This paper argues that the most famous objection to backward time travel can carry no weight. In its classic form, the objection is that backward time travel entails the occurrence of impossible things, such as auto-infanticide—and hence is itself impossible. David Lewis has rebutted the classic version of the objection: auto-infanticide is prevented by coincidences, such as time travellers slipping on banana peels as they attempt to murder their younger selves. I focus on Paul Horwich‘s more recent version of the (...) objection, according to which backward time travel entails not impossible things, but improbable ones—such as the string of slips on banana peels that would be required to stop a determined auto-infanticidal maniac from murdering her younger self—and hence is itself highly improbable. I argue that backward time travel does not entail unusual numbers of coincidences; and that, even if it did, that would not render its occurrence unlikely. (shrink)

A world in which time travel into the past occurred would seem like a most strange world. Nicholas Smith, however, in his ‘Bananas Enough for Time Travel’, argues that time travel is not so strange as we think. In particular, he argues against what he views as the main reason time travel worlds seem so strange – the claim that time travel entails unusual numbers of coincidences. I shall argue that Smith's argument for rejecting the claim is inadequate. Hence, (...) the debate over the consequences of the coincidences of time travel cannot be avoided by denying the coincidences themselves. (shrink)

Taking into account the symbolic universe of the civic-military dictatorships of the Southern Cone as a context, this article seeks to reflect on the aesthetic and political implications of the figuration of the diva in the performance of local artists, through the case of Ney Matogrosso and his reappropriations of Carmen Miranda. From a feminist theoretical orientation in a postcolonial key, it is possible to suspect that the figuration of the diva is strategically infiltrated in its performance, from a network (...) of aesthetic superposition that aim to destabilize the dominant symbolic order, rendering porous the boundaries between masculine and feminine, the political and the spectacular. The relevance of this study lies not only in the attempt to shed light on this “parody tinsel gesture” from its possible aesthetic effects, but also to contribute to the unexplored field of its political implications in the Latin American context.

In lieu of an abstract, here is a brief excerpt of the content:Slipping on Banana Peels, Tumbling into WellsPhilosophy and ComedyPaul A. Kottman (bio)Alenka Zupančič. The Odd One In: On Comedy. Cambridge, MA: MIT P, 2008.[T]he philosopher... is the jest, not only of Thracian handmaids but of the general herd, tumbling into wells and every sort of disaster through his inexperience [hupo apeirias].—Plato, Theaetetus 174cWhy stop philosophy’s most precious intrinsic comedy when it comes to comedy?—Alenka Zupančič, The Odd One In1“Comedy,” (...) writes Alenka Zupančič in The Odd One In, “draws our attention to the fact that something of our life lives on its own as we speak, that is to say, at any moment of our life” [218]. Reelaborating some of Jacques Lacan’s formulations regarding comedy, drive, and desire, Zupančič clarifies that this “something” is the “Real of human desire”— namely, “the incongruence of the reality of desire and drive with all those (also quite factual) outlines that determine our supposedly realistic reality” [218]. This extrapolation from Lacan frames Zupančič’s views on comedy and its subversive character; but it is her unique engagement with G. W. F. Hegel’s remarks on comedy—particularly the sections of the Phenomenology of Spirit in which Hegel tracks the passage from the Comedy of Aristophanes to Christianity—that give a distinctive arc to Zupančič’s highly original and generative approach to comedy and its subversive character. In this review essay, I will draw attention to some of the most original aspects of this critical appropriation of Hegel, while highlighting key elements of the text’s argumentative trajectory. Toward the end of this essay, I will also suggest ways that Hegel’s speculative remarks, which see the comic figure as symptomatic of a community that is not yet conscious of itself as such, might allow us to put into question some of Zupančič’s central claims regarding the subversive nature of both comedy and her own critical intervention.Zupančič’s reflections on comedy—which are not only innovative, but also delightfully readable—merit, in their own right, the attention of anyone interested in the intersection of literature, philosophy, and contemporary culture; but her text is all the more significant in light of the oft-remarked rarity of sustained philosophical reflections on comedy. Although there are a number of books on comedy as a literary genre, philosophical studies of comedy are surprisingly rare.1 Henri Bergson’s Le rire (published in 1900) [End Page 3] is perhaps the most well known. More recently, Simon Critchley has written about laughter, wit, and jokes in On Humour. Perhaps the most comprehensive philosophical account of comedy to date—Agnes Heller’s Immortal Comedy: The Comic Phenomenon in Art, Literature and Life (2005)—was published only three years before The Odd One In.2In contrast to Heller’s work, which offers a philosophical account of a variety of comic works and genres, and unlike these other earlier studies, which deal with the poetics of comedy and related phenomena such as laughter or jokes, Zupančič does not approach comedy as an object of inquiry that might be analyzed by philosophical categories or methods, nor even as a phenomenon that is extrinsic to philosophy. Instead, she sees comedy and philosophy as intrinsic to one another, such that the fate of philosophical activity is tied to the fate of the comical. In assessing Zupančič’s claims, therefore, I will strive less for a summary catalogue of the claims presented in the book than for a reelaboration of what I take to be her most provocative and important assertions regarding what she calls the “critical edge” shared by both philosophy and comedy [Zupančič 9].The Odd One In is the eighth title in the series Short Circuits, edited by Slavoj Žižek, in relation to whose writings Zupančič’s text clearly stands in intellectual and stylistic propinquity. (Žižek himself might be taken as a prime figure in whom comic and philosophical practices, in Zupančič’s sense, coincide.) The book opens and closes with a reminder that we too often mistake the subversive side of comedy for “a consolation... (shrink)

