or less analog. We explain how our theory improves upon prior accounts of analog representation, provides plausible diagnoses for novel challenge cases, extends to hybrid systems that are partially analog and partially symbolic, and accounts for some of the advantages and disadvantages of representing analogically versus symbolically.

The author attempted to present the development of legal theories through early & medieval philosophical history.

In his prose writings, Milton produces a reinvention of the concept of heresy, and subsequently a theological reinvention of the nature of English society. He envisions a Protestant society united by practices of individual piety and by the “heretical imperative” of autonomous choice. While Milton’s account seeks to eliminate the possibilities of religious violence and state persecution, it leads finally to the same impasse as the Lockean theory: the grounding of a right to toleration on subjective piety necessarily excludes those (...) groups who refuse to practice such piety. Nevertheless, Milton’s unique depiction of a society united by practices of heresy ultimately points toward modernity in a way that is even more remarkably prescient than Locke’s influential theory of toleration.

The Printed Reader explores the transformative power of reading in the eighteenth century, and how this was expressed in the fascination with Don Quixote and in a proliferation of narratives about quixotic readers, readers who attempt to reproduce and embody their readings. The collection brings together key debates concerning quixotic narratives, print culture, sensibility, empiricism, book history, and the material text, connecting developments in print technology to gendered conceptualizations of quixotism.

ABSTRACT The primary aim of the paper is to apply the concept of retribution to nuclear defence policy. Nuclear defence policy, as I conceive it, is concerned with addressing the threat Soviet nuclear weapons pose for Western security. I argue that, contrary to popular opinion, MAD is not a retributive doctrine—that in fact it violates two constitutive principles of retribution: culpability and proportionality. After explicating these constitutive principles, I apply them to retaliatory strategy—showing that the culpability criterion restricts retaliation to (...) the agents of aggression while the proportionality criterion requires a just measure of retaliation. The result is a defence policy continuous with the just war tradition—one which rules out deterrence based on threats against the civilian population. I show why a retributive policy requires non‐nuclear forces and discuss the feasiblity of replacing all nuclear forces with conventional weapons. I anticipate and answer major objections to the denuclearization of U.S. and NATO forces. Finally, I conclude that an advocate of a retributive policy—specifically, a policy calling for a proportional or measured response against combatants only—must be willing, in the name of justice, to accept the risk of making war more thinkable by making it less horrible.

Background Despite the growth of biomedical research in South Africa, there are few insights into the operation of Research Ethics Committees (RECs) in this setting. We investigated the composition, operations and training needs of health RECs in South Africa against the backdrop of national and international guidelines. Methods The 12 major health RECs in South Africa were surveyed using semi-structured questionnaires that investigated the composition and functions of each REC as well as the operational issues facing committees. Results Health RECs (...) in SA have an average of 16 members and REC members are predominantly male and white. Overall, there was a large discrepancy in findings between under-resourced RECs and well resourced RECs. The majority of members (56%) are scientists or clinicians who are typically affiliated to the same institution as the health REC. Community representatives account for only 8% of membership. Training needs for health REC members varied widely. Conclusion Most major health RECs in South Africa are well organized given the resource constraints that exist in relation to research ethics in developing countries. However, the gender, racial and occupational diversity of most of these RECs is suboptimal, and most RECs are not constituted in accordance with South African guidelines. Variability in the operations and training needs of RECs is a reflection of apartheid-entrenched influences in tertiary education in SA. While legislation now exists to enforce standardization of research ethics review systems, no provision has been made for resources or capacity development, especially to support historically-disadvantaged institutions. Perpetuation of this legacy of apartheid represents a violation of the principles of justice and equity. (shrink)

What is the environment, and how does it figure in an ethical life? This book is an introduction to the philosophical issues involved in this important question, focussing primarily on ethics but also encompassing questions in aesthetics and political philosophy. Topics discussed include the environment as an ethical question, human morality, meta-ethics, normative ethics, humans and other animals, the value of nature, and nature's future. The discussion is accessible and richly illustrated with examples. The book will be valuable for students (...) taking courses in environmental philosophy, and also for a wider audience in courses in ethics, practical ethics, and environmental studies. It will also appeal to general readers who want a reliable and sophisticated introduction to the field. (shrink)

Pickering & Garrod (P&G) claim that the automatic mechanisms that underlie language processing in dialogue are absent in monologue. We disagree with this claim, and argue that dialogue simply provides a different context in which the same basic processes operate.

In 1963 Niko Tinbergen published a paper, "On Aims and Methods of Ethology," dedicated to his friend Konrad Lorenz. Here Tinbergen defines ethology as "the biological study of behavior," and seeks to demonstrate "the close affinity between Ethology and the rest of Biology." Tinbergen identifies four major areas of ethology: causation, survival value, evolution, and ontogeny. Our goal is to attempt for cognitive ethology what Tinbergen succeeded in doing for ethology: to clarify its aims and methods, to distinguish some of (...) its varieties, and to defend the fruitfulness of the research strategies that it has spawned.

