An attempt is made to recognize the coherence of Suárez's political postulates and his anthropology. For this purpose I translate a selection of texts, mainly from the third Book of the De opere sex dierum, which gives testimony of the foundations that reveal not only indications of a thought pre-illustrated in Suárez, but the relevance of topics found in his writings that remain to be explored in any of its volumes. I have divided this work into two sections: The first (...) makes brief mention of the defense of the equality of the sexes in François Poullain de la Barre. Furthermore, it refers to the political virtue of Descartes and his defense of the difference of the sexes. The crucial section exhibits forgotten arguments from Suárez's treatise De opere sex dierum, where the question of the equality of the sexes is addressed. (shrink)

Este estudio se propone destacar los resultados ofrecidos en la edición crítica y traducción portuguesa del libro De Legibus Uvm I Da Ley em Geral de F. Suárez, a cargo del mancomunado esfuerzo de investigadores lusos contemporáneos, quienes examinaron esa Obra de jurisprudencia nacida de las lecciones que F. Suárez diera desde 1601-3 y que plasmara en la edición original del tratado de Coimbra en 1612. Subrayo aspectos de la doctrina política que dejarán al descubierto un Suárez plura novavit, influyente (...) en la conformación moderna de la republica democrática. This paper calis the attention on the outcome of the research offered in the critical edition and Portuguese translation of the book De Legibus Livro I Da Ley em Geral de F. Suárez, done by the joint effort of contemporary Researchers, who examined that work of jurisprudence born of the lectures that Suarez gave around 1601-3, and that resulted in the original 1612 edition of the Coimbra treatise. I underline aspects of the political doctrine, which exposes a plura novavit-Suarez that promote a new form of the political regimes and influence in the shaping of the modern democratic republic.

Al final del Libro II del An Essay Concerning Human Understanding, Locke manifiesta que «hay una relación tan íntima entre las ideas y las palabras […] que es imposible hablar clara y distintamente de nuestro conocimiento, que consiste completamente en proposiciones, sin considerar, primero, la naturaleza, uso y significación del lenguaje». De varias y diversas maneras Locke insiste en la tesis que ‘las palabras significan ideas’. En este ensayo me propongo: 1º resumir la teoría general del lenguaje de Locke; 2º (...) revisar algunas objeciones regulares a esta teoría, y 3º intentar una explicación de lo que Locke quiere decir cuando enuncia que ‘las palabras significan ideas’. Con respecto a este punto mostraré, apoyando la interpretación de E. J. Ashworth, que en su tesis semántica Locke usa el vocablo ‘significar’ (‘signifying’) no del modo como es usado por los teóricos contemporáneos del siglo XX, sino en el sentido que algunos escolásticos usaron el término ‘significare’. At the very end of Book II of ‘An Essay Concerning Human Understanding’, Locke finds out «that there is so close a connexion between Ideas and Words […] that it is impossible to speak clearly and distinctly of our Knowledge, which all consists in Propositions, without considering first the Nature, Use, and Signification of Language». In various and diverse ways Locke defends the thesis that ‘Words signify Ideas’. My aim in this paper is first, to sum up Locke’s general theory of Language; secondly, to revisit some regular objections concerning this theory, and thirdly, to intend an explanation of what Locke means when he points out that ‘Words signify ideas’. In regard to this point, I shall hold up E. J. Ashworth’s interpretation to show that Locke semantic thesis involves the use of the verb ‘to signify’ (‘signifying’) not in the manner that it is used by contemporary theorists of the twentieth century, but in the sense that some scholastics used the term ‘significare’.

