By 20 October 2021, the U.S. Food and Drug Administration (FDA) had amended its Emergency Use Authorizations for immunocompetent adults who previously received the Pfizer-BioNTech, Moderna, or Johnson & Johnson COVID-19 vaccines. For the 2-dose Pfizer-BioNTech and Moderna vaccines, the FDA permitted a single booster dose for adults aged 65 years or older and adults aged 18 to 64 years at high-risk for severe COVID-19 or at high risk for occupational or institutional COVID-19 exposure. For the single-dose Johnson & Johnson (...) vaccine, the FDA permitted a single booster dose for all adults aged 18 or older. These eligibility schemes were endorsed by the Centers for Disease Control and Prevention shortly after FDA approval. (shrink)

Traditionally, the problem of evil, in its various formulations, has been one of the strongest objections against perfect being theism. In the voluminous literature on this problem, the motif of evil has usually been discussed with respect to human flourishing. In recent decades more focused attention has been paid to animal suffering and the philosophical problems that such suffering poses for perfect being theists. However, this growing body of literature, in Anglo-American philosophical milieus, is largely aimed at sketching a specifically (...) Christian or Christianity-inflected theodicy that would reconcile animal suffering with the existence of an omni-God. In contrast, there are few, if any, systematic attempts to put forth a Hindu theodicy that aims to offer morally justifiable reasons that God has for allowing animal suffering. In this article, we address this scholarly lacuna by illustrating how a Hindu perfect being theist might respond to the problem of animal suffering. (shrink)

Necessity and sufficiency are the building blocks of all successful explanations. Yet despite their importance, these notions have been conceptually underdeveloped and inconsistently applied in explainable artificial intelligence (XAI), a fast-growing research area that is so far lacking in firm theoretical foundations. Building on work in logic, probability, and causality, we establish the central role of necessity and sufficiency in XAI, unifying seemingly disparate methods in a single formal framework. We provide a sound and complete algorithm for computing explanatory factors (...) with respect to a given context, and demonstrate its flexibility and competitive performance against state of the art alternatives on various tasks.

PurposeA significant volume of philosophical literature produced by Indian academic philosophers in the first half of the twentieth century can be placed under the rubric of ‘Śaṁkara and X’, where X is Hegel, or a German or a British philosopher who had commented on, elaborated or critiqued the Hegelian system. We will explore in this essay the philosophical significance of Hegel-influenced systems as an intellectual conduit for these Indo-European conceptual encounters, and highlight how for some Indian philosophers the British variations (...) on Hegelian systems were both a point of entry into debates over ‘idealism’ and ‘realism’ in contemporary European philosophy and an occasion for defending Advaita against the charge of propounding a doctrine of world illusionism.MethodologyOur study of the philosophical enquiries of A.C. Mukerji, P.T. Raju, and S.N.L. Shrivastava indicates that they developed distinctive styles of engaging with Hegelian idealisms as they reconfigured certain aspects of the classical Advaita of Śaṁkara through contemporary vocabulary.Result and ConclusionThese appropriations of Hegelian idioms can be placed under three overlapping styles: Mukerji was partly involved in locating Advaita in an intermediate conceptual space between, on the one hand, Kantian agnosticism and, on the other hand, Hegelian absolutism; Raju and Shrivastava presented Advaitic thought as the fulfilment of certain insights of Hegel and F.H. Bradley; and the interrogations of Hegel’s ‘idealism’ provided several Indian academic philosophers with a hermeneutic opportunity to revisit the vexed question of whether the ‘idealism’ of Śaṁkara reduces the phenomenal world, structured by māyā, to a bundle of ideas.

We propose a new relevance sensitive model for representing and revising belief structures, which relies on a notion of partial language splitting and tolerates some amount of inconsistency while retaining classical logic. The model preserves an agent's ability to answer queries in a coherent way using Belnap's four-valued logic. Axioms analogous to the AGM axioms hold for this new model. The distinction between implicit and explicit beliefs is represented and psychologically plausible, computationally tractable procedures for query answering and belief..

