The _Physics_ is a foundational work of western philosophy, and the crucial one for understanding Aristotle's views on matter, form, essence, causation, movement, space, and time. This richly annotated, scrupulously accurate, and consistent translation makes it available to a contemporary English reader as no other does—in part because it fits together seamlessly with other closely associated works in the New Hackett Aristotle series, such as the _Metaphysics_, _De Anima_, and forthcoming _De Caelo_ and _On Coming to Be and Passing Away_. (...) Eventually the series will include all of Aristotle's works. Sequentially numbered endnotes provide the information most needed at each juncture, while a detailed Index of Terms indicates places where focused discussion of key notions occurs. An illuminating general Introduction describes the book that lies ahead, explaining what sort of work it is and what sorts of evidence it relies on. (shrink)

David Hume's Enquiry concerning Human Understanding is the definitive statement of the greatest philosopher in the English language. His arguments in support of reasoning from experience, and against the "sophistry and illusion"of religiously inspired philosophical fantasies, caused controversy in the eighteenth century and are strikingly relevant today, when faith and science continue to clash. The Enquiry considers the origin and processes of human thought, reaching the stark conclusion that we can have no ultimate understanding of the physical world, or indeed (...) our own minds. In either sphere we must depend on instinctive learning from experience, recognizing our animal nature and the limits of reason. Hume's calm and open-minded skepticism thus aims to provide a new basis for science, liberating us from the "superstition" of false metaphysics and religion. His Enquiry remains one of the best introductions to the study of philosophy, and his edition places it in its historical and philosophical context. (shrink)

This paper argues that the medical conception of health as absence of disease is a value-free theoretical notion. Its main elements are biological function and statistical normality, in contrast to various other ideas prominent in the literature on health. Apart from universal environmental injuries, diseases are internal states that depress a functional ability below species-typical levels. Health as freedom from disease is then statistical normality of function, i.e., the ability to perform all typical physiological functions with at least typical efficiency. (...) This conception of health is as value-free as statements of biological function. The view that health is essentially value-laden, held by most writers on the topic, seems to have one of two sources: an assumption that health judgments must be practical judgments about the treatment of patients, or a commitment to "positive" health beyond the absence of disease. I suggest that the assumption is mistaken, the commitment possibly misdescribed. (shrink)

Everyone has heard the claim, "Correlation does not imply causation." What might sound like a reasonable dictum metastasized in the twentieth century into one of science's biggest obstacles, as a legion of researchers became unwilling to make the claim that one thing could cause another. Even two decades ago, asking a statistician a question like "Was it the aspirin that stopped my headache?" would have been like asking if he believed in voodoo, or at best a topic for conversation at (...) a cocktail party rather than a legitimate target of scientific inquiry. Scientists were allowed to posit only that the probability that one thing was associated with another. This all changed with Judea Pearl, whose work on causality was not just a victory for common sense, but a revolution in the study of the world. (shrink)

The prospective robots in healthcare intended to be included within the conclave of the nurse-patient relationship—what I refer to as care robots—require rigorous ethical reflection to ensure their design and introduction do not impede the promotion of values and the dignity of patients at such a vulnerable and sensitive time in their lives. The ethical evaluation of care robots requires insight into the values at stake in the healthcare tradition. What’s more, given the stage of their development and lack of (...) standards provided by the International Organization for Standardization to guide their development, ethics ought to be included into the design process of such robots. The manner in which this may be accomplished, as presented here, uses the blueprint of the Value-sensitive design approach as a means for creating a framework tailored to care contexts. Using care values as the foundational values to be integrated into a technology and using the elements in care, from the care ethics perspective, as the normative criteria, the resulting approach may be referred to as care centered value-sensitive design. The framework proposed here allows for the ethical evaluation of care robots both retrospectively and prospectively. By evaluating care robots in this way, we may ultimately ask what kind of care we, as a society, want to provide in the future. (shrink)

It is remarkable how much robotics research is promoted by appealing to the idea that the only way to deal with a looming demographic crisis is to develop robots to look after older persons. This paper surveys and assesses the claims made on behalf of robots in relation to their capacity to meet the needs of older persons. We consider each of the roles that has been suggested for robots in aged care and attempt to evaluate how successful robots might (...) be in these roles. We do so from the perspective of writers concerned primarily with the quality of aged care, paying particular attention to the social and ethical implications of the introduction of robots, rather than from the perspective of robotics, engineering, or computer science. We emphasis the importance of the social and emotional needs of older persons—which, we argue, robots are incapable of meeting—in almost any task involved in their care. Even if robots were to become capable of filling some service roles in the aged-care sector, economic pressures on the sector would most likely ensure that the result was a decrease in the amount of human contact experienced by older persons being cared for, which itself would be detrimental to their well-being. This means that the prospects for the ethical use of robots in the aged-care sector are far fewer than first appears. More controversially, we believe that it is not only misguided, but actually unethical, to attempt to substitute robot simulacra for genuine social interaction. A subsidiary goal of this paper is to draw attention to the discourse about aged care and robotics and locate it in the context of broader social attitudes towards older persons. We conclude by proposing a deliberative process involving older persons as a test for the ethics of the use of robots in aged care. (shrink)

