Conventional rockets are not a suitable technology for interstellar missions. Chemical rockets require a very large weight of propellant, travel very slowly compared to light speed, and require significant energy to maintain operation over periods of years. For example, the 722 kg Voyager spacecraft required 13,600 kg of propellant to launch and would take about 80,000 years to reach the nearest star, Proxima Centauri, about 4.3 light years away. There have been various attempts at developing ideas on which one might (...) base a spacecraft that would permit interstellar travel, such as spacewarps. In this paper we consider another suggestion from science fiction and explore how the quantum vacuum might be utilized in the creation of a novel spacecraft. The spacecraft is based on the dynamic Casimir effect, in which electromagnetic radiation is emitted when an uncharged mirror is properly accelerated in vacuum. The radiative reaction produces a dissipative force on the mirror that tends to resist the acceleration of the mirror. This force can be used to accelerate a spacecraft attached to the mirror. We also show that, in principle, one could obtain the power to operate the accelerated mirror in such a spacecraft using energy extracted from the quantum vacuum using the standard Casimir effect with a parallel plate geometry. Unfortunately the method as currently conceived generates a miniscule thrust, and is no more practical than a spacewarp, yet it does provide an interesting demonstration of our current understanding of the physics of the quantized electromagnetic field in vacuum.

In quantum field theory, coherent states can be created that have negative energy density, meaning it is below that of empty space, the free quantum vacuum. If no restrictions existed regarding the concentration and permanence of negative energy regions, it might, for example, be possible to produce exotic phenomena such as Lorentzian traversable wormholes, warp drives, time machines, violations of the second law of thermodynamics, and naked singularities. Quantum Inequalities have been proposed that restrict the size and duration of the (...) regions of negative quantum vacuum energy that can be accessed by observers. However, QIs generally are derived for situations in cosmology and are very difficult to test. Direct measurement of vacuum energy is difficult and to date no QI has been tested experimentally. We test a proposed QI for squeezed light by a meta-analysis of published data obtained from experiments with optical parametric amplifiers and balanced homodyne detection. Over the last three decades, researchers in quantum optics have been trying to maximize the squeezing of the quantum vacuum and have succeeded in reducing the variance in the quantum vacuum fluctuations to \ dB. To apply the QI, a time sampling function is required. In our meta-analysis different time sampling functions for the QI were examined, but in all physically reasonable cases the QI is violated by much or all of the measured data. This brings into question the basis for QI. Possible explanations are given for this surprising result. (shrink)

With the rising poverty in the Philippines, Filipino farm workers in Agusan del Sur faced distinctive challenges in their homes and working environment. This study aimed to discuss Filipino farm workers’ lived experiences, challenges, and coping mechanisms. Filipino farm workers shared their experiences that tapped into their psychological aspects. Mainly, the problem was stress, worry, and frustration centered on poverty and educational attainment. Some farm workers were likely unaware of the main problem that prolonged their hardships. Still, most have managed (...) to fortify their mental health. This report indicates that most Filipino farm workers in Agusan del Sur have a healthy psychological well-being. However, this statement does not change the intensity of their struggle to survive. (shrink)

An implicit association test (IAT) measures differential association of 2 target concepts with an attribute. The 2 concepts appear in a 2-choice task (e.g., flower vs. insect names), and the attribute in a 2nd task (e.g., pleasant vs. unpleasant words for an evaluation attribute). When instructions oblige highly associated categories (e.g., flower + pleasant) to share a response key, performance is faster than when less associated categories (e.g., insect + pleasant) share a key. This performance difference implicitly measures differential association (...) of the 2 concepts with the attribute. In 3 experiments, the IAT was sensitive to (a) near-universal evaluative differences (e.g., flower vs. insect), (b) expected individual differences in evaluative associations (Japanese + pleasant vs. Korean + pleasant for Japanese vs. Korean subjects), and (c) consciously disavowed evaluative differences (Black + pleasant vs. White + pleasant for self-described unprejudiced White subjects).

