© 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)

Aboutness has been studied from any number of angles. Brentano made it the defining feature of the mental. Phenomenologists try to pin down the aboutness-features of particular mental states. Materialists sometimes claim to have grounded aboutness in natural regularities. Attempts have even been made, in library science and information theory, to operationalize the notion. But it has played no real role in philosophical semantics. This is surprising; sentences have aboutness-properties if anything does. Aboutness is the first book to examine through (...) a philosophical lens the role of subject matter in meaning. A long-standing tradition sees meaning as truth-conditions, to be specified by listing the scenarios in which a sentence is true. Nothing is said about the principle of selection--about what in a scenario gets it onto the list. Subject matter is the missing link here. A sentence is true because of how matters stand where its subject matter is concerned. Stephen Yablo maintains that this is not just a feature of subject matter, but its essence. One indicates what a sentence is about by mapping out logical space according to its changing ways of being true or false. The notion of content that results--directed content--is brought to bear on a range of philosophical topics, including ontology, verisimilitude, knowledge, loose talk, assertive content, and philosophical methodology. Written by one of today's leading philosophers, Aboutness represents a major advance in semantics and the philosophy of language. (shrink)

[Stephen Yablo] The usual charge against Carnap's internal/external distinction is one of 'guilt by association with analytic/synthetic'. But it can be freed of this association, to become the distinction between statements made within make-believe games and those made outside them-or, rather, a special case of it with some claim to be called the metaphorical/literal distinction. Not even Quine considers figurative speech committal, so this turns the tables somewhat. To determine our ontological commitments, we have to ferret out all traces (...) of nonliterality in our assertions; if there is no sensible project of doing that, there is no sensible project of Quinean ontology. /// [Andre Gallois] I discuss Steve Yablo's defence of Carnap's distinction between internal and external questions. In the first section I set out what I take that distinction, as Carnap draws it, to be, and spell out a central motivation Carnap has for invoking it. In the second section I endorse, and augment, Yablo's response to Quine's arguments against Carnap. In the third section I say why Carnap's application of the distinction between internal and external questions runs into trouble. In the fourth section I spell out what I take to be Yablo's version of Carnap. In the last I say why that version is especially vulnerable to the objection raised in the second. (shrink)

Stephen Toulmin argues that the potential for reason to improve our lives has been hampered by a serious imbalance in our pursuit of knowledge. The centuries-old dominance of rationality has diminished the value of reasonableness. Toulmin issues a powerful call to redress the balance between rationality and reasonableness.

"Biophilia" is the term coined by Edward O. Wilson to describe what he believes is humanity's innate affinity for the natural world. In his landmark book Biophilia, he examined how our tendency to focus on life and lifelike processes might be a biologically based need, integral to our development as individuals and as a species. That idea has caught the imagination of diverse thinkers. The Biophilia Hypothesis brings together the views of some of the most creative scientists of our time, (...) each attempting to amplify and refine the concept of biophilia. The variety of perspectives -- psychological, biological, cultural, symbolic, and aesthetic -- frame the theoretical issues by presenting empirical evidence that supports or refutes the hypothesis. Numerous examples illustrate the idea that biophilia and its converse, biophobia, have a genetic component: fear, and even full-blown phobias of snakes and spiders are quick to develop with very little negative reinforcement, while more threatening modern artifacts -- knives, guns, automobiles -- rarely elicit such a response people find trees that are climbable and have a broad, umbrella-like canopy more attractive than trees without these characteristics people would rather look at water, green vegetation, or flowers than built structures of glass and concrete The biophilia hypothesis, if substantiated, provides a powerful argument for the conservation of biological diversity. More important, it implies serious consequences for our well-being as society becomes further estranged from the natural world. Relentless environmental destruction could have a significant impact on our quality of life, not just materially but psychologically and even spiritually. (shrink)

The principle of Anteriority says that prospects that are identical from the perspective of every possible person’s welfare are equally good overall. The principle enjoys prima facie plausibility, and has been employed for various theoretical purposes. Here it is shown using an analogue of the St Petersburg Paradox that Anteriority is inconsistent with central principles of axiology.

