Inducing the rubber hand illusion (RHI) requires that participants look at an imitation hand while it is stroked in synchrony with their occluded biological hand. Previous explanations of the RHI have emphasized multisensory integration, and excluded higher cognitive functions. We investigated the relationship between the RHI and higher cognitive functions by experimentally testing task switch (as measured by switch cost) and mind wandering (as measured by SART score); we also included a questionnaire for attentional control that comprises two subscales, attention-shift (...) and attention-focus. To assess experience of RHI, the Botvinick and Cohen (1998) questionnaire was used and illusion onset time was recorded. Our results indicate that rapidity of onset reliably indicates illusion strength. Regression analysis revealed that participants evincing less switch cost and higher attention-shift scores had faster RHI onset times, and that those with higher attention-shift scores experienced the RHI more vividly. These results suggest that the multi-sensory hypothesis is not sufficient to explain the illusion: higher cognitive functions should be taken into account when explaining variation in the experience of ownership for the rubber hand.

Roommate relationships are fundamental to the social environment of many emerging adults. However, no validated, widely used, measure of roommate relationship quality exists for examining the impact of these relationships on individual functioning and health. In this report, we present preliminary evidence of the factor structure, concurrent validity, and construct validity of the Roommate Relationship Scale as a measure of roommate relationship quality using a sample of U.S. college students who participated in a multi-wave study. An exploratory factor analysis at (...) the first wave, and confirmatory factor analyses with independent samples of new participants at each of two subsequent waves showed stable factor loadings and adequate fit. Moreover, the scale demonstrated good fit and reliability in a longitudinal multilevel CFA framework. The RRS significantly positively correlated with relationship length, self-esteem, extraversion, agreeableness, and conscientiousness, and negatively correlated with symptoms of anxiety and avoidant attachment style, indicating concurrent validity of the scale with respect to these constructs. Consistent with findings from other relationship types, self-reported RRS scores decrease longitudinally, both across and between semesters of academic life, indicating construct validity of the scale. We conclude that the RRS is useful for evaluating roommate relationship quality among U.S. college students, and hopefully beyond. Further research should validate the scale’s utility in other, more diverse, populations and refine its underlying generating psychological process. (shrink)

Among Plato's works, the Statesman is usually seen as transitional between the Republic and the Laws. This book argues that the dialogue deserves a special place of its own. Whereas Plato is usually thought of as defending unchanging knowledge, Dr Lane demonstrates how, by placing change at the heart of political affairs, Plato reconceives the link between knowledge and authority. The statesman is shown to master the timing of affairs of state, and to use this expertise in managing the (...) conflict of opposed civic factions. To this political argument corresponds a methodological approach which is seen to rely not only on the familiar method of 'division', but equally on the unfamiliar centrality of the use of 'example'. The demonstration that method and politics are interrelated transforms our understanding of the Statesman and its fellow dialogues. (shrink)

Socrates wrote nothing; Plato's accounts of Socrates helped to establish western politics, ethics, and metaphysics. Both have played crucial and dramatically changing roles in western culture. In the last two centuries, the triumph of democracy has led many to side with the Athenians against a Socrates whom they were right to kill. Meanwhile the Cold War gave us polar images of Plato as both a dangerous totalitarian and an escapist intellectual. And visions of Plato have proliferated at the heart of (...) postmodern critiques of the very idea of metaphysics and politics. Plato's Progeny begins with an account of modern responses to the trial of Socrates and the controversial question of Socrates' relation to Plato. At its centre are two chapters exploring the idea of Platonic origins in and for philosophy, and of Platonic foundations for philosophical politics. Exploring unfamiliar as well as familiar invocations of Plato, Melissa Lane argues that twentieth-century ideological battles have obscured the importance of Socratic individualism, the nature of Platonic ethics, and the value of Platonic politics. Succinct and clearly written, this is an ideal guide for everyone interested in the way philosophers are still writing footnotes to Plato. (shrink)

