The trajectory of the public discourse on agriculture in the twentieth century presents an interesting pattern:shortly after World War II, the manner in which farming and farmers were discussed underwent a profound shift. This rhetorical change is revealed by comparing the current debate on farmland preservation with a tradition of agricultural discourse that came before, known as “agrarianism.” While agrarian writers conceived of farming as a rewarding life, a public good, and a source of moral virtue, current writers (...) on farmland preservation speak of farming almost entirely in utilitarian terms describing its productive capacity and its economic returns. Proponents of farmland preservation use essentially the same underlying framework as critics of preservation:n “economic utilitarian” paradigm that purports to eschew normative values and evaluate land use decisions based on economic criteria only. I argue that, despite their good intentions, farmland preservationists are doomed to piecemeal victories at best, because their arguments, which rely on a utilitarian justification and disregard the agrarian ethic, are inadequate. Without expanding its focus beyond farmland to encompass farming and farmers, the movement risks losing both integrity and effectiveness. (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)

Agriculture in the Netherlands is a critical industry, in terms of both its share of available land and its importance to the Dutch economy. Cultural-technical improvements and intensification of land use have resulted in increased productivity, but have also threatened vulnerable and valuable natural habitats and landscapes. TheRelatienota, a government report issued in 1975, introduced an environmental policy implemented by regulation in 1983 and 1988. Under this policy,Relatienota areas (management areas and reserves) are established. Farmers in management areas voluntarily enter (...) private contracts (management agreements) with the government, in which they promise to tailor agricultural production to nature and landscape conservation. By compensating farmers for activities that maintain existing natural conditions, management agreements provide the incentive for extraordinary efforts to protect agricultural environments for valuable plant and animal species. Particularly sensitive natural areas, where environmental values are incompatible with economic farming, are identified as reserves, and the land is purchased for specialized management.AlthoughRelatienota policy has been implemented on a limited number of hectares, it is an important component of the efforts in the Netherlands to protect and preserve vulnerable natural areas. As a model of negotiated cooperation between government, farmers, and nature protection interests, its success may encourage other nations in the Economic Community to use private contracts to further societal goals.

While questions about the environmental sustainability of contemporary farming practices and the socioeconomic viability of rural communities are attracting increasing attention throughout the US, these two issues are rarely considered together. This paper explores the current and potential connections between these two aspects of sustainability, using data on community members’ and farmers’ views of agricultural issues in California’s Central Valley. These views were collected from a series of individual and group interviews with biologically oriented and conventional farmers as well as (...) community stakeholders. Local marketing, farmland preservation, and perceptions of sustainable agriculture comprised the primary topics of discussion. The mixed results indicate that, while many farmers and community members have a strong interest in these topics, sustainable community development and the use of sustainable farming practices are seldom explicitly linked. On the other hand, many separate efforts around the Valley to increase local marketing and agritourism, improve public education about agriculture, and organize grassroots farmland preservation initiatives were documented. We conclude that linking these efforts more explicitly to sustainable agriculture and promoting more engagement between ecologically oriented farmers and their communities could engender more economic and political support for these farmers, helping them and their communities to achieve greater sustainability in the long run.

A Rural Sanctuary is defined as an area where farming activity creates habitats for a diverse assemblage of species that find a broad spectrum of resources along the season. A Rural Sanctuary is proposed as a new model of land management to protect nature inside a framework of cultural identity and agro-forestry sustainability. A Rural Sanctuary has a dual mission: to provide immaterial and material resources for people, and to guarantee living spaces to a large assemblage of species. A Rural (...) Sanctuary represents an ecosemiotic agency in which human eco-fields and animal eco-fields interact. This reflects a model that is rooted in the Mediterranean region, where for long time people and nature have harmoniously lived in strict contact and inter-dependence. An example of a Rural Sanctuary from this region is proposed to demonstrate the amazing diversity of living beings observed on only few hectares of farmland. A Rural Sanctuary offers possibilities to educate people about a more sustainable approach to nature, and it represents a unique place to investigate animal perception. Finally, between the different approach to certify the validity of a Rural Sanctuary, sound recording is suggested as one of the less invasive methods for ecological investigation and long-term monitoring.

