May lethal autonomous weapons systems—‘killer robots ’—be used in war? The majority of writers argue against their use, and those who have argued in favour have done so on a consequentialist basis. We defend the moral permissibility of killer robots, but on the basis of the non-aggregative structure of right assumed by Just War theory. This is necessary because the most important argument against killer robots, the responsibility trilemma proposed by Rob Sparrow, makes the same assumptions. We show that (...) the crucial moral question is not one of responsibility. Rather, it is whether the technology can satisfy the requirements of fairness in the re-distribution of risk. Not only is this possible in principle, but some killer robots will actually satisfy these requirements. An implication of our argument is that there is a public responsibility to regulate killer robots ’ design and manufacture. (shrink)

Achieving space situational awareness requires, at a minimum, the identification, characterization, and tracking of space objects. Leveraging the resultant space object data for purposes such as hostile threat assessment, object identification, and conjunction assessment presents major challenges. This is in part because in characterizing space objects we reference a variety of identifiers, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, operational processes, operational statuses, and so forth, which tend to be defined in highly heterogeneous and sometimes inconsistent (...) ways. The Space Domain Ontologies are designed to provide a consensus-based realist framework for formulating such characterizations in a way that is both consistent and computable. Space object data are aligned with classes and relations in a suite of ontologies built around the existing Space Object Ontology. They are stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space situational awareness and the needs of spacecraft operators and analysts. This paper provides an overview of the Space Domain Ontologies and their development and use. It presents the motivation for and advantages of the Space Domain Ontologies, including the benefits they provide for enhancing and maintaining long-term space situational awareness. (shrink)

The argument of Julian Savulescu’s 2001 paper, “Procreative Beneficence: Why We Should Select the Best Children” is flawed in a number of respects. Savulescu confuses reasons with obligations and equivocates between the claim that parents have some reason to want the best for their children and the more radical claim that they are morally obligated to attempt to produce the best child possible. Savulescu offers a prima facie implausible account of parental obligation, as even the best parents typically fail to (...) do everything they think would be best for their children let alone everything that is in fact best for their children. The profound philosophical difficulties which beset the attempt to formulate a plausible account of the best human life constitute a further independent reason to resile from Savulescu’s conclusion. Savulescu’s argument also requires parents to become complicit with racist and homophobic oppression, which is yet another reason to reject it. Removing the equivocation from Savulescu’s argument allows us to see that the assertion of an obligation to choose the “best child” has much more in common with the “old” eugenics than Savulescu acknowledges.

The fact that real-world decisions made by artificial intelligences (AI) are often ethically loaded has led a number of authorities to advocate the development of “moral machines”. I argue that the project of building “ethics” “into” machines presupposes a flawed understanding of the nature of ethics. Drawing on the work of the Australian philosopher, Raimond Gaita, I argue that ethical dilemmas are problems for particular people and not (just) problems for everyone who faces a similar situation. Moreover, the force of (...) an ethical claim depends in part on the life history of the person who is making it. For both these reasons, machines could at best be engineered to provide a shallow simulacrum of ethics, which would have limited utility in confronting the ethical and policy dilemmas associated with AI.

A number of philosophers working in applied ethics and bioethics are now earnestly debating the ethics of what they term “moral bioenhancement.” I argue that the society-wide program of biological manipulations required to achieve the purported goals of moral bioenhancement would necessarily implicate the state in a controversial moral perfectionism. Moreover, the prospect of being able to reliably identify some people as, by biological constitution, significantly and consistently more moral than others would seem to pose a profound challenge to egalitarian (...) social and political ideals. Even if moral bioenhancement should ultimately prove to be impossible, there is a chance that a bogus science of bioenhancement would lead to arbitrary inequalities in access to political power or facilitate the unjust rule of authoritarians; in the meantime, the debate about the ethics of moral bioenhancement risks reinvigorating dangerous ideas about the extent of natural inequality in the possession of the moral faculties.