Distinctions have been proposed between systems of reasoning for centuries. This article distills properties shared by many of these distinctions and characterizes the resulting systems in light of recent findings and theoretical developments. One system is associative because its computations reflect similarity structure and relations of temporal contiguity. The other is "rule based" because it operates on symbolic structures that have logical content and variables and because its computations have the properties that are normally assigned to rules. The systems serve (...) complementary functions and can simultaneously generate different solutions to a reasoning problem. The rule-based system can suppress the associative system but not completely inhibit it. The article reviews evidence in favor of the distinction and its characterization. (shrink)

This paper explores the relationship between dignity and robot care for older people. It highlights the disquiet that is often expressed about failures to maintain the dignity of vulnerable older people, but points out some of the contradictory uses of the word ‘dignity’. Certain authors have resolved these contradictions by identifying different senses of dignity; contrasting the inviolable dignity inherent in human life to other forms of dignity which can be present to varying degrees. The Capability Approach (CA) is introduced (...) as a different but tangible account of what it means to live a life worthy of human dignity. It is used here as a framework for the assessment of the possible effects of eldercare robots on human dignity. The CA enables the identification of circumstances in which robots could enhance dignity by expanding the set of capabilities that are accessible to frail older people. At the same time, it is also possible within its framework to identify ways in which robots could have a negative impact, by impeding the access of older people to essential capabilities. It is concluded that the CA has some advantages over other accounts of dignity, but that further work and empirical study is needed in order to adapt it to the particular circumstances and concerns of those in the latter part of their lives.

Over the last quarter century, the dominant tendency in comparative cognitive psychology has been to emphasize the similarities between human and nonhuman minds and to downplay the differences as (Darwin 1871). In the present target article, we argue that Darwin was mistaken: the profound biological continuity between human and nonhuman animals masks an equally profound discontinuity between human and nonhuman minds. To wit, there is a significant discontinuity in the degree to which human and nonhuman animals are able to approximate (...) the higher-order, systematic, relational capabilities of a physical symbol system (PSS) (Newell 1980). We show that this symbolic-relational discontinuity pervades nearly every domain of cognition and runs much deeper than even the spectacular scaffolding provided by language or culture alone can explain. We propose a representational-level specification as to where human and nonhuman animals' abilities to approximate a PSS are similar and where they differ. We conclude by suggesting that recent symbolic-connectionist models of cognition shed new light on the mechanisms that underlie the gap between human and nonhuman minds. (shrink)

An aging population is often taken to require a profound reorganization of the prevailing health care system. In particular, a more cost-effective care system is warranted and ICT-based home care is often considered a promising alternative. Modern health care devices admit a transfer of patients with rather complex care needs from institutions to the home care setting. With care recipients set up with health monitoring technologies at home, spouses and children are likely to become involved in the caring process and (...) informal caregivers may have to assist kin-persons with advanced care needs by means of sophisticated technology. This paper investigates some of the ethical implications of a near-future shift from institutional care to technology-assisted home care and the subsequent impact on the care recipient and formal- and informal care providers.

Globally, the population of elderly people is rising with an increasing number of people living with dementias. This trend is coupled with a prevailing need for compassionate caretakers. A key challenge in dementia care is to assist the person to sustain communication and connection to family, caregivers and the environment. The use of social commitment robots in the care of people with dementia has intriguing possibilities to address some of these care needs. This paper discusses the literature on the use (...) of social commitment robots in the care of elderly people with dementia; the contributions to care that social commitment robots potentially can make and the cautions around their use. Future directions for programs of research are identified to further the development of the evidence-based knowledge in this area. (shrink)

The internet of things is increasingly spreading into the domain of medical and social care. Internet-enabled devices for monitoring and managing the health and well-being of users outside of traditional medical institutions have rapidly become common tools to support healthcare. Health-related internet of things (H-IoT) technologies increasingly play a key role in health management, for purposes including disease prevention, real-time tele-monitoring of patient’s functions, testing of treatments, fitness and well-being monitoring, medication dispensation, and health research data collection. H-IoT promises many (...) benefits for health and healthcare. However, it also raises a host of ethical problems stemming from the inherent risks of Internet enabled devices, the sensitivity of health-related data, and their impact on the delivery of healthcare. This paper maps the main ethical problems that have been identified by the relevant literature and identifies key themes in the on-going debate on ethical problems concerning H-IoT. (shrink)

