    Ecological Species, Multispecies, and Oaks.Leigh Van Valen - 1976 - Taxon 25 (2/3):233-239.
    Oaks exemplify problems with the reproductive species concept which motivate a reconsideration of the use and nature of species. Ecology is important in the reconsideration. The species level is usually overemphasized in evolutionary thought; selection acts on phenotypes and any mutualistic units. Standard definitions tend to inhibit free conceptual progress. Multispecies, sets of broadly sympatric species that exchange genes, may occur among animals as well as plants and may conceivably bridge kingdoms. This phenomenon can be adaptively important. There may be (...)

    How ubiquitous is adaptation? A critique of the epiphenomenist program.Leigh Van Valen - 2009 - Biology and Philosophy 24 (2):267-280.
    It is important to distinguish adaptation per se (adaptedness, or being adapted) from the more specific concept of adaptation for some function. Commonly used criteria for adaptation in either sense have limited applicability. There are, however, a number of widely applicable criteria for adaptation per se, such as several kinds of cost, low variation, the maintenance of integration, and the fitness distribution of mutations. Application of these criteria leads to the conclusion that adaptation is overwhelmingly prevalent for features of organisms. (...)

    Revisiting Leigh Van Valen’s “A New Evolutionary Law” (1973).Ricard Solé - 2022 - Biological Theory 17 (2):120-125.
    Leigh Van Valen was an American evolutionary biologist who made major contributions to evolutionary theory. He is particularly remembered for his groundbreaking paper “A New Evolutionary Law” (1973) where he provided evidence from fossil record data that the probability of extinction within any group remains essentially constant through time. In order to explain such an unexpected result, Van Valen formulated a very influential idea that he dubbed the “Red Queen hypothesis.” It states that the constant decay must (...)

    Species, sets, and the derivative nature of philosophy.Leigh M. Valen - 1988 - Biology and Philosophy 3 (1):49-66.
    Concepts and methods originating in one discipline can distort the structure of another when they are applied to the latter. I exemplify this mostly with reference to systematic biology, especially problems which have arisen in relation to the nature of species. Thus the received views of classes, individuals (which term I suggest be replaced by units to avoid misunderstandings), and sets are all inapplicable, but each can be suitably modified. The concept of fuzzy set was developed to deal with species (...)

    This article addresses the fiduciary issues raised by the current practice of plan fiduciaries of not only disclaiming any fiduciary responsibility for brokerage window investments, but also abdicating any role (fiduciary or otherwise) in assessing even the general suitability of those investments for a retirement plan, and concludes that the practice is in plain and notorious violation of what ERISA requires of fiduciaries.

    On the natural law defense and the disvalue of ubiquitous miracles.Leigh C. Vicens - 2016 - International Journal for Philosophy of Religion 80 (1):33-42.
    In this paper I explore Peter van Inwagen’s conception of miracles and the implications of this conception for the viability of his version of the natural law defense. I argue that given his account of miraculous divine action and its parallel to free human action, it is implausible to think that God did not prevent natural evil in our world for the reasons van Inwagen proposes. I conclude by suggesting that on the grounds he provides for “epistemic humility” about modal (...)

    Revisiting the conservativity of fixpoints over intuitionistic arithmetic.Mattias Granberg Olsson & Graham E. Leigh - 2023 - Archive for Mathematical Logic 63 (1):61-87.
    This paper presents a novel proof of the conservativity of the intuitionistic theory of strictly positive fixpoints, $$\widehat{{\textrm{ID}}}{}_{1}^{{\textrm{i}}}{}$$ ID ^ 1 i, over Heyting arithmetic ($${\textrm{HA}}$$ HA ), originally proved in full generality by Arai (Ann Pure Appl Log 162:807–815, 2011. https://doi.org/10.1016/j.apal.2011.03.002). The proof embeds $$\widehat{{\textrm{ID}}}{}_{1}^{{\textrm{i}}}{}$$ ID ^ 1 i into the corresponding theory over Beeson’s logic of partial terms and then uses two consecutive interpretations, a realizability interpretation of this theory into the subtheory generated by almost negative fixpoints, and (...)

