Three recent research reports by Topping and Trickey, by Fair and colleagues, and by Gorard, Siddiqui and Huat See have produced data that support the conclusion that a Philosophy for Children program of one-hour-per-week structured discussions has a marked positive impact on students. This article presents data from a follow up study done three years after the completion of the study reported in Fair et al.. The data show that the positive gains in scores on the Cognitive Abilities Test were (...) still present and had not faded after three years. Given the strength of these confirmations of the positive durable impact of the P4C program of structured discussions and given the relatively low cost of implementing the P4C program, it is recommended that it become a standard part of the school curriculum.

Some bioethicists argue that conscientious objectors in health care should have to justify themselves, just as objectors in the military do. They should have to provide reasons that explain why they should be exempt from offering the services that they find offensive. There are two versions of this view in the literature, each giving different standards of justification. We show these views are each either too permissive (i.e. would result in problematic exemptions based on conscience) or too restrictive (i.e. would (...) produce problematic denials of exemption). We then develop a middle ground position that we believe better combines respect for the conscience of healthcare professionals with concern for the duties that they owe to patients. Our claim, in short, is that insofar as objectors should have to justify themselves, they should have to do it according to the standard that we defend rather than according to the standards that others have developed.

This paper examines the attribution to Eckhart of the unpublished collationes contained in the MS Bernkastel-Kues, Bibliothek des St. Nikolaus-Hospitals 21. Eckhart’s authorship was excluded by Koch, but is plausible from the point of view of the history of the manuscript tradition. The paper announces the discovery of a series of similar collationes in a Lüneburg manuscript of Franciscan origin and highlights, through the edition of the texts relating to Advent, some parallels between both works, probably depending on the use (...) of a common source.

Digital artifacts often fail to perform as expected. It has recently been argued that this should not be analyzed as software malfunctioning. Rather, every case that is not the result of hardware failures would be due to design errors. This claim, which hinges on the notion of ‘implementation’, highlights a potential fundamental difference between software and other technical artifacts. It also implies that software engineers have more extensive responsibilities than creators of other artifacts. After reconstructing the argument, we show that (...) it rests on two presuppositions regarding the nature of software and the activities of its creators, which we call ‘complete control’ and ‘self-containedness’. Software is taken to be a self-contained unit through which the software engineer exerts complete control over a machine’s behavior. These two presuppositions as well as the usage of implementation and strong claims regarding responsibility can be found throughout the literature on software engineering. Still, we argue that the presuppositions are untenable in light of current practices. For one thing, software engineers cannot exert complete control because software has become too complex for any technique to reliably locate every fault in it. For another, the creation and running of software are nowadays heavily mediated processes involving many agential activities. As a result, the performance of digital artifacts may vary, often in undesirable ways, without either hardware failures or design errors. This undermines the conclusion that software cannot malfunction, while also revealing the complications in developing a metaphysical account of software that fits contemporary practices. (shrink)

What is a problem? What is problematic about any problem whatsoever, philosophical or otherwise? As the origin of assertion and apodeiction, the problematic suspends the categories of necessity and contingency, possibility and impossibility. And it is this suspension that is the essence of the problem, which is why it is so suspenseful. But then, how is the problem problematic? Only if what is suspended neither comes to presence, nor simply goes out into absence, that is, if the suspension continues, which (...) continues the problem. But what is problematic about suspension? As a consideration of language shows, the problem of suspension is the problem of implication. If being, for example, is merely implied, neither present nor absent, then it is the suspension of both, at least insofar as it is problematic. And this not only says something about language; rather, it has ontological implications as well — it speaks of being, and the being of anything whatsoever. For if being is implied, if that is the problem of being, it is because being is an implication. Then the being of things like problems is implied as well; or being is in things by implication. But what does it mean for being to be neither presence nor absence, but an implication? It means that being is implied in a way that is problematic — before it is necessary, or even possible. For being’s way of being is characterized by suspension — which has implications for thinking and speaking about being, and about things like problems, even about anything whatsoever. And this has implications for what being implies, namely, unity and time and aspect. (shrink)

