This article explores the consequences of falling costs of solar and wind power for the ethics of climate change mitigation. We suggest that price competitiveness of renewables reveals a divergence of interest between fossil fuel consumers and producers: cheap renewables strengthen precautionary arguments for aggressive mitigation for consumers but threaten the economic base of producers. As existing applications of the precautionary principle to climate change do not address this issue, we develop a novel approach based on lexical utilities. Given the (...) premise that climate catastrophe entails economic catastrophe but not vice versa, we argue that both producers and consumers should favor mitigation. (shrink)

1. Animal Cruelty Industrial farming is appallingly abusive to animals. Pigs. In America, nine-tenths of pregnant sows live in “gestation crates. ” These pens are so small that the animals can barely move. When the sows are first crated, they may flail around, in an attempt to get out. But soon they give up. Crated pigs often show signs of depression: they engage meaningless, repetitive behavior, like chewing the air or biting the bars of the stall. The sows live like (...) this for four months. Gestation crates will be phased out in Europe by the end of 2012, but they will still be used in America.1 In nature, pigs nurse their young for about thirteen weeks. But in industrial farms, piglets are taken from their mothers after about ten days. Because the piglets are weaned prematurely, they develop a lifelong craving to suck and chew. But the farmers don’t want them sucking and chewing on other pigs’ tails. So the growers routinely snip off the tails of all their pigs. They do this with a pair of pliers and no anesthetic. However, the whole tail is not removed; a tender stump remains. The point is to render the area sensitive, so the pigs being chewed on will fight back. Which they do.2 Over 113 million pigs are slaughtered each year in America.3 Typically, these pigs are castrated, their needle teeth are clipped, and one of their ears is notched for identification —all without pain relief.4 In nature, pigs spend up to three quarters of their waking hours foraging and exploring their environment.5 But in the factory farms, “tens of thousands of hogs spend their entire lives ignorant of earth or straw or sunshine, crowded together beneath a metal roof standing on metal slats suspended over a septic tank. ”6 Bored, and in constant pain, the pigs must perpetually inhale the fumes of their own waste. These pigs often get sick, and their ill health is exacerbated by the overcrowding. In 2000, the U.S. Department of Agriculture compared hog farms containing over 10,000 pigs—which is the norm—with farms containing under 2,000 pigs. (shrink)

Climate Change and the Moral Agent examines the moral foundations of climate change and makes a case for collective action on climate change by appealing to moralized collective self-interest, collective ability to aid, and an expanded understanding of collective responsibility for harm.

Moral philosophy is the study of what morality is and what it requires of us. As Socrates said, it's about "how we ought to live"-and why. It would be helpful if we could begin with a simple, uncontroversial definition of what morality is. Unfortunately, we cannot. There are many rival theories, each expounding a different conception of what it means to live morally, and any definition that goes beyond Socrates's simple formula-tion is bound to offend at least one of them. (...) This should make us cautious, but it need not paralyze us. In this chapter, I will describe the "minimum conception" of morality. (shrink)

A joke is amusing if and only if it’s fitting to be amused by it; an act is regrettable if and only if it’s fitting to regret it. Many philosophers accept these biconditionals and hold that analogous ones obtain between a wide range of additional evaluative properties and the fittingness of corresponding responses. Call these the _fit–value biconditionals_. The biconditionals give us a systematic way of recognizing the role of fit in our ethical practices; they also serve as the bedrock (...) of various metaethical projects, such as fitting-attitude analysis of value and the ‘fittingness first’ approach. Yet despite the importance of the biconditionals, there is very little discussion of their proper interpretation. This paper argues that any plausible interpretation of the fit_–_value biconditionals must disarm several kinds of apparent counterexample. For instance, that an achievement is pride-worthy doesn’t imply it is fitting for me to take pride in it because the achievement might not be mine or that of anyone close to me; that a joke is amusing doesn’t imply it is fitting for me to be amused by it for six straight months; and that a person is loveable doesn’t imply it is fitting for me to love him romantically because that person might be my sibling. We consider possible responses to such counterexamples and develop what we consider the most promising interpretation of the biconditionals. The upshot is that certain widespread assumptions about fit and its relation to value and reasons should be reconsidered. (shrink)