This essay constitutes an attempt to probe the very idea of a saying/showing distinction of the kind that Wittgenstein advances in the Tractatus—to say what such a distinction consists in, to say what philosophical work it has to do, and to say how we might be justified in drawing such a distinction. Towards the end of the essay the discussion is related to Wittgenstein’s later work. It is argued that we can profitably see this work in such a way that (...) a saying/showing distinction arises there too. In particular, in the final sub-section of the essay, it is suggested that we can see in Wittgenstein’s later work an inducement to say what we are shown. (shrink)

This paper uses the fictional case of the ‘Babel fish’ to explore and illustrate the issues involved in the controversy about the use of cochlear implants in prelinguistically deaf children. Analysis of this controversy suggests that the development of genetic tests for deafness poses a serious threat to the continued flourishing of Deaf culture. I argue that the relationships between Deaf and hearing cultures that are revealed and constructed in debates about genetic testing are themselves deserving of ethical evaluation. Making (...) good policy about genetic testing for deafness will require addressing questions in political philosophy and anthropology about the value of culture and also thinking hard about what sorts of experiences and achievements make a human life worthwhile.

There is a current debate about the grammar of intention: do I intend to φ, or that I φ? The equivalent question in Aristotle relates especially to choice. I argue that, in the context of practical reasoning, choice, as also wish, has as its object an act. I then explore the role that this plays within his account of the relation of thought to action. In particular, I discuss the relation of deliberation to the practical syllogism, and the thesis that (...) the conclusion of the second is an action. (shrink)

It is often claimed that the development of nanotechnology will constitute a “technological revolution” with profound social, economic, and political consequences. The full implications of this claim can best be understood by imagining a scenario in which a political revolutionary made all the same claims that are commonly made by enthusiasts for nanotechnology. I argue that most people would be outraged to learn that the members of an unelected group were planning to radically reshape society in this fashion. I survey (...) a number of arguments that might be used to block this analogy and argue that none of them justify drawing a sharp distinction between social change due to technology and change due to other political causes. Two things follow for discussions of the social impacts of nanotechnology. First, we need to reconsider the appropriateness of the language of technological revolution when talking about nanotechnology. The likely impacts of nanotechnology may be less dramatic than is often claimed. Second, if we do decide that the language of revolution is the appropriate one to use when talking about nanotechnology then we should acknowledge that any such revolution should be delayed until the public has had a chance to make a democratic decision about whether they wish their lives to be transformed in this way.

That technologies may raise ethical issues is now widely recognised. The ‘responsible innovation’ literature – as well as, to a lesser extent, the applied ethics and bioethics literature – has responded to the need for ethical reflection on technologies by developing a number of tools and approaches to facilitate such reflection. Some of these instruments consist of lists of questions that people are encouraged to ask about technologies – a methodology known as the ‘Socratic approach’. However, to date, these instruments (...) have often not adequately acknowledged various political impacts of technologies, which are, I suggest, essential to a proper account of the ethical issues they raise. New technologies can make some people richer and some people poorer, empower some and disempower others, have dramatic implications for relationships between different social groups and impact on social understandings and experiences that are central to the lives, and narratives, of denizens of technological societies. The distinctive contribution of this paper, then, is to offer a revised and updated version of the Socratic approach that highlights the political, as well as the more traditionally ethical, issues raised by the development of new technologies.

What does Artificial Intelligence (AI) have to contribute to health care? And what should we be looking out for if we are worried about its risks? In this paper we offer a survey, and initial evaluation, of hopes and fears about the applications of artificial intelligence in medicine. AI clearly has enormous potential as a research tool, in genomics and public health especially, as well as a diagnostic aid. It’s also highly likely to impact on the organisational and business practices (...) of healthcare systems in ways that are perhaps under-appreciated. Enthusiasts for AI have held out the prospect that it will free physicians up to spend more time attending to what really matters to them and their patients. We will argue that this claim depends upon implausible assumptions about the institutional and economic imperatives operating in contemporary healthcare settings. We will also highlight important concerns about privacy, surveillance, and bias in big data, as well as the risks of over trust in machines, the challenges of transparency, the deskilling of healthcare practitioners, the way AI reframes healthcare, and the implications of AI for the distribution of power in healthcare institutions. We will suggest that two questions, in particular, are deserving of further attention from philosophers and bioethicists. What does care look like when one is dealing with data as much as people? And, what weight should we give to the advice of machines in our own deliberations about medical decisions? (shrink)

This chapter describes the potential far‐reaching consequences of contemplative higher education for the fields of science and medicine.

