Research suggests that the reaching hand automatically deviates toward a target that changes location during the reach. In the current study, we investigated whether movement intention can influence the target jump’s impact on the hand. We compared the degree of trajectory deviation to a jumped target under three instruction conditions: GO, in which participants were told to go to the target if it jumped, STOP, in which participants were told to immediately stop their movement if the target jumped, and IGNORE, (...) in which participants were told to ignore the target if it jumped and to continue to its initial location. We observed a reduced response to the jump in the IGNORE condition relative to the other conditions, suggesting that the response to the jump is contingent on the jump being a task-relevant event.

Research suggests that perceptual experience of our movements adapts together with movement control when we are the agents of our actions. Is this agency critical for perceptual and motor adaptation? We had participants view cursor feedback during elbow extension–flexion movements when they actively moved their arm, or had their arm passively moved. We probed adaptation of movement perception by having participants report the reversal point of their unseen movement. We probed adaptation of movement control by having them aim to a (...) target. Perception and control of active movement were influenced by both types of exposure, although adaptation was stronger following active exposure. Furthermore, both types of exposure led to a change in the perception of passive movements. Our findings support the notion that perception and control adapt together, and they suggest that some adaptation is due to recalibrated proprioception that arises independently of active engagement with the environment.

A considerable literature exists regarding the moral obligation to keep one's promises. Several authors have focused on the exceptional circumstances which may or should excuse this moral duty. Less frequently discussed is the question of how this general moral obligation and its possible exceptions play out in the context of negotiable written promises to pay money, i.e., so-called "commercial paper." This paper focuses on the application of the legal rules governing commercial paper, and on the ethical implications involved in the (...) application of those rules. More specifically, it asks whether the assertion of the technical doctrine known as "holder in due course," and the denial of that status in some cases, promotes ethical behavior in the marketplace. By examining the circumstances of one case, involving a substantial investment and a large bank, I hope to shed some light on how the legal and ethical rules do in fact "intersect.". (shrink)

Erving Goffman’s “Asylums” is a key text in the development of contemporary, community-orientated mental health practice. It has survived as a trenchant critique of the asylum as total institution, and its publication in 1961 in book form marked a further stage in the discrediting of the asylum model of mental health care. In this paper, some responses from a range of disciplines to this text, 50 years on, are presented. A consultant psychiatrist with a special interest in cultural psychiatry and (...) mental health legislation, two collaborating psychotherapists in adult and forensic mental health, a philosopher, and a recent medical graduate, present their varying responses to the text. The editors present these with the hope of encouraging further dialogue and debate from service users, carers, clinicians, and academics and researchers across a range of disciplines. (shrink)

AI safety is an interdisciplinary field focused on mitigating the harms caused by AI systems. We review a range of research directions in AI safety, focusing on those to which philosophers have made or are in a position to make the most significant contributions. These include ethical AI, which seeks to instill human goals, values, and ethical principles into artificial systems, scalable oversight, which seeks to develop methods for supervising the activity of artificial systems even when they become significantly more (...) capable than their human designers, interpretability, which seeks to render comprehensible the workings of complex machine learning models, and corrigibility, which seeks to discover ways to ensure that powerful AI systems will not resist being shut down or modified by humans.

Among ancient writers Aristotle offers the most profound analysis of the ancient Greek household and its relationship to the state. The household was not the family in the modern sense of the term, but a much more powerful entity with significant economic, political, social, and educational resources. The success of the polis in all its forms lay in the reliability of households to provide it with the kinds of citizens it needed to ensure its functioning. In turn, the state offered (...) the members of its households a unique opportunity for humans to flourish. This 2006 book explains how Aristotle thought household and state interacted within the polis. (shrink)

Research involving recently deceased humans that are physiologically maintained following declaration of death by neurologic criteria—or ‘research involving the recently deceased’—can fill a translational research gap while reducing harm to animals and living human subjects. It also creates new challenges for honouring the donor’s legacy, respecting the rights of donor loved ones, resource allocation and public health. As this research model gains traction, new empirical ethics questions must be answered to preserve public trust in all forms of tissue donation and (...) in the practice of medicine while respecting the legacy of the deceased and the rights of donor loved ones. This article suggests several topics for immediate investigation to understand the attitudes and experiences of researchers, clinical collaborators, donor loved ones and the public to ensure research involving the recently deceased advances ethically.

