The main purpose of the paper is to investigate the relevance and significance of the concept of common good in contemporary society. First, I make a brief historical remark about the philosophical concept of common good. I will argue that the concept is rooted in the ancient Greek philosophical understanding of society, namely as polis, whereby human being is thought to have an end that is not merely individual but also collective. I then discuss how societies have significantly changed over (...) the years and how the current global order resembles the situation during the time of Alexander the Great, whose vision it was to establish a cosmopolis, literally a global city. In the end, I consider whether the notion of common good in itself has lost its relevance in the face of the manifold social changes. I bring my discussion to a close with a note on the universality and naturality of the common good of humankind. (shrink)

Pleasure has always been an important issue in morality. And although ethical systems tend to focus the discussion on human action, this agreeable sentiment has remained a recurrent question in moral philosophy. In this paper, I go back to Aristotle’s treatment of pleasure in his writings, particularly in the Nicomachean Ethics. I will argue that the distinction he draws between bodily pleasures and those of the mind represents an important point not only in understanding eudaimonia but also in situating the (...) very nature of ethical debates today. I will try to show how Aristotle’s distinction among pleasure matches up with his differentiation between energeia and kinésis as well as with the distinction between praxis and poiésis, and how these differentiations have enabled Aristotle toevade the pitfall of hedonism.

With the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), global researchers were confronted with major challenges. The German National Pandemic Cohort Network (NAPKON) was launched in fall 2020 to effectively leverage resources and bundle research activities in the fight against the coronavirus disease 2019 (COVID-19) pandemic. We analyzed the setup phase of NAPKON as an example for multicenter studies in Germany, highlighting challenges and optimization potential in connecting 59 university and nonuniversity study sites. We examined the ethics application (...) process of 121 ethics submissions considering durations, annotations, and outcomes. Study site activation and recruitment processes were investigated and related to the incidence of SARS-CoV-2 infections. For all initial ethics applications, the median time to a positive ethics vote was less than two weeks and 30 of these study sites (65%) joined NAPKON within less than three weeks each. Electronic instead of postal ethics submission (9.5 days (Q1: 5.75, Q3: 17) vs. 14 days (Q1: 11, Q3: 26), p value = 0.01) and adoption of the primary ethics vote significantly accelerated the ethics application process. Each study center enrolled a median of 37 patients during the 14-month observation period, with large differences depending on the health sector. We found a positive correlation between recruitment performance and COVID-19 incidence as well as hospitalization incidence. Our analysis highlighted the challenges and opportunities of the federated system in Germany. Digital ethics application tools, adoption of a primary ethics vote and standardized formal requirements lead to harmonized and thus faster study initiation processes during a pandemic. (shrink)

This piece presents the work of academics and architects in a collaborative venture. It provides an architectural design and a series of statements towards the hypothetical creation of an unconventional city centre in the Chinese city of Shenzhen. The idea is to create a linear university that would run the 20-kilometer length of the Shenzhen Strip: the 20K university. The contributors outline, in the diversity of their idioms, a complex spatial condition fundamental to life, and demonstrate new relationships between knowledge (...) and the city. The design of the proposed ‘open university space’ responds to two simultaneous and interrelated challenges: that posed to architecture, and that posed to science. The university would embody the meeting of these at the intersection of the urban infrastructure and the knowledge infrastructure. The purpose is thus also to develop the notion of knowledge, embodied in institutions, as urban infrastructure. (shrink)

Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

Objectives To analyse the perspective of clinical research stakeholders concerning post-trial access to study medication. Methods Questionnaires and informed consents were sent through e-mail to 599 ethics committee (EC) members, 290 clinical investigators (HIV/AIDS and Diabetes) and 53 sponsors in Brazil. Investigators were also asked to submit the questionnaire to their research patients. Two reminders were sent to participants. Results The response rate was 21%, 20% and 45% in EC, investigators and sponsors’ groups, respectively. 54 patients answered the questionnaire through (...) their doctors. The least informative item in the consent form was how to obtain the study medication after trial. If a benefit were demonstrated in the study, 60% of research participants and 35% of EC answered that all patients should continue receiving study medication after trial; 43% of investigators believed the medication should be given to participants, and 40% to subjects who participated and benefited from treatment. For 50% of the sponsors, study medication should be assured to participants who had benefited from treatment. The majority of responders answered that medication should be provided free by sponsors; investigators and sponsors believed the medication should be kept until available in the public health sector; EC members said that the patient should keep the benefit; patients answered that benefits should be assured for life. Conclusions Due to the study limitations, the results cannot be generalised; however, the data can contribute to discussion of this complex topic through analysing the views of stakeholders in clinical research in Brazil.

