Résumé: Les analogies peuvent être des outils précieux d’argumentation lors-qu’elles sont bonnes, mais quand elles sont mauvaises, elles faussent inévitablement la question qu’elles sont censées élucider. Tel est le cas de la comparaison entre la sécession et le divorce, qu’il s’agisse du divorce sous conditions ou du divorce sans égard à la faute. L’objectif de cet article est de montrer que la sécession se distingue empirique ment d’un divorce par trois différences significatives: entre personnes et peuple, entre mariage et union (...) politique, et entre divorce et sécession. Cela révèle que les deux versions de l’analogie du divorce sont inadéquates. Même si, cependant, ces écarts pou vaient être comblés et que l’analogie du divorce sous condition puisse être sauvée, je conteste le caractère approprié de l’autre version en montrant qu’aborder la sécession comme un divorce civil entraînerait des implications normatives contre-intuitives qui enlèveraient tout attrait à l’analogie du divorce sans égard à la faute, ou qui amèneraient ceux qui l’emploient à promouvoir des modifications irréalistes aux institutions légales internationales.

In the philosophy of perception, olfaction is the perennial problem child, presenting a range of difficulties to those seeking to define its proper referents, and its phenomenological content. Here, we argue that many of these difficulties can be resolved by recognizing the object-like representation of odors in the brain, and by postulating that the basic objects of olfaction are best defined by their biological value to the organism, rather than physico-chemical dimensions of stimuli. Building on this organism-centered account, we speculate (...) that the phenomenological space of olfaction is organized into a number of coarse affective dimensions that apply categorically. This organization may be especially useful for coupling sensation to decision-making and instrumental action in a sensory modality where the stimulus space is especially complex and high-dimensional.

© 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 talking about the compatibility of quantum observables, discussions often center on the question of whether the corresponding operators commute—even though commutativity is a coarse-grained notion that largely fails to capture the salient “nonclassical” features of quantum theory. Often, too, such discussions involve the issue of whether the operators in question satisfy a Heisenberg-like inequality, of the form ΔA·ΔB≥r>0—even though such inequalities are specific to unbounded operators and (for this and other reasons) are typically not a useful way to discuss (...) joint uncertainty in quantum mechanics. In the present paper we emphasize a simpler dichotomy, in which operator pairs (A, B) are classified according to whether or not states can be found with arbitrarily small dispersions in both A and B. If A and B cannot be made arbitrarily dispersionless simultaneously, then we call A and B an uncertainty pair. Otherwise, we call A and B a certainty pair. An interesting feature of uncertainty pairs in particular is that they are stable, in the sense that if A and B form an uncertainty pair, then slight enough perturbations of A and B must also form an uncertainty pair. This stability, obvious in the finite-dimensional case, follows in general from an operator inequality derived herein. A consequence of this inequality is that perturbed position and momentum operators X+δX and P+δP cannot share an eigenvector unless |δX|·|δP|≥ℏ/2. (Here vertical bars denote the operator norm.) This, despite the fact that (as we show) arbitrarily slight perturbations of X and P can fail to satisfy a Heisenberg inequality—a fact which raises interesting measurement issues in its own right.

In ‘The Ockhamization of the event sources of sound’ (2013), Roberto Casati, Elvira Di Bona, and Jérôme Dokic argue that ‘ockhamizing’ Casey O’Callaghan’s account of sounds as proper parts of their event sources yields their preferred view: that sounds are identical with their event sources. This article argues that the considerations Casati et al. marshal in favor of their view are actually stronger considerations in favor of a quite different view: a variant on the Lockean conception of sounds as ‘sensible (...) qualities’ that treats sounds as audible properties of their event sources.

Winning essay of the American Society for Aesthetics' inaugural Peter Kivy Prize. Extends Kivy's notion of sonic picturing through engagement with recent work in philosophy of perception. Argues that sonic pictures are more widespread and more aesthetically and artistically important than even Kivy envisioned. Topics discussed include: the nature of sonic pictures; the nature of sounds; what we can (and more importantly, cannot) conclude from musical listening; sonic pictures in film; beatboxing as an art of sonic picturing; and cover songs (...) as sonic pictures. To be published in the Journal of Aesthetics and Art Criticism. (shrink)

Times of prolonged conflict spur great minds to seek a lasting peace. Thus was the case of Warring States China, which saw the rise of the Hundred Schools of Thought, including the Doadejing and the Han Feizi, and Renaissance Italy, which produced Niccolò Machiavelli. Witnessing their respective societies fall prey to internal corruption and external aggression, all three thinkers sought ways to produce a strong, stable state that would allow both the leader and the populace to endure. Fortune and the (...) Dao: A Comparative Study of Machiavelli, the Daodejing, and the Han Feizi demonstrates where the shortcomings of each theory lie, with emphasis on the similarities among Machiavelli, Laozi, and Han Feizi. Jason P. Blahuta ultimately argues that if Machiavelli’s philosophy, the most comprehensive of the three theories, were supplemented by aspects of the Daodejing, the revision would potentially overcome the deficiencies of the original.

