Most of us believe that partiality applies in a broad range of relationships. One relationship on which there is much disagreement is co-nationality. Some writers argue that co-national partiality is not justified in certain cases, like killing in war, since killing in defense of co-nationals is intuitively impermissible in other contexts. I argue that this approach overlooks an important structural feature of partiality—namely, that its scope is sometimes restricted. In this essay, I show how some relationships that generate reasons of (...) partiality are restricted in scope—that is, they generate reasons within particular contexts or with respect to particular goods. I then argue that co-national partiality is scope restricted. I then show how this fact helps proponents of co-national partiality overcome the aforementioned objection to its application in cases like war. (shrink)

The COVID-19 global pandemic has shone a light on several important ethical questions, ranging from fairness in resource allocation to the ethical justification of government mandates. In addition to these institutional issues, there are also several ethical questions that arise at the interpersonal level. This essay focuses on several of these issues. In particular, I argue that, despite the insistence in public health messaging that avoiding infecting others constitutes ‘saving lives’, virus transmission that results in death constitutes an act of (...) killing. Whether this killing is wrongful depends on several factors. I consider one intuitively plausible view—namely, that in many cases, killing via unintentional transmission is not wrongful, because the parties in question have implicitly waived their rights against this harm, often via reciprocal risk imposition. I argue that this view is mistaken, but that its central insight can be better captured by identifying the appropriate standards of blame that we ought to apply during a pandemic. I conclude by showing how these conclusions can be fruitfully applied to certain institutional questions, such as helping to justify restricting government mandates. (shrink)

Physicians place significant weight on the distinction between acts and omissions. Most believe that autonomous refusals for procedures, such as blood transfusions and resuscitation, ought to be respected, but they feel no similar obligation to accede to requests for treatment that will, in the physician’s opinion, harm the patient (e.g., assisted death). Thus, there is an asymmetry. In this paper, we challenge the strength of this distinction by arguing that the ordering of values should be the same in both cases. (...) The reason for respecting refusals is that, in such cases, autonomy outweighs well-being. We argue that the same should be true in request cases, which means that requests should not be denied only due to the treatment being too harmful in the physician’s opinion. Our strategy is to consider and reject a number of arguments for the asymmetrical view, including an appeal to the doing–allowing distinction and positive and negative rights. The duty to respect refusals is still greater than the duty to grant requests on our view, but, by arguing that the ordering of values is the same in both cases, we show that there is less of a distinction in healthcare between requests and refusals than many currently believe.

Most people who defend physician-assisted death (PAD) endorse the Joint View, which holds that two conditions—autonomy and welfare—must be satisfied for PAD to be justified. In this paper, we defend an Autonomy Only view. We argue that the welfare condition is either otiose on the most plausible account of the autonomy condition, or else is implausibly restrictive, particularly once we account for the broad range of reasons patients cite for desiring PAD, such as “tired of life” cases. Moreover, many of (...) the common objections to an Autonomy Only view fail once we understand the extent of the autonomy condition’s requirements—in particular, the importance of one’s values for autonomous choices. If our view is correct, then the scope of permissible PAD is broader than is currently accepted in both the philosophical literature and the law, and therefore poses an important challenge to this widely accepted view on justified PAD.

At some point in the future – perhaps within the next few decades – it will be possible for foetuses to develop completely outside the womb. Ectogenesis, as this technology is called, raises substantial issues for the abortion debate. One such issue is that it will become possible for a woman to have an abortion, in the sense of having the foetus removed from her body, but for the foetus to be kept alive. We argue that while there is a (...) right to an abortion, there are reasons to doubt that there is a right to the death of the foetus. Our strategy in this essay is to consider and reject three arguments in favour of this latter right. The first claims that women have a right not to be biological mothers, the second that women have a right to genetic privacy, and the third that a foetus is one's property. Furthermore, we argue that it follows from rejecting the third claim that genetic parents also lack a right to the destruction of cryopreserved embryos used for in vitro fertilization. The conclusion that a woman possesses no right to the death of the foetus builds upon the claims that other pro-choice advocates, such as Judith Jarvis Thomson, have made. (shrink)

