The DAMA project is an observatory for rare processes and it is operative deep underground at the Gran Sasso National Laboratory of the I.N.F.N. In particular, the DAMA/LIBRA (Large sodium Iodide Bulk for RAre processes) set-up consists of highly radiopure NaI(Tl) detectors for a total sensitive exposed mass of ≃250 kg. Recent results, obtained by this set-up by exploiting the model independent annual modulation signature of Dark Matter (DM) particles, have confirmed and improved those obtained by the former DAMA/NaI experiment. (...) A model independent evidence for the presence of Dark Matter particles in the galactic halo is cumulatively obtained at 8.2 σ C.L. No systematics or side reactions able to account for the measured modulation amplitude and to contemporaneously satisfy all the many specific requirements of the signature have been found or suggested by anyone over more than a decade. An example of one of the many possible model dependent corollary quests for the candidate particles and for the related astrophysical, nuclear and particle physics scenarios is presented considering the whole cumulative exposure. Future perspectives are shortly addressed. (shrink)

Searches for non-paulian nuclear processes, i.e. processes normally forbidden by the Pauli–Exclusion–Principle (PEP) with highly radiopure NaI(Tl) scintillators allow the test of this fundamental principle with high sensitivity. Status and perspectives are addressed.

L’essai vise à reconstruire dans l’ Estetica come scienza dell’espressione e linguistica generale de Croce de 1902 la relation complexe entre les concepts d’intuition, d’expression et de sensibilité. Pour Croce, l’activité esthétique semble toujours osciller entre une forme de connaissance et une productivité qui trouve dans la matérialité du médium expressif (en particulier l’art) sa propre façon d’apparaître au niveau sensible.

Bernard Berenson used to refer to Giovanni Morelli as «the founder of the Method». With these words, he meant that Morelli was the scholar who, first, transformed connoisseurship in a science, giving to the discipline a stringent method. Does Morelli’s theory of painting really deserve this praise? To answer this question, this paper examines in the first part the philosophical and scientific background of Morelli’s doctrine, showing how its original debt payed to romantic philosophy went replaced by a neat positivist (...) orientation. In the second part, the Method itself is discussed, asking in which measure it was anticipated by the intuitions of art experts such as Giulio Mancini or Luigi Crespi and discussing the nature and epistemological relevance of the so-called “morellian details”, that is the forms of the nails, of the ears, of the hair’s curls in paintings. Are these details really sufficient for the attribution of a painting to an artist? Which role play the documents in connoisseurship? And, more generally, how important is aesthetic value in the morellian “Method”? (shrink)

En este artículo se quiere trazar una teoría política de la insurrección en el pensamiento de Max Stirner, en tanto alternativa ética y política a la revolución. Se mostrará cómo, según el pensador alemán, la revolución es en última instancia una estrategia fallida de emancipación en tanto en cuanto no libera al individuo de las formas de subjetividad que lo mantienen dependiente del poder. Más en general, se enseñará como el orden liberal post-revolucionario, detrás del lenguaje secular de los derechos, (...) las libertades y la igualdad, engendra técnicas más sutiles de gobernabilidad del individuo. La insurrección, en cambio, puede ser vista como un rechazo de las identidades y de los roles que disciplinan al individuo. Al respecto, se prestará una atención especial al concepto stirneriano de Eigenheit, como estrategia ética de auto-determinación y liberación de las formas rígidas de la subjetividad. En última instancia, se querrá mostrar cómo todo el proyecto político de la insurrección stirneriana se basa en un anarquismo ontológico que rechaza la lógica teleocrática del racionalismo moderno y pone en entredicho la misma noción de realización. The aim of this article to outline a political theory of insurrection in Max Stirner’s thought as an ethical and political alternative to revolution. I will show that revolution is ultimately a failed strategy of emancipation as it does not free the individual from the forms of subjectivity that keep her dependent on power. Insurrection, on the other hand, can be seen as a rejection of the identities and roles that discipline the individual. In this regard, special attention will be paid to the Stirnerian concept of Eigenheit as an ethical strategy of self-determination and liberation from rigid forms of subjectivity. Ultimately, I will show how the whole political project of the Stirnerian insurrection is based on an ontological anarchism that rejects the teleocratic logic of modern rationalism and calls into question the very notion of realization.

