Mastery, Dependence, and the Ethics of Authority
by Aaron StalnakerOver the last few decades, skepticism about political and moral experts has grown into a serious social problem, undermining the functioning of liberal democratic regimes. Indeed, meritocracy-that is, government by hard working, public-spirited people with high levels of relevant expertise-has never looked so promising as an alternative to the dangers of know-nothing populism. One cultural tradition has devoted sustained attention to the idea of meritocracy, as well as to the cultivation of true expertise or mastery: Confucianism. Mastery, Dependence, and the Ethics of Authority presents a compelling analysis of expertise and authority, and examines classical Confucian conceptions of mastery, dependence, and human relationships in order to suggest new approaches to these issues in ethics and political theory. Contemporary Westerners are heirs to multiple traditions that are suspicious of authority, especially coercive political authority. We are also increasingly wary of dependence, which now often seems to signify weakness, neediness, and pathology. Analysts commonly presume that both authority and dependence threaten human autonomy, and are thus intrinsically problematic. But these judgments are mistaken. Our capacity for autonomy needs to be cultivated over time through deliberate practices of training, in which we depend on the guidance of virtuous and skilled teachers. Confucian thought provides a subtle and powerful analysis of one version of this training process, and of the social supports such an education in autonomy requires-as well as the social value of having virtuous and skilled leaders. Early Confucians also argue that human life is marked by numerous interacting forms of dependence, which are not only ineradicable, but in many ways good. On a Confucian view, it is natural, healthy, and good for people to be deeply dependent on others in a variety of ways across the full human lifespan. They teach us that individual autonomy only develops within a social matrix, structured by relationships of mutual dependence that can either help or hinder it, including a variety of authority relations.
Matematica e Arte: Forme del pensiero artistico (Convergenze)
by Laura Catastini Franco GhioneIl libro vuole saldare didattica e divulgazione su un tema di grande fascino come quello dei rapporti tra la matematica e l'espressione artistica cercando di andare oltre alle ovvietà che spesso circondano questo argomento, alle facili metafore, a esoterici misteri, con l'obiettivo di fornire un quadro concettuale matematico per quanto possibile rigoroso, accessibile a una cultura liceale, isolando quei temi per i quali non sia pretestuoso l'intreccio tra matematica e arte. Il Cd che accompagna il testo raccoglie il materiale didattico prodotto nella attività laboratoriale con gli studenti: schede di lavoro, animazioni, film, pagine di geometria dinamica, e può essere utilmente utilizzato da chi intenda riproporre nel proprio contesto didattico questa esperienza.
Matematica e cultura 2008 (Matematica e cultura)
by Michele EmmerMatematica e cultura, binomio sorprendente? Potrebbe sembrare ma da qualche anno si sono aperti dei grandi ponti tra le “due culture”. A Venezia, citta’ di ponti e di culture, si parla da oramai dieci anni di cultura e di matematica, si parla di arte, architettura, cinema, letteratura, ambiente, filosofia, di bolle di sapone, di Corto Maltese ed Hugo Pratt, delle investigazioni criminali. In questo nuovo libro, il decimo della serie iniziata a Venezia con gli incontri “Matematica e cultura” che tanti hanno cercato di imitare, si parla di tutto questo e tra gli altri ne scrivono Simon Singh (autore del best seller “L’ultimo teorema di Fermat”), alla sua terza presenza a Venezia, e Siobhan Roberts (autrice di “Il re dello spazio infinito. Storia dell’uomo che salvò la geometria”). Venezia ponte tra la matematica e la cultura.
Matematica e cultura 2010 (Matematica e cultura)
by Michele EmmerLa collana Matematica e cultura, attraverso un cammino iniziato dodici anni fa, in modo sempre nuovo, sorprendente e affascinante prova a descrivere influenze e legami esistenti tra il mondo della matematica e quello del cinema, della musica, dell'economia, ma anche dell’arte, del teatro, della letteratura o della storia
Materia prima: Zur Semantik des Begriffs in naturkundlichen Sachschriften des 16. Jahrhunderts (Edition Centaurus – Neuere Medizin- und Wissenschaftsgeschichte)
by Katharina DückKatharina Dück widmet sich in diesem Buch dem umfangreichen Doktrinenschatz des Begriffs „Materia prima“ im Spannungsfeld von Theorie und wiederholbarer Praxis in deutschsprachigen alchemisch-naturkundlichen Sachschriften des 16. Jahrhunderts. Sie trägt damit neue Aspekte zur Debatte des Materialismus in der Frühen Neuzeit bei. Untersucht werden Texte sogenannter Meisterdenker als auch Zeugnisse derer, die bisher wenig berücksichtigt wurden. Dem Corpus Paracelsicum und der Strömung des Paracelsismus wird besondere Beachtung gezollt. Drei rasterartig umrissene Grundmuster, denen die „Materia prima“-Vorstellungen zugeordnet sind, werden ausführlich vorgestellt und dabei Kontinuitäten sowie Transformationen von vorhandenen Materie-Konzepten festgestellt.
