This study analyses the attitudes of university students towards unethical behaviour in the individual and organisational environments, and relates these attitudes to tolerance of corruption in their future professional lives. The results show a positive relationship between attitudes towards unethical behaviour in both environments, as well as tolerance towards acts of corruption, based on a virtual perception survey. Despite the general rejection attitude by students of such behaviour and acts, the rejection diminishes as their degree programme progresses. This study contributes (...) to our understanding of the tolerance of university students towards corruption, and to revealing how this attitude could explain tolerance towards this phenomenon in their future professional lives.

The concept of measuring inconsistency in information was developed by John Grant in a 1978 paper in the context of first-order logic. For more than 20 years very little was done in this area until in the early 2000s a number of AI researchers started to formulate new inconsistency measures primarily in the context of propositional logic knowledge bases. The aim of this volume is to survey what has been done so far, to expand inconsistency measurement to other formalisms, to (...) connect it with related topics, and to provide ideas for further research in a topic that is particularly relevant now in view of the many inconsistencies in the massive amount of information available. The book contains 11 chapters. The first chapter, by John Grant, gives his original motivation for starting this field, explains why it was formulated in a highly mathematical manner, presents important material that was omitted from the original paper, and provides ideas about the use of dimensions in measuring inconsistency. The second chapter, by Matthias Thimm, is a survey that covers most of the research on inconsistency measures up to 2017. The other 9 chapters, all by experts either in inconsistency measures, or in the topic under consideration, or both, connect inconsistency measures with argumentation, disjunctive logic programming, fuzzy logic systems, modal logics, multiset representation, paraconsistent consequence, probabilistic logic, relational databases, and spatio-temporal databases."-- back cover.

Abstract. The notion of similarity has been studied in many areas of Computer Science; in a general sense, this concept is defined to provide a measure of the semantic equivalence between two pieces of knowledge, expressing how “close” their meaning can be regarded. In this work, we study similarity as a tool useful to improve the representation of arguments, the interpretation of the relations between arguments, and the semantic evaluation associated with the arguments in the argumentative process. In this direction, (...) we present a novel mechanism to determine the similarity between two arguments based on descriptors representing particular aspects associated with these arguments. This mechanism involves a comparison process influenced by the context in which the process develops, where this context provides the relevant aspects that need to be analyzed in the application domain. Then, we use this similarity measure as a quantity to compute the result of attacks and supports in the argumentation process. These valuations, applied to a Bipolar Argumentation Frameworks, allowed us to refine the argument relations, providing the tools to establish a family of new argumentation semantics that considers the similarity between arguments as a crucial part for the argumentation process.

We present a novel argumentation-based method for finding and analyzing communities in social media on the Web, where a community is regarded as a set of supported opinions that might be in conflict. Based on their stance, we identify argumentative coalitions to define them; then, we apply a similarity-based evaluation method over the set of arguments in the coalition to determine the level of cohesion inherent to each community, classifying them appropriately. Introducing conflict points and attacks between coalitions based on (...) argumentative (dis)similarities to model the interaction between communities leads to considering a meta-argumentation framework where the set of coalitions plays the role of the set of arguments and where the attack relation between the coalitions is assigned a particular strength which is inherited from the arguments belonging to the coalition. Various semantics are introduced to consider attacks’ strength to particularize the effect of the new perspective. Finally, we analyze a case study where all the elements of the formal construction of the formalism are exercised. (shrink)

