This article presents a holistic framework for understanding the scienceof plant breeding, as an alternative to the common objectivist andconstructivist approaches in studies of science. It applies thisapproach to understanding disagreements about how to deal with yieldstability. Two contrasting definitions of yield stability are described,and concomitant differences in the understanding and roles ofsustainability and of selection, test, and target environments areexplored. Critical questions about plant breeding theory and practiceare posed, and answers from the viewpoint of the two contrastingdefinitions of yield (...) stability are analyzed, based on key publicationsin the field. Differences in answers to these questions appear to resultboth from the contingencies of plant breeders' experiences withparticular crop varieties and growing environments, and from differencesin social and institutional settings – plant breeding science isboth objective truth and social construction. The goal of using aholistic framework is to encourage discussion among plant breeders,farmers, social scientists, and others, of the bases for disagreementswithin plant breeding, in order to facilitate plant breeding'scontribution to a more environmentally, economically, and sociallysustainable agriculture.

Philosophers and scientists propose the idea that plants are cognitive, which has been met with criticisms. These criticisms focus on the fact that plants do not possess the properties traditionally associated with cognition. By contrast, several proponents introduce novel ways to conceptualize cognition. How should we make sense of this debate? In this paper, I argue that the plant cognition debate is not about whether plants meet a set of well-delineated and agreed-upon criteria according to which they count as cognitive. (...) Rather, many proponents are hypothesizing about cognition. They construe COGNITION not as an expression of what cognition is, but rather as a conjecture about what cognition might be. These conjectures orient research that can uncover novel similarities amongst the phenomena to which these concepts extend. In defending this view, I argue that investigating plant cognition is valuable, even if the results of these investigations lead us to reject the claim that plants are cognitive. (shrink)

For much of the twentieth century, plant physiologists considered themselves in an ideal position to study and explain the functions and processes of plants. Much of that authority stemmed from plant physiologists’ long-standing commitment to experimental control and the integration of the physical sciences into biological practice. This article places plant physiology back in the center of the story of the recent life sciences. It shows the development of parallel experimental research programs into environmental as well as genetic effects on (...) growth and development in plant physiology and genetics, and notes that the pursuit of an experimental environment was celebrated as much as a molecular vision of life throughout most of the twentieth century by much of the plant science community. Thus, this article concludes that the history of the recent life sciences needs new complementary narratives of plant physiology with genetics, new concepts with technological tools, and plant-sized scales with the molecular. The history of the ‘Age of Biology,’ as the plant scientists saw it, helps confront the issue first posed by Evelyn Fox Keller, namely that the history of genetics has overshadowed a larger history of experimental life science. My answer here is through a larger narrative of the rise of the complementary experimental sciences of genes and environments in the life sciences. (shrink)

Our question “How many chickens does it take to make an egg?” was inspired by the successful replacement of egg-based mayonnaise with plant-based mayonnaise in general dining at the University of California, Santa Barbara, in order to increase animal welfare. Our indicator of improved animal welfare due to decreased egg consumption was the reduction in number of chickens in the stressful and unhealthy conditions of the US egg industry. To measure this we calculated the ratio of chickens to eggs and (...) found it takes 6.3 chickens to make 1000 eggs. This equals 158 eggs per chicken, less than half the amount of eggs per laying hen because of mortality from hatching to entering the laying flock, including the disposal of male chicks. In addition, greenhouse gas emissions, irrigation water, reactive nitrogen, and land use would be reduced 43–98% from that of eggs. While the impact of plant-based mayonnaise was relatively small, we also estimated the substitution of eggs with tofu, which had a much greater impact: substituting 50% of eggs with tofu in first-year student breakfasts on all UC campuses would reduce the number of chickens in the egg industry by 9245. If this substitution was made by the US population, the welfare and environmental benefits would be 29 thousand times greater. Reducing egg consumption would greatly improve chicken welfare even if welfare certified eggs are replaced, since the requirements of the most commonly used chicken welfare certification programs do relatively little to reduce chicken suffering.

