One of the features of John Locke’s moral philosophy is the idea that morality is based on our beliefs concerning the future good. In An Essay Concerning Human Understanding II, xxi, §70, Locke argues that we have to decide between the probability of afterlife and our present temptations. In itself, this kind of decision model is not rare in Early Modern philosophy. Blaise Pascal’s Wager is a famous example of a similar idea of balancing between available options which (...) class='Hi'>Marcelo Dascal has discussed in his important 2005 article “The Balance of Reason”. -/- Leibniz, however, was not always satisfied with this kind of simple balancing. In his commentary to Locke’s Essay, Nouveaux essais sur l’entendement humain, II, xxi, §66, he presented an alternative model which is based on an idea of plural, mutually conflicting inclinations. This kind of model, called as vectorial theory of rational decision by Simo Knuuttila, fits well with Leibniz’s theory of the soul where volitions are formed as a kind of compromise between different inclinations to different goods. -/- I will present these two models and show how they illustrate the practical rationality of Locke and Leibniz and how their moral philosophies differ, although being similar in certain respects. The topics include Leibniz’s criticism of Lockean hedonism and the discussion of akratic behaviour in II, xxi of Essay and Nouveaux essais. (shrink)

Thick terms and concepts, such as honesty and cruelty, are at the heart of a variety of debates in philosophy of language and metaethics. Central to these debates is the question of how the descriptive and evaluative components of thick concepts are related and whether they can be separated from each other. So far, no empirical data on how thick terms are used in ordinary language has been collected to inform these debates. In this paper, we present the first empirical (...) study, designed to investigate whether the evaluative component of thick concepts is communicated as part of the semantic meaning or by means of conversational implicatures. While neither the semantic nor the pragmatic view can fully account for the use of thick terms in ordinary language, our results do favour the semanticist interpretation: the evaluation of a thick concept is only slightly easier to cancel than semantically entailed content. We further discovered a polarity effect, demonstrating that how easily an evaluation can be cancelled depends on whether the thick term is of positive or negative polarity. (shrink)

People have disagreed on the significance of Libet-style experiments for discussions about free will. In what specifically concerns free will in a libertarian sense, some argue that Libet-style experiments pose a threat to its existence by providing support to the claim that decisions are determined by unconscious brain events. Others disagree by claiming that determinism, in a sense that conflicts with libertarian free will, cannot be established by sciences other than fundamental physics. This paper rejects both positions. First, it is (...) argued that neuroscience and psychology could in principle provide support for milder deterministic claims that would also conflict with libertarian free will. Second, it is argued that Libet-style experiments—due to some of their peculiar features, ones that need not be shared by neuroscience as a whole—currently do not support such less demanding deterministic claims. The general result is that neuroscience and psychology could in principle... (shrink)

Multialgebras have been much studied in mathematics and in computer science. In 2016 Carnielli and Coniglio introduced a class of multialgebras called swap structures, as a semantic framework for dealing with several Logics of Formal Inconsistency that cannot be semantically characterized by a single finite matrix. In particular, these LFIs are not algebraizable by the standard tools of abstract algebraic logic. In this paper, the first steps towards a theory of non-deterministic algebraization of logics by swap structures are given. Specifically, (...) a formal study of swap structures for LFIs is developed, by adapting concepts of universal algebra to multialgebras in a suitable way. A decomposition theorem similar to Birkhoff’s representation theorem is obtained for each class of swap structures. Moreover, when applied to the 3-valued algebraizable logics J3 and Ciore, their classes of algebraic models are retrieved, and the swap structures semantics become twist structures semantics. This fact, together with the existence of a functor from the category of Boolean algebras to the category of swap structures for each LFI, suggests that swap structures can be seen as non-deterministic twist structures. This opens new avenues for dealing with non-algebraizable logics by the more general methodology of multialgebraic semantics. (shrink)

Marx says of alienated labor that it does not “belong” to the worker, that it issues in a product that does not belong to her, and that it is unfulfilling, unfree, egoistically motivated, and inhuman. He seems to think, moreover, that the first of these features grounds all the others. All of these features seem quite independent, however: they can come apart; they share no obvious common cause or explanation; and if they often occur together, this seems accidental. It is (...) not clear, then, how Marx’s concept of alienated labor could possess the strong unity that he takes it to have. This article defends a reinterpretation of the concept that explains this unity. The various features of alienated labor, the article argues, all follow from a single, hitherto underappreciated feature of its formal motivational structure: the fact that such labor is motivated not by its product but by an incentive.

