© 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)

R. C. Sleigh's Leibniz and Arnauld: A Commentary on Their Correspondence is a very good book: it is detailed, clearly written, well argued and attentive to the historical background. The more I read it, the more I enjoyed it and the more I learned. Not only does it offer a wide variety of interesting points for the reader to agree and disagree with, it has, also, the virtue of pretty well forcing the reader to think about the issues involved and (...) their connection with a variety of other philosophical problems. It breaks a good deal of new ground and, as is the way with new ground-breaking, it sometimes only scratches the surface: it points out both the need for further, more detailed investigations and the way in which such investigations might fruitfully proceed. By and large, however, it does a great deal more than scratch the surface: its depth of discussion is such that only a comparably sized book could hope to discuss in all their ramifications the problems raised by Sleigh.

The Chicago school of pragmatism was one of the most controversial and prominent intellectual movements of the late 1800s and early 1900s. Spanning the ferment of academic and social thought that erupted in those turbulent times in America, the Chicago pragmatists earned widespread attention and respect for many decades. They were a central force in philosophy, contesting realism and idealism for supremacy in metaphysics, epistemology and value theory. Their functionalist views formed the Chicago school of religion, which sparked intense scrutiny (...) into the real meaning of theism, religious experience and the role of religious values in society. Their social standpoint on psychology generated the Chicago school of sociology, social psychology and symbolic interactionism that dominated the social sciences until the 1960s. Their educational philosophy was a major component of progressivism, aiming to make schools more responsive to the democratic and industrial character of the country. In economics, labour issues, civil rights and liberal politics, the Chicago school was also impossible to ignore This four-volume set focuses on the cornerstones of the thought grounding such intellectual activism: their philosophies of human nature, intelligence, values and social purpose. While other collections of the writings of the most prominent Chicago pragmatists (John Dewey, George Mead and James Tufts) offer some of their own individual work, no other collection captures the entire breadth and depth of the movement as a whole. Key writings of these major philosophers are set in their proper context of important writings of James Angell, Edward Ames, Addison Moore, and of many of their graduates who had significant careers, including Ella Flagg Young, H. Heath Bawden, Arthur Rogers, Irving King, Kate Gordon, Douglas Macintosh, William Wright, Clarence Ayres and Charles Morris. Also included are their debates with many critics, such as James Mark Baldwin, George Santayana, William Montague, Roy Wood Sellars and William Hocking. Spanning roughly fifty years, the 130 pieces are brought together from several dozens of now obscure and increasingly rare books, journals and archival sources. This collection will be indispensable for the study of American intellectual history, and especially the evolution of American philosophy, psychology, sociology, religion, education and politics. --130 articles gathered into an indispensable collection covering the entire Chicago pragmatism movement --all materials are reset, annotated, indexed and enhanced by new editorial introductions --includes a wealth of obscure, rare and hard-to-find original materials --indispensable for the study of American intellectual history, and especially the evolution of American philosophy, psychology, sociology, religion, education and politics.

While Autonomous Weapons Systems have obvious military advantages, there are prima facie moral objections to using them. By way of general reply to these objections, I point out similarities between the structure of law and morality on the one hand and of automata on the other. I argue that these, plus the fact that automata can be designed to lack the biases and other failings of humans, require us to automate the formulation, administration, and enforcement of law as much as (...) possible, including the elements of law and morality that are operated by combatants in war. I suggest that, ethically speaking, deploying a legally competent robot in some legally regulated realm is not much different from deploying a more or less well-armed, vulnerable, obedient, or morally discerning soldier or general into battle, a police officer onto patrol, or a lawyer or judge into a trial. All feature automaticity in the sense of deputation to an agent we do not then directly control. Such relations are well understood and well-regulated in morality and law; so there is not much challenging philosophically in having robots be some of these agents — excepting the implications of the limits of robot technology at a given time for responsible deputation. I then consider this proposal in light of the differences between two conceptions of law. These are distinguished by whether each conception sees law as unambiguous rules inherently uncontroversial in each application; and I consider the prospects for robotizing law on each. Likewise for the prospects of robotizing moral theorizing and moral decision-making. Finally I identify certain elements of law and morality, noted by the philosopher Immanuel Kant, which robots can participate in only upon being able to set ends and emotionally invest in their attainment. One conclusion is that while affectless autonomous devices might be fit to rule us, they would not be fit to vote with us. For voting is a process for summing felt preferences, and affectless devices would have none to weigh into the sum. Since they don't care which outcomes obtain, they don't get to vote on which ones to bring about. (shrink)

Reason and Value collects 15 new papers by leading contemporary philosophers on themes from the work of Joseph Raz. Raz has made major contributions in a wide range of areas, including jurisprudence, political philosophy, and the theory of practical reason; but all of his work displays a deep engagement with central themes in moral philosophy. The subtlety and power of Raz's reflections on ethical topics make his writings a fertile source for anyone working in this area. Especially significant are his (...) explorations of the connections between practical reason and the theory of value, which constitute a sustained and penetrating treatment of a set of issues at the very center of moral philosophy as it is practiced today. The contributors to the volume acknowledge the importance of Raz's contributions by engaging critically with his positions and offering independent perspectives on the topics that he has addressed. The volume aims both to honour Raz's accomplishments in the area of ethical theorizing, and to contribute to an enhanced appreciation of the significance of his work for the subject. (shrink)