The Jewish exegete and philosopher Philo of Alexandria has long been famous for his complex and spiritually rich allegorical treatises on the Greek Bible. The present volume presents first translation and commentary in English on his treatise De plantatione (On planting), following on the volume devoted to On cultivation published previously by the same two authors. Philo gives a virtuoso performance as allegorist, interpreting Noah's planting of a vineyard in Genesis 9.20 first in theological and cosmological terms, then moving to (...) the spiritual quest of both of advanced souls and those beginning their journey. The translation renders Philo's baroque Greek into readable modern English. The commentary pays particular attention to the treatise's structure, its biblical basis and its exegetical and philosophical contents. (shrink)

This article examines the way in which public controversies affect regulatory science. It describes the controversy that unfolded in Europe around the use of the ninety-day rat-feeding tests for the risk assessment of genetically modified plants. This type of test had been criticized for almost two decades by toxicologists, nongovernmental organizations, and industry alike for its inability to capture the specific health effects of GM plants. But GM risk assessment experts showed great reluctance to move toward a more systematic use (...) of other tests, such as chronic two-year studies or toxicogenomic techniques, and made sure that official guidance continues to recommend the use of the ninety-day rat-feeding study. The article shows that these tactics of standardization are a defining feature of regulatory science, and a resource for toxicity experts to defend their authority and credibility against competing expertises that arise during controversies.

Most land plants associate with mycorrhizal fungi that can connect roots of neighboring plants in common mycelial networks (CMNs). Recent evidence shows that CMNs transfer warning signals of pathogen and aphid attack between plants. However, we do not know how defence‐related signaling via CMNs operates or how ubiquitous it is. Nor do we know what the ecological relevance and fitness consequences are, particularly from the perspective of the mycorrhizal fungus. Here, we focus on the potential fitness benefits for mycorrhizal fungi (...) and outline hypothetical scenarios in which signal transfer via CMNs is modulated in order to acquire the most benefit for the fungus (i.e. acquisition of carbon) for minimal cost. We speculate that the signal may be quantitative and may elicit plant defence responses on different levels depending on the distance the signal is transferred. Finally, we discuss the possibility of practical applications of this phenomenon for crop protection. (shrink)

The conservation of rice plant genetic diversity is particularly important for resource-poor farmers in economically marginal areas of the Philippines. This paper discusses the state of rice plant genetic diversity in the Philippines and the reasons behind the decrease in diversity witnessed over the last 30 years. A case study describes the in situ management of rice plant genetic diversity by resource-poor farmers from the Philippine island of Bohol, throughout the traditional, green revolution, and post-green revolution periods. This analysis demonstrates (...) that farmers tend to favor genetically heterogeneous varieties that adapt to varied environments. The case study also reviews an NGO-sponsored agricultural biodiversity project that demonstrates that rice plant genetic diversity can be increased by empowering farmers – providing them with access to varieties, knowledge of varietal trials, varietal selection, and varietal breeding, as well as increasing the linkages they have with other farmers and institutions.

The role of scientific theories in classifying plants and animals is traced from Hennig's phylogenetics and the evolutionary taxonomy of Simpson and Mayr, through numerical phenetics, to present-day cladistics. Hennig limited biological classification to sister groups so that this one relation can be expressed unambiguously in classifications. Simpson and Mayr were willing to sacrifice precision in representation in order to include additional features of evolution in the construction of classifications. In order to make classifications more objective, precise and quantitative, numerical (...) pheneticists limited themselves to representing degrees of phenetic similarity. Finally, present-day cladists can be separated into phylogenetic cladists, who retain much of Hennig's theory of classification, and pattern cladists, who have stripped Hennig's system down to its bare essentials.

The chromodomain is a highly conserved sequence motif that has been identified in a variety of animal and plant species. In mammals, chromodomain proteins appear to be either structural components of large macromolecular chromatin complexes or proteins involved in remodelling chromatin structure. Recent work has suggested that apart from a role in regulating gene activity, chromodomain proteins may also play roles in genome organisation. This article reviews progress made in characterising mammalian chromodomain proteins and emphasises their emerging role in the (...) regulation of gene expression and genome organisation.

Looking back we often take the Second Vatican Council as the point where change began.

Plant cell culture systems have become an attractive and sustainable approach to produce high‐value and commercially significant metabolites under controlled conditions. Strategies involving elicitor supplementation into plant cell culture media are employed to mimic natural conditions for increasing the metabolite yield. Studies on nanoparticles (NPs) that have investigated elicitation of specialized metabolism have shown the potential of NPs to be a substitute for biotic elicitors such as phytohormones and microbial extracts. Customizable physicochemical characteristics allow the design of monodispersed‐, stimulus‐responsive‐, and (...) hormone‐carrying‐NPs of precise geometries to enhance their elicitation capabilities based on target metabolite/plant cell culture type. We contextualize advances in NP‐mediated elicitation, especially stimulation of specialized metabolic pathways, the underlying mechanisms, impacts on gene regulation, and NP‐associated cytotoxicity. The novelty of the concept lies in unleashing the potential of designer NPs to enhance yield, harness metabolites, and transform nanoelicitation from exploratory investigations to a commercially viable strategy.

