Highly idealized models, such as the Hawk-Dove game, are pervasive in biological theorizing. We argue that the process and motivation that leads to the introduction of various idealizations into these models is not adequately captured by Michael Weisberg’s taxonomy of three kinds of idealization. Consequently, a fourth kind of idealization is required, which we call hypothetical pattern idealization. This kind of idealization is used to construct models that aim to be explanatory but do not aim to be explanations.

Written by five scholars whose expertise extends across the disciplines of biblical, historical, systematic, and philosophical theology, this is a careful and ...

A number of thinkers today, including open theists, find reasons to attribute temporality to God. According to Robert W. Jenson, the Trinity is indispensable to a Christian concept of God, and divine temporality is essential to the meaning of the Trinity. Following the lead of early Christian thought, Jenson argues that the persons of the Trinity are relations, and these relations are temporal. Jenson’s insights are obscured, however, by problematic references to time as a sphere to which God is related. (...) Schubert M. Ogden gives the notion of divine temporality coherent content by arguing that God’s actuality is best understood as an unending succession of experiences. This paper was delivered in the APA Pacific 2007 Mini-Conference on Models of God. (shrink)

Substantial research demonstrates that ethical leaders improve a broad range of outcomes for their employees, but considerably less attention has been devoted to the performance and success of the leaders themselves. The present study explores the extent to which being ethical relates to leaders’ performance and promotability. We address this question by examining ethical leadership from the two ethical perspectives most common in Western traditions—i.e., the “right” and the “good”—and whether one might be more closely associated than the other with (...) performance and promotability evaluations. Results from 117 employee-supervisor-manager triads show that supervisors with a deontological outlook are more likely to be seen as ethical leaders and that utilitarian leaders are more likely to earn higher performance evaluations. We discuss the implications of these findings for research on ethical leadership. (shrink)

Edited by Richard Grusin of the Center for 21st Century Studies, this is the first book to name and characterize—and therefore consolidate—a wide array of current critical, theoretical, and philosophical approaches to the humanities and social sciences under the concept of the nonhuman turn. Each of these approaches is engaged in decentering the human in favor of a concern for the nonhuman, understood by contributors in a variety of ways—in terms of animals, affectivity, bodies, materiality, technologies, and organic and (...) geophysical systems. The nonhuman turn in twenty-first-century studies can be traced to multiple intellectual and theoretical developments from the last decades of the twentieth century: actor-network theory, affect theory, animal studies, assemblage theory, cognitive sciences, new materialism, new media theory, speculative realism, and systems theory. Such varied analytical and theoretical formations obviously diverge and disagree in many of their assumptions, objects, and methodologies. However, they all take up aspects of the nonhuman as critical to the future of twenty-first-century studies in the arts, humanities, and social sciences. Unlike the posthuman turn, the nonhuman turn does not make a claim about teleology or progress in which we begin with the human and see a transformation from the human to the posthuman. Rather, the nonhuman turn insists (paraphrasing Bruno Latour) that “we have never been human,” that the human has always coevolved, coexisted, or collaborated with the nonhuman—and that the human is identified precisely by this indistinction from the nonhuman.

