In this position paper, we describe a number of methodological and philosophical challenges that arose within our interdisciplinary Digital Humanities project CatVis, which is a collaboration between applied geometric algorithms and visualization researchers, data scientists working at OCLC, and philosophers who have a strong interest in the methodological foundations of visualization research. The challenges we describe concern aspects of one single epistemic need: that of methodologically securing (an increase in) trust in visualizations. We discuss the lack of ground truths in (...) the (digital) humanities and argue that trust in visualizations requires that we evaluate visualizations on the basis of ground truths that humanities scholars themselves create. We further argue that trust in visualizations requires that a visualization provides provable guarantees on the faithfulness of the visual representation and that we must clearly communicate to the users which part of the visualization can be trusted and how much. Finally, we discuss transparency and accessibility in visualization research and provide measures for securing transparency and accessibility. (shrink)

Inleiding vanuit historisch perspectief tot de rechtsfilosofie.

Aggleton & Brown propose that familiarity-based recognition depends on a perirhinal-medial dorsal thalamic system. However, connections between these structures are sparse or absent. In contrast, the perirhinal cortex is connected to midline/intralaminar nuclei. In a human, a lesion in this thalamic domain, sparing the medial dorsal nucleus, impaired familiarity-based recognition while sparing recollective-based recognition. It is thus more likely that the intralaminar/midline nuclei are involved in recognition.

One widespread argument against the efficacy of subjective well-being as a measure of well-being is the adaptation problem as formulated by Sen and Nussbaum: the phenomenon that people may adapt to deprivation and find satisfaction or happiness in objectively bad circumstances. It is not generally noticed that there are two distinct arguments for why the phenomenon of adaptation is a problem for subjective well-being as a measure of well-being. The Axiological Adaptation Argument is a counter-example to theories of well-being that (...) rely on mental states. The Epistemic Adaptation Argument illustrates that levels of happiness or satisfaction cannot be measured well when people have adapted. I argue that the most serious threat to subjective well-being measures is not the Axiological Argument, but the Epistemic Argument. I reflect on the implications the epistemic problem has for the empirical literature in general, and for research on the phenomenon of adaptation in particular. (shrink)

Results of two survey studies are presented. It is shown that attitudes of the public about "technology in general" are not stable and can easily be affected by how the subject is introduced. Eight areas of technology are compared on the basis of empirical relations in attitudinal judgments, in attribute ratings, in self- assigned importance weights of attributes, and in importance of reference groups and persons. On the basis of similarities in these four kinds of judgments, three clusters of technology (...) areas were identified: a cluster of modern reproductive technologies, an information cluster containing automation, computer, and communication technologies, and a cluster containing nuclear energy and military technology. The attitude toward "technology in general" can not be considered as an aggregation of attitudes toward these areas of technology: The relations between general attitude and specific attitudes are only moderate to negligible.

Exploration of Alfred North Whitehead's influence on Maurice Merleau-Ponty's ontology of nature.

Legal and moral reasoning share much methodology, and they address similar problems. This volume charts two shared problems: the relation between theory, principles and particular judgments; and the role of facts and factual assertions in normative settings. The relation between 'theory' and 'practice' and between 'principle' and 'particular judgment' has become the subject of much debate in moral philosophy. In the ongoing debate, some moral philosophers refer to legal philosophy for a support of their views on the primacy of 'practice' (...) over 'theory'. According to them, legal philosophy should have a more balanced view in that relation. In the contributions to Part One this claim is critically analysed. The role of the facts is underestimated in discussions on legal reasoning and legal theory, as well as moral reasoning and ethical theory. Factual statements enter into moral and legal discussions not only because they link the conclusion with a rule. They also play a role as background assumptions in supporting a theory. Its focus on the role of facts in normative reasoning makes this book of special interest to scholars of legal and moral argumentation. (shrink)

In the present work we illustrate how two sorts of defeasible reasoning that are fundamental in the normative domain, that is, reasoning about exceptions and reasoning about violations, can be simulated via monotonic propositional theories based on a bimodal language with primitive operators representing knowledge and obligation. The proposed theoretical framework paves the way to using native theorem provers for multimodal logic, such as MleanCoP, in order to automate normative reasoning.