William James said that sometimes detailed philosophical argument is irrelevant. Once a current of thought is really under way, trying to oppose it with argument is like planting a stick in a river to try to alter its course: “round your obstacle flows the water and ‘gets there just the same’”. He thought pragmatism was such a river. There is a contemporary river that sometimes calls itself pragmatism, although other titles are probably better. At any rate it is the denial (...) of differences, the celebration of the seamless web of language, the soothing away of distinctions, whether of primary versus secondary, fact versus value, description versus expression, or of any other significant kind. What is left is a smooth, undifferentiated view of language, sometimes a nuanced kind of anthropomorphism or “internal” realism, sometimes the view that no view is possible: minimalism, deflationism, quietism. Wittgenstein is often admired as a high priest of the movement. Planting a stick in this water is probably futile, but having done it before I shall do it again, and—who knows?—enough sticks may make a dam, and the waters of error may subside.

Monogenesis of language is widely accepted, but the conventional argument seems to be mistaken; a simple probabilistic model shows that polygenesis is likely. Other prehistoric inventions are discussed, as are problems in tracing linguistic lineages. Language is a system of representations; within such a system, words can evoke complex and systematic responses. Along with its social functions, language is important to humans as a mental instrument. Indeed, the invention of language,that is the accumulation of symbols to represent emotions, objects, and (...) acts may be the most important event in human evolution, because so many developments follow from it. For example, Edward Sapir speculated that some embryonic form of language must have been available to early man to help him fashion tools from stone (Sapir,1921). Sophisticated biface stone tools date to early Homo erectus some 1.5 million years ago, suggesting a similar age for language. This paper considers whether the invention of language occurred at only one pre-historic site or at several sites. In other words, did language emerge by monogenesis or polygenesis? Early thinkers believed in monogenesis, against a background of divine creation. Perhaps the best known account is the biblical story of Adam giving names to plants and animals in the Garden of Eden. Similar legends are found among many peoples. Modern linguists too assume monogenesis, but on probabilistic grounds (see, for instance, Southworth and Daswani, 1974, p.314). The argument seems to be that the invention of language is an extremely unlikely event, because symbolization involves abstraction and requires synchronized insight by several individuals; therefore, the probability of occurrence at more than one site must be vanishingly small. We have found no explicit quantitative treatment of this question in the literature, but the underlying logic has to be the multiplication of probabilities. If p is small at one site,then p.p for two sites is smaller still, and so on. This reasoning is false, as we show here. The fallacy lies in the focus on two particular sites rather than consideration of all pairs of sites. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Good Work:An Engaged Buddhist Response to the Dilemmas of ConsumerismDavid Landis BarnhillConsumerism is such an ingrained part of our culture, it is paradoxically difficult to avoid and easy to ignore. Sometimes it seems like the water we modern fish swim in.But the Buddhist call to awareness of our state of mind and the nature of reality leads us to reflect on it, to encounter it as directly as possible. (...) When we do, it is all too clear that consumerism goes directly against virtually everything Buddhism stands for. In thinking about a Buddhist response to it, what first comes to mind is the rich monastic tradition, with its trenchant analysis of the pervasiveness of desires, the ideal of life lifted free of craving, and the inviting simplicity of the communal life. But as an engaged Buddhist, I almost immediately feel that, compelling as it is, this monastic tradition is insufficient, particularly at a time when consumerism has become so devastating on a global scale. While the monastic tradition offers a model of a nonconsumer lifestyle, it does little to affect the industrialized world's accelerating exhaustion of natural resources. I sometimes put this point in mythical Buddhist imagery by saying that we live in a culture of hungry ghosts.1 But that would be optimistic. While hungry ghosts have a bloated stomach of insatiable cravings, their throats are as thin as pins. Modern culture has a gargantuan mouth and throat, and yet we still act as if our bellies are empty.So what can we as Buddhists do about such a destructive culture? Engaged Buddhism is a way of confronting social, political, and psychological poisons that threaten our world, and it offers an effective counter to consumer culture in at least three main ways. There is the extension of the Buddhist analysis of reality beyond the psychological and the metaphysical to the social, structural dimension of life of economic systems and political institutions. In the social context, the Buddhist truth of the mutual co-arising of phenomena takes on a more immense scope than the mere conditioning of consciousness, and a more concrete—and thus soiled—quality than Huayan Buddhism's mesmerizing metaphysics of Indra's net. The interpenetration of life (pratītya-samutpāda) includes billboards and boardrooms, peasants uprooted from their land as coffee is planted in their place. I live not just in interrelationship with the postglacial hills of Wisconsin but also with the mountains of toxins spewed [End Page 55] into the air to give us cheap, but very costly, energy. As Stephen Batchelor has said, "the contemporary social engagement of Dharma practice is rooted in awareness of how self-centered confusion and craving can no longer be adequately understood only as psychological drives that manifest themselves in subjective states of anguish. We find these drives embodied in the very economic, military, and political structures that influence the lives of the majority of the people on Earth."2 Engaged Buddhism gives us an incisive way to comprehend and critique our situation, and we stand on more solid ground as we view the vast and painful interconnections.Second, engaged Buddhism also can give us a vision of a social and political alternative, one that is based not on the three poisons of greed, hatred, and delusion but on generosity, compassion, and wisdom. But in doing so Buddhism must go beyond the limits of its own tradition and draw on the insights of contemporary social and environmental philosophies, from anarchism to bioregionalism. A creative merging of Buddhism and such ecosocial thought can help us work toward a modern life of communalism rather than consumerism, of contentment rather than self-perpetuating desire.3Third, engaged Buddhism gives us a basis for directly responding to a world of craving and suffering. Activism against the rising tide of consumerism—and against the social, political, and military structures and the deafening ideologies that support it—can emerge from a meditational steadiness. Contemplative activism avoids rage, burnout, and psychic numbness and allows us to meet greed and hatred with peace in a spirituality of resistance. Such a religiously based activism, however, needs to join hands4 with social philosophy and... (shrink)

