The norms of simplicity, convenience, unfussiness, and self-control guide Diogenes the Cynic, Zeno of Citium, Chrysippus, Seneca, Musonius Rufus, Epictetus, and Marcus Aurelius in approaching food. These norms generate the precept that meat and dainties are luxuries, so Stoics should eschew them. Considerations of justice, environmental harm, anthropogenic global climate change, sustainability, food security, feminism, harm to animals, personal health, and public health lead contemporary Stoics to condemn the meat industrial complex, debunk carnism, and select low input, plant-based foods.

¶1 Charles Darwin began the last paragraph of The Origin of Species (1859) with a famous metaphor about life's diversity and ecological complexity: It is interesting to contemplate an entangled bank, clothed with many plants of many kinds, with birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth, and to reflect that these elaborately constructed forms, so different from each other, and dependent on each other in so complex a manner, have (...) all been produced by laws acting around us. He then begins the final sentence of the book with an equally famous statement: "There is grandeur in this view of life....". (shrink)

Absolute needs (as against instrumental needs) are independent of the ends, goals and purposes of personal agents. Against the view that the only needs are instrumental needs, David Wiggins and Garrett Thomson have defended absolute needs on the grounds that the verb ‘need’ has instrumental and absolute senses. While remaining neutral about it, this article does not adopt that approach. Instead, it suggests that there are absolute biological needs. The absolute nature of these needs is defended by appeal to: their (...) objectivity (as against mind-dependence); the universality of the phenomenon of needing across the plant and animal kingdoms; the impossibility that biological needs depend wholly upon the exercise of the abilities characteristic of personal agency; the contention that the possession of biological needs is prior to the possession of the abilities characteristic of personal agency. Finally, three philosophical usages of ‘normative’ are distinguished. On two of these, to describe a phenomenon or claim as ‘normative’ is to describe it as value-dependent. A description of a phenomenon or claim as ‘normative’ in the third sense does not entail such value-dependency, though it leaves open the possibility that value depends upon the phenomenon or upon the truth of the claim. It is argued that while survival needs (or claims about them) may well be normative in this third sense, they are normative in neither of the first two. Thus, the idea of absolute need is not inherently normative in either of the first two senses. (shrink)

The Genre Legong is a secular (balih-balihan) Balinese dance genre (Anon. 1971).[1] Though originally associated with the palace,[2] legong has long been performed in villages, especially at temple ceremonies, as well as at Balinese festivals of the arts. Since the 1920s, abridged versions of legong dances have featured in concerts organized for tourists and in overseas tours by Balinese orchestras. Indeed, the dance has become culturally emblematic, and its image is used to advertise Bali to the world. Traditionally, the dancers (...) are three young girls; the servant (condong), who dances a prelude, and two legong. All wear elaborate costumes of gilded cloth with ornate accessories and frangipani-crowned headdresses.[3] The core repertoire consists of about fifteen dances (some of which are now lost), ranging in their longest versions from thirty to sixty minutes. Some of these are narrative, while others are abstract or general representations of nature, birds, insects, or plants. Those that involve narratives are, nevertheless, highly stylized, and the presentation of the drama is always secondary to the beauty of the dance. The genre is regarded as a treasury of the movements for Balinese women’s dance, and no dancer’s training is complete if she lacks a solid grounding in legong. The dance is accompanied by a gamelan of twenty-five or more players.[4] Though the legong dance remains popular in areas of traditional strength, and despite efforts to revive it, it is generally in decline (Davies 2006).

Iowa's Rochester Cemetery is one of the most unusual and biodiverse prairies left in America, boasting more than 400 species of plants--337 of them native to the region--on its thirteen-and-a-half acres. Among them are fifteen massive white oaks that stood watch as the surrounding landscape was converted into farmland after Euro-American settlers arrived in the 1830s. The cemetery is the last resting place of these pioneers and their descendants, down to the present. Graves and wildflowers are scattered across the hills (...) that geologists consider sand dunes; these are held in place by the deep roots of the plants and people. Pioneer cemeteries have been recognized as important prairie remnants and seed banks ever since Aldo Leopold, another Iowa native, called attention to them in his landmark essays of the 1940s, as he developed the new field of ecological restoration. At Rochester Cemetery, the drama of the prairie's survival continues to this day, in a controversy that flares up as reliably as spring's shooting stars. To botanists across the country, this place is a pilgrimage site. To local residents, it is either a source of pride or a shameful weed lot. To the photographer and writer Stephen Longmire, it is a place where the stories of the rural Midwest are written on the land--a long exposure, extending back to the days when Meskwaki Indians camped nearby and wildfire held back the forest. In the creative tension between people and place, Rochester's prairie holds its native ground. Historic cemetery plantings grow wild among the native wildflowers, and bright plastic flowers decorate modern graves. In compelling photographs and prose, Longmire shows this patch of original Iowa to be a living record of all the land's uses since its settlement. (shrink)

