The duality theory established by Halmos in [2] for boolean hemimorphism applies of course to the diagonalizable algebra, because ντν is an hemimorphism. For commodity in working on diagonalizable algebras we recall the basic facts and give the characteristic conditions on the dual of ντν.

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.

The problem of distance from the truth, and more generally distance between hypotheses, is considered here with respect to the case of quantitative hypotheses concerning the value of a given scientific quantity.Our main goal consists in the explication of the concept of distance D(I, ) between an interval hypothesis I and a point hypothesis . In particular, we attempt to give an axiomatic foundation of this notion on the basis of a small number of adequacy conditions.

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

There are two major possible responses to the question: what (if anything) can justify a basic income experiment? An experiment might be justified either because it gathers positive empirical evidence supporting rolling out a basic income, or because it justifies the moral desirability of such a measure. This paper critically explores both responses, the “empirical” and “ethical claim” in light of the Barcelona B-MINCOME pilot, alongside other similar experiments. We sustained that although the empirical claim is necessary, there seems to (...) be sufficient data to easily predict that all future experiments are to gather positive results too. Consequently, we argue that experiments are particularly well-equipped to foster debates on the work ethics and on the ethical dimension of social policies and welfare regimes in general. (shrink)

This paper makes first steps toward a systematic investigation of how pertinence to topic contributes to determine deductively valid reasoning along with preservation of designated values. I start from the interpretation of Weak Kleene Logic WKL as a reasoning tool that preserves truth and topic pertinence, which is offered by Jc Beall. I keep Beall’s motivations and I argue that WKL cannot meet them in a satisfying way. In light of this, I propose an informal definition of a topic-sensitive logic (...) and I proceed to turn it into a formal one by deploying the topic-algebraic framework from the Topic-Sensitive Intentional Modalities project by Francesco Berto. I apply the framework in order to define semantically a ‘classical topic-sensitive logic’ CTSL that meets Beall’s motivations and proves topic-sensitive. Then, I prove results that connect CTSL and any possible topic-sensitive logic to the tradition of containment logics and provide a unification tool for a wide range of recent proposals in philosophical logic. A topic-theoretical interpretation of WKL is then offered without prejudice to the fact that the logic is not topic-sensitive. Finally, the paper discusses some conceptual issues and research perspectives. (shrink)

The relationships between art and cognition constitute a very wide set of largely unexplored and at times undefined or much too speculative problems. The field is narrowed down by imposing some constraints. It is proposed that the depiction of cast shadows, in its early history, could provide an ideal case study which conforms to the constraints. This paper addresses some methodological problems of the study of this case. A sample of relevant Renaissance images is discussed. A typology of depicted cast (...) shadows is proposed upon which further empirical research could be built. (shrink)

This article examines the normative structure of the concept of health and tries to suggest an account of it in a phenomenological-hermeneutic framework. It is argued that the concept of health has a logical priority to illness, though the latter has an experiential priority. The fundamental feature of the concept of health as discussed in the literature is initially recognized in the notion of ‘norm’, in both the bio-statistical and normative-ideal sense. An analysis of this body of literature reveals some (...) weaknesses in bio-statistical definitions of health as well as in those normative ones which endorse a value-relativity thesis. An approach based on the analogical structure of language is then advanced. In this framework, the notion of biological normativeness proposed by G. Canguilhem is connected with an analysis of the language of health through etymologies. It is argued that health can be characterized as an analogy of ‘plenitude’, which is the common ideal reference of the various health-concepts. The analogical structuring of language allows the recognition of different levels of meaning, and therefore of different kinds of normativeness (biological, mental, social, moral). Some hints of a theory of health deriving from this framework are then given. Keywords: analogy, health, hermeneutics, norm, plenitude CiteULike Connotea Del.icio.us What's this? (shrink)

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

In the literature on mereology it is often accepted that mereological universalism entails extensionalism. More precisely, many accept that, if parthood is assumed to be a partial order, the thesis that every plurality of entities has a mereological fusion entails the thesis that different composite entities have different proper parts. Central to this idea is the principle known as ‘Weak Supplementation’ which many take to impose an important constraint on the relation of proper parthood. In this paper I argue that (...) this claim is false as the principle that I will call ‘Minimal Supplementation’ appears to be capable of doing all the work done by Weak Supplementation but without entailing extensionalism if conjoined with universalism and core mereology.

From a hermeneutical position, the article examines why tension is created between «method» on one hand and circularity on the other. The latter, being unity as well, is the foundation of natural hermeneutics of which it has been said that to be human is to interpret. With this purpose in view, the author has sought to restore to essential Greek terms their archaic meaning which centuries of vernacular usage have rendered blurry, finding that, in accordance with the Greek symbolon, man's (...) conscience of «I am Here and Now» is symbolic unity, viz. a strained unity in search of The Superior Unity that makes him Methodos, Circle, His Own Future, and Metaphysics.