Dreams represent threat, but appear to do so metaphorically more often than realistically. The metaphoric representation of threat allows it to be conceptualized in a manner that is constant across situations (as what is common to all threats begins to be understood and portrayed). This also means that response to threat can come to be represented in some way that works across situations. Conscious access to dream imagery, and subsequent social communication of that imagery, can facilitate this generalized adaptive process, (...) by allowing the communicative dreamer access to the problem solving resources of the community.

No consensus yet exists on how to handle incidental fnd-ings in human subjects research. Yet empirical studies document IFs in a wide range of research studies, where IFs are fndings beyond the aims of the study that are of potential health or reproductive importance to the individual research participant. This paper reports recommendations of a two-year project group funded by NIH to study how to manage IFs in genetic and genomic research, as well as imaging research. We conclude that researchers (...) have an obligation to address the possibility of discovering IFs in their protocol and communications with the IRB, and in their consent forms and communications with research participants. Researchers should establish a pathway for handling IFs and communicate that to the IRB and research participants. We recommend a pathway and categorize IFs into those that must be disclosed to research participants, those that may be disclosed, and those that should not be disclosed. (shrink)

Scholars who have attempted to explain Iris Murdoch’s moral realism have done so in widely divergent ways, some characterizing her as a classical moral realist, others as a pragmatic moral realist, and still others as a “reflexive realist.”See, e.g., respectively, Fergus Kerr, “Back to Plato with Iris Murdoch,” in Immortal Longings: Versions of Transcending Humanity (London: Society for Promoting Christian Knowledge, 1997), 68–88; Sami Pihlstrom, Pragmatic Moral Realism: A Transcendental Defence (Amsterdam: Rodopi, 2005); and Maria Antonaccio, Picturing the Human: The (...) Moral Thought of Iris Murdoch (Oxford: Oxford University Press, 2000). For the purpose of this article, I follow Maria Antonaccio’s characterization of these realisms. See pages 3–4. None of these attempts, however, capture adequately Murdoch’s distinctive position. In an effort to improve upon these accounts, this article argues that a proper characterization of Murdoch’s view must regard her as developing a version of m. (shrink)

In this dissertation I argue that Murdoch’s philosophical-ethical project is best understood as an anti-Enlightenment genealogical narrative. I maintain that her work consistently displays four fundamental features that typify genealogical accounts: 1) liberation from a dominant philosophical picture; 2) restoration of a previous philosophical picture wrongly dismissed; 3) restoration of practices no longer intelligible on the dominant view; and 4) recovery of an alternative grammar at odds with the dominant philosophical discourse. The dominant philosophical picture Murdoch subverts is the eclipse (...) of consciousness wrought by both the Anglo-analytic and Continental-existentialist traditions. Whether effaced by totalizing linguistic structures or identified with an empty choosing will, Murdoch argues that the forces present within her philosophical context are fundamentally hostile to an adequate conception of consciousness. Her genealogical project attempts to reassert the primacy of consciousness within this antagonistic climate by restoring a Platonic, erotic conception of consciousness. Additionally, Murdoch insists that consciousness is the fundamental form of moral being and that moral transformation, including the practices for that transformation, cannot be understood without a thick conception of consciousness. Murdoch’s account, therefore, refocuses our attention on important practices or techniques of moral purification rendered unintelligible on the dominant view. Finally, Murdoch recovers the Platonic metaphor of the Good, including the conceptual array in which the Good receives its meaning, in an attempt to develop an alternative grammar fit for the task of picturing the complexities and nuances of our ethical situation. I conclude by commenting on both the promising and problematic aspects of Murdoch’s legacy. (shrink)

