This paper uses a proof of Gödels theorem, implemented on a computer, to explore how a person or a computer can examine such a proof, understand it, and evaluate its validity. It is argued that, in order to recognize it (1) as Gödel's theorem, and (2) as a proof that there is an undecidable statement in the language of PM, a person must possess a suitable semantics. As our analysis reveals no differences between the processes required by people and machines (...) to understand Gödel's theorem and manipulate it symbolically, an effective way to characterize this semantics is to model the human cognitive system as a Turing Machine with sensory inputs.

L'article thématise la tension entre la compréhension d'une « Écriture sainte » et une philosophie critique « éclairée » dont la position est, au premier chef, représentée par Kant. Pour lui, l'interprétation de l'Écriture obéit uniquement au strict paradigme herméneutique. Il part du fait que l'homme, un être qui n'est pas purement rationnel, mais qui est simultanément raisonnable et soumis aux sens, est moralement obligé de saisir positivement les commandements éthiques fondés dans la raison comme des commandements divins. Pour ce (...) faire, il est « au mieux » préférable d'avoir une Écriture « sainte ». Son caractère « sacré » signifie que son texte reste, face à toute interprétation par une raison finie, ouvert à d'autres interprétations de sorte qu'aucune ne peut se dire définitive. Cela vaut tout particulièrement pour certains passages de l'Écriture qui sont difficiles voire impossibles à comprendre dans l'esprit et l'horizon d'une époque donnée. L'épisode de la tour de Babel et celui du bon Samaritain servent ici d'exemples. Der Aufsatz hat die Spannung zwischen einer kritischen, « aufgeklärten » Philosophie und dem Verstehen einer « Heiligen Schrift » zum Thema. Für die Position kritischen Philosophie steht in erster Linie die Philosophie Kants. Für ihn ist die Schriftauslegung immer noch das hermeneutischen Paradigma schlechthin. Er geht davon aus, daß der Mensch, als ein Wesen, das nicht rein vernünftig, sondern als Vernunftwesen zugleich Sinnenwesen ist, moralisch verpflichtet sei, die in reiner Vernunft begründeten Gebote der Moral positiv als göttliche Gebote aufzufassen. Dazu habe man « am besten » eine « heilige » Schrift. Ihre « Heiligkeit » bedeutet, daβ ihr Text gegenüber jeder Auslegung durch endliche Vernunft stehenbleibt für andere Auslegungen, so daβ keine Interpretation sich als endgültig verstehen kann. Das gilt besonders für Passagen der Schrift, die aus dem Geist und dem Horizont einer bestimmten Zeit schwer oder gar nicht zu verstehen sind. Als Beispiele dienen vor allem die Schriftstellen vom Turmbau zu Babel und vom barmherzigen Samariter. (shrink)
We prove (Proposition 2.1) that if $\mu$ is a generically stable measure in an NIP (no independence property) theory, and $\mu(\phi(x,b))=0$ for all $b$ , then for some $n$ , $\mu^{(n)}(\exists y(\phi(x_{1},y)\wedge \cdots \wedge\phi(x_{n},y)))=0$ . As a consequence we show (Proposition 3.2) that if $G$ is a definable group with fsg (finitely satisfiable generics) in an NIP theory, and $X$ is a definable subset of $G$ , then $X$ is generic if and only if every translate of $X$ does not (...) fork over $\emptyset$ , precisely as in stable groups, answering positively an earlier problem posed by the first two authors.

We show that the variety of n -dimensional weakly higher order cylindric algebras, introduced in Németi [9], [8], is finitely axiomatizable when n > 2. Our result implies that in certain non-well-founded set theories the finitization problem of algebraic logic admits a positive solution; and it shows that this variety is a good candidate for being the cylindric algebra theoretic counterpart of Tarski’s quasi-projective relation algebras.
The thirty-three essays in <I>Relativism: A Contemporary Anthology</I> grapple with one of the most intriguing, enduring, and far-reaching philosophical problems of our age. Relativism comes in many varieties. It is often defined as the belief that truth, goodness, or beauty is relative to some context or reference frame, and that no absolute standards can adjudicate between competing reference frames. Michael Krausz's anthology captures the significance and range of relativistic doctrines, rehearsing their virtues and vices and reflecting on a spectrum of (...) attitudes. Invoking diverse philosophical orientations, these doctrines concern conceptions of relativism in relation to facts and conceptual schemes, realism and objectivity, universalism and foundationalism, solidarity and rationality, pluralism and moral relativism, and feminism and poststructuralism. Featuring nine original essays, the volume also includes many classic articles, making it a standard resource for students, scholars, and researchers. <B>Table of Contents:</B> Foreword by Alan Ryan Preface Introduction Michael Krausz <B>Part I.