The logics of formal inconsistency (LFIs, for short) are paraconsistent logics (that is, logics containing contradictory but non-trivial theories) having a consistency connective which allows to recover the ex falso quodlibet principle in a controlled way. The aim of this paper is considering a novel semantical approach to first-order LFIs based on Tarskian structures defined over swap structures, a special class of multialgebras. The proposed semantical framework generalizes previous aproaches to quantified LFIs presented in the literature. The case of QmbC, (...) the simpler quantified LFI expanding classical logic, will be analyzed in detail. An axiomatic extension of QmbC called QLFI1o is also studied, which is equivalent to the quantified version of da Costa and D'Ottaviano 3-valued logic J3. The semantical structures for this logic turn out to be Tarkian structures based on twist structures. The expansion of QmbC and QLFI1o with a standard equality predicate is also considered. (shrink)

The diversity of interpretations of Aristotle’s treatment of chance and luck springs from an apparent contradiction between the claims that “chance events are for the sake of something” and that “chance events are not for the sake of their outcome.” Chance seems to entail the denial of an end. Yet Aristotle systematically refers it to what is for the sake of an end. This paper suggests that, in order to give an account of chance, a reference to “per accidens causes” (...) is not sufficient. Chance occurs as a parody of teleology; it is a“for-no-purpose” that looks like a purpose. The notion of “irony” is suggested as a way of accounting for a situation that keeps an ambiguity open. The fact that chance is thought of in relation to teleology does not mean that it is “reappropriated” by teleology. Rather,chance reveals a hiatus that betrays the limitation of a language concerned with substances to account for events. (shrink)

The dissertation has two parts, each dealing with a problem, namely: 1) What is the most adequate account of fuzziness -the so-called phenomenon of vagueness?, and 2) what is the most plausible solution to the sorites, or heap paradox? I will try to show that fuzzy properties are those which are gradual, amenable to be possessed in a greater or smaller extent. Acknowledgement of degrees in the instantiation of a property allows for a gradual transition from one opposite to the (...) other, each intermediate stage constituting an overlap in certain proportion of both contraries. Hence, degrees in the possession of a property give rise to simple contradictions. The reason why I have chosen those two questions is that they provide the main philosophical motivation for a particular brand of an infinite valued and paraconsistent logic. I will claim that Classical logic (CL) is not adequate to handle fuzzy situations, and, being deficient, is in need of being expanded to make room for degrees of truth and weak contradictions. One can hardly deny the importance of the debate, since what is ultimately at stake is what the limits of truth, rationality, intelligibility and possibility are. The main disciplines within which the research moves are the philosophy of language, philosophy of logic, and ontology. (shrink)

In the last few decades, the literature on moral responsibility has been increasingly populated by scientific studies. Studies in neuroscience and psychology, in particular, have been claimed to be relevant for discussions about moral responsibility in a number of ways. And at the same time, there is not yet a systematic understanding of the sort of questions a science of moral responsibility is supposed to answer. This paper is an attempt to move toward such an understanding. I discuss three models (...) for framing scientific questions relevant to an investigation of moral responsibility. The favored model—the Enhancement model—proposes that a science of moral responsibility has two descriptive tasks. First, science can describe the causes and effects of the many sorts of responses that constitute the human practices of moral responsibility, such as praise, blame, and punishment. And, second, science can describe how modifications aiming at the improvement of such practices can be achieved. Relatively to the other models to be considered, the Enhancement model is broader in scope and less tied to the traditional philosophical agenda on moral responsibility. (shrink)

