Il volume e un omaggio del P. Selvaggi al pensiero filosofico del Prof. Annibale Pastore, eminente studioso vissuto tra la seconda meta del XIX secolo fino alla prima meta del XX secolo. Il volume parte dalla iniziale riflessione sulla filosofia della scienza, sui suoi metodi e sul suo valore alle considerazioni sulla logica e in particolare sulla logica aristotelica, alle relazioni tra la logica e la matematica fino alla elaborazione della sua teoria: la logica del potenziamento basata sulla relativita. (...) Con la sua teoria il Pastore vuole superare sia l'idealismo kantiano sia il materialismo. Egli parte da un dualismo: soggetto e oggetto, natura e spirito, ma lo supera, non con la negazione degli opposti come fanno i materialisti e gli idealisti, bensi mediante l'identificazione dei termini con la relazione che li unisce. Il lavoro del P. Selvaggi e innanzitutto una descrizione dello sviluppo del pensiero di Pastore e un commento critico alle sue elaborazioni e conseguenze. (shrink)

Spesso ha luogo un confronto tra varie concezioni della filosofia della natura, diverse tra loro per il metodo ed il contenuto, ed e bene che la corrente aristotelicotomista, spesso criticata ma non sostituita, vi sia adeguatamente rappresentata. Il libro e diviso in due parti: la conoscenza del mondo e la natura del mondo. Abbondanti sono i riferimenti e le citazioni in varie lingue di filosofi e scienziati dell'antichita fino ad oggi. Filippo Selvaggi e stato professore di logica e (...) di filosofia della natura e della scienza presso la Pontificia Universita Gregoriana. (shrink)

Il presente volume raccoglie diversi articoli, relazioni e conferenze, fatti in circostanze diverse e in vari luoghi durante il decennio 1953-1962. I saggi qui presentati sono stati quindi gia pubblicati tutti, eccetto pochi. Tuttavia essi vengono qui non solo organicamente riuniti, ma anche in molti punti rimaneggiati, completati e in qualche caso fusi insieme. La grande attualita di argomenti di filosofia della scienza ci hanno spinto a curare la presente raccolta, come modesto contributo ad una delle piu urgenti problematiche della (...) cultura moderna. In essa, infatti, se occorre evitare il pericolo che la scienza nel senso stretto subordini a se ogni altro valore, bisogna pero anche riconoscere ad essa il suo reale valore teoretico e pratico ed evitare quindi che la filosofia si isoli in un piano puramente concettuale ed astratto, avulso dalla vera realta dei nostri tempi.

Is truth itself natural? This is an important question for both those working on truth and those working on naturalism. For theorists of truth, answering the question of whether truth is natural will tell us more about the nature of truth (or lack of it), and the relations between truth and other properties of interest. For those working on naturalism who wish to have truth as part of the natural order, answering this question is of paramount importance. In this chapter, (...) we focus primarily on the kinds of theory of truth that occupy the central positions in current debates about truth, namely correspondence theories, deflationary theories, epistemic theories, and pluralist theories, and aim to discern the extent to which truth is a natural property on each view.

McCormick’s book engages with the theoretical and political positions discussed by the Italian philosopher Niccolò Machiavelli about five centuries ago, and, in particular, the creation of the tribunes of the plebs. In ancient Rome, plebeian power had been institutionalised through the creation of tribunes. According to McCormick, a similar institution would offer a legitimate forum for expression to the people in modern democracies. In fact, following Machiavelli’s suggestions, this would contribute to the implementation of a new form of democracy, more (...) respectful of the people and more eager to defend values such as freedom and independence from the influence of the powerful and the rich. In this review, Filippo Del Lucchese comments on McCormick’s book from a Marxist point of view. One of the strongest points of the book is the discussion of the opposition between democracy and republicanism. Over the last decades, the latter has in fact been absorbed into the sphere of influence of the Cambridge School, and neutralised, or at least defused its most interesting and radical aspects. McCormick’s attempt to repoliticise the Machiavellian discourse is indeed praiseworthy, yet, by mainly focusing on the ‘institutionalisation’ of popular power, McCormick fails to discern the most radical elements of Machiavelli’s thought. From this angle, the review discusses McCormick’s use of the category of ‘class’ and offers a different perspective on the revolutionary dimension. (shrink)

Nell’ambito della filosofia della scienza, il dibattito tra realismo scientifico e antirealismo scientifico ricopre un ruolo di straordinaria importanza. In questo ambito, le posizioni filosofiche elaborate non sono poche. The Instrument of Science di Darrell P. Rowbottom presenta e difende una nuova variante della celebre posizione nota come strumentalismo, di chiaro orientamento antirealista. Questa nuova proposta viene denominata strumentalismo cognitivo (cognitive instrumentalism). Nello specifico, gli obbiettivi dell’autore sono due: definire in modo preciso lo strumentalismo cognitivo, chiarendone le tesi costituenti, e (...) mostrare che questa visione è almeno tanto plausibile quanto lo sono le più accreditate teorie realiste della scienza.