Buddhist texts generally prohibit the killing of all sentient beings. This is certainly the case in vinaya texts, which contain strict guidelines on the preservation of all human and animal life. When these vinaya texts were translated into Chinese, they formed the core of Buddhist behavioural codes, influencing both monastic and lay followers. Chinese vinaya masters, such as Daoxuan?? and Yijing??, wrote extensive commentaries and accounts, introducing Indian concepts into the Chinese environment. In this paper, we focus on an (...) often neglected aspect of inflicting harm on sentient beings: namely, the injury that may be caused to some of the world’s smallest animals — insects. Some insects produce economically valuable products, such as silk and honey; others, such as mosquitoes and bedbugs, are annoying or dangerous; and still others are innocent victims of essential human activities, such as earthworms that are killed when farmland is tilled. Yet, all of these are sentient beings that — according to Buddhist principles — should not be harmed or killed. What this implies for Chinese vinaya masters, and especially the highly influential Daoxuan, is the core question of this paper. As we will see, their responses are mixed, but they always attempt to remain true to the basic principles of Buddhism. (shrink)

This article looks at how imaginaries of land and climate play a role in farmland investment discourses and practices. Foreign farmland investors in the fertile black earth region of Russia and Ukraine have ‘celebrated’ soil fertility while largely ignoring climatic factors. The article shows a centuries-long history of outsiders coming to the region lured by the fertile soils, while grossly underestimating climate which has had disastrous implications for farm viability and the environment. Comparisons with historical and contemporary literature (...) on other regions suggest that the underestimation of climatic risks by newcomers is remarkably prevalent in resource frontiers. (shrink)

This article critically analyzes the assumption that land is becoming increasingly scarce and that, therefore, farmland values are bound to rise across the globe. It investigates the process of land value creation, as well as its flipside: value erosion and stagnation, looking at the various mechanisms involved in each. As such, it is a study of how the financialization of agriculture affects the process of land commoditization. I show that, for farmland to be turned into an asset, a (...) whole range of conditions have to be fulfilled, presenting a typology of asset making in the context of farmland. Asset making, like commoditization, is a process of assemblage, and it is less straightforward and less stable than generally assumed. Further, I argue that ‘asset making’ is not a one-way process. The article is based on an analysis of global data on land values and the case of farmland investment in post-Soviet farmland. (shrink)

Structural changes in the agriculture and food system have resulted in larger but fewer farms, while increasing populations in urban areas have pushed development into rural areas. Despite these changes, little research has examined the concern of individuals with regards to loss of farmland and how this may vary based on geography. Building on Bell’s argument that the rural–urban continuum still exists and remains an important part of rural residents’ identity, in this article we examine residents’ concern over loss (...) of farmland as a result of urban growth. We pay particularly close attention to urban–rural differences over concern with loss of farmland. Utilizing survey data collected from over 400 households in the Treasure Valley, a region of the western United States, our results indicate that rural residents show greater levels of concern with farmland loss when compared to their urban counterparts.

Biodiversity is a valuable resource that supports sustainability within agricultural systems, yet in contradiction to this agriculture is recognised as a contributor to biodiversity loss. Agricultural advisory services are institutions that support sustainable agricultural development, employing a variety of approaches including farmer discussion groups in doing so. This study evaluates the impact of a farmland biodiversity management (FBM) communication strategy piloted within Irish farmer discussion groups. A sensemaking lens was applied in this objective to gain an understanding of how (...) this strategy could create an actionable space for FBM promotion amongst farmers. The strategy was piloted with six Irish dairy farmer discussion groups, after which focus groups were conducted with members of these groups. Additionally, baseline and endline surveys were completed by the members to determine their knowledge, attitude and on-farm practices relating to FBM. Analysis of the focus group data identified that the communication strategy supported the affordance of sensemaking with respect to FBM. Analysis of the data from the baseline and endline surveys relating to knowledge, attitudes and practices found that engaging with the communication strategy promoted farmers to improve their attitude in relation to FBM. Results from this study provide important lessons for agricultural advisory services to support farmers in incorporating FBM into the overall management of their farms and, in turn, to promote the improvement of farmland biodiversity and contribute to a sustainable future.

