The Economy of Certainty: An Introduction to the Typology of Islamic Legal Theory. By Aron Zysow. Resources in Arabic and Islamic Studies, vol. 2. Atlanta: Lockwood Press, 2013. Pp. xxviii + 330. $32.95.

Kitap, Aron Zysow’un Harvard Üniversitesinde 1984 yılında sunmuş olduğu doktora tezinin geliştirilerek yayımlanmış halidir. Sunumunun üzerinden yaklaşık otuz yıl gibi uzunca bir süre geçtikten sonra yayımlanmıştır. Ancak yayımlanmasının bu kadar gecikmiş olması, tezin, fıkıh usûlü ve kelâm alanlarında batıda yapılan akademik çalışmalar üzerindeki katkısını ve etkisini azaltmış değildir. Kitap hakkında alan indekslerinde taranan dergilerde pek çok kitap kritiği yazılmış olması da bu etkinin göstergelerindendir.

The phenomenon of base-rate neglect has elicited much debate. One arena of debate concerns how people make judgments under conditions of uncertainty. Another more controversial arena concerns human rationality. In this target article, we attempt to unpack the perspectives in the literature on both kinds of issues and evaluate their ability to explain existing data and their conceptual coherence. From this evaluation we conclude that the best account of the data should be framed in terms of a dual-process model of (...) judgment, which attributes base-rate neglect to associative judgment strategies that fail to adequately represent the set structure of the problem. Base-rate neglect is reduced when problems are presented in a format that affords accurate representation in terms of nested sets of individuals. (shrink)

The paper presents and defends a Bayesian theory of trust in social networks. In the first part of the paper, we provide justifications for the basic assumptions behind the model, and we give reasons for thinking that the model has plausible consequences for certain kinds of communication. In the second part of the paper we investigate the phenomenon of overconfidence. Many psychological studies have found that people think they are more reliable than they actually are. Using a simulation environment that (...) has been developed in order to make our model computationally tractable we show that in our model inquirers are indeed sometimes better off from an epistemic perspective overestimating the reliability of their own inquiries. We also show, by contrast, that people are rarely better off overestimating the reliability of others. On the basis of these observations we formulate a novel hypothesis about the value of overconfidence. (shrink)

It is currently common practice in social and business research, to lift concepts and theories from one country context—and extending the validity of the results—using them in another. This paper discusses the question relating to such generalisability in the context of global, innovative industries. Statistical methods are applied to compare results of a quantitative investigation of firm life-cycle theory between two developed countries. Such comparison implemented with statistical rigour on a quantitative basis is not common, and difficult to execute. Results (...) show that even though life-cycle theory has been found meaningful and valid on both country-specific populations, the quantitative comparison of these results has highlighted a substantial amount of statistically significant differences. This leads to the conclusion that extension of social theory between various country contexts needs to consider a variety of contextual parameters, cautioning computer scientists offering solutions to various problems around the world coming from their own, unique, country-specific perspectives to keep an open mind.

The paper examines a widely discussed passage in Diodorus’ Historical Library that describes the development of the social structure of the Lipari Islands. By reconstructing the history of research, terminological ambiguities are identified, forming the basis for a reinterpretation of the passage. It is demonstrated that the Liparensians implemented specific institutional orders, continually adapting to the demands of their surroundings, yet always aware of the impact and consequences of their actions.

Aron Gurwitsch (1901-1973) est surtout connu du public fancophone par son ouvrage de 1957: Theorie du champ de la conscience. C'est la periode parisienne (de l'automne 1933 au printemps 1940) de Gurwitsch que le present volume documente tres precisement: il presente d'abord pour la premiere fois, les resultats substantiels d'un ouvrage en gestation qui n'aura pas vu le jour du vivant de l'auteur et qui rassemble, sous le titre Esquisse de la phenomenologie constitutive, les materiaux des cours et conferences (...) sur la Gestaltpsychologie, la psychologie intentionaliste, la phenomenologie de l'ideation, l'introduction a la phenomenologie. Le present volume rassemble aussi, a titre d'Appendice, quelques uns des articles publies par Aron Gurwitsch lors de cette periode parisienne. L'ensemble de ces travaux constitue un temoignage inedit sur une des toutes premieres introductions a la phenomenologie husserlienne, dans son veritable contexte de probleme. (shrink)

Performing surgery in the developing world presents unique challenges and dilemmas for the visiting physician from an industrialized country. Language barriers, widespread, profound pathology, and lack of adequate facilities are obvious hurdles. A more subtle problem, though every bit as significant, is that the principles and procedures we routinely utilize at home to uphold ethical standards of care and to aid us in decision-making are often poorly applicable in the developing world. Acknowledging that cultural factors play a primary role in (...) every aspect of their interaction with patients, physicians must scrutinize and even modify the tools they employ when attempting to deliver ethical care in foreign ..