How do artifacts get their functions? It is typically thought that an artifact’s function depends on its maker’s intentions. This chapter argues that this common understanding is fatally flawed. Nor can artifact function be understood in terms of current uses or capacities. Instead, it proposes that we understand artifact function on the etiological model that Ruth Millikan and others have proposed for the biological realm. This model offers a robustly normative conception of function, but it does so naturalistically by employing (...) our best scientific theories, in particular natural selection. To help make this case, it proposes “living artifacts” (organisms designed for human purposes through artificial selection) as a bridge between the artifactual and the biological realms. (shrink)

When doubts were first raised about the veracity of the dramatic advances in stem cell research announced by Professor Hwang Woo-Suk, a significant minority response was to question the qualifications of journalists to investigate the matter. In this paper I examine the contemporary relationships between science, scientists, the public, and the media. In the modern context the progress of science often relies on the media to mobilise public support for research and also for the purpose of communication within the scientific (...) community. As a result, attempts to counterpose "science" and "the media" should be treated with some caution. I argue that because of the essential role played by ethics in good science, journalists may in fact sometimes be well placed to investigate scientists. At the conclusion of my paper I draw out some of the implications of my analysis for the ethics of investigative journalism directed towards scientific research. (shrink)

In this essay, we aim to provide an overview of the political and philosophical issues pertaining to asexuality. The first section, “What Is Asexuality?,” offers an account of asexuality. The second section, “Asexuality as a Unique Sexual Orientation,” argues that asexuality should be understood as a unique sexual orientation. The third section, “Asexuality and Oppression,” discusses the various forms of oppression facing asexual persons today. The fourth section, “The Goods of Asexuality,” articulates some goods that asexuality brings to human lives, (...) and we do this with an eye toward conceiving of asexuality as something other than a mere deficit.

[A. W. Moore] Criteria of ineffability are presented which, it is claimed, preclude the possibility of truths that are ineffable, but not the possibility of other things that are ineffable—not even the possibility of other things that are non-trivially ineffable. Specifically, they do not preclude the possibility of states of understanding that are ineffable. This, it is argued, allows for a reappraisal of the dispute between those who adopt a traditional reading of Wittgenstein’s Tractatus and those who adopt the new (...) reading recently championed by Cora Diamond, James Conant, and others. By maintaining that what the nonsense in the Tractatus is supposed to convey is ineffable understanding, rather than ineffable truth, we can do considerable justice to each of these readings. We can also do considerable justice to the Tractatus. /// [Peter Sullivan] Moore proposes to cut between 'traditional' and 'new' approaches to the Tractatus, suggesting that Wittgenstein's intention is to convey, through the knowing use of nonsense, ineffable understanding. I argue, first, that there is indeed room for a proposal of Moore's general kind. Secondly, though, I question whether Moore's actual proposal is not more in tune with Wittgenstein's later thought than with the attitude of the Tractatus. (shrink)

Wrong beliefs, known by some as ‘alternative facts’, have proliferated lately in important areas of human life, including social, political, and public health domains. This can be and has been damaging. This brief article proposes an epistemological category classification of these wrong beliefs, with the following mappings: a) ‘No-Information’ marked by willful blindness produces ‘Empty Beliefs’; b) ‘Mis-Information’ yields ‘Mis(taken) Beliefs’; and c) ‘Dis-Information’ predicated on blatant distortions produces ‘Dis(torted) Beliefs’. This simple classification system, is perhaps epistemologically satisfying, and moreover (...) could have positive policy implications. (shrink)

How, if at all, are we to distinguish between the works that we call ‘art’ and those that we call ‘pornography’? This question gets a grip because from classical Greek vases and the frescoes of Pompeii to Renaissance mythological painting and sculpture to Modernist prints, the European artistic tradition is chock-full of art that looks a lot like pornography. In this paper I propose a way of thinking about the distinction that is grounded in art historical considerations regarding the function (...) of erotic images in 16 th -century Italy. This exploration suggests that the root of the erotic art/pornography distinction was—at least in this context—class: in particular, the need for a special category of unsanctioned illicit images arose at the very time when print culture was beginning to threaten elite privilege. What made an erotic representation exceed the boundaries of acceptability, I suggest, was not its extreme libidinosity but, rather, its widespread availability and, thereby, its threat to one of the mechanisms of sustaining class privilege.

