Climate change continues to have recognizable impacts across the globe, as weather patterns shift and impacts accumulate and intensify. In this wider context, urban areas face significant challenges as they attempt to mitigate dynamic changes at the local level — changes such as those caused by intensifying weather events, the disruption of critical supplies, and the deterioration of local ecosystems. One field that could help urban areas address these challenges is conservation biology. However, this paper presents the argument that work (...) in urban contexts may be especially difficult for conservation biologists. In light of current climate change predictions, conservation biology may need to abandon some of its core values in favor of commitments guiding urban ecology. More broadly, this essay aims to reconcile the goals of restoration and conservation, by reconceptualizing what an ecosystem is, in the context of a world threatened by global climate change.

This paper explores the tensions between two disparate approaches to addressing hunger worldwide: Food security and food sovereignty. Food security generally focuses on ensuring that people have economic and physical access to safe and nutritious food, while food sovereignty movements prioritize the right of people and communities to determine their agricultural policies and food cultures. As food sovereignty movements grew out of critiques of food security initiatives, they are often framed as conflicting approaches within the wider literature. This paper explores (...) this tension, arguing that food security is based on a particular model of justice, distributive justice, which limits the sovereignty and autonomy of communities as food producers and consumers. In contrast, food sovereignty movements view food security as a necessary part of food sovereignty, but ultimately insufficient for creating food sustainable communities and limiting wider harms. Rather than viewing food security and food sovereignty as in conflict, we argue that food sovereignty’s justice framework both encompasses and entails justice claims that guide food security projects.

The local food movement is, increasingly, becoming a part of the modern American landscape. However, while it appears that the local food movement is gaining momentum, one could question whether or not this trend is, in fact, politically and socially sustainable. Is local food just another trend that will fade away or is it here to stay? One way to begin addressing this question is to ascertain whether or not it is compatible with liberalism, a set of influential political theories (...) that have shaped and continue to shape our political system. In this paper, I argue that the local food movement is partially compatible with forms of liberalism that accept the limited application of the principle of neutrality, as there are two directions or trends within local food: (1) The systems based direction and (2) the individual focused direction. The systems based direction is not compatible while the individual focused movement is largely compatible with liberalism. I go on to argue that the two directions form a dialectic that increases the political and social sustainability of the movement as a whole. Conceiving of the individual focused and the systems focused directions as in opposition to one another is, itself, a mistake. (shrink)

In this paper, I outline valuable insights that current theorists working in urban environmental ethics can gain from the analysis of nineteenth century urban contexts. Specifically, I argue that an analysis of urban areas during this time reveals two sets of competing metaphysical commitments that, when accepted, shift both the design of urban environments and our relationship with the natural world in these contexts. While one set of metaphysical commitments could help inform current projects in urban environmental ethics, the second (...) “de-animalized” or “cleansed” commitments that influenced the structure of post-nineteenth century urban areas could potentially harm projects in urban environmental ethics. Thus we need to be particularly careful when choosing a metaphysical base for our current urban environmental ethics, as, depending on your specific project, implicitly accepting certain commitments could inadvertently work against the overall goals of the project.

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)

Local food initiatives are steadily becoming a part of contemporary cities around the world and can take on many forms. While some of these initiatives are concerned with providing consumers with farm-fresh produce, a growing portion are concerned with increasing the food sovereignty of marginalized urban communities. This chapter provides an analysis of urban contexts with the aim of identifying conceptual barriers that may act as roadblocks to achieving food sovereignty in cities. Specifically, this paper argues that taken for granted (...) commitments created during the birth of the modern city could act as conceptual barriers for the implementation of food sovereignty programs and that urban food activists and programs that challenge these barriers are helping to achieve the goal of restoring food sovereignty to local communities, no matter their reasons for doing so. At the very least, understanding the complexities of these barriers and how they operate helps to strengthen ties between urban food projects, provides these initiatives with ways to undermine common arguments used to support restrictive ordinances and policies, and illustrates the transformative potential of food sovereignty movements.

Urban residents have the potential to play a key role in helping to facilitate ecological resilience of wilderness areas and ecosystems beyond the city by helping ensure the migration of nonhuman climate refugee populations. Three ethical frameworks related to this issue could determine whether we have an ethical duty to help nonhuman climate refugee populations: ethical individualism, ethical holism, and species ethics. Using each of these frameworks could support the stronger view that policy makers and members of the public have (...) a moral duty to mitigate the impacts of climate induced migration, or the weaker claim that these impacts should be taken into account when making land-use and planning decisions in urban contexts.

