In this article, agrofuels are examined in the context of the world food price crisis and the “food sovereignty” proposal for addressing the crisis. Both short- and long-term causes of the crisis are examined, and while agrofuels are presently not a prime causal factor they are clearly contraindicated by the crisis. Food sovereignty, including a moratorium on agrofuels, is argued to offer the best option for managing the crisis.

The 1989 collapse of trade relations with the former socialist bloc plunged Cuba into an economic and food crisis. Cuban farmers, scientists, and planners have responded with alternative agricultural technology to make up for imported food and Green Revolution inputs that are no longer available. A review of Cuban experience to date with biological pest control practices shows that, on the one hand, significant progress has been made that may serve as a model for other countries, while, on the other (...) hand, there still remains a long way to go if Cuba is to create a truly sustainable agriculture. It is essential that we understand the Cuban case if we are to be concerned about ethical issues in biological control. The apparent ability of Cuba to overcome a food crisis without significant use of pesticides stretches our concept of the possible. It thus helps refute the most common argument – that we couldn't “feed the hungry” without pesticides – against taking the “ethical” position in real-world pest management policy debates. (shrink)

In this paper I propose a series of hypotheses for further study that are related to potential negative impacts of non-traditional export agriculture (NTEA) on peasantfarmers in Central America. International lenders and donor agencies are promoting this diversification of agricultural exports as part of structural adjustment programs in the region, in order to increase foreign exchange earnings and raise the incomes of the rural poor.There is growing evidence, however, that the impact on the rural poor may not be favorable. I (...) argue that because NTEA can introduce powerful economies of scale, it is likely to accelerate social differentiation in the countryside and expel large numbers of peasant farmers from their lands. In this sense NTEA may be similar to previous export ‘booms,’ leading to rapid intensification of social instability and conflict in an already troubled region. This raises the serious question of the long term sustainability of this development strategy.There is a shortage of published studies that directly address these issues, making further work essential for the adequate review of NTEA policies. I formulate six testable hypotheses based on the economies of scale associated with NTEA. Each is related to a resource essential for successful agricultural production: land; credit; prices, costs, and subsidies; technology; technical assistance; and markets. I suggest that as NTEA grows, small farmer access to each is reduced, eventually making peasant production for domestic consumption an unviable alternative, while those who venture into NTEA encounter unacceptable levels of risk.

Industry and mainstream research and policy institutions often suggest that transgenic crop varieties can raise the productivity of poor third world farmers, feed the hungry, and reduce poverty. These claims are critically evaluated by examining global-hunger data, the constraints that affect the productivity of small farmers in the third world, and the factors that explain their poverty. No significant role is found for crop genetics in determining hunger, productivity, or poverty, casting doubt on the ability of new transgenic crop varieties (...) produced by genetic engineering to address these problems. An examination of the special risks these varieties pose for poor farmers in the complex, diverse, and risk-prone environments that characterize peasant agriculture on a global scale suggests that transgenic crop varieties are likely to be more of hindrance than a help to the advancement of poor farmers.

The Cuban government has undertaken the task of transforming insect pest and weed management from conventional to organic and more sustainable approaches on a nationwide basis. This paper addresses past programs and current major areas of research and implementation as well as provides examples of programs in insect and weed management. Topics covered include the newly constructed network of Centers for the Reproduction of Entomophages and Entomopathogens (CREEs), which provide the infrastructure for the implementation of biological control on state, cooperative, (...) and private farm operations. CREE programs include the mass rearing and release of Trichogramma spp. to manage insect pests of cassava, tobacco, sugarcane, and improved pasture. The entomopathogens, Bacillus thuringiensis, Beauveria bassiana, Metarhizium anisopliae, and Verticillium lecanii, are being mass produced in the CREEs and applied to control a number of key insect pests. A traditional method employed by peasant farmers of using the predatory ant Pheidole megacephala (Fabricius) in the biological control of sweetpotato and banana insect pests has been further developed and implemented. Efforts are underway to rear nematode species that attack insect pests and identify plant extracts with insecticidal qualities as potential management tools. Weed management has moved away from dependence on herbicides and toward alternative techniques that include weed suppression based on rotation schemes, limited use of selective herbicides, and new tillage equipment and practices.

