I discuss the attitude of Jewish law sources from the 2nd–:5th centuries to the imprecision of measurement. I review a problem that the Talmud refers to, somewhat obscurely, as impossible reduction. This problem arises when a legal rule specifies an object by referring to a maximized measurement function, e.g., when a rule applies to the largest part of a divided whole, or to the first incidence that occurs, etc. A problem that is often mentioned is whether there might be hypothetical (...) situations involving more than one maximal value of the relevant measurement and, given such situations, what is the pertinent legal rule. Presumption of simultaneous occurrences or equally measured values are also a source of embarrassment to modern legal systems, in situations exemplified in the paper, where law determines a preference based on measured values. I contend that the Talmudic sources discussing the problem of impossible reduction were guided by primitive insights compatible with fuzzy logic presentation of the inevitable uncertainty involved in measurement. I maintain that fuzzy models of data are compatible with a positivistic epistemology, which refuses to assume any precision in the extra-conscious world that may not be captured by observation and measurement. I therefore propose this view as the preferred interpretation of the Talmudic notion of impossible reduction. Attributing a fuzzy world view to the Talmudic authorities is meant not only to increase our understanding of the Talmud but, in so doing, also to demonstrate that fuzzy notions are entrenched in our practical reasoning. If Talmudic sages did indeed conceive the results of measurements in terms of fuzzy numbers, then equality between the results of measurements had to be more complicated than crisp equations. The problem of impossible reduction could lie in fuzzy sets with an empty core or whose membership functions were only partly congruent. Reduction is impossible may thus be reconstructed as there is no core to the intersection of two measures. I describe Dirichlet maps for fuzzy measurements of distance as a rough partition of the universe, where for any region A there may be a non-empty set of - _A, where the problem of impossible reduction applies. This model may easily be combined with probabilistic extention. The possibility of adopting practical decision standards based on -cuts is discussed in this context. I propose to characterize the uncertainty that was presumably capped by the old sages as U- uncertainty, defined, for a non-empty fuzzy set A on the set of real numbers, whose -cuts are intervals of real numbers, as U = 1/h 0 h log [1+]d, where h is the largest membership value obtained by any element of A and is the measure of the -cut of A defined by the Lebesge integral of its characteristic function.

This study examined ethical attitudes and perceptions of 691 undergraduate seniors and freshmen in a college of business. Gender was found to be correlated to perceptions of "what the ethical climate should be" with female subjects showing significantly more favorable attitude towards ethical behaviors than males. Further, Seniors had a more cynical view of the current ethical climate than freshmen. Freshmen were significantly more likely than seniors to believe that good business ethics is positively related to successful business outcomes. Ethical (...) education was significantly correlated to both perceptions of "current ethical climate" as well as "what the ethical climate should be". Students who had been exposed to ethical issues in a course were more likely to believe both, that ethical behavior is, and should be, positively associated with successful business outcomes.

A "wrongful life" suit is based on the purported tortious liability of a genetic counsellor towards an infant with hereditary defects, with the latter asserting that he or she would not have been born at all if not for the counsellor's negligence. This negligence allegedly lies in the failure on the part of the defendant adequately to advice the parents or to conduct properly the relevant testing and thereby prevent the child's conception or birth. This paper will offer support for (...) the thesis that it would be both feasible and desirable to endorse "wrongful life" compensation actions. The genetic counsellor owed a duty of due professional care to the impaired newborn who now claims that but for the counsellor's negligence, he or she would not have been born at all. The plaintiff's defective life constitutes a compensable injury. A sufficient causal link may exist between the plaintiff's injury and the defendant's breach of duty of due professional care and an appropriate measure of damages can be allocated to the disabled newborn. Sanctioning a "wrongful life" cause of action does not necessarily entail abandoning valuable constraints with regard to abortion and euthanasia. Nor does it inevitably lead to an uncontrolled slide down a "slippery slope". (shrink)