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

This paper explores the ethical dimensions of lionfish removal and provides an argument supporting hunting lionfish for consumption. Lionfish are an invasive species found around the world. Their presence has fueled management strategies that predominantly rely on promoting human predation and consumption. We apply rights-based ethics, utilitarian ethics, and ecocentric environmental ethics to the question of whether hunting and eating lionfish is ethical. After applying these perspectives, we argue that, from a utilitarian perspective, lionfish should be culled. Rights-based ethics, on (...) the other hand, are not applicable in this case, while ecocentric environmental ethics would support lionfish removal. (shrink)

The “local food” movement has been growing since at least the mid- twentieth century with the founding of the Rodale Institute. Since then, local food has increasingly become a goal of food systems. Today, books and articles on local food have become commonplace, with popular authors such as Barbara Kingsolver1 and Michael Pollan2 espousing the virtues of eating locally. Additionally, local food initiatives, such as the “farm- tofork,” “Buying Local,” and “Slow Food” have gained a strong international following with clearly (...) visible impacts on the food industry and policy. The numbers of local farmers’ markets, community- supported agriculture projects, and community gardens have been on the rise steadily since 1994. (shrink)

Climate change increasingly impacts the resilience of ecosystems and agricultural production. On the one hand, changing weather patterns negatively affect crop yields and thus global food security. Indeed, we live in an age where more than one billion people are going hungry, and this number is expected to rise as climate-induced change continues to displace communities and thus separate them from their means of food production (Internal Displacement Monitoring Centre 2015). In this context, if one accepts a humancentric ethic, then (...) the focus would be on addressing impacts to agricultural production, and thus food security (Borlaug 1997; Navin 2012). On the other hand, ecological resilience is also being impacted by climate change, as species go extinct or migrate due to fluctuating temperatures and shifting weather patterns. This reduction of resilience negatively impacts ecosystem services and the ability of the natural world to support life (Palmer and Larson 2014; Urban 2015). From an environmental holist perspective, then, one could argue that the ethical path would be to focus on reducing negative impacts to species and/or local ecosystems rather than increasing crop yields. Thus, there appears to be a tension between the prioritization of crop yields and the mitigation of ecosystem impacts. While this tension is well established in the agricultural literature (Kirschenmann 2010; Noll 2018), climatezas lochange exacerbates the situation, as agricultural lands are stressed and climate-induced migrations increase already high demands for foodstuffs, thus bringing the conflict to the forefront (Macdonald et al. 2015; Food and Agriculture Organization of the United Nations 2017a).

While we are currently experiencing a renaissance in philosophical work on agriculture and food ( Barnhill, Budolfson, & Doggett 2016 ; Thompson 2015 ; Kaplan 2012 ), these topics were common sources of discussion throughout the three-thousand-year history of Western thought. For example, the Ancient Greek philosopher Aristotle (2014 ) explored connections between fulfi lling human promise and systems of agriculture ( Thompson & Noll 2015 ) and Hippocrates (1923 ) stressed the importance of cultivating agricultural products provided by (...) nature ( Zwart 2000 ). In order to live a truly human life, Hippocrates argued, one must not passively consume crude food products, as such brutish living leads to terrible suffering. Later, both the Hebrew Bible and Christian Gospels provided clear ethical mandates concerning agricultural practices and the consumption of food. These mandates or ethics needed to be observed regardless of context ( Zwart 2000 ). More recently, Thomas Jefferson added to this literature, as he engaged in agricultural production at his Monticello plantation and wrote extensively on how farming is intimately connected to the political system of democracy ( Thompson & Noll 2015 ). This refl ection on food and agriculture continued into the 20th century, albeit not in the discipline of philosophy. Scientists and agricultural leaders, such as Henry Wallace and Liberty Hyde Bailey, provided important critiques of agricultural practices contemporary to their time. (shrink)

Recently, there has been a concerted effort to shift bioethics’ traditional focus from clinical and research settings to more robustly engage with issues of justice and health equity. This broader bioethics agenda seeks to embed health related issues in wider institutional and cultural contexts and to help develop fair policies. In this paper, we argue that bioethicists who ascribe to the broader bioethics’ agenda could gain valuable insights from the interdisciplinary field of environmental justice and transportation justice, in particular. We (...) then proceed to demonstrate the importance of adopting an intersectional approach to transportation and health. The paper concludes with the argument that intersectional gender inequality is of particular importance when studying both health equity and the unequal distribution of burdens associated with transportation systems in local contexts. This essay is meant to be the beginning of a robust conversation concerning health equity, transportation justice, and intersectional distributions of both benefits and burdens. (shrink)

