One interpretation of the conditional If P then Q is as saying that the probability of Q given P is high. This is an interpretation suggested by Adams (1966) and pursued more recently by Edgington (1995). Of course, this probabilistic conditional is nonmonotonic, that is, if the probability of Q given P is high, and R implies P, it need not follow that the probability of Q given R is high. If we were confident of concluding Q from the fact (...) that we knew P, and we have stronger information R, we can no longer be confident of Q. We show nonetheless that usually we would still be justified in concluding Q from R. In other words, probabilistic conditionals are mostly monotonic. (shrink)

_ Source: _Page Count 20 Research by Graham and Haidt suggests that beliefs, rituals, and other social aspects of religion establish moral communities. As such, they suggest religion is most strongly associated with the group-focused “binding” moral foundations of ingroup/loyalty, authority/respect, and purity/sanctity. Two studies tested this hypothesis, investigating the role of political orientation in these relationships. These studies supported our hypothesis that general religiosity is positively associated with each of the group-focused moral foundations, even when controlling for the role (...) of political orientation. Further, we find religious and political orientations interact such that low-religious political liberals are least likely to endorse group-focused moral intuitions. Results are discussed in a moral foundations framework and consider the role of religiosity’s association with political orientation and group-focused moral foundations. (shrink)

The earlier volume in this series dealt with two religions of Indian origin, namely, Buddhism and Jainism. The Indian religious scene, however, is characterized by not only religions which originated in India but also by religions which entered India from outside India and made their home here. Thus religious life in India has been enlivened throughout its history by the presence of religions of foreign origin on its soil almost from the very time they came into existence. This volume covers (...) three such religions—Zoraoastrianism, Judaism, and Islam. In the case of Zoraostianism, even its very beginnings are intertwined with India, as Zoroastrianism reformed a preexisting religion which had strong links to the Vedic heritage of India. This relationship took on a new dimension when a Zoroastrian community, fearing persecution in Persia after its Arab conquest, sought shelter in western India and ultimately went on to produce India’s pioneering nationalist in the figure of Dadabhai Naoroji ( 1825-1917), also known as the Grand Old Man of India. Jews found refuge in south India after the destruction of the Temple by the Romans in 70 C.E. and have remained a part of the Indian religious scene since then, some even returning to Israel after it was founded in 1948. Islam arrived in Kerala as soon as it was founded and one of the earliest mosques in the history of Islam is found in India. Islam differs from the previously mentioned religions inasmuch as it went on to gain political hegemony over parts of the country for considerable periods of time, which meant that its impact on the religious life of the subcontinent has been greater compared to the other religions. It has also meant that Islam has existed in a religiously plural environment in India for a longer period than elsewhere in the world so that not only has Islam left a mark on India, India has also left its mark on it. Indeed all the three religions covered in this volume share this dual feature, that they have profoundly influenced Indian religious life and have also in turn been profoundly influenced by their presence in India.

This book highlights some of the most pressing safety, ethical, legal and societal issues related to the diverse contexts in which robotic technologies apply. Focusing on the essential concept of well-being, it addresses topics that are fundamental not only for research, but also for industry and end-users, discussing the challenges in a wide variety of applications, including domestic robots, autonomous manufacturing, personal care robots and drones.

We report the identification of a recurrent, 520-kb 16p12.1 microdeletion associated with childhood developmental delay. The microdeletion was detected in 20 of 11,873 cases compared with 2 of 8,540 controls and replicated in a second series of 22 of 9,254 cases compared with 6 of 6,299 controls. Most deletions were inherited, with carrier parents likely to manifest neuropsychiatric phenotypes compared to non-carrier parents. Probands were more likely to carry an additional large copy-number variant when compared to matched controls. The clinical (...) features of individuals with two mutations were distinct from and/or more severe than those of individuals carrying only the co-occurring mutation. Our data support a two-hit model in which the 16p12.1 microdeletion both predisposes to neuropsychiatric phenotypes as a single event and exacerbates neurodevelopmental phenotypes in association with other large deletions or duplications. Analysis of other microdeletions with variable expressivity indicates that this two-hit model might be more generally applicable to neuropsychiatric disease. © 2010 Nature America, Inc.