Competition among scientists for funding, positions and prestige, among other things, is often seen as a salutary driving force in U.S. science. Its effects on scientists, their work and their relationships are seldom considered. Focus-group discussions with 51 mid- and early-career scientists, on which this study is based, reveal a dark side of competition in science. According to these scientists, competition contributes to strategic game-playing in science, a decline in free and open sharing of information and methods, sabotage of others’ (...) ability to use one’s work, interference with peer-review processes, deformation of relationships, and careless or questionable research conduct. When competition is pervasive, such effects may jeopardize the progress, efficiency and integrity of science. (shrink)

How should deontological theories that prohibit actions of type K — such as intentionally killing an innocent person — deal with cases of uncertainty as to whether a particular action is of type K? Frank Jackson and Michael Smith, who raise this problem in their paper "Absolutist Moral Theories and Uncertainty" (2006), focus on a case where a skier is about to cause the death of ten innocent people — we don’t know for sure whether on purpose or not — (...) by causing an avalanche; and we can only save the people by shooting the skier. One possible deontological attitude towards such uncertainty is what Jackson and Smith call the threshold view, according to which whether or not the deontological constraint applies depends on our degree of (justified) certainty meets a given threshold. Jackson and Smith argue against the threshold view that it leads to implausible paradoxical moral dilemmas in a special kind of case. In this response, we show that the threshold view can avoid these implausible moral dilemmas, as long as the relevant deontological constraint is grounded in individualistic patient-based considerations, such as what an individual person is entitled to object to.

In this book Ron Amundson examines two hundred years of scientific views on the evolution-development relationship from the perspective of evolutionary developmental biology. This perspective challenges several popular views about the history of evolutionary thought by claiming that many earlier authors had made history come out right for the Evolutionary Synthesis. The book starts with a revised history of nineteenth-century evolutionary thought. It then investigates how development became irrelevant with the Evolutionary Synthesis. It concludes with an examination of the contrasts (...) that persist between mainstream evolutionary theory and evo-devo. This book will appeal to students and professionals in the philosophy and history of science, and biology. (shrink)

Many aspects relating to the conduct of mediation are left to mediator choice, but mediators often lack adequate guidance on how their discretion ought to be exercised. In this book, Omer Shapira identifies the ethical norms that govern mediators' conduct. Adopting a professional ethics perspective on the basis of role-morality and applying it to a core definition of mediators' role, Shapira argues that all mediators are placed in ethical relationships with mediation parties, the mediation profession, the public, and (...) their employers or principals that produce ethical obligations.

In this book, best-selling author and mathematician Haim Shapira presents an introduction to mathematical theories which deal with the most beautiful concept ever invented by humankind: infinity. Written in clear, simple language and aimed at a lay audience, this book also offers some strategies that will allow readers to try their ability at solving truly fascinating mathematical problems. Infinity is a deeply counter-intuitive concept that has inspired many great thinkers. In this book we will meet many sages, both familiar (...) and unfamiliar: Zeno and Pythagoras, Georg Cantor and Bertrand Russell, Sofia Kovalevskaya and Emmy Noether, al-Khwarizmi and Euclid, Sophie Germain and Srinivasa Ramanujan. The world of infinity is inhabited by many paradoxes, and so is this book: Zeno paradoxes, Hilbert's "Infinity Hotel", Achilles and the gods paradox, the paradox of heaven and hell, the Ross-Littlewood paradox involving tennis balls, the Galileo paradox and many more. Aimed at the curious but non-technical reader, this book refrains from using any fearsome mathematical symbols. It uses only the most basic operations of mathematics: adding, subtracting, multiplication, division, powers and roots - that is all. But that doesn't mean that a bit of deep thinking won't be necessary and rewarding. Writing with humour and lightness of touch, Haim Shapira banishes the chalky pallor of the schoolroom and offers instead a truly thrilling intellectual journey. Fasten your seatbelt - we are going to Infinity, and beyond! (shrink)

