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)

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)

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)

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.

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.

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)

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)

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.

Tradução de correspondências trocadas entre Descartes e Elisabeth no ano de 1643, nas quais discutem a tese cartesiana da alma como imaterial e inextensa.

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)

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.

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)

[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.

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)

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.

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.

Gene clustering is a useful exploratory technique to group together genes with similar expression levels under distinct cell cycle phases or distinct conditions. It helps the biologist to identify potentially meaningful relationships between genes. In this study, we propose a clustering method based on multivariate normal mixture models, where the number of clusters is predicted via sequential hypothesis tests: at each step, the method considers a mixture model of m components (m = 2 in the first step) and tests if (...) in fact it should be m - 1. If the hypothesis is rejected, m is increased and a new test is carried out. The method continues (increasing m) until the hypothesis is accepted. The theoretical core of the method is the full Bayesian significance test, an intuitive Bayesian approach, which needs no model complexity penalization nor positive probabilities for sharp hypotheses. Numerical experiments were based on a cDNA microarray dataset consisting of expression levels of 205 genes belonging to four functional categories, for 10 distinct strains of Saccharomyces cerevisiae. To analyze the method’s sensitivity to data dimension, we performed principal components analysis on the original dataset and predicted the number of classes using 2 to 10 principal components. Compared to Mclust (model-based clustering), our method shows more consistent results. (shrink)

Diana Pérez criticizes Davidson’s argument for the thesis that there is no thought without language, and offers an alternative defense of that thesis on the basis of empirical studies on developmental psychology.

At the end, I offer a sketch of how a weaker (...) and more tenable version of the argument could be articulated. (shrink)

‘Justice’ is spoken of in two ways: the lawful and the fair. The law is a human construct that is devoted to the advantage of all, or to the advantage of the best, or to the advantage of those in power or to the advantage of those representing it – let it be the politician, the media, the TV presenter, the filmmaker. Thus, the law serves the production or the preservation of happiness within politics and business. The law commands us (...) to act according to the mean. A well-written law follows the mean well and a poorly written law does not. On the other hand, fairness is a principle sometimes materialised through the law and the given justice system. Fairness is the ultimate value pursued by both the common law and civil law traditions. However, its distribution through the law and the representation of this delivery varies. Does this mean that a different kind of justice is distributed? Through the teachings of Aristotle, this essay aims to deconstruct the notion of justice, by breaking down its two ingredients, the lawful and the fair, and by analysing the effect of their representation in modern European society. The relativity attached to the notion of justice is not a modern phenomenon, but a philosophical matter that can be analysed and indeed explained through the teachings of Aristotle and its contemporary students. The analysis will be developed in the context of convergent Europe, focusing on the role of the media and courts especially in relation to criminal justice. (shrink)

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. Em uma série de contribuições que tiveram um impacto significativo na respectiva literatura, Gomes elaborou uma concepção sobre o livre-arbítrio e argumentou que sua existência é consistente com descobertas científicas recentes, especialmente na neurociência. 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.].

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 2016, Béziau introduces a restricted notion of paraconsistency, the so-called genuine paraconsistency. A logic is genuine paraconsistent if it rejects the laws $\varphi,\neg \varphi \vdash \psi$ and $\vdash \neg (\varphi \wedge \neg \varphi)$. In that paper, the author analyzes, among the three-valued logics, which of them satisfy this property. If we consider multiple-conclusion consequence relations, the dual properties of those above-mentioned are $\vdash \varphi, \neg \varphi$ and $\neg (\varphi \vee \neg \varphi) \vdash$. We call genuine paracomplete logics those rejecting (...) the mentioned properties. We present here an analysis of the three-valued genuine paracomplete logics. A very natural twist structures semantics for these logics is also found in a systematic way. This semantics produces automatically a simple and elegant Hilbert-style characterization for all these logics. Finally, we introduce the logic LGP which is genuine paracomplete is not genuine paraconsistent, not even paraconsistent and cannot be characterized by a single finite logical matrix. (shrink)

In this paper two systems of AGM-like Paraconsistent Belief Revision are overviewed, both defined over Logics of Formal Inconsistency (LFIs) due to the possibility of defining a formal consistency operator within these logics. The AGM° system is strongly based on this operator and internalize the notion of formal consistency in the explicit constructions and postulates. Alternatively, the AGMp system uses the AGM-compliance of LFIs and thus assumes a wider notion of paraconsistency - not necessarily related to the notion of formal (...) consistency. (shrink)

Two systems of belief change based on paraconsistent logics are introduced in this article by means of AGM-like postulates. The first one, AGMp, is defined over any paraconsistent logic which extends classical logic such that the law of excluded middle holds w.r.t. the paraconsistent negation. The second one, AGMo , is specifically designed for paraconsistent logics known as Logics of Formal Inconsistency (LFIs), which have a formal consistency operator that allows to recover all the classical inferences. Besides the three usual (...) operations over belief sets, namely expansion, contraction and revision (which is obtained from contraction by the Levi identity), the underlying paraconsistent logic allows us to define additional operations involving (non-explosive) contradictions. Thus, it is defined external revision (which is obtained from contraction by the reverse Levi identity), consolidation and semi-revision, all of them over belief sets. It is worth noting that the latter operations, introduced by S. Hansson, involve the temporary acceptance of contradictory beliefs, and so they were originally defined only for belief bases. Unlike to previous proposals in the literature, only defined for specific paraconsistent logics, the present approach can be applied to a general class of paraconsistent logics which are supraclassical, thus preserving the spirit of AGM. Moreover, representation theorems w.r.t. constructions based on selection functions are obtained for all the operations. (shrink)

