Foraging is a central competence of all mobile organisms. Models and concepts from foraging theory have been applied widely throughout biology to the search for many kinds of external resources, including food, sexual encounters, minerals, water, and the like. In cognitive science and neuroscience, the tools of foraging theory are increasingly applied to a wide range of other types of search, including for abstract resources like information or for internal resources like memories, concepts, and strategies for problem solving. Despite its (...) importance in ecology and increasing relevance for the study of cognition, the concept of foraging is rarely analyzed. Here, I aim to rectify this situation. I outline three desiderata: first, an analysis should differentiate foraging from search and decision making more generally; second, an analysis should unify different types of foraging; and third, an analysis should help ground predictions. I present an analysis of foraging as the serial search for general resources in accept-or-reject, exclusive, persistent decision contexts. Not all search is serial and not all decision making is exclusive, differentiating foraging from search and decision making generally. With the aid of Markov decision processes and directed cyclical models, I show how the analysis implies a cyclical graph. This cyclical graph is embedded in the description of many types of foraging, unifying the different instances. Finally, I argue that the cyclical graph is also embedded in representations of novel task contexts that have not previously been viewed as foraging. I illustrate this novel application of the concept of foraging by arguing that reasoning is a type of foraging. (shrink)

The dynamical hypothesis states that cognitive systems are dynamical systems. While dynamical systems play an important role in many cognitive phenomena, the dynamical hypothesis as stated applies to every system and so fails both to specify what makes cognitive systems distinct and to distinguish between proposals regarding the nature of cognitive systems. To avoid this problem, I distinguish several different types of dynamical systems, outlining four dimensions along which dynamical systems can vary: total-state versus partial-state, internal versus external, macroscopic versus (...) microscopic, and systemic versus componential, and illustrate these with examples. I conclude with two illustrations of partial-state, internal, microscopic, componential dynamicism. (shrink)

In this essay, David Hildebrand connects Democracy and Education to Dewey's wider corpus. Hildebrand argues that Democracy and Education's central objective is to offer a practical and philosophical answer to the question, What is needed to live a meaningful life, and how can education contribute? He argues, further, that this work is still plausible as “summing up” Dewey's overall philosophy due to its focus upon “experience” and “situation,” crucial concepts connecting Dewey's philosophical ideas to one another, to education, and (...) to democracy. He opens the essay with a brief synoptic analysis of Democracy and Education's major philosophical ideas, moves on to sections devoted to experience and situation, and then offers a brief conclusion. Some mention is made throughout about the surprisingly significant role art and aesthetics can play in education. (shrink)

Overview of challenges facing philosophical analyses of experience in the face of life with constant connection, social media, and data mining.

Through photographs and translations of Friedrich Nietzsche's evocative writings on his work sites, David Farrell Krell and Donald L. Bates explore the cities and landscapes in which Nietzsche lived and worked.

Schools of Faith represents a diversity of essays from scholars in several continents. The contributors, all leading theologians and ethicists, offer reflections on historical and contemporary themes which are significant for wider debates in theological education and church life in today's world. The range of contributor and content provides a fitting tribute to the work of Iain R. Torrance over many years. Amid the numerous subjects discussed, the authors focus on liturgy, textual criticism, public theology, the ethics of war, Christian (...) doctrine, divine action, ecumenism, inter-faith dialogue, spiritual formation, the office of the minister, and the interface between religion and literature. The multi-faceted nature of this collection signifies its importance for historical, systematic and practical theology. (shrink)

One of Aristotle's logic treatises, this text is published in the Oxford Classical Text series.

What did C. S. Lewis think about truth, goodness and beauty? Fifteen essays explore three major philosophical themes from the writings of Lewis--Truth, Goodness and Beauty. This volume provides a comprehensive overview of Lewis's philosophical thinking on arguments for Christianity, the character of God, theodicy, moral goodness, heaven and hell, a theory of literature and the place of the imagination.

