Quantum interference, manifest in the two slit experiment, lies at the heart of several quantum computational speed-ups and provides a striking example of a quantum phenomenon with no classical counterpart. An intriguing feature of quantum interference arises in a variant of the standard two slit experiment, in which there are three, rather than two, slits. The interference pattern in this set-up can be written in terms of the two and one slit patterns obtained by blocking one, or more, of the (...) slits. This is in stark contrast with the standard two slit experiment, where the interference pattern cannot be written as a sum of the one slit patterns. This was first noted by Rafael Sorkin, who raised the question of why quantum theory only exhibits irreducible interference in the two slit experiment. One approach to this problem is to compare the predictions of quantum theory to those of operationally-defined ‘foil’ theories, in the hope of determining whether theories that do exhibit higher-order interference suffer from pathological—or at least undesirable—features. In this paper two proposed extensions of quantum theory are considered: the theory of Density Cubes proposed by Dakić, Paterek and Brukner, which has been shown to exhibit irreducible interference in the three slit set-up, and the Quartic Quantum Theory of Życzkowski. The theory of Density Cubes will be shown to provide an advantage over quantum theory in a certain computational task and to posses a well-defined mechanism which leads to the emergence of quantum theory—analogous to the emergence of classical physics from quantum theory via decoherence. Despite this, the axioms used to define Density Cubes will be shown to be insufficient to uniquely characterise the theory. In comparison, Quartic Quantum Theory is a well-defined theory and we demonstrate that it exhibits irreducible interference to all orders. This feature of Życzkowski’s theory is argued not to be a genuine phenomenon, but to arise from an ambiguity in the current definition of higher-order interference in operationally-defined theories. Thus, to begin to understand why quantum theory is limited to a certain kind of interference, a new definition of higher-order interference is needed that is applicable to, and makes good operational sense in, arbitrary operationally-defined theories.

edited by Ciaran Cronin and Pablo De Greiff Since its appearance in English translation in 1996, Jürgen Habermas's Between Facts and Norms has become the focus of a productive dialogue between German and Anglo-American legal and political theorists. The present volume contains ten essays that provide an overview of Habermas's political thought since the original appearance of Between Facts and Norms in 1992 and extend his model of deliberative democracy in novel ways to issues untreated in the earlier work.Habermas's (...) theory of democracy has at least three features that set it apart from competing positions. First, it combines a concern with questions of normative justification with an empirical analysis of the social conditions necessary for the realization of democratic institutions. Second, at the heart of his model is the assertion of an internal relationship between liberalism and democracy. On this account, the rights of the individual that are central to liberalism can be guaranteed only within a constitutional framework that at the same time fosters democratic rights of political participation through the public sphere. Finally, Habermas defends a conception of universal human rights that is not only sensitive to cultural differences but also calls for legal and political institutions that facilitate the cultivation of cultural and religious identities within pluralistic societies.These essays demonstrate the extraordinary power of Habermas's theory of democracy through a further engagement with Rawls's political liberalism and through original contributions to current debates over nationalism, multiculturalism, and the viability of supranational political institutions.

Philosophers and psychologists both investigate the self, but often in isolation from one another. this book brings together studies by philosophers and psychologists in an exploration of the self and its function. It will be of interest to all those involved in philosophy, psychology and sociology.

This collection of four essays and an interview contains Habermas's most recent contributions to ethical theory. It expands and clarifies the work on discourse ethics presented in Moral Consciousness and Communicative Action. Here, largely in response to criticisms from contemporary neo-Aristotelians, Habermas underscores the claim of discourse ethics to a preeminent position in contemporary moral philosophy with incisive analyses and refinements of the central concepts of his theory that include important developments in his treatment of practical reason and of the (...) problems of application and motivation.The first essay offers a comprehensive analysis of practical rationality, which establishes a clear demarcation between pragmatic, ethical, and moral questions and a corresponding differentiation between forms of volition and spheres of practical discourse. The centerpiece of the book is a multifaceted defense of the central claims of discourse ethics incorporating masterly critiques of the major competing positions, including those of John Rawls, Bernard Williams, Charles Taylor, Alasdair MacIntyre, Karl-Otto Apel, and Albrecht WellmerThe middle essays defend the basic intention of universalist moral theory in the face of the claims of the neo-Aristotelian ethics of the good and Horkheimer's skepticism toward reason that led him to embrace a religiously inspired ethic of compassion. An interview with Habermas covering such topics as the genesis of discourse ethics, the precise import of some of its more controversial elements, and its interconnections with the theory of communicative actions concludes this important collection.Jürgen Habermas is Professor of Philosophy at the University of Frankfurt.