We explore the ethics of deliberately exposing consenting adults to SARS-CoV-2 to induce immunity to the virus (“DEI” for short). We explain what a responsible DEI program might look like. We explore a consequentialist argument for DEI according to which DEI is a viable harm-reduction strategy. Then we consider a non-consequentialist argument for DEI that draws on the moral significance of consent. Additionally, we consider arguments for the view that DEI is unethical on the grounds that, given that large-scale DEI (...) would be highly likely to result in some severe illnesses and deaths, DEI amounts to a form of killing. Our thesis is that incorporating a DEI program alongside the status-quo “calibrate-the-curve” responses could have significant advantages at the early stages of pandemics. These potential advantages mean that, at a minimum, research into DEI would have been justified early in the COVID-19 pandemic, and that DEI programs should be explored as potential additions to our overall approach to emerging pandemics in the future.

The contours of sustainable systems are defined according to communities’ goals and values. As researchers shift from sustainability-in-the-abstract to sustainability-as-a-concrete-research-challenge, democratic deliberation is essential for ensuring that communities determine what systems ought to be sustained. Discourse analysis of dialogue with Michigan direct marketing farmers suggests eight sustainability values – economic efficiency, community connectedness, stewardship, justice, ecologism, self-reliance, preservationism and health – which informed the practices of these farmers. Whereas common heuristics of sustainability suggest values can be pursued harmoniously, we discuss (...) how this typology reflects the more intricate project of balancing values in tension with one another.

Today the relationship between food and cities is revitalizing urban areas, as food production practices transform locales one block and one neighborhood at a time. The key catalysts of this transformation include the commitment to address the root causes of inequalities within food systems and the desire to increase local control over food systems that have been increasingly industrialized and globalized. These goals, encapsulated by the terms “food justice” and “food sovereignty,” play major roles in guiding local food initiatives in (...) cities today. This study explores how justice-oriented urban agriculture projects transform city contexts in ways that reduce regulatory barriers – barriers that, when left in place, could perpetuate systems of oppression. The study ends with the argument that, by removing regulatory barriers, urban agriculture projects are transforming cityscapes in ways that cultivate justice at the system level. (shrink)

As systems based on opaque Artificial Intelligence (AI) continue to flourish in diverse real-world applications, understanding these black box models has become paramount. In response, Explainable AI (XAI) has emerged as a field of research with practical and ethical benefits across various domains. This paper not only highlights the advancements in XAI and its application in real-world scenarios but also addresses the ongoing challenges within XAI, emphasizing the need for broader perspectives and collaborative efforts. We bring together experts from diverse (...) fields to identify open problems, striving to synchronize research agendas and accelerate XAI in practical applications. By fostering collaborative discussion and interdisciplinary cooperation, we aim to propel XAI forward, contributing to its continued success. Our goal is to put forward a comprehensive proposal for advancing XAI. To achieve this goal, we present a manifesto of 27 open problems categorized into nine categories. These challenges encapsulate the complexities and nuances of XAI and offer a road map for future research. For each problem, we provide promising research directions in the hope of harnessing the collective intelligence of interested stakeholders. (shrink)

Seventy-five years before Niander Wallace brutally kills a newborn replicant in Blade Runner 2049, the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research was formed. Its formation led to the creation of the Belmont Report, which established guidelines for the treatment of human subjects. Wallace uses a scalpel as the instrument of disposal, of the newborn replicant, stabbing her in the womb, thereby ending her life moments after wishing her a happy birthday. The conjunction of (...) 2049 and the Belmont Report leads us to important questions concerning biomedical research, given that replicants are “bioengineered humans.” For example, is the “defective” replicant a human subject, and thus protected by research guidelines, or is she a product or consumer good that did not meet expectations?

Can investing in women’s agriculture increase productivity? This paper argues that it can. We assess climate and gender bias impacts on women’s production in the global South and North and challenge the male model of agricultural development to argue further that women’s farming approaches can be more sustainable. Level-based analysis (global, regional, local) draws on a literature review, including the authors’ published longitudinal field research in Ghana and the United States. Women farmers are shown to be undervalued and to work (...) harder, with fewer resources, for less compensation; gender bias challenges are shared globally while economic disparities differentiate; breaches of distributive, gender, and intergenerational justices as well as compromise of food sovereignty affect women everywhere. We conclude that investing in women’s agriculture needs more than standard approaches of capital and technology investment. Effective ‘investment’ would include systemic interventions into agricultural policy, governance, education, and industry; be directed at men as well as women; and use gender metrics, for example, quotas, budgets, vulnerability and impacts assessments, to generate assessment reports and track gender parity in agriculture. Increasing women’s access, capacity, and productivity cannot succeed without men’s awareness and proactivity. Systemic change can increase productivity and sustainability. (shrink)