The indexical thesis says that the indexical terms, “I”, “here” and “now” necessarily refer to the person, place and time of utterance, respectively, with the result that the sentence, “I am here now” cannot express a false proposition. Gerald Vision offers supposed counter-examples: he says, “I am here now”, while pointing to the wrong place on a map; or he says it in a note he puts in the kitchen for his wife so she’ll know he’s home even though he’s (...) gone upstairs for a nap, but then he leaves the house, forgetting to remove the note. The first sentence is false by virtue of “here” not necessarily referring to the place of utterance, the second sentence, by virtue of “now” not necessarily referring to the time of utterance. We argue that these sentences express falsehoods only because the terms are being used demonstratively, not indexically – the distinction pertains not to words simpliciter, but to uses of words. When used indexically, the terms refer in accord with the indexical thesis; but when used demonstratively, their referents depend on how devices of ostension are used with their utterance – pointings, and the like. Thus Vision’s first sentence really says, “I am there now”, referring to the place on the map the finger is pointing to. As for his second sentence, we distinguish the time of utterance or production of a sentence from the time of its uptake. Due to the pragmatics of interpretation, the sentence really says “I” – the person ‘uttering’ the note – “am here” – here where the note is, with the note serving as a kind of proxy ‘finger’ – “now” – where “now” refers to the time of uptake of the note, i.e., when it is read. “I” refers indexically, “here”, demonstratively, and “now”, indexically, but indexically to the time of uptake. Since the sentence is not purely indexical, its falsehood doesn’t threaten the indexical thesis. A similar treatment is given of teletyped messages about the typer’s location. (shrink)

The move towards the use of new technologies and the new focus on citizen engagement in Scotland provides the opportunity for e-democracy to emerge. Working towards the goal of e-democracy, the International Teledemocracy Centre is developing a body of ICT, supporting skills, tools and techniques, designed specifically to facilitate the use of technology, capable of enhancing democratic engagement. This paper begins to articulate how citizens are engaging with government and with their elected representatives about issues that concern them, using technology (...) specially designed for the purpose. The paper examines the nature of e-democracy and considers concepts of democracy, issues of democratization, and issues surrounding citizen access and participation. In addition, the paper discusses the design and use of two electronic tools developed by the ITC between 1999 and 2001 i. e. e-consultant and e-petitioner. Finally, the paper presents analyses of findings drawn from research to monitor and evaluate the use of these tools and the arrangements which accompany their entry into society. (shrink)

I argue that Gauthier's constrained-maximizer rationality is problematic. But standard Maximizing Rationality means one's preferences are only rational if it would not maximize on them to adopt new ones. In the Prisoner's Dilemma, it maximizes to adopt conditionally cooperative preferences. (These are detailed, with a view to avoiding problems of circularity of definition.) Morality then maximizes. I distinguish the roles played in rational choices and their bases by preferences, dispositions, moral and rational principles, the aim of rational action, and rational (...) decision rules. I argue that Maximizing Rationality necessarily structures conclusive reasons for action. Thus conations of any sort can base rational choices only if the conations are structured like a coherent preference function; rational actions maximize on such functions. Maximization-constraining dispositions cannot integrate into a coherent preference function. (shrink)

There are five main claims that may be made about life after death: We are reincarnated in the self-same body we had in life. We are reincarnated in another body. We are revived, or continue to live in a disembodied form.

Combining historical fact with a retelling of ancient myths and legends, Alistair Wilson shows how mathematics arose out of the problems of everyday life. He introduces concepts such as geometry, prime numbers, and trigonometry in a way that will totally disarm the reader who fears mathematics.

Descartes, Boyle and Hooke shared, with many other seventeenth-century figures, the view that mechanical explanations were the only intellectually satisfactory ones. They also all accepted the view that we have incorporeal souls. This generated a problem for them when they wrote about perception. In this area, indeed, Descartes seems to be almost a reluctant Cartesian. When we read his scientific writings, the incorporeal soul is not stressed, and Descartes happily speaks of physical, or of corporeal, ideas in discussing sensation, memory (...) and imagination.

How may nations protect their interests in space if its fragility makes military operations there self-defeating? This essay claims nations are in Prisoners Dilemmas on the matter, and applies David Gauthier’s theories about how it is rational to behave morally—cooperatively—in such dilemmas. Currently space-faring nations should i) enter into co-operative space sharing arrangements with other rational nations, ii) exclude—militarily, but with only terrestrial force—nations irrational or existentially opposed to other nations being in space, and iii) incentivize all nations into co-operation (...) by redistributing some space-generated wealth to nations that might otherwise ruin space. Further, since all nations are rationally incentivized to ever greater dependence on space, and since each, by threatening space, can hold hostage its benefits to all, each can demand resolution of terrestrial discontents with other nations. So each has a rational interest in treating others morally both in space and on terrestrial issues. (shrink)