We analyse the extent of possible computations following Hogarth ([2004]) conducted in Malament–Hogarth (MH) spacetimes, and Etesi and Németi ([2002]) in the special subclass containing rotating Kerr black holes. Hogarth ([1994]) had shown that any arithmetic statement could be resolved in a suitable MH spacetime. Etesi and Németi ([2002]) had shown that some relations on natural numbers that are neither universal nor co-universal, can be decided in Kerr spacetimes, and had asked specifically as to the extent of computational limits there. (...) The purpose of this note is to address this question, and further show that MH spacetimes can compute far beyond the arithmetic: effectively Borel statements (so hyperarithmetic in second-order number theory, or the structure of analysis) can likewise be resolved: Theorem A. If H is any hyperarithmetic predicate on integers, then there is an MH spacetime in which any query ? n H ? can be computed. In one sense this is best possible, as there is an upper bound to computational ability in any spacetime, which is thus a universal constant of that spacetime. Theorem C. Assuming the (modest and standard) requirement that spacetime manifolds be paracompact and Hausdorff, for any spacetime there will be a countable ordinal upper bound, , on the complexity of questions in the Borel hierarchy computable in it.

This paper develops the concept of ‘creative attention’. Against classical theories that understand attention as a spotlight that brings objects into focus, I will argue that attention is a complex phenomenon structured in different layers. The most basic layer is perceptual, passive and pre-predicative: at this level, attention is creative – and this is the central claim of this paper – because it institutes meanings and rules for our behaviour.

We show that the set of ultimately true sentences in Hartry Field's Revenge-immune solution model to the semantic paradoxes is recursively isomorphic to the set of stably true sentences obtained in Hans Herzberger's revision sequence starting from the null hypothesis. We further remark that this shows that a substantial subsystem of second-order number theory is needed to establish the semantic values of sentences in Field's relative consistency proof of his theory over the ground model of the standard natural numbers: -CA0 (...) (second-order number theory with a -comprehension axiom scheme) is insufficient. We briefly consider his claim to have produced a solution to the semantic paradoxes by introducing this conditional. We remark that the notion of a operator can be introduced in other settings. (shrink)

el presente artículo quiere investigar el papel de la mística en la teoría política de Gustav Landauer. La tesis que se defenderá es que la “conservación revolucionaria” que caracteriza la propuesta política landaueriana tiene que enmarcarse en una concepción mística del tiempo histórico, basada en una recuperación del pasado como instrumento de emancipación política. Para esta finalidad se analizará, en un primer párrafo, el contenido utópico a la vez que restaurador de la noción landauerianana de revolución, y, en un segundo (...) apartado, la propuesta acerca de una nueva comunidad socialista. Finalmente, se concluirá que el “romanticismo revolucionario” que entraña la teoría política del autor, y sus continuas referencias a la vida social y política de la Edad Media, puede ser entendido sólo a la luz de un anarquismo mesiánico donde una forma sui generis de espiritualidad y la recuperación del pasado juegan un rol determinante para un auténtico proyecto revolucionario.

We represent truth sets for a variety of the well known semantic theories of truth as those sets consisting of all sentences for which a player has a winning strategy in an infinite two person game. The classifications of the games considered here are simple, those over the natural model of arithmetic being all within the arithmetical class of $\Sum_{3}^{0}$.

"Some patients find it difficult to be in the present because they are stuck in the past; others, by contrast, struggle to remain connected with the past and are suspended in a so-called present that is effectively atemporal, that is out of time”.1 For psychoanalysts, the most profound and ultimately ethical way that we can help individuals, is by helping them know themselves. This involves discovering how they were shaped by their past and how their ongoing self-experience cannot be understood (...) in isolation from its constitutive contexts. Psychoanalysts help patients explore foundational questions such as: ‘Who am I?’ ‘How did I get here?’ ‘How am I implicated in my own suffering?’ ‘How can I grow and flourish and truly engage with my life?’. The answers to these questions emerge from a detailed exploration of the persons lived relational history, their current social and relational context and the political systems within which they are embedded. It is via this expansion of self-awareness that individuals can access agency and true freedom of choice. The clinical approach presented by Notini et al 2 is grounded in a completely different, radically decontextualised understanding of human experience. Their conceptualisation of Phoenix’s gender identity is ahistorical and atemporal: it is indeed ‘out of time’. For these authors, gender identity is assumed to be an immutable core essence, much like Ehrensaft’s3 ‘true gender self….there from birth’. It simply ‘is’. This is a …. (shrink)

One of Heidegger’s most important descriptions of bodily existence can be found in his Nietzsche lectures. This paper aims to elucidate this “metaphysics of the body” both in relation to Heidegger’s Leibniz-interpretation in the later Marburg lectures as well as in the context of his later thought. Leibniz and Nietzsche are Heidegger’s points of departure in the attempt to think the difference between θεωρία and πραξις beyond Being and Time: It is only by understanding their relationship, through a radical re-thinking (...) of the problem of corporeality, no longer as a noun (der Leib) but as a verb (leiben), that one can possibly move beyond every traditional dualism, between theory and praxis but also and most notably between being and becoming.

This article puts forward some observations about the literary form of Documentalità. The genre to which Documentalità belongs is undoubtedly the philosophical treatise. This is a novelty, because the philosophical treatise is not a popular literary form with contemporary philosophers. But it is a genre that proves to be functional in the project of philosophical reconstruction pursued by Ferraris, and that do not necessarily conflict with the Derridean roots from which Documentality moves.