In the last two decades, the term “quality-of-life” has become popular in medicine and health care. There are, however, important differences in the meaning and the use of the term. The message of all quality-of-life talk is that medicine and health care are not valuable in themselves. They are valuable to the extent that they contribute to the quality of life of patients. The ultimate aims of medicine and health care are not health or prolongation of life as such, but (...) preservation or improvement of the quality of life. The primary aims of medicine and health care, such as the prolongation of life, can – but need not always – come into conflict with the ultimate ones: medical treatments do not always benefit a patient. In this article I will, first, summarize the results of my explorations of the use and the meaning of the term “quality-of-life.” The use and the meaning of the term turn out to depend on the contexts of medical decisionmaking in which it is used. I will show that there are at least three different concepts of quality-of-life. Second, I will argue that the different concepts of quality-of-life are not unrelated. They point to different components of and/or conditions for happiness. Third, I will analyze the relation between the three concepts of qualityof-life, health and happiness. (shrink)

This essay involves exploration of certain repercussions of Bernard Williams’ view that there is, in Wittgenstein’s later work, a transcendental idealism akin to that found in the Tractatus—sharing with it the feature that it cannot be satisfactorily stated. It is argued that, if Williams is right, then Wittgenstein’s later work precludes a philosophically substantial theory of meaning; for such a theory would force us to try to state the idealism. In a postscript written for the reprint of the essay, reasons (...) are given for thinking that Williams is not right: Wittgenstein’s later work actually helps us to repudiate as ill-conceived all those questions whose answers invite us to embrace any such idealism. But the main thesis of the essay remains intact. Indeed the idea that Wittgenstein’s later work precludes a philosophically substantial theory of meaning is reinforced. (shrink)

It is argued that the use/mention distinction, if it is to be a clear-cut one, cannot have the significance that it is usually thought to have. For that significance attaches to the distinction between employing an expression in order to draw attention to, or to talk about, some aspect of the world, as determined by the expression’s meaning, and employing it in order to draw attention to, or to talk about, the expression itself—and this distinction is not a clear-cut one. (...) In the final section of the essay this argument is extended to cast doubt on a rather glib appeal to the use/mention distinction that is frequently made in the philosophy of language. (shrink)

It is argued that, although there are no ineffable truths, the concept of ineffability nevertheless does have application—to certain states of knowledge. Towards the end of the essay this idea is related to religion: it is argued that the language that results from attempting (unsuccessfully) to put ineffable knowledge into words is very often of a religious kind. An example of this is given at the very end of the essay. This example concerns the Euthyphro question: whether what is right (...) is right because God wills it, or whether God wills it because it is right. (shrink)

The aim of this essay is to characterize the issue whether tense is real. Roughly, this is the issue whether, given any tensed representation, its tense corresponds in some suitably direct way to some feature of reality. The task is to make this less rough. Eight characterizations of the issue are considered and rejected, before one is endorsed. On this characterization, the unreality of tense is equivalent to the unity of temporal reality. The issue whether tense is real, so characterized, (...) is then related to Kant’s deduction of the categories in his Critique of Pure Reason. It is argued that Kant’s deduction does not provide the argument for the unreality of tense that it may appear to. The conclusion drawn at the end of the essay is that the unreality of tense cannot be argued for—not because tense is real, but because, even if it is unreal, its unreality is basic. (shrink)

This essay is concerned with six linguistic moves that we commonly make, each of which is considered in turn. These are: stating rules of representation; representing things categorically; mentioning expressions; saying truly or falsely how things are; saying vaguely how things are; and stating rules of rules of representation. A common-sense view is defended of what is involved in our doing each of these six things against a much more sceptical view emanating from the idea that linguistic behavior is fundamentally (...) messy. Both the fifth move and the sixth move involve vague concepts, and much of the essay is concerned with developing an approach to various problems and puzzles that attach to such concepts, most notably the sorites paradoxes.