The aim of the paper is to provide a relational explanation of the sources of moral normativity, within a Neo-Kantian framework. To this purpose, the key notions employed are those of we-society and stance-taking, developed by Neo-Kantian philosopher Heinrich Rickert. Specifically, by resorting to such notions, the paper attempts to overcome two limits ascribed to the theory of moral normativity of Ch. Korsgaard: namely W. Smith’s objection of solipsism and S. Crowell’s problem of non-deliberate action, whereby Ch. Korsgaard’s identification of (...) the source of normativity in reflection would lead her theory to a form of solipsism and to failing to explain actions based on so-called ‘mindless coping’. In tackling these objections, the paper outlines a Rickertian inspired theory, according to which the sources of moral normativity can be explained on the basis of the heterological I-You relationship, which is the foundation of the we-society intended as a set of values, patterns of expectations, tacit consents, and procedural knowledge.

This paper compares the conception of substantial change put forth by Peter of Mantua (d. 1399) in his De primo et ultimo instanti with the one developed by Albert of Saxony (ca. 1320–1390). According to Albert, (i) each substantial form, save for the intellective soul, is a spatially-extended entity with actual quantitative parts that are co-located with the parts of matter they inform, and (ii) these quantitative parts are generated and corrupted one after another over an extended interval of time. (...) From (i) and (ii), Albert deduces that (iii) the substantial change of material substances as individuals (save for human beings) is a temporally extended process. This is what I call the ‘piecemeal’ conception of substantial change. I show that Peter of Mantua is significantly indebted to this conception. Indeed, he endorses both (i) and (ii). Moreover, he even extends this approach to the process by which the intellective soul informs matter and is separated from it. Nevertheless, I argue that, thanks to his peculiar doctrine of numerical sameness over time, Peter rejects (iii) and maintains, instead, that the substantial change of any material substance as an individual is an instantaneous event.

: Suppose a scientist discovers a new, unpredicted phenomenon. How can one ascertain the causes, properties and laws of the phenomenon? How can one plan the investigation of the circumstances that affect the phenomenon, and of the effects that the new phenomenon could produce? If the phenomenon is completely unexpected and does not fit any previous theory, it is impossible to provide a theoretical prediction of its likely properties. In the empiricist tradition, therefore, the recommended method was to investigate all (...) possibilities, because in such cases it is impossible to exclude a priori anything. William Stanley Jevons provided a clear criticism of this method. It is impossible to investigate all possibilities, because they are boundless. Is it then impossible to plan the research of unexpected new phenomena? No. Jevons pointed out an alternative. According to Jevons, a scientist confronting a new, unexpected phenomenon, should compare it to other known phenomena to establish analogies. This comparison should allow the researcher to find out one or several known phenomena similar to the new one. This paper will present and discuss Jevons’ proposal in the context of late 19th century methodology of science. Keywords: scientific method; empirical research; analogy; Jevons, William Stanley.

Neste estudo, busca-se uma exposição e uma análise da teoria tomasiana da “restituição” (restitutio). Isso implica apresentar a restitutio como parte da teoria da justiça comutativa e expor os vários aspectos de consideração que servem como pressupostos e condições para a sua realização virtuosa. Em particular, procura-se analisar a confluência de motivos normativos e penitenciais que a abordagem de Tomás de Aquino contém e que, ao final, é decisiva para a devida compreensão da dimensão de obrigação que a restituição importa.

O artigo tenta diferenciar, caracterizar e ordenar diversas figuras da identidade na fenomenologia pós-husserliana. Em primeiro lugar, assinalam-se questões formuladas pela análise da ipseidade em Heidegger. Em segundo lugar, chama-se a atenção para duas tendências divergentes. Por um lado, Lévinas sustenta que uma fissão da identidade é o resultado da responsabilidade pelos outros, e Waldenfels desenvolve uma lógica da responsividade que questiona o autodesenvolvimento e a autopreservação. Por outro lado, Ricoeur sustenta que o ordenamento da vida num relato equivale a (...) uma identidade narrativa, e M. Henry oferece uma elaborada análise da vida interior como um processo de auto-afecção. Por último, tendo como base as distinções delineadas por X. Zubiri, afirma-se que existem fenômenos que oferecem um sustento a um sentido experiencial da identidade, e que isso pode se vincular à noção husserliana do eu como pólo, isto é, ao ponto de partida dos desenvolvimentos fenomenológicos.El artículo intenta diferenciar, caracterizar y ordenar diversas figuras de la identidad en la fenomenología post-husserliana.