Blair articulates a concept of argument that suggests, as he puts it, that argument is a normative concept (Blair, Informal Logic 24:137–151, 2004, p. 190). Put roughly, the idea is that a collection of propositions doesn’t constitute an argument unless some taken together constitute a reason for the remaining proposition and thereby support it enough to provide at least prima facie justification for it (Blair, in: Blair, Johnson, Hansen, Tindale (eds) Informal Logic at 25, Proceedings of the 25th anniversary (...) conference, Ontario Society for the Study of Argumentation, 2003, p.173). My primary task in this paper is to advance an understanding of the illative unit of argument and the reasons associated with it that provides an intuition pump for a normative concept of argument. My aim is to advance a positive consideration in favor of a normative concept of argument that motivates its further development. I take the normative concept of argument I defend here to be in the same ballpark as the one Blair characterizes. (shrink)

This article argues that Virgil includes an allusion to the fourth-century censor Appius Claudius Caecus in Book 8 of the Aeneid. Three pieces of evidence point to this allusion: (1) wordplay, especially the near echo of ‘Caecus’ in ‘Cacus’; (2) semantic associations between Cacus and darkness; and (3) repeated references to sight and Cacus’ eyes. By invoking the memory of Appius, whose blinding in 312 b.c.e. allegedly came at the hands of Hercules as punishment for transferring control of the god's (...) rites at the Ara Maxima to the state, Virgil underscores the importance of properly observing religious rituals. This aligns with Evander's original intent with the Hercules–Cacus story to prove to Aeneas and the Trojans that the Arcadians’ religious practices are no uana superstitio (8.187). (shrink)

Westworld is a television series on HBO (2016–present), based on a movie of the same name by Michael Crichton. The plot of the show is wide-reaching. The first season shows us an adult theme park where android “hosts” serve the wealthy “guests.” Seasons two and three show the attempt of the hosts to escape this servitude, and then, in a twist, help humans do the same outside of the parks. This chapter links all three seasons of Westworld to theories of (...) colonization. First, it explores the types of colonialism as they pertain to Westworld. Then it looks at the various scopes of colonization in Westworld – the colonization of space, time, and psychic space. Next, it explores the psychology of colonizers and the colonized as it pertains to the show. Lastly, it explores possible forms of liberation from colonization that the show has to offer. (shrink)

This is a well-behaved concept in Newtonian physics. But a center of gravity is not an atom or a subatomic particle or any other physical item in the world. It has no mass; it has no color; it has no physical properties at all, except for spatio-temporal location. It is a fine example of what Hans Reichenbach would call an abstractum. It is a purely abstract object. It is, if you like , a theorist's fiction. It is not one of (...) the real things in the universe in addition to the atoms. But it is a fiction that has nicely defined, well delineated and well behaved role within physics. (shrink)

Research in the neurosciences continues to provide evidence that sleep plays a role in the processes of learning and memory. There is less of a consensus, however, regarding the precise stages of memory development during which sleep is considered a requirement, simply favorable, or not important. This article begins with an overview of recent studies regarding sleep and learning, predominantly in the procedural memory domain, and is measured against our current understanding of the mechanisms that govern memory formation. Based on (...) these considerations, I offer a new neurocognitive framework of procedural learning, consisting first of acquisition, followed by two specific stages of consolidation, one involving a process of stabilization, the other involving enhancement, whereby delayed learning occurs. Psychophysiological evidence indicates that initial acquisition does not rely fundamentally on sleep. This also appears to be true for the stabilization phase of consolidation, with durable representations, resistant to interference, clearly developing in a successful manner during time awake (or just time, per se). In contrast, the consolidation stage, resulting in additional/enhanced learning in the absence of further rehearsal, does appear to rely on the process of sleep, with evidence for specific sleep-stage dependencies across the procedural domain. Evaluations at a molecular, cellular, and systems level currently offer several sleep specific candidates that could play a role in sleep-dependent learning. These include the upregulation of select plasticity-associated genes, increased protein synthesis, changes in neurotransmitter concentration, and specific electrical events in neuronal networks that modulate synaptic potentiation. Key Words: consolidation; enhancement; learning; memory; plasticity; sleep; stabilization. (shrink)

