Within this paper, I critique the history of the modification of the broiler chicken through selective breeding and possible future genetic modification. I utilize Margaret Atwood’s fictitious depiction of genetically engineered chickens, from her novel Oryx and Crake , in order to forward the argument that modifications that eliminate animal telos either move beyond the range of current ethical frameworks or can be ethically defended by them. I then utilize the work of feminist epistemologists to argue that understanding what (...) it means to be a chicken shapes our conceptions of what modifications are or are not acceptable. Taking into account justifications stemming from practical knowledge when making ontological claims can help to shift our understanding of what animal modifications can or cannot be justified. The paper ends by addressing three possible problems brought about by accepting such justifications. (shrink)

Chinese consumers value the so-called tuji chicken (‘soil + chicken’) as a local, quality type of poultry. Because tu references both local region and the rural countryside, the tu chicken evokes a contrast with modern improved broilers and the globalized poultry industry, and exemplifies a broader ‘quality turn’ in China’s agri-food system. But what precisely makes a chicken tu (‘local’ and ‘earthy’), and how to identify one that is, are more uncertain and contested questions. Building on (...) literature in food studies, anthropology and geography that unpacks the social construction of definitions of local and quality food, this paper argues that struggles over the definition of the tu chicken are closely linked with consumer strategies for authenticating these definitions in practice. Interviews and fieldwork observations with consumers, poultry vendors and farmers in southwestern China show significant variation in how the tu chicken is defined. But in a context where China’s food safety scandals have produced a climate of food distrust, consumers are as interested in techniques of qualifying or evaluating whether or not particular chickens are tu, as they are in contesting or constructing the abstract definition of tu chickens.

The social dilemma of Chicken expresses disorderly sentiments. King Henry V reveals the importance of Chicken as a foreground strategy during Queen Elizabeth’s reign. The play parallels Henry’s French predicament with Elizabeth’s Spanish dilemma. These international crises also parallel Edward de Vere’s personal and familial experiences of Chicken. In personal terms, various events reveal Oxford’s propensity for Chicken, including his disagreements with Queen Elizabeth, his feud with Thomas Knyvet, and his desire to serve against the Armada. (...) In familial terms, French defiance of King Henry V required concerted English daring. Richard de Vere, Eleventh Earl of Oxford, exemplified the necessary determination. William Shakspere’s lineage reveals no estimable counterpart. (shrink)

We trained chickens to react to an average human female face but not to an average male face (or vice versa). In a subsequent test, the animals showed preferences for faces consistent with human sexual preferences (obtained from university students). This suggests that human preferences arise from general properties of nervous systems, rather than from face-specific adaptations. We discuss this result in the light of current debate on the meaning of sexual signals and suggest further tests of existing hypotheses about (...) the origin of sexual preferences. (shrink)

Why would anyone want there to be natural foundations for the social sciences? In a provocative essay exploring precisely that question, historian Chris Renwick uses an interwar debate featuring William Beveridge, Lancelot Hogben, and Friedrich Hayek to begin to imagine what might have been had such a program calling for biological knowledge to form the natural bases of the social sciences been realized at the London School of Economics. Yet perhaps Renwick grants too much attention to differences and “what-ifs” and (...) not enough to the historical question of “what happened” afterward. “Chickens and Eggs” offers an alternative view of this rather vexed question—one grounded in what happened, which suggests that Renwick’s concerns may be somewhat misplaced.

In recent decades, urban agriculture has drawn practitioners seeking ways to increase both environmental sustainability and social equity in their cities. The practice has also drawn criticism for the ways it reproduces inequalities based on differences of class and race. In this paper, I argue contestations around urban agriculture are part of ongoing yet shifting processes of class formation intersecting with racial differentiation, in particular the emergence of green middle-class identity. Drawing on fourteen months of ethnographic fieldwork in a small (...) city in Michigan, USA, I examine urban agriculture as a historic spatial and aesthetic practice, drawing on examples of chicken-keeping, permaculture-style gardening, and concerns with neatness and blight. By positioning urban agriculture within historical narratives of landscape aesthetics and land use policy, I demonstrate how this practice becomes bound up in the ongoing production of class distinctions and inequalities. Throughout, I draw attention to how processes of class formation unfold in ways that diverge from, or are in excess of, local gardeners’ and agriculturalists’ intentions. In conclusion, I gesture to the ways the instability and dynamism of class formation via urban agriculture presents opportunities for addressing the reproduction of race- and class-based inequalities and for nurturing more equitable and sustainable forms of urban agriculture practice.