The aim of the paper is to analyze the expressive power of the square operator of Łukasiewicz logic: ∗x=x⊙x⁠, where ⊙ is the strong Łukasiewicz conjunction. In particular, we aim at understanding and characterizing those cases in which the square operator is enough to construct a finite MV-chain from a finite totally ordered set endowed with an involutive negation. The first of our main results shows that, indeed, the whole structure of MV-chain can be reconstructed from the involution and the (...) Łukasiewicz square operator if and only if the obtained structure has only trivial subalgebras and, equivalently, if and only if the cardinality of the starting chain is of the form n+1 where n belongs to a class of prime numbers that we fully characterize. Secondly, we axiomatize the algebraizable matrix logic whose semantics is given by the variety generated by a finite totally ordered set endowed with an involutive negation and Łukasiewicz square operator. Finally, we propose an alternative way to account for Łukasiewicz square operator on involutive Gödel chains. In this setting, we show that such an operator can be captured by a rather intuitive set of equations. (shrink)

In a previous paper, I argued that neuroscience and psychology could in principle undermine libertarian free will by providing support for a subset of what I called “statements of local determination.” I also argued that Libet-style experiments have not so far supported statements of that sort. In a commentary to the paper, Adina Roskies and Eddy Nahmias accept the claim about Libet-style experiments, but reject the claim about the possibilities of neuroscience. Here, I explain why I still disagree with their (...) conclusion, despite being sympathetic to a lot of what they say in support of it. (shrink)

In 1988, J. Ivlev proposed some (non-normal) modal systems which are semantically characterized by four-valued non-deterministic matrices in the sense of A. Avron and I. Lev. Swap structures are multialgebras (a.k.a. hyperalgebras) of a special kind, which were introduced in 2016 by W. Carnielli and M. Coniglio in order to give a non-deterministic semantical account for several paraconsistent logics known as logics of formal inconsistency, which are not algebraizable by means of the standard techniques. Each swap structure induces naturally a (...) non-deterministic matrix. The aim of this paper is to obtain a swap structures semantics for some Ivlev-like modal systems proposed in 2015 by M. Coniglio, L. Fariñas del Cerro and N. Peron. Completeness results will be stated by means of the notion of Lindenbaum–Tarski swap structures, which constitute a natural generalization to multialgebras of the concept of Lindenbaum–Tarski algebras.

The master argument posits a metaphysical thesis: Diodorus does away with Aristotle’s dunamis understood as a power simultaneously oriented toward being and non-being and proclaims that possibilities that fail to actualize are simply nothing. My contention is that this claim is not a mere application of Diodorus’ contribution to modal logic. Rather, Diodorus creates an ontologico-temporal concept of possibility and impossibility. Diodorus envisions the future as the past that the future will become. Since what will have been can never be (...) the accomplishment of a possibility that did not obtain, and since the future is destined to become past, any futural possibility that doesn’t actualize is neither futural nor even possible.

From Gadamer's Habilitation thesis, “Plato’s dialectical ethics. Phenomenological Interpretations Relating to the Philebus” (1928), this article seeks to highlight the fundamental lines of Plato’s image, outlined in that author’s first philosophical publication (1931). The confrontation with the themes of ethics and dialectic, in the current state of Platonic studies, indicates that in Plato’s image drawn in the early confrontation with the Philebus, clearly influenced by the phenomenological notion of Dasein, one already finds the fundamental features of what will become Gadamer's (...) philosophical hermeneutics, fully emancipated from Heideggerian tutelage.

Although the controversy between Malthus and Ricardo has long been considered to be an important source for the history of economic thought, it has hardly been the object of a careful study qua controversy, i.e. as a polemical dialogical exchange. We have undertaken to fill this gap, within the framework of a more ambitious project that places controversies at the center of an account of the history of ideas, in science and elsewhere. It is our contention that the dialogical co-text (...) is essential for reconstructing the meaning and the evolution of science. In the present paper we try to substantiate this contention by means of a pragma-rhetorical study of this particular controversy. First, we reconstruct, through an analysis of a chunk of the correspondence, a micro-level of specific moves and countermoves which constitute a sequential structure within which also meta-scientific and meta-controversial considerations play a role. We then move to a macro-level of analysis, looking for recurrent patterns of argumentation. Finally, we draw epistemological conclusions on the nature of rationality and progress as manifested in actual scientific controversies. (shrink)

