本文旨在初步探索「限肉令」作為應對傳染病大流行和由工廠化畜牧業帶來的其他威脅的預防措施的正當性。「限肉令」並非指全面禁肉，而是以法律限制市民的人均肉品消耗量在滿足基本營養需求的範圍內。本文採用的進路是 緩解一些可能阻礙對此提案進行更宏觀、理性的思考的潛在心理拘繫。此進路參考了傅柯「日常經驗」(everyday experience) 的分析，和佛家倫理學回應全球環境倫理問題的策略。我們先以香港社會為主要案例研究，檢視形成「肉是必需的」一想法和嗜肉情結的社會模式。接著我們引入葷食心理學研究，討論嗜肉情結如何成為正面考慮「限肉令」的障 礙。我們也嘗試回應一些反對此提案的理由，包括來自自由主義 (Liberalism)的批評。 -/- This article explores the preliminary justifiability of meat restriction order as a preventive measure to the risks of pandemic and other forms of harm posed by factory farming. A meat restriction order seeks to limit citizens’ meat consumption at the level of meeting individuals’ basic nutrient needs. This article aims to loosen some potential psychological hooks that prevent a more expansive, rational deliberation of the proposal. Inspired by Michel Foucault’s analysis of “everyday experience” and the (...) Buddhist responses to global environmental issues, we investigate the social patterns that account for the formation of people’s meat commitment, using Hong Kong society as a major case study. With reference to scientific studies of meat-eaters’ psychology, we discuss how the meat commitment becomes a barrier for society to positively consider the justifiability of the proposal. We will also address a number of objections to our proposal, including those from liberalism. (shrink)

Welcome to the world of cutting-edge math, physics, and neuroscience, where the search for the ultimate vacuum, the point of nothingness, ground zero of theory, has rendered the universe deep, rich, and juicy. "Modern physics has animated the void," says K. C. Cole in her entrancing journey into the heart of Nothing. Every time scientists and mathematicians think they have reached the ultimate void, new stuff appears: a black hole, an undulating string, an additional dimension of space or time, repulsive (...) anti-gravity, universes that breed like bunnies. Cole's exploration at the edge of everything is as animated and exciting as the void itself. Take Cole's hand on this adventure into the unknown, and you'll come back informed, amused, and excited.

Quality of life is a difficult concept to define and to measure. An hypothesis is proposed which suggests that the quality of life measures the difference, or the gap, at a particular period of time between the hopes and expectations of the individual and that individual's present experiences. Quality of life can only be described by the individual, and must take into account many aspects of life. The approach is goal-orientated, and one of task analysis. The hypothesis is developed in (...) a diagramatic way, and several methods of testing the hypothesis suggested. (shrink)

I Propose to re-explore here some aspects of a very shop-worn question: ‘Was Hobbes in any sense an atheist?’ Three centuries ago, Hobbes's personal security in part depended on the way his contemporaries answered this question; today, the validity of several current accounts of his philosophy are similarly bound up with it. These accounts vary extraordinarily, all the way from Polin's confident assertion that ‘ pour qui sait lire entre les lignes, … c'est ľatheísme qui triomphe implicitement ’, to Taylor's (...) equally firm belief that ‘a certain kind of theism is necessary to make [Hobbes's] theory work.’ 1 And now the latest of the Taylorians, Prof. Howard Warrender, has published his book The Political Philosophy of Hobbes , in which Hobbes's statements regarding the place of God are again treated as an essential part of his theory; and the charge explicitly made, that there are no sound grounds for regarding them as ‘the product of confusion or pretence on Hobbes's part’.

Professor C. A. Mace, the psychologist, once wrote: ‘It is difficult … to present and defend any sort of behaviourism whatever without committing oneself to nonsense.’ I shall illustrate this thesis. I shall comment on the writings of some psychologists. This is relevant to my topic; for psychologists' expositions of behaviourism contain much more philosophy than science, and the inconsistencies which permeate their versions of behaviourism reappear in the works of eminent philosophers. My quotation from Mace comes from a paper (...) defending what he calls ‘analytical behaviourism’; which he distinguishes from ‘methodological behaviourism’ and ‘metaphysical behaviourism’. According to Mace, analytical behaviourism does not question the truth of our everyday statements about a person's mind or states of consciousness; what it claims is that such statements ‘turn out to be, on analysis, statements about the behaviour of material things’, that is, about a person's ‘bodily acts, bodily states, bodily dispositions, bodily “states of readiness” to act in various ways’. The father of behaviourism, J. B. Watson, rarely says anything suggesting this doctrine. As he presents it, behaviourism is both a methodological principle and a metaphysical theory. (shrink)