Suppose that, for reasons of animal welfare, it would be better if everyone stopped eating chicken. Does it follow that you should stop eating chicken? Proponents of the “inefficacy objection” argue that, due to the scale and complexity of markets, the expected effects of your chicken purchases are negligible. So the expected effects of eating chicken do not make it wrong. -/- We argue that this objection does not succeed, in two steps. First, empirical data about (...) chicken production tells us that the expected effects of consuming *many* chickens are not negligible. Second, this implies that the expected effect of consuming one chicken is ordinarily not negligible. *Parity* between your purchase and other counterfactual purchases and *uncertainty* about others’ consumption behavior each tend to pull the expected effect of a single purchase toward the average large scale effect. While some purchases do have negligible expected effects, many do not. (shrink)

Global chicken production has undergone rapid industrialisation over the past century, driven by technological advances in breeding and feed efficiency, and is now among the most consolidated livestock sectors. In Bangladesh, over the past three decades, chicken production has shifted from small-scale subsistence practices to commercialised systems increasingly reliant on imported genetics. Yet, alongside this industrialisation, a significant semi-autonomous value chain centred on Sonali chickens, a locally embedded crossbred bird, has co-existed and thrived. Drawing on the Systems of (...) Provision framework, this paper examines how global and domestic market forces shape the organisation of Bangladeshi chicken production, with a particular focus on genetic control as a critical input. We show how Sonali production represents an alternative provisioning model sustained by smallholders, local markets, and publicly maintained genetics, yet its future is increasingly contested as multinational firms and domestic corporations seek to capture this market. We argue encroachment of Sonali chicken would not only erode an important ‘endogenous material culture’ but further concentrate production with consequences for market control. By highlighting genetics as an influential driver of provisioning, we contribute to broader debates on food sovereignty, regulatory governance, and livestock industrialisation. The fate of Bangladesh’s ‘golden chicken’ underscores how control over foundational technologies shapes pathways of development and autonomy within rapidly transforming food systems. (shrink)

Animal protection organizations expect their staff to understand and support high welfare standards in animal production. Relationships between Australian animal protection organization workers’ knowledge of chicken production systems, purchasing behavior, and opinion-leading behavior were investigated. Forty-five percent of knowledge questions were answered correctly. Knowledge was mostly gained from animal protection organizations and online literature. Knowledgeable respondents were more critical of both conventional and free range/organic chicken systems and were more likely to avoid eating chicken meat, but not (...) eggs. They were more likely to approach those responsible, in government or industry, about welfare issues and were more likely to discuss animal welfare issues at work and in a social setting. They were also more likely to ask questions about animal welfare standards of food provided at butchers, farmers’ markets, social meals, and restaurants/cafés. Therefore, knowledge was linked to advocacy for improved animal welfare by animal protection organization workers. (shrink)

Standard biological and philosophical treatments assume that dramatic genotypic or phenotypic change constitutes instantaneous speciation, and that barring such saltation, speciation is gradual evolutionary change in individual properties. Both propositions appear to be incongruent with standard theoretical perspectives on species themselves, since these perspectives are (a) non-pheneticist, and (b) tend to disregard intermediate cases. After reviewing certain key elements of such perspectives, it is proposed that species-membership is mediated by membership in a population. Species-membership depends, therefore, not on intrinsic characteristics (...) of an organism, but on relationship of an organism to others. A new definition of speciation is proposed in the spirit of this proposal. This definition implies that dramatic change is neither necessary nor sufficient for speciation. It also implies, surprisingly, that an organism can change species during its lifetime. (shrink)

Suppose that animals have rights. If so, may you go down to your local farm store, buy some chicks, raise them in your backyard, and eat their eggs? You wouldn't think so. But we argue, to the contrary, that you may. Just as there are circumstances in which it's permissible to liberate a slave, even if that means paying into a corrupt system, so there are circumstances in which it's permissible to liberate chickens by buying them. Moreover, we contend that (...) restrictions on freedom of movement can be appropriate for chickens, but not humans, because of the obvious differences between the interests of healthy, adult humans versus those of chickens who have been bred for human use. We also argue that egg consumption is permissible based on the plausible assumption that no one's rights are violated in their consumption, and so while there may sometimes be morally preferable uses for eggs, you do nothing unjust in eating them. If we're right, then the rights view doesn't imply that veganism is obligatory; rather, it implies that the constraints on how we source animal products, though highly demanding, are not so demanding that they can't be met.