Local food projects are steadily becoming a part of contemporary food systems and take on many forms. They are typically analyzed using an ethical, or sociopolitical, lens. Food focused initiatives can be understood as strategies to achieve ethical change in food systems and, as such, ethics play a guiding role. But local food is also a social movement and, thus social and political theories provide unique insights during analysis. This paper begins with the position that ontology should play a more (...) prominent part in the analysis of local food movements, as this lens could provide unique insights into basic commitments guiding such initiatives. The paper presents the argument that ontological analyses are imperative for fully understanding local food movements. It then provides an overview of the justice frameworks and ontological orientations that guide two dominant types of initiatives: Those committed to increasing food security and those committed to food sovereignty. The paper ends with the argument that food sovereignty projects are revolutionary, not only because they challenge us to change industrial food practices, but also because they are built on a radical new political ontology, and co-constitutive food-focused orientation, that forms the foundation for alternative social and political structures.

Since the 1960s, the field of urban studies has blossomed in the United States and the United Kingdom, but philosophers participated very little until recently. We are now seeing Western philosophy both return to its urban roots and develop in new directions that ancient Greek philosophers based in Athens never could have imagined. Of all the disciplines, philosophy is one of the most ancient, and it is rooted in ancient cities; indeed, we could argue that philosophy was demanded by the (...) new political form of the city that developed in Athens. Ancient Athenian philosophers were called to reflect on the meaning of the good city, the good life, and good citizenship... (shrink)

This paper turns to pragmatism for strategies to assist with the timely implementation of conservation efforts, as it provides tools to unfreeze policy decision making so that stakeholders, from farmers to wildlife organizations, can readily address impacts associated with climate induced non-human migration. The first section of this essay introduces readers to the topic of climate induced migration and provides an overview of how agriculture could either inhibit or help facilitate migrating species. The second section then applies Thompson’s analysis of (...) water policy, specifically his triangular structure of libertarianism, utilitarianism, and egalitarianism, to the problem of non-human climate refugees to identify positions that could be taken, as producers, policy makers, and other stakeholders determine if they should adopt strategies to assist migrating species. This analysis ends with the argument that the field of applied ethics, while useful for identifying key policy positions, can provide little insight to stakeholders facing issues associated with climate induced migration. The final section of the paper turns to pragmatism for strategies that could help guide wildlife conservation decisions on the ground. It is the author’s hope that a wide range of readers will find this paper useful, as it brings together work in environmental ethics, wildlife conservation literature, and public policy. (shrink)

During much of the past century, it was widely believed that phonemes--the human speech sounds that constitute words--have no inherent semantic meaning, and that the relationship between a combination of phonemes (a word) and its referent is simply arbitrary. Although recent work has challenged this picture by revealing psychological associations between certain phonemes and particular semantic contents, the precise mechanisms underlying these associations have not been fully elucidated. Here we provide novel evidence that certain phonemes have an inherent, non-arbitrary emotional (...) quality. Moreover, we show that the perceived emotional valence of certain phoneme combinations depends on a specific acoustic feature--namely, the dynamic shift within the phonemes' first two frequency components. These data suggest a phoneme-relevant acoustic property influencing the communication of emotion in humans, and provide further evidence against previously held assumptions regarding the structure of human language. This finding has potential applications for a variety of social, educational, clinical, and marketing contexts. (shrink)

A general class of labeled sequent calculi is investigated, and necessary and sufficient conditions are given for when such a calculus is sound and complete for a finite -valued logic if the labels are interpreted as sets of truth values. Furthermore, it is shown that any finite -valued logic can be given an axiomatization by such a labeled calculus using arbitrary "systems of signs," i.e., of sets of truth values, as labels. The number of labels needed is logarithmic in the (...) number of truth values, and it is shown that this bound is tight. (shrink)

The primary goal of this essay is to provide a comprehensive overview and analysis of the various relations between material artifacts and the embodied mind. A secondary goal of this essay is to identify some of the trends in the design and use of artifacts. First, based on their functional properties, I identify four categories of artifacts co-opted by the embodied mind, namely (1) embodied artifacts, (2) perceptual artifacts, (3) cognitive artifacts, and (4) affective artifacts. These categories can overlap and (...) so some artifacts are members of more than one category. I also identify some of the techniques (or skills) we use when interacting with artifacts. Identifying these categories of artifacts and techniques allows us to map the landscape of relations between embodied minds and the artifactual world. Second, having identified categories of artifacts and techniques, this essay then outlines some of the trends in the design and use of artifacts, focussing on neuroprosthetics, brain-computer interfaces, and personalisation algorithms nudging their users towards particular epistemic paths of information consumption.

