This monograph uses deconstruction—a philosophical movement originated by Jacques Derrida—to read the most authoritative book in Judaism: the Talmud. Examining deconstruction in comparison with Kant’s and Hegel’s philosophies, the volume argues that the movement opens an innovative debate on Jewish Law. -/- First, the monograph interprets deconstruction within the major streams of continental philosophy; then, it criticizes many aspects of Foucault’s and Agamben’s philosophy, rejecting their notion of law. On these premises, the research delivers a close examination of many fundamental (...) aspects of the Talmud. Consequently, it provides a short history of Rabbinic literature, a history of the dissemination of the Talmud from Babylon to Northern France, and an analysis of Talmudic vocabulary from a deconstructive perspective. Each key concept of the Talmud is analysed according to the deconstructive dialectics between orality and writing. Closing with a comparison between the Talmud and Derrida’s most enigmatic text, Glas, the study argues that deconstruction dismantles the traditional notion of the Talmud to outline a new approach to Jewish Law. -/- Reading the Talmud through deconstruction, this new angle makes the volume an essential resource for students and scholars interested in Jewish studies, continental philosophy, and the Middle East.

L'antigiudaismo cristiano è essenzialmente la credenza che il popolo ebraico debba rinunciare alla propria fede e convertirsi al cristianesimo. In questo testo viene studiata la prima forma sistematica di antigiudaismo sviluppata in termini filosofici e teologici da Agostino d'Ippona. Alla luce dell'analisi filosofica sembra che l'avversione di Agostino per la fede ebraica si fondi su un'autentica rimozione della specificità del popolo eletto, della Legge e della Rivelazione sul Sinai.

The paper engages with a variety of data around a supposedly single biomedical event, that of heart transplantation. In conventional discourse, organ transplantation constitutes an unproblematised form of spare part surgery in which failing biological components are replaced by more efficient and enduring ones, but once that simple picture is complicated by employing a radically interdisciplinary approach, any biomedical certainty is profoundly disrupted. Our aim, as a cross-sectorial partnership, has been to explore the complexities of heart transplantation by explicitly entangling (...) research from the arts, biosciences and humanities without privileging any one discourse. It has been no easy enterprise yet it has been highly productive of new insights. We draw on our own ongoing funded research with both heart donor families and recipients to explore our different perceptions of what constitutes data and to demonstrate how the dynamic entangling of multiple data produces a constitutive assemblage of elements in which no one can claim priority. Our claim is that the use of such research assemblages and the collaborations that we bring to our project breaks through disciplinary silos to enable a fuller comprehension of the significance and experience of heart transplantation in both theory and practice.

The year 2005 has been named the World Year of Physics in recognition of the 100th anniversary of Albert Einstein's "Miracle Year," in which he published four landmark papers which had deep and great influence on the last and the current century: quantum theory, general relativity, and statistical mechanics. Despite the enormous importance that Einstein’s discoveries played in these theories, most physicists adopt a version of quantum theory which is incompatible with the idea that motivated Einstein in the first place. (...) This seems to suggest that Einstein was fundamentally incapable of appreciating the `quantum revolution,’ and that his vision of physics as an attempt to reach a complete and comprehensive description of reality was ultimately impossible to obtain. Relativity theory has provided us with a picture of reality in which the world can be though as independent on who observes it, and the same can be said for statistical mechanics. Instead, quantum mechanics seems to suggest that physical objects do not exist `out there’ when someone is not observing them. In this framework, it is often suggested that any kind of causal explanation is impossible in the atomic and subatomic world, and therefore should be abandoned. This is why many think that it is in principle impossible for quantum theory to provide us with a coherent and comprehensive view of the world, in contrast with what happens with relativity and statistical mechanics. Is it really impossible to pursue Einstein’s ideal of physics also in the quantum framework? This book argues that this is not the case: the central idea is that Einstein’s vision of physics is still a live option, and indeed it is the one that best allows obtaining a unitary understanding of our physical theories. One can consider all the three theories mentioned above, suitably modified, as theories that are able to account and explain the world around us without too much departure from the classical framework. ---------------------------------------------------------------------------------------------------- -------------------------------------------------- -/- La teoria della relatività, la meccanica statistica e la meccanica quantistica hanno profondamente rivoluzionato il nostro modo di concepire spazio, tempo, materia, probabilità e causalità, nonché il rapporto tra universo fisico ed osservatore, nozioni che sono state al centro della discussione filosofica dal mondo greco fino ai nostri giorni. Questo volume, opera di Valia Allori, Mauro Dorato, Federico Laudisa e Nino Zanghì, non solo intende suggerire nuovi metodi di confronto tra fisica e filosofia, ma prova altresì a rendere espliciti i presupposti filosofici che sono presenti nell'interpretazione che i fisici stessi danno del formalismo matematico.

