Bringing together the expertise of rhetoricians in English and communication as well as media studies scholars, Arguments about Animal Ethics delves into the rhetorical and discursive practices of participants in controversies over the use of nonhuman animals for meat, entertainment, fur, and vivisection. Both sides of the debate are carefully analyzed, as the contributors examine how stakeholders persuade or fail to persuade audiences about the ethics of animal rights or the value of using animals.

This article explores some of the roles of computer simulation in measurement. A model-based view of measurement is adopted and three types of measurement—direct, derived, and complex—are distinguished. It is argued that while computer simulations on their own are not measurement processes, in principle they can be embedded in direct, derived, and complex measurement practices in such a way that simulation results constitute measurement outcomes. Atmospheric data assimilation is then considered as a case study. This practice, which involves combining information (...) from conventional observations and simulation-based forecasts, is characterized as a complex measuring practice that is still under development. The case study reveals challenges that are likely to resurface in other measuring practices that embed computer simulation. It is also noted that some practices that embed simulation are difficult to classify; they suggest a fuzzy boundary between measurement and non-measurement. 1 Introduction2 A Contemporary View of Measurement3 Three Types of Measurement4 Can Computer Simulations Measure Real-World Target Systems?5 Case Study: Atmospheric Data Assimilation5.1 Why data assimilation?5.2 A complex measuring practice under development5.3 Epistemic iteration6 The Boundaries of Measurement7 Epistemology, Not Terminology.

We call attention to an underappreciated way in which non-epistemic values influence evidence evaluation in science. Our argument draws upon some well-known features of scientific modeling. We show that, when scientific models stand in for background knowledge in Bayesian and other probabilistic methods for evidence evaluation, conclusions can be influenced by the non-epistemic values that shaped the setting of priorities in model development. Moreover, it is often infeasible to correct for this influence. We further suggest that, while this value influence (...) is not particularly prone to the problem of wishful thinking, it could have problematic non-epistemic consequences in some cases. (shrink)

This article identifies conditions under which robust predictive modeling results have special epistemic significance---related to truth, confidence, and security---and considers whether those conditions hold in the context of present-day climate modeling. The findings are disappointing. When today’s climate models agree that an interesting hypothesis about future climate change is true, it cannot be inferred---via the arguments considered here anyway---that the hypothesis is likely to be true or that scientists’ confidence in the hypothesis should be significantly increased or that a claim (...) to have evidence for the hypothesis is now more secure.

Philosophers continue to debate both the actual and the ideal roles of values in science. Recently, Eric Winsberg has offered a novel, model-based challenge to those who argue that the internal workings of science can and should be kept free from the influence of social values. He contends that model-based assignments of probability to hypotheses about future climate change are unavoidably influenced by social values. I raise two objections to Winsberg’s argument, neither of which can wholly undermine its conclusion but (...) each of which suggests that his argument exaggerates the influence of social values on estimates of uncertainty in climate prediction. I then show how a more traditional challenge to the value-free ideal seems tailor-made for the climate context. (shrink)

Today’s most sophisticated simulation studies of future climate employ not just one climate model but a number of models. I explain why this “ensemble” approach has been adopted—namely, as a means of taking account of uncertainty—and why a comprehensive investigation of uncertainty remains elusive. I then defend a middle ground between two camps in an ongoing debate over the transformation of ensemble results into probabilistic predictions of climate change, highlighting requirements that I refer to as ownership, justification, and robustness.

David Hume and Adam Smith are usually, and understandably, seen as developing very similar sentimentalist accounts of moral thought and practice. As similar as Hume's and Smith's accounts of moral thought are, they differ in telling ways. This essay is an attempt primarily to get clear on the important differences. They are worth identifying and exploring, in part, because of the great extent to which Hume and Smith share not just an overall approach to moral theory but also a conception (...) of what the key components of an adequate account of moral thought will be. In the process, I hope to bring out the extent to which they both worked to make sense of the fact that we do not merely have affective reactions but also, importantly, make moral judgments.

After showing how Deborah Mayo’s error-statistical philosophy of science might be applied to address important questions about the evidential status of computer simulation results, I argue that an error-statistical perspective offers an interesting new way of thinking about computer simulation models and has the potential to significantly improve the practice of simulation model evaluation. Though intended primarily as a contribution to the epistemology of simulation, the analysis also serves to fill in details of Mayo’s epistemology of experiment.