Several variants of Lewis's Best System Account of Lawhood have been proposed that avoid its commitment to perfectly natural properties. There has been little discussion of the relative merits of these proposals, and little discussion of how one might extend this strategy to provide natural property-free variants of Lewis's other accounts, such as his accounts of duplication, intrinsicality, causation, counterfactuals, and reference. We undertake these projects in this paper. We begin by providing a framework for classifying and assessing the variants (...) of the Best System Account. We then evaluate these proposals, and identify the most promising candidates. We go on to develop a proposal for systematically modifying Lewis's other accounts so that they, too, avoid commitment to perfectly natural properties. We conclude by briefly considering a different route one might take to developing natural property-free versions of Lewis's other accounts, drawing on recent work by Williams. (shrink)

CONSCIOUSNESS AND THE BRAIN SELF-REGULATION PARADOX The relationship of consciousness to biology has intrigued mankind thoroughout recorded history. However, little progress has been made not only in understanding these issues but also in raising fundamental questions central to the problem. As Davidson and Davidson note in their introduction, William James suggested, almost a century ago in his Principles of Psychology, that the brain was the organ of mind and be havior. James went so far as to suggest that the remainder (...) of the Principles was but a "footnote" to this central thesis. This volume brings together diverse biobehavioral scientists who are addressing the various aspects of the mindlbrainlbodylbehavior issue. Although some of the authors have previously published together in other volumes, by and large the particular combination of authors and topics selected by the editors makes this volume unique and timely. Unlike the Consciousness and Self-Regulation series (Schwartz & Shapiro, 1976, 1978), also published by Plenum, this volume is devoted entirely to a psychobiological approach to consciousness. Although readers will differ in their interest in specific chapters, the well-rounded investigator who is concerned with the psychobiology of consciousness will want to become intimately acquainted with all the views presented in this volume. As noted by the individual contributors, the topic of this volume stimulates fundamental questions which, on the surface, may appear trivial, yet, on further reflection, turn out to have deep significance.

Luck permeates our lives, and this raises a number of pressing questions: What is luck? When we attribute luck to people, circumstances, or events, what are we attributing? Do we have any obligations to mitigate the harms done to people who are less fortunate? And to what extent is deserving praise or blame a ected by good or bad luck? Although acquiring a true belief by an uneducated guess involves a kind of luck that precludes knowledge, does all luck undermine (...) knowledge? And how accurate are our luck attributions anyway? The academic literature has seen growing, interdisciplinary interest in luck, and this volume brings together and explains the most important areas of this research. It consists of 39 newly commissioned chapters, written by an internationally acclaimed team of philosophers and psychologists, for a readership of students and researchers. Its coverage is divided into six sections: (i) The History of Luck, (ii) The Nature of Luck, (iii) Moral Luck, (iv) Epistemic Luck, (v) The Psychology of Luck, and (vi) Future Research. The chapters in these sections cover a wide range of topics, from the problem of moral luck, to anti-luck epistemology, to the relationship between luck attributions and cognitive biases, to meta-questions regarding the nature of luck itself, to a range of other theoretical and empirical questions currently being investigated by ethicists, epistemologists, and psychologists. By bringing this research together, the Handbook serves as both a touchstone for understanding the relevant issues and a first port of call for future philosophical and psychological research on luck.