Cornell University and Zamorano (ThePanamerican School of Agriculture) facilitatedworkshops that provided Honduran and Nicaraguanfarmers new experience with plant diseases and helpedfarmers assimilate information and identify diseasemanagement alternatives. After learning about thebiology of plant diseases, farmers were able toidentify disease problems in their field, enablingthem to use pesticides more selectively.

This paper argues that the English philosopher John Locke, who has normally been thought to have had only an amateurish interest in botany, was far more involved in the botanical science of his day than has previously been known. Through the presentation of new evidence deriving from Locke’s own herbarium, his manuscript notes, journal and correspondence, it is established that Locke made a modest contribution to early modern botany. It is shown that Locke had close and ongoing relations with the (...) Bobarts, keepers of the Oxford Botanic Garden, and that Locke distributed seeds and plant parts to other botanists, seeds of which the progeny almost certainly ended up in the most important herbaria of the period. Furthermore, it is claimed that the depth of Locke’s interest in and practice of botany has a direct bearing on our understanding of his views on the correct method of natural philosophy and on the interpretation of his well known discussion of the nature of species in Book III of his Essay concerning human understanding.

This paper gives a detailed analysis of four seed lists in the journals of John Locke. These lists provide a window into a fascinating open network of botanical exchange in the early 1680s which included two of the leading botanists of the day. Pierre Magnol of Montpellier and Jacob Bobart the Younger of Oxford. The provenance and significance of the lists are assessed in relation to the relevant extant herbaria and plant catalogues from the period. The lists and associated correspondence (...) provide the main evidence for Locke's own important, through modest contribution to early modern botany, a contribution which he would have regarded as a small part of the broader project of constructing a natural history of plants. They also provide a detailed case study of the sort of open and informal network of knowledge exchange in the early modern period that is widely recognised by historians of science, but all too rarely illustrated.

Whether churches should be demolished, rebuilt, restored or preserved is a contentious issue. Some hold that the needs of a present worshipping community should take precedence over antiquarian or aesthetic interest, others that we owe a debt to the ages. Arguments mirror those between developers and environmentalists. It is argued here that it is not abstract rights that matter, but a sense of history, and of the sacred. Church buildings and landscapes are to be maintained not as museum pieces but (...) as living elements of a humane piety. (shrink)

Abstract.Since the gene splicing debates of the 1980s, the public has been exposed to an ongoing sequence of genetic and reproductive technologies. Many issue areas have outcomes that lose track of people's inner values or engender opposing religious viewpoints defying final resolution. This essay relocates the discussion of what is an acceptable application from the individual to the societal level, examining technologies that stand to address large numbers of people and thus call for policy resolution, rather than individual fiat, in (...) their application. A major source of guidance is the “Genetic Frontiers” series of professional dialogues and conferences held by the National Conference for Community and Justice from 2002 to 2004. Genetic testing, human gene therapy, genetic engineering of plants and animals, and stem cell technology are examined. While differences in perspective on the beginning of life persist, a stepwise approach to the examination of genetic testing reveals areas of general agreement. Stewardship of life, human co‐creativity with the divine, and social justice help define the bounds of application of genetic engineering and therapy; compassionate care plays a major role in establishing stem cell policy. Active, sustained dialogue is a useful resource for enabling sharing of religious values and crystallization of policies. (shrink)

