The perturbative approach to quantum field theory has long been viewed with suspicion by philosophers of science. This article offers a diagnosis of its conceptual problems. Drawing on Norton’s discussion of the notion of approximation I argue that perturbative QFT ought to be understood as producing approximations without specifying an underlying QFT model. This analysis leads to a reassessment of common worries about perturbative QFT. What ends up being the key issue with the approach on this picture is not mathematical (...) rigour, or the threat of inconsistency, but the need for a physical explanation of its empirical success. 1Three Worries about Perturbative Quantum Field Theory2The Perturbative Formalism 2.1Expanding the S-matrix2.2Perturbative renormalization3Approximations and Models4Perturbative Quantum Field Theory Produces Approximations5The Real Problem.

Recent debate in metaethics over evolutionary debunking arguments against morality has shown a tendency to abstract away from relevant empirical detail. Here, I engage the debate about Darwinian debunking of morality with relevant empirical issues. I present four conditions that must be met in order for it to be reasonable to expect an evolved cognitive faculty to be reliable: the environment, information, error, and tracking conditions. I then argue that these conditions are not met in the case of our evolved (...) faculty for moral judgement. (shrink)

Providing a precise statement of their position has long been a central challenge facing the scientific realist. This paper draws some morals about how realism ought to be formulated from the renormalization group framework in high energy physics.

In this article, we offer a detailed study of two important episodes in the early history of high-energy physics, namely the development of the Chew and the Nambu-Jona-Lasinio models. Our study reveals that both models resulted from the combination of an old Hamiltonian, which had been introduced by earlier researchers, and two new approximation methods developed by Chew and by Nambu and Jona-Lasinio. These new approximation methods, furthermore, were the key component behind the models’ success. We take this historical investigation (...) to support two philosophical theses about the manner in which scientific modelling operates in high-energy physics. Both of these theses run counter to a view that is commonly accepted among philosophers of science: the view that all approximations can be embedded within an equivalent idealized system, and that whatever role the former might play in scientific modelling is therefore parasitic on the much more substantial work performed by the latter. Our first thesis, which we call “Distinctness,” states that approximation methods constitute an independent category of theoretical output from idealized systems. We thus believe that approximations and idealized systems constitute two independent types of objects, both of which are essential to the practice of modelling. Our second, more radical thesis is called “Content Determination.” Our claim here is that approximation methods can in fact be essential to assigning determinate physical content to the idealized systems with which they jointly operate. As we show, this is due to the fact that quantum field theory allows for a very thin characterization of idealized systems only, making the use of approximations necessary to supply additional content. We conclude the paper with a few reflections about the manner in which our two theses can be used to articulate David Kaiser’s views on the “vanishing of scientific theory” in physics after WWII.

Adaptationist accounts of morality attempt to explain the evolution of morality in terms of the selective advantage that judging in moral terms secured for our ancestors (e.g. Ruse 1998; Joyce 2006; Street 2006). So-called by-product explanations of morality have been presented as an alternative to adaptationist accounts (e.g. Prinz 2009; Ayala 2010; cf. Darwin 2004/1871). In assessing the relationship between adaptationist and by-product accounts, care must be taken to distinguish several related but importantly different notions: innateness, adaptation, exaptation, spandrel, and (...) by-product.