No point of John C.Calhoun's political thought has been more disputed than exactly where it is situated in the theoretical landscape. Calhoun has been treated as the �Marx of the master class� by Richard Hofstadter; a �reactionary conservative� arguing eclectically from liberal premises by Louis Hartz; an authentic conservative by Russell Kirk, Clinton Rossiter and August Spain; and a precursor to the pluralist vision of politics by Peter Drucker. Two of the most engaging treatments of Calhoun's thought are Darryl (...) Baskin's and Peter Steinberger's, both of relatively recent vintage. Baskin argues that despite Calhoun's use of vocabulary borrowed from organic conservatism he is essentially a classical liberal and, as such, is engaged in the typically liberal �flight from community�. He has no true notion of civic virtue and his concept of the public interest is only a mechanistic sum of private interests. Steinberger agrees that Calhoun is a liberal, but argues that his contribution to American liberalism is precisely to sublate selfishness to an authentic civic virtue. These disputes are interesting, but I suggest that in the efforts to contain Calhoun within the conservative/liberal scheme of categorization some of the subtlety of his thought is lost. Too often an appreciation of his thought is sacrificed to an underlying agenda of attacking or defending one ideology or another. In the present critique I attempt to recover some insights that have been submerged in other treatments. Calhoun's constitutional theory of concurrent majoritarianism, rather than his liberal or conservative bent, is the focal point of sections III and IV. I argue that Calhoun's theory exposes -- sometimes unwittingly -- the stern limits of what constitutions can accomplish. In section V I suggest that insofar as Calhoun is generally a liberal (as Hartz, Baskin and Steinberger contend) an internal contradiction within his theory points to a paradox at the very heart of liberalism.

Plant genome editing has the potential to become another chapter in the intractable debate that has dogged agricultural biotechnology. In 2016, 107 Nobel Laureates accused Greenpeace of emotional and dogmatic campaigning against agricultural biotechnology and called for governments to defy such campaigning. The Laureates invoke the authority of science to argue that Greenpeace is putting lives at risk by opposing agricultural biotechnology and Golden Rice and is notable in framing Greenpeace as unethical and its views as marginal. This paper (...) examines environmental, food and farming NGOs’ social and ethical concerns about genome editing, situating these concerns in comparison to alternative ethical assessments provided by the Nuffield Council on Bioethics, a key actor in this policy debate. In doing so, we show that participant NGOs and the Nuffield Council on Bioethics share considerable concerns about the social and ethical implications of genome editing. These concerns include choices over problem/solution framing and broader terminology, implications of regulatory and research choices on consumer choice and relations of power. However, GM-engaged NGOs and the Nuffield Council on Bioethics diverge on one important area: the NGOs seek to challenge the existing order and broaden the scope of debate to include deeply political questions regarding agricultural and technological choices. This distinction between the ethical positions means that NGOs provide valuable ethical insight and a useful lens to open up debate and discussion on the role of emerging technologies, such as genome editing, and the future of agriculture and food sovereignty.

This anthology is a significant contribution to the debate over the relevance of Martin Heidegger's Nazi ties to the interpretation and evaluation of his philosophical work. Included are a selection of basic documents by Heidegger, essays and letters by Heidegger's colleagues that offer contemporary context and testimony, and interpretive evaluations by Heidegger's heirs and critics in France and Germany.In his new introduction, "Note on a Missing Text," Richard Wolin uses the absence from this edition of an interview with Jacques (...) Derrida as a springboard for examining questions about the nature of authorship and personal responsibility that are at the heart of the book.Richard Wolin is Professor of Modern European Intellectual History and Humanities at Rice University. He is the author of Walter Benjamin, The Politics of Being: The Political Thought of Martin Heidegger, and The Terms of Cultural Criticism: The Frankfurt School, Existentialism and Poststructuralism.

