Agriculture occupies 38% of the planet’s terrestrial surface, using 70% of freshwater resources. Its modern practice is dominated by an industrial–productivist discourse, which has contributed to the simplification and degradation of human and ecological systems. As such, agricultural transformation is essential for creating more sustainable food systems. This paper focuses on discursive change. A prominent discursive alternative to industrial–productivist agriculture is regenerative agriculture. Regenerative discourses are emergent, radically evolving and diverse. It is unclear whether they have the potential to generate (...) the changes required to shift industrial–productivist agriculture. This paper presents a literature-based discourse analysis to illustrate key thematic characteristics of regenerative agricultural discourses. The analysis finds that such discourses: situate agricultural work within nested, complex living systems; position farms as relational, characterised by co-evolution between humans and other landscape biota; perceive the innate potential of living systems as place-sourced; maintain a transformative openness to alternative thinking and practice; believe that multiple regenerative cultures are necessary for deeply regenerative agriculture; and depart from industrialism to varying degrees. The paper concludes by reviewing three transformative opportunities for regenerative discourses—discourse coalitions, translocal organising and collective learning. (shrink)

How can educators create space for students to practice making the worlds we are trying to collectively build? Inspired by genealogies that are grounded in and emerge from social movements, this paper uplifts the possibilities, tensions, and new questions that emerge when we take seriously the role of our classroom pedagogies. The authors offer a reflexive, methodological approach that pushes against the theory/practice divide and that stays with the importance of inhabiting theory through practice. They reflect on the role their (...) classroom pedagogies in enacting their commitments to justice, organizing their offerings around the following themes: (1) Enter, or how their learnings from previous teaching experiences shape praxis through the pauses, recalibrations, and persistent questions they provoke; (2) how they Open and create space in their classrooms through rituals and routines, and toward what ends; and finally, (3) how they aim to Build with their students within and beyond the bounds of the classroom. The authors share the guiding questions that prompted these reflections, as well as the echoes across their offerings, inviting readers to reflect on their own teaching practice in community.

Conceptual engineering is a philosophical method that aims to design and spread conceptual and linguistic devices to cause meaningful changes in the world. So far, however, conceptual engineers have struggled to successfully spread the conceptual and linguistic entities they have designed to their target communities. This paper argues that conceptual engineering is far more likely to succeed if it incorporates empirical data and empirical methods. Because the causal factors influencing successful propagation of linguistic or conceptual devices are as complicated and (...) interwoven as they are, proper empirical research will greatly boost the likelihood that propagation is successful. In arguing for the superiority of empirical conceptual engineering over armchair-based conceptual engineering, this paper proposes a framework for understanding the causal forces at play in propagation. This is a three-part framework between the label of a lexical item, the psychological states associated with the lexical item, and the worldly things associated with the lexical item. By understanding the way causal forces affecting propagation play out at these three levels, conceptual engineers can better conceptualize, study, and harness the different causal forces affecting the success of their conceptual engineering projects.

Conceptual engineering is the practice of revising concepts to improve how people talk and think. Its ability to improve talk and thought ultimately hinges on the successful dissemination of desired conceptual changes. Unfortunately, the field has been slow to develop methods to directly test what barriers stand in the way of propagation and what methods will most effectively propagate desired conceptual change. In order to test such questions, this paper introduces the masked time-lagged method. The masked time-lagged method tests people's (...) conceptual understanding at two different points in time without their knowledge of being tested, allowing us to measure conceptual revision in action. Using a masked time-lagged design on a content internalist framework, we attempted to revise PLANET and DINOSAUR in online participants to match experts' concepts. We successfully revised PLANET but not DINOSAUR, demonstrating some of the difficulties conceptual engineers face. Nonetheless, this paper provides conceptual engineers, regardless of framework, with the tools to tackle questions related to implementation empirically and head-on. (shrink)

When the Anglican Church Missionary Society started work on the East African coast in 1874 it had no intention of working among Muslims, nor did it mention Islam as a motivation for its desire to work with the people of the interior. This was due largely to the fact that members of the mission thought Islam in the region was stagnant and posed no threat to their work. As the organisation expanded inland, and as missionaries observed the Muslims of the (...) region, its attitudes and strategies towards Islam started to change. This article explores the reasons for these changes and discusses the early relations between missionaries and Muslims. (shrink)