"Plato's Statesman reconsiders many questions familiar to readers of the Republic: questions in political theory - such as the qualifications for the leadership of a state and the best from of constitution (politeia) - as well as questions of philosophical methodology and epistemology. Instead of the theory of Forms that is the centrepiece of the epistemology of the Republic, the emphasis here is on the dialectical practice of collection and division (diairesis), in whose service the interlocutors also deploy the ancillary (...) methods of myth and of models (paradeigmata). Plato here introduces the doctrine of due measure (to metrion) and a conception of statecraft (politikē) as an architectonic expertise that governs subordinate disciplines such as rhetoric and the military - doctrines later developed by Aristotle. Readers will find a sustained defence of the importance of expertise (technē or epistēmē) in the conduct of affairs of state, a robust (although not unqualified) defence of the rule of law, and an unsparing but nuanced critique of democratic government. The chapters in this volume provide a comprehensive and detailed philosophical engagement with the entirety of Plato's wide-ranging dialogue, with successive chapters devoted to the sections of the dialogue as it unfolds, and an introduction that places the dialogue in the context of Plato's philosophy as a whole. While not a commentary in the traditional sense, the volume engages with Plato's Statesman in its entirety" -- Publisher's description. (shrink)

It is argued that the Crito hinges on the relation between words and deeds. Socrates sets out a standard of agreement reached through persuasive argument or words. In this case the argument is deliberative: a general shared principle (do not do wrong) is juxtaposed to a particular minor premise (this act of escape is wrong) to reach a conclusion (do not escape). Crito baulks at the perception of the minor premise. At this juncture the Laws of Athens are introduced, who (...) set out a standard of agreement established instead by deeds. Both standards apply to Socrates, constituting the drama of the dialogue. (shrink)

Current UK legislation is impacting upon the feasibility and cost-effectiveness of medical record-based research aimed at benefiting the NHS and the public heath. Whereas previous commentators have focused on the Data Protection Act 1998, the Health and Social Care Act 2001 is the key legislation for public health researchers wishing to access medical records without written consent. The Act requires researchers to apply to the Patient Information Advisory Group for permission to access medical records without written permission. We present a (...) case study of the work required to obtain the necessary permissions from PIAG in order to conduct a large scale public health research project. In our experience it took eight months to receive permission to access basic identifying information on individuals registered at general practices, and a decision on whether we could access clinical information in medical records without consent took 18 months. Such delays pose near insurmountable difficulties to grant funded research, and in our case £560 000 of public and charitable money was spent on research staff while a large part of their work was prohibited until the third year of a three year grant. We conclude by arguing that many of the current problems could be avoided by returning PIAG’s responsibilities to research ethics committees, and by allowing “opt-out” consent for many public health research projects.

This study reports the results of a survey designed to assess the impact of education on the perceptions of ethical beliefs of students. The study examines the beliefs of students from selected colleges in an eastern university. The results indicate that beliefs which students perceive are required to succeed in the university differ among colleges. Business and economics students consistently perceive a greater need for unethical beliefs than students from other colleges.

This study reports the results of a survey designed to assess the impact of business education on the ethical beliefs of business students. The study examines the beliefs of graduate and undergraduate students about ethical behavior in educational settings. The investigation indicates that the behavior which students learn or perceive is required to succeed in business schools may run counter to the ethical sanctions of society and the business community.

To decode the function and molecular recognition of several recently discovered cytosine derivatives in the human genome – 5-hydroxymethylcytosine, 5-formylcytosine, and 5-carboxylcytosine – a detailed understanding of their effects on the structural, chemical, and biophysical properties of DNA is essential. Here, we review recent literature in this area, with particular emphasis on features that have been proposed to enable the specific recognition of modified cytosine bases by DNA-binding proteins. These include electronic factors, modulation of base-pair stability, flexibility, and radical changes (...) in duplex conformation. We explore these proposals and assess whether or not they are supported by current biophysical data. This analysis is focused primarily on the properties of epigenetically modified DNA itself, which provides a basis for discussion of the mechanisms of recognition by different proteins. 5-hydroxymethylcytosine, 5-formylcytosine, and 5-carboxylcytosine have recently been discovered in mammalian DNA and appear to have essential regulatory roles. Here, we summarize recent investigations into their effects on the structural, chemical, and biophysical properties of DNA, an understanding of which is essential to decoding their behavior in the genome.

Are the values of business students of today synchronized with the reality of the present business environment? Two hundred twenty-two business students rated the importance of twenty corporate goals. Moreover, the students rated the same goals as they perceived chief executive officers (CEOs) would have rated them. Significant differences were found between the two ratings, with students ranking social and employee-oriented goals as more important than they perceived CEOs would have.