Although thick ethical concepts have been neglected in Murdochian scholarship, this article argues that they were central to the thought of Iris Murdoch. In the first section, the article provides a sustained account of thick ethical concepts in Murdoch's philosophy, demonstrating how these concepts align with and illuminate familiar aspects of her philosophical essays. The first section also explores the ways in which Murdoch's alternative account of moral concepts was at the heart of her overall attack on the noncognitivism of (...) her day. In the second section, the article provides a reading of The Black Prince and considers the ways that thick ethical concepts offer new insight into Murdoch's literary activity. It concludes by suggesting that studying Murdoch's philosophy and literature in light of thick ethical concepts reveals a deep unity between her two intellectual projects. (shrink)

In this paper I argue that narratives concerning Periclean Athens have mistakenly imposed modern conceptions of enlightenment onto the Greek world,and have therefore been blinded to crucial aspects of Socrates’s practice of moral reason giving. In contrast to the Kantian conception of enlightenment, which puts forth an image of the ideally enlightened person as an autonomous reasoner, one who refuses to be guided by another and who has the courage to throw off the chains of tradition and “think for oneself,” (...) I argue that Socrates provides us with a much different picture of the enlightened individual. Socrates’s practice of moral reasoning does not take the form of autonomous rationality that is antithetical to tradition, but rather his practice recognizes the rightful authority of tradition and custom in moral reason giving. Thus, rather than characterizing Socrates through a Kantian enlightenment reading, this paper argues that we should study Socrates through the lens of the sensus communis, a humanist concept articulated well by Giambattista Vico and Hans Georg-Gadamer.

While the global threat of Ebola Virus Disease in 2014 was concentrated in several West African countries, its effects have been felt in many developed countries including the United States. Initial, select patients with EVD, largely among American health care workers volunteering in affected regions, were subsequently transported back to the states for isolation and treatment in high-level medical facilities. This included Emory University Hospital, which sits adjacent to the federal Centers for Disease Control and Prevention in Atlanta, Georgia.The first (...) domestic case of EVD occurred in late September in Dallas, Texas. Additional exposures of two HCWs generated an array of legal issues for state and local public health authorities, hospitals, and providers. Consideration of these issues led to extensive discussion among lawyers, public health practitioners, and other attendees at a late-breaking session on EVD and Legal Preparedness at the 2014 National Public Health Law conference. In this commentary, session presenters from CDC and Emory University share their expert perspectives on legal and policy issues underlying state and local powers to quarantine and isolate persons exposed to or infected with Ebola, as well as facets of hospital preparedness underlying the successful treatment of patients with EVD.

Chemical kinds (e.g. gold) are generally treated as having timelessly fixed identities. Biological kinds (e.g. goldfinches) are generally treated as evolved and/or evolving entities. So what kind of kind is a biochemical kind? This paper defends the thesis that biochemical molecules are clustered chemical kinds, some of which–namely, evolutionarily conserved units–are also biological kinds.On this thesis, a number of difficulties that have recently occupied philosophers concerned with proteins and kinds are shown to be resolved or dissolved.

Rules are meant to apply equally to all within their jurisdiction. However, some rules are frequently broken without consequence for most. These rules are only occasionally enforced, often at the discretion of a third-party observer. We propose that these rules—whose violations are frequent, and enforcement is rare—constitute a unique subclass of explicitly codified rules, which we call ‘phantom rules’ (e.g., proscribing jaywalking). Their apparent punishability is ambiguous and particularly susceptible to third-party motives. Across six experiments, (N = 1440) we validated (...) the existence of phantom rules and found evidence for their motivated enforcement. First, people played a modified Dictator Game with a novel frequently broken and rarely enforced rule (i.e., a phantom rule). People enforced this rule more often when the “dictator” was selfish (vs. fair) even though the rule only proscribed fractional offers (not selfishness). Then we turned to third person judgments of the U.S. legal system. We found these violations are recognizable to participants as both illegal and commonplace (Experiment 2), differentiable from violations of prototypical laws (Experiments 3) and enforced in a motivated way (Experiments 4a and 4b). Phantom rule violations (but not prototypical legal violations) are seen as more justifiably punished when the rule violator has also violated a social norm (vs. rule violation alone)—unless the motivation to punish has been satiated (Experiment 5). Phantom rules are frequently broken, codified rules. Consequently, their apparent punishability is ambiguous, and their enforcement is particularly susceptible to third party motives. (shrink)

