ABSTRACT This paper follows on previous papers which present and evaluate various decision procedures for modal logics. We consider new test sets and systems that have been recently proposed in the literature. This new experimental analysis confirm previous experimental results in showing that SAT based decision procedures, i.e., the procedures built on top of decision procedures for propositional satisfiability, are more efficient than tableau based decision procedures. They also confirm previous evidence of an easy-hard-easy pattern in the satisfiability curve for (...) modal K. Finally, on these tests, SAT based decision procedures are also more efficient than the recently proposed decision procedures based on translation methods. These results contradict some of the claims presented in previous papers by other authors. (shrink)

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

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.

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.

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.

Unter dem Willen versteht man die Fähigkeit eines Akteurs, sich frei und überlegtermaßen Ziele zu setzen sowie sie im Handeln planmäßig und beharrlich zu verfolgen. In diesem Band werden erstmals umfassend die begriffs- und problemgeschichtlichen Entwicklungen innerhalb der verschiedenen Philosophenschulen (Stoa, Neuplatonismus, Peripatetik) sowie in der christlichen Patristik untersucht, die zur Ausbildung eines philosophisch "vollwertigen" Willensbegriffs in der Spätantike geführt haben.

This book concerns the soul/body problem in Plato and Aristotle. Established as well as early career scholars actually working on Plato and Aristotle explore - under different points of view as well as through original readings and interpretations - the manifold dimensions involved in the conception of the soul/body relation articulated by the two greatest founders of Western Thought. The book starts with an exploration of the relation between cause and matter in Plato and Aristotle, then some papers on Plato's (...) theory of soul and body are presented, which involve new advancements in the research about Platonic epistemology, moral and political theory, metaphysics of mind, even about his religious and 'theological' view. Some papers on Aristotle's model follow, which are focused on his so-called "hylomorphism" as an alternative view to Plato's alleged "dualism": the ontology of the soul/body relation in Aristotle is explored, as well as the implications of this theoretical framework for his theory of knowledge, his moral theory, his cognitive psychology. Finally, two papers critically assess the philosophical connections between Aristotle's hylomorphism and its modern and contemporary Wirkungsgeschichte. (shrink)

The work of contemporary Italian thinkers, what Roberto Esposito refers to as Italian Theory, is attracting increasing attention around the world. This book explores the reasons for its growing popularity, its distinguishing traits, and why people are turning to these authors for answers to real-world issues and problems. The approach he takes, in line with the keen historical consciousness of Italian thinkers themselves, is a historical one. He offers insights into the great "unphilosophical" philosophers of life—poets, painters, politicians and (...) revolutionaries, film-makers and literary critics—who have made Italian thought, from its beginnings, an "impure" thought. People like Machiavelli, Croce, Gentile, and Gramsci were all compelled to fulfill important political roles in the societies of their times. No wonder they felt that the abstract vocabulary and concepts of pure philosophy were inadequate to express themselves. Similarly, artists such as Dante, Leonardo Da Vinci, Leopardi, or Pasolini all had to turn to other disciplines outside philosophy in order to discuss and grapple with the messy, constantly changing realities of their lives. For this very reason, says Esposito, because Italian thinkers have always been deeply engaged with the concrete reality of life and because they have looked for the answers of today in the origins of their own historical roots, Italian theory is a "living thought." Hence the relevance or actuality that it holds for us today. Continuing in this tradition, the work of Roberto Esposito is distinguished by its interdisciplinary breadth. In this book, he passes effortlessly from literary criticism to art history, through political history and philosophy, in an expository style that welcomes non-philosophers to engage in the most pressing problems of our times. As in all his works, Esposito is inclusive rather than exclusive; in being so, he celebrates the affirmative potency of life. (shrink)

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.

