Elephants show a rich social organization and display a number of unusual traits. In this paper, we analyse reports collected over a thirty-five year period, describing behaviour that has the potential to reveal signs of empathic understanding. These include coalition formation, the offering of protection and comfort to others, retrieving and 'babysitting' calves, aiding individuals that would otherwise have difficulty in moving, and removing foreign objects attached to others. These records demonstrate that an elephant is capable of diagnosing animacy and (...) goal directedness, and is able to understand the physical competence, emotional state and intentions of others, when they differ from its own. We argue that an empathic understanding of others is the simplest explanation of these abilities, and discuss reasons why elephants appear to show empathy more than other non-primate species.

Social media platforms offer convenient, instantaneous social sharing on a mass scale with tremendous impact on public perceptions, opinions, and behavior. There is a need to understand why information spreads including the human motivations, cognitive processes, and neural dynamics of large-scale sharing. This study introduces a novel approach for investigating the effect social media messaging and in-person discussion has on the inter-brain dynamics within small groups of participants. The psychophysiological impact of information campaigns and narrative messaging within a closed social (...) media environment was assessed using 24-channel wireless EEG. Data were acquired from three- or four-person groups while subjects debated contemporary social issues framed by four scenarios of varying controversy: investing in ethical vs. unethical corporations, selecting travel destination based on social awareness, determining verdict in a murder trial and the punishment of life in prison or death penalty, and decision to vaccinate. Pre-/post-scenario questionnaires assess the effects of the social media information. Inter-brain coherence between subject pairs on each social issue discussed by subjects was analyzed by concordance, agreement vs. disagreement, and by group unanimity, unanimous vs. not unanimous. Subject pairs that agreed on the social issues raised in the scenarios had significantly greater inter-brain coherence in gamma frequency range than disagreeing pairs over cortical regions known to be involved in social interactions. These effects were magnified when comparing groups where subject pairs were unanimous in their stance on the social issues for some but not all scenarios. While there was considerable overlap between scenarios in what EEG channels were significant, there was enough variability to indicate the possibility of scenario-specific effects on inter-brain coherence.

Background HIV prevention trials conducted among disadvantaged vulnerable at-risk populations in developing countries present unique ethical dilemmas. A key concern in bioethics is the validity of informed consent for trial participation obtained from research subjects in such settings. The purpose of this study was to investigate the effectiveness of a continuous informed consent process adopted during the MDP301 phase III vaginal microbicide trial in Mwanza, Tanzania. Methods A total of 1146 women at increased risk of HIV acquisition working as alcohol (...) and food vendors or in bars, restaurants, hotels and guesthouses have been recruited into the MDP301 phase III efficacy and safety trial in Mwanza. During preparations for the trial, participatory community research methods were used to develop a locally-appropriate pictorial flipchart in order to convey key messages about the trial to potential participants. Pre-recorded audio tapes were also developed to facilitate understanding and compliance with gel-use instructions. A comprehension checklist is administered by clinical staff to all participants at screening, enrolment, 12, 24, 40 and 50 week follow-up visits during the trial. To investigate women's perceptions and experiences of the trial, including how well participants internalize and retain key messages provided through a continuous informed consent process, a random sub-sample of 102 women were invited to participate in in-depth interviews conducted immediately after their 4, 24 and 52 week follow-up visits. Results 99 women completed interviews at 4-weeks, 83 at 24-weeks, and 74 at 52 weeks. In all interviews there was evidence of good comprehension and retention of key trial messages including that the gel is not currently know to be effective against HIV; that this is the key reason for conducting the trial; and that women should stop using gel in the event of pregnancy. Conclusions Providing information to trial participants in a focussed, locally-appropriate manner, using methods developed in consultation with the community, and within a continuous informed-consent framework resulted in high levels of comprehension and message retention in this setting. This approach may represent a model for researchers conducting HIV prevention trials among other vulnerable populations in resource-poor settings.

