Tobacco mosaic virus has served as a model organism for pathbreaking work in plant pathology, virology, biochemistry and applied genetics for more than a century. We were intrigued by a photograph published in Phytopathology in 1934 showing that Tabasco pepper plants responded to TMV infection with localized necrotic lesions, followed by abscission of the inoculated leaves. This dramatic outcome of a biological response to infection observed by Francis O. Holmes, a virologist at the Rockefeller Institute for Medical Research, was used (...) to score plants for resistance to TMV infection. Our objective was to gain a better understanding of early to mid-twentieth century ideas of genetic resistance to viruses in crop plants. We investigated Holmes’ observation as a practical exercise in reworking an experiment, having been inspired by Pamela Smith’s innovative Making and Knowing Project. We had a great deal of difficulty replicating Holmes’ experiment, finding that biological materials and experimental customs change over time, in ways that ideas do not. Using complementary tools plus careful study and interpretation of the original text and figures, we were able to rework, yet only partially replicate, this experiment. Reading peer-reviewed manuscripts that cited Holmes’ 1934 report provided an additional level of insight into the interpretation and replication of this work in the decades that followed. From this, we touch on how experimental reworking can inform our strategies to address the reproducibility “crisis” in twenty-first century science. (shrink)

I. INTRODUCTIONThe Parshall Flume, which was invented in 1920 by R. Parshall, is mostly used in wastewater and crop supply. Utilizing equations, Parshall established dimensions that fit the design, one of the advantages is the conversion of position energy to velocity energy since in other measurement structures there are minimum energy losses in this one it does not allow sedimentation. The structuring of the project is adhered to by different models that define its behavior and limit its use. This is (...) the case of an approach length of the channel entrance, which is nothing more than a primary distance for the action of the flow within the channel. Throughout history, some studies were conducted in an attempt to establish an approximate and realistic value of the length at the time of measurements, but the theories put forward were lost. Some people link this length with the narrowing of the gorge, and others suggest flow conditions before entering the flume. For the development of the project established with its respective objectives, the respective structuring was carried out: For the measurement, the points already established in the field will be taken with the help of a total station, GPS, to verify the respective measurements of the Parshall flume. For the calculations and the design, the points will be introduced in the civil 3D to be able to verify if the points taken are the correct ones and what distances they have between them, through this, we can apply different methods to be able to verify the design that has this Parshall flume. For the evaluation and layout of the gutter, if it is the case, we will carry out a layout in plan with the data already calculated in the office and we will evaluate the situation in which it is so that we can apply a possible solution so that a defect does not occur. In this report, we focus on the design and redesign of a hydraulic irrigation channel where we find a Parshall section, which has the function of measuring the flow found in that section. The measurements found in the field can be verified in the office using formulas and software to verify if the data are correct, if so we can say that it is well designed, otherwise we will look for a possible solution by doing a field study.

It is an honor and also a pleasure to respond to the three philosophers who have devoted so much time and careful attention to reading and critiquing my paper "Nations of Immigrants: Do Words Matter?" As an interdisciplinary scholar who interacts more often with specialists in the social sciences, history, and Italian studies than with philosophers, I was unsure what to expect from the Coss Dialogue. Would it be possible to find words common enough to all that we could begin (...) to address the complex issues raised by national mythology about the United States as a nation of immigrants? I believe that our panel discussions revealed the common ground we rather quickly found. But they also uncovered a few gaping chasms. (shrink)