The human tumour suppressor protein p53 is critical for regulation of the cell cycle on genotoxic insult. When DNA is damaged by radiation, chemicals or viral infection, cells respond rapidly by arresting the cell cycle. A G1 arrest requires the activity of wild‐type p53, as it is not observed in cells lacking functionally wild‐type protein, and at least some component of S phase and G2/M arrests is also thought to be p53‐dependent. p53 functions as a transcription factor which binds specific (...) DNA sequences, and recently major downstream targets have been identified, including p21Cip1 an inhibitor of the cell cycle kinases that also blocks the replicative but not the repair function of DNA polymerase δ auxiliary factor, PCNA. Current interest focuses on developing novel cancer therapies based on our knowledge of the activity of p53 and p21Cip1 in the cell cycle. (shrink)

Contemporary bioethics education has been developed predominately within Euro-American contexts, and now, other global regions are increasingly joining the field, leading to a richer global understanding. Nevertheless, many standard bioethics curriculum materials retain a narrow geographic focus. The purpose of this article is to use local cases from the Asia-Pacific region as examples for exploring questions such as ‘what makes a case or example truly local, and why?’, ‘what topics have we found to be best explained through local cases or (...) examples?’, and ‘how does one identify a relevant local case?’ Furthermore, we consider the global application of local cases to help extend the possible scope of the discussion, opening new avenues for the development of practical bioethics educational materials. We begin with a background description and discussion of why local cases enhance bioethics education, move to an overview of what is currently available and what is not for the region, and then outline a discussion of what it means to be local using example cases drawn from Hong Kong, Australia, Pakistan, and Malaysia. We are not creating a casebook but rather constructing by example a toolbox for designing active and dynamic learning cases using regional diversity as contextualised cases with generalised principles.

SUPERANNO A unique collection of photographs by WRA photographer Hikaru Iwasaki focuses on resettlement using photos of Japanese Americans following their release from WRA camps from 1943 to 1945. Author Lane Hirabayashi explores the use of photography in the WRA mission to encourage “loyal” Japanese Americans to return to society at large, and convince Euro-Americans this was safe. Hirabayashi also assesses the success of the WRA project, and the multiple uses of the photographs over time.

People are excused from moral blame for the harm they are said to have caused if they could not have done otherwise. Such excuses rely on causal explanations deriving mostly from social and biological sciences whose paradigms are probabilistic, disjunctive, and combine dispositional and circumstantial factors according to the variance accounted for by each type of factor. The more complete the explanation, the less choice the harm-doer seems to have and therefore the less moral blame is warranted. Thus, the biological (...) bases of people’s behaviour, their earlier socialization, and their prior choices reduce the scope and severity of moral blame — but have no effect on judgments of right and wrong. Fairness also requires a similar analysis of the behaviour of moral judges whose standards vary with their dispositions, social class, and culture. It follows that moral assessments are joint products of both ethics and the social and biological sciences, with neither group able to make fair moral assessments of people’s behaviour without help from the other.

Issues of methodology are central to the philosophy of moral progress. However, the idea that effective moral methodology, as well as being instrumental to progress, might also constitute progress has not been adequately explored. This paper will critically assess the merits of this idea – what I call ‘pure proceduralism about moral progress’ – taking Philip Kitcher's recent theory of ‘democratic contractualism’ (2021) as a test case. An epistemology of pure procedural moral progress will be sketched: namely, a naturalised epistemology (...) of paradigmatic instances of moral progress. Assuming an ideal procedure exists and has been at least approximately instantiated (an empirical claim), we learn about its form by studying paradigms of historical moral progress. From this epistemological method will be derived theoretical constraints on what can count as a theory of moral progress per se: it must capture the core semantic constraints on the term ‘moral progress,’ those features without which we would not recognise a change as moral progress. While this poses a tougher challenge for pure proceduralism than for more traditional approaches to moral methodology, it will be concluded that the potential of pure proceduralism as a viable metaethics of moral progress remains an exciting open question.

