The topic of temporal meaning in texts has received considerable attention in recent years from scholars in linguistics, logical semantics, cognitive science, and artificial intelligence. Representing Time in Natural Language offers a systematic and detailed account of how we use temporal information contained in a text or in discourse to reason about the flow of time, inferring the order in which events happened when this is not explicitly stated. A new representational system is designed to formalize an appropriately context-dependent notion (...) of situated inference. The Dynamic Aspect Tree, representing temporal dependencies, constitutes a novel and important dynamic temporal logic, one that makes it easy to see "what follows when" from the information given in an ordinary English text.

Validity of dynamic temporal reasoning is semantically characterized for English and Dutch aspectual adverbs in Discourse Representation Theory. This dynamic perspective determines how the content needs to be revised and what information is preserved across updates, when the order of premises is considered relevant. Resetting contextual parameters relies on modelling the basic aspectual polarity transitions and temporal reasoning extensionally. For intensional aspectual adverbials the speaker’s attitudes regarding past alternatives to and possible continuations of the current state come into play. Additional (...) considerations are offered for generalizing this system to the full logical space for linguistic universals, lexicalized quite differently in Dutch and English. (shrink)

Meaning is made out of the world by our actions in certain situations. But there are so many different things we can do, few of which actually create meaning. Not only do we utter linguistic expressions, but we move, gesture, point; we plan our actions to satisfy particular goals, we form beliefs, presumptions and prejudices, as well as ascribe intentions to other actors. In this paper three ways of acting are singled out for their function in making meaning out of (...) the world: demonstrations, indications and experiments. The paper develops some Wittgensteinean themes, such as the priority of demonstration, the nature of pictorial representations and the relation between interpretation and calculation, in the terms and concepts of Situation Theory. It attempts to weave some important elements of Wittgenstein’s thought in with an account of situated meaning and interpretation, without embarking on any archeological adventure. The paper is intended as a contribution to the philosophical foundations of Situation Theory and a critical commentary to some of its published accounts. Although Situation Theory has been developed with a sharp awareness of its antecedents in Bertrand Russell’s work, as well as its immediate heritage of central aspects of David Kaplan’s account of demonstrative reference, to my knowledge its Wittgensteinean roots have not been traced. The account of demonstrations, indications and experiments advocated here shows not only that important philosophical concerns of Situation Theory have their precursors in Wittgenstein’s work, but also that some of his insights could profitably be absorbed into its new foundations for a theory of meaning.

This selection of research papers written by Hans Kamp presents the core of his scientific research on natural language semantics and its relation to logic, philosophy and linguistics. Arranged in six sections, the topics range from philosophical reflection on the foundational issues in the ancient Sorites Paradox with a formal account of its solution, to a detailed account of presuppositions in dynamic semantics.

Modelling human reasoning characterizes the fundamental human cognitive capacity to describe our past experience and use it to form expectations as well as plan and direct our future actions. Natural language semantics analyzes dynamic forms of reasoning in which the real-time order determines the temporal relations between the described events, when reported with telic simple past-tense clauses. It provides models of human reasoning that could supplement ACT-R models.

In designing stratified models of human language, understanding notions of logical consequence and validity of inference require separating the aspects of meaning that vary between models from logical constants. Modelling meaning requires choices regarding the primitives, where the Fregean program is still offering us the fundamental insights on the role of truth, judgement, and grasping or sharing of thoughts.

Semantic realism fits Millikan's account of kind terms in its focus on information-theoretic abilities and strategic ways of gathering information in human communication. Instead of the traditional logical necessity, we should interpret rigid designation in a dynamic semantics as a legislative act to constrain possible ways in which our belief may change.

In the modular design of generative theory the syntax-semantics interface has accounted all along for meanings at the level of Logical Form. The syntax-pragmatics interface, on the other hand, is the result of what one may call the 'pragmatic turn' in the linguistic theory, where content is partitioned into given and new information. In other words, the structural division of the clause has been subjected to criteria of information, or discourse structure. Both interfaces require a structurally descriptive inventory whose specific (...) shapes can be motivated on theory-internal grounds only. The present collection of original articles develops the concept of these interfaces further. The papers in the first section focus on the syntax-semantics interface, those in the second section on the syntax-pragmatics interface. (shrink)