Physicists use different theories to describe the world on different scales. In particular, they use the standard model of particle physics at very high energies, but move to various effective field theories, such as quantum electrodynamics, when modelling lower energy scattering processes. One way to explain this methodological fact is pragmatic in spirit. According to this view, physicists move to an effective field theory at lower energies in order to extract predictions and qualitative understanding which would be difficult or impossible (...) to extract directly from a more fundamental theory. By contrast, another way of accounting for the methodological data is metaphysical in spirit. On this view, the reason that physicists use different theories at different scales is that the world actually exhibits different nomic structure on different scales. These two positions have recently been thrown into sharp relief in a debate between Woodward (2016) and Batterman (2021), with Woodward taking the pragmatist line and Batterman the metaphysical line. One difficulty with the metaphysical answer is that its content is unclear: in what sense exactly could an effective field theory provide a better representation of the nomic structure of the world in its domain of applicability than our world’s fundamental theory? This talk attempts to provide an answer to this question by developing a simple metaphysical model. I start by assuming a set of possible worlds which are nomically possible according to some fundamental theory (I suggest that one is free to adopt either a Humean or Non-Humean view of these fundamental nomic necessities). I then introduce an equivalence relation between possible worlds: two worlds are scale-E equivalent if they assign the same values to physical quantities below energy scale E (up to some finite level of precision P). The key question now is whether this relation induces equivalence classes on the set of nomically possible worlds. I argue that in the case of current quantum field theories this does indeed occur, as evidenced by the possibility of “integrating out” high energy degrees of freedom in the renormalisation group framework. The formation of equivalence classes in the fundamental theory's possibility space indicates that some of its high energy features do not make a difference to its low energy dynamical behaviour. This suggests the following reading of the claim that an effective field theory provides a better representation of the nomic structure of the world in its domain of applicability: the solutions of the effective field theory stand in one-to-one correspondence with equivalence classes induced by the scale-E equivalence relation, whereas the fundamental theory overcounts the physical possibilities which are relevant at scale E. In this sense, the effective field theory provides a more natural representation of low energy physics than the fundamental theory. I conclude by explaining how this metaphysical model offers a reduction compatible understanding of multiple realisability, once again pointing to renormalisation group results in quantum field theory to support this.

The orthodox characterization of spontaneous symmetry breaking in statistical mechanics appeals to novel properties of systems with infinite degrees of freedom, namely, the existence of multiple equilibrium states. This raises the same puzzles about the status of the thermodynamic limit fueling recent debates about phase transitions. I argue that there are prospects of explaining the success of the standard approach to SSB in terms of the properties of large finite systems. Consequently, despite initial appearances, the need to account for SSB (...) phenomena does not offer decisive support to claims about the explanatory and representational indispensability of the thermodynamic limit.

Decisions about long-term ventilation in children can be clinically contentious and ethically challenging. In this article, the relevant legal, professional and moral principles inherent in such cases are explored. We commend the central importance of deliberation in the assessment of best interests, and propose a practical framework to assist the parent–clinical team to reach decisions in as transparent and equitable a manner as possible.

"Mentoring the Mentor" recreates a Freirian dialogue in a printed format. In this volume, sixteen distinguished scholars engage in a critical and thoughtful exchange with Paulo Freire. While some contributors voice appreciation for Freire's ideas and for what it means to -reinvent Freire- in a North American context, others offer sharp critiques of Freire's philosophy and, of equal importance, of the various interpretations of his work. A variety of chapters describe specific uses which have been made of Freire's ideas in (...) diverse educational contexts, from the New York City public schools to the revolutions in Guinea Bissau and Eritrea. Finally, Paulo Freire himself responds to the major issues which are raised in the volume and invites readers to share in a continuing lively dialogue about the meaning of democratic and revolutionary education. -The fundamental task of the mentor is a liberatory task. It is not to encourage the mentor's goals and aspirations and dreams to be reproduced in the mentees, the students, but to give rise to the possibility that the students become the owners of their own history. This is how I understand the need that teachers have to transcend their merely instructive task and to assume the ethical posture of a mentor who truly believes in the total autonomy, freedom, and development of those he or she mentors.- (from Chapter Sixteen, -A Response- by Paulo Freire)".

