Based on a gambling formulation of quantum mechanics, we derive a Gleason-type theorem that holds for any dimension n of a quantum system, and in particular for \. The theorem states that the only logically consistent probability assignments are exactly the ones that are definable as the trace of the product of a projector and a density matrix operator. In addition, we detail the reason why dispersion-free probabilities are actually not valid, or rational, probabilities for quantum mechanics, and hence (...) should be excluded from consideration.

The concept of Nothingness—Japanese mu or Chinese wú 無—is central both to the Kyoto School and to important strands of Chinese philosophy. The Kyoto School, which has been active since the 1930s, is arguably modern Japan’s most philosophically sophisticated challenge to Western thought. Further, as contemporary East Asia continues to rise in importance, East Asians and Westerners alike are beginning to consider anew the contemporary philosophical relevance of Confucianism, Daoism, and East-Asian Buddhism. These originally Chinese traditions were certainly important influences (...) directly and indirectly on Kyoto School philosophy itself. At the very least, Kyoto thought and Chinese thought share foundational structural resemblances, especially regarding the concept of Nothingness. This study summarizes the concept of Nothingness in the Kyoto School and in Chinese philosophy, and then offers an evaluation of the contemporary relevance and general coherence of this concept.

Heidegger and East-Asian thought have traditionally been strongly correlated. However, although still largely unrecognized, significant differences between the political and metaphysical stance of Heidegger and his perceived counterparts in East-Asia most certainly exist. One of the most dramatic discontinuities between East-Asian thought and Heidegger is revealed through an investigation of Kitarō Nishida’s own vigorous criticism of Heidegger. Ironically, more than one study of Heidegger and East-Asian thought has submitted that Nishida is that representative of East-Asian thought whose philosophy most closely (...) resembles Heideggerian thought. In words that then and now resound discordantly within the enshrined, established view of Heidegger’s relationship to East-Asian thought, Nishida stated uninhibitedly his own view of Heidegger in the noteworthy statement: “Heidegger is not worth your time… He…does not recognize that which is indispensible and decisive, namely, God.” This present study lays out for the first time in English, the significant differences between the metaphysical and political stances of Nishida and Heidegger, Nishida’s own critique of Heidegger, and Heidegger’s own rather dismal assessment of non-Western philosophy, all of which demonstrate a remarkable, hitherto unrecognized discontinuity between Heidegger and East-Asian thought.

Despite the central role that the concept of God played in Kitarō Nishida's philosophy—and more broadly, within the Kyoto School which formed around Nishida—Anglophone studies of the religious philosophy of modern Japan have not seriously considered the nature and role of God in Nishida's thought. Indeed, relevant Anglophone studies even strongly suggest that where the concept of God does appear in Nishida's writings, such a concept is to be dismissed as a 'subjective fiction', a 'penultimate designation', or a peripheral Western (...) intrusion with no genuine relationship to the core of Nishida's thought. However, a careful study of Nishida's own writings reveals that for Nishida, in his own words, God is 'that which is indispensable and decisive'. For the first time in English, this present study reveals Nishida's view of God, especially examining Nishida's debt to the theologian Karl Barth and Christianity. (shrink)

Evidence of an emerging focus on the role of farmer knowledge in developed countries is highlighted by the debate on the nature of local and scientific knowledge. Less attention has been paid to the interaction of different ways of knowing for sustainable capital-intensive agriculture. This paper explores the relationship between local and scientific knowledge in managing temperate pasture and grazing systems in Australia. The nature of farmer knowledge is firstly examined by describing the experiences of farm families in managing native (...) and introduced perennial grasses in upland areas of the Murray-Darling Basin. The building of knowledge and skills through social learning was explored in group case studies and interviews with stakeholders involved in pasture research and development. The interchange of local and scientific knowledge in groups was shown to have a synergistic effect, whereby local knowledge was broadened and strengthened, and scientific knowledge adapted and molded to specific situations. The effectiveness of social learning was greatest in collaborative programs based on small, local groups involved in monitoring and evaluation of whole farm pasture and grazing systems. (shrink)

There are over 2,500 Landcare groups with 65,000 members operating across Australia. With considerable evidence of program impact, Landcare is an important example of state sponsored community participation in natural resource management. However, the authors suggest excessive emphasis has been placed upon attitudinal change - the development of landholder stewardship, as the lever for effecting major changes in land management. Analysis of data from a landholder survey failed to establish predicted stewardship differences between Landcare and nonLandcare respondents or between those (...) who joined early/late, or participated more/less in group activities. And there was no relationship between stewardship and adoption for most of the sustainable agriculture practices surveyed. Further analysis clearly linked Landcare participation and concern about the environmental and economic impacts of land degradation. Whilst respondents were significantly more concerned about economic impacts, research findings were consistent with earlier work indicating that most land managers have a strong stewardship ethic. The authors also suggest that concerns that Landcare is not addressing biodiversity conservation are largely unjustified and reflect urealistic expectations of these voluntary groups. (shrink)

Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)

Background and objective: Code status discussions may fail to address patients’ treatment-related goals and their knowledge of cardiopulmonary resuscitation (CPR). This study aimed to investigate patients’ resuscitation preferences, knowledge of CPR and goals of care. Design, setting, patients and measurements: 135 adults were interviewed within 48 h of admission to a general medical service in an academic medical centre, querying code status preferences, knowledge about CPR and its outcome probabilities and goals of care. Medical records were reviewed for clinical information (...) and code status documentation. Results: 41 (30.4%) patients had discussed CPR with their doctor, 116 (85.9%) patients preferred full code status and 11 (8.1%) patients expressed code status preferences different from the code status documented in their medical record. When queried about seven possible goals of care, patients affirmed an average of 4.9 goals; their single most important goals were broadly distributed, ranging from being cured (n = 36; 26.7%) to being comfortable (n = 8; 5.9%). Patients’ mean estimate of survival to discharge after CPR was 60.4%. Most patients believed it was helpful to discuss goals of care (n = 95; 70.4%) and the chances of surviving inhospital CPR (n = 112; 83.0%). Some patients expressed a desire to change their code status after receiving information about survival following inhospital CPR (n = 11; 8.1%) or after discussing goals of care (n = 2; 1.5%). Conclusions: Doctors need to address patients’ knowledge about CPR and take steps to avoid discrepancies between treatment orders and patients’ preferences. Addressing CPR outcome probabilities and goals of care during code status discussions may improve patients’ knowledge and influence their preferences. (shrink)

Gleason's theorem for ������³ says that if f is a nonnegative function on the unit sphere with the property that f(x) + f(y) + f(z) is a fixed constant for each triple x, y, z of mutually orthogonal unit vectors, then f is a quadratic form. We examine the issues raised by discussions in this journal regarding the possibility of a constructive proof of Gleason's theorem in light of the recent publication of such a proof.

We prove a Gleason-type theorem for the quantum probability rule using frame functions defined on positive-operator-valued measures, as opposed to the restricted class of orthogonal projection-valued measures used in the original theorem. The advantage of this method is that it works for two-dimensional quantum systems and even for vector spaces over rational fields—settings where the standard theorem fails. Furthermore, unlike the method necessary for proving the original result, the present one is rather elementary. In the case of a qubit, (...) we investigate similar results for frame functions defined upon various restricted classes of POVMs. For the so-called trine measurements, the standard quantum probability rule is again recovered.

In this paper I wish to show that we can give a statement of a restricted form of Gleason's Theorem that is classically equivalent to the standard formulation, but that avoids the counterexample that Hellman gives in "Gleason's Theorem is not Constructively Provable".

While the preponderance of recent literature on David Gauthier's Morals by Agreement has focused on his theory of bargaining,1 Joseph DeMarco calls into question the foundation of Gauthier's project.2 DeMarco argues that Gauthier's project depends on the incorporation of extra‐rational values, thereby undermining his attempt to derive morality from the non‐moral premises of rational choice. On DeMarco's account, there are at least three points where Gauthier depends on extra‐rational values. DeMarco finds the first two of these points problematic because he (...) misunderstands Gauthier's theory of rational choice. The third point is more serious; Gauthier does not offer an apparatus sufficient to respond to DeMarco's charge. To disarm DeMarco's third objection, I shall offer a justification of the rationality of autonomous preference formation. (shrink)

A number of studies have tested the relationship between a corporation's social and ethical performance and its financial performance. In contrast, this is the first study to demonstrate a link between overall financial performance and an emphasis on ethics as an aspect of corporate governance. It identifies the 26.8 percent of the 500 largest U.S. public corporations that, in their annual report to shareholders, commit to ethical behavior toward their stakeholders or emphasize compliance with their code of conduct. The financial (...) performance of these corporations ranks higher than that of those who do not at a significance level of p = < 0.005, using the 1997 Business Week ranking which averages eight publicly-reported measures of historical financial performance. These findings should motivate more corporations to utilize the principles of Social and Ethical Accounting, Auditing and Reporting (SEAAR). (shrink)