This book provides new perspectives on endurance sport and how it contributes to a good and sustainable life in times of climate change, ecological disruption and inconvenient truths. It builds on a continental philosophical tradition, i.e. the philosophy of among others Peter Sloterdijk, but also on “ecosophy” and American pragmatism to explore the idea of sport as a voluntary attempt to overcome unnecessary obstacles. Since ancient times, human beings have been involved in practices of the Self in order to work (...) on themselves and improve themselves, for instance by strengthening their physical condition and performance through sport. In the contemporary world, millions of individuals engage in endurance sports such as running, swimming and cycling, to get or keep themselves in shape. This study focuses on the ethical dimension of long-distance sport, notably cycling, as a way to become better citizens, but also to contribute to a more sustainable society and healthier planet. Dominant world-views are challenged and an alternative vision is presented. Discourse analysis and conceptual analysis are combined with phenomenology and self-observations of a dedicated practitioner of endurance sport. This book is a great source for philosophers, sport philosophers, environmental philosophers, sport scientists, policy makers, sport journalists, and endurance sport practitioners. (shrink)

Since the publication of Alasdair MacIntyre’s After Virtue in 1981, tensions inherent to the relationship between morally educative practices and the institutions that house them have been widely noted. We propose a taxonomy of the ways in which the pursuit of external goods by institutions undermines the pursuit of the internal goods of practices. These comprise substitution, where the institution replaces the pursuit of one type of good by another; frustration, where opportunities for practitioners to discover goods or develop new (...) standards of excellence are frustrated by institutional priorities and resource allocation; and injustice, which undermines the integrity of relationships within the organization and/or with partners. These threats, though analytically distinct, are often mutually reinforcing. This conceptual contribution is illustrated both by the extant literature and by a novel context, the three-ring circus.

When Dharma Master Heng Shun called to invite me to speak, he didn’t tell me that I was supposed to speak on the interior life. If he had, I would have said no, because here we have so many experts on the interior life, who are real professionals. I think that’s one of the great contributions of Buddhism to the world. It is a professional curriculum in the interior life. Although we have explorers of the interior life in the West, (...) too, I don’t think there’s the same kind of systematic dedication to that exploration as there was in ancient India and in particular in Buddhism.

We present a skill learning model CLARION. Different from existing models of high-level skill learning that use a topdown approach (that is, turning declarative knowledge into procedural knowledge), we adopt a bottom-up approach toward low-level skill learning, where procedural knowledge develops first and declarative knowledge develops later. CLAR- ION is formed by integrating connectionist, reinforcement, and symbolic learning methods to perform on-line learning. We compare the model with human data in a minefield navigation task. A match between the model and (...) human data is found in several respects. (shrink)

The so-called "adaptationism" of mainstream evolutionary biology has been criticized from a variety of sources. One, which has received relatively little philosophical attention, is developmental biology. Developmental constraints are said to be neglected by adaptationists. This paper explores the divergent methodological and explanatory interests that separate mainstream evolutionary biology from its embryological and developmental critics. It will focus on the concept of constraint itself; even this central concept is understood differently by the two sides of the dispute.

This article explicates the interaction between implicit and explicit processes in skill learning, in contrast to the tendency of researchers to study each type in isolation. It highlights various effects of the interaction on learning (including synergy effects). The authors argue for an integrated model of skill learning that takes into account both implicit and explicit processes. Moreover, they argue for a bottom-up approach (first learning implicit knowledge and then explicit knowledge) in the integrated model. A variety of qualitative data (...) can be accounted for by the approach. A computational model, CLARION, is then used to simulate a range of quantitative data. The results demonstrate the plausibility of the model, which provides a new perspective on skill learning. (PsycINFO Database Record (c) 2012 APA, all rights reserved). (shrink)

This paper argues for an explanation of the mechanistic (computational) basis of consciousness that is based on the distinction between localist (symbolic) representation and distributed representation, the ideas of which have been put forth in the connectionist literature. A model is developed to substantiate and test this approach. The paper also explores the issue of the functional roles of consciousness, in relation to the proposed mechanistic explanation of consciousness. The model, embodying the representational difference, is able to account for the (...) functional role of consciousness, in the form of the synergy between the conscious and the unconscious. The fit between the model and various cognitive phenomena and data (documented in the psychological literatures) is discussed to accentuate the plausibility of the model and its explanation of consciousness. Comparisons with existing models of consciousness are made in the end. (shrink)