Democratic deliberation places the burden of self‐governance on its citizens to provide mutual justifying reasons (Gutmann & Thompson, 1996). This article concerns the limiting effect that group identity has on the efficacy of democratic deliberation for equality in education. Under conditions of a powerful majority, deliberation can be repressive and discriminatory. Issues of white flight and race‐based admissions serve to illustrate the bias of which deliberation is capable when it fails to substantively take group identity into account. As forms of (...) Gilbert's (1994) plural subjects, identity group members holding the group identity can experience agency as the freedom to believe together with members of their group. I argue that attending to how group members acquire group beliefs through trust is a reasonable accommodation of group identity in deliberation. (shrink)

This article is devoted to examining theoretical issues on the interface of the psychology of religion and the psychology of emotion, something which recently has been surprisingly neglected. The broad range of psychological components involved in emotion, and the importance of emotional processes in religion, make it a particularly relevant area of general psychology as far as religion is concerned. The first issue to be examined is the centrality of emotion (or feeling) in religion and the extent to which religion (...) can be conceptualized as a kind of emotional state—an idea that can be found in different forms in Schleiermacher and James. Though both psychology and emotion are now seen as less private than previously supposed, the analogy remains potentially fruitful. The second issue arises from the notable tendency in the psychology of emotion to see emotion as functional, even rational, rather than disruptive. The view of Averill is endorsed that emotions can be psychologically creative when used appropriately. This leads to a review of attitudes toward emotional aspects of religion and religious attitudes to everyday emotions, where a positive but discriminating approach to emotions seems appropriate.

In this article I reply to four critics. Responding to Linda Alcoff, I contend that my original two-dimensional framework discloses the entwinement of economic and cultural strands of subordination, while also illuminating the dangers of identity politics. Responding to James Bohman, I maintain that, with the addition of the third dimension of representation, my approach illuminates the structural exclusion of the global poor, the relation between justice and democracy, and the status of comprehensive theorizing. Responding to Nikolas Kompridis, I (...) defend a view of recognition that prioritizes the critique of institutionalized injustice. Responding to Rainer Forst, I argue that such a critique is better formulated in participation-theoretic than justification-theoretic terms. (shrink)

Three accounts of effective realism (ER) have been advanced to solve three problems for scientific realism: Fraser and Vickers (forthcoming) develop a version of ER about non-relativistic quantum mechanics that they argue is compatible with all the main realist versions (‘interpretations’) of quantum mechanics avoiding the problem of underdetermination among them; Williams (2019) and Fraser (2020b) propose ER about quantum field theory as a response to the problems facing realist interpretations; Robertson and Wilson (forthcoming) propose ER to deal (...) with the dubious ontological status of the entities belonging to superseded theories. This paper argues for the unification of these proposals based on realism about modal structure and the idea of scale relativity of ontology developed by ontic structural realists. This solves problems some or all the accounts of ER face, especially that of making explicit in what way they are realist. Furthermore, we respond to a recent critique that has been raised against the ontic structural realist account of quantum mechanics that we employ. (shrink)

In discussions about whether the Principle of the Identity of Indiscernibles is compatible with structuralist ontologies of mathematics, it is usually assumed that individual objects are subject to criteria of identity which somehow account for the identity of the individuals. Much of this debate concerns structures that admit of non-trivial automorphisms. We consider cases from graph theory that violate even weak formulations of PII. We argue that (i) the identity or difference of places in a structure is not to be (...) accounted for by anything other than the structure itself and that (ii) mathematical practice provides evidence for this view. We want to thank Leon Horsten, Jeff Ketland, Øystein Linnebo, John Mayberry, Richard Pettigrew, and Philip Welch for valuable comments on drafts of this paper. We are especially grateful to Fraser MacBride for correcting our interpretation of two of his papers and for other helpful comments. CiteULike Connotea Del.icio.us What's this? (shrink)

This article argues that a theory of recognition cannot provide the comprehensive basis for a critical theory or a conception of social justice. In this respect, I agree with Fraser's impulse to include more in such a theory, such as distributive justice and participatory parity. Fraser does not go far enough, to the extent that methodologically she seeks a theory of the same sort as Honneth's. Both Honneth's and Fraser's comprehensive theories cannot account for a central phenomenon (...) of contemporary societies: domination as structural exclusion rather than tyranny or the lack of parity. This phenomenon shows that at the very least freedom ought to remain central to any critical theory of globalization. Most of all, both theories fail to provide a way to decide whether democratic practices can produce justice. A pluralist and pragmatic form of critical theory is thus superior to any comprehensive normative theory. (shrink)