The COVID-19 pandemic prompted immense work on the investigation of the SARS-CoV-2 virus. Rapid, accurate, and consistent interpretation of generated data is thereby of fundamental concern. Ontologies––structured, controlled, vocabularies––are designed to support consistency of interpretation, and thereby to prevent the development of data silos. This paper describes how ontologies are serving this purpose in the COVID-19 research domain, by following principles of the Open Biological and Biomedical Ontology (OBO) Foundry and by reusing existing ontologies such as the Infectious Disease Ontology (...) (IDO) Core, which provides terminological content common to investigations of all infectious diseases. We report here on the development of an IDO extension, the Virus Infectious Disease Ontology (VIDO), a reference ontology covering viral infectious diseases. We motivate term and definition choices, showcase reuse of terms from existing OBO ontologies, illustrate how ontological decisions were motivated by relevant life science research, and connect VIDO to the Coronavirus Infectious Disease Ontology (CIDO). We next use terms from these ontologies to annotate selections from life science research on SARS-CoV-2, highlighting how ontologies employing a common upper-level vocabulary may be seamlessly interwoven. Finally, we outline future work, including bacteria and fungus infectious disease reference ontologies currently under development, then cite uses of VIDO and CIDO in host-pathogen data analytics, electronic health record annotation, and ontology conflict-resolution projects.

Nomophobia (no-mobile-phone phobia) is the fear and anxiety of being without a mobile phone. This study pioneers the investigation of nomophobia in Afghanistan using the Nomophobia Questionnaire (NMP-Q), addressing a crucial gap in the field. We collected statistical data from 754 undergraduate medical students, comprising men (56.50 %) and women (43.50 %), and analyzed the dimensions of nomophobia. While results revealed that all but two participants were nomophobic, they identified three significant dimensions affecting the level of nomophobia among participants: (a) (...) gender, (b) age, and (c) marital status. The study's contributions are precious, given the peculiarity of Afghan political turmoil, security, and human rights issues, especially for women. For example, the study's data collection was abruptly halted in December 2022 due to the Taliban regime's decision to make it illegal for women to enroll in universities as students. Therefore, while examining the characteristics of nomophobia across societies is imperative, it is also vital to investigate what is true of one society, Afghanistan, at one point in time and space. The study concludes by emphasizing the need to broaden participants' scope in future studies to better understand the prevalence of nomophobia across broader societal contexts and forces. (shrink)

Epistemologists who study credences have a well-developed account of how you should change them when you learn new evidence; that is, when your body of evidence grows. What's more, they boast a diverse range of epistemic and pragmatic arguments that support that account. But they do not have a satisfactory account of when and how you should change your credences when you become aware of possibilities and propositions you have not entertained before; that is, when your awareness grows. In this (...) paper, I consider the arguments for the credal epistemologist's account of how to respond to evidence, and I ask whether they can help us generate an account of how to respond to awareness growth. The results are surprising: the arguments that all support the same norms for responding to evidence growth support a number of different norms when they are applied to awareness growth. Some of these norms seem too weak, others too strong. I ask what we should conclude from this, and argue that our credal response to awareness growth is considerably less rigorously constrained than our credal response to new evidence. (shrink)

Longtermism is the view that the most urgent global priorities, and those to which we should devote the largest portion of our resources, are those that focus on (i) ensuring a long future for humanity, and perhaps sentient or intelligent life more generally, and (ii) improving the quality of the lives that inhabit that long future. While it is by no means the only one, the argument most commonly given for this conclusion is that these interventions have greater expected goodness (...) per unit of resource devoted to them than each of the other available interventions, including those that focus on the health and well-being of the current population. In this paper, I argue that, even if we grant the consequentialist ethics upon which this argument depends, and even if we grant one of the axiologies that are typically paired with that ethics to give the argument, we are not morally required to choose an option that maximises expected utility; indeed, we might not even be permitted to do so. Instead, I will argue, if the argument's consequentialism is correct, we should choose using a decision theory that is sensitive to risk, and allows us to give greater weight to worse-case outcomes than expected utility theory does. And, I will show, such decision theories do not always recommend longtermist interventions. Indeed, sometimes, they recommend exactly the opposite: sometimes, they recommend hastening human extinction. Many, though not all, will take this as a reductio of the consequentialism or the axiology of the argument. I remain agnostic on the conclusion we should draw. (shrink)

Fourteen philosophers share their experience teaching Peirce to undergraduates in a variety of settings and a variety of courses.