Fair trade bananas are the latest inan increasing array of commodities that are beingpromoted by various organizations in an effort tocreate alternative production and consumption patternsto the environmentally destructive and sociallyinequitable patterns inherent in traditionalproduction and trade systems. Fair trade is touted asa strategy to achieve more sustainable developmentthrough linking environmentally and socially consciousconsumers in the North with producers pursuingenvironmentally sound and socially just productionpractices in the South. Promotion of fair tradebananas in Europe has achieved impressive initialgains on the (...) consumer end of the commodity chain,capturing 10 percent or more of the banana trade inseveral countries. Yet in spite of these gains, thefair trade banana initiative appears to beencountering serious obstacles to its further success.We argue that the primary challenge in creating atruly alternative trade in bananas stems from thedifficulties of upholding rigorous social andenvironmental standards in the face of increasinginroads into fair trade markets by transnationalcorporations producing under less rigorous conditions.We then develop a series of options for strengtheningfair trade banana initiatives in both Europe and NorthAmerica. We conclude by arguing that the case ofbananas illuminates the general question of how toachieve more progressive and sustainable productionand consumption systems within a global system thatdrives production and consumption toward greaterintegration and homogenization under the control oftransnational corporations.

Daniel Dennett has argued that consciousness can be satisfactorily accounted for in terms of physical entities and processes. In some of his most recent publications, he has made this case by casting doubts on purely conceptual thought experiments and proposing his own thought experiments to "pump" the intuition that consciousness can be physical. In this paper, I will summarize Dennett's recent defenses of physicalism, followed by a careful critique of his position. The critique presses two flaws in Dennett's defense of (...) physicalism. First, I will rebut his case against the traditional conceptual arguments against physicalism. Second, I will present some empirical grounds for thinking that a crucial move in the argument against physicalism is well-supported. For someone, like Dennett, who finds conceptual arguments dubious, the empirical findings make it exceptionally difficult to deny the anti-physicalist argument. (shrink)

Fair trade banana farming in the Windward Islands of the Caribbean has emerged since the late 1990s in response to a crisis. Rulings by the World Trade Organization ended a longstanding trade dispute between the US and the EU by eliminating a system of preferential access of Windward Island bananas to the UK market. What followed was a period of rapid decline in banana exports from these small islands and a widespread abandonment of banana cultivation. Those banana farmers who (...) remain are now primarily fair trade producers. Fair trade banana production in the Windward Islands can thus be conceived as a survival strategy that farmers have developed in response to a particular instance of neoliberal globalization. The paper considers this response especially in the context of recent fieldwork on the island of St. Vincent. In light of contributions by several scholars who have drawn upon the work of Polanyi to understand both fair trade and resistance to neoliberalism, fair trade banana production in the Windward Islands appears significant not only as a local survival strategy, but also as part of a larger countermovement that resists neoliberal globalization.

