Brazil stands out at the global level for having implemented several policies intending to promote agroecology as a productive paradigm for small-holder farmers. However, the impacts of this process of institutionalization of agroecology still lack research and debates that evaluate the effectiveness of these policies. In this paper, we assess and discuss the impacts of a policy specifically focused on education in agroecology, the support to the establishment of Centers for the Study of Agroecology and Organic Production (NEAs) in more (...) than 150 higher education institutions throughout Brazil. NEAs bring together teachers, researchers, and students who engage in teaching, research, and extension activities in partnerships with peasant farmers, their organizations, and rural extension workers. The hypothesis that guides our analysis is that this support to establish NEAs allowed redistribution of symbolic power in the universities where they were established, supporting agroecology to gain greater legitimacy inside and outside the university field. Based on an in-depth study of four NEAs, performed through participant observation and documentary analysis, the NEAs are evaluated from the perspective of social fields in dispute, first in a university sphere, but also from the perspective of training people in integrative and transdisciplinary thinking that will contest the industrial-corporate food regime. Our findings suggest that the State support to university groups dedicated to the promotion of agroecology has allowed the construction of what we have named agroecological spaces, which symbolically dispute the dominant paradigms in educational institutions, supporting the constitution of material and immaterial agroecological territories.

While the failure of the so-called classical theory of concepts - according to which definitions are the proper way to characterize concepts - is a consensus, metaphysical philosophy of religion still deals with the concept of God in a predominantly definitional way. It thus seems fair to ask: Does this failure imply that a definitional characterization of the concept of God is equally untenable? The first purpose of this paper is to answer this question. I focus on the representational side (...) of the matter. My goal is to analyze the extent to which the most important problems raised against the classical view of concepts affect a definitional-representational approach to the concept of God. The second purpose of the paper is to deepen into these issues, arguing for a pluralistic view of concepts and outlining a hybrid special theory of concepts, called the theory of ideal concepts. The theory is special because it deals with a special sort of concepts that I call ideal concepts; it is hybrid because, in addition to definitions, it uses another structure in the characterization of concepts: ideals. My goal is to argue that when applied to the concept of God and added to a pluralistic view of concepts, this theory can function as a tenable representational theory of the concept of God. (shrink)

O presente artigo fundamenta-se em uma pesquisa bibliográfica com o propósito de instigar debates acerca das estratégias adotadas por instituições e figuras proeminentes na tentativa de obscurecer ou mesmo negar a significativa contribuição das multidões de africanos escravizados que chegaram a estas terras, em larga medida, para o enriquecimento do país. Adicionalmente, baseia-se em uma pesquisa netnográfica com o desígnio de analisar as controvérsias e polêmicas presentes nas plataformas de mídia eletrônica relacionadas às alegações de envolvimento e benefício do Banco (...) do Brasil com o sistema econômico escravista e o tráfico ilegal de escravos. Ademais, o estudo almeja evidenciar que as frequentes tentativas de obliteração ou negação dos episódios de abuso, violência e perseguição contra os africanos e seus descendentes reforçam a percepção de que o reconhecimento e a valorização da contribuição dos negros dependem, em grande medida, de um contínuo exercício de revisão histórica e de um tratamento fiel e apropriado da narrativa histórica.

In this paper I try to answer four basic questions: (1) How the concept of God is to be represented? (2) Are there any logical principles governing it? (3) If so, what kind of logic lies behind them? (4) Can there be a logic of the concept of God? I address them by presenting a formal-logical account to the concept of God. I take it as a methodological desideratum that this should be done within the simplest existing logical formalism. I (...) start with first-order logic (FOL) with identity, and then show that its simplest modal extension (SQML, or the simplest quantified modal logic) is enough for us to formalize a minimally satisfactory theory of the concept of God. I focus exclusively on the monotheistic concept of God. (shrink)