During times of economic uncertainty, such as the current period, all costs of agricultural production become important and worthy of close scrutiny if the threat of farm foreclosures is to be minimized. This concern particularly applies to the cost of plant nutrients, which, under conventional approaches, typically represents 24%–30% (or more) of the total variable costs of production [Lu et al. (2000) Food Reviews International 16(2): 121–157; Bullen and Brown (2001) Economic Evaluation of UNR Cotton, NC State University, Raleigh, North (...) Carolina]. The purpose of this paper is to examine, via a review of the literature, the economics and profitability of various plant nutrient management strategies–both conventional and alternative ones–in an attempt to identify those strategies that can lead to financial resource optimization and, ultimately, maximum profits for farm enterprises. The results of this analysis are as follows: In a meta-analysis of 120 studies, conventional nutrient management systems, using commercial fertilizers, showed higher profit for most grain crops (with the exception of corn and sorghum), than organic nutrient management systems. Both cover crop and animal manure-based systems show considerable promise as alternative nutrient management strategies for increasing farm profitability. A cover crop system produced the highest average corn yield and gross margin per hectare with the smallest coefficient of variation compared to no-tillage conventional, manure-based, or crownvetch systems. Manure-based systems that do not require purchase or transport of the manure (as in combined animal and crop production systems) can be considerably more profitable than conventional systems. Both manure-based and cover crop systems that do not include the use of commercial fertilizers (i.e., organic systems), hold particular promise due to the output price premiums typically garnered by the organic crops grown under such conditions.

The standard account of method (SAM) describes business and management research as a choice between “two traditions”: “qualitative “phenomenological” interpretivism” and “quantitative ‘scientific’ positivism”; each the enemy of the other. Students assemble “advantages and disadvantages” of each, pledge their allegiance, or a preference for “mixed method” (wishing for a “truce” in the “paradigm war”). In our increasingly Fordist academies, these variants attract grade-weightings of typically 20%, defined by “marking schemes” which are also standardised. Fordism is the management strategy of standardisation, (...) deskilling, low unit-cost, simple assembly and central control. We argue that SAM “Fordises” the intellect and confounds our experience that inquiry entails the greatest customisation humanly possible. Moreover, unlike Ford’s River Rouge plant, SAM is plagued by faults: thousands of category mistakes caused by collapsing unrelated methodological dimensions into one simple-looking yet multiply mistaken dichotomy. Happily, natural language facilitates myriad methodological distinctions which untutored inquirers articulate with more facility, pluralism and precision than SAM. By providing better labelling for their easy instincts, naïve inquirers can recognise and revel in what they did not know. (shrink)

Following the 1980 US Supreme Court decision to allow a patent on a living organism, debate has continued on the moral issues involved in biotechnology patents of many kinds and remains a contentious issue for those opposed to the use of biotechnology in industry and agriculture. Attitudes to patenting in the life sciences, including those of the research scientists themselves, are analysed. The relevance of morality to patent law is discussed here in an international context with particular reference to the (...) law of the European Patent Convention administered by the European Patent Office (EPO). The EPO has been the principal forum for opposition to such patents and the few cases under dispute in the EPO are reviewed, including patents for the onco-mouse, human relaxin gene, and the PGS herbicidally resistant plant (gmo). Morality provisions in the European Parliament and Council Directive 98/44/EC are also summarised. (shrink)

This paper explores how to deliberate about food choices from a Stoic perspective informed by the value of environmental sustainability. This perspective is reconstructed from both ancient and contemporary sources of Stoic philosophy. An account of what the Stoic goal of “living in agreement with Nature” would amount to in dietary practice is presented. Given ecological facts about food production, an argument is made that Stoic virtue made manifest as wisdom, justice, courage, and temperance compel Stoic practitioners to select locally (...) sourced, low resource input, plant-based foods whenever circumstances allow.

Through an interdisciplinary approach, I attempt to construct a partial ethno-agronomy of the Seneca people in late pre-contact times and examine it for relevance to modern agriculture.Diohe'ko, the Three Sisters, had been cultivated for at least five hundred years prior to contact by the Seneca, an Iroquoian tribe inhabiting western New York State. The Three Sisters, corn, beans and squash (pumpkins, gourds), were planted together in hills in fields, cultivated and harvested by work parties of women.Changes of village sites and (...) patterns of village movement respond to the adoption of agriculture as well as other factors. Evaluating land use, crop yields and carrying capacity, I question the accuracy of Seneca population estimates.The Three Sisters was an important cultural complex. The Sisters are protagonists of a number of Seneca tales, myths, ceremonies and legends.As an agricultural strategy, Three Sisters embodies several efficiencies in growth patterns, nutrient, solar and water use, harvest and nutritional use. Microhabitat manipulation was practiced by the Seneca. The plants exhibit a high degree of cooperation, or commensality, in the association.Some preliminary judgments can be made about specific varieties of the Sisters in use among the Seneca prior to contact. Northern Flint Corn, Cutshort or Cornhill Beans, and Cucurbita pepo such as Crookneck Squashes are likely the eldest varieties in the area.Three Sisters agriculture demonstrates qualities of permanence and sustainability, especially as related to the Seneca cultural fabric. A conservative ethic, like Handsome Lake's teaching, it binds together people in culture and people and nurture in nature. Mary Jemison, who farmed both the colonial and Three Sisters ways, seems to have favored the latter's “leisurely” approach. (shrink)