Qu'est-ce qui oriente la philosophie? Depuis Platon, le philosophe est celui qui tourne son regard vers le Bien et qui adopte une manière de vivre en accord avec sa pensée. Qu'est devenue cette manière de vivre comme exigence philosophique, pour un philosophe qui se laisse inspirer par la révélation chrétienne? Faut-il la nommer "sainteté"? Cet ouvrage présente six philosophes du XXe siècle qui ont cherché à accorder leur pensée et leur manière de vivre : Maurice Blondel, Erich Przywara, Simone Weil, (...) Aimé Forest, Michel Henry, Edith Stein. Des philosophes à l'écoute d'une inspiration qui oriente leur existence. La philosophie comme un acte de résistance spirituelle. Il y a là beaucoup à apprendre. (shrink)

At a time when politics and virtue seem less compatible than oil and water, _Democracy and Moral Development_ shows how to bring the two together. Philosopher David Norton applies classical concepts of virtue to the premises of modern democracy. The centerpiece of the book is a model of organizational management applicable to the state, business, the professions, and voluntary communities.

Criticized as a nostalgic anachronism by those who oppose her version of political theory and lauded as symbol of direct democratic participation by those who favor it, the Athenian polis features prominently in Hannah Arendt's account of politics. This essay traces the origin and development of Arendt's conception of the polis as a space of appearance from the early 1950s onward. It makes particular use of the Denktagebuch, Arendt's intellectual diary, in order to shed new light on the historicity of (...) one of her central concepts. The article contends that both critics and partisans of Arendt's use of the polis have made the same mistake: they have presumed that the polis represents a space of face-to-face immediacy. In fact, Arendt compared the polis to a series of analogues, many of which are not centered on direct exchanges between political actors and spectators. As a result, Arendt's early work on the polis turns out to anticipate many of the concerns of her later work on judgment, and her theory of the polis becomes a theory of topics. (shrink)

By ruling out questions of impairment from the social critique of disability, Disability Studies analyses establish a limit point in the field. Of course the setting of “limits” enables possibilities in multiple directions as well as fortifies boundaries of refusal. For instance, impairment becomes in DS simultaneously a productive refusal to interpret disabled bodies as inferior to non-disabled bodies and a bar to thinking through more active engagements with disability as materiality. Disability materiality such as conditions produced by ecological toxicities (...) serve as active switch-points for creative corporeal navigations of the interaction between bodies and environments.In fact in this paper we want to propose a more “lively” definition of disability materiality to existing definitions of impairment as limiting expressions of non-normative bodies. We have no useful ways of explaining disability as adaptation and it’s time we begin the process of theorizing more active ideas of materiality that extend existing ideas of disability beyond simplistic conceptions of socially rejected biologies made available by social constructivist thought.

Individuals with autistic spectrum disorder (ASD) display diverse deficits in social, cognitive and behavioral functioning. To date, there has been mixed findings on the profile of executive function deficits for high-functioning adults (IQ >70) with ASD. A conceptual distinction is commonly made between “cold” and “hot” executive functions. Cold executive functions refer to mechanistic higher-order cognitive operations (e.g., working memory), whereas hot executive functions entail cognitive abilities supported by emotional awareness and social perception (e.g., social cognition). This study aimed to (...) determine the independence of deficits in hot and cold executive functions for high-functioning adults with ASD. Forty-two adults with ASD (64% male, aged 18-66 years) and 40 age and gender matched controls were administered The Awareness of Social Inference Test (TASIT; emotion recognition and social inference), Letter Number Sequencing (working memory) and Hayling Sentence Completion Test (response initiation and suppression). Between-group analyses identified that the ASD group performed significantly worse than matched controls on all measures of cold and hot executive functions (d =.54-1.5). Hierarchical multiple regression analyses revealed that the ASD sample performed more poorly on emotion recognition and social inference tasks than matched controls after controlling for cold executive functions and employment status. The findings also indicated that the ability to recognise emotions and make social inferences was supported by working memory and response initiation and suppression processes. Overall, this study supports the distinction between hot and cold executive function impairments for adults with ASD. Moreover, it advances understanding of higher-order impairments underlying social interaction difficulties for this population which, in turn, may assist with diagnosis and inform intervention programs.