Liberalism faces a tension between its commitment to minimal interference with individual liberty and the urgent need for strong collective action on global climate change. This paper attempts to resolve that tension. It does so on the one hand by defending an expanded model of collective moral responsibility, according to which a set of individuals can be responsible, qua ?putative group?, for harm resulting from the predictable aggregation of their individual acts. On the other, it defends a collectivized version of (...) the harm principle. The claim is that the collectivized principle pushes the burden of argument, against coercively enforced measures to curtail climate change and compensate its victims, onto the global elite collectively responsible for environmental harms. Some such potential arguments are briefly considered and rejected. (shrink)

What words we use, and what meanings they have, is important. We shouldn't use slurs; we should use 'rape' to include spousal rape (for centuries we didn’t); we should have a word which picks out the sexual harassment suffered by people in the workplace and elsewhere (for centuries we didn’t). Sometimes we need to change the word-meaning pairs in circulation, either by getting rid of the pair completely (slurs), changing the meaning (as we did with 'rape'), or adding brand new (...) word-meaning pairs (as with 'sexual harassment'). A problem, though, is how to do this. One might worry that any attempt to change language in this way will lead to widespread miscommunication and confusion. I argue that this is indeed so, but that's a feature, not a bug of attempting to change word-meaning pairs. The miscommunications and confusion such changes cause can lead us, via a process I call transformative communicative disruption, to reflect on our language and its use, and this can be further, rather than hinder, our goal of improving language.

On the traditional relationalist conception of singular thought, a thought has singular content when it is based on an ‘information relation’ to its object. Recent work rejects relationalism and suggests singular thoughts are distinguished from descriptive thoughts by their inferential role: only thoughts with singular content can be employed in ‘direct’ inferences, or inferences that ‘trade on identity’. Firstly this view is insufficiently clear, because it conflates two distinct ideas—one about a kind of inference, the other a kind of process (...) that grounds inferences—under the title, ‘trading on identity’. Secondly, this leaves us without a notion that can be used as an alternative to relationalism about singular thought. The first notion is no more applicable to singular than to descriptive thought. The second may help us better understand singular thought, but does so, not by replacing the view that singular thoughts are information-based, but by helping us understand the nature of information-based thought.

Scholars have critiqued mainstream economic approaches to environmental valuation for decades. These critiques have intensified with the increased prominence of environmental valuation in decision-making. This paper has three goals. First, we summarise prominent critiques of monetary valuation, drawing mostly on the work of Clive Spash, who worked extensively on cost–benefit analysis early in his career and then became one of monetary valuation's most thorough and ardent critics. Second, we, as a group of scholars who study relational values, describe how relational (...) values research engages with and addresses many of the critiques of monetary valuation. Third, we offer suggestions for relational values research that continues and deepens its ability to respond to critiques of monetary valuation and contributes to transformative change towards sustainability.

Increasingly, metaphors are the target of political critique: Jewish groups condemn Holocaust imagery; mental health organizations, the metaphorical exploitation of psychosis; and feminists, “rape metaphors.” I develop a novel model for making sense of such critiques of metaphor.

Despite the increased prevalence of bioethics research that seeks to use empirical data to answer normative research questions, there is no consensus as to what an appropriate methodology for this would be. This review aims to search the literature, present and critically discuss published Empirical Bioethics methodologies.

Faultless disagreement and faultless retraction have been taken to motivate relativism for predicates of personal taste, like ‘tasty’. Less attention has been devoted to the question of what aspect of their meaning underlies this relativist behavior. This paper illustrates these same phenomena with a new category of expressions: appearance predicates, like ‘tastes vegan’ and ‘looks blue’. Appearance predicates and predicates of personal taste both fall into the broader category of experiential predicates. Approaching predicates of personal taste from this angle suggests (...) that their relativist behavior is due to their experience-sensitivity, rather than their evaluative meaning. Furthermore, appearance predicates hold interest beyond what they can teach us about predicates of personal taste. Examination of a variety of uses of appearance predicates reveals that they give rise to relativist behavior for a variety of reasons—including some that apply also to other types of expressions, such as epistemic modals and comparative terms. This paper thus serves both to probe the source of relativist behavior in discourse about personal taste, as well as to map out this kind of behavior in the rich and under-explored discourse about appearances.