These starkly beautiful photographs document the daily life and labor of blue-collar workers in modern America. From a foundry in which the very fires of hell seem to blast to an air-conditioned computer control room in which the workers appear casual and comfortable, David Parker's lens captures what Peter Rachleff calls "a performance, a ritual, an exercise centuries ol""-men and women at work on factory floors. These photographs, taken in twenty plants in all parts of Minnesota, explore the common (...) bonds of industrial labor. Whether it's the Ford plant in St. Paul, the Potlatch paper mill in Cloquet, or the Toro engine manufacturer in Windom, Parker seeks to honor "the collective genius of the American worker." Excerpts from interviews with the workers reveal their opinions on such diverse topics as health care and child care, union activity, immigrant labor, and the effects of globalization. Their words and these photographs document industrial laborers and the factories in which they work, revealing how workers interact with each other and their environment and how the culture of labor is reflected in the jobs women and men do. An appendix provides a history and description of each workplace, detailing the magnitude of production and the constant ingenuity required to manufacture even the most common products. This book is a tribute to the women and men who process the foods we eat, manufacture the cars we drive, and produce the goods that make our lives comfortable. (shrink)

In the final chapter of Warrant and Proper Function, Alvin Planting a presents an “evolutionary argument against naturalism” (where naturalism is the claim that there are no supernatural beings). According to this argument, the conjunction of naturalism and evolution cannot be rationally believed by anyone who understands its epistemic implications. In this paper, I argue that if Plantinga’s evolutionary argument is sound, it follows that (what I call) perceptive naturalists have no propositional knowledge. Since it is plausible that perceptive naturalists (...) do have some propositional knowledge, I infer that the evolutionary argument (EA) is unsound. However, I conclude the paper with the suggestion that even if EA is unsound, it may still provide important insights about the epistemic shortcomings of naturalism. (shrink)

The aim of this paper is to show how the incorporation of metaphoric and poetic ways of thinking into the evaluation of a leadership development programme both captured the imagination of the employees and benefited the core business of a manufacturing production plant. Qualitative data evaluating the effectiveness of a substantial leadership programme were presented back to all members of a manufacturing plant (executive and non-executive) in the form of composite narratives over an eighteen-month period. Recommendations were derived from the (...) text of the narrative and were progressively implemented. Such was the positive response to the written narratives that senior management asked the researchers to present the narratives in the form of a ‘live’ performance. Evaluation through qualitative methodology lends itself to an imaginative interpretation and presentation. Although qualitative and quantitative data tend to be regarded as complementary in applied research, it was management’s decision to employ only a qualitative process in this instance. The decision was fortuitous, given that the leadership development programme was initially judged to be a failure, as it triggered a subsequent imaginative engagement that turned a failure into a success.

