Vegetarians are often charged with inconsistency. They are told that, if they refrain from meat consumption, they should also refrain from the consumption of all animal products. The central question this paper addresses is whether the requirement of consistency means that vegetarians should become vegans. It is argued that if a vegetarian is motivated by arguments that focus on animals, she is indeed inconsistent and should become a vegan.

By sounding the work of John Calvin and Karl Barth as mirrors of reflection and experience, justice is done to the tension between the premodern and postkantian ...

This work details the theological sources and moral significance of the life and work of the Scottish moral philosopher Adam Smith (1723-1790). The panel of contributors deepen our understanding of Adam Smith in his religious and theological context and the significance of this understanding for contemporary moral, economic, and political challenges to modern social life. The chapters cover a broad range of disciplinary and historical concerns, from Smith's view of providence and his famous "invisible hand" to the role of self-interest (...) and benevolence in Smith's social and economic thought. A better appreciation for the moral and theological dimensions of Smith's thought provides not only a better understanding of Smith's own context and significance in the Scottish Enlightenment, but also promises to assist in meeting the perennial challenges of properly connecting economic realities to moral responsibility. The book is of interest to advanced students and scholars of the history of economic thought, historical and moral theology, intellectual history, political science and philosophy. (shrink)

Concrete examples and epistemic puzzles enliven the exposition. The book also offers exercises with answers. It is suitable for graduate courses in logic. Many examples, exercises, and thorough completeness proofs and expressivity results are included. A companion web page offers slides for lecturers and exams for further practice.

Libertarians often bill their theory as an alternative to both the traditional Left and Right. _The Routledge Handbook of Libertarianism_ helps readers fully examine this alternative, without preaching it to them, exploring the contours of libertarian thinking on justice, institutions, interpersonal ethics, government, and political economy. The 31 chapters--all written specifically for this volume--are organized into five parts. Part I asks, what should libertarianism learn from other theories of justice, and what should defenders of other theories of justice learn from (...) libertarianism? Part II asks, what are some of the deepest problems facing libertarian theories? Part III asks, what is the right way to think about property rights and the market? Part IV asks, how should we think about the state? Finally, part V asks, how well can libertarianism deal with some of the major policy challenges of our day, such as immigration, trade, religion in politics, and paternalism in a free market. Among the _Handbook_’s chapters are those from critics who write about what they believe libertarians get right as well as others from leading libertarian theorists who identify what they think libertarians get wrong. As a whole, the _Handbook_ provides a comprehensive, clear-eyed look at what libertarianism has been and could be, and why it matters. (shrink)

There is a claim that clinical ethics support services (CESS) improve healthcare quality within healthcare organisations. However, there is lack of strong evidence supporting this claim. Rather, the current focus is on the quality of CESS themselves or on individual learning outcomes. In response, this article proposes a theoretical framework leading to empirical hypotheses that describe the relationship between a specific type of CESS, moral case deliberation and the quality of care at the organisational level. We combine insights from the (...) literature on CESS, organisational learning and quality improvement and argue that moral case deliberation causes healthcare professionals to acquire practical wisdom. At the organisational level, where improving quality is a continuous and collective endeavour, this practical wisdom can be aggregated into morisprudence, which is an ongoing formulation of moral judgements across cases encountered within the organisation. Focusing on the development of morisprudence enables refined scrutinisation of CESS-related quality claims. (shrink)

This contribution is a gentle introduction to so-called dynamic epistemic logics, that can describe how agents change their knowledge and beliefs. We start with a concise introduction to epistemic logic, through the example of one, two and finally three players holding cards; and, mainly for the purpose of motivating the dynamics, we also very summarily introduce the concepts of general and common knowledge. We then pay ample attention to the logic of public announcements, wherein agents change their knowledge as the (...) result of public announcements. One crucial topic in that setting is that of unsuccessful updates: formulas that become false when announced. The Moore-sentences that were already extensively discussed at the conception of epistemic logic in Hintikka’s ‘Knowledge and Belief’ give rise to such unsuccessful updates. After that, we present a few examples of more complex epistemic updates. Our closing observations are on recent developments that link the ‘standard’ topic of belief revision, as in ‘On the Logic of Theory Change: partial meet contraction and revision functions’, by Alchourron et al. , to the dynamic epistemic logics introduced here.