A survey of the key arguments that have been developed for and against the rationality of belief in reincarnation shows that often the central dispute is not over what the ‘data’ are but how to assess the ‘data’ from specific metaphysical–hermeneutical horizons. By examining some of these arguments formulated by Hindu thinkers as well as their critiques – from the perspectives of metaphysical naturalism and Christian theology – we argue that one of the reasons why these debates remain intractable is (...) that the ‘theory’ is underdetermined by the ‘data’, so that more than one set of the latter can be regarded as adequate explanations of the former.

While Gandhi and Ambedkar hold similar standpoints on the relation between religious orderings of the world and shapes of social existence, they sharply diverge, on certain occasions, regarding the question of what the crucial terms ‘caste’ and varņa refer to, so that they often seem to be talking past each other. Gandhi sought to cut through various traditional forms of Hindu socio-religious practices and develop a Hinduism which is grounded in the values of universal peace, love and benevolence. Ambedkar too (...) rejected aspects of familiar historical varieties of Buddhism and configured a new vehicle whose goals were to be more specifically material than spiritual. However, while both Gandhi and Ambedkar thus sought to uncover the revitalizing impulses of religious ideals, they operated with different imaginations of the type of polity that would emerge from this social reconstruction. For Gandhi, the reinvigorated socio-religious whole would be structured by an ideal notion of varņa in which there would b... (shrink)

Subset Spaces were introduced by L. Moss and R. Parikh in [8]. These spaces model the reasoning about knowledge of changing states.In [2] a kind of subset space called intersection space was considered and the question about the existence of a set of axioms that is complete for the logic of intersection spaces was addressed. In [9] the first author introduced the class of directed spaces and proved that any set of axioms for directed frames also characterizes intersection spaces.We (...) give here a complete axiomatization for directed spaces. We also show that it is not possible to reduce this set of axioms to a finite set. (shrink)

The moral and ethical challenges of living in community pertain not only to the intersection of human beings one with another, but also our interactions with our machine creations. This article explores the philosophical and theological framework for reasoning and decision-making through the lens of science fiction, religion, and artificial intelligence (both real and imagined). In comparing the programming of autonomous machines with human ethical deliberation, we discover that both depend on a concrete ordering of priorities derived from a clearly (...) defined value system.

A study of Hindu engagements with violence which have been structured by scriptural themes reveals that violence has been regulated, enacted, resisted, negated or denied in complex ways. Disputes based on Vedic orthodoxy were channeled, in classical India, through the mythical frameworks of gods clashing with demons, and later in the medieval centuries this template was extended to the Muslim foreigners who threatened the Brahmanical socio-religious orders. In the modern period, the electoral mechanisms of colonial modernity spurred Hindu anxieties about (...) a weakened nation which would die out in the face of Muslim solidarity, and various Hindu organizations began to increasingly draw on motifs from the Vedas, Bhagavad-gītā, and other texts to speak of a martial Hindu nation. These two moments—the articulation of the boundaries of the robust Hindu nation and the projection of the Muslim as the enemy lurking at the gates—have been integral to the shaping of Hindu cultural nationalism by several key thinkers and political activists. Thus, the forms of violence associated with Hindu universes should be placed within their dynamic socio-historical contexts where Hindus have interpreted, engaged with, and acted on a range of scriptural texts both to generate violent solidarities and to speak of peace. A study of these phenomena alongside some Christian theological attempts to legitimize, valorize or transcend violence from within scriptural horizons points to the complex conceptual terrain encompassed by the conjunction in “religion and violence.”.

