Some algebraic structures of the set of all effects are investigated and summarized in the notion of a(weak) orthoalgebra. It is shown that these structures can be embedded in a natural way in lattices, via the so-calledMacNeille completion. These structures serve as a model ofparaconsistent quantum logic, orthologic, andorthomodular quantum logic.

Resumo: No presente artigo, busca-se esclarecer os conceitos agostinianos de “vontade” e “livre-arbítrio”, em especial com base no Livro I da obra De libero arbitrio. Procura-se situar a abordagem agostiniana no contexto da história filosófica do conceito de vontade, bem como detalhar aspectos próprios e específicos da primeira fase de escritos de Agostinho sobre a vontade e a liberdade em comparação com períodos posteriores. Defende-se a ideia de que a estrutura da teoria da ação livre de Agostinho é fundamentalmente apresentada (...) em De libero arbitrio I, de acordo com diferenças importantes entre vontade, livre-arbítrio, liberdade da vontade e liberdade de decisão. Defende-se, ademais, que a primeira teoria agostiniana da liberdade de ação pode ser vista como um tipo de libertarismo.Palavras-chave: Agostinho, De libero arbitrio I, vontade, livre-arbítrio, liberdade, teodiceia.

Philosophers of science have developed several accounts of how consideration of scientific models can prompt learning about real-world targets. In recent years, various authors advocated the thesis that consideration of so-called minimal models can prompt learning about such targets. In this paper, I draw on the philosophical literature on scientific modelling and on widely cited illustrations from economics and biology to argue that this thesis fails to withstand scrutiny. More specifically, I criticize leading proponents of such thesis for failing to (...) explicate in virtue of what properties or features minimal models supposedly prompt learning and for substantially overstating the epistemic import of minimal models. I then examine and refute several arguments one may put forward to demonstrate that consideration of minimal models can prompt learning about real-world targets. In doing so, I illustrate the implications of my critique for the wider debate on the epistemology of scientific modelling. (shrink)

A partire dalla produzione saggistica e letteraria di Umberto Eco, l’articolo analizzerà l’immaginario del Medioevo inteso come culla di ogni genere di millenarismo. La trattazione prenderà avvio dal suo saggio Palinsesto su Beato ; tenendo conto dell’originalità della prospettiva strutturalista di Eco, si confronterà l’ultima riedizione di questo scritto con un quadro bibliografico sul ruolo dell’Apocalisse di San Giovanni in seno alla tradizione occidentale. Il primo riferimento sarà la tesi genealogica di Karl Löwith, il quale nel suo Significato e fine (...) della storia affermò che le moderne filosofie della storia rispondono alla stessa ispirazione millenarista della cultura cristiana. Il secondo confronto sarà con uno dei ritratti dell’eresiarca Fra Dolcino; nella fattispecie, sarà considerata la prospettiva del filosofo socialista Antonio Labriola, elaborata a fine Ottocento per distinguere le applicazioni scientifiche del materialismo storico dai suoi fraintendimenti escatologici. Questi due opposti interlocutori condurranno a problematizzare l’interpretazione del millenarismo per come rappresentato da Umberto Eco ne Il nome della rosa. Il romanzo intende infatti l’apocalittica dolciniana come la prefigurazione del terrorismo degli Anni di Piombo? O si tratta di una mera strizzata d’occhio, un gioco con il lettore, il quale è chiamato a non confidare troppo nella potenza simbolica delle analogie? Considering Umberto Eco’s articles and novels, the paper will examine the imaginary of the Middle Age as the cradle of every kind of millenarianism. The analysis will start from Eco’s essay Palinsesto su Beato. Looking at the originality of his structuralist view, I will compare the last editing of this text with a bibliographical framework about the role of the Apocalypse of St. John in the Western tradition. The first reference will be the genealogical thesis of Karl Löwith, who in Meaning in History affirmed that the modern philosophies of history have the same eschatological aim of the Christian culture. The second comparison will be with a portrait of the medieval heresiarch Fra Dolcino. In this case, I will consider the perspective of the socialist philosopher Antonio Labriola, who elaborated it at the end of the XIX Century to distinguish the scientific applications of historical materialism from his eschatological misinterpretations. These two opposite references will drive me to problematize the representation of millenarianism as it was depicted by Umberto Eco in his The Name of the Rose. Indeed, is Dulcinian millenarianism intended by the novel as a prefiguration of the political terrorism in Italy during the Years of Lead? Or is this only a wink, a joking interaction with the reader, who should be careful to rely not on the symbolic strength of analogies? (shrink)

Unger shows how a changed practice of legal analysis can reshape the dominant institutions of representative democracy, market economy and free civil society.

