According to a prominent view in Jewish-Halakhic literature, “mitzvot (commandments) require intention.” That is, to fulfill one’s obligation in performing a commandment, one must intend to perform the act because it’s a mitzvah; one must take the fact that one’s act is a mitzvah as her reason for doing the action. I argue that thus understood, this Halakhic view faces a revised version of Thomas Hurka’s recent dilemma for structurally similar views in ethics: either it makes it a necessary condition (...) for the act’s being a mitzvah that one has a false belief about the act’s Halakhic status, or it commits proponents of the “mitzvot require intention” view to a sort of rational failure in performing the mitzvot. The dilemma arises, however, only if we interpret this Halakhic view as requiring one to have a belief about her act’s Halakhic status in order for it to have this status. I suggest that the dilemma can be avoided by interpreting the intention requirement as requiring a make-belief, instead of a belief. Under this understanding, Halakha (or God) doesn’t care about why one performs an act of a mitzvah, but rather about how she does it; how she sees and experiences her action. This suggests another form of worship central to Judaism—worship via make-believing. (shrink)

O presente estudo teve como objeto a Sociedade de São Vicente de Paulo - SSVP, e visou analisar a crise institucional da associação, relacionando-a com a crise religiosa contemporânea, tendo em vista a dificuldade na admissão de novos quadros para a entidade, como também a complexidade da manutenção de seus membros. A motivação do trabalho foi compreender como a crise socioreligiosa contemporânea contribui para esse processo, valendo-se também da observação empírica nas reuniões, festas e eventos realizados pela instituição. Buscou-se ainda (...) identificar alguns fatores externos e internos à instituição, e suas implicações, que estão contribuindo para esse desequilíbrio. Para isso, foi utilizado como método principal de coleta de dados a pesquisa bibliográfica, em fontes e documentos da SSVP, como a Regra e o Regulamento; boletins, revistas e atas da entidade, como também obras de autores que estudam a SSVP. Houve também, metodologicamente, a observação através da presença numa Conferência Vicentina, pertencente ao Conselho Central Sagrados Corações. Bibliograficamente, ainda foram analisadas algumas obras de pesquisadores que refletem sobre a realidade religiosa contemporânea, abordando temas como secularização, modernidade, pluralismo religioso, crise de sentido, transmissão religiosa, crise religiosa contemporânea, mobilidade social e religiosa e juventude, a fim de entender de que maneira tais temas podem ajudar na análise do catolicismo e, consequentemente, da crise institucional da SSVP. A dissertação procurou refletir sobre perspectivas e as novas demandas sociais que podem desafiar a entidade a dialogar com a sociedade contemporânea, especialmente com os jovens, oferecendo um horizonte de renovação e de futuro para o carisma da entidade. Para uma entidade centenária, se tornou difícil para os próprios vicentinos incluir seus familiares, sobretudo os próprios filhos, para o trabalho dentro da associação. A análise realizada confirmou a hipótese que realmente a entidade atravessa uma crise sem precedentes e que serão necessárias inovações, aberturas, estratégias e novas pedagogias, se houver interesse em mudar, enfrentar os desafios atuais e renovar a SSVP e seu carisma. Para isso, ela precisará contar com a força e o dinamismo da juventude e de seus membros e dirigentes. A pesquisa realizada no Programa de Pós-graduação em Ciências da Religião da PUC Minas foi desenvolvida na Área de Concentração “Religião e Cultura” e na Linha de Pesquisa “Religião, Política e Educação”.

This book traces the deployment of intermedial aesthetics in the works of early twentieth-century female performers. By destabilizing medial and genre boundaries, these women created compelling and meaningful performances that negotiated turn-of-the-century American social and cultural issues.

