Doctors have an ethical and legal duty to respect patient confidentiality. We consider the basis for this duty, looking particularly at the meaning and value of autonomy in health care. Enabling patients to decide how information about them is disclosed is an important element in autonomy and helps patients engage as active partners in their care.Good quality data is, however, essential for research, education, public health monitoring, and for many other activities essential to provision of health care. We discuss whether (...) it is necessary to choose between individual rights and the wider public interest and conclude that this should only rarely be necessary. The paper makes some recommendations on practical steps which could help ensure that good quality information is available for work which benefits society and the public health, while still enabling patients’ autonomy to be respected.

Although connectionism is advocated by its proponents as an alternative to the classical computational theory of mind, doubts persist about its _computational_ credentials. Our aim is to dispel these doubts by explaining how connectionist networks compute. We first develop a generic account of computation—no easy task, because computation, like almost every other foundational concept in cognitive science, has resisted canonical definition. We opt for a characterisation that does justice to the explanatory role of computation in cognitive science. Next we examine (...) what might be regarded as the “conventional” account of connectionist computation. We show why this account is inadequate and hence fosters the suspicion that connectionist networks aren’t genuinely computational. Lastly, we turn to the principal task of the paper: the development of a more robust portrait of connectionist computation. The basis of this portrait is an explanation of the representational capacities of connection weights, supported by an analysis of the weight configurations of a series of simulated neural networks.

Most models of corporate social responsibility revolve around the controversy as to whether business is a single dimensional entity of profit maximization or a multi-dimensional entity serving greater societal interests. Furthermore, the models are mostly descriptive in nature and are based on the experiences of western countries. There has been little attempt to develop a model that accounts for corporate social responsibility in diverse environments with differing socio-cultural and market settings. In this paper an attempt has been made to fill (...) this gap by developing a two-dimensional model of corporate social responsibility and empirically testing its validity in the context of two dissimilar cultures – Australia and Bangladesh. The two dimensions are the span of corporate responsibility and the range of outcomes of social commitments of businesses. The test results confirm the validity of the two-dimensional model in the two environments. The Factor analysis revealed two leading dimensions. Cluster analysis pointed to two distinctive clusters of managers in both Australia and Bangladesh, one consisting of managers with a broad contemporary concept of social responsibility, and the other with a limited narrow view. The paper concludes that corporate social responsibility is two-dimensional and universal in nature and that differing cultural and market settings in which managers operate may have little impact on the ethical perceptions of corporate managers.

THIS article concerning Mr. Marshall's open letter to Governor Smith does not pretend to be an answer. It suggests some philosophical considerations on the point at issue. The Editor.

_"The Essential Plotinus_ is a lifesaver. For many years my students in Greek and Roman Religion have depended on it to understand the transition from antiquity to the Middle Ages. The translation is crisp and clear, and the excerpts are just right for an introduction to Plotionus's many-layered view of the world and humankind’s place in it." --F. E. Romer, University of Arizona.

Hume is usually taken to have an evidentialist account of testimonial belief: one is justified in believing what someone says if one has empincal evidence that they have been reliable in the past. This account is impartialist: such evidence is required no matter who the person is, or what refotions she may have to you. I, however, argue that Hume has another account of testimony, one grounded in sympathy. This account is partialist, in that empincal evidence is not required in (...) order for one to be justified in believing some of the assertions of one's friends. (shrink)

Stobaeus records a placitum where Empedocles says that the world is destroyed by the domination in turn of Love and of Strife. The placitum makes perfectly good sense in the context of Empedocles' belief that Love and Strife produce, in turn, a non-cosmic state of total unity (Love) and of total separation (Strife). But for over two hundred years scholars have been unable to hear that simple message. Sturz (1805) emended the text so as to make it fit the non-cyclical (...) interpretation of Empedocles that he had taken over from the pages of Tiedemann (1791). When Diels included Stobaeus' text in his edition of Aetius, in the "Doxographi graeci" (1879), he failed to remove the emendation, although his own reconstruction of the chapter heading in Aetius made the emendation impossible. Twenty years later, Diels saw the light, and printed Stobaeus' placitum, unemended, in his "Poetarum philosophorum fragmenta" (1901) and in successive editions of his "Fragmente der Vorsokratiker" (from 1903 onwards). But Kranz resurrected the emendation in the "Nachträge" to his sixth edition of the "Fragmente der Vorsokratiker" (1951). The emended placitum is used again by Uvo Hölscher (1965) to support a non-cyclical interpretation of Empedocles and is repeated in the latest collection of the fragments and testimonia (Brad Inwood, 1992). Hölscher fails to appreciate that the text that he uses to support his reconstruction is merely Sturz's translation into Greek of the non-cyclical interpretation of Empedocles proposed by Tiedemann at the end of the eighteenth century.