Current facts about soil erosion, groundwater “mining,” and impact of toxic substances suggest a resource crisis in our farming system. Yet traditional checks on the exploitation of farmland, capsulized in the “stewardship ethic,” proceed from too limited a viewpoint to adequately address the root of the exploitation and proffer an alternative. After briefly examining the stewardship ethic, I consider the developmentof a “partnership ethic” to guide the use of land for farming which builds its essential elements out of the (...) reflections of feminist thinkers on the relationship between humankind and nature. Instead of using “rights” language to express the ethic, I develop a theory of appropriate use analogous to the appropriate use of another person’s capabilities-i.e., that such moral use should respect and not destroy the other and that it should return something of value to the other in exchange for the use. Finally, those principles are examined for their practical implications for farmland use and national farm policy. (shrink)

Some patients who have been diagnosed as “dead by neurologic criteria” continue to exhibit certain brain functions, most commonly, neuroendocrine functions. This preservation of neurologic function after the diagnosis of “brain death” or “brainstem death” is an ongoing source of controversy and concern in the medical, bioethics, and legal literatures. Most obviously, if some brain function persists, then it is not the case that all functions of the entire brain have ceased and hence, declaring such a patient to be (...) “dead” would be a false positive, in any nation with so-called “whole brain death” laws. Furthermore, and perhaps more concerning, the preservation of any brain function necessarily entails the preservation of some amount of brain perfusion, thereby raising the concern as to whether additional areas of neural tissue may remain viable, including areas in the brainstem. These and other considerations cast significant doubt on the reliability of diagnosing either “brain death” or “brainstem death.”. (shrink)

The aim of this article was to obtain an understanding of what is experienced as human dignity by nurses in surgical practice. In order to obtain experiences from practice, the critical incident technique was chosen. A total of 11 nurses from surgical practice wrote 49 stories about positive and negative incidents. The text was analysed using hermeneutical text interpretation. The findings revealed patient dignity in terms of preserved dignity, that is, healthcare professionals paid attention to the patient. Nurses experienced preserved (...) dignity when healthcare professionals allowed the patient to tell their story, allowed themselves to get close to the patient and in turn received the patient’s trust. Violated dignity included circumstances when the nurses were forced to see what they did not want to see. Nurses experienced violated dignity when healthcare professionals behaved rudely towards the patient, acted as if he or she was invisible or humiliated the patient at the end of life. (shrink)

In this essay I will examine the changing historical relationship between two fundamentally modern concepts: self-preservation and self-ownership. These two concepts have served a dual function in modernity. On the one hand, they are crucial parts of the theoretical underpinning of liberalism: the natural law of self-preservation is the foundation of the rational inclination to form civil society (e.g., Hobbes); and self-ownership provides the foundation for the liberal (i.e., Lockean) notion of private property. But on the other hand, (...) these two concepts serve much more than a theoretical purpose; they also perform a duty in what I would like to call, borrowing Foucault's phrase, a modern technology of the self. At this level, the concepts of self-ownership and self-preservation shape individuals to follow certain routines in their behavior, to treat their bodies in specific ways, to organize their time in a particular fashion. In performing these routines, individuals participate in the collection and dissemination of that knowledge of individual bodies and groups of bodies which, as Foucault and Arendt in their different ways revealed, is endemic to modernity.

