By 2050, global livestock production is expected to double—growing faster than any other agricultural sub-sector—with most of this increase taking place in the developing world. As the United Nation’s four-hundred-page report, Livestock’s Long Shadow: Environmental Issues and Options , documents, livestock production is now one of three most significant contributors to environmental problems, leading to increased greenhouse gas emissions, land degradation, water pollution, and increased health problems. The paper draws on the UN report as well as a flurry of other (...) recently published studies in order to demonstrate the effect of intensive livestock production on global warming and on people’s health. The paper’s goal is to outline the problems caused by intensive livestock farming and analyze a number of possible solutions, including legislative changes and stricter regulations, community mobilizing, and consumers choosing to decrease their demand for animal products.

Book review of Martha Nussbaum's book Frontiers of Justice.

In this paper, I assess Martha Nussbaum's application of the capabilities approach to non-human animals for both its philosophical merits and its potential to affect public policy. I argue that there are currently three main philosophical problems with the theory that need further attention. After discussing these problems, I show how focusing on factory farming would enable Nussbaum to demonstrate the philosophical merits of the capabilities approach as well as to suggest more powerful and effectives changes in our public policies.

In this essay, we describe a form of civic engagement for ethics classes in which students identify a community problem and devise a project to address that need. Like traditional service learning, our civic engagement project improves critical thinking and expressive philosophical skills. It is especially effective in meeting pedagogical goals of engaging and expanding student agency and independence while connecting class materials with individual students’ interests. The project can be adapted to a variety of ethics classes and institutional settings. (...) We demonstrate its effectiveness by examining student projects and class evaluations, as well as reporting our own observations, with emphasis on the skills that students develop. We also address details of implementation and answers to theoretical and practical objections. Although students often find this project challenging, they also see it as deeply rewarding; they have been impressed with their own performance and the skills they develop. (shrink)

By drawing on a selection of interviews from the website Engaged Philosophy, this paper highlights the work of philosopher-activists within their classrooms and communities. These philosophers have stepped out of the ivory towers and work directly with media, community and political groups, people in prison; or they encourage their students to engage in activist projects. The variety of approaches presented here shows the many ways philosophically inspired activism can give voice to those who are marginalized, shine a light on injustices, (...) expose the root of social problems, and empower others to seek solutions. This work shows the relevance of philosophy to practical problems and the powerful effects it can have in the world. (shrink)

Tragedy feels disempowering and the confluence of tragedies since the beginning of 2020 can overwhelm one’s sense of agency. This paper describes how we use a civic engagement (CE) project to nurture radical hope for our students. Radical hope involves a desire for a positive outcome surpassing understanding, as well as an activity to strive to achieve that outcome despite its uncertainty. Our CE project asks students to identify ethical issues they care about and respond in a fitting way, questioning (...) the assumption that their efforts do not matter, and imagining creative ways to make a difference that are in their power. We scaffold our CE project in order to nurture hopeful possibilities for students by offering real-world, feasible pathways for addressing systemic problems. -/- . (shrink)

In this volume, Julinna Oxley and Ramona Ilea bring together essays that examine and defend the use of experiential learning activities to teach philosophical terms, concepts, arguments, and practices. Experiential learning emphasizes the importance of student engagement outside the traditional classroom structure. Service learning, studying abroad, engaging in large-scale collaborative projects such as creating blogs, websites and videos, and practically applying knowledge in a reflective, creative and rigorous way are all forms of experiential learning. Taken together, the contributions (...) to Experiential Learning in Philosophy argue that teaching philosophy is about doing philosophy with others. The book is divided into two sections: essays that engage in the philosophical debate about defining and implementing experiential learning, and essays that describe how to integrate experiential learning into the teaching of philosophy. Experiential Learning in Philosophy provides a timely reflection on best practices for teaching philosophical ideals and theories, an examination of the evolution of the discipline of philosophy and its adoption of active modes of learning, and an anticipation of the ways in which pedagogical practices will continue to evolve in the 21 st century.