Agro-ecological innovations aim at promoting sustainable agricultural practices that have long term benefits. However, farmers rarely adopt beneficial innovations in agro-ecology despite expressing an understanding of the benefits and a desire to do so. It has been argued that the farmers lack sufficient knowledge to implement complex innovations. We believe that in many cases such knowledge is necessary, but is ultimately insufficient for complex innovation adoption. We argue that in addition to knowledge and a desire to adopt an innovation, many (...) farmers require a collaborative relation with an ally. We call this method the Alliance Approach to innovation. This approach is modeled after the therapeutic Alliance Approach at work in cognitive and behavioral sciences. We argue that using the Alliance Approach will not only prove effective in helping farmers adopt complex agro-ecology innovations, but also a better fit for the human centered development of capability approach human development, as it is likely to enhance both the well-being and agency of the farmers.

In this paper, i provide an introduction to development ethics and make some observations about integral human development. i argue that although there is very little dialogue between these two traditions, they have a lot of common ground, and can helpfully inform one another. International development ethics is a largely secular field concerned with ethical reflection on the ends and means of development. i discuss four levels of ethical reflection: meta-ethical, normative, practical, or applied, and personal or integral. The first (...) three of these levels are well established in philosophical ethics. i introduce the fourth with the hope of encouraging more discussion of how individuals engaged in the theory and practice of development ethics ought to navigate the various spheres of their own lives. This last stage of ethical reflection and action can benefit greatly from work done in integral human development. Integral human development is integral in at least two ways: development is not simply economic development, but development the whole person, including social, political, creative, spiritual, etc., and development is the development of every person, whether the person is a marginalize peasant or a powerful élite. i explain why this second way of integration is both less discussed and more radical than the first. Resumen En este artículo, ofrezco una introducción a la ética del desarrollo y hago algunas observaciones sobre el desarrollo humano integral. Sostengo que, aunque hay muy poco diálogo entre estas dos tradiciones, tienen mucho terreno común y pueden ayudarse mutuamente. La ética del desarrollo internacional es un campo ampliamente secular que se ocupa de la reflexión ética sobre los fines y los medios de desarrollo. Discuto cuatro niveles de reflexión ética: meta-ético, normativo, práctico, o aplicado, y personal o integral. Los tres primeros de estos niveles están bien establecidos en la ética filosófica. Presento el cuarto con la esperanza de fomentar una mayor discusión sobre cómo los individuos involucrados en la teoría y la práctica de la ética del desarrollo deben navegar por las diversas esferas de sus propias vidas. Esta última etapa de reflexión y acción ética puede beneficiarse enormemente del trabajo realizado en el desarrollo humano integral. El desarrollo humano integral es integral en al menos dos maneras: el desarrollo no es simplemente desarrollo económico, sino el desarrollo de toda la persona, incluyendo social político, creativo, espiritual etc., y el desarrollo es el desarrollo de cada persona, sea la persona un campesino marginado o una de la ponderosa elite. Explico por qué esta segunda forma de integración es menos discutida y más radical que la primera. (shrink)

Integral human development is a human-centered development perspective that originated from Catholic social teaching. The perspective holds that authentic development is development that makes every person “more human.” Although it is seldom named in the literature, integral human development has had considerable influence on notions of authentic development, and in turn, development ethics. In this short chapter, I provide a brief explanation of the origins and implications of the conceptual foundations of integral human development both within and beyond the Catholic (...) Church. I argue that integral human development offers a truly radical participatory approach to human development. I briefly raise and respond to some concerns about agency, civic liberty, and integral human development’s connection to the Catholic Church. I conclude with a short explanation of integral human development in practice. (shrink)

In this opinionated review, I draw attention to some of the contributions reinforcement learning can make to questions in the philosophy of mind. In particular, I highlight reinforcement learning's foundational emphasis on the role of reward in agent learning, and canvass two ways in which the framework may advance our understanding of perception and motivation.