The British Association for the Advancement of Science (BAAS), like many nineteenth-century institutions, sought to avoid controversy by excluding the discussion of political and religious topics from its proceedings. Nonpartisanship was a veneer it could hide behind. Yet during the Montreal meeting of 1884—the first time the association ventured beyond the comfortable confines of the British Isles—this “middle way” was tested. While local and visiting Anglophones, many of them BAAS members, viewed the proceedings and character of the association as “decidedly (...) friendly” to religion and as promoting the broad interests of Protestants, Montreal’s episcopacy and French- speaking press rallied against the anti-Catholic BAAS, accusing it of harboring a dangerous Masonic clique. In different material and social spaces, the relationship between science, religion, and the association was conceived in distinct ways. In examining this case, this essay seeks to augment the growing body of scholarship within science studies that recognizes the importance of writing both the history and the geography of encounters between science and religion.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.1 (2003) 51-80 [Access article in PDF] Kant's Politics of Enlightenment Ciaran Cronin THE ENDURING RESONANCE OF Kant's brief essay "An Answer to the Question: What is Enlightenment?" (henceforth "WE") can be traced in large part to the connection it makes between two ideas central to the self-understanding of European modernity. The first is the idea of autonomy implicit in its famous (...) definition of enlightenment: "Enlightenment is the human being's emergence from his self-incurred minority.Minority is the inability to make use of one's own understanding without direction from another... Sapere aude! Have courage to make use of your own understanding! is thus the motto of enlightenment." 1 Kant's rallying cry to independence of thought resonates with the view that individual autonomy is a central component of modern self-identity. The second is the defense of freedom in the public use of reason: "For this enlightenment, however, nothing is required but freedom, and indeed the least harmful of anything that could even be called freedom: namely freedom to make public use of one's reason in all matters." 2 With this emphatic endorsement of freedom of expression as a precondition of enlightenment, Kant appears to situate the project of enlightenment squarely in the tradition of liberal political thought. [End Page 51]Yet the interpretation of the essay as a defense of a liberal model of freedom of expression proves to be problematic on a closer reading. Even Kant's famous definition of enlightenment is not without its puzzling aspects. He employs the legal term "minority" (Unmündigkeit, often translated as "immaturity"), the condition of a child or dependent who has not reached the legal age of adulthood, to describe the condition of human beings before they have achieved enlightenment; but as some of his contemporaries remarked, the idea of a minority that is "self-incurred" makes no legal sense. That their puzzlement was not just a matter of injudicious terminology is shown by Kant's apparent indecision over whether the failure of individuals to make independent use of their reason is due to lack of courage on their part 3 or whether it is because they have been prevented from doing so by constraining social authorities. 4 Even more perplexing is Kant's idiosyncratic distinction between the private and public uses of reason: "by the public use of one's own reason I understand that use which someone makes of it as a scholar before the entire public of the world of readers. What I call the private use of reason is that which one may make of it in a certain civil post or office with which he is entrusted." 5 What is perplexing in this is not so much the restriction of the public use of reason to scholars addressing a public of readers as the characterization of the use of one's reason in exercising a civil or public office as "private." Moreover, liberal sensibilities cannot fail to be ruffled by the authoritarian cast of some of Kant's remarks. Most troubling is the observation that only a ruler who "hasa well-disciplined and numerous army ready to guarantee public peace" can tolerate complete freedom of public expression and that a lesser degree of civil freedom (bürgerliche Freiheit) is conducive to the fullest expansion of "a people's freedom of spirit" (or intellectual freedom, Freiheit des Geistes). 6 This would seem to lend ammunition to those who argue that Kant ultimately embraces a conservative politicalposition in contradiction to the radical implications of his own critical philosophy. 7 [End Page 52]But an examination of the historical context of the essay reveals that it is neither a clear expression of a liberal nor of a conservative position as these are conventionally understood, or so I will argue. The perplexing features of the essay become intelligible when it is seen as part of a larger project of reconciling the ideal requirements of a republican constitution with the political reality of Prussian absolutism in response to contemporary debates concerning...