Background Since 2010 the People’s Republic of China has been engaged in an effort to reform its system of organ transplantation by developing a voluntary organ donation and allocation infrastructure. This has required a shift in the procurement of organs sourced from China’s prison and security apparatus to hospital-based voluntary donors declared dead by neurological and/or circulatory criteria. Chinese officials announced that from January 1, 2015, hospital-based donors would be the sole source of organs. This paper examines the availability, transparency, (...) integrity, and consistency of China’s official transplant data. Methods Forensic statistical methods were used to examine key deceased organ donation datasets from 2010 to 2018. Two central-level datasets — published by the China Organ Transplant Response System and the Red Cross Society of China — are tested for evidence of manipulation, including conformance to simple mathematical formulae, arbitrary internal ratios, the presence of anomalous data artefacts, and cross-consistency. Provincial-level data in five regions are tested for coherence, consistency, and plausibility, and individual hospital data in those provinces are examined for consistency with provincial-level data. Results COTRS data conforms almost precisely to a mathematical formula while Central Red Cross data mirrors it, albeit imperfectly. The analysis of both datasets suggests human-directed data manufacture and manipulation. Contradictory, implausible, or anomalous data artefacts were found in five provincial datasets, suggesting that these data may have been manipulated to enforce conformity with central quotas. A number of the distinctive features of China’s current organ procurement and allocation system are discussed, including apparent misclassification of nonvoluntary donors as voluntary. Conclusion A variety of evidence points to what the authors believe can only be plausibly explained by systematic falsification and manipulation of official organ transplant datasets in China. Some apparently nonvoluntary donors also appear to be misclassified as voluntary. This takes place alongside genuine voluntary organ transplant activity, which is often incentivized by large cash payments. These findings are relevant for international interactions with China’s organ transplantation system. (shrink)

"Over three years of study and fellowship, sixteen Muslim, Jewish, and Christian scholars sought to answer one question: “Do our three scriptures unite or divide us?” They offer their answers in this book: sixteen essays on how certain ways of reading scripture may draw us apart and other ways may draw us, together, into the source that each tradition calls peace. Reading scriptural sources in the classical and medieval traditions, the authors examine how each tradition addresses the “other” within its (...) tradition and without, how all three traditions attend to poverty as a societal and spiritual condition, and what it means to read scripture while facing the challenges of modernity. Ochs and Johnson have assembled a unique approach to inter-religious scholarship and a rare look at scriptural study as a pathway to peace. “Scriptural reasoning, the growing practice of Jews, Christians, and Muslims reading their scriptures together, makes good academic and common sense in a time of crisis. This ground-breaking book, the outcome of an imaginative 3-year experiment by the Princeton Center of Theological Inquiry, shows scholars and thinkers of the Abrahamic traditions going deeper into the traditions and into their contemporary situation. The result is something new, wise, and relevant… full of promise for the future. Where else can one find testimonies to Jews, Christians, and Muslims coming together not only in study, thinking, and wisdom-seeking but also in play, joy, and friendship?”--David F.

RESUMEN Una vez que el foco de la reflexión pasa de las teorías ideales a la aplicación de la justicia social, centrada en las instituciones de las sociedades democráticas, se requiere prestar especial atención a los estilos de vida. Estos tienen una alta incidencia en cómo la justicia es realizada y afectan tanto a la desigualdad económica como a la disponibilidad de los recursos naturales. En nuestras sociedades es posible establecer restricciones a los estilos de vida, especialmente en aquellos casos (...) en que, por el efecto de algunas dinámicas sociales, aquellos se desacoplan de las concepciones del bien. Se defiende que, en tales casos, la base normativa que permite exigir el respeto a los estilos de vida se disuelve y por ello es posible justificar su restricción. ABSTRACT Now that the focus of reflection has shifted from ideal theories to the application of social justice, centered on the institutions of democratic societies, it is necessary to pay special attention to lifestyles, since they not only influence the realization of justice, but also have an effect on economic inequality and the availability of natural resources. In our societies, it is possible to place restrictions on lifestyles, especially in those cases in which, influenced by certain social dynamics, they disengage from conceptions of the good. The article argues that, in those cases, the normative base grounding the demand that lifestyles be respected is dissolved, thus justifying their restriction. (shrink)

Is there such a thing as information justice? In this paper, I argue that the current state of the information economy, particularly as it regards information and computing technology (ICT), is unjust, conferring power disproportionately on the information-wealthy at great expense to the information-poor. As ICT becomes the primary method for accessing and manipulating information, it ought to be treated as a foundational layer of the information economy. I argue that by maximizing the liberties (freedom to use, freedom to distribute, (...) freedom to modify, and so on) associated with certain computer software, an incentives-rich and stable environment can be established in ICT that will foster development of the information economy among the information poor. I suggest that the now-mature Free and Open Source Software paradigm, which has already produced widely-used enterprise-class applications, can be harnessed in support of these ends. (shrink)

