There is currently little empirical information about attitudes towards cognitive enhancement - the use of pharmaceutical drugs to enhance normal brain functioning. It is claimed this behaviour most commonly occurs in students to aid studying. We undertook a qualitative assessment of attitudes towards cognitive enhancement by conducting 19 semi-structured interviews with Australian university students. Most students considered cognitive enhancement to be unacceptable, in part because they believed it to be unethical but there was a lack of consensus on whether it (...) was similar or different to steroid use in sport. There was support for awareness campaigns and monitoring of cognitive enhancement use of pharmaceutical drugs. An understanding of student attitudes towards cognitive enhancement is important in formulating future policy. (shrink)

Professional sports with high rates of concussion have become increasingly concerned about the long-term effects of multiple head injuries. In this context, return-to-play decisions about concussion generate considerable ethical tensions for sports physicians. Team doctors clearly have an obligation to the welfare of their patient (the injured athlete) but they also have an obligation to their employer (the team), whose primary interest is typically success through winning. At times, a team’s interest in winning may not accord with the welfare of (...) an injured player, particularly when it comes to decisions about returning to play after injury. Australia’s two most popular professional football codes—rugby league and Australian Rules football—have adopted guidelines that prohibit concussed players from continuing to play on the same day. I suggest that conflicts of interest between doctors, patients, and teams may present a substantial obstacle to the proper adherence of concussion guidelines. Concussion management guidelines implemented by a sport’s governing body do not necessarily remove or resolve conflicts of interest in the doctor–patient–team triad. The instigation of a concussion exclusion rule appears to add a fourth party to this triad (the National Rugby League or the Australian Football League). In some instances, when conflicts of interest among stakeholders are ignored or insufficiently managed, they may facilitate attempts at circumventing concussion management guidelines to the detriment of player welfare.

Debates about the ethical and social implications of research that aims to extend human longevity by intervening in the ageing process have paid little attention to the attitudes of members of the general public. In the absence of empirical evidence, conflicting assumptions have been made about likely public attitudes towards life-extension. In light of recent calls for greater public involvement in such discussions, this target article presents findings from focus groups and individual interviews which investigated whether members of the general (...) public identify ethical issues surrounding life-extension, and if so, what these ethical issues are? In this study, while some participants were concerned primarily with the likely personal consequences of life-extension, for others the question of whether or not to pursue interventions to extend longevity, and how they should be implemented, clearly raised important ethical issues, many of which have been prominent in debates among bioethicists.

This paper presents a novel view of the concept of cognitive enhancement by taking a population health perspective. We propose four main modifiable healthy lifestyle factors for optimal cognitive functioning across the population for which there is evidence of safety and efficacy. These include i) promoting adequate sleep, ii) increasing physical activity, iii) encouraging a healthy diet, including minimising consumption of stimulants, alcohol and other drugs including nicotine, iv) and promoting good mental health. We argue that it is not ethical (...) to promote or sanction the use of pharmaceutical drugs as putative cognitive enhancers without acknowledging the adverse effects on population cognitive health of failing to encourage the pursuit of healthy behaviours. We conclude with recommendations to increase the public health relevance of bioethical analyses of the cognitive enhancement debate. (shrink)

Neurodevices that collect neural (or brain activity) data have been characterised as having the ability to register the inner workings of human mentality. There are concerns that the proliferation of such devices in the consumer-directed realm may result in the mass processing and commercialisation of neural data (as has been the case with social media data) and even threaten the mental privacy of individuals. To prevent this, some argue that all raw neural data should be conceptualised and regulated as “medical (...) data” even if it is collected from consumer-directed devices in obviously non-clinical settings. In this paper, we argue that without a clearer formulation of what does and does not count as medical data, this approach might also uncritically enlarge the scope for medical influence and an unwarranted medicalisation of everyday aspects of mental life. Indeed, if we were to accept the position that all neural data is medical data because it offers insights into personally sensitive information (such a person’s thoughts, emotions, or intentions) then this could even unnecessarily expand the boundaries of medical data to other forms of data that otherwise seem to be non-clinical. If all brain data (neural activity data) is considered to be medical data even when collected from consumer-directed devices then we might unintentionally reduce meaningful distinctions between what is and what is not rightfully in the purview of medicine.