The use of robots in therapy for children with autism spectrum disorder raises issues concerning the ethical and social acceptability of this technology and, more generally, about human–robot interaction. However, usually philosophical papers on the ethics of human–robot-interaction do not take into account stakeholders’ views; yet it is important to involve stakeholders in order to render the research responsive to concerns within the autism and autism therapy community. To support responsible research and innovation in this field, this paper identifies a (...) range of ethical, social and therapeutic concerns, and presents and discusses the results of an exploratory survey that investigated these issues and explored stakeholders’ expectations about this kind of therapy. We conclude that although in general stakeholders approve of using robots in therapy for children with ASD, it is wise to avoid replacing therapists by robots and to develop and use robots that have what we call supervised autonomy. This is likely to create more trust among stakeholders and improve the quality of the therapy. Moreover, our research suggests that issues concerning the appearance of the robot need to be adequately dealt with by the researchers and therapists. For instance, our survey suggests that zoomorphic robots may be less problematic than robots that look too much like humans. (shrink)

Teachers committed to seeing philosophy as a way of life (PWOL) often focus on assignments that help students develop personal practices, so they experience peace of mind, independence, and a cure from anguish. While we applaud these goals, our work highlights another important aspect of philosophy as a way of life that sometimes is overlooked. We want our students to experience a transformation toward seeing themselves as moral agents, growing in civic virtues, and developing “cosmic consciousness.” To reach this end, (...) we utilize a civic engagement (CE) project that we call the “Experiments in Ethics.” This CE project consists of a series of small, interrelated assignments or “experiments” that help students develop habits and certain civic dispositions. While students complete the experiments throughout the semester, we argue that civically engaged philosophy as a way of life extends beyond the confines of the classroom and the semester as our students cultivate the ability to see themselves as ethical agents capable of making changes in their own lives and the communities in which they live.

This paper aims to study the role of the social robot Probo in providing assistance to a therapist for robot assisted therapy (RAT) with autistic children. Children with autism have difficulties with social interaction and several studies indicate that they show preference toward interaction with objects, such as computers and robots, rather than with humans. In 1991, Carol Gray developed Social Stories, an intervention tool aimed to increase children's social skills. Social stories are short scenarios written or tailored for autistic (...) individuals to help them understand and behave appropriately in social situations. This study shows that, in specific situations, the social performance of autistic children improves when using the robot Probo, as a medium for social story telling, than when a human reader tells the stories. The robot tells Social Stories to teach ASD children how to react in situations like saying “hello“, saying “thank you“ and “sharing toys“. The robot has the capability of expressing emotions and attention via its facial expressions and its gaze. The paper discusses the use of Probo as an added-value therapeutic tool for social story telling and presents the first experimental results.

Currently, there are many advocacy interventions aimed at reducing animal consumption. We report results from a lab (N = 267) and a field experiment (N = 208) exploring whether, and to what extent, some of those educational interventions are effective at shifting attitudes and behavior related to animal consumption. In the lab experiment, participants were randomly assigned to read a philosophical ethics paper, watch an animal advocacy video, read an advocacy pamphlet, or watch a control video. In the field experiment, (...) we measured the impact of college classes with animal ethics content versus college classes without animal ethics content. Using a pretest, post-test matched control group design, humane educational interventions generally made people more knowledgeable about animals used as food and reduced justifications and speciesist attitudes supporting animal consumption. None of the interventions in either experiment had a direct, measurable impact on self-reported animal consumption. These results suggest that while some educational interventions can change beliefs and attitudes about animal consumption, those same interventions have small impacts on animal consumption. (shrink)

Knowledge of human uses of animals is an important, but understudied, aspect of how humans treat animals. We developed a measure of one kind of knowledge of human uses of animals – knowledge of factory farming. Studies 1 (N = 270) and 2 (N = 270) tested an initial battery of objective, true or false statements about factory farming using Item Response Theory. Studies 3 (N = 241) and 4 (N = 278) provided evidence that responses to a 10-item Knowledge (...) of Factory Farming Scale predicted a reduction in consumption of animal products (rs = −.17- −.27) and approval of political actions aimed at factory farming (rs = .2 – .24). Path models from Studies 3 and 4 suggested that different kinds of knowledge uniquely predicted different outcomes. The Knowledge of Factory Farming scale was a unique predictor of approval of political actions concerning factory farmed animals but not animal consumption. Knowledge of Animals Used as Food predicted animal consumption but not political actions concerning farmed animals. These results highlight that different kinds of knowledge can be relevant for different animal related outcomes. (shrink)