Considers that intuitive predictions follow a judgmental heuristic-representativeness. By this heuristic, people predict the outcome that appears most representative of the evidence. Consequently, intuitive predictions are insensitive to the reliability of the evidence or to the prior probability of the outcome, in violation of the logic of statistical prediction. The hypothesis that people predict by representativeness was supported in a series of studies with both naive and sophisticated university students. The ranking of outcomes by likelihood coincided with the ranking by (...) representativeness, and Ss erroneously predicted rare events and extreme values if these happened to be representative. The experience of unjustified confidence in predictions and the prevalence of fallacious intuitions concerning statistical regression are traced to the representativeness heuristic. (shrink)

Philosophical discussions of health and disease have traditionally been dominated by a debate between normativists, who hold that health is an inescapably value-laded concept and naturalists, such as Christopher Boorse, who believe that it is possible to derive a purely descriptive or theoretical definition of health based upon biological function. In this paper I defend a distinctive view which traces its origins in Aristotle's naturalistic ethics. An Arisotelian would agree with Boorse that health and disease are ubiquitous features of the (...) natural world and thus not mere projections of human interests and values. She would differ from him in rejecting the idea that value is a non-natural quality. I conclude my discussion with some comments of the normative character of living systems. (shrink)

Heuristics are efficient cognitive processes that ignore information. In contrast to the widely held view that less processing reduces accuracy, the study of heuristics shows that less information, computation, and time can in fact improve accuracy. We review the major progress made so far: the discovery of less-is-more effects; the study of the ecological rationality of heuristics, which examines in which environments a given strategy succeeds or fails, and why; an advancement from vague labels to computational models of heuristics; the (...) development of a systematic theory of heuristics that identifies their building blocks and the evolved capacities they exploit, and views the cognitive system as relying on an “adaptive toolbox;” and the development of an empirical methodology that accounts for individual differences, conducts competitive tests, and has provided evidence for people’s adaptive use of heuristics. Homo heuristicus has a biased mind and ignores part of the available information, yet a biased mind can handle uncertainty more efficiently and robustly than an unbiased mind relying on more resource-intensive and general-purpose processing strategies.

Gerontologists have proposed different concepts for ageing well such as ‘successful ageing’, ‘active ageing’, and ‘healthy ageing’. These conceptions are primarily focused on maintaining health and preventing disease. But they also raise the questions: what is a good life in old age and how can it be achieved? While medical in origin, these concepts and strategies for ageing well also contain ethical advice for individuals and societies on how to act regarding ageing and old age. This connection between gerontology and (...) ethics is overlooked by both schools of thought. We thus develop this research programme for a systematic geroethics in four steps. First, we analyze ‘successful ageing’ as put forward by Rowe and Kahn as a paradigmatic example of a gerontological conception of ageing well. Then, in a second step, we move from criticisms within gerontology to an ethical perspective; in particular, we want to clarify the problem of the claim of universal validity of conceptions of the good life. In a third constructive step, we explain how the ‘capabilities approach’ could be applied in this context as a normative foundation for the implicit normative assumptions of gerontological conceptions of ageing well, such as a particular choice of functionings, the ethical relevance of human agency, and the resulting claims of individuals towards society. Finally, using a concept developed by the German philosopher Ursula Wolf, we systematically develop the different aspects of the connection between ageing well and the theory of the good life in their full complexity and show their interconnectedness.

Scenarios involving the introduction of artificially intelligent (AI) assistive technologies in health care practices raise several ethical issues. In this paper, I discuss four objections to introducing AI assistive technologies in health care practices as replacements of human care. I analyse them as demands for felt care, good care, private care, and real care. I argue that although these objections cannot stand as good reasons for a general and a priori rejection of AI assistive technologies as such or as replacements (...) of human care, they demand us to clarify what is at stake, to develop more comprehensive criteria for good care, and to rethink existing practices of care. In response to these challenges, I propose a (modified) capabilities approach to care and emphasize the inherent social dimension of care. I also discuss the demand for real care by introducing the ‘Care Experience Machine’ thought experiment. I conclude that if we set the standards of care too high when evaluating the introduction of AI assistive technologies in health care, we have to reject many of our existing, low-tech health care practices.

