The debate over compensation packages for top executives is discussed. Particular emphasis is placed on the decoupling of CEO pay and organizational performance. A contrast is drawn between firms that are owner-controlled and those that are manager-controlled. Owner-controlled firms tend to be more market-driven. In manager-controlled firms, however, ownership can become diluted to the point where decisions may not always be in the best interest of shareholders. The process of determining CEO compensation packages is examined, and special attention is given (...) to the handling of stock options. In order to stem the threat of increased government intervention, suggestions are made for increasing the leverage of compensation committees and of shareholders in general. (shrink)

This comparative field study evaluated the moral reasoning used by U.S. and Belizean business students in resolving business-related moral dilemmas. The Belizeans, citizens of a less-developed country with Western heritage and a values-based education system, revolved the dilemmas using higher stages of moral judgment than did the U.S. business students.

The Academy of Management formally adopted a Code of Ethical Conduct in 1990. During the subsequent 15 years, almost nothing had been published about it and its value as a formal document meant to guide professional practice. Rather surprisingly then, in December 2005 an entirely new Code of Ethics was introduced by the Academy’s Board, to take effect in February 2006. Why was a new code promulgated? More broadly, what do the contents of these codes, the processes of their promulgation, (...) and their expressed purposes, suggest about the value of such codes for similarly situated professional associations, in general? This article seeks to identify key strengths and weaknesses of the original code, begin an assessment of the potential value of the new code, and so stimulate debate. Further, not only is this a call to the members of the Academy to engage in some thoughtful debate and possible amendment of its new code, but also a caution to all such associations to take seriously the hurdles that must be jumped before any code can be developed and promulgated to worthwhile effect.

Responding to volatile criticisms frequently leveled at Leo Strauss and those he influenced, the prominent contributors to this volume demonstrate the profound influence that Strauss and his students have exerted on American liberal democracy and contemporary political thought. By stressing the enduring vitality of classic books and by articulating the theoretical and practical flaws of relativism and historicism, the contributors argue that Strauss and the Straussians have identified fundamental crises of modernity and liberal democracy.

The article examines Jonathan Spence's book The Question of Hu, asking the central question as to what difference it makes if the book is viewed as history or fiction. In addition to raising specific questions as to Spence's treatment of his materials, the article addresses the question of the historical novel, following on the work of Georg Lukács and Sir Walter Scott, and concludes that Spence's work is not of this genre. Neither is it a history à la Herodotus or (...) Thucydides, where analysis--the raising of historical questions and sharing the evidence and inference with the reader--and narrative must go together. The article concludes that, wonderful as is The Question of Hu as literature, it is not a true piece of historical narrative. In coming to this judgment, the article has used Spence's book as a way of reflecting on fundamental questions concerning the nature of history, fiction, analysis, and narrative. (shrink)

Immanuel Kant might have stated the central and urgent problem facing contemporary literary theory as the need to seek a path between dogmatism and skepticism. We confront today a multiplicity of critical methods, each filling books and journals with no doubt convincing arguments for its correctness. If we cling to one, denying others possess truth, we are dogmatists; if, however, we grant that two or three or all are equally true, we admit that each is at the same time false (...) in relation to the others’ truth, and so we are skeptics. The “dogmatic employment” of reason, Kant noted, “lands us in dogmatic assertions to which other assertions, equally specious, can always be opposed-that is, in scepticism.”1Into this professional breach steps “pluralism” , claiming it can vindicate sharply limited patterns of reading which nonetheless allow for diversity in the relation of word to idea and, so, of interpreting reader to text. This would make it possible to encompass within a single theory the insights which both camps find in their positions. Clearly, this entices.But do we really understand what pluralism is, if it is at all? Its critical practice already exists—this essay grew from a 1984 conference which sought possible intellectual “foundations” of that practice—but how are these practitioners to understand what they do? Pluralism’s philosophic pedigree may have been neatly sketched by Nelson Goodman as the traditionThat began when Kant exchanged the structure of the world for the structure of the mind, continued when C. I. Lewis exchanged the structure of the mind for the structure of concepts, and that now proceeds to exchange the structure of concepts for the structure of the several symbols systems of the sciences, philosophy, the arts, perception, and everyday discourse. The movement is from unique truth and a world fixed and found to a diversity of right and even conflicting versions of world in the making.2 1. Immanuel Kant, Critique of Pure Reason, trans. Norman Kemp Smith , p. 57; all further references to this work, abbreviated CPR, will be included in the text.2. Nelson Goodman, Ways of Worldmaking , p. x. Since Lewis is not often classified among pluralists, I support Goodman by calling attention to Pepper having been Lewis’ student and to Lewis’ observation that he and Pepper “have been, so to say, continuously aware of each other, and of a common background of thought…. I should like to think that our respective views, both in theory of value and in ethics, are mutually supplementary rather than rival theories” . Numerous essays from this volume are useful for situating Lewis.