Recent work shows an important asymmetry in lay intuitions about moral dilemmas. Most people think it is permissible to divert a train so that it will kill one innocent person instead of five, but most people think that it is not permissible to push a stranger in front of a train to save five innocents. We argue that recent emotion-based explanations of this asymmetry have neglected the contribution that rules make to reasoning about moral dilemmas. In two experiments, we find (...) that participants show a parallel asymmetry about versions of the dilemmas that have minimized emotional force. In a third experiment, we find that people distinguish between whether an action violates a moral rule and whether it is, all things considered, wrong. We propose that judgments of whether an action is wrong, all things considered, implicates a complex set of psychological processes, including representations of rules, emotional responses, and assessments of costs and benefits.

Furthermore, in a few years the types of these genetically engineered "vegetables" are sure to increase and may very possibly also include human genes.

The issue of methodological solipsism in the philosophy of mind and psychology has received enormous attention and discussion in the decade since the appearance Jerry Fodor's "Methodological Solipsism" [Fodor 1980]. But most of this discussion has focused on the consideration of the now infamous "Twin Earth" type examples and the problems they present for Fodor's notion of "narrow content". I think there is deeper and more general moral to be found in this issue, particularly in light of Fodor's more recent (...) defense of his view in Psychosemantics [Fodor 1987]. Underlying this discussion are questions about the nature and plausibility of the claim that scientific explanation should observe a constraint of methodological individualism . My goal in what follows is to bring out this more general problem in Fodor's "internalist" account of the mental. (shrink)

This paper describes how meta-cognitive processes (i.e., the self monitoring and regulating of cognitive processes) may be captured within a cognitive architecture Clarion. Some currently popular cognitive architectures lack sufficiently complex built-in meta-cognitive mechanisms. However, a sufficiently complex meta-cognitive mechanism is important, in that it is an essential part of cognition and without it, human cognition may not function properly. We contend that such a meta-cognitive mechanism should be an integral part of a cognitive architecture. Thus such a mechanism has (...) been developed within the Clarion cognitive architecture. The paper demonstrates how human data of two meta-cognitive experiments are simulated using Clarion. The simulations show that the meta-cognitive processes represented by the experimental data (and beyond) can be adequately captured within the Clarion framework. (shrink)

It is argued that the prevailing definition of quasicrystals, requiring them to contain an axis of symmetry that is forbidden in periodic crystals, is inadequate. This definition is too restrictive in that it excludes an important and interesting collection of structures that exhibit all the well-known properties of quasicrystals without possessing any forbidden symmetries.

In a series of papers Geoff Moore has applied Alasdair MacIntyre’s much cited work to generate a virtue-based business ethics. Central to this project is Moore’s argument that business falls under MacIntyre’s concept of ‘practice’. This move attempts to overcome MacIntyre’s reputation for being ‘anti-business’ while maintaining his framework for evaluating social action and replaces MacIntyre’s hostility to management with a conception of managers as institutional practitioners (craftsmen). I argue however that this move has not been justified. Given the importance (...) MacIntyre places on the protection of practices, the result is that much of Moore’s contribution is misplaced. Business cannot name a practice but business institutions certainly do house practices. The task then is to try to understand the circumstances under which practices might flourish and those under which they might founder in a business context. This is not aided by Moore’s redescription of all businesses as practices. (shrink)

This paper discusses essential motivational representations necessary for a comprehensive computational cognitive architecture. It hypothesizes the need for implicit drive representations, as well as explicit goal representations. Drive representations consist of primary drives — both low-level primary drives (concerned mostly with basic physiological needs) and high-level primary drives (concerned more with social needs), as well as derived (secondary) drives. On the basis of drives, explicit goals may be generated on the fly during an agent’s interaction with various situations. These motivational (...) representations help to make cognitive architectural models more comprehensive and provide deeper explanations of psychological processes. This work represents a step forward in making computational cognitive architectures better reflections of the human mind and all its motivational complexity and intricacy. (shrink)