This paper stems from an ethnographic, multidisciplinary study that explored the views and experiences of practitioners and scientists on social, ethical and clinical dilemmas encountered when working in the area of pre-implantation genetic diagnosis for serious genetic disorders. We focus here on staff perceptions and experiences of working with embryos and helping women/couples to make choices that will result in selecting embryos for transfer and disposal of 'affected' embryos, compared to the termination of affected pregnancies following prenatal diagnosis. Analysis and (...) discussion of our data led us to consider the possible advantages of pre-implantation genetic diagnosis and whether a gradualist account of the embryo's and fetus's moral status can account for all of these, particularly since a gradualist account concentrates on the significance of time (developmental stage) and makes no comment as to the significance of place (in vitro, in utero).

– The paper explores first the postulational basis and significance of‘measures of information’in current information theory and their possible relations to physical entropy and Brillouin's‘negentropy’regarded as the negative of entropy. For some purposes, the same pattern or formal structure may be abstracted from both‘entropy’and‘information’. The paper analyzes, in the second place, the mathematical analogies which have been traced between information theory and quantum mechanics and argues that the analogies have but a limited value when we come to grips with the (...) deeper, and yet unsolved, problems of quantum theory. Lastly it is urged that the indiscriminate extensions of statistical and information‐theoretic methods, and of quantum‐mechanical analogies, e.g.‘linguistic duality’, to psycholinguistics, literary and aesthetic Gestalten, can result only in crude exaggerations. Dialectical methodology requires the continual reformulation of all scientific descriptions which have to reckon perpetually with the richness of human materials. (shrink)

This book would be very important indeed if Mr. Spencer Brown had substantiated his claims “that the concept of probability used in statistical science is meaningless in its own terms” , and that confirming this is the only significance of experiments in psychical research. The six short introductory chapters need not be discussed here. It is in Chapters VII to IX that the author develops his thesis that the concept of randomness is self–contradictory, and the statistician's concept of probability consequently (...) meaningless. I shall examine what I take to be the central argument leading to this conclusion. This is developed from a distinction between “primary chance or randomness” and “secondary chance or randomness” . The former concept is to be applicable only to individual events and is to depend upon their “unexpectedness or unpredictability”; the latter concept, applicable only to a series as such, is denned as “possessing no discernible pattern” . The definition of “primary randomness” is amplified, but not clarified, on page 49: “An event is primarily random in so far as... one cannot be sure of its occurrence... The only relevant criterion is that we are able to guess ”. We are then told that primary randomness “admits of analysis in subjective terms”, since the same event may be predictable by one person but unpredictable by another; whereas secondary randomness is “a more objective concept”.

Open peer commentary on the article “The Banathy Conversation Methodology” by Gordon Dyer, Jed Jones, Gordon Rowland & Silvia Zweifel. Upshot: Banathy’s Conversation Methodology and the conversation events where it was developed and practiced had a profound effect on my role as a scholar-practitioner. In this commentary, I reflect on the impact of the BCM in my professional practice as an educator, facilitator, and consultant within the field of social innovation, where participatory processes for eliciting the wisdom of the group (...) are essential.

Upshot: The commentaries raise a plethora of issues, extending the article’s problematic in insightful ways. In this response, we chose to focus on two interesting views on the “powerful idea” in the constructionist sense, on systems versus causal-rule thinking and on the affective aspect of collaborative learning.

Open peer commentary on the article “Examining the Role of Re-Presentation in Mathematical Problem Solving: An Application of Ernst von Glasersfeld’s Conceptual Analysis” by Victor V. Cifarelli & Volkan Sevim. Upshot: Education researchers often explain student activity in terms of general thinking and learning processes, including those identified by Cifarelli and Sevim. In this commentary, I refocus Cifarelli and Sevim’s discussion in order to hypothesize the organization of mental actions that comprise and support those learning processes.