In biosemiotics, some oppose the study of sign relations to empirical work on bio-mechanisms. Urging consilience between these views, we show the value of Alain Berthoz’s concept of simplexity. Its heuristic power is to present molecules, cells, organisms and communities as using tricks to self-fabricate by agglomerating ‘simplex’ bio-mechanisms. Their properties enable living systems to self-sustain, adapt and, at best, to thrive. But simplexity also empowers agents to engage with their surroundings in novel ways. Life thus not only generates know-how (...) but also social organisation. With languaging, people can act and inhibit: they can also simplexify. As a result, we can see a fruit as ripe, feel when things are awry or behave in ways likely to be judged to be apt. While all living beings make situated use of the historical and the local, humans also bind these with the use of both practices and artifacts. As a result, brains come to emulate what occurs in-between persons and their surroundings. In pursuing the basis for our powers, we focus on inhibition. This simplex trick enables a plant to use dormancy, a bird to learn, and a person to mesh languaging with other aspects of action/perception. Indeed, inhibition enriches human style phenomenology as impersonal resources are used to expand our epistemic horizons. Experience links a self-fabricating body, ancient bio-mechanisms, community-based concerns and epigenetically derived know-how. (shrink)

Urban and agricultural communities are interdependent but often differ on approaches for improving water quality impaired by nutrient runoff waterbodies worldwide. Current water quality governance involves an overlapping array of policy tools implemented by governments, civil society organizations, and corporate supply chains. The choice of regulatory and voluntary tools is likely to influence many dimensions of the relationship between urban and agricultural actors. These relationships then influence future conditions for collective decision-making since many actors participate for multiple years in water (...) quality improvement. In this policy analysis, we draw on our professional experiences and research, as well as academic and practitioner literatures, to investigate how different types of water quality interventions influence urban-agricultural relationships, specifically examining policy tools on a regulatory to voluntary spectrum. Interactions between farmers and other rural agricultural interests on one hand, and urban residents and their stormwater managers and wastewater treatment plants on the other, influence dynamics relevant for water quality improvement. We suggest that the selection of policy tools within complex governance contexts influence urban–agricultural relationships through financial exchange, political coalitions, knowledge exchange, interpersonal relationships, and shared sense of place. Policy tools that provide a means to build relationships and engage with people’s emotions and identities have potential to influence personal and community change and adaptive capacity, while processes such as lawsuits can catalyze structural change. Engaging these relationships is particularly critical given the need to move out of polarized positions to solve collective problems. (shrink)

"Biophilia" is the term coined by Edward O. Wilson to describe what he believes is humanity's innate affinity for the natural world. In his landmark book Biophilia, he examined how our tendency to focus on life and lifelike processes might be a biologically based need, integral to our development as individuals and as a species. That idea has caught the imagination of diverse thinkers. The Biophilia Hypothesis brings together the views of some of the most creative scientists of our time, (...) each attempting to amplify and refine the concept of biophilia. The variety of perspectives -- psychological, biological, cultural, symbolic, and aesthetic -- frame the theoretical issues by presenting empirical evidence that supports or refutes the hypothesis. Numerous examples illustrate the idea that biophilia and its converse, biophobia, have a genetic component: fear, and even full-blown phobias of snakes and spiders are quick to develop with very little negative reinforcement, while more threatening modern artifacts -- knives, guns, automobiles -- rarely elicit such a response people find trees that are climbable and have a broad, umbrella-like canopy more attractive than trees without these characteristics people would rather look at water, green vegetation, or flowers than built structures of glass and concrete The biophilia hypothesis, if substantiated, provides a powerful argument for the conservation of biological diversity. More important, it implies serious consequences for our well-being as society becomes further estranged from the natural world. Relentless environmental destruction could have a significant impact on our quality of life, not just materially but psychologically and even spiritually. (shrink)

An examination of verbal hallucinations and thought insertion as examples of "alienated self-consciousness.".

