La 4e de couverture indique : "Questo lavoro di Giovanni Scirocco è una delle prime ricerche storiche sull'opera di Norberto Bobbio che si avvale in modo siste- matico delle carte del suo archivio personale conservate presso il Centro Studi Piero Gobetti di Torino. Argomento dello studio è il giudizio sulla guerra giusta nelle varie fasi dell'itinerario politico e culturale del filosofo a partire dal 1961, quando Bobbio in colloquio con Günther Anders matura la convinzione che di fronte alla (...) guerra nucleare siamo tutti potenzialmente obiettori di coscienza, fino alle posizioni da lui assunte di fronte alla Guerra del Golfo nel 1991 e alla guerra "umanitaria" con la Serbia nel 1999. In poche agili ma dense pagine il lettore può seguire lo svolgersi nel tempo delle argomentazioni di Bobbio, illustrate con documenti d'archivio e corroborate da una scelta intelligente e felice di brani tratti dai principali saggi bobbiani sulla pace e la guerra: la prefazione al libro "Essere e non essere. Diario di Hiroshima e Nagasaki" di Anders, "Il conflitto termonucleare e le tradizionali giustificazioni della guerra", "Filosofia della guerra nell'era atomica", "Diritto e guerra", "Il problema della guerra e le vie della pace".".

Many philosophers have been attracted to the idea of using the logical form of a true sentence as a guide to the metaphysical grounds of the fact stated by that sentence. This paper looks at a particular instance of that idea: the widely accepted principle that disjunctions are grounded in their true disjuncts. I will argue that an unrestricted version of this principle has several problematic consequences and that it’s not obvious how the principle might be restricted in order to (...) avoid them. My suggestion is that, instead of trying to restrict the principle, we should distinguish between metaphysical and conceptual grounds and take the principle to apply exclusively to the latter. This suggestion, if correct, carries over to other prominent attempts at using logical form as a guide to ground. (shrink)

This paper defends the view that one's own mental states are metaphysically privileged vis-à-vis the mental states of others, even if only subjectively so. This is an instance of a more general view called Subjectivism, according to which reality is only subjectively the way it is. After characterizing Subjectivism in analogy to two relatively familiar views in the metaphysics of modality and time, I compare the Subjectivist View of the Mental with Egocentric Presentism, a version of Subjectivism recently advocated by (...) Caspar Hare. I argue that the Subjectivist View of the Mental goes a considerable way towards solving certain long-standing philosophical puzzles having to do with the unity of consciousness, the contents of self-awareness and the intransmissibility of experiential knowledge through testimony.

Relativists make room for the possibility of “faultless disagreement” by positing the existence of subjective propositions, i.e. propositions true from some points of view and not others. We discuss whether the adoption of this position with respect to a certain domain of discourse is compatible with a realist attitude towards the matters arising in that domain. At first glance, the combination of relativism and realism leads to an unattractive metaphysical picture on which reality comprises incoherent facts. We will sketch the (...) contours of a realist-relativist position called “subjectivism”, which avoids this result by giving up the assumption that the points of view of different subjects are all metaphysically “on a par”.

This paper argues that what is currently the most popular version of temporal Fragmentalism—‘unstructured’ temporal Fragmentalism, as I shall call it—faces a problem of Tensed Belief Explosion. Four possible solutions to this problem are reviewed and shown to be wanting; two more promising ones risk fostering scepticism about the existence of tensed facts—hence, about Fragmentalism itself. The tentative moral is that unstructured versions of Fragmentalism are at best unmotivated and at worst seriously flawed.

There are two intuitions about time. The first is that there's something special about the present that objectively differentiates it from the past and the future. Call this intuition Specialness. The second is that the time at which we happen to live is just one among many other times, all of which are ‘on a par’ when it comes to their forming part of reality. Call this other intuition Egalitarianism. Tradition has it that the so-called ‘A-theories of time’ fare well (...) at addressing the first intuition, but rather badly when it comes to the second. The goal of this article is to offer advice to A-theorists about how to reconcile their view with Egalitarianism. (shrink)

Solving the meta-problem of consciousness requires, among other things, explaining why we are so reluctant to endorse various forms of illusionism about the phenomenal. I will try to tackle this task in two steps. The first consists in clarifying how the concept of consciousness precludes the possibility of any distinction between 'appearance' and 'reality'. The second consists in spelling out our reasons for recognizing the existence of something that satisfies that concept.