Artificial intelligence (AI) systems have demonstrated impressive performance across a variety of clinical tasks. However, notoriously, sometimes these systems are 'black boxes'. The initial response in the literature was a demand for 'explainable AI'. However, recently, several authors have suggested that making AI more explainable or 'interpretable' is likely to be at the cost of the accuracy of these systems and that prioritising interpretability in medical AI may constitute a 'lethal prejudice'. In this paper, we defend the value of interpretability (...) in the context of the use of AI in medicine. Clinicians may prefer interpretable systems over more accurate black boxes, which in turn is sufficient to give designers of AI reason to prefer more interpretable systems in order to ensure that AI is adopted and its benefits realised. Moreover, clinicians may be justified in this preference. Achieving the downstream benefits from AI is critically dependent on how the outputs of these systems are interpreted by physicians and patients. A preference for the use of highly accurate black box AI systems, over less accurate but more interpretable systems , may itself constitute a form of lethal prejudice that may diminish the benefits of AI to - and perhaps even harm - patients.

An interpretation of Kant's first antinomy is defended whereby both its thesis and its antithesis depend on a common basic principle that Kant endorses, namely that there cannot be an ‘infinite contingency’, by which is meant a contingent fact about how an infinite region of space or time is occupied. The greatest problem with this interpretation is that Kant explicitly declines to apply counterparts of the temporal arguments in the antinomy to the world’s future, even though, if the interpretation is (...) correct, such arguments are clearly there to be applied. This problem, it is argued, is surmountable. (shrink)

Results: We analyzed 1,402 surveys and 15 in-depth interviews. Many (32%) CL participants reported greater difficulty refilling medications and a minority (14%) reported greater difficulty accessing HIV care during the pandemic. Most (99%) Opt4Mamas participants reported no difficulty refilling medications or accessing HIV/pregnancy care. Among the CL participants, older women were less likely (aOR = 0.95, 95% CI: 0.92–0.98) and women with more children were more likely (aOR = 1.13, 95% CI: 1.00–1.28) to report difficulty refilling medications. Only 2% of (...) CL participants reported greater difficulty managing FP and most (95%) reported no change in likelihood of using FP or desire to get pregnant. Qualitative analysis revealed three major themes: (1) adverse organizational/economic implications of the pandemic, (2) increased importance of pregnancy prevention during the pandemic, and (3) fear of contracting COVID-19.

This essay is concerned with solipsism, understood as the extreme sceptical view that I have no knowledge except of my subjective state. A less rough formulation of the view is mooted, inspired by a Quinean combination of naturalism and empiricism. An objection to the resultant position is then considered, based on Putnam’s argument that we are not brains in vats. This objection is first outlined, then pitted against a series of counter-objections. Eventually it is endorsed, but only at the price (...) of exposing the formulation of solipsism in question as not, after all, a satisfactory formulation. This leads to further speculation about the status of solipsism itself. Two of the possibilities that are considered are, firstly, that it is incoherent and, secondly, that it is inexpressible.

This essay appeared as a contribution to a special issue of European Journal of Philosophy to mark the fiftieth anniversary of the publication of P. F. Strawson’s The Bounds of Sense. In that book Strawson asks whether we should agree with Kant's claim, in his Critique of Pure Reason, that there can be only one world. What Kant means by this claim is that the four-dimensional realm that we inhabit must constitute the whole of empirical reality. Strawson gives reasons for (...) challenging this claim. This essay raises the question whether, even if Strawson is right, we may nevertheless have reason to believe that there can be only one world on a broader understanding of ‘world’. The aim is as much to clarify the issue as to settle it, although an attempt is made to motivate the view that there can indeed be only one world on this broader understanding. (shrink)

In this essay I focus on the idea of the univocity of being, championed by Duns Scotus and given prominence more recently by Deleuze. Although I am interested in how this idea can be established, my primary concern is with something more basic: how the idea can even be properly thought. In the course of exploring this issue, which I do partly by borrowing some ideas about logical syntax from Wittgenstein's Tractatus, I try to show how there can be dialogue (...) between analytic philosophers and those of other traditions.