This article explores some of the understandings of “science” that are often employed in the literature on “science and Eastern religions.” These understandings crucially shape the raging debates between the avid proponents and the keen detractors of the thesis that Eastern forms of spirituality are uniquely able to subsume the sciences into their metaphysical–axiological horizons. More specifically, the author discusses some of the proposed relations between “science” and “Eastern religions” by highlighting three themes: the relation between science and metaphysics, the (...) relation between science and experience, and the European origins of science. The analysis of these relations requires a methodological inquiry into some of the culturally freighted valences of “science,” “metaphysics,” and “experience.”. (shrink)

We investigate the semantics of messages, and argue that the meaning ofa message is naturally and usefully given in terms of how it affects theknowledge of the agents involved in the communication. We note thatthis semantics depends on the protocol used by the agents, and thus not only the message itself, but also the protocol appears as a parameter in the meaning. Understanding this dependence allows us to give formal explanations of a wide variety of notions including language dependence, implicature, (...) and the amount of information in a message.

We shall examine some conceptual tensions in Hick’s ‘pluralism’ in the light of S. Radhakrishnan’s reformulation of classical Advaita. Hick himself often quoted Radhakrishnan’s translations from the Hindu scriptures in support of his own claims about divine ineffability, transformative experience and religious pluralism. However, while Hick developed these themes partly through an adaptation of Kantian epistemology, Radhakrishnan derived them ultimately from Śaṁkara, and these two distinctive points of origin lead to somewhat different types of reconstruction of the diversity of world (...) religions. Our argument will highlight the point that Radhakrishnan is not a ‘pluralist’ in terms of Hick’s understanding of the Real. The Advaitin ultimate, while it too like Hick’s Real cannot be encapsulated by human categories, is, however, not strongly ineffable, because some substantive descriptions, according to the Advaitic tradition, are more accurate than others. Our comparative analysis will reveal that they differ because they are located in two somewhat divergent metaphysical schemes. In turn, we will be able to revisit, through this dialogue between Hick and Radhakrishnan, the intensely vexed question of whether Hick’s version of pluralism is in fact a form of covert exclusivism.

In Language and Equilibrium, Prashant Parikh offers a new account of meaning for natural language. He argues that equilibrium, or balance among multiple interacting forces, is a key attribute of language and meaning and shows how to derive the meaning of an utterance from first principles by modeling it as a system of interdependent games.His account results in a novel view of semantics and pragmatics and describes how both may be integrated with syntax. It considers many aspects of meaning--including (...) literal meaning and implicature--and advances a detailed theory of definite descriptions as an application of the framework.Language and Equilibrium is intended for a wide readership in the cognitive sciences, including philosophers, linguists, and artificial intelligence researchers as well as neuroscientists, psychologists, and economists interested in language and communication.

A vital point of dispute within both classical Indian thought and contemporary analytic ontology is the following: which facts are brute so that they are, so to speak, beyond any need of civilizing through logical transformations, conceptual revisions, or linguistic reformulations? In this article, we discuss certain strands of the debate in these fields with two central purposes in mind. Firstly, we shall argue that metaphysical debates are seemingly interminable partly because disputing parties carve up the ontological landscape in such (...) a manner that what one party views as primitive, basic, or fundamental is regarded by an opponent as derivative, imagined, or constructed and vice versa. Second, unlike debates over these themes in contemporary analytic ontology, the classical Indian counterparts were usually located within a soteriological context, where it was claimed that an individual should develop meditative praxis on the way towards the goal of ultimate liberation. While it might seem that one could appeal to “experience” in this manner to settle the debate over whether universals were fundamental ingredients of the fabric of reality or merely conceptual artefacts, we shall argue that this approach is complicated by the fact that aspirants in these traditions would interpret their experiences in accordance with their doctrinal schemes. Therefore, the question of whether or not this appeal succeeds leads us to an ongoing dispute in religious epistemology over whether experiences are completely “constructed” by doctrinal context.

This introductory text points to some of the diverse tapestries of Hindu worldviews where scriptural revelation, logical argumentation, embodied affectivity, moral reasoning, and aesthetic cultivation constitute densely interwoven conceptual threads.