This article attempts to provide an overview and discussion of Plutarch’s views in his Moralia about emotions and their relation to moral virtue and reason. By tracking different clusters of imagery – artisanal, zoological and botanic – that Plutarch uses in his essays to articulate the relationship between emotions and reason, it explores three philosophical perspectives on emotions: emotions of a virtuous person are likened to a well-shaped piece of material; to animals that need to be guided or reined in (...) by their master; and to wholesome plants in a garden. Each of these imageries is used to support a different account of moral virtue: virtue as the emotional disposition to feel moderately; virtue as the obedience of emotions to the commands of reason; and virtue as the absence of bad emotions and flourishing of the good ones. This analysis enables us to weigh the influences of major philosophers on Plutarch’s account, and to elucidate his commitment on both metriopatheia and apatheia. (shrink)

The concept of culture is best understood from a genetic and functional point of view. To cultivate an object is to develop the potentialities of its nature with a view to a definite end or result. For example, agriculture is the process whereby the potentialities of the earth and of seeds are cultivated with a view to growing edible plants. Similarly, one may speak of pearl culture or bee culture to indicate the process of cultivation or production of pearls or (...) bees through the agency of man. By transference, the term has historically been applied to man himself and refers to the process of self-cultivation of man by man. Human culture, or anthropo-culture as it may be called, originally comprised the various ways in which man has tended his nature so as to make it grow or develop in a specific way. In classical Western civilization, as man differentiated between his body and his soul, he came to attach greater importance to the cultivation of his soul and culture became identified with the culture of the soul. Genetically, human culture refers to the education, or cultivation, of the whole man considered as an organism and not only to the mental or spiritual aspects of his nature. Plato’s concept of paideia, which comprised the education of the body through gymnastics and that of the soul through the liberal arts, reflects this holistic approach to the human cultural process. In time, culture came to mean the state of being educated as distinct from the process of education and then, still later, came to refer to the whole intelligible world revealed by education, to wisdom as a product of a liberal education.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 8.2 (2003) 31-41 [Access article in PDF] Threescore and TenFire, Place, and Loss in the West David Strohmaier The only conclusion I have ever reached about trees is that I love all trees, but I am in love with pines. —Aldo Leopold, A Sand County Almanac 1He died protecting his pines. It was spring, 1948, and Aldo Leopold was spending time with his family (...) at their beloved cabin they called "the Shack." Over the years, he had planted close to 30,000 trees and shrubs on the property, trying to resuscitate a tired Wisconsin sand farm into some semblance of ecological health. 2 Leopold was keenly aware of fire's natural role in ecosystems, but sometimes there's more to fire and living with fire than energy flow, nutrient flush, and plant physiology. 3During the Leopolds' stay at the Shack, a neighbor's trash fire, fanned by a west wind, escaped its bounds and threatened to overtake the pines. Alone, along one flank of the fire, Aldo suffered a heart attack and was later found dead, lying on his back in the smoldering grass. 4 For the love of pines.In A Sand County Almanac (accepted for publication just one week before his death), Leopold explores several possible reasons for his bias [End Page 31] towards pines: maybe it's because he planted the pines, or pines are rare where he lives, or pines have a longer life expectancy than other trees, or pines are evergreens, or because his neighbors don't have many pines on their land, or pines are worth more to the lumberman than other species, or pines engender more plant diversity than other species. In the end, he concludes that our plant biases reflect not only vocations but avocations, with a delicate allocation of priority as between industry and indolence. The farmer who would rather hunt grouse than milk cows will not dislike hawthorn, no matter if it does invade his pasture. The coon-hunter will not dislike basswood, and I know of quail hunters who bear no grudge against ragweed, despite their annual bout with hayfever. Our biases are indeed a sensitive index to our affections, our tastes, our loyalties, our generosities, and our manner of wasting weekends. 5Leopold's last act in life—fighting a fire endangering something he valued—testifies to the tension between Leopold's concept of thinking like a mountain and our reality of living in the present, between mountain time and human time. It's doubtful that the landscape around the Shack would have suffered permanent damage even if the fire overran his pines. Some trees would have burned and died, but, eventually, the land would revegetate and more pines could be planted. But for humans who, according to the psalmist, live but "[t]hreescore and ten, or even by reason of strength fourscore," 6 we may never see our pines, or any other part of the landscape, fully healed, assuming it even can be. One tree, or grove of trees, is not necessarily interchangeable with another. Places can be lost and never replaced. This is one reason why philosopher Robert Elliot is so skeptical of ecological restoration. Like a work of art, simply replacing it with the most exacting replica will never fully replace the original, for part of an object's value derives from its history: who painted or sculpted it, when it was crafted, the reason behind its contours and colors. 7 Not only are exact replicas in nature hard to come by (even though our science and technology of restoration is improving), but some values can never be restored.Some things are worth protecting from fire simply because they're important to us—even a part of us—and not necessarily because they're resources on their way to becoming beef, venison, or two-by-fours. What's critical, though, as we struggle to live in a land that burns, is getting clear about how we want that land to look and why. I fear that we... (shrink)