It is often assumed that engaging in a one‐on‐one dialogue with a tutor is more effective than listening to a lecture or reading a text. Although earlier experiments have not always supported this hypothesis, this may be due in part to allowing the tutors to cover different content than the noninteractive instruction. In 7 experiments, we tested the interaction hypothesis under the constraint that (a) all students covered the same content during instruction, (b) the task domain was qualitative physics, (c) (...) the instruction was in natural language as opposed to mathematical or other formal languages, and (d) the instruction conformed with a widely observed pattern in human tutoring: Graesser, Person, and Magliano's 5‐step frame. In the experiments, we compared 2 kinds of human tutoring (spoken and computer mediated) with 2 kinds of natural‐language‐based computer tutoring (Why2‐Atlas and Why2‐AutoTutor) and 3 control conditions that involved studying texts. The results depended on whether the students' preparation matched the content of the instruction. When novices (students who had not taken college physics) studied content that was written for intermediates (students who had taken college physics), then tutorial dialogue was reliably more beneficial than less interactive instruction, with large effect sizes. When novices studied material written for novices or intermediates studied material written for intermediates, then tutorial dialogue was not reliably more effective than the text‐based control conditions.

The purpose of this study is to describe the development of philosophy in Poland since the end of the Second World War and the development of Marxist-Leninist philosophy which, owing to international political events, has assumed an impor tant role in the intellectual life of contemporary Poland. This task could not have been accomplished without relating post-war developments to those of the inter war period. Consequently, the period studied covers the years 1918-1958. Yet another extension was necessary. Marxism-Leninism regards sociology (...) as a part of philosophy. Moreover, Marxism-Leninism often resorts to sociology to support or justify some of its philosophical views. Finally, its criticism of 'bourgeois philosophy' is often concerned with social philosophy and socio logical theories which supposedly are implicit or explicit in 'bourgeois philoso phy'. For this reason it was desirable to consider in this study some theoretical and methodological problems of the social sciences. They are taken into ac count when they illuminate philosophical controversies or the evolution of Marxist-Leninist philosophy. Marxism-Leninism is not only a new line of development but also a new point of departure in Polish philosophy. It provides a striking contrast with the established philosophical tradition which originated roughly at the time when G. E. Moore and Bertrand Russell initiated the analytical trend in English philosophy. The contrast can be epitomised by the contradistinction of philoso phy and ideology, chosen as the title of this study. (shrink)

What does it mean to consider the world of AI through a Christian lens? Rapid developments in AI continue to reshape society, raising new ethical questions and challenging our understanding of the human person. Encountering Artificial Intelligence draws on Pope Francis’ discussion of a culture of encounter and broader themes in Catholic social thought in order to examine how current AI applications affect human relationships in various social spheres and offers concrete recommendations for better implementation. The document also explores questions (...) regarding personhood, consciousness, and the kinds of relationships humans might have with even the most advanced AI. Through these discussions, this book investigates the theoretical and practical challenges to interpersonal encounter raised by the age of AI.

