It is commonly thought that disability is a harm or “bad difference” because having a disability restricts valuable options in life. In his recent essay “Disability, Options and Well-Being,” Thomas Crawley offers a novel defense of this style of reasoning and argues that we and like-minded critics of this brand of argument are guilty of an inconsistency. Our aim in this article is to explain why our view avoids inconsistency, to challenge Crawley's positive defense of the Options Argument, and (...) to suggest that this general line of reasoning employs a double standard.

Early last year, the GenEthics Consortium (GEC) of the Washington Metropolitan Area convened at George Washington University to consider a complex case about genetic testing for Alzheimer disease (AD). The GEC consists of scientists, bioethicists, lawyers, genetic counselors, and consumers from a variety of institutions and affiliations. Four of the 8 co-authors of this paper delivered presentations on the case. Supplemented by additional ethical and legal observations, these presentations form the basis for the following discussion.

This study provides a comparative analysis of students' self-reported beliefs and behaviors related to six analogous pairs of conventional and digital forms of academic cheating. Results from an online survey of undergraduates at two universities (N = 1,305) suggest that students use conventional means more often than digital means to copy homework, collaborate when it is not permitted, and copy from others during an exam. However, engagement in digital plagiarism (cutting and pasting from the Internet) has surpassed conventional plagiarism. Students (...) also reported using digital "cheat sheets" (i.e., notes stored in a digital device) to cheat on tests more often than conventional "cheat sheets." Overall, 32% of students reported no cheating of any kind, 18.2% reported using only conventional methods, 4.2% reported using only digital methods, and 45.6% reported using both conventional and digital methods to cheat. "Digital only" cheaters were less likely than "conventional only" cheaters to report assignment cheating, but the former was more likely than the latter to report engagement in plagiarism. Students who cheated both conventionally and digitally were significantly different from the other three groups in terms of their self-reported engagement in all three types of cheating behavior. Students in this "both" group also had the lowest sense of moral responsibility to refrain from cheating and the greatest tendency to neutralize that responsibility. The scientific and educational implications of these findings are discussed in this study. (shrink)

> Wealthy nations must do much more, much faster. The United Nations General Assembly in September 2021 will bring countries together at a critical time for marshalling collective action to tackle the global environmental crisis. They will meet again at the biodiversity summit in Kunming, China, and the climate conference 26) in Glasgow, UK. Ahead of these pivotal meetings, we—the editors of health journals worldwide—call for urgent action to keep average global temperature increases below 1.5°C, halt the destruction of nature (...) and protect health. Health is already being harmed by global temperature increases and the destruction of the natural world, a state of affairs health professionals have been bringing attention to for decades.1 The science is unequivocal; a global increase of 1.5°C above the preindustrial average and the continued loss of biodiversity risk catastrophic harm to health that will be impossible to reverse.2 3 Despite the world’s necessary preoccupation with COVID-19, we cannot wait for the pandemic to pass to rapidly reduce emissions. Reflecting the severity of the moment, this editorial appears in health journals across the world. We are united in recognising that only fundamental and equitable changes to societies will reverse our current trajectory. The risks to health of increases above 1.5°C are now well established.2 Indeed, no temperature rise is ‘safe’. In the past 20 years, heat-related mortality among people aged over 65 has increased by more than 50%.4 Higher temperatures have brought increased dehydration and renal function loss, dermatological malignancies, tropical infections, adverse mental health outcomes, pregnancy complications, allergies, and cardiovascular and pulmonary morbidity and mortality.5 6 Harms disproportionately affect the most vulnerable, including children, older populations, ethnic minorities, poorer communities and those with underlying health problems.2 4 Global heating is also contributing to the decline in ….

This rich and varied collection of essays addresses some of the most fundamental human questions through the lenses of philosophy, literature, religion, politics, and theology. Peter Augustine Lawler and Dale McConkey have fashioned an interdisciplinary consideration of such perennial and enduring issues as the relationship between nature and history, nature and grace, reason and revelation, classical philosophy and Christianity, modernity and postmodernity, repentance and self-limitation, and philosophy and politics.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey, which is part of the Sloan Digital Sky Survey III. Our results come from the Data Release 11 sample, containing nearly one million galaxies and covering approximately 8500 square degrees and the redshift range 0.2 < z < 0.7. We also compare these results with those from the publicly released (...) DR9 and DR10 samples. Assuming a concordance Λ cold dark matter cosmological model, the DR11 sample covers a volume of 13 Gpc3 and is the largest region of the Universe ever surveyed at this density. We measure the correlation function and power spectrum, including density-field reconstruction of the BAO feature. The acoustic features are detected at a significance of over 7σ in both the correlation function and power spectrum. Fitting for the position of the acoustic features measures the distance relative to the sound horizon at the drag epoch, rd, which has a value of rd,fid = 149.28 Mpc in our fiducial cosmology. We find DV = at z = 0.32 and DV = at z = 0.57. At 1.0 per cent, this latter measure is the most precise distance constraint ever obtained from a galaxy survey. Separating the clustering along and transverse to the line of sight yields measurements at z = 0.57 of DA = and H =. Our measurements of the distance scale are in good agreement with previous BAO measurements and with the predictions from cosmic microwave background data for a spatially flat CDM model with a cosmological constant. © 2014 The Author Published by Oxford University Press on behalf of the Royal Astronomical Society.