During the latter part of the nineteenth century our description of nerve cell structure underwent a relatively unrecognized, though fundamental, transformation-a quiet revolution of sorts. The central problem facing scientists in neurology (the study of the nervous system) was a related pair: are nerve cells continuous with each other or not, and how is information conducted? Microscope resolution and staining techniques were inadequate at the time to yield definitive proof either way. I contend that explanatory coherence provides a means to (...) elucidate this instance of theory change in the history of science. The means of elucidation will be Thagard's computational model of explanatory coherence, ECHO (). (shrink)

Articulating and examining the likely consequences of different theoretical and policy approaches to economic justice serves to highlight potential trade-offs and conflicts among them, and helps us to think more carefully about these trade-offs and what their consequences might be. Some of us, for example, might support a liberal free trade regime because we believe it promotes greater income equalityamong countries. But we might also reasonably assert that such a regime exacerbates economic injusticeswithin some countriesby causing dislocation and unemployment, particularly (...) among vulnerable socioeconomic groups such as unskilled workers. This essay presents three models that seek to capture some of the central normative concerns that have been expressed by critics of economic globalization-communitarian, liberal internationalist, and cosmopolitan prioritarian. I indicate the kinds of economic models and data sets that are relevant to determining whether and to what extent greater openness to global trade poses a threat to economic justice as conceived by each of these approaches. Specifically, I use these analytical tools in order to relate changes in openness to foreign trade to other social and economic outcomes, particularly changes in income inequality and poverty, which have tended to draw the attention of nearly all theorists of economic justice. I characterize and critique the approach to economic justice that has been (implicitly) adopted by the major international institutions like the World Bank, International Monetary Fund, and World Trade Organization. I conclude with some policy implications and suggestions for further research in the area of international economic justice. (shrink)

A lively exploration of contemporary Buddhism from one of its most admired teachers. Do you feel at home right now? Or do you sense a hovering anxiety or uncertainty, an underlying unease that makes you feel just a bit uncomfortable, a bit distracted and disconnected from those around you? In The Road Home, Ethan Nichtern, a senior teacher in the Shambhala Buddhist tradition, investigates the journey each of us takes to find where we belong. Drawing from contemporary research on (...) meditation and mindfulness and his experience as a Buddhist teacher and practitioner, Nichtern describes in fresh and deeply resonant terms the basic existential experience that gives rise to spiritual seeking--and also to its potentially dangerous counterpart, spiritual materialism. He reveals how our individual quests for self-awareness ripple forward into relationships, communities, and society at large. And he explains exactly how, by turning our awareness to what's happening around us and inside us, we become able to enhance our sense of connection with others and, at the same time, change for the better our individual and collective patterns of greed, apathy, and inattention. In this wise and witty invitation to Buddhist meditation, Nichtern shows how, in order to create a truly compassionate and enlightened society, we must start with ourselves. And this means beginning by working with our own minds--in whatever state we find them in. (shrink)

Linguistic repetitions in children are conceptualized as negative in children with autism – echolalia, without communicative purpose – and positive in typically developing (TD) children – linguistic alignment involved in shared engagement, common ground and language acquisition. To investigate this apparent contradiction we analyzed spontaneous speech in 67 parent–child dyads from a longitudinal corpus (30 minutes of play activities at 6 visits over 2 years). We included 32 children with autism and 35 linguistically matched TD children (mean age at recruitment (...) 32.76 and 20.27 months). We found a small number of exact repetitions in both groups (roughly 1% of utterances across visits), which increased over time in children with autism and decreased in the TD group. Partial repetitions were much more frequent: children reused caregivers' words at high rates regardless of diagnostic group (24% of utterances at first visit), and this increased in frequency (but not level) over time, faster for TD children (at final visit: 33% for autism, 40% for TD). The same happened for partial repetition of syntax and semantic alignment. However, chance alignment (as measured by surrogate pairs) also increased and findings for developmental changes were reliable only for syntactic and semantic alignment. Children with richer linguistic abilities also displayed a higher tendency to partially re–use their caregivers' language (alignment rates and semantic alignment). This highlights that all children commonly re–used the words, syntax, and topics of their caregivers, albeit with some quantitative differences, and that most repetition was at least potentially productive, with repeated language being re–contextualized and integrated with non–repeated language. The salience of echolalia in ASD might be partially explained by slight differences in frequency, amplified by lower semantic alignment, persistence over time, and expectations of echolalia. More in–depth qualitative and quantitative analyses of how repetitions are used and received in context are needed. (shrink)