As the market share of Fair Trade food products in countries of the North grows, understanding consumer preferences with regard to this recent label is becoming increasingly important. This article reports on a test of the consistency of consumers' stated preferences, for which a survey was conducted at the place and time of actual purchase decisions. The aim of the survey was to further improve the understanding of consumers' stated motivations for buying 'Fair Trade' and 'organic Fair Trade' bananas (...) in Switzerland. Hypothetical questions with double dichotomous choices were used to compare two types of bananas - conventional and labelled - and to assess the average stated willingness-to-pay (WTP) for Fair Trade-labelled bananas. The results show that Fair Trade is largely accepted in Switzerland and that the premium for purchasing such products is influenced by age, the number of young children and the perception of the Fair Trade label. I then used a comparative test of field observations and stated preferences for bananas to measure inconsistency in choices. This comparison reveals that less than one-fifth of the answers are in principle inconsistent. These results point to the importance of confidence in the Fair Trade labels if consumers' purchases are to increase. (shrink)

From Basil Fawlty, The Little Tramp and Frank Spencer; to Jim Carey, Andy Kaufman and Rowan Atkinson... comedy characters and comic actors have proved useful lenses for exploring—and exposing—humor’s cultural and political significance. Both performing as well as chastising cultural values, ideas and beliefs, the comic character gives a unique insight into latent forms of social exclusion that, in many instances, can only ever be approached through the comic form. It is in examining this comic form that this paper will (...) consider how the ‘comedy character’ presents a unique, subversive significance. Drawing from Lacanian conceptions of the subject and television ‘sitcom’ examples, the emancipatory potential of the comedy character will be used to criticize the predominance of irony and satire in comic displays. Indeed, while funny, it will be argued that such comic examples underscore a deprivative cynicism within comedy and humor. Countering this, it will be argued that a Lacanian conception of the subject can profer a comic efficacy that not only reveals how our social orders are inherently inconsistent and open to subversive redefinition, but that these very inconsistencies are also echoed in the subject, and, in particular, the ‘true comedy character’.

Certification of banana plantations is widely used as a device for protecting and improving socio-economic conditions of wageworkers, including their incomes, working conditions and—increasingly—voice [related to labour relations and workplace representation]. However, to date, evidence about the effectiveness of certification in these domains is scarce. We collected detailed field data on economic benefits for improving household income, social benefits for labour practices, and the voice of wageworkers focusing on identity and identification issues amongst wageworkers at Fairtrade certified banana plantations and (...) comparable, non-certified plantations in the Dominican Republic. We used different types of regression models to identify significant relationships. Econometrical analysis of survey results complemented by field observations and outcomes from in-depth stakeholder interviews indicate that the impact of Fairtrade certification on wageworkers’ economic benefits is rather limited. However, the impact on the voice of wageworkers, is more evident. On Fairtrade certified plantations workers are more satisfied with the course of life and better represented. Thus while the additional value of Fairtrade certification on primary wages seems limited, Fairtrade has relevant positive effects on the labour force, particularly by delivering in-kind benefits, offering a sense of job-security, improving voice and enabling private savings. Benefits of certification, but also other interventions with a similar purpose, might therefore not be discerned in terms of economic benefits such as wages or basic labour conditions that are under direct control of national law, but they should be identified in terms of social benefits and improved norms of conduct for wageworker engagement.

In this introduction to the first installment of the Common Knowledge symposium “Peace by Other Means,” the journal's editor questions the assumptions that underwrite standard approaches in the social sciences to the issue of how non-state, tribal societies have dealt with matters of war and peace. He in particular examines and finds wanting the approach that Jared Diamond takes in The World until Yesterday: What Can We Learn from Traditional Societies?. Whereas Diamond's theme is that modern states can learn much (...) about many things from traditional hunter-gatherer societies, with respect to peacemaking and peace-keeping he finds traditional societies distinctly inferior, and the arguments by which he reaches this conclusion are tautological and also beg the question. This prefatory essay explains that “Peace by Other Means” will analyze and detail non-Western and premodern European means of keeping peace that modern theorists of conflict resolution are reluctant to credit or incompetent to assess.