The devotional literatures across the Hindu bhakti traditions of medieval India are shaped by distinctive styles of affective responses to the divine reality. A theme which recurs in several layers of their songs is a theological dialectic between divine majesty and divine accessibility; the divine is not only simply transcendent in the sense of being a distant deity but is also immanently present in and through a range of human sensitivities, emotions, and affectivities. We will highlight the dialectic in the (...) devotional songs of three medieval figures, Tulsīdās, Sūrdās, and Mādhavadeva, which are structured primarily by the devotional attitude of a servant towards the Lord. As we will see, this theological servitude is not to be understood as a form of abject servility, for the three poets, in their somewhat distinctive ways, can not only speak of the Lord as a friend and as a lover, but can even level various kinds of complaints, challenges, and accusations at the Lord. Thus, if the Lord’s transcendental sovereignty is emphasised by the devotee through the modes of self-censure, the Lord’s immanent availability is also highlighted through the protests that the devotee fervently makes to the seemingly uncaring Lord.

In a comparative study of karma theodicy and atonement theodicy, as developed by some Hindu and Christian theologians, this article argues that they present teleological visions where individuals become purged, purified, and perfected in and through their worldly suffering. A karma theodicy operates with the notion that there is some form of proportionality between past evil and present suffering, even if such correlations can only be traced by an enlightened sage or are known to the omniscient God. Christian mystics too (...) seek not so much to explain suffering as to identify suffering with the agony of Christ on the cross, and they envision such suffering as part of a unitive journey where their love of Christ is purified. In these ways, both styles of theodicy use rational resources towards the goal of explanation, while reminding their adherents that the faltering intelligibility that they seek is to be seen as an integral component of their active participation in a sense of theological mystery that enfolds, and yet transcends, their finite existences.

Most streams of Christianity have emphasized the unknowability of God, but they have also asserted that Christ is the criterion through whom we may have limited access to the depths of God, and through whose life and death we can formulate the doctrine of God as Triune. This standpoint, however, leads to certain complications regarding ‘translating’ the Christian message to adherents of other religious traditions, and in particular the question, ‘Why do you accept Christ as the criterion?’, is one that (...) Christian thinkers have attempted to answer in different ways. There are two influential responses to this query in recent Christian thought: an ‘evidentialist’ approach which gradually moves from a theistic metaphysics to a Christ-centred soteriology, and an ‘unapologetic’ standpoint which takes God's self-disclosure in Christ as the perspectival lens through which to view the world. The opposition between these two groups is primarily over the status of ‘natural theology’, that is, whether we may speak of a ‘natural’ reason, which human beings possess even outside the circle of the Christian revelation, and through which they may arrive at some minimalist understanding of the divine reality. I outline the status of ‘natural theology’ in these strands of contemporary Christian thought, from Barthian ‘Christomonism’ to post-liberal theology to Reformed epistemology, and suggest certain problems within these standpoints which indicate the need for an appropriately qualified ‘natural theology’. Most of the criticisms leveled against ‘natural theology’, whether from secular philosophers or from Christian theologians themselves, can be put in two groups: first, the arguments for God's existence are logically flawed, and, second, even if they succeed they do not point to the Triune God that Christians worship. In contrast to such an old-fashioned ‘natural theology’ which allegedly starts from premises self-evidently true for all rational agents and leads through an inexorable logic to God, the qualified version is an attempt to spell out the doctrinal beliefs of Christianity such as the existence of a personal God who interacts with human beings in different ways, and outline the reasons offered in defence of such statements. In other words, without denying that Christian doctrines operate at one level as the grammatical rules which structure the Christian discourse, such a natural theology insists on the importance of the question of whether these utterances are true, in the sense that they refer to an objective reality which is independent of the Christian life-world. Such a ‘natural theology’, as the discussion will emphasize, is not an optional extra but follows in fact from the internal logic of the Christian position on the universality of God's salvific reach.