    Gélase de Césarée. Un compilateur du cinquième siècle.Peter Van Nuffelen - 2002 - Byzantinische Zeitschrift 95 (2):621-639.
    À partir de la fin du cinquième siècle, on rencontre parfois des références à une histoire ecclésiastique de Gélase, évêque de Césarée (367-avant septembre 400) et neveu de Cyrille de Jérusalem (348-387). On a beaucoup spéculé sur le caractère et l'étendue de cet ouvrage, mais depuis les travaux de F.

    Conceptual Issues in Ecology.Esa Saarinen - 1982 - Springer Verlag.
    In this collection of essays, some of the leading ecologists and philosophers discuss the foundations of ecology and evolutionary biology. While large scale philosophical convictions and attitudes often direct the theorist's line of concrete action in data collection and in theory information, the founda tional convictions typically remain tacit, and are seldom argued for. The present collection aims to remedy this situation. It brings together scholars representing different approaches in a joint effort to explicate and analyse some of the key (...)

    El culto binitario en Apocalipsis 4-5.Valens Agino - 2018 - Salmanticensis 65 (1):81-108.
    La narración de la experiencia visionaria del culto celestial en Ap 4-5 desvela dramá- ticamente el culto celestial. Los seres celestiales tributan el culto al que está sentado en el trono y al Cordero. Ambos, el Sentado y el Cordero, son los únicos dignos destinatarios de este culto. Todas las criaturas los reconocen como seres divinos. El hecho de dar culto a ambos supone una modificación innovadora del monoteísmo judío del segundo templo. Así, en su visión, Juan participó en el (...)

    ‘I will know it when I taste it’: trust, food materialities and social media in Chinese alternative food networks.Leigh Martindale - 2020 - Agriculture and Human Values 38 (2):365-380.
    Trust is often an assumed outcome of participation in Alternative Food Networks (AFNs) as they directly connect producers with consumers. It is based on this potential for trust “between producers and consumers” that AFNs have emerged as a significant field of food studies analysis as it also suggests a capacity for AFNs to foster associated embedded qualities, like ‘morality’, ‘social justice’, ‘ecology’ and ‘equity’. These positive benefits of AFNs, however, cannot be taken for granted as trust is not necessarily an (...)

    Decolonizing Educational Research: From Ownership to Answerability.Leigh Patel - 2015 - Routledge.
    _Decolonizing Educational Research_ examines the ways through which coloniality manifests in contexts of knowledge and meaning making, specifically within educational research and formal schooling. Purposefully situated beyond popular deconstructionist theory and anthropocentric perspectives, the book investigates the longstanding traditions of oppression, racism, and white supremacy that are systemically reseated and reinforced by learning and social interaction. Through these meaningful explorations into the unfixed and often interrupted narratives of culture, history, place, and identity, a bold, timely, and hopeful vision emerges to (...)

    The lost history of cosmopolitanism: the early modern origins of the intellectual ideal.Leigh Penman - 2020 - New York, NY: Bloomsbury Academic.
    This book provides the first intellectual history of cosmopolitan ideas in the early modern age. The roots of modern cosmopolitanism can be traced back to as early as the 1500s when a meta-narrative and awareness of the cosmopolitan idea came into existence. Unearthing occurrences of cosmopolitan language in popular media and analysing the writings of leading thinkers, Leigh T.I. Penman illustrates how cosmopolitanism was not, as previously thought, purely secular and inclusive but could be sacred and exclusive too. And, (...)

    Kuchisake-Onna: the horror of motherhood and gender embodiment.Leigh A. Wynn - 2023 - Journal for Cultural Research 27 (3):286-298.
    Am I pretty? A simple question that epitomises both beauty and vulgarity in its monstrous representation of feminine embodiment. In this work, I look at the 2007 Japanese Horror film Carved: The Slit Mouth Woman directed by Koji Shiraishi and its relation to the way in which it the monster Kuchisake-Onna presents the idealised role of motherhood in Japan today. Through this critical examination of the film, we see how communities establish social order and gender scripts of the feminine within (...)