Two of Quine's most familiar doctrines are: that there is a distinction between underdetermination and indeterminacy; and that there is no distinction between analytic and synthetic truths. An argument is given that these two doctrines are incompatible. In terms wholly acceptable to Quine and based on the underdetermination/indeterminacy distinction, an exhaustive and exclusive distinction is drawn between two kinds of true sentences, which, it is argued, corresponds to the traditional analytic/synthetic distinction. An appendix is used to develop one aspect of (...) the underdetermination/indeterminacy distinction, as construed here, and to discuss, in passing, some of Quine’s more general views on truth.

This essay is concerned with Graham Bird’s treatment, in The Revolutionary Kant, of Kant’s mathematical antinomies. On Bird’s interpretation, our error in these antinomies is to think that we can settle certain issues about the limits of physical reality by pure reason whereas in fact we cannot settle them at all. On the rival interpretation advocated in this essay, it is not true that we cannot settle these issues. Our error is to presuppose that the concept of the unconditioned has (...) application to physical reality. Once this presupposition has been abandoned, we can retrieve sound arguments from the antinomies, not indeed to demonstrate that the views originally being defended are correct, but to demonstrate that the views originally being attacked are incorrect. The essay concludes with some comments concerning how this disagreement relates to a broader disagreement about the best way to understand Kant. (shrink)

Betrachtet man den Gebrauch der Worte ‘Moral’ und ‘Vernunft’ etwas genauer, so stellt man fest, dass nicht klar ist, was sie bezeichnen bzw. wie Moral und Vernunft zusammenhängen. In dem Buch ‘Rationalität in der Angewandten Ethik’, in dem sich verschiedene Autoren die Aufgabe gestellt haben, diese Umstände in das Licht der Betrachtung zu rücken, finden wir Fragen darüber, wie “Moral”, “Angewandte Ethik” und “Vernunft” (auch in der Anwendung) zu verstehen und zu vereinen sind.

Understanding the autonomic nervous system and homeostatic changes associated with emotions remains a major challenge for neuroscientists and a fundamental prerequisite to treat anxiety, stress, and emotional disorders. Based on recent publications, the inter-relationship between respiration and emotions and the influence of respiration on autonomic changes, and subsequent widespread membrane potential changes resulting from changes in homeostasis are discussed. We hypothesize that reversing homeostatic alterations with meditation and breathing techniques rather than targeting neurotransmitters with medication may be a superior method (...) to address the whole body changes that occur in stress, anxiety, and depression. Detrimental effects of stress, negative emotions, and sympathetic dominance of the autonomic nervous system have been shown to be counteracted by different forms of meditation, relaxation, and breathing techniques. We propose that these breathing techniques could be used as firstline and supplemental treatments for stress, anxiety, depression, and some emotional disorders. (shrink)

In this paper we examine the ethical implications of emerging Nanotechnologically Enhanced Combat Systems (or 'NECS'). Through a combination of materials innovation and biotechnology, NECS are aimed at making combatants much less vulnerable to munitions that pose a lethal threat to soldiers protected by conventional armor. We argue that increasing technological disparities between forces armed with NECS and those without will exacerbate the ethical problems of asymmetric warfare. This will place pressure on the just war principles of jus in bello, (...) by encouraging the resort to tactics that either (i) make it more difficult to respect these principles or (ii) directly violate them, by virtue of attacking non-combatants or creating disproportionate numbers of casualties without a clear military goal.

