The recent film District 9 raises several issues of significance to transhumanism. These issues include whether it is permissible to give a human being superhuman powers against his will, under what circumstances humans will be accepting of transhumans or posthumans, and what roles space colonization and extraterrestrial encounter may play in the future of humanity. Consideration of these issues deepens the viewing experience, and it can inform current decisions about transhumanism’s future as a cultural movement.

Diversity is an important ethical concept, but it is almost exclusively studied within two domains: biodiversity and diversity of sociological attributes such as race and gender. We provide a general study of the intrinsic value of diversity. We survey prior literature on the intrinsic value of biodiversity and sociological diversity in search of insights relevant to the intrinsic value of all types of diversity. We then present three thought experiments designed to clarify intuitions about the intrinsic value of small amounts (...) of diversity, large amounts of diversity, and diversity as compared to other intrinsic values. We find that many types of diversity are intrinsically valuable at both small and large amounts, but that diversity may be a weak intrinsic value in comparison to others. Noting that diversity can be defined in many ways, we propose that, for purposes of moral evaluation, diversity should be defined to include both a diversity of individual elements within a group and a diversity of the overall patterns or structures of the group. Some of our findings about the intrinsic value of diversity are tentative, indicating that moral intuitions about diversity are sometimes ambiguous and would benefit from further study. (shrink)

Are you in control of your own mind? Are you currently awake or dreaming? Does the narrative of perceived reality necessarily follow a linear, sequential path? To what extent do other people play roles in our perceived realities distinct from the environments in which we exist and interact? How deeply can we manipulate the mind of another person? What ethical issues does such manipulation raise? These questions, which have both deep philosophical and urgent practical significance, are all raised by the (...) recent film Inception . In this review, we develop these questions both as they appear in the film and as relate to the world we perceive as being real. Inception is a very dense film, raising more major ideas than we can discuss here. For example, we do not discuss the resilience of ideas within our minds or the power of the subconscious; the latter topic is among those covered in a separate review . In our review, we will give away much of the plot , but also offer topics for consideration that deepen the viewing experience. (shrink)

Purpose This paper aims to formalize long-term trajectories of human civilization as a scientific and ethical field of study. The long-term trajectory of human civilization can be defined as the path that human civilization takes during the entire future time period in which human civilization could continue to exist. -/- Design/methodology/approach This paper focuses on four types of trajectories: status quo trajectories, in which human civilization persists in a state broadly similar to its current state into the distant future; catastrophe (...) trajectories, in which one or more events cause significant harm to human civilization; technological transformation trajectories, in which radical technological breakthroughs put human civilization on a fundamentally different course; and astronomical trajectories, in which human civilization expands beyond its home planet and into the accessible portions of the cosmos. -/- Findings Status quo trajectories appear unlikely to persist into the distant future, especially in light of long-term astronomical processes. Several catastrophe, technological transformation and astronomical trajectories appear possible. -/- Originality/value Some current actions may be able to affect the long-term trajectory. Whether these actions should be pursued depends on a mix of empirical and ethical factors. For some ethical frameworks, these actions may be especially important to pursue. (shrink)

Since around 2012, there has been a ‘deep learning revolution’ in artificial intelligence (AI) that has brought AI to the forefront of many sectors of human activity. As new AI technology has sprea...

This paper discusses means for promoting artificial intelligence that is designed to be safe and beneficial for society. The promotion of beneficial AI is a social challenge because it seeks to motivate AI developers to choose beneficial AI designs. Currently, the AI field is focused mainly on building AIs that are more capable, with little regard to social impacts. Two types of measures are available for encouraging the AI field to shift more toward building beneficial AI. Extrinsic measures impose constraints (...) or incentives on AI researchers to induce them to pursue beneficial AI even if they do not want to. Intrinsic measures encourage AI researchers to want to pursue beneficial AI. Prior research focuses on extrinsic measures, but intrinsic measures are at least as important. Indeed, intrinsic factors can determine the success of extrinsic measures. Efforts to promote beneficial AI must consider intrinsic factors by studying the social psychology of AI research communities. (shrink)

A major approach to the ethics of artificial intelligence is to use social choice, in which the AI is designed to act according to the aggregate views of society. This is found in the AI ethics of “coherent extrapolated volition” and “bottom–up ethics”. This paper shows that the normative basis of AI social choice ethics is weak due to the fact that there is no one single aggregate ethical view of society. Instead, the design of social choice AI faces three (...) sets of decisions: standing, concerning whose ethics views are included; measurement, concerning how their views are identified; and aggregation, concerning how individual views are combined to a single view that will guide AI behavior. These decisions must be made up front in the initial AI design—designers cannot “let the AI figure it out”. Each set of decisions poses difficult ethical dilemmas with major consequences for AI behavior, with some decision options yielding pathological or even catastrophic results. Furthermore, non-social choice ethics face similar issues, such as whether to count future generations or the AI itself. These issues can be more important than the question of whether or not to use social choice ethics. Attention should focus on these issues, not on social choice. (shrink)