In lieu of an abstract, here is a brief excerpt of the content:Building a FoundationRichard KeidanA guiding principle of Judaism is "tzedakah," which translates as charity but actually means righteousness, reflecting that tzedakah is an obligation, not a choice. This concept of social justice was taught to me at home, at school and at synagogue. I gave to charities and did occasional charitable work. As my parents had taught me, I taught my own children the spirit of giving, but it (...) did come from a place of obligation, not passion. I have since come to learn that there is a world of difference between just fulfilling our obligations to each other and letting them guide the kind of person we become.It is ironic how the process of becoming a doctor—a person society expects to be selfless— requires total self-absorption. Think about it. I was trained to compete with my classmates in order to be accepted to the best university, medical school, residency, and then fellowship. I spent more than one hundred hours each week in the hospital during surgical residency. If I had free time, I wanted to do what I wanted to do. I was so focused on the end result that I had little time to think of others, let alone to ponder the inequities of the world.Several events led to the awakening of my conscience. One was an opportunity to go to Ethiopia and perform a couple weeks' worth of cancer surgery through Mother Teresa's Clinic. Quite frankly, I went because it seemed like an exciting adventure. However, I was completely overwhelmed by the experience. The conditions were abominable. The stories of each of my patients were heart-wrenching. I encountered a 14-year-old boy, the same age as my son, who had a tumor 15 cm in thickness wrapped around his neck. In order to hide the tumor he wore a scarf, but this still did not prevent him from being shunned. He traveled by himself for several days on a bus to reach the clinic. He had no one to advocate on his behalf, was unable to speak the local language, had never been outside his village (let alone in a motor vehicle), and he fearlessly underwent major surgery all by himself.The inequalities in health care compared to my suburban hospital were unfathomable. I cried every night in my hotel room. There seemed to be no solution to this situation. Soon after I returned home, Ethiopia became a distant memory. The experience cut me to the bone, but for whatever reason, I did not rally. I did not see myself as part of the solution. It took an entirely different international experience to open my eyes.There is a saying, "One goes to the Himalayas to see the mountains, but returns for the culture." In 1982, on a sabbatical from my surgical training, I went to Nepal to see the Himalayas, but fell in love with the people. Living in the most basic shelters, eating the most basic diets, with no access to clean water or toilets and little access to health care or education, the people seemed happy. I was invited into their homes and lives, slept on their straw mats, ate their rice and drank their tea. Their spirit and sense of contentment drew me back over the years 15 times. Nepal became a sanctuary for me, a place that gave me time to reflect upon what is truly important, a place that provided energy and inspiration for me. Its public health and education needs were apparent to me, but again, I felt sympathy for my Nepali friends; I did not see that I could—and must—help.It took a chance meeting to change that. Two years ago, I was on an exploratory trek on the Great Himalayan Trail in the Kanchenjunga region of Nepal. Namgyal was our sirdar (head sherpa guide), short in stature, but a giant of a man. Lacking a formal education, but very bright and [End Page 84] motivated, he rose through the ranks from porter all the way to lead sherpa of Everest Expeditions. He had reached the summit of Everest ten times by the age of thirty. He led... (shrink)

The Sundarban forest in southern Bengal was for many centuries a frontier zone—an economic frontier for communities of wet rice farmers who brought with them technologies and forms of social organization from points further to the west; a political frontier for large centralized states expanding from North India; and a cultural frontier for the worldwide community of Muslims. This paper investigates the forces that, between the thirteenth and eighteenth centuries, lay behind the transformation of Bengal's natural forest into (...) class='Hi'>rice paddy, a transformation that was accompanied by conversion to Islam, state formation, and the evolution of new land tenures.

The landscape of the Sundarbans today is a product of two countervailing forces: conversion of wetland forests to cropland vs. sequestration of the forests in reserves to be managed for long-term sustained yield of wood products. For two centures, land-hungry peasants strove to transform the native tidal forest vegetation into an agroecosystem dominated by paddy rice and fish culture. During the colonial period, their reclamation efforts were encouraged by landlords and speculators, who were themselves encouraged by increasingly favorable state (...) policies (land grants, tax incentives, cadastral surveys, and eventually colonization projects and subsidized irrigation) designed by revenue officials to maximize the rate of transformation of wetland forest to taxable agricultural land.In the late nineteenth century, as the rate of agricultural conversion increased, the colonial Forest Department succcessfully sought to preserve large areas of the remaining Sundarbans tidal forest by giving them legal status as Reserved or Protected Forests. These forests were intensively managed to provide a sustainable supply of timber and firewood for the increasing population of southern Bengal. Institutionalization of conflicting policies by the Revenue and Forest Departments reflected the escalating needs for both food and forest products as the colony grew. Today, supplies of some economically valuable trees have been depleted, and some mammals are locally extinct (although the Bengal tiger remains), but government policy in both Bangladesh and India now favors use of the Sundarbans as forest rather than its transformation to agricultural land. Further expansion of cropland to meet the grain demands of the burgeoning Bengali population in both nations has largely taken place outside the boundaries of the Sundarbans. Overexploitation of these forests for wood products remains a possibility, but large-scale clearing for rice paddies is unlikely under present policies. (shrink)