Racism as an independent topic of investigation in philosophy has considerably developed since the 1990s, when it appeared as part of growing debates that, on the one hand, investigated the political meaning of race and, on the other, its ontology and whether it existed at all. Likewise, with the idea of racism, its broadly normative meaning is critiqued by some philosophers, while others ask how best to conceive of it and identify its immorality. There were a few early and significant (...) forays in philosophy about the nature of racism, of which three works stand out because of the way they set the terms of the debate: David Theo Goldberg's Racist Culture, Charles W. Mills’ The Racial Contract, and Jorge L.A. Garcia's “The Heart of Racism.”1 This collection reacts to the latter fork in the discussion but does so in ways that significantly touch on the former.The collection begins with Jorge L. Garcia's “Virtue Ethics in Social Theory: Defending a Volitional Analysis of Racism from Tommie Shelby's Challenges.” It is a clarification and defense of his influential volitional analysis of racism (VAR) from three prominent objections: that VAR inadequately accounts for the immorality of racism because it relies on the assumed wrongness of racism built into ordinary usage of the term ‘racist;’ that it mistakenly separates intention from belief; and that it does not fully account for the racism of some troubling mental states that cannot be traced back to a racist ill-will. Garcia's account of racism as fundamentally rooted in racist ill-will, along with Lawrence Blum's, is representative of agent-centered theories of racism. Not only do they attempt to explain individual or personal racism, but they also hold that racism in institutions, structures, or systems traces back to the racism of persons.Current accounts of structural racism, however, claim that it exists and operates independently of infection from intentionally racist persons, that the focus on racist persons cannot adequately account for how racism works in society, and that, instead, we should concentrate on structures and ideologies. Amelia Wirts sharply defends this view in her, “What does it mean to say ‘The Criminal Justice System is Racist’?” She explains how structural racism applies to America's criminal justice system and other “intermediate” (between individual and societal level) structures. Wirts argues that personal accounts of racism, and in particular Garcia's VAR, do not adequately account for the patterns of racial disparity in the criminal justice system or its disproportionate harm to black people. She advocates, instead, for a patterned view of structural racism, the patterns of which operate “as if it were designed to disproportionately harm” some racialized group. Additionally, Wirts adds that such patterns are particularly racist when they fuel racist ideological symbols, as the criminal justice system does in relation to the idea of the black criminal.Structural analyses of racism are powerfully instructive, and Alisa Bierria, in “Structural Racism Within Reason,” offers an account that takes an epistemic turn that advances our understanding of their meaning. More than the idea that personal and structural racism beget each other in continuous looping effects, and more than the view that racism is best understood as an ideology that provides the content to racist attitudes or policy proscriptions, she argues that structural racism structures reason. Drawing on the 2012 case of Marissa Alexander, who unsuccessfully tried to use Florida's Stand Your Ground Law to justify her firing a warning shot at her estranged, abusive husband to protect herself from his murderous threat, Bierra argues that structural racism extends constructed and controlling intentions onto its targets, and, as in the case she discusses, it uses those constructed and fictional intentions to justify their punishment and depriving them of equal justice.Structural analyses of racism are essential additions to the philosophical understanding of racism that have appropriately challenged the centrality of agent-centered accounts. The increasing academic focus on structural explanations, however, along with the current overuse of “systemic racism” in popular discourse, threatens to eclipse the value of accounts of agent-centered accounts. In “Is Racism Essentially Systemic?” Michael Hardimon counsels against this trend. He reminds us that racism is not essentially systemic, and that the dominance of structural explanations could obscure its other forms and even the proper understanding of structural racism. Indeed, structures once constructed might operate independently of human intention, but they are designed, initiated, and often operated by persons.After considering the direction of the current philosophical discussion about the meaning of racism and its immorality, the next set of articles expands the discussion into matters of class, xenophobia, and white nationalism. Lawrence Blum's “Race and Class Together” starts it off. Blum builds class into his analysis of racism and critiques its absence in anti-racist theory. He argues that paying attention to class is required to secure justice for the victims of racism because pursuing justice is often a matter of both. Blum contends that race and class are “normatively distinct axes of injustice” and that, depending on the question, racial injustice needs to be addressed separately. However, there are aspects of racial injustice that can only be dealt with through a class analysis and require class or combined class–race focused policies. Pointing to the fact that many of the members of groups targeted by racism (he considers blacks, Indigenous peoples, and Latinxs) share cross-class interests, which includes shared interests with some whites, which they do not share with more economically privileged members of their own groups, Blum argues that these interests should be addressed through “class-focused policies,” in a manner that will secure justice for disadvantaged racial groups.Shifting from the class-race analysis, José Jorge Mendoza, in “‘Go Back to Where You Came From!’ Racism, Xenophobia, and White Nationalism,” turns our attention toward white nationalism to examine whether it is best understood as an expression of racism or xenophobia. Although he recognizes the importance of xenophobia in white nationalism, Mendoza does not neglect its connections with racist ideas. However, he acknowledges that emphasizing the role of race in condemnations of white nationalism risks overextending the concept of race, i.e., in regards to pan-racial groups, because some members of those groups are racially identified as white. Thus, the charge of racism against white nationalism in such cases may not clearly apply. To deal with those cases, Mendoza cleverly decouples the ideas of “radicalization” and “racial formation,” and he puts forward a new concept, “racial disintegration,” to account for the operation and shifting targets of white nationalism.In the final piece, David H. Kim and I discuss xenophobia and racism in the case of “Anti-Asian Racism.” We move from general theories of racism to inquire about what is at the base of anti-Asian racism. Little is said in contemporary accounts of racism about anti-Asian racism. This is due, in part, to the high level of abstraction in those discussions but also because much of the literature takes anti-blackness as the model of racism. Our piece addresses this lacuna in a manner not beholden to the black-white binary. We discuss how the idea of anti-Asian racism is a conceptual problem in the American context dominated by that binary. We then argue that xenophobia as a form of civic ostracism, and to some extent xenophilia, play a particular role in how anti-Asian racism functions and its immorality.The pieces in this collection resonate with current events and controversies involving racism and illustrate the potential of the debate to relate to and speak those events, not just to the specialized interests of a cloistered academic conversation. Each piece demonstrates the potential for extending vital lines of debate and discussion that touches the raw nerve of the public discussion of racism. (shrink)