An agent exercises instrumental rationality to the degree that she adopts appropriate means to achieving her ends. Adopting appropriate means to achieving one’s ends can, in turn, involve overcoming one’s strongest desires, that is, it can involve exercising synchronic self-control. However, contra prominent approaches, I deny that synchronic self-control is possible. Specifically, I draw on computational models and empirical evidence from cognitive neuroscience to describe a naturalistic, multi-system model of the mind. On this model, synchronic self-control is impossible. Must we, (...) then, give up on a meaningful conception of instrumental rationality? No. A multi-system view still permits something like synchronic self-control: an agent can control her very strong desires. Adopting a multi-system model of the mind thus places limitations on our conceptions of instrumental rationality, without requiring that we abandon the notion altogether. (shrink)

This special issue marks the culmination of Hypatia's twenty-fifth anniversary year. We kicked off the celebration of Hypatia's quarter century as an autonomous journal with a conference, "Feminist Legacies/Feminist Futures," which drew close to 150 attendees—a capacity crowd, and more than twice what we'd expected in the planning stages! The conference provided an opportunity to reflect on how Hypatia came to be and how it has shaped feminist philosophy.

Hohwy et al.’s (2008) model of binocular rivalry (BR) is taken as a classic illustration of predictive coding’s explanatory power. I revisit the account and show that it cannot explain the role of reward in BR. I then consider a more recent version of Bayesian model averaging, which recasts the role of reward in (BR) in terms of optimism bias. If we accept this account, however, then we must reconsider our conception of perception. On this latter view, I argue, organisms (...) engage in what amounts to policy-driven, motivated perception.

Capability approach pioneers Amartya Sen and Martha Nussbaum both recognize empowerment as an important aspect of human development. They seem to disagree, however, about how empowerment should be represented within the capability approach (CA). This essay is concerned with the analysis of the foundational concepts at work within Sen and Nussbaum’s CAs. Part One concerns the key concepts of empowerment at work in Sen’s CA and has three goals. 1) Clarify Sen’s various empowerment concepts. 2) Argue that Sen’s concept of (...) Realize Agency Success is flawed. 3) Make clear that empowerment in Sen’s approach can be helpfully understood in terms of agency and capability set expansion. Part Two considers Nussbaum’s CA and the debate over whether it can account for empowerment. I conclude that not only can Nussbaum’s CA account for empowerment, but that the role of empowerment in both Sen’s and Nussbaum’s CAs can be understood in terms of agency and capability set expansion. In other words, Sen and Nussbaum actually agree about empowerment at the foundational level. (shrink)

Are slurring statements, when applied to members of the slurred group, true, false, or a little bit of both? Intuitions are mixed. And investigating more truth-value judgments is unlikely to cure the stalemate we find ourselves in. Truth-value judgments are just not up to the task. In their place, I propose we look to judgments of lying instead. This change in focus provides a new and better tool for understanding the complex semantics and pragmatics of slurs. As I argue, it (...) also suggests that slurring statements encode, conventionally implicate and presuppose the same information as statements with the slur's neutral counterpart. I then briefly apply this style of argument to the semantics and pragmatics of evaluative language more generally. (shrink)

I propose that the successes and contributions of reinforcement learning urge us to see the mind in a new light, namely, to recognise that the mind is fundamentally evaluative in nature.

International development theorists and practitioners agree that human empowerment is a necessary part of good development. This agreement is encouraging because attention and resources are being directed towards the important goal of empowering the oppressed. It is problematic because the agreement is relatively superficial and masks some deep and important disagreements about the goals and means of development theory, policy, and practice. Chapters One and Two compare the dominant economic growth approach to development with the capability approach, a relatively new (...) alternative. I determine that the capability approach offers a more complete and therefore, superior concept of empowerment. Chapter Three considers Thomas Pogge’s argument for the conclusion that the praise and attention the capability approach receives cannot be justified. I explain that Pogge’s argument is based on a misunderstanding of crucial aspects of the capability approach, including the important role of empowerment. Chapters Four and Five provide detailed consideration of the role of empowerment within both Amartya Sen’s and Martha Nussbaum’s versions of the capability approach. I conclude that although neither scholar consistently uses the term empowerment, the concept of empowerment – both as agency and as capability-set expansion – plays a robust role on both versions of the approach. Moreover, I make the controversial suggestion that many of the differences between Sen and Nussbaum are more a matter of style than substance. Chapter Six considers the concern that Sen does not do enough to engage the role of institutionalized power in generating inequalities that prevent individuals from being empowered. I conclude that despite valuable contributions, Sen fails to provide a complete account of empowerment issues. However, this is not a fatal flaw. Considering both Sen’s contributions, and the fact that the approach is well suited to accommodate a more complete understanding of institutionalized power and of empowerment for development (for example, Naila Kabeer’s Social Relations Approach), it is clear that Sen and the capability approach have offered valuable steps towards a complete concept of empowerment.