In 1904, Norwegian physicist Vilhelm Bjerknes published what would become a landmark paper in the history of meteorology. In that paper, he proposed that daily weather forecasts could be made by calculating later states of the atmosphere from an earlier state using the laws of hydrodynamics and thermodynamics (Bjerknes 1904). He outlined a set of differential equations to be solved and advocated the development of graphical and numerical solution methods, since analytic solution was out of the question. Using these theory-based (...) equations to produce daily forecasts, however, turned out to be more difficult than anticipated. Graphical solution techniques had limited success, and a first attempt to use .. (shrink)

This chapter identifies conditions under which robust predictive modeling results have special epistemic significance—related to truth, confidence, and security—and considers whether those conditions are met in the context of climate modeling today. The findings are disappointing. When today’s climate models agree that an interesting hypothesis about future climate change is true, it cannot be inferred, via the arguments considered here anyway, that the hypothesis is likely to be true, nor that confidence in the hypothesis should be significantly increased, nor that (...) a claim to have evidence for the hypothesis is now more secure. In some other modeling contexts, the prospects for such arguments are brighter. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 39.1 (2006) 45-71 [Access article in PDF] Presencing "Communion" in Chaïm Perelman's New Rhetoric Richard Graff Wendy Winn Department of RhetoricUniversity of MinnesotaOver the second half of his long and distinguished career, Chaïm Perelman reiterated the central themes of his theory of rhetoric many times. As the audience for his work expanded, Perelman was repeatedly invited to summarize the principles presented in La nouvelle rhétorique, (...) his magnum opus authored in collaboration with Lucie Olbrechts-Tyteca, which appeared in 1958. On these occasions, he would often attempt to clarify or refine the major concepts presented in that treatise. Nevertheless, even today many aspects of Perelman's work remain enigmatic. In outline, The New Rhetoric itself conveys a sense of structural and theoretical clarity, but for many readers this first impression evaporates when they confront the complexity and detail of the work's exposition. In the preface to their new study of Perelman, Alan Gross and Ray Dearin observe:The New Rhetoric is difficult to read, a task made even more difficult for American audiences because virtually all its examples and illustrations are from a literature in a foreign language.... Moreover, Perelman's later attempts to achieve clarity, in The Realm of Rhetoric, and numerous shorter articles, are equally puzzling. Consequently, some of Perelman's best ideas are virtually buried in a very long work, and therefore largely lost even to the most careful readers. In addition, on such central issues as the relationship between rhetoric and philosophy Perelman remains maddeningly obscure. (2003, ix) While Perelman's status as a pioneering figure in the rejuvenation of rhetorical study in Continental Europe is secure, as is his placement among the canonical twentieth-century theorists by American scholars, such difficulties constitute an impediment to contemporary understanding and future appreciation of his achievement; and the sprawling character of The New Rhetoric certainly has not helped to counteract the less [End Page 45] sympathetic reception his work has received in some corners of rhetorical and argumentation studies.1Gross and Dearin's volume joins several other recent studies that have contributed to the untangling of Perelman's thought and to the profitable application of his ideas.2 Still, some of Perelman's "best ideas" remain buried and sorely in need of excavation. Chief among these are considerations prompted by Perelman's use of the evocative yet mysterious term "communion." Although communion appears repeatedly among the panoply of concepts and argumentative techniques described in The New Rhetoric, explicit discussion of it there is brief and scattered, and the subject receives only glancing mention in Perelman's subsequent publications. In turn, communion has been all but ignored in the scholarship responding to or extending Perelman's work.3 This is even the case in studies where one would expect to see more serious engagement with Perelman's ideas on the subject—notably, in those that consider the status of values in argumentation and the role of rhetoric in the constitution and maintenance of community.4In this essay, we offer a detailed analysis of Perelman's conception of communion and, in the course of endowing the concept with greater "presence," aim to show its rich implications for these areas of inquiry. We argue that the idea of communion is a vital, if understated, component of Perelman's proposed "new rhetoric." Like other aspects of Perelman's theory, however, it is an expansive and somewhat slippery notion. In The New Rhetoric, communion is used in a very general sense as the term denoting a community's agreement on questions of value, but also, more narrowly, as an objective sought in certain forms of discourse and as an effect of specific linguistic-stylistic devices. The exegesis needed to indicate the subtle links between these senses will enable us to describe the manner in which Perelman endeavored to integrate the technical lore inherited from the classical tradition of rhetoric with a broadly social and determinedly pluralisticconception of argumentation.We begin by examining communion in relation to Perelman and Olbrechts-Tyteca's ideas...