Symbols should be grounded, as has been argued before. But we insist that they should be grounded not only in subsymbolic activities, but also in the interaction between the agent and the world. The point is that concepts are not formed in isolation (from the world), in abstraction, or "objectively." They are formed in relation to the experience of agents, through their perceptual/motor apparatuses, in their world and linked to their goals and actions. This paper takes a detailed look at (...) this relatively old issue, with a new perspective, aided by our work of computational cognitive model development. To further our understanding, we also go back in time to link up with earlier philosophical theories related to this issue. The result is an account that extends from computational mechanisms to philosophical abstractions. (shrink)

Leda Cosmides and John Tooby have some advice for moral philosophers and deontic logicians trying to understand deontic notions like ought: give up trying to provide a univocal, domain-general treatment. The domain-specific character of human cognition means that such a research program is probably fruitless and probably pointless. It is probably fruitless, since a univocal account of the meaning of "ought" will not capture the multiple inferential patterns of deontic reasoning exhibited in different contexts (and similarly for lots of other (...) words like "obligation," "entitlement," etc. - but let’s stick with "ought"). And it is probably pointless, because even if a domain general logic can be developed, it will "fail to capture major distinctions the human mind makes when reasoning deontically" (ms 5). As a result, it is "not likely to be widely understood and adopted" so it will "not succeed in guiding ethical decisions beyond an esoteric circle of specialists" (ms 5). (shrink)

The following story is about the Venerable Mahā-maudgalyāyana,[2] an enlightened disciple of the historical Buddha Śākyamuni. Mahā-maudgalyāyana travels to a distant solar system, to a planet which is inhabited by giant people, and on which there is also a Buddha with disciples practicing under his guidance. The story, which brings to mind Swift’s Gulliver in the land of the giants, is remarkable in many respects. The Buddha and Mahā- maudgalyāyana both probably lived during the fifth and sixth centuries BCE. In (...) the European West, until the time of Galileo (1564-1642), most educated people thought the whole cosmos rotated around the earth and consisted of the sun and seven planets. They did not realize that the stars were other suns. This story here related shows that 2,500 years ago, Buddhists were aware of a vast cosmos filled with suns and planets and sentient life. Contemporary, scientifically oriented people often have a tendency to dismiss non-Western cosmologies as limited, primitive, and distorted myths, in the negative sense of that word. In this story we are presented with a cosmology that seems much closer than the Western pre-Galilean view to the contemporary scientific view of the physical universe. Of course the assertions about the spiritual powers of the Buddha and Mahā-maudgalyāyana and the size of the people on the distant planet do not merge so easily with contemporary scientific, materialist mindsets.

Most of the work in agent-based social simulation has assumed highly simplified agent models, with little attention being paid to the details of individual cognition. Here, in an effort to counteract that trend, we substitute a realistic cognitive agent model (CLARION) for the simpler models previously used in an organizational design task. On that basis, an exploration is made of the interaction between the cognitive parameters that govern individual agents, the placement of agents in different organizational structures, and the performance (...) of the organization. It is suggested that the two disciplines, cognitive modeling and social simulation, which have so far been pursued in relative isolation from each other, can be profitably integrated. (shrink)

This exploratory study examines how managers and professionals regard the ethical and social responsibility reputations of 60 well-known Australian and International companies, and how this in turn influences their attitudes and behaviour towards these organisations. More than 350 MBA, other postgraduate business students, and participants in Australian Institute of Management management education programmes were surveyed to evaluate how ethical and socially responsible they believed the 60 organisations to be. The survey sought to determine what these participants considered 'ethical' and 'socially (...) responsible' behaviour in organisations to be. The survey also examined how the participants' beliefs influenced their attitudes and intended behaviours towards these organisations. The results of this survey indicate that many managers and professionals have clear views about the ethical and social responsibility reputations of companies. This affects their attitudes towards these organisations which in turn has an impact on their intended behaviour towards them. These findings support the view in other research studies that well-educated managers and professionals are, to some extent, taking into account the ethical and social responsibility reputations of companies when deciding whether to work for them, use their services or buy shares in their companies.