In this paper I propose to read and understand gestures as logical tools within a synthetic paradigm of knowledge. This interpretation of gesture is drawn from a new pragmatist reading of reasoning in general, and synthetic reasoning in particular. Complete gestures are actions with a beginning and an end that bear a meaning. It is our regular way to embody vague ideas into singular actions with general meaning. The tool is forged by a dense blending of icons, indices, and symbols (...) and by a complexity of phenomenological characteristics as feelings, actual actions, general concepts and habits. The paper illustrates this new way to look at gestures and different kinds of complete and incomplete gestures. (shrink)

It has been observed that, unlike other kinds of singular judgments, mental self-ascriptions are immune to error through misidentification: they may go wrong, but not as a result of mistaking someone else’s mental states for one’s own. Although recent years have witnessed increasing interest in this phenomenon, three basic questions about it remain without a satisfactory answer: what is exactly an error through misidentification? What does immunity to such errors consist in? And what does it take to explain the fact (...) that mental self-ascriptions exhibit this sort of immunity? The aim of this paper is to bring these questions into focus, propose some tentative answers and use them to show that one prominent attempt to explain the immunity to error through misidentification of mental self-ascriptions is unsuccessful.

Kilimanjaro is an example of what some philosophers would call a ‘vague object’: it is only roughly 5895 m tall, its weight is not precise and its boundaries are fuzzy because some particles are neither determinately part of it nor determinately not part of it. It has been suggested that this vagueness arises as a result of semantic indecision: it is because we didn’t make up our mind what the expression “Kilimanjaro” applies to that we can truthfully say such things (...) as “It is indeterminate whether this particle is part of Kilimanjaro”. After reviewing some of the limitations of this approach, I will propose an alternative account, based on a new semantic relation—multiple reference—capable of holding in a one-many pattern between a term and several objects in the domain. I will explain how multiple reference works, what differentiates it from plural reference and how it might be used to accommodate at least some aspects of our ordinary discourse about vague objects.

Williamson’s anti-luminosity argument has been thought to be in tension with the doctrine that we enjoy privileged epistemic access to our own mental states. In this paper, I will argue that the tension is only apparent. Friends of privileged access who accept the conclusion of the argument need not give up the claim that our beliefs about our own mental states are mostly or invariably right, nor the view that mental states are epistemically available to us in a way that (...) renders everything within our mind ‘open to view’ – arguably, two main pillars of their doctrine. What they need to reject is the idea that the mental is a realm whose ’determinacy’ or ’fineness of grain’ never escapes our appreciation. This idea – I will suggest – is not essential to privileged access and defenders of the doctrine should not be afraid to give it up. (shrink)

According to Leibniz’s infinite-analysis account of contingency, any derivative truth is contingent if and only if it does not admit of a finite proof. Following a tradition that goes back at least as far as Bertrand Russell, several interpreters have been tempted to explain this biconditional in terms of two other principles: first, that a derivative truth is contingent if and only if it contains infinitely complex concepts and, second, that a derivative truth contains infinitely complex concepts if and only (...) if it does not admit of a finite proof. A consequence of this interpretation is that Leibniz’s infinite-analysis account of contingency falls prey to Robert Adams’s Problem of Lucky Proof. I will argue that this interpretation is mistaken and that, once it is properly understood how the idea of an infinite proof fits into Leibniz’s circle of modal notions, the problem of lucky proof simply disappears.

This paper presents a distinctively metaphysical version of the problem of other minds. The main source of this version of the problem lies in the principle that, when it comes to consciousness, no distinction can sensibly be drawn between appearance and reality. I will argue that, unless we want to call that principle into question, we should seriously consider the possibility of accepting the conclusion that other minds are not like our own. This option is less problematic than it might (...) seem at first if we are willing to reconceive facts of consciousness as subjective rather than objective in nature. -/- . (shrink)

According to Russellian monism (RM), the quiddities which underlie the fundamental causal structure of the physical world are also responsible for the existence of phenomenal consciousness. This view has been argued to provide an attractive alternative to physicalism and dualism, but it is plagued by the so-called ‘combination problem’ – namely, the problem of explaining how the quiddities underlying the microphysical structure of a macroscopic conscious agent (e.g., a human being) combine together to constitute his or her phenomenal experiences. In (...) this paper, I will explore a type of monism that avoids the combination problem altogether. According to this view – which I shall call panquidditist monism – all causal roles, and not just the fundamental ones, stand in need of quiddities realizing them. Moreover, the quiddities that realize causal roles at one physical level should not in general be seen as grounded in, or otherwise derivative on, the quiddities that realize causal roles at lower levels. Crucial to the tenability of this view is a distinction between two varieties of grounding – one aiming to metaphysically explain the causal properties of various objects ‘from below’ (vertical grounding), the other aiming to metaphysically explaining them ‘from the inside’ (horizontal grounding). I will argue that, thanks to the distinction between vertical and horizontal grounds, panquidditist monism is well-placed to secure the advantages that RM promises – but, because of the combination problem, fails to deliver – vis-à-vis physicalism and dualism.