It is surprisingly difficult to justify private property. Two questions are at stake: (a) a metaphysical and juridical one concerning the nature of property and (b) an ethical one concerning our attitude toward wealth. This issue reached an unprecedented importance during the 12th and 13th centuries as a new moral ideal emerged. This essays analyses the controversy (with emphasis on Bonaventure’s Defense of the Mendicants) by first locating it in relation to the philosophical and theological authorities as well as the (...) Roman law. It argues that the dispute between the defenders of paupertas altissima and their opponents concerns the limit of the law. Gerard of Abbeville and John XXII saw a contradiction in a right to use that would exclude ownership. Yet, what the Franciscans were seeking was use without right. To relate to the world as something that is essentially inappropriable is to seek a form of life (a rule) prior to the law. Centuries after, such a possibility remains to be discovered. (shrink)

Free will skepticism is the view that people never truly deserve to be praised, blamed, or punished for what they do. One challenge free will skeptics face is to explain how criminality could be dealt with given their skepticism. This paper critically examines the prospects of implementing legal changes concerning crime and punishment derived from the free will skeptical views developed by Derk Pereboom and Gregg Caruso. One central aspect of the changes their views require is a concern for reducing (...) the severity of current forms of punishment. The paper considers two strategies for pursuing such a reduction. By taking into account evidence from the psychology of belief in free will and desire to punish, it is argued that a strategy aiming at a reduction of people’s natural desire to punish criminals can be successful if capable of providing alternatives to current forms of punishment satisfying three properties: they must be less harmful than current forms of punishment, more effective in preventing crime, and incompatible with current forms of punishment.

Abstract: The Pull Bayesian Significance Test (FBST) for precise hy- potheses is applied to a Multivariate Normal Structure (MNS) model. In the FBST we compute the evidence against the precise hypothesis. This evi- dence is the probability of the Highest Relative Surprise Set (HRSS) tangent to the sub-manifold (of the parameter space) that defines the null hypothesis. The MNS model we present appears when testing equivalence conditions for genetic expression measurements, using micro-array technology.

This paper focuses on Gilberto Gomes’ work on free will. In a series of contributions that have had a significant impact on the respective literature, Gomes developed a conception about free will and argued that its existence is consistent with recent scientific findings, specially in neuroscience. In this paper, I object to a claim of Gomes about his conception of free will, namely the claim that it is a compatibilist conception. I seek to show that Gomes does not use the (...) term ‘compatibilism’ as it is usual in the contemporary literature on free will, i.e., as the thesis that free will can exist even if determinism is true. Moreover, the conception of free will Gomes proposes actually has an incompatibilist commitment. I argue that, more than a mere terminological point, acknowledging the incompatibilist aspect of Gomes’ view motivates important questions about the details of the view and helps to reveal a limitation of his defense of the existence of free will. [Este artigo tem como tema o trabalho de Gilberto Gomes sobre o livre-arbítrio.

Neste artigo, questiono uma afirmação de Gomes sobre sua concepção sobre o livre-arbítrio, a saber, que se trata de uma concepção compatibilista. Busco mostrar que Gomes não usa o termo ‘compatibilismo’ como é habitual na literatura contemporânea sobre o livre-arbítrio, isto é, como a tese segundo a qual o livre-arbítrio pode existir ainda que o determinismo seja verdadeiro. Ademais, a concepção sobre o livre-arbítrio desenvolvida por Gomes tem, efetivamente, um compromisso incompatibilista. Argumento que, mais do que uma mera elucidação terminológica, reconhecer o elemento incompatibilista presente na proposta de Gomes suscita questões importantes sobre os detalhes da proposta e também ajuda a reconhecer uma limitação de sua defesa da existência do livre-arbítrio.].

Judging a person as morally responsible involves believing that certain responses (such as punishment, reward, or expressions of blame or praise) can be justifiably directed at the person. This paper develops an account of the evolution of moral responsibility judgment that adopts Michael Tomasello’s two-step theory of the evolution of morality and borrows also from Christopher Boehm’s work. The main hypothesis defended is that moral responsibility judgment originally evolved as an adaptation that enabled groups of cooperative individuals to hold free (...) riders responsible more safely by acting in a coordinated way.

Sendo a fenomenologia um modo não-especulativo de pensar, o artigo põe a questão sobre a possibilidade de descrever a metafísica em regime de redução fenomenológica, ou seja, a partir de uma atitude que não pretende discursar sobre o ser enquanto ser, mas sim a partir dos diferentes “modos de aparecer” dos principais “objetos” da metafísica: alma, mundo e Deus. Neste caso, que sentido deverá possuir, para o modo fenomenológico de pensar, o metá, presente na palavra metafísica?