This paper attempts to make more explicit the relationship between narrativity and feminist care ethics. The central concern is the way in which narrativity carries the semantic load that some accounts of feminist care ethics imply but leave hanging. In so doing, some feminist theorists of care-based ethics then undervalue the major contribution that narrativity provides to care ethics: it carries the semantic load that is essential to the best care. In this article, I defend the narrative as the central (...) medium though which we make sense of and communicate our lives and their attendant hopes and cares. More than just working with the narrative of the cared-for, caring is about investing in the narrative of the cared-for in order to meet the needs of this cared-for and how this narrative might turn out. I will further demonstrate how the attitude of caring or investing in a narrative would amount to what Gabriel Marcel has described as the attitude of disponibilité. (shrink)

The phenomenon of base-rate neglect has elicited much debate. One arena of debate concerns how people make judgments under conditions of uncertainty. Another more controversial arena concerns human rationality. In this target article, we attempt to unpack the perspectives in the literature on both kinds of issues and evaluate their ability to explain existing data and their conceptual coherence. From this evaluation we conclude that the best account of the data should be framed in terms of a dual-process model of (...) judgment, which attributes base-rate neglect to associative judgment strategies that fail to adequately represent the set structure of the problem. Base-rate neglect is reduced when problems are presented in a format that affords accurate representation in terms of nested sets of individuals. (shrink)

Causality offers the first comprehensive coverage of causal analysis in many sciences, including recent advances using graphical methods. Pearl presents a unified account of the probabilistic, manipulative, counterfactual and structural approaches to causation, and devises simple mathematical tools for analyzing the relationships between causal connections, statistical associations, actions and observations. The book will open the way for including causal analysis in the standard curriculum of statistics, artificial intelligence, business, epidemiology, social science and economics.

In this major book Martha Nussbaum, one of the most innovative and influential philosophical voices of our time, proposes a kind of feminism that is genuinely international, argues for an ethical underpinning to all thought about development planning and public policy, and dramatically moves beyond the abstractions of economists and philosophers to embed thought about justice in the concrete reality of the struggles of poor women. Nussbaum argues that international political and economic thought must be sensitive to gender difference as (...) a problem of justice, and that feminist thought must begin to focus on the problems of women in the third world. Taking as her point of departure the predicament of poor women in India, she shows how philosophy should undergird basic constitutional principles that should be respected and implemented by all governments, and used as a comparative measure of quality of life across nations.

The human brain has some capabilities that the brains of other animals lack. It is to these distinctive capabilities that our species owes its dominant position. Other animals have stronger muscles or sharper claws, but we have cleverer brains. If machine brains one day come to surpass human brains in general intelligence, then this new superintelligence could become very powerful. As the fate of the gorillas now depends more on us humans than on the gorillas themselves, so the fate of (...) our species then would come to depend on the actions of the machine superintelligence. But we have one advantage: we get to make the first move. Will it be possible to construct a seed AI or otherwise to engineer initial conditions so as to make an intelligence explosion survivable? How could one achieve a controlled detonation? To get closer to an answer to this question, we must make our way through a fascinating landscape of topics and considerations. Read the book and learn about oracles, genies, singletons; about boxing methods, tripwires, and mind crime; about humanity's cosmic endowment and differential technological development; indirect normativity, instrumental convergence, whole brain emulation and technology couplings; Malthusian economics and dystopian evolution; artificial intelligence, and biological cognitive enhancement, and collective intelligence.

Five studies investigated (a) children’s ability to use the dependent and independent probabilities of events to make causal inferences and (b) the interaction between such inferences and domain-specific knowledge. In Experiment 1, preschoolers used patterns of dependence and independence to make accurate causal inferences in the domains of biology and psychology. Experiment 2 replicated the results in the domain of biology with a more complex pattern of conditional dependencies. In Experiment 3, children used evidence about patterns of dependence and independence (...) to craft novel interventions across domains. In Experiments 4 and 5, children’s sensitivity to patterns of dependence was pitted against their domain-specific knowledge. Children used conditional probabilities to make accurate causal inferences even when asked to violate domain boundaries. (shrink)

The debate about the use of robots in the care of older adults has often been dominated by either overly optimistic visions (coming particularly from Japan), in which robots are seamlessly incorporated into society thereby enhancing quality of life for everyone; or by extremely pessimistic scenarios that paint such a future as horrifying. We reject this dichotomy and argue for a more differentiated ethical evaluation of the possibilities and risks involved with the use of social robots. In a critical discussion (...) surrounding the capabilities approach to the ethical evaluation of quality of life, we develop an ethical framework that is more appropriate to the situation of the oldest old. We urge employment of a context-dependent approach to the ethical evaluation of new technologies in the care and therapy of older adults, and using the example of the robotic seal Paro, we show how this can be accomplished in a sensible and practical way.