En las últimas décadas la apropiación y construcción de archivos ha ido ganando terreno dentro de las prácticas artísticas, permitiendo visibilizar las políticas de archivo y los órdenes sociales a los que responden. Al mismo tiempo, han propuesto modos divergentes de activación de la memoria, problematizando creativamente las jerarquías y protocolos tradicionales, constituyéndose, así, en lo que podemos llamar estrategias anarchivísticas. Considerando que, en el seno de la cultura digital, la IA (Inteligencia Artificial) se ha vuelto clave en la gestión (...) de la información, el presente artículo se pregunta de qué manera la utilización artística de esta tecnología contribuye a ofrecer nuevos enfoques para pensar el archivo, el patrimonio y la memoria. Dentro de la madeja de prácticas existentes, jalaremos de dos hilos: 1) por un lado, las tácticas apropiacionistas que operan activando nuevas lecturas sobre archivos ya constituidos; 2) por otro, aquellas que proponen la construcción de archivos nuevos, generalmente abarcando elementos dispersos u otrora ignorados. Ahondaremos en estas tendencias centrándonos en dos casos que abordan específicamente el patrimonio fílmico –Jan Bot y Oráculo de Capturas de Pantalla– identificando sus estrategias y características.

Providing a novel multi-disciplinary theorization of memory politics, this insightful Handbook brings varied literatures into a focused dialogue on the ways in which the past is remembered and how these influence transnational, interstate, and global politics in the present. With case studies from Africa, East and Southeast Asia, Europe, South America, and the United States, the Handbook focuses on the political features of historical memory in international relations. Chapters examine key concepts of memory politics, including accountability, commemoration and memorialization, the (...) Europeanization of memory, and the politics of trauma and victimhood, as well as analyzing different sites of memory, from the human body and memorial sites to media, film, and television. It also answers essential questions such as who and what determines the relevance of the past in the present; how does memory become a political question; and what are the political effects and ethical implications of its mobilization? Exploring the links between the politics of memory, international ethics, law, and diplomacy, this stimulating Handbook will be essential reading for students and scholars of politics and international relations, cultural studies, history, and transitional justice. Its discussion of notable agents and practices of memory politics will also be beneficial for practitioners working in human rights, politics, and public policy. (shrink)

In this Chapter, Maria Kronfeldner discusses whether psychological essentialism is a necessary part of dehumanization. This involves different elements of essentialism, and a narrow and a broad way of conceptualizing psychological essentialism, the first akin to natural kind thinking, the second based on entitativity. She first presents authors that have connected essentialism with dehumanization. She then introduces the error theory of psychological essentialism regarding the category of the human, and distinguishes different elements of psychological essentialism. On that basis, Kronfeldner connects (...) historical, socio-psychological, and philosophical insights in order to show that although essentialism can act as a catalyst for dehumanization, it is not necessary for it. Examples relate to dehumanization in the context of colonialism and evolutionary thinking, to the history of dehumanizing women from Aristotle to 19th-century craniology, and to contemporary self-dehumanization and ‘lesser mind’ attribution.

Este artículo consiste de una referencia razonada a un conjunto definido de conceptos desarrollados en el seno de lo que ha llegado a conocerse como estudios de la gubernamentalidad. Comienza narrando sucintamente las vicisitudes conceptuales de un grupo de estudiosos anglosajones cuya apuesta intelectual, inspirada en gran medida por la analítica foucaultiana del poder, fue pensar la política sin reducirse—ni privilegiar—al Estado en tanto principio explicativo. A continuación, tras poner el foco sobre la noción de “procesos de subjetificación”, demuestra en (...) qué sentido la conformación de subjetividades adquiere un lugar central en el marco del análisis del poder político moderno. La relevancia complementaria que para dicho enfoque presentan las “racionalidades” y las “tecnologías”, el pensamiento y las prácticas, es ilustrada a partir de la consideración del papel desempeñado por las disciplinas “psi” en la constitución de sujetos gobernables en el contexto de las democracias liberales. Finalmente, el artículo concluye aludiendo al interés creciente del que son objeto las biotecnologías en los últimos estudios de N. Rose. (shrink)

La cuestión de la subjetividad en el campo de la comunicación. Una reflexión epistemológica.