Sam Berstler has recently argued for a fairness-based moral difference between lying and misleading. According to Berstler, the liar, but not the misleader, unfairly free rides on the Lewisian conventions which ground public-language meaning. Although compelling, the pragmatic and metasemantic backdrop within which this moral reason is located allows for the generation of a vicious explanatory circle. Simply, this backdrop entails that no speaker has ever performed an assertion. As I argue, escaping the circle requires rejecting Berstler’s fairness-based reason against (...) lying. The problem is a general one: the wrong of lying cannot be founded on the goods of language. (shrink)

Some of the central questions that have been explored by Latin American and Latinx philosophers are questions of metaphilosophy. "Metaphilosophy" refers to philosophical reflections on the nature of philosophy itself. For example, we might ask: What is the purpose of doing philosophy? How does philosophy compare and contrast with other disciplines, such as science, theology, or literature? And what is the best way of categorizing the different kinds and traditions of philosophy? These are philosophical questions about philosophy as an activity (...) and as a discipline. In this chapter, we discuss some ways that Latin American and Latinx philosophers have addressed these and other metaphilosophical issues. Our focus will be on the following questions: What are the defining characteristics of Latin American philosophy and Latinx philosophy? Do they constitute distinctive traditions of philosophy, and if so, what is especially valuable about these traditions? (shrink)

We argue that the core social being system is unlike other core systems in that it participates in frequent, widespread learning. As a result, the social being system is less constant throughout the lifespan and less informationally encapsulated than other core systems. This learning supports the development of the precursors of bias, but also provides avenues for preempting it.

We chart how neuroscience and philosophy have together advanced our understanding of moral judgment with implications for when it goes well or poorly. The field initially focused on brain areas associated with reason versus emotion in the moral evaluations of sacrificial dilemmas. But new threads of research have studied a wider range of moral evaluations and how they relate to models of brain development and learning. By weaving these threads together, we are developing a better understanding of the neurobiology of (...) moral judgment in adulthood and to some extent in childhood and adolescence. Combined with rigorous evidence from psychology and careful philosophical analysis, neuroscientific evidence can even help shed light on the extent of moral knowledge and on ways to promote healthy moral development.

Abstract: In an era of rapid technological advancements, artificial intelligence (AI) has transformed surveillance systems, enhancing security capabilities across the globe. However, the deployment of AI-driven surveillance raises significant ethical concerns, particularly in balancing the need for security with the protection of individual privacy. This paper explores the ethical challenges posed by AI surveillance, focusing on issues such as data privacy, consent, algorithmic bias, and the potential for mass surveillance. Through a critical analysis of the tension between security and privacy, (...) this paper examines the implications of AI technologies on civil liberties and human rights. It also highlights the importance of establishing clear regulatory frameworks and ethical guidelines to ensure that AI surveillance systems operate within boundaries that respect individual freedoms. In navigating this delicate balance, we propose solutions that prioritize transparency, accountability, and the protection of privacy in the digital age. (shrink)

As biological and biomedical research increasingly reference the environmental context of the biological entities under study, the need for formalisation and standardisation of environment descriptors is growing. The Environment Ontology (ENVO) is a community-led, open project which seeks to provide an ontology for specifying a wide range of environments relevant to multiple life science disciplines and, through an open participation model, to accommodate the terminological requirements of all those needing to annotate data using ontology classes. This paper summarises ENVO’s motivation, (...) content, structure, adoption, and governance approach. (shrink)

This collection brings together fourteen contributions by authors from around the globe. Each of the contributions engages with questions about how local and global bioethical issues are made to be comparable, in the hope of redressing basic needs and demands for justice. These works demonstrate the significant conceptual contributions that can be made through feminists' attention to debates in a range of interrelated fields, especially as they formulate appropriate responses to developments in medical technology, global economics, population shifts, and poverty.