During the last 10 years or so, a number of corporate social responsibility (CSR) initiatives have been introduced in global supply chains, which aim to improve the conditions of workers engaged in producing goods for export. This article discusses the observations of CSR in practice in the Costa Rican-United Kingdom (UK) banana chain. The banana chain makes for an interesting case study because there are dominant corporate actors at each end who are in a position to influence the conditions experienced (...) by workers on banana plantations. At the top of the chain there are four major UK supermarket groups who control access to the retail market and as selfappointed guardians of consumer interest are demanding that producers adopt more socially responsible practices. At the other end, banana production is highly integrated and controlled by three large North American agri-businesses who have developed their own social and environmental certification programmes. Costa Rica also makes for an interesting country to locate the study as it has a tradition of state-led policies to protect worker rights. Yet, in spite of CSR commitments made by both supermarkets and producers that emphasise health and safety and the country's established Labour Law, this article shows that there are problems for workers when they are forced to meet demanding production schedules. Furthermore, it suggests that whilst supermarkets continue to drive down consumer prices and put pressure on producers to reduce costs, a downward spiral of working conditions is created regardless of the CSR policies in place. However, this article also identifies that changes to supermarket behaviour is possible when consumer trust is at stake. (shrink)

The aim of this paper is to investigate the role of water stress on plants production. We propose a mathematical model for the dynamics growth of plants that takes into account the concentration of available water in the soil, water stress, plant production and plants compensation. Sensitivity analysis of the model has been performed in order to determine the impact of related parameters on the dynamics growth of plants. We present the theoretical analysis of the model with and without water (...) stress. More precisely, we show that the full model is well-posedness. For each model, we compute the trivial equilibria and derive two thresholds parameters that determine the outcome of water stress within a plantation. Further, we perform numerical simulation on the case of banana-plantain simulations to support the theory. We found that the Hopf bifurcation occurs for a specific value of the water absorption rate of unstressed plants. The impact of the water stress on the banana-plantain production is also numerically investigated. After, the role of the water stress on the plant production is numerically investigated. We found that the water stress can cause about 68.16% of loss of banana-plantain production within a plantation with 1600 rejets initially planted. This suggests that climate change plays a detrimental role on banana-plantains production. (shrink)

Global concerns over environmental and social issues in agrifood value chains have increased and are reflected in a number of voluntary sustainability standards and regulatory initiatives. However, these initiatives are often based on poor knowledge of production realities, creating a disconnect between producing and consuming countries. Through narrative analysis, this paper reveals asymmetries in the responsibilities of the various actors participating in Ecuadorian banana value chains, providing clear problem- and solution-framings. Despite the broad range of actors interviewed, our analysis reveals (...) convergence in two main narratives that reflect asymmetries amongst local actors in terms of their ability to participate, ability to maintain participation, and adaptation strategies in view of changing external factors. One narrative relates to sustainability adaptations, the cost of which is not shared among all value chain actors. This is combined with a downward trend in the price of bananas and the lack of a differentiated price to account for losses and costs arising from increasing sustainability standards. Another narrative reflects a value chain structure that threatens small-farm survival. It highlights the urgency of protecting small-farm activity by enforcing national regulation and developing new market segments/models that understand small-scale producer reality. Study results show that the multitude of standards is not seen as beneficial and that downstream actors rather wish for common minimum standards to reduce business costs. Compatibility between standards and local realities should be a priority for global sustainability standards adoption. Building on the problems and solution-framings of local value chain links, we give voice to local actors, and link their perceptions to existing literature and discursive politics while contributing to social transparency and addressing the democratic deficit in agrifood value chains.