Pranayamic breathing, defined as a manipulation of breath movement, has been shown to contribute to a physiologic response characterized by the presence of decreased oxygen consumption, decreased heart rate, and decreased blood pressure, as well as increased theta wave amplitude in EEG recordings, increased parasympathetic activity accompanied by the experience of alertness and reinvigoration. The mechanism of how pranayamic breathing interacts with the nervous system affecting metabolism and autonomic functions remains to be clearly understood. It is our hypothesis that voluntary (...) slow deep breathing functionally resets the autonomic nervous system through stretchinduced inhibitory signals and hyperpolarization currents propagated through both neural and non-neural tissue which synchronizes neural elements in the heart, lungs, limbic system and cortex. During inspiration, stretching of lung tissue produces inhibitory signals by action of slowly adapting stretch receptors (SARs) and hyperpolarization current by action of fibroblasts. Both inhibitory impulses and hyperpolarization current are known to synchronize neural elements leading to the modulation of the nervous system and decreased metabolic activity indicative of the parasympathetic state. In this paper we propose pranayama’s physiologic mechanism through a cellular and systems level perspective,involving both neural and non-neural elements. This theoretical description describes a common physiological mechanism underlying pranayama and elucidate the role of the respiratory and cardiovascular system on modulating the autonomic nervous system. Along with facilitating the design of clinical breathing techniques for the treatment of autonomic nervous system and other disorders, this model will also validate pranayama as a topic requiring more research.

In, “The Turing Triage Test”, published in Ethics and Information Technology, I described a hypothetical scenario, modelled on the famous Turing Test for machine intelligence, which might serve as means of testing whether or not machines had achieved the moral standing of people. In this paper, I: (1) explain why the Turing Triage Test is of vital interest in the context of contemporary debates about the ethics of AI; (2) address some issues that complexify the application of this test; and, (...) (3) in doing so, defend a way of thinking about the question of the moral standing of intelligent machines, which takes the idea of “seriousness” seriously. This last objective is, in fact, my primary one and is motivated by the sense that, to date, much of the “philosophy” of AI has suffered from a profound failure to properly distinguish between things that we can say and things that we can really mean.

In Deep Medicine, Eric Topol argues that the development of artificial intelligence (AI) for healthcare will lead to a dramatic shift in the culture and practice of medicine. Topol claims that, rather than replacing physicians, AI could function alongside of them in order to allow them to devote more of their time to face-to-face patient care. Unfortunately, these high hopes for AI-enhanced medicine fail to appreciate a number of factors that, we believe, suggest a radically different picture for the future (...) of healthcare. Far from facilitating a return to “the golden age of doctoring”, the role of economic and institutional considerations in determining how medical AI will be used mean that it is likely to further erode therapeutic relationships and threaten professional and patient satisfaction.

Objectives: Machine learning (ML) has the potential to facilitate “continual learning” in medicine, in which an ML system continues to evolve in response to exposure to new data over time, even after being deployed in a clinical setting. In this article, we provide a tutorial on the range of ethical issues raised by the use of such “adaptive” ML systems in medicine that have, thus far, been neglected in the literature. -/- Target audience: The target audiences for this tutorial are (...) the developers of ML AI systems, healthcare regulators, the broader medical informatics community, and practicing clinicians. -/- Scope: Discussions of adaptive ML systems to date have overlooked the distinction between 2 sorts of variance that such systems may exhibit—diachronic evolution (change over time) and synchronic variation (difference between cotemporaneous instantiations of the algorithm at different sites)—and underestimated the significance of the latter. We highlight the challenges that diachronic evolution and synchronic variation present for the quality of patient care, informed consent, and equity, and discuss the complex ethical trade-offs involved in the design of such systems.

We present counterexamples to the widespread assumption that Moorean sentences cannot be rationally asserted. We then explain why Moorean assertions of the sort we discuss do not incur the irrationality charge. Our argument involves an appeal to the dual-process theory of the mind and a contrast between the conditions for ascribing beliefs to oneself and the conditions for making assertions about independently existing states of affairs. We conclude by contrasting beliefs of the sort we discuss with the structurally similar but (...) rationally impermissible beliefs of certain psychiatric patients. (shrink)

Nudging works through dispositions to decide with specific heuristics, and has three component parts. A nudge is a feature of an environment that enables such a disposition; a person is nudged when such a disposition is triggered; and a person performs a nudged action when such a disposition manifests in action. This analysis clarifies an autonomy-based worry about nudging as used in public policy or for private profit: that a person’s ability to reason well is undermined when she is nudged. (...) Reasoning well is a component of self-guidance, which is an aspect of autonomy and so something there is reason to promote, preserve, or respect. However, a person can reason well when she is nudged: Many of these heuristics are good rules to reason with, and she can be flexible with respect to them when she takes there to be a better way to reason. Along the way, this paper uncovers several design specifications for responsible nudging, and discusses open empirical questions. However, nudging’s being compatible with reasoning well crystallizes a distinct worry about manipulation: that nudge designers can rely on nudged people guiding themselves toward the designers’ own ends. Manipulation of this sort exploits one aspect of autonomy (namely, self-guidance) to undermine autonomy in other respects. (shrink)