Many researchers studying subjective wellbeing (SWB) understand SWB as a concept that is close to Bentham’s notion of happiness. This conception of happiness is philosophically controversial, because it treats pleasure as a homogenous experience. I analyze an important deviation from Bentham in John Stuart Mill’s Utilitarianism and its relevance for SWB research: qualitative differences in pleasurable experiences. I argue that in cases where lives involving qualitatively different experiences are compared, Mill’s qualitative perspective is incompatible with an important assumption in the (...) SWB literature: that happiness can be meaningfully rated by people on a scale. I illustrate the problem by means of the question of whether becoming a parent makes people happier. I analyze whether the problem can be avoided on alternative views of happiness, but argue that on all plausible accounts of happiness, the problem persists. I conclude that the problem it poses for self-reported happiness is genuine and should be acknowledged by SWB researchers. I end by discussing the ways in which this conclusion can help the study of happiness move forward. (shrink)

Four experiments examined the strategies that individuals develop in sentential reasoning. They led to the discovery of five different strategies. According to the theory proposed in the paper, each of the strategies depends on component tactics, which all normal adults possess, and which are based on mental models. Reasoners vary their use of tactics in ways that have no deterministic account. This variation leads different individuals to assemble different strategies, which include the construction of incremental diagrams corresponding to mental models, (...) and the pursuit of the consequences of a single model step by step. Moreover, the difficulty of a problem (i.e., the number of mental models required by the premises) predisposes reasoners towards certain strategies. Likewise, the sentential connectives in the premises also bias reasoners towards certain strategies, e.g., conditional premises tend to elicit reasoning step by step whereas disjunctive premises tend to elicit incremental diagrams.

This article presents the results of a qualitative study on the ethical aspects of inclusion practice for radiotherapy patients taking part in clinical research. The study focused on the standards and values of this process. Patients and physicians were interviewed about their views and experiences. Analysis of these interviews showed that candidate research participants need better protection from unwanted factors that could influence their choice about participation. Researchers need proper education about regulation, codes and directives in the field of research (...) ethics, and they should be aware of the underlying ethical concepts of these regulations. A sound institutional ethics policy is necessary in order to guide medical staff in decisions about the inclusion of patients in trials. (shrink)

The scientific advances made in the last two centuries have drastically improved the quality and structure of human existence. Exploring the history of that technological progress, and the numerous and complex elements that propelled its development, the _Encyclopedia of Technological Progress_ attempts to comprehensively classify the theories and hypotheses proposed in modern human history on the effects, meaning, and control of these advances. This massive and learned reference work draws on a wide range of disciplines in its study of technological (...) development, including philosophy, sociology, theology, history, and literature, as well as writings found in newspapers, political speeches, letters, and sermons, among other sources. “It is exceedingly important... that we should seek to understand more deeply the nature of technological development and very timely that this book should have appeared now to give distance and perspective to our efforts in this direction.”—Alexander King, president of the Club of Rome.

In this paper we study AGM contraction and revision of rules using input/output logical theories. We replace propositional formulas in the AGM framework of theory change by pairs of propositional formulas, representing the rule based character of theories, and we replace the classical consequence operator Cn by an input/output logic. The results in this paper suggest that, in general, results from belief base dynamics can be transferred to rule base dynamics, but that a similar transfer of AGM theory change to (...) rule change is much more problematic. First, we generalise belief base contraction to rule base contraction, and show that two representation results of Hansson still hold for rule base contraction. Second, we show that the six so-called basic postulates of AGM contraction are consistent only for some input/output logics, but not for others. In particular, we show that the notorious recovery postulate can be satisfied only by basic output, but not by simple-minded output. Third, we show how AGM rule revision can be defined in terms of AGM rule contraction using the Levi identity. We highlight various topics for further research. (shrink)

Due to its extraordinary predictive power and the great generality of its mathematical structure, quantum theory is able, at least in principle, to describe all the microscopic and macroscopic properties of the physical world, from the subatomic to the cosmological level. Nevertheless, ever since the Copen hagen and Gottingen schools in 1927 gave it the definitive formu lation, now commonly known as the orthodox interpretation, the theory has suffered from very serious logical and epistemologi cal problems. These shortcomings were immediately (...) pointed out by some of the principal founders themselves of quantum theory, to wit, Planck, Einstein, Ehrenfest, Schrodinger, and de Broglie, and by the philosopher Karl Popper, who assumed a position of radical criticism with regard to the standard formulation of the theory. The aim of the participants in the workshop on Open Questions in Quantum Physics, which was held in Bari (Italy), in the Department of Physics of the University, during May 1983 and whose Proceedings are collected in the present volume, accord ingly was to discuss the formal, the physical and the epistemo logical difficulties of quantum theory in the light of recent crucial developments and to propose some possible resolutions of three basic conceptual dilemmas, which are posed respectively ~: (a) the physical developments of the Einstein-Podolsky-Rosen argument and Bell's theorem, i. e.