El presente trabajo aborda de forma introductoria la exploración y explotación minera en la región de Cuyo y el norte neuquino durante las primeras décadas del siglo XIX. Para esto se analizarán las campañas militares de José Félix Aldao y Pedro Pascual Segura hacia “tierra adentro” y sus vínculos tanto con el contexto político y económico de Mendoza como con la situación de las relaciones interétnicas en la frontera sur de dicha provincia. La hipótesis de la que parte el (...) trabajo es que la crisis económica vivida en Mendoza —la cual estuvo acrecentada por los conflictos político y el deterioro de las relaciones diplomáticas con los principales líderes indígenas— llevó a que se impulsen ambas campañas militares con el fin tanto de eliminar a las parcialidades que no eran aliadas como de explorar y adquirir nuevos recursos económicos, entre ellos nuevos yacimientos mineros situados en territorios indígenas. Metodológicamente, se parte principalmente del análisis de fuentes documentales éditas, de las cuales se obtuvieron los datos con los cuales se llevó adelante el presente estudio. (shrink)

Women are twice as likely to be diagnosed with a depressive disorder as men. Before trying to explain this difference, we must first understand how women experience depression. We explore the phenomenon of depression through women’s experiences, using Giorgi’s descriptive phenomenological method. An essential meaning structure describes the development of depression: The women find themselves entrapped in a personal mission which had backfired. Motivated by shame and guilt from the past, they overinvest in work or others’ emotions to relieve internal (...) pain. They feel deeply sensitive to, and responsible for, other persons’ distress while ignoring their own feelings and needs. Gradually their emotional body grows awry and acts in increasingly alienating and threatening ways. Ultimately they feel forced to submerge in their emotional body; they succumb to depression. We reflect on this structure on the basis of Minkowski, Scheler, Sartre and Merleau-Ponty, and in relation to contemporary research on depression. (shrink)

The concepts of judicial independence and the separation of powers are used more as terms of political rhetoric than legal concepts in the British constitution. Responsible government significantly merges the executive and the legislative while parliamentary sovereignty has meant that judicial independence has had a peculiar British meaning, rarely unpacked. In practice, in England, (and presumably in the other UK jurisdictions), individual judges are accorded a high degree of independence, while there is no effective independence of the judiciary collectively as (...) a branch of government. This article then asks what impact current constitutional changes will have on this state of affairs. Adherence to the EU, the growth of judicial review and other factors have already had an important impact; devolution, the Human Rights Act and the reform of the House of Lords may have impacts that will be different in both quality and degree. Coupled with other political changes the end result may well be a more effective separation of powers and more real independence for the judges as a branch of government; but that in turn may call for more open and meaningful democratic control over the appointment of judges.