In Metaphysics Λ7 1072b30–1073a3, Aristotle introduces a Speusippean theory according to which ‘what is most beautiful and best is not en archēi’. Through a detailed analysis of the passage, I argue that Aristotle’s refutation of Speusippus’ thesis is favoured by the introduction of the seed example, which conflates both ontological and temporal priority. The elements gathered from the analysis of Aristotle’s polemical strategy will support a broader conclusion: Speusippus’ reason not to characterise his principle(s) as (the) good is related to (...) the problematic relationship Forms and sensibles had within Plato’s account, or, in other words, participation.

In lieu of an abstract, here is a brief excerpt of the content:Papirius and the Chickens, or Machiavelli on the Necessity of Interpreting ReligionJohn M. Najemy*No aspect of Machiavelli’s thought elicits a wider range of interpretations than religion, and one may wonder why his utterances on this subject appear to move in so many different directions and cause his readers to see such different things. One reason is of course his famous challenge to conventional piety in the advice to princes (...) (in chapter 18 of The Prince) that, while it is important to appear to be “all compassion, faith, integrity, humanity, and religione, and there is nothing more necessary for a prince than to appear to have the last of these,” these “qualities” can actually be “damaging” if a prince insists on observing them at all times. For it is sometimes necessary to act “against faith, against charity, against humanity, and against religione.” 1 Machiavelli probably never wrote more famous or infamous words than these, even though they express an obvious, and hardly original, truth about all politics. But the world of the later sixteenth- and seventeenth-century reformations and religious absolutisms could not tolerate such honesty, and Machiavelli’s reputation was quickly tarred with accusations of devilish immorality by the very societies that thought it was godly to burn heretics. On the issue of religion Machiavelli became, and to some extent remains, a convenient scapegoat often blamed for the decline of religion in the modern world, all of which has no doubt intensified the polemical and ideological nature of the debates surrounding his views of religion in general and Christianity in particular. [End Page 659]The polar positions in the interpretation of Machiavelli’s ideas about religion are represented by Leo Strauss and Sebastian de Grazia. For Strauss, Machiavelli was a “teacher of evil,” a “blasphemer,” and a purveyor of lessons of a “diabolical” and “soulless character” whose purpose was to sabotage the heritage of thought and morality inherited from both Christianity and Greek philosophy. 2 De Grazia, by contrast, has recently given us a Machiavelli who “discourses about God always in the conventional reverent attitude,” who “never questions that there is good and evil,” and who, “by associating virtuous political action with grace and glory... argues that through this kind of active and political virtue men conform to God’s desire.” “Behind Niccolò’s insistence on political action,” says de Grazia, “stands God. He grants His grace when it is earned—in political coin.” 3 Part of the fascination of Machiavelli scholarship is the mystery of how this most outspoken and direct of political thinkers—a writer who pulled no punches and minced no words—could be the common referent of such wildly different readings. But it is equally curious to observe how uncannily these extreme positions mirror each other. Both give us true believers, one in the Word, the other in the subversion of the Word; and in both cases a believer who is always of a piece, true to himself, and possessed of an unshakeable commitment—whether positive or negative—toward the transcendent truth of Christianity. In short, for all the obvious differences, the similarities between Strauss’s “diabolical” Machiavelli and de Grazia’s reverent “friend of God” remind one of the old myth that devils are after all only fallen angels.The papers in this forum should certainly remove any doubt about the importance of religion in Machiavelli’s thought. They remind us of the prominence of religious language and examples in Machiavelli’s texts: his call for the “redemption” of Italy in the last chapter of The Prince; the esteem in which he holds the heads and founders of religions, whom he declares, in Discourses 1.10, to be the most praised of all famous men; the crucial appeal to the figure of Moses as the prototype of both founders of states and liberators of enslaved peoples; the central role that Machiavelli attributes to religion among the factors responsible for Rome’s power, unity, and political success; and his provocative critique of Christianity, which leads him, in a number of places, to blame the Christian faith for the relative weakness of both modern states and the modern ethic of citizenship. 4 The authors...

Wether the chicken or the egg came first, is not only a mind-boggling but a substantial question. Its answer depends on the biological background theory one assumes. I review recent work on the topic (by Teichmann, Sorensen, Waller and Raatzsch) and resolve some of the disputes between these authors by borrowing from Aristotle the distinction between chicken-producing eggs. I then introduce the concept of a quasi-species to make explicit the vagueness involved in species-terms and prove 13 different priority-claims (...) within a Darwinian framework. (shrink)

This chapter claims that a productive dialogue can and should be forged between Freudian–Lacanian psychoanalytic teachings and critical evaluations of nonhuman complexes and elements—such as material objects, uncanny things, climate, animals, the text, the machine, and so on. With an overview of crucial overlapping themes, it situates the various chapters of this book by positing a question modeling the essential link between psychoanalysis and the nonhuman turn: What does the nonhuman want?