Objective: Theory and research suggest that the pursuit of personal goals that do not fit a person's affect-based implicit motives results in impaired emotional well-being, including increased symptoms of depression. The aim of this study was to evaluate an intervention designed to enhance motive-goal congruence and study its impact on well-being. Method: Seventy-four German students (mean age = 22.91, SD = 3.68; 64.9% female) without current psychopathology, randomly allocated to 3 groups: motivational feedback (FB; n = 25; participants learned about (...) the fit between their implicit motives and explicit goals), FB + congruence-enhancement training (CET; n = 22; participants also engaged in exercises to increase the fit between their implicit motives and goals), and a no-intervention control group (n = 27), were administered measures of implicit motives, personal goal commitments, happiness, depressive symptoms, and life satisfaction 3 weeks before (T1) and 6 weeks after (T2) treatment. Results: On two types of congruence measures derived from motive and goal assessments, treated participants showed increases in agentic (power and achievement) congruence, with improvements being most consistent in the FB+CET group. Treated participants also showed a trend-level depressive symptom reduction, but no changes on other well-being measures. Although increases in overall and agentic motivational congruence were associated with increases in affective well-being, treatment-based reduction of depressive symptoms was not mediated by treatment-based agentic congruence changes. Conclusion: These findings document that motivational congruence can be effectively enhanced, that changes in motivational congruence are associated with changes in affective well-being, and they suggest that individuals’ implicit motives should be considered when personal goals are discussed in the therapeutic process.

The functional role of mirror neurons has been assessed in many different ways. They have been regarded, inter alia, as the core mechanism of mind reading, the mechanism of language understanding, the mechanism of imitation. In this paper we will discuss the thesis according to which MNs are a conceptual mechanism. This hypothesis is attractive since it could accommodate in an apparently simple way all the above-mentioned interpretations. We shall take into consideration some reasons suggesting the conceptualist characterization of MNs, (...) as well as some possible replies. We shall figure out how an argument for the conceptualist hypothesis could be deployed, focusing on the notion of off-line processes, which turns out to be the crucial property necessary to ascribe concept possession. Our conclusion will be that, despite of there being some evidence for the conceptualist account, the issue cannot be definitely settled, because there are both experimental shortages and conceptual difficulties. In particular, there are three distinct senses in which MNs can be regarded as a conceptual mechanism, but we shall argue that only one of these interpretations can be defended. (shrink)

The question of why Plato censored poetry in his Republic has bedeviled scholars for centuries. In Exiling the Poets, Ramona A. Naddaff offers a strikingly original interpretation of this ancient quarrel between poetry and philosophy.

The scientific paradigm which I rely upon in the framework of this article is quantum mechanics, whose “cognitive revolution” consisted of replacing the classical principle of separability with the principle of nonseparability or global intercorrelation. According to this intercorrelation, highlighted at the subatomic level, the part cannot be separated from the whole, because every part has a global and instantaneous connection with the whole universe. For this reason the foundation of the world cannot be the part, but the whole, which (...) is therefore logically and ontologically prior to the part, i.e., self-consistent. Consequently, the principle of global intercorrelation elucidates and validates some of the oldest philosophical problems and intuitions about the unity or self-consistency of the world. An example in this sense is the bootstrap theory of American physicist Geoffrey Chew, which presents such striking similarities to the metaphysical system of Leibniz's Monadology that the two intertwine and mirror each other, like twin souls, to the extent that it could be stated that if Chew’s bootstrap theory represents the explanatory physical level of Leibniz’s metaphysics, then, analogously, Leibniz’s Monadology represents the explanatory metaphysical level of Chew’s physics.

Processuality as refusal to “freeze,” “eternize,” and fragment reality is an attempt to deconstruct the I’s main mechanism, which is, as it was named in psychoanalysis, the compulsion of repetition. Through this deceit and illusion fabrication mechanism, the knowing I tries to “freeze”, to “fixate” and to fragment reality, through “catching” it in different images, formulae, dogmas, theories, ideologies, symbols and systems which become just as many “icons” or graven images of reality. This attempt of deconstruction is made from the (...) perspective of a philosophy/vision of process, quite sporadic in the Western space, bringing arguments from the perspective of Henri Bergson and Emil Cioran’s intuitionist philosophy, as well as from that of the new scientific paradigm of quantum mechanics. All these philosophies could be seen as philosophies of process, demanding as it were an understanding of reality in terms of process, and not of result. This understanding of process takes place with the help of intuition, the only one which can grasp, beyond the static, rigid and artificial concepts or categories of the intellect, the movement, “verb” or interior pulsation of things within the framework of an integration process which reveals the unity, non-separability, intercorrelation and mutual interconnectivity of things.