Recent studies have shown that recidivism scoring algorithms like COMPAS have significant racial bias: Black defendants are roughly twice as likely as white defendants to be mistakenly classified as medium- or high-risk. This has led some to call for abolishing COMPAS. But many others have argued that algorithms should instead be given access to a defendant's race, which, perhaps counterintuitively, is likely to improve outcomes. This approach can involve either establishing race-sensitive risk thresholds, or distinct racial ‘tracks’. Is there a (...) moral difference between these two approaches? We first consider Deborah Hellman's view that the use of distinct racial tracks (but not distinct thresholds) does not constitute disparate treatment since the effects on individuals are indirect and does not rely on a racial generalization. We argue that this is mistaken: the use of different racial tracks seems both to have direct effects on and to rely on a racial generalization. We then offer an alternative understanding of the distinction between these two approaches—namely, that the use of different cut points is to the counterfactual comparative disadvantage, ex ante, of all white defendants, while the use of different racial tracks can in principle be to the advantage of all groups, though some defendants in both groups will fare worse. Does this mean that the use of cut points is impermissible? Ultimately, we argue, while there are reasons to be skeptical of the use of distinct cut points, it is an open question whether these reasons suffice to make a difference to their moral permissibility.

This paper synthesizes scholarship from several academic disciplines to identify and analyze five major ethical challenges facing data-driven policing. Because the term “data-driven policing” emcompasses a broad swath of technologies, we first outline several data-driven policing initiatives currently in use in the United States. We then lay out the five ethical challenges. Certain of these challenges have received considerable attention already, while others have been largely overlooked. In many cases, the challenges have been articulated in the context of related discussions, (...) but their distinctively ethical dimensions have not been explored in much detail. Our goal here is to articulate and clarify these ethical challenges, while also highlighting areas where these issues intersect and overlap. Ultimately, responsible data-driven policing requires collaboration between communities, academics, technology developers, police departments, and policy-makers to confront and address these challenges. And as we will see, it may also require critically reexamining the role and value of police in society. (shrink)

In this paper, we argue that promoting patient values is a legitimate goal of medicine. Our view offers a justification for certain current practices, including birth control and living organ donation, that are widely accepted but do not fit neatly within the most common extant accounts of the goals of medicine. Moreover, we argue that recognising value promotion as a goal of medicine will expand the scope of medical practice by including some procedures that are sometimes rejected as being outside (...) the scope of acceptable medical practice, such as certain forms of physician-assisted death. We then rebut some common and possible objections to this view. Our aim is not to argue that other accounts are mistaken—except when they argue for a single goal that does not include patient values—but rather to show that value promotion should play a more central role in discussions about the goals of medicine.

Alienation and Connection addresses social constructs that perpetuate alienation through suffering. The contributors discuss how alienation through suffering in a variety of contexts can be transformed into connection and reconnection: human relationship with the environment, economic and social systems that disconnect and reconnect, cultural constructs that divide or can heal, encountered difference that brings opportunity, and various manifestations of personal pain that can be survived and even overcome.

Most philosophers writing on the ethics of war endorse “reductivist individualism,” a view that holds both that killing in war is subject to the very same principles of ordinary morality ; and that morality concerns individuals and their rights, and does not treat collectives as having any special status. I argue that this commitment to individualism poses problems for this view in the case of national defense. More specifically, I argue that the main strategies for defending individualist approaches to national (...) defense either fail by their own lights or yield deeply counterintuitive implications. I then offer the foundations for a collectivist approach. I argue that such an approach must do justice to the collective goods that properly constituted states make possible and protect through certain acts of defensive war; and that any such picture of national defense must make room for some form of national partiality.

