There are few problems to which legal philosophers have devoted more attention than the relationship between morality and law, or, said in different terms, between the “good” and the “obligatory”. One might think that all that should and could be said about it has already been uttered or written. Nevertheless philosophy — and legal philosophy is no exception — is just this: rethinking old problems which are in fact always new,1 and for which no definitive solution is given — nor (...) is possible, I would add — and which need a permanent effort of reassessment. There is no reason for disappointment or despair in this endless work. It is neither pointless nor irrelevant. (shrink)

Effective methods for evaluating the reliability of statements issued by witnesses and defendants in hearings would be an extremely valuable support to decision-making in court and other legal settings. In recent years, methods relying on stylometric techniques have proven most successful for this task; but few such methods have been tested with language collected in real-life situations of high-stakes deception, and therefore their usefulness outside lab conditions still has to be properly assessed. In this study we report the results obtained (...) by using stylometric techniques to identify deceptive statements in a corpus of hearings collected in Italian courts. The defendants at these hearings were condemned for calumny or false testimony, so the falsity of (some of) their statements is fairly certain. In our experiments we replicated the methods used in previous studies but never before applied to high-stakes data, and tested new methods. We also considered the effect of a number of variables including in particular the homogeneity of the dataset. Our results suggest that accuracy at deception detection clearly above chance level can be obtained with real-life data as well. (shrink)

Many of the problems traditionally related to the interpretation of Leibniz' theory of relations may be seen in a better light considering essentially two factors: 1) the different plans (ontological, metaphysical, psychological and logical-linguistic) implied by Leibniz reflections on the subject; 2) the reference to scholastic and late-scholastic texts read or consulted by Leibniz. Relations for Leibniz are, from a metaphysical point of view, denominations only seemingly external, they are in reality denominationes intrinsecae, and are founded on the general connection (...) of all things. From a psychological point of view they are abstract entities that our mind builds by resemblance. From an ontological point of view they are individual accidents inherent to the substances. From a logical-linguistic point of view they are abstract structures that connect the one to the other at least two subjects. The propositions in which they appear, as for example the proposition “Paris loves Helen” are transformed by Leibniz in equivalent propositions joined by operators, which in medieval logic were known as termini reduplicantes (terms which define mostly intensional contexts). This may be seen with sufficient clarity examining the last part, until now inedited, of the famous passage about Paris and Helen published by Couturat in his Opuscules. (shrink)

La caída del Muro de Berlín fue saludado por muchos analistas y académicos como el inicio de una nueva era. Con el fin de la Guerra Fría se vislumbraba una nueva etapa de paz y prosperidad. Tras la “revolución liberal” algunos avistaban el “fin de la historia”. Pero tal esperanza se disipó rápidamente: la desaparición del “socialismo real” relanzó un capitalismo desenfrenado y no sólo en los países ayer bajo la órbita soviética. El ordoliberalismo entendido como el establecimiento de un (...) modelo económico altamente competitivo y garantizado jurisdiccionalmente, se infiltró también en las instituciones europeas. La crisis del año 2010 vino a confirmar para Europa su deriva neoliberal, tecnocrática. La onda expansiva del 9 de noviembre de 1989 aún no ha concluido. Nuevas turbulencias aguardan. El Brexit también puede interpretarse en esta clave, como una empresa más de demolición, “liquidación”, “liberalización”. (shrink)