Our study analyses the nature, quality and extent of human resource disclosures of UK Financial Times Stock Exchange 100 firms by relying on a novel disclosure index measuring the depth and breadth of disclosures. Contextually, we focus on the 5-year period following the then Labour government’s attempts to encourage firms to formally report on their human resource management practices and to foster deeper employer–employee engagement. First, we evaluate the degree to which companies report comprehensively on a number of HRD items (...) that we classify as “procedural” or “sustainable.” Second, we hypothesise that a company’s employee relation ideology is positively associated with HRD. Our results indicate that: whilst there has been an increase in the breadth of HRD in terms of procedural and sustainable items being disclosed, the evolution towards a more comprehensive and in-depth form of HRD remains rather limited; and there is a positive association between a company’s employee relation ideology and the level of HRD. Theoretically, we conceive of HRD both as a reflection of an organisation’s orientation towards a key stakeholder and a legitimacy seeking exercise at a time of changing societal conditions. We contribute to the scant literature on the extent and determinants of HRD since prior research tends to subsume employee-related disclosures within the broader concept of social, ethical or intellectual capital disclosures. We also propose a disclosure checklist to underpin future HRD research. (shrink)

"Professor Mundle's authoritative and acclaimed critique of a way of thinking which still shapes the style of Anglo-Saxon philosophy is here presented in a revised text with a new postscript. Mundle shows how Austin, Ryle and Wittgenstein, among others, not only committed grammatical and logical errors akin to those they themselves detected in others, but misunderstood the relatoins between grammar and philosphy. Professor P.L. Heath contributes a new foreword, and Mundle himself answers his opponents in a subtly provocative manner." --.

The third volume of Professor Guthrie's great history of Greek thought, entitled The Fifth-Century Enlightenment, deals in two parts with the Sophists and Socrates, the key figures in the dramatic and fundamental shift of philosophical interest from the physical universe to man. Each of these parts is now available as a paperback with the text, bibliography and indexes amended where necessary so that each part is self-contained. The Sophists assesses the contribution of individuals like Protagoras, Gorgias and Hippias to the (...) extraordinary intellectual and moral fermant in fifth-century Athens. They questioned the bases of morality, religion and organized society itself and the nature of knowledge and language; they initiated a whole series of important and continuing debates, and they provoked Socrates and Plato to a major restatement and defence of traditional values.

Despite extensive stigma mitigation efforts, infectious disease stigma remains common. So far, little attention has been paid to the moral psychology of stigmatizing practices (i.e. beliefs, attitudes, actions) rather than the experience of being stigmatized. Addressing the moral psychology behind stigmatizing practices seems necessary to explain the persistence of infectious disease stigma and to develop effective mitigation strategies. Our article proposes building on Jonathan Haidt’s moral foundations theory, which states that moral judgements follow from intuitions rather than conscious reasoning. Conceptual (...) analysis was conducted to show how Haidt’s five moral foundations can be connected to (i) moral judgements about stigmatizing practices and (ii) stigmatizing practices themselves. We found that care/harm, fairness/cheating, loyalty/betrayal and sanctity/degradation intuitions can inform moral judgements about stigmatizing practices. Loyalty/betrayal and sanctity/degradation intuitions can sometimes also feed stigmatizing practices. Authority/subversion intuitions can inform moral judgements and stigmatizing practices towards people who disrespect authoritative rules meant to protect public health. Moral dumbfounding and posthoc reasoning might explain the persistence of stigmatizing practices. In conclusion, this study demonstrates the relevance of Haidt’s approach to infectious disease stigma research and mitigation strategies. We hope that this study motivates researchers to further test and assess this approach. (shrink)

Context: In the literature concerning the theory of social systems, interest in epistemological and ontological questions has increased in recent years. The controversies regarding a realist vs. constructivist interpretation of Luhmann’s theory, as well as the concept of many realities that correspond to many ontologies, deserve attention. Problem: The paper discusses interrelated ontological and epistemological problems in Luhmann’s systems theory, such as ontology and de-ontologization, realism vs. constructivism, contingency and its limits and one vs. many realities. Method: The paper proposes (...) an interpretation, according to which systems theory is based on an epistemology - radical operative constructivism. Results: Luhmann is not a realist. The last word belongs to radical operative constructivism, and naïve realism with reference to social systems has only a preliminary, methodological significance. However, taking a position in the dispute between realism and constructivism inevitably involves an ontological “vocabulary,” that is, usage of the reality/construction distinction. Furthermore, operative constructivism formulates the necessary conditions of the possibility of cognition, which limit the contingency of the theory and constitute one reality that is a construction of systems theory. Luhmann rejects ontology, but he does not renounce epistemology, and consequently the project of de-ontologization remains incomplete. Implications: The paper offers a new, coherent interpretation of ontological and epistemological questions in Luhmann’s theory, and also throws light on some problems of radical constructivism in general, such as the ontological implications of epistemology or the constructivist self-reference of theories. Key words: Radical operative constructivism, social systems, Luhmann, ontology, reality, contingency. (shrink)