Alan Tomhave and Mark Vopat have argued that organized boycotts against the expressive acts of companies and their leaders are pro tanto morally wrong because they constitute an attempt to silence voices in the marketplace of ideas. I argue that such boycotts are not best viewed as attempts to silence, but rather as a morally permissible form of withdrawal of support of certain expressive acts.

A common criticism of the use of algorithms in criminal justice is that algorithms and their determinations are in some sense ‘opaque’—that is, difficult or impossible to understand, whether because of their complexity or because of intellectual property protections. Scholars have noted some key problems with opacity, including that opacity can mask unfair treatment and threaten public accountability. In this paper, we explore a different but related concern with algorithmic opacity, which centers on the role of public trust in grounding (...) the legitimacy of criminal justice institutions. We argue that algorithmic opacity threatens the trustworthiness of criminal justice institutions, which in turn threatens their legitimacy. We first offer an account of institutional trustworthiness before showing how opacity threatens to undermine an institution’s trustworthiness. We then explore how threats to trustworthiness affect institutional legitimacy. Finally, we offer some policy recommendations to mitigate the threat to trustworthiness posed by the opacity problem.

Bilingualism has been identified as a potential cognitive factor linked to delayed onset of dementia as well as boosting executive functions in healthy individuals. However, more recently, this claim has been called into question following several failed replications. It remains unclear whether these contradictory findings reflect how bilingualism is defined between studies, or methodological limitations when measuring the bilingual effect. One key issue is that despite the claims that bilingualism yields general protection to cognitive processes, studies reporting putative bilingual differences (...) are often focused on domain specific experimental paradigms. This study chose a broader approach, by considering the consequences of bilingualism on a wide range of cognitive functions within individuals. We utilised 19 measures of different cognitive functions commonly associated with bilingual effects, to form a “cognitive profile” for 215 non-clinical participants. We recruited Welsh speakers, who as a group of bilinguals were highly homogeneous, as means of isolating the bilingualism criterion. We sought to determine if such analyses would independently classify bilingual/monolingual participant groups based on emergent patterns driven by collected cognitive profiles, such that population differences would emerge. Multiple predictive models were trained to independently recognise the cognitive profiles of bilinguals, older adults and higher education attainment. Despite managing to successfully classify cognitive profiles based on age and education, the model failed to differentiate between bilingual and monolingual cognitive ability at a rate greater than that of chance. Repeated modelling using alternative definitions of bilingualism, and just the older adults, yielded similar results. In all cases then, using our “bottom–up” analytical approach, there was no evidence that bilingualism as a variable indicated differential cognitive performance – as a consequence, we conclude that bilinguals are not cognitively different from their monolingual counterparts, even in older demographics. We suggest that studies that have reported a bilingual advantage could well have confounded other key variables that may be driving reported advantages. We recommend that future research refine the machine learning methods used in this study to further investigate the complex relationship between bilingualism and cognition. (shrink)

Violent extremism is often explicitly motivated by commitment to abstract ideals such as the nation or divine law – so-called “sacred” values that are relatively insensitive to material incentives and define our primary reference groups. Moreover, extreme pro-group behavior seems to intensify after social exclusion. This fMRI study explores underlying neural and behavioral relationships between sacred values, violent extremism, and social exclusion. Ethnographic fieldwork and psychological surveys were carried out among young men from a European Muslim community in neighborhoods in (...) and around Barcelona, Spain. Candidates for an fMRI experiment were selected from those who expressed willingness to engage in or facilitate, violence associated with jihadist causes. In the scanner, participants were assessed for their willingness to fight and die for in-group sacred values before and after an experimental manipulation using Cyberball, a toss ball game known to yield strong feelings of social exclusion. Results indicate that neural activity associated with sacred value processing in a sample vulnerable to recruitment into violent extremism shows marked activity in the left inferior frontal gyrus, a region previously associated with sacred values and rule retrieval. Participants also behaviorally expressed greater willingness to fight and die for sacred versus non-sacred values, consistent with previous studies of combatants and noncombatants. The social exclusion manipulation specifically affected non-sacred values, increasing their similarities with sacred values in terms of heightened left inferior frontal activity and greater expressed willingness to fight and die. These findings suggest that sacralization of values interacts with willingness to engage in extreme behavior in populations vulnerable to radicalization. In addition, social exclusion may be a relevant factor motivating violent extremism and consolidation of sacred values. If so, counteracting social exclusion and sacralization of values should figure into policies to prevent radicalization. (shrink)