Background Fecal microbiota transplant (FMT) is a treatment modality that involves the introduction of stool from a healthy pre-screened donor into the gastrointestinal tract of a patient. It exerts its therapeutic effects by remodeling the gut microbiota and treating microbial dysbiosis-imbalance. FMT is not regulated in Jordan, and regulatory effort for FMT therapy in Jordan, an Islamic conservative country, might be faced with unique cultural, social, religious, and ethical challenges. We aimed to assess knowledge, attitudes, and perceptions of (...) ethical and social issues of FMT use among Jordanian healthcare professionals. Methods An observational, cross-sectional study design was used to assess knowledge, attitudes, and perceptions of ethical and social issues of FMT among 300 Jordanian healthcare professionals. Results A large proportion (39 %) thought that the safety and efficacy of this technique are limited and 29.3 % thought there is no evidence to support its use. Almost all (95 %) responded that they would only perform it in certain cases, if ethically justified, and 48.3 % would use it due to treatment failure of other approaches. When reporting about reasons for not using it, 40 % reported that they would not perform it due to concerns about medical litigation, fear of infections (38 %), and lack of knowledge of long safety and efficacy (31.3 %). Interestingly, all practitioners said they would perform this procedure through the lower rather than upper gastrointestinal tract modality and the majority will protect the patient’s confidentiality via double-blinding (43.3 %). For a subset of participants (n = 100), the cultural constraints that might affect the choice of performing FMT were mainly due to donor’s religion, followed by dietary intake, and alcohol consumption. Conclusions Our healthcare practitioners are generally reluctant to use the FMT modality due to religious and ethical reasons but would consider it if there was a failure of other treatment and after taking into consideration many legislative, social, ethical and practice-based challenges including safety, efficacy and absence of guidelines.

Some Christian theologians and philosophers maintain that God’s punishments are always (at least partly) motivated by redemptive love for those punished, even when these punishments are considerably severe (e.g., killings or damnations). However, advocates of such a conception of divine punishment face significant challenges. Perhaps most fundamentally, it is not entirely apparent how severe and loving features of divine punishment might be understood to fit together within a viable theological model. In this article this foundational issue is addressed. By culling (...) resources from St. Gregory of Nyssa, the present aim is to proffer a contemporary model of divine punishment that naturally combines redemptive love for those punished with apparently harsh treatment.

Following the levels of intentionality and semiosis distinguished by the Semiotic Hierarchy, and the distinction between original agency and enhanced agency, we propose a model of an agency hierarchy, consisting of six layers. Consistent with the phenomenological orientation of cognitive semiotics, a central claim is that agency and subjectivity are complementary aspects of intentionality. Hence, there is no agency without at least the minimal sense/feeling of agency. This perspective rules out all artefacts as genuine agents, as well as simple organisms, (...) since it is highly unlikely that e.g. bacteria have any first-person perspective. Using this model, we review and assess recent proposals on the nature of agency from cognitive science, and neuroscience, and draw conclusions on how to incorporate aspects of them within a synthetic cognitive-semiotic framework.

It is being increasingly recognized that the Saussurean dictum of “the arbitrariness of the linguistic sign” is in conflict with the pervasiveness of the phenomenon commonly known as “sound symbolism”. After first presenting a historical overview of the debate, however, we conclude that both positions have been exaggerated, and that an adequate explanation of sound symbolism is still lacking. How can there, for example, be (perceived) similarity between expressionsand contents across different sensory modalities? We offer an answer, based on the (...) Peircian notion of iconic ground, and G. Sonesson’s distinction betweenprimary and secondary iconicity. Furthermore, we describe an experimental study, in a paradigm first pioneered by W. Kohler, and recently popularized by V.Ramachandran, in which we varied vowels and consonants in fictive word-forms, and conclude that both types of sounds play a role in perceiving an iconic ground between the word-forms and visual figures. The combination of historical conceptual analysis, semiotic explication and psychological experimentationpresented in this article is characteristic of the emerging paradigm of cognitive semiotics.

Peter van Inwagen’s short piece on the possibility of resurrection via simulacrum from 1978 has been regularly condemned for its overall implausibility. However, this paper argues that van Inwagen’s thesis has been unfairly criticized and remains a live and salutary option. It begins by summarizing the metaphysics of the simulacrum theory of the resurrection alongside the motivation for such a theory. Next, it challenges the four main criticisms against the van Inwagen styled simulacrum model. First, it argues that while van (...) Inwagen’s model may appear unnecessary or irrelevant for those that reject his metaphysics of human persons, an account like his is necessary for those that desire to maintain the traditional metaphysics of resurrection (e.g., the resurrection of the “self-same” body). Second, it argues that his model does not implicate God in mass deception or irreverence for the dead. Third, it rejects the idea that van Inwagen’s model is analogous to the implausibility of young earth creationism and its required claims like dinosaur bones being given the appearance of age. Fourth, it argues that his model is not metaphysically impossible for scenarios where someone is simultaneously killed and destroyed, such as in nuclear blasts. (shrink)