A promising argument for divine timelessness is that temporal life is possessed only moment by moment, which is incompatible with the existence of a perfect being.Since the argument is based on the experience of time’s passage, it cannot be circumvented by appeal to a tenseless theory of time.Neither can the argument be subverted by appeals to a temporal deity’s possession of a specious present of infinite duration.Nonetheless, because the argument concerns one’s experience of time’s passage rather than the objective reality (...) of temporal becoming itself, it is considerably weakened by the fact that an omniscient being possessing perfect memory and foreknowledge, need not find such experience to be an imperfection.

Does the seller of a house have to tell the buyer that the water is turned off twelve hours a day? Does the buyer of a great quantity of tobacco have to inform the seller that the military blockade of the local port, which had depressed tobacco sales and lowered prices, is about to end? Courts say yes in the first case, no in the second. How can we understand the difference in judgments? And what does it say about whether (...) the psychiatrist should disclose to his patient's girlfriend that the patient wants to kill her? Kim Lane Scheppele answers the question, Which secrets are legal secrets and what makes them so? She challenges the economic theory of law, which argues that judges decide cases in ways that maximize efficiency, and she shows that judges use equality as an important principle in their decisions. In the course of thinking about secrets, Scheppele also explores broader questions about judicial reasoning--how judges find meaning in legal texts and how they infuse every fact summary with the values of their legal culture. Finally, the specific insights about secrecy are shown to be consistent with a general moral theory of law that indicates what the content of law should be if the law is to be legitimate, a theory that sees legal justification as the opportunity to attract consent. This is more than a book about secrets. It is also a book about the limits of an economic view of law. Ultimately, it is a work in constructive legal theory, one that draws on moral philosophy, sociology, economics, and political theory to develop a new view of legal interpretation and legal morality.

For centuries, humans have contemplated the minds of gods. Research on religious cognition is spread across sub-disciplines, making it difficult to gain a complete understanding of how people reason about gods' minds. We integrate approaches from cognitive, developmental, and social psychology and neuroscience to illuminate the origins of religious cognition. First, we show that although adults explicitly discriminate supernatural minds from human minds, their implicit responses reveal far less discrimination. Next, we demonstrate that children's religious cognition often matches adults' implicit (...) responses, revealing anthropomorphic notions of God's mind. Together, data from children and adults suggest the intuitive nature of perceiving God's mind as human-like. We then propose three complementary explanations for why anthropomorphism persists in adulthood, suggesting that anthropomorphism may be an instance of the anchoring and adjustment heuristic; a reflection of early testimony; and/or an evolutionary byproduct.

Recent critiques of methodological naturalism (MN) claim that it fails by conflicting with Christian belief and being insufficiently humble.

The debate is a red herring. It only appears problematic because of confusion among its opponents about how scientists respond to experimental anomalies. We conclude by introducing our preferred (...) approach, Science‐Engaged Theology. (shrink)

Background Neuroimaging and lesion studies suggested that the dorsolateral prefrontal and posterior parietal cortices mediate visual metacognitive awareness. The causal evidence provided by non-invasive brain stimulation, however, is inconsistent. -/- Objective/hypothesis Here we revisit a major figure discrimination experiment adding a new Kanizsa figure task trying to resolve whether bilateral continuous theta-burst transcranial magnetic stimulation (cTBS) over these regions affects perceptual metacognition. Specifically, we tested whether subjective visibility ratings and/or metacognitive efficiency are lower when cTBS is applied to these two (...) regions in comparison to an active control region. -/- Methods A within-subjects design including three sessions spaced by one-week intervals was implemented. In each session, every participant was administered bilateral cTBS to either prefrontal, control or parietal cortices. Two concurrent tasks were performed, a real and an illusory figure task, stabilising objective performance with use of an adaptive staircase procedure. -/- Results When performing the replicated task, cTBS was found insufficient to disrupt neither visibility ratings nor metacognitive efficiency. However, with use of Kanizsa style illusory figures, cTBS over the dorsolateral prefrontal, but not over the posterior parietal cortex, was observed to significantly diminish metacognitive efficiency. -/- Conclusion(s) Real and illusory figure tasks demonstrated different cTBS effects. A possible explanation is the involvement of the prefrontal cortex in the creation of expectations, which is necessary for efficient metacognition. Failure to replicate previous findings for the real figure task, however, cannot be said to support, conclusively, the notion that these brain regions have a causal role in metacognitive awareness. This inconsistent finding may result from certain limitations of our study, thereby suggesting the need for yet further investigation. (shrink)