According to David Lewis’s Modal Realism, other possible worlds really exist as concrete, spatiotemporal systems, and every way that a world could be is a way that some world is. To establish this plenitude of concrete possible worlds, Lewis presents his ‘principle of recombination,’ which is meant to guarantee that there exists a possible world, or part of a possible world, for every possibility. Jessica Wilson has recently argued that Lewis’s principle of recombination fails to generate enough worlds to account (...) for the plenitude of possibilities. Namely, Wilson argues that the principle of recombination cannot account for the possibility of spatially overlapping but distinct fundamental entities, as well as certain macroscopic entities. In this paper, I will defend Lewis’s principle of recombination against these charges, arguing that Wilson’s objections overlook features of Lewisian metaphysics that can solve the problems at hand.

Are mystical experiences primarily formed by the mystic's cultural background and concepts, as modern day "constructivists" maintain, or do mystics in some way transcend language, belief, and culturally conditioned expectations? Do mystical experiences differ in the different religious traditions, as "pluralists" contend, or are they identical across cultures? Twelve contributors here attempt to answer these questions through close examination of a particular form of mystical experience, "Pure Consciousness"--the experience of being awake but devoid of intentional content for consciousness. The contributors (...) analyze pure consciousness and other mystical experiences from historical Hindu, Buddhist, Christian, and Jewish sources, as well as from modern mystics. They demonstrate that pure consciousness poses serious conceptual problems for a contructivist understanding of mysticism. Revealing the inconsistencies and inadequacies of current models, they make significant strides towards developing new models for the phenomenon of mysticism, breaking new ground for our understanding of mysticism and of human experience in general.

Evolutionary developmental biology (evo-devo) has undergone dramatic transformations since its emergence as a distinct discipline. This paper aims to highlight the scope, power, and future promise of evo-devo to transform and unify diverse aspects of biology. We articulate key questions at the core of eleven biological disciplines—from Evolution, Development, Paleontology, and Neurobiology to Cellular and Molecular Biology, Quantitative Genetics, Human Diseases, Ecology, Agriculture and Science Education, and lastly, Evolutionary Developmental Biology itself—and discuss why evo-devo is uniquely situated to substantially improve (...) our ability to find meaningful answers to these fundamental questions. We posit that the tools, concepts, and ways of thinking developed by evo-devo have profound potential to advance, integrate, and unify biological sciences as well as inform policy decisions and illuminate science education. We look to the next generation of evolutionary developmental biologists to help shape this process as we confront the scientific challenges of the 21st century. (shrink)

Upshot: The commentaries concentrate mostly on ontological issues but overlook the main epistemological argument in my target article. This argument refers to the conditions that make cognition possible, and to the limits of cognition. These are important for two reasons: they have ontological consequences and they limit the theory’s contingency.

The third volume of Professor Guthrie's great history of Greek thought, entitled The Fifth-Century Enlightenment, deals in two parts with the Sophists and Socrates, the key figures in the dramatic and fundamental shift of philosophical interest from the physical universe to man. Each of the two parts is available as a paperback with the text, bibliography and indexes amended where necessary so that each part is self-contained. Socrates dominated the controversies of this period, as he has dominated the subsequent history (...) of western philosophy. He was the first to identify and grapple with some of the most intractable and persistent logical and philosophical problems; but he was also and has remained a highly controversial figure because of his extraordinary personal qualities and his remarkable career. Professor Guthrie offers a balanced and comprehensive picture of the man, his life, and his thought. (shrink)

The aim of this study was to test red - green dichromats' ability to discriminate between illuminant and surface-reflectance changes in natural scenes. Stimuli were simulations of natural scenes presented on a colour monitor with 10-bit resolution per gun. The natural scenes were obtained with a fast hyperspectral imaging system. Six different scenes (including rocks, foliage, and buildings) were tested. In each trial, two images were presented in sequence, each for 1 s, with no interval. The images differed in the (...) phase of daylight on the scene: first with correlated colour temperature 25 000 K, then 6 700 K. The spectral reflectance of a region in the second image was changed randomly, consistent with a local change in daylight. The observer's task was to decide whether a particular surface in the successive images was the same (pure illuminant change) or different (illuminant change with a surface-reflectance change). The performance of four deuteranopes and five protanopes varied considerably across the scenes tested, with mean colour constancy indices (± 1 SEM) of 0.48 (± 0.13) and 0.19 (± 0.10), respectively (1.0 representing ideal performance). Deuteranopes seemed less disadvantaged than protanopes, performing close to normal with some scenes. (shrink)

About G.M.A Grube's translations of Plato: "Unmistakably superior: more lucid, more accurate, more readable.