H.-I. Marrou's Traité de la musique selon l'esprit de Saint Augustin is a useful document about the relationship between 1930s French music and non-conformist culture. His stress on the moral aim of music recalls the claim for a spiritual revolution that informs the spirit of 1930 and Jeune France's manifesto: the reading of Marrou's Traité helps us defining the humanistic poetics of music of the '30s, and the historical context mutually explains and justify most of Marrou's thought .His thought is (...) in fact developed in the wake of Christian Platonism revised by Augustine, subject to a series of small changes in sight of a better and more relevant moral theology. The philosophical outcome isn't very convincing, both for many appeals to the authority principle, and for frequent contradictions clearly emerging in his arguments. The tension between the fidelity to the doctrine, the attempts to re-read the music from an apologetic viewpoint and the aim to suggest a practical philosophy produces a methodological setback so striking that it represents one of the greater limits of the Treaty.Marrou's remarks about the relationship between Christianity and ancient philosophy are certainly as interesting as questionable from the point of view of the history of philosophy. He goes so far to correct Augustine himself, especially as regards the Pythagorean influence on his thought, to stress instead a religious component of the music that doesn't seem so evident in the Augustinian analysis.Quest'ultimo viene infatti sviluppato sulla scia del platonismo cristiano mediato da Agostino, che viene sottoposto a una serie di piccoli mutamenti in funzione di una migliore e più attuale teologia morale. L'esito filosofico non è tuttavia dei più convincenti, vuoi per i numerosi appelli al principio d'autorità, vuoi per le frequenti contraddizioni argomentative che emergono dal testo in modo evidente. La tensione tra la fedeltà alla dottrina, il tentativo di rilettura della musica in chiave apologetica e la proposta di una filosofia pratica producono così un vistoso scacco metodologico che rappresenta uno dei limiti maggiori del Trattato.Le considerazioni di Marrou sul rapporto tra cristianesimo e filosofia antica sono certamente molto interessanti ma assai discutibili da un punto di vista storico-filosofico. L’autore si spinge fino a correggere Agostino stesso, soprattutto per quanto riguarda la componente pitagorica della sua riflessione, per sottolineare invece una componente religiosa della musica che non sembra così evidente nella riflessione agostiniana..

The Cogito and the Mexican Salamander.Philosophy and the Rest of Sciences in the late Merleau-Ponty The article examines Merleau-Ponty’s almost parallel reading – in his last courses at the Collège de France – of the Cartesian cogito and the development of the Axolotl, the salamander studied by American biologist Coghill. My hypothesis is that the metaphysics of the cogito and the biology of the Axolotl represented for Merleau-Ponty two ways of access to the same discovery. Descartes came up against a (...) phenomenon, the cogito, which required the reshaping of metaphysics as a sort of (impossible) psychology of the event or the absolute. Within the field of anatomy, Coghill came up against a phenomenon, the embryogenesis of the Axolotl, which similarly required a sort of conversion of anatomy into embryology. Therefore, bios and psyché, “embryonality” and the cogito, would be nothing but the denomination of the objects that psychology and biology meet along their borders, names for what we could refer to as “event,” “continuum,” “becoming” or, according to an old but still suitable definition, “absolute.” This has countless consequences on the relationship between the so-called human sciences and the so-called natural sciences, their eternally missed dialogue, their false complementarity and the illusion that the famous “two cultures” do actually exist.Il Cogito e la lucertola messicana.La filosofia e il resto delle scienze nell’ultimo Merleau-Ponty L’articolo prende in esame la lettura quasi parallela che Merleau-Ponty svolge, negli ultimi corsi di lezione al Collège de France, del cogito cartesiano e dello sviluppo dell’Axolotl, la lucertola studiata dal biologo americano Coghill.

