*I am very pleased to be able to contribute this paper to a festschrift for Andrea Bonomi. This is not however, the paper I really wanted to write; I would have much rather have contributed a paper comparing the pianistic styles of Lennie Tristano and Bill Evans, which I think Andrea would have found much more fascinating than an essay devoted to an understanding of Frege’s thinking. But I do not totally despair. Andrea’s first paper published in English was (...) entitled “On the Concept of Logical Form in Frege,” so perhaps I can maintain some hope that this paper will appeal to lingering interests that Andrea wrote of in the past. I would like to thank Johannes Brandl, Ben Caplan, Bill Demopoulos, Bob Fiengo, Mark Kalderon, Patricia Marino, Gila Sher, Michael Thau, Dan Vest and especially Aldo Antonelli for very helpful discussion.

is accounted for, among other things, in terms of particular relations between events (or states1) and places or times. Roughly speaking, an event α is said to occur in a place p (or interval t) if the spatial (temporal) extension of α is located in p (or t). Let the predicate ‘Occ’ denote such a relation. From this point of view, part of the content of the above sentences can be associated, respectively, with formulas such as.

According to the actualist view, what is essential to the truth conditions of a future-tensed sentence ‘it will be the case that ϕ’ is reference to the unique course of events that will become actual. On the other hand, the modal view has it that the truth conditions of such a sentence require that the truth of ϕ be already “settled” at the time of utterance, where “being settled at time t” is defined by universal quantification over a domain of (...) courses of events, the futures compatible with what has happened up to time t. On the proposal we discuss in this paper, the actualist view and the modal view are seen as two related attitudes that speakers can have when they evaluate future-tensed sentences, and the corresponding interpretations undergo a unified semantic treatment based on a contextual notion of settledness. A central feature of our approach is a dynamic view of contexts of utterance, whereby the world of the utterance is not fixed once and for all, as different worlds, by the passing of time, can play this role in turn. Finally, one major goal of the paper is to show how the unified analysis we propose accounts for a particularly interesting interpretation of future-tensed sentences, often referred to as ‘epistemic reading’.

In communicative exchanges one of the most familiar phenomena is _accommodation_, which enables the addressee to incorporate a missing piece of information into her own view of the common ground. A less familiar, but equally important, phenomenon is what I call _discommodation_, whose main feature consists in the fact that the missing piece of information, although essential to the comprehension of the utterance, _cannot_ be shared by the addressee because it sounds problematic or even false to her. In such cases (...) it is possible to open a ‘presuppositional slot’ to take into account the assumptions that serve to select the reference of the noun phrase, but that are not incorporated into the revised context. One of the main purposes of the paper is to propose a definition of truth that does not ignore the role of discommodation when different views of the common ground are involved. 1. (shrink)

Can stable regularities be explained without appealing to governing laws or any other modal notion? In this paper, I consider what I will call a ‘Humean system’—a generic dynamical system without guiding laws—and assess whether it could display stable regularities. First, I present what can be interpreted as an account of the rise of stable regularities, following from Strevens [2003], which has been applied to explain the patterns of complex systems (such as those from meteorology and statistical mechanics). Second, since (...) this account presupposes that the underlying dynamics displays deterministic chaos, I assess whether it can be adapted to cases where the underlying dynamics is not chaotic but truly random—that is, cases where there is no dynamics guiding the time evolution of the system. If this is so, the resulting stable, apparently non-accidental regularities are the fruit of what can be called statistical necessity rather than of a primitive physical necessity. (shrink)

Leopold first discusses the conservation of natural resources in the southwestern United States in economic tenns, stressing, in particular, erosion and aridity. He then concludes his analysis with a discussion of the moral issues involved, developing his general position within the context of P. D. Ouspenky’s early philosophy of organism.

unified treatment of both (families of) interpretations is based on a revised notion of settledness. The main features of this approach are the following: (i) in branching structures, a world can be represented not by a single course of events, but by a node u in the tree, where u itself is seen as the cluster of courses of events passing through it; (ii) the utterance time is uniquely fixed; (iii) the utterance world is not uniquely fixed; (iv) because of (...) (iii), an utterance-event is associated not to a single context, but to a plurality of contexts, depending on which world we are considering as the utterance world. As a consequence, if a future-tensed sentence φ is uttered at u and its truth (falsehood) is already a settled issue at u itself, then the sentence is true (false) at u; otherwise the sentence is neither true nor false at u and, to get a definite truth value, we must wait until settledness is reached in a different context. Since what is crucial, in both cases, is the reference to a given state of information, such a treatment can be extended to other intriguing uses of the future tense, starting from the epistemic reading. These uses will be topic of a related paper. (shrink)