This paper is concerned with the application of science to a practical activity. The story begins in the late eighteenth century, a period of agricultural innovation, with various authors urging that definite chemical knowledge should replace rule of thumb in the application of fertilisers. In the work of Archibald Cochrane, ninth Earl of Dundonald, we find this exhortation beginning to give way to descriptions of actual chemical experiments, and interpretations of equilibria in the soil. But it is only with Davy's (...) Agricultural chemistry of 1813 that we get clear descriptions of soil analyses that could be undertaken by a farmer, accompanied with a certain amount of biochemical information on the growth of plants. Davy's recommendations were essentially conservative; he provided support for the best practices already being recommended by innovators. His book is interesting too, for the light it casts upon his more theoretical writings. (shrink)

In most traditions, the law is founded upon some extralegal view of morality. There are only a handful of cases prior to the 1970s that involved patenting nonhuman organisms. John Moore made several claims, but the one of most interest to us here was a claim for conversion, which means the unlawful use of another person's property for the enrichment of the person using the thing unlawfully. The cell line produced from Moore's spleen cells was eventually patented by the defendants. (...) The potential market for products relating to that patent was estimated to be roughly $3 billion US dollars. The move from patenting hybridized plants, to genetically altered microorganisms, to human tissues and genes reflected the epitome of the fabled slippery slope. There is clearly a gap between our intuitions about the relations between our individual genomes, our identities, perceptions of privacy and personal autonomy, and the law. (shrink)

Philosophers, Henri Bergson once observed, "seem to philosophize as if they were sealed in the privacy of their study and did not live on a planet surrounded by the vast organic world of animals, plants, insects, and protozoa." Providing a solid overview of ecological philosophy and original insights into this developing field, Minding Nature focuses on some of the most influential thinkers who, in fact, have emphasized our natural relations to the earth, our social creations, and each other. Combining philosophy, (...) ecology, and political theory, chapters thoroughly examine, critique, and build upon the ideas of such luminaries as Thomas Hobbes, Martin Heidegger, Ernst Bloch, Hannah Arendt, Herbert Marcuse, Barry Commoner, Rachel Carson, and Jurgen Habermas, among others. Each thinker considered has contributed significantly to both contemporary discussion and historical understanding of political, epistemological, or social aspects related to nature and, with several exceptions, stimulated constructive dialogue within progressive, democratic, and radical left circles. By challenging the notion that conservation is inherently politically conservative or that our oikos (home) must be rendered uniformly economic where ecology is concerned, they enable us to rethink the possibility of creating a more democratic and ecological society.

It has been suggested that we turn to solar geoengineering to counter global warming, which would consequently transform the relationship of terrestrial plant-life to the sun. This is an article not about geoengineering as such, but instead what is called photosynethics, or, thinking about our moral relationship to the light – in particular, as it is mediated by plants. Working from within but then extending the idea of responsibility found in the work of Emmanuel Levinas, it is argued here that, (...) since the plant cultivates the conditions of life on earth by photosynthesis, its relationship to the sun is then a relation of giving to others that is properly moral. The plant’s existence is an exposure so out of kilter with human ways of understanding existence that it interrupts our own and brings us into a relation of responsibility. It is concluded that rather than redirecting the sun’s radiation, we should turn to plants to reconsider how we live with the light on a heating planet. This first means separating moral responsibility from human vision so that we might encounter light on its own terms, and not simply as an element of rationality or sentiment or discipline. (shrink)

