This high-level study discusses Newtonian principles and 19th-century views on electrodynamics and the aether. Additional topics include Einstein's electrodynamics of moving bodies, Minkowski spacetime, gravitational geometry, time and causality, and other subjects. Highlights include a rich exposition of the elements of the special and general theories of relativity.

This paper is concerned with certain ontological issues in the foundations of geographic representation. It sets out what these basic issues are, describes the tools needed to deal with them, and draws some implications for a general theory of spatial representation. Our approach has ramifications in the domains of mereology, topology, and the theory of location, and the question of the interaction of these three domains within a unified spatial representation theory is addressed. In the final part we also consider (...) the idea of non-standard geographies, which may be associated with geography under a classical conception in the same sense in which non-standard logics are associated with classical logic.

Volume 1 of Politics, a work in constructive social theory. Newly available, the complete work of Politicsa program for a comprehensive progressive alternative to the dominant ideologies of social democracy and neo-liberalismfrom one of the worlds leading social and political thinkers. False necessity is the central theme in the three-volume series Politics. It presents both a way of explaining society and a program for changing it. The explanation develops a radical alternative to Marxism, showing how we can account for established (...) social arrangements without denying their contingency or our freedom. The program offers a progressive alternative to the now-dominant ideological conceptions of neoliberalism and social democracy: a set of institutional innovations that would democratize markets, deepen democracy and empower individuals. For this new edition, Unger has written a comprehensive introduction that explores the limits of our understanding of society and our practice of politics, and reconsiders proposals contained in the book as special cases of a larger family of untried political possibilities.

El autor analiza algunos aspectos de los debates sobre la democracia en la llamada transición de los años ̓80, para advertir sobre la preeminencia que adquirieron las disposiciones procedimentales y representativas —elevadas a condición metanormativa— y la conceptualización de la política como producción de consensos. Esas orientaciones impidieron una recuperación de las experiencias democráticas que la dictadura intentó cancelar, y fueron incapaces de poner en foco las figuras de subjetividad que el terror estatal y el neoliberalismo produjeron en tanto intervenciones (...) sobre las tramas sociales. Finalmente, el autor se detiene brevemente en algunas experiencias políticas democratizadoras, en tanto formas de aparición de los pueblos en estos últimos 40 años. (shrink)

Husserl proceeds to show how a world-representation emerges from our world-experience, and how an idea of the world plays a role in the expansion of world-representations. He also draws our attention to the appropriation of other world-representations in a process of adjustment and compensation leading to intersubjective world-representations, and offers an analysis of the status of world-representations within transcendental phenomenology. In this article I will underline the relevance of Husserl’s concept of horizonedness to the characterization of the three levels of (...) world-experience, worldrepresentation, and the world as an idea. In getting clear on this relevance several points must be emphasized. (shrink)

"A pleasure to read. Gracefully written by a scholar well grounded in the relevant philosophical, historical, and technical background. . . . a helpfully clarifying review and analysis of some issues of importance to recent philosophy of science and a source of some illuminating insights."--Burke Townsend, Philosophy of Science.

According to a leading view, emotions such as admiration, contempt, pride, and shame are important vehicles of agential development. Through admiration and contempt, we establish models and countermodels against which to shape our character; through pride and shame, we get a sense of how we measure up to them. Critics of this view object that these emotions always deliver uncompromising evaluations: admiration casts people in a completely positive light, while contempt casts aspersion on them. Therefore, insofar as they lack the (...) capacity for nuance, these emotions are systematically unfitting and misleading. This paper discusses this objection as originally formulated by John Doris as well as Macalester Bell’s response. Drawing from research on emotional intentionality, it will be argued that Doris’ and Bell’s accounts are respectively misguided criticisms and inadequate defences of these emotions. Their mistake lies in an invalid transition from the claim that these emotions are intentionally directed towards persons to the claim that they deliver global evaluations of those towards whom they are directed. By rejecting this inference, it will be shown that these emotions can deliver nuanced and fitting evaluations in a way Doris’ objection overlooks and Bell’s response precludes us from articulating.