This paper aims to conceptualize the phenomenology of attentional experience as ‘embodied attention.’ Current psychological research, in describing attentional experiences, tends to apply the so-called spotlight metaphor, according to which attention is characterized as the illumination of certain surrounding objects or events. In this framework, attention is not seen as involving our bodily attitudes or modifying the way we experience those objects and events. It is primarily conceived as a purely mental and volitional activity of the cognizing subject. Against this (...) view, the phenomenology of Maurice Merleau-Ponty shows that attention is a creative activity deeply linked with bodily movements. This paper clarifies and systematizes this view and brings it into dialogue with current empirical findings as well as with current theoretical research on embodied cognition. By doing this, I spell out three main claims about embodied attention: the transcendentalism of embodiment for attention, the bodily subjectivity of attention, and the creativity of embodied attention.

We look at various notions of a class of definability operations that generalise inductive operations, and are characterised as “revision operations”. More particularly we: (i) characterise the revision theoretically definable subsets of a countable acceptable structure; (ii) show that the categorical truth set of Belnap and Gupta’s theory of truth over arithmetic using \emph{fully varied revision} sequences yields a complete \Pi13 set of integers; (iii) the set of \emph{stably categorical} sentences using their revision operator ψ is similarly \Pi13 and which (...) is complete in Gödel’s universe of constructible sets L; (iv) give an alternative account of a theory of truth—realistic variance that simplifies full variance, whilst at the same time arriving at Kripkean fixed points.

The general topic of this book is the metaphysics of the subject in Kantian transcendental philosophy. A critical appreciation of Kant's achievements requires that we be able to view Kant's positions as transformations of pre-Kantian philosophy, and that we understand the ways in which contemporary philosophy changes the letter of Kantian thought in order to be true to its spirit in a new philosophical horizon. Descartes is important in two respects. One the one hand, he institutes a philosophical movement which (...) can be said to culminate in Kant; on the other hand, Descartes is one of the major opponents against whom Kant argues in establishing his own position. In either case, the Cartesian cogito is a central concern. Wilfred Sellars restates and transforms Kantian positions in the context of contemporary philosophy after the "linguistic turn", using the Platonic metaphor that thought is similar to discourse.

In diesem Band deckt Diego D'Angelo semiotische Strukturen in der Husserl’schen Phänomenologie der Wahrnehmung auf. Ist es der Phänomenologie darum zu tun, die Erfahrung von Dingen in unserer Umwelt zu beschreiben, so ist dabei der Begriff des Horizontes von zentraler Bedeutung: Was wir unmittelbar wahrnehmen, verweist immer schon auf anderes, was nur „mitgegeben“ ist. Wenn wir Dinge wahrnehmen, haben wir nur eine bestimmte Perspektive, d.h. wir sehen lediglich einen Aspekt. Aber wir nehmen immer ganze Gegenstände wahr (wir sehen Tische (...) und Stühle und andere Menschen). Jeder dieser Gegenstände erscheint in einem Feld weiterer Gegenstände, und es ist der Horizontbegriff, der es erlaubt, das Verhältnis zwischen Selbstgegebenheit und Mitgegebenheit zu explizieren. Dieses Buch stellt den ersten detaillierten Versuch dar, die Ursprünge solcher horizontaler Felder in semiotischen Strukturen zu suchen. Aus der Verbindung zwischen Husserls eigener Semiotik und seiner Phänomenologie der Wahrnehmung ergibt sich, dass das wahrgenommene Phänomen als Zeichen verstanden werden muss. Das Zeichen wiederum bezeichnet etwas, was in leiblicher Bewegung eingeholt werden kann. Mit der Verbindung von Leiblichkeit, Semiotik und Wahrnehmung thematisiert diese Monographie das Verhältnis zwischen folgenden phänomenologischen Forschungsgebieten: • Husserls Semiotik der Wahrnehmung in den Logischen Untersuchungen • Phänomenologische Raumanalyse – kinästhetische Indikation • Horizont und Noema • Passive Anzeige • Zeichen und Leiblichkeit als Grundlagen der Fremderfahrung • Genetische Phänomenologie und Semiotik der Erfahrung • Protentionen und teleologische Semiose • Induktion und Ursprung des menschlichen Ichs Das Buch eröffnet die Möglichkeit, Husserls Phänomenologie jenseits einer Metaphysik der Präsenz zu verstehen. Zudem leisten D'Angelos Einzeluntersuchungen einen Beitrag zu aktuellen Diskussionen in der Philosophie der leiblichen Kognition. – Eine hilfreiche Leseempfehlung für • Interessierte Themenneulinge • Bachelor- und Masterstudenten der Geisteswissenschaften • Hochschulabsolventen sowie Forschungswissenschaftler.