Epistemologists of testimony have focused almost exclusively on the epistemic dynamics of simple testimony. We do sometimes testify by ways of simple, single sentence assertions. But much of our testimony is narratively structured. I argue that narrative testimony gives rise to a form of epistemic dependence that is far richer and more far reaching than the epistemic dependence characteristic of simple testimony.

Hate speech and misinformation are rife. How to respond? Counterspeech proposals say: with more and better speech. This paper considers the treatment of counterspeech in Maxime Lepoutre’s Democratic Speech In Divided Times. Lepoutre provides a nuanced defence of counterspeech. Some counterspeech, he grants, is flawed. But, he says: counterspeech can be debugged. Once we understand why counterspeech fails – when fail it does – we can engineer more effective counterspeech strategies. Lepoutre argues that the failures of counterspeech can be theorised (...) using the ideology of salience. Negative counterspeech fails because it reinforces the salience of the very ideas or associations that it contests. His solution? Positive counterspeech – a form of counterspeech which avoids the salience trap. I argue that the salience paradigm is ill-suited to theorise the failures of counterspeech. I suggest some alternatives. Further, I show that these alternative paradigms make importantly different practical recommendations – recommendations concerning how we ought to engineer our counterspeech – from those issued by the salience paradigm.

Simple claims with the verb ‘seem’, as well as the specific sensory verbs, ‘look’, ‘sound’, etc., require the speaker to have some relevant kind of perceptual acquaintance (Pearson, 2013; Ninan, 2014). But different forms of these reports differ in their perceptual requirements. For example, the copy raising (CR) report, ‘Tom seems like he’s cooking’ requires the speaker to have seen Tom, while its expletive subject (ES) variant, ‘It seems like Tom is cooking’, does not (Rogers, 1972; Asudeh and Toivonen, 2012). (...) This contrast has led some theorists to hold that the matrix subject in CR constructions is uniformly interpreted as the perceptual source (p-source) (Asudeh and Toivonen, 2012; Rett and Hyams, 2014). Others, based on examples of CR reports that seem not to require perception of the referent of the matrix subject, have taken the p-source interpretation instead to be non-uniform across CR reports (Landau, 2011; Doran, 2015). We reconsider these theoretical approaches to copy raising in light of new experimental work probing the sensitivity of these requirements to the matrix verb, the embedded ‘like’-clause, and the context. While we find some motivation for a non-uniform p-source analysis, it comes from importantly different cases than those others have relied on. Furthermore, our findings cast doubt on the prevalent assumption that the perceptual requirements of CR reports are to be captured solely by the presence or absence of the p-source interpretation. We suggest that the data motivating a non-uniform p-source view are better captured by an alternative approach, which makes use of a more minimal evidential source role, in place of the perceptual source role. We close by considering the relationship between English copy raising and evidential constructions cross-linguistically. (shrink)

However far we are from either in practice, basic global and intergenerational justice, including climate change mitigation, are taken to be theoretically compatible. If population grows as predicted, this could cease to be the case. This paper asks whether that tragic legacy can now be averted without hard or even tragic choices on population policy. Current generations must navigate between: a high-stakes gamble on undeveloped technology; violating human rights; demanding unbearable sacrifices of the already badly off; institutional unfairness across adults; (...) institutional unfairness across children; failing to protect children’s basic interests; and threatening the autonomy of the family. We are not yet forced to choose between bequeathing a tragic choice and making one, by adopting basically unjust measures. However, even the remaining options present a morally hard choice. The fact we face it is yet another damning indictment on the combined actions and collective failures of the global elite. (shrink)

This paper offers three objections to Leslie’s recent and already influential theory of generics :375–403, 2007a, Philos Rev 117:1–47, 2008): her proposed metaphysical truth-conditions are subject to systematic counter-examples, the proposed disquotational semantics fails, and there is evidence that generics do not express cognitively primitive generalisations.