Maria Kronfeldner’s Preface and Introduction to the Routledge Handbook of Dehumanization maps the landscape of dehumanization studies. She starts with a brief portrayal of the history of the field. The systematically minded sections that follow guide the reader through the resulting rugged landscape represented in the Handbook’s contributions. Different realizations, levels, forms, and ontological contrasts of dehumanization are distinguished, followed by remarks on the variety of targets of dehumanization. A discussion on valence and emotional aspects is added. Causes, functions, and (...) consequences of dehumanization, and the prospects for reducing or undoing it, are introduced. The systematic overview closes with a discussion of some important theoretical complexities that arise in studying dehumanization. After these systematic sections, the scholarly work on dehumanization gets situated in the broader intellectual landscape of debates about the ‘human’ in the humanities and social sciences. The Introduction ends with some notes on scope, limitations, and intended readership of the Handbook. (shrink)

El propósito de este artículo es el de investigar algunos conceptos de la Filosofía del límite de Eugenio Trías y de la noción de “genealogía” propuesta por Michel Foucault.Expuestos a partir de tres trilogías de imágenes, se desprenden diálogos que ayudan a pensar cómo se develan esas sombras de la existencia que se esconden en los pliegues de lo racional. La gran pregunta tiene que ver con el “entorno matricial” y con el movimiento de “exilio y éxodo” del ser. Las (...) imágenes elegidas funcionan como “hitos genealógicos” foucoultianos: esas “verdades sin apariencia” y “sin historia” que emergen presentando vinculaciones que inducen a otras lecturas hermenéuticas.El artículo vuelve siempre otra vez -a partir de algunas de las imágenes elegidas- a pensarse desde San Juan / Argentina, sitio que tensiona e implica, en este caso, la existencia de todas estas reflexiones y su conexión visual.

Food systems transformations require coherent policies and improved understandings of the drivers and institutional dynamics that shape (un)sustainable food systems outcomes. In this paper, we introduce the Chilean National Organic Agriculture Law as a case of a policy process seeking to institutionalize a recognized pathway towards more sustainable food systems. Drawing from institutional theory we make visible multiple, and at times competing, logics (i.e., values, assumptions and practices) of different actors implicated in organic agriculture in Chile. More specifically, our findings (...) identify five main institutional transformative logics underpinning the interests and actions of organic actors. However, we find that the Law was not motivated by these logics and did not advance them. Rather, the Law was designed to support a market niche targeted to elite consumers and to reinforce agricultural exports. As a result, the Law constrains rather than enables the practice of organic agriculture and access to organic food by consumers, especially at the domestic level. We note that attention to institutional logics in the analysis of food systems, and specifically food system transformation, is relevant to more comprehensive assessments of the transformational potential of food systems policies. We conclude that there is a need to further consider and make visible the way in which different drivers (i.e., laws) are constituted through and by diverse, and often competing, institutional logics.

A striking feature of atrocities, as seen in genocides, civil wars or violence against certain racial and ethnic groups, is the attempt to dehumanize – to deny and strip human beings of their humanity. Yet the very nature of dehumanization remains relatively poorly understood. The Routledge Handbook of Dehumanization is the first comprehensive and multidisciplinary reference source on the subject and an outstanding survey of the key concepts, issues and debates within dehumanization studies. Organized into four parts, the Handbook covers (...) the following key topics: (I) The history of dehumanization from Greek Antiquity to the Twentieth century, contextualizing the oscillating boundaries, dimensions, and hierarchies of humanity in the history of the ‘West’. (II) How dehumanization is contemporarily studied with respect to special contexts: as part of social psychology, as part of legal studies or literary studies, and how it connects to the idea of human rights, disability and eugenics, the question of animals, and the issue of moral standing. (III) How to tackle its complex facets, with respect to the perpetrator’s and the target’s perspective, metadehumanization and selfdehumanization, rehumanization, social death, status and interdependence, as well as the fear we show towards robots that become too human for us. (IV) Conceptual and epistemological questions on how to distinguish different forms of dehumanization and neighboring phenomena, on why dehumanization appears so paradoxical, and on its connection to hatred, essentialism, and perception. -- Essential reading for students and researchers in philosophy, history, psychology, and anthropology this Handbook will also be of interest to those in related disciplines such as politics, international relations, criminology, legal studies, literary studies, gender studies, disability studies, or race and ethnic studies, as well as readers from social work, political activism, and public policy --- Table of Contents: Introduction. 1.

