© 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)

In lieu of an abstract, here is a brief excerpt of the content:Hume Studies Volume XXVI, Number 1, April 2000, pp. 129-142 Hume on ''Greatness of Soul" GRAHAM SOLOMON The "great-souled man" was first described in detail in Book iv of Aristotle's Nicomachean Ethics. Simon Blackburn concisely summarizes Aristotle's portrait of this "lofty character": "The great-souled man is of a distinguished situation, worthy of great things, 'an extreme in respect of the greatness of his claims, but a mean in (...) respect of the Tightness of them', perfectly virtuous, good at conferring benefits but ashamed of receiving them, neither humble nor vain. The combination involves proper pride or magnanimity." Such men will enter politics with the aim of preserving justice and working for the good of society, or they will exhibit great personal courage in battle, or, more generally, they will aim at virtuous action at all times, even when faced with painful choices and life-threatening circumstances. Historians disagree about whether Aristotle held that the great-souled man is motivated in part by a desire to be admired by others, but certainly he held that the great-souled man was capable of performing great and virtuous actions that would be admired.1 By the mid-eighteenth century, greatness of soul could be found in much less distinguished situations. Consider, for example, Laurence Sterne's Tristram Shandy. Tristram attributes greatness of soul to his mother for wanting to give birth to him under the care of a midwife rather than a doctor. His father thinks that turning down a large purse of money offered in exchange for naming one's son Judas is an act of greatness of mind. And Tristram says his friend Jenny exhibited greatness of soul by purchasing a much less expensive piece of silk than the one she initially wanted, deferring to Tristram's unvoiced but Graham Solomon is at the Philosophy Department,Wilfrid Laurier University,Waterloo, Ontario, Canada N2L 3C5. e-mail: [email protected] 130 Graham Solomon obvious judgment.2 For an example from the nineteenth century, consider the following passage from the novel The Wrecker (1891) by Robert Louis Stevenson and Lloyd Osbourne. The narrator, a wealthy young American, is slumming as a bohemian art student in the Latin Quarter of Paris: "I always looked with awful envy... on a certain countryman of my own, who had a studio in the Rue Monsieur Ie Prince, wore boots, and long hair in a net, and could be seen tramping off, in this guise, to the worst eating-house of the quarter, followed by a Corsican model, his mistress, in the conspicuous costume of her race and calling. It takes some greatness of soul to carry even folly to such heights as these."3 There the character's greatness of soul seems to involve an ability to ignore or overlook or misinterpret the opinions others might have of him. While the phrase "greatness of soul" or "greatness of mind" is not commonly used nowadays,4 the Latin form "magnanimity" is still in use in ordinary, everyday, reasonably educated discourse. And occasionally "highmindedness " is used. The capacity to make magnanimous gestures is still widely felt to be a virtue. "Magnanimity" nowadays refers to a mix of unselfishness, generosity, the capacity to rise above petty feelings of resentment and revenge, and more generally and vaguely to a kind of nobility of heart and mind. These are features that Aristotle would recognize. But, it seems to me, we are prepared to apply the term to a far wider class of people than Aristotle would. Magnanimity is nowadays thought to be a virtue that can be exhibited by almost anyone. The first extended discussion in English-language philosophy of the concept of greatness of soul or mind is in David Hume's Treatise III iii 2, a section titled "Of greatness of mind." Hume's discussion contributed to a domesticated and democratized understanding of the concept, a more serious ancestor of the concept found in Tristram Shandy5 and The Wrecker. Donald Siebert argues in the chapter "In Search of the Hero of Feeling" in The Moral Animus of David Hume6 that after the initial exploration of the concept in the Treatise, Hume eventually settled in The History...

Disputing the Unity of the World: The Importance of Res and the Influence of Averroes in Giles of Rome's Critique of T homas Aquinas concerning the Unity of the World G. j. MCALEER 1. INTRODUCTION tILES OF ROME earned, after a decidedly difficult start, the most complete honors open to an academic religious in the Middle Ages. Joining the Hermits of St. Augustine at age 14, he became the first regent master of his order at the University of Paris ; (...) his works were made compul- sory in the education of students entering the Hermits in 1287; finally, in 1292 he became the general of the order itself.' Giles is significant, as Mandonnet puts it, because he "est incontestablement au premier rang des th~ologiens de la fin du XIII e si~cle. "2 But this is not all. Giles is also important to the period because his writings were censured by the same commission that composed the famous Parisian condemnation of 1277. As a result of this I would like to thank Robert Wielockx, Jos Decorte, Jennifer DeRose, and especially two anonymous referees of theJHP, for their extremely useful comments on an earlier draft of this paper.