In the United States, approximately 2.53 million people sustain a concussion each year. Relative to adults, youth show greater cognitive deficits following concussion and a longer recovery. An accurate and reliable imaging method is needed to determine injury severity and symptom resolution. The primary objective of this study was to characterize concussions with diffusion tensor imaging. This was performed through a normative Z-scoring analysis of DTI metrics, fractional anisotropy, axial diffusivity, and radial diffusivity, to quantify patient-specific injuries and identify commonly (...) damaged brain regions in paediatric concussion patients relative to healthy controls. It was hypothesized that personalizing the detection analysis through normative Z-scoring would provide an understanding of trauma-induced microstructural damage. Concussion patients were volunteers recruited from the Emergency Department of the McMaster Children’s Hospital with a recent concussion, 9 males and 17 females, mean age 14.22 ± 2.64, while healthy paediatric brain DTI datasets were obtained from an MRI data repository. Significant abnormalities were commonly found in the longitudinal fasciculus, fronto-occipital fasciculus, and corticospinal tract, while unique abnormalities were localized in a number of other areas reflecting the individuality of each child’s injury. Total injury burden, determined by the number of regions containing outliers per DTI metric per patient, was used as the metric to quantify the overall injury severity of each patient. The primary outcome of this analysis found that younger patients experienced a significantly greater injury burden when measured using fractional anisotropy. These results show that DTI was able to detect microstructural changes caused by concussion, on a per-person basis, and has the potential to be a useful tool for improving diagnostic accuracy and prognosis of a concussion.

This paper investigates a special kind of social meaning-making manifest in how we experience static objects and properties of our everyday world. This happens, for example, when we recognize objects like vacuum cleaners, sliced tomatoes, and sneakers as placed in special sites in the environment. Given the compositional features of such images, we see them as designed to accomplish communicative functions. It is argued that object configurations of this kind are recognized as externalized ostensive cues. They are seen as having (...) been created with the intention of setting off an intersubjective mode of perception. This significantly changes the perceiver’s semiotic exploration of the scene. From a ‘private’ mode of sense-making mostly structured by reference to episodic, autobiographical experiential content, the perceiver takes a language stance. In other words, the perceiver adopts a qualitatively different meaning-constructing strategy in dealing with such images. Defending this claim, we present evidence from an empirical investigation of 20 participants’ construals of photographic images depicting everyday static objects. We show that a subset of these object configurations evoke a special kind of socially responsive attitude as manifested in participants’ introspective reports. The importance of these findings is brought out by discussion of parallels in neuro-cognitive work and how ostensive cues influence infant behavior. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethan’s GiftMichelle BurgessEthan was your average boy next door. He loved everything most 8–year–old boys do including playing baseball, swimming, and watching his favorite baseball team, the Philadelphia Phillies.On December 3rd 2008, life for our family changed forever when Ethan was diagnosed with Diffuse Intrinsic Pontine Glioma, a rare inoperable brainstem tumor. DIPG is in essence a death sentence. There are no survivors and life expectancy after (...) diagnosis is only 9–12 months. Our family was devastated.For the next 14 months, we lived life to the fullest, never taking a single moment or day for granted. As Ethan’s condition worsened, and it became clear that he was close to passing, I spoke with Ethan’s doctor about my desire to be able to donate Ethan’s corneas and his brain tumor for research. He informed me that because of Ethan’s type of tumor that he may be a candidate for donation of other organs as well if that is something we wanted to do.Knowing that there was nothing we could do to save Ethan, it was something that we felt we could do to help others so we decided to explore the option of donating Ethan’s other organs. We were put in contact with the Gift of Life.Two representatives from Gift of Life came to our home and discussed at length with us what would have to happen to make organ donation possible at the time of Ethan’s passing. Specifically that Ethan would have to pass away at the hospital and in the operating room. This was very different than the hospice environment that we had planned. They also had told us that Ethan was only the second young person that they had ever dealt with that the families had planned ahead of time to donate organs. The other person was a teenager who planned his own organ donation.On January 26th 2010, Ethan’s pain had become unmanageable at home and his breathing had become very labored. I spoke with his oncologist and he advised me to bring Ethan to the hospital to try and get his pain under control.We loaded Ethan up in the car for the one–hour car ride to the hospital. On the way to the hospital Ethan fell asleep while being cuddled by me in the backseat. When we arrived at the hospital we noticed that his fingers and toes had turned purple. The nurses immediately checked his oxygen and it had fallen to only 10 %.The doctors advised that he had slipped into a coma in the car, one that he would never awake from. He was immediately placed on life support. A scan was done and it was evident that the progressing tumor was placing pressure on the areas of the brain that controlled basic life functions such as breathing. Ethan could not recover.The decision was made to begin to look for recipients for Ethan’s organs. Because Ethan had not reached the point of brain death, his donation would have to be a post cardiac death transplant, meaning, life support would be removed, when his heart stopped beating and he passed away, the organ procurement would begin. However, he [End Page E1] would not be able to donate his heart. This was very sad for us, knowing how strong his little heart was, but we did understand the process.On January 28th 2010, our family spent the day saying goodbye to Ethan. Even though he could not respond, we know that he could hear us. The nurse was wonderful, doing everything possible to accommodate our large family and despite all the tubes and machines, make it so that I could cuddle with my little boy one last time.Ethan was moved to the operating room and with his stepfather and I on one side and his father and stepmother on the other, life support was removed. Watching my son take his last breath, while I held his hand, kissed his cheeks, told him I loved him and that it was okay to let go and go to Heaven was the hardest moment of... (shrink)