Traumatic experiences and post-traumatic stress are highly prevalent in people with psychosis, increasing symptom burden, decreasing quality of life and moderating treatment response. A range of post-traumatic sequelae have been found to mediate the relationship between trauma and psychotic experiences, including the “traditional” symptoms of post-traumatic stress disorder (PTSD). The International Classification of Diseases-11th Edition recognizes a more complex post-traumatic presentation, complex PTSD (cPTSD), which captures both the characteristic symptoms of PTSD alongside more pervasive post-traumatic sequelae known as ‘disturbances in (...) self-organization’ (DSOs). The prevalence and impact of cPTSD and DSOs in psychosis remains to be explored. In the first study of this kind, 144 participants with psychosis recruited from North West United Kingdom mental health services completed measures assessing trauma, PTSD and cPTSD symptoms and symptoms of psychosis. Forty-percent of the sample met criteria for cPTSD, compared to 10% who met diagnostic criteria for PTSD. PTSD and DSOs mediated the relationship between trauma and positive symptoms, controlling for dataset membership. Both PTSD and DSOs mediated the relationship between trauma and affective symptoms but did not explain a significant proportion of variance in negative symptoms. Cognitive and excitative symptoms of psychosis did not correlate with trauma, PTSD or DSO scores. These findings indicate the possible value of adjunct therapies to manage cPTSD symptoms in people with psychosis, pending replication in larger epidemiological samples and longitudinal studies.

Can someone who suspends judgement about a certain proposition <p> be in a relational state of disagreement with someone who believes <p> as well as with some- one who disbelieves <p>? This paper argues for an af- firmative answer. It develops an account of the notions of suspended judgement and disagreement that explains how and why the suspender is in a relational state of disagreement with both the believer and the disbeliever about the very same proposition <p>. More specifically, the (...) paper first provides a characterisation of the norma- tive profile associated with the state of suspended judge- ment in terms of the set of normative commitments that it engenders in the context of inquiry. It then provides a characterisation of the notion of disagreement in terms the incompatibility between the sets of normative com- mitments characteristic of the three states in question— belief, disbelief, and suspension.

Presuppositions and Appropriateness of Assertions In this paper I aim to compare and evaluate two theoretic approaches to pragmatic presuppositions: the Common Ground account and Propositional Context account. According to the Common Ground account proposed by Stalnaker, it is appropriate to assert a sentence p that requires a presupposition q only if q is mutually believed as accepted as true and taken for granted by the interlocutors. Otherwise, Gauker claims that the ground of propositions taken for granted coincides with what (...) he calls the objective propositional context, that is the set of objectively relevant propositional elements that speakers ought to share in order to evaluate the appropriateness of utterances so as to reach the goal of a conversation.The main purpose of my paper is to show that, according to the Propositional Context account, a theory of presupposition has to take into account a normative-objective notion of context. Secondly, I aim to develop a criticism of Gauker's point of view claiming that the Propositional Context account does not account for the number of ways in which a proposition can be taken for granted by the speakers depending on the context. Finally, I propose to integrate Gauker's account with a further condition for appropriateness of assertion which states that: in order to appropriately assert a sentence p that requires a presupposition q, speakers ought to recognize how they should justify q in a specific communicative context.

Mind the Gap Presupposition has been a widely discussed topic in the philosophical and linguistic tradition since the beginning: Frege, in Über Sinn und Bedeutung , claims that the use of a singular term presupposes the existence of the individual denoted. The Fregean example was that to give a truth value to the sentenceKepler died in miserywe need to take for granted the truth of the propositionKepler existedTherefore, is a semantic presupposition of . Since the Fregean stance, analytic scholars have (...) given the following definition: a sentence p semantically presupposes a sentence q if we need the truth of q in order to treat p as endowed with sense, that is, as either true or false. If the presupposition is lacking, then the sentence p lacks a truth value . Russell, in On Denoting , launched a strong criticism of the Fregean theory of semantic presupposition, contrasting the Fregean view with .. (shrink)