Modern zoos strive to educate visitors about zoo animals and their wild counterparts’ conservation needs while fostering appreciation for wildlife in general. This research review examines how zoos influence those who visit them. Much of the research to-date examines zoo visitors’ behaviors and perceptions in relation to specific exhibits, animals and/or programs. In general, visitors have more positive perceptions and behaviors about zoos, their animals and conservation initiatives the more they interact with animals, naturalistic exhibits, and zoo programming/staff. Furthermore, zoo (...) visitors are receptive to conservation messaging and initiatives at zoos, and are more likely to participate in on-site conservation opportunities as opposed to after their visits. The research also suggests that repeat visitors are even more inclined to seek out conservation efforts compared to those visiting zoos for the first time. While current research suggests that repeat-visitors are more likely to engage in conservation efforts, little is known about causal factors related to such findings, and almost no research exists to-date comparing the conservation efforts of visitors vs. non-visitors. This latter comparison will likely play a greater role in future zoo visitor research, since it poses one of the most important metrics for evaluating the specific effects visiting a zoo can have on people engaging in conservation efforts in general.

In 1991, Jones developed an issue-contingent model of ethical decision making in which moral intensity is posited to affect the four stages of Rest's 1986 model. Jones claimed that moral intensity, which is "the extent of issue-related moral imperative in a situation", consists of six characteristics: magnitude of consequences, social consensus, probability of effect, temporal immediacy, proximity, and concentration of effect. This article reports the findings of two studies that analyzed the factor structure of moral intensity, operationalized by a 12-item (...) Perceived Moral Intensity Scale adapted from the work of Sing-hapakdi et al. [1996, Journal of Business Research, 36, 245-255] and Frey [2000, Journal of Business Ethics, 26, 181-195]. The two items that were purported to measure CE were dropped due to their inability to effectively tap into the characteristic proposed by Jones. Factor analyses of the remaining 10 items supported a 3-factor structure, with the MC, PE, and TI items loading on the first factor, the PX items loading on the second factor, and the SC items loading on the third factor. These factors were labeled: Probable Magnitude of Consequences, Proximity, and Social Consensus. The authors conclude that moral intensity consists of three characteristics, rather than the six posited by Jones. (shrink)

The model of clinical ethics consultation (CEC) defended in the ASBH Core Competencies report has gained significant traction among scholars and healthcare providers. On this model, the aim of CEC is to facilitate deliberative reflection and thereby resolve conflicts and clarify value uncertainty by invoking and pursuing a process of consensus building. It is central to the model that the facilitated consensus falls within a range of allowable options, defined by societal values: prevailing legal requirements, widely endorsed organizational policies, and (...) professional standards of practice and codes of conduct. Moreover, the model stipulates that ethics consultants must refrain from giving substantive recommendations regarding how parties to a moral disagreement in the clinic should evaluate their options. We argue that this model of CEC is incomplete, because it wrongly assumes that what counts as the proper set of allowable options among which the parties are to deliberate will itself always be clearly discernible. We illustrate this problem with a recent case on which one of us consulted—a neonate born with trisomy 18 (T18). We try to show that law, policy, and standards of practice reveal no clear answer to the question posed by the case: namely, whether forgoing gastrostomy tube feedings for a baby with T18 is allowable. We suggest there may be other kinds of cases in which it may simply be unsettled whether a given choice falls within the set of allowable options within which consensus is to be facilitated. What should an ethicist do when confronting such unsettled cases? We agree with the facilitation model that an ethicist should remain neutral among the allowable options, when it is clear what the allowable options are. But, in unsettled cases, the role of a consultant should be expanded to include a process of moral inquiry into what the allowable options should be. We end by raising the issue of whether this means an ethicist should share his or her own conclusions or views about the allowability of a given clinical option. (shrink)

Every day, in many situations, we use expressions which seem only vaguely to provide us with information. The weather forecaster tells us that "some showers are likely in Northern regions during the night", a statement which is vague with respect to number of showers, location, and time. Yet such messages are informative, and often it is not possible for the producer of the message to be more precise. A tutor tells his students that "only a few students fail their exams (...) outright". This does not give a precise incidence. Yet it might be equally misleading to do so. For example, to say that 12% failed outright last year says nothing about other years, while to say an average of 8% over the last five years says nothing about variability. We argue that a precise, numerical statement can be sometimes more misleading in reality than a vague statement. Many researchers in psychology have attempted to capture the meaning of quantities by relating them to scales of quantity. The book explores this idea in detail and shows with original studies how these expressions also serve to control attention and to convey information about the expectations held by those involved in the communication. The book works towards a psychological theory of the meaning of quantifiers and similarly vague terms. New links are drawn between formal theories of quantification and psychological experimentation.