Definitions of pragmatism increasingly turn on understanding and relating the philosophies of Richard Rorty and John Dewey. Rorty is often the first and most important lens through which many encounter pragmatism or Dewey; thus, it is crucial to know where “Rorty” ends and where “Dewey” begins. To find that line, this chapter answers the question: What did Rorty believe Dewey contributed to pragmatism, to philosophy, and to humanity? After reviewing how Rorty's personal and academic beginnings intertwined with Dewey, preliminary context (...) is provided by reviewing Rorty's view of pragmatism and neopragmatism and his general interpretive approach to Dewey. These preliminaries yield to analytical descriptions of the main areas in Dewey's work which Rorty was concerned to present: experience; objectivity and truth; inquiry and scientific method; ethics, politics, and democracy; and, finally, the general purpose of philosophy.

El darwinismo, especialmente en la forma de la síntesis moderna, es una de las teorías más influyentes en la comunidad científica internacional. Sin embargo, esta interpretación del mecanismo evolutivo, presentado a la manera de una doctrina intangible e indiscutible, le da un estatus de ortodoxia, incluso de ideología. Además, durante muchos años, un número creciente de investigadores piden un camino más allá del darwinismo mediante la adopción de un enfoque sistémico y una visión menos enfocada, más abierta y realista, que (...) conduzca a una profunda redefinición de los conceptos evolutivos fundamentales. De hecho, el descubrimiento de mecanismos naturales de ingeniería genética muestra que las células vivas tienen la capacidad de insertar y reestructurar información dentro de su propio material genético, a diferentes escalas, incluso a nivel genómico, y así producir innovaciones que son significativas desde un punto de vista evolutivo (cooperatividad, redundancia, rehabilitación). El cambio de paradigma provocado por esta perspectiva teleológica sobre el funcionamiento de los organismos vivos podría tomar la escala de una revolución científica. (shrink)

"Legend is overdue for replacement, and an adequate replacement must attend to the process of science as carefully as Hull has done. I share his vision of a serious account of the social and intellectual dynamics of science that will avoid both the rosy blur of Legend and the facile charms of relativism.... Because of [Hull's] deep concern with the ways in which research is actually done, Science as a Process begins an important project in the study of science. It (...) is one of a distinguished series of books, which Hull himself edits."—Philip Kitcher, Nature "In Science as a Process, [David Hull] argues that the tension between cooperation and competition is exactly what makes science so successful.... Hull takes an unusual approach to his subject. He applies the rules of evolution in nature to the evolution of science, arguing that the same kinds of forces responsible for shaping the rise and demise of species also act on the development of scientific ideas."—Natalie Angier, New York Times Book Review "By far the most professional and thorough case in favour of an evolutionary philosophy of science ever to have been made. It contains excellent short histories of evolutionary biology and of systematics (the science of classifying living things); an important and original account of modern systematic controversy; a counter-attack against the philosophical critics of evolutionary philosophy; social-psychological evidence, collected by Hull himself, to show that science does have the character demanded by his philosophy; and a philosophical analysis of evolution which is general enough to apply to both biological and historical change."—Mark Ridley, Times Literary Supplement "Hull is primarily interested in how social interactions within the scientific community can help or hinder the process by which new theories and techniques get accepted.... The claim that science is a process for selecting out the best new ideas is not a new one, but Hull tells us exactly how scientists go about it, and he is prepared to accept that at least to some extent, the social activities of the scientists promoting a new idea can affect its chances of being accepted."—Peter J. Bowler, Archives of Natural History "I have been doing philosophy of science now for twenty-five years, and whilst I would never have claimed that I knew everything, I felt that I had a really good handle on the nature of science, Again and again, Hull was able to show me just how incomplete my understanding was.... Moreover, [Science as a Process] is one of the most compulsively readable books that I have ever encountered."—Michael Ruse, Biology and Philosophy. (shrink)

In the context of deceased organ donation, donors are routinely tested for HIV, to check for suitability for organ donation. This article examines whether a donor’s HIV status should be disclosed to the donor’s next of kin.On the one hand, confidentiality requires that sensitive information not be disclosed, and a duty to respect confidentiality may persist after death. On the other hand, breaching confidentiality may benefit third parties at risk of having been infected by the organ donor, as it may (...) permit them to be tested for HIV and seek treatment in case of positive results.We conclude that the duty to warn third parties surpasses the duty to respect confidentiality. However, in order to minimize risks linked to the breach of confidentiality, information should be restrained to only concerned third parties, that is, those susceptible to having been infected by the donor.