In the current debate in political philosophy, the so-called communitarian thinkers intend to offer an alternative to the dominant liberal thought. The ideal of ethicalcommunity as way of life in society in which intersubjective relationships are ruled by laws conceived as public laws, reintroduces the question of virtue in the scope of social and political life, with the requirement of an ethical style of doing politics.

Resumo: Em décadas recentes, a investigação filosófica sobre a responsabilidade moral e o livre-arbítrio, que por muito tempo foi vista como um empreendimento principalmente teórico, passou a também incluir preocupações de tipo mais prático. Essa mudança é bem ilustrada pela proposta cética desenvolvida por autores como Derk Pereboom e Gregg Caruso. Seus trabalhos não apenas negam que sejamos agentes livres e moralmente responsáveis (em um sentido específico dos termos em questão), mas também defendem reformas na maneira como a responsabilização é (...) efetivada em nossas relações interpessoais e, especialmente, no sistema penal. Este artigo examina as implicações práticas do ceticismo de Pereboom e Caruso, principalmente no que diz respeito à sua implementabilidade. Argumento que o núcleo propriamente cético da proposta é inviável para seres humanos com a psicologia moral que temos, mas que, apesar disso, alguns elementos da proposta são compatíveis com uma proposta não-cética focada no aperfeiçoamento das práticas punitivas. Abstract: In recent decades, the philosophical investigation of moral responsibility and free will, which for a long time was seen as a mostly theoretical enterprise, became also the place of more practically oriented concerns. The skeptical view developed by Derk Pereboom and Gregg Caruso is a good illustration of the change. In their work, they not just deny that we are free and morally responsible agents (in a specific sense of the relevant terms) but also propose the reform of responsibility practices as they figure in our interpersonal relations and, especially, in the criminal justice system. This paper examines the practical implications of Pereboom and Caruso’s skepticism, particularly in what concerns its likelihood of being implemented. I argue that the strictly skeptical core of their proposal is not viable for human beings with a moral psychology like ours, but that some elements are nonetheless consistent with a non-skeptical view focused on the improvement of punitive practices.

In abstract algebraic logic, many systems, such as those paraconsistent logics taking inspiration from da Costa's hierarchy, are not algebraizable by even the broadest standard methodologies, as that of Blok and Pigozzi. However, these logics can be semantically characterized by means of non-deterministic algebraic structures such as Nmatrices, RNmatrices and swap structures. These structures are based on multialgebras, which generalize algebras by allowing the result of an operation to assume a non-empty set of values. This leads to an interest in (...) exploring the foundations of multialgebras applied to the study of logic systems. -/- It is well known from universal algebra that, for every signature Sigma, there exist algebras over Sigma which are absolutely free, meaning that they do not satisfy any identities or, alternatively, satisfy the universal mapping property for the class of Sigma-algebras. Furthermore, once we fix a cardinality of the generating set, they are, up to isomorphisms, unique, and equal to algebras of terms (or propositional formulas, in the context of logic). Equivalently, the forgetful functor, from the category of Sigma-algebras to Set, has a left adjoint. This result does not extend to multialgebras. Not only multialgebras satisfying the universal mapping property do not exist, but the forgetful functor U, from the category of Sigma-multialgebras to Set, does not have a left adjoint. -/- In this paper we generalize, in a natural way, algebras of terms to multialgebras of terms, whose family of submultialgebras enjoys many properties of the former. One example is that, to every pair consisting of a function, from a submultialgebra of a multialgebra of terms to another multialgebra, and a collection of choices (which selects how a homomorphism approaches indeterminacies), there corresponds a unique homomorphism, what resembles the universal mapping property. Another example is that the multialgebras of terms are generated by a set that may be viewed as a strong basis, which we call the ground of the multialgebra. Submultialgebras of multialgebras of terms are what we call weakly free multialgebras. Finally, with these definitions at hand, we offer a simple proof that multialgebras with the universal mapping property for the class of all multialgebras do not exist and that U does not have a left adjoint.