In this paper, we present and defend a modest anti-realist conception of aesthetic properties – e.g. being unified, moving, delicate, tragic, etc – in order to motivate a contextualist semantic view about aesthetic judgments. We argue that aesthetic properties are plausibly seen as viewpoint-dependent even though our epistemic access to the presence of aesthetic properties is decidedly more complicated than other, less controversial instances of viewpoint-dependent properties. On the basis of our anti-realist conception, we argue, utilizing the Kaplanian distinction between (...) character and content within a possible worlds semantic theory, that the contents expressed in aesthetic thought and language are sensitive to certain contextual features of a particular thinker’s or speaker’s situation. Finally, we address a number of formidable objections to our view, objections concerning certain context-sensitivity diagnostics, and sho... (shrink)

A wide array of syntactic phenomena can be categorized as being either direction-sensitive (e.g. coordination) or direction-insensitive (quantification and medial extraction). In the realm of categorial grammar, many frameworks are engineered to handle one class of phenomena at the expense of the other. In particular, Lambek-inspired frameworks handle direction-sensitivity elegantly but struggle with cases of direction-insensitivity, whereas in linear grammars, the situation is just the opposite. One reasonably successful attempt to unify the insights of both types of grammar and allow (...) for the analysis of direction-sensitive as well as direction-insensitive phenomena is hybrid type-logical categorial grammar (HTLCG), which augments the set of syntactic categories of an ordinary linear grammar with the directional slashes of a Lambek grammar. In this paper, the complementary nature of Lambek and linear grammars, with respect to direction-sensitive and direction-insensitive phenomena, is expounded on, as is the nature of how HTLCG attempts to reconcile the two systems. The paper further discusses an alternative to HTLCG—a linear grammar which adds Lambek-like capabilities by augmenting the string-combining (phenogrammatic) mechanism instead of the definition of syntactic categories (the tectogrammar). In particular, LCGϕ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\hbox {LCG}_\phi $$\end{document} (linear categorial grammar with phenominators) adds a form of subtyping based on phenominators—a class of linear functions which specify various modes of (phenogrammatic) combination.

In a series of important papers, Justin D’Arms and Daniel Jacobson argue that all extant neo-sentimentalists are guilty of a conflation error that they call the moralistic fallacy. One commits the moralistic fallacy when one infers from the fact that it would be morally wrong to experience an affective attitude—e.g., it would be wrong to be amused—that the attitude does not fit its object—e.g., that it is not funny. Such inferences, they argue, conflate the appropriateness conditions of attitudinal responses with (...) the fittingness conditions of the associated evaluative properties. Further, they argue that moral considerations are irrelevant for determining if amusement fits its object. We agree that a strong moralizing of humor is wrongheaded and that jokes can be quite funny even in cases where we have a compelling moral reason to not be amused. However, we argue that pace D’Arms and Jacobson moral considerations can be relevant for property ascription. On our view, in order for a joke to be funny, a properly sensitive agent must take herself to have a contributory reason to be amused, and in some cases that she lacks such a reason is best explained by appeal to moral considerations. We use this constraint as the basis of what we call our modest proposal for a modest sentimentalism. (shrink)

Some particularists have argued that even virtue properties can exhibit a form of holism or context variance, e.g. sometimes an act is worse for being kind, say. But, on a common conception of virtuous acts, one derived from Aristotle, claims of virtue holism will be shown to be false. I argue, perhaps surprisingly, that on this conception the virtuousness of an act is not a reason to do it, and hence this conception of virtuous acts presents no challenge to particularist (...) claims about the context variance of reasons. Still, I argue that the virtues nevertheless have important implications for our understanding of the particularism debate. Specifically, we can accept the particularist claim that reasons do not need to be principled in order to have the normative status that they do have, while still maintaining that sound moral thought and judgement has a principled structure understood in terms of the virtues.