After briefly narrating the evolution of Western ethical reflections on suicide and euthanasia, I argue that because people have a prima facie right not to be killed, it is usually unethical to kill anyone who poses no imminent lethal threat to others or who has not committed a capital crime. But I’m also persuaded that some instances of mercy killing in war are not only morally justifiable, they can be more ethical than allowing someone to die in agony and distress (...) from their wounds. Thus I am uncomfortable with the current strict prohibition on battlefield euthanasia in the Geneva Conventions, which I think unfairly punishes some morally justified acts. But after considering the potential consequences of legalizing battlefield euthanasia, I conclude nonetheless that it is best to leave the prohibition intact. (shrink)

Searching for the meaning of “truth” in the Chinese tradition would not immediately strike one as a controversial activity. The signal prominence of the quest for truth in shaping the sensibility of Anglo‐European culture might easily suggest that the notion has had a similar import in China. But the fact of the matter is that scholars from China, Europe, and America continue to debate the question as to whether there is even anything like a concept of “truth” in China. On (...) the surface, the claim that the Chinese have no concept of truth appears outrageous – surely the Chinese tell the truth as often as we, and lie as often. Even granting that this is the case, it turns out, nonetheless, that the issue is not as easily settled as one might think. (shrink)

This book seeks to elucidate the concept of justice, not so much as it is expressed in law courts (retributive and procedural justice) or in state budgets (distributive justice), but as primary justice - what it means and how it can be grounded in the inalienable rights that each human being possesses qua human being. It draws inspiration from two recent works of philosopher Nicolas Wolterstorff, but also from the groundbreaking Islamic initiative of 2007, the Common Word Letter addressed by (...) 138 eminent Muslim scholars and clerics to the pope and all Christian leaders. This document affirmed that the two highest commandments in both Judaism and Christianity are also at the heart of the Islamic tradition - love of God and love of neighbor. In a style that lends itself to the classroom and beyond, the book's six chapters all begin with a case study of justice, so as to emphasize that justice must also be embodied in righteous social, political and economic practices. Along the way, leading contemporary scholars and activists from both traditions urge the reader - Muslim, Christian, or whatever - to look afresh at an age-old conundrum: how do justice and love interact so as to create a world in which everyone finds his or her rightful place?

And, finally, this line of inquiry is exemplified and interrogated by means of a concrete historiographic case—namely, a political theoretical investigation of the intellectual legacy of the Weimar Republic.

Several important terms in biology have recently been criticized for not being "operational." In this paper the course of operationism in physics, psychology and genetics is sketched to show what effect this particular view on the meaning of scientific terms had on these disciplines. Then the biological species concept and the concept of homology are examined to see in what respects they are or are not "operational." One of the primary conclusions of this investigation is that few terms in science (...) are completely operational or completely nonoperational. Some scientific terms, especially theoretical terms, are a good deal less operational than others; but, far from being regrettable, this situation is essential if theoretical terms are to fulfill their systematizing function and if scientific theories are to be capable of growth.

Will democracy figure prominently in China's future? If so, what kind of democracy? In this insightful and thought-provoking book, David Hall and Roger Ames explore such questions and, in the course of answering them, look to the ideas of John Dewey and Confucius.

Drawing on work of the past decade, this volume brings together articles from the philosophy, history, and sociology of science, and many other branches of the biological sciences. The volume delves into the latest theoretical controversies as well as burning questions of contemporary social importance. The issues considered include the nature of evolutionary theory, biology and ethics, the challenge from religion, and the social implications of biology today (in particular the Human Genome Project).

Compares classic and contemporary theories of genetics and evolution and explores the role of teleological thought in biology.

The author proposes a system of identification, positional, and phyletic numbers for taxa that makes possible a significant relationship between numerical classification and phylogeny.