In this brief reply to Stephen Davis, I argue that Davis’s separationist position, wherein those who remain eternally apart from God do so by choice, is internally contradictory in that it leads to universalism.

In this book Jeremy Dunning-Davies deals with the influence that "conventional wisdom" has on science, scientific research and development. He sets out to explode' the mythical conception that all scientific topics are open for free discussion and argues that no-one can openly raise questions about relativity, dispute the 'Big Bang' theory, or the existence of black holes, which all seem to be accepted facts of science rather than science fiction. In today's modern climate with "Britain's radioactive refuse heap already (...) big enough to fill the Royal Albert Hall" (Edmund Conway, Economics Editor The Daily Telegraph 28.11.06), it is alarming that there are potential advances in hadronic mechanics which could conceivably pave the way for new clean energies and even a safe in-house method for the disposal of nuclear waste, that have not even been considered by the present establishment. These examples are from the field of physics but there can be little doubt that outside factors have affected the progress of most, if not all, branches of science for many years. Factors other than purely scientific ones still appear to be exerting tremendous influences on progress in a wide variety of fields. Is it too idealistic or nai;ve, to expect that science should remain pure and stay unaffected by such factors? Dr Dunning-Davies presents a beautifully written argument that if science is to progress, and be of any real use, these external factors must be held at bay. (shrink)

[Given, If, Then] attempts to conceive a possibility of reading, through a set of readings: reading being understood as the relation to an Other that occurs prior to any semantic or formal identification, and, therefore, prior to any attempt at assimilating, or appropriating, what is being read to the one who reads. As such, it is an encounter with an indeterminable Other, an Other who is other than other -- an unconditional relation, and thus a relation to no fixed object (...) of relation. The first reading by Jeremy Fernando, "Blind Reading," unfolds through an attempt to speak of reading as an event. Untheorisable in itself, it is a positing of reading as reading, through reading, where texts are read as a test site for reading itself. As such, it is a meditation on the finitude and exteriority in literature, philosophy, and knowledge; where blindness is both the condition and limit of reading itself. Folded into, or in between, this (re)reading are a selection of photographs from Jennifer Hope Davy's image archive. They are on the one hand simply a selection of 'impartial pictures' taken, and on the other hand that which allow for something singular and, therefore, always other to dis/appear -- crossing that borderless realm between 'some' and 'some-thing.' Eventually, there is a writing on images on writings by Julia Hölzl. A responding to the impossible response, a re-iteration, a re-reading of what could not have been written, a re-writing of what could not have been read; these poems, if one were to name them such, name them as such, answer (to) the impossibility of answering: answer to no call.

Incredible discoveries from the fringes of the universe to the inner workings of our mindsÑall from nothing! It turns out that almost nothing is as curiousÑor as enlighteningÑas, well, nothing. What is nothingness? Where can it be found?