    Theological Determinism Theological determinism is the view that God determines every event that occurs in the history of the world. While there is much debate about which prominent historical figures were theological determinists, St. Augustine, Thomas Aquinas, John Calvin, and Gottfried Leibniz all seemed to espouse the view at least at certain points in their … Continue reading Theological Determinism →.

    Even though disquotationalism is not correct as it is usually formulated, a deep insight lies behind it. Specifically, it can be argued that, modulo implicit commitment to reflection principles, all there is to the notion of truth is given by a simple, natural collection of truth-biconditionals.

    Promoting F.A.I.T.H. in Peer Review: Five Core Attributes of Effective Peer Review.Turner Leigh - 2003 - Journal of Academic Ethics 1 (2):181-188.
    Peer review is an important component of scholarly research. Long a “black box” whose practical mechanisms were unknown to researchers and readers, peer review is increasingly facing demands for accountability and improvement. Numerous studies address empirical aspects of the peer review process. Much less consideration is typically given to normative dimensions of peer review. This paper considers what authors, editors, reviewers, and readers ought to expect from the peer review process. Integrity in the review process is vital if various parties (...)

    Critical Realist versus Mainstream Interdisciplinarity.Leigh Price - 2014 - Journal of Critical Realism 13 (1):52-76.
    In this paper I argue for the superiority of a critical realist understanding of interdisciplinarity over a mainstream understanding of it. I begin by exploring the reasons for the failure of mainstream researchers to achieve interdisciplinarity. My main argument is that mainstream interdisciplinary researchers tend to hypostatize facts, fetishize constant conjunctions of events and apply to open systems an epistemology designed for closed systems. I also explain how mainstream interdisciplinarity supports oppression and gross inequality. I argue that mainstream interdisciplinarity is (...)

    Cyclic proofs for the first-order µ-calculus.Bahareh Afshari, Sebastian Enqvist & Graham E. Leigh - forthcoming - Logic Journal of the IGPL.
    We introduce a path-based cyclic proof system for first-order $\mu $-calculus, the extension of first-order logic by second-order quantifiers for least and greatest fixed points of definable monotone functions. We prove soundness of the system and demonstrate it to be as expressive as the known trace-based cyclic systems of Dam and Sprenger. Furthermore, we establish cut-free completeness of our system for the fragment corresponding to the modal $\mu $-calculus.

    This volume unites established authors and rising young voices in philosophical theology and philosophy of religion to offer the single most wide-ranging examination of theological determinism-in terms of both authors represented and issues investigated-published to date. Fifteen contributors present discussions about theological determinism, the view that God determines everything that occurs in the world. Some authors provide arguments in favor of this position, while others provide considerations against it. Many contributors investigate the relationship between theological determinism and other philosophical issues, (...)

    God and Human Freedom.Leigh C. Vicens & Simon Kittle - 2019 - Cambridge University Press.
    This Element considers the relationship between the traditional view of God as all-powerful, all-knowing and wholly good on the one hand, and the idea of human free will on the other. It focuses on the potential threats to human free will arising from two divine attributes: God's exhaustive foreknowledge and God's providential control of creation.

    Platonic Dialogue, Maieutic Method and Critical Thinking.Fiona Leigh - 2007 - Journal of Philosophy of Education 41 (3):309-323.
    In this paper I offer a reading of one of Plato’s later works, the Sophist, that reveals it to be informed by principles comparable on the face of it with those that have emerged recently in the field of critical thinking. As a development of the famous Socratic method of his teacher, I argue, Plato deployed his own pedagogical method, a ‘mid-wifely’ or ‘maieutic’ method, in the Sophist. In contrast to the Socratic method, the sole aim of this method is (...)

    Economies are complicated systems encompassing micro behaviors, interaction patterns, and global regularities. Whether partial or general in scope, studies of economic systems must consider how to handle difficult real-world aspects such as asymmetric information, imperfect competition, strategic interaction, collective learning, and the possibility of multiple equilibria. Recent advances in analytical and computational tools are permitting new approaches to the quantitative study of these aspects. One such approach is Agent-based Computational Economics (ACE), the computational study of economic processes modeled as dynamic (...)