Rising income inequality was a major factor in the surge of household debt that brought on the financial crash and Great Recession. Other studies have identified rising household debt as a cause of the crash but not income inequality as a cause of the rising debt. Here the unusual rise in household debt post 1995 is documented. Econometric evidence links rising income inequality to the rise of household debt. Consumer expenditure data shows that prices of major necessities —shelter, healthcare and (...) education—rose faster than inflation as demand by high-income households surged. In order to maintain their consumption of such necessities, lower-income households resorted to massive borrowing. Their rising debt precipitated the financial crash and Great Recession. That link was overlooked by mainstream economists because they adhere to a theory of household consumption that posits no role for income inequality. (shrink)

This article argues that integrating philosophy courses and the first-year experience can address the problem of attracting students to the philosophy major and make philosophical material more accessible and engaging. Through a reflection on teaching a first-year honors seminar on the topic of meaning in life, I show how we can use the philosophical tradition to help students with the transition into the university environment and, in the process, give them a sense of the value of philosophy as a tool (...) to think through and evaluate their current experiences. The article demonstrates the value of philosophy to first-year students and shows how philosophy faculty and departments are well-suited to contribute to first-year programming at their institutions. Furthermore, it shows how addressing these issues can help departments recruit students into their major and minors while also sparking a genuine interest in philosophical inquiry. (shrink)

Most organisms display oscillations of approximately 24 hours in their physiology. In higher organisms, these circadian oscillations in biochemical and physiological processes ultimately control complex behavioral rhythms that allow an organism to thrive in its natural habitat. Daily and seasonal light cycles are mainly responsible for keeping the circadian system properly aligned with the environment. The molecular mechanisms responsible for the control of the circadian clock have been explored in a number of systems. Interestingly, the circadian oscillations that are responsive (...) to environmental stimuli are present very early during development. This review focuses on the advantages of using the zebrafish to study the development of the vertebrate circadian system and light‐dependent signaling to the clock.

Jurors customarily do their work with very little by way of instruction from the court, other than about the law. This suggests that they enter the jury room with the relevant cognitive and interactional tools at the ready, drawn from everyday life. This paper focuses on a specific conversational device jurors use to do their work: conditional-contrastive inculpations, whereby the defendant’s actions are compared unfavorably to what a normal, innocent person would have done, with the implication that the discrepancy indicates (...) guilt. We examine the logic, variants, sequential precursors, and immediate consequences of this phenomenon in two real-life American criminal juries deliberating the same charges. This study offers a rare glimpse into the operation of real juries, and specifically the way in which they appropriate a practice from ordinary conversation in order to perform the unordinary work demanded of them by the legal system.

Chapter 1 reconstructs Gadamer's fundamental philosophical task. The task is the problem of certainty, which is the problem of responding in some way or another to reasons that seem to show that we need, but cannot complete, the justificationalist project. Justificationalism is the view that we need a special philosophical of all human knowledge all at once. Chapter 2 argues that Hegel and Heidegger both try to solve the problem of certainty by transforming the realist conception of truth on which (...) it depends. Chapters 3 and 4 argue that Gadamer provides the resources for a different response. By exploiting similarities between Gadamer's account of understanding and externalism in analytic epistemology, I argue that there is a possible position, hermeneutic externalism, which is based on Gadamer's concept of authority. Chapter 5 tries to show how hermeneutic externalism finally provides an answer to the problem of certainty. The conclusion that I would like to draw from the whole of this work is that Gadamer is a realist and an externalist, in the sense that those views represent what he should think. He should embrace externalism and realism because they best represent his genuine insights and they best address the philosophical task as he conceives it. (shrink)

Descriptions of emotion incidents were extracted from classic American novels of the Romantic, Victorian, and Modern Periods. These descriptions were then rated by respondents on scales relevant to attribution of responsibility for emotions. It was found that ratings of the emotion descriptions differed across the three literary periods, with descriptions from the Romantic Period being rated most intense and most appropriate, descriptions from the Victorian Period as least intense, and descriptions from the Modern Period as least appropriate. In addition, it (...) was found that the contemporary American folk theory of attribution of responsibility for emotions might be characterised as being based on perceived intensity of emotions, the social appropriateness of emotions, and the degree to which persons other than the emoter might be said to be responsible for the emoter's emotion. These findings are supportive of a growing appreciation in the emotion literature for culturally and historically relative approaches to emotion research. (shrink)