Head injuries are an inherent risk of participating in the major collision sports played in Australia. Protocols introduced by the governing bodies of these sports are ostensibly designed to improve player safety but do not prevent players suffering from repeated concussions. There is evidence that repeated traumatic brain injuries increase the risk of developing a number of long term problems but scientific and popular debates have largely focused on whether there is a causal link between concussion and chronic traumatic encephalopathy. (...) We argue that the governing bodies of collision sports played in Australia have used uncertainty about CTE to justify a “wait and see” approach instead of attempting to prevent repeated head injuries. This stance is difficult to defend when these governing bodies claim to give a high priority to protecting player welfare. (shrink)

The use of polyurethane swimsuits at the 2009 World Aquatics Championships resulted in world records being set for almost all swimming events. This paper explores the implications that the use of these performance-enhancing swimsuits had on fairness in relative and absolute outcomes in swimming. I claim that the use of ?super swimsuits? unfairly influenced relative outcomes within the competition because not all swimmers used, or had access to, the same types of swimsuit (some of which were clearly ?faster? than others). (...) Furthermore, I claim that the use of performance-enhancing swimsuits by current competitors unfairly influences inter-temporal relative outcomes. It is evident that competitors and coaches in elite swimming place great importance on making inter-temporal comparisons on the basis of absolute outcomes in the sport (as measured by a swimmer's race time). A ban on the use of super swimsuits may be justified in order to preserve the fairness of such inter-temporal comparisons, and records set using performance-enhancing swimsuits at the 2009 World Championships should be demarcated from others.

Concussion and Mild Traumatic Brain Injury affect millions of people worldwide. mTBI has been called the “signature injury” of the recent conflicts in Iraq and Afghanistan, affecting thousands of active duty service men and women, and veterans. Sport-related concussion represents a significant public health problem, with elite and professional athletes, and millions of youth and amateur athletes worldwide suffering concussions annually. These brain injuries have received scant attention from neuroethicists, and the focus of this special issue is on defining the (...) ethical considerations and developing and elucidating the neuroethical contributions to the discussion about concussion and mTBI.

The Concussion in Sport Group guidelines have successfully brought the attention of brain injuries to the global medical and sport research communities, and has significantly impacted brain injury-related practices and rules of international sport. Despite being the global repository of state-of-the-art science, diagnostic tools and guides to clinical practice, the ensuing consensus statements remain the object of ethical and sociocultural criticism. The purpose of this paper is to bring to bear a broad range of multidisciplinary challenges to the processes and (...) products of sport-related concussion movement. We identify lacunae in scientific research and clinical guidance in relation to age, disability, gender and race. We also identify, through multidisciplinary and interdisciplinary analysis, a range of ethical problems resulting from conflicts of interest, processes of attributing expertise in sport-related concussion, unjustifiably narrow methodological control and insufficient athlete engagement in research and policy development. We argue that the sport and exercise medicine community need to augment the existing research and practice foci to understand these problems more holistically and, in turn, provide guidance and recommendations that help sport clinicians better care for brain-injured athletes.

A timely and penetrating investigation, this book seeks to transform moral philosophy. In the face of continuing disagreement about which general moral principles are correct, there has been a resurgence of interest in the idea that correct moral judgements can be only about particular cases. This view--moral particularism --forecasts a revolution in ordinary moral practice that has until now consisted largely of appeals to general moral principles. Moral particularism also opposes the primary aim of most contemporary normative moral theory that (...) attempts to show that either one general principle, or a set of general principles, is superior to all its rivals.

