In this paper, we shall discuss some recent contributions to the project [15, 14, 2, 18, 22, 23] of explaining why no satisfactory system of complete invariants has yet been found for the torsion-free abelian groups of finite rank n ≥ 2. Recall that, up to isomorphism, the torsion-free abelian groups of rank n are exactly the additive subgroups of the n-dimensional vector space ℚn which contain n linearly independent elements. Thus the collection of torsion-free abelian groups of rank at (...) most n can be naturally identified with the set S of all nontrivial additive subgroups of ℚn. In 1937, Baer [4] solved the classification problem for the class Sof rank 1 groups as follows.Let ℙ be the set of primes. If G is a torsion-free abelian group and 0 ≠ x ϵ G, then the p-height of x is defined to behx = sup{n ϵ ℕ ∣ There exists y ϵ G such that pny = x} ϵ ℕ ∪{∞}; and the characteristic χ of x is defined to be the function.

Nagel' s pessimistic conclusion that current welfare state arrangements approximate to the most pragmatically effective way of reconciling the demands of morality and of an egalitarian liberalism, while not removing a deep seated incoherence between these view, can be resisted. The objective/subjective dichotomy, in this case applied via the agent-neutral/agent-relative distinction, is identified as his problematic assumption: understood in Hegelian terms as the "placing" of different categories of reason, even a minimal realism makes it difficult to understand how embedding agent-relativity (...) alongside the agent-neutral can be understood as adding to the relevant values, just by moving from a more particular to a less particular conception of the world. This transition also cannot be seen as giving us insight into the intrinsicality of certain values, as that would be to renege on the idea that the subjective point of view is still a point of view on value and one that is expanded, not renounced. It is argued that the standard objection that contractualism is fatally circular is even more plausible in the case of its use as a theory of political legitimacy and Nagel's use of it is quite open about this circularity. Criticising Nagel's philosophical anthropology allows one to develop his positive arguments for egalitarianism; the development of civic virtue, from a perspective in which "the personal" acknowledges the demands of others in one's political community, leads to a political egalitarianism located in a distinct political morality independent of a moralised politics.

Although the traditional physician ethic sees nothing objectionable about the doctor's influence over patients, superficial conceptions of the patient's right to self-determination imply that this influence may be manipulative. On the contrary, there are several different lines of argument which can reconcile self-determination with the physician's influence. Nevertheless, drawing the boundaries between legitimate methods of persuasion, and manipulation or coercion sometimes proves difficult.

Because of the nature of preventive vaccination programs, the viability of these public health interventions is particularly susceptible to public perceptions. This is because vaccination relies on a concept of ‘herd immunity’, achievement of which requires rational public behavior that can only be obtained through full and accurate communication about risks and benefits. This paper describes how irrational behavior that threatens the effectiveness of vaccination programs – both in crisis and non-crisis situations – can be tied to public perceptions created (...) by media portrayals of health risks. I concentrate on childhood vaccination as an exemplar of ‘non-crisis’ preventive vaccination, and on the recent flu vaccine shortage as a ‘crisis’ situation. The paper concludes with an examination of the steps necessary to resolve these threats through better public communication. (shrink)

The Cratylus contains Plato's most extensive study of the relation of language to reality and to the pursuit of wisdom. Yet the dialogue has remained relatively neglected in efforts to understand Plato's deepest metaphysical and epistemological commitments. The blame for such neglect lies largely in the dialogue's extensive, difficult, even mysterious etymological section. Recent attempts to make sense of the bulk of the Cratylus are shedding much welcome light on the important roles that the etymological analyses play in the dialogue (...) and in Plato's philosophy more generally. The article outlines three strategies of interpretation before concluding with the author's own proposal. (shrink)

"The Cage of Nature" focuses on the concept of nature as a way to rethink Japanese and European versions of modernity and the historical tropes that distance "East" from "West." This essay begins by comparing Japanese political philosopher Maruyama Masao and his contemporaries, Max Horkheimer and Theodor Adorno. Both sets of authors define modernity as the moment when humanity overcomes nature, but Maruyama longs for this triumph while Horkheimer and Adorno deplore its consequences. Maruyama insists that Japan has failed to (...) attain the freedom promised by modernity because it remains in the thrall of nature defined in three ways: as Japan's deformed past, as the mark of Japan's tragic difference from "the West," and as Japan's accursed sensuality, shackling it to uncritical bodily pleasures. In short, Maruyama sees Japan as trapped in the cage of nature.My argument is that Maruyama's frustration arises from the trap set by modern historiography, which simultaneously traces the trajectory of modernity from servile Nature to freedom of Spirit and at the same time bases the identity of the non-Western world on its closeness to nature. In other words, nature represents both the past and the East, an impossible dilemma for an Asian nationalist desirous of liberty. By revising our historical narratives to take into account the ways in which Western modernity continued to engage versions of nature, it becomes possible to reposition Japan and "the East" within modernity's history rather than treating them as the Other.