Interoception in the broader sense refers to the perception of internal states, including the perception of the actual state of the internal organs and the motor system. Dimensions of interoception include interoceptive accuracy, i.e., the ability to sense internal changes assessed with behavioral tests, confidence rating with respect to perceived performance in an actual behavioral test, and interoceptive sensibility, i.e., the self-reported generalized ability to perceive body changes. The relationship between dimension of cardioceptive and proprioceptive modalities and their association with (...) affect are scarcely studied. In the present study, undergraduate students filled out questionnaires assessing positive and negative affect, interoceptive sensibility, and body competence. Following this, they completed a behavioral task assessing cardioceptive accuracy and two tasks assessing proprioceptive accuracy with respect to the tension of arm flexor muscles and the angular position of the elbow joint. Confidence ratings were measured with visual analog scales after the tasks. With the exception of a weak association between cardioceptive accuracy and the respective confidence rating, no associations between and within modalities were found with respect to various dimensions of interoception. Further, the interoceptive dimensions were not associated with state and trait positive and negative affect and perceived body competence. In summary, interoceptive accuracy scores do not substantially contribute to conscious representations of cardioceptive and proprioceptive ability. Within our data, non-pathological affective states are not associated with the major dimensions of interoception for the cardiac and proprioceptive modalities. (shrink)

What does it mean for an agent faced with choice under uncertainty to “know” something? While a variety of mathematical methods are available to construct formal models to answer this question, the combination of different approaches may lead to unsettling paradoxes. I propose a unified theory that eliminates such inconsistencies by relying on a sharp conceptual distinction between information the decision-maker observes and how much of that information she can cognitively process. The resulting model allows for natural decision-theoretic characterizations of (...) comparing different amounts of information. (shrink)

The commentaries indicate a general agreement that one source of reduction of base-rate neglect involves making structural relations among relevant sets transparent. There is much less agreement, however, that this entails dual systems of reasoning. In this response, we make the case for our perspective on dual systems. We compare and contrast our view to the natural frequency hypothesis as formulated in the commentaries.

1. Although a number of personality variables have been identified by various authors as the determinants of religious behavior, independent of specific religious denomination, the results of the studies under consideration certainly appear to be inconsistent with such claims. It is suggested instead that the personality correlates of religious behavior vary with the specific religious denomination. 2. For most people religious belief and religious observance are acquired or learned in the socialization process. In a culture in which there is no (...) social pressure to conform in relation to religious behavior , individual differences in adult religious behavior may be a result of certain personality differences. In the Israeli Jewish sample a number of personality variables were found to covary with religious belief and/or observance. Religious belief and observance, however, were also highly significant sources of variance in subjects' values. These value differences probably influence the what and how of the socialization process which in turn may be responsible for some-although probably not all-of the personality variables associated with religious behavior. 3. In cultures which are characterized by strong social pressure in relation to religious conformity, e. g. the culture represented by our United States Protestant sample, the religious behavior of many individuals will be a result of their need to conform rather than other personality variables directly related to their religious behavior as such. Thus in the United States Protestant sample conformity and variables associated with it were the only significant sources of variance in subjects' religious behavior. The results of our studies indicate the importance of differentiating between religious belief and observance which is merely the result of social conformity and religious belief and observance which is also the result of other variables which are more directly related to religious behavior as such. Presently we are in the process of constructing instruments to measure these two types of religious behavior. 4. Finally, it is suggested that in trying to discover the determinants of individual differences in religious behavior there has been too much emphasis on motivational variables and not enough on environmental factors. A social learning model may be the best suited for the investigation of the sources of individual differences in religious behavior. (shrink)