By examining first-person descriptions of thought insertion I show that thought insertion is a complex and heterogeneous phenomenon. People experiencing this phenomenon have huge difficulty explaining what it is like due to the bizarre nature of the experience. Through careful analysis of first-person descriptions I identify some of the characteristics of thought insertion. I then briefly examine some of the philosophical literature regarding agency, ownership and thought insertion and conclude that the standard account of the basic characteristics of thought insertion (...) is inadequate when we consider the phenomenon as it is experienced. First person descriptions suggest that thought insertion is characterised by a lack of personal ownership and not simply by a loss of agency or authorship. This is an important factor that should inform research and therapeutic intervention. We cannot hope to arrive at appropriate therapeutic intervention or identify underlying neuronal mechanisms for the experience if we cannot say what the experience actually is. I further suggest that more analysis of first-person description is required for an improved account of the phenomenology of thought insertion. (shrink)

This Element presents a philosophical exploration of the concept of the 'model organism' in contemporary biology. Thinking about model organisms enables us to examine how living organisms have been brought into the laboratory and used to gain a better understanding of biology, and to explore the research practices, commitments, and norms underlying this understanding. We contend that model organisms are key components of a distinctive way of doing research. We focus on what makes model organisms an important type of model, (...) and how the use of these models has shaped biological knowledge, including how model organisms represent, how they are used as tools for intervention, and how the representational commitments linked to their use as models affect the research practices associated with them.

The so-called ‘mental files theory’ in the philosophy of mind stems from an analogy comparing object-concepts to ‘files’, and the mind to a ‘filing system’. Though this analogy appears in philosophy of mind and language from the 1970s onward, it remains unclear to many how it should be interpreted. The central commitments of the mental files theory therefore also remain unclear. Based on influential uses of the file analogy within philosophy, I elaborate three central explanatory roles for mental files. Next, (...) I outline several common criticisms of the file picture, which have been a source of resistance to the view. Finally, I outline several interpretations of the theory, thus highlighting that the best interpretation of the file-theory's central analogy remains a live issue. (shrink)

Paradigmatically, natural kinds are the kinds of thing or stuff that are classified by the natural sciences. The periodic table provides perhaps the best example of the potential importance of natural kinds for science. In the philosophy of psychiatry, debates over whether mental disorders can be natural kinds emerge because kinds of mental disorder are manifestly different from chemical kinds in various ways. While chemical kinds are precise, psychiatric kinds are fuzzy. While chemical kinds are objective, the identification of psychiatric (...) kinds is value-laden. Psychiatric classification involves classifying people, and unlike chemical elements, those people can respond to being classified in various ways. This chapter goes through these differences, one-by-one, and argues that despite them, mental disorders may be natural kinds. (shrink)

Philosophers have long been interested in love and its general role in morality. This volume focuses on and explores the complex relation between love and justice as it appears within loving relationships, between lovers and their wider social context, and the broader political realm. Special attention is paid to the ensuing challenge of understanding and respecting the lovers’ personal autonomy in all three contexts. Accordingly, the essays in this volume are divided into three thematic sections. Section I aims at shedding (...) further light on conceptual and practical issues concerning the compatibility or incompatibility of love and justice within relationships of love. For example, are loving relations inherently unjust? Might love require justice? Or do love and justice belong to distinct moral domains? The essays in Section II consider the relation between the lovers on the one hand and their broader societal environment on the other. Specifically, how exactly are love and impartiality related? Are they compatible or not? Is it unjust to favor one’s beloved? Finally, Section III looks at the political dimensions of love and justice. How, for instance, do various accounts of love inform how we are to relate to our fellow citizens? If love is taken to play an important role in fostering or hindering the development of personal autonomy, what are the political implications that need to be addressed, and how? In addressing these questions, this book engenders a better understanding both of conceptual and practical issues regarding the relation between love, justice, and autonomy as well as their broader societal and political implications. It will be of interest to advanced students and scholars working on the philosophy of love from ethical, political, and psychological angles. (shrink)

This article argues that parents have a special, shared duty to organize for collective action on climate change mitigation and adaptation, but not for the reason one might assume. The apparently obvious reason is that climate change threatens life, health and community for the next generation, and parents have a special duty to their children to protect their basic human interests. This argument fails because many parents could protect their children from these central harms without taking more general action to (...) combat climate change, let alone to mitigate it. Instead, subtler reasons are advanced, drawing on children’s relational interests or on their interests as moral agents. It is argued that parents owe it to their children to combat climate change because of the indirect impact on current children of serious threats to their children and grandchildren, and of being required to live in a radically unjust world. It is further argued that parents may owe it directly to their more distant descendants to mitigate climate change because of the role current parents played in bringing them into the world.