This essay is my review of Colleen Dyble’s book, Taming Leviathan: Waging a War of Ideas around the World. Dyble is affiliated with the legendary classical liberal British think tank, the Institute of Economic Affairs. Her anthology is a collection of essays by people around the world who have been involved with similar free-market think tanks in countries with historically statist economic systems. These writers include Greg Lindsay, founder of the Center for Independent Studies in Australia; Margaret Tse, of the (...) Instituto Liberdade in Brazil; Michael Walker, co-founder of the Fraser Institute in Canada; Cristian Larroulet, of Libertad y Desarrollo in Chile; Giancarlo Ibarguen, of the Center for Economic and Social Studies in Guatemala (which actually founded a free-market-oriented university); Parth Shah, founder of the Center for Civil Society in India; Daniel Doron, co-founder of the Israeli Center for Social and Economic Progress; Alberto Mingardi, of the Instituto Bruno Leoni in Italy; Masaru Uchigama, founder of the Japanese for Tax Reform; Elena Leontjeva, co-founder of the Lithuanian Free Market Institute; Alexander Magno, co-founder of the Foundation for Economic Freedom in the Philippines; and last, Leon Louw, of the Free Market Foundation of South Africa. I then discuss seven important reasons why classical liberal think tanks are so important in modern societies. (shrink)

This article is a critical examination of Nancy Fraser's contrast of early second-wave feminism and contemporary global feminism in “Feminism, Capitalism and the Cunning of History,” (Fraser ). Fraser contrasts emancipatory early second-wave feminism, strongly critical of capitalism, with feminism in the age of neoliberalism as being in a “dangerous liaison” with neoliberalism. I argue that Fraser's historical account of 1970s mainstream second-wave feminism is inaccurate, that it was not generally anti-capitalist, critical of the welfare system, (...) or challenging the priority of paid labor. I claim Fraser mistakenly takes a minority feminist position as mainstream. I further argue that Fraser's account of feminism today echoes arguments from James Petras and Henry Veltmeyer (2001) to Hester Eisenstein (), but such arguments ignore contemporary feminist minority positions. I challenge Fraser's arguments that feminism legitimates neoliberalism to women, that women's NGOs are simply service-providers enabling the state to withdraw services, and that criticisms of microcredit lending programs can be generalized into criticisms of women's feminism and women's NGOs today. I argue that these claims are vast over-generalizations and ignore countertrends. I give empirical evidence to support my objections by considering women's activities in post-communist European countries, which Fraser discusses. (shrink)

This article considers key differences and similarities between Freirean and Taoist ideals. I limit my focus to the Tao Te Ching (attributed to Lao Tzu), paying brief attention to the origins of this classic work of Chinese philosophy before concentrating on several themes of relevance to Freire's work. An essay by James Fraser (1997), who makes three references to the Tao Te Ching in his discussion of love and history in Freire's pedagogy, provides a helpful starting point for (...) investigation. A summary of Fraser's account is followed by a more detailed discussion of the meaning of ‘action’ and ‘non‐action’, the nature and role of knowing and knowledge, and the relations between ignorance, happiness and education for Freire and Lao Tzu. I conclude that while the differences between these two systems of thought are significant and must be acknowledged, reflection upon these differences has the potential to be educationally productive.

A recent book about Agricola's conquest of Scotland presents a Scottish historian's take on a subject that has been dominated by archaeologists: the whereabouts of Mons Graupius, the scene of Agricola's final battle. Unfortunately, in confidently locating it in Perthshire, author James Fraser builds his case on shaky foundations.