Traditional Bayesianism requires that an agent’s degrees of belief be represented by a real-valued, probabilistic credence function. However, in many cases it seems that our evidence is not rich enough to warrant such precision. In light of this, some have proposed that we instead represent an agent’s degrees of belief as a set of credence functions. This way, we can respect the evidence by requiring that the set, often called the agent’s credal state, includes all credence functions that are in (...) some sense compatible with the evidence. One known problem for this evidentially motivated imprecise view is that in certain cases, our imprecise credence in a particular proposition will remain the same no matter how much evidence we receive. In this article I argue that the problem is much more general than has been appreciated so far, and that it’s difficult to avoid it without compromising the initial evidentialist motivation. _1_ Introduction _2_ Precision and Its Problems _3_ Imprecise Bayesianism and Respecting Ambiguous Evidence _4_ Local Belief Inertia _5_ From Local to Global Belief Inertia _6_ Responding to Global Belief Inertia _7_ Conclusion.

According to the Argument from Disagreement (AD) widespread and persistent disagreement on ethical issues indicates that our moral opinions are not influenced by moral facts, either because there are no such facts or because there are such facts but they fail to influence our moral opinions. In an innovative paper, Gustafsson and Peterson (Synthese, published online 16 October, 2010) study the argument by means of computer simulation of opinion dynamics, relying on the well-known model of Hegselmann and Krause (J Artif (...) Soc Soc Simul 5(3):1–33, 2002; J Artif Soc Soc Simul 9(3):1–28, 2006). Their simulations indicate that if our moral opinions were influenced at least slightly by moral facts, we would quickly have reached consensus, even if our moral opinions were also affected by additional factors such as false authorities, external political shifts and random processes. Gustafsson and Peterson conclude that since no such consensus has been reached in real life, the simulation gives us increased reason to take seriously the AD. Our main claim in this paper is that these results are not as robust as Gustafsson and Peterson seem to think they are. If we run similar simulations in the alternative Laputa simulation environment developed by Angere and Olsson (Angere, Synthese, forthcoming and Olsson, Episteme 8(2):127–143, 2011) considerably less support for the AD is forthcoming.

Leo Strauss’ controversial theory of esoteric philosophy, as presented in Persecution and the Art of Writing, sparked a fierce debate. Opponents and proponents of the theory utilised a wide range of perspectives to support their arguments. By investigating esoteric philosophy from a sociolinguistic perspective, this paper introduces a novel perspective to the Strauss dispute. In PAW Strauss is mistaken regarding esotericism and its role in philosophy. On one hand it is reasonable to endorse Strauss’ persuasive account on the origins of (...) esoteric writing. The Straussian account provides a plausible sociological background as to why philosophy, per se became an esoteric fliedH. On the other hand it seems as Strauss ascribed undue significance to possible clandestine massages that may be found within works of philosophy because philosophy is mostly already done in an esoteric linguistic space.

By age 85, most adults manifest some degree of motor impairment. However, in most individuals a specific etiology for motor decline and treatment to modify its inexorable progression cannot be identified. Recent clinical-pathologic studies provide evidence that mixed-brain pathologies are commonly associated with late-life motor impairment. Yet, while nearly all older adults show some degree of accumulation of Alzheimer’s disease and related dementias pathologies, the extent to which these pathologies contribute to motor decline varies widely from person to person. Slower (...) or faster than expected motor decline in the presence of brain injury and/or pathology has been conceptualized as more or less “resilience” relative to the average person This suggests that other factors, such as lifestyles or other neurobiologic indices may offset or exacerbate the negative effects of pathologies via other molecular pathways. The mechanisms underlying neural motor resilience are just beginning to be illuminated. Unlike its cousin, cognitive resilience which is restricted to neural mechanisms above the neck, the motor system extends the total length of the CNS and beyond the CNS to reach muscle and musculoskeletal structures, all of which are crucial for motor function. Building on prior work, we propose that by isolating motor decline unrelated to neuropathologies and degeneration, investigators can identify genes and proteins that may provide neural motor resilience. Elucidating these molecular mechanisms will advance our understanding of the heterogeneity of late-life motor impairment. This approach will also provide high value therapeutic targets for drug discovery of therapies that may offset the negative motor consequences of CNS pathologies that are currently untreatable.