The National Science Foundation's Second Merit Criterion, or Broader Impacts Criterion , was introduced in 1997 as the result of an earlier Congressional movement to enhance the accountability and responsibility as well as the effectiveness of federally funded projects. We demonstrate that a robust understanding and appreciation of NSF BIC argues for a broader conception of research ethics in the sciences than is currently offered in Responsible Conduct of Research training. This essay advocates augmenting RCR education with training regarding broader (...) impacts. We demonstrate that enhancing research ethics training in this way provides a more comprehensive understanding of the ethics relevant to scientific research and prepares scientists to think not only in terms of responsibly conducted science, but also of the role of science in responding to identified social needs and in adhering to principles of social justice. As universities respond to the mandate from America COMPETES to “provide training and oversight in the responsible and ethical conduct of research”, we urge institutions to embrace a more adequate conception of research ethics, what we call the Ethical Dimensions of Scientific Research, that addresses the full range of ethical issues relevant to scientific inquiry, including ethical issues related to the broader impacts of scientific research and practice.

Atomically precise manufacturing (APM) is the assembly of materials with atomic precision. APM does not currently exist, and may not be feasible, but if it is feasible, then the societal impacts could be dramatic. This paper assesses the net societal impacts of APM across the full range of important APM sectors: general material wealth, environmental issues, military affairs, surveillance, artificial intelligence, and space travel. Positive effects were found for material wealth, the environment, military affairs (specifically nuclear disarmament), and space travel. (...) Negative effects were found for military affairs (specifically rogue actor violence and AI. The net effect for surveillance was ambiguous. The effects for the environment, military affairs, and AI appear to be the largest, with the environment perhaps being the largest of these, suggesting that APM would be net beneficial to society. However, these factors are not well quantified and no definitive conclusion can be made. One conclusion that can be reached is that if APM R&D is pursued, it should go hand-in-hand with effective governance strategies to increase the benefits and reduce the harms. (shrink)

This paper considers the question: In what ways can artificial intelligence assist with interdisciplinary research for addressing complex societal problems and advancing the social good? Problems such as environmental protection, public health, and emerging technology governance do not fit neatly within traditional academic disciplines and therefore require an interdisciplinary approach. However, interdisciplinary research poses large cognitive challenges for human researchers that go beyond the substantial challenges of narrow disciplinary research. The challenges include epistemic divides between disciplines, the massive bodies of (...) relevant literature, the peer review of work that integrates an eclectic mix of topics, and the transfer of interdisciplinary research insights from one problem to another. Artificial interdisciplinarity already helps with these challenges via search engines, recommendation engines, and automated content analysis. Future “strong artificial interdisciplinarity” based on human-level artificial general intelligence could excel at interdisciplinary research, but it may take a long time to develop and could pose major safety and ethical issues. Therefore, there is an important role for intermediate-term artificial interdisciplinarity systems that could make major contributions to addressing societal problems without the concerns associated with artificial general intelligence.

Artificial intelligence experts are currently divided into “presentist” and “futurist” factions that call for attention to near-term and long-term AI, respectively. This paper argues that the presentist–futurist dispute is not the best focus of attention. Instead, the paper proposes a reconciliation between the two factions based on a mutual interest in AI. The paper further proposes realignment to two new factions: an “intellectualist” faction that seeks to develop AI for intellectual reasons and a “societalist faction” that seeks to develop AI (...) for the benefit of society. The paper argues in favor of societalism and offers three means of concurrently addressing societal impacts from near-term and long-term AI: advancing societalist social norms, thereby increasing the portion of AI researchers who seek to benefit society; technical research on how to make any AI more beneficial to society; and policy to improve the societal benefits of all AI. In practice, it will often be advantageous to emphasize near-term AI due to the greater interest in near-term AI among AI and policy communities alike. However, presentist and futurist societalists alike can benefit from each others’ advocacy for attention to the societal impacts of AI. The reconciliation between the presentist and futurist factions can improve both near-term and long-term societal impacts of AI. (shrink)