Material Agency: Towards a Non-Anthropocentric Approach
by Carl Knappett Lambros MalafourisThus far an ‘agent’ in the social sciences has always meant someone whose actions bring about change. In this volume, the editors challenge this position and examine the possibility that agency is not a solely human property. Instead, this collection of archaeologists, anthropologists, sociologists and other social scientists explores the symbiotic relationships between humans and material entities (a key opening a door, a speed bump raising a car) as they engage with one another.
Material Beings
by Peter van Van InwagenAccording to Peter van Inwagen, visible inanimate objects do not, strictly speaking, exist. In defending this controversial thesis, he offers fresh insights on such topics as personal identity, commonsense belief, existence over time, the phenomenon of vagueness, and the relation between metaphysics and ordinary language.
Material Christianity: Western Religion and the Agency of Things (Sophia Studies in Cross-cultural Philosophy of Traditions and Cultures #32)
by Christopher Ocker Susanna ElmThis collection of essays offers a series of rigorously focused art-historical, historical, and philosophical studies that examine ways in which materiality has posed and still poses a religious and cultural problem. The volume examines the material agency of objects, artifacts, and environments: art, ritual, pilgrimage, food, and philosophy. It studies the variable "senses” of materiality, the place of materiality in the formation of modern Western religion, and its role in Christianity’s dialogue with non-Western religions. The essays present new interpretations of religious rites and outlooks through the focus on their material components. They also suggest how material engagement theory - a new movement in cultural anthropology and archeology - may shed light on the cultural history of Christianity in medieval and early modern Europe and the Americas. It thus fills an important lacuna in the study of western religion by highlighting the longue durée, from the Middles Ages to the Modern Period, of a current dilemma, namely the divide between materialistic and what might broadly be called hermeneutical or cultural-critical approaches to religion and human subjectivity.
Material Ethics of Value: Max Scheler and Nicolai Hartmann (Phaenomenologica #203)
by E. KellyMax Scheler and Nicolai Hartmann developed ethics upon a phenomenological basis. This volume demonstrates that their contributions to a material ethics of value are complementary: by supplementing the work of one with that of the other, we obtain a comprehensive and defensible axiological and moral theory. By “phenomenology,” we refer to an intuitive procedure that attempts to describe thematically the insights into essences, or the meaning-elements of judgments, that underlie and make possible our conscious awareness of a world and the evaluative judgments we make of the objects and persons we encounter in the world.
Material Game Studies: A Philosophy of Analogue Play
by Chloé Germaine and Paul WakeThis is the first volume to apply insights from the material turn in philosophy to the study of play and games. At a time of renewed interest in analogue gaming, as scholars are looking beyond the digital and virtual for the first time since the inception of game studies in the 1990s, Material Game Studies not only supports the importance of the (re)turn to the analogue, but proposes a materiality of play more broadly. Recognizing the entanglement of physical materiality with cultural meaning, the authors in this volume apply a range of theoretical approaches, from material eco-criticism to animal studies, to examine games and play as existing within worlds of matter. Different chapters focus on the material properties of board, card and role-playing games, how they are designed and made, how they are touched and played with, and how they connect with other human and nonhuman things. Bringing together international scholars, Material Game Studies defines a new field of material game studies and demonstrates how it is a valuable addition to wider debates about the material turn and the place of embodied humans in a material world.

Material Objects in Confucian and Aristotelian Metaphysics: The Inevitability of Hylomorphism
by James Dominic RooneyHylomorphism is a metaphysical theory that explains the unity of material objects through a special immaterial part, a 'form'. While contemporary accounts of hylomorphism appeal to structure, and advocate that material substances can have other substances as parts, James Dominic Rooney highlights the flaws in this Neo-Aristotelian way of thinking. Instead, he draws on medieval European and Chinese traditions to put forward that the classical approach to the unity of material objects in terms of 'form' remains theoretically superior. Rooney shows how Thomas Aquinas' account of form gives a more coherent version of hylomorphism, eliminating the need for substance parts. He also studies the Song dynasty Confucian thinker Zhu Xi's hylomorphic intuition that whatever accounts for the composition of some parts into a material whole is a metaphysical part of that object. By appealing to the same non-Aristotelian considerations as Zhu Xi, Rooney explains why all those who believe in the unity of material objects will appeal to a form, enabling hylomorphism to remain a plausible framework. In doing so, this book shines new light on a classic philosophical problem in contemporary metaphysics and demonstrates the far-reaching points of theoretical contact between Western and Confucian thought.