In this essay, I seek to demonstrate the interplay of philosophical voices – particularly, that of a platonist voice and a community-agreement-view voice – that drives Wittgenstein’s rule-following dialectic forward; and I argue that each voice succumbs to a particular form of dialectical oscillation that renders its response to the problem of rule-following philosophically inadequate. Finally, I suggest that, by seeing and taking stock of the dilemma in which these responses to the skeptical problem are caught, we can come to (...) appreciate Wittgenstein’s own view of what might constitute a proper a response to the so-called problem of rule-following. This view can be preliminarily characterized by saying that Wittgenstein’s aim is to dissolve the temptation to philosophically rebut the skeptical challenge posed by the rule-following dialectic, an aim he achieves by revealing the semantic emptiness of the apparent sentences that raise the skeptical problem.

Sydney Shoemaker, developing an idea of Wittgenstein’s, argues that we are immune to error through misidentification relative to the first-person pronoun. Although we might be liable to error when “I” (or its cognates) is used as an object, we are immune to error when “I” is used as a subject (as when one says, “I have a toothache”). Shoemaker claims that the relationship between “I” as-subject and the mental states of which it is introspectively aware is tautological: when, say, we (...) judge that “I feel pain,” we are tautologically aware that feels pain is instantiated and that it is instantiated in oneself. Moreover, he contends that this relationship holds not just for bodily sensations, but also for the sense of agency and for visual perception. But we deny that this relationship is tautological; instead, we treat Shoemaker’s principle (IEM) as a hypothesis. We then proceed to show that certain pathological states and experimentally-induced illusions can be adduced to show that IEM describes not a necessary relationship but a contingent relationship, one that sometimes fails to obtain. That we are not immune to error in the way Shoemaker describes has grave consequences for many aspects of his ideas concerning the first-person perspective. In the course of arguing that these empirical phenomena count against IEM, we also show that not only can the content of conscious experience be misrepresented, so too can the subject: that is, not only can the what of conscious experience be misrepresented, so too can the who.

This book offers a new interpretation of the metaphysics of Charles Peirce, the founder of pragmatism and one of America's greatest philosophers. Robert Lane begins by examining Peirce's basic realism, his belief in a world that is independent of how anyone believes it to be. Lane argues that this realism is the basis for Peirce's account of truth, according to which a true belief is one that would be settled by investigation and that also represents the real world. (...) He then explores Peirce's application of his Pragmatic Maxim to clarify the idea of reality, his two forms of idealism, and his realism about generality and vagueness. This rich study will provide readers with a clear understanding of Peirce's thoughts on reality and truth and how they intersect, and of his views on the relation between the mind and the external world.

In virtue of what does a sign have meaning? This is the question raised by Wittgenstein's rule-following considerations. Semantic dispositionalism is a (type of) theory that purports to answer this question. The present paper argues that semantic dispositionalism faces a heretofore unnoticed problem, one that ultimately comes down to its reliance on unanalyzed notions of repeated types of signs. In the context of responding to the rule-following paradox—and offering a putative solution to it—this amounts to simply assuming a solution to (...) the problem in one domain and using it to solve the same problem in another. Given, moreover, the level at which the rule-following paradox undercuts dispositionalism—the level of the notion of a sign's repetition—the objections made to the view also rule out causal/informational theories of meaning as well as communitarian/assertion-theoretic ones as potential solutions to the rule-following paradox.

This paper puts forward two claims about funding carbon capture and storage. The first claim is that there are moral justifications supporting strategic investment into CO2 storage from global and regional perspectives. One argument draws on the empirical evidence which suggests carbon capture and storage would play a significant role in a portfolio of global solutions to climate change; the other draws on Rawls' notion of legitimate expectations and Moellendorf's Anti-Poverty principle. The second claim is that where to pursue this (...) strategic investment poses a morally non-trivial problem, with considerations like near-term global distributive justice and undermining legitimate expectations favouring investing in developing regions, especially in Asia, and considerations like long-term climate impacts and best uses of resources favouring investing in the relatively wealthy regions that have the best prospects for successful storage development.