In this essay we develop and argue for the adoption of a more comprehensive model of research ethics than is included within current conceptions of responsible conduct of research (RCR). We argue that our model, which we label the ethical dimensions of scientific research (EDSR), is a more comprehensive approach to encouraging ethically responsible scientific research compared to the currently typically adopted approach in RCR training. This essay focuses on developing a pedagogical approach that enables scientists to better understand and (...) appreciate one important component of this model, what we call intrinsic ethics . Intrinsic ethical issues arise when values and ethical assumptions are embedded within scientific findings and analytical methods. Through a close examination of a case study and its application in teaching, namely, evaluation of climate change integrated assessment models, this paper develops a method and case for including intrinsic ethics within research ethics training to provide scientists with a comprehensive understanding and appreciation of the critical role of values and ethical choices in the production of research outcomes.

To be intrinsically valuable means to be valuable for its own sake. Moral philosophy is often ethically anthropocentric, meaning that it locates intrinsic value within humans. This paper rejects ethical anthropocentrism and asks, in what ways might nonhumans be intrinsically valuable? The paper answers this question with a wide-ranging survey of theories of nonhuman intrinsic value. The survey includes both moral subjects and moral objects, and both natural and artificial nonhumans. Literatures from environmental ethics, philosophy of technology, philosophy of art, (...) moral psychology, and related fields are reviewed, and gaps in these literatures are identified. Although the gaps are significant and much work remains to be done, the survey nonetheless demonstrates that those who reject ethical anthropocentrism have considerable resources available to develop their moral views. Given the many very high-stakes issues involving both natural and artificial nonhumans, and the sensitivity of these issues to how nonhumans are intrinsically valued, this is a vital project to pursue.

Recent work in AI ethics often calls for AI to advance human values and interests. The concept of “AI for people” is one notable example. Though commendable in some respects, this work falls short by excluding the moral significance of nonhumans.

The paper outlines the case for more inclusive paradigms and presents implications for moral philosophy and (...) computer science work on AI ethics. (shrink)

Cost-benefit analysis (CBA) evaluates actions in terms of negative consequences (costs) and positive consequences (benefits). Though much has been said on CBA, little attention has been paid to the types of values held by costs and benefits. This paper introduces a simple typology of values in CBA and applies it to three forms of CBA: the common, money-based CBA, CBA based in social welfare, and CBA based in intrinsic value. The latter extends CBA beyond its usual anthropocentric domain. Adequate handling (...) of value typology in CBA avoids analytical mistakes and connects CBA to its consequentialist roots. (shrink)

In a recent editorial, Raymond Spier expresses skepticism over claims that climate change is driven by human actions and that humanity should act to avoid climate change. This paper responds to this skepticism as part of a broader review of the science and ethics of climate change. While much remains uncertain about the climate, research indicates that observed temperature increases are human-driven. Although opinions vary regarding what should be done, prominent arguments against action are based on dubious factual and ethical (...) positions. Thus, the skepticisms in the recent editorial are unwarranted. This does not diminish the general merits of skeptical intellectual inquiry. (shrink)

Seth Baum suggests that my claim that it is better never to come into existence “can readily be rejected not just out of reflexive distaste for the claim but also out of sound ethical reasoning”.