Measurement is a crucial issue in psychological assessment. In this paper a contribution to this task is provided by means of the implementation of an adaptive algorithm for the assessment of depression. More specifically, the Adaptive Testing System for Psychological Disorders (ATS-PD) version of the Qualitative-Quantitative Evaluation of Depressive Symptomatology questionnaire (QuEDS) is introduced. Such implementation refers to the theoretical background of Formal Psychological Assessment (FPA) with respect to both its deterministic and probabilistic issues. Three models (one for each sub-scale (...) of the QuEDS) are fitted on a sample of 383 individuals. The obtained estimates are then used to calibrate the adaptive procedure whose performance is tested in terms of both efficiency and accuracy by means of a simulation study. Results indicate that the ATS-PD version of the QuEDS allows for both obtaining an accurate description of the patient in terms of symptomatology, and reducing the number of items asked by 40%. Further developments of the adaptive procedure are then discussed. (shrink)

Pretendemos mostrar um aspecto pelo qual a leitura que Habermas faz de Rousseau, em Mudança estrutural da esfera pública (1962), é levemente revisada em Direito e democracia (1992). Essa pequena mudança, por sua vez, reestrutura toda a concepção habermasiana da política de Rousseau. We intend to show how Habermas' reading of Rousseau in The Structural Transformation of the Public Sphere (1962) is slightly revised in Between Facts and Norms (1992). This small change restructures the entire Habermasian conception of Rousseau's politics.

Futsal is a sport that presents alternation of high- and low-intensity moments, which lacks investigations regarding the effects of the organization of the training load on biomotor skills. In this sense, this study aims to verify the monitoring of the training load throughout the season and the behavior of biomotor skills in futsal athletes. Twelve futsal athletes from the adult category, who competed in the first division of the Paulista championship, participated in the study. Throughout the season, the internal training (...) load was calculated, through the relationship between volume and the rate of perceived exertion, monotony, and training strain. The training periods were divided into preparatory, competitive, and competitive II for a total of four moments of evaluation: M1: at the beginning of the preparatory period; M2: 50 week, at the end of the preparatory period; M3: 13th week, in the middle of the competitive period; and M4: at the start of the competitive period II. The tests used were: Power of lower limbs: countermovement jump ; Displacement speed, over the 10-meter distance, and Aerobic power by the Carminatti test. The variables analyzed were compared at different moments of evaluation using the two-way ANOVA completed by the Bonferroni test. For monotony, training strain, and ILT, the ANOVA ONE-WAY test was used between the evaluation periods completed by the Bonferroni test. The significance value adopted was p < 0.05. A significant improvement was observed in the power of lower limbs from M1 to M3, from M2 to M3, and from M1 to M4. Aerobic power showed a significant increase from M1 to M3 and from M1 to M4. The ITL showed a difference between competitive I and II in relation to the preparatory period. In conclusion, the proposed training organization was sufficient to improve the power of the lower limbs and the aerobic power. (shrink)

Normative systems have been advocated as an effective tool to regulate interaction in multi-agent systems. The use of deontic operators and the ability to represent defeasible information are known to be two fundamental ingredients to represent and reason about normative systems. In this paper, after introducing a framework that combines standard deontic logic and non-monotonic logic programming, deontic logic programs (DLP), we tackle the fundamental problem of equivalence between normative systems using a deontic extension of David Pearce’s Equilibrium Logic and (...) its monotonic basis, the logic of Here-and-There. We also show how deontic logic programs can be used to represent and reason about normative systems, and establish a strong connection with input-output logic. (shrink)

In this paper, I explore the Presocratic antecedents of the Stoic theory of conflagration and argue that, even though three central theses of this theory have solid antecedents in Presocratic physics, the logical connection between them is a Stoic innovation. I label the Presocratics who hold these theses ‘Anaximandreans’ and include in this group Anaximander himself, Heraclitus and Diogenes of Apollonia, and reveal that Anaximenes, Democritus and Antiphon share with them central meteorological and cosmological assumptions.