Since there are independent reasons for associating the habitual reading of the imperfective, in Italian, to a logical form based on universal or generic quantification, the purpose of Part I is to see how this kind of semantical structure accounts for another important interpretation of the imperfective: the progressive reading. And since in some particular cases the imperfective can also have a marginal interpretation which can be assimilated to a perfective effect (it is the so-called “narrative” reading), a further problem (...) is how to provide a reasonable explanation for this phenomenon too. If one considers the co-occurrence of the imperfective with different event predicates (in particular, accomplishments and achievements) it is possible to show that, with some minimal assumptions, the theoretical framework under discussion correctly predicts the following facts, which represent a crucial, but puzzling, characteristic of the imperfective in Italian: (i) activities allow for the progressive reading of the imperfective, but not the “narrative” reading; (ii) with achievements we have the opposite situation; (iii) accomplishments are compatible with both these readings. From this point of view, the semantic properties of the progressive reading of the imperfective are quite distinct from those of the perifrasi progressiva, which is the specialized form used in Italian to express the progressive meaning. Part II, which addresses the issue of the intensional character of both forms of the progressive, is more problematic, in the sense that it takes into consideration a possible extension of the theoretical framework presented in Part I. First of all I discuss some examples which clearly show that the perifrasi progressiva calls for some sort of “branching” representation of time, for it crucially refers to future courses of events which are not realized in the real world. On the other hand, since similar examples can be found in the case of the progressive reading of the imperfective, the main problem is represented by the fact that the kind of logical form under discussion is not completely adequate to account for such intensional phenomena..

In this paper we present a category equivalent to that of tense Nelson algebras. The objects in this new category are pairs consisting of an IKt-algebra and a Boolean IKt-congruence and the morphisms are a special kind of IKt-homomorphisms. This categorical equivalence permits understanding tense Nelson algebras in terms of the better–known IKt-algebras.

Measurement is a process aimed at acquiring and codifying information about properties of empirical entities. In this paper we provide an interpretation of such a process comparing it with what is nowadays considered the standard measurement theory, i.e., representational theory of measurement. It is maintained here that this theory has its own merits but it is incomplete and too abstract, its main weakness being the scant attention reserved to the empirical side of measurement, i.e., to measurement systems and to the (...) ways in which the interactions of such systems with the entities under measurement provide a structure to an empirical domain. In particular it is claimed that (1) it is on the ground of the interaction with a measurement system that a partition can be induced on the domain of entities under measurement and that relations among such entities can be established, and that (2) it is the usage of measurement systems that guarantees a degree of objectivity and intersubjectivity to measurement results. As modeled in this paper, measurement systems link the abstract theory of measuring, as developed in representational terms, and the practice of measuring, as coded in standard documents such as the International Vocabulary of Metrology.

The aim of this paper1 is to provide a unified semantic analysis for three important readings of the Italian Imperfetto (and Presente): the PROGressive, the HABitual, and the FUTurate reading. To highlight the role of the utterance context in setting the relevant parameters of interpretation, explicit temporal adverbials are left out of the scene and prominence is given to the situations where the context provides the temporal information required to discriminate between alternative readings, by exploiting a single logical form. The (...) paper is organized as follows. After a short presentation of the data (sect. 1), in the second section I discuss some intuitive features of imperfectivity by focusing on the fact that the conclusion of an event or series of events is left open. This indeterminacy with respect to a given perspective point is formalized in the third section of the paper by resorting to a branching time model. In the third section a unitary treatment (based on the derivation of a single logical form) is proposed for the three main readings of tenses such as the Presente and the Imperfetto and for an intriguing side effect that, in some particular circumstances, makes a "perfective" reading possible. Since the context has a key role in this reconstruction of imperfectivity, the last section of the paper is devoted to the consideration of the temporal parameters to which the evaluation of an utterance is relativized.