Este estudo trata da crítica que Sloterdijk faz ao humanismo e a Heidegger em seu livro Regra para o parque humano uma resposta à carta de Heidegger sobre o humanismo. Essa crítica se desenvolve contra a concepção do humano como animal rationale de origem humanista, e contra a uma onto-antropologia imputada à Heidegger por Sloterdijk. O desenvolvimento mostra que elementos de domesticação e seleção persistem desde a Antinguidade e hoje se apresentam sob novas formas. A proposta de Sloterdijk é a (...) elaboração de uma antropotécnica para lidar com o humano. Nesse contexto, esse artigo busca responder a seguinte questão: qual o estatuto da biopolítica em um cenário da antropotécnica plenamente desenvolvida? Os resultados mostram que, em tal cenário, ainda existiria biopolítica, mas a determinação das diretrizes poderia não mais ser feita por humanos, mas apenas por um aparato técnico. (shrink)

Suppose someone is brought up as an orthodox Jew, and so only eats kosher, is very conservative sexually, etc. Suppose they then find out that this Judaism stuff is just all a big mistake. If they then regret all the shrimp they could have eaten, all the sex!, this makes perfect sense. Not so, however, if someone finds out that moral realism is false, and they now regret all the fun they could have had hurting people’s feeling, etc. Even if (...) this does make sense, there’s a strong disanalogy between the moral and the religious case. This asymmetry, on a realist picture of morality, calls for explanation. This chapter tries to explain it. The discussion engages some topics familiar from objections to Robust realism—the why-be-moral challenge, the status of de-dicto moral motivation, and whether and why we should care about the moral properties, robustly realistically understood.

We develop a systematic approach to quantum probability as a theory of rational betting in quantum gambles. In these games of chance the agent is betting in advance on the outcomes of several incompatible measurements. One of the measurements is subsequently chosen and performed and the money placed on the other measurements is returned to the agent. We show how the rules of rational betting imply all the interesting features of quantum probability, even in such finite gambles. These include the (...) uncertainty principle and the violation of Bell's inequality among others. Quantum gambles are closely related to quantum logic and provide a new semantics to it. We conclude with a philosophical discussion on the interpretation of quantum mechanics. (shrink)

This paper offers a new semantic theory of existentials (sentences of the form There be NP pivot XP coda ) in which pivots are (second order) predicates and codas are modifiers. The theory retains the analysis of pivots as denoting generalized quantifiers (Barwise and Cooper 1981; Keenan 1987), but departs from previous analyses in analyzing codas as contextual modifiers on a par with temporal/locative frame adverbials. Existing analyses universally assume that pivots are arguments of some predicate, and that codas are (...) main or secondary predicates. It is shown that these analyses cannot account for the behavior of codas with quantifiers and for the interaction of multiple codas, both of which receive a simple treatment on the proposed theory. The assimilation of codas to frame adverbials explains several semantic properties which have not been analyzed in the semantic literature, and that distinguish existentials from their copular counterparts. Furthermore, it highlights important properties of the semantics of modification and its relation to predication. (shrink)

Statistical learning is often taken to lie at the heart of many cognitive tasks, including the acquisition of language. One particular task in which probabilistic models have achieved considerable success is the segmentation of speech into words. However, these models have mostly been tested against English data, and as a result little is known about how a statistical learning mechanism copes with input regularities that arise from the structural properties of different languages. This study focuses on statistical word segmentation in (...) Arabic, a Semitic language in which words are built around consonantal roots. We hypothesize that segmentation in such languages is facilitated by tracking consonant distributions independently from intervening vowels. Previous studies have shown that human learners can track consonant probabilities across intervening vowels in artificial languages, but it is unknown to what extent this ability would be beneficial in the segmentation of natural language. We assessed the performance of a Bayesian segmentation model on English and Arabic, comparing consonant-only representations with full representations. In addition, we examined to what extent structurally different proto-lexicons reflect adult language. The results suggest that for a child learning a Semitic language, separating consonants from vowels is beneficial for segmentation. These findings indicate that probabilistic models require appropriate linguistic representations in order to effectively meet the challenges of language acquisition. (shrink)

The existence of fields besides gravitation may provide us with a way to decide empirically whether spacetime is really a nonflat Riemannian manifold or a flat Minkowskian manifold that appears curved as a result of gravitational distortions. This idea is explained using a modification of Poincaré's famous 'diskworld'.