Las principales disputas que han tenido lugar en el seno del tomismo contemporáneo han estado marcadas por un fuerte criticismo respecto a la escuela tomista dominicana. Las tesis más discutidas pueden sintetizarse en torno a la comprensión del esse y su énfasis en el conjunto de la filosofía del ser. El dominico canadiense Lawrence Dewan quiso contrarrestar este criticismo equilibrando este énfasis sobre el esse haciendo valer el papel de la forma en el pensamiento de Tomás de Aquino. La forma, (...) que es algo divino en las cosas, no es sólo mera potencia receptiva, sino causa del esse y mediadora del acto creador del ente. En este artículo vamos a estudiar detenidamente las ideas principales del tomismo dewaniano a la luz de los aspectos más originales de la enseñanza del Aquinate, desde una perspectiva crítica.

This article reflects on a significant dimension of the modern history of race in Europe and the world: the processes of mobility of humans as things that accompanied the scientific pursuit of the immutable racial condition of humans. It asks what it might mean to approach racial conceptions as historically embedded in, and shaped by, racial regimes of mobility, that is, the regimes encompassing the practices and apparatuses for the displacement of human bodies as “scientific things” of racial significance for (...) museum and laboratory networks. The article articulates race in Europe as entailed in a history of national, colonial, and postcolonial regimes of mobility. First, it is suggested that the history of race in science can be understood as the history of regimes of mobility of humans as things. It is then discussed how this history of mobility regimes connects with the making of collectives within and beyond Europe—national, imperial, indigenous, and postcolonial. Finally, the article investigates the contemporary expressions of racial regimes of mobility. (shrink)

This article examines the foundation myths of Brazil in the last two centuries, paying particular attention to the relationship between these myths and governmental attitudes toward the hybridity of Northern and Southern ethnic and technoscientific entities. Based upon this examination, the article argues that it is important to consider both the wider temporal frames and the shifts and sedimentations that have formed current foundation myths and shaped their relation to science and technology. Postcolonial science technology studies theories illuminate aspects of (...) this trajectory, but our analysis suggests a more complex scenario that involves internal political dynamics and the work of local intellectuals. We argue that the example of Brazilian social scientists should encourage scholars to go beyond the current focus on breaking the myths of technoscience and undertake mythmaking initiatives with wider societal resonances.

At the beginning of the twenty-first century, South America hosts the world’s greatest di­versity of plants and most animal groups, as well as a variety of environmental movements, involving urban and rural communities. South American academic philosophy, however, has given little consideration to this rich biocultural context. To nourish an emergent regional environmental philosophy three main sources can be identified. First, a variety of ancient and contemporary ecological worldviews and practices offer a rich biocultural array of South American environmental thought (...) that can be disclosed and valued through the work of cultural anthropology, liberation philosophy, liberation pedagogy, liberation theology, ecofeminism, and biocultural conservation. Second, some recent academic environmental philosophy research and teaching teams have been formed in South American universities with the support of the interdisciplinary United Nations Environmental Programme or based on the individual interests of some scattered scholars. Third, social movements have increasingly demanded the incorporation of environmental values into regional policies and decision-making processes. These three sources can foster intercultural, international, and transdisciplinary dialogues to further develop a South American environmental philosophy grounded in its precious biocultural diversity.

La cultura de la sociedad global habitualmente asocia la palabra animal con vertebrados. Paradójicamente, la mayor parte de la diversidad animal está compuesta por pequeños organismos que permanecen invisibles en la cultura global y están sub-representados en la filosofía, las ciencias y la educación. La ciencia del siglo veintiuno ha desentrañado que muchos invertebrados tienen conciencia y capacidad de sentir dolor. Estos descubrimientos apelan a los filósofos de la ética animal a ser más inclusivos y reevaluar la participación de los (...) invertebrados en la comunidad moral. La ciencia también ha advertido sobre la desaparición de los pequeños co-habitantes animales en medio de la sexta extinción masiva. Esta extinción “invisible” apela a los filósofos ambientales a visibilizar a los invertebrados, cuya existencia es preciosa en sí misma y para el funcionamiento de los ecosistemas de los cuales dependen la biodiversidad y las sociedades humanas. Con un enfoque biocultural que integra dimensiones biofísicas y culturales de la biodiversidad, investigo las raíces del chovinismo taxonómico asociado con la sub-representación y la subordinación de los invertebrados en la filosofía y las ciencias modernas. Las malas noticias son que constatamos un marcado vertebratismo en el imaginario animal. Las buenas noticias son que David Hume, Charles Darwin y la ética biocultural proporcionan bases conceptuales para cultivar un aprecio por los pequeños co-habitantes con quienes compartimos nuestros hábitats locales y la biosfera global.