Abstract: As artificial intelligence (AI) technologies become more integrated across various sectors, ethical considerations in their development and application have gained critical importance. This paper delves into the complex ethical landscape of AI, addressing significant challenges such as bias, transparency, privacy, and accountability. It explores how these issues manifest in AI systems and their societal impact, while also evaluating current strategies aimed at mitigating these ethical concerns, including regulatory frameworks, ethical guidelines, and best practices in AI design. Through a comprehensive (...) analysis of these challenges and proposed solutions, this paper seeks to contribute to the ongoing discourse on responsible AI development, emphasizing the need for a balance between technological advancement and ethical integrity.

The scientific community, we hold, often provides society with knowledge—that the HIV virus causes AIDS, that anthropogenic climate change is underway, that the MMR vaccine is safe. Some deny that we have this knowledge, however, and work to undermine it in others. It has been common to refer to such agents as “denialists”. At first glance, then, denialism appears to be a form of skepticism. But while we know that various denialist strategies for suppressing belief are generally effective, little is (...) known about which strategies are most effective. We see this as an important first step toward their remediation. This paper leverages the approximate comparison to various forms of philosophical skepticism to design an experimental test of the efficacy of four broad strategies of denial at suppressing belief in specific scientific claims. Our results suggest that assertive strategies are more effective at suppressing belief than questioning strategies. (shrink)

Ever since Darwin people have worried about the sceptical implications of evolution. If our minds are products of evolution like those of other animals, why suppose that the beliefs they produce are true, rather than merely useful? We consider this problem for beliefs in three different domains: religion, morality, and commonsense and scientific claims about matters of empirical fact. We identify replies to evolutionary scepticism that work in some domains but not in others. One reply is that evolution can be (...) expected to design systems that produce true beliefs in some domain. This reply works for commonsense beliefs and can be extended to scientific beliefs. But it does not work for moral or religious beliefs. An alternative reply which has been used defend moral beliefs is that their truth does not consist in their tracking some external state of affairs. Whether or not it is successful in the case of moral beliefs, this reply is less plausible for religious beliefs. So religious beliefs emerge as particularly vulnerable to evolutionary debunking.

This chapter discusses the Ganser syndrome and gives a brief account on its clinical features. A significant number of clinicians in Europe continued accepting Ganser's basic postulates that the patients showed significant memory disorder and 'answers towards the question' within the framework of traumatic or reactive hysteria. In elderly patients, Ganser type symptoms may be indicative of the onset of dementia. Ganser syndrome raises the question of the interaction between concepts, ideology and clinical observation. The clinician must be aware that (...) a misdiagnosed case of Ganser-type hysteria may result in lawsuits, unnecessary surgical interventions, inappropriate use of minor and major tranquillizers, and social consequences that may be destabilizing for the patient and family. Positive results in the organic investigation should lead to a firm diagnosis and disconfirmation of Ganser syndrome. Persistent negative results and dramatic improvement should tend to confirm the diagnosis. (shrink)

Wittgenstein’s concepts shed light on the phenomenon of schizophrenia in at least three different ways: with a view to empathy, scientific explanation, or philosophical clarification. I consider two different “positive” wittgensteinian accounts―Campbell’s idea that delusions involve a mechanism of which different framework propositions are parts, Sass’ proposal that the schizophrenic patient can be described as a solipsist, and a Rhodes’ and Gipp’s account, where epistemic aspects of schizophrenia are explained as failures in the ordinary background of certainties. I argue that (...) none of them amounts to empathic-phenomenological understanding, but they provide examples of how philosophical concepts can contribute to scientific explanation, and to philosophical clarification respectively.

