In the debate between simple inference heuristics and complex decision mechanisms, we take a position squarely in the middle. A decision making process that extends to both naturalistic and novel settings should extend beyond the confines of this debate; both simple heuristics and complex mechanisms are cognitive skills adapted to and appropriate for some circumstances but not for others. Rather than ask `Which skill is better?'' it is often more important to ask `When is a skill justified?'' The selection and (...) application of an appropriate cognitive skill for a particular problem has both costs and benefits, and therefore requires the resolution of a tradeoff. In revisiting satisficing, we observe that the essence of satisficing is tradeoff. Unlike heuristics, which derive their justification from empirical phenomena, and unlike optimal solutions, which derive their justification by an evaluation of alternatives, satisficing decision-making derives its justification by an evaluation of consequences. We formulate and present a satisficing decision paradigm that has its motivation in Herbert Simon''s work on bounded rationality. We characterize satisficing using a cost–benefit tradeoff, and generate a decision rule applicable to both designing intelligent machines as well as describing human behavior. (shrink)

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)

The third volume of Ordo V in the Amsterdam edition of the Latin texts of Erasmus presents the second half of Erasmus’ commentaries on eleven Psalms. Two of them not only explain the psalms themselves, but also deal with topical questions, viz. the war against the Turks and the disintegration of Christendom.

Background:The severity of the Coronavirus pandemic has led to lockdowns in different countries to reduce the spread of the infection. These lockdown restrictions are likely to be detrimental to mental health and well-being in adolescents. Physical activity can be beneficial for mental health and well-being; however, research has yet to examine associations between adolescent physical activity and mental health and well-being during lockdown.Purpose:Examine the effects of adolescent perceived Coronavirus prevalence and fear on mental health and well-being and investigate the extent (...) to which physical activity can be a protective factor against these concerns.Methods:During United Kingdom lockdown restrictions, 165 participants (100 female, aged 13–19) completed an online questionnaire assessing perceived Coronavirus prevalence and fear, physical activity, and indicators of mental health and well-being (stress, anxiety, depression, fatigue, vitality, and perceived health). Separate hierarchical multiple linear regression analyses (with age, gender, perceived Coronavirus prevalence, and fear entered in step 1, and physical activity in step 2) were run to predict each well-being outcome.Results:Regression analyses indicated that in general, while Coronavirus fear was a negative predictor, physical activity was a positive and stronger predictor of enhanced mental health and well-being outcomes.Conclusion:Findings suggest that physical activity during the Coronavirus pandemic can counteract the negative effects of Coronavirus fear on adolescent mental health and well-being. Therefore, physical activity should be promoted during lockdown to support good mental health and well-being. (shrink)

In spite of successful tests, the standard cosmological model, the $$\varLambda$$ CDM model, possesses the most problematic concept: the initial singularity, also known as the big bang. In this paper—by adopting the Kantian difference between to think of an object and to cognize an object—it is proposed a degree of scientificity using fuzzy sets. Thus, the notion of initial singularity will not be conceived of as a scientific issue because it does not belong to the fuzzy set of what is (...) known. Indeed, the problematic concept of singularity is some sort of what Kant called the noumenon, but science, on the other hand, is constructed in the phenomenon. By applying the fuzzy degree of scientificity in cosmological models, one concludes that cosmologies with a contraction phase before the current expansion phase are potentially more scientific than the standard model. At the end of this article, it is shown that Kant’s first antinomy of pure reason indicates a limit to our cosmological models. (shrink)

Background: We aimed to determine the smallest changes in health-related quality of life (HRQoL) scores in the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire core 30 and the Brain Cancer Module (QLQ-BN20), which could be considered as clinically meaningful in brain cancer patients. Materials and methods: World Health Organisation performance status (PS) and mini-mental state examination (MMSE) were used as clinical anchors appropriate to related subscales to determine the minimal clinically important differences (MCIDs) in HRQoL (...) change scores (range 0-100) in the QLQ-C30 and QLQ-BN20. A threshold of 0.2 standard deviation (SD) (small effect) was used to exclude anchor-based MCID estimates considered too small to inform interpretation. Results: Based on PS, our findings support the following integer estimates of the MCID for improvement and deterioration, respectively: physical (6, 9), role (14, 12), and cognitive functioning (8, 8); global health status (7, 4(star)), fatigue (12, 9), and motor dysfunction (4(star), 5). Anchoring with MMSE, cognitive functioning MCID estimates for improvement and deterioration were (11, 2(star)) and for communication deficit were (9, 7). Estimates with asterisks were <0.2 SD and were excluded from our MCID range of 5-14. Conclusion: These estimates can help clinicians evaluate changes in HRQoL over time, assess the value of a health care intervention and can be useful in determining sample sizes in designing future clinical trials.