Silence is reserved for what cannot be verbally expressed. The well-known Wittgensteinian quote summarizes an established understanding of the relationship between language and silence: because language is not enough to account for reality and thinking, it must be transcended by other means of expression, like music or silence. But what if the opposite is the case and silence is not the extension but the precondition of language, the ultimate source of meaning? This paper explores how this is the phenomenological and (...) Derridean philosophical framework of Coetzee’s novels, a literary universe created from the will to signify and build singular meanings. (shrink)

Conceptions of evil have changed dramatically over time, and though humans continue to commit acts of cruelty against one another, today we possess a clearer, more moral way of analyzing them. In _Narrating Evil_, María Pía Lara explores what has changed in our understanding of evil, why the transformation matters, and how we can learn from this specific historical development. Drawing on Immanuel Kant's and Hannah Arendt's ideas about reflective judgment, Lara argues that narrative plays a key role in (...) helping societies acknowledge their pasts. Particular stories haunt our consciousness and lead to a kind of examination and dialogue that shape notions of morality. A powerful description of a crime can act as a filter, helping us to draw conclusions about what constitutes a moral wrong, and public debates over these narratives allow us to construct a more accurate picture of historical truth, leading to a better understanding of why such actions are possible. In building her argument, Lara considers Greek tragedies, Shakespeare's depictions of evil, Joseph Conrad's literary metaphors, and movies that portray human cruelty. Turning to such philosophers and writers as Jürgen Habermas, Walter Benjamin, Primo Levi, Giorgio Agamben, and Ariel Dorfman, Lara defines a reflexive relationship between an event, the narrative of the event, and the public reception of the narrative, and she proves that the stories of perpetrators and sufferers are always intertwined. The process of disclosure, debate, and the public fashioning of collective judgment are vital methods through which we make sense not only of new forms of cruelty but of past crimes as well. _Narrating Evil_ describes the steps of this process and why they are a crucial part of our attempt to build a different, more just world.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.1 (2003) 131-132 [Access article in PDF] Christia Mercer. Leibniz's Metaphysics: Its Origins and Development. New York: Cambridge University Press, 2001. Pp. xiii + 528. Cloth, $80.00. Christia Mercer's massive study is aimed at unearthing the hidden roots of Leibniz's metaphysics by placing the German philosopher back in the intellectual context within which his thought first took shape. In so doing she stresses (...) the fundamental importance of Leibniz's early years for the development of his philosophy. In particular she convincingly argues for the key role played by Leibniz's early exposure to the thought of eclectic thinkers (including his teachers) who were trying to build a new philosophical synthesis centered around the key tenets of Christian theology and combining elements of Aristotelianism, Platonism, and (in at least some cases) the new mechanical philosophy of nature.One of Mercer's central theses is that the methodological and metaphysical commitments that Leibniz developed during his youth formed the bedrock of his mature philosophy (23). More precisely, her bold claim is that Leibniz's core metaphysics (including the complete concept account of substance) was constructed in 1668-71, re-examined and slightly developed in 1672-79, and then used for the rest of his long philosophical career (18, 470). The key inspirational forces driving the development of Leibniz's philosophy, in her view, had even earlier origins. In the mid-1660s Leibniz did not yet have a fully formulated metaphysics; but he already possessed very definite philosophical objectives which were to guide the development of his metaphysics and form the unstated assumptions underlying his mature thought (40). Mercer identifies these unstated assumptions as a "Metaphysics of Method," a "Metaphysics of Substance," and a "Metaphysics of Divinity," all of which she finds fully developed in his early thought (468-9).According to Leibniz's "Metaphysics of Method" (examined in part I), there exists a truth beneath the prominent philosophical schools which can and ought to be discovered. This conciliatory methodology was Leibniz's answer to the political, religious, and philosophical chaos around him. He was deeply convinced that his brilliantly original eclectic metaphysics would provide the foundation of philosophical, theological, and even political peace. Leibniz's "Metaphysics of Substance," Mercer argues in part II, melded an Aristotelian approach to substance with a mechanical physics and originated at the very outset of his intellectual carrier in an attempt to solve specific theological problems (e.g., those of the incarnation and resurrection). Platonism in turn offered the material for Leibniz's "Metaphysics of Divinity" (explored in part III), that is, for his conception of the relationship between God and creatures. The fourth and final part of Mercer's book takes her analysis of Leibniz's writings up to 1679 and describes the laying of the foundations of his mature metaphysics. She concludes not only that Leibniz proposed the doctrine of pre-established harmony prior to his departure for Paris in March 1672, but also, more generally, that the other tenets of Leibniz's mature thought, including his theory of truth, grew naturally out of his early metaphysics (see, in particular, 2, 15-8, 47, 52, 169-70, 250-2, 300-1, 472).Throughout the book Mercer describes her interpretation as "startling," "unfamiliar," "dramatic," and "surprising," and fears that "readers may balk" at her conclusions since "so much of Leibniz's thought has escaped us for so long" (see, for instance, 1, 9, 471). Some readers may feel, on the contrary, that she has underestimated the extent to which several of her central theses—such as the importance of the earliest stages of Leibniz's philosophical development in general and of eclecticism, theological problems, and Platonism, as well as Aristotelianism within that development in particular—are already reflected in the [End Page 131] best recent traditions of international Leibniz scholarship. But her book undoubtedly breaks new ground and remains an important contribution to an exciting field which cannot and will not be ignored. While international Leibniz scholarship may not absorb some of this book's more... (shrink)