Some types of solar radiation management (SRM) research are ethically problematic because they expose persons, animals, and ecosystems to significant risks. In our earlier work, we argued for ethical norms for SRM research based on norms for biomedical research. Biomedical researchers may not conduct research on persons without their consent, but universal consent is impractical for SRM research. We argue that instead of requiring universal consent, ethical norms for SRM research require only political legitimacy in decision-making about global SRM trials. (...) Using Allen Buchanan & Robert Keohane's model of global political legitimacy, we examine several existing global institutions as possible analogues for a politically legitimate SRM decision-making body.

A pecuária brasileira tem destaque acentuado quanto a sua participação no produto interno Bruto nacional (PIB), entretanto, dentro da cadeia produtiva das proteínas de origem animal, a ovinocultura ainda se apresenta como uma atividade com pouca expressividade e tecnificação frente a outras espécies animais domésticas, desta forma seu fomento e próspero desenvolvimento é dependente de inúmeros fatores, sendo que destes o correto manejo reprodutivo de espécies , a escolha de raças autóctones ou do exterior com boa adaptabilidade para serem criadas (...) em regiões de clima tropical e subtropical encontrados no Brasil e a correta seleção quanto a características reprodutivas de matrizes e principalmente de jovens carneiros cujos quais se deseja utilizar como reprodutores em rebanhos que buscam a constante evolução produtiva se faz muito importante. Tal cenário traz à tona a importância da realização de estudos referentes a suplementação de elementos como vitaminas e microminerais, que embora não sejam os maiores constituintes das dietas ofertadas aos animais de interesse zootécnico, exercem grande influência não só no crescimento e desenvolvimento do tecido muscular como também podem estar positivamente correlacionados quanto aos aspectos reprodutivos . O presente trabalho objetivou a avaliação da qualidade seminal e morfometria testicular de carneiros púberes submetidos a suplementação injetável de minerais e vitaminas, sendo utilizados 30 reprodutores divididos em três grupos de dez animais cada, com delineamento dos grupos inteiramente casualizado. Ao primeiro grupo foi administrada suplementação vitamínica e mineral (Grupo VM), no segundo grupo houve apenas suplementação vitamínica (Grupo VIT) e no terceiro grupo a suplementação mineral (Grupo MIN). No presente trabalho buscou-se avaliar os efeitos da aplicação de complexo vitamínico e mineral sobre a qualidade do sêmen ovino, medidas morfométricas testiculares e alteração nas concentrações dos hormônios cortisol e testosterona. Palavras chave: elementos-traço, hormônios, nutracêutico, ovinos, sêmen -/- Brazilian livestock has a strong emphasis in terms of its participation in the Gross National Product (GDP), however, within the production chain of animal proteins, sheep farming still presents itself as an activity with little expressiveness and technology compared to other domestic animal species. in this way its promotion and development depends on the correct methods, which are the reproductive of sheep species, the choice of indigenous or foreign breeds with good adaptability to be created in tropical and subtropical regions found in Brazil and the correct selection of selected animals and selection of products that are very important for the demand for products of constant breeding. This scenario leads to the development of important studies for the supplementation of such vitamins and trace minerals, which, although not the largest components of diets, exert a great influence not only on the growth of muscle tissues but can also be positively correlated with their reproductive aspects. The present evaluation of seminal quality and testicular morphometric of pubertal animals includes an injectable supplement of vitamins and minerals, using 30 sires distributed in three groups of animals each, with a completely random design of the products. The first supplementary group was given the mineral supplement (VM Group) in the second group only vitamin supplementation (VM Group) and the mineral supplementation group (MIN Group).

Phylogeography, a relatively new subdicipline of evolutionary biology that attempts to unify the fields of phylogenetics and population biology in an explicit geographical context, has hosted in recent years a highly polarized debate related to the purported benefits and limitations that qualitative versus quantitative methods might contribute or impose on inferential processes in evolutionary biology. Here we present a friendly, non-technical introduction to the conflicting methods underlying the controversy, and exemplify it with a balanced selection of quotes from the primary (...) biological literature, to invite the philosophy of biology community to pay attention to the elements that have played a primary role in its presumed resolution. We also present the basic features of our own metascientific take on the debate, and point out—as a preliminary step in preparation for upcoming, more detailed treatments—the importance that appeals to authority in fields external to phylogeography per se have played in the current status of this highly visible evolutionary biology dispute.