Lead shot deposited in fields and woodlands near shooting rangesand intense, upland, hunting adds an enormous tonnage of lead toenvironments, worldwide. This contamination is not remedied bybanning lead shot use only for waterfowl hunting. Lead pelletsdisintegrate extremely slowly, during which time they may beingested from the soil by wild birds, livestock, or silage-makingmachinery, and cause sublethal or fatal lead poisoning. Leadpellet corrosion products contaminate soil, surface waters, andground waters, often exceeding permissible levels. Plants do notconcentrate much lead from the soil, (...) except when grown in acidicsoils of heavily-contaminated shooting ranges. Inheavily-contaminated sites, earthworms ingest leadcompounds which are bioaccumulated in higher consumersof food webs. Non-toxic substitutes made from steelor bismuth are available internationally and areeffective for all types of hunting and targetshooting. Many nations are slow to require their use,despite the marked awareness of the problems of leadshot contamination and toxicosis. This is due tohunters and international sport shooting organizationsopposing the use of non-toxic substitutes and overtemphasis by government agencies on the burden ofscientific proof for every situation, rather thantaking preventative action according to thePrecautionary Principle. The ethical approach ofDenmark and The Netherlands, which banned all uses oflead shot, is advocated as a precedent for othernations to adopt. (shrink)

We consider the results of adding to a basic modal system T0the axioms G1.CLpp;Pn.CLnpLn+1p; Bn.CpLnMp, where n ≧ 11, in all combinations. The method of Meredith's [7] will be extended to get models of these systems in lower predicate calculus (LPC) with a constant binary relation,U. Most of the results were already obtained in [1]–[6], though systems as in (i) and (ii) below were not investigated, except that S40in (ii) was mentioned in [1]. However some repetition may be excused in (...) view of the simplicity with which the results are obtained by the present method. (shrink)

This article won the Mind prize essay competition announced last year, for an essay defending the academic pursuit of philosophy. The author is at present a free-lance philosopher; at the time of writing the paper he was a part time lecturer at the University of Newcastle upon Tyne, in the department that has since closed. His collection of aphorisms, Sentences and Slogans has recently been published privately (for details, see 'Books Received').

This paper attempts to cross the disciplinary boundaries of strategic management and social issues management to demonstrate the relationship between managerial characteristics and corporate social performance (CSP). Drawing on studies in strategic leadership research we develop and test hypotheses about linkages between top management attributes and different levels of CSP. Our results add credence to the argument that organizations are a reflection of their top managers, and encourage further systematic research of the influence of key executives in developing and implementing (...) socially responsible policies and programs.

May lethal autonomous weapons systems—‘killer robots ’—be used in war? The majority of writers argue against their use, and those who have argued in favour have done so on a consequentialist basis. We defend the moral permissibility of killer robots, but on the basis of the non-aggregative structure of right assumed by Just War theory. This is necessary because the most important argument against killer robots, the responsibility trilemma proposed by Rob Sparrow, makes the same assumptions. We show that the (...) crucial moral question is not one of responsibility. Rather, it is whether the technology can satisfy the requirements of fairness in the re-distribution of risk. Not only is this possible in principle, but some killer robots will actually satisfy these requirements. An implication of our argument is that there is a public responsibility to regulate killer robots ’ design and manufacture. (shrink)

Today there is a thriving 'emotions industry' to which philosophers, psychologists and neuroscientists are contributing. Yet until two centuries ago 'the emotions' did not exist. In this path-breaking study Thomas Dixon shows how, during the nineteenth century, the emotions came into being as a distinct psychological category, replacing existing categories such as appetites, passions, sentiments and affections. By examining medieval and eighteenth-century theological psychologies and placing Charles Darwin and William James within a broader and more complex nineteenth-century setting, (...) class='Hi'>Thomas Dixon argues that this domination by one single descriptive category is not healthy. Overinclusivity of 'the emotions' hampers attempts to argue with any subtlety about the enormous range of mental states and stances of which humans are capable. This book is an important contribution to the debate about emotion and rationality which has preoccupied western thinkers throughout the eighteenth and nineteenth centuries and has implications for contemporary debates.