ABSTRACT This module is designed to sensitise you to the special needs of participants who belong to populations that are more vulner.

An increasingly unbridgeable gap exists between the supply and demand of transplantable organs. Human embryonic stem cell technology could solve the organ shortage problem by restoring diseased or damaged tissue across a range of common conditions. However, such technology faces several largely ignored immunological challenges in delivering cell lines to large populations. We address some of these challenges and argue in favor of encouraging contribution or intentional creation of embryos from which widely immunocompatible stem cell lines could be derived. Further, (...) we argue that current immunological constraints in tissue transplantation demand the creation of a global stem cell bank, which may hold particular promise for minority populations and other sub-groups currently marginalized from organ procurement and allocation systems. Finally, we conclude by offering a number of practical and ethically oriented recommendations for constructing a human embryonic stem cell bank that we hope will help solve the ongoing organ shortage problem.

Provocative, brutally honest, and timeless, Machiavelli’s _The Prince_ is one of the most important yet misunderstood writings in history. In it, Machiavelli lays bare the reality behind politics as it has always been practiced, teaching leaders to avoid the errors and failings of others while also educating those outside of government about what goes on inside the halls of power. This edition offers a new and lively translation of _The Prince_, written in fluid modern English that is impressively accurate to (...) the original source. It also includes extensive selections from the _Discourses on Livy_, together with a range of Machiavelli’s other works such as his poetry, his personal correspondence, and the _Florentine Histories_. The supplemental readings, engaging original introduction, and thorough annotations provided in this edition show the relevance of _The Prince_ to a wide range of themes: human nature, the philosophy of history, and the existential question all rulers face—how to survive in a world that is largely outside of one’s control.

Abstract. Found in the Primeval History in Genesis, the biblical concepts of the “image of God” and the “knowledge of good and evil” remain integral to Christian anthropology, especially with regard to the theologoumena of “fall” and “original sin.” All of these symbols are remained important and appropriate descriptors of the human condition, provided that contemporary academic theological anthropology engages in constructive dialogue with the natural and social sciences. Using Paul Ricoeur's notion of “second naïveté experience,” I illustrate the hermeneutical (...) significance of contemporary bio-cultural or socio-biological evolutionary theory for reformulating these concepts of Christian anthropology today.

Why do species fail to adapt? This has been a long-standing question since Darwin posed it, and is still often asked. How should we evaluate the adaptive success of an organism, and what is the relevant timescale to evaluate adaptation? Over a generation? Across the time span of a species? Here, I frame a perspective on the adaptive process and discuss how adaptation occurs and what factors affect adaptive potential. To provide a broad context for adaptation, I describe generalized species (...) cycles that address how species originate, change over time, and give rise to new species, and I reason that there is an adaptive continuum with three main limits to adaptation: time, chance, and speciation. As a final goal, I identify a set of research problems that this view of adaptation brings to the fore in order to better understand adaptation and its limits. (shrink)

In the United States of America, and in much of the world, corporations are afforded a great deal of rights to both protect themselves and others against legal action and mistreatment. To gain these rights, they defended themselves or were defended many times throughout the years in courts under the framework of “legal personhood”—but this same legal personhood is not afforded to most actual living creatures. There is enough similarity in the legal framework afforded to corporations that should be afforded (...) to animals as well, and more than enough evidence to show that it is increasingly necessary to protect and expand animal rights in this way. The argument is simple: because of their sentience, cognition, and emotional intelligence, animals deserve legal personhood. If we can make the argument that a corporation, which is incapable of these things listed above, should have certain unalienable rights, then it is illogical for us to make the argument that animals should not.

It has been argued by philosophers and cultural historians that the notion of wilderness as it has been developed in the West problematically separates—conceptually and practically—humans from wild nature. The human/wilderness dichotomy, it is said, potentially leads even well-intentioned, environmentally minded people to work for wilderness preservation at the expense of paying attention to our local, lived environment. Although Henry David Thoreau and John Muir are often taken to be key architects of the inherited notion of wilderness, I draw from (...) their differing descriptions of spending time in wild areas in orderto argue that Thoreau provides a view of the human-nature relationship that is not susceptible to this particular worry. Thoreau, much more than Muir, provides us with reasons to not ignore our local lived space in favor of protecting only more wild (i.e., less humanized) places. The contrast between the two does not diminish the value of Muir’s work, but it does remind us that key figures—Thoreau in this case—in the development of the dominant wilderness paradigm should not be set aside as unhelpful in our own efforts to better understand our relationship with local place.

While the social and ecological landscape of the twenty-first century is worlds away from the historical-cultural context in which the biblical myth-symbols of the image of God and the knowledge of good and evil first emerged, Philip Hefner's understanding that Homo sapiens image God as created co-creators presents a plausible starting point for constructing a second naïveté interpretation of biblical anthropology and a fruitful concept for envisioning and enacting our human future.