Some philosophers think that knowledge or justification is both necessary and sufficient for rational action: they endorse knowledge-action or justification-action biconditionals. This paper offers a novel, metaphysical challenge to these biconditionals, which proceeds with a familiar question: What depends on what? If you know that p iff it is rational for you to act on p, do you know that p partly because it is rational for you to act on p, or is it rational for you to act on (...) p partly because you know that p? And a structurally similar question can be asked regarding justification-action biconditionals. I argue that proponents of these biconditionals cannot give a satisfactory answer to these questions. This is because each direction of these biconditionals strongly supports an opposite order of explanation to the one that is supported by the other direction. Given the traditional assumption that metaphysical explanations—even partial ones—are asymmetric, I argue that these biconditionals should be rejected. While knowledge might be necessary for rational action, and it might be sufficient, it cannot be both. And the same goes for justification. (shrink)

Localist models of spreading activation (SA) and models assuming distributed representations offer very different takes on semantic priming, a widely investigated paradigm in word recognition and semantic memory research. In this study, we implemented SA in an attractor neural network model with distributed representations and created a unified framework for the two approaches. Our models assume a synaptic depression mechanism leading to autonomous transitions between encoded memory patterns (latching dynamics), which account for the major characteristics of automatic semantic priming in (...) humans. Using computer simulations, we demonstrated how findings that challenged attractor‐based networks in the past, such as mediated and asymmetric priming, are a natural consequence of our present model’s dynamics. Puzzling results regarding backward priming were also given a straightforward explanation. In addition, the current model addresses some of the differences between semantic and associative relatedness and explains how these differences interact with stimulus onset asynchrony in priming experiments.

This book compares various approaches to the interpretation of quantum mechanics, in particular those which are related to the key words "the Copenhagen interpretation", "the antirealist view", "quantum logic" and "hidden variable theory". Using the concept of "correlation" carefully analyzed in the context of classical probability and in quantum theory, the author provides a framework to compare these approaches. He also develops an extension of probability theory to construct a local hidden variable theory. The book should be of interest for (...) physicists and philosophers of science interested in the foundations of quantum theory. (shrink)

Moral realism is often taken to have common sense and initial appearances on its side. Indeed, by some lights, common sense and initial appearances underlie all the central positive arguments for moral realism. We offer a kind of debunking argument, taking aim at realism’s common sense standing. Our argument differs from familiar debunking moves both in its empirical assumptions and in how it targets the realist position. We argue that if natural selection explains the objective phenomenology of moral deliberation and (...) judgement, then this undermines arguments from that phenomenology. This results in a simpler, and in some ways more direct, challenge to realism. It is also less vulnerable to the main objections that have been leveled against such arguments. If accepted, our conclusion should make a real difference to the dialectic in this area. It means that neither realism nor its denial is the default, to-be-refuted, position. (shrink)

Semantic priming has long been recognized to reflect, along with automatic semantic mechanisms, the contribution of controlled strategies. However, previous theories of controlled priming were mostly qualitative, lacking common grounds with modern mathematical models of automatic priming based on neural networks. Recently, we introduced a novel attractor network model of automatic semantic priming with latching dynamics. Here, we extend this work to show how the same model can also account for important findings regarding controlled processes. Assuming the rate of semantic (...) transitions in the network can be adapted using simple reinforcement learning, we show how basic findings attributed to controlled processes in priming can be achieved, including their dependency on stimulus onset asynchrony and relatedness proportion and their unique effect on associative, category-exemplar, mediated and backward prime-target relations. We discuss how our mechanism relates to the classic expectancy theory and how it can be further extended in future developments of the model. (shrink)

This paper discusses the semantics of bare existentials , i.e. existentials in which nothing follows the post copular NP (e.g. There are four sections ). While it has sometimes been recognized that the interpretation of such sentences depends in some way on context, the exact nature of the context dependence involved has not been properly understood. It is shown that the meaning of bare existentials involves a set-denoting implicit argument, and that the range of interpretations found with bare existentials is (...) predictable from the general properties of implicit arguments. An explicit analysis within a dynamic setting is presented. (shrink)

This book explores a key issue in linguistic theory, the systematic variation in form between semantic equivalents across languages. Two contrasting views of the role of lexical meaning in the analysis of such variation can be found in the literature: (i) uniformity, whereby lexical meaning is universal, and variation arises from idiosyncratic differences in the inventory and phonological shape of language-particular functional material, and (ii) transparency, whereby systematic variation in form arises from systematic variation in the meaning of basic lexical (...) items.