In plants, successful sexual reproduction and the ensuing development of seeds and fruits depend on flowering at the right time. This involves coordinating flowering with the appropriate season and with the developmental history of the plant. Genetic and molecular analysis in the small cruciform weed, Arabidopsis, has revealed distinct but linked pathways that are responsible for detecting the major seasonal cues of day length and cold temperature, as well as other local environmental and internal signals. The balance of signals from (...) these pathways is integrated by a common set of genes to determine when flowering occurs. Excitingly, it has been discovered that many of these same genes regulate flowering in other plants, such as rice. This review focuses on recent advances in how three of the signalling pathways (the day‐length, vernalisation and autonomous pathways) function to control flowering.

Logic has pride of place in mathematics and its 20th century offshoot, computer science. Modern symbolic logic was developed, in part, as a way to provide a formal framework for mathematics: Frege, Peano, Whitehead and Russell, as well as Hilbert developed systems of logic to formalize mathematics. These systems were meant to serve either as themselves foundational, or at least as formal analogs of mathematical reasoning amenable to mathematical study, e.g., in Hilbert’s consistency program. Similar efforts continue, but have been (...) expanded by the development of sophisticated methods to study the properties of such systems using proof and model theory. In parallel with this evolution of logical formalisms as tools for articulating mathematical theories (broadly speaking), much progress has been made in the quest for a mechanization of logical inference and the investigation of its theoretical limits, culminating recently in the development of new foundational frameworks for mathematics with sophisticated computer-assisted proof systems. In addition, logical formalisms developed by logicians in mathematical and philosophical contexts have proved immensely useful in describing theories and systems of interest to computer scientists, and to some degree, vice versa. Three examples of the influence of logic in computer science are automated reasoning, computer verification, and type systems for programming languages. (shrink)

The proof theory of many-valued systems has not been investigated to an extent comparable to the work done on axiomatizatbility of many-valued logics. Proof theory requires appropriate formalisms, such as sequent calculus, natural deduction, and tableaux for classical (and intuitionistic) logic. One particular method for systematically obtaining calculi for all finite-valued logics was invented independently by several researchers, with slight variations in design and presentation. The main aim of this report is to develop the proof theory of finite-valued first order (...) logics in a general way, and to present some of the more important results in this area. In Systems covered are the resolution calculus, sequent calculus, tableaux, and natural deduction. This report is actually a template, from which all results can be specialized to particular logics.

This study reconstructs the relationship between philosophy and politics in the way in which Heidegger's failure as a politician influenced the redevelopment of philosophy in the 1930s. The author also explains how Heidegger's failure influenced the content and direction of his later work.

Studies the politics of Heidegger in terms of "thrownness" or "existential contingency". Attempts to think through Heidegger's philosophy in a manner that parallels his own dialogue with other key western thinkers.