'Justice' and 'democracy' have alternated as dominant themes in political philosophy over the last fifty years. Since its revival in the middle of the twentieth century, political philosophy has focused on first one and then the other of these two themes. Rarely, however, has it succeeded in holding them in joint focus. This volume brings together leading authors who consider the relationship between democracy and justice in a set of specially written chapters. The intrinsic justness of democracy is challenged, the (...) relationship between justice, democracy and impartiality queried and the relationship between justice, democracy and the common good examined. Further chapters explore the problem of social exclusion and issues surrounding sub-national groups in the context of democracy and justice. Authors include Keith Dowding, Richard Arneson, Norman Schofield, Albert Weale, Robert E. Goodin, Jon Elster, David Miller, Phillip Pettit, Julian LeGrand and Russell Hardin. (shrink)

abstract ‘Time is money’, Benjamin Franklin's ‘Poor Richard’ tells us. But instead of converting time expenditures into monetary equivalents, it makes more sense in many cases to convert money into temporal equivalents. The difficulty in putting a monetary value on time in unpaid household labour, when adjusting the National Accounts, points to the problems of the first approach. The advantages of the latter approach are illustrated by the Swedish system of specifying criminal fines in terms of the number of days (...) the offender would have to work to pay them off.

Bryan Norton 's convergence hypothesis, which predicts that nonanthropocentric and human-based philosophical positions will actually converge on long-sighted, multi-value environmental policy, has drawn a number of criticisms from within environmental philosophy. In particular, nonanthropocentric theorists like J. Baird Callicott and Laura Westra have rejected the accuracy of Norton 's thesis, refusing to believe that his model's contextual appeals to a plurality of human and environmental values will be able adequately to provide for the protection of ecological integrity. These theoretical criticisms (...) of convergence, however, have made no real attempt to engage the empirical validity of the hypothesis, the dimension that Norton clearly takes to be the centerpiece of his project. Accordingly, the present paper attempts to provide an empirical analysis of the convergence argument, by means of a study of the Vermont public's environmental commitments and their attitudes toward national forest policy. Our findings support a generalized version of Norton 's thesis, and lead us to suggest that environmental philosophers should try to be more inclusive and empirically minded in their discussions about public moral claims regarding nature.

This comprehensive anthology of Bertrand Russell's writings brings together his definitive essays from the period 1903 to 1959. It covers the most fertile and the most lasting work on every significant area he published in.

Climate engineering (CE), the intentional modification of the climate in order to reduce the effects of increasing greenhouse gas concentrations, is sometimes touted as a potential response to climate change. Increasing interest in the topic has led to proposals for empirical tests of hypothesized CE techniques, which raise serious ethical concerns. We propose three ethical guidelines for CE researchers, derived from the ethics literature on research with human and animal subjects, applicable in the event that CE research progresses beyond computer (...) modeling. The Principle of Respect requires that the scientific community secure the global public's consent, voiced through their governmental representatives, before beginning any empirical research. The Principle of Beneficence and Justice requires that researchers strive for a favorable risk–benefit ratio and a fair distribution of risks and anticipated benefits, all while protecting the basic rights of affected individuals. Finally, the Minimization Principle requires that researchers minimize the extent and intensity of each experiment by ensuring that no experiments last longer, cover a greater geographical extent, or have a greater impact on the climate, ecosystem, or human welfare than is necessary to test the specific hypotheses in question. Field experiments that might affect humans or ecosystems in significant ways should not proceed until a full discussion of the ethics of CE research occurs and appropriate institutions for regulating such experiments are established.

The ‘marketplace of ideas’ is an influential metaphor with widespread currency in debates about freedom of speech. We explore a number of ways competition between ideas might be described as occurring in a marketplace and find that none support the use of the metaphor. We suggest that an alternative metaphor, that of the ‘garden of ideas’, may offer more productive insights into issues surrounding the regulation of speech.

How does one measure whether a “Speculum” is of sufficiently broad interest to be worthy of an article in Speculum? I refer to Marguerite Porete's Mirror of Simple Souls, which I believe amply meets the test. Since the publication of the Middle French text of the Mirror in 1965, two translations have appeared in modern French, two in Italian, one in German, one in Spanish, and one in Catalan. Two translations are also available in English. Both have remained in print (...) since their initial appearance in the 1990s; one is owned by 576 libraries worldwide, and the other by 160, to which might be added 279 copies of an earlier English translation made from the Middle English version of the Mirror. A rough count of secondary works on Marguerite published in the last twenty-five years adds up to some one hundred books and articles. Quite intriguing is the diverse use made of Marguerite and her work outside of the academy. In 2001 an “installation opera” about Marguerite based on a libretto by the noted poet Anne Carson was performed in New York City; the following year a “Requiem für Marguerite Porete” with “dance and musical interpretation” was performed in Karlsruhe. A Web site promoting Eastern wisdom explains that Marguerite's “works illumine the nature of the soul in language which is remarkably reminiscent of Vedic teaching on the Atma, the individual soul.” And yes, she has been unofficially canonized, for another Web site informs readers about the “martyrdom” of “Saint Marguerite of Hainaut called la Porète.”.