How should your opinion change in light of an epistemic peer's? We show that the pooling rule known as "upco" is the unique answer satisfying some natural desiderata. If your revised opinion will impact your other views by Jeffrey conditionalization, then upco is the only standard pooling rule that ensures the order in which peers are consulted makes no difference. Popular alternatives like linear pooling, geometric pooling, and harmonic pooling cannot boast the same. In fact, no alternative can that possesses (...) four minimal properties these proposals all share. (shrink)

We often learn the opinions of others without hearing the evidence on which they're based. The orthodox Bayesian response is to treat the reported opinion as evidence itself and update on it by conditionalizing. But sometimes this isn't feasible. In these situations, a simpler way of combining one's existing opinion with opinions reported by others would be useful, especially if it yields the same results as conditionalization. We will show that one method---upco, also known as multiplicative pooling---is specially suited to (...) this role when the opinions you wish to pool concern hypotheses about chances. The result has interesting consequences: it addresses the problem of disagreement between experts; and it sheds light on the social argument for the uniqueness thesis. (shrink)

Much of our information comes to us indirectly, in the form of conclusions others have drawn from evidence they gathered. When we hear these conclusions, how can we modify our own opinions so as to gain the benefit of their evidence? In this paper we study the method known as geometric pooling. We consider two arguments in its favour, raising several objections to one, and proposing an amendment to the other.

Disagreement is a common feature of a social world. For various reasons, however, we sometimes need to resolve a disagreement into a single set of opinions. This can be achieved by pooling the opinions of individuals that make up the group. This Element provides an opinionated survey on some ways of pooling opinions: linear pooling, multiplicative pooling (including geometric), and pooling through imprecise probabilities. While this Element gives significant attention to the axiomatic approach in evaluating pooling strategies, it also evaluates (...) them in terms of the epistemic and practical goals they might meet. In doing so, this Element connects opinion pooling to some philosophical problems in social epistemology and the philosophy of action, illuminating different perspectives one might take when figuring out how to pool opinions for a given purpose.

Models of collective deliberation often assume that the chief aim of a deliberative exchange is the sharing of information. In this paper, we argue that an equally important role of deliberation is to draw participants’ attention to pertinent questions, which can aid the assembly and processing of distributed information by drawing deliberators’ attention to new issues. The assumption of logical omniscience renders classical models of agents’ informational states unsuitable for modelling this role of deliberation. Building on recent insights from psychology, (...) linguistics and philosophy about the role of questions in speech and thought, we propose a different model in which beliefs are treated as answers directed at specific questions. Here, questions are formally represented as partitions of the space of possibilities and individuals’ information states as sets of questions and corresponding partial answers to them. The state of conversation is then characterised by individuals’ information together with the questions under discussion, which can be steered by various deliberative inputs. Using this model, deliberation is then shown to shape collective decisions in ways that classical models cannot capture, allowing for novel explanations of how group consensus is achieved. (shrink)

There are many reasons we might want to take the opinions of various individuals and pool them to give the opinions of the group they constitute. If all the individuals in the group have probabilistic opinions about the same propositions, there is a host of pooling functions we might deploy, such as linear or geometric pooling. However, there are also cases where different members of the group assign probabilities to different sets of propositions, which might overlap a lot, a little, (...) or not at all. There are far fewer proposals for how to proceed in these cases, and those there are have undesirable features. I begin by considering four proposals and arguing that they don't work. Then I'll describe my own proposal, which is intended to cover the situation in which we want to pool the individual opinions in order to ascribe an opinion to the group considered as an agent in its own right.

One of the characteristics of all somatic cells is a finite life span. Cells may proliferate until they reach a point after which, although they are metabolically active, they can no longer produce daughter cells. This observation is central to the clonal exhaustion hypothesis, a mechanism cited to explain age-associated immune dysfunction. In this hypothesis, repeated division of lymphocytes leads to a replicative limit, after which they enter the senescent phase but are not lost from the pool of T cells. (...) Advancing age would then be associated with an increase in the number of T cells that are unable to proliferate to a stimulus which induces a proliferative response in T cells from younger individuals. This hypothesis seems both logical and reasonable and is supported by data from both humans and mice with the demonstration of an age-related accumulation of senescent T cells in both species. However, there is an apparent paradox. The paradox arises because the onset of immunosenescence appears to be more closely linked to the life span of the animal rather than the life span of the lymphocyte.