Implanting deep brain stimulation (DBS) electrodes in patients with Parkinson’s disease often results in the appearance of a non-infectious, delayed-onset edema that disappears over time. However, the time window between the DBS electrode and DBS stimulating device implant is often used to record local field potentials (LFPs) which are used both to better understand basal ganglia pathophysiology and to improve DBS therapy. In this work, we investigated whether the presence of post-surgery edema correlates with the quality of LFP recordings in (...) eight patients with advanced Parkinson’s disease implanted with subthalamic DBS electrodes. The magnetic resonance scans of the brain after 8.5 ± 1.5 days from the implantation surgery were segmented and the peri-electrode edema volume was calculated for both brain hemispheres. We found a correlation (ρ = −0.81, p < 0.0218, Spearman’s correlation coefficient) between left side local field potentials of the low beta band (11–20 Hz) and the edema volume of the same side. No other significant differences between the hemispheres were found. Despite the limited sample size, our results suggest that the effect on LFPs may be related to the edema localization, thus indicating a mechanism involving brain networks instead of a simple change in the electrode-tissue interface.

According to some critics, Aristotle’s elenctic defence (elenchos, elenchus) of the Law of Non-Contradiction (Metaphysics IV) would be ineffective because it viciously begs the question. After briefly recalling the elenctic refutation of the denier of the Law of Non-Contradiction, I will first focus on Filippo Costantini’s objection to the elenchus, which, in turn, is based on the dialetheic account of negation developed by Graham Priest. Then, I will argue that there is at least one reading of the elenchus that (...) might not be viciously question-begging. In doing so, I will leverage, reinterpret and adjust the distinction between two senses of epistemic dependence, offered by Noah Lemos and originally based on some thoughts about George Edward Moore’s ‘proof of an external world.’ The key point of my counter-objection to recover the elenchus is to use the distinction between a necessary-condition relation between propositions (p only if q) and a grounding relation between facts (the fact that an epistemic agent S believes that p is grounded in the fact that S believes that q), where p and q are the content of S’s beliefs.

Rule A: if it's metaphysically necessary that p, we may validly infer that no one is even partly morally responsible for the fact that p. Our principal aim in this article is to highlight the importance of this rule and to respond to two recent challenges to it. We argue that rule A is more important to contemporary theories of moral responsibility than has previously been recognized. We then consider two recent challenges to the rule and argue that neither challenge (...) successfully undermines the rule's initial appeal. (shrink)

The Catholic University ofAmerica Washington, D.C. WILLIAM A. WALLACE, O.P. Love Your Enemies: Discipleship, Pacifism and Just War Theory. By LISA SOWLE CAHILL. Minneapolis, Minn.: Fortress Press, 1994. Pp. xii + 252. $17.00 (paper). Lisa Cahill's Love Your Enemies: Discipleship, Pacifism and Just War Theory provides an excellent introduction to questions of peace-making and war-making in the history of Western Christianity. Cahill canvasses the standard sources for her history: the generally pacifist period of the New Testament and the early church (chapters two and three); the emergence of the just war tradition with Augustine and Aquinas (chapters four and five); just war, crusade, and pacifist responses during the Reformation period (chapters six through eight); and just war and pacifist responses in the twentieth -century American debate (chapters nine and ten). Love Your Enemies is relatively comprehensive, even-handed, and well-written. Beyond its general competence, Love Your Enemies provides rich theological fare, situating questions on war and peace in the context of Christian discipleship as a whole. One result of using discipleship as the organizing motif is that pacifism gets an unusually sympathetic and fair hearing. Cahill serves as an excellent reporter on these contentious questions. While often intimating her sympathies, she consistently avoids taking decisive positions or closing avenues of exploration. The title of her final chapter -the "Fragility of the Gospel"-reflects this approach. In this chapter Cahill emphasizes that Christian communities must continuously challenge themselves and their society to live out the gospel of peace (239-44). BOOK REVIEWS 323 What does it mean to live as a follower of Jesus today (ix)? This is Cahill's central question. To this end she asks two further questions. First, what is the way of discipleship established by Jesus with regard to doing violence? Second, to what extent can Christians hope to apply this ethic of discipleship to the wider civil society (40)? These questions arise in a variety of forms throughout the book. For instance, Cahill elegantly shows how a Christian's eschatological commitments (i.e., beliefs about the extent to which God's peaceful rule can be established by a community of believers and/or the extent to which this can be realized in "the world") can affect her response to the possibility of doing violence. While setting as one's task the attempt to find a way to combine Christian discipleship with public responsibility has many strengths, it is not without possible pitfalls. Typically, "Christian responsibility" is contrasted with "the evangelical imperative of non-violence" (see 55-56). But this notion of "responsibility" often begs the central question-i.e., for the Christian, can the most "responsible" stance be anything but what Cahill proclaims to be the evangelical stance of non-violence? While Cahill does acknowledge the strength of the argument by advocates of "responsibility" (i.e., those ~ho set up the non-violent stance in opposition to the faithful following of Jesus), she does not explicitly endorse their move. From her self-professed Catholic context, Cahill strives fo harmonize a neo-Thomist understanding of natural law-that there is "an objective moral order, knowable by reason, that yields universal moral laws by which all human persons and communities should abide" (3)-with a more particularistic...

