Com a evolução da tecnologia, é cada vez mais comum encontrar robôs de conversação com maior capacidade de argumentar em um diálogo. Embora estejam muito longe de se igualarem a seres humanos nesse quesito, há vários desses robôs com performances significativas ao realizar essa tarefa. Nesse sentido, este estudo tem por objetivo discutir basicamente o conceito de ethos em máquinas que simulam personalidades humanas pré-determinadas. O estudo baseia-se em consulta bibliográfica interdisciplinar voltada às áreas de Linguística, Discurso, Retórica, Processamento de (...) Linguagem Natural, Inteligência Artificial e Processamento de Dados. A observação dos exemplos utilizados para comparação sugere que mais pesquisas na mesma direção devem ser realizadas, tendo em vista que a evolução dessas máquinas é exponencial e constante.

We investigate certain Brouwer-Zadeh lattices that serve as abstract counterparts of lattices of effects in Hilbert spaces under the spectral ordering. These algebras, called PBZ*-lattices, can also be seen as generalisations of orthomodular lattices and are remarkable for the collapse of three notions of “sharpness” that are distinct in general Brouwer-Zadeh lattices. We investigate the structure theory of PBZ*-lattices and their reducts; in particular, we prove some embedding results for PBZ*-lattices and provide an initial description of the lattice of PBZ*-varieties.

A brief introduction to the main philosophical problems and theories about the nature of holes and such-like nothingnesses.

After the collapse of the Soviet Union, the great fear that formerly attended the threat of nuclear warfare has been replaced by other more intangible and disturbing fears: first a fear of migrants, then a fear of Islamic terrorism, and finally a fear of a traditionally persecuted minority like the Roma people. The politics now marketed, the entirety of the slogans now adopted by the political parties, specifically emphasise such fears. In the first pace, the slogans of the Right feed (...) and spread these fears precisely in order to enhance their own legitimacy. Along with such slogans, and sometimes in the closest connection with them, there operates a potent mechanism of fear: the totality of the press and the television media, and all the ways by means of which this diffuse social imaginary is produced. If the world of politics were a market – and it looks as if that is what it has now become – one could say that the principal commodity on offer is exactly fear. As in the economic market, the “political agents” sell themselves, in this case by disseminating throughout the social body a fear which claims that it alone is conducive to real security. And this means that the process of political competition transpires almost entirely within a “persecutory” perspective in accordance with victimising model of the scapegoat. Thus civil rights are the first things that come under threat: in the short term the civil rights of the victims, and in the long term those of the “citizens” as well. (shrink)

In the recent literature across philosophy, medicine and public health policy, many influential arguments have been put forward to support the use of randomization procedures to allocate scarce life-saving resources. In this paper, I provide a systematic categorization and a critical evaluation of these arguments. I shall argue that those arguments justify using RAND to allocate SLSR in fewer cases than their proponents maintain and that the relevant decision-makers should typically allocate SLSR directly to the individuals with the strongest claims (...) to these resources rather than use RAND to allocate such resources.

Introduction -- Inquiry as the logic of practical reasoning -- From reasoning to judgment -- Expressive inquiry -- The public sphere -- Pragmatism, pluralism, and the fact of relativism -- A pragmatic theory of objectivity -- Why justification matters? -- Pragmatism as an epistemology of practice.

The question of rationality and of its role in human agency has been at the core of pragmatist concerns since the beginning of this movement. While Peirce framed the horizon of a new understanding of human reason through the idea of inquiry as aiming at belief-fixation and James stressed the individualistic drives that move individuals to action, it is in Dewey’s writing that we find the deepest understanding of the naturalistic and normative traits of rationality considered as the qualifying attribute (...) of human agency. Recent developments in moral and political philosophy as well as in general pragmatist scholarship have shown a renewal of interest in the role of human reason in agency, both with respect to control of conduct (decisions about how to act) and with respect to normative attitudes (considerations of what is good and right). In this article I will examine some features of Dewey’s epistemology which are particularly promising for the elaboration of a theory of practical rationality based on pragmatist sources. In particular, I will focus on Dewey’s notion of “judgment of practice” in order to frame a distinctively Deweyan approach to practical rationality. In order to point out the specificity of Dewey’s epistemological framework, I will refer to it as an “epistemology of practice”i. The aim of this article is to clarify the epistemological meaning of the concepts of articulation and transformation, that Dewey places at the heart of his theory of inquiry. Part of my argument consists in showing that through these notions Dewey aimed at broadening the conception of rationality, bringing it beyond the reach of the standard notions of analysis and synthesis and of induction, deduction, and abduction. Once the specificity of Dewey’s conception of rationality will have been demonstrated, I will proceed to show some of its implications in the explanation of the rationality of human agency with reference to practical reasoning and value assessment. I will then conclude the article by drawing some implications of Dewey’s theory of judgment for a broader epistemology based upon the acknowledgment of the primacy of practice. (shrink)

The aim of this paper is to give a description of the free algebras in some varieties of Glivenko MTL-algebras having the Boolean retraction property. This description is given (generalizing the results of [9]) in terms of weak Boolean products over Cantor spaces. We prove that in some cases the stalks can be obtained in a constructive way from free kernel DL-algebras, which are the maximal radical of directly indecomposable Glivenko MTL-algebras satisfying the equation in the title. We include examples (...) to show how we can apply the results to describe free algebras in some well known varieties of involutive MTL-algebras and of pseudocomplemented MTL-algebras. (shrink)

The theory of the firm initially developed by Ronald Coase has made explicit the political nature of firms by putting hierarchy at the heart of the economic process. Theories of workplace democracy articulate this intuition in the normative terms of the conditions under which this political power can be legitimate. This paper presents an organizational theory of workplace democracy, and contends that the democratization of firms requires that we take their organizational dimension explicitly into account. It thus construes democracy as (...) an organizational principle and juxtaposes it to market, hierarchy, and norm-compliance as rival principles for the organization of economic activities. Attempts to construe democracy as an organizational principle with unique features in the tradition of transaction-cost economics are discussed before proposing an innovative solution based on an updated version of grid/group cultural theory of politics, adjusted to accommodate the basic requirements of democratic theory.