In 2010, American sociologist John Levi Martin asserted that in-depth interviews are inadequate for the study of culture. This sparked a debate in the discipline over the legitimacy of interview methods for researchers of culture and others. Here, we contextualize and contribute to this debate. We review the ideas of Martin and argue that in-depth interviews are in fact valid, well-supported in the field, and useful for investigating cultural phenomena. We build this counter-argument on three angles: epistemological, theoretical and methodological. (...) Given this defense, we also explore how social scientists are implementing innovative ways to complement in-depth interview approaches, such as through social network analysis. En el año 2010, John Levi Martin, un reconocido sociólogo estadounidense dedicó una de sus publicaciones para aseverar que las entrevistas en profundidad eran inadecuadas para estudiar fenómenos culturales. Esto desató un debate en la disciplina respecto a la legitimidad de los métodos basados en entrevistas para aquellos investigadores estudiosos de la sociología de la cultura u otras áreas similares. En este trabajo, contextualizamos y contribuimos a este debate. Revisamos las ideas de Martin y defendimos la idea de que las entrevistas en profundidad realmente son válidas y que existen favorables antecedentes en su aplicación. Por lo tanto sí son necesarias al investigar este tipo de fenómenos. Construimos esta contra-respuesta desde tres ángulos: epistemológico, teórico y metodológico. Haciendo nuestra defensa de este tipo de entrevistas, también damos cuenta de la manera en que científicos sociales implementan formas innovadoras para complementar su función, tal como sucede en el análisis de redes sociales.

In lieu of an abstract, here is a brief excerpt of the content:Future Environmental Philosophies and Their Biocultural Conservation InterfacesRicardo Rozzi (bio)Perhaps it would be better to speak of the future of environmental philosophies, rather than of the future of environmental philosophy. Making explicit a plurality of future trends helps prevent an "Anglo-academic" bias, and emphasizes the need for further developing environmental philosophy into at least two directions: (1) a stronger dialogical interaction with the diverse international constellation of cultural, ethnic, (...) social, political, economic, and ecological dimensions of environmental problems; and (2) a greater integration into the transdisciplinary field of biological and cultural conservation, involving an enhanced actualization of environmental theoretical philosophy into environmental practical philosophy.1. Toward more multi-discursive international environmental philosophiesFurther developing international environmental philosophy can help [End Page 142] to more precisely identify agents and causes of environmental problems, as well as their effects and victims. For instance, the focus on global climate change—and more generally global change, including other processes of rapid environmental transformation such as biotic, linguistic, and cultural homogenization—should not overlook the fact that different human communities, regions, societies, and countries are not equally responsible for such change nor suffer equally from its consequences. For example, today the highest levels of UV radiation fall on areas of Patagonia and the Antarctic Peninsula. These regions are the farthest away from the centers of CFC emissions which generate the stratospheric ozone hole found over the austral portion of the Americas.1 The incorporation of these type of regional distinctions into environmental philosophy provides the opportunity for more precise diagnoses and characterizations of environmental problems than the still-frequent generalizations stated in terms of problems between "humanity and nature."2 Such a lack of specificity is deceptive because it absolves particular responsible agents of environmental problems by referring to all humans or society in general as responsible for them.Secondly, contrasting ecological, social, and political settings generate not only different environmental problems, but also offer a variety of viable options for solving those problems. This is a point that remains frequently overlooked within global environmental agendas. While working in conservation in Latin America, I am continuously surprised by the marked ecological and cultural singularities I find in different localities in which communities have evolved peculiar ways of understanding, valuing, and interacting with their environments.3 On the one hand, environmental philosophy would enrich itself by further incorporating this biocultural diversity. On the other hand, environmental philosophy could provide a valuable contribution to biocultural conservation by better articulating the understanding the reticulate diversity of ecological knowledge and practices that indigenous and non-indigenous old-resident communities have co-evolved with particular ecosystems and historic and cultural settings around the world.Finally, furthering the participation of environmental thinkers of different regions and strengthening environmental philosophy networks could contribute to an international dialogue that would generate more pertinent concepts and propositions by more deeply embracing local [End Page 143] social, historical, political, cultural, linguistic, and ecosystem realities. The dynamic diversity of human ecological worldviews and practices has been addressed by the field of environmental philosophy;4 however, this diversity has still not been sufficiently incorporated as part of a multi-discursive community.* * *2. Incorporating environmental philosophy into the theory and praxis of biocultural conservationDuring the last two decades, a main goal of ecological sciences and biological conservation has been a better integration between human and natural systems. Under currently prevailing scientific approaches, such reconnection has been developed primarily through economic valuation of "ecosystem services" (see, for example, the recent landmark Millennium Ecosystem Assessment).5 Environmental philosophy has had a weak presence as compared to ecological economics in the transdiscipline of biological conservation. This weak presence is mismatched with the numerous calls made by ecologists about the need for environmental ethics, and with the frequent reference to ethical values made by international environmental conventions. For instance, the text of the Convention on Biological Diversity begins with a reference to the intrinsic value of biodiversity but it does not develop this notion at all.6 Similarly, the Millennium Ecosystem Assessment mentions the intrinsic value of biodiversity but does not develop the notion, and ends up justifying the need for its conservation in terms of economic values...