Rae Langton and Caroline West argue that pornography silences women by presupposing misogynistic attitudes, such as that women enjoy being raped. More precisely, they claim that a somewhat infamous pictorial, ‘Dirty Pool’, makes such presuppositions, and that it is typical in this respect. I argue for four claims. (1) There are empirical reasons to doubt that women are silenced in the way that Langton and West claim they are. (2) There is no evidence that very much pornography makes the sorts (...) of presuppositions that Langton and West's explanation of silencing requires it to make. (3) Even ‘Dirty Pool’, for all its other problems, does not make such presuppositions. (4) Langton and West misread ‘Dirty Pool’ because they do not take proper account of the fact that pornography often traffics in sexual fantasy. The broader lesson is that we need to read pornography more sensitively if we are to understand its capacity to shape socio‐sexual norms (for good or for ill). (shrink)

In studies of multi-agent interaction, especially in game theory, the notion of equilibrium often plays a prominent role. A typical scenario for the belief merging problem is one in which several agents pool their beliefs together to form a consistent "group" picture of the world. The aim of this paper is to define and study new notions of equilibria in belief merging. To do so, we assume the agents arrive at consistency via the use of a social belief removal function, (...) in which each agent, using his own individual removal function, removes some belief from his stock of beliefs. We examine several notions of equilibria in this setting, assuming a general framework for individual belief removal due to Booth et al. We look at their inter-relations as well as prove their existence or otherwise. We also show how our equilibria can be seen as a generalisation of the idea of taking maximal consistent subsets of agents. (shrink)

This paper seeks to show the relationship between psychiatry and capitalism and how psychiatry is being commodified to bring it into the capitalist circuit of accumulation. Capitalism extols the virtues of individualism, work, and consumption and offers a rationalization for unlimited acquisition that blunts ethical challenge, themes that have a parallel in psychiatric thought and practice. In its incessant search for profit, capitalism is always seeking to enlarge its markets by, for example, commodifying various activities of daily life. Psychiatry creates (...) and enlarges its market by expanding its diagnostic system: an increasing number of difficult or troubling experiences are labeled psychiatric, thus creating an ever-larger pool of potential customers, or patients, for psychiatric services. The relationship between capitalism and psychiatry has been obscured, in part, because psychiatry is a profession with different ideals than business. With the arrival of corporate capitalism in the health care arena, however, the boundaries between professionalism and business are eroding in favor of the latter. Psychiatrists and other physicians are now discovering that their professional activities are vulnerable to the same relentless logic of profitability that any activity in a capitalist society is vulnerable to.

Decision-making typically requires judgments about causal relations: we need to know the causal effects of our actions and the causal relevance of various environmental factors. We investigate how several individuals' causal judgments can be aggregated into collective causal judgments. First, we consider the aggregation of causal judgments via the aggregation of probabilistic judgments, and identify the limitations of this approach. We then explore the possibility of aggregating causal judgments independently of probabilistic ones. Formally, we introduce the problem of causal-network aggregation. (...) Finally, we revisit the aggregation of probabilistic judgments when this is constrained by prior aggregation of qualitative causal judgments. (shrink)

At a meeting of the American Society for Value Inquiry in Chicago last spring, and again at a conference on biomedical ethics last fall in London, Ontario, David J. Roy, Head of the Institute for Medical Humanities, University of Montreal, described a developing situation in the biomedical technologies about which he and many of his colleagues in the profession share an enormous apprehension. The biomedical sciences have in their possession, in development, and on the drawing boards a technology that has (...) the potential of enabling us to alter much of what has to date been seen as fundamental givens and fixed points of the human situation, from the forms of human reproduction, through the frequency of distribution of various human characteristics, to those very characteristics themselves. His question , in the form of a plea, was this: it is becoming desperately urgent that scientists and technologists in these fields be given guidance about what they are doing; the sense is that what can be done ranges far beyond what should be done, and that the technological imperative (do what technology makes possible) and the epistemological imperative (find a use for what we know) are so strong that, in the absence of a normative consensus of what it is to be human, these sciences and technologies may well have a transforming impact upon a society that is not prepared to control them. When it becomes possible to eliminate the traditional and biological form of human reproduction, with the development of in vitro fertilization and the artificial placenta, shall we? When it becomes possible to eliminate deleterious genes from the human gene pool (or to limit their occurrence to the level of chance mutation), shall we? When it becomes possible to enable parents to select in advance characteristics of their offspring, from sex to hair and eye color, and perhaps even to influence the polygenic determinate and determinable characteristics of race, stature, aggressiveness, intelligence and talent, to the point that we can influence the distribution of propensities and abilities in the population to fit more closely the manpower needs of our society, shall we? Shall we breed astronauts, musicians.. (shrink)