We show that the existential preservation theorem fails for two-variable first-order logic FO2. It is known that for all k ≥ 3, FOk does not have an existential preservation theorem, so this settles the last open case, answering a question of Andreka, van Benthem, and Németi. In contrast, we prove that the homomorphism preservation theorem holds for FO2.

We define notions of homomorphism, submodel, and sandwich of Kripke models, and we define two syntactic operators analogous to universal and existential closure. Then we prove an intuitionistic analogue of the generalized (dual of the) Lyndon-Łoś-Tarski Theorem, which characterizes the sentences preserved under inverse images of homomorphisms of Kripke models, an intuitionistic analogue of the generalized Łoś-Tarski Theorem, which characterizes the sentences preserved under submodels of Kripke models, and an intuitionistic analogue of the generalized Keisler Sandwich Theorem, which characterizes the (...) sentences preserved under sandwiches of Kripke models. We also define several intuitionistic formula hierarchies analogous to the classical formula hierarchies $\forall_n (= \Pi^0_n)$ and $\exists_n (=\Sigma^0_n)$ , and we show how our generalized syntactic preservation theorems specialize to these hierarchies. Each of these theorems implies the corresponding classical theorem in the case where the Kripke models force classical logic. (shrink)

A popular and plausible response against Laudan's “pessimistic induction” has been what I call “preservative realism,” which argues that there have actually been enough elements of scientific knowledge preserved through major theory‐change processes, and that those elements can be accepted realistically. This paper argues against preservative realism, in particular through a critical review of Psillos's argument concerning the case of the caloric theory of heat. Contrary to his argument, the historical record of the caloric theory reveals that beliefs about the (...) properties of material caloric, rejected by subsequent theories, were indeed central to the successes of the caloric theory. Therefore caloric remains a favorable case for Laudan. Further, I argue that even confirmed cases of preservation do not warrant an inference to truth. (shrink)

We prove the preservation theorems for NATP; many of them extend the previously established preservation results for other model-theoretic tree properties. Using them, we also furnish proper examples of NATP theories which are simultaneously TP2 and SOP. First, we show that NATP is preserved by the parametrization and sum of the theories of Fraïssé limits of Fraïssé classes satisfying strong amalgamation property. Second, the preservation of NATP for two kinds of dense/co-dense expansions, i.e. the theories of lovely (...) pairs and of [Formula: see text]-structures for geometric theories, and dense/co-dense expansion on vector spaces is proved. Next, we prove the preservation of NATP for the generic predicate expansion and the pair of an algebraically closed field and its distinguished subfield; for the latter, not only NATP, but also the preservation of NTP1 and NTP2 is considered. Finally, we present some proper examples of NATP theories using the results proved in this paper, including the parametrization of DLO and the expansion of an algebraically closed field by adding a generic linear order. In particular, we show that the model companion of the theory of algebraically closed fields with circular orders (ACFO) is NATP. (shrink)

The nature of farming is – still – an essentially biological, and thus volatile, system, which poses substantial challenges to its integration into financialized capitalism. Financial investors often seek stability and predictability of returns that are hardly compatible with agriculture – but which are increasingly seen as achievable through data and digital farming technologies. This paper investigates how farmland investment brokers engage with, perceive, and produce farming data for their investors within a co-constructive process. Tackling land’s ‘stubborn materiality’ for (...) investment, I argue, has material and immaterial components: it includes the re-imagination of farming as a financial asset that delivers reliable income streams for investors; and the re-engineering of farmland’s concrete materialities with digital farming technologies. Farmland investment brokers develop investor-suitable farmland imaginaries, underpinned by storytelling as well as the calculative ‘evidence’ of (digital) data. At the same time, digital technologies have become a key tool for transforming farms into ‘investment grade assets’ endowed with the rich data on farm performance and financial returns requested by investors. I conclude that the assetization and digitization of farmland need to be seen as closely intertwined and mutually reinforcing processes and identify key areas for future research on this intersection.