How might cooling matter down almost to absolute zero help solve our energy crisis? How can someone suffer from a false diagnosis as though it were true? Does nothingness even exist? Recent experiments suggest that squeezing a perfect vacuum somehow creates light. Why is it unfair to accuse slothsÑanimals who do nothingÑof being lazy? And more! Contributors Paul Davies, Jo Marchant, and Ian Stewart, along with two former editors of Nature and 16 other leading writers and scientists, marshal up-to-the-minute research to make one of the most perplexing realms in science dazzlingly clear. Prepare to be amazed at how much more there is to nothing than you ever realized. (shrink)

The current status of localization and related concepts, especially localized statevectors and position operators, within Lorentz-invariant Quantum Theory (LIQT) is ambiguous and controversial.1 Ever since the early work of Newton & Wigner (1949), and the subsequent extensions of their work, particularly by Hegerfeldt (1974, 1985), it has seemed impossible to identify localized statevectors or position operators in LIQT that were not counterintuitive—strange—in one way or another; the most striking strange property being the superluminal propagation of the localized states. The ambiguous (...) and controversial status of these concepts arises from the varied reactions that workers have to the strange properties. Some regard them, particularly the superluminal propagation, as utterly unacceptable, and conclude that no precise concepts of localized statevectors and position operators exist in LIQT (Wigner 1973, p. 325-327; 1983, pp. 310-313; Malament 1996). Others downplay the whole issue, on the grounds that current theoretical and experimental practice has no need of sharply formulated concepts of localization, localized states etc. (Birrell & Davies 1984, pp. 48-59; Haag 1992, p. 34). Still others, including ourselves, believe that the superluminal propagation does not lead to causal contradictions, and is not in conflict with available empirical data: so that it should not be ruled out. We also believe that the other strange properties are merely unfamiliar novelties of LIQT which we must simply learn to accept. (Like the superluminal propagation, they do not lead to causal contradictions, nor conflict with available data.) So in this paper, we aim to help remove the ambiguous and controversial status of localization concepts in LIQT. Overall, our strategy will be to assess a number of localization concepts, and thereby clarify the often complex relationships among them. (shrink)

Waged in 2016, Philippine President Rodrigo Duterte’s war on drugs has claimed over 20,000 lives according to human rights groups. The Duterte administration’s own count is significantly lower: around 6,000. The huge discrepancy between the government’s official count and that of arguably more impartial organizations about something as concretely material as body count is symptomatic of how disinformation is central to the Duterte administration and how it can sustain the approval of the majority of the Philippine electorate. We suggest that (...) Duterte’s populist politics generates what Boler and Davis call “affective feedback loops,” which create emotional and informational ecosystems that facilitate smooth algorithmic governance. We turn to Patron Saints of Nothing, a recently published novel by Randy Ribay about a Filipino-American who goes back to the Philippines to uncover the truth behind the death of his cousin. Jay’s journey into the “heart of darkness” as a “hyphenated” individual allows him access to locally networked subjectivities but not its affective entanglements. Throughout the novel, he encounters numerous versions of the circumstances of Jun’s demise and the truth remains elusive at the end of the novel. We argue that despite the constant distortion of fact and fiction in the novel, what remains relatively stable or “sticky” throughout the novel are the letters from Jun Reguero that Jay carries with him back to the Philippines. We suggest that these letters can potentially serve as a form of “dissensus” that challenges the constant redistribution of the sensible in the novel. (shrink)

The French philosopher Jacques Rancière is well known across the world for his groundbreaking contributions to aesthetic and political theory and for his radical rethinking of the question of equality. This much-needed new collection situates Rancière's thought in a range of practical and theoretical contexts. These specially commissioned essays cover the complete history of Rancière's work and reflect its interdisciplinary reach. They span his early historical research of the 1960s and '70s, his celebrated critique of pedagogy and his later political (...) theory of dissensus and disagreement, as well as his ongoing analysis of literature and 'the aesthetic regime of art'. Rancière's resistance to psychoanalytic thinking is also explored, as are his most recent publications on film and film theory. Contributors include Tom Conley, Carolyn Steedman, Geneviève Fraisse, Jean-Luc Nancy, Jeremy Lane, and many more. The book also includes a brand new interview with Rancière, reflecting on his intellectual project and developing new lines of thought from his latest major work, _Aisthesis_. _Rancière Now_ will be essential reading for students and scholars across the humanities and social sciences; it will stimulate and inspire discussion of Rancière’s work for years to come.