O objetivo deste artigo é analisar o conceito de yoga da Bhagavad-gītā. Cinco concepções de yoga encontradas no texto são descritas: yoga enquanto disciplina ou prática, yoga enquanto disciplina qualificada, yoga enquanto estado mental de equanimidade e renúncia, yoga enquanto estado de união e yoga enquanto poder místico. As relações existentes entre essas concepções são explicitadas e o que podemos chamar de a estrutura do yoga na Bhagavad-gītā é pormenorizada.

he general theme of this paper is the issue of formalization in philosophy; in a more specific way, it deals with the issue of formalization of arguments in analytic philosophy of religion. One argument in particular – Anselm’s Proslogion II ontological argument – and one specific attempt to formalize it – Robert Adams’ formalization found in his paper “The Logical Structure of Anselm’s Arguments”, published in The Philosophical Review in 1971 – are taken as study cases. The purpose of the (...) paper is to critically analyze Adams’ formalization with the intent to shed some light on the following questions: What are the virtues of formally analyzing arguments and the contributions, if any, of such an enterprise to the debate on Anselm’s argument? Which lessons can Adam’s work teach us about the dangers and limitations of formalization? Do these virtues and dangers teach us something about analysis of arguments in general? (shrink)

Animal replaceability is supposed to be a feature of some consequentialist theories, like Utilitarianism. Roughly, an animal is replaceable if it is permissible to kill it because the disvalue thereby caused will be compensated by the value of a new animal’s life. This is specially troubling since the conditions for such compensation seem easily attainable by improved forms of raising and killing animals. Thus, grounding a strong moral status of animals in such theories is somewhat compromised. As is, consequently, their (...) position as an alternative to rights-based theories in animal ethics. Recognising this, some utilitarians tried to disassociate utilitarianism and replaceability. I will here add my voice to this project. However, instead of seeing the culprit in the usual suspects (hedonism, maximisation or the total view), I advance a new proposal. After identifying that the compensating value for a disvaluable action has to be its consequence, I present a restriction on consequences: consequences of sequences of actions cannot be consequences of the isolated actions in the sequences. Given this, the main argument is simple: killing an animal is permissible only if the the value of the new animal’s life is a consequence of the killing; but this value is a consequence of a sequence of actions which involves the killing plus some additional actions; therefore, since, via the restriction, such value is not a consequence of the killing, it is irrelevant to its normative status. I then present two further motivations for the restriction: firstly, it prevents the value of conditional actions from trivially influencing the value of the actions on which they are conditional; secondly, it is useful – even if not a complete solution – to reply other objections to consequentialism: the accordion effect of action and the cluelessness problem. I finally consider a couple of objections. (shrink)