Is it tautological to call an action "wrongful discrimination?" Some philosophers and political theorists answer this question in the affirmative and claim that the term "discrimination" is intrinsically evaluative. Others agree that "discrimination" usually conveys the action’s moral wrongness but claim that the term can be used in a purely descriptive way. In this paper, we present two corpus studies and two experiments designed to test whether the folk concept of discrimination is evaluative. We demonstrate that the term has undergone (...) a historical development and is nowadays no longer used purely descriptively. Further, we show that this evaluation cannot be cancelled without yielding a contradiction. We conclude that the descriptive use of "discriminatory" is a thing of the past. (shrink)

Traduçáo do texto: Colóquio com o Senhor de Saci Sobre Epicteto e Montaigne, de Blaise Pascal, por Traduçáo: Jaimir Conte.

Ageing brings together biological, personal, and social horizons. Attempts to reduce it or to privilege one of these dimensions over the others fail to fully capture the phenomenon. The temporality of ageing presents an irreducible complexity. It is the inextricable intertwinement of three temporalities, three rhythms on different scales: biological time, personal-narrative time, and historical time. In all these dimensions something is of crucial concern: time and temporality. Yet, many philosophers who have thought about time (even those who take seriously (...) the lived experience of temporality) have paid little attention to ageing. Drawing from Heidegger, Scheler, and Schutz, this paper argues that ageing is an irreducible complex of different temporalities where one encounters the historicity of the world through a process of losing touch with it.

[Note: articles 1-5 are in English; Intro, Discussion, and Conclusion are in Portuguese.] Responsibility practices that are part of our daily lives involve, among other things, standards about how one should praise, blame, or punish people for their actions, as well as particular acts that follow those standards to a greater or lesser extent. A classical question in philosophy asks whether human beings can actually be morally responsible for what they do. This dissertation argues that addressing this classical question is (...) insufficient if one wants the investigation of moral responsibility to serve the goal of improving ordinary responsibility practices. As an alternative, I offer directions for an interdisciplinary investigation that I take to be in a better position to promote that goal. My argument is developed in five articles and a discussion section. The first four articles describe limitations of skeptical views, which deny the existence of moral responsibility. The first article assesses a skeptical argument based on results from neuroscience that intends to show that there is no free will. I argue that a premise in the argument—which says that choices are determined by events in the brain—is not supported by the available results. The second article argues that, despite the fact that existent results do not show that choices are determined by brain events, further studies in neuroscience could in principle do that. The third article begins the discussion of limitations that concern the implementability of some of the changes in responsibility practices recommended in skeptical approaches. Specifically, I describe challenges that attempts to reduce the severity of legal punishment are likely to face due to psychological facts about belief in free will and desire to punish. The forth article presents results from an original experiment that sought to test a hypothesis about the workings of belief in free will and the desire to punish, namely the hypothesis that the desire to punish causally affects beliefs about free will. Results failed to support the hypothesis. Finally, the fifth article presents what I call the enhancement model, i.e., a proposal about how to structure an interdisciplinary investigation that can promote the enhancement of ordinary responsibility practices. The final discussion section shows how the enhancement model overcomes some of the limitations of recent discussions about the existence of moral responsibility, which includes not just the skeptical views considered in earlier articles, but also views that affirm the existence of moral responsibility and free will. The central claim of this dissertation, therefore, is that the investigation of moral responsibility can be rearranged so as to further the goal of improving ordinary responsibility practices.

This paper focuses on Aristotle’s discussion of PNC in Metaphysics Gamma and argues that the argument operates at three different levels: ontological, doxastic, and semantic through the invocation of three philosophical personae: the first one can only state what is otherwise unprovable, the second one can only confirm that we should trust PNC, the third one denies PNC and must be silenced. Aristotle cannot prove what is beyond proof. This situation results in a fundamental ambiguity in the figure of the (...) philosopher. The Metaphysics is written from the standpoint of an investigative thinker who admits her puzzlement before a question that will forever remain open and imagines another philosopher who has achieved a god-like insight into the first principles of all things. The path from the first figure to the second one, however, remains an enigmatic leap. (shrink)

Résumé – Nous nous intéressons à l’enseignement et l’apprentissage de l’infini en classe de mathématiques en considérant les différences et les relations entre infini potentiel et infini actuel. Nous présentons les principaux éléments de notre étude philosophique, épistémologique et didactique, ainsi que trois situations visant à conduire un travail explicite avec les élèves sur ces questions en début de lycée. ---------------------------------------------------------------------------------------------------- --------------------------------- Abstract – We are interested in the teaching and learning of infinite in mathematics class, taking into account the relations (...) between potential infinite and actual infinite. We report the main elements of our current philosophical, epistemological and didactical study; we also present three mathematical situations that we consider relevant for this purpose and to be explored with 10 and 11 grade students.