The number of studies examining visual perspective during retrieval has recently grown. However, the way in which perspective has been conceptualized differs across studies. Some studies have suggested perspective is experienced as either a first-person or a third-person perspective, whereas others have suggested both perspectives can be experienced during a single retrieval attempt. This aspect of perspective was examined across three studies, which used different measurement techniques commonly used in studies of perspective. Results suggest that individuals can experience more than (...) one perspective when recalling events. Furthermore, the experience of the two perspectives correlated differentially with ratings of vividness, suggesting that the two perspectives should not be considered in opposition of one another. We also found evidence of a gender effect in the experience of perspective, with females experiencing third-person perspectives more often than males. Future studies should allow for the experience of more than one perspective during retrieval. (shrink)

Having visited Ireland regularly during the 1930s, Ludwig Wittgenstein resigned his Cambridge philosophy professorship in 1947 and moved there, living in a fishing village on the Atlantic coast and hotels in Dublin and the Wicklow Mountains. Although Wittgenstein spent some time out of the country, Ireland was effectively his base for three very productive years during which he worked on what would become one of his key books, the posthumously published Philosophical Investigations. Wittgenstein in Ireland represents the first sustained account (...) of Wittgenstein's time in Ireland, placing it in its historical context. Wall pays a good deal of attention to the representation of the Irish landscape in which the Austrian philosopher found himself able to work; a large part of his writings were produced in the bleak landscapes of Ireland and Norway.

Despite their differences in origin, the three influential schools of twentieth-century continental cultural criticism--the Frankfurt School, existentialism, and poststructuralism--have long been treated as an ensemble and with critical hesitancy. Examining these schools as responses to the apparent collapse of Western civilization in the twentieth-century and as formidable intellectual challenges to the cultural legacies of the Enlightenment, this book provides a productive base for criticism and broadens our understanding of their histories and reception.

For Ivor Grattan-Guinness on the occasion of his retirement. The work of Augustus De Morgan on symbolic logic in the mid-nineteenth century is familiar to historians of logic and mathematics alike. What is less well known is his work on probability and, more specifically, the use of probabilistic ideas and methods in his logic. The majority of De Morgan's work on probability was undertaken around 1837???1838, with his earliest publications on logic appearing from 1839, a period which culminated with the (...) publication of his Formal Logic in 1847. This article examines the overlap between his work on probability theory and logic during the earliest period of his interest in both. (shrink)

Hilbert’s program was an ambitious and wide-ranging project in the philosophy and foundations of mathematics. In order to “dispose of the foundational questions in mathematics once and for all,” Hilbert proposed a two-pronged approach in 1921: first, classical mathematics should be formalized in axiomatic systems; second, using only restricted, “finitary” means, one should give proofs of the consistency of these axiomatic systems. Although Gödel’s incompleteness theorems show that the program as originally conceived cannot be carried out, it had many partial (...) successes, and generated important advances in logical theory and metatheory, both at the time and since. The article discusses the historical background and development of Hilbert’s program, its philosophical underpinnings and consequences, and its subsequent development and influences since the 1930s.

Methods available for the axiomatization of arbitrary finite-valued logics can be applied to obtain sound and complete intelim rules for all truth-functional connectives of classical logic including the Sheffer stroke and Peirce’s arrow. The restriction to a single conclusion in standard systems of natural deduction requires the introduction of additional rules to make the resulting systems complete; these rules are nevertheless still simple and correspond straightforwardly to the classical absurdity rule. Omitting these rules results in systems for intuitionistic versions of (...) the connectives in question. (shrink)

In 1975 the exhibition New Topographics: Photographs of a Man-Altered Landscape crystallized a new view of the American West: the sublime “American” vistas of Ansel Adams were replaced and subverted by images of a landscape inundated with banal symbols of humanity. Organized by William Jenkins for the George Eastman House in Rochester, New York, New Topographics showcased such photographers as Robert Adams, Lewis Baltz, Joe Deal, Frank Gohlke. Their pictures, illustrating the vernacular, human-made world of contemporary America, punctured the myth (...) of the pristine, wild American landscape—and definitively changed the course of landscape photography. Reframing the New Topographics offers the first substantive analysis of this shift and the continuing influence of an exhibition that not only reshaped the look and subject matter of landscape photography, but also foreshadowed environmentalism’s expansion beyond the mere preservation of wilderness. The essays in this anthology will add an important new dimension to the studies of art history and visual culture. (shrink)