An evaluation was made of theassociations between self-reported healthconscious consumerism, body-mass index (BMI),and consumer beliefs, attitudes, intentions,and behaviors regarding sustainably producedfoods. Self-administered surveys were completedby adult consumers (n = 550) in threemetropolitan Minnesota grocery stores. Selecteddemographic and psychographic differencesbetween health conscious consumers andnon-health conscious consumers were evaluated.Compared to non-health conscious consumers,health conscious consumers were more likely tobe female, older, more educated, higher incomeearners, more active, healthier, and possess ahealthier body mass index. They also held moresupportive beliefs, attitudes, and intentionswith regard (...) to sustainably produced foods. Inconclusion, some consumers are interested insupporting sustainable production practices andtheir support may be linked to improvedpersonal, environmental, and communityhealth. (shrink)

Resumo: A Kehre (viragem) no pensamento de Heidegger foi amplamente discutida e debatida. A introdução da noção de metontologia (Metontologie), em 1927, informou proveitosamente esse debate, uma vez que implica uma preocupação com o domínio ôntico, por parte de Heidegger, que não está presente em trabalhos anteriores. O fato de essa noção desaparecer logo após ser introduzida, porém, desafia sua contribuição para esse debate. Neste artigo, mostra-se que o desaparecimento da metontologia não significa o desaparecimento da preocupação de Heidegger com (...) o ôntico, mas o contrário. Começa-se apresentando a visão de Freeman de uma tensão entre o ôntico e o ontológico, no pensamento de Heidegger, em meados da década de 1920, que resulta na introdução da metontologia, em 1927. Mais tarde, evidencia-se que a explicação de McNeill para o desaparecimento da metontologia, como consequência da visão de Heidegger, de meados dos anos 30, de que a projeção a priori do ser é uma retirada do ser (Entzug des Seins), permite dizer que esse desaparecimento não acarreta uma repentina falta de preocupação de Heidegger com o ôntico. Ao considerar a análise de Heidegger de “o matemático”, em Die Frage nach dem Ding, finalmente, argumenta-se que a metontologia desaparece do pensamento de Heidegger, porque sua dependência da ontologia a impede de explicar sua crescente preocupação com o ôntico, de maneira adequada.

Inconsistent information between an organization’s corporate social responsibility (CSR) commitments and perceived CSR (in-)action is a big challenge for organizations because this is typically associated with perceptions of corporate hypocrisy and related negative stakeholder reactions. However, in contrast to the prevailing corporate hypocrisy literature we argue that inconsistent CSR information does not always correspond to perceptions of corporate hypocrisy; rather, responses depend on individual predispositions in processing CSR-related information. In this study, we investigate how an individual’s moral identity shapes reactions (...) to inconsistent CSR information. The results of our three studies show that individuals who symbolize—i.e., display—their moral identity to the public more than they internalize moral values react less negatively to inconsistent CSR information. We also show that this weakens their anger and willingness to change company behavior. Furthermore, we find that this effect is amplified for extraverted but weakened for neurotic individuals. Our findings underline the importance of individual predispositions in processing CSR information. (shrink)

Jan Patočka’s account of responsibility, as developed in Heretical Essays in the Philosophy of History, is configured through the philosopher’s entire model of history, seen less as a scale of progress, but rather as a rupture. Responsibility is possible only for a very specific form of humanity, centered on history, problematicity and selfdisclosure. This type of historic humanity is in profound contrast with the prehistoric one, focused on “daimonic participation.” Responsibility involves the passage from prehistory to history. Despite the fact (...) that it requires an intense “discipline of the soul,” the passage to responsibility cannot become pure and transparent, which in turn means that history is repeatedly threatened by falling back into prehistory. The positive involved in this assumption is that responsibility is not taken for granted; it is not a matter of following metaphysical principles, but rather a matter of a practical, “heretical” decision of embracing history, with its shaken problematicity, and of resisting the temptation of prehistory.La comprensión de Jan Patočka de la responsabilidad, tal como se desarrolladen Ensayos eréticos de filosofía de la Historia, viene configurada por el modelo completo de Historia, vista más como una ruptura que como una escala de progreso. La responsabilidad es posible sólo para una forma muy concreta de humanidad, centrada en la historia, la problematicidad y el autodescubrimiento. Este tipo de humanidad histórica se halla en profundo contraste con el tipo prehistórico, focalizado sobre la “participación demónica”. La responsabilidad implica el tránsito de la prehistoria a la historia. Pese a requerir una intensa “disciplina del alma”, el tránsito a la responsabilidad no puede tornarse puro y transparente, lo que a su vez significa que la historia está constantemente amenzada por una recaída en la prehistoria. El lado positivo que esta asunción envuelve es que la responsabilidad no se da por garantizada; no es una cuestión de seguir principios metafísicos, sino más bien cuestión de una decisión práctica, “herética”, de abrazar la historia, con su problematicidad conmovida, y de resistir la tentación de la prehistoria.