Despite its status at the heart of a closely related field, philosophers have so far mostly overlooked a phenomenon sociolinguists call ‘social meaning’. My aim in this paper will be to show that by properly acknowledging the significance of social meanings, we can identify an important new set of forms that discursive injustice takes. I begin by surveying some data from variationist sociolinguistics that reveal how subtle differences in the way a particular content is expressed allow us to perform importantly (...) different illocutionary actions, actions we use to do things like constructing a public persona and building a rapport with an audience. The social importance of these activities and the pervasiveness of our engagement in them means that the ethical stakes involved are high—substantial injustices may result if speakers from different social groups are differently empowered with regard to the illocutionary possibilities made available to them by variation.

Between 1945 and 1953, while the Soviet Union confronted postwar reconstruction and Cold War crises, its unchallenged leader Joseph Stalin carved out time to study scientific disputes and dictate academic solutions. He spearheaded a discussion of "scientific" Marxist-Leninist philosophy, edited reports on genetics and physiology, adjudicated controversies about modern physics, and wrote essays on linguistics and political economy. Historians have been tempted to dismiss all this as the megalomaniacal ravings of a dying dictator. But in Stalin and the Soviet Science (...) Wars, Ethan Pollock draws on thousands of previously unexplored archival documents to demonstrate that Stalin was in fact determined to show how scientific truth and Party doctrine reinforced one another. Socialism was supposed to be scientific, and science ideologically correct, and Stalin ostensibly embodied the perfect symbiosis between power and knowledge. Focusing on six major postwar debates in the Soviet scientific community, this elegantly written book shows that Stalin's forays into scholarship can be understood only within the context of international tensions, institutional conflicts, and the growing uncertainty about the proper relationship between scientific knowledge and Party-dictated truths. The nature of Stalin's interventions makes clear that more was at stake than high politics: these science wars were about asserting that the Party was rational and modern, and about codifying the Soviet worldview in a battle for the hearts and minds of people around the globe during the early Cold War. Ultimately, however, the effort to develop a scientific basis for Soviet ideology undermined the system's legitimacy. (shrink)

Standard semantic theories predict that non-deictic readings for complex demonstratives should be much more widely available than they in fact are. If such readings are the result of a lexical ambiguity, as Kaplan (1977) and others suggest, we should expect them to be available wherever a definite description can be used. The same prediction follows from ‘hidden argument’ theories like the ones described by King (2001) and Elbourne (2005). Wolter (2006), however, has shown that complex demonstratives admit non-deictic interpretations only (...) when a precise set of structural constrains are met. In this paper, I argue that Wolter’s results, properly understood, upend the philosophical status quo. They fatally undermine the ambiguity theory and demand a fundamental rethinking of the hidden argument approach. (shrink)

