This paper uses classical logic for a simultaneous description of the syntax and semantics of a fragment of English and it is argued that such an approach to natural language allows procedural aspects of linguistic theory to get a purely declarative formulation. In particular, it will be shown how certain construction rules in Discourse Representation Theory, such as the rule that indefinites create new discourse referents and definites pick up an existing referent, can be formulated declaratively if logic is used (...) as a metalanguage for English. In this case the declarative aspects of a rule are highlighted when we focus on the model theory of the description language while a procedural perspective is obtained when its proof theory is concentrated on. Themes of interest are Discourse Representation Theory, resolution of anaphora, resolution of presuppositions, and underspecification. (shrink)

Pediatric biobanking is considered important for generating biomedical knowledge and improving health care. However, the inclusion of children’s samples in biobanks involves specific ethical issues. One of the main concerns is how to appropriately engage children in the consent procedure. We suggest that children should be involved through a personalized assent procedure, which means that both the content and the process of assent are adjusted to the individual child. In this paper we provide guidance on how to put personalized assent (...) into pediatric biobanking practice and consider both the content and process of personalized assent. In the discussion we argue that the assent procedure itself is formative. Investing in the procedure should be a requirement for pediatric biobank research. Although personalized assent will require certain efforts, the pediatric community must be aware of its importance. The investment and trust earned can result in ongoing engagement, important longitudinal information, and stability in/for the research infrastructure, as well as increased knowledge among its participants about research activity. Implementing personalized assent will both respect the child and support biobank research. (shrink)

The COVID-19 pandemic and its associated stressors have impacted the daily lives and sleeping patterns of many individuals, including university students. Dreams may provide insight into how the mind processes changing realities; dreams not only allow consolidation of new information, but may give the opportunity to creatively “play out” low-risk, hypothetical threat simulations. While there are studies that analyze dreams in high-stress situations, little is known of how the COVID-19 pandemic has impacted dreams of university students. The aim of this (...) study was to explore how the dream content of students was affected during the university COVID-19 lockdown period (March–July, 2020). Using online survey methods, we analyzed dream recall content (n= 71) using the Hall-Van de Castle dream coding system and Fisher's exact tests for sex comparisons. Preliminary results indicate that female students experienced more nightmares as compared to male students. Dream analysis found that, relative to normative American College Student (ACS) samples generated pre-COVID-19, women were more likely to experience aggressive interactions in their dream content, including increased physical aggression. Results indicate that university students did experience changes in dream content due to the pandemic lockdown period, with women disproportionally affected. These findings can aid universities in developing support programs for students by bringing forth an understanding of students' concerns and anxieties as they process the “new normal” of social distancing.

Else Margarete Barth (1928-2015) was een Noors-Nederlandse filosoof.0Else Barth vond dat filosofie in dienst zou moeten staan van de combinatie van medemenselijkheid en helder, geïnformeerd denken en discussiëren. Barth was ervan overtuigd dat zorgvuldig redeneren en debatteren noodzakelijk is voor het verbeteren van menselijke relaties. Met logica als wapen bestreed ze vaagheid en vooroordelen. Om logica van betekenis te maken voor het praktische leven, verbond ze het met analytisch onderzoek naar ideeën die rondwaren in wetenschap en politieke cultuur. Haar bijzondere (...) belangstelling ging daarbij uit naar anti-argumentatieve en anti-parlementaire houdingen en denksystemen die, vaak ten faveure van een hoger doel, minachting voor (groepen) individuen legitimeren of zelfs aanmoedigen. Met haar pleidooi voor een 'empirische logica' leverde Barth een originele bijdrage aan de Europese wijsbegeerte, die ook voor de huidige tijd relevant is.0'Empirische logica' is een selectie uit Barths werk. De bundel bevat voorbeelden van toegepast empirisch-logisch onderzoek, naar de logische grondslagen van het Duitse idealisme bijvoorbeeld, die volgens Barth dezelfde zijn als die van de klassieke homeopathie, naar het denken van de Noorse nazi Quisling, maar ook naar de onevenredige aandacht voor 'gemiddelden' in de sociale wetenschappen, die tot stigmatisering leidt. In beschouwende stukken reflecteert de auteur onder meer op het belang van cultuur-georiënteerd logica-onderwijs en zoekt ze een verklaring voor de kloof tussen logica en politiek. Ten slotte zijn essays0opgenomen die Barth schreef over filosofen die haar inspireerden: Bertrand Russell, Evert Willem Beth en Arne Naess. (shrink)

Studie over het werk van de Nederlandse filosoof Herman Dooyeweerd (1894- 1977).