How will the adoption of genetically modified staple crops reconfigure labor processes in Sub-Saharan Africa? This article focuses on Uganda, where GM varieties of matooke, the country’s primary carbohydrate staple, are expected to be commercialized within the next few years. The paper draws on survey data and focus groups with a random sample of over one hundred and fifty growers to investigate the potential ways a variety engineered to be resistant to banana bacterial wilt might impact labor dynamics. A BBW (...) resistant GM variety will displace labor currently allocated to disease prevention and control, and increase the labor required for harvesting higher yields. How farmers can address the need for more harvesting labor varies significantly according to region. In the southwestern highlands, producers can increase their portion of hired labor. In the central and eastern regions, where farms tend to be smaller and subsistence-oriented, farmers are more likely to intensify their use of unpaid family labor, particularly that of wives. Hence, while GM technology may result in increased yields for small-scale farmers in Uganda, this is likely to come at the cost of intensifying the agricultural labor burdens of women in the central and eastern region.

The Fair Trade movement seeks to alter conventional trade relations through a system of social and environmental standards, certification, and labels designed to help shorten the social distance between consumers in the North and producers in the South. The strategy is based on working both ‘in and against’ the same global capitalist market that it hopes to alter, raising questions about if and how Fair Trade initiatives exhibit counter-hegemonic potential to transform the conventional agro-food system. This paper considers the multiple (...) levels at which Fair Trade alternatives operate to identify the different forms of social action that the movement engages with, and to clarify where the movement’s counter-hegemonic potentials are being realized. I suggest the Fair Trade movement is most successful in encouraging consumers and producers to commit acts of resistance and in supporting redistributive action that shifts resources from North to South. Up to now, however, Fair Trade alternatives appear to hold only a theoretical potential to provoke transformative change in the agro-food system. A reconceptualization of the Fair Trade model and how it is implemented could allow it to manifest more of its implicit, oppositional promise. (shrink)

Radopholus Similis or burrowing nematode, is one of the most damaging and widespread nematodes attacking bananas, causing toppling or blackhead disease. A mathematical model for the population dynamics of R. Similis is considered, with the aim of investigating the impact of climatic factors on the growth of R. Similis. In this paper, based on the life cycle of R. Similis, we first propose a mathematical model to study and control the population dynamics of this banana pest. We show also (...) how control terms based on biological and chemical controls can be integrated to reduce the population of R. Similis within banana-plantain roots. Sensitivity analysis was performed to show the most important parameters of the model. We present the theoretical analysis of the model.

After, we extend the proposed model by taking account climatic factors that influence the growth of this pest. Biological and chemical controls are now introduced through impulsive equations. Threshold and equilibria are obtained and global stabilities have been studied. The theoretical results are supported by numerical simulations. Numerical results of model with biological and chemical controls reveal that biological methods are more effective than chemical methods. We also found that the month February is the best time to apply these controls. (shrink)

This paper is trying to show that it is not possible to use the Knowledge argument as independent evidence for the form of non-reductionism the Modal argument argues for. To show this, Jackson's famous 'Mary' thought experiment is imagined in a zombie world. This leads to the result that there are many problems in the Mary experiment, which cannot have anything to do with phenomenal Qualia, because the Zombie-Mary would encounter them as well, and once all these problems are accounted (...) for, it is no longer clear whether a Zombie-Mary is conceivable at all. Finally, an alternative explanation for the strong non-reductive intuitions of the Mary experiment is discussed. (shrink)

Several initiatives by the Government of Uganda, Research Institutes and CGIAR centers have promoted the use of tissue culture banana technology as an effective means of providing clean planting material to reduce the spread of Banana Xanthomonas wilt but its uptake is still low. We examine factors that constrain uptake of tissue culture banana planting materials in central Uganda by considering the cultural context of banana cultivation. Data were collected using eight focus group discussions involving 64 banana farmers and 10 (...) key informant interviews and subjected to thematic analysis. Results showed that banana cultivars in the study communities were important for food, cultural practices and medicine. Cultivars supplied through TC were based on commercial considerations focusing on market value and household income and insufficient attention was given to their cultural importance. Farmers regard banana from TC planting material to be incompatible with their tastes and preferences for traditional food and drinks, culture and medicine. Furthermore, the plantlets are perceived as complicated to use, and farmers report requiring more knowledge and information on how to plant and maintain the plantlets on-farm. In these aspects, TC planting material does not align with cultural values linked to societal welfare. Future efforts aimed at controlling pests and diseases would benefit from more location-specific and holistic approaches that integrate cultural dimensions alongside planting material hygiene, quality and vigor.