This Handbook documents the main trends in current research between logic and language, including its broader influence in computer science, linguistic theory and cognitive science. The history of the combined study of Logic and Linguistics goes back a long way, at least to the work of the scholastic philosophers in the Middle Ages. At the beginning of this century, the subject was revitalized through the pioneering efforts of Gottlob Frege, Bertrand Russell, and Polish philosophical logicians such as Kazimierz Ajdukiewicz. Around (...) 1970, the landmark achievements of Richard Montague established a junction between state-of-the-art mathematical logic and generative linguistic theory. Over the subsequent decades, this enterprise of Montague Grammar has flourished and diversified into a number of research programs with empirical and theoretical substance. This appears to be the first Handbook to bring logic-language interface to the fore. Both aspects of the interaction between logic and language are demonstrated in the book i.e. firstly, how logical systems are designed and modified in response to linguistic needs and secondly, how mathematical theory arises in this process and how it affects subsequent linguistic theory. The Handbook presents concise, impartial accounts of the topics covered. Where possible, an author and a commentator have cooperated to ensure the proper breadth and technical content of the papers. The Handbook is self-contained, and individual articles are of the highest quality. (shrink)

Background: Issues concerning legislation and regulation with respect to the role of nurses in euthanasia and physician-assisted suicide gave the Minister for Health reason to commission a study of the role of nurses in medical end-of-life decisions in hospitals, home care and nursing homes.Aim: This paper reports the findings of a study of the role of nurses in euthanasia and physician-assisted suicide, conducted as part of a study of the role of nurses in medical end-of-life decisions. The findings for hospitals, (...) home care and nursing homes are described and compared.Method: A questionnaire was sent to 1509 nurses, employed in 73 hospitals, 55 home care organisations and 63 nursing homes. 1179 responses were suitable for analysis. The questionnaire was pilot-tested among 106 nurses, with a response rate of 85%.Results: In 37.0% of cases, the nurse was the first person with whom patients discussed their request for euthanasia or physician-assisted suicide. Consultation between physicians and nurses during the decision-making process took place quite often in hospitals and nursing homes and less frequently in home care situations . In some cases , nurses administered the euthanatics.Conclusions: The results show substantial differences between the intramural sector and the extramural sector , which are probably linked to the organisational structure of the institutions. Consultation between physicians and nurses during the decision-making process needs improvement, particularly in home care. Some nurses had administered euthanatics, although this task is by law exclusively reserved to physicians. (shrink)

This article reports the findings of a study into the role of Dutch nurses in the alleviation of pain and symptoms with a life-shortening intention, conducted as part of a study into the role of nurses in medical end-of-life decisions. A questionnaire survey was carried out using a population of 1509 nurses who were employed in hospitals, home care organizations and nursing homes. The response rate was 82.0%; 78.1% were suitable for analysis. The results show that in about half of (...) the cases nurses were involved in the decision making by the physician and that nurses were frequently involved in administering the medication. The authors' conclusion is that alleviation of pain and symptoms with a life-shortening intention represents a `grey' area, in which physicians and nurses act on the basis of personal ethical norms rather than legal rules, professional guidelines or shared moral values.

Elementary set theory accustoms the students to mathematical abstraction, includes the standard constructions of relations, functions, and orderings, and leads to a discussion of the various orders of infinity. The material on logic covers not only the standard statement logic and first-order predicate logic but includes an introduction to formal systems, axiomatization, and model theory. The section on algebra is presented with an emphasis on lattices as well as Boolean and Heyting algebras. Background for recent research in natural language semantics (...) includes sections on lambda-abstraction and generalized quantifiers. Chapters on automata theory and formal languages contain a discussion of languages between context-free and context-sensitive and form the background for much current work in syntactic theory and computational linguistics. The many exercises not only reinforce basic skills but offer an entry to linguistic applications of mathematical concepts. For upper-level undergraduate students and graduate students in theoretical linguistics, computer-science students with interests in computational linguistics, logic programming and artificial intelligence, mathematicians and logicians with interests in linguistics and the semantics of natural language.

Logicians have always found inspiration for new research in the ordinary language that is used on a daily basis and acquired naturally in childhood. Whereas the logical issues in the foundations of mathematics motivated the development of mathematical logic with its emphasis on notions of proof, validity, axiomatization, decidability, consistency, and completeness, the logical analysis of natural language motivated the development of philosophical logic with its emphasis on semantic notions of presupposition, entailment, modality, conditionals, and intensionality. The relation between research (...) programs in both mathematical and philosophical logic and natural language syntax and semantics as branches of theoretical linguistics has increased in importance throughout the last fifty years. This chapter reviews the development of one particularly interesting and lively area of interaction between formal logic and linguistics—the semantics of natural language. Research in this emergent field has proved fruitful for the development of empirically, cognitively adequate models of reasoning with partial information, sharing or exchanging information, dynamic interpretation in context, belief revision and other cognitive processes.