Since the late 1960's, a mix of government policies has prevented the loss of farmland in Sweden, “either to forest or asphalt”; these policies have also ensured the maintenance of soil fertility and groundwater resources. However, in Sweden as in several other European nations, a chronic and growing “grain glut” in recent years has undermined the economic logic of import protection and farm price supports—the principle means of promoting a sustainable agriculture. Mainstream economists, imbued with urban-biased and production-centered values, have (...) long criticized these costly mechanisms of public support as cost-ineffective and socially unjustified. They and many prominent politicians tend to minimize the non-production benefits of maintaining an open “working landscape” and rural communities dependent upon agriculture. Historically, Sweden's major farm organizations and its agrarian political party have resisted this economistic view with considerable success. Therefore it was a shock to many observers when, in 1986, leaders of the Swedish Federation of Farmers itself proposed planting trees on crop land as one element of a solution to overproduction.This essay traces the evolution of Swedish farm debates and policies since World War II, leading to the present critical juncture. It explores the incipient alliance between farmers and conservationists to protect farmland (as well as family farms and farm communities) and assesses the prospects for maintaining land in production through diversification into biomass energy crops and high protein fodder crops (the former option takes on new significance in the wake of the Chernobil disaster and pressure for early de-commissioning of Sweden's nuclear power plants; the latter would reduce Swedish dependence on imported soybeans). Finally, there is speculation on the relevance of Sweden's experience for American farmland policy. (shrink)

The argument as far as 205 is simply and clearly laid out by Munro, but later editors have rejected his explanation, and proposed more involved analyses. The first purpose of this paper is to support the simple interpretation and refute later complications. The only serious difficulty lies in the mention of plants in line 189. Without this line the argument would run as follows. ‘Nothing can move upwards of its own accord’. ‘Don&t be misled by the atoms of flames, for (...) they spring into being and take their increase in an upward direction, although all weights, left to themselves, move downwards’. ‘Nor must we believe that when fire leaps up to the roofs of houses …, it does so of its own accord’. Now the two analogicalarguments: ‘For blood spurts up into the air and timbers leap out of the water, yet everybody agrees that their weights left to themselves move downwards’. Now the conclusion repeating the original proposition: ‘This is how it must be that flames too rise, forced out upwards through the air although their weights, left to themselves, move downwards’.

In lieu of an abstract, here is a brief excerpt of the content:Artforum, Andy Warhol, and the Art of Living:What Art Educators Can Learn from the Recent History of American Art WritingDavid Carrier (bio)When around 1980 I began writing art criticism, Artforum was much concerned with historical analysis.1 When presenting the work of younger painters and sculptors, it seemed natural to explain artists' accomplishments by identifying precedents for their work. Much of my criticism published in the 1980s presented post-formalist accounts (...) of abstract painting. Seeking precedents for the painting I admired, I looked to the history of art. But such pleas for the value of tradition were doomed. Commentators preaching the values of tradition lost out to the writers emphasizing a break with the past. Much of interest for art education can be learned by studying the history of this very influential, small circulation journal.Only in retrospect did the urgency of this felt need for a break with the past become apparent. The history of responses to Abstract Expressionism suggested a different way of thinking about moments of change. HaroldRosenberg's conception of "action painting" implied that Pollock broke dramatically with the past. Clement Greenberg, by contrast, in a famous phrase said: "I do not think it exaggerated to say that Pollock's 1946-1950 manner really took up Analytic Cubism from the point at which Picasso and Braquehad left it...in their collages of 1912 and 1913."2 Greenberg's counter-intuitive analysis, asking us to see very different looking paintings as essentially similar, had prevailed. So it was not unreasonable to expect that after Greenberg, concern with tradition would remain important. But that was not what happened.Demand for a break with the past often carries political overtones. Historians debate whether the French Revolution broke with the past, or merely developed trends of the old regime. The idea of a complete break with tradition can seem attractive, but of course such dramatic ways of thinking underestimate real continuities. Struggle among post-Greenbergian artwriters to define a new critical paradigm mimics conflicts among artists to define the [End Page 1] leading post-Abstract Expressionist tradition. Once a critical paradigm has been established, debate may proceed peacefully. But when defining a period style is at issue, the stakes are high, and so conflicts are ferocious. Of course, struggle is always accompanied also by co-operation, but failing to grasp the real role of conflict leads to all-too-pious visions of what is possible.Greenberg developedthe most influential critical approach, and so when his way of thinking was rejected, a radically different approach was of most interest. Here we are dealing with what Harold Bloom famously called the anxiety of influence. Just as the most interesting painting after Abstract Expressionism deconstructed that tradition, so in criticism no ways of thinking too similar to Greenberg's stood a chance of being important. I think it interesting to reconstruct the process rationally in which an individual obtains such power. A totem, Freud explains, is "an animal (whether edible and harmless or dangerous and feared) and more rarely a plant or a natural phenomenon (such as rain or water), which stands in a peculiar relation to the whole clan."3 The communion bread and wine are just bread and wine, but for the believer they become Christ's body and blood. Rationally speaking, a representational painting is just pigment on canvas; and a minimalist sculpture, just shaped metal. But in what Arthur Danto calls the "transfiguration of the commonplace," "a work of art...has qualities to attend to which its untransfigured counterpart lacks...We are dealing with an altogether different order of things."4 Greenberg became a totem. He was not just an important writer whose arguments entitled him to reasonable respect. The mere mention of his name invoked irrational fears.Greenberg was obsessed with tradition. Abstract Expressionism was rooted in early modernism, so that the era from Manet through Pollock defined a period style. Greenberg's historiography may seem inescapable. How can a young painter be understood except by seeking precedents for her achievement? Cannot the now famous artists who emerged in the 1980s be understood in these terms? Barbara Kruger comes out of John Heartfield and dada... (shrink)