Where he does actually engage in my views, his response is effectively (...) merely to assert the opposite. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Prelude to the Special Issue of the Journal of Aesthetic Education on Children’s LiteratureEllen Handler Spitz, Guest Editor (bio)When Professor Pradeep A. Dhillon, editor of the Journal of Aesthetic Education, suggested to me one day that I might guest edit a special issue of the journal devoted to the topic of children’s literature, my initial reticence was toppled and my sense of resolve buoyed as I began to fantasize (...) with billowing excitement about just how this might be done. First, I dreamt up the image of guest editor as bountiful hostess—setting out delectable dishes in an elegantly appointed banquet before the readers of this journal. That metaphor faded, however, despite Maria Tatar’s eloquent reminder to us in these pages that gastronomy has frequently and salubriously been juxtaposed with reading. I could not help worrying (even though children vociferously protest the logic of this problem) that one cannot have one’s cake and eat it too. Therefore, switching to music, I began to imagine the editor as conductor of a highly select ensemble of musicians, all gifted with glorious well-seasoned voices. They might perform a concert (recorded for posterity, of course) of pieces aimed at an audience of those who care passionately about aesthetics, education, literature, and above all about children, and at those who, perhaps with tenderness, still recall their own childhood reading.But how to accomplish this in practical terms? Well, I reasoned, I would simply invite a group of distinguished senior scholars who, having achieved their reputations in related fields and having written on other subjects as well, have published highly significant works pertaining to children’s literature. Each person would contribute a composition in his or her own voice, and there would be complete freedom, carte blanche, no holds barred—the only constraint being page numbers. Would the results turn out to be harmony or cacophony? Well, I speculated, if each voice were finely tuned, resonant, and clear, whether treble or bass, forte or pianissimo, the outcome—although [End Page 1] unpredictable in terms of specifics—would, unquestionably, be musical. But that, dear reader, is ultimately for you to judge, for you have now heard precisely how this issue came into being and will, we hope, read on. Each author I asked responded to my call with alacrity and, in his or her original style and tone, made my task as conductor a perfect pleasure.We offer you a work in three parts. First, you will encounter two melodious and euphonious pieces, contributed respectively by Marina Warner (“Out of an Old Toy Chest”) and Maria Tatar (“From Bookworms to Enchanted Hunters: Why Children Read”). Here, the overarching themes of children’s play and make believe are set up, analyzed, and explored. Playing and reading are placed side by side, as well as reasons why children love to read and how they are variously exhorted, extolled, and even occasionally excoriated by adults for doing so.Our second movement consists of three apparently unrelated motifs, contributed in turn by Gareth Matthews (“Philosophical Adventures in the Lands of Oz and Ev”), Seth Lerer (“Style and the Mole: Domestic Aesthetics in The Wind in the Willows”), and myself (“Ethos in Steig’s and Sendak’s Picture Books: The Connected and the Lonely Child”). Actually, however, these essays are not unrelated, for each motif arises from a particular mode of interpretation grounded in turn in philosophy, in literary history and theory, and in psychology. The works considered are all by notable writers for children: L. Frank Baum, Kenneth Grahame, William Steig, and Maurice Sendak.For our grand finale, we offer two sonorous, seriously challenging contributions, one by Jack Zipes (“Why Fantasy Matters Too Much”) and the other by Eliza T. Dresang and Bowie Kotrla (“Radical Change Theory and Synergistic Reading for Digital Age Youth”). These works grapple with contemporary matters, with fantasy, with technology, and with “radical change” as these can be discerned in the literature, imagery, and general cultural lives of today’s and even, quite possibly, of tomorrow’s children. Gesturing toward the future even more strikingly, we conclude this work with a flourishing coda in the actual voice of a living child... (shrink)

Automated Influence is the use of Artificial Intelligence to collect, integrate, and analyse people’s data in order to deliver targeted interventions that shape their behaviour. We consider three central objections against Automated Influence, focusing on privacy, exploitation, and manipulation, showing in each case how a structural version of that objection has more purchase than its interactional counterpart. By rejecting the interactional focus of “AI Ethics” in favour of a more structural, political philosophy of AI, we show that the real problem (...) with Automated Influence is the crisis of legitimacy that it precipitates.

Previous research in Explainable Artificial Intelligence (XAI) suggests that a main aim of explainability approaches is to satisfy specific interests, goals, expectations, needs, and demands regarding artificial systems (we call these “stakeholders' desiderata”) in a variety of contexts. However, the literature on XAI is vast, spreads out across multiple largely disconnected disciplines, and it often remains unclear how explainability approaches are supposed to achieve the goal of satisfying stakeholders' desiderata. This paper discusses the main classes of stakeholders calling for explainability (...) of artificial systems and reviews their desiderata. We provide a model that explicitly spells out the main concepts and relations necessary to consider and investigate when evaluating, adjusting, choosing, and developing explainability approaches that aim to satisfy stakeholders' desiderata. This model can serve researchers from the variety of different disciplines involved in XAI as a common ground. It emphasizes where there is interdisciplinary potential in the evaluation and the development of explainability approaches. (shrink)

Both international and federal regulations exist to ensure that scientists perform research on human subjects in an environment free of coercion and in which the benefits of the research are commensurate with the risks involved. Ensuring that these conditions hold is difficult, and perhaps even more so when protocols include the issue of monetary compensation of research subjects. The morality of paying human research subjects has been hotly debated for over 40 years, and the grounds for this debate have ranged (...) from discussion of legal rights, economic rights, philosophical principles of vulnerability and altruism to bioethical concepts of consent, best-interest determination, and justice theory. However, the thought surrounding these issues has evolved over time, and the way we think about the role of the human research subject today is markedly different than the way we thought in the past. Society first thought of the research subject as an altruist, necessarily giving of his time to benefit society as a whole. As time progressed, many suggested that the subject should not need to sacrifice himself for research: if something goes wrong, someone should compensate the subject for injuries. The concept of redress evolved into a system in which subjects were offered money as an inducement to participate in research, sometimes merely to offset the monetary costs of participation, but sometimes even to mitigate the risks of the study. This article examines ethical and legal conversations regarding compensation from the 1960s through today, examining theories of the ethics of compensation both comparatively and critically. In conclusion, we put forward an ethical framework for treating paid research subjects, with an attempt to use this framework as a means of resolving some of the more difficult problems with paying human subjects in research.