This book is divided into three parts: in Part I, R. M. Hare offers a justification for the use of philosophy of language in the treatment of moral questions, together with an overview of his moral philosophy of ‘universal prescriptivism’. The second part, and the core of the book, consists of five chapters originally presented as a lecture series under the title ‘A Taxonomy of Ethical Theories’. Hare identifies descriptivism and non‐descriptivism as the two main positions in modern moral philosophy. (...) The former he divides into Naturalism and Intuitionism, and the latter into Emotivism and Rationalism. Hare argues that all forms of descriptivism tend to lead to Relativism because the truth conditions of moral statements are culturally variant. Of the positions discussed, only Hare's own position, a form of Rationalism, which he calls Universal Prescriptivism, meets all of the requirements that an adequate ethical theory should meet. Part III consists of Hare's previously published essay ‘Could Kant have been a Utilitarian?’ (Utilitas 5, 1993). Here, Hare puts forward the controversial thesis that Kant's moral philosophy is, in its basic principles, compatible with utilitarianism. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:preface This special issue provokes a conversation between decolonial and postcolonial feminisms by asking what they are, how they speak about each other, and how they can speak to each other. Read together, the articles engage and sometimes trouble the temporal and spatial distinctions drawn between decolonial and postcolonial approaches. Kiran Asher explores overlaps between decolonial and postcolonial thought by comparing the ideas of Gayatri Chakravorty Spivak and Silvia (...) Rivera Cusicanqui on representation. Aimee Carrillo Rowe also stages a dialogue between these approaches when interrogating her family ’s Chican@ settler history. Tiara R. Na’puti and Judy Rohrer offer an account of how recent scholarship from Hawai‘i and Guåhan (Guam) has elaborated Indigenous epistemologies in settler contexts. Two articles excavate colonialism’s relationship to science: Jennifer Hamilton, Banu Subramaniam, and Angela Willey explore how two instances of population genetic research illustrate the racialized knowledge systems that undergirded colonialism, while Sandra Harding points out how the colonization of Latin America contributed to the edifice of Western science. In a related vein, Breny Mendoza centers the material role of Abya Yala (the preferred term for Latin America) in not just Spanish colonialism but British colonial expansionism and eventually the eclipsing of China. Patricia A. Schechter reflects on her trajectory as a scholar and teacher of US women’s history and the insights she has gained through 504Preface engaging decolonial scholarship. Amy Piedalue and Susmita Rishi argue for a more expansive understanding of postcolonial feminism’s reach as they review recently published titles in the field. Although Anna Tsing and Paulla Ebron’s review of feminist scholarship about the Anthropocene does not directly mention postcolonial or decolonial approaches, it nonetheless engages relevant scholarship on the environmental impact of settler modernization and capitalism. An art essay by Hyunji Kwon introduces the largely unrecognized paintings of former comfort woman Duk-kyung Kang (1929–1997) and focuses on the potential of Kang’s work to challenge Japanese colonial hierarchies. Our featured poets in this issue are Emily Zhang, Megan Kaminski, and Raina J. León. Both postcolonial and decolonial scholars have been committed to critiquing the material and epistemic legacies of colonialism. The distinctions that are frequently drawn between the two approaches, however, have been a source of disquiet to the editors of Feminist Studies, and they prompted our journal’s call for papers in 2016. A common temporal marking that concerned us was the eclipsing of postcolonialism, which was increasingly becoming viewed as passé, and a setting up of decolonial feminism as always already better in time. Decolonial approaches sometimes depicted postcolonial feminism as being only about the past, despite postcolonial feminism’s stated commitment to studying the continuing impact of colonial processes and its complex use of the prefix “post.” Our concern was, as well, with misrepresentations of postcolonial feminist priorities. The depiction of postcolonial feminism as deconstructive, abstract, elite theory confined to the ambit of modern colonial knowledge systems overlooked the important quandaries that postcolonial feminism raised about how to represent marginalized people ethically and, indeed, how to understand the very desire to represent the marginalized—whether or not we claim belonging to them. Postcolonial feminists warned against an easy embrace of alterity, noting that the desire for positioning oneself outside colonialism could naively ignore the power of colonial discourses to frame colonialism’s Other. Another set of hopes for this special issue was to dwell on the spatial markings of decolonial and postcolonial feminisms: decolonial feminism is often associated with Indigenous scholars and those from the Americas, and postcolonial feminism with scholars from South Asia, Africa, and the Middle East. These regional emphases, although not always as tidy as sometimes depicted, have produced distinct intellectual Preface 505 priorities. We must heed decolonial feminism’s insistence on engaging with the genocidal history of settler colonialism, the current manifestations of the violent dispossession of land, and its constitution of gendered racial capitalism the world over. (FeministStudies will soon publish a special issue on Indigenous Feminisms). Yet, if postcolonial feminism is circumscribed geographically to only South Asia, Africa, and the Middle East, we risk ignoring its powerful transcontinental mapping of imperial gender formations and its scrupulous attention to the ethics of representing...