Tutta la metafisica sarebbe psicologia, cioè indicazione del luogo assoluto nel quale è inscritto ogni luogo. Dall’interno dell’anatomia, Coghill siimbatte in un fenomeno, lo sviluppo dell’embrione dell’Axolotl, che esige analogamente che tutta l’anatomia si risolva in embriologia.

I start with the analysis of the possible sources of Islamic authors, such as the Plato’s myth of the cave and its allegorical interpretation given by the philosopher al-Fārābī.I develop some thoughts about the Avicenna’s possible objectives in writing the visionaries tales: 1. the philosophical allegories about the nature of knowledge, 2. the religious allegories with Gnostic character on the theme of the liberation of the soul from its earthly prison, represented by the West, and its consequent salvation, or 3. a combination of these two possible interpretations?The article focuses on Avicenna and the philosophical sources that could have inspired his tales, and taking into account Suhrawardī’s later writing, that has a similar content, but probably with different intentions.

Although the idea of dignity has always been applied to human beings and although its role is far from being uncontroversial, some recent works in animal ethics have tried to apply the idea of dignity to animals. The aim of this paper is to discuss critically whether these attempts are convincing and sensible. In order to assess these proposals, I put forward two formal conditions that any conception of dignity must meet and outline three main approaches which might justify the (...) application of dignity to animals: the species-based approach, moral individualism and the relational approach. Discussing in particular works by Martha Nussbaum and Michael Meyer I argue that no approach can convincingly justify the extension of dignity to animals because all fail to meet the formal conditions and do not provide an appropriate basis for animal dignity. I conclude by arguing that the recognition of the moral importance of animals and their defense should appeal to other normative concepts which are more appropriate than dignity. (shrink)

The main considerations for well planning and hydraulic fracturing in unconventional resources plays include the amount of total organic carbon and how much hydrocarbon can be extracted. Brittleness is the direct measurement of a formation about the ability to create avenues for hydrocarbons when applying hydraulic fracturing. Brittleness can be directly estimated from laboratory stress-strain measurements, rock-elastic properties, and mineral content analysis using petrophysical analysis on well logs. However, the estimated brittleness using these methods only provides “cylinder” estimates near the (...) borehole. We proposed a workflow to estimate brittleness of resource plays in 3D by integrating the petrophysics and seismic data analysis. The workflow began by brittleness evaluation using mineral well logs at the borehole location. Then, we used a proximal support vector machine algorithm to construct a classification pattern between rock-elastic properties and brittleness for the selected benchmark well. The pattern was validated using well-log data that were not used for constructing the classification. Next, we prestack inverted the fidelity preserved seismic gathers to generate a suite of rock-elastic properties volumes. Finally, we obtained a satisfactory brittleness index of target formations by applying the trained classification pattern to the inverted rock-elastic-property volumes. (shrink)

Daniel Dennett is arguably one of the most influential yet radical philosophers in America today. In this volume, Dennett is confronted by colleagues and critics, from philosophy, biology and psychology. His reply constitutes an extensive essay which clarifies, and develops further, central themes in his philosophy. The debate ranges over Dennett's whole corpus, but special attention is given to his major work on consciousness, Consciousness Explained. The volume includes a critical assessement of Dennett's views on behaviouralism and the subjectivity of (...) consciousness, the nature of perception and mental representation, intentional laws and computational psychology, the rationality of thought, culture as a virus, the architecture of mind, and the role of artifacts in thinking. Also included is an introduction to Dennett's philosophy and a full bibliography of his publications. (shrink)