Abstract. In this paper I shall take an inferential approach to legality (legal validity), and consider how the legality of a norm can be inferred, and what can be inferred from it. In particular, I shall analyse legality policies, namely, conditionals conferring the quality of legality upon norms having certain properties, and I shall examine to what extent such conditionals need to be positivistic, so that legality is only dependant on social facts. Finally, I shall consider how legality is transmitted (...) from norm to norm and whether the ultimate legality policies (the rules of recognition) of a legal system need to be constituted by social facts.

I argue against a class of philosophical views of color perception, especially insofar as such views posit the existence of color sensations. I argue against the need to posit such nonconceptual mental intermediaries between the stimulus and the eventual conceptualized perceptual judgment. Central to my arguments are considerations of certain color illusions. Such illusions are best explained by reference to high-level, conceptualized knowledge concerning, for example, object identity, likely lighting conditions, and material composition of the distal stimulus. Such explanations obviate (...) the need to appeal to nonconceputal mental links in the causal chains eventuating in conceptualized color discriminations. (shrink)

Constructivist pedagogies cannot achieve their critical thinking ambitions. Constructivism, and constructivist epistemological presuppositions, actively thwarts the critical thinking process. Using Wittgenstein's private language argument, this paper argues that corrective mechanisms—the ability to correct a student's propositions and cognitions against the background of a shared, knowable world—are indispensible to critical thinking. This paper provides concrete examples of actual constructivist practice and shows how a particular constructivist classroom exercise can be modified to incorporate critical thinking elements as detailed by the American Philosophical (...) Association. Finally, the paper states the significance of these arguments, particularly as they extend from the educational arena into the public and governmental domains. (shrink)

En este artículo se analizan los límites de la solidaridad desde el descentramiento de los protagonistas mestizos en Limón Reggae, de la costarricense Anacristina Rossi (2007), y Big Banana, del hondureño Roberto Quesada (2000).

Mientras Limón Reggae explora una solidaridad de carácter político-estructural, tanto en Costa Rica como en Estados Unidos, así como la posibilidad (...) de una relación amorosa interracial, Big Banana se enfoca en la solidaridad por empatía a través de la relación entre Eduardo y Mairena en territorio estadounidense, problematizando así la posibilidad de reinvención identitaria en ese “tercer espacio”. Ninguno de los dos textos se atreve a presentar una solución simplista u homogénea para la convivencia, por lo que los dos grupos, finalmente, permanecen separados. Ambas recalcan la importancia del lugar de enunciación y, deesta manera, evitan caer en las falacias de las ficciones de solidaridad que se pierden en su propia fantasía de solidaridad. (shrink)

Sales in supermarkets have contributed greatly to growth in Fairtrade, but the literature suggests there may be tensions between Fairtrade principles and the commercial practices which characterise UK supermarket value chains. This article explores these tensions through an analysis of supermarket value chains for Fairtrade coffee, cocoa, bananas and fresh fruit. It finds considerable variation in UK supermarket approaches in terms of scale and scope of commitment to Fairtrade and in the nature of relationships with Fairtrade suppliers. In some (...) cases supermarket involvement has the potential both to expand and deepen the impact of Fairtrade, whereas in others it threatens to undermine the ability of Fairtrade to support long-term processes of development. The findings indicate that a more nuanced approach to supermarket Fairtrade is required, with recommendations for actions that could be taken to maximise the opportunities and minimise the risks.