On 15 October 1959, Rudolf Carnap, a leading member of the recently founded Vienna Circle, came to lecture at the Bauhaus in Dessau, southwest of Berlin. Carnap had just finished his magnum opus, The Logical Construction of the World, a book that immediately became the bible of the new antiphilosophy announced by the logical positivists. From a small group in Vienna, the movement soon expanded to include an international following, and in the sixty years since has exerted a powerful sway (...) over the conduct of the philosophy of science as well as over wide branches of philosophy, economics, psychology, and physics. The site of Carnap’s lecture that day, the Dessau Bauhaus, was a stunning building designed by Walter Gropius and dedicated just three years earlier. Protected by its flat roof and glass walls, the artists, architects, weavers, and furniture designers had made the school a citadel of high modernism. It was here that Carnap addressed an enthusiastic audience on “Science and Life.” “I work in science,” he began, “and you in visible forms; the two are only different sides of a single life.”1 In this paper I will explore this “single life” of which the new philosophy and the new art were to be different facets; in the process, I hope to cast light on the shared modernist impulses that drove both disciplines in the interwar years. 1.

This newly translated Fear and Trembling, a founding document of modern philosophy and existentialism, could not be more apt for these perilous times. First published in 1843 under the pseudonym "Johannes de silentio", Søren Kierkegaard's richly resonant Fear and Trembling has for generations stood as a pivotal text in the history of moral philosophy, inspiring such artistic and philosophical luminaries as Edvard Munch, W. H. Auden, Walter Benjamin, and existentialist Jean-Paul Sartre. Retelling the biblical story of the binding of Isaac, (...) Kierkegaard expounds on the ordeal of Abraham, who was commanded to sacrifice his son in an exceptional test of faith. Disgusted at the self-certainty of his own age, Kierkegaard investigates the paradox underlying Abraham's decision to allow his duty to God to take precedence over his duties to his family. Now, in a new era of immense uncertainty and dislocation, renowned Kierkegaard scholar Bruce H. Kirmmse, in his accessible translation and engaging introduction, eloquently brings this classic work to a new generation of readers, demonstrating Kierkegaard's enduring power to illuminate the terrible wonder of faith.

Called “the most important critic of his time” by Hannah Arendt, Walter Benjamin has only become more influential over the years, as his work has assumed a crucial place in current debates over the interactions of art, culture, and meaning. A “natural and extraordinary talent for letter writing was one of the most captivating facets of his nature,” writes Gershom Scholem in his Foreword to this volume; and Benjamin's correspondence reveals the evolution of some of his most powerful ideas, while (...) also offering an intimate picture of Benjamin himself and the times in which he lived. Writing at length to Scholem and Theodor Adorno, and exchanging letters with Rainer Maria Rilke, Hannah Arendt, Max Brod, and Bertolt Brecht, Benjamin elaborates on his ideas about metaphor and language. He reflects on literary figures from Kafka to Karl Kraus, and expounds his personal attitudes toward such subjects as Marxism and French national character. Providing an indispensable tool for any scholar wrestling with Benjamin’s work, The Correspondence of Walter Benjamin, 1910–1940 is a revelatory look at the man behind much of the twentieth century’s most significant criticism.

I hope to persuade Charles Fried to think again about his developing views on distributive justice. Since I live at a certain remove from Cambridge, the best I can offer is a hypothetical dialogue with an imaginary person whose views seem, to me at least, of a Friedian inspiration. My central question deals with the way Fried establishes his rights to things he candidly concedes he does not deserve. To present my problems, I shall begin with a simpler case than (...) those – involving kidneys and talents – that Fried makes central to his discussion. Rather than starting with these rather special goods, I find it clarifying to focus first on more garden variety commodities – which, to emphasize their character, I shall call apples. (shrink)

The essays compiled in this book explore aspects of Walter Benjamin's discourse that have contributed to the formation of contemporary architectural theories. Issues such as technology and history have been considered central to the very modernity of architecture, but Benjamin's reflection on these subjects has elevated the discussion to a critical level. The contributors in this book consider Walter Benjamin's ideas in the context of digitalization of architecture where it is the very technique itself that determines the processes of design (...) and the final form. This book was published as a special issue of Architectural Theory Review. (shrink)

The subject of Stefan Collini's Absent Minds is a “rich tradition of debate about the question of intellectuals” in twentieth-century Britain, in particular debate about “their absence or comparative insignificance”. The debate begins with the Dreyfus Affair and its unpredictable British reception, simmers intriguingly through the 1920s and 1930s, and becomes positively effervescent in the 1950s, perhaps because of a new democratization of the public sphere. Collini is less interested in the possible historical causes than in the rhetorical structure that (...) persists, swirling around figures as different as T. S. Eliot, R. G. Collingwood, George Orwell, A. J. P. Taylor, and A. J. Ayer, each of whom gets a full-length profile. Other chapters mix shorter profiles—for example, the devastatingly funny discussion of Colin Wilson and the authorities who briefly and embarrassingly made him a star in their firmament—with synthesis of the debate over intellectuals at different scales and in different national settings. Coming closer to the present, Collini admires Edward Said for what he did as an intellectual while disputing what he said about intellectuals—a celebration of rigorous exile from all social belonging, which could only leave the category of the intellectual looking almost totally uninhabited. The move turns out to be characteristic: it is as if Collini felt he could win a proper admiration for what intellectuals do only by rejecting most of their self-images, or evasion thereof. (shrink)