Much has been written on whether practical knowledge (knowledge-how) reduces to propositional knowledge (knowledge-that). Less attention has been paid to what we call deliberative knowledge (knowledge-to), i.e., knowledge ascriptions embedding other infinitival questions, like _where to meet_, _when to leave_, and _what to bring_. We offer an analysis of knowledge-to and argue on its basis that, regardless of whether knowledge-how reduces to knowledge-that, no such reduction of knowledge-to is forthcoming. Knowledge-to, unlike knowledge-that and knowledge-how, requires the agent to have formed (...) certain conditional intentions. We discuss the philosophical implications for knowledge-how, deliberative questions, and virtue. (shrink)

What determines the meaning of a context-sensitive expression in a context? It is standardly assumed that, for a given expression type, there will be a unitary answer to this question; most of the literature on the subject involves arguments designed to show that one particular metasemantic proposal is superior to a specific set of alternatives. The task of the present essay will be to explore whether this is a warranted assumption, or whether the quest for the one true metasemantics might (...) be a Quixotic one. We argue that there are good reasons—much better than are commonly appreciated—for thinking the latter, but that there nevertheless remains significant scope for metasemantic theorizing. We conclude by outlining our preferred option, metasemantic pluralism. (shrink)

Stojnić et al. (2013, 2017) argue that the reference of demonstratives is fixed without any contribution from the extra-linguistic context. On their `prominence/coherence' theory, the reference of a demonstrative expression depends only on its context-independent linguistic meaning. Here, we argue that Stojnić et al.’s striking claims can be maintained in only the thinnest technical sense. Instead of eliminating appeals to the extra-linguistic context, we show how the prominence/coherence theory merely suppresses them. Then we ask why one might be tempted to (...) try and offer such a view. Since we are rather sympathetic to the motivations we find, we close by sketching a more plausible alternative. (shrink)

I have two aims for the present paper, one narrow and one broad. The narrow aim is to show that a class of data originally described by Lynsey Wolter empirically undermine the leading treatments of complex demonstratives that have been described in the literature. The broader aim of the paper is to show that Wolter demonstratives, as I will call the constructions I focus on, are a threat not just to existing treatments, but to any possible theory that retains the (...) uncontroversial assumptions that relative clauses always form a constituent with the nouns they modify, and that semantic composition proceeds sequentially and locally, with the inputs to interpretation having the structure syntax tells us they do.

I present unexplored and unaccounted for uses of 'wants'. I call them advisory uses, on which information inaccessible to the desirer herself helps determine what she wants. I show that extant theories by Stalnaker, Heim, and Levinson fail to predict these uses. They also fail to predict true indicative conditionals with 'wants' in the consequent. These problems are related: intuitively valid reasoning with modus ponens on the basis of the conditionals in question results in unembedded advisory uses. I consider two (...) fixes, and end up endorsing a relativist semantics, according to which desire attributions express information-neutral propositions. On this view, 'wants' functions as a precisification of 'ought', which exhibits similar unembedded and compositional behavior. I conclude by sketching a pragmatic account of the purpose of desire attributions that explains why it made sense for them to evolve in this way. (shrink)

In the last two decades, there has been a blossoming literature aiming to counter the neglect of plant capacities. In their recent paper, Miguel Segundo-Ortin and Paco Calvo begin by providing an overview of the literature to then question the mistaken assumptions that led to plants being immediately rejected as candidates for sentience. However, it appears that many responses to their arguments are based on the implicit conviction that because animals have far more sophisticated cognition and agency than plants, and (...) that plants should not have the same moral status as animals, plants should not have any moral status. Put in simpler terms: it is not as bad to eat plants than to eat, say, pigs. While there are still uncertainties around comparative moral and policy implications between animals and plants, given a gradualist account of quasi-sentience and partial moral status, both of which we claim are a matter of degree, we may not have to abolish our convictions by declaring that plants have no sentience or moral status at all. Indeed, we can hold two things at the same time: that animals and plants have moral status, but animals have prima facie more moral status than plants. (shrink)

In this paper, I argue that the ‘social meanings’ associated with sociolinguistic variation put pressure on the standard philosophical conception of language, according to which the foremost thing we do with words is exchange information. Drawing on parallels with the explanatory challenge posed by slurs and pejoratives, I argue that the best way to understand social meanings is to think of them in speech act theoretic terms. I develop a distinctive form of pluralism about the performances realized by means of (...) sociolinguistic variants, and I claim that engagement with such performances is an utterly pervasive feature of our linguistic activity.