While new generations of implantable brain computer interface devices are being developed, evidence in the literature about their impact on the patient experience is lagging. In this article, we address this knowledge gap by analysing data from the first-in-human clinical trial to study patients with implanted BCI advisory devices. We explored perceptions of self-change across six patients who volunteered to be implanted with artificially intelligent BCI devices. We used qualitative methodological tools grounded in phenomenology to conduct in-depth, semi-structured interviews. Results (...) show that, on the one hand, BCIs can positively increase a sense of the self and control; on the other hand, they can induce radical distress, feelings of loss of control, and a rupture of patient identity. We conclude by offering suggestions for the proactive creation of preparedness protocols specific to intelligent—predictive and advisory—BCI technologies essential to prevent potential iatrogenic harms.

ANALOGY has not just to do with the abstruse details and niceties of metaphysics but rather underlies the structure of all metaphysical thought. It is the heart of metaphysics. No system of metaphysics can discard it, without prejudice to the richness and variety of being. Without analogy there is elimination and over-simplification. Metaphysics is far from being a straightforward science; it is highly complex and its method and style of argument are not easy to master. Its field of inquiry is (...) wide. It is the task of the metaphysician to reduce the world of things to an intelligible unity. (shrink)

Prediction-based decisions, which are often made by utilizing the tools of machine learning, influence nearly all facets of modern life. Ethical concerns about this widespread practice have given rise to the field of fair machine learning and a number of fairness measures, mathematically precise definitions of fairness that purport to determine whether a given prediction-based decision system is fair. Following Reuben Binns (2017), we take ‘fairness’ in this context to be a placeholder for a variety of normative egalitarian considerations. We (...) explore a few fairness measures to suss out their egalitarian roots and evaluate them, both as formalizations of egalitarian ideas and as assertions of what fairness demands of predictive systems. We pay special attention to a recent and popular fairness measure, counterfactual fairness, which holds that a prediction about an individual is fair if it is the same in the actual world and any counterfactual world where the individual belongs to a different demographic group (cf. Kusner et al. (2018)). (shrink)

In this chapter I defend a novel view of the relationships among intention for the future, self-control, and co-operation. I argue that when an agent forms an intention for the future she comes to regard herself as criticizable if she does not act in accordance with her intention and as praiseworthy if she does. In forming intentions, then, agents acquire dispositions to have reflexive evaluative attitudes. In contexts where the agent has inclinations that run contrary to her unrescinded intention, these (...) evaluative attitudes help her to resist these inclinations. Intentions have, in other words, a built-in mechanism for self-control. I go on to argue that this mechanism can also function as a mechanism for co-operative behaviour. Sometimes a common species of co-operation just is the exercise of self-controlled behaviour in a social context. If this is on the right track, agents like us are not just equipped to formulate and abide by plans for the future, we are also thereby equipped for exercising self-control and participating in co-operative ventures.

One kind of successful communication involves the transmission of knowledge from speaker to hearer. Such testimonial knowledge transmission is usually seen as conforming to three widely held epistemological approaches: reliabilism, impartialism and evidentialism. First, a speaker must be a reliable testifier in order that she transmits knowledge, and reliability is cashed out in terms of her likelihood of speaking the truth. Second, if a certain speaker's testimony has sufficient epistemic weight to be believed by hearer1, then it should also be (...) believed by hearer2. Third, the normative constraint here is evidentially grounded: whether or not a hearer should believe a speaker depends on the evidence the hearer has that the speaker is telling the truth. I argue that there are cases of testimonial knowledge transmission that are incompatible with these three claims. This is when one accepts the testimony of an intimate friend. (shrink)

It is suggested that George Cotkin's essay is unpersuasive in its two central claims. Firstly, the evidence is not persuasive that there has been a discernible "moral turn" among historians in the last two decades; rather, it is argued that an engagement with morality has been fairly constant in historical scholarship since its ancient origins. Secondly, it is felt that Cotkin is evasive on whether he wishes historians merely to have opinions about the moralities of others in the past or (...) to be moral agents themselves; the first position is thought to be tenable, the latter probably not.