Suárez y la Filosofía Moderna Resumen: Los intérpretes de hoy debaten sobre el estatuto y la asociación de Francisco Suárez con la Filosofía Moderna. Este estudio enfoca los principales aspectos de la filosofía especulativa y práctica del pensador jesuita, con el propósito de mostrar que, en las diversas disciplinas abordadas, Suárez ha tomado en cuenta genealógicamente, la formalización de las teorías precedentes: las ha re-formulado en términos metodológicos para progresar. A su preferencia parcial por pruebas a priori, agrega datos de (...) experiencia con respecto a los postulados de la metafísica. Por otra parte, innova en la adopción del lenguaje médico imperante en materias de psicología moral y en la intrincación de las disciplinas teológicas y jurídica, en materias políticas. Con este proceder, que se distingue del estrictamente propedéutico para la investigación científica, alcanza una comprensión adecuada de los fenómenos y, a partir de sus replanteamientos establece el curso de figuras representativas del pensamiento moderno. Palabras clave: Suárez; ontologia; epistemologia; psicología moral; filosofía política; filosofía moderna. Suárez and Modern Philosophy Abstract: Today's interpreters debate the status and association of Francisco Suárez with Modern Philosophy. This paper focuses on the main aspects of the speculative and practical philosophy of the Jesuit thinker, with the purpose of showing that, in the various disciplines approached, Suárez has taken into account genealogically the formalization of the preceding theories: he has reformulated them in methodological terms to progress. To his partial preference for a priori proofs, he adds data of experience regarding the postulates of metaphysics. On the other hand, he innovates in the adoption of the prevailing medical language in matters of moral psychology and in the intricacy of theological and legal disciplines, in political matters. With this procedure, which differs from the strictly propaedeutic for scientific research, he reaches an adequate understanding of the phenomena and, from the rethinking of it, establishes the course of representative figures of modern thought. Key-words: Suárez; ontology; epistemology; moral psicology; political philosophy; Modern philosophy.

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

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)

In this article Roberto Balzani, the mayor of Forlì, remembers Roberto Ruffilli, 25 years after his murder. The remembrance reconstructs the steps of his academic career and of his political commitment. Ruffilli graduated at the Catholic University of Milan; his researches in contemporary history placed him in an original position if compared with the Italian studies of the time. The constant attention towards the history of administration and the transformations of the state is the basis on which Ruffilli (...) built his proposals concerning the reform of the insitutional and political system. Balzani concludes the article by affirming that the problems of today aren't any different, that is why Ruffilli's proposals still demonstrate their modernity. (shrink)

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.

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)

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.

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.

A discussion with Roberto Andorno about global bioethics and biolaw, the Coronavirus pandemic, and its impact on human dignity and rights. Can we foresee the emerging new profile of global bioethics and biolaw in the post-Coronavirus era? How significant are they going to be in the future, after the enormous pressure that the Coronavirus pandemic has exercised on key political, legal, and ethical values? Must the voice of bioethicists -compared to the ‘hard’ scientific data- be louder in the future (...) concerning decisions about emergency social and medical measures? Is there a hope that public empowerment will support robust, global public engagement and meaningful deliberation? How much does Roberto Andorno’s view on human dignity reveal a supposed commitment to moral realism? The massive deaths of elderly people living in hospices of Sweden, Spain, and Italy, based on an implicit ‘fair innings’ view, has recently posed certain questions on the moral unacceptability of such practices. The same questions arise in the case of the legalization of euthanasia grounded on the implicit acceptance of the view that life is not worth living under certain circumstances. Is it possible that the human rights bodies worldwide will acquire executive power, and how could this become possible? How influential the ‘precautionary principle’ can become regarding clinical and research ethics in the future? How urgent is the importance of the introduction of bioethical education in the curricula of ‘hard’ empirical studies? Roberto Andorno discusses with us all these controversial and under heated public debate issues, giving sometimes provocative answers. (shrink)

Holes are a good example of the sort of entity that down-to-earth philosophers would be inclined to expel from their ontological inventory. In this work we argue instead in favor of their existence and explore the consequences of this liberality—odd as they might appear. We examine the ontology of holes, their geometry, their part-whole relations, their identity and their causal role, the ways we perceive them. We distinguish three basic kinds of holes: blind hollows, perforating tunnels, and internal cavities, treating (...) these uniformly as immaterial bodies. We develop a morphology of holes, focusing on the way a hole can be filled, and then look at the main properties of the resulting conceptual framework: holes are parasitic upon the surfaces of their hosts; holes can move, fuse into each other, split; they can be born, develop, and die. Finally, we examine how some morphological features of holes are represented in perception, including the conditions whereby we have the impression that we see, feel, or even hear a hole. The book has over 150 pictures and is completed by a formal appendix, a section with puzzles and exercises, and a extensive annotated bibliography. (shrink)

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.