This paper attempts a deduction of Kant's concept of the highest good: that is, it attempts to prove, in accordance with Dieter Henrich.s interpretation of the notion of deduction, that the highest good is an end that is also a duty. It does this by appealing to features of practical reason that make up the legitimating facts that serve as the premises that any deduction must possess. According to Kant, the highest good consists of happiness, virtue, and relations of proportionality (...) and causation between happiness and virtue, such that happiness is proportional to and caused by virtue. I argue, by drawing on accepted Kantian notions, that Kant had compelling reasons for concluding that the highest good is in fact an end that is also a duty. If correct, then this argument provides the deduction promisedin my title. (shrink)

It has become apparent that the debate between scientific realists and constructive empiricists has come to a stalemate. Neither view can reasonably claim to be the most rational philosophy of science, exclusively capable of making sense of all scientific activities. On one prominent analysis of the situation, whether we accept a realist or an anti-realist account of science actually seems to depend on which values we antecedently accept, rather than our commitment to “rationality” per se. Accordingly, several philosophers have attempted (...) to argue in favour of scientific realism or constructive empiricism by showing that one set of values is exclusively best, for anyone and everyone, and that the downstream choice of the philosophy of science which best serves those values is therefore best, for anyone and everyone. These efforts, however, seem to have failed. In response, I suggest that philosophers of science should suspend the effort to determine which philosophy of science is best for everyone, and instead begin investigating which philosophy of science is best for specific people, with specific values, in specific contexts. I illustrate how this might be done by briefly sketching a single case study from the history of science, which seems to show that different philosophies of science are better at motivating different forms of scientific practice.

What is the nature of time? Does it flow? Do the past and future exist? Drawing connections between historical and present-day questions, A Critical Introduction to the Metaphysics of Time provides an up-to-date guide to one of the most central and debated topics in contemporary metaphysics. Introducing the views and arguments of Parmenides, Plato, Aristotle, Descartes, Newton and Leibniz, this accessible introduction covers the history of the philosophy of time from the Pre-Socratics to the beginning of the 20th Century. The (...) historical survey presents the necessary background to understanding more recent developments, including McTaggarts 1908 argument for the unreality of time, the open future, the perdurance/endurance debate, the possibility of time travel, and the relevance of current physics to the philosophy of time. Informed by cutting-edge philosophical research, A Critical Introduction to the Metaphysics of Time evaluates influential historical arguments in the context of contemporary developments. (shrink)

Several recent commentators have suggested that for fully rational agents who find themselves in iterated prisoner's dilemmas of indefinite length, co-operation is the rational strategy. Their argument is that these fully rational agents can be taught, through the co-operative actions of other agents, to bypass the dominant move of noncooperation and co-operate instead. The proponents of the “teaching strategy” seem to have ignored the compelling argument of Jordan Howard Sobel. While the teaching argument may work for agents who are less (...) than purely rational, Sobel has pointed out that hyperrational utility maximizers cannot be taught; they reason deductively, not inductively, as the “teaching argument” requires.

Individual differences in ethical ideology are believed to play a key role in ethical decision making. Forsyths (1980) Ethics Position Questionnaire (EPQ) is designed to measure ethical ideology along two dimensions, relativism and idealism. This study extends the work of Forsyth by examining the construct validity of the EPQ. Confirmatory factor analyses conducted with independent samples indicated three factors – idealism, relativism, and veracity – account for the relationships among EPQ items. In order to provide further evidence of the instruments (...) nomological and convergent validity, correlations among the EPQ subscales, dogmatism, empathy, and individual differences in the use of moral rationales were examined. The relationship between EPQ measures of idealism and moral judgments demonstrated modest predictive validity, but the appreciably weaker influence of relativism and the emergence of a veracity factor raise questions about the utility of the EPQ typology.

Human interaction and communication involve space in multiple ways. This paper examines the spatial and interactional order of a covertly video-taped police interrogation. When the participants enter the interrogation room and become engaged in the interrogation process, the room itself is a constraint and a resource for interaction. While interacting within a built environment, the participants appropriate their material surroundings in ways that constitute a spatial order and make possible certain arguments. This paper examines how the physical structure of the (...) interrogation room is differentially appropriated, used, and filled in by the participants''; territorial and postural manoeuvers over the course of their interaction; and how the spatial structures thus created by the bodily appropriation of the physical locale are subsequently formulated by talk and thereby used as a metaphorical resource to frame the participants'' situated experience. Through this embedded process, the interrogators move the suspect toward confession. (shrink)