Psychologists and philosophers have recently been exploring whether the mechanisms which underlie the acquisition of ‘theory of mind’ (ToM) are best charac- terized as cognitive modules or as developing theories. In this paper, we attempt to clarify what a modular account of ToM entails, and why it is an attractive type of explanation. Intuitions and arguments in this debate often turn on the role of develop- ment: traditional research on ToM focuses on various developmental sequences, whereas cognitive modules are thought (...) to be static and ‘anti-developmental’. We suggest that this mistaken view relies on an overly limited notion of modularity, and we explore how ToM might be grounded in a cognitive module and yet still afford development. Modules must ‘come on-line’, and even fully developed modules may still develop internally, based on their constrained input. We make these points con- crete by focusing on a recent proposal to capture the development of ToM in a module via parameterization. (shrink)

The sociobiology of bacteria, largely unappreciated and ignored by the microbiology research community two decades ago is now a major research area, catalyzed to a significant degree by studies of communication and cooperative behavior among the myxobacteria and in quorum sensing (QS) and biofilm formation by pseudomonads and other microbes. Recently, the topic of multicellular cooperative behaviors among bacteria has been increasingly considered in the context of evolutionary biology. Here we discuss the significance of two recent studies1,2 of the phenomenon (...) of “cheating” mutants and their exploitation of cooperating microbial populations of Pseudomonas aeruginosa.

Experiments may contribute to understanding the basic processes of cultural evolution. We drew features from previous laboratory research with small groups in which traditions arose during several generations. Groups of four participants chose by consensus between solving anagrams printed on red cards and on blue cards. Payoffs for the choices differed. After 12 min, the participant who had been in the experiment the longest was removed and replaced with a naı¨ve person. These replacements, each of which marked the end of (...) a generation, continued for 10 – 15 generations, at which time the day’s session ended. Time-out duration, which determined whether the group earned more by choosing red or blue, and which was fixed for a day’s session, was varied across three conditions to equal 1, 2, or 3 min. The groups developed choice traditions that tended toward maximizing earnings. The stronger the dependence between choice and earnings, the stronger was the tradition. Once a choice tradition evolved, groups passed it on by instructing newcomers, using some combination of accurate information, mythology, and coercion. Among verbal traditions, frequency of mythology varied directly with strength of the choice tradition. These methods may be applied to a variety of research questions. D 2004 Elsevier Inc.

How did meat emerge to become such an important feature in Western society? In both popular and academic literatures, biophysical and political-economic factors are often cited as the reason for meat’s preeminent status. In this paper, we perform a comprehensive investigation of these claims by reviewing the available evidence on the political-economic and biophysical features of meat over the long arc of Western history. We specifically focus on nine critical epochs: the Paleolithic, early to late Neolithic, antiquity, ancient Israel and (...) early Christian societies, medieval Europe, early modern Europe, colonial America, the American frontier, and the modern industrial era. We find that except under conditions of environmental scarcity, the meaning and value of meat cannot be attributed to intrinsic biophysical value or to the political-economic actors who materially benefit from it. Rather, meat’s status reflects the myriad cultural contexts in which it is socially constructed in people’s everyday lives, particularly with respect to religious, gender, communal, racial, national, and class identity. By deconstructing the normalized/naturalized materialist assumptions circling around meat consumption, this paper clears a space for a more nuanced appreciation of the role that culture has played in the legitimation of meat, and by extension, the possibility of change.