The purpose of this paper is twofold: first we outline a version of non-descriptivism, ‘minimal expressivism’, leaving aside certain long-standing problems associated with conventional expressivist views. Second, we examine the way in which familiar expressivist results can be accommodated within this framework, through a particular interpretation that the expressive realm lends to a theory of meaning. Expressivist theories of meaning address only a portion of the classical problems attributed to this position when they seek to explain why the expressions they (...) deal with have a given meaning. A position can nevertheless be termed ‘expressivist’ – in the minimal sense that we favor – based simply on the following key features of the meaning of these expressions: they can be used as functions of propositions, and they are not used to describe the way the world is.

Postmodern political critiques speak of the death of ideology, the end of history, and the postsecular return of religious attitudes, yet radical conservative theorists such as Mark Lilla argue religion and politics are inextricably intertwined. Returning much-needed uncertainty to debates over the political while revitalizing the very terms in which they are defined, María Pía Lara explores the ambiguity of secularization and the theoretical potential of a structural break between politics and religion. For Lara, secularization means three things: the (...) translation of religious semantics into politics; a transformation of religious notions into political ideas; and the reoccupation of a space left void by changing political actors that gives rise to new conceptions of political interaction. Conceptual innovation redefines politics as a horizontal relationship between governments and the governed and better enables societies (and individual political actors) to articulate meaning through action--that is, through the emergence of new concepts. These actions, Lara proves, radically transform our understanding of politics and the role of political agents and are further enhanced by challenging the structural dependence of politics on religious phenomena.

Philosophy in the 20th century witnessed a schism between so called ‘analytic’ and ‘continental’ schools of philosophy. One of the aims of the IJPS from its inception was to provide a space for articles attempting to overcome, or at least foreshorten, that divide. This paper critically examines the various understandings of the divide and takes a quick glance at some of the attempts to bridge it.