In order to prove the validity of logical rules, one has to assume these rules in the metalogic. However, rule-circular ‘justifications’ are demonstrably without epistemic value. Is a non-circular justification of a logical system possible? This question attains particular importance in view of lasting controversies about classical versus non-classical logics. In this paper the question is answered positively, based on meaning-preserving translations between logical systems. It is demonstrated that major systems of non-classical logic, including multi-valued, paraconsistent, intuitionistic and quantum logics, (...) can be translated into classical logic by introducing additional intensional operators into the language. Based on this result it is argued that classical logic is representationally optimal. In sec. 6 it is investigated whether non-classical logics can be likewise representationally optimal. The answer is predominantly negative but partially positive. Nevertheless the situation is not symmetric, because classical logic has important ceteris paribus advantages as a unifying metalogic.

In this paper, we aim at explaining the relevance of thought experiments in philosophy and the history of science by describing them as particular instances of two categories of creative thinking: metaphorical reasoning and abductive cognition.

Elaborating this thesis will allow us to explain the wonder that philosophers of (...) science have consistently shown for TEs, as well as the high functionality of TEs in the creative aspects of scientific and philosophical praxis.

. This paper examines the underpinnings of the preservationist approach to characterizing inference relations. Starting with a critique of the ‘truth-preservation’ semantic paradigm, we discuss the merits of characterizing an inference relation in terms of preserving consistency. Finally we turn our attention to the generalization of consistency introduced in the early work of Jennings and Schotch, namely the concept of level.

In this paper we study intermediate logics between the logic G≤∼, the degree preserving companion of Gödel fuzzy logic with involution G∼ and classical propositional logic CPL, as well as the intermediate logics of their finite-valued counterparts G≤n∼. Although G≤∼ and G≤ are explosive w.r.t. Gödel negation ¬, they are paraconsistent w.r.t. the involutive negation ∼. We introduce the notion of saturated paraconsistency, a weaker notion than ideal paraconsistency, and we fully characterize the ideal and the saturated paraconsistent logics between (...) G≤n∼ and CPL. We also identify a large family of saturated paraconsistent logics in the family of intermediate logics for degree-preserving finite-valued Łukasiewicz logics. (shrink)

The development and application of artificial intelligence (AI) technology has raised many concerns about privacy violations in the public. Thus, privacy-preserving computation technologies (PPCTs) have been developed, and it is expected that these new privacy protection technologies can solve the current privacy problems. By not directly using raw data provided by users, PPCTs claim to protect privacy in a better way than their predecessors. They still have technical limitations, and considerable research has treated PPCTs as a privacy-protecting tool and focused (...) on possible technical improvements. In this article, we argue that PPCTs cannot effectively protect privacy in the narrow sense due to their technical limitations. Moreover, although these shortcomings could be remedied, they still fall into a paradox because their aim is to protect privacy, but they could reveal private information from users. This paradox of privacy protection not only aggravates the social impact arising from AI privacy issues but may also make the current privacy protection lose its meaning, resulting in a situation in which privacy protection is useless.

This paper provides an analysis of U.S. farmland owners, operators, and workers by race, ethnicity, and gender. We first review the intersection between racialized and gendered capitalism and farmland ownership and farming in the United States. Then we analyze data from the 2014 Tenure and Ownership Agricultural Land survey, the 2012 Census of Agriculture, and the 2013–2014 National Agricultural Worker Survey to demonstrate that significant nation-wide disparities in farming by race, ethnicity and gender persist in the U.S. In (...) 2012–2014, White people owned 98% and operated 94% of all farmland. They generated 98% of all farm-related income from land ownership and 97% of income from farm owner-operatorship. Meanwhile, People of Color farmers were more likely to be tenants rather than owners, owned less land, and generated less farm-related wealth per person than their White counterparts. Hispanic farmers were also disproportionately farm laborers. In addition to racial and ethnic disparities, there were disparities by gender. About 63% of non-operating landowners, 86% of farm operators, and 87% of tenant farmers were male, and female farmers tended to generate less income per farmer than men. This data provides evidence of ongoing racial, ethnic and gender disparities in agriculture in the United States. We conclude with a call to address the structural drivers of the disparities and with recommendations for better data collection. (shrink)