Thomas Reid (1710–1796) presented a two-dimensional geometry of the visual field in his Inquiry into the human mind (1764), whose axioms are different from those of Euclidean plane geometry. Reid’s ‘geometry of visibles’ is the same as the geometry of the surface of the sphere, described without reference to points and lines outside the surface itself. Interpreters of Reid seem to be divided in evaluating the significance of his geometry of visibles in the history of the discovery of non-Euclidean geometries. (...) The question will be reexamined with particular attention given to his unpublished manuscripts. These include comments on Saccheri’s work and Reid’s repeated attempts to derive Euclid’s parallel postulate from the axioms of incidence. (shrink)

Thomas Reid presented a two-dimensional geometry of the visual field in his Inquiry into the Human Mind (1764). The axioms of this geometry are different from those of Euclidean plane geometry. The ‘geometry of visibles’ is the same as the geometry of the surface of the sphere, described without reference to points and lines outside the surface itself. In a recent article, James Van Cleve has argued that Reid can secure a non-Euclidean geometry of visibles only at the cost of (...) abandoning his direct realist theory of perception, and reintroducing sense-data. The question will be reexamined by considering two aspects of Reid’s theory of vision: the claim that we do not directly perceive distance by sight and Reid’s characterization of visible figure as a partial notion of an external object. (shrink)

This article explains how Derrida’s notion of an originary or generalised metaphoricity can be understood in terms of the analyses presented in Voice and Phenomenon (1967) in response to Eugen Fink’s question of a ‘transcendental logos’ and of the paradoxical ontological status of phenomenological language. Tracing Fink’s impact on Derrida, as well as the key differences between them, the article shows that underlying Derrida’s reappropriation of the phenomenological concept of ‘life’ is an expansion of indicative relations—which in Husserl typify the (...) function of signs within intersubjective communication and modes of judgement characterised by the non-presence of the intended object—to a general feature of the ‘living present’. While for Fink the indicative or metaphorical nature of the transcendental concept of ‘life’ does not threaten the founding unity it serves to name, for Derrida it is this very unity which is undermined by the proliferation of indication at the core of temporal experience.

According to Reid, color sensations are not extended nor are they arranged in figured patterns. Reid further claimed that ‘there is no sensation appropriated to visible figure.’ Reid justified these controversial claims by appeal to Cheselden's report of the experiences of a young man affected by severe cataracts, and by appeal to cases of perception of visible figure without color. While holding fast to the principle that sensations are not extended, Dugald Stewart tried to show that ‘a variety of colour (...) sensations is a necessary means for the perception of visible figure.’ According to John Fearn, two motives appear to be central to Reid's views about color sensations and extension: his commitment to the Cartesian doctrine of the immateriality of the soul, and his attempt to evade ‘Hume's dilemma’ about the existence and immateriality of the soul. (shrink)

In order to illustrate the difference between sensation and perception, Reid imagines a blind man that by ‘some strange distemper’ has lost all his notions of external objects, but has retained the power of sensation and reasoning. Reid argues that since sensations do not resemble external objects, the blind man could not possibly infer from them any notion of primary qualities. Condillac proposed a similar thought experiment in the Treatise on Sensations. I argue that Condillac can reach a conclusion opposite (...) to that of Reid only by assuming that some particular collections of sensations do indeed resemble the qualities of external objects. Reid had considered a similar case in a manuscript, but he again notices that such complex collections sensations do not resemble the qualities of external objects. (shrink)

According to Reid, opinions that contradict the principles of common sense are not only false but also absurd. Nature has given us an emotion that reveals the absurdity of an opinion: the emotion of ridicule. An appeal to ridicule in philosophical arguments may easily be discounted as a logical fallacy in the same manner as an appeal to the common consent of people. This essay traces the origins of Reid's defense of ridicule in the works of Addison, Hutcheson, Shaftesbury and (...) Campbell. Reid rejected a non-epistemic view of the sense of ridicule. According to Reid, ridicule includes both a feeling and a particular act of judgment based on the principles of common sense. (shrink)