Ontology engineering is a hard and error-prone task, in which small changes may lead to errors, or even produce an inconsistent ontology. As ontologies grow in size, the need for automated methods for repairing inconsistencies while preserving as much of the original knowledge as possible increases. Most previous approaches to this task are based on removing a few axioms from the ontology to regain consistency. We propose a new method based on weakening these axioms to make them less restrictive, employing (...) the use of refinement operators. We introduce the theoretical framework for weakening DL ontologies, propose algorithms to repair ontologies based on the framework, and provide an analysis of the computational complexity. Through an empirical analysis made over real-life ontologies, we show that our approach preserves significantly more of the original knowledge of the ontology than removing axioms. (shrink)

That emotions are especially valuable for our well-being has become a widely agreed upon claim. In this article, we argue that many of the ways in which the emotions are commonly considered to be prudentially valuable – hedonically, experientially, and adaptively – are not specific to the emotions: they are in fact shared by other affective reactions such as drives and sensory affects. This may suggest that emotions are not prudentially valuable in any distinctive manner. We challenge this suggestion by (...) arguing that, unlike other affective reactions, emotions provide unique contexts in which to refine our general sensibility to a wide variety of evaluative properties – and that in this sense they are prudentially valuable in a distinctive way.

Roberto Esposito is one of the most prolific and important exponents of contemporary Italian political theory.

As the worlds of economics, politics, culture, and communications face a growing wave of globalization that will likely continue, ethical challenges for journalists have also gone global. I propose a clear division between ethics codes for media owners, the public, and professional journalists and present a set of considerations and specific rules applicable only to the last group. In this article I advocate a universal code of journalistic ethics but point out problems and warn against dangers that have made the (...) application of such codes difficult in the past. A universal code should consider the voluntary nature of such an endeavor, the cultural and economic differences in various journalistic traditions, and the problem of producing solutions acceptable to all involved.

This book by Roberto Esposito - a leading Italian political philosopher - is a highly original exploration of the relationship between human bodies and societies. The original function of law, even before it was codified, was to preserve peaceful cohabitation between people who were exposed to the risk of destructive conflict. Just as the human body's immune system protects the organism from deadly incursions by viruses and other threats, law also ensures the survival of the community in a life-threatening (...) situation. It protects and prolongs life. But the function of law as a form of immunization points to a more disturbing consideration. Like the individual body, the collective body can be immunized from the perceived danger only by allowing a little of what threatens it to enter its protective boundaries. This means that in order to escape the clutches of death, life is forced to incorporate within itself the lethal principle. Starting from this reflection on the nature of immunization, Esposito offers a wide-ranging analysis of contemporary biopolitics. Never more than at present has the demand for immunization come to characterize all aspects of our existence. The more we feel at risk of being infiltrated and infected by foreign elements, the more the life of the individual and society closes off within its protective boundaries, forcing us to choose between a self-destructive outcome and a more radical alternative based on a new conception of community.

Reasons-first theorists claim that facts about reasons for attitudes are normatively primitive, and that all other normative facts ultimately reduce to facts about reasons. According to their view, for example, the fact that something is good ultimately reduces to facts about reasons to favour it. I argue that these theories face a challenging dilemma due to the normativity of arational lifeforms, for instance the fact that water is good for plants. If all normative facts are, ultimately, facts about reasons for (...) attitudes, then reasons-first theorists must either (a) show that these facts do reduce to facts about reasons, or (b) concede that they do not and, instead, show that this is not a problem for their view. Both options, however, are riddled with difficulties—or so I will try to argue. (shrink)

Adequate knowledge about Buddhism is essential to the education and culture of any person who does not want to be simply another alienated member of a herd that walks blindly amid a technological revolution. It is possible to understand early Buddhism through modern language and knowledge and establish its relations with contemporary thought and its references. With this, it becomes possible to deepen and broaden our perception of these millennial principles' compatibility with our modern ways of living and knowing. The (...) study required for this is quite laborious. Buddhism is the subject underlying a gigantic literary and cultural mountain. The closer we get to its original concept, the deeper and more voluminous the excavation we have to do. (shrink)

This unique textbook states and proves all the major theorems of many-valued propositional logic and provides the reader with the most recent developments and trends, including applications to adaptive error-correcting binary search. The book is suitable for self-study, making the basic tools of many-valued logic accessible to students and scientists with a basic mathematical knowledge who are interested in the mathematical treatment of uncertain information. Stressing the interplay between algebra and logic, the book contains material never before published, such as (...) a simple proof of the completeness theorem and of the equivalence between Chang's MV algebras and Abelian lattice-ordered groups with unit - a necessary prerequisite for the incorporation of a genuine addition operation into fuzzy logic. Readers interested in fuzzy control are provided with a rich deductive system in which one can define fuzzy partitions, just as Boolean partitions can be defined and computed in classical logic. Detailed bibliographic remarks at the end of each chapter and an extensive bibliography lead the reader on to further specialised topics. (shrink)

This paper presents a semantical analysis of the Weak Kleene Logics Kw3 and PWK from the tradition of Bochvar and Halldén. These are three-valued logics in which a formula takes the third value if at least one of its components does. The paper establishes two main results: a characterisation result for the relation of logical con- sequence in PWK – that is, we individuate necessary and sufficient conditions for a set.