We evaluated the reliability, validity, and differential item functioning (DIF) of a shorter version of the Defining Issues Test-1 (DIT-1), the behavioral DIT (bDIT), measuring the development of moral reasoning. 353 college students (81 males, 271 females, 1 not reported; age M = 18.64 years, SD = 1.20 years) who were taking introductory psychology classes at a public University in a suburb area in the Southern United States participated in the present study. First, we examined the reliability of the bDIT (...) using Cronbach’s α and its concurrent validity with the original DIT-1 using disattenuated correlation. Second, we compared the test duration between the two measures. Third, we tested the DIF of each question between males and females. Findings reported that first, the bDIT showed acceptable reliability and good concurrent validity. Second, the test duration could be significantly shortened by employing the bDIT. Third, DIF results indicated that the bDIT items did not favour any gender. Practical implications of the present study based on the reported findings are discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 40.1 (2002) 119-121 [Access article in PDF] Book Review Ethics and Political Philosophy The Common Good in Late Medieval Political Thought Arthur Stephen McGrade, John Kilcullen, and Matthew Kempshall, editors.

Kempshall. The (...) Common Good in Late Medieval Political Thought. New York: Oxford University Press, 1999. Pp. x + 401. Cloth, $95.00. With the exception of the thought of Thomas Aquinas and John Duns Scotus, late medieval political and ethical philosophy has been neglected. Two recent books attempt to rectify this neglect. One is the second volume of The Cambridge Translations of Medieval Philosophical Texts. A translator of this volume, Matthew Kempshall, has also recently written a thorough analysis of the common good as it is discussed in late thirteenth-century scholasticism. Many of the texts discussed in this second book are translated by Kempshall in the first book.The new volume of translations now makes it possible for the reader unfamiliar with Latin to have some exposure to the medieval reception of Aristotle's ethical and political thought. The selections are deliberately taken from lesser-known figures who are not often translated, such as Albert the Great, Godfrey of Fontaines, and Augustine of Ancona. The selections are carefully chosen to represent a wide variety of literary genres. For example, the selection from Albert is part of his commentary of Book X of the Nicomachean Ethics, [End Page 119] whereas the selection from Godfrey is a Quodlibetal Question, and that from Augustine of Ancona is part of a treatise. Moreover, there are some selections that show developments within a particular genre. For example, a translation from Buridan's commentary on Book X of the Nicomachean Ethics contrasts nicely with that of Albert. The selection from Albert focuses mostly on pleasure, the relationship between the active and the contemplative lives, and the connection between ethics and politics. His discussion of pleasure is philosophically important in light of twentieth-century discussions about reasons for actions. Moreover, these issues are all discussed in at least one of the other selections. Interestingly, Buridan's commentary on the same Book focuses instead on human freedom. Buridan makes fine distinctions that are relevant to contemporary debates about free will. Selections from Henry of Ghent, Godfrey of Fontaines, and James of Viterbo all address the topic of the relationship between self-love and the virtuous life. These passages are relevant to the question of whether there is egoism in ancient and medieval ethical thought.The volume is a companion to The Cambridge History of Later Medieval Philosophy and suffers from one of its weaknesses, which is that the selections can seem arbitrary. For example, the passage from Albert takes up nearly one quarter of the volume. Furthermore, sometimes the representation of an author by only one genre is misleading. For example, although Giles of Rome wrote a Quodlibetal Question (Quod 2, q. 20) that is directly attacked in a translation from James of Viterbo, Giles is represented only by a passage from his treatise De regimine principum. Moreover, the moral psychology of the late thirteenth century is not well-covered, which is odd considering the importance of Bonnie Kent's work in this area.One additional problem is that there are few notes to aid the reader. Sometimes the translations can be confusing. For example, in one passage "the Commentator" should be identified, since the name can apply to at least three individuals (262-3). More seriously, readers with little background in medieval thought might confuse the medieval referents signified in the translation by the words "state" or "love" with contemporary referents. The translations themselves are clear and the different translators follow a consistent set of guidelines. Anyone who tries to translate some of these passages for herself will understand that some... (shrink)