Countenancing unbounded utility in ethics gives rise to deep puzzles in formal decision theory. Here, these puzzles are taken as an invitation to assess the most fundamental principles relating probability and value, with the aim of demonstrating that unbounded utility in ethics is compatible with a desirable decision theory. The resulting theory frames further discussion of Expected Utility Theory and of principles concerning symmetries of utility.

Gayatri Chakravorty Spivaks seminal contribution to contemporary thought defies disciplinary boundaries. From her early translations of Derrida to her subsequent engagement with Marxism, feminism and postcolonial studies and her recent work on human rights, the war on terror and globalization, she has proved to be one of the most vital of present-day thinkers. In this book Stephen Morton offers a wide-ranging introduction to and critique of Spivaks work. He examines her engagements with philosophers and other thinkers from Kant to (...) Paul de Man, feminists from Cixous to Helie-Lucas and literary texts by Charlotte Bronte, J. M. Coetzee, Mahasweta Devi and Jean Rhys. Spivaks thought is also situated in relation to subaltern studies. Throughout the book, Morton interrogates the materialist basis of Spivaks thought and demonstrates the ethical and political commitment which lies at the heart of her work. Stephen Morton provides an ideal introduction to the work of this complex and increasingly important thinker. (shrink)

Orthodoxy holds that there is a determinate fact of the matter about every arithmetical claim. Little argument has been supplied in favour of orthodoxy, and work of Field, Warren and Waxman, and others suggests that the presumption in its favour is unjustified. This paper supports orthodoxy by establishing the determinacy of arithmetic in a well-motivated modal plural logic. Recasting this result in higher-order logic reveals that even the nominalist who thinks that there are only finitely many things should think that (...) there is some sense in which arithmetic is true and determinate.

This paper presents a new system of logic, LF, that is intended to be used as the foundation of the formalization of science. That is, deductive validity according to LF is to be used as the criterion for assessing what follows from the verdicts, hypotheses, or conjectures of any science. In work currently in progress, we argue for the unique suitability of LF for the formalization of logic, mathematics, syntax, and semantics. The present document specifies the language and rules of (...) LF, lays out some notational conventions, and states some basic technical facts about the system. (shrink)

In punishment, proportionality is the systematic mathematical relationship between the significance of the wrongdoing and the amount of punishment that may be imposed on the wrongdoer. In this chapter, Kershnar argues that there is no adequate equation for proportionality. The lack of an adequate equation rests on intuitions and the absence of a shared metric. If there is no equation for proportionality, then there is no proportionality. This is because if there is no equation for proportionality, then there is no (...) general justification for proportionality. Purported justifications of punishment that lack proportionality—specifically, consequentialism and consent theory—are implausible. The lack of proportionality, then, is a threat to the notion that some punishment is justified and, more generally, non-consequentialism. (shrink)

The notion of an extended simple region (henceforth ESR) has recently been marshalled in the service of arguments for a variety of conclusions. Exactly how to understand the idea of extendedness as it applies to simple regions, however, has been largely ignored, or, perhaps better, assumed. In this paper we first (§1) outline what we take to be the standard way that philosophers are thinking about extendedness, namely as an intrinsic property of regions. We then introduce an alternative picture (§2), (...) according to which extendedness is extrinsic. In §3 we argue that it matters which way of thinking about extendedness is the right one, since how ESRs behave is sensitive to what extendedness consists in, and various arguments that appeal to ESRs turn out to be unsound if extendedness is extrinsic rather than intrinsic.

Abstract: Does the evolving influence of humanity on the Earth’s environment call for new virtues? How might such virtues be seen as contributing to human flourishing? In this paper, I develop Aristotle’s discussion of magnificence and magnanimity to provide a framework within which to discuss such claims. I also defend the controversial view that even if genuinely new virtues may be involved, these may be virtues to which we should not aspire (now, or perhaps ever).