The purpose of this paper is threefold. First, I visit the Fogelin–Geach-dispute, criticizeMiller''s interpretation of the Geachian notationN(x:N(fx)) and conclude that Fogelin''s argumentagainst the expressive completeness of the Tractariansystem of logic is unacceptable and that the adoptionof the Geachian notation N(x:fx) would not violate TLP5.32. Second, I prove that a system of quantificationtheory with finite domains and with N as the solefundamental operation is expressively complete. Lastly, I argue that the Tractarian system is apredicate-eliminated many-sorted theory (withoutidentity) with finite domains (...) and with N as the solefundamental operation, and thus is expressivelycomplete.

All volumes of Professor Guthrie's great history of Greek philosophy have won their due acclaim. The most striking merits of Guthrie's work are his mastery of a tremendous range of ancient literature and modern scholarship, his fairness and balance of judgement and the lucidity and precision of his English prose. He has achieved clarity and comprehensiveness.

Martin presents fifteen previously unpublished essays which he wrote before 1973. Despite several references to his earlier books such as Truth and Denotation, these essays will be intelligible to those who have not yet read anything by R. M. Martin as long as you can master long formulations in the notation of a formal first-order language. Indeed, these essays can serve as an introduction to the work of Martin. The first three essays present Martin's metaphysical system. Essays 4, 5, and (...) 6 amplify his system by showing how a wide variety of sentences can have their logical form represented in the formal language which displays Martin's ontology. In the remaining nine essays he critically evaluates positions of other philosophers such as Hiz, Carnap, Quine, Fitch, Chisholm, Popper, Sellars, Heyting, Lorenzen, and Putnam, from the perspective of his system. Because his systematic approach unifies all of the papers and because he uses technical terms in the development of his system, it is regrettable that the book offers no index. (shrink)

This anthology consists of forty-nine of Geach’s previously published papers on logic. He opens his Preface by writing: "I bring together here almost all my English articles that I have previously published and have not already collected or cannibalized in other books." It contains his first published paper "Designation and Truth" from Analysis 1947-48 as well as his elegant sketch of a decidable entailment system in the 1970 Philosophical Review. For the most part he has made only stylistic changes and (...) added some notes. So, he claims: "all articles appear without substantial change." However, he admits that he divided his "Quantification Theory and the Problem of Identifying Objects of Reference" from the now classic 1963 volume of Acta Philosophica Fennica. He divided it because he wanted to separate his strong advocacy of a substitution interpretation of the quantifiers from some views on quotation marks, about which he is less than certain. The papers are not in mere chronological order. They are organized by topic within chapters entitled: Historical Essays, Traditional Logic, Theory of Reference and Syntax, Intentionality, Quotation and Semantics, Set Theory, Identity Theory, Assertion, Imperatives and Practical Reasoning, and Logic in Metaphysics and Theology. The chapter titles are a fair guide to content. But note the following. Two lucid papers defending von Wright’s notion of entailment are in the Intentionality chapter. The essay "Ascriptivism" in the Assertion chapter is relevant to discussions of free will because he argues: "to ascribe an act to agent is a causal description of the act" and he urges a search for a non-Humean analysis of causality. The essays in the last chapter are: "Nominalism," "Some problems about time," and "God’s relation to the world.". (shrink)

This ninth volume in the Library of Exact Philosophy series is a development of the author’s 1971 McGill University dissertation written under the guidance of Mario Bunge. The thesis of the book is that the objectivity of mathematics does not require that there be any mathematical objects. The objectivity of mathematics is the widespread agreement among working mathematicians on what is provable, i.e., on what entailments hold between mathematical constructs. Castonguay gives precise definitions of several terms; but, unfortunately, "construct" is (...) not one of them. He has set himself the task of arguing that we can account for community recognition and acceptance of proofs without assuming that working mathematicians have had to inspect some special mathematical objects to verify that things are in the mathematical realm as they are said to be in the proved propositions. He does concede that many mathematicians, for heuristic reasons, may need to speak as if there were a mind-independent mathematical realm. (shrink)