The article deals with the lines along which manifold senses of horizonedness emerge and their reference to potentiality as a starting-point. The first section examines Gurwitsch's analyses of field-potentialities and margin-potentialities in the light of distinctions drawn by Husserl in terms of latency and patency. It is contended that Husserl's concept of latency encompasses both modes of potentiality. The second section shows how the world- horizon functions as a background- horizon and alternation- horizon conceived of as the two fundamental modes (...) of non-thematic consciousness. In this respect, an attempt is made to link this theme with Gurwitsch's description of the acquisition of the character of positional index as a worldly existent. The third section is concerned with how potentiality develops into an all-encompassing domain that can be anticipated as an ideal totality and into a pregiven ground, and outlines an approach to the complementarity of this threefold characterization. This development falls out of Gurwitsch's framework for the analysis of horizonedness. The article concludes with a characterization of the encasement-of-one-in-another of horizons. Reasons are suggested for the application of some ideas of Gurwitsch on thematic transformation to this sequence of levels. (shrink)

Over the last few decades, there have been intense debates concerning the effects of markets on the morality of individuals’ behaviour. On the one hand, several authors argue that markets’ ongoing expansion tends to undermine individuals’ intentions for mutual benefit and virtuous character traits and actions. On the other hand, leading economists and philosophers characterize markets as a domain of intentional cooperation for mutual benefit that promotes many of the character traits and actions that traditional virtue ethics accounts classify as (...) virtuous. In this paper, I join this debate and argue for three claims of general interest to philosophers, economists and policy makers. First, market transactions do not reliably promote individuals’ intentions for mutual benefit, and often select against such intentions. Second, the set of so-called market virtues lacks a substantial overlap with the set of character traits that traditional virtue ethics accounts classify as virtuous. And third, many seemingly virtuous actions observed in market contexts are merely actions in accordance with virtue rather than genuine actions from virtue. These three claims do not license opposition to markets, but challenge the main empirical and theoretical presuppositions of leading virtue ethics defences of markets. (shrink)

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.

En el trabajo, intento repensar la teoría penal de Carlos Nino, desarrollada durante sus estudios doctorales y posdoctorales, a la luz de su teoría de la democracia deliberativa, elaborada desde los años 80. Nino no tuvo la oportunidad de revisar plenamente sus estudios penales en la materia, luego de desarrollar su teoría de la democracia y este artículo se propone entonces dar algunos primeros pasos en esa dirección y explorar algunas posibles implicaciones de dicha tarea. In this work, I try (...) to re-think Carlos Nino’s theory about the Criminal Law, which he developed while he pursued his doctoral and post-doctoral studies, under the light of his deliberative theory of democracy, which he elaborated since the 1980s. Nino had no chance to develop this revision, so this article suggests ways to begin with this required re-elaboration. (shrink)

In the standard approach to quantum mechanics, closed subspaces of a Hilbert space represent propositions. In the operational approach, closed subspaces are replaced by effects that represent a mathematical counterpart for properties which can be measured in a physical system. Effects are a proper generalization of closed subspaces. Effects determine a Brouwer-Zadeh poset which is not a lattice. However, such a poset can be embedded in a complete Brouwer-Zadeh lattice. From an intuitive point of view, one can say that these (...) structures represent a natural logical abstraction from the structure of propositions of a quantum system. The logic that arises in this way is Brouwer-Zadeh logic. This paper shows that such a logic can be characterized by means of an algebraic and a Kripkean semantics. Finally, a strong completeness theorem for BZL is proved. (shrink)

Ce travail expose et discute la réception de Hans Jonas effectuée au sein de la « science de l’image » (Bildwissenschaft). On présente, en premier lieu, le débat actuel sur l’image dans le cadre de cette Bildwissenschaft. En second lieu, on expose les principaux moments de la réception de Jonas dans ledit contexte et on analyse les positions fondamentales de Jonas à propos de l’image et de l’imagination. Enfin, on évalue les avancées et les limites de la réception de Jonas (...) et on prend en considération quelques positions jonassiennes qui peuvent représenter un apport au débat actuel sur l’image.

This chapter focuses on one of the common fallacies in Western philosophy called 'poisoning the well' (PTW). There are some forms of ad hominem varieties that are usually a response to an interlocutor's claims. Unlike them, PTW occurs when we illegitimately prime our audience with a pre‐emptive strike against, or with adverse information about, an argumentative opponent before the latter has had a chance to say anything in her own defense, or in defense of her point of view. This has (...) the insidious effect of creating a conceptual framework according to which the audience – and maybe even the interlocutor herself – will interpret her claims as 'fulfilling' and 'confirming' the presumptions buried inside this conceptual trap. Most of the time Karl Popper's criterion of falsifiability is still quite a useful tool and one that can help us gain a firmer understanding of PTW. (shrink)

We investigate an expansion of quasi-MV algebras ([10]) by a genuine quantum unary operator. The variety of such quasi-MV algebras has a subquasivariety whose members—called cartesian—can be obtained in an appropriate way out of MV algebras. After showing that cartesian . quasi-MV algebras generate ,we prove a standard completeness theorem for w.r.t. an algebra over the complex numbers.