Here I describe an exercise that engages students and helps to introduce difficult concepts. The exercise can be used in a variety of courses, it can be tailored to help introduce future course concepts or readings, and it can be used in any level course; it engages both students with strong backgrounds in philosophy and students new to the discipline. The exercise can be used in courses covering ethics, social justice, philosophy of law, criminology, or epistemology. This paper explains the (...) exercise and highlights some ways the exercise can be modified. (shrink)

Systems thinking has emerged as a means of conceptualizing and addressing complex public health problems, thereby challenging more commonplace understanding of problems and corresponding solutions as straightforward explanations of cause and effect. Systems thinking tries to address the complexity of problems through qualitative and quantitative modeling based on a variety of systems theories, each with their own assumptions and, more importantly, implicit and unexamined values. To date, however, there has been little engagement between systems scientists and those working in bioethics (...) and public health ethics. The goal of this paper is to begin to consider what it might mean to combine systems thinking with public health ethics to solve public health challenges. We argue that there is a role for ethics in systems thinking in public health as a means of elucidating implicit assumptions and facilitating ethics debate and dialogue with key stakeholders.

Though we see the potential for benefits from the development of process-oriented approaches, we argue that it falls prey to many of the same critiques raised about the existing construct level of analysis. The construct-level approach will likely dominate motivation research until we develop computational models that are not only accurate, but also broadly usable.

Recurrent complex visual hallucinations (RCVH) represent a form of psychosis. It may be useful to compare RCVH to another form of psychosis, catatonia. Both include a long list of medical illnesses and have been examined using several different hypotheses. Catatonia has a variety of hypotheses, including neurocircuitry, neurochemistry, and an integrated neuropsychiatric hypothesis. This hypothesis for catatonia supports Collerton et al.'s Perception and Attention Deficit model (PAD) for RCVH.

Recent progress in artificial intelligence (AI) has drawn attention to the technology’s transformative potential, including what some see as its prospects for causing large-scale harm. We review two influential arguments purporting to show how AI could pose catastrophic risks. The first argument — the Problem of Power-Seeking — claims that, under certain assumptions, advanced AI systems are likely to engage in dangerous power-seeking behavior in pursuit of their goals. We review reasons for thinking that AI systems might seek power, that (...) they might obtain it, that this could lead to catastrophe, and that we might build and deploy such systems anyway. The second argument claims that the development of human-level AI will unlock rapid further progress, culminating in AI systems far more capable than any human — this is the Singularity Hypothesis. Power-seeking behavior on the part of such systems might be particularly dangerous. We discuss a variety of objections to both arguments and conclude by assessing the state of the debate. (shrink)

Here I describe a game that I use in my logic classes once we begin derivations. The game can help improve class dynamics, help struggling students recognizes they are not alone, open lines of communication between students, and help students of all levels prepare for exams. The game can provide struggling students with more practice with the fundamental rules of a logical system while also challenging students who excel at derivations. If students are struggling with particular rules or strategies in (...) the system, the game can be tailored to address them. I explain how the game has evolved since I started using it, highlighting the pedagogical benefits of the changes I have made, and (in the appendix) I provide examples of the handouts I distribute and a “checklist” to use before, during, and after the game.