With the increasing volume of web services in the cloud environment, Collaborative Filtering- based service recommendation has become one of the most effective techniques to alleviate the heavy burden on the service selection decisions of a target user. However, the service recommendation bases, that is, historical service usage data, are often distributed in different cloud platforms. Two challenges are present in such a cross-cloud service recommendation scenario. First, a cloud platform is often not willing to share its data to other (...) cloud platforms due to privacy concerns, which decreases the feasibility of cross-cloud service recommendation severely. Second, the historical service usage data recorded in each cloud platform may update over time, which reduces the recommendation scalability significantly. In view of these two challenges, a novel privacy-preserving and scalable service recommendation approach based on SimHash, named SerRecSimHash, is proposed in this paper. Finally, through a set of experiments deployed on a real distributed service quality dataset WS-DREAM, we validate the feasibility of our proposal in terms of recommendation accuracy and efficiency while guaranteeing privacy-preservation.

This article examines the philosophical issues that arise when preserving urban geological sites or urban geosites. These are preserved not only because of their geological value but also because of aesthetic, cultural, and economic reasons. To do so, it examines the geosite constituted by Olot and its surroundings, a city in Spain that extends amid four dormant volcanoes. It explores the metaphysical paradox that these geosites have become what they are due to the preservation of destruction: human-caused interventions, mostly (...) extraction of materials and exploitation of the land, are precisely what made these geosites visible as sites worth preserving and determining their metaphysical status. It further explores the preservation criteria and shows how they have determined the status of the geosite. Second, it shows how in such urban geosites the collapse of two diametrically opposed conceptions of time – the geological eon and the lived human time – occurs. Lastly, it discusses aesthetic aspects of such geosites by considering aesthetic experience as a primarily cognitive endeavor and shows how metaphysical, epistemological, and aesthetic issues of preservation of geosites are inextricably linked.

It is argued that the preservation of truth by an inference relation is of little interest when premiss sets are contradictory. The notion of a level of coherence is introduced and the utility of modal logics in the semantic representation of sets of higher coherence levels is noted. It is shown that this representative role cannot be transferred to first order logic via frame theory since the modal formulae expressing coherence level restrictions are not first order definable. Finally, an (...) inference relation, calledyielding, is introduced which is intermediate between the coherence preservingforcing relation introduced elsewhere by the authors and the coherence destroying, inference relation of classical logic.

On July 2021, the UK High Court of Justice heard the Case CO/2066/2020 on the application of Heidi Crowter who lives with Down’s syndrome, and Máire Lea-Wilson whose son Aidan has Down’s syndrome. Crowter and Lea-Wilson, with the support of the disability rights campaign, ‘Don’t Screen Us Out’, have been taking legal action against the Secretary of State for Health and Social Care (the UK Government) for a review of the 1967 Abortion Act: the removal of section 1(1)(d) making termination (...) of pregnancy lawful for ‘severe’ fetal indications detected after 24 weeks' gestation. On 23 September 2021, the High Court dismissed the claim. This action came at a time when non-invasive prenatal testing (NIPT) was introduced into the NHS England Fetal Anomaly Screening Programme for the trisomies 21, 13 and 18. The implementation of NIPT has been heavily criticised, in particular by ‘Don’t Screen Us Out’ campaigners, for increasing fetal selection and discrimination of people living with disabilities. The case of Crowter and Lea-Wilson echoes debates in other European countries such as in France and Germany, where the introduction of NIPT in the public healthcare system has provoked equally vehement public reactions and discussions. The comparison between these three countries allows contextualising the public discourses around NIPT and the ground for termination of pregnancy in relation to different socio-cultural and political contexts. We examine how each country, and particularly England, deals with the conflict between the principles of promoting the rights of people living with disabilities and preserving women’s reproductive autonomy.