The idea that what we perceive are tropes is anything but new. In fact, it was one of the reasons why the ontology of tropes was postulated in the first place. Still, the claim that we perceive tropes is invariably and purely based on pre-philosophical intuitions or, indirectly, either as a supporting argument for the advantages of content view when compared to the relational view of experience, or as a supporting argument in favor of the irreducible subjective character of experience. (...) In this paper, I take the content view for granted and argue in favor of what is herein referred to as the trope-content view of experience. My defense is a case of inference to the best explanation. The trope-content view can meet all reasonable desiderata on the experience and its content without assuming gaps or making the ad hoc assumption that there are different layers of content, or so shall I argue.

In quantum information and computation, entanglement is a resource. When combining concepts, the application of entanglement outside of micro-physical systems is an useful tool. We suggest new cognitive image-based tests that do not need to be translated. No prior knowledge of terms related to the concepts is required, therefore the choice is more intuitive. We examine the merging of two concepts that establish non-classical statistical correlation and present an entanglement-aware vector encoding algorithm. This research’s added value results in an automated (...) system that teaches artificial intelligence to identify and handle entangled concepts. (shrink)

This article compares the theories of democracy of John Dewey and Claude Lefort, identifying some common themes in their otherwise radically different philosophical outlooks. In so doing, it attempts to analyze the philosophical implications of a ‘democracy first’ approach to politics. It then explains in what sense Dewey’s idea of ‘democracy as a way of life’ and Claude Lefort’s conception of ‘democracy as a form of society’ provide the cornerstone of an original and so far insufficiently explored approach to political (...) philosophy. Such an approach offers an alternative both to the classical-liberal and to the critical-radical projects which still dominate contemporary political philosophy. It then indicates some of the potential advantages of such a ‘wide view’ for contemporary debates in democratic theory. (shrink)

Nesse trabalho, pretendo poder mostrar que é um grave equívoco interpretarmos o papel das representações sensíveis na obra teórica de Kant como conteúdos não-conceituais (na acepção contemporânea técnica do termo “conteúdo” que, tais como dêiticos mentais, representariam o que aparece no espaço e no tempo de forma de re. A interpretação alternativa que me parece adequada é a seguinte: sem possuírem um conteúdo representacional próprio, a representação sensível deve ser entendida fundamentalmente como uma relação cognitiva entre o sujeito e as (...) entidades objetivas no espaço e no tempo com as quais ele está contato epistêmico. Nos termos dessa relação, a referência imediata da intuição sensível ao seu respectivo objeto é entendida como uma forma de conhecimento por contato com tais entidades. Denomino a minha própria interpretação de relacionismo. (shrink)

In this paper I offer a first account of a practice-based conception of normativity for the political domain. This standpoint is used to relocate the most sophisticated normative practices of justification and critique within an experience-based framework, that of the human being as a “normative creature.” I begin by discussing the two major paradigms in political theory, showing that their neglect of this broad framework of normativity is a serious drawback. I then proceed to articulate the central elements of a (...) practicebased account of normativity: the notions of normative practices and normative orders, and an account of the rationality potential of normativity as practice.

This article critically examines two central concepts in normative theory—ethical life and morality—by comparing the pragmatist approach with that of Critical Theory. This is done by way of a close scrutiny of Axel Honneth’s reading of the pragmatist philosophers John Dewey and George H. Mead. This focus on Honneth’s use of pragmatism serves as a port of entry to provide a comparative analysis of pragmatism and Critical Theory’s approaches to normativity. As I intend to show, Honneth’s troubles with making sense (...) of the pragmatist approach to normativity are a litmus test of some persistent ambiguities at the heart of his understanding of normativity. I set the stage by reconstructing Honneth’s reading of Dewey and Mead. That will provide the background against which to set up a comparison between the pragmatist conception of normativity and that of Critical Theory, with a view to assessing their relative validity. I then relate Honneth’s reading of the pragmatists to his own philosophical project and to the important place occupied in it by the same dualism of ethical life and morality. (shrink)

I propose a revision of the received lexicography of μεσότης with regard to Plato’s and Aristotle’s use of the word. In their works, μεσότης never indicates something that merely ‘lies in the middle’, and rather hints at what establishes a reason-grounded, ἀναλογία-like relationship between two extremes. Particularly controversial occurrences of the word μεσότης are connected to the introduction of Aristotle’s ethical and perceptual doctrines of the mean, in Nicomachean Ethics II and De Anima II.12. In this regard, I shall briefly (...) mention some promising directions of inquiry that seem worthy of further investigation. (shrink)

This paper aims to be a compendium on the significance of images as an effective mediator in communication. The research work has resulted from the assumption that it is possible to think of the image as an intrinsically ethical mediator in communication. It has been amply demonstrated that the use of images can reach a level within a communication that is inherently ethical, able to take effective account of an otherness. There cannot exist, in this sense, a communication that is (...) not an appeal, a search for the other, inside this kind of exchange, with full respect of the other’s essence. A communication that makes use of images in an ethical manner will also be more immediate and certainly more effective. In order to address these issues, this paper’s investigation has been deepened with the semiotics bibliography of French essayist Roland Barthes, with particular reference to those essays concerning a kind of poetics of the punctum, an analysis in relation to those images that are able to disrupt the relationship between observer and observed.