Orality, generally defined as the preference for the spoken over the written word, is an academic discipline that has only recently received attention from the missiological community. The reality of widespread oral preference, also known as “secondary orality,” is no less true in Europe. In this article, the author focuses on the Romanian context. Using qualitative research gleaned from interviews with nine university-educated Romanians, patterns are developed that display how “secondary oral learners” choose to learn and retain new information. Specific (...) attention is given to theologically-related material. Six implications for theological education are advanced in the areas of (1) hermeneutics, (2) preaching, (3) evangelism, (4) discipleship, (5) church planting, and (6) leadership development. Paths forward for ministry in oral preference cultures like Romania are developed. The author concludes that the implementation of such suggestions could lead to more holistic ministry and is potentially transferrable to similar contexts. (shrink)

A. F. Norman has recently suggested that a hitherto overlooked passage in Suidas is a fragment from the history of Eunapius of Sardis. He is clearly correct in referring the passage to an incident at the siege of Maiozamalcha during the Persian campaign of the emperor Julian, but I am not so sure that he is right in ascribing it to Eunapius, or in the conclusions he draws from this ascription. I give in parallel columns the accounts of Ammianus Marcellinus, (...) Zosimus, and the passage from Suidas, together with a further version of the incident, unfortunately without names, from the pen of Libanius. (shrink)

Lawyers and the legal system have been much criticized in recent years. Despite popular perceptions, the legal system contains numerous mechanisms and rules designed to ensure fair results. This paper shows how the legal system tries to implement, in commercial transactions, the ethical principles of truthfulness and fairness. The Anglo-American development of Equity Courts is reviewed briefly. Several examples of the Law's enforcement of ethical principles are presented, in four different legal areas: Contracts, Securities, Goods, and Real Estate. The intent (...) here is to present an overview of the problem, with area-specific illustrations, rather than a comprehenisve examination of the cases in just one area. (shrink)

This paper is a critical reflection and response to the religious fideism of D. Z. Phillips, and especially to recent attempts to defend this fideism. Over the course of his career, Phillips argued for a number of interesting but quite dramatic theses about religious belief, including the claim that what is sometimes called the propositional nature of religious belief is frequently misunderstood by philosophers, and that this misunderstanding involves a distortion of what religious believers are doing when they say they (...) believe in God and engage in various religious practices. This paper explores these and other claims in the light of recent interesting attempts to defend them, especially in the work of Patrick Horn. I elaborate the distinction between the propositional and expressive dimensions of religious belief, and argue that Horn does not succeed in rescuing Phillips’s view from a number of serious philosophical objections, including the objection that theirs is a metaphorical interpretation of religion. I suggest also that Horn’s and Phillips’s fideistic versions of religious belief and religious phenomena may involve an element of self-deception, and would likely lead to people giving up their religious beliefs, or at least to their beliefs playing a decreasing role in their everyday lives.

Karl Popper (1902-1994) was one of the most influential philosophers of science of the 20th century. He made significant contributions to debates concerning general scientific methodology and theory choice, the demarcation of science from non-science, the nature of probability and quantum mechanics, and the methodology of the social sciences. His work is notable for its wide influence both within the philosophy of science, within science itself, and within a broader social context. Popper’s early work attempts to solve the problem of (...) demarcation and offer a clear criterion that distinguishes scientific theories from metaphysical or mythological claims. Popper’s falsificationist methodology holds that scientific theories are characterized by entailing predictions that future observations might reveal to be false. When theories are falsified by such observations, scientists can respond by revising the theory, or by rejecting the theory in favor of a rival or by maintaining the theory as is and changing an auxiliary hypothesis. In either case, however, this process must aim at the production of new, falsifiable predictions. While Popper recognizes that scientists can and do hold onto theories in the face of failed predictions when there are no predictively superior rivals to turn to. He holds that scientific practice is characterized by its continual effort to test theories against experience and make revisions based on the outcomes of these tests. By contrast, theories that are permanently immunized from falsification by the introduction of untestable ad hoc hypotheses can no longer be classified as scientific. Among other things, Popper argues that his falsificationist proposal allows for a solution of the problem of induction, since inductive reasoning plays no role in his account of theory choice. Along with his general proposals regarding falsification and scientific methodology, Popper is notable for his work on probability and quantum mechanics and on the methodology of the social sciences. Popper defends a propensity theory of probability, according to which probabilities are interpreted as objective, mind-independent properties of experimental setups. Popper then uses this theory to provide a realist interpretation of quantum mechanics, though its applicability goes beyond this specific case. With respect to the social sciences, Popper argued against the historicist attempt to formulate universal laws covering the whole of human history and instead argued in favor of methodological individualism and situational logic.