This chapter addresses the potential contributions of neuroscience to criminal justice decision-making and policy, with special emphasis on criminal responsibility. The central question is whether neuroscience is relevant to criminal justice. The general conclusion is that it is scarcely useful at present but may become more relevant as the science progresses. After explaining the meaning of criminal responsibility in use, the chapter speculates about the source of claims for the positive influence of neuroscience. The scientific status of behavioral neuroscience and (...) two radical challenges to responsibility neuroscience allegedly raises, determinism and the death of agency, are discussed next. Then, the specific relevance of neuroscience to criminal law and the use of neuroscience in criminal cases in the United States and abroad are addressed. The penultimate section points to some areas warranting modest optimism for the use of neuroscience in criminal justice. A brief conclusion follows. (shrink)

An examination of verbal hallucinations and thought insertion as examples of "alienated self-consciousness.".

Undergraduate students with no prior classroom instruction in mathematical logic will benefit from this evenhanded multipart text by one of the centuries greatest authorities on the subject. Part I offers an elementary but thorough overview of mathematical logic of first order. The treatment does not stop with a single method of formulating logic; students receive instruction in a variety of techniques, first learning model theory (truth tables), then Hilbert-type proof theory, and proof theory handled through derived rules. Part II supplements (...) the material covered in Part I and introduces some of the newer ideas and the more profound results of logical research in the twentieth century. Subsequent chapters introduce the study of formal number theory, with surveys of the famous incompleteness and undecidability results of Godel, Church, Turing, and others. The emphasis in the final chapter reverts to logic, with examinations of Godel's completeness theorem, Gentzen's theorem, Skolem's paradox and nonstandard models of arithmetic, and other theorems.

Transnational corporations have become actors with significant political power and authority which should entail responsibility and liability, specifically direct liability for complicity in human rights violations. Holding TNCs liable for human rights violations is complicated by the discontinuity between the fragmented legal/political structure of the TNC and its integrated strategic reality and the international state system which privileges sovereignty and non-intervention over the protection of individual rights. However, the post-Westphalian transition—the emergence of multiple authorities, increasing ambiguity of borders and jurisdiction (...) and blurring of the line between the public and private spheres—should facilitate imposing direct responsibility on transnational firms. Mechanisms for imposing direct responsibility on TNCs are considered including voluntary agreements and international law. However, I conclude that a hybrid public-private regime which relies on non-hierarchical compliance mechanisms is likely to be both more effective and consistent with the structure of the emerging transnational order.

Morgenbesser's Coin is a thought experiment that exemplifies a widespread disposition to infer counterfactual independence from causal independence. I argue that this disposition is mistaken by analysing a closely related thought experiment.

Recent work has brought to prominence the idea that some utterances contain occurrences of noun phrases that not only corefer, but do so in a particularly guaranteed or explicit way—call such occurrences ‘de jure coreferential’. Studies of de jure coreference have considered both the characteristics of the relation, and its explanation. Pinillos (154(2):301–324, 2011) argues that de jure coreference is non-transitive, and uses this as part of his argument for a new semantic primitive explaining de jure coreference. In this paper, (...) I draw attention to a neglected distinction between de jure coreference and another kind of coreference with which it might easily be confused. I then consider Pinillos’s claim that de jure coreference is non-transitive, and conclude that even using Pinillos’s definition of de jure coreference, it is far from straightforward that he has demonstrated the non-transitivity of de jure coreference. I question whether Pinillos’s characterisation of de jure coreference is adequate, and offer a plausible alternative characterisation. I show that on this new characterisation, there is no evidence that the relation is non-transitive. (shrink)

Hume thought that if you believed in powers, you believed in necessary connections in nature. He was then able to argue that there were none such because anything could follow anything else. But Hume wrong-footed his opponents. A power does not necessitate its manifestations: rather, it disposes towards them in a way that is less than necessary but more than purely contingent. -/- In this paper a dispositional theory of causation is offered. Causes dispose towards their effects and often produce (...) them. But a set of causes, even though they may succeed in producing an effect, cannot necessitate it since the effect could have been counteracted by some additional power. This would require a separation of our concepts of causal production and causal necessitation. The most conspicuous cases of causation are those where powers accumulate and pass a requisite threshold for an effect to occur. -/- We develop a model for representing powers as constituent vectors within an n-dimensional quality space, where composition of causes appears as vector addition. Even our resultant vector, however, has to be understood as having dispositional force only. This model throws new light on causal modality and cases of prevention, causation by absence and probabilistic causation. (shrink)