The current literature on environmental sustainability acknowledges that habits are often shaped in private life and that experiences with environmental activities in a non-work setting positively influence environmental behaviors in the work domain. However, the conditions that lead individuals to behave responsibly at work based on their environmental commitment outside the workplace remain poorly understood. We address this issue by pursuing two objectives. First, we outline archetypes of environmental behavior on and off the job and classify individuals into four profiles: (...) Apathetic, Conformist, Citizen and Enthusiast. Second, we examine a set of organizational and psychological variables that explain the likelihood of behaving in accordance with the principles of an archetype in terms of pro-environmental behavior at work. Our findings show that supervisory support, job self-efficacy and affective commitment increase the likelihood of being green at work but that environmental management practices do not. The results differ according to the profiles identified, allowing a better understanding of employees’ commitment to environmental sustainability. We conclude the paper by discussing the theoretical and managerial implications of our findings. (shrink)

Diante dos embates e dilemas que vive o Brasil após o ano de 2016, fundamentalmente no que diz respeito a educação pública brasileira, o presente trabalho procurou se debruçar, refletir e verificar a posição e situação do educando brasileiro no cenário social nacional, e sobretudo escolar. Levamos em conta como base de configuração do indivíduo-sujeito e estudante sua identidade enquanto ser biopsicossocial, isso na perspectiva Aristotélica e Marxista de homem, tanto como ser dotado de razão, emoção, vontade, social, político, teleológico (...) (Aristóteles) e essencialmente ser de trabalho e histórico (Marx). (shrink)

Given the inevitability of our social dependencies, some social epistemologists have defended that dogmatism, rather than open-mindedness, is the more appropriate cognitive habit for laypeople to acquire good beliefs in specialized like the sciences. They claim that dogmatically relying on experts’ deliverances, rather than exercising one’s own intellectual virtues, like open-mindedness, is the best epistemic strategy for maximizing the acquisition of true beliefs and avoiding false ones. In this paper, I challenge this view by arguing that open-mindedness is a valuable (...) epistemic trait for laypeople who seek an appropriate pattern of epistemic dependence concerning scientific theories. While laypeople are generally incapable of fully understanding and evaluating scientific theories – an effort that only properly trained experts can undertake – they can still achieve some level of understanding of these theories. Such understanding is impeded by habits like dogmatism. Conversely, open-mindedness proves beneficial in these contexts as it disposes individuals to engage with and incorporate cognitively challenging ideas, such as many scientific theories. (shrink)

One of the most expected properties of a logical system is that it can be algebraizable, in the sense that an algebraic counterpart of the deductive machinery could be found. Since the inception of da Costa's paraconsistent calculi, an algebraic equivalent for such systems have been searched. It is known that these systems are non self-extensional (i.e., they do not satisfy the replacement property). More than this, they are not algebraizable in the sense of Blok-Pigozzi. The same negative results hold (...) for several systems of the hierarchy of paraconsistent logics known as Logics of Formal Inconsistency (LFIs). Because of this, these logics are uniquely characterized by semantics of non-deterministic kind. This paper offers a solution for two open problems in the domain of paraconsistency, in particular connected to algebraization of LFIs, by obtaining several LFIs weaker than C1, each of one is algebraizable in the standard Lindenbaum-Tarski's sense by a suitable variety of Boolean algebras extended with operators. This means that such LFIs satisfy the replacement property. The weakest LFI satisfying replacement presented here is called RmbC, which is obtained from the basic LFI called mbC. Some axiomatic extensions of RmbC are also studied, and in addition a neighborhood semantics is defined for such systems. It is shown that RmbC can be defined within the minimal bimodal non-normal logic E+E defined by the fusion of the non-normal modal logic E with itself. Finally, the framework is extended to first-order languages. RQmbC, the quantified extension of RmbC, is shown to be sound and complete w.r.t. BALFI semantics. (shrink)