This article develops the hypothesis that the intensified self-portraying and self-exhibition so characteristic of many of today’s social-media practices do not correlate with intensified self-reflection but, on the contrary, indicate a tendency towards self-loss. However, it would be wrong-headed to blame the social networks for distracting from real life. Rather, it is the loss of reality in the real life of contemporary life-worlds that renders social networks an enticing narcissistic way out of an existential horror vacui manifesting itself in new (...) ways within digital culture. In diagnostic terms we can speak of a cultural change towards a posthuman narration of the self. Three vectors of this posthuman narration of the self are distinguished: From word to number, from mechanism to automatism, and from option to obligation. (shrink)

Mathematical game theory – developed starting from the publication of The Theory of Games and Economic Behavior , by John von Neumann and Oskar Morgenstern – aims to outline an ideal model of behaviour of rational agents involved in some interaction with other rational agents. For this reason, game theory has immediately attracted the attention of philosophers dealing with practical rationality and, since the fifties, has been applied to the analysis of several issues concerning ethics and philosophy of politics. Here (...) we will focus on one of the most interesting applications of game theory to ethical-political inquiry, i.e., with the game theoretic analysis of some problems related to the evolution of moral norms. Firstly, we will provide a short outline of the development of game theory, which has lead to the formulation of a plurality of different game theories. It will be shown that such theories can be classified in two main groups: rationalistic game theories –in two different versions: classical and epistemic – and evolutionary game theories. Moreover, some basic elements of classical game theory will be introduced and the key ideas of epistemic and evolutionary game theories will be illustrated. Afterwards, the main approaches developed within the ethical-political applications of game theory will be shortly described. Finally, some results obtained in the last twenty years by the researchers who have analysed the evolution of moral norms by the conceptual tools of evolutionary and epistemic game theories, will be examined.

Nonhuman animals are the most prominent alterity with which humans have engaged in interaction and in comparative self-definition. The reference point of nonhuman alterity is central both to the development of humanism and of posthumanism. In the complex and nonlinear interfaces with nonhumans, humans are extensively hybridized in a process that defines their very humanity. Understanding humans as open and interactive animals rather than as closed and autarchic entities is indispensable to the dismantling of humanism and the development of posthuman (...) thought. Nonhuman and human animals host and are hosted by one another in dynamic and emergent relations. (shrink)

In this paper I offer a first account of a practice-based conception of normativity for the political domain. This standpoint is used to relocate the most sophisticated normative practices of justification and critique within an experience-based framework, that of the human being as a “normative creature.” I begin by discussing the two major paradigms in political theory, showing that their neglect of this broad framework of normativity is a serious drawback. I then proceed to articulate the central elements of a (...) practicebased account of normativity: the notions of normative practices and normative orders, and an account of the rationality potential of normativity as practice.

This article contains a case study of some innovative early fourteenth-century conceptions of the temporal structure of substantial change. An important tenet of thirteenth-century scholastic hylomorphism is that substantial change is an instantaneous process. In contrast, three early fourteenth-century Aristotelian commentators, first Walter Burley and then John Buridan and Albert of Saxony, progressively develop a view on which substantial change is linked to temporal duration. This process culminated, in Buridan and Albert of Saxony, with the explicit recognition of the temporally (...) extended nature of some (if not most) instances of substantial change. This article sheds light on this neglected episode in the history of late medieval hylomorphism taking as its point of departure these commentators’ discussions of the issue of minima naturalia, i.e., the issue of the lowest possible limit of any division of substantial forms coming about through the potentially infinite division of the matter they inform. In short: is there a piece of matter so small that no substantial form can possibly inhere in it? (shrink)

This article addresses the theoretical difficulty of justifying the use of penal coercion in circumstances of marked, unjustified social inequality. The intuitive belief behind the text is that in such a context—that of an indecent State—justifying penal coercion becomes very problematic, particularly when directed against the most disfavored members of society.

I defend a cognitive theory of pictures, according to which the central paradigm of our concept of a picture is the representational picture, i.e., the one which induces recognitional abilities in the perceiver. I show how to classify different pictorial styles in terms of their distance from the paradigm, and I criticize alternative accounts.

The present contribution aims at defining the relation between cybernetics and social theory from the perspective of society as order. After an historical framework of the cybernetic movement, a careful reading of the works of Norbert Wiener, in which he introduced the concept of feed-back and the idea of information society, has revealed a keen awareness about the social effects of technological innovation. Among the social scientists who had made use of cybernetic concepts, it has been considered the work of (...) Karl Deutsch, which was one of the first completely cybernetic perspective for the study of political and social phenomena. The main conclusion is that cybernetics, as a meeting point between different disciplines, has produced an image of self-regulated society in line with the image of society as order. (shrink)