The empirical part, given the paucity of existing case studies, will be supported in the last survey of the European Social Survey of 2012. By analyzing a set of questions explicit there, we can, indirectly, understand some of the dynamics that characterize these movements. (shrink)

Ontology is one strategy for promoting interoperability of heterogeneous data through consistent tagging. An ontology is a controlled structured vocabulary consisting of general terms (such as “cell” or “image” or “tissue” or “microscope”) that form the basis for such tagging. These terms are designed to represent the types of entities in the domain of reality that the ontology has been devised to capture; the terms are provided with logical defi nitions thereby also supporting reasoning over the tagged data. Aim: This (...) paper provides a survey of the biomedical imaging ontologies that have been developed thus far. It outlines the challenges, particularly faced by ontologies in the fields of histopathological imaging and image analysis, and suggests a strategy for addressing these challenges in the example domain of quantitative histopathology imaging. The ultimate goal is to support the multiscale understanding of disease that comes from using interoperable ontologies to integrate imaging data with clinical and genomics data. (shrink)

There are two foundational, but not fully developed, ideas in paraconsistency, namely, the duality between paraconsistent and intuitionistic paradigms, and the introduction of logical operators that express meta-logical notions in the object language. The aim of this paper is to show how these two ideas can be adequately accomplished by the Logics of Formal Inconsistency (LFIs) and by the Logics of Formal Undeterminedness (LFUs). LFIs recover the validity of the principle of explosion in a paraconsistent scenario, while LFUs recover the (...) validity of the principle of excluded middle in a paracomplete scenario. We introduce definitions of duality between inference rules and connectives that allow comparing rules and connectives that belong to different logics. Two formal systems are studied, the logics mbC and mbD, that display the duality between paraconsistency and paracompleteness as a duality between inference rules added to a common core– in the case studied here, this common core is classical positive propositional logic (CPL + ). The logics mbC and mbD are equipped with recovery operators that restore classical logic for, respectively, consistent and determined propositions. These two logics are then combined obtaining a pair of logics of formal inconsistency and undeterminedness (LFIUs), namely, mbCD and mbCDE. The logic mbCDE exhibits some nice duality properties. Besides, it is simultaneously paraconsistent and paracomplete, and able to recover the principles of excluded middle and explosion at once. The last sections offer an algebraic account for such logics by adapting the swap-structures semantics framework of the LFIs the LFUs. This semantics highlights some subtle aspects of these logics, and allows us to prove decidability by means of finite non-deterministic matrices. (shrink)

Context: The problems that are most in need of interdisciplinary collaboration are “wicked problems,” such as food crises, climate change mitigation, and sustainable development, with many relevant aspects, disagreement on what the problem is, and contradicting solutions. Such complex problems both require and challenge interdisciplinarity. Problem: The conventional methods of interdisciplinary research fall short in the case of wicked problems because they remain first-order science. Our aim is to present workable methods and research designs for doing second-order science in domains (...) where there are many different scientific knowledges on any complex problem. Method: We synthesize and elaborate a framework for second-order science in interdisciplinary research based on a number of earlier publications, experiences from large interdisciplinary research projects, and a perspectivist theory of science. Results: The second-order polyocular framework for interdisciplinary research is characterized by five principles. Second-order science of interdisciplinary research must: 1. draw on the observations of first-order perspectives, 2. address a shared dynamical object, 3. establish a shared problem, 4. rely on first-order perspectives to see themselves as perspectives, and 5. be based on other rules than first-order research. Implications: The perspectivist insights of second-order science provide a new way of understanding interdisciplinary research that leads to new polyocular methods and research designs. It also points to more reflexive ways of dealing with scientific expertise in democratic processes. The main challenge is that this is a paradigmatic shift, which demands that the involved disciplines, at least to some degree, subscribe to a perspectivist view. Constructivist content: Our perspectivist approach to science is based on the second-order cybernetics and systems theories of von Foerster, Maruyama, Maturana & Varela, and Luhmann, coupled with embodied theories of cognition and semiotics as a general theory of meaning from von Uexküll and Peirce.