In this paper, the authors describe an aspect of a program of research around grief and clinical practice. The first phase of the study involves examination of experiences of grief with attention to troublesome or problematic beliefs that fuel the extent of suffering in the bereaved. The data, obtained from a review of videotaped clinical interviews with families seen in the Family Nursing Unit at the University of Calgary, were analyzed according to philosophical hermeneutic tradition. Findings suggest that grief is (...) an experience that is ongoing, that changes in nature over time, but that involves a continuing relationship with the deceased; it is a graceful, periodic, deliberate walk backwards while keeping a sure foot in living forward.

This paper explores an understudied and poorly understood phenomenon of morphological syncretism in which a morpheme otherwise used to mark the head of a possessive NP appears on words naming property concept (PC) states (states named by adjectives in languages with that lexical category; Dixon, Where have all the adjectives gone? And other essays in Semantics and Syntax, 1982) in predicative and attributive contexts. This phenomenon is found across a variety of unrelated languages. We examine its manifestation in Ulwa, an (...) endangered Misumalpan language of Nicaragua, where diachronic evidence clearly shows that a single affix is involved. We propose an explanation for the syncretism based on an explicit syntactic and semantic analysis of the relevant constructions. On the proposed explanation, the syncretism arises out of a combination of semantic and morphosyntactic facts of Ulwa grammar. Specifically, we propose that the Ulwa pattern exemplifies a possessive strategy of predication. Intuitively, this strategy is a manifestation in grammar of the idiomatic equivalence between the property of being F and the property of having F-ness. (shrink)

The paper proposes a solution to the problem with Odysseus’ kingship in the Odyssey by maintaining that Odysseus is not officially considered dead. Consequently, Telemachus cannot inherit the position of king and Penelope must leave Odysseus’ household before remarrying. After discussing the modern concept of legal death and previous interpretations of the Ithacan situation, the paper focusses on Athena's speech at 1.275–92. A close reading demonstrates that erecting a cenotaph to Odysseus would be tantamount to a modern declaration of death (...) in absentia, since it will render Penelope a widow and Telemachus the head of the household. This legal convention chimes with the Homeric depiction of Hades. (shrink)

We develop and defend the thesis that the Hilbert space formalism of quantum mechanics is a new theory of probability. The theory, like its classical counterpart, consists of an algebra of events, and the probability measures defined on it. The construction proceeds in the following steps: (a) Axioms for the algebra of events are introduced following Birkhoff and von Neumann. All axioms, except the one that expresses the uncertainty principle, are shared with the classical event space. The only models for (...) the set of axioms are lattices of subspaces of inner product spaces over a field K. (b) Another axiom due to Soler forces K to be the field of real, or complex numbers, or the quaternions. We suggest a probabilistic reading of Soler's axiom. (c) Gleason's theorem fully characterizes the probability measures on the algebra of events, so that Born's rule is derived. (d) Gleason's theorem is equivalent to the existence of a certain finite set of rays, with a particular orthogonality graph (Wondergraph). Consequently, all aspects of quantum probability can be derived from rational probability assignments to finite "quantum gambles". (e) All experimental aspects of entanglement- the violation of Bell's inequality in particular- are explained as natural outcomes of the probabilistic structure. (f) We hypothesize that even in the absence of decoherence macroscopic entanglement can very rarely be observed, and provide a precise conjecture to that effect .We also discuss the relation of the present approach to quantum logic, realism and truth, and the measurement problem.

In the mid-nineteenth century George Boole formulated his ‘conditions of possible experience’. These are equations and ineqaulities that the relative frequencies of events must satisfy. Some of Boole's conditions have been rediscovered in more recent years by physicists, including Bell inequalities, Clauser Horne inequalities, and many others. In this paper, the nature of Boole's conditions and their relation to propositional logic is explained, and the puzzle associated with their violation by quantum frequencies is investigated in relation to a variety of (...) approaches to the interpretation of quantum mechanics. * While preparing this paper for publication I have learnt of the untimely death of Professor J.