Both Jean-François Lyotard and Jean-Luc Nancy have tried to understand the law within the heterogeneity of society by means of Kant's notion of 'as if'. Kant introduced this notion in order to respect the gap between reason and intuition; Lyotard and Nancy took it up to explain the lack of unity in society. In the margins of their work — footnotes and postscripts — they have discussed this theme and searched for the presuppositions and risks of each others position, as (...) a result of which the 'as if' is considered from different perspectives and the philosophies of Lyotard and Nancy are illuminated inopposition to each other. Although this discussion commenced in the seventies, this theme is currently more topical than ever as is clear from the development of the Europeanand Iraqi constitutions. An analysis of the complex discussion between Lyotard and Nancy is given to provide insight into the principles that constitute the law. Both Lyotardand Nancy are trying to solve the problem of how to judge without a given rule. Lyotardis mainly concerned with understanding the 'as if' as an attempt to respect heterogeneity, while Nancy criticizes Lyotard for ignoring the constitution of this heterogeneity.Nancy uses the notion of 'dislocation' to understand both every case as an accident andthe neglect of this aspect by the jurisdiction. At the same time, we will elaborate on the reception of the Kantian thinking in French philosophy. Although the importance of well-known notions such as the sublime have been emphasized many times, the relevance of the 'as if' has not been thoroughly investigated. It will be shown that the notion ofthe 'as if' can be fruitful for understanding the creative element of jurisdiction, that is, for judging without rules. (shrink)

Volume 1 of this biography of L. E. J. Brouwer was published in 1999.1 The volume under review here covers the period from the early nineteen twenties until Brouwer's death in 1966. It also includes a short epilogue that discusses the disposition of Brouwer's estate after his death, his influence on others, the paths of some of his students and colleagues, and other matters. Van Dalen notes in the Preface that in preparing this volume he consulted some historical studies that (...) appeared after the first volume was published. He also used new material from various archives. The biography contains interesting quotations from unpublished materials in the Brouwer Archive and from correspondence. The bibliographical references to Brouwer's publications, it should be noted, are somewhat different in this volume. This volume, like the first, contains some nice photographs and reproductions. I noted that there were many typographical errors in the earlier book but Volume 2 is relatively free of them.As is the case in Volume 1, the discussion of Brouwer's mathematical and philosophical work is woven into the narrative of Brouwer's life and times. The story in this volume starts with Brouwer's first contacts with Paul Alexandrov and Paul Urysohn in 1923. The interaction began when Urysohn announced that he had found a mistake in Brouwer's definition of dimension in Brouwer's 1913 paper on natural dimension. Was it just a slip of the pen, as Brouwer always maintained, or something more substantial? Urysohn and Alexandrov ultimately came to agree with Brouwer on the matter, and Urysohn was prepared to grant Brouwer priority for the definition of dimension. There were, however, ups and downs along the way. Karl Menger, through his own work in topology and dimension theory, soon got into the picture, and Brouwer and Menger were to …. (shrink)

The thesis developed and defended in this paper is that is it false that all knowledge is founded on experience. Much of our knowledge (or alleged knowledge), it is argued, is based on testimony. Still, many philosophers have either not dealt with testimony at all, or treated it very unkindly. One of the reasons for this is that those philosophers (such as Descartes and Locke) work with a concept of knowledge according to which knowledge is certain, indubitable, and/or self-evident. And (...) if knowledge is what these philosophers say it is, then there is no such thing as knowledge based on testimony indeed. Thomas Reid is introduced as holding that we do have testimonial knowledge and that therefore Descartes' and Locke's concept of knowledge is untenable. Reid furthermore holds that human beings are endowed with a disposition to accept or believe what otherstell us („the principle of credulity”). The working of this principle is refined through all kinds of experience. What Reid says or shows is how this disposition in fact operates. Many epistemologists, however, have higher aspirations and look for reasons or arguments that can justify our factual acceptance of testimony. The inductive argument Hume offers, it is argued, is unconvincing. There is even reason to think that the principle of credulity can never be justified by adducing reasons. This does not imply, however, that acceptance of testimony is unjustified. Whether or not it is depends, among other things, on the concept of justification one uses. On an internalist concept of justification (as Locke's or Hume's) this disposition may never be justified. But on an externalist conception it may. This may be disappointing, given some widely held philosophical aspirations, but at the same time it is, as Alston has said, a lesson in intellectual humility. (shrink)

Psillos has recently argued that van Fraassen’s arguments against abduction fail. Moreover, he claimed that, if successful, these arguments would equally undermine van Fraassen’s own constructive empiricism, for, Psillos thinks, it is only by appeal to abduction that constructive empiricism can be saved from issuing in a bald scepticism. We show that Psillos’ criticisms are misguided, and that they are mostly based on misinterpretations of van Fraassen’s arguments. Furthermore, we argue that Psillos’ arguments for his claim that constructive empiricism itself (...) needs abduction point up to his failure to recognize the importance of van Fraassen’s broader epistemology for constructive empiricism. Towards the end of our paper we discuss the suspected relationship between constructive empiricism and scepticism in the light of this broader epistemology, and from a somewhat more general perspective.

Considering Pragma-Dialectics honors the monumental contributions of one of the foremost international figures in current argumentation scholarship: Frans van Eemeren. The volume presents the research efforts of his colleagues and addresses how their work relates to the pragma-dialectical theory of argumentation with which van Eemeren’s name is so intimately connected. This tribute serves to highlight the varied approaches to the study of argumentation and is destined to inspire researchers to advance scholarship in the field far into the future. Replete with (...) contributions from highly-esteemed academics in argumentation study, chapters in this volume address such topics as: *Pragma-dialectic versus epistemic theories of arguing and arguments; *Pragma-dialectics and self-advocacy in physician-patient interactions; *The pragma-dialectical analysis of the ad hominem family; *Rhetoric, dialectic, and the functions of argument; and *The semantics of reasonableness. As an exceptional volume and a fitting tribute, this work will be of interest to all argumentation scholars considering the astute insights and scholarly legacy of Frans van Eemeren. (shrink)