Social movements are using education to generate critical consciousness regarding the social and environmental unsustainability of the current food system, and advocate for agroecological production. In this article, we explore results from a cross-case analysis of six social movements that are using education as a strategy to advance food sovereignty. We conducted participatory research with diverse rural and urban social movements in the United States, Brazil, Cuba, Bolivia, and Mexico, which are each educating for food sovereignty. We synthesize insights from (...) critical food systems education and the political ecology of education in analyzing these cases. We compare the thematic similarities and difference between these movements’ education initiatives in terms of their emergence, initial goals, expansion and institutionalization, relationship to the state, theoretical inspirations, pedagogical approach, educational topics, approach to student research, and outcomes. Among these thematic areas, we find that student-centered research on competing forms of production is an integral way to advance critical consciousness about the food system and the political potential of agroecological alternatives. However, what counts, as success in these programs, is highly case-dependent. For engaged scholars committed to advancing education for food sovereignty, it is essential to reflect upon the lessons learned and challenges faced by these movements. (shrink)

An emergent contradiction in the contemporary development of biological control is that of the prevalence of the substitution of periodic releases of natural enemies for chemical insecticides and the dominance of biotechnologically developed transgenic crops. Input substitution leaves in place the monoculture nature of agroecosystems, which in itself is a key factor in encouraging pest problems. Biotechnology, now under corporate control, creates more dependency and can potentially lead to Bt resistance, thus excluding from the market a key biopesticide. Approaches for (...) putting back biological control into the hands of farmers (from artesanal biotechnology for grassroots biopesticide production Cuban style to farmer-to-farmer IPM networks, etc.) have been developed as a way to create a farmer centered approach to biological control.

Having lost 73% of its purchasing power and 42% of it gross national product since the fall of the Soviet Union, Cuba faces a crisis with the modern agricultural system it had developed over the past 30 years. The response has been to put an alternative model into practice. The successes and problems associated with this model are discussed.

Urban agriculture in Cuba has rapidly become a significant source of fresh produce for the urban and suburban populations. A large number of urban gardens in Havana and other major cities have emerged as a grassroots movement in response to the crisis brought about by the loss of trade, with the collapse of the socialist bloc in 1989. These gardens are helping to stabilize the supply of fresh produce to Cuba's urban centers. During 1996, Havana's urban farms provided the city's (...) urban population with 8,500 tons of agricultural produce, 4 million dozens of flowers, 7.5 million eggs, and 3,650 tons of meat. This system of urban agriculture, composed of about 8,000 gardens nationwide has been developed and managed along agroecological principles, which eliminate the use of synthetic chemical pesticides and fertilizers, emphasizing diversification, recycling, and the use of local resources. This article explores the systems utilized by Cuba's urban farmers, and the impact that this movement has had on Cuban food security. (shrink)

It is argued that causal understanding originates in experiences of acting on objects. Such experiences have consistent features that can be used as clues to causal identification and judgment. These are singular clues, meaning that they can be detected in single instances. A catalog of 14 singular clues is proposed. The clues function as heuristics for generating causal judgments under uncertainty and are a pervasive source of bias in causal judgment. More sophisticated clues such as mechanism clues and repeated interventions (...) are derived from the 14. Research on the use of empirical information and conditional probabilities to identify causes has used scenarios in which several of the clues are present, and the use of empirical association information for causal judgment depends on the presence of singular clues. It is the singular clues and their origin that are basic to causal understanding, not multiple instance clues such as empirical association, contingency, and conditional probabilities. (shrink)

Research has found that children possess a broad bias in favor of teleological - or purpose-based - explanations of natural phenomena. The current two experiments explored whether adults implicitly possess a similar bias. In Study 1, undergraduates judged a series of statements as "good" or "bad" explanations for why different phenomena occur. Judgments occurred in one of three conditions: fast speeded, moderately speeded, or unspeeded. Participants in speeded conditions judged significantly more scientifically unwarranted teleological explanations as correct, but were not (...) more error-prone on control items. Study 2 extended these findings by examining the relationship between different aspects of adults’ "promiscuous teleology" and other variables such as scientific knowledge, religious beliefs, and inhibitory control. Implications of these findings for scientific literacy are discussed. (shrink)

Berkeley’s likeness principle is the claim that “an idea can be like nothing but an idea”. The likeness principle is intended to undermine representationalism: the view (that Berkeley attributes to thinkers like Descartes and Locke) that all human knowledge is mediated by ideas in the mind which represent material objects. Yet, Berkeley appears to leave the likeness principle unargued for. This has led to several attempts to explain why Berkeley accepts it. In contrast to ‘metaphysical’ and ‘epistemological’ interpretations available in (...) the literature, in this paper I defend a ‘conceptual’ interpretation. I argue that Berkeley accepts the likeness principle on the basis of (i) his commitment to the transparency of ideas, and (ii) his account of resemblance which he sets out in his works on vision. Thus, I provide an explanation for Berkeley’s reasons for accepting the likeness principle which, appropriately, focuses on his views concerning ideas and likeness. (shrink)

Margaret Macdonald was at the institutional heart of analytic philosophy in Britain in the mid-twentieth century. Yet, her views on the nature of philosophical theories diverge quite considerably from those of many of her contemporaries. In this paper, I focus on her 1953 article ‘Linguistic Philosophy and Perception’, a provocative paper in which Macdonald argues that the value of philosophical theories is more akin to that of poetry or art than science or mathematics. I do so for two reasons. First, (...) because it reveals just how far Macdonald’s meta- philosophical views diverged from those of many of her contemporaries. Second, because the discussion in LPP pre-empts recent literature on the nature of philosophical inquiry and the efficacy of philosophical arguments. Indeed, Macdonald’s paper is just as likely to provoke discussion today as it was in the 1950s. (shrink)