We provide a philosophical reconstruction and analysis of the debate on the scientific status of cosmic inflation that has played out in recent years. In a series of critical papers, Ijjas et al. have questioned the scientificality of the current views on cosmic inflation. Proponents of cosmic inflation have in turn defended the scientific credentials of their approach. We argue that, while this defense, narrowly construed, is successful against Ijjas et al., the latter's reasoning does point to a significant epistemic (...) issue that arises with respect to inflation. A broadening of the concept of theory assessment is needed to address that issue in an adequate way. (shrink)

The literature on the history of electricity production have studied the evolution of electricity in both developed and developing countries and its impact on their economies. Some have laid foundations upon which other works are carried out. A close examination of historiography and multidisciplinary research on electricity production in Ghana shows that more efforts are required to improve the electric power landscape in Ghana. From the colonial era, the increasing demand for electricity has been the biggest challenge plaguing the energy (...) sector. Respective governments have made significant strides in ensuring reliable and universal access to electricity throughout Ghana, yet such efforts have been accompanied by different levels of challenges. The study uses a qualitative and exploratory research approach to trace the activities that helped, in many other ways to the creation of a sustainable electric power provision to household and industry in Ghana, particularly in two of Ghana’s cities; Accra and Kumasi, within the period 1900 to the1960s. The work focused mainly on archival sources in its quest to arrive at how indigenous Ghanaians provided power for industrial activities and for household purposes. Results from the study show that local and cottage industries relied predominantly on wood, fuel, and biomass for their operations even before the introduction of the more sophisticated means of power generation. Also, the study revealed that in finding solutions to the challenges of electricity production, policymakers have focused more on current issues with little or no effort to trace the historical foundation of electricity production. This notwithstanding, the little efforts that have been made examined the history of energy production, with a limited focus on the immediate post-independence era. (shrink)

In a series of papers over the past twenty years, and in a new book, Igor Douven has argued that Bayesians are too quick to reject versions of inference to the best explanation that cannot be accommodated within their framework. In this paper, I survey their worries and attempt to answer them using a series of pragmatic and purely epistemic arguments that I take to show that Bayes’ Rule really is the only rational way to respond to your evidence.

How much does rationality constrain what we should believe on the basis of our evidence? According to this book, not very much. For most people and most bodies of evidence, there is a wide range of beliefs that rationality permits them to have in response to that evidence. The argument, which takes inspiration from William James' ideas in 'The Will to Believe', proceeds from two premises. The first is a theory about the basis of epistemic rationality. It's called epistemic utility (...) theory, and it says that what it is epistemically rational for you to believe is what it would be rational for you to choose if you were given the chance to pick your beliefs and, when picking them, you were to care only about their epistemic value. So, to say which beliefs are permitted, we must say how to measure epistemic value, and which decision rule to use when picking your beliefs. The second premise is a claim about attitudes to epistemic risk, and it says that rationality permits many different such attitudes. These attitudes can show up in epistemic utility theory in two ways: in the way you measure epistemic value; and in the decision rule you use to pick beliefs. This book explores the latter. The result is permissivism about epistemic rationality: different attitudes to epistemic risk lead to different choices of prior beliefs; given most bodies of evidence, different priors lead to different posteriors; and even once we fix your attitudes to epistemic risk, if they are at all risk-inclined, there is a range of different priors and therefore different posteriors they permit.

Conservative assumptions in medical ethics risk immense harms during a pandemic. Public health institutions and public discourse alike have repeatedly privileged inaction over aggressive medical interventions to address the pandemic, perversely increasing population-wide risks while claiming to be guided by ‘caution’. This puzzling disconnect between rhetoric and reality is suggestive of an underlying philosophical confusion. In this paper, I argue that we have been misled by status quo bias—exaggerating the moral significance of the risks inherent in medical interventions, while systematically (...) neglecting the risks inherent in the status quo prospect of an out-of-control pandemic. By coming to appreciate the possibility and significance of status quo risk, we will be better prepared to respond appropriately when the next pandemic strikes. (shrink)

When is it legitimate for a government to ‘nudge’ its citizens, in the sense described by Thaler and Sunstein (2008)? In their original work on the topic, Thaler and Sunstein developed the _‘as judged by themselves’ (or AJBT) test_ to answer this question (Thaler and Sunstein 2008, p. 5). In a recent paper, Paul and Sunstein (2019) raised a concern about this test: it often seems to give the wrong answer in cases in which we are nudged to make a (...) decision that leads to what Paul calls a _personally transformative experience_, that is, one that results in our values changing (Paul 2014). In those cases, the nudgee will judge the nudge to be legitimate after it has taken place, but only because their values have changed as a result of the nudge. In this paper, I take up the challenge of finding an alternative test. I draw on my _aggregate utility account_ of how to choose in the face of what Ullmann-Margalit (2006) calls _big decisions_, that is, decisions that lead to these personally transformative experiences (Pettigrew 2019, Chapters 6 and 7).