We prove that both of these logics are complete for the product of rational numbers ${\Bbb Q}\times {\Bbb Q}$ (...) with the appropriate topologies. (shrink)

This paper addresses the problem of pluralism in democratic societies, by exploiting some insights from the debate about the epistemology of disagreement. First, by focusing on the permissibility of experiments on nonhuman animals for research purposes, we provide an epistemic analysis of deep normative disagreements. We understand that to mean disagreements in which epistemic peers disagree about both the substantive content of an ethical issue and the correct justificatory reasons for their contrary claims. Second, we argue for a compromise solution (...) in which the reasons for reaching it are not prudential but grounded on the recognition of epistemic peerhood. (shrink)

This paper focuses on the problem of event-triggered control for a class of uncertain nonlinear strict-feedback systems with zero dynamics via backstepping technique. In the design procedure, the adaptive controller and the triggering event are designed at the same time to remove the assumption of the input-to-state stability with respect to the measurement errors. Besides, we propose an assumption to deal with the problem of zero dynamics. Three different event-triggered control strategies are designed, which guarantees that all the closed-loop signals (...) are globally bounded. The effectiveness of the proposed methods is illustrated and compared using simulation examples. (shrink)

Prestack seismic inversion techniques provide valuable information of rock properties, lithology, and fluid content for reservoir characterization. The confidence of inverted results increases with increasing incident angle of seismic gathers. The most accurate result of simultaneous prestack inversion of P-wave seismic data is P-impedance. S-impedance estimation becomes reliable with incident angles approaching 30°, whereas density evaluation becomes reliable with incident angles approaching 45°. As the offset increases, we often encounter “hockey sticks” and severe stretch at large offsets. Hockey sticks and (...) stretch not only lower the seismic resolution but also hinder long offset prestack seismic inversion analysis. The inverted results are also affected by the random noises present in the prestack gathers. We developed a three-step workflow to perform data conditioning prior to simultaneous prestack inversion. First, we mitigated the hockey sticks by using an automatic nonhyperbolic velocity analysis. Then, we minimized the stretch at the far offset by using an antistretch workflow. Last, we improved the signal-to-noise ratio by applying prestack structure-oriented filtering. We evaluated our workflow by applying it to a prestack seismic volume acquired over the Fort Worth Basin, Texas, USA. The results inverted from the conditioned prestack gathers have higher resolution and better correlation coefficients with well logs when compared to those inverted from conventional time-migrated gathers.

This paper defends the case against (sparse) disjunctive properties by means of four Armstrongian arguments. The first of these is a logical atomist argument from truthmaking, which is, broadly speaking, ‘Armstrongian’ (Armstrong 1997). This argument is strong – although it stands or falls with the relevant notion of truthmaking, as it were. However, three arguments, which are prima facie independent of truthmaking, can be found explicitly early in Armstrong’s middle period. Two of these early arguments face a serious objection put (...) forward forcefully by Louise Antony (2003) and Alan Penczek (1997), respectively. I consider these objections and argue that they fail. Thus, even if the argument from truthmaking is indecisive, disjunctive properties should be rejected. (shrink)

A technoeconomic optimization problem for a domestic grid-connected PV-battery hybrid energy system is investigated. It incorporates the appliance time scheduling with appliance-specific power dispatch. The optimization is aimed at minimizing energy cost, maximizing renewable energy penetration, and increasing user satisfaction over a finite horizon. Nonlinear objective functions and constraints, as well as discrete and continuous decision variables, are involved. To solve the proposed mixed-integer nonlinear programming problem at a large scale, a competitive swarm optimizer-based numerical solver is designed and employed. (...) The effectiveness of the proposed approach is verified by simulation results. (shrink)