E. Schrödinger's ideas on interpreting quantum mechanics have been recently re-examined by historians and revived by philosophers of quantum mechanics. Such recent re-evaluations have focused on Schrödinger's retention of space–time continuity and his relinquishment of the corpuscularian understanding of microphysical systems. Several of these historical re-examinations claim that Schrödinger refrained from pursuing his 1926 wave-mechanical interpretation of quantum mechanics under pressure from the Copenhagen and Göttingen physicists, who misinterpreted his ideas in their dogmatic pursuit of the complementarity doctrine and the (...) principle of uncertainty. My analysis points to very different reasons for Schrödinger's decision and, accordingly, to a rather different understanding of the dialogue between Schrödinger and N. Bohr, who refuted Schrödinger's arguments. Bohr's critique of Schrödinger's arguments predominantly focused on the results of experiments on the scattering of electrons performed by Bothe and Geiger, and by Compton and Simon. Although he shared Schrödinger's rejection of full-blown classical entities, Bohr argued that these results demonstrated the corpuscular nature of atomic interactions. I argue that it was Schrödinger's agreement with Bohr's critique, not the dogmatic pressure, which led him to give up pursuing his interpretation for 7 yr. Bohr's critique reflected his deep understanding of Schrödinger's ideas and motivated, at least in part, his own pursuit of his complementarity principle. However, in 1935 Schrödinger revived and reformulated the wave-mechanical interpretation. The revival reflected N. F. Mott's novel wave-mechanical treatment of particle-like properties. R. Shankland's experiment, which demonstrated an apparent conflict with the results of Bothe–Geiger and Compton–Simon, may have been additional motivation for the revival. Subsequent measurements have proven the original experimental results accurate, and I argue that Schrödinger may have perceived even the reformulated wave-mechanical approach as too tenuous in light of Bohr's critique.

Employee volunteerism can be an effective strategy for increasing the effectiveness of corporate philanthropy. However, in order to be effective, volunteer initiatives should be directed by the firm to ensure a strategic fit and focus on the core competencies of the firm. Therefore, internal marketing strategies are needed to ensure managers receive employee support. Our research quantitatively extends research by Peloza and Hassay {journal of Business Ethics 64(4), 357-379, 2006) who argued that employee volunteerism is motivated by egoistic, altruistic and (...) organizational citizenship motives. Our findings suggest that volunteer opportunities that fulfill egoistic and organizational citizenship motives will be effective, but that the altruistic motive is not significant. We also find that formal policies concerning manager recognition or time off are not effective, providing more discretion for individual managers. Implications for managers seeking to increase the effectiveness (and therefore support the business case) of their corporate philanthropy are discussed. (shrink)
The possible role of the neurotransmitter serotonin in human affiliative behavior is under-examined in the review by Depue & Morrone-Strupinsky (D&M-S). This commentary reviews evidence indicating that serotonin not only inhibits aggressive behavior that may be detrimental to affiliative bonds with others in a social group but serotonin also enhances prosocial behaviors that may facilitate ties to the social group.
Physicians make some medical decisions without disclosure to their patients. Nondisclosure is possible because these are silent decisions to refrain from screening, diagnostic or therapeutic interventions. Nondisclosure is ethically permissible when the usual presumption that the patient should be involved in decisions is defeated by considerations of clinical utility or patient emotional and physical well-being. Some silent decisions - not all - are ethically justified by this standard. Justified silent decisions are typically dependent on the physician's professional judgment, experience and (...) knowledge, and are not likely to be changed by patient preferences. We condemn the inappropriate exclusion of the patient from the decision-making process. However, if a test or treatment is unlikely to yield a net benefit, disclosure and discussion are at times unnecessary. Appropriate silent decisions are ethically justified by such considerations as patient benefit or economy of time. (shrink)
Background Continued advances in human microbiome research and technologies raise a number of ethical, legal, and social challenges. These challenges are associated not only with the conduct of the research, but also with broader implications, such as the production and distribution of commercial products promising maintenance or restoration of good physical health and disease prevention. In this article, we document several ethical, legal, and social challenges associated with the commercialization of human microbiome research, focusing particularly on how this research is (...) mobilized within economic markets for new public health uses. Methods We conducted in-depth, semi-structured interviews (2009–2010) with 63 scientists, researchers, and National Institutes of Health project leaders (“investigators”) involved with human microbiome research. Interviews explored a range of ethical, legal, and social dimensions of human microbiome research, including investigators’ perspectives on commercialization. Using thematic content analysis, we identified and analyzed emergent themes and patterns. Results Investigators discussed the commercialization of human microbiome research in terms of (1) commercialization, probiotics, and issues of safety, (2) public awareness of the benefits and risks of dietary supplements, and (3) regulation. Conclusion The prevailing theme of ethical, legal, social concern focused on the need to find a balance between the marketplace, scientific research, and the public’s health. The themes we identified are intended to serve as points for discussions about the relationship between scientific research and the manufacture and distribution of over-the-counter dietary supplements in the United States.