Niche construction is the process whereby organisms, through their activities and choices, modify their own and each other’s niches. By transforming natural-selection pressures, niche construction generates feedback in evolution at various different levels. Niche-constructing species play important ecological roles by creating habitats and resources used by other species and thereby affecting the flow of energy and matter through ecosystems—a process often referred to as “ecosystem engineering.” An important emphasis of niche construction theory (NCT) is that acquired characters play an evolutionary (...) role through transforming selective environments. This is particularly relevant to human evolution, where our species has engaged in extensive environmental modification through cultural practices. Humans can construct developmental environments that feed back to affect how individuals learn and develop and the diseases to which they are exposed. Here we provide an introduction to NCT and illustrate some of its more important implications for the human sciences. (shrink)

Teilhard’s cosmological speculation is a valuable basis for an environmental ethics that perceives individual natural objects as good in themselves and the world as good in itself. Teilhard perceives man as fundamentally part of a cosmic environmental whole that is greater than mankind taken individually or collectively. His holistic views on human biological and psychological and social evolution are, I argue, compatible with a biocentric environmental ethics. I discuss some similarities and differences with the views of the deep ecology movement. (...) I show that Teilhard’s hierarchical system is not humanistically oriented in a way that need be interpreted by Teilhardians as contrary to environmental well-being. I argue that Teilhard’s sympathies toward transportation technology, including the automobile, can be interpreted in his holistic manner. I conclude that Teilhard’s theocentric views are also a basis for supporting an environmental ethics which is both optimistic and not anthropocentric. (shrink)

O'Brien provides a critical assessment of Ernest Mandel's 1975 monograph Late Capitalism. In so doing, he offers a historical narrative that puts into question Mandel's framing of 'waves' of capitalist development as a process of capital accumulation that was dependent upon uneven development in the Third World. O'Brien starts by problematising Mandel's argument that an initial concentration of money, capital and bullion in the hands of Europeans explains combined and uneven development. He goes on to demonstrate that Mandel's (...) notion of imperialism as a necessary conduit for the flow of surplus capital from industrialising Europe does not stand up to the historical evidence. In fact, O'Brien maintains an alternative thesis, namely that these marginalised regions were insuffciently penetrated by European capital. (shrink)

There are different meanings associated with consequentialism and teleology. This causes confusion, and sometimes results in discussions based on misunderstandings rather than on substantial disagreements. To clarify this, we created a survey on the definitions of ‘consequentialism’ and ‘teleology’, which we sent to specialists in consequentialism. We broke down the different meanings of consequentialism and teleology into four component parts: Outcome-Dependence, Value-Dependence, Maximization, and Agent-Neutrality. Combining these components in different ways we distinguished six definitions, all of which are represented in (...) the philosophical literature. We asked the respondents which definition is best for consequentialism and for teleology. The most popular definition of consequentialism was the one which accepted value-dependence, but not maximization and agent-neutrality. We therefore recommend the use of this meaning to avoid misunderstandings. The results for teleology were more problematic, with several respondents claiming they never use the term, or indicating that it is confusing. (shrink)

In recent work Irigaray has continued to meditate on the myopic (we might say ‘monadic’) focus of the Western tradition when it comes to its failure to acknowledge sexuate difference. Irigaray has successfully diagnosed the patriarchally over-determined nature of that tradition masquerading behind a façade of objectivity and neutrality in ways that continue to open up interpretive and critical possibilities in terms of reading the canon today. In some of her work, Irigaray levels a powerful challenge against Heidegger’s conception of (...) Dasein and his point of entry into ‘phenomenological ontology’. Thus, Heidegger, the thinker that Irigaray, arguably, engages with most positively in some of her recent work is charged not just with the ‘exsanguination’ of his conception of Dasein, as it were, but with having neutered Dasein in a way that is all too characteristic of the monadic tendencies of the Western tradition and its enduring suppression of sexuate difference. Part of what we will examine in some depth in this section of the book is a blindspot in Heidegger’s account of Dasein which, for all of his insights concerning the social constitution of Dasein, leaves him open to some of the criticisms which Irigaray has successfully levelled against an entire tradition. As part of our efforts to tease these issues out in some detail, we will consider Derrida’s first Geschlecht essay where he looks to exonerate Heidegger from the charge of phallogocentrism (a charge he had levelled against him in a 1982 interview), along with more recent efforts to artificially cross-pollinate between Heidegger, Derrida and Irigaray. We will further examine the problematic ways that Heidegger looks to ‘neutralise’ Dasein in 1928 as well as his attempts in a series of 1930s texts to introduce a distinction between Dasein and the being of the human being. These attempts dovetail with a series of bizarre and illegitimate moves to exclude “whole peoples and races” from the domain of meaningful historical existence in the 1930s in particular. (shrink)