By using multilevel mediation involving 322,589 posts made by 384 musicians over 104 weeks, we simultaneously analyze the short-term and long-term effects of charity-related signaling on sales, with social media engagement as the mediator. Specifically, we compare the effects of charity-related signals with those of two other types of signals: mission-related (i.e., promoting music and commercial products) and non-mission-related (i.e., other posts that do not relate to the other two categories). In the short term, the indirect effect of using charity (...) signaling on sales (through engagement) is positive, though smaller than the effects of mission-related and non-mission related signals. However, in the long term, the indirect effect of regularly using charity-related signaling on sales (through long-term engagement) is greater than for the effects involving the other types of signals. We derive from these findings three main implications for the business ethics literature. First, in the long term, the mutual economic benefits of charity signaling should encourage both entities (i.e., musicians and charities) to go beyond short-term, transactional philanthropy. Second, because it is profitable for musicians to partner with charities in the long-term, our research argues that charities have extensive bargaining power in such co-branding decisions. Third, our research highlights the importance of studying the longitudinal aspects of co-branding decisions involving non-profit organizations; the financial outlook of such decisions could greatly vary depending on the timeframe (i.e., short vs. long).

This paper presents REAL, a Real-Valued Attribute Classification Tree Learning Algorithm. Several of the algorithm's unique features are explained by úe users' demands for a decision support tool to be used for evaluating financial operations strategies. Compared to competing algorithms, in our applications, REAL presents maj or advantages : (1) The REAL classification trees usually have smaller error rates. (2) A single conviction (or trust) measure at each leaf is more convenient than the traditional (probability, confidence-level) pair. (3) No need (...) for an external pruning criterion. (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)

We examine the most famous controversy between economists as a means of shedding fresh light on the current debate about economic methodology. By focusing on the controversy as the primary unit of analysis, we show how methodological considerations are but one of a whole set of stratagems strategically employed by each opponent. We argue that each opponent's preference for a particular kind of stratagems expresses his own specific scientific style (within the general scientific and cultural style of an age). We (...) also describe a dynamic dimension of the controversy, independent of the participants' intentions. Such a dimension is analysed in a "cycle" of the controversy, which begins with a well-defined issue and expands to additional topics, without reaching a "solution" to the initial issue. The definition and re-definition of the issue(s) at stake and of the difference between both participants is an essential and recurrent feature of such cycles; the conclusion of a cycle does not imply a real "closure" of the controversy, but only that each opponent has reached a satisfying degree of self-clarification. The controversy, thus, does not yield persuasion -- its ostensible aim. Rather, its "benefit" seems to lie in an unintended result -- clarification and deepening of contrasting approaches to the discipline -- due to its peculiar dynamics. In so far as the history of a discipline requires a reconstruction of such contrasts, it is indispensable for it to take into account the controversies where they emerge, and to view both the positive doctrines and the methodological posture of the contenders as parts of a wider framework, that is a scientific style.

Há diferenças entre o EU desse SER nos dois momentos, vivencias, experiencias e movimentos distintos? No útero materno e ou após o nascimento? E o que dizer sobre a questão da consciência e inconsciência desse SER e EU simultaneamente? Há consciência e inconsciência? Apenas uma delas?! Nenhuma!? E se houver uma apenas ou as duas, elas estão ativas? São iguais no útero e após o nascimento? Podem mudar ou se modificarem? Poderíamos dizer sobre um EU, consciência e inconsciente antes de nascer e depois de nascer? Só existe um EU depois de sair do útero materno?

Desse modo, realizaremos um trabalho de busca e resgate histórico do Eu, do Consciente e Inconsciente da espécie humana, no qual produções como as de Freud serão nossa base inicial e de discussões críticas quanto ao que vem sendo confeccionado sobre a história e atuação dessas esferas psíquicas da humanidade.

Are there differences between the I of this BEING in the two distinct moments, experiences, and movements? In the womb or after birth? And what about the question of consciousness and unconsciousness of this BEING and I simultaneously? Is there consciousness and unconsciousness? Only one of them? None? And if there is only one or both, are they active? Are they the same in the womb and after birth? Can they change or modify each other? Could we say about an I, consciousness and unconscious before birth and after birth? Is there only an I after leaving the mother's womb? Is there only consciousness and unconsciousness after the BEING and I are born? These are the questions that we will try to work on in this essay and its current problems. It is important to inform that the notion and conception of conscious and unconscious discussed here will not be restricted to moral, juridical, religious, formal, cultural and social aspects, they will be in the dimension and agenda of the neuroscience, biophysiological, biopsychic and philosophical areas. In this way, we will carry out a historical search and rescue work of the "I", the Conscious and the Unconscious of the human species, in which productions such as those of Freud initial base and of critical discussions about what has been done about the history and performance of these psychic spheres of humanity. Thus, we will carry out a historiographical movement of these components of the psyches, situating them in historical, geographic, cultural, biological, body and mental time and space.------|||||-----RESUMEN: ¿Cuándo surge el YO del SER, en el feto o en el recién nacido? ¿Existen diferencias entre el YO de este SER en los dos momentos, diferentes vivencias, vivencias y movimientos? ¿En el útero de la madre y/o después del nacimiento? ¿Y qué podemos decir del tema de la consciencia e inconsciencia de este SER y YO simultáneamente? ¿Existe conciencia e inconsciencia? ¡¿Solo uno de ellos?! ¿¡Ninguno!?