: Jerry Fodor and Zenon Pylyshyn have proposed a purely referential-causal semantics, a semantics without meanings. Adopting Pylyshyn’s previous treatment of the fact that we can perceive and track something before we have any idea of what that is, these authors claim that such causal relations to external entities allow us to word-label them and thereby build an entire lexicon with specific referents. I disagree and explain why I do so. The kind of semantics that I prefer is radically opposite: (...) the one proposed by Noam Chomsky and Paul Pietroski. This is an internalist semantics that only has meanings, reference being indirect, often indefinite, sometimes problematic. Chomsky insists that the only posit that is tenable is the internal structure of the speaker-hearer, a complex, abstractly characterizable, computational-derivational apparatus, optimal if left alone, that interfaces with other cognitive apparatuses: the articulatory-perceptual one and the conceptual-intentional one, satisfying the constraints that they impose. I show that the semantics proposed by Fodor and Pylyshyn is especially problematic when inexistent entities, possible entities, fictional characters and objects in the remote past are examined. It is, however, problematic even when dealing with more ordinary concepts. On the contrary, an internalist semantics avoids all these problems. Keywords: Internalist Semantics; Theory of Meaning and Reference; Jerry A. Fodor; Noam Chomsky; Paul Pietroski Menti con significati Riassunto: Jerry Fodor e Zenon Pylyshyn hanno proposto una semantica interamente causale-referenziale, una semantica priva di qualsiasi nozione di significato. Adottando la precedente trattazione di Pylyshyn di come è possibile percepire e inseguire oggetti prima di avere alcuna idea di cosa essi siano, questi autori pretendono che queste interazioni causali con enti esterni bastano a etichettarli con dei termini lessicali, costruendo un intero lessico con referenti specifici, senza la componente del significato. Io dissento e spiego perché. Il tipo di semantica che adotto è diametralmente opposto, una semantica che ha solo significati, per la quale i referenti esterni sono indiretti, spesso non definiti, talvolta problematici. Noam Chomsky e Paul Pietroski hanno perfezionato questa semantica puramente internalista, insistendo che l’unico attributo sostenibile è la struttura mentale interna al locutore, una struttura complessa, caratterizzabile solo a un livello di astrazione adeguato, atta a soddisfare i vincoli imposti dai sistemi cognitivi con i quali interagisce: quello articolatorio-percettivo e quello concettuale-intenzionale. Mostro che la semantica proposta da Fodor e Pylyshyn si scontra con problemi insolubili quando tratta enti inesistenti, enti possibili, invenzioni letterarie e oggetti appartenenti a un passato remoto. In effetti, si scontra con problemi insolubili anche quando tratta oggetti e proprietà ordinari. Una semantica interamente internalista non incontra nessuno di questi problemi. Parole chiave: Semantica internalista; Teoria del significato e del riferimento; Jerry A. Fodor; Noam Chomsky; Paul Pietroski. (shrink)

We prove ExpTime-membership of the satisfiability problem for loosely ∀-guarded first-order formulas with a bounded number of variables and an unbounded number of constants. Guarded fragments with constants are interesting by themselves and because of their connection to hybrid logic.

We establish a simple condition, based on the willingness to bet on events, under which two biseparable preferences have cardinally equivalent utilities.

Pigliucci, Massimo A recent New York Times article has noted a new trend in secular writings, what the author, James Atlas, termed 'Can't-Help-Yourself books'. This trend includes writings by prominent scientists and secularists that are characterised by two fundamental - and equally misguided - ideas: an over-enthusiastic embrace of science, and the dismissal of much of human experience under the generic label of 'illusion'.

Di Massimo di Tiro si conoscono pochi dettagli biografici. Le fonti antiche, concordi nel ritenerlo ‘filosofo’ e ‘filosofo platonico’, affermano che le sue dissertazioni o indagini filosofiche sono da ricondursi al suo primo soggiorno a Roma, al tempo dell’imperatore Commodo. Le quarantuno dissertazioni filosofiche di Massimo di Tiro offrono una visione privilegiata della cultura imperiale del secondo secolo, epoca in cui, dominante l’eleganza stilistica, anche la filosofia non disdegnava di dispiegare i propri contenuti mediante il bello stilo dello (...) strumento retorico. Nello svolgimento dei temi, perlopiù platonici nell’ispirazione e orientati ad argomenti presenti al dibattito coevo, ma comunque non escludenti altre influenze filosofiche, Massimo di Tiro si mostra pensatore dalla non banale semplicità. Muovendosi fra filosofia e letteratura, fra Platone e Omero, egli calibra l’erudizione sul filtro di un’esigenza educativa di ampio respiro. Nel volume si presenta la prima traduzione italiana completa dal greco. Il commento critico, aggiornato al dibattito accademico internazionale, mira a mostrare come l’opera del pensatore meriti una rinnovata attenzione nell’ambito degli studi classici letterari e filosofici, giacché nel delineare il quadro culturale del tempo essa consente di meglio precisare alcuni non marginali aspetti del platonismo del secondo secolo.