This paper starts by characterising moral requirements and everyday thought. Then ways in which moral requirements shape everyday thought are identified, including the way internalised moral requirements prevent some possible actions from even being considered. The paper then explains that everyday moral thought might be structured by dispositions to which there are corresponding principles even if these principles do not usually appear in the conscious thoughts of agents while they are engaged in everyday moral decision-making. Nevertheless, especially when conflicts between (...) moral considerations arise, alternative possible resolutions are typically framed in terms of principles. The paper pushes on to discuss how everyday moral thought is pushed to consider principles, engage in moral theorising, and even consider abstract moral theories. (shrink)

The problem of the man who met death in Damascus appeared in the infancy of the theory of rational choice known as causal decision theory. A straightforward, unadorned version of causal decision theory is presented here and applied, along with Brian Skyrms’ deliberation dynamics, to Death in Damascus and similar problems. Decision instability is a fascinating topic, but not a source of difficulty for causal decision theory. Andy Egan’s purported counterexample to causal decision theory, Murder Lesion, is considered; a simple (...) response shows how Murder Lesion and similar examples fail to be counterexamples, and clarifies the use of the unadorned theory in problems of decision instability. I compare unadorned causal decision theory to previous treatments by Frank Arntzenius and by Jim Joyce, and recommend a well-founded heuristic that all three accounts can endorse. Whatever course deliberation takes, causal decision theory is consistently a good guide to rational action. (shrink)

Possible-worlds talk obscures, rather than clarifies, the debate about haecceitism. In this paper I distinguish haecceitism and anti-haecceitism from other doctrines that sometimes go under those names. Then I defend the claim that there are no non-tendentious definitions of ‘haecceitism’ and ‘anti-haecceitism’ using possible-worlds talk. That is, any definition of ‘haecceitism’ using possible-worlds talk depends, for its correctness, on a substantive theory of the nature of possible worlds. This explains why using possible-worlds talk when discussing haecceitism causes confusion: if the (...) parties to the discussion presuppose different theories of the nature of possible worlds, then they will mean different things by ‘haecceitism’.

One guide to an argument's significance is the number and variety of refutations it attracts. By this measure, the Dutch book argument has considerable importance.2 Of course this measure alone is not a sure guide to locating arguments deserving of our attention—if a decisive refutation has really been given, we are better off pursuing other topics. But the presence of many and varied counterarguments at least suggests that either the refutations are controversial, or that their target admits of more than (...) one interpretation, or both. The main point of this paper is to focus on a way of understanding the Dutch Book argument (DBA) that avoids many of the well-known criticisms, and to consider how it fares against an important criticism that still remains: the objection that the DBA presupposes value-independence of bets.

This paper looks at the debates between internalism and externalism in mind and epistemology. In each realm, internalists face what we call 'The Connection Problem', while externalists face what we call 'The Problem of Opacity'. We offer an integrated account of thought content and epistemic warrant that overcomes the problems. We then apply the framework to debates between internalists and externalists in metaethics.

The earliest philosophers thought deeply about ethical questions, but Aristotle founded ethics as a well-defined discipline. Brad Inwood focuses on the reception of Aristotelian ethical thought in the Hellenistic and Roman worlds and explores the thinker's influence on the philosophers who followed in his footsteps from 300 BCE to 200 CE.

Dutch Book arguments have been presented for static belief systems and for belief change by conditionalization. An argument is given here that a rule for belief change which under certain conditions violates probability kinematics will leave the agent open to a Dutch Book.

It is widely held that the influence of risk on rational decisions is not entirely explained by the shape of an agent’s utility curve. Buchak (Erkenntnis, 2013, Risk and rationality, Oxford University Press, Oxford, in press) presents an axiomatic decision theory, risk-weighted expected utility theory (REU), in which decision weights are the agent’s subjective probabilities modified by his risk-function r. REU is briefly described, and the global applicability of r is discussed. Rabin’s (Econometrica 68:1281–1292, 2000) calibration theorem strongly suggests that (...) plausible levels of risk aversion cannot be fully explained by concave utility functions; this provides motivation for REU and other theories. But applied to the synchronic preferences of an individual agent, Rabin’s result is not as problematic as it may first appear. Theories that treat outcomes as gains and losses (e.g. prospect theory and cumulative prospect theory) account for risk sensitivity in a way not available to REU. Reference points that mark the difference between gains and losses are subject to framing, many instances of which cannot be regarded as rational. However, rational decision theory may recognize the difference between gains and losses, without endorsing all ways of fixing the point of reference. In any event, REU is a very interesting theory.