Several fields contributing to psychiatric advances, such as psychology, biology, and the humanities, have not yet met to produce a cohesive and integrated picture of human function and dysfunction, strength and vulnerability, etc., despite advances in their own areas. The failure may have its roots in a disagreement on what we mean by the human person and his or her relationship with the world, for which the incommensurate language of these disciplines may be partly to blame. Turns taken by western (...) philosophy over the past 400 years may help to explain this. Language is such an important tool for psychiatrists, that examination of it may afford an insight into the reasons for divisions in the field. This paper aims to examine and compare psychologies (and hence psychiatries) derived from modern western philosophy, with similar concepts in other cultures, through the study of developments in terminology, in terms of the simplest facts about what it means to be human. Terminology used in mental health in western cultures is examined, with particular consideration of the term “self” as it has come to be used in a technical sense. Analogous terms from non-English speaking European languages, and some non-western cultures are studied. Western philosophy and psychology have evolved a meaning for the term “self” which is quite different from equivalent terms in non-western cultures. It is a moot point whether or not the development in western psychiatry of what are now technical terms to describe normal human experience has become needlessly obscure and ambiguous. It is not evident that this “new” language represents a genuine advance in understanding; it distances mental health professionals from those who are not familiar with it; and it makes transcultural dialogue difficult.

Professional Responsibility: New Horizons of Praxis addresses the manifold and complex challenges inherent in professional responsibility. Since the beginning of the 20th Century, professions have been accorded a conjoined mandate - political and moral responsibility - to serve the interests of individual's and society. The quality of professional work, how professionals understand and live out their responsibilities in practice, is a matter of pervasive concern since increasingly they have such a prominent presence in most people's lives. Until the late 1960's, (...) professionals' roles and responsibilities were rarely questioned, but such trust has since given way to collective scepticism concerning their commitment and willingness to live up to their moral and societal obligations. Abuse of power and privilege by some professionals has contributed to decline in trust by publics, the concept of 'good work' is increasingly challenged, and politicians and policy-makers have sought to regulate and hold professions to account. It is timely, therefore, to investigate critically conflicting discourses and practices on what counts as professional responsibility, to question how professionals understand and are prepared for a life of professional responsibility, and what acting with integrity and authority looks like in practice. One of the distinctive features of this book is the combination of normative and empirical dimensions that are used to dissect this question. The authors indicate from a diversity of disciplinary perspectives how professional responsibility includes particular thoughts and warranted actions yet remains multifaceted and inarticulate"-- Provided by publisher.

Review boards responsible for vetting the ethical conduct of research have been criticised for their costliness, unreliability and inappropriate standards when evaluating some non-medical research, but the basic value of mandatory ethical review has not been questioned. When the standards that review boards use to evaluate research proposals are applied to review board practices, it is clear that review boards do not respect researchers or each other, lack merit and integrity, are not just and are not beneficent. The few benefits (...) of mandatory ethical review come at a much greater, but mainly hidden, social cost. It is time that responsibility for the ethical conduct of research is clearly transferred to researchers, except possibly in that small proportion of cases where prospective research participants may be so intrinsically vulnerable that their well-being may need to be overseen.

" With this succinct formulation, Murray Bookchin launches his most ambitious work, The Ecology of Freedom.

In his new introduction to this current edition of this classic in the field originally published in 1982 (Humanities Press), Hoppe (economics, U. of Nevada, Las Vegas--as was the late author) extols Rothbard's marriage of the "value-free" science of economics with the normative enterprise of ethics and their offspring: libertarianism. Discussion areas are: natural law, a theory of liberty, the state vs. liberty, modern alternative theories of liberty, and toward a theory of strategy for liberty.

A challenging new work of cultural and political theory rethinks the concept of hegemony.

Foucault's theory of disciplinary power and Bourdieu's theory of symbolic power are among the most innovative attempts in recent social thought to come to terms with the increasingly elusive character of power in modern society. Both theories are based on cri tiques of subject-centered analyses of power and offer original accounts of modern social institutions. But Foucault's critique of the subject is so radical that it makes it impossible to identify any deter minate social location of the exercise of power (...) or of resistance to its operations. Bourdieu's theory of practice in terms of the symbolically mediated interaction between the habitus and social structure avoids these problems by connecting relations of domination both to identi fiable social agents and to the institutions of the modern state. However, Bourdieu's strategic model of social action remains too narrow to allow for the possibility of autonomous agency and an emancipatory political praxis. The theory of symbolic power must be supplemented by a normative conception of practical reason if its emancipatory potential is to be realized. Key Words: agency • habitus • modernity • power • resistance. (shrink)

This is a commentary on selected texts of Plato concerned with poetry: the Ion and relevant sections of the Republic. It is the first commentary to present these texts together in one volume, and the first in English on Republic 2 and 3 and Ion for nearly 100 years. The introduction sets Plato's views in their Greek context and outlines their influence on later aesthetic thought. An important feature of the commentary is its exploration of the ambivalence of Plato's pronouncements (...) through an analysis of his own skill as a writer. (shrink)

This chapter suggests that descriptive epidemiological studies like the Global Burden of Disease Study can usefully be divided into four tasks: describing individuals’ health states over time, assessing their health states under a range of counterfactual scenarios, summarizing the information collected, and then packaging it for presentation. The authors show that each of these tasks raises important and challenging ethical questions. They comment on some of the philosophical issues involved in measuring health states, attributing causes to health outcomes, choosing the (...) counterfactual against which to assess causes, aggregating and summarizing complex information across multiple domains, discounting, age-weighting, handling fetal deaths, measuring health inequalities, representing uncertainty, and assessing personal responsibility for health outcomes.

