Dreh- und Angelpunkt des vorliegenden Buches ist der Gemeinschaftsbegriff. Er soll in seinen zahlreichen, komplexen und miteinander verflochtenen Bedeutungsfacetten erortert werden. Im Zuge einer kritischen Text- und Begriffsanalyse wird gezeigt, dass der gemeinsame Gegenstand der Gemeinschaft ein vielschichtiges Phanomen ist, dem in der Denkgeschichte sowie in der Alltagssprache und -kultur zahlreiche Ausdifferenzierungen entsprechen. Die Paradigmen der Gemeinschaft werden in 15 Kapiteln anhand der semantischen Auffacherung der prapositionalen Komposita des Grundwortes -teilung herausgearbeitet. Der Inhalt: Teilung. Heideggers Kreide, oder: Was bedeutet eigentlich, (...) eine Pizza zu teilen? * Aufteilung und Verteilung. "Gemeinsame Guter" und WG-Gesucht * Erteilung. Was ist eine Gabe? * Arbeitsteilung. Offentlichkeit und oikos bei "Hans im Gluck" * Einteilung und Unterteilung. Gemeinschaft der Mengen und Teilmengen * Erdenteilung. Immanuel Kant vs. Reinhard Mey * Zweiteilung und Dreiteilung. Hendiadyoin als Logik der Gemeinschaft * Abteilung. Vom Limes zum Limen * Spielbeteiligung. Be-dingte Gemeinschaft * Teil. Gemeinschaft als Perlenkette * Mitteilung. Kafer und Mitsein * Gegenteil. Eros und Anteros als Formen der Gemeinschaft * Schicksalszuteilung. Der Mensch auf der Flucht * Vorteil, Nachteil, Bauteil, Bestandteil, Urteil, Losteilung und Teilnahmslosigkeit. Und das ist langst noch nicht alles * Umteilung. Philosophie als Hexengebrau und Gemeinschaft im Auge. (shrink)

The discourse on escaping is primarily directed towards the who of escape. The question of what and how of escaping in its cultural-anthropological significance is usually neglected. The present paper claims to overcome this inadequacy by exploring escape eo ipso and as a spatial-theoretical phenomenon. For this purpose, it is necessary to rethink escape as a triple articulated phenomenological topology based on three vectors: escape as a start, escape as a transition and escape as a destination/refuge. The escape-vectors play the (...) role of symbolic and basic structures which are connected with linguistic and cognitive paradigms. Among the basic figures of escaping, this paper examines escape as a separation, as a non-place and as a fugue; these correspond in turn to the environmental metaphors, first, of the earth as exile, secondly, of the sea and the desert, and finally of the earth as asylum. The multilayered topology of escaping is reconstructed in the interdisciplinary field of spatial theory, of etymology, literature and political philosophy. By examining its spatial-philosophical characteristics, escape emerges as a dynamic phenomenon that can reshape essential concepts and inverse traditional categories of politics. For that reason, escaping determines a philosophically “inverted world” and consequently constitutes an essential source for the future development of cultural-political systems. (shrink)

Kritik: Giovanni Tidona, Gemeinschaften. Figuren der Lebensteiligkeit, Freiburg/München: Karl Alber 2019.

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.

We introduce a sequent calculus B for a new logic, named basic logic. The aim of basic logic is to find a structure in the space of logics. Classical, intuitionistic, quantum and non-modal linear logics, are all obtained as extensions in a uniform way and in a single framework. We isolate three properties, which characterize B positively: reflection, symmetry and visibility. A logical constant obeys to the principle of reflection if it is characterized semantically by an equation binding it with (...) a metalinguistic link between assertions, and if its syntactic inference rules are obtained by solving that equation. All connectives of basic logic satisfy reflection. To the control of weakening and contraction of linear logic, basic logic adds a strict control of contexts, by requiring that all active formulae in all rules are isolated, that is visible. From visibility, cut-elimination follows. The full, geometric symmetry of basic logic induces known symmetries of its extensions, and adds a symmetry among them, producing the structure of a cube.

The first issue of Artificial Intelligence and Law journal was published in 1992. This paper provides commentaries on nine significant papers drawn from the Journal’s second decade. Four of the papers relate to reasoning with legal cases, introducing contextual considerations, predicting outcomes on the basis of natural language descriptions of the cases, comparing different ways of representing cases, and formalising precedential reasoning. One introduces a method of analysing arguments that was to become very widely used in AI and Law, namely (...) argumentation schemes. Two relate to ontologies for the representation of legal concepts and two take advantage of the increasing availability of legal corpora in this decade, to automate document summarisation and for the mining of arguments.

Within the technical frame supplied by the algebraic variety of diagonalizable algebras, defined by R. Magari in [2], we prove the following: Let T be any first-order theory with a predicate Pr satisfying the canonical derivability conditions, including Löb's property. Then any formula in T built up from the propositional variables $q,p_{1},...,p_{n}$ , using logical connectives and the predicate Pr, has the same "fixed-points" relative to q (that is, formulas $\psi (p_{1},...,p_{n})$ for which for all $p_{1},...,p_{n}\vdash _{T}\phi (\psi (p_{1},...,p_{n}),p_{1},...,p_{n})\leftrightarrow \psi (...) (p_{1},...,p_{n})$ ) of a formula $\phi ^{\ast}$ of the same kind, obtained from φ in an effective way. Moreover, such $\phi ^{\ast}$ is provably equivalent to the formula obtained from φ substituting with $\phi ^{\ast}$ itself all the occurrences of q which are under Pr. In the particular case where q is always under Pr in φ, $\phi ^{\ast}$ is the unique (up to provable equivalence) "fixed-point" of φ. Since this result is proved only assuming Pr to be canonical, it can be deduced that Löb's property is, in a sense, equivalent to Gödel's diagonalization lemma. All the results are proved more generally in the intuitionistic case. (shrink)

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.

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.

The search for a synthesis between formalism and constructivism, and meditation on Gödel incompleteness, leads in a natural way to conceive mathematics as dynamic and plural, that is the result of a human achievement, rather than static and unique, that is given truth. This foundational attitude, called dynamic constructivism, has been adopted in the actual development of topology and revealed some deep structures that had remained hidden under other views. After motivations for and a brief introduction to dynamic constructivism, an (...) overview is given of the changes it induces in the practice of mathematics and in its foundation, and of the new results it allows to obtain.

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.

This article models legal interpretation through argumentation and provides a logical analysis of interpretive arguments, their conflicts, and the resulting indeterminacies. Interpretive arguments are modelled as defeasible inferences, which can be challenged and defeated by counterarguments and be reinstated through further arguments. It is shown what claims are possibly (defensibly) or necessarily (justifiably) supported by the arguments constructible from a given interpretive basis, i.e., a set of interpretive canons coupled with reasons for their application. It is finally established under what (...) conditions such arguments provide single outcomes or rather support alternative interpretive conclusions, thus leading to propositions of law whose truth‐value is undetermined.

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.

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.

Ziel des Dialogs Idiota de mente (1450) ist die Zusammenführung der aristotelischen Bestimmung des Intellekts als Formprinzip des Lebens mit der platonisch-augustinischen Idee von der Unsterblichkeit der Seele. Für Cusanus ist die mens (Geist) eine eigene lebendige Substanz: Sie ist für sich selbst seiende Seele als Einheit ihrer Kräfte und das Bild Gottes.