This paper aims to better motivate the naturalization of metaphysics by identifying and criticizing a class of theories I call ’free range metaphysics’. I argue that free range metaphysics is epistemically inadequate because the constraints on its content—consistency, simplicity, intuitive plausibility, and explanatory power—are insufficiently robust and justificatory. However, since free range metaphysics yields clarity-conducive techniques, incubates science, and produces conceptual and formal tools useful for scientifically engaged philosophy, I do not recommend its discontinuation. I do recommend, however, ending the (...) discipline’s bad faith. That is, I urge that free range metaphysics not be taken to have fully satisfactory epistemic credentials over and above its pragmatic ones. (shrink)

Edward de Vere’s Ramist sensitivity toward dialectical, strategical, and rhetorical issues matched his commitment to the logic of cause and effect. King Henry V exhibits that combination of sensitivity and determination: game-theoretic bankers must retain their strategic grip. Despite King Henry’s example, English politicians subsequently lost sociopolitical control, owing to a lack of strategic nous among King Henry VI’s advisors. They failed that requirement in pursuing self-defeating rationales. Mary Tudor’s accession indicted the managers of King Edward VI’s minority for their (...) similar failure. Edward de Vere, Seventeenth Earl of Oxford, appreciated this comparison. Two of his own supervisors, Thomas Smith and William Cecil, as important figures to “The Boy King,” had suffered political ostracism under Mary. (shrink)

A central aspect of the relation between biosemiotics and biology is investigated by asking: Is a biological concept of function intrinsically related to a biosemiotic concept of sign action, and vice versa? A biological notion of function (as some process or part that serves some purpose in the context of maintenance and reproduction of the whole organism) is discussed in the light of the attempt to provide an understanding of life processes as being of a semiotic nature, i.e., constituted by (...) sign actions. Does signification and communication in biology (e.g., intracellular communication) always presuppose an organism with distinct semiotic or quasi-semiotic functions? And, symmetrically, is it the case that functional relations are simply not conceivable without living sign action? The present note is just an introduction to a project aiming at elucidating the relations between biofunction and biosemiosis. (shrink)

Studies with captive fowl have revealed that they possess greater cognitive capacities than previously thought. We now know that fowl have sophisticated cognitive and communicative skills, which had hitherto been associated only with certain primates. Several theories have been advanced to explain the evolution of such complex behavior. Central to these theories is the enlargement of the brain in species with greater mental capacities. Fowl present us with a conundrum, however, because they show the behaviors anticipated by the theories but (...) do not have the expected changes in the brain. Consequently fowl present two challenges of interest to us here. One is a scientific challenge to explain their remarkable capabilities. The other is an ethical challenge regarding our treatment of animals with higher cognitive skills. (shrink)

This paper argues that the long-standing predominance of a particular approach to science neither makes it uniquely scientific nor superior to rival approaches. To do so it examines the dominant scientific explanation of the 17th and early 18th centuries: the mechanical philosophy. The mechanical philosophy episode demonstrates the fragility of even the most entrenched scientific wisdoms and provides encouragement for out-of-step scholars everywhere.

Welfare-friendly outdoor poultry husbandry systems are associated with potentially higher public health risks for certain hazards, which results in a dilemma: whether to choose a system that improves chicken welfare or a system that reduces these public health risks. We studied the views of citizens and poultry farmers on judging the dilemma, relevant moral convictions and moral arguments in a practical context. By means of an online questionnaire, citizens (n = 2259) and poultry farmers (n = 100) judged three (...) practical cases, which illustrate the dilemma of improving chicken welfare or reducing public health risks for Campylobacter, avian influenza and dioxin. Furthermore, they scored the importance of moral arguments and to what extend they agreed with moral convictions related to humans and chickens. Citizens were more likely than farmers to choose a system that benefits chicken welfare at the expense of public health. These different judgments could be explained by differing moral convictions and valuations of moral arguments. Judgments of citizens and farmers were associated with moral arguments and convictions, predominantly with those regarding the value of chickens and naturalness. Citizens agreed stronger with moral convictions regarding the intrinsic value of chickens and regarding naturalness than farmers did, while farmers agreed stronger with conviction regarding fairness. We argue that opinions of citizens and farmers are context-dependent, which may explain the differences between these groups. It implies that opinions of different stakeholder groups should be considered in order to achieve successful innovations in poultry husbandry, which are supported by society. (shrink)