Kovacs argues that honorary authorship and regarding each co-author of multi-authored papers as if they were sole authors when the performance of researchers is being evaluated by their publications mean that we should require authors to identify what proportion of each publication should be attributed to each co-author. Even if such attributions could be made reliably, such a change should not be made. Contributions to authorship cannot be validly quantified, and the relative merits of different publications are also neither equal (...) nor validly quantifiable. Research administrators need to recognise that whatever criteria they adopt to evaluate the performance of researchers, researchers will find a way to game the system in order to maximise their personal benefit.

In notes to Hegel's Rechtsphilosophie lectures, written around the time of Haiti's 1825 ‘ransom’—the 150 million francs demanded by France to indemnify former slave and plantation owners—we find an uncanny remark. Hegel appears to report on a different ransom, a compensated abolition of slavery in North America that never happened, anticipating an application of the Fifth Amendment's takings clause that US legal scholarship routinely fails to mention. In view of Alan Brudner's enlistment of Hegel as the philosopher ‘uniquely’ able to (...) understand the Fifth Amendment's requirement for compensation for expropriations—a ‘constitutional essential for liberalism’—this paper explores the meaning of these passages in the historical context of the legal abolitions of Hegel's time: feudalism and slavery. The slaveholder indemnities were clearly the unjust ‘dividends’ of the colour line, but their legal foundations and developments in US thought of the nineteenth century also usefully illustrate takings law's foreclosure of political and social transformation through the securitization of value. Reading these histories and Hegel's comments alongside the critical interventions of the black radical tradition, I suggest that Hegel's curious remarks on compensated takings suggest not only a critical divergence from Brudner's understanding of ‘dialogic community’, but a crucial limitation in his field of analysis which pivoted on the denigration of black sovereignty. This paper thus suggests an understanding of US takings law through the shifting understandings of the term ‘ransom’—which for abolitionists such as Frederick Douglass signified not a resolution of slavery, but rather the threat of its perpetuation—and Douglass's elaboration of the pathology of the colour line.

Large mining projects can generate highly inequitable outcomes, with affected communities bearing the burden of social and environmental costs while economic benefits accrue largely to domestic and foreign metropolitan centres. This raises important ethical and social justice issues, as does the finite nature of mineral resources, which can mean that current generations enjoy the benefits of mining while future generations bear the costs of environmental and social impacts that can continue long after mining ends. During recent decades two broad approaches, (...) voluntary industry initiatives and government regulation, have been employed in attempts to achieve a more equitable distribution of mining’s positive and negative effects. Both have serious drawbacks. Industry initiatives are ultimately voluntary and may be abandoned in tough economic times; they can be highly variable across companies and projects; and they suffer from serious compliance issues. Public regulation can be inflexible, is subject to industry capture, and in many major mineral producing nations a ‘retreat from regulation’ is reducing its relevance. This article considers whether, and under what conditions, a third and emergent instrument, community development agreements, can help overcome the shortcomings associated with industry initiatives and public regulation. It argues that CDAs have considerable potential in this regard, but that communities can encounter significant practical challenges in their negotiation and implementation. In addition, disparities in negotiation power between communities and project developers can result in inequitable agreements, indicating a continued need for government involvement to create a more level ‘negotiation terrain’.

Essays exploring the prospects for transnational democracy in a world of increasing globalization.

This paper explores a novel philosophy of ethical care in the face of burgeoning biomedical technologies. I respond to a serious challenge facing traditional bioethics with its roots in analytic philosophy. The hallmarks of these traditional approaches are reason and autonomy, founded on a belief in the liberal humanist subject. In recent years, however, there have been mounting challenges to this view of human subjectivity, emerging from poststructuralist critiques, such as Michel Foucault's, but increasingly also as a result of advances (...) in biotechnology itself. In the face of these developments, I argue that the theoretical relevance and practical application of mainstream bioethics is increasingly under strain. Traditionalists will undoubtedly resist. Together, professional philosopher-bioethicists, public health policymakers, and the global commercial healthcare industry tend to respond conservatively by shoring up the liberal humanist subject as the foundation for medical ethics and consumer decision-making, appealing to the familiar tropes of reason, autonomy, and freedom.