Should we preserve nature or revolt in order to protect “the living” (“le vivant”)? At first sight, this invites a comparison between two ways and means of protecting nature. However, this article will defend the thesis that these two methods of protecting nature do not rest upon the same conception of our position, as human beings, towards the living. Indeed, in the end, we find an underlying opposition between nature, conceived as savage or as radical alterity (often inspired by the (...) culturally loaded notion of wilderness, as found in the politics of preservation of vulnerable natural spaces) and the notion of “the living.” I intend to use the concept of the living in order to emphasize “ordinary nature” and our strong connection with all other living things. This reflection will enable me to defend the connection between the fight for environmental justice (namely revolt or resistance movements on the part of the poorest populations defending their living environment and their resources against an unequal production system) and the struggle for the protection of vulnerable living spaces and species.

Richard Bradley has initiated a new debate, with Brian Hill and Jake Chandler as further participants, about the implications of a number of so-called triviality results surrounding the Ramsey test for conditionals.

I question the philosophical method of postulation that was (...) applied in the new debate, and instead base my arguments on explicit representations of belief states and canonical constructions of belief state revisions.

Many arguments are affected by context sensitivity, because they include sentences that have different truth conditions in different contexts. Therefore, it is natural to think that a general criterion for evaluating arguments must take context sensitivity into account. One way to give substance to that thought is provided by the definition of validity offered by David Kaplan within his theory of indexicals. However, the route indicated by Kaplan is hindered by a problem whose importance is often underestimated. This paper explores (...) a different route, and outlines a definition of validity that does not run into that problem. Its moral is that Kaplan's definition is not the only plausible definition. This is not to say that the definition outlined is the only plausible definition or that it is correct in some absolute sense. There might be equally important problems with it that the paper does not take into account. But until such problems are found and brought up, the departure from Kaplan's route remains a viable option. (shrink)

The issues of human cloning and stem cell retrieval are inseparable in circumstances in which the rationale of self-preservation may be invoked as a negative right. I apply this rationale to a hypothetical case in which cloning is necessary to preserve the bodily integrity or life of an individual. Self-preservation as moral integrity is examined in a narrower context, i.e., as applicable to those for whom deliberate termination of embryonic life is morally-problematic. This issue is addressed through comparison (...) with two paradigms commonly used in support of clinical practice: the distinction between letting die and killing, and the permissibility of vital organ retrieval after death. Although these paradigms are questionable in their own right, they offer a rationale by which scientists and clinicians may respect the negative right to moral integrity of those with whom they disagree.

BackgroundWhile fertility preservation is recommended practice for paediatric oncology patients, it is increasingly being considered for transgender children and young people in paediatric care. This raises ethical issues for clinicians, particularly around consent and shared decision-making in this new area of healthcare.MethodsA systematic review of normative literature was conducted across four databases in June 2020 to capture ethical considerations related to fertility counselling and preservation in paediatric transgender healthcare. The text of included publications was analysed inductively, guided by (...) the Qualitative Analysis Guide of Leuven.ResultsTwenty-four publications were identified for inclusion. Four key ethical considerations emerged from this literature: access to fertility preservation, conscientious objection, decision-making capacity of children and young people, and shared decision-making.ConclusionIn the identified literature, there is consensus that transgender children and young people should not be refused access to fertility preservation services solely due to their gender identity, and that clinicians with conscientious objections to fertility preservation for this group have an obligation to refer on to willing providers. Factors that create ethical complexity in this area of paediatric care include the child’s age, mental health, and parents’ views. (shrink)