The terms “model” and “model-building” have been used to characterize the field of formal philosophy, to evaluate philosophy’s and philosophical logic’s progress and to define philosophical logic itself. A model is an idealization, in the sense of being a deliberate simplification of something relatively complex in which several important aspects are left aside, but also in the sense of being a view too perfect or excellent, not found in reality, of this thing. Paraconsistent logic is a branch of philosophical logic. (...) It is however not clear how paraconsistent logic can be seen as model-building. What exactly is modeled? In this paper I adopt the perspective of looking at a particular instance of paraconsistent logic—paranormal modal logic—which might be seen as a model of a specific kind of agent: inductive agents. After ntroducing what I call the highlevel and low-level models of inductive agents, I analyze the extent to which the above-mentioned idealizing features of model-building appear in paranormal modal logic and how they affect its philosophical significance.

This paper aims at examining the issue of the role of supreme being theology in non-Abrahamic traditions. According to the dominant view in contemporary philosophy of religion, the philo-sophical project of inferring divine properties from the concept of God as a maximally perfect being, usually called supreme being theology, is an exclusivity of the Abrahamic traditions. In attempting to question this view, I investigate the developments of two key-concepts of Vedāntatradition –the concepts of Brahman (literally, the greatest) and Bhagavān (literally, (...) the possessor of all excellences) –in thethought of three famous vedantins: Śaṅkara, Rāmānuja and Jīva.

Ao mesmo tempo que o malogro da assim chamada teoria clássica dos conceitos - de acordo com a qual definições são a maneira apropriada de caracterizar conceitos - é um consenso, a filosofia metafísica da religião parece ainda lidar com o conceito de Deus de forma predominantemente definicional. Podemos então nos perguntar: Seria esse malogro suficiente para inviabilizar uma caracterização definicional do conceito de Deus? Meu propósito central neste artigo é responder essa pergunta. Adoto uma ênfase representacional. Em outras palavras, (...) desejo analisar até que ponto os problemas mais importantes levantados contra a teoria clássica dos conceitos afetam uma abordagem definicional-representacional do conceito de Deus. Como resultado desse esforço, mostro que as críticas à teoria clássica que ameaçam tal abordagem dependem da pluralidade característica ao contexto inter-religioso, que por si só cria outros problemas.

Neste trabalho, é apresentada uma investigação do que poderia ser chamado de formalização lógica do processo de mudança de teorias devido a anomalias. Por anomalia entende-se um fato observado que faz parte do escopo explanatório de uma teoria, mas que vai de encontro à previsão da mesma. Uma abordagem clássica para restaurar o poder explicativo de uma teoria ameaçada por uma anomalia é a postulação de hipóteses novas e provisórias que, em conjunto com as demais hipóteses auxiliares originais, sejam capazes (...) de resolver a anomalia. Após chegar à algumas conclusões sobre a estrutura de tal processo, propomos um framework lógico multimodal e não-monotônico capaz de representar alguns aspectos-chave dessa faceta importante da dinâmica de teorias científicas. Devido à necessidade de acomodar hipóteses provisórias incompatíveis, esse framework incorpora uma forma fraca de paraconsistência. Como um estudo de caso, analisamos o comportamento anômalo do planeta Urano que ameaçou a mecânica celeste Newtoniana por mais de meio século e ensejou a descoberta do planeta Netuno. -/- In this work, an investigation of what could be called the logical formalization of the theory change process due to anomalies is presented. An anomaly is understood as an observed fact that is part of the explanatory scope of a theory, but that goes against its prediction. A classic approach to restoring the explanatory power of a theory threatened by an anomaly is to postulate new and provisional hypotheses that, together with the other original auxiliary hypotheses, are capable of resolving the anomaly. After reaching some conclusions about the structure of such a process, we propose a multimodal and non-monotonic logical framework capable of representing some key aspects of this important facet of the dynamics of scientific theories. Due to the need to accommodate incompatible provisional hypotheses, this framework incorporates a weak form of paraconsistency. As a case study, we analyze the anomalous behavior of the planet Uranus that threatened Newtonian celestial mechanics for more than half a century and prompted the discovery of the planet Neptune.