Nearly four decades after David Raynor attributed to David Hume an allegorical Scots militia pamphlet from the early 1760s popularly known as Sister Peg, there is still no scholarly consensus about whether the author was in fact Hume or his friend Adam Ferguson. Using new evidence that has emerged since the appearance of Raynor’s edition in 1982 – including information about Sister Peg’s publication history, Ferguson’s handwritten corrections and revisions in the Abbotsford copy of the work, a 1767 newspaper article (...) by James Boswell and a copy of a 1775 letter by Sir John Dalrymple that both named Ferguson as the author, two volumes of Ferguson’s correspondence published in 1995, and a recently discovered letter by Ferguson from 1809 – this article seeks to resolve this controversy by establishing that Sister Peg was written by Ferguson, as his fellow militia agitator Alexander Carlyle asserted in his memoirs. In the process, the article refutes Raynor’s arguments about Ferguson’s supposed incapacity for writing a satirical pamphlet like Sister Peg and clarifies the nature of Hume’s views and actions in regard to the Scots militia cause during the Seven Years’ War. The article also throws light on several related issues affecting Hume and Ferguson’s circle. (shrink)

For much of the twentieth century, philosophy and science went their separate ways. In moral philosophy, fear of the so-called naturalistic fallacy kept moral philosophers from incorporating developments in biology and psychology. Since the 1990s, however, many philosophers have drawn on recent advances in cognitive psychology, brain science, and evolutionary psychology to inform their work. This collaborative trend is especially strong in moral philosophy, and these three volumes bring together some of the most innovative work by both philosophers and psychologists (...) in this emerging interdisciplinary field. The contributors to volume 2 discuss recent empirical research that uses the diverse methods of cognitive science to investigate moral judgments, emotions, and actions. Each chapter includes an essay, comments on the essay by other scholars, and a reply by the author of the original essay. Topics include moral intuitions as a kind of fast and frugal heuristics, framing effects in moral judgments, an analogy between Chomsky's universal grammar and moral principles, the role of emotions in moral beliefs, moral disagreements, the semantics of moral language, and moral responsibility. Walter Sinnott-Armstrong is Professor of Philosophy and Hardy Professor of Legal Studies at Dartmouth College.

Scholars have a history of crossing intellectual borders (Abbott, 2001). In particular, educators draw from a diversity of intellectuals upon which to base our understanding of, for example, schools and society, curriculum content, teaching, and learning. In addition to icons such as Marx, James, Freud, and Dewey, the works of the Frankfurt School (e.g., Horkheimer, Adorno, Marcuse), Foucault, Gilligan, Derrida, Gramsci, West, Arendt, and Fraser, just to name a few, have been used to guide our scholarship and practice.

Is there a world beyond the senses? Can we perceive future events before they occur? Is it possible to communicate with others without need of our complex sensory-perceptual apparatus that has evolved over hundreds of millions of years? Can our minds/souls/personalities leave our bodies and operate with all the knowledge and information-processing ability that is normally dependent upon the physical brain? Do our personalities survive physical death?

Quantum field theory (QFT) presents a genuine example of the underdetermination of theory by empirical evidence. There are variants of QFT—for example, the standard textbook formulation and the rigorous axiomatic formulation—that are empirically indistinguishable yet support different interpretations. This case is of particular interest to philosophers of physics because, before the philosophical work of interpreting QFT can proceed, the question of which variant should be subject to interpretation must be settled. New arguments are offered for basing the interpretation of QFT (...) on a rigorous axiomatic variant of the theory. The pivotal considerations are the roles that consistency and idealization play in this case. *Received June 2009; revised August 2009. †To contact the author, please write to: Department of Philosophy, University of Waterloo, 200 University Avenue West, Waterloo, ON N2L 3G1, Canada; e‐mail: [email protected].