Preserved human remains from ancient Egypt provide an unparalleled opportunity for studies in the history of disease and medical practices. Egyptian medical papyri describe physiological concepts, disease diagnoses and prescribed treatments which include both ‘irrational’, and ‘rational’ procedures. Many previous studies of Egyptian medicine have concluded that ‘irrational’ methods predominated, but this perception is increasingly challenged by results from scientific studies of ancient human remains, and plant materials. This paper demonstrates the significant contribution being made by multidisciplinary studies to our (...) understanding of disease occurrence and medical treatments in ancient Egypt, and considers the feasibility of developing epidemiological comparisons of ancient and modern data sets that will provide acceptable historical contexts for contemporary disease studies.

Imagine that you are the last human being. When you are gone, the only life remaining will be plants, microbes, invertebrates. For some reason, this thought runs through your head: Before I die, it sure would be fun to blow up the last remaining redwood. What, if anything, would be wrong with destroying that redwood? Destroying it won’t hurt any person, or even any sentient creature. It won’t hurt anything. So, what’s the problem? This chapter reflects on the possibility of (...) finding intrinsic value, objective value, incommensurate value, moral standing, and grounds for self-respect in the nonhuman natural world. (shrink)

Growing up, I was a mathematics and science geek. I read everything I could in these areas. Every now and then, something would point in a philosophical direction. Perhaps my most important influence was reading Hofstadter’s Gödel, Escher, Bach as a teenager. I read it initially for the mathematical parts, but it planted a seed for thinking about the mind. Later, Hofstadter and Dennett’s The Mind’s I got me thinking more about the mind–body problem in particular.

Contrary to mammalian DNA, which is thought to contain only 5-methylcytosine (m5C), bacterial DNA contains two additional methylated bases, namely N6-methyladenine (m6A), and N4-methylcytosine (m4C). However, if the main function of m5C and m4C in bacteria is protection against restriction enzymes, the roles of m6A are multiple and include, for example, the regulation of virulence and the control of many bacterial DNA functions such as the replication, repair, expression and transposition of DNA. Interestingly, even if adenine methylation is usually considered (...) a bacterial DNA feature, the presence of m6A has been found in protist and plant DNAs. Furthermore, indirect evidence suggests the presence of m6A in mammal DNA, raising the possibility that this base has remained undetected due to the low sensitivity of the analytical methods used. This highlights the importance of considering m6A as the sixth element of DNA. BioEssays 28: 309–315, 2006. © 2006 Wiley Periodicals, Inc. (shrink)

Drug effects on consciousness are powerful probes of how physical processes in the body are connected to conscious experience. Drugs that alter consciousness – producing arousal, sedation, sleep, anesthesia, analgesia, euphoria, amnesia, hallucinations, or psychedelic‐like intensification of perceptions, thoughts, and feelings – have been identified as interacting in various ways with cellular and molecular processes within the nervous system. While the focus has thus far been on synaptic connections between neurons, there is likely to be much more going on in (...) the interaction of drugs with living systems that has not yet been identified. Psychedelic drugs, plants, and fungi are associated with perhaps the most interesting and profound of the drug‐induced alterations of consciousness. Contemporary investigations of psychedelics include renewed interest in the transformational therapeutic potential of these substances, and may also lead to new insights into the nature of consciousness.