Introduction : nothing in common -- Fear -- Guilt -- Law -- Ecstasy -- Experience -- Appendix : nihilism and community.

This paper argues that some of the misunderstandings surrounding the meaning and function of the concept of human dignity in bioethics arise from a lack of distinction between two different roles that this notion plays: one as an overarching policy principle, and the other as a moral standard of patient care. While the former is a very general concept which fulfils a foundational and a guiding role of the normative framework governing biomedical issues, the latter reflects a much more concrete (...) and context-specific understanding of the patient as a “person”. The importance of dignity as a policy principle will be described by appealing to the distinction between principles and rules as developed by some legal philosophers. The value of dignity as a standard of patient care will be illustrated with the help of concrete examples and by drawing on the taxonomies of dignity proposed by Jonathan Mann and other scholars. The overall scope of the article is to highlight this double and complementary role of human dignity in bioethics. (shrink)

This article discusses the controversy between Schelling and Eschenmayer regarding the Freiheitsschrift of 1809. Eschenmayer, a follower of the ideas of Jacobi, accuses Schelling of degrading God in applying to Him human concepts. Schelling, on the contrary, thinks that the faith needs the understanding.

I present an argument proving that there are no fundamental facts, which is similar to an argument recently presented by Mark Jago for truthmaker maximalism. I suggest that this argument gives us at least some prima facie, defeasible reason to believe that there are no fundamental facts.

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.

ABSTRACT The philosophical tradition approaches to morals have their grounds predominantly on metaphysical and theological concepts and theories. Among the traditional ethics concepts, the most prominent is the Divine Command Theory (DCT). As per the DCT, God gives moral foundations to the humankind by its creation and through Revelation. Morality and Divinity are inseparable since the most remote civilization. These concepts submerge in a theological framework and are largely accepted by most followers of the three Abrahamic traditions: Judaism, Christianity, and (...) Islam: the greatest part of the human population. Holding faith and Revelation for its grounds, the Divine Command Theories are not strictly subject to the demonstration. The opponents to the Divine Command conception of morals, grounded in the impossibility of demonstration of its metaphysical and religious assumptions, have tried for many centuries (albeit unsuccessfully) to devalue its importance. They held the argument that it does not show material evidence and logical coherence and, for this reason, cannot be taken into account for scientific nor philosophical purposes. It is just a belief and, as so, should be understood. Besides these extreme oppositions, many other concepts contravene the Divine Command theories, in one or another way, in part or in full. Many philosophers and social scientists, from the classic Greek philosophy up to the present date, for instance, sustain that morality is only a construct, and thus culturally relative and culturally determined. However, this brings many other discussions and imposes the challenge to determine what is the meaning of culture, which elements of culture are morally determinant, and finally, what are the boundaries of such relativity. Moral determinists claim that everything related to human behavior, including morality, is determined, once free will does not exist. More recently, modern thinkers argued that there is a strict science of morality. However, the scientific method alone, despite explaining several facts and evidence, cannot enlighten the entire content and full meaning of ethics. Morals’ understanding requires a broader perception, and an agreement among philosophers, which they have never achieved. All of these questions have many different configurations depending on each philosophical strand, and start complex analysis and endless debates, as long as many of them are reciprocally conflictive. The universe and the atmosphere involving this thesis are the dominions of all these conceptual conflicts, observed from an objective and evolutionary standpoint. Irrespective of this circumstance and its intrinsic importance, however, these questions are far distant from the methodological approach of an analytical discussion on objective morals, what is, indeed, the aim and scope of this work. We should briefly revisit these prominent traditional theories because this thesis shelters a comparative study, and its assumptions at least differ profoundly from all traditional theories. Therefore, it becomes necessary offering direct and specific elements of comparison to the reader, for the right criticism, dispensing interruptive researches. However, even revisiting the traditional theories, for this comparative and critical exposure purpose, they will be kept by the side of our main concerns, as “aliena materia.” Irrespective of the validity of any or all of the elements of this discussion, and their meaning as the philosophical universe of this thesis, the purpose of this work is demonstrating and justifying the existence and meaning of prehistoric moral archetypes arisen directly from the very first social needs and efforts for survival. These archetypes are the definition of the essential foundation of ethics, its aggregation to the collective unconscious and corresponding logic organization and transmission to evolutionary stages of the human genome and different relations space-time, irrespective of any contemporary experience of the individuals. The system defined by these archetypes composes an evolutionary human social model. Is this a metaethical position? Yes, it is. Moreover, as in any metaethical reasoning, we should look carefully for the best and coherent routes, as the Analytical Philosophy offers them. Thus, this work should reasonably demonstrate that morals are not a cultural product of the civilized men or modern societies and that despite being subject to several cultural relative aggregations and subtractions, its essential foundations are archetypal and have never structurally changed. This reasoning induces that morality is an original attribute of the “homo sapiens”; it is not a property and nor an accident: it integrates the human essence and belongs to the realm of the ontological human identity. The human phenomena is a continuing process, playing its role between random determination and free will, and we need to question how morality began and how did it come to us in the present.