Transnational corporations have become actors with significant political power and authority which should entail responsibility and liability, specifically direct liability for complicity in human rights violations. Holding TNCs liable for human rights violations is complicated by the discontinuity between the fragmented legal/political structure of the TNC and its integrated strategic reality and the international state system which privileges sovereignty and non-intervention over the protection of individual rights. However, the post-Westphalian transition—the emergence of multiple authorities, increasing ambiguity of borders and jurisdiction (...) and blurring of the line between the public and private spheres—should facilitate imposing direct responsibility on transnational firms. Mechanisms for imposing direct responsibility on TNCs are considered including voluntary agreements and international law. However, I conclude that a hybrid public-private regime which relies on non-hierarchical compliance mechanisms is likely to be both more effective and consistent with the structure of the emerging transnational order.

This book is an important entry in a distinctive new series from Routledge: "The Great Philosophers." Breaking down obstacles to understanding the ideas of history's greatest thinkers, these brief, accessible, and affordable volumes offer essential introductions to the great philosophers of the Western tradition from Plato to Wittgenstein.In just 64 pages, each author, a specialist on his subject, places the philosopher and his (...) ideas into historical perspective. Each volume explains, in simple terms, the basic concepts, enriching the narrative through the effective use of biographical detail. And instead of attempting to explain the philosopher's entire intellectual history, which can be daunting, this series takes one central theme in each philosopher's work, using it to unfold the philosopher's thoughts.

Undergraduate students with no prior classroom instruction in mathematical logic will benefit from this evenhanded multipart text by one of the centuries greatest authorities on the subject. Part I offers an elementary but thorough overview of mathematical logic of first order. The treatment does not stop with a single method of formulating logic; students receive instruction in a variety of techniques, first learning model theory (truth tables), then Hilbert-type proof theory, and proof theory handled through derived rules. Part II supplements (...) the material covered in Part I and introduces some of the newer ideas and the more profound results of logical research in the twentieth century. Subsequent chapters introduce the study of formal number theory, with surveys of the famous incompleteness and undecidability results of Godel, Church, Turing, and others. The emphasis in the final chapter reverts to logic, with examinations of Godel's completeness theorem, Gentzen's theorem, Skolem's paradox and nonstandard models of arithmetic, and other theorems.

Every naturalist who has directed his attention to the subject of the geographical distribution of animals and plants, must have been interested in the singular facts which it presents. Many of these facts are quite different from what would have been anticipated, and have hitherto been considered as highly curious, but quite inexplicable. None of the explanations attempted from the time of Linnaeus are now considered at all satisfactory; none of them have given a cause sufficient to account for the (...) facts known at the time, or comprehensive enough to include all the new facts which have since been, and are daily being added. Of late years, however, a great light has been thrown upon the subject by geological investigations, which have shown that the present state of the earth and of the organisms now inhabiting it, is but the last stage of a long and uninterrupted series of changes which it has undergone, and consequently, that to endeavour to explain and account for its present condition without any reference to those changes (as has frequently been done) must lead to very imperfect and erroneous conclusions.

The Aesthetics of Organization accessibly draws key contributions delineating the emerging parameters of the field. It explains the significance of concepts devised by postmodern thinkers, through which emerge meaning and order in organizations. Methodological problems associated with investigations of the aesthetic are also highlighted so the reader can identify and understand the importance of recent ideas on vision, perspective (...) and periphery for learning in organizations. Through the contributions of leading international theorists, organizational aesthetics is defined in greater historical and theoretical depth, with a broad conceptual and practical range which academics will find invaluable.

This entry offers a critical overview of the contemporary literature on understanding, especially in epistemology and the philosophy of science.

Hume thought that if you believed in powers, you believed in necessary connections in nature. He was then able to argue that there were none such because anything could follow anything else. But Hume wrong-footed his opponents. A power does not necessitate its manifestations: rather, it disposes towards them in a way that is less than necessary but more than purely contingent. -/- In this paper a dispositional theory of causation is offered. Causes dispose towards their effects and often produce (...) them. But a set of causes, even though they may succeed in producing an effect, cannot necessitate it since the effect could have been counteracted by some additional power. This would require a separation of our concepts of causal production and causal necessitation. The most conspicuous cases of causation are those where powers accumulate and pass a requisite threshold for an effect to occur. -/- We develop a model for representing powers as constituent vectors within an n-dimensional quality space, where composition of causes appears as vector addition. Even our resultant vector, however, has to be understood as having dispositional force only. This model throws new light on causal modality and cases of prevention, causation by absence and probabilistic causation. (shrink)