The incorporation of hybrid systems based on renewable sources for the optimization of electricity distribution systems and planning of power supply strategies using genetic algorithms is studied. A series of characteristics of electrical sub-stations was chosen and through simulations, data were obtained for the optimization of the existing infrastructure, which provides reliability, security, economic supply and quality of service. An algorithm was obtained with the optimal configuration of various components: photovoltaic panels, batteries, AC generator, fuel cell and inverter, which in (...) the case of mono-objective optimization, minimized total system costs throughout its useful life. The most appropriate control strategy or combination of control variables was obtained to minimize costs. Keywords: Electrical distribution, Hybrid systems, Genetic algorithms. References [1]D. F.

This qualitative research study, a replication of a study published in 2002, investigated the qualities of a good nurse and the role ethics plays in decision making. After reviewing the limitations of the published work, the current study implemented modifications related to the research questions, sample selection, data collection, and use of software for data analysis. The original study identified seven categories that related to being a good nurse and doing the right thing. In the present study, the use of (...) relational analysis led to the recognition of four categories: (1) personal traits and attributes; (2) technical skills and management of care; (3) work environment and co-workers; and (4) caring and caring behaviors. To understand what it means to be a good nurse and do the right thing is a complex task; however, this research adds to the small amount of empirical data that exists to describe those characteristics.

R.I.G. Hughes presents a series of eight philosophical essays on the theoretical practices of physics. The first two essays examine these practices as they appear in physicists' treatises and journal articles. By treating these publications as texts, Hughes casts the philosopher of science in the role of critic. This premise guides the following six essays which deal with various concerns of philosophy and physics such as laws, disunities, models and representation, computer simulation, explanation, and the discourse of physics.

A thermal-mechanical analysis of the behavior of the segments of the rollers of the briquetting machines is carried out due to the effect of thermal shock and efforts exerted on the part. It is intended to obtain the main causes that generate this problem, through a mechanical analysis that simulated the behavior in the presence of several thermal gradients. The purpose of the study is to reduce maintenance costs and the continuous replacement and repair of segments, as well as losses (...) in tons of production due to the failure that are of great impact to the industry. This investigation allows us to know to what extent the operating parameters, such as: material temperature, pressure, torque, speed of the rollers influence the life of the segments according to their manufacturing material and based on these the behavior is simulated during the briquetting process.

The lively debate over the constitutional foundations of judicial review has been marred by a formalism which obscures its point and value.ed from genuine issues of substance, the rival positions offer inadequate accounts of the legitimacy of judicial review; constitutional theory must regain its connection with questions of political principle and moral value. Although the critics of ultra vires have rightly emphasized the foundational role of the common law, they have misconceived its nature and implications. On the one hand, they (...) have invited the charge of judicial supremacism by marginalizing the role of legislative intent; on the other, their affirmation of absolute parliamentary sovereignty (within the context of this debate) undermines the critique of ultra vires. In substance, therefore, the rival camps occupy essentially the same ground, equally trapped by a formalism that entrenches a stark confrontation between parliamentary sovereignty and the rule of law. A conception of shared sovereignty, or interdependent sovereignties, provides a better foundation for judicial review. (shrink)