Meeting of the Minds records the proceedings of the S.I.E.P.M. conference held in Boston from June 14-16, 1996. The conference participants centred their attention on the relationships between medieval and classical modern philosophy. These relationships have been painted in dramatically different ways by those who have presented overviews of the two eras. Hans Blumenberg, in The Legitimacy of the Modern Age and his subsequent works, discovers the seeds of modernity in the medieval authors themselves. Leo Strauss and his followers see (...) a radical difference between the classical world views of the ancients and medievals and the successive layers of modern thought. These general portraits demand specifics, and the strength of the conference, whose results are contained in this volume, was that it provided many specific examinations of concrete relations between the philosophical positions of celebrated medieval and modern thinkers. Our hope is that this collection of papers will suggest the direction for further cooperative efforts on the interplay of the philosophical views represented by these two eras, and that the issues commonly debated by the medieval and early modern thinkers represented in this volume will give renewed consideration to important philosophical points that have been ignored in more recent debates. The volume contains contributions from E.

This book explores the overlooked but vital theoretical relationships between R. M. Hare, Alan Gewirth, and Jürgen Habermas. The author claims their accounts of value, while failing to address classic virtue-theoretical critiques, bear the seeds of a resolution to the ultimate question "What is most valuable?" These dialectical approaches, as claimed, justify a reinterpretation of value and value judgment according to the Carnapian conception of an empirical-linguistic framework or grammar. Through a further synthesis with the work of Philippa Foot and (...) Thomas Magnell, the author shows that "value" would be literally meaningless without four fundamental phenomena which constitute such a framework: Logical Judgment, Conceptual Synthesis, Conceptual Abstraction, and Freedom. As part of the 'grammar of goodness,' the excellence of these phenomena, in a highly concrete way, constitute the essence of the greatest good, as this book explains.. (shrink)

While the opposing paradigms of globalization and fragmentation compete in often bloody and destructive ways in the world today, this book convincingly reminds us of the importance of finding out more about the complex and changing ways in which we are connected. The authors demonstrate that the more we understand our connectedness and deal with its consequences, the less dependent and helpless we become. The critical, multidisciplinary perspectives they offer cover a wide range of subjects, from the world wide web (...) to medieval poetry, nations and gender, cancer narratives and money, emotion management and the financial markets, and the American civilizing process and the repression of shame. The contributions bear witness to Elias's innovative achievements while the authors continue his stunning explorations, extending them into other areas of the humanities and the sciences, and presenting their own wide-ranging and penetrating insights into our mutual dependence. Contributors are Jorge Arditi, Godfried Van Benthem Van Den Bergh, Reinhard Blomert, Stephen Guy-Bray, Thomas M. Kemple, Hermann Korte, Helmut Kuzmics, Stephen Mennell, Thomas Salumets, Thomas J.

The Unfinished Revolution compares the post-Second World War histories of the American and British gay and lesbian movements with an eye toward understanding how distinct political institutional environments affect the development, strategies, goals, and outcomes of a social movement. Stephen M. Engel utilizes an electic mix of source materials ranging from the theories of Mancur Olson and Michel Foucault to Supreme Court rulings and film and television dialogue. The two case study chapters function as brief historical sketches to elucidate (...) further the conclusions on theory and whilst being politically-oriented, they also examine gay influence and expansion into mainstream popular culture. The book also includes an appendix that surveys and assesses the analytical potential of five critical understandings of social movements: the classical approach, rational choice, resource mobilization, new social movement theories, and political opportunity structures. It will be of value to academics and students of sociology, political science, and history. (shrink)

On the traditional view, moral distress arises only in cases where an individual believes she knows the morally right thing to do but fails to perform that action due to various constraints. We seek to motivate a broader understanding of moral distress. We begin by presenting six types of distress that fall outside the bounds of the traditional definition and explaining why they should be recognized as forms of moral distress. We then propose and defend a new and more expansive (...) definition of moral distress and examine how it can enable the development of a taxonomy of moral distress. (shrink)

It is widely assumed that disability is typically a bad thing for those who are disabled. Our purpose in this essay is to critique this view and defend a more nuanced picture of the relationship between disability and well-being. We first examine four interpretations of the above view and argue that it is false on each interpretation. We then ask whether disability is thereby a neutral trait. Our view is that most disabilities are neutral in one sense, though we cannot (...) make simple generalizations about disability's relationship to well-being in other important senses. After defending this view, we discuss its practical implications for selective abortion for disability, nondisabled people's interactions with disabled people, and the use of QALYs in health policy.

