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.

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.

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.

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)

Former Google advertising strategist, now Oxford-trained philosopher James Williams launches a plea to society and to the tech industry to help ensure that the technology we all carry with us every day does not distract us from pursuing our true goals in life. As information becomes ever more plentiful, the resource that is becoming more scarce is our attention. In this 'attention economy', we need to recognise the fundamental impacts of our new information environment on our lives in order (...) to take back control. Drawing on insights ranging from Diogenes to contemporary tech leaders, Williams's thoughtful and impassioned analysis is sure to provoke discussion and debate. Williams is the inaugural winner of the Nine Dots Prize, a new Prize for creative thinking that tackles contemporary social issues. This title is also available as Open Access. (shrink)

"Only a wayfarer born under unruly stars would attempt to put into practice in our epoch of proliferating knowledge the Heraclitean dictum that `men who love wisdom must be inquirers into very many things indeed.'" Thus begins this remarkable interdisciplinary study of time by a master of the subject. And while developing a theory of "time as conflict," J. T. Fraser does offer "many things indeed"--an enormous range of ideas about matter, life, death, evolution, and value.

The Epicurean philosophical system has enjoyed much recent scrutiny, but the question of its philosophical ancestry remains largely neglected. It has often been thought that Epicurus owed only his physical theory of atomism to the fifth-century BC philosopher Democritus, but this study finds that there is much in his ethical thought which can be traced to Democritus. It also finds important influences on Epicurus in Democritus' fourth-century followers such as Anaxarchus and Pyrrho, and in Epicurus' disagreements with his own Democritean (...) teacher Nausiphanes. The result is not only a fascinating reconstruction of a lost tradition, but also an important contribution to the philosophical interpretation of Epicureanism, bearing especially on its ideal of tranquillity and on the relation of ethics to physics.

The infant mortality rate in Liberia is 50 times higher than it is in Sweden, whilst a child born in Japan has a life expectancy at birth of more than double that of one born in Zambia. 1 And within countries, we see differences which are nearly as great. For example, if you were in the USA and travelled the short journey from the poorer parts of Washington to Montgomery County Maryland, you would find that ‘for each mile travelled life (...) expectancy rises about a year and a half. There is a twenty-year gap between poor blacks at one end of the journey and rich whites at the other’. (Marmot, 2004, p.2). There are two types of questions which it is important to ask about inequalities in health such as these. The first are social scientific questions about the extent of inequalities in health and the factors which are causally responsible for these inequalities. Examples of social scientific questions to ask might be: how do infant mortality rates in the UK differ according to social class? What is the difference in life expectancy between Japanese who emigrate to the US and those who remain in Japan? Why do civil servants in higher ranked jobs tend to live longer than civil servants in lower ranked jobs? The second type are normative questions about the reasons we have to care about inequalities in health. Important normative questions to answer are: which inequalities in health should we care about (all inequalities or merely some of them)? When is an inequality in health unjust? How should we weigh our concern for equality in health against other factors such as maximising the.. (shrink)

Linguistic anthropologists have studied emotion in societies around the world for several decades. This article defines the discipline, introduces its general relevance to emotion theory, then presents five of the most important contributions linguistic anthropology has made to the study of emotion.