This article addresses some useful coordinates for the analysis of the relationship between philosophy and taxation. My argument aims to show the relevance of a philosophy of taxation and thus draw attention to civic education required to shape a democratic public reason, truthful, critical and attentive. I emphasize the character of “donation” that is the rule of law within a democratic constitutional regime, which depends on tax payments for the purposes proposed, and particularly those of a social distributive justice. I (...) distinguish between charity and justice and political obligation to maintain that by implementing an effective "rule of law" citizens “donate” ourselves mechanisms and procedures for advancing a system of justice as fairness. This grant does not pertain to the field of natural duties, charity or sacrifice of supererogatory acts, but is expressed in institutional programs whose implementation and maintenance required from us pay taxes, but always based on personal commitment. Thus, close to John Rawls I emphasize the value of freedom. (shrink)

Roberto Esposito is one of leading figures in a new generation of Italian philosophers. This book criticizes the notion of the person and develops an original account of the concept of the impersonal - what he calls the third person.

In this article, Roberto Esposito lays out the genealogical pathways linking the three major concepts around which his most recent work has wound its way: community, immunity, and biopolitics. Although immunity is necessary to the preservation of our life, when driven beyond a certain threshold it forces life into a sort of cage where not only our freedom gets lost but also the very meaning of our existence – that opening of existence outside itself that takes the name of (...) communitas. A hermeneutics informed by immunity can allow the category of community to regain a new political significance, without ending up in a substantialist metaphysics. This task is dictated by the urgent need for an affirmative biopolitics – a horizon of meaning – in which life would no longer be the object but somehow the subject of politics. But what sort of shape would this take? Where would we trace its symptoms? And with what objectives? A preliminary answer focuses on breaking the vise grip between public and private that threatens to crush the common, by seeking instead to expand the space of the common, in the fight, for example, against the planned privatization of water and the battle over energy sources.

A wide family of many-valued logics—for instance, those based on the weak Kleene algebra—includes a non-classical truth-value that is ‘contaminating’ in the sense that whenever the value is assigned to a formula φ⁠, any complex formula in which φ appears is assigned that value as well. In such systems, the contaminating value enjoys a wide range of interpretations, suggesting scenarios in which more than one of these interpretations are called for. This calls for an evaluation of systems with multiple contaminating (...) values. In this paper, we consider the countably infinite family of multiple-conclusion consequence relations in which classical logic is enriched with one or more contaminating values whose behavior is determined by a linear ordering between them. We consider some motivations and applications for such systems and provide general characterizations for all consequence relations in this family. Finally, we provide sequent calculi for a pair of four-valued logics including two linearly ordered contaminating values before defining two-sided sequent calculi corresponding to each of the infinite family of many-valued logics studied in this paper.

This paper discusses three relevant logics that obey Component Homogeneity - a principle that Goddard and Routley introduce in their project of a logic of significance. The paper establishes two main results. First, it establishes a general characterization result for two families of logic that obey Component Homogeneity - that is, we provide a set of necessary and sufficient conditions for their consequence relations. From this, we derive characterization results for S*fde, dS*fde, crossS*fde. Second, the paper establishes complete sequent calculi (...) for S*fde, dS*fde, crossS*fde. Among the other accomplishments of the paper, we generalize the semantics from Bochvar, Hallden, Deutsch and Daniels, we provide a general recipe to define containment logics, we explore the single-premise/single-conclusion fragment of S*fde, dS*fde, crossS*fdeand the connections between crossS*fde and the logic Eq of equality by Epstein. Also, we present S*fde as a relevant logic of meaninglessness that follows the main philosophical tenets of Goddard and Routley, and we briefly examine three further systems that are closely related to our main logics. Finally, we discuss Routley's criticism to containment logic in light of our results, and overview some open issues. (shrink)