Prestack seismic analysis provides information on rock properties, lithology, fluid content, and the orientation and intensity of anisotropy. However, such analysis demands high-quality seismic data. Unfortunately, noise is always present in seismic data even after careful processing. Noise in the prestack gathers may not only contaminate the seismic image, thereby lowering the quality of seismic interpretation, but it may also bias the seismic prestack inversion for rock properties, such as acoustic- and shear-impedance estimation. Common postmigration data conditioning includes running window (...) median and Radon filters that are applied to the flattened common reflection point gathers. We have combined filters across the offset and azimuth with edge-preserving filters along the structure to construct a true “5D” filter that preserves amplitude, thereby preconditioning the data for subsequent quantitative analysis. We have evaluated our workflow by applying it to a prestack seismic volume acquired over the Fort Worth Basin, TX. The inverted results from the noise-suppressed prestack gathers are more laterally continuous and have higher correlation with well logs when compared with those inverted from conventional time-migrated gathers.

The focus of this paper is the prima facie plausible view, expressed by the principle of Counter-Closure, that knowledge-yielding competent deductive inference must issue from known premises. I construct a case that arguably falsifies this principle and consider five available lines of response that might help retain Counter-Closure. I argue that three are problematic. Of the two remaining lines of response, the first relies on non-universal intuitions and forces one to view the case I construct as exhibiting a justified, true (...) belief to which none of the usual diagnoses of knowledge failure in Gettier cases apply. The second line involves claiming that Fake Barns and its ilk are misdiagnosed by epistemological orthodoxy as Gettier cases. We are thus confronted by a trilemma: either the case I discuss undermines the first-blush plausible principle of Counter-Closure; or the case I discuss instantiates a novel kind of Gettier case; or a popular conception of a key range of alleged Gettier cases must be rejected. No matter which horn we choose, the case points to a philosophically curious conclusion. (shrink)

Desire has not been at the center of recent preoccupations in the philosophy of mind. Consequently, the literature settled into several dogmas. The first part of this introduction presents these dogmas and invites readers to scrutinize them. The main dogma is that desires are motivational states. This approach contrasts with the other dominant conception: desires are positive evaluations. But there are at least four other dogmas: the world should conform to our desires (world-to-mind direction of fit), desires involve a positive (...) evaluation (the “guise of the good”), we cannot desire what we think is actual (the “death of desire” principle), and, in neuroscience, the idea that the reward system is the key to understanding desire. The second part of the introduction summarizes the contributions to this volume. The hope is to contribute to the emergence of a fruitful debate on this neglected, albeit crucial, aspect of the mind.

This paper investigates the observability of first-order, second-order, and high-order leader-based multiagent systems with fixed topology, respectively. Some new algebraic and graphical characterizations of the observability for the first-order MASs are established based on agreement protocols. Moreover, under the same leader-following framework with the predefined topology and leader assignment, the observability conditions for systems of double-integrator and high-integrator agents are also obtained. Finally, the effectiveness of the theoretical results is verified by numerical examples and simulations.

Jeff McMahan has recently provided a forceful defense of methodological anti-speciesism against speciesists’ claim that species standard is a meaningful criterion to assess the value of lives and the nature of deprivation. In this paper I discuss McMahan’s favored account (the Intrinsic Potential Account) to assess the value of life and the nature of deprivation and challenge its overall ethical and methodological tenability. I level three charges against the Intrinsic Potential Account. I argue, first, that it cannot be consistent with (...) some widely held egalitarian moral intuitions. Second, it is unconvincing in its justification of the idea of equal respect for persons. Third, it is unclear how it can make sense of the value of individual capacities without referring to some species-based standard. Although I remain neutral with respect to the debate between anti-speciesists and speciesists, I argue that anti-speciesists cannot rely on McMahan’s arguments. (shrink)

According to the principle of Knowledge Counter-Closure , knowledge-yielding single-premise deduction requires a known premise: if S believes q solely on the basis of deduction from p, and S knows q, then S must know p. Although prima facie plausible, widely accepted, and supported by seemingly compelling motivations, KCC has recently been challenged by cases where S arguably knows q solely on the basis of deduction from p, yet p is false or p is true but not known . I (...) explore a view that resolves this tension by abandoning KCC in the light of these challenges, and which acknowledges their force but also their limits. Adopting this view helps identify the epistemic constraints that operate on the premises of knowledge-yielding deduction, clarifies the epistemic role of deduction, and allows us to distil the kernel of truth in the motivations that are standardly taken to support KCC.