First, issues raised by Heidegger's analysis of selfhood are pointed out. Secondly, attention is given to two divergent trends. On the one hand, Levinas contends that a fission of identity is the outcome of responsibility for others, and Waldenfels advances a logic of responsiveness that questions self-development and self-preservation. On the other hand, Ricoeur argues that the ordering of life in a story amounts to a narrative identity, and M. Henry affords an elaborate analysis of inward life as a process of self-affection. Finally, on the basis of distinctions outlined by X. Zubiri, it is contended that there are phenomena that uphold an experiential sense of identity. This can be linked to the Husserlian notion of an ego as a pole of acts, i.e., the starting point of phenomenological developments. (shrink)

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

Language plays a crucial role in human forms of action coordination. This paper examines problems concerning the satisfaction of a major and complex condition of coordination of actions grounded in dialogue, i.e., equality of argumentative competence. It is, indeed, the satisfaction of this condition that defines the autonomy of the subjects participating in and committed to a dialogue situation. From a political point of view, this question can be examined as a problem of dialogical democracy. This paper proposes the autonomy (...) of subjects as a major condition for the realization of such a political form. (shrink)

In Greek mythology, the Chimera is a fire-breathing monster with three heads: one of a lion, one of a horned goat, and one of a powerful dragon. Of similar construction is the presence of three structures in US society, whiteness, patriarchy, and capitalism, which are overwhelmingly represented, valued, and espoused when examining areas of progress, i.e., family income, poverty rates, high school and college graduation rates, and home ownership. This modern American three-headed beast controls, manipulates, and permeates all aspects of (...) US society irrespective of class, culture, or gender. Using critical race theory and critical whiteness studies, this critically interpretive parable draws from the ways in which whiteness, patriarchy, and capitalism function in social, cultural, economic, and educational spheres. The parable tells the story of Sue Libertad and analyzes how this metaphorical Chimera, despite its ubiquity, silently permeates all aspects of her life. Not until a tragic outbreak occurs, does the hegemony of this chimera erodes and Sue. (shrink)

Este ensayo se ocupa de la preservación de tesis formuladas por San Agustin en la fenomenología de Scheler. En primer lugar, se examinan aspectos principales del _ordo amoris _scheleriano. Este orden se revela en actos emocionales y se concibe como la esencia de un orden del mundo, que es también el orden de Dios. Puesto que los pensamientos de Dios son los paradigmas de la creación, se sigue que las cosas son aprehendidas _in lumine Dei _en tanto se las contempla (...) en su verdadero ser. Esto implica que el hombre es el co-ejecutor de la acción divina por medio de una efectuación segunda (_Nachvollzug_). El hombre es un buscador de Dios según un teomorfismo que independiza al espíritu humano finito de todas las realidades vitales y psíquicas. Por tanto, los actos religiosos son caracterizados según la fórmula agustiniana según la cual nuestro corazón permanece inquieto mientras no descansa en Dios. Este impulso no puede ser satisfecho por objetos finitos. Finalmente, se presta atención a la apropiación scheleriana del énfasis de San Agustín en el papel del amor como base de los actos de conocimiento y voluntad. (shrink)

Arts, Ecologies, Transitions provides in depth insights into how aesthetic relations and current artistic practices are fundamentally ecological and intrinsically connected to the world. As art is created in a given historic temporality, it presents specific modalities of productive and sensory relations to the world. With contributions from more than 45 researchers, this book tracks evolutions in the arts that demonstrate an awareness of the environmental, economic, social, and political crises. It proposes interdisciplinary approaches to art that clarify the multiple (...) relationships between art and ecology through an exploration of key concepts such as collapsonauts, degrowth, place, recycling, and walking art. All the artistic fields are addressed from visual arts, theatre, dance, music and sound art, cinema, photography, including those that are rarely represented in research such as digital creation or graphic design, to showcase the diversity of artistic practices in transition. Through original research this book presents ideas in an accessible format. It book will be of interest to students and researchers in the fields of environmental studies, ecology, geography, cultural studies, architecture, performance studies, visual arts, cinema, music and literature studies.

It is given an explicit description of coproducts in the category of Kleene algebras in terms of the dual topological spaces. As an application, a description of dual spaces of free Kleene algebras is given. It is also shown that the coproduct of a family of three-valued ukasiewicz algebras in the category of Kleene algebras is the same as the coproduct in the subcategory of three-valued ukasiewicz algebras.

Nesse particular a resposta não poderia ser mais afirmativa.

Il saggio focalizza quattro significati fondamentali del concetto di seconda natura in Hegel e ne ricostruisce i legami, i nessi interni, le implicazioni per la comprensione dell’intera Geistesphilosophie. Attraverso il concetto di seconda natura, infatti, è possibile evidenziare la connessione tra spirito soggettivo e spirito oggettivo e mostrare che le sfere dello spirito non sono prive di unificazione e provengono da una radice comune. Al termine del saggio emerge che il concetto di seconda natura ha inoltre uno statuto ambivalente: da (...) un lato, esso rende possibile l’idealizzazione della natura e l’innalzamento alla dimensione dello spirito, dall’altro implica una naturalizzazione dello spirito ossia la sua autonegazione.