This study used urban legends to examine the effects of a cognitive bias for content which evokes higher levels of emotion on cumulative recall. As with previous research into content biases, a linear transmission chain design was used. One-hundred and twenty participants, aged 16–52, were asked to read and then recall urban legends that provoked both high levels and low levels of emotion and were both positively and negatively valenced. The product of this recall was presented to the next participant (...) in a chain of three generations. A significant effect of emotion level on transmission fidelity was found with high emotion legends being recalled with significantly greater accuracy than low emotion legends. The emotional valence of a legend was found not to have any effect on cumulative recall; thus emotional biases in recall go beyond disgust and can incorporate other emotions such as amusement, interest and surprise. This study is the first to examine an emotion bias in cultural transmission as a general phenomenon without focusing on the emotion of disgust. (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.

Mealey's interesting interpretation of sociopathy is based on an inappropriate two-person game model.

Here I critique the approach often seen in bioethics, termed "Chicken Little bioethics," which emphasizes only the potential risks of novel therapies, using fecal microbiota transplant (FMT) as a case study. I argue that, instead of cataloging hypothetical risks, bioethicists should focus on establishing an ethical framework for FMT based on justice, beneficence, nonmaleficence, and autonomy. The essay advocates for empirical risk-benefit analysis through initiatives like the FMT registry, which tracks patient outcomes to better assess the actual risks and (...) benefits compared to antibiotic alternatives. Additionally, I address challenges related to informed consent, donor selection, and access to FMT, underscoring the need for balanced policies that consider both patient safety and the equitable availability of this promising therapy. In the end, I call for a regulatory approach that fosters responsible innovation while allowing FMT and similar bacteriotherapies to be integrated safely and effectively into medical practice.

As a philosopher, Amy Olberding is trained to wrestle with abstraction. But when she takes over her ancestral family farm in the Ozarks, her experience turns far more earthy. Her double life in philosophy and farming worked well enough, for a time. But then she tried to write a philosophy book about grief. Olberding's profession prepared her to write a scholarly book, but left her ill-equipped to do so among the haunting traces of her ancestors: the grandfather who could fix (...) anything, the uncle who cautioned against letting your brains show, and the grandmother who once had all her chickens killed to conceal her hillbilly origins. Like her grandmother, Olberding was adept at killing chickens, at least metaphorically, taking on the marks of class and education expected of professors. But her efforts to write dispassionately about grief from a farm populated with family ghosts quickly foundered. Instead, Olberding presents a lyrical mosaic that refuses to shy away from the acute confusions that come with loss. Insistently joining farm life to learning and Ozark ancestors to philosophers, Olberding offers evocative meditations on community and tradition, the contradictions of mental and manual labor, the worlds of urbane airs and country speech, and describes a life of the mind slowly giving way to raw experience. _Kill All the Chickens_ is the book you get when loss is less a problem to solve than a place where you live. Most of all, it is an effort to revive some chickens, to let the earthy stuff of sorrow sometimes mess up the cleaner wisdoms philosophy might offer. (shrink)

The intensification of farm animal welfare debate has led to an increasing number of certification schemes covering this issue; however, there are concerns about the contribution of these schemes in improving welfare. The aims of this study were to identify certification schemes for broiler chicken welfare at farm level in Brazil, to investigate the extent of nutritional, environmental, health and behavioral indicators within the schemes and to analyze the content of scheme and the capacity to promote continuous improvement on (...) certified farms. GLOBALG.A.P.® and Certified Humane® were the only schemes observed, corresponding to 2.1 % of broiler chicken farms in Brazil. Environmental and health indicators were in greater number, and the requirements classified as behavioral indicator were commonly related to the resolution of low levels of animal welfare. Both schemes were in accordance with the European Food Safety Authority recommendations for farmer training, birds and buildings inspection, temperature control, air and litter quality, stocking density and lighting. The selection of breeds and the use of animal-based indicators needs to be improved, as well the inclusion animal welfare objectives and management review as part of continuous improvement. Welfare certification is a potential market to be developed in Brazil. Overall, assessed schemes may potentially enhance animal welfare at farm level by including new concepts and practices. It is desirable to increase the number of certified farms in Brazil and that certification schemes be critically analyzed on a regular basis regarding their content to meet new demands and to include updates from scientific research.

A common view is that the truth of multiple realization—e.g., about psychological states—entails the truth of functionalism. This is supposed to follow because what is multiply realized is eo ipso realized. I argue that view is mistaken by demonstrating how it misrepresents arguments from multiple realization.