We present a method for relevance sensitive non-monotonic inference from belief sequences which incorporates insights pertaining to prioritized inference and relevance sensitive, inconsistency tolerant belief revision. Our model uses a finite, logically open sequence of propositional formulas as a representation for beliefs and defines a notion of inference from maxiconsistent subsets of formulas guided by two orderings: a temporal sequencing and an ordering based on relevance relations between the putative conclusion and formulas in the sequence. The relevance relations are ternary (...) (using context as a parameter) as opposed to standard binary axiomatizations. The inference operation thus defined easily handles iterated revision by maintaining a revision history, blocks the derivation of inconsistent answers from a possibly inconsistent sequence and maintains the distinction between explicit and implicit beliefs. In doing so, it provides a finitely presented formalism and a plausible model of reasoning for automated agents. (shrink)

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)

We suggest that the issue of constructing andverifying social procedures, which we suggestively call socialsoftware, be pursued as systematically as computer software is pursued by computer scientists. Certain complications do arise withsocial software which do not arise with computer software, but thesimilarities are nonetheless strong, and tools already exist which wouldenable us to start work on this important project. We give a variety ofsuggestive examples and indicate some theoretical work which alreadyexists.

We offer a probabilistic model of rational consequence relations (Lehmann and Magidor, 1990) by appealing to the extension of the classical Ramsey-Adams test proposed by Vann McGee in (McGee, 1994). Previous and influential models of nonmonotonic consequence relations have been produced in terms of the dynamics of expectations (Gärdenfors and Makinson, 1994; Gärdenfors, 1993).'Expectation' is a term of art in these models, which should not be confused with the notion of expected utility. The expectations of an agent are some form (...) of belief weaker than absolute certainty. Our model offers a modified and extended version of an account of qualitative belief in terms of conditional probability, first presented in (van Fraassen, 1995). We use this model to relate probabilistic and qualitative models of non-monotonic relations in terms of expectations. In doing so we propose a probabilistic model of the notion of expectation. We provide characterization results both for logically finite languages and for logically infinite, but countable, languages. The latter case shows the relevance of the axiom of countable additivity for our probability functions. We show that a rational logic defined over a logically infinite language can only be fully characterized in terms of finitely additive conditional probability. (shrink)

Although policymakers and investigators still struggle to quantify and compare the effects of various Covid-related interventions, we are steadily amassing data that could help inform choices. The pandemic’s medical, social, and economic harms have been immense, and they warrant a continuous policy response. All decision makers use some type of mental model to weigh the pros and cons of various policy options. Rigorous economic evaluation formalizes this process. Value judgments will still be required, but economic evaluation can make the decision-making (...) process more systematic, comprehensive, and transparent. (shrink)

We develop an analysis of discourse anaphora—the relationship between a pronoun and an antecedent earlier in the discourse —using games of partial information. The analysis is extended to include information from a variety of different sources, including lexical semantics, contrastive stress, grammatical relations, and decision theoretic aspects of the context.

We propose a model for belief which is free of presuppositions. Current models for belief suffer from two difficulties. One is the well known problem of logical omniscience which tends to follow from most models. But a more important one is the fact that most models do not even attempt to answer the question what it means for someone to believe something, and just what it is that is believed. We provide a flexible model which allows us to give meaning (...) to beliefs in general contexts, including the context of animal belief , and of human belief which is expressed in language.

The standard theory for belief revision provides an elegant and powerful framework for reasoning about how a rational agent should change its beliefs when confronted with new information. However, the agents considered are extremely idealized. Some recent models attempt to tackle the problem of plausible belief revision by adding structure to the belief bases and using nonstandard inference operations. One of the key ideas is that not all of an agent's beliefs are relevant for an operation of belief change.In this (...) paper we incorporate the insights pertaining to local change and relevance sensitivity with the use of approximate inference relations. These approximate inference relations offer us partial solutions at any stage of the revision process. The quality of the approximations improves as we allow for more and more resources to be used. We are provided with upper and lower bounds to what would be obtained with the use of classical inference. (shrink)