We offer a novel account of metalinguistic comparatives, such as 'Al is more wise than clever'. On our view, metalinguistic comparatives express comparative commitments to conventions. Thus, 'Al is more wise than clever' expresses that the speaker has a stronger commitment to a convention on which Al is wise than to a convention on which she is clever. This view avoids problems facing previous approaches to metalinguistic comparatives. It also fits within a broader framework—independently motivated by metalinguistic negotiations and convention-shiftingexpressions— (...) that gives linguistic conventions a role in the semantics.

This paper explores in detail Gorgias' defense of rhetoric in Plato 's Gorgias, noting its connections to earlier and later texts such as Aristophanes' Clouds, Gorgias' Helen, Isocrates' Nicocles and Antidosis, and Aristotle's Rhetoric. The defense as Plato presents it is transparently inadequate; it reveals a deep inconsistency in Gorgias' conception of rhetoric and functions as a satirical precursor to his refutation by Socrates. Yet Gorgias' defense is appropriated, in a streamlined form, by later defenders of rhetoric such as Isocrates (...) and Aristotle. They present it as an effective reductio against a critique of rhetoric that depends on the "harm criterion." This is puzzling, since Plato 's own critique of rhetoric does not depend on the harm criterion. On the other hand, Plato does seem to embrace the harm criterion as a more general principle—as if pre-emptively embracing the reductio —in his arguments about the good in the Meno and Euthydemus. Nonetheless, Isocrates and Aristotle seem to be deliberately misreading Plato on rhetoric: where he intends to criticize its intrinsic nature, they respond as if he were merely complaining about its contingent effects.

This paper examines what it is for a condition to be a disease. It falls into two sections. In the first I examine the best existing account of disease (as proposed by Christopher Boorse) and argue that it must be rejected. In the second I outline a more acceptable account of disease. According to this account, by disease we mean a condition that it is a bad thing to have, that is such that we consider the afflicted person to have (...) been unlucky, and that can potentially be medically treated. All three criteria must be fulfilled for a condition to be a disease. The criterion that for a condition to be a disease it must be a bad thing is required to distinguish the biologically different from the diseased. The claim that the sufferer must be unlucky is needed to distinguish diseases from conditions that are unpleasant but normal, for example teething. Finally, the claim that for a condition to be a disease it must be potentially medically treatable is needed to distinguish diseases from other types of misfortune, for example economic problems and legal problems.

Rachel Cohon offers an original interpretation of the moral philosophy of David Hume, focusing on two areas.

Classifying Madness (Springer, 2005) concerns philosophical problems with the Diagnostic and Statistical Manual of Mental Disorders, more commonly known as the D.S.M. The D.S.M. is published by the American Psychiatric Association and aims to list and describe all mental disorders. The first half of Classifying Madness asks whether the project of constructing a classification of mental disorders that reflects natural distinctions makes sense. Chapters examine the nature of mental illness, and also consider whether mental disorders fall into natural kinds. The (...) second half of the book addresses epistemic worries. Even supposing a natural classification system to be possible in principle, there may be reasons to be suspicious of the categories included in the D.S.M. I examine the extent to which the D.S.M. depends on psychiatric theory, and look at how it has been shaped by social and financial factors. I aim to be critical of the D.S.M. without being antagonistic towards it. Ultimately, however, I am forced to conclude that although the D.S.M. is of immense practical importance, it is unlikely to come to reflect the natural structure of mental disorders. (shrink)