In the course of the last 30 years, feminist theories of gender have shifted from quasi-Marxist, labor-centered conceptions to putatively ‘post-Marxist’ culture-and identity-based conceptions. Reflecting a broader political move from redistribution to recognition, this shift has been double edged. On the one hand, it has broadened feminist politics to encompass legitimate issues of representation, identity and difference. Yet, in the context of an ascendant neoliberalism, feminist struggles for recognition may be serving less to enrich struggles for redistribution than to displace (...) the latter. Thus, instead of arriving at a broader, richer paradigm that could encompass both redistribution and recognition, feminists appear to have traded one truncated paradigm for another – a truncated economism for a truncated culturalism. This article aims to resist that trend. I propose an anaysis of gender that is broad enough to house the full range of feminist concerns, those central to the old socialist-feminism as well as those rooted in the cultural turn. I also propose a correspondingly broad conception of justice, capable of encompassing both distribution and recognition, and a non-identitarian account of recognition, capable of synergizing with redistribution. I conclude by examining some practical problems that arise when we try to envision institutional reforms that could redress gender maldistribution and gender misrecognition simultaneously. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Kenneth Burke, John Dewey, and the Pursuit of the PublicPaul StobIn Deliberation Day, Bruce Ackerman and James Fishkin argue for the creation of a national holiday, "Deliberation Day," in which citizens come together over a two-day period in their local schools and community centers to deliberate over the merits of presidential candidates and their platforms (Ackerman and Fishkin 2004). While Ackerman and Fishkin propose that the government pay (...) each citizen a $150 stipend for voluntary participation, the purpose is not so much to monetarily to reward citizens for "showing up" as it is to foster an enriched civic culture that would send shockwaves through America's political infrastructure: "If Deliberation Day succeeded, everything else would change: the candidates, the media, the activists, the interest groups, the spin doctors, the advertisers, the pollsters, the fund raisers, the lobbyists, the political parties. All would have no choice but to adapt to a more attentive and informed public" (3). The task of Deliberation Day would be to create a new social context in which citizens could become enlightened through public participation. As the authors conclude the book, "We can, through an act of political imagination, create new institutions for redeeming the ancient promise of democratic citizenship. Ordinary men and women need not be the hapless playthings of the powerful. They can and must find new ways to hold their leaders to account, and redeem their dignity as human beings by responsibly shaping their collective destiny" (219).Ackerman and Fishkin's proposal is indeed filled with political imagination. I bring their proposal to light not to critique the possibilities and limitations of Deliberation Day, but to understand the way in which the authors understand "the public." At the bottom, what the polity needs, Ackerman and Fishkin believe, is a public space dedicated to the reinvigoration [End Page 226] of political culture. It is not that the citizenry is incapable of hammering out intelligent political solutions, but that it needs access to social contexts that facilitate deliberation and the emergence of a common good. To foster a culture of political intelligence, the public needs only the chance to enter the forums that will facilitate thorough, cooperative political decision-making.Ackerman and Fishkin are not alone in calling for access to or creation of these types of forums. Habermas's bourgeois public sphere—a public space in which citizens could come together and rationally debate the activities of the state—essentially represents the evolution of a context, a social space, a public arena (Habermas 1989). The bourgeois public sphere is meant to be egalitarian, providing citizens a forum in which to debate openly and foster a common political consciousness.1 But this sphere has proved problematic for a number of scholars. Oskar Negt and Alexander Kluge (1993), for example, propose a proletarian public sphere to counter capitalism's socioeconomic domination over public resources. Joan Landes (1988) argues that the bourgeois public sphere entails male domination in public life, to the exclusion of women. Nancy Fraser (1992) builds on the feminist critique by adopting the term "counterpublics," collectives of citizens—women, peasants, the working class, and other groups demarcated by issues of race, gender, and ethnicity—that arise in reaction to the dominant public sphere.2In the introduction to Counterpublics and the State (2001), Robert Asen and Daniel Brouwer argue that critiques of the bourgeois public sphere specifically and public sphere theory generally amount to three "reconfigurations" in the way in which scholars think of the public. First, scholars have come to recognize the existence and interaction of multiple public spheres. Second, they have come to acknowledge permeable boundaries of access to the multiple public spheres. Third, scholars have come to recognize the dynamic role of the state in shaping public discourse. One considerable result of these three reconfigurations is an increasing recognition of the political divisions that permeate society (Asen and Brouwer 2001, 17-25).If Asen and Brouwer are right, and I think they are, these three reconfigurations represent the general thrust of contemporary public sphere scholarship, including as it is understood among communication scholars.3 And however diverse such scholarship may be, a few common themes seem to recur across...