While Hume had a favorable opinion of the new commercial society, Reid envisioned a utopian system that would eliminate private property and substitute the profit incentive with a system of state-conferred honors. Reid’s predilection for a centralized command economy cannot be explained by his alleged discovery of market failures, and has to be considered in the context of his moral psychology. Hume tried to explain how the desire for gain that motivates the merchant leads to industry and frugality. These, in (...) their turn, benefit all society. Reid still saw the desire for money as a degenerate form of the desire for power. The contrast between Hume and Reid, however, has not to be taken too far. On some particular matters of economic policy, such as paper credit, Hume and Reid eventually came to similar views. (shrink)

This article offers a reconstruction of Derrida’s critique of Leibniz. It suggests that in attempting to fit Leibniz into his conception of the history of metaphysics and the all-embracing notion of logocentrism that underwrites it, Derrida presupposes two regimes of logocentrism: one subjective, the other theological. Subsumed into this second mode, Derrida casts Leibniz as a progenitor of structuralism and the new sciences and technologies of information in order to expose their logocentric foundations. However, in doing so, he ends up (...) sidelining the aspect of Leibniz’s ideas that anticipates the specificity of the new epoch of writing he claims to historicise. The article goes on to argue that to grasp this specificity one must look beyond the “expressivist” schema of exterior representation, which Derrida draws from Husserl’s theory of meaning, and instead look to Leibniz’s own formal-combinatorial concept of expression, which exceeds Derrida’s critical framework.

To be successful, the research agenda for a novel control view of cognition should foresee more detailed, computationally specified process models of cognitive operations including higher cognition. These models should cover all domains of cognition, including those cognitive abilities that can be characterized as online interactive loops and detached forms of cognition that depend on internally generated neuronal processing.

In a recent article on Reid’s theory of single and double vision, James Van Cleve considers an argument against direct realism presented by Hume. Hume argues for the mind-dependent nature of the objects of our perception from the phenomenon of double vision. Reid does not address this particular argument, but Van Cleve considers possible answers Reid might have given to Hume. He finds fault with all these answers. Against Van Cleve, I argue that both appearances in double vision could be (...) considered visible figures of the object, and show how this solution might preserve Reid’s direct realism. However, this solution is not compatible with the single appearance of an object predicted by Reid’s theory of single and double vision. This consequence will appear evident once we consider the critique of Reid’s theory of single and double vision formulated by William Charles Wells (1757-1817). Wells argues that Reid’s theory is either incomplete or incompatible with other claims made by Reid. It is incomplete since it fails to specify the unique direction in which we the object in single vision; if it not incomplete and is compatible with the law of monocular direction given by Reid, then it is incompatible with Reid’s claim that we do not perceive immediately distance by sight.

Focusing on his last courses at the Collège de France, the present paper aims at exploring the strategic role the notion of parrhesia plays in the elaboration of Foucault’s critical project, according to which parrhesia is what enables the pas- sage from the concept of problematization as an archaeo-genealogical target of inquiry to the idea of problematization as a verbal act of investigation. To this end, the article argues that parrhesia is the condition of possibility for the problematization of one’s (...) mode of subjectivation, whereby it comes to describe a transformative practice of resistance against the existing power regimes in charge of truth. After tracing the seminal formulation of such a form of resistance in the Socratic imperative of taking care of oneself, the paper then concludes by briefly pointing to the importance of Socrates’ parrhesiastic philosophy for the development of Foucault’s own critical ethos.

This article explores the links between the philosophies of Georges Canguilhem and Gilbert Simondon. It highlights their shared emphasis on the difficult character of human life, framing this difficulty in terms of an existential encounter with problems and their resolutions. It shows how the notion of ‘problem’ which grounds both of their thinking presupposes a neo-vitalist conception of life as purposive behaviour, extended to forms of collective, technical and symbolic activity. The consequences of this conception for Canguilhem's and Simondon's engagement (...) with questions of pedagogy, and the role of philosophical education in particular, are then examined. The article concludes by considering the ambiguous place of anxiety in their work and its significance for thinking about the conditions of knowledge and action. Following Canguilhem and Simondon, I argue for the importance of helping the human organism develop relatively autonomous interior and exterior milieus to cope with life's fundamental difficulty.