The objective of this study was to take a closer look at defense-related expenses for medical malpractice cases over time. We conducted a retrospective review of medical malpractice claims reported to the Physician Insurers Association of America's Data Sharing Project with a closing date between January 1, 1985 and December 31, 2008. On average a medical malpractice claim costs more than $27,000 to defend. Claims that go to trial are much more costly to defend than are those that are dropped, (...) withdrawn, or dismissed. However, since the overwhelming majority of claims are dropped, withdrawn, or dismissed, the total amount spent to defend them surpasses that spent on claims that go to trial. Defense attorney expenses account for the majority of defense-related expenses (74%), while expert witness expenses and other expenses split the remaining 26%. A strong association was also found between the average indemnity payment and the amount it costs to defend individual claims by specialty. Our study found that defense-related expenses for medical malpractice claims are not an insignificant cost. As state and federal governments debate how to repair the malpractice system, addressing the high cost of defending claims should not be ignored. (shrink)

Whenever health care reform is debated, the state of the medical professional liability system in the United States re-emerges as an issue of importance. What exactly is broken with the MPL system and what the implications are is a point of contention among different stakeholder groups. Recent data demonstrate that medical liability premiums have been improving in recent years and the majority of premiums remained flat in 2010. General agreement still exists, however, that medical professional liability insurance premiums have become (...) unaffordable for many physicians, and coverage has become less available, especially for certain medical specialties and in specific areas of the country.Multiple factors go into the determination of medical professional liability insurance premiums including return on investments, reinsurance costs, claims frequency, average amount paid out on malpractice claims, defense expenses, and administrative costs such as underwriting expense.

IntroductionDeep brain stimulation has become a standard treatment option for select patients with Parkinson’s disease. The selection process and surgical procedures employed have, to date, not been standardized.MethodsA comprehensive 58-question web-based survey was developed with a focus on DBS referral practices and peri-operative management. The survey was distributed to the Parkinson’s Foundation Centers of Excellence, members of the International Parkinson’s Disease and Movement Disorders Society, and the Parkinson Study Group between December 2015 and May 2016.ResultsThere were 207 individual respondents drawn (...) from 59 countries and 6 continents, of whom 64% received formal training in DBS. Thirteen percent of centers reported that DBS could proceed despite a confidence level of < 50% for PD diagnosis. A case-based approach to DBS candidacy was applied in 51.3% of centers without a cut-off for levodopa-responsiveness. Surprisingly, 33% of centers regularly used imaging for diagnostic confirmation of idiopathic PD. Thirty-one percent of centers reported that neuropsychological evaluation did not affect DBS target selection. Approximately half of the respondents reported determination of DBS candidacy based on a multidisciplinary committee evaluation and 1/3rd reported that a committee was used for target selection. Eight percent of respondents felt that psychosocial factors should not impact DBS candidacy nor site selection. Involvement of allied health professionals in the preoperative process was sparse. There was high variability in preoperative education about DBS outcome expectations. Approximately half of the respondents did not utilize a “default brain target,” though STN was used more commonly than GPi. Specific DBS procedure techniques applied, as well as follow-up timelines, were highly variable.ConclusionResults revealed high variability on the best approaches for DBS candidate selection, brain target selection, procedure type, and postoperative practices. Cognitive and mood assessments were underutilized. There was low reliance on multidisciplinary teams or psychosocial factors to impact the decision-making process. There were small but significant differences in practice across global regions, especially regarding multidisciplinary teams. The wide variability of responses across multiple facets of DBS care highlights the need for prospective studies to inform evidence-based guidelines. (shrink)

One of the hardest parts of being a leader is handling disagreements about values. The skills required to do this are increasingly important in polarized societies where there is pressure for businesses and organizations to have a sense of purpose and "do the right thing."

Rather, we guide readers on a journey to rigorously explore their values and (...) better understand the values of others. We discuss the human psychology that drives conflicts over values as well as the philosophical frameworks that have guided people for millennia. We provide strategies, based in research from psychology and the behavioral sciences, whichthat readers can use to implement their values in their lives and their organizations. Topics covered include moral intuitions, self-serving biases, situational pressures, social norms, the role of business in society, consequentialism/utilitarianism, motives, perspective-taking, justice, fairness, and liberty.