David Gauthier claims that it can be rational to co-operate in a prisoner's dilemma if one has adopted a disposition constraining one's self from maximizing one's individual expected utility, i.e., a constrained maximizer disposition. But I claim cooperation cannot be both voluntary and constrained. In resolving this tension I ask what constrained maximizer dispositions might be. One possibility is that they are rationally acquired, irrevocable psychological mechanisms which determine but do not rationalize cooperation. Another possibility is that they are rationally (...) acquired preference-functions rationalizing cooperation as maximizing. I argue that if they are the first thing, then their adoption fails to make co-operation rational even if, as Gauthier also claims, actions are rational if they express rational dispositions. I then suggest that taking constrained maximizer dispositions to be things of the second sort would result in them being able to make co-operation rational, and that so-taking them therefore serves the bulk and spirit of Gauthier's larger claims, which I reconstruct accordingly.

To the normal reasons that we think can justify one in preferring something, x (namely, that x has objectively preferable properties, or has properties that one prefers things to have, or that x's obtaining would advance one's preferences), I argue that it can be a justifying reason to prefer x that one's very preferring of x would advance one's preferences. Here, one prefers x not because of the properties of x, but because of the properties of one's having the preference (...) for x. So-revising one's preferences is rational in paradoxical choice situations like Kavka's Deterrence Paradox. I then try to meet the following objections: that this is stoicist, incoherent, bad faith; that it conflates instrumental and intrinsic value, gives wrong solutions to the problems presented by paradoxical choice situations, entails vicious regresses of value justification, falsifies value realism, makes valuing x unresponsive to x's properties, causes value conflict, conflicts with other standards of rationality, violates decision theory, counsels immorality, makes moral paradox, treats value change as voluntary, conflates first- and second-order values, is psychologically unrealistic, and wrongly presumes that paradoxical choice situations can even occur.

This article focuses on the effectiveness of antihomophobia discourses and explores the process of teaching and learning about heteronormativity. The author offers an interrogation of the regulatory fictions within heteronormativity and frameworks of resistance and examines attempts to move beyond established views of sexual minority students and explore the ways in which queer research has, and continues to, bring a counternarrative to staid liberal notions of reform and the well-intentioned rhetoric of diversity and difference. This analysis raises critical questions about (...) the possibility of moving beyond standard antihomophobia curricula and questions approaches such as the one-off lecture format and other condensed discussions of heteronormativity and homophobia.

In Religious Studies xxvi Harold W. Noonan and Charles B. Daniels severally take issue with my ‘Reincarnation and Relativized Identity’. Both make valuable points but both, I think, have somewhat missed the point of my original article. In that paper I singled out five different views on the possibility of life after death: that we are reincarnated in the self-same body we had in our pre-mortem state; that we are reincarnated in another — in a different — body; that we (...) continue to exist in a disembodied form, which may or may not culminate in re-embodiment; that pre-mortem life is a dream from which postmortem life is the awakening; that none of the above holds: there is no life after death.

This paper reviews six attempts to give cooperative solutions to Prisoners Dilemmas: symmetry (agents are in identical situations, so should choose the same way, so should both choose cooperation because that’s better for each), mechanism (each agent should delegate the decision to a machine which will choose cooperation for them provided the other does likewise), inducement (the agents should make a side bet which pays off only upon both cooperating), resolution (each agent should resolve to cooperate, then act on the (...) resolution), alternative principle (rationality requires not dominance reasoning and so defecting, but constrained maximization or resolution compliance or “sophisticated” choosing, and so cooperation), and preference revision (each agent should acquire conditional preferences to cooperate, then cooperate provided the other agent has acquired similar preferences). It distinguishes one-stage from two-stage games, as well as endogenously available solutions (ones available to agents in the circumstances of the game merely due to the nature of rationality) from solutions requiring exogenous devices. It contrasts Edward McClennen’s endogenous solution, which is some combination of resolution and alternative principle solution, with David Gauthier’s endogenous alternative principle solution. It argues that all have problems, ones best solved by the endogenous preference revision solution defended by Duncan MacIntosh. (shrink)

G.E. Moore used to answer the question, 'What is philosophy?' by pointing to the books on his shelves & saying, 'Philosophy is what these books are about.' Philosophy of mind is what some of those books are about, & its enquiries frequently move into neighbouring areas, with logic, semantics, neurophysiology, literature, epistemology & metaphysics providing some obvious examples, as the papers in this collection reveal.

If one can get the targets of one's current wants only by acquiring new wants (as in the Prisoner's Dilemma), is it rational to do so? Arguably not. For this could justify adopting unsatisfiable wants, violating the rational duty to maximize one's utility. Further, why cause a want's target if one will not then want it? And people "are" their wants. So if these change, people will not survive to enjoy their wants' targets. I reply that one rationally need not (...) advance one's future wants, only current ones. Furthermore, rational choice seeks not utility (the co-obtaining of a want and its target), but satisfaction (the eventual obtaining of what is now wanted) -- otherwise, it would be irrational to care now about what happens after one dies. Finally, persons survive "rational" changes of values. Thus reflection on the rational revision of values illuminates the conditions on personal identity and the bases and aims of rational choice.