How is it that we think and refer in the first-person way? For most philosophers in the analytic tradition, the problem is essentially this: how two apparently conflicting kinds of properties can be reconciled and united as properties of the same entity. What is special about the first person has to be reconciled with what is ordinary about it. The range of responses reduces to four basic options. The orthodox view is optimistic: there really is a way of reconciling these (...) apparently contradictory properties as contained within the same thing. The heretical views are pessimistic and content to be so: there is no such way, and that is because there is simply nothing to reconcile – because there is really nothing special about what is in question; or there is really nothing ordinary about it; or there is really nothing ….

There are various forms of teleological thinking central to debates in the early modern and modern periods, debates in which David Hume (1711–1776) is a key figure. In the first section, we shall introduce three levels at which teleological considerations have been incorporated into philosophical accounts of man and nature, and sketch Hume’s criticisms of these approaches. In the second section, we turn to Hume’s non-teleological ‘science of man’. In the third section, we show how Hume has an account of (...) human flourishing that is not dependent on teleology. In the fourth section, we shall speculate as to the relation between Hume’s account of human nature and contemporary evolutionary accounts of morality and reasoning. (shrink)

This paper explores the character of emotion and its value in understanding ethical dilemmas in work organisations. Specifically, we examine the emotional labour of human resource professionals. Through in-depth interviews and diary study, we uncover the emotional and ethical struggles of HRPs as they search for the ‘right thing to do’ in situated interaction. Through the lens of emotion, we chart the process of how the very framing of what is deemed ‘right’ can move from the social to the moral (...) order and vice versa. Based on our findings, we contribute to understanding the linkages between emotional and ethical dilemmas, and how expectations of multiple ‘others’ at the individual, interpersonal and organisational level shape and constrain ethical choices.

Any creature that must move around in its environment to find nutrients and mates, in order to survive and reproduce, faces the problem of sensorimotor control. A solution to this problem requires an on-board control mechanism that can shape the creature’s behaviour so as to render it “appropriate” to the conditions that obtain. There are at least three ways in which such a control mechanism can work, and Nature has exploited them all. The first and most basic way is for (...) a creature to bump into the things in its environment, and then, depending on what has been encountered, seek to modify its behaviour accordingly. Such an approach is risky, however, since some things in the environment are distinctly unfriendly. A second and better way, therefore, is for a creature to exploit ambient forms of energy that carry information about the distal structure of the environment. This is an improvement on the first method since it enables the creature to respond to the surroundings without actually bumping into anything. Nonetheless, this second method also has its limitations, one of which is that the information conveyed by such ambient energy is often impoverished, ambiguous and intermittent. (shrink)

The behavioral sciences have flourished by studying how traditional and/or rational behavior has been governed throughout most of human history by relatively well-informed individual and social learning. In the online age, however, social phenomena can occur with unprecedented scale and unpredictability, and individuals have access to social connections never before possible. Similarly, behavioral scientists now have access to “big data” sets – those from Twitter and Facebook, for example – that did not exist a few years ago. Studies of human (...) dynamics based on these data sets are novel and exciting but, if not placed in context, can foster the misconception that mass-scale online behavior is all we need to understand, for example, how humans make decisions. To overcome that misconception, we draw on the field of discrete-choice theory to create a multiscale comparative “map” that, like a principal-components representation, captures the essence of decision making along two axes: aneast–westdimension that represents the degree to which an agent makes a decision independently versus one that is socially influenced, and anorth–south dimensionthat represents the degree to which there is transparency in the payoffs and risks associated with the decisions agents make. We divide the map into quadrants, each of which features a signature behavioral pattern. When taken together, the map and its signatures provide an easily understood empirical framework for evaluating how modern collective behavior may be changing in the digital age, including whether behavior is becoming more individualistic, as people seek out exactly what they want, or more social, as people become more inextricably linked, even “herdlike,” in their decision making. We believe the map will lead to many new testable hypotheses concerning human behavior as well as to similar applications throughout the social sciences. (shrink)

With my own introduction and epilogue, Towards a New Human Being gathers original essays by early career researchers and established academic figures in response to To Be Born, my most recent book. The contributors approach key issues of this book from their own scientific fields and perspectives – through calls for a different way of bringing up and educating children, the constitution of a new environmental and sociocultural milieu or the criticism of past metaphysics and the introduction of new themes (...) into the philosophical horizon. However, all the essays which compose the volume correspond to proposals for the advent of a new human being – so answering the subtitle of To Be Born: Genesis of a New Human Being. To Be Born thus acts as a background from which each author had the opportunity to develop and think in their own way. As such Towards a New Human Being is part of a longer-term undertaking in which I engaged together and in dialogue with more or less confirmed thinkers with a view to giving birth to a new human being and building a new world. –Luce Irigaray.