Gli antichi Greci la chiamavano métis. Parola comune e anche nome mitologico di divinità. Se consultiamo il vocabolario, ne troviamo due significati: "saggezza" ispirata a "prudenza" e "disegno", nel senso di "piano" concepito da qualcuno. La flessibilità ha a che fare soprattutto con il secondo significato, perché è razionalità strategica e agonistica, in cui la duttilità è insieme ragion d'essere, modo di operare e scopo. Giovanni Bottiroli sostiene da tempo la necessità di elaborare una filosofia di tipo modale, che (...) apra le categorie della logica classica alla coppia rigido/flessibile. In questo saggio porta a compimento una teoria estremamente articolata degli stili di pensiero, la sola che giudica in grado di comprendere l'eterogeneità della mente, il pluralismo logico e semantico, l'identità come polisemia. Se definiamo "rigido" ogni soggetto il cui modo d'essere è la coincidenza con se stesso, la flessibilità non può ridursi infatti a una rigidità indebolita: è inclusiva e avvolgente e le spetta il primato sul piano logico, etico ed estetico. Perché è la flessibilità a renderci liberi. (shrink)

To qualify as a fully rational agent, one must be able rationally to revise one’s beliefs in the light of new evidence. This requires, not only that one revise one’s beliefs in the right way, but also that one do so as a result of appreciating the evidence on the basis of which one is changing one’s mind. However, the very nature of belief seems to pose an obstacle to the possibility of satisfying this requirement – for, insofar as one (...) believes that p, any evidence that not-p will strike one as misleading and, on the face of it, believing that a certain piece of evidence is misleading is incompatible with appreciating the fact that such evidence should bear on the question at hand. Call this the ‘Paradox of Belief Revision’. This paper introduces the Paradox of Belief Revision, compares it with Kripke’s Dogmatism Paradox, and suggests that we may be able to see a way out of the former if we assume that rational agents are systematically aware of their own beliefs as beliefs they have.

FILOSOFIA DA PRÁXIS E AS PRÁTICAS POLÍTICO-PEDAGÓGICAS POPULARES RESUMO: O artigo resgata o sentido “revolucionário” da filosofia da práxis inaugurada por K. Marx e aprofundada por A. Gramsci e aponta conexões com as atuais práticas político-pedagógicas populares. Mostra como Marx revoluciona a concepção de filosofia não apenas porque unifica inseparavelmente pensamento e atividade material, teoria e prática, mas, principalmente pelo fato inaudito de reconhecer o protagonismo histórico do proletariado. É Gramsci, no entanto, quem explicita, amplia e atualiza de maneira original (...) as virtualidades da filosofia da práxis mostrando os aspectos que a projetam como a mais avançada visão de mundo e como expressão revolucionária das classes subalternas que se organizam politicamente para romper com a submissão e se tornar dirigentes. Sendo uma construção histórica que assume diferentes configurações em diversas situações e lugares, o artigo traça uma análise das novas formas que hoje a filosofia da práxis apresenta nas insurgências populares que vêm ocorrendo no Brasil e no mundo.

The debate on the ontological status of spacetime in General Relativity has historically seen two principal philosophical contenders: substantivalism, roughly the view that holds that spacetime exists apart from the material contents of the universe, and relationism, the doctrine that spacetime does not exist, i.e., it is a mere abstract web of spatiotemporal relations among bodies. This dispute, however, has rarely been fought on a cosmological battlefield. In this paper an attempt in this direction is made. The question at issue (...) is the following: is there any feature of our universe that requires or is best explained in terms of a substantival space? I claim that there is indeed: the expansion of the universe, perhaps the most important phenomenon in cosmology, can play such a role. (shrink)

The paper argues for viewing legal validityas a doxastic obligation, i.e. as the obligation toaccept a rule in legal reasoning. This notion of legalvalidity is shown to be both sufficient for thelaywers' needs and neutral in regard to varioustheories of the grounds of validity, i.e. theoriesintended to identify what rules are legally valid, byproposing different grounds for attributing validity.All of these theories, rather then being alternativedefinitions of validity, presuppose the notion hereprovided.This notion is purely normative, but it allows for theconstruction (...) of theories of the grounds of validitywhich give due importance to social expectations andinstitutions. As an example of how this may happen,one such theory is also provided. This theory, whichis presented through a detailed example of a judicialdebate, is based upon the recognition of the(instrumental) value of co-ordination, as thenecessary way to achieve the most valuable purposes ofthe law.