Recently, philosophers have offered compelling reasons to think that demonstratives are best represented as variables, sensitive not to the context of utterance, but to a variable assignment. Variablists typically explain familiar intuitions about demonstratives—intuitions that suggest that what is said by way of a demonstrative sentence varies systematically over contexts—by claiming that contexts initialize a particular assignment of values to variables. I argue that we do not need to link context and the assignment parameter in this way, and that we (...) would do better not to. (shrink)

Nelson et al.(2023) argue that the inclusion of personal experience in bioethical debates has significant benefits and liabilities, illustrating their claim with two examples: unproven medical treatments and disability bioethics. We believe that the benefits of including personal experience in disability bioethics far exceed its liabilities. The absence of participants with relevant experience impoverishes and biases bioethical debates, while the biases risked by their inclusion are hardly unique to personal experiences and are readily mitigated.

The aim of this book is to help students write mathematics better. Throughout it are large exercise sets well-integrated with the text and varying appropriately from easy to hard.

Vaccine refusal is not a free rider problem. The claim that vaccine refusers are free riders is inconsistent with the beliefs and motivations of most vaccine refusers. This claim also inaccurately depicts the relationship between an individual’s immunization choice, their ability to enjoy the benefits of community protection, and the costs and benefits that individuals experience from immunization and community protection. Modeling vaccine refusers as free riders also likely distorts the ethical analysis of vaccine refusal and may lead to unsuccessful (...) policy interventions. (shrink)

Modal logic has been used to analyze potential infinity and potentialism more generally. However, the standard analysis breaks down in cases of divergent possibilities, where there are two or more possibilities that can be individually realized but which are jointly incompatible. This paper has three aims. First, using the intuitionistic theory of choice sequences, we motivate the need for a modal analysis of divergent potentialism and explain the challenges this involves. Then, using Beth–Kripke semantics for intuitionistic logic, we overcome those (...) challenges. Finally, we apply our modal analysis of divergent potentialism to make choice sequences comprehensible in classical terms. (shrink)

Together with Plato's Republic, Jean-Jacques Rousseau's Social Contact is regarded as one of the most original examples of Utopian political engineering in the history of ideas. Similar to the Republic, Rousseau's Social Contract is better known today for its author's idiosyncratic view of political justice than its lessons on law-making or governance in any concrete sense. Challenging this common view, Rousseau, Law and the Sovereignty of the People examines the Genevan's contribution as a constitutionalist and builder of institutions, relating his (...) major ideas to issues and debates in twenty-first century political science.

The Knower paradox purports to place surprising a priori limitations on what we can know. According to orthodoxy, it shows that we need to abandon one of three plausible and widely-held ideas: that knowledge is factive, that we can know that knowledge is factive, and that we can use logical/mathematical reasoning to extend our knowledge via very weak single-premise closure principles. I argue that classical logic, not any of these epistemic principles, is the culprit. I develop a consistent theory validating (...) all these principles by combining Hartry Field's theory of truth with a modal enrichment developed for a different purpose by Michael Caie. The only casualty is classical logic: the theory avoids paradox by using a weaker-than-classical K3 logic. I then assess the philosophical merits of this approach. I argue that, unlike the traditional semantic paradoxes involving extensional notions like truth, its plausibility depends on the way in which sentences are referred to--whether in natural languages via direct sentential reference, or in mathematical theories via indirect sentential reference by Gödel coding. In particular, I argue that from the perspective of natural language, my non-classical treatment of knowledge as a predicate is plausible, while from the perspective of mathematical theories, its plausibility depends on unresolved questions about the limits of our idealized deductive capacities.