What are the relationships between an entity and the space at which it is located? And between a region of space and the events that take place there? What is the metaphysical structure of localization? What its modal status? This paper addresses some of these questions in an attempt to work out at least the main coordinates of the logical structure of localization. Our task is mostly taxonomic. But we also highlight some of the underlying structural features and we single (...) out the interactions between the notion of localization and nearby notions, such as the notions of part and whole, or of necessity and possibility. A theory of localization—we argue—is needed in order to account for the basic relations between objects and space, and runs afoul a pure part-whole theory. We also provide an axiomatization of the relation of localization and examine cases of localization involving entities different from material objects. (shrink)

In this paper I will present three arguments (based on the notions of constitution, metaphysical reality, and truth, respectively) with the aim of shedding some new light on the structure of Fine’s (2005, 2006) ‘McTaggartian’ arguments against the reality of tense. Along the way, I will also (i) draw a novel map of the main realist positions about tense, (ii) unearth a previously unnoticed but potentially interesting form of external relativism (which I will label ‘hyper-presentism’) and (iii) sketch a novel (...) interpretation of Fine’s fragmentalism (which I contrast with Lipman’s 2015, 2016b, forthcoming).

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.

Joining an antagonistic phosphoinositide (PtdInsP) kinase and phosphatase into a single protein complex may regulate rapid and local PtdInsP changes. This may be important for processes such as membrane fission that require a specific PtdInsP and that are innately local and rapid. Such a complex could couple vesicle formation, with erasing of the identity of the donor organelle from the vesicle prior to its fusion with target organelles, thus preventing organelle identity intermixing. Coordinating signals are postulated to switch the relative (...) activities of the kinase and phosphatase in a spatio‐temporal manner that matches membrane fission events. The discovery of two such complexes supports this hypothesis. One regulates the interconversion of phosphatidylinositol and PtdIns(3)P by joining the Vps34 PtdIns 3‐kinase and the myotubularin 3‐phosphatases. The other regulates the interconversion between PtdIns(3)P and PtdIns(3,5)P2 through the Fab1/PIKfyve kinase and the Fig4/mFig4 phosphatase. These lipids are essential components of the endosomal identity code. (shrink)

Grounding contingentism is the doctrine according to which grounds are not guaranteed to necessitate what they ground. In this paper I will argue that the most plausible version of contingentism is incompatible with the idea that the grounding relation is transitive, unless either ‘priority monism’ or ‘contrastivism’ are assumed.

According to Composition is Identity, a whole is literally identical to the plurality of its parts. According to Mereological Nihilism, nothing has proper parts. In this note, it is argued that Composition is Identity can be shown to entail Mereological Nihilism in a much more simple and direct way than the one recently proposed by Claudio Calosi.

What is the relation between parts taken together and the whole that they compose? The recent literature appears to be dominated by two different answers to this question, which are normally thought of as being incompatible. According to the first, parts taken together are identical to the whole that they compose. According to the second, the whole is grounded in its parts. The aim of this paper is to make some theoretical room for the view according to which parts ground (...) the whole they compose while being, at the same time, identical to it. (shrink)