In the first part, we sketch four theories of anti-meaning that correspond to leading theories of meaning. In the second part, we argue that anti-meaning has significance not only for our attempts to (...) theorize about meaning in life, but also for our ability to lead meaningful lives in the modern world.

Disability and enhancement are often treated as opposing concepts. To become disabled in some respect is to move away from those who are enhanced in that same respect; to become enhanced is to move away from the corresponding state of disability. This chapter examines how best to understand the concepts of disability and enhancement in this symmetrical way. After considering various candidates, two types of accounts are identified as the most promising: welfarist accounts and typical-functioning accounts. The authors ultimately defend (...) a complex typical-functioning account as the best way to achieve a symmetrical understanding of disability and enhancement. (shrink)

The so-called Disability Paradox arises from the apparent tension between the popular view that disability leads to low well-being and the relatively high life-satisfaction reports of disabled people. Our aim in this essay is to make some progress toward dissolving this alleged paradox by exploring the relationship between disability and various “goods of life”—that is, components of a life that typically make a person’s life go better for her. We focus on four widely recognized goods of life (happiness, rewarding relationships, (...) knowledge, achievement) and four common types of disability (sensory, mobility, intellectual, and social) and systematically examine the extent to which the four disability types are in principle compatible with obtaining the four goods of life. Our findings suggest that that there is a high degree of compatibility. This undermines the widespread view that disabilities, by their very nature, substantially limit a person’s ability to access the goods of life, and it provides some guidance on how to dissolve the Disability Paradox.

Climate change is a global problem that is predominantly an intergenerational conflict, and which takes place in a setting where our ethical impulses are weak. This "perfect moral storm" poses a profound challenge to humanity. This book explains how the "perfect storm" metaphor makes sense of our current malaise, and why a better ethics can help see our way out.

This book addresses what it means to teach and learn ethics. While teaching ethics is universally applauded, how one goes about it is much more difficult and contested than is often recognized. The approach of the work is historical, philosophical, and theological. It begins with the historical transformation in the mid nineteenth century by Henry Sidgwick, who rejected establishing ethics on theology or metaphysics. G. E. Moore, John Rawls, Thomas Hurka, Bart Schultz, and Peter Singer later explicitly developed ethics (...) indebted to Sidgwick. However, G. E. M. Anscombe and Philippa Foot's important interventions in modern moral philosophy opened new possibilities for teaching and learning ethics that bear strong resemblances to pre-Sidgwick moral philosophy. The common thread between them is Thomas Aquinas, who had a different understanding of human action than Sidgwick. For Aquinas, Foot, and Anscombe, ethics does not concern a procedure to guide action to what is right or what ought to be, but exists within a metaphysical and theological realm in which the good is more basic than the right. The good is attractive so desire for it is an essential element of the moral life. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume 29, Number 2, November 2003, pp. 223-266 A Diplomatic Transcription of Hume's "volunteer pamphlet" for Archibald Stewart: Political Whigs, Religious Whigs, and Jacobites M. A. BOX, DAVID HARVEY, AND MICHAEL SILVERTHORNE Many scholars interested in David Hume will have encountered his defense of the beleaguered Archibald Stewart as it appears in an appendix in John Valdimir Price's The Ironic Hume (Austin: University of Texas Press, 1965). (...) Additionally they might know of Price's discussion for The Biblioteck of 1973 of a copy with manuscript markings. A reason for revisiting this pamphlet is that the National Library of Scotland has graciously given permission to reproduce a copy (shelfmark NE.10.e.4) featuring a preface and significant markings in manuscript not in the copy that Price reproduced in his book. As Hume assumes considerable familiarity with the events to which he alludes, we have annotated the text to make it fully intelligible to readers two and half centuries after its composition. The rudimentary bibliographic facts and mysteries are as follows. Two editions survive to us, an octavo (in fours) and a rare duodecimo. Although there is no reason to regard the duodecimo as a second edition correcting or augmenting a first edition, it probably was manufactured after, and was textually derivative from, the octavo. We know nothing of the publishing of M. A. Box is Associate Professor of English, University of Alaska, Fairbanks, PO Box 755720, Fairbanks, AK 99775-5720, USA. David Harvey is at the Classics Department, University of Exeter, Queen's Building, Queen's Drive, Exeter EX4 4QH, UK.