J.L. Austin described speech acts as utterances which are themselves actions, and not simply descriptions of actions or states of affairs. It is suggested that emotions are also actions, and not simply results of actions. Emotions may be conceived as attunements in the phenomenological tradition, as means of experiencing the world. Understood as attunements, emotions are actions in the sense that they do not simply result from appraisal processes or social constraints, but are themselves our engagements with the world. Three (...) insights into the nature of emotion achieved through the comparison of speech acts and emotions are discussed: emotions may best be studied as acts, and not as elements such as cognitive appraisals, characteristic feeling states, or states of physiological arousal which often accompany emotions; the study of emotions as acts may best be viewed as an exercise in uncovering rather than discovering knowledge; and emotions are commitments to world views and, as such, are susceptible to moral evaluation.

Although cognitively oriented theories of emotion are now dominant in the psychological study of emotion, there remain issues upon which these theories do not agree. Central among these are questions regarding the minimal cognitive processes necessary to have an emotion. A potentially productive approach to such questions is the study of the relation of cognitive development and the development of emotions in infants. Such an approach was featured in ancient philosophical and psychological treatises, some of which formed the very foundations (...) of later cognitive theories. However, the recent literature has been nearly indifferent to just these foundations. Ancient commentators, especially Aristotle and the Stoic and Epicurean philosophers, understood emotions as fundamentally sociomoral constructs. Owing to a lack of socialisation and moral understanding, infants are not fully capable of experiencing emotions as they are typically understood. Contemporary work in the area of emotion, including that of Michael Lewis, as well as work in other emotion-related areas, is shown to address only inadequately the sociomoral components of emotion and thus to address only inadequately the emotion-cognition relationship.

In a fictional conversation designed to appeal to both working teachers and social philosophers, three educators take up the question of whether critical thinking itself can, or should, be taught independently of an explicit consideration of issues related to social justice. One, a thoughtful but somewhat traditional Enlightenment rationalist, sees critical thinking as a neutral set of skills and dispositions, essentially unrelated to the conclusions of morality, problems of social organization, or the content of any particular academic discipline. A second (...) interlocutor, steeped in “critical” pedagogy of Paulo Freire, insists that the problem is the pose of neutrality itself. On this view, all honest and effective approaches to teaching must confront the hegemony of unjust relationships, institutions, and conceptual schemes. The third character attempts to resolve the tension between these two opposed camps. (shrink)

We consider three types of objection: first, that the difficulty of having adequate knowledge renders the stock “ticking bomb” scenario such a low-probability hypothetical as to present no realistic threat to a policy banning all torture; second, that empirically the information gleaned from torture is so unlikely to be reliable that it could not justify the moral (...) risk; and third, that sanctioning torture, even if only under the most extreme circumstances, would generate a ‘culture of torture,’ hence undermining fragile advances in international human rights rooted in unwavering commitment to human dignity.

Inferences about spatial, temporal, and other relations are ubiquitous. This article presents a novel model-based theory of such reasoning. The theory depends on 5 principles. The structure of mental models is iconic as far as possible. The logical consequences of relations emerge from models constructed from the meanings of the relations and from knowledge. Individuals tend to construct only a single, typical model. They spontaneously develop their own strategies for relational reasoning. Regardless of strategy, the difficulty of an inference depends (...) on the process of integration of the information from separate premises, the number of entities that have to be integrated to form a model, and the depth of the relation. The article describes computer implementations of the theory and presents experimental results corroborating its main principle. (shrink)

Given a basic conditional of the form, If A then C, individuals usually list three cases as possible: A and C, not‐A and not‐C, not‐A and C. This result corroborates the theory of mental models. By contrast, individuals often judge that the conditional is true only in the case of A and C, and that cases of not‐A are irrelevant to its truth or falsity. This result corroborates other theories of conditionals. To resolve the discrepancy, we devised two new tasks: (...) the “collective” truth task, in which participants judged whether sets of assertions about a specific individual, such as: If A then C, not‐A, C, could all be true at the same time; and one in which participants judged the truth of conditional predictions about specific future events. The results consistently matched the three possibilities, thereby corroborating the model theory. They also showed a massive violation of the probability calculus in estimates of the probabilities of the four cases in the partition of conditionals (A and C, A and not‐C, not‐A and C, and not‐A and not‐C), which summed to over 200%.