Biological research on race has often been seen as motivated by or lending credence to underlying racist attitudes; in part for this reason, recently philosophers and biologists have gone through great pains to essentially deny the existence of biological human races. We argue that human races, in the biological sense of local populations adapted to particular environments, do in fact exist; such races are best understood through the common ecological concept of ecotypes. However, human ecotypic races do not in general (...) correspond with 'folk' racial categories, largely because many similar ecotypes have multiple independent origins. Consequently, while human natural races exist, they have little or nothing in common with 'folk' races. (shrink)

Decision-making assisted by algorithms developed by machine learning is increasingly determining our lives. Unfortunately, full opacity about the process is the norm. Would transparency contribute to restoring accountability for such systems as is often maintained? Several objections to full transparency are examined: the loss of privacy when datasets become public, the perverse effects of disclosure of the very algorithms themselves, the potential loss of companies’ competitive edge, and the limited gains in answerability to be expected since sophisticated algorithms usually are (...) inherently opaque. It is concluded that, at least presently, full transparency for oversight bodies alone is the only feasible option; extending it to the public at large is normally not advisable. Moreover, it is argued that algorithmic decisions preferably should become more understandable; to that effect, the models of machine learning to be employed should either be interpreted ex post or be interpretable by design ex ante.

In this paper a new trajectory-based representation to non-relativistic quantum mechanics is formulated. This is ahieved by generalizing the notion of Lagrangian path which lies at the heart of the deBroglie-Bohm “ pilot-wave” interpretation. In particular, it is shown that each LP can be replaced with a statistical ensemble formed by an infinite family of stochastic curves, referred to as generalized Lagrangian paths. This permits the introduction of a new parametric representation of the Schrödinger equation, denoted as GLP-parametrization, and of (...) the associated quantum hydrodynamic equations. The remarkable aspect of the GLP approach presented here is that it realizes at the same time also a new solution method for the N-body Schrödinger equation. As an application, Gaussian-like particular solutions for the quantum probability density function are considered, which are proved to be dynamically consistent. For them, the Schrödinger equation is reduced to a single Hamilton–Jacobi evolution equation. Particular solutions of this type are explicitly constructed, which include the case of free particles occurring in 1- or N-body quantum systems as well as the dynamics in the presence of suitable potential forces. In all these cases the initial Gaussian PDFs are shown to be free of the spreading behavior usually ascribed to quantum wave-packets, in that they exhibit the characteristic feature of remaining at all times spatially-localized.

It is often contended that certain enhancement technologies are acceptable, because they simply update traditional ways of pursuing the improvement of human capacities. This is not true with reference to moral bioenhancement, because of the radical difference between traditional and biotechnological ways of producing moral progress. These latter risk having serious negative effects on our moral agency, by causing a substantial loss of freedom and capacity of authentic moral behaviour, by affecting our moral identity and by imposing a standard conception (...) of moral personality.

Evolutionary theory is undergoing an intense period of discussion and reevaluation. This, contrary to the misleading claims of creationists and other pseudoscientists, is no harbinger of a crisis but rather the opposite: the field is expanding dramatically in terms of both empirical discoveries and new ideas. In this essay I briefly trace the conceptual history of evolutionary theory from Darwinism to neo-Darwinism, and from the Modern Synthesis to what I refer to as the Extended Synthesis, a more inclusive conceptual framework (...) containing among others evo–devo, an expanded theory of heredity, elements of complexity theory, ideas about evolvability, and a reevaluation of levels of selection. I argue that evolutionary biology has never seen a paradigm shift, in the philosophical sense of the term, except when it moved from natural theology to empirical science in the middle of the 19th century. The Extended Synthesis, accordingly, is an expansion of the Modern Synthesis of the 1930s and 1940s, and one that—like its predecessor—will probably take decades to complete. (shrink)

The term “scientism” is used in a variety of ways with both negative and positive connotations. I suggest that some of these uses are inappropriate, as they aim simply at dismissing without argument an approach that a particular author does not like. However, there are legitimate negative uses of the term, which I explore by way of an analogy with the term “pseudoscience.” I discuss these issues by way of a recent specific example provided by a controversy in the field (...) of bioethics concerning the value, or lack thereof, of homeopathy. I then frame the debate about scientism within the broader context of C.P. Snow’s famous essay on the “two cultures.”. (shrink)

This article is based on a paper given in December 2013 at a German–Italian workshop on Jürgen Habermas’ theory. Massimo Rosati had been studying Jürgen Habermas’ thought and classical sociology in the Durkheimian tradition for years. Because of his own Durkheimian reading of communicative action, he had been unsurprised when Habermas began to write systematically on religion. In this article, he addresses the new post-secular sensitivity to the remnants of mimetic and mythic worldviews within theoretical ones and discusses the (...) sacred as a universal historical structure of human consciousness.