What is the relationship between persons and things? And how does the body transform this relationship? In this highly original new book, Roberto Esposito - one of Italy’s leading political philosophers - considers these questions and shows that starting from the body, rather than from the thing or the person, can help us to reconsider the status of both. Ever since its beginnings, our civilization has been based on a strict, unequivocal distinction between persons and things, founded on the (...) instrumental domination of persons over things. This opposition arose out of ancient Roman law and persisted throughout modernity, to take its place in our current global market, where it continues to generate growing contradictions. Although the distinction seems to appear clear and necessary to us, what we are continually witnessing in legal, economic, and technological practice is a reversal of perspectives: some categories of persons are becoming assimilated with things, while some types of things are taking on a personal profile. With his customary rigour, Roberto Esposito argues that there exists an escape route out of this paradox, constituted by a new point of view founded in the body. Neither a person nor a thing, the human body becomes the decisive element in rethinking the concepts and values that govern our philosophical, legal, and political lexicons. (shrink)

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.

The possibility of changing the past by means of time-travel appears to depend on the possibility of distinguishing the past as it is ‘before’ and ‘after’ the time-travel. So far, all the metaphysical models that have been proposed to account for the possibility of past-changing time-travels operate this distinction by conceiving of time as multi-dimensional, and thus by significantly inflating our metaphysics of time. The aim of this article is to argue that there is an intuitive sense in which past-changing (...) time-travels are metaphysically possible also in one-dimensional time. (shrink)

Underscoring the economic significance of the Knightian distinction between risk and uncertainty, Don Katzner forcefully challenges the continued dominance of the expected utility model based on subjective probability in macroeconomic analysis and offers in its place a simple yet elegant model of decision making inspired by the pioneering work of G.L.S. Shackle. In doing so, Katzner lends support to a research program to identify a more coherent and empirically grounded theory of decision making under uncertainty. Our paper makes three contributions (...) to this program. First, we argue that the appropriate choice of a model of individual behavior under uncertainty cannot be adjudicated merely on logical, a priori grounds, but must ultimately be based on consistency with observed behavior. There are many internally consistent models and their external conditions of validity hardly ever rely on inconceivable scenarios. Second, while Katzner’s model certainly provides a plausible foundation for understanding choice under uncertainty, we suggest that it is somewhat underdetermined. It requires further theoretical articulation to yield testable predictions which differentiate it from competing approaches. Third, we discuss recent experimental findings that may need to be addressed by any satisfactory theoretical account of decision making under uncertainty. (shrink)

The topic of the present reflection is Christian religious belief. Specifically, we will use Husserlian tools in order to examine the positional nature of this particular type of belief. We will be less interested in the question concerning the success conditions of this experience and more in its noetic structure. According to our proposal, to believe by faith supposes (although it is not exhausted by) accepting the existence of mundane evidence speaking against this fundamental belief. The believer acknowledges the existence (...) of this contradicting en-doxical basis and nevertheless believes what she believes. We will refer to this simultaneous movement of accepting and cancelling as the concessive structure of the religious attitude. The para-doxical movement of experiencing conflicting evidence as being subjectively ineffective is a key component of this attitude. At least some inchoative conflict with the world is required in order for the religious belief to be religious. Lastly, we will try to show that, with a distinctive terminology, the idea that the Christian religious attitude involves a conflict between subjectivity and world is present not only in Kierkegaard but also in phenomenological figures like Scheler and even Husserl.

This chapter shows how The Daily Show targets those political and religious leaders who claim to receive clear revelations from the divine, either by their own particular religious experiences and practices or through sacred texts. It considers some of the ways Stewart calls into question their apparently unquestionable grasp of the mind of God. Philosophers like the famous English thinker John Locke have made their living by carefully examining not only the nature of the world around us, but also the (...) more puzzling aspects of human behavior. For instance, Locke describes and critiques the sort of “enthusiasm” by recognizing that such religiously convicted individuals: “persuade themselves that they are under the peculiar guidance of heaven in their actions and opinions, especially in those of them which they cannot account for by the ordinary methods of knowledge and principles of reason.