The Lewisean counterpart theorist– despite not defending a genuinely essentialist view of what is possible, de re, of individuals – generally has a way to make essentialist claims come out as true, in those contexts in which they are endorsed by a committed essentialist. In this paper, I am going to show that the normal system that the Lewisean adopts when she wants to make the essentialist a truth-teller does not work with Kit Fine: his essentialist beliefs, which support his (...) counterexamples to the modal account of essentialism, cannot come out as true, in any contexts whatsoever, under the Lewisean view. After arguing that this represents a genuine problem for Lewis’s theory, I will propose a solution. I will indeed show that the Lewisean has a principled way to account for Fine’s essentialist beliefs, consistently with her own counterpart-theorist reading of them. (shrink)

Written for a series of case studies titled “In the Humanities Classroom,” this contribution describes an undergraduate course on ancient rhetoric at Berkeley, in which Professor Ramona Naddaff was accused by a male student of demeaning women during a lecture and of causing him trauma in the process. He threatened to bring charges against her to campus authorities, claiming the support of fellow students. In her lecture, she had discussed the classical figuration of rhetoric—persuasive speech—as violence and sometimes rape. (...) In a discussion the following week, some students requested the use of “trigger warnings” before the utterance of words like rape. The instructor and her teaching assistant Katharine Wallerstein individually give their views of this disconcerting experience and comment on the difficulties of teaching critical thinking in the current political and cultural climate. They conclude that the language of personal rights and the demand for self-protection tend to come at the expense of teaching and learning alike. (shrink)

Perhaps because groupishness comes so easily to humans, clear operational definitions of the phenomena and justifications for the claim that it is deep‐seated are lacking in much of the literature. Furthermore, the assertion of human groupishness glosses over several important questions including which behaviors, which social boundaries, and which evolutionary processes make us groupish. In this paper I use an evolutionary lens, and cross‐species and cross‐cultural comparative examples to clarify the bases on which such a claim of particular human groupishness (...) can be made. Specifically, if humans are particularly groupish, it is because we produce culturally‐structured social landscapes. This means the cognitive science of groupishness must incorporate the social science of the cultural evolution of group boundaries. (shrink)

In this study, I examine the online discourse of the European refugee crisis on the micro-blogging platform, Twitter. Specifically, I analyze 100 tweets that include #refugeesnotwelcome, and explore how this hashtag is used to express negative feelings, beliefs and ideologies toward refugees and migrants in Europe. Guided by critical discourse studies, I focus on Twitter users’ discursive strategies as well as form and function of semiotic resources and multimodality. Twitter users who include this particular hashtag use a rhetoric of inclusion (...) and exclusion to depict refugees as unwanted, criminal outsiders. These tendencies align with current trends in Europe where nationalist-conservative and xenophobic right-wing groups gain power and establish a socially accepted discourse of racism. (shrink)

Bio-ontologies are essential tools for accessing and analyzing the rapidly growing pool of plant genomic and phenomic data. Ontologies provide structured vocabularies to support consistent aggregation of data and a semantic framework for automated analyses and reasoning. They are a key component of the Semantic Web. This paper provides background on what bio-ontologies are, why they are relevant to botany, and the principles of ontology development. It includes an overview of ontologies and related resources that are relevant to plant science, (...) with a detailed description of the Plant Ontology (PO). We discuss the challenges of building an ontology that covers all green plants (Viridiplantae). Key results: Ontologies can advance plant science in four keys areas: 1. comparative genetics, genomics, phenomics, and development, 2. taxonomy and systematics, 3. semantic applications and 4. education. Conclusions: Bio-ontologies offer a flexible framework for comparative plant biology, based on common botanical understanding. As genomic and phenomic data become available for more species, we anticipate that the annotation of data with ontology terms will become less centralized, while at the same time, the need for cross-species queries will become more common, causing more researchers in plant science to turn to ontologies.

In The Grammar of Society, first published in 2006, Cristina Bicchieri examines social norms, such as fairness, cooperation, and reciprocity, in an effort to understand their nature and dynamics, the expectations that they generate, and how they evolve and change. Drawing on several intellectual traditions and methods, including those of social psychology, experimental economics and evolutionary game theory, Bicchieri provides an integrated account of how social norms emerge, why and when we follow them, and the situations where we are (...) most likely to focus on relevant norms. Examining the existence and survival of inefficient norms, she demonstrates how norms evolve in ways that depend upon the psychological dispositions of the individual and how such dispositions may impair social efficiency. By contrast, she also shows how certain psychological propensities may naturally lead individuals to evolve fairness norms that closely resemble those we follow in most modern societies. (shrink)