An individual has a theory of mind if he imputes mental states to himself and others. A system of inferences of this kind is properly viewed as a theory because such states are not directly observable, and the system can be used to make predictions about the behavior of others. As to the mental states the chimpanzee may infer, consider those inferred by our own species, for example, purpose or intention, as well as knowledge, belief, thinking, doubt, guessing, pretending, liking, (...) and so forth. To determine whether or not the chimpanzee infers states of this kind, we showed an adult chimpanzee a series of videotaped scenes of a human actor struggling with a variety of problems. Some problems were simple, involving inaccessible food as in the original Kohler problems; others were more complex, involving an actor unable to extricate himself from a locked cage, shivering because of a malfunctioning heater, or unable to play a phonograph because it was unplugged. With each videotape the chimpanzee was given several photographs, one a solution to the problem, such as a stick for the inaccessible bananas, a key for the locked up actor, a lit wick for the malfunctioning heater. The chimpanzee's consistent choice of the correct photographs can be understood by assuming that the animal recognized the videotape as representing a problem, understood the actor's purpose, and chose alternatives compatible with that purpose.

Take this banana. It is now yellow, and when I bought it yesterday it was green. How can a single object be both green all over and yellow all over without contradiction? It is, of course, the passage of time which dissolves the contradiction, but how is this possible? How can a banana ripen? These questions raise the problem of change. The problem is sometimes called the problem of temporary intrinsics, but, as I shall explain below, this emphasis on intrinsic (...) properties is misleading. For my more recent thoughts in this area, please see my 'David Lewis on Persistence' (2015). (shrink)

I can imagine a banana to be a phone receiver. I can also imagine the flapping of my arms to be flying. So it is possible to imagine one thing to be another—at least for some types of ‘things’.

This claim will have some important consequences beyond the philosophy of imagination, for example, for some accounts of depiction. (shrink)

Many of the items that humans consume are produced in ways that involve serious harms to persons. Familiar examples include the harms involved in the extraction and trade of conflict minerals (e.g. coltan, diamonds), the acquisition and import of non- fair trade produce (e.g. coffee, chocolate, bananas, rice), and the manufacture of goods in sweatshops (e.g. clothing, sporting equipment). In addition, consumption of certain goods (significantly fossil fuels and the products of the agricultural industry) involves harm to the environment, (...) to future persons, and to current persons in low-lying and developing countries, by way of their impacts on climate change. When it comes to such large-scale harms, it's easy for the individual to feel helpless. Even if she sincerely wishes things were otherwise, she may wonder what she could possibly do to make them so. In this paper I briefly explore several promising avenues for generating duties in individuals to consume ethically, and develop one in particular: that an individual ought to signal her commitments to others, as a first step in collectivizing to act against unjust global labour practices.

The question as to whether there are mathematical explanations of physical phenomena has recently received a great deal of attention in the literature. The answer is potentially relevant for the ontology of mathematics; if affirmative, it would support a new version of the indispensability argument for mathematical realism.

Second, in an attempt to strengthen the (...) realist position, I propose a new type of example, drawing on probabilistic considerations. 1 Introduction2 Mathematical Explanations2.1 ‘Simplicity’3 An Average Story: The Banana Game3.1 Some clarifications3.2 Hopes and troubles for the nominalist3.3 New hopes?3.4 New troubles4 Conclusion.

There is a sense in which it is trivial to say that one accepts intention- (or convention-) based semantics.[2] For if what is meant by this claim is simply that there is an important respect in which words and sentences have meaning (either at all or the particular meanings that they have in any given natural language) due to the fact that they are used, in the way they are, by intentional agents (i.e. speakers), then it seems no one should (...) disagree. For imagine a possible world where there are physical things which share the shape and form of words of English or Japanese, or the acoustic properties of sentences of Finnish or Arapaho, yet where there are no intentional agents (or where any remaining intentional agents don’t use language). In such a world, it seems clear that these physical objects, which are only superficially language-like, will lack all meaning. Furthermore, it seems that questions of particular meaning are also settled by the conventions of intentional language users: it’s nothing more than convention which makes the concatenation of letters ‘a’^‘p’^‘p’^‘l’^‘e’ mean apple, rather than banana, in English.[3] So, understood as the minimal claim that intentional agents, who have a practice of using certain physical objects (written words, sounds, hand gestures, etc) to communicate certain thoughts, are a prerequisite for linguistic meaning, the idea that semantics is based on both intention and convention seems indisputable. I will label a theory which recognises this preconditional role for speaker intentions an A-style intention-based semantics and we will explore one such account in §1. (shrink)