Dr. Strange sees Dr. Stephen Strange abandon his once-promising medical career to become a superhero with the ability to warp time and space, and to travel through various dimensions. In order to make this transition, he is required to abandon many of his previous assumptions about the way the world works and learn to see things in a new way. Importantly, this is not merely a matter of learning a few facts, or of mastering new techniques. Instead, Dr. Strange is (...) required to alter his conception of the basic nature of the world and of how he relates to it. In time, this change extends to his values as well, as Strange comes to embrace his role in safeguarding the human world from interdimensional threats. -/- It is tempting to interpret Dr. Strange’s experience as one that shows the limits of rational, scientific inquiry, or even of human knowledge more generally. However, in this essay, I’d like to explore a different interpretation: that Strange’s experience can most fruitfully be thought of as a scientific revolution, in which Strange moves from one way of carrying out scientific inquiry to a different, incompatible way of doing it. In order to do this, I’ll be exploring the work of philosopher and historian of science Thomas Kuhn, who wrote a book—The Structure of Scientific Revolutions--about just this topic. Among other things, Kuhn’s work introduced the highly useful (though commonly misunderstood) notion of a paradigm shift. -/- We’ll begin by exploring what Kuhn describes as normal science, which consists of applying a set of well-understood concepts and methods to problems of interest. This “puzzle-solving” aspect of science is exemplified by Strange’s early successes in medicine. During this stage, scientists have good reasons to avoid questioning the basic validity of their paradigm, and to instead blame any problems that arise on other factors, such as human error. (As fans will know, Strange is quite good at assigning blame in just this way.) A crisis only occurs when significant, serious anomalies have accrued, such as those that Strange encounters in the aftermath of his accident. Even then, however, the old paradigm will only be abandoned only if a new paradigm can be found. Again, Strange’s experience bears this out, as he is able to move on only when the Sorcerer Supreme introduces him to the Mystic Arts. -/- Along the way, we’ll consider what it means for a practice to count as a scientific paradigm, and why it’s not just “anything goes.” Among other things, a paradigm requires that practitioners agree on which problems are most important, which techniques are appropriate to which problems, and what exemplary models of successful work look like. The Mystic Arts of Strange’s world, unlike the pseudoscientific theories of our own, plausibly do quite well on these sorts of criteria. (shrink)

One hypothesis concerning the human dorsal anterior cingulate cortex (ACC) is that it functions, in part, to signal the occurrence of conflicts in information processing, thereby triggering compensatory adjustments in cognitive control. Since this idea was first proposed, a great deal of relevant empirical evidence has accrued. This evidence has largely corroborated the conflict-monitoring hypothesis, and some very recent work has provided striking new support for the theory. At the same time, other findings have posed specific challenges, especially concerning the (...) way the theory addresses the processing of errors. Recent research has also begun to shed light on the larger function of the ACC, suggesting some new possibilities concerning how conflict monitoring might fit into the cingulate's overall role in cognition and action.

This paper considers two related claims in the work of D. Z. Phillips: that commitment to God precludes a distinction between the commitment and the grounds for the commitment, and that belief and understanding are the same in religion. Both these claims motivate Phillips’s rejection of natural theology. I examine these claims by analyzing the notion of commitment, discussing what is involved in making a commitment to a worldview, why commitment is necessary at all in religion, levels of commitment, and (...) commitment and justification. I show that Phillips fails to distinguish between adopting a hypothesis, where justification would be germane, and committing to the hypothesis after one has adopted it, where justification is not so pressing. This failure fatally undermines his rejection of natural theology. (shrink)