In a recent article in Religious Studies, Professor P. W. Gooch attempts to wean the orthodox Christian from anthropological materialism by consideration of the question of the nature of the post-mortem person in the resurrection. He argues that the view that the resurrected person is a psychophysical organism who is in some physical sense the same as the ante-mortem person is inconsistent with the Pauline view of the resurrected body; rather, according to him, Paul's view is most consistent with that (...) which affirms the disembodied survival of the person. ‘I want to argue’, he writes, ‘for the thesis that a Pauline resurrection body may well be ontologically the same as a disembodied person.’ I intend to show that Professor Gooch has failed to provide any support for this view and indeed that his own view falls prey to the criticisms which he has raised against other views.

Bruce Janz, Jessica Locke, and Cynthia Willett interact in this exchange with different aspects of Chakravarthi Ram-Prasad’s book Human Being, Bodily Being. Through “constructive inter-cultural thinking”, they seek to engage with Ram-Prasad’s “lower-case p” phenomenology, which exemplifies “how to think otherwise about the nature and role of bodiliness in human experience”. This exchange, which includes Ram-Prasad’s reply to their interventions, pushes the reader to reflect more about different aspects of bodiliness.

[opening paragraph]: Walter Freeman discusses with Jean Burns some of the issues relating to consciousness in his recent book. Burns: To understand consciousness we need know its relationship to the brain, and to do that we need to know how the brain processes information. A lot of people think of brain processing in terms of individual neurons, and you're saying that brain processing should be understood in terms of dynamical states of populations?

John Stuart Mill's connection with the Irish question spanned more than four decades and embraced a variety of elements. Of his writings on Ireland, the best known are his forty-three Morning Chronicle articles of 1846–47 composed in response to the Famine, the section of the Principles of Political Economy that treats the issue of cottier tenancy and the problem of Irish land, and, most conspicuous of all, his radical pamphlet England and Ireland, published in 1868. All of these writings take (...) the land question as their paramount concern. The fairly absorbing interest in the subject disclosed by Mill during the second half of the 1840s arose from the fortuitous conjuncture of the disaster unfolding in Ireland and his engagement with the principles of political economy. Between 1848 and 1871 Mill's Principles went through seven editions and the substantive revisions he made in the section on Ireland from one edition to the next illumine both the essence and the accidentals of his bearing towards that country. Mill's cogent and controversial advocacy of fixity of tenure in England and Ireland constituted the heart of his answer to the Fenian challenge. The land question aside, Mill was drawn into the battle over the Irish university system in the 1860s largely through his friendship with John Elliot Cairnes, professor of jurisprudence and political economy at the Queen's College Galway. On this subject, however, Mill wrote almost nothing for publication. The longest single piece he ever drafted on Ireland was his first, an essay that predated the Morning Chronicle articles by two decades. In his own bibliography this essay is referred to as ‘An article on the Catholic Question which appeared in the Parliamentary Review for 1825’. Although the essay of 1825 could justly have borne the same title as the pamphlet of 1868, the particulars of course differ markedly. Ireland never ceased to pose a question during the course of the nineteenth century, but the dynamics shaping that question changed much between the mid-1820s and the late 1860s. Even so, the 1825 essay prefigures something of Mill's later involvement with the Irish question, and also invites examination as a quite remarkable piece of political journalism from the pen of a young man not yet twenty, who would subsequently establish himself as the most influential thinker of his generation.

In an attempt to make the idea of surviving one's own death in a disembodied state intelligible, H. H. Price has presented a possible description of what the afterlife might be like for a disembodied self or consciousness. Price suggests that the world of the disembodied self might be a kind of dream or image world. In it he would replace his present sense-perception by activating his image-producing powers, which are now inhibited by their continuous bombardment by sensory stimuli, to (...) produce mental images. Though he would be cut off from any new supply of sensory material, he might be able to draw upon his memory of his previous physical existence to create an entire environment of images. A nexus of perspectively inter-related images would constitute an object; this would serve as a substitute for the material objects which he perceived in his past life. The entire environment of the disembodied individual would be composed of such families of mental images and would serve to constitute his world. It need not, however, be a solipsistic world, for by means of telepathy the discarnate individual could communicate with other disembodied selves and in this way acquire new information. Price notes that since this world would be as real to the discarnate self as our present world is to our embodied self, in the afterlife the disembodied self in effect would create for itself a real world, though of course if it took it to be anything other than an image world it would be deceiving itself.

I respond to Jonathan Chimakonam’s paper in which he presents an approach to dialogue in philosophical space, and raises questions about my own approach. I raise four questions to his understanding of conversation. First, I ask him for more details on his conception of conversation. Second, what happens if not everyone cares to enter into conversation? Third, is conversation a prerequisite to philosophy, or a part of philosophy? And fourth, how does wonder fit into conversation in and about place?