The twenty-first century will witness an unprecedented decline in the diversity of the world’s languages. While most philosophers will likely agree that this decline is lamentable, the question of what exactly is lost with a language has not been systematically explored in the philosophical literature. In this paper, I address this lacuna by arguing that language loss constitutes a problematic form of illocutionary silencing. When a language disappears, past and present speakers lose the ability to realize a range of speech (...) acts that can only be realized in that language. With that ability, speakers lose something in which they have a fundamental interest: their standing as fully empowered members of a linguistic community. (shrink)

The current work examines how cues traditionally used to signal environmental friendliness, specifically the color green and eco-labels, and influence product efficacy perceptions and subsequent purchase intentions. Across three experiments, we find that environmental cues used in isolation reduce perceptions of product efficacy. We argue that this efficacy discounting effect occurs because the isolated use of an environmental cue introduces category ambiguity by activating competing functionality and environmentally friendly schemas during evaluation. We discuss the implications of our findings for research (...) on environmental consumption as well as offer insight into the effective use of environmental cues on product packaging. (shrink)

Which function is computed by a Turing machine will depend on how the symbols it manipulates are interpreted. Further, by invoking bizarre systems of notation it is easy to define Turing machines that compute textbook examples of uncomputable functions, such as the solution to the decision problem for first-order logic. Thus, the distinction between computable and uncomputable functions depends on the system of notation used. This raises the question: which systems of notation are the relevant ones for determining whether a (...) function is computable? These are the acceptable notations. I argue for a use criterion of acceptability: the acceptable notations for a domain of objects D\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {D}}$$\end{document} are the notations that we can use for the usual D\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {D}}$$\end{document}-activities. Acceptable notations for natural numbers are ones that we can count with. Acceptable notations for logical formulas are the ones that we can use in inference and logical analysis. And so on. This criterion makes computability a relative notion—whether a function is computable depends on which notations are acceptable, which is relative to our interests and abilities. I argue that this is not a problem, however, since there is independent reason for taking the extension of computable function to be relative to contingent facts. Similarly, the fact that the use criterion makes a mathematical distinction depend on practical concerns is also not a problem because it dovetails with similar phenomena in other areas of computability theory, namely the roles of notation in computation over real numbers and of Extended Church’s Thesis in complexity theory.

It is increasingly common for philosophers to rely on the notion of an idealised listener when explaining how the semantic values of context-sensitive expressions are determined. Some have identified the semantic values of such expressions, as used on particular occasions, with whatever an appropriately idealised listener would take them to be. Others have argued that, for something to count as the semantic value, an appropriately idealised listener should be able to recover it. Our aim here is to explore the range (...) of ways that such idealisation might be worked out, and then to argue that none of these results in a very plausible theory. We conclude by reflecting on what this negative result reveals about the nature of meaning and responsibility. (shrink)

This book argues that the philosophical history of India contains a tradition of skepticism about philosophy represented most clearly by three figures: Nāgārjuna, Jayarāśi, and Śrī Harṣa. Furthermore, understanding this tradition ought to be an important part of our contemporary metaphilosophical reflections on the purposes and limits of philosophy.

Although much technical and philosophical attention has been given to relevance logics, the notion of relevance itself is generally left at an intuitive level. It is difficult to find in the literature an explicit account of relevance in formal reasoning. In this article I offer a formal explication of the notion of relevance in deductive logic and argue that this notion has an interesting place in the study of classical logic. The main idea is that a premise is relevant to (...) an argument when it contributes to the validity of that argument. I then argue that the sequents which best embody this ideal of relevance are the so-called perfect sequents—that is, sequents which are valid but have no proper subsequents that are valid. Church’s theorem entails that there is no recursively axiomatizable proof-system that proves all and only the perfect sequents, so the project that emerges from studying perfection in classical logic is not one of finding a perfect subsystem of classical logic, but is rather a comparative study of classifying subsystems of classical logic according to how well they approximate the ideal of perfection.

The problem of peer disagreement is to explain how you should respond when you and a peer have the same evidence bearing on some proposition and are equally competent epistemic agents, yet have reached opposite conclusions about. According to Christensen's Independence Thesis, in assessing the effect of your peer's disagreement, you must not rely on the reasoning behind your initial belief. I note that ‘the reasoning behind your initial belief’ can be given either a token or type reading. I argue (...) that the type reading is false, but the token reading is extremely weak. (shrink)