The classical theory of preference among monetary bets represents people as expected utility maximizers with concave utility functions. Critics of this account often rely on assumptions about preferences over wide ranges of total wealth. We derive a prediction of the theory that bears on bets at any fixed level of wealth, and test the prediction behaviorally. Our results are discrepant with the classical account. Competing theories are also examined in light of our data.
Students, the future Information and Communication Technology (ICT) professionals, are often perceived to have little understanding of the ethical issues associated with the use of ICTs. There is a growing recognition that the moral issues associated with the use of the new technologies should be brought to the attention of students. Furthermore, they should be encouraged to explore and think more deeply about the social and legal consequences of the use of ICTs. This paper describes the development of a tool (...) designed to raise students’ awareness of the social impact of ICTs. The tool offers guidance to students undertaking computing and computer-related courses when considering the social, legal and professional implications of the actions of participants in situations of ethical conflict. However, unlike previous work in this field, this tool is not based on an artificial intelligence paradigm. Aspects of the theoretical basis for the design of the tool and the tool’s practical development are discussed. Preliminary results from the testing of the tool are also discussed. (shrink)
In 1953 a young female Japanese macaque called Imo began washing sweet potatoes before eating them, presumably to remove dirt and sand grains. Soon other monkeys had adopted this behaviour, and potato washing gradually spread throughout the troop. When, three years after her first invention, Imo devised a second novel foraging behaviour, that of separating wheat from sand by throwing mixed handfuls into water and scooping out the floating grains, she was almost instantly heralded around the world as a 'monkey (...) genius'. Imo is probably the most celebrated of animal innovators. In fact, many animals will invent new behaviour patterns, adjust established behaviours to a novel context, or respond to stresses in an appropriate and novel manner. -/- Innovation is an important component of behavioural flexibility, vital to the survival of individuals in species with generalist or opportunistic lifestyles, and potentially of critical importance to those endangered or threatened species forced to adjust to changed or impoverished environments. Innovation may also have played a central role in avian and primate brain evolution. Yet until recently animal innovation has been subject to almost complete neglect by behavioural biologists, psychologists, social learning researchers, and conservation-minded biologists. -/- This collection of stimulating and readable articles by leading scientific authorities is the first ever book on 'animal innovation', designed to put the topic of animal innovation on the map and heighten awareness of this developing field.

The phenomenology of auditory verbal hallucinations (AVHs) occurring in hypnagogic and hypnopompic (H&H) states has received little attention. In a sample of healthy participants ( N = 325), 108 participants reported H&H AVHs and answered subsequent questions on their phenomenology. AVHs in the H&H state were found (1) to be more likely to only feature the occasional clear word than to be clear, (2) to be more likely (...) to be one-off voices than to be recurrent voices, (3) to be more likely to be voices of people known to the individual than unknown persons, (4) to be more likely to talk directly to the person rather than not, and (5) to only rarely give commands, ask questions, or to result in an interactive conversation. Their phenomenology was similar to normative AVHs in wakefulness (as established by previous research) in that the voice-hearer was usually the target of the voice, and the voice was more likely to be of a recognized person. However, H&H AVHs differed from AVHs in wakefulness in that commands and questions were rare, and there was typically no dialogical engagement with the voice. We conclude by proposing that two distinct types of H&H AVHs may exist (which we term “dialogic” and “monologic”), based on an analysis of the phenomenology of the experience, and suggest avenues for future research.