A COMPANION TO AESTHETICS This second edition of A Companion to Aesthetics examines questions that were among the earliest discussed by ancient philosophers, such as the nature of beauty and the relation between morality and art, while also addressing a host of new issues prompted by recent developments in the arts and in philosophy, including coverage of non-Western art traditions and of everyday and environmental aesthetics. The volume also canvases debates regarding the nature of representation, the relation between art and (...) truth, and the criteria for interpretation, which are among the most hotly discussed topics in contemporary philosophy. In this extensively revised and updated edition, 168 alphabetically arranged articles provide comprehensive treatment of the main topics and writers in aesthetics. Major additions include historical overviews from the prehistoric to the present and a section on the individual arts. A Companion to Aesthetics will serve students of philosophy, literary criticism, and cultural studies - as well as the educated general reader - both as a work of reference and, with its many substantial essays, as a guide to the best thinking about the arts from the ancient Greeks to the dawn of the twenty-first century.

In trying to enhance, improve or perfect ourselves through technological intervention, we can risk the very idea of a practical identity and self-possession. In thinking of the enhancement, improvement or perfection of the body through technological interventions, we ought to acknowledge limits in our outlook at least as seriously as we enjoy the considerable advances offered by technology in general. In postulating the chance of enhancement, improvement and perfection it is important to think about the distinction between what we can (...) and what we ought to do. In terms of scientific advance, this is not necessarily reflected clearly – it is often the case that scientific advance per se is taken to be ‘‘progress.’’ Progress in scientific research isn’t an easy notion in itself. Human progress, in being highly open to nuance and value, draws upon evaluation across a range of validity spheres. In tying a too-uncomplicated notion of scientific progress to the issue of human progress, there is a risk that we evaluate too narrowly our chances and our options. (shrink)

The Historical Dictionary of Existentialism explains the central claims of existentialist philosophy and the contexts in which it developed into one of the most influential intellectual trends of the 20th century. This is done through a chronology, an introductory essay, a bibliography, and more than 300 cross-referenced dictionary entries offering clear, accessible accounts of the life and thought of major existentialists like Jean-Paul Sartre, Martin Heidegger, Martin Buber, Karl Jaspers, Gabriel Marcel, Simone de Beauvoir, Albert Camus, and Maurice Merleau-Ponty, as (...) well as thinkers influential to its development such as Wilhelm Dilthey, Henri Bergson, Edmund Husserl, and Max Scheler. Historical Dictionary of Existentialism affords readers an integrated, critical, and historically-sensitive understanding of this important philosophical movement. (shrink)

What does it mean to think of philosophy in the condition of modernism, in which its relation to its past and future has become a relevant problem? This book argues that the writings of Wittgenstein, Heidegger, and Kierkegaard are best understood as responsive (each in their own way) to such questions. Through detailed analysis of these authors' most influential texts, Stephen Mulhall reorients our sense of the philosophical work each text aims to accomplish, engendering a critical dialogue between them (...) from which the elements of a new conception of philosophy might emerge.

A central theme throughout the impressive series of philosophical books and articles Stephen Toulmin has published since 1948 is the way in which assertions and opinions concerning all sorts of topics, brought up in everyday life or in academic research, can be rationally justified. Is there one universal system of norms, by which all sorts of arguments in all sorts of fields must be judged, or must each sort of argument be judged according to its own norms? In The (...) Uses of Argument Toulmin sets out his views on these questions for the first time. In spite of initial criticisms from logicians and fellow philosophers, The Uses of Argument has been an enduring source of inspiration and discussion to students of argumentation from all kinds of disciplinary background for more than forty years.