In 2000, the Center for Disease Control and Prevention’s National Center for Environmental Health issued a report that explored some of the ways in which “sprawl” impacts public health. The report has generated great interest, and state health officials are beginning to discuss the relationship between land use and public health. The CDC report has also produced a backlash. For example, the Southern California Building Industry Association labeled the report “a ludicrous sham” and argued that the CDC should stick to (...) “fighting physical diseases, not defending political ones.”In retrospect, it is probably unfortunate that this report was funded by an organization called “Sprawl Watch.” “Spraw” is a word that has no clear meaning but is applied to a huge range of issues involving suburban development.

The most remarkable thing about the U.S. Supreme Court's 1998 decision in Bragdon v. Abbott was that it was necessary at all. Seventeen years into the epidemic of the acquired immunodeficiency syndrome, the Supreme Court, by a mere 5-4 majority, finally affirmed what most public health officials, health providers, and lawyers working with people with human immunodeficiency virus believed all along: that individuals with HIV infection are entitled to the protections of antidiscrimination law, and that health care providers must respond (...) to a patient's infection based on reason and science, not fear and prejudice. For individuals with HIV, and for those with other disabilities, the Court's ruling was a critical victory. But the very fact that the issues had to be decided by the Supreme Court and that only five justices joined the majority, shows the fragility of legal rights pertaining to HIV as well as the wide gulf between the perspectives of public health and those of public law.

Public health professionals recognize the critical role the law plays in determining the success of public health measures. Even before September 11, 2001, public health experience with tobacco use, HIV, industrial pollution and other potent threats to the health of the public demonstrated that laws can assist or thwart public health efforts. The new focus on infectious threats and bioterrorism, starting with the anthrax attacks through the mail and continuing with SARS, has highlighted the important role of law.For lawyers to (...) serve as effective partners in public health, they should have a basic familiarity with public health: how public health professionals see the world and the key issues they tackle. A practical grasp of public health can be acquired, and often is acquired, “on the job.”. (shrink)

This article examines feminist agency in the light of Merleau-Ponty’s phenomenological account of the body subject. Stressing the importance of embodiment to feminist agency (without reifying an essential female body), I argue that bodies inhabit specific social, historical and discursive contexts which shape our corporeal experience and our opportunities for political contestation. Beginning with the assertion that we cannot think of agency without the body, I examine a historical instance of feminist agency in which women’s bodies were central to the (...) articulation of political dissent, namely the British suffragette movement. In particular, I focus on the suffragette career of Mary Leigh and argue that it represents a feminist agency derived from corporeal performance. Through daring acts of protest which drew attention to the comportment and capacities of their bodies, suffragettes like Leigh contested the constitution of the political domain and the nature of citizenship.

How does emigration affect access to and struggles for power in sending states? For competing groups in the homeland, emigration presents a contradiction: demographic losses but possible economic gains. Wins and losses from this trade-off evolve with shifts in who migrates, to where, and when. I illustrate these relationships in the case of Lebanon since 1860, focusing on the balance of power among sectarian communities. The country’s first migratory wave concentrated material benefits and population deficits in the Christian community. It (...) also encouraged subsequent emigration that, over time, involved more Muslim Lebanese, as well. Such broadening diffused the profits of labor abroad. Due to changes in destinations and historical circumstances, however, many of these migrants remained more connected to their homeland. This aided social mobility for their communities without sapping resident strength. Outmigration thereby helped redistribute human and material resources among sects, and hence created the demographic and material foundations of the competition for power. (shrink)

A narrative history of Notre Dame's world renowned philosophy department, which divides the nearly 80 decades into three distinct periods: textbook Thomism, pluralism, and professionalism.

Plato’s method of hypothesis is initiated in the Meno, is featured in the Phaedo and the Republic, and is further developed in the Theaetetus. His method of collection and division is mentioned in the Republic, is featured in the Phaedrus,and is elaborated with modifications in the Sophist and the Statesman. Both methods aim at definitions in terms of necessary and sufficient conditions. In the course of these developments, the former method is shown to be weak in its treatment of sufficient (...) conditions, and the latter is shown to be comparably weak in its treatment of necessary conditions. A third method, which avoids these difficulties, is introduced in the first part of the Parmenides and is applied in connection with the eight hypotheses that follow. This application yields a demonstration of serious shortcomings both in historical Eleaticism and in the Eleatically-inspired theory of Forms in the Phaedo and the Republic, along with a demonstration of comparative strengths in historical Pythagoreanism and in the Pythagorean- inspiried theory of Forms in the Statesman and the Philebus.