This paper takes a unique approach to framing the political obligation social media companies like Twitter and Facebook have in a democratic society by casting the public sphere as a common-pool resource. Over the last decade or so much of our civic discourse has moved to social media platforms such as Facebook and Twitter. This paper argues that just as citizens have an obligation to one another, social media companies have an obligation to promote agonistic forms of civic, political discourse (...) through their algorithms. This algorithmic obligation that social media companies have must be reconciled with social media companies’ formulation of their fiduciary shareholder obligations. We posit that a commons based view of social media discourse allows these companies to make both a democratic health and fiduciary interest argument. (shrink)

This study examines the impact of corporate social orientation on organizational attractiveness as it relates to information about an organization’s handling of diversity issues. Using Aupperle’s notion of corporate social orientation (CSO), we examined how CSO affects perceived attractiveness of organizations’ emphasizing affirmative action versus diversity management policies in their recruitment literature. Respondents to a survey of 343 college students reported a more favorable assessment of affirmative action programs than diversity management programs. In addition, the legal dimension of CSO was (...) positively related to affirmative action programs. Also investigated were the underlying dimensions of organizational attractiveness—intentions and beliefs—these were more positive for affirmative action programs than for diversity management. A discussion of practical implications for organizations seeking to recruit from a diverse applicant pool and suggestions for future research is offered. (shrink)

Dawkins’ concept of the meme pool, essentially equivalent to Popper’s World 3, is considered as an expression in modern terms for what Averroes knew as the ‘active intellect’, an immortal entity feeding into, or even creating, the ‘passive intellect’ of consciousness. A means is thus provided for reconciling a materialist Darwinian view of the universe with a conception of non-personal immortality. The meme pool/active intellect correspondence provides a strong basis for regarding science as a communal enterprise producing enrichment of the (...) meme pool and expansion of consciousness, and emphasizes the virtues of memetic conservation in relation to vanishing cultures.

The paper provides a presentation and motivation of the concept of non-empirical theory confirmation. Non-empirical theory confirmation is argued to play an important role in the scientific process that has not been adequately acknowledged so far. Its formalization within a Bayesian framework demonstrates that non-empirical confirmation does have the essential structural characteristics of theory confirmation.

Scientific thought is characterized in general as methodical and rational. I would like to present here an opposing view which treats science as a non-systematic activity, where serendipity, tinkering and imitation, rather than so-called rational thought, characterizes it. All these kinds of acts, which are considered to be a-rational, are related to an evolutionary view of science. I will deal here with a version of evolutionary epistemology as applied to science, integrated with the concept uf "meme". Richard Dawkins, who (...) coined the term "meme", treats memes as units of information which propagate in the meme-pool by leaping from brain to brain. The way that memes replicate is through imitation. Examples for this phenomenon in science are illustrated by some historical cases. In particular, I will deal with the evolution of theories of "internal symmetries" in particle physics. Memetics is the counterpart of genetics in the cultural arena. In its application to science, it deals with the manner memes/ideas spread in scientific communities. (shrink)

Beliefs come in different strengths. What are the norms that govern these strengths of belief? Let an agent's belief function at a particular time be the function that assigns, to each of the propositions about which she has an opinion, the strength of her belief in that proposition at that time. Traditionally, philosophers have claimed that an agent's belief function at any time ought to be a probability function (Probabilism), and that she ought to update her belief function upon obtaining (...) new evidence by conditionalizing on that evidence (Conditionalization). Until recently, the central arguments for these claims have been pragmatic. But these putative justifications fail to identify what is epistemically irrational about violating Probabilism or Conditionalization. A new approach, which I will call epistemic utility theory, attempts to remedy this. It treats beliefs as epistemic acts; and it appeals to the notion of an epistemic utility function, which measures of how epistemically valuable a particular belief function is for a particular way the world might be. It then formulates fundamental epistemic norms that are analogous to the fundamental practical norms that underlie decision theory. I survey the results obtained so far in this young research project, and present a sustained critique of certain assumptions that have been made by a number of philosophers working in this area.