The main goal of this paper is to investigate whether humans are unique in using tools and artifacts. Non-human animals exhibit some impressive instances of tool and artifact-use. Chimpanzees use sticks to get termites out of a mound, beavers build dams, birds make nests, spiders create webs, bowerbirds make bowers to impress potential mates, etc. There is no doubt that some animals modify and use objects in clever and sophisticated ways. But how does this relate to the way in which (...) humans make and use objects to achieve their goals? To answer this question, this paper first presents a taxonomy of artifacts, identifying four overlapping categories, namely embodied, perceptual, cognitive, and affective artifacts. It then discusses definitions of animal tool-use, arguing that we need a more liberal approach, one that goes beyond the use of tools that are embedded in occurrent perception-action cycles. This paper ends by analysing how instances of animal tool and artifact-use can be classified according to the four identified categories, concluding that some animals use embodied, perceptual, cognitive, and affective artifacts. In this sense, humans are thus not unique in the kinds of tools and artifacts we use. What is unique, however, is our unprecedented flexibility and openness to deeply incorporate a large variety of complex tools and artifacts into our embodied, perceptual, cognitive, and affective systems.

This essay outlines one way to conceptualise the relation between cultural identity, collective memory, and artifacts. It starts by characterising the notion of cultural identity as our membership to cultural groups and briefly explores the relation between cultural and narrative identity (section 2). Next, it presents how human memory is conceptualised on an individual and collective level (section 3) and then distinguishes between small-scale and large-scale collective memory (section 4). Having described cultural identity and collective memory, it argues that cultural (...) identity is materialised in the environment when we retrieve and construct collective memories by integrating information from our biological memory with information in artifacts or in other people’s embodied brains (section 5). This essay ends with analysing how materialised cultural identities are constructed by using a niche construction approach from evolutionary biology (section 6). (shrink)

In the first half of this paper, I argue that group belief ascriptions are highly ambiguous. What's more, in many cases, neither the available contextual factors nor known pragmatic considerations are sufficient to allow the audience to identify which of the many possible meanings is intended. In the second half, I argue that this ambiguity often has bad consequences when a group belief ascription is heard and taken as testimony. And indeed it has these consequences even when the ascription is (...) true on the speaker's intended interpretation, when the speaker does not intend to mislead and indeed intends to cooperatively inform, and when the audience incorporates the evidence from the testimony as they should. I conclude by arguing that these consequences should lead us to stop using such ascriptions. (shrink)

How should a machine intelligence perform unsupervised structure discovery over streams of sensory input? One approach to this problem is to cast it as an apperception task [1]. Here, the task is to construct an explicit interpretable theory that both explains the sensory sequence and also satisfies a set of unity conditions, designed to ensure that the constituents of the theory are connected in a relational structure. However, the original formulation of the apperception task had one fundamental limitation: it assumed (...) the raw sensory input had already been parsed using a set of discrete categories, so that all the system had to do was receive this already-digested symbolic input, and make sense of it. But what if we don't have access to pre-parsed input? What if our sensory sequence is raw unprocessed information? The central contribution of this paper is a neuro-symbolic framework for distilling interpretable theories out of streams of raw, unprocessed sensory experience. First, we extend the definition of the apperception task to include ambiguous (but still symbolic) input: sequences of sets of disjunctions. Next, we use a neural network to map raw sensory input to disjunctive input. Our binary neural network is encoded as a logic program, so the weights of the network and the rules of the theory can be solved jointly as a single SAT problem. This way, we are able to jointly learn how to perceive (mapping raw sensory information to concepts) and apperceive (combining concepts into declarative rules). (shrink)

Orthodox semantics for natural language modals give rise to two puzzles for their interactions with disjunction: Ross’s puzzle and the puzzle of free choice permission. It is widely assumed that each puzzle can be explained in terms of the licensing of ‘Diversity’ inferences: from the truth of a possibility or necessity modal with an embedded disjunction, hearers infer that each disjunct is compatible with the relevant set of worlds. I argue that Diversity inferences are too weak to explain the full (...) range of data. Instead, I argue, modals with embedded disjunctions license ‘Independence’ inferences: from the truth of a modal with an embedded disjunction, hearers infer that each disjunct is an independent alternative among the relevant set of worlds. I then develop a bilateral inquisitive semantics for modals that predicts the validity of these Independence inferences. My account vindicates common intuitions about both Ross’s puzzle and the puzzle of free choice permission, and explains the full range of data. (shrink)

What we value, like, endorse, want, and prefer changes over the course of our lives. Richard Pettigrew presents a theory of rational decision making for agents who recognise that their values will change over time and whose decisions will affect those future times.