We exhibit several counterexamples showing that the famous Serrin's symmetry result for semilinear elliptic overdetermined problems may not hold for partially overdetermined problems, that is when both Dirichlet and Neumann boundary conditions are prescribed only on part of the boundary. Our counterexamples enlighten subsequent positive symmetry results obtained by the first two authors for such partially overdetermined systems and justify their assumptions as well.

1. Naturalism Naturalism, it has been said, is the distinctive development in philosophy over the last thirty years. There has been a naturalistic turn away from the a priori methods of traditional philosophy to a conception of philosophy as continuous with natural science. The doctrine has been extensively discussed and has won considerable following in the USA. This is, on the whole, not true of Britain and continental Europe, where the pragmatist tradition never took root, and the temptations of scientism (...) in philosophy were less alluring. Contemporary American naturalism originates in the writings of Quine, the metaphysician of twentieth-century science. With extraordinary panache, he painted a largescale picture of human nature, of language and of the web of belief. I believe that in almost every major respect, it is, like the picture painted by Descartes, the great metaphysician of seventeenth-century science, mistaken. But it evidently appeals to the spirit of the times. So it is worthy of critical examination and careful refutation. I shall argue that the naturalistic turn is a cul-de-sac – a turn that is to be passed by if we are to keep to the highroad of good sense. Naturalism, like so many of Quine’s doctrines, was propounded in response to Carnap. As Quine understood matters, Carnap had been persuaded by Russell’s Our Knowledge of the External World that it is the task of philosophy to demonstrate that our knowledge of the external world is a logical construction out of, and hence can be reduced to, elementary experiences. Quine rejected the reductionism of Carnap’s Logischer Aufbau, and found the idealist basis uncongenial to his own dogmatic realist behaviourism, inspired by Watson and later reinforced by Skinner. The rejection of reductionism and ‘unregenerate realism’, Quine averred, were the sources of his naturalism (FME 72). What exactly was this? We can distinguish in Quine between three different but inter-related programmes for future philosophy: epistemological, ontological and philosophical naturalism. Naturalized epistemology is to displace traditional epistemology, transforming the investigation into ‘an enterprise within natural science’ (NNK 68) – a psychological enterprise of investigating how the ‘input’ of radiation, etc., impinging on the nerve endings of human beings can ‘ultimately’ result in an ‘output’ of our theoretical descriptions of the external world..

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.

Two different conceptions of language dominate philosophical reflection on the nature of human language and of human linguistic powers. The first is the conception of language as a calculus of meaning, and of understanding as computational interpretation. This conception is rooted in the exigencies of function-theoretic logic. The notions pivotal to this conception are truth, truth-condition, sense and force, naming and describing (representation), and theory of meaning for natural languages. The alternative conception is an anthropological one, which conceives of language (...) above all as a form of human communicative behaviour, constituted by human practices and manifest in human action. The notions pivotal to this conception are practice, language-game, use and rule of use as given by explanations of meaning, understanding and criteria of understanding. The fundamental principles that inform each of these conceptions are explained. The radical flaws of calculus conceptions of language are laid bare. (shrink)

As the United States is currently prosecuting two wars, it is important to consider whether those wars, and the resulting noncombatantcasualties, can be morally justified. Such consideration can be initiated by considering some of Alan Donagan’s work in his book The Theory of Morality. In that book Donagan sets out to develop, as a philosophical system, that part of the common morality according to the Hebrew-Christian tradition, which does not depend on any theistic beliefs. According to that tradition it is (...) sometimes morally permissible to resort to war. This poses a problem because also part of the tradition is a near absolute prohibition on harming innocent people. Since innocent people die in war, there is a tension here.Donagan claims that this problem can be solved by assigning the blame for some such deaths to the aggressor, thereby permitting (some) resorts to war. This paper shows that this solution is inadequate; and defends a more plausible (and more traditional) justification for some innocent deaths. This justification is consistent with the system Donagan develops, and thus may have application in the consideration of the justification of the two wars currently being prosecuted by the United States.