BLWith new text and full apparatus criticus The Eudemian Ethics was one of two ethical treatises which Aristotle wrote on the subject of ethica or `matters to do with character'. Although the two works cover much the same ground, the Nicomachean Ethics is better known; the poor manuscript tradition of the Eudemian Ethics has made correct translation and interpretation of the text extremely difficult. The subject of the work is the choice of a certain means of conduct, made by a (...) `man of practical wisdom', between two extremes of behaviour: asceticism and yielding to uncontrolled impulses. Aristotle also stresses the notion of moral intention and the importance of virtue of character. This new Oxford Classical Text of the Eudemian Ethics is the result of many years of work. After Sir David Ross's death, his original text was substantially reworked and revised by his friend and colleague R. R. Walzer, who was aided in the revision by his former pupil Mrs Jean Mingay, who continued his work after his death in 1974. Mrs Mingay was fortunate in being able to make use of previously unpublished contributions from D. J. Allan after his death in the late seventies, and more recently has been helped in her work by the suggestions of Professor D. A. Russell, David Robinson, and Christopher Rowe. (shrink)

What kind of knowledge is medical knowledge? Can medicine be explained scientifically? Is disease a scientific concept, or do explanations of disease depend on values? What is ‘evidence-based’ medicine? Are advances in neuroscience bringing us closer to a scientific understanding of the mind? The nature of medicine raises fundamental questions about explanation, causation, knowledge and ontology – questions that are central to philosophy as well as medicine. In this book Paul R. Thompson and Ross E. G. Upshur introduce the fundamental (...) issues in philosophy of medicine for those coming to the subject for the first time. They introduce and explain the following key topics: Understanding the physician-patient relationship: the phenomenology of the medical encounter. Models and theories in biology and medicine: what role do theories play in medicine? Are they similar to scientific theories? Randomised controlled trials: can scientific experiments be replicated in clinical medicine? What are the philosophical criticisms levelled at RCTs? The concept of evidence in medical research: what do we mean by ‘Evidence-based medicine?’ Should all medicine be based on evidence? Causation in medicine What do advances in neuroscience reveal about the relationship between mind and body? Defining health and disease: are explanations of disease objective or do they depend on values? Evolutionary medicine: what is the role of evolutionary biology in understanding medicine? Is it relevant? Extensive use of empirical examples and case studies is made throughout the book. These include debates about smoking and cancer, the use of placebos in randomised controlled trials and controversies about research into the causes of HIV and autism. This is an indispendable introduction to those teaching philosophy of medicine and philosophy of science. (shrink)

The social and environmental problems that we face at this tail end of twentieth-century progress require us to identify some cause, some spirit that transcends the petty limits of our time and place. It is easy to believe that there is no crisis. We have been told too often that the oceans will soon die, the air be poisonous, our energy reserves run dry; that the world will grow warmer, coastlands be flooded and the climate change; that plague, famine and (...) war will be the necessary checks on population growth. But here we are: sufficiently healthy and well-fed, connoisseurs of far-off catastrophe and horror movies, confident that something will turn up or that the prophecies of doom were only dreams. We are the descendants, after all, of creatures who did not despair, who hoped against hope that there would still be life tomorrow. We no more believe in the world's end than we believe that soldiers could break down the door and drag us off to torture and to death: we don't believe that they could even when we know that, somewhere altogether elsewhere, they did. Even if we can force ourselves to remember other ages, other lands or other classes, we are content enough. (shrink)