Box, David Harvey, and Michael Silverthorne the duodecimo, and doubtless that is as its producers intended. Its title page indicates, like that of the octavo, that the printing was done "for M. Cooper" in 1748, but William Strahan's ledgers register the printing in December 1747 of only the octavo in an edition of 1000 copies.1 The job is listed under bookseller Andrew Millar's account, not Mary Cooper's, probably for the reason that Cooper was a front whose role was to screen the true producers. It is possible that Millar hired someone other than Strahan to print the duodecimo, but it is also possible that someone other than Millar had it printed to mimic the octavo and take the opportunity it offered for concealment.2 A different editorial judgment is evinced in the duodecimo in that cosmetic measures are taken in it to obscure the identities of two military men ridiculed. For example, "Fowke" is rendered as "F—" and "John Cope" as "J-C-----." A digression on Mary Cooper is in order. This remarkable woman (died 1761) took over her husband Thomas's business upon his death 9 February 1743. That business had a history of "publishing" pamphlets and therefore made a plausible front for Millar, who in at least thirty-six other instances, none requiring courage, was willing to have his name appear on a title page with "M. Cooper." (This figure derives from a search by imprints using the English Short-Title Catalogue.) Until Thomas Cooper died, his name appeared on editions of John Armstrong's The Oeconomy of Love (1736 and thereafter) though only Millar's name is listed in the Stationers' Register (Foxon, English Verse A303-A311), and Mary's name is on the title page of the 1753 edition for which Strahan charged Millar (Strahan Papers, Add. MS 48800, s.v. August 1753). It was perhaps in this pattern that the second edition of Hume's heterodox Philosophical Essays (1750) would be reissued in 1751 with a new title page replacing Millar's name with Cooper's. That book was made temporarily a more alarming property by the superstitious panic of the London populace following the winter earthquakes in 1750, presaged by a bloody cloud. Within that year Bishop Thomas Sherlock caused a stir with a pastoral letter (A Letter from the Lord Bishop of London) blaming the earthquakes on several iniquities, "particularly heretical books" (Walpole, Correspondence 20...

It seems better to have a life that begins poorly and ends well than a life that begins well and ends poorly. One possible explanation is that the very shape of a life can be good or bad for us. If so, this raises a tough question: when can the shape of our lives be good or bad for us? In this essay, I present and critique an argument that the shape of a life is a non-synchronic prudential value—that is, (...) something that can be good or bad for us in a way that is not good or bad for us at any particular time. After distinguishing two interpretations of ‘the shape of a life’, I argue that the first type of shape can be good or bad for us at particular moments while the other cannot be good or bad for us at all. This suggests that the shape of a life gives us no reason to posit non-synchronic prudential values. (shrink)

What might a theory of mental imagery look like, and how might one begin formulating such a theory? These are the central questions addressed in the present paper. The first section outlines the general research direction taken here and provides an overview of the empirical foundations of our theory of image representation and processing. Four issues are considered in succession, and the relevant results of experiments are presented and discussed. The second section begins with a discussion of the proper form (...) for a cognitive theory, and the distinction between a theory and a model is developed. Following this, the present theory and computer simulation model are introduced. This theory specifies the nature of the internal representations (data structures) and the processes that operate on them when one generates, inspects, or transforms mental images. In the third, concluding, section we consider three very different kinds of objections to the present research program, one hinging on the possibility of experimental artifacts in the data, and the others turning on metatheoretical commitments about the form of a cognitive theory. Finally, we discuss how one ought best to evaluate theories and models of the sort developed here. (shrink)

I critically examine the semantic view of theories to reveal the following results. First, models in science are not the same as models in mathematics, as holders of the semantic view claim. Second, when several examples of the semantic approach are examined in detail no common thread is found between them, except their close attention to the details of model building in each particular science. These results lead me to propose a deflationary semantic view, which is simply that model construction (...) is an important component of theorizing in science. This deflationary view is consistent with a naturalized approach to the philosophy of science. (shrink)

This paper describes an operational computer simulation of visual mental imagery in humans. The structure of the simulation was motivated by results of experiments on how people represent information in, and access information from, visual images. The simulation includes a “surface representation,” which is spatial and quasi‐pictorial, and an underlying “deep representation,” which contains “perceptual” information encoding appearance plus “propositional” information describing facts about an object. The simulation embodies a theory of how surface images are generated from deep representations, and (...) how surface images are processed when one accesses information embedded in them. The simulation also offers an account of various sorts of imagery transformations. (shrink)

Very few moral philosophers have written on climate change.1 This is puzzling, for several reasons. First, many politicians and policy makers claim that climate change is not only the most serious environmental problem currently facing the world, but also one of the most important international problems per se.2 Second, many of those working in other disciplines describe climate change as fundamentally an ethical issue.3.