The ability to reason independently from one's own goals or beliefs has long been recognised as a key characteristic of the development of formal operational thought. In this article we present the results of a study that examined the correlates of this ability in a group of 10-year-old children ( N = 61). Participants were presented with conditional and relational reasoning items, where the content was manipulated such that the conclusion to the arguments were either congruent, neutral, or incongruent with (...) beliefs, and either logically valid or logically invalid. Participants also received a measure of working memory capacity (the counting span task) and a measure of inhibitory control (the stop signal task). Indices of belief bias and logical reasoning on belief-based problems were predicted independently by both measures. In contrast logical reasoning on belief neutral problems was predicted by working memory alone. The findings suggest that executive functions play a key role in the development of children's ability to decontextualise their thinking. (shrink)
This article presents a trope bundle theory of simple substances, the Strong Nuclear Theory[SNT] building on the schematic basis offered by Simons's (1994) Nuclear Theory[NT]. The SNT adopts Ellis's (2001) dispositional essentialist conception of simple substances as powerful particulars: all of their monadic properties are dispositional. Moreover, simple substances necessarily belong to some natural kind with a real essence formed by monadic properties. The SNT develops further the construction of substances the NT proposes to obtain an adequate trope bundle theory (...) of powerful particulars. The SNT allows for co-located powerful particulars. However, every powerful particular is necessarily co-located with its constituent tropes, which determine its causal powers. Every constituent trope of substance i is part of a trope aggregate (the n-bundle or c-bundle) that forms an individual figuring in the basic spatio-temporal relations. The location of these individuals determines the location of individual tropes. Since they are necessarily co-located with substance i when they exist, every trope t of i is necessarily co-located with i when it exits. Every simple substance has nuclear tropes necessary to it. It belongs to certain primary natural kind K because its nuclear tropes belong to certain distinct determinate kinds. (shrink)

Despite its lack of influence in analytical philosophy, and independently of its content as a process philosophy, Whitehead's system in Process and Reality affords a valuable lesson on how to pursue revisionary systematic metaphysics. This paper argues the case generally for metaphysical revision and system, describes the structure of Whitehead's categorial scheme, endorses his idea of an ultimate which is not an entity, and outlines an alternative, “digital” ultimate or basis composed of several analytical factors. [I]n the absence of a (...) well-defined categoreal scheme of entities, issuing in a satisfactory metaphysical system, every premise in a philosophical argument is under suspicion. (shrink)
Martyrdom has played and continues to play a dominant role in the religious imagination of many. Jews and Christians alike conceive of their martyrs as exceptional people of faith who express exceptional love and devotion to God. The purpose of this paper is to explore some of the conceptual features of martyrdom by virtue of which it has its role and to show, using those very features and using Simone Weil's observations, that martyrdom cannot mark the logical climax of the (...) believer's love of God.

«Weizsäcker et les autres »Merleau-Ponty lecteur du GestaltkreisConçu comme un élément de l’essai « Percezione, corpo e movimento. L’estetica antropologia dell’espressione nell’inedito Le monde sensible et le monde de l’expression di Maurice Merleau-Ponty » (publié dans le n° 12 de Chiasmi international), le texte « Weizsäcker et les autres » examine la plus importante – et la moins reconnue – des dettes théoriques merleau-pontiennes. Cette source « occultée » recouvre le rôle important dans l’encadrement des questions de l’expression et du (...) mouvement dans la philosophie merleau-pontienne. En approfondissant les consonances théoriques entre certains chapitres centraux de la Phénoménologie de la perception, Le monde sensible et le monde de l’expression et Der Gestaltkreis de Viktor von Weizsäcker, nous avancerons l’hypothèse d’une connaissance approfondie de la part de Merleau-Ponty du texte cardinal de l’anthropologie médicale des années quarante.“Weizsäcker et les autres”Merleau-Ponty reads the GestaltkreisConceived as a part of the essay “Percezione, corpo e movimento. L’estetica antropologia dell’espressione nell’inedito Le monde sensible et le monde de l’expression di Maurice Merleau-Ponty” (published in Chiasmi International, no. 12), the text of “Weizsäcker and the Others” examines the most important – least recognized – of Merleau-Ponty’s theoretical debts. This “concealed” source covers Weizsäcker’s important role in the framing of questions of expression and movement in Merleau-Ponty’s philosophy. By treating in depth the theoretical resonances between certain central chapters of The Phenomenology of Perception, Le monde sensible et le monde de l’expression (The Sensible World and the World of Expression), and Viktor von Weizsäcker’s Der Gestaltkreis, we will advance the hypothesis that Merleau-Ponty had a profound knowledge of the cardinal text of medical anthropology of the 1940s.