We argue that relating to myself as me provides, as such, a reason to care about myself: grasping that an event involves me, instead of another, makes it matter in a special way. Further, this self-concern is not simply a matter of seeing in myself some instrumental value for other ends. We use as our foil a recent skeptical challenge to this view offered in Setiya 2015. We think the case against self-concern is powered by unwarrantedly narrow construals of three (...) key notions. One is the notion of a first-personal way of relating to oneself. A narrow account of the first person in terms of special epistemic relations to oneself makes it easy to overlook a source of non-instrumental reasons of self-concern, located in the special relation a subject has to herself as agent. Two is the notion of what it is to be a reason. And, three, is the notion of self-concern itself. We show that the skeptical case rests in part on a slide towards neighbouring but distinct notions of egoism and selfishness. We also argue that Setiya’s notion of self-love, offered to capture the pre-theoretical intuition of self-concern, cannot do it justice. (shrink)

When cognitive scientists apply computational theory to the problem of phenomenal consciousness, as many of them have been doing recently, there are two fundamentally distinct approaches available. Either consciousness is to be explained in terms of the nature of the representational vehicles the brain deploys; or it is to be explained in terms of the computational processes defined over these vehicles. We call versions of these two approaches _vehicle_ and _process_ theories of consciousness, respectively. However, while there may be space (...) for vehicle theories of consciousness in cognitive science, they are relatively rare. This is because of the influence exerted, on the one hand, by a large body of research which purports to show that the explicit representation of information in the brain and conscious experience are _dissociable_, and on the other, by the _classical_ computational theory of mind – the theory that takes human cognition to be a species of symbol manipulation. But two recent developments in cognitive science combine to suggest that a reappraisal of this situation is in order. First, a number of theorists have recently been highly critical of the experimental methodologies employed in the dissociation studies – so critical, in fact, it’s no longer reasonable to assume that the dissociability of conscious experience and explicit representation has been adequately demonstrated. Second, classicism, as a theory of human cognition, is no longer as dominant in cognitive science as it once was. It now has a lively competitor in the form of _connectionism; _and connectionism, unlike classicism, does have the computational resources to support a robust vehicle theory of consciousness. In this paper we develop and defend this connectionist vehicle theory of consciousness. It takes the form of the following simple empirical hypothesis: _phenomenal experience consists in the explicit_ _representation of information in neurally realized PDP networks_.. (shrink)

This article offers an approach to advance the use of virtue ethics in the training of business managers and leaders, as well as in the education of business students. A thesis is that virtue ethics offers a valuable way to think about how we want to be and what we should strive to become qua businessperson, manager, and leader. The article provides a framework for thinking about virtue ethics in the context of business and leadership, with emphasis on building trust (...) in organizations. It includes a brief summary of Aristotelian virtue ethics, core concepts, and how they apply to management and leadership decision-making. The article concludes with a summary of an approach for teaching a virtue ethics module, which has evolved over the past 20 years. Included are exercises, a survey tool, and a business case as components of the module. The module has been used in corporate training, as well as graduate and undergraduate business education. It is hoped this approach will spur others to explore other ways to bring virtue ethics to business and business education. (shrink)

Archaeologists have proposed that behavioral knowledge of a tool can be conceptualized as a “recipe”—a unit of cultural transmission that combines the preparation of raw materials, construction, and use of the tool, and contingency plans for repair and maintenance. This parallels theories in cognitive psychology that behavioral knowledge is hierarchically structured—sequences of actions are divided into higher level, partially independent subunits. Here we use an agent-based simulation model to explore the costs and benefits of hierarchical learning relative to holistic learning, (...) where entire behavioral sequences are learned in an all-or-nothing fashion, and diffusionist learning, where actions are completely independent. Hierarchical learning is favored under the reasonable assumptions that learning is associated with some degree of both error and cost, and that behavior can be grouped into subunits that repeat in one or more tool recipes. These general predictions can be tested in the archaeological and ethnographic record. Recent advances in evolutionary developmental biology have revealed a number of parallels between the hierarchically structured, recipe-like organization of behavioral knowledge that we examine here and the manner in which biological organisms develop.