Behavioral immune system describes psychological mechanisms that detect cues to infectious pathogens in the immediate environment, trigger disease-relevant responses and facilitate behavioral avoidance/escape. BIS activation elicits a perceived vulnerability to disease which can result in conformity with social norms. However, a response to superficial cues can result in aversive responses to people that pose no actual threat, leading to an aversion to unfamiliar others, and likelihood of prejudice. Pathogen-neutralizing behaviors, therefore, have implications for social interaction as well as illness behaviors (...) and responses to health communications. In this study, we investigate how PVD influences conformity, attitudes to other people and to lockdown regulations through the lens of the Reinforcement Sensitivity Theory. RST describes personality in terms of biologically-driven approach and avoidance motivations which support personal goals. Participants from the United Kingdom public completed an RST personality questionnaire and then read either coronavirus morbidity-mortality statistics and current United Kingdom government lifestyle regulations, just the regulations, or no information at all. They all completed the Perceived Vulnerability to Disease scale to assess BIS-relevant Germ Aversion and Perceived Infectability, followed by questions measuring social conformity, warmth toward others and attitudes toward lockdown measures. Significantly lower PVD scores were observed in the no-information condition, with the other conditions showing no difference. In terms of RST, approach behaviors related to goal-drive persistence work alongside fear in explaining conformity to social norms. Reward related approach behaviors partially explained warmth toward others, indicating that social rewards gained through interaction continue to be strong drivers of behavior. We found no role for RST traits in attitudes toward lockdown. Overall, coronavirus-related behavior is not driven purely by fear, but also by social and/or protection goals regulated by approach motivation. This study presents new insights into public perceptions of coronavirus and government regulated lifestyle restrictions, helping to explain social behaviors in terms of biologically driven mechanisms. Such understanding is vital if we are to successfully motivate public behavior to constrain spread of the virus. (shrink)

Game theory has a prominent role in evolutionary biology, in particular in the ecological study of various phenomena ranging from conflict behaviour to altruism to signalling and beyond. The two central methodological tools in biological game theory are the concepts of Nash equilibrium and evolutionarily stable strategy. While both were inspired by a dynamic conception of evolution, these concepts are essentially static—they only show that a population is uninvadable, but not that a population is likely to evolve. In this article, (...) we argue that a static methodology can lead to misleading views about dynamic evolutionary processes. We advocate, instead, a more pluralistic methodology, which includes both static and dynamic game theoretic tools. Such an approach provides a more complete picture of the evolution of strategic behaviour. 1 Introduction2 The Equilibrium Methodology3 Common Interest Signalling3.1 Lewis’s signalling game3.2 Static analysis3.3 Dynamic analysis4 The Sir Philip Sidney Game4.1 Static analysis4.2 Other equilibria4.3 Dynamic analysis5 Related Literature6 Static and Dynamic Approaches.

The answer to philosophical questions will often depend on the position one takes regarding the fact-value problem. It is, therefore, not surprising that, in the tradition of western philosophy, the past 200 years or so record an animated discussion of it. In the present collection the debate is continued by representatives of various "schools" in contemporary western thought. A number of philosophers from non-western cultures, too, enter into it. The contributions do not all reflect on the same theme, nor do (...) they use the same approach. Essays written by philosophers sympathetic to the analytical tradition are followed by reflections on the part of those inspired by phe nomenology. A third group of contributions is by non-western thinkers, who are more likely to approach the problem in terms of culture. Their engage ment with the issue clearly shows, among other things, that it is almost exclusively in the western tradition that the fact-value distinction is often understood as an outright dichotomy. The occasion for the publication of this collection is Dr. Cornelis Anthonie van Peursen's retirement as Professor of Philosophy. This year he leaves the Free University, Amsterdam; until 1982 he was professor at the University of Leyden as well. In the Netherlands and beyond he has become known for his concern with constructive comparison of diverging philosophical trends and the cross-cultural fertilization of thought. Characteristic of his career are his efforts to render the results of academic philosophizing understand able to a broader audience. (shrink)

We study the handicap principle in terms of the Sir Philip Sidney game. The handicap principle asserts that cost is required to allow for honest signalling in the face of conflicts of interest. We show that the significance of the handicap principle can be challenged from two new directions. Firstly, both the costly signalling equilibrium and certain states of no communication are stable under the replicator dynamics ; however, the latter states are more likely in cases where honest signalling should (...) apply. Secondly, we prove the existence and stability of polymorphisms where players mix between being honest and being deceptive and where signalling costs can be very low. Neither the polymorphisms nor the states of no communication are evolutionarily stable, but they turn out to be more important for standard evolutionary dynamics than the costly signalling equilibrium.