We then discuss the emergence of time in simple quantum geometrodynamics, and in the Euclidean approach. Section 6 (...) concludes. (shrink)

La menzogna è irrinunciabile per vincere in politica? Davi ci spiega quali sono i meccanismi di persuasione a cui ricorrono taluni politici per farsi eleggere e quali le responsabilità di quegli elettori che scelgono comunque di votare chi sostiene anche ciò che non può essere vero. È indubbio che la comunicazione politica si rifaccia al simbolismo e al linguaggio delle favole; non necessariamente per occultare la realtà, ma più direttamente per esprimere con maggiore efficacia il suo messaggio. Alle celebri favole (...) di 'Biancaneve', 'Cenerentola', 'Il brutto anatroccolo' sono ricorsi infatti uomini politici del calibro di Berlusconi, Prodi, Nixon, Carter, Mitterrand e partiti quali la Democrazia Cristiana; l'hanno fatto per conquistare voti ma anche per attivare ampi meccanismi di consenso che attingessero direttamente dall'inconscio collettivo.

Bush. (shrink)

Author Jeremy Waldron has thoroughly revised thirteen of his most recent essays in order to offer a comprehensive critique of the idea of the judicial review of legislation. He argues that a belief in rights is not the same as a commitment to a Bill of Rights. This book presents legislation by a representative assembly as a form of law making which is especially apt for a society whose members disagree with one another about fundamental issues of principle.

This philosophical treatise on the foundations of semantics is a systematic effort to clarify, deepen, and defend the classical doctrine that words are conventional signs of mental states, principally thoughts and ideas, and that meaning consists in their expression. This expression theory of meaning is developed by carrying out the Gricean program, explaining what it is for words to have meaning in terms of speaker meaning, and what it is for a speaker to mean something in terms of intention. But (...) Grice's own formulations are rejected and alternatives developed. The foundations of the expression theory are explored at length, and the author develops the theory of thought as a fundamental cognitive phenomenon distinct from belief and desire, argues for the thesis that thoughts have parts, and identifies ideas or concepts with parts of thoughts. This book will appeal to students and professionals interested in the philosophy of language. (shrink)

Since its founding in the nineteenth century, social anthropology has been seen as the study of exotic peoples in faraway places. But today more and more anthropologists are dedicating themselves not just to observing but to understanding and helping solve social problems wherever they occur--in international aid organizations, British TV studios, American hospitals, or racist enclaves in Eastern Europe, for example. In Exotic No More , an initiative of the Royal Anthropological Institute, some of today's most respected anthropologists demonstrate, in (...) clear, unpretentious prose, the tremendous contributions that anthropology can make to contemporary society. They cover issues ranging from fundamentalism to forced migration, child labor to crack dealing, human rights to hunger, ethnicity to environmentalism, intellectual property rights to international capitalisms. But Exotic No More is more than a litany of gloom and doom the essays also explore topics usually associated with leisure or "high" culture, including the media, visual arts, tourism, and music. Each author uses specific examples from their fieldwork to illustrate their discussions, and 62 photographs enliven the text. Throughout the book, the contributors highlight anthropology's commitment to taking people seriously on their own terms, paying close attention to what they are saying and doing, and trying to understand how they see the world and why. Sometimes this bottom-up perspective makes the strange familiar, but it can also make the familiar strange, exposing the cultural basis of seemingly "natural" behaviors and challenging us to rethink some of our most cherished ideas--about gender, "free" markets, "race," and "refugees," among many others.

Negative Ecstasies discusses the contribution and significance of the work of Georges Bataille to the contemporary study of religion and theology, collecting essays that examine specific case studies and make connections to other significant scholars in the field.