The growth of socially responsible investment (SRI) on public financial markets has drawn considerable academic attention over the last decade. Discarding from the previous literature, this article sets up to analyze the Private Equity channel, which is shown to have the potentiality to foster sustainable practices in unlisted companies. The fast integration of the environmental, social and governance issues by mainstream Private Equity investors is unveiled and appears to have benefited from the maturation of SRI on public financial markets and (...) the impetus of large conventional actors. Hypotheses on the characteristics and drivers of this movement are proposed and tested on a unique database covering the French Private Equity industry in 2011. Empirical findings support that Private Equity socially responsible investing is characterized by investor engagement and strategically driven by a need for new value creation sources, increased risk management and differentiation. In particular, results show that independent funds, which need to attract investors, are more likely than captive funds to develop socially responsible practices. Evolution of the movement and future research paths are proposed. (shrink)

What is it about relativism that justifies, or at least explains, its continued appeal in the face of relentless attacks through the history of philosophy? This paper explores a new answer to this old question, casting the response in metaphilosophical terms. § i introduces the problem. § ii argues that one part of the answer is that some of the well-known defences of relativism take it to be a philosophical stance—that is, a broad perspective or orientation with normative consequences—rather than (...) a doctrine or a thesis. § iii draws attention to an assumption, not always explicitly stated by its proponents, that the relativist stance leads to the cultivation of some key intellectual virtues. Open-mindedness, tolerance, intellectual humility, and curiosity are examples of the intellectual virtues that relativism can foster. § iv argues that the defence of relativism on the basis of the virtues that are assumed to follow from it, at best, is only partially successful. Moreover, there is a range of epistemic vices, resulting from the stance, that undercuts the virtue-based defence presented in § iii. (shrink)

Abstract This paper discusses some recent work on the notion of possibility in Wittgenstein's Tractatus assessed by means of an interpretation of the notion put forward in Cerezo 2005. It argues that the proper way to understand the notion of possibility in the Tractatus must pay equal attention both to the picture theory and the truth-functions theory. From this perspective, through an examination of Peach's proposal (2007) it shows that the role played by the notion of logical space in the (...) determination of sense needs to be emphasized. In addition, the paper considers some consequences of the Tractarian notion of possibility, namely, the strong contingency of the world that it involves, which is revealed by the thinkability of logical space as empty envisaged by Wittgenstein in T 2.013, and also discusses the recent debate between Reinhardt (2005) and Geach (2006) on this issue.

As it emerged from philosophical analyses and cognitive research, most concepts exhibit typicality effects, and resist to the efforts of defining them in terms of necessary and sufficient conditions. This holds also in the case of many medical concepts. This is a problem for the design of computer science ontologies, since knowledge representation formalisms commonly adopted in this field do not allow for the representation of concepts in terms of typical traits. However, the need of representing concepts in terms of (...) typical traits concerns almost every domain of real world knowledge, including medical domains. In particular, in this article we take into account the domain of mental disorders, starting from the DSM-5 descriptions of some specific mental disorders. On this respect, we favor a hybrid approach to the representation of psychiatric concepts, in which ontology oriented formalisms are combined to a geometric representation of knowledge based on conceptual spaces.

The general topic of this paper is the ontological commitment to so-called "fictitious objects", that is, things and characters of fictional stories, like Sherlock Holmes and Pegasus. Discourse about fiction seems to entail an ontological commitment to fictitious entities, a commitment that is often deemed inconsistent with empirical facts. For instance, "Pegasus is a flying horse" seems to entail "There are flying horses" as well as "Pegasus exists" (according to some widely accepted logical principles). I discuss two solutions that have (...) been proposed in the literature. The first one amounts to rejecting sentences like "Pegasus is a flying horse" as false, at least if they are taken at face value. This solution is called the "story operator strategy". It consists in paraphrasing sentences like "Pegasus is a flying horse" by means of the expression "according to a story" such that they are interpreted as an elliptic formulation of, e.g., "According to a story, Pegasus is a flying horse". I spell out the difficulties of the story operator strategy and opt for a realist ontology of fiction. A novel interpretation of the story operator "according to a story" is given, which is not only consistent with but even sheds new light on such a realist ontology. In particular, it is shown how the story operator can be used as a tool to introduce the so-called "modes of predication distinction" (which is an essential ingredient of many realist ontologies of fiction) in a commonsensical way.