Abstract:This paper addresses the current debate in environmental ethics regarding the notion of wilderness. It has been argued by J. Baird Callicott and Michael Nelson, William Cronon, and others that our current idea of wilderness is deeply flawed, especially insofar as it draws a sharp dichotomy between us and the rest of nature. This paper first explores what it means (and what it does not) to say that “wilderness” is a constructed concept. It then describes some of the key objections (...) and solutions proposed in order to argue that the best approach to understanding the concept and place of wilderness is to embrace a pluralistic approach. This proposal would allow for mutually inconsistent and incommensurable ideas to co-exist without succumbing to the pitfalls of an anything-goes relativism. (shrink)

This study examined the performance and future predictions for the Middle East produced by 18 global climate models participating in the Intergovernmental Panel on Climate Change Fourth Assessment Report. Under the Special Report on Emission Scenarios A2 emissions scenario the models predict an overall temperature increase of ~1.4 K by mid-century, increasing to almost 4 K by late-century for the Middle East. In terms of precipitation the southernmost portion of the domain experiences a small increase in precipitation due to the (...) Northward movement of the Inter-Tropical Convergence Zone. The largest change however is a decrease in precipitation that occurs in an area covering the Eastern Mediterranean, Turkey, Syria, Northern Iraq, Northeastern Iran and the Caucasus caused by a decrease in storm track activity over the Eastern Mediterranean. Other changes likely to impact the region include a decrease of over 170,000 km 2 in viable rainfed agriculture land by late-century, increases in the length of the dry season that reduces the length of time that the rangelands can be grazed, and changes in the timing of the maximum precipitation in Northern Iran that will impact the growing season, forcing changes in cropping strategy or even crop types.

Social and political scientists, historians and others, have put forward a number of widely differing views concerning the ‘character’ of Islamic millenarian and/or Mahdist movements in Africa. The same is true of course with regard to the opinions ofscholars concerning the transformative capacity of Islam as an ideology. In this paper I want to look at one aspect only of Islamic millenarianism in the West African context, viz. its allegedly revolutionary character.

Imperatives cannot be true, but they can be obeyed or binding: `Surrender!' is obeyed if you surrender and is binding if you have a reason to surrender. A pure declarative argument — whose premisses and conclusion are declaratives — is valid exactly if, necessarily, its conclusion is true if the conjunction of its premisses is true; similarly, I suggest, a pure imperative argument — whose premisses and conclusion are imperatives — is obedience-valid (alternatively: bindingness-valid) exactly if, necessarily, its conclusion is (...) obeyed (alternatively: binding) if the conjunction of its premisses is. I argue that there are two kinds of bindingness, and that a vacillation between two corresponding variants of bindingness-validity largely explains conflicting intuitions concerning the validity of some pure imperative arguments. I prove that for each of those two variants of bindingness-validity there is an equivalent variant of obedience-validity. Finally, I address alternative accounts of pure imperative inference.

Mainstream environmental groups have long been criticized by more radical activists as being too willing to compromise with industry and development interests. Radical groups such as Earth First! and Earth Liberation Front were formed as a reaction explicitly against perceived failures of mainstream groups. Although the radical activism employed varied from direct action in the form of aggressive civil disobedience coupled with eco sabotage, the tactics of the radical groups suggest two strands of movement. For example, the actions and demands (...) of Earth First! seemingly fit their conviction that compromise is a betrayal of their moral convictions and results only in further deterioration of environmental protection, and the radical activism of this group can be seen to fit well within historically accepted norms of protest movements within constitutional democracies. In contrast, Earth Liberation Front does engage in what might be called ecoterrorism, a form of political violence. This article addresses the following emerging questions: Is an uncompromising approach an effective strategy for radical environmental activism in fostering positive environmental change? What is required of constructive democratic action? Can radical environmental activism be a resource for cooperative practices and coalition building? These questions relate to ecological justice, which is growing in importance as a paradigm that combines social concerns about the environment with issues of nature protection, thereby underlying the need for coordination of strategies and cooperation in order to bring about a positive change In this paper, we examine the positions and arguments of some radical environmental activists and their detractors, and analyse their moral beliefs and political attitudes. We claim that “No Compromise” is not an acceptable strategy for environmental activism. In the analysis that follows, we are not suggesting naively that only warm fellow-feelings, congeniality, and an overt willingness to compromise are reasonable responses to powerful contravening force. We argue instead that when used, strong - and even perhaps sometimes illegal - direct action can be conceptualized and carried out in a way that does not hinder all opportunities for effective compromise, coalition building, and the like, that are ultimately essential elements of most successful protest movements. We build on Martin Benjamin’s claim that compromise need not always involve moral capitulation or failure, but can be integrity-preserving. It can, we believe, be an effective means of moving a pro-environmental agenda forward. Key to our argument are the distinctions between moral and political compromise, and the interrelations between moral and political community. Seeing oneself as a part of a larger community in which decisions must be made, and recognizing responsibility towards the members of a moral community is essential to a full appreciation and effective use of compromise. These considerations are anchored in an approach that constructively links participatory democracy and radical activism. (shrink)