In this paper I take a sceptical view of the standard cosmological model and its variants, mainly on the following grounds: (i) The method of mathematical modelling that characterises modern natural philosophy-as opposed to Aristotle's-goes well with the analytic, piecemeal approach to physical phenomena adopted by Galileo, Newton and their followers, but it is hardly suited for application to the whole world. (ii) Einstein's first cosmological model (1917) was not prompted by the intimations of experience but by a desire to (...) satisfy Mach's Principle. (iii) The standard cosmological model-a Friedmann-Lematre-Robertson-Walker spacetime expanding with or without end from an initial singularity-is supported by the phenomena of redshifted light from distant sources and very nearly isotropic thermal background radiation provided that two mutually inconsistent physical theories are jointly brought to bear on these phenomena, viz the quantum theory of elementary particles and Einstein's theory of gravity. (iv) While the former is certainly corroborated by high-energy experiments conducted under conditions allegedly similar to those prevailing in the early world, precise tests of the latter involve applications of the Schwarzschild solution or the PPN formalism for which there is no room in a Friedmann-Lematre-Robertson-Walker spacetime.

Octavio Paz: Ontology and Surrealism discusses poet Octavio Paz (1914-1998), one of Mexico's most controversial intellectuals. Over several decades, Paz has been celebrated for his impact on literature and culture as a poet as well as an essayist, and he is recognized as a great thinker and as a student of German ontology and phenomenology. Roberto Sanchez Benitez analyzes in detail Paz's training within the European philosophical thinking of the twentieth century, as well as in the artistic avant-garde, to (...) illustrate the way in which philosophical, anthropological, linguistic, sociological, literary, and artistic proposals enriched his work and Mexican culture during the post-revolutionary period. Sanchez Benitez posits that Paz moved from a phenomenological ontology to a historicism of the human condition, wherein morality, politics, and the arts all reside in an ideological context where dogmatisms where impose in the face of a lack of internal criticism. This book explores the themes of the poetic act that Paz associated with his ontological and surrealist readings, leading up to when they were transformed by his experience in India and the assimilation of Eastern philosophies, along with going through a set of Western proposals relating to love, eroticism, and art. Scholars of literature, philosophy, Latin American Studies, and history will find this book particularly useful. (shrink)

‘Gnosticism and Modern Nihilism’ (published in Social Research , 1952) is indeed one of Hans Jonas’ most famous essays, to which its author reserved very deep attention during his philosophical career. As a former pupil of Martin Heidegger and Rudolf Bultmann, Jonas started to deal with religious topics, and specifically with Gnosticism, from the very outset of his philosophical career in the 1920s. After gaining recognition thanks to his remarkable philosophical-existential interpretation of Gnosticism, he returned to the modern age and (...) its philosophical characters. Principally, Jonas discovered that modern philosophy up to Heidegger and Sartre suffered from a peculiar spiritual disease – namely, nihilism – that he had already traced in ancient Gnosticism and that he intended to reject. Therefore, Jonas’ acquaintance with ancient religion and thinking gave him a deep insight into the modern age and provided him with a first glimpse of what was later to become his biological philosophy. However, whoever could imagine that the idea of tracing similarities between Gnosticism and modern thinking came to Jonas at the beginning of 1950 from the famous philosopher and biologist Ludwig von Bertalanffy? In this article, I shall endeavour to demonstrate this thesis by quoting from unpublished documents. However, I shall also try to prove that Jonas did not follow von Bertalanffy’s advice completely. The overall aim is, therefore, both to highlight the origins of an essential turning point in the thinking of Hans Jonas, and, on such a basis, to outline the innovation and originality of his philosophical contribution.