On November 14, 1996, an in-depth report on the recruiting and testing practices of Lilly Pharmaceuticals appeared in the Wall Street Journal. Laurie Cohen reported that most pharmaceutical companies had difficulty recruiting healthy subjects to participate in testing of “untried and potentially dangerous” drugs. These companies often had to pay subjects up to $250 a day to ensure adequate enrollment, and some even gave referral bonuses to doctors who sent potential subjects their way. Cohen then exposed how Lilly was able (...) to keep costs down: by recruiting homeless alcoholics to serve as research guinea pigs. “In many ways,” Cohen reported, “the practice is mutually beneficial. For Lilly, it is efficient and limits the risk that subjects will sue if harmed by an experiment or divulge particulars of a drug.” And the subjects “get several weeks or months of free room and board, and in interviews they express voluble gratitude for what they often call easy money.”.

Recommender systems are artificial intelligence technologies, deployed by online platforms, that model our individual preferences and direct our attention to content we’re likely to engage with. As the digital world has become increasingly saturated with information, we’ve become ever more reliant on these tools to efficiently allocate our attention. And our reliance on algorithmic recommendation may, in turn, reshape us as moral agents. While recommender systems could in principle enhance our moral agency by enabling us to cut through the information (...) saturation of the internet and focus on things that matter, as they’re currently designed and implemented they’re apt to interfere with our ability to attend appropriately to morally relevant factors. In order to analyze the distinctive moral problems algorithmic recommendation poses, we develop a framework for the ethics of attention and an account of judicious attention allocation as a moral skill. We then discuss empirical evidence suggesting that attentional moral skill can be thwarted and undermined in various ways by algorithmic recommendation and related affordances of online platforms, as well as economic and technical considerations that support this concern. Finally, we consider how emerging technologies might overcome the problems we identify. (shrink)

Nearly as famous as his denial of the existence of matter is Berkeley's insistence that his philosophy is somehow a defense of commonsense. This is most often taken to mean that Berkeley thinks of his philosophy as supporting commonsense beliefs. However, the inadequacies of such views have persuaded some to disregard entirely Berkeley's claims about commonsense. Both readings are undesirable. Extant interpretations misunderstand the relationship between Berkeley's philosophy and commonsense. In this paper, I present a new account of how to (...) understand Berkeley's so-called defense of commonsense; it is not a defense-cum­-apology for commonsense beliefs, but a defensive attack against a skeptical threat. I then examine two rival accounts of the defense of commonsense and show how each fails to satisfy the criteria for a successful account. Finally, I briefly address the implications this view has for future scholarship. (shrink)

Specialists and primary care physicians play an integral role in treating the twin epidemics of pain and addiction. But inadequate access to specialists causes much of the treatment burden to fall on primary physicians. This article chronicles the differences between treatment contexts for both pain and addiction — in the specialty and primary care contexts — and derives a series of reforms that would empower primary care physicians and better leverage specialists.

Debates about the role of technology in sports officiating assume that technology would, _ceteris paribus_, improve accuracy over unassisted human officiating. While this is largely true, it also presents a false dilemma: that we can have accurately officiated sports or human officials, but not both. What this alleged dilemma ignores is that the criteria by which we measure accuracy are also up for revision. We _could_ have sports that are so defined as to be easily judged by human officials. A (...) case from the recent history of science provides an instructive example. I argue that _if_ we insist on human officials, we can still aim for maximal accuracy, though there will be tradeoffs. With compelling reasons to want accuracy in officiating, however, these tradeoffs effectively serve as a _reductio_ against the use of human officials unaided by technology. (shrink)

Following the warm reception given to The Idea of Education, a volume of papers in this same Rodopi Series, a second conference around similar themes was held at Oxford University and this book is the result.

Quoting the Chancellor of Paris University with regretting that “in the old days … lectures were more frequent … but now the time taken for lectures (...) is being spent in meeting and discussions” our keynote Frank McMahon made the profound observation that some of the issues around education have been with us for a surprisingly long time. Notwithstanding the longevity of some questions concerning education, this book details and examines contemporary educational practice and theory and as such it is a very important work. (shrink)