The focus of this paper is to further a discussion of codes of ethics as institutionalized organizational structures that extend some form of legitimacy to organizations. The particular form of legitimacy is of critical importance to our analysis. After reviewing various theories of legitimacy, we analyze the literature on how legitimacy is derived from codes of ethics to discover which specific form of legitimacy is gained from their presence in organizations. We content analyze a sample of codes to consider the (...) question of whether a strategic, self-interested rationale lies behind the adoption of a code of ethics. We propose that the process of employing codes of ethics in this strategic manner has become, through isomorphism, an institutionalized practice that itself confers a cognitive form of legitimacy to the organization and further distances the codes from their moral foundation.

In recent years, political scientists have talked a great deal about the proper definition of their subject, and of how the ‘field’ of the political scientist is best distinguished from that of other social scientists. One proposal that is frequently made is that political science might quite properly be defined as the study of power, its forms, its sources, its distribution, its modes of exercise, its effects. The general justification for this proposal is, of course, that political activity itself appears (...) to be connected very intimately with power: it is often said that political activity is a struggle for power; that constitutions and other political institutions are methods of defining and regularising the distribution and the exercise of power, and so on. Since there seems to be some sense in which one can say that, within the wider area of social life, the political field is that which has some special connection with power, it may seem plausible then to suggest that the study of politics focusses upon the study of power.

I argue that van Fraassen’s selectionist explanation for the success of science is superior to the realists’ explanation. Whereas realists argue that our current theories are successful because they accurately reflect the structure of the world, the selectionist claims that our current theories are successful because unsuccessful theories have been eliminated. I argue that, unlike the explanation proposed by the realist, the selectionist explanation can also account for the failures of once successful theories and the fact that sometimes two competing (...) theories are both equally successful.

Understanding the social bases of what John Rawls meant by justice requires understanding a central part of Rawls’s professional life: his role as a teacher. As this essay shows, Rawls’s approach to teaching was not ancillary to his approach to heady philosophical issues like the justification of moral reasoning. Rather, there’s an ethic that runs through Rawls’s work, one focused on deliberation and consensus-seeking, and one whose strengths and weaknesses are easiest to see when you examine his teaching.

We review the various factors that limit adaptation by natural selection. Recent discussion of constraints on selection and, conversely, of the factors that enhance “evolvability”, have concentrated on the kinds of variation that can be produced. Here, we emphasise that adaptation depends on how the various evolutionary processes shape variation in populations. We survey the limits that population genetics places on adaptive evolution, and discuss the relationship between disparate literatures. BioEssays 22:1075–1084, 2000. © 2000 John Wiley & Sons, Inc.

Two criticisms of Dutch strategy arguments are discussed: One says that the arguments fail because agents who know the arguments can use that knowledge to avoid Dutch strategy vulnerability, even though they violate the norm in question. The second consists of cases alleged to be counterexamples to the norms that Dutch strategy arguments defend. The principle of Reflection and its Dutch strategy argument are discussed, but most attention is given to the rule of Conditionalization and to Jeffrey's rule for fallible (...) learning. I argue that the first criticism should be rejected, and that the second presents no counterexamples to the rationality of commitment to the rules. (shrink)

The primary aim of this paper is the presentation of a foundation for causal decision theory. This is worth doing because causal decision theory (CDT) is philosophically the most adequate rational decision theory now available. I will not defend that claim here by elaborate comparison of the theory with all its competitors, but by providing the foundation. This puts the theory on an equal footing with competitors for which foundations have already been given. It turns out that it will also (...) produce a reply to the most serious objections made so far against CDT and against the particular version of CDT I will defend. (shrink)