Material Practice and Materiality: Too Long Ignored in Science Education (Cultural Studies of Science Education #18)
by Kathryn Scantlebury Catherine MilneIn this book various scholars explore the material in science and science education and its role in scientific practice, such as those practices that are key to the curriculum focuses of science education programs in a number of countries.As a construct, culture can be understood as material and social practice. This definition is useful for informing researchers' nuanced explorations of the nature of science and inclusive decisions about the practice of science education (Sewell, 1999). As fields of material social practice and worlds of meaning, cultures are contradictory, contested, and weakly bounded. The notion of culture as material social practices leads researchers to accept that material practice is as important as conceptual development (social practice).However, in education and science education there is a tendency to ignore material practice and to focus on social practice with language as the arbiter of such social practice. Often material practice, such as those associated with scientific instruments and other apparatus, is ignored with instruments understood as "inscription devices", conduits for language rather than sources of material culture in which scientists share “material other than words” (Baird, 2004, p. 7) when they communicate new knowledge and realities. While we do not ignore the role of language in science, we agree with Barad (2003) that perhaps language has too much power and with that power there seems a concomitant loss of interest in exploring how matter and machines (instruments) contribute to both ontology and epistemology in science and science education.
The Material Realization of Science: From Habermas to Experimentation and Referential Realism (Boston Studies in the Philosophy and History of Science #294)
by Hans RadderThis book develops a conception of science as a multi-dimensional practice, which includes experimental action and production, conceptual-theoretical interpretation, and formal-mathematical work. On this basis, it addresses the topical issue of scientific realism and expounds a detailed, referentially realist account of the natural sciences. This account is shown to be compatible with the frequent occurrence of conceptual discontinuities in the historical development of the sciences. Referential realism exploits several fruitful ideas of Jürgen Habermas, especially his distinction between objectivity and truth; it builds on a in-depth analysis of scientific experiments, including their material realization; and it is developed through an extensive case study in the history and philosophy of quantum mechanics. The new postscript explains how the book relates to several important issues in recent philosophy of science and science studies.“I highly recommend this book. Radder is probably the first philosopher of science to make productive epistemological use of the notion of ‘experimental system’. The postscript is most valuable since it connects his work not only to the topical debates in philosophy of science, but also to history of science and science studies.”Hans-Jörg Rheinberger, Max Planck Institute for the History of Science, BerlinAbout the first edition:“The debate on realism has recently become rather stale by repetition, but Radder introduces original insights and has written a lively and well-argued contribution to it. The book is to be recommended also as a clear introduction to the complex of relevant issues.”Mary Hesse, University of Cambridge“Radder presents an ingenious approach to the issue of scientific realism and conceptual discontinuity. I believe his idea that conceptual discontinuity presupposes other types of continuity is extremely important.”Mark Rowlands, University of Alabama, Tuscaloosa Hans Radder is professor of philosophy of science and technology at VU University Amsterdam. He is the author of In and About the World and The World Observed/The World Conceived. He edited The Philosophy of Scientific Experimentation and The Commodification of Academic Research: Science and the Modern University, and is coeditor of Science Transformed? Debating Claims of an Epochal Break.

Materialism: A Historical and Philosophical Inquiry
by Robin Gordon Brown James LadymanThe doctrine of materialism is one of the most controversial in the history of ideas. For much of its history it has been aligned with toleration and enlightened thinking, but it has also aroused strong, often violent, passions amongst both its opponents and proponents. This book explores the development of materialism in an engaging and thought-provoking way and defends the form it takes in the twenty-first century. Opening with an account of the ideas of some of the most important thinkers in the materialist tradition, including Epicurus, Lucretius, Hobbes, Hume, Darwin and Marx, the authors discuss materialism’s origins, as an early form of naturalistic explanation and as an intellectual outlook about life and the world in general. They explain how materialism’s beginnings as an imaginative vision of the true nature of things faced a major challenge from the physics it did so much to facilitate, which now portrays the microscopic world in a way incompatible with traditional materialism. Brown and Ladyman explain how out of this challenge materialism developed into the new doctrine of physicalism. Drawing on a wide range of colourful examples, the authors argue that although materialism does not have all the answers, its humanism and commitment to naturalistic explanation and the scientific method is our best philosophical hope in the ideological maelstrom of the modern world.

Materialism
by Terry EagletonA brilliant introduction to the philosophical concept of materialism and its relevance to contemporary science and culture In this eye-opening, intellectually stimulating appreciation of a fascinating school of philosophy, Terry Eagleton makes a powerful argument that materialism is at the center of today’s important scientific and cultural as well as philosophical debates. The author reveals entirely fresh ways of considering the values and beliefs of three very different materialists—Marx, Nietzsche, and Wittgenstein—drawing striking comparisons between their philosophies while reflecting on a wide array of topics, from ideology and history to language, ethics, and the aesthetic. Cogently demonstrating how it is our bodies and corporeal activity that make thought and consciousness possible, Eagleton’s book is a valuable exposition on philosophic thought that strikes to the heart of how we think about ourselves and live in the world.