Under what circumstances if ever ought we to grant that Artificial Intelligences (AI) are persons? The question of whether AI could have the high degree of moral status that is attributed to human persons has received little attention. What little work there is employs western conceptions of personhood, while non-western approaches are neglected. In this article, I discuss African conceptions of personhood and their implications for the possibility of AI persons. I focus on an African account of personhood that is (...) prima facie inimical to the idea that AI could ever be ‘persons’ in the sense typically attributed to humans. I argue that despite its apparent anthropocentrism, this African account could admit AI as persons. (shrink)

In recent work Timothy Williamson argues that the epistemology of metaphysical modality is a special case of the epistemology of counterfactuals. I argue that Williamson has not provided an adequate argument for this controversial claim, and that it is not obvious how what he says should be supplemented in order to derive such an argument. But I suggest that an important moral of his discussion survives this point. The moral is that experience could play an epistemic role which is more (...) epistemically significant than a mere 'enabling' role but not equivalent to an evidential role. (shrink)

We discuss explanation of an earlier event by a later event, and argue that prima facie cases of backwards event explanation are ubiquitous. Some examples: (1) I am tidying my flat because my brother is coming to visit tomorrow. (2) The scarlet pimpernels are closing because it is about to rain. (3) The volcano is smoking because it is going to erupt soon. We then look at various ways people might attempt to explain away these prima facie cases by arguing (...) that in each case the 'real' explanation is something else. We argue that none of the explaining-away strategies are successful, and so any plausible account of explanation should either make room for backwards explanation, or have a good story to tell about why it doesn't have to.

The goal of the research programme I describe in this article is a realist epistemology for arithmetic which respects arithmetic's special epistemic status (the status usually described as a prioricity) yet accommodates naturalistic concerns by remaining fundamentally empiricist. I argue that the central claims which would allow us to develop such an epistemology are (i) that arithmetical truths are known through an examination of our arithmetical concepts; (ii) that (at least our basic) arithmetical concepts are accurate mental representations of elements (...) of the arithmetical structure of the independent world; (iii) that (ii) obtains in virtue of the normal functioning of our sensory apparatus. The first of these claims protects arithmetic's special epistemic status relative, for example, to the laws of physics, the second preserves the independence of arithmetical truth, and the third ensures that we remain empiricists.

This paper takes the form of a critical discussion of Crispin Wright’s notion of entitlement of cognitive project. I examine various strategies for defending the claim that entitlement can make acceptance of a proposition epistemically rational, including one which appeals to epistemic consequentialism. Ultimately, I argue, none of these strategies is successful, but the attempt to isolate points of disagreement with Wright issues in some positive proposals as to how an epistemic consequentialist should characterize epistemic rationality.

Lewis has argued that quasi-realism is fictionalism. Blackburn denies this, offering reasons which rely on a descriptive reading of quasi-realism. This note offers a different, more general argument against Lewis's claim, available to prescriptive as well as descriptive quasi-realists.

C. S. Lewis' article addresses a critically important issue on which Howard Ahmanson comments. Professor Oliver O'Donovan addresses the same issue in a sermon in Christ Church Oxford on Trinity Sunday 1997. We publish the three articles together in the year of the fiftieth anniversary of the independence of India and Pakistan and invite correspondence on the issues at stake. Eds.

On the occasion of the 50th anniversary of C. S. Lewis’s death, a special annotated edition of his Christian classic, The Screwtape Letters, with notes and excerpts from his other works that help illuminate this diabolical masterpiece. Since its publication in 1942, The Screwtape Letters has sold millions of copies worldwide and is recognized as a milestone in the history of popular theology. A masterpiece of satire, it offers a sly and ironic portrayal of human life and foibles from the (...) vantage point of Screwtape, a highly placed assistant to “Our Father Below.” At once wildly comic, deadly serious, and strikingly original, The Screwtape Letters comprises the correspondence of the worldly-wise devil Screwtape and his nephew Wormwood, a novice demon in charge of securing the damnation of an ordinary young man. For the first time, The Screwtape Letters will be presented in full-text accompanied by helpful annotations in a striking two-color format. These annotations will give fans a deeper, more nuanced understanding of the popular book, providing background information, explanations of terms, historical significance, and excerpts from Lewis’s other works that more fully explain the ideas in this volume. For both expert Lewis fans and casual readers, The Screwtape Letters: Annotated Edition will be a beautiful and insightful guide to a beloved classic. (shrink)

This chapter attempts to put structure on some of the different philosophical uses of ‘intuition’. It argues that ‘intuition’-hood is associated with four bundles of symptoms: a commonsensicality bundle; an a prioricity and immediacy bundle, and a metaphilosophical bundle. Tentatively suggesting that the word ‘intuition’ as used by philosophers is best regarded as ambiguous, the chapter offers a much simpler view concerning the meaning of ‘intuition’ in philosophy. With some of the attacks on ‘intuition’ as an epistemic source explored, the (...) chapter concludes that one significant kind of philosophical ‘intuition’, related to a prioricity and conceptual truth, can be defended against a range of typical epistemological challenges.