Thomas Hobbes (1588-1679) was an English philosopher, remembered today for his work on political philosophy. His 1651 book Leviathan established the foundation for most of Western political philosophy from the perspective of social contract theory. He also contributed to a diverse array of fields, including history, geometry, physics of gases, theology, ethics, general philosophy, and political science. He was one of the main philosophers who founded materialism. He visited Florence in 1636 and later was a regular debater in philosophic (...) groups in Paris, held together by Marin Mersenne. Hobbes's first area of study was an interest in the physical doctrine of motion and physical momentum. Despite his interest in this phenomenon, he disdained experimental work as in physics. He built a good reputation in philosophic circles and in 1645, he was chosen with Descartes, Gilles de Roberval and others, to referee the controversy between John Pell and Longomontanus over the problem of squaring the circle. His other works include: The Elements of Law Natural and Politic (1640) and De Cive (The Citizen): Philosophical Rudiments Concerning Government and Society (1651). (shrink)

The modern debate on whether—and why—physicians and hospitals can refuse patient or family demands for treatment on grounds of “futility” will be reaching its 20th anniversary this year (Blackhall, 1987). The early debate focused on the use of CPR, for good historical and clinical reasons, and CPR probably remains the primary target of hospital policy. But the reach of the arguments over futility extends well beyond this context, most vividly illustrated by the case of Helga Wanglie and the many commentaries (...) it spawned (Brody, 1998; Schneiderman, 1998; Trotter, 1999). There seems no obvious reason in principle that questions about futility cannot be raised about virtually any form of treatment that patients or families might demand, including such things as chemotherapy for cancer (Tomlinson, 2001). Still, we might fairly ask what new dimensions and complexities the futility question acquires when it moves onto decisions about treatments other than CPR. This is what I would like to do in this essay. I will use dialysis as the case in point, although I hope to extract lessons from the dialysis example that will be pertinent to other forms of life-sustaining treatment, like ventilators. (shrink)

DIVBased on a series of lectures delivered in 1840, Thomas Carlyle’s On Heroes, Hero-Worship, and the Heroic in History considers the creation of heroes and the ways they exert heroic leadership. From the divine and prophetic to the poetic to the religious to the political, Carlyle investigates the mysterious qualities that elevate humans to cultural significance. By situating the text in the context of six essays by distinguished scholars that reevaluate both Carlyle’s work and his ideas, David Sorensen and (...) Brent Kinser argue that Carlyle's concept of heroism stresses the hero’s spiritual dimension. In Carlyle’s engagement with various heroic personalities, he dislodges religiosity from religion, myth from history, and truth from “quackery” as he describes the wondrous ways in which these “flowing light-fountains” unlock the heroic potential of ordinary human beings. /div.

This essay examines the role of the University of Bridgeport's Faculty Council in relation to the faculty union. The Faculty Council is a governing body composed of elected faculty representatives from different schools and departments within the university. Faculty Council leaders facilitated the certification of AAUP as the faculty's bargaining agent in 1973 and, under the author's leadership, the faculty petitioned the National Labor Relations Board to decertify the union in 1991. The author participated on the picket line during the (...) 1975, 1978 and 1987 faculty strikes, but crossed the picket line during the 1990 strike. (shrink)

This book presents a radical and intuitive argument against the notion that intentional action, agency and autonomy are features belonging only to humans. Using evidence from research into the minds of non-human animals, it explores the ways in which animals can be understood as individuals who are aware of themselves, and the consequent basis of our moral obligations towards them. The first part of this book argues for a conception of agency in animals that admits to degrees among individuals and (...) across species. It explores self-awareness and its various levels of complexity which depend on an animals’ other mental capacities. The author offers an overview of some established theories in animal ethics including those of Peter Singer, Tom Regan, Bernard Rollin and Lori Gruen, and the ways these theories serve to extend moral consideration towards animals based on various capacities that both animals and humans have in common. The book concludes by challenging traditional Kantian notions of rationality and what it means to be an autonomous individual, and discussing the problems that still remain in the study of animal ethics.

Albert Einstein was the most influential physicist of the twentieth century. Less well-known is that fundamental philosophical problems, such as concept formation, the role of epistemology in developing and explaining the character of physical theories, and the debate between positivism and realism, played a central role in his thought as a whole. Thomas Ryckman shows that already at the beginning of his career, at a time when the twin pillars of classical physics, Newtonian mechanics and Maxwell’s electromagnetism, were known (...) to have but limited validity, Einstein sought to advance physical theory by positing certain physical principles as secure footholds. That philosophy produced his greatest triumph, the general theory of relativity, and his greatest failure, an unwillingness to accept quantum mechanics. This book shows that Einstein’s philosophy grew from a lifelong aspiration for a unified theoretical representation encompassing all physical phenomena. It also considers how Einstein’s theories of relativity and criticisms of quantum theory have shaped the course of twentieth-century philosophy of science. Including a chronology, glossary, chapter summaries, and suggestions for further reading, _Einstein_ is an ideal introduction to this iconic figure in twentieth-century science and philosophy. It is essential reading for students of philosophy of science, and also suitable for those working in related areas such as physics, history of science, or intellectual history. (shrink)