Angell's logic of analytic containment AC has been shown to be characterized by a 9-valued matrix NC by Ferguson, and by a 16-valued matrix by Fine. We show that the former is the image of a surjective homomorphism from the latter, i.e., an epimorphic image. The epimorphism was found with the help of MUltlog, which also provides a tableau calculus for NC extended by quantifiers that generalize conjunction and disjunction.

This paper clarifies the usage of Albert Hirschman’s categories of market behaviour as of exit and voice in debates about workplace democracy by taking seriously his critique of the neoclassical analysis of competition. Pro-market liberals are generally hostile to the idea of workplace democracy and tend to favour top-down hierarchies as a way of organising labour. This hostility is generally inspired by the neoclassical analysis of exploitation and efficiency, which leads them to defend distributions achieved through exit-based competitive equilibria. Following (...) Hirschman, I propose to consider a hypothetical alternative: a democratic equilibrium, reached through the use of voice. I show that it would present the same appealing characteristics than its competitive counterpart while also accounting for the non-ideal conditions in which markets operate. Support for free markets should entail support for workplace democracy minimally understood as a strengthening of voice. (shrink)

Many consider Nozick’s “utility monster”—a being more efficient than ordinary people at converting resources into wellbeing, with no upper limit—to constitute a damning counterexample to utilitarianism. But our intuitions may be reversed by considering a variation in which the utility monster starts from a baseline status of massive suffering. This suggests a rethinking of the force of the original objection.

This paper describes an attempt to repurpose Kant’s a priori psychology as the architectural blueprint for a machine learning system. First, it describes the conditions that must be satisfied for the agent to achieve unity of experience: the intuitions must be connected, via binary relations, so as to satisfy various unity conditions. Second, it shows how the categories are derived within this model: the categories are pure unary predicates that are derived from the pure binary relations. Third, I describe how (...) Kant’s cognitive architecture has been implemented in a computer system (the Apperception Engine) and show in detail what it is like for the system to construct a unified experience from a sequence of raw sensory input.

The debate over persistence currently involves three competing theories—one three-dimensionalist theory called “endurantism” and two four-dimensionalist theories called “perdurantism” and “exdurantism.” This inner debate between the latter two persistence theories is what I aim to clarify, and ultimately, I argue that perdurantism is superior to exdurantism because exdurantism is too extravagant in counting ordinary objects in the world. Extravagant for the reason that objects in their entirety are bound to their momentary stages, and there is practically an interminable number of (...) these stages, which is not reasonable when counting in the ordinary world.

When is a belief justified? There are three families of arguments we typically use to support different accounts of justification: arguments from our intuitive responses to vignettes that involve the concept; arguments from the theoretical role we would like the concept to play in epistemology; and arguments from the practical, moral, and political uses to which we wish to put the concept. I focus particularly on the third sort, and specifically on arguments of this sort offered by Clayton Littlejohn in (...) Justification and the Truth-Connection and Amia Srinivasan in ‘Radical Externalism’ : 395–431, 2018) in favour of externalism. I counter Srinivasan’s argument in two ways: first, I show that the internalist’s concept of justification might figure just as easily in the sorts of structural explanation Srinivasan thinks our political goals require us to give; and I argue that the internalist’s concept is needed for a particular political task, namely, to help us build more effective defences against what I call epistemic weapons. I conclude that we should adopt an Alstonian pluralism about the concept of justification. (shrink)

In a study drawing from both evolutionary biology and the social sciences, evidence and argument is assembled in support of the comprehensive appli- cation of selfish gene theory to the human population. With a focus on genes giving rise to characteristically-human cooperation (“cooperative genes”) in- volving language and theory of mind, one may situate a whole range of pat- terned behaviour—including celibacy and even slavery—otherwise seeming to present insuperable difficulties. Crucially, the behaviour which tends to propa- gate the cooperative genes (...) may be “at cost” to the genes of some who may be party to the cooperation itself. Explanatory insights are provided by Trivers’ parent-offspring conflict theory, Lack’s principle, and Hamilton’s kin selec- tion mechanism. A primary observation is that cooperation using language and theory of mind is itself interdependent with full human conceptualization of a world of objects and of themselves as embodied beings. Human capaci- ties inhering in, or arising out of, the ability to cooperate are also responsible for a vitally important long-term process, the domestication of animals and p- lants. The approach illuminates the difference between animal and human sexual behaviour, and the emergence of kinship systems. Again, recent pat- terns of population growth become much more explicable. It is argued that the gene is the single controlling replicator; the notion of the meme as a sec- ond independent replicator is flawed. (shrink)