What I call Mellor’s Question is the problem of whether determinables are properties of their determinates or properties of the particulars that possess these determinates. One can distinguish two basic competing theories of determinables that address the issue, implicitly if not explicitly. On the second-order theory, determinables are second-order properties of determinate properties; on the second-level theory, determinables are first-order properties of the particulars with these determinate properties. Higher-order properties are prima facie ontologically uneconomical, and in line with my general (...) view that ontological parsimony is vital to metaphysics, I consider it highly important which of the two theories is true. Firstly, I argue that the second-level theory offers the best explanation of the explananda (though the race is close), including the important but neglected phenomenon of ‘intermediate determinables’. Secondly, by paying attention to intermediate determinables and instantiation of higher-order properties, I argue that the second-level theory also is more ontologically economical. For these two reasons, this theory is preferable. (shrink)

The principle of equal consideration of interests is a very popular principle in animal ethics. Peter Singer employs it to ground equal treatment and solve the problem of the basis of equality, namely the problem of why we should grant equal treatment despite the variability of people’s features. In this paper, I challenge Singer’s argument because ECOI does not provide plausible grounds to presume that the interests of diverse individuals are actually equal. Analyzing the case of pain and the interest (...) in not suffering in particular, I contend that there are some insurmountable epistemic and axiological problems in accounting for the equality of interests. Besides criticizing ECOI as a basis of equality, I argue that we need to rely on an equality of moral status. I conclude by providing some considerations on the relation between equality and the principle of proportionality. (shrink)

Observables have a dual nature in both classical and quantum kinematics: they are at the same time quantities, allowing to separate states by means of their numerical values, and generators of transformations, establishing relations between different states. In this work, we show how this twofold role of observables constitutes a key feature in the conceptual analysis of classical and quantum kinematics, shedding a new light on the distinguishing feature of the quantum at the kinematical level. We first take a look (...) at the algebraic description of both classical and quantum observables in terms of Jordan–Lie algebras and show how the two algebraic structures are the precise mathematical manifestation of the twofold role of observables. Then, we turn to the geometric reformulation of quantum kinematics in terms of Kähler manifolds. A key achievement of this reformulation is to show that the twofold role of observables is the constitutive ingredient defining what an observable is. Moreover, it points to the fact that, from the restricted point of view of the transformational role of observables, classical and quantum kinematics behave in exactly the same way. Finally, we present Landsman’s general framework of Poisson spaces with transition probability, which highlights with unmatched clarity that the crucial difference between the two kinematics lies in the way the two roles of observables are related to each other.

Biosemiotics argues that “sign” and “meaning” are two essential concepts for the explanation of life. Peircean biosemiotics, founded by Tomas Sebeok from Peirce’s semiotics and Jacob von Uexkül’s studies on animal communication, today makes up the mainstream of this discipline. Marcello Barbieri has developed an alternative account of meaning in biology based on the concept of code. Barbieri rejects Peircean biosemiotics on the grounds that this discipline opens the door to nonscientific approaches to biology through its use of the concept (...) of “interpretation.” In this article, it is noted that Barbieri does not adequately distinguish among Peirce’s semiotics, Peircean biosemiotics, and “interpretation-based” biosemiotics. Two key arguments of Barbieri are criticized: his limited view of science and his rejection of “interpretation-based” biosemiotics. My argument is based on tools taken from a different approach: Robert Rosen’s relational biology. Instead of “signs” and “meanings,” the study begins in this case from the “components” and “functions” of the organism. Rosen pursues a new definition of a law of nature, introduces the anticipatory nature of organisms, and defines the living being as a system closed to efficient cause. It is shown that Code Biosemiotics and Peircean biosemiotics can share a common field of study. Additionally, some proposals are suggested to carry out a reading of Rosen’s biology as a biosemiotic theory. (shrink)