Children learn about the world from the testimony of other people, often coming to accept what they are told about a variety of unobservable and indeed counter-intuitive phenomena. However, research on children’s learning from testimony has paid limited attention to the foundations of that capacity. We ask whether those foundations can be observed in infancy. We review evidence from two areas of research: infants’ sensitivity to the emotional expressions of other people; and their capacity to understand the exchange of information (...) through non-verbal gestures and vocalization. We conclude that a grasp of the bi-directional exchange of information is present early in the second year. We discuss the implications for future research, especially across different cultural settings. (shrink)

Is the human mind uniquely nonphysical or even spiritual, such that divine intentions can meet physical realities? As scholars in science and religion have spent decades attempting to identify a 'causal joint' between God and the natural world, human consciousness has been often privileged as just such a locus of divine-human interaction. However, this intuitively dualistic move is both out of step with contemporary science and theologically insufficient. By discarding the God-nature model implied by contemporary noninterventionist divine action theories, one (...) is freed up to explore theological and metaphysical alternatives for understanding divine action in the mind. Sarah Lane Ritchie suggests that a theologically robust theistic naturalism offers a more compelling vision of divine action in the mind. By affirming that to be fully natural is to be involved with God's active presence, one may affirm divine action not only in the human mind, but throughout the natural world. (shrink)

For many years, Charles Peirce maintained that all senses of the modal terms "possible" and "necessary" can be defined in terms of "states of information." But in 1896, he was motivated by his work in set theory to criticize that account of modality, and in 1905 he characterized that criticism as a return "to the Aristotelian doctrine of a real possibility ... the great step that was needed to render pragmaticism an intelligible doctrine." But since Peirce was a realist about (...) modality before 1896, and since he continued defining "possibility" in terms of "states of information" after that date, it is not clear exactly what he changed his mind about. In this essay I explain what it was that Peirce changed his mind about and why, in retrospect, he viewed that change as a decisive step in the development of pragmaticism. (shrink)

Don Marquis has argued that abortion is immoral because it deprives the fetus of a "future like ours." But Marquis's argument fails by incorrectly assuming that a zygote and the late-term fetus with which it is physically continuous are numerically identical. In fact, the identity of a prebirth human (PBH) across gestation is indeterminate, such that it is determinately morally permissible to destroy an early-term PBH and determinately immoral to destroy a late-term PBH. Beginning at some indeterminate point during gestation (...) and ending at some indeterminate point later in gestation, destroying a PBH is neither determinately morally permissible nor determinately immoral.

The spring, summer, and fall 2006 editions of Critical Inquiry hosted a heated exchange between Ernesto Laclau and Slavoj Žižek regarding the proper definition of the Lacanian Real. Žižek claims "the Real is the inexorable abstract spectral logic of capital that determines what goes on in social reality". In response, Laclau states that Žižek's "spectral logic of capital" is a gross distortion of Lacanian theory: "The Real is not a specifiable object endowed with laws of movement on its own but, (...) on the contrary, something that only exists and shows itself through its disruptive effects within the Symbolic". Laclau's formulation of the Real, however, forecloses the possibility of... (shrink)

The question of whether or not God exists is profoundly fascinating and important. Now two articulate spokesmen--one a Christian, the other an atheist--duel over God's existence in an illuminating battle of ideas. In God? A Debate between a Christian and an Atheist, William Lane Craig and Walter Sinnott-Armstrong bring to the printed page two debates they held before live audiences, preserving all the wit, clarity, and immediacy of their public exchanges. Avoiding overly esoteric arguments, they directly address issues such (...) as religious experience, the Bible, evil, eternity, the origin of the universe, design, and the supposed connection between morality and the existence of God. Employing sharp and humorous arguments, each philosopher strikes quickly to the heart of his opponent's case. For example, Craig claims that we must believe in God in order to explain objective moral values, such as why rape is wrong. Sinnott-Armstrong responds that what makes rape wrong is the harm to victims of rape, so rape is immoral even if there is no God. By assuming a traditional concept of God in their discussion, the authors ensure that they are truly addressing each other's viewpoints and engaging in a disagreement over a unified issue. The book is composed of six chapters that alternate between Craig and Sinnott-Armstrong, so that each separate point can be discussed as it arises. Ideal for courses in the philosophy of religion and introduction to philosophy, this lively and direct dialogue will stimulate students and anyone interested in the existence of God, regardless of whether or not they believe in God.