The exogenous cycles and population dynamics of the community at Penrith, Cumbria, England, have been studied (1557-1812) using aggregative analysis, family reconstitution and time series analysis. This community was living under marginal conditions for the first 200 years and the evidence presented is of a homeostatic regime where famine, malnutrition and epidemic disease acted to regulate the balance between resources and population size. This provides an ideal historic population for an investigation of the direct and indirect effects of malnutrition. Throughout (...) the period studied, a short wavelength oscillation in grain prices was apparently the major external factor that drove exogenous cycles in mortality, birth rate, and migration. In particular, the different responses of children to variations in food supply are emphasised; fluctuations in poor nutrition correlated significantly with the variations in mortality rates for infants (probably indirectly during pregnancy and directly during the first year of life) and for young children (via susceptibility to lethal infectious diseases). Migratory movements contributed to the maintenance of homeostasis in the population dynamics. A medium wavelength cycle in low winter temperatures was associated with a rise in adult mortality which, in turn, promoted an influx of migrants into this saturated habitat. A model incorporating these interacting associations between vital events and exogenous cycles is presented: grain prices were an important density-dependent factor and constituted the major component of the negative feedback of this population and drove the exogenous, short wavelength mortality cycles. Cycles of births and immigration provide a positive feedback for the build-up of susceptibles and the initiation of smallpox epidemics and increased population size. (shrink)

The most glamorous and even glorious moments in a legal system come when a high court recognizes an abstract principle involving, for example, human liberty or equality. Indeed, Americans, and not a few non-Americans, have been greatly stirred--and divided--by the opinions of the Supreme Court, especially in the area of race relations, where the Court has tried to revolutionize American society. But these stirring decisions are aberrations, says Cass R. Sunstein, and perhaps thankfully so. In Legal Reasoning and Political Conflict, (...) Sunstein, one of America's best known commentators on our legal system, offers a bold, new thesis about how the law should work in America, arguing that the courts best enable people to live together, despite their diversity, by resolving particular cases without taking sides in broader, more abstract conflicts. Sunstein offers a close analysis of the way the law can mediate disputes in a diverse society, examining how the law works in practical terms, and showing that, to arrive at workable, practical solutions, judges must avoid broad, abstract reasoning. Why? For one thing, critics and adversaries who would never agree on fundamental ideals are often willing to accept the concrete details of a particular decision. Likewise, a plea bargain for someone caught exceeding the speed limit need not--indeed, must not--delve into sweeping issues of government regulation and personal liberty. Thus judges purposely limit the scope of their decisions to avoid reopening large-scale controversies. Sunstein calls such actions incompletely theorized agreements. In identifying them as the core feature of legal reasoning--and as a central part of constitutional thinking in America, South Africa, and Eastern Europe-- he takes issue with advocates of comprehensive theories and systemization, from Robert Bork to Jeremy Bentham, the father of utilitarianism, and Ronald Dworkin, who defends an ambitious role for courts in the elaboration of rights. Equally important, Sunstein goes on to argue that it is the living practice of the nation's citizens that truly makes law. For example, he cites Griswold v. Connecticut, a groundbreaking case in which the Supreme Court struck down Connecticut's restrictions on the use of contraceptives by married couples--a law that was no longer enforced by prosecutors. In overturning the legislation, the Court invoked the abstract right of privacy; the author asserts that the justices should have appealed to the narrower principle that citizens need not comply with laws that lack real enforcement. By avoiding large-scale issues and values, such a decision could have led to a different outcome in Bowers v. Hardwick, the decision that upheld Georgia's rarely prosecuted ban on sodomy. And by pointing to the need for flexibility over time and circumstances, Sunstein offers a novel understanding of the old ideal of the rule of law. Legal reasoning can seem impenetrable, mysterious, baroque. This book helps dissolve the mystery. Whether discussing the interpretation of the Constitution or the spell cast by the revolutionary Warren Court, Cass Sunstein writes with grace and power, offering a striking and original vision of the role of the law in a diverse society. In his flexible, practical approach to legal reasoning, he moves the debate over fundamental values and principles out of the courts and back to its rightful place in a democratic state: the legislatures elected by the people.

This distinction has sometimes been read as purely epistemic, resting not on things, but on our knowledge of them: there is one world, not two, though it may be apprehended in two ways. But this view is patently at odds with the text. Knowledge and opinion are δυνάμεις, "faculties," to be distinguished and defined by their objects, no less than by the state of mind they produce, and Plato clearly states that the fallibility and unclearness of opinion is rooted in (...) the relative unreality of opinables.