In this paper, I explore the “expressivist critique” of the use of prenatal testing to select against the birth of persons with impairments. I begin by setting out the expressivist critique and then highlighting, through an investigation of an influential objection to this critique, the ways in which both critics and proponents of the use of technologies of genetic selection negotiate a difficult set of dilemmas surrounding the relationship between genes and identity. I suggest that we may be able to (...) advance the debate about these technologies by becoming more aware of the ways in which this debate is itself in part a political contestation over this relationship. Ultimately, I will argue, the real force of the expressivist objection lies in its capacity to draw our attention to political questions about the role of the state and about relationships between different social groups rather than between parents and prospective children. That is to say, crucial issues, when evaluating the force of this criticism, turn out to be: the nature of the institutions which determine how decisions about prenatal selection are made; and how we think of each other, that is, what we take to be the defining characteristics of human beings. Paradoxically, arguments about the ethics of the “sorting society”, both supportive and critical, are an important arena in which these institutions and these ideas about identity are contested and shaped. An increased awareness of the reflexive nature of the process of debating these issues may assist us in better negotiating them. (shrink)

Would it be ethical to deploy autonomous weapon systems (AWS) if they were unable to reliably recognize when enemy forces had surrendered? I suggest that an inability to reliably recognize surrender would not prohibit the ethical deployment of AWS where there was a limited window of opportunity for targets to surrender between the launch of the AWS and its impact. However, the operations of AWS with a high degree of autonomy and/or long periods of time between release and impact are (...) likely to remain controversial until they have the capacity to reliably recognize surrender.

Stress profoundly impacts quality of life and may lead to various diseases and conditions. Understanding the underlying physiological and neurological processes that take place during stress and meditation techniques may be critical for effectively treating stress-related diseases. The article examines a hypothetical physiological homeostatic response that compares and contrasts changes in central and peripheral oscillations during stress and meditation, and relates these to changes in the autonomic system and neurological activity. The authors discuss how cardiorespiratory synchronization, which occurs during the (...) parasympathetic response and meditation, influences and modulates activity and oscillations of the brain and autonomic nervous system. Evidence is presented on how synchronization of cardiac and respiratory rates during meditation may lead to a homeostatic increase in cellular membrane potentials in neurons and other cells throughout the body. These potential membrane changes may underlie the reduced activity in the amygdala, and other cortical areas during meditation, and research examining these changes may foster better understanding of the restorative properties and health benefits of meditation.

In their paper, “Autonomy and the ethics of biological behaviour modification”, Savulescu, Douglas, and Persson discuss the ethics of a technology for improving moral motivation and behaviour that does not yet exist and will most likely never exist. At the heart of their argument sits the imagined case of a “moral technology” that magically prevents people from developing intentions to commit seriously immoral actions. It is not too much of a stretch, then, to characterise their paper as a thought experiment (...) in service of a thought experiment. In order for an argument involving a thought experiment to progress debate in applied ethics three things must be true. First, the thought experiment must accurately represent and illuminate a pressing ethical dilemma. Second – and most obviously – the central claims of the argument regarding the thought experiment must be plausible. Third, it must be possible to apply or develop the arguments established with reference to the thought experiment to the real world cases the experiment is intended to illuminate. In this commentary, I argue that there are serious reasons to question the extent to which their argument meets each of these challenges involved in the use of thought experiments in applied ethics. While Savulescu et al. succeed in showing how behavioural modification might be compatible with freedom and autonomy – and perhaps justifiable even if it were not — in the fantastic case they consider, there is little we can conclude from this about any technology of “moral bioenhancement” in the foreseeable future. Indeed, there is a real danger that their argument will license attempts to manipulate behaviour through drugs and brain implants, which raise profound moral issues that they barely mention. (shrink)