Populist attributions of blame have important effects on citizens’ attitudes, cognitions, emotions, and behaviors. Extending previous studies that have mostly looked at populist messages blaming political elites, we use an online survey experiment (N = 805) to investigate the effects of blaming different elitist actors in populist and non-populist ways: (1) political elites, (2) corporate elites, (3) scientific elites, and (4) a combination of these elites. We compare mere causal responsibility attribution to populist blame attributions that highlight a central opposition (...) between “pure ordinary people” and “corrupt elites” to tease out the specific effect of populist rhetoric. Results suggest that populist messages blaming all elites have stronger effects than isolated cues. Furthermore, populist blame attribution leads to more negative perceptions of the elites than non-populist blame attribution. The finding that populist frames can – under some conditions – activate negative perceptions toward different elites is alarming in times of declining trust in societal institutions, and calls for a more encompassing understanding of populists’ scapegoats.

Colour has been shown to facilitate the recognition of scene images, but only when these images contain natural scenes, for which colour is ‘diagnostic’. Here we investigate whether colour can also facilitate memory for scene images, and whether this would hold for natural scenes in particular. In the first experiment participants first studied a set of colour and greyscale natural and man-made scene images. Next, the same images were presented, randomly mixed with a different set. Participants were asked to indicate (...) whether they had seen the images during the study phase. Surprisingly, performance was better for greyscale than for coloured images, and this difference is due to the higher false alarm rate for both natural and man-made coloured scenes. We hypothesized that this increase in false alarm rate was due to a shift from scrutinizing details of the image to recognition of the gist of the image. A second experiment, utilizing images without a nameable gist, confirmed this hypothesis as participants now performed equally on greyscale and coloured images. In the final experiment we specifically targeted the more detail-based perception and recognition for greyscale images versus the more gist-based perception and recognition for coloured images with a change detection paradigm. The results show that changes to images are detected faster when image-pairs were presented in greyscale than in colour. This counterintuitive result held for both natural and man-made scenes and thus corroborates the shift from more detailed processing of images in greyscale to more gist-based processing of coloured images.

Worldwide, church membership is decreasing. A decline in the number of young adults that attend church services is also evident. The purpose of the research was to determine whether the application of a well-established body of knowledge of marketing theories and principles could be used by churches to encourage young adults to return to the church. The application of services marketing to the church as a non-profit organisation is discussed by focussing on non-physical and physical atmospheric cues in the church's (...) servicescape that could enhance church attendance. A quantitative approach was used by testing the opinions of 200 church service attendees of different denominations. The findings indicated that certain elements in the servicescape of a church may be useful in attracting young adults. It was found that music is a strong determinant of whether young adults attend church services, followed by layout and design of the church and then by the signs and symbols used in the church. Females reported significantly higher levels of positive perceptions concerning the layout and design. Although the research showed that some marketing elements, such as a positive servicescape, could improve church attendance, other personal elements such as forming personal relationships with fellow Christians and God need to be further explored.

Society has already seen multiple potential futures of neurotechnologies through the multifaceted lens of science fiction. We do not know which of those futures we will come to live, but the strong force in society's evolutionary process will likely continue to be the insight and oversight developed by the bioethics community, pushing and being pushed by the advances of technology, improvements in medical care, and market competitiveness.