The transhumanist literature encompasses diverse nonnovel positions on questions of disability and obligation reflecting long-running political philosophical debates on freedom and value choice, complicated by the difficulty of projecting values to enhanced beings. These older questions take on a more concrete form given transhumanist uses of biotechnologies. This paper will contrast the views of Hughes and Sandberg on the obligations persons with "disabilities" have to enhance and suggest a new model. The paper will finish by introducing a distinction between the (...) responsibility society has in respect of the presence of impairments and the responsibility society has not to abandon disadvantaged members, concluding that questions of freedom and responsibility have renewed political importance in the context of enhancement technologies.

Concern for and interest in research integrity has increased significantly during recent decades, both in academic and in policy discourse. Both in terms of diagnostics and in terms of therapy, the tendency in integrity discourse has been to focus on strategies of individualisation. Other contributions to the integrity debate, however, focus more explicitly on environmental factors, e.g. on the quality and resilience of research ecosystems, on institutional rather than individual responsibilities, and on the quality of the research culture. One example (...) of this is the Bonn PRINTEGER Statement. This editorial to the LSSP thematic series entitled Addressing integrity challenges in research: the institutional dimension invites authors to contribute to the research integrity debate. Notably, we are interested in submissions addressing issues such as institutional responsibilities, changes in the research climate, duties of research managers and research performing or research funding organisations as well as new approaches to integrity education.

The essays collected in this volume, appearing between the years 1939 and 1958, include all of the late Professor J. L. Austin's published papers, and in addition two unpublished papers, ‘The Meaning of a Word’ and ‘Unfair to Facts’, as well as an unscripted talk, ‘Performative Utterances’, given in the Third Programme of the B.B.C. in 1956. The editors, J. O. Urmson and G. J. Warnock, have performed a real service in making these papers available in one volume; for the (...) cumulative impact of the method Austin pursued in doing philosophy, and the questions this method raises, can be felt and appreciated more fully when a considerable assemblage of illustrative papers is brought together. The debt Austin owes to the tradition to which G. E. Moore and Wittgenstein contributed is quite clear, and the divergences from them are equally clear. In reviewing the contents of the ten articles in this volume I shall try to single out what is unique about his contribution, in particular what features of his procedure, falling as it does under the general classification ‘linguistic analysis’, were so distinctive as to win for it the attention accorded to a new departure.

This article presents various developments in Dutch health care policy toward a greater role for individual financial responsibility, such as cost-control measures, priority setting, rationing, and market reform. Instead of the collective responsibility that is characteristic of previous times, one can observe in government policies an increased emphasis on the need for individuals to take care of one’s own health and health care needs. Moreover, surveys point to decreasing levels of public support for “unlimited” solidarity and “irresponsible” health behavior. This (...) article attempts to answer the question of how these policies and public attitudes are limiting the ethical principles of solidarity and equal access to care that have long guided Dutch health care policy making. The authors argue that from a moral point of view, the increased emphasis on individual responsibility is acceptable as long as it does not affect solidarity with those weak and vulnerable groups who are not able to take individual responsibility, such as the demented and mentally handicapped.

Solidarity has for a long time been referred to as the core value underpinning European health and welfare systems. But there has been debate in recent years about whether solidarity, with its alleged communitarian content, can be reconciled with the emphasis on individual freedom and personal autonomy. One may wonder whether there is still a place for solidarity, and whether the concept of justice should be embraced to analyse the moral issues regarding access to health care. In this article, I (...) will answer this question by analysing the normative foundations of the concept of justice, followed by a deeper examination of the concept of solidarity in continental philosophy. More specifically, I will compare the philosophical traditions rooted in Kant to approaches rooted in Hegel. In addition, I will present the work of Avishai Margalit on the decent society to criticize a predominantly liberal approach to access to health care. The importance of solidarity lies particularly in its emphasis on relational aspects and the role of recognition in care practices, which are usually ignored in liberal approaches to justice. However, the article will argue that solidarity is not an alternative to a rights-based concept of justice, but must be considered as a necessary complement to it. (shrink)