This paper begins with a discussion of two features of the everyday task environment. First, the everyday task environment is designed, and an important part of the design is the provision of explicit information to guide the individual in the adaptation of his activity. Second, some task environments are semi‐permanent. These two features of the task environment reveal some important characteristics in the psychology of the individual. When novelty occurs, expansion in the range of behavior of the individual is guided (...) by a process of internalization of information provided in the task environment by another. Because of the semi‐permanence of home task environments, there is pay‐off in organizing behavior in terms of the particulars of those environments. The body of this paper examines these ideas from the perspective of FLOABN. FLOABN is a computational cognitive model of an individual acquiring skill at using household and office devices. (shrink)

This volume guides the reader through a detailed examination of the text to an understanding of Locke’s political ideas in relation to his writings on philosophy, education, religion and economics and the influence these ideas had upon eighteenth-century political theorists. The author shows how Locke carefully constructed his political perspective as a defence of the principles of natural rights, constitutional government and popular resistance. He offers an original interpretation of the Two Treatises…, emphasizing the specific ways in which Locke’s political (...) purposes in writing the work influence his discussion of such concepts as the state of nature, property, consent and tyranny. The author discusses the historical and biographical context of the work and demonstrates how eighteenth century political thinkers developed or rejected aspects of Locke’s political theory and summarizes important recent studies of Locke’s work.

This paper highlights the significance of sensory studies and psychophysical investigations of the relations between psychic and physical phenomena for our understanding of the development of the physics discipline, by examining aspects of research on sense perception, physiology, esthetics, and psychology in the work of Gustav Theodor Fechner, Hermann von Helmholtz, Wilhelm Wundt, and Ernst Mach between 1860 and 1871. It complements previous approaches oriented around research on vision, Fechner’s psychophysics, or the founding of experimental psychology, by charting Mach’s engagement (...) with psychophysical experiments in particular. Examining Mach’s study of the senses and esthetics, his changing attitudes toward the mechanical worldview and atomism, and his articulation of comparative understandings of sensual, geometrical, and physical spaces helps set Mach’s emerging epistemological views in the context of his teaching and research. Mach complemented an analytic strategy focused on parallel psychic and physical dimensions of sensation, with a synthetic comparative approach – building analogies between the retina, the individual, and social life, and moving between abstract and sensual spaces. An examination of the broadly based critique that Mach articulated in his 1871 lecture on the conservation of work shows how his historical approach helped Mach cast what he now saw as a narrowly limiting emphasis on mechanics as a phase yet to be overcome.

Global culture, forms of governance, economic and development models have become drastically dissociated from biological and cultural diversity and their interrelationships. Global society is exposed to globally homogeneously governed life habits that tend to build globally homogeneous technological and urban habitats in the heterogeneous regions of the planet. Concurrently, these globally homogeneous habitats reinforce globally homogeneous life habits. These feedbacks between globalized habits and habitats generate processes of biocultural homogenization, which represents an overlooked dimension of global changes in the Anthropocene. (...) Biocultural homogenization is both driver and product of complex and pervasive losses of biological and cultural diversity. We maintain that it is technically necessary and ethically imperative to reverse these losses. Toward this aim, we present the “3Hs” conceptual framework of the biocultural ethic, which values the vital links among the diversity of life habits of distinct co-in-habitants that share a common habitat. We offer this philosophical framework as a heuristic model for: better understanding multidimensional and multi-scale processes involved in global changes; designing policies that integrate biocultural diversity into ethical, political, and environmental dimensions of the contemporary technological world; and orienting decision-making processes that can better assess the consequences that development policies might have for the conservation or degradation of habitats, life habits, and welfare of co-inhabitants. In this way, the 3Hs “philosophical lens” of the biocultural ethic can contribute to re-orienting global society toward sustainable forms of co-inhabitation amidst the rapidly changing socio-environmental scenarios of the Anthropocene.