Das vorliegende Buch versucht in einer systematischen Ge­ samtübersicht den Gedankeninhalt der modernen Physik zu er­ läutern. Mit Einzelheiten der experimentellen Technik sollte der Leser dabei ebensowenig belastet werden, wie mit den mathe­ matischen Formulierungen der Theorie; ohne uns zu sehr in der Fülle betrachtenswerter Einzelheiten zu verlieren, wollen wir unsere Aufmerksamkeit auf die entscheidenden Tatsachen und Einsichten, auf die leitenden Gesichtspunkte der Forschung richten - und auf die geistige Einstellung, welche der modernen Physik ihr charakteristisches philosophisches Gepräge gibt, und (...) welche die Erringung ihrer umstürzenden Erkenntnisse ermög­ licht hat. Wir beginnen mit einer nachdenklichen Betrachtung der klassischen G a I i I e i - N e w t o n sehen Mechanik, deren Sinn und Bedeutung eindringlich verstanden zu haben Vorbedin­ gung ist für jedes Verständnis der revolutionären Entwicklungen der modernen Physik.

"The Wisdom of Being Religious" is important because (i) it is explicitly mentioned by Hume in his A Letter From A Gentleman to His Friend in Edinburgh (1745; reprint, Edinburgh, 1967), 23, so we know that Hume had read this sermon; (ii) it was one of the best known of Tillotson's sermons; and (iii) it contains all of the elements of Tillotson's argument from prudence.7. T. Birch, "Life of the Author," in Works of Tillotson, 1:xix-xx. See also L. G. Locke, Tillotson (Copenhagen, 1954).8. Tillotson may have been aware of the Port Royal Logic version of the wager through Locke with whom Tillotson was in correspondence. See Tillotson, 83.9. Tillotson's case for (1) is treated extensively in his sermon, "The Advantage of Religion to Societies," Sermon 3 in Works of Tillotson, 1:409-23.10. In the passage quoted (W 361-62), Tillotson claims that the atheist will naturally dread a superior being who can defeat one's plans and judge one's actions.11. See also "The Efficacy, Usefulness, and Reasonableness Of Divine Faith," Sermon 223 in Works of Tillotson, 9:258-79. The idea of a grand lie is first found in Plato; see Republic 3:389, 414, 5:459.12. "Pascalian Wagering," Canadian Journal of Philosophy 16, no. 3 (1986): 437-54.13. Though Tillotson mentions "odds" and "hazards," he does not incorporate probability values in his version of the wager. His wager is a decision under uncertainty and not a decision under risk: he does not, that is, calculate the expected utility of theistic belief. Pascal was the first to formulate the wager as a decision under risk where the probability-weighted averages of the utility values (the expected utility) determine the right choice.14. Of course, these principles were not stated explicitly until much later. See Ian Hacking, The Emergence of Probability (London, 1975).15. For an example of the many-gods objection, see M. Martin, Atheism: A Philosophical Justification (Philadelphia, 1990), 232-34. For a response to the many-gods objection see my "Pascal's Wager and the Many-Gods Objection," International Philosophical Quarterly 31, no. 3 (1991): 309-17.16. See David Hume, Dialogues Concerning Natural Religion, ed. N. Kemp Smith (1778; reprint, Indianapolis, 1947), 214, 218 (hereafter cited as "D").17. It should be noted that Philo's first point is interrupted by the second and is not completed until after the second is completed.18. I will assume that Philo speaks for Hume in this exchange with Cleanthes (D 219-27). Of the three points asserted by Philo in this exchange all three are asserted elsewhere by Hume. On the first point, see The Natural History of Religion (1757), secs. 9 and... (shrink)

Having defined a notion of homology for paired graphs, Métayer ([Ma]) proves a homological correctness criterion for proof nets, and states that for any proof net \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $G$\end{document} there exists a Jordan-Hölder decomposition of \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} ${\mathsf H}_0(G)$\end{document}.