Western philosophers have traditionally concentrated on theory as the means for expressing knowledge about a variety of phenomena. This absorbing book challenges this fundamental notion by showing how objects themselves, specifically scientific instruments, can express knowledge. As he considers numerous intriguing examples, Davis Baird gives us the tools to "read" the material products of science and technology and to understand their place in culture. Making a provocative and original challenge to our conception of knowledge itself, _Thing Knowledge _demands that (...) we take a new look at theories of science and technology, knowledge, progress, and change.

The contractarian theory elaborated by John Rawls in A Theory of Justice exploits the difference principle in a great many ways. Rawls argues that, when used as part of a set of guiding principles for structuring the basic institutions of society, it simplifies the problem of interpersonal comparisons (91-4)1, helps compensate for the arbitrariness of natural endowments (101-3), promotes a harmony of interests between citizens (104-5), reintroduces the principle of fraternity to democratic society (105-6), and, what is critical to his (...) contractarian theory, it is an essential part of the principles of justice which would be chosen by free, equal, and rational persons in the original position.

As idealized descriptions of mathematical language, there is a sense in which formal systems specify too little, and there is a sense in which they specify too much. On the one hand, formal languages fail to account for a number of features of informal mathematical language that are essential to the communicative and inferential goals of the subject. On the other hand, many of these features are independent of the choice of a formal foundation, so grounding their analysis on a (...) particular choice of a formal system introduces unnecessary specificity. This chapter begins to map out the design features of mathematical language without descending to the level of formal implementation, drawing on examples from the mathematical literature and insights from the design of computational proof assistants and their libraries.

We have two aims. The main one is to expound the idea of renormalization in quantum field theory, with no technical prerequisites. Our motivation is that renormalization is undoubtedly one of the great ideas—and great successes--of twentieth-century physics. Also it has strongly influenced in diverse ways, how physicists conceive of physical theories. So it is of considerable philosophical interest. Second, we will briefly relate renormalization to Ernest Nagel's account of inter-theoretic relations, especially reduction. One theme will be a contrast between (...) two approaches to renormalization. The old approach, which prevailed from ca. 1945 to 1970, treated renormalizability as a necessary condition for being an acceptable quantum field theory. On this approach, it is a piece of great good fortune that high energy physicists can formulate renormalizable quantum field theories that are so empirically successful. But the new approach to renormalization explains why the phenomena we see, at the energies we can access in our particle accelerators, are described by a renormalizable quantum field theory. For whatever non-renormalizable interactions may occur at yet higher energies, they are insignificant at accessible energies. Thus the new approach explains why our best fundamental theories have a feature, viz. renormalizability, which the old approach treated as a selection principle for theories. That is worth saying since philosophers tend to think of scientific explanation as only explaining an individual event, or perhaps a single law, or at most deducing one theory as a special case of another. Here we see a framework in which there is a space of theories. And this framework is powerful enough to deduce that what seemed “manna from heaven” is to be expected: the good fortune is generic. We also maintain that universality, a concept stressed in renormalization theory, is essentially the familiar philosophical idea of multiple realizability; and that it causes no problems for reductions of a Nagelian kind.

Plato is often acknowledged as the first philosophical critic of democracy and his Republic is regularly taken as a paradigm of an anti-democratic work. While it is true that Plato objected to much about the democracy of his own time, Plato’s political theorizing also reveals an interest in improving democratic institutions. This chapter explores three themes in Plato’s thinking about democracy: firstly, Plato's insistence that rulers should be knowledgeable and his claim that most people are politically incompetent (§1); secondly, Plato's (...) criticisms of oratory and the corrupting effects of public rhetoric (§2); thirdly, Plato's use of democratic institutions in the Laws (§3). Once we appreciate these different evaluations of democratic practices, we can see that Plato was not simply ‘anti-democratic’ or ‘pro-democratic’ but thought some democratic practices should be abandoned, some reformed, and some adopted.