This paper investigates the relationship between Stakeholder Engagement (SE) and Corporate Social Responsibility (CSR), approaching CSR as a complex system made up of components and interactions. Adopting a System Thinking approach to analyze CSR in a stakeholders-company network, explorative research is conducted through three stages: (1) a critical literature review aimed to identify the components of the CSR system model, (2) the development of the dataset and of the Causal Loop Diagram (CLD) model, (3) the analysis of the CSR behavior (...) in light of the ‘system archetypes’ underpinning the system. The analysis reveals both the structure and the dynamics of CSR and explain its behavior in light of the stakeholder engagement network variables. Findings from this research underscore the existence of six feedback loops, which characterize the relation CSR-SE. The ‘company-stakeholder fit’ acts as a growth engine for the stakeholder engagement network, however other balancing dynamics (e.g., detriment of business objectives) require a tradeoff between Social and Business orientation. This paper contributes to a more profound understanding of the relation between CSR and stakeholder engagement, showing in particular the link between CSR and SE under the assumption of stakeholder-company network. The insights provided serve as a guide for managers and policymakers to navigate the complex dynamics of SE to inform effective strategies of CSR based on network structural actions. (shrink)

General knowledge of the role of vitamin D3 in human physiology has been shaped by its discovery as a preventive agent of nutritional rickets, a defect in bone development due to inadequate uptake of dietary calcium. Studies on the function of the hormonal form of vitamin D3, 1α,25‐dihydroxyvitamin D3, have been greatly accelerated by the molecular cloning and structural analysis of the vitamin D3 receptor, which is a ligand‐activated regulator of gene transcription. Molecular genetic techniques including genomics have helped reveal (...) that 1α,25‐dihydroxyvitamin D3 can control more than calcium homeostasis. It has widespread effects on cellular differentiation and proliferation, and can modulate immune responsiveness, and central nervous system function. Moreover, accumulating epidemiological and molecular evidence suggests that 1α,25‐dihydroxyvitamin D3 acts as a chemopreventive agent against several malignancies including cancers of the prostate and colon. Here, we survey the most‐recent findings and discuss their implications for the potential therapeutic uses of vitamin D analogues. BioEssays 26:21–28, 2004. © 2003 Wiley Periodicals, Inc. (shrink)

En el presente trabajo nos hemos propuesto la factura de una exposición sucinta en torno a la crítica contra la metafísica clásica desde la perspectiva de Eduardo Nicol. Puede decirse que, desde el punto de vista de nuestro autor, la característica básica de la metafísica ha consistido en el soterramiento del ser, es decir, la metafísica clásica, de alguna u otra manera, ha versado acerca de un ser atemporal y oculto. El ocultamiento del ser ha estado íntimamente ligado al olvido (...) del tiempo y al endiosamiento de la razón; justo por esto Nicol se propone ahora una recuperación de la visibilidad del ser en aras de un contradiscurso del método.

Un primer aspecto concierne a la praxis no-intencional y primaria del cuerpo propio. A ello se añade su condición de sostén para los valores sensibles de la comodidad y la salud, y de trampolín para valores espirituales cuyo nivel superior se encuentra en los valores éticos de la persona. Estos puntos de vista husserlianos encuentran nuevos desarrollos en la fenomenología: M. Henry pone el acento en un "yo puedo" pre-intencional, y Ricoeur describe el cuerpo propio como "fuente" de valores propios (...) y "resonador afectivo" de todos los valores, y a la vez esboza una concepción de la felicidad que incluye temples particulares de la corporalidad. Por último, Husserl considera la ofrenda del cuerpo propio a los valores espirituales en el sacrificio como la afirmación positiva de la vida de la humanidad. J. Patocka y E. Lévinas han desarrollado esta línea de pensamiento. A first aspect has to do with the non-intentional and primal praxis of the living body. To this is added its status as a support for the sensuous values of comfort and health and a springboard for spiritual values, the highest level of which lies in the ethical values of the person. These Husserlian views find new developments in phe-nomenology: M. Henry highlights a pre-intentional "I can", M. Scheler analyzes the relationship between hedonistic, vital, and spiritual values, and P. Ricoeur describes the living body both as the "source" ofits own proper values and the "affective resonator" of all values, and also outlines a view on happiness that encompasses particular bodily attunements. Finally, Husserl considers the offering of the living body to spiritual values in sacrifice as the positive assertion of humankind's life. J. Patocka and E. Lévinas have developed this line of thought. (shrink)