In my contribution to this Concise Collection on Margaret Cavendish, I focus on teaching Cavendish’s work in the context of philosophy (and, more specifically, Early Modern Philosophy). I have three aims. First, to explain why teaching women from philosophy’s history is crucially important to the discipline. Second, to outline my own reflections on teaching Cavendish’s philosophy. Third, to defend a specific claim about the benefits of teaching Cavendish to philosophy students; namely, that introducing biographical detail alongside philosophical ideas enriches the (...) learning experience.

This paper provides a philosophical evaluation of the concept of handedness prevalent but largely unspoken in the scientific literature. This literature defines handedness as the preference or ability to use one hand rather than the other across a range of common activities. Using the philosophical discipline of phenomenology, I articulate and critique this conceptualization of handedness. Phenomenology shows defining a concept of handedness by focusing on hand use leads to a right hand biased concept. I argue further that a phenomenological (...) model based in spatial orientation rather than hand use provides a more inclusive concept of handedness. (shrink)

William Molyneux was born in Dublin, studied in Trinity College Dublin, and was a founding member of the Dublin Philosophical Society (DPS), Ireland’s counterpart to the Royal Society in London. He was a central figure in the Irish intellectual milieu during the Early Modern period and – along with George Berkeley and Edmund Burke – is one of the best-known thinkers to have come out of that context and out of Irish thought more generally. In 1688, when Molyneux wrote the (...) letter to Locke in which he posed the now famous question about a man born blind made to see, he was an active member of the DPS and was on familiar terms with several other key figures in Irish philosophy at the time. For the most part, Irish thinkers in the seventeenth and eighteenth centuries answered “no” to Molyneux’s question of whether a blind man made to see could distinguish, by sight alone, between a cube and a sphere.

In der genannten Epoche werden Grundentscheidungen gefällt, welche die Fundamentalfrage der Philosophie, die Seinsfrage, in die Krisis führen, in den Nihilismus unter ontologischem, metaphysischem, epistemologischem, axiologischem Aspekt. Den Extrempositionen der Systemdenker Hegel, Schopenhauer und Schelling erwachsen in den Hegelkritikern Feuerbach, Br. Bauer, Marx und Stirner Kontrapositionen, die das Wahrheitsproblem der Beliebigkeit unterstellen. Kierkegaard klagt unter existentiellem Aspekt das Problem der Wahrheit ein. Nietzsche überholt durch Abschaffung der Wahrheit alle Positionen,was seinen Standort in der europäischen Denkgeschichte ausmacht und als Ergebnis der (...) problemgeschichtlichen Analysen zu charakterisieren ist. Die Rückgewinnung des Vernunfthorizontes setzen erst die Problemdenker N. Hartmann und M. Heidegger ins Werk durch kritische Erneuerung der Seinsfrage. (shrink)

At the end of the 1980s, Tennant invented a logical system that he called “intuitionistic relevant logic”. Now he calls this same system “Core logic.” In Section 1, by reference to the rules of natural deduction for $\mathbf{IR}$, I explain why $\mathbf{IR}$ is a relevant logic in a subtle way. Sections 2, 3, and 4 give three reasons to assert that $\mathbf{IR}$ cannot be a core logic.

Ce livre developpe une theorie de la negation qui rend compte de maniere complete des trois significations naturelles et fondamentales de la negation: rejet, absence et denegation. L'auteur adopte une theorie intuitionniste de la negation, parce qu'il considere que celle-ci offre une comprehension a la fois plus riche et plus fine de la negation que celle qui est donnee par la logique classique. La premiere partie de l'ouvrage commence avec des remarques qui relevent de la psychologie, la seconde traite de (...) la negation d'un point de vue logique, et la troisieme donne un apercu critique sur quelques metaphysiques de la negation, c'est-a-dire sur certains systemes philosophiques (ceux de Platon, de Spinoza et de Hegel) qui ont tire des consequences ontologiques a partir d'une definition specifique de la negation. Cette troisieme partie trouve une suite naturelle dans le commentaire des reflexions sur la question de la negation developpees par Spinoza (proposition 49 de la seconde partie de l'Ethique) et par Kant (Essai pour introduire en philosophie le concept de grandeur negative). Ces deux commentaires sont respectivement prolonges par une critique de l'analyse spinoziste de la negation et par l'explication de l'interet que presente la logique intuitionniste a la fois pour la comprehension de l'analyse kantienne et pour les lecons que l'on peut tirer du celebre carre des oppositions logiques, ou la negation joue un role crucial.