Given advances in the science of fertility preservation and the link between fertility choices and wellbeing, it is time to reframe our ethical thinking around fertility preservation procedures for children and young people with cancer. The current framing of fertility preservation as a possible offer may no longer be universally appropriate. There is an increasingly pressing need to discuss the ethics of failing to preserve fertility, particularly for patient groups for whom established techniques exist. I argue that (...) the starting point for deliberating about a particular patient should be a rebuttable presumption that fertility preservation ought to be attempted. Consideration of the harms applicable to that specific patient may then override this presumption. I outline the benefits of attempting fertility preservation; these justify a presumption in favour of the treatment. I then discuss the potential harms associated with fertility preservation procedures, which may justify failing to attempt fertility preservation in an individual patient's particular case. Moving from a framework of offer to one of rebuttable presumption in favour of fertility preservation would have significant implications for medical practice, healthcare organizations and the state.

The aim of this paper is to show that a comprehensive account of the role of representations in science should reconsider some neglected theses of the classical philosophy of science proposed in the first decades of the 20th century. More precisely, it is argued that the accounts of Helmholtz and Hertz may be taken as prototypes of representational accounts in which structure preservation plays an essential role. Following Reichenbach, structure-preserving representations provide a useful device for formulating an up-to-date version (...) of a (relativized) Kantian a priori. An essential feature of modern scientific representations is their mathematical character. That is, representations can be conceived as (partially) structure-preserving maps or functions. This observation suggests an interesting but neglected perspective on the history and philosophy of this concept, namely, that structure-preserving representations are closely related to a priori elements of scientific knowledge. Reichenbach’s early theory of a relativized constitutive but non-apodictic a priori component of scientific knowledge provides a further elaboration of Kantian aspects of scientific representation. To cope with the dynamic aspects of the evolution of scientific knowledge, Cassirer proposed a re-interpretation of the concept of representation that conceived of a particular representation as only one phase in a continuous process determined by pragmatic considerations. Pragmatic aspects of representations are further elaborated in the classical account of C.I. Lewis and the more modern of Hasok Chang. (shrink)

Bradley offers a quick and convincing argument that no Boolean semantic theory for conditionals can validate a very natural principle concerning the relationship between credences and conditionals. We argue that Bradley’s principle, Preservation, is, in fact, invalid; its appeal arises from the validity of a nearby, but distinct, principle, which we call Local Preservation, and which Boolean semantic theories can non-trivially validate.

The advantage of our notion over the others is that RCon ∗ can directly be used to construct models of T 2 j . We apply this by (...) proving preservation theorems for theories of bounded arithmetic of the following well-known kind: The ∀ Π 1 b -separation of bounded arithmetic theories S 2 i from T 2 j is equivalent to the existence of a model of S 2 i which does not have a Δ 0 b -elementary extension to a model of T 2 j . More specific, let M ⊨ Ω 1 nst denote that there is a nonstandard element c in M such that the function n ↦ 2 log c is total in M . Let BLΣ 1 b be the bounded collection schema for Σ 1 b -formulas. We obtain the following preservation results: the ∀ Π 1 b -separation of S 2 i from T 2 j is equivalent to the existence of 1. a model of S 2 i +Ω 1 nst which is 1 b -closed w.r.t. T 2 j , 2. a countable model of S 2 i + BLΣ 1 b without weak end extensions to models of T 2 j. (shrink)

In this essay Gillman Payette and Peter Schotch present an account of the key notions of level and forcing in much greater generality than has been managed in any of the early publications. In terms of this level of generality the hoary notion that correct inference is truth-preserving is carefully examined and found wanting. The authors suggest that consistency preservation is a far more natural approach, and one that can, furthermore, characterize an inference relation. But an examination of the (...) usual account of consistency reveals problems that, in general, can be corrected by means of an auxiliary notion of inference (forcing) which relies upon a kind of generalization of consistency, called level. Preservation of the latter is shown to be another of the properties which characterize a logic and forcing is shown to preserve it. The essay ends with a sketch of a result which locates forcing among all possible level-preserving inference relations. (shrink)