Martha Nussbaum has expanded the capabilities approach to defend positive duties of justice to individuals who fall below Rawls’ standard for fully cooperating members of society, including sentient nonhuman animals. Building on this, David Schlosberg has defended the extension of capabilities justice not only to individual animals but also to entire species and ecosystems. This is an attractive vision: a happy marriage of social, environmental and ecological justice, which also respects the claims of individual animals. This paper asks whether it (...) is one that the capabilities approach can really deliver. Serious obstacles are highlighted. The potential for conflict between the capability-based entitlements of humans and those of nonhuman animals or ‘nature’ is noted, but it is argued that this does not constitute a decisive objection to the expanded capabilities approach. However, intra-nature conflicts are so widespread as to do so: the situation is outside the circumstances of justice as they are standardly understood. Schlosberg attempts to reconcile such conflicts by re-examining what it means to flourish as a sentient nonhuman animal. This fails, because of the distinction between flourishing as a species, which often requires predation, and flourishing as an individual, which is as frequently incompatible with it. Finally, the paper considers how a capabilities theorist might move beyond such conflicts, identifying two possible strategies (which are not themselves unproblematic) for reconciling the demands of humans, animals and ecosystems.

This paper aims to identify the key characteristics of model organisms that make them a specific type of model within the contemporary life sciences: in particular, we argue that the term “model organism” does not apply to all organisms used for the purposes of experimental research. We explore the differences between experimental and model organisms in terms of their material and epistemic features, and argue that it is essential to distinguish between their representational scope and representational target. We also examine (...) the characteristics of the communities who use these two types of models, including their research goals, disciplinary affiliations, and preferred practices to show how these have contributed to the conceptualization of a model organism. We conclude that model organisms are a specific subgroup of organisms that have been standardized to fit an integrative and comparative mode of research, and that it must be clearly distinguished from the broader class of experimental organisms. In addition, we argue that model organisms are the key components of a unique and distinctively biological way of doing research using models.Keywords: Experimental organism; Genetics; Model organism; Modeling; Philosophy of biology; Representation.

In this volume, Rachel Giora explores how the salient meanings of words - the meanings that stand out as most prominent and accessible in our minds - shape how we think and how we speak. For Giora, salient meanings display interesting effects in both figurative and literal language. In both domains, speakers and writers creatively exploit the possibilities inherent in the fact that, while words have multiple meanings, some meanings are more accessible than others. Of the various meanings weencode (...) in our mental lexicon for a given word or expression, we ascribe greater cognitive priority to some over others. Interestingly, the most salient meaning is not always the literal meaning. Giora argues that it is cognitively prominent salient meanings, rather than literal meanings, that play the most important role in the comprehension and production of language. She shows that even though context begins to affect comprehension immediately, it does so without obstructing the early accessing of salient meanings. Thus, the meaning we first attend to is the salient word meaning, regardless of contextual bias. Knowledge of salient meanings turns out to play a major role, perhaps the most important role, in the process of using and understanding of language. Going beyond the familiar effects of literal meaning and context, the Graded Salience Hypothesis presents the most comprehensive explanation for how we use language for meaning. In this volume, Giora presents her new model for the first time in a book-length treatment, with original and illuminating perspectives that will be of interest to linguists, philosophers, psychologists, and all who want to know more about just how we understand what we mean.

Comparison between different animal species is omnipresent in the history of science and medicine but rarely subject to focussed historical analysis. The articles in the “Working Across Species” topical collection address this deficit by looking directly at the practical and epistemic work of cross-species comparison. Drawn from papers presented at a Wellcome-Trust-funded workshop in 2016, these papers investigate various ways that comparison has been made persuasive and successful, in multiple locations, by diverse disciplines, over the course of two centuries. They (...) explore the many different animal features that have been considered to be comparable, and the ways that animals have shaped science and medicine through the use of comparison. Authors demonstrate that comparison between species often transcended the range of practices typically employed with experimental animal models, where standardised practises and apparatus were applied to standardised bodies to produce generalizable, objective data; instead, comparison across species has often engaged diverse groups of non-standard species, made use of subjective inferences about phenomena that cannot be directly observed, and inspired analogies that linked physiological and behavioural characteristics with the apparent affective state of non-human animals. Moreover, such comparative practices have also provided unusually fruitful opportunities for collaborative connections between different research traditions and disciplines. (shrink)