This article addresses the research question: “How do Dutch highly educated Muslim women of Moroccan descent use prayer in dealing with problems?” The theoretical framework was mainly based on the work of Pargament et al. regarding religious coping. The empirical part of the study consisted of a quantitative and a qualitative part. This article presents results of the quantitative part. For the quantitative part of our research, 177 questionnaires were collected using snowball sampling. We asked respondents about their praying practices (...) and their ways of religious coping, using the Brief RCOPE. The connection and communication in their prayer with a loving, caring, benevolent God is the main religious way in which these Muslim women of Moroccan descent cope with all kinds of problems. This use of prayer as a way of coping can be clarified through the psychological functions of religiosity and prayer that are suggested by Pargament, Koenig, and Perez. Prayer could help them in: finding meaning, being master over their circumstances and controlling their emotions, finding comfort and closeness to God, experiencing intimacy with others and closeness to God, and transforming their way of life. We did find few negative religious coping strategies, such as negative feelings towards God or alienation. This is in line with research results of Abu Raiya and Pargament. As Islam implies surrender to God, it may be difficult for Muslims to admit their religious distress, doubts, and struggles. (shrink)

Health technology assessment (HTA) is often biased in the sense that it neglects relevant perspectives on the technology in question. To incorporate different perspectives in HTA, we should pursue agreement about what are relevant, plausible, and feasible research questions; interactive technology assessment (iTA) might be suitable for this goal. In this way a kind of procedural ethics is established. Currently, ethics too often is focussed on the application of general principles, which leaves a lot of confusion as to what really (...) is the matter in specific cases; in an iTA clashes of values should not be approached by use of such ethics. Instead, casuistry, as a tool used within the framework of iTA, should help to articulate and clarify what is the matter, as to make room for explication and consensus building. (shrink)

Background: Although genetic research into Alzheimer disease (AD) is increasing, the ethical aspects of this kind of research and the differences between ethical issues related to genetic and non-genetic research into AD have not yet received much attention. Objectives: (1) To identify and compare the five ethical issues considered most important by surveyed expert panellists in non-genetic and genetic AD research and (2) to compare our empirical findings with ethical issues in genetic research in general as described in the literature. (...) Method: A modified Delphi study in two rounds Results: Genetic and non-genetic research into AD generated an approximately equal number of topics with a considerable overlap. Different priorities in the ethics of both types of research were found. Genetic research raised new topics such as “confidentiality of genetic information” and “implications of research for relatives” which changes the impact and application of existing ethical topics such as “informed consent” and is judged to have more impact on both individuals and society. A difference with the results of more theoretical approaches on ethical aspects related to AD research was also found. Conclusions: Different priorities are given to ethical issues in genetic and non-genetic research. These arise partly because genetic research causes unique and new questions, mostly related to the position of family members and the status of and access to genetic information. Differences found between the results of our empirical study and the more theoretical literature, suggest an additional value for empirical research in medical ethics. (shrink)

In the recently published Papyrus Bodmer 30 one of the six poems deals with the story of Genesis 22. At many places the poem drastically deviates from the biblical text, and the editors of the papyrus are insufficiently aware of the background of these deviations. In this article the authors demonstrate that almost all of them have their background in a centuries long process of both Jewish and Christian reflection on this biblical chapter. It is the very specific ‘Wirkungsgeschichte’ of (...) Gen. 22 that explains most of the poem’s specifics. (shrink)

Interactive technology assessment (iTA) provides an answer to the ethical problem of normative bias in evaluation research. This normative bias develops when relevant perspectives on the evaluand (the thing being evaluated) are neglected. In iTA this bias is overcome by incorporating different perspectives into the assessment. As a consequence, justification of decisions based on the assessment is provided by stakeholders having achieved agreement. In this article, agreement is identified with wide reflective equilibrium to show that it indeed has the potential (...) of justifying decisions. We work out several conditions for this agreement to be achievable and just. (shrink)

Current dynamic-epistemic logics model different types of information change in multi-agent scenarios. We generalize these logics to a probabilistic setting, obtaining a calculus for multi-agent update with three natural slots: prior probability on states, occurrence probabilities in the relevant process taking place, and observation probabilities of events. To match this update mechanism, we present a complete dynamic logic of information change with a probabilistic character. The completeness proof follows a compositional methodology that applies to a much larger class of dynamic-probabilistic (...) logics as well. Finally, we discuss how our basic update rule can be parameterized for different update policies, or learning methods. (shrink)