Context: Although ethics consultation is commonplace in United States (U.S.) hospitals, descriptive data about this health service are lacking. Objective: To describe the prevalence, practitioners, and processes of ethics consultation in U.S. hospitals. Design: A 56-item phone or questionnaire survey of the "best informant" within each hospital. Participants: Random sample of 600 U.S. general hospitals, stratified by bed size. Results: The response rate was 87.4%. Ethics consultation services (ECSs) were found in 81% of all general hospitals in the U.S., and (...) in 100% of hospitals with more than 400 beds. The median number of consults performed by ECSs in the year prior to survey was 3. Most individuals performing ethics consultation were physicians (34%), nurses (31%), social workers (11%), or chaplains (10%). Only 41% had formal supervised training in ethics consultation. Consultation practices varied widely both within and between ECSs. For example, 65% of ECSs always made recommendations, whereas 6% never did. These findings highlight a need to clarify standards for ethics consultation practices. (shrink)

In Phenomenology of Spirit (1806) Hegel is often held to have announced the end of history, where 'history' is to be understood as the long pursuit of ends towards which humanity had always been striving. In this, the first book in English to thoroughly critique this entrenched view, Eric Michael Dale argues that it is a misinterpretation. Dale offers a reading of his own, showing how it sits within the larger schema of Hegel's thought and makes room for (...) an understanding of the 'end of history' as Hegel intended. Through an elegant analysis of Hegel's philosophy of history, Dale guides the reader away from the common misinterpretation of the 'end of history' to other valuable elements of Hegel's arguments which are often overlooked and deserve to endure. His book will be of great interest to scholars and advanced students of Hegel, the philosophy of history, and the history of political thought. (shrink)

Robert Myers presents an original moral theory which charts a course between the extremes of consequentialism and contractualism. He puts forward a radically new case for the existence of both agent-neutral and agent-relative values, and gives an innovative answer to the question how such disparate values can be weighed against each other. Practical judgement is shown to be guided in this by two very different ideals: an ideal of cooperation, which is held to shape the content of morality's demands, (...) and one of self-governance, which is held to determine the nature of reason's requirements. Examination of the ideal of cooperation reveals that principles of impartial beneficence and rights protecting individual freedoms are equally fundamental to morality. Examination of the ideal of self-governance reveals that morality's dictates, though not necessarily overriding, are always in an important sense inescapable. The result is a theory of morality which combines a balanced account of its content with a ringing affirmation of its authority. (shrink)

This paper explores the association of children and animals as an element in Western culture's symbolic universe. Three historical discourses found in the West associate animality with immaturity and growing up with the transcendence of this condition. The discourses differ in how they describe and evaluate the original animal-like condition of the child versus the socialized end product. All, however, tend to distinguish sharply between the human and the nonhuman. This paper explores expressions of this tendency in developmental theories that (...) set as the criterion of maturity the actualization of some capacity that is believed to set humans apart from animals. Seeing relationships with animals as marginally important in human development and life is a consequence of these assumptions. Simultaneously, these assumptions also marginalize the body. This constitutes a dual renunciation of body and animal, criticized for its effects both on inquiry and on our realization of the roles and values of nonhuman animals in development. Such research can help reveal the self-organizing nature of the human animal body. (shrink)

This article provides a history of private sector tracking technologies, examining how the advent of commercial surveillance centered around a logic of data capitalism. Data capitalism is a system in which the commoditization of our data enables an asymmetric redistribution of power that is weighted toward the actors who have access and the capability to make sense of information. It is enacted through capitalism and justified by the association of networked technologies with the political and social benefits of online community, (...) drawing upon narratives that foreground the social and political benefits of networked technologies. I examine its origins in the wake of the dotcom bubble, when technology makers sought to develop a new business model to support online commerce. By leveraging user data for advertising purposes, they contributed to an information environment in which every action leaves behind traces collected by companies for commercial purposes. Through analysis of primary source materials produced by technology makers, journalists, and business analysts, I examine the emergence of data capitalism between the mid-1990s and mid-2000s and its central role in the contemporary information economy.

Dale Dorsey considers one of the most fundamental questions in philosophical ethics: to what extent do the demands of morality have normative authority over us and our lives? Must we conform to moral requirements? Most who have addressed this question have treated the normative significance of morality as simply a fact to be explained. But Dorsey argues that this traditional assumption is misguided. According to Dorsey, not only are we not required to conform to moral demands, conforming to morality's (...) demands will not always even be normatively permissible---moral behavior can be wrong. This view is significant not only for understanding the content and force of the moral point of view, but also for understanding the basic elements of how one ought to live. (shrink)