Materialism and Dialectics in a Post-classical World: Impact of Electromagnetism
by Anil RajimwaleEvolution of the concepts of atom and atomism, and the impact of electromagnetism on our worldview, is the object of our study in this book. Electromagnetism is the key link in the transition from classical to post-classical worldview. This transition is caused by the one from our thought based upon the tangibles to that based upon the intangibles. Electromagnetism inaugrated an era of light speeds and near it, and of the world constituted by such speeds. Philosophy and the worldview need to catch up and undergo a basic change. Atom as a concept and reality is under severe stress as explanation of reality. Reality has come out of atomic limits and unveiled a new world, which is constituted of quantum, relativity, wave/particle duality, etc. It is a challenge to philosophy, which re-fashioning to interpret the post-classical world based on rapid motions.We need to develop new concepts and bring about a realignment in various thought constituents. Rather thatn 'overthrow' matter, we are delving deeper into it. Philosophy and human thought itself stands on the brink of redefinition. In the present book the author shows how electromagnetism connects classical with post-classical thought, creating new structures, and impacting materialism and dialectics. This book is co-published with Aakar Books, New Delhi. Taylor & Francis does not sell or distribute the print versions of this book in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.

Materialism from Hobbes to Locke
by Stewart DuncanAre human beings purely material creatures, or is there something else to them, an immaterial part that does some (or all) of the thinking, and might even be able to outlive the death of the body? This book is about how a series of seventeenth-century philosophers tried to answer that question. It begins by looking at the views of Thomas Hobbes, who developed a thoroughly materialist account of the human mind, and later of God as well. This is in obvious contrast to the approach of his contemporary René Descartes. After examining Hobbes's materialism, Stewart Duncan considers the views of three of his English critics: Henry More, Ralph Cudworth, and Margaret Cavendish. Both More and Cudworth thought Hobbes's materialism radically inadequate to explain the workings of the world, while Cavendish developed a distinctive, anti-Hobbesian materialism of her own. The second half of the book focuses on the discussion of materialism in John Locke's Essay concerning Human Understanding, arguing that we can better understand Locke's discussion if we see how and where he is responding to this earlier debate. At crucial points Locke draws on More and Cudworth to argue against Hobbes and other materialists. Nevertheless, Locke did a good deal to reveal how materialism was a genuinely possible view, by showing how one could develop a detailed account of the human mind without presuming it was an immaterial substance. This work probes the thought and debates that originated in the seventeenth-century yet extended far beyond it. And it offers a distinctive, new understanding of Locke's discussion of the human mind.

Materialism: A Historico-Philosophical Introduction (SpringerBriefs in Philosophy #0)
by Charles T. WolfeThis book provides an overview of key features of (philosophical) materialism, in historical perspective. It is, thus, a study in the history and philosophy of materialism, with a particular focus on the early modern and Enlightenment periods, leading into the 19th and 20th centuries. For it was in the 18th century that the word was first used by a philosopher (La Mettrie) to refer to himself. Prior to that, ‘materialism’ was a pejorative term, used for wicked thinkers, as a near-synonym to ‘atheist’, ‘Spinozist’ or the delightful ‘Hobbist’. The book provides the different forms of materialism, particularly distinguished into claims about the material nature of the world and about the material nature of the mind, and then focus on materialist approaches to body and embodiment, selfhood, ethics, laws of nature, reductionism and determinism, and overall, its relationship to science. For materialism is often understood as a kind of philosophical facilitator of the sciences, and the author want to suggest that is not always the case. Materialism takes on different forms and guises in different historical, ideological and scientific contexts as well, and the author wants to do justice to that diversity. Figures discussed include Lucretius, Hobbes, Gassendi, Spinoza, Toland, Collins, La Mettrie, Diderot, d’Holbach and Priestley; Büchner, Bergson, J.J.C. Smart and D.M. Armstrong.
Materialist Media Theory: An Introduction
by Grant BollmerOur technologies rely on an ever-expanding infrastructure of wires, routers, servers, and hard drives-a proliferation of devices that reshape human interaction and experience prior to conscious knowledge. Understanding these technologies requires an approach that foregrounds media as an agent that collaborates in the production of the world beyond content or representation. Materialist Media Theory provides an accessible, synthetic account of the cutting edge of the theoretical humanities, examining a range of approaches to media's physical, infrastructural role in shaping culture, space, time, cognition, and life itself. More than a mere introduction, Materialist Media Theory provides a critical intervention into matter and media, of interest to students and researchers in media studies, communication, cultural studies, visual culture, and beyond. Media determine our reality, and any politics of media must begin by foregrounding the media's materiality.