This paper describes how the Electrical and Computer Engineering Department at South Dakota School of Mines and Technology has chosen to integrate ethics into their curriculum. All university freshmen engineering students are introduced to ethics through the presentation of ethical dilemmas. During this exercise, students are forced to argue both sides (‘for’ and ‘against’) of a hypothetical ethical engineering dilemma. It provides a setting for great discussion with the desired outcome that they learn to carefully analyze a situation before they (...) draw conclusions. In the sophomore year, students are introduced to methods to use the fundamental principles, the fundamental canons, and the suggested guidelines for use with the fundamental canons of ethics when analyzing appropriate action to be taken when confronted with ethical dilemmas. We currently use the ‘sophomore’ method for seniors because the sequencing is just beginning. Next year the seniors will do more indepth analysis of ethical case studies. (shrink)

Israel’s discursive strategy for legitimizing the displacement of Palestinians in 1948 involved describing it as part of a regional “population exchange.” This argument contributed to three critical characteristics of Israeli citizenship. First, it solidified an understanding of citizenship as a negation of persecution and a haven for would-be Jewish refugees. Second, it tied Mizrahi claims against states across the Middle East to Palestinian claims against Israel. Israel thus exploited Mizrahi refugee rights for its geostrategic interests—a fight against the claims of (...) Palestinian refugees. This had detrimental material consequences for both groups. Third, this strategy contributed to the construction of Palestinians as an “exchangeable remainder” and a demographic threat that could potentially pose a risk to the Jewish majority. Ultimately, Israel irrevocably entangled the displacement histories of three groups: Ashkenazi Jews, Mizrahi Jews, and Arab Palestinians. This Gordian knot remains with us today, and is reflected in a stratified Israeli society. But the vision that this symposium suggests we consider, that of “historical justice,” demands that it be undone. This Article therefore offers a way in which the refugee histories could perhaps one day be disentangled: a program of reparations for the Mizrahi and Palestinian citizens of Israel. (shrink)

A deterministic model that accounts for the statistical behavior of random samples of identical particles is presented. The model is based on some nonmeasurable distribution of spin values in all directions. The mathematical existence of such distributions is proved by set-theoretical techniques, and the relation between these distributions and observed frequencies is explored within an appropriate extension of probability theory. The relation between quantum mechanics and the model is specified. The model is shown to be consistent with known polarization phenomena (...) and the existence of macroscopic magnetism. Finally..

We argue that certain types of many minds (and many worlds) interpretations of quantum mechanics, e.g. Lockwood ([1996a]), Deutsch ([1985]) do not provide a coherent interpretation of the quantum mechanical probabilistic algorithm. By contrast, in Albert and Loewer's ([1988]) version of the many minds interpretation, there is a coherent interpretation of the quantum mechanical probabilities. We consider Albert and Loewer's probability interpretation in the context of Bell-type and GHZ-type states and argue that it implies a certain (weak) form of nonlocality.

This article deals with the topics of nihilism and technology within the horizon of Western societies. More precisely, we research what is the most determining element in the relationship between nihilism and technology. To develop this research, we seek a concept of nihilism that is integrated into the scenario that emerged after the modern era, therefore integrating not only the 20th century, but also the 21st century. This concept is achieved through consideration of the effects of historicism according to Leo (...) Strauss' analysis in his work Natural Right and History. Next, the issues relating to the control of technology are analyzed and answered through Feenberg's position, which shows different conceptions of what would be considered the philosophy of technology. Finally, the conclusion is that, in the relationship between nihilism and technology, nihilism remains the most determining, because the dimensions specific to historicism still remain integrated and active in the institutions of democratic societies in the 21st century, despite the proposal to invent new institutions made by Feenberg.

We describe a possible physical device that computes a function that cannot be computed by a Turing machine. The device is physical in the sense that it is compatible with General Relativity. We discuss some objections, focusing on those which deny that the device is either a computer or computes a function that is not Turing computable. Finally, we argue that the existence of the device does not refute the Church–Turing thesis, but nevertheless may be a counterexample to Gandy's thesis.