In this paper I examine the testimonium of Aristotle’s Rhetoric concern­ing Diogenes the Cynic. This piece of evidence is the most ancient source of Diogenes and proves that Aristotle was familiar with his writings. I also study the testimonium on Diogenes that is hand­ed down by Theophrastus, which confirms the interest of the ancient Peripatos in this philosopher. Finally, I examine a passage of Book 1 of the Politics where Aristotle refers to the thesis on the aboli­tion of money. I (...) argue that such a thesis could be ascribed to Diogenes. In particular, I attempt to demonstrate that several theses of political philosophy put forward by Diogenes should be considered as constitut­ing a polemical overthrow of the corresponding theses of Aristotle in Book 1 of his Politics.

We are at the moment experiencing renewed interest in the life and work of Aldo Capitini, the Italian philosopher of nonviolence, who was born in Perugia in 1899 and died there in 1968. Conferences, publications, and meetings are drawing the Italian public's attention to his pure lifestyle, deeply marked first by the courageous choice to oppose fascism, then by the long period during which he was marginalized by the university world and official culture; but attention has also been drawn (...) to his numerous writings (from his Elementi di una esperienza religiosa, published in 1937 at the height of the fascist regime, with the help of Benedetto Croce, to Religione aperta, one of the last books to be placed on the Index by the Catholic Church, and finally the essay Attraverso due terzi del secolo, which appeared posthumously in Guido Calogero's journal La Cultura), and to his tireless activity as the driving force behind movements and initiatives (it was Capitini, amongst others, who organised the first peace march from Perugia to Assisi in 1961).

It is not uncommon in the history of science and philosophy to encounter crucial experiments or crucial objections the truth-value of which we are ignorant, that is, about which we suspend judgment. Should we ignore such objections? Contrary to widespread practice, I show that in and only in some circumstances they should not be ignored, for the epistemically rational doxastic attitude is to suspend judgment also about the hypothesis that the objection targets. In other words, suspension of judgment “propagates” from (...) the crucial objection to the hypothesis. In this paper I study under which conditions this phenomenon occurs, and discuss its significance for the topics of skepticism, scientific realism, and peer disagreement. (shrink)

In this paper we aim to show an intrinsic contradiction of contemporary Metaphysical Realism by focusing on the relation between the subject and the object. Metaphysical Realism considers facts and objects as being empirical, and therefore they are considered in relation to the subject, while at the same time facts are assumed to belong to an autonomous and independent reality. However, if a real object is considered to be independent from the subject, once it enters in a relation with the (...) latter, a real object must undergo an intrinsic transformation. However, since an object cannot avoid this transformation then recovering the real or “absolute” object from the perceived object is not possible. In this way, the inherent contradiction of the “absolute” as being determined, i.e., defined by virtue of a limit, is revealed. (shrink)

In our paper, monadic modal pseudocomplemented De Morgan algebras are considered following Halmos’ studies on monadic Boolean algebras. Hence, their topological representation theory is used successfully. Lattice congruences of an mmpM is characterized and the variety of mmpMs is proven semisimple via topological representation. Furthermore and among other things, the poset of principal congruences is investigated and proven to be a Boolean algebra; therefore, every principal congruence is a Boolean congruence. All these conclusions contrast sharply with known results for monadic (...) De Morgan algebras. Finally, we show that the above results for mmpM are verified for monadic tetravalent modal algebras.

Human coalitions frequently persist through multiple, overlapping membership generations, requiring new members to cooperate and coordinate with veteran members. Does the mind contain psychological adaptations for interacting within these intergenerational coalitions? In this paper, we examine whether the mind spontaneously treats newcomers as a motivationally privileged category. Newcomers—though capable of benefiting coalitions—may also impose considerable costs (e.g., they may free ride on other members, they may be poor at completing group tasks). In three experiments we show (1) that the mind (...) categorizes coalition members by tenure, including newcomers; (2) that tenure categorization persists in the presence of orthogonal and salient social dimensions; and (3) that newcomers elicit a pattern of impressions consistent with their probable ancestral costs. These results provide preliminary evidence for a specialized component of human coalitional psychology: an evolved concept of newcomer. (shrink)

Gupta's book [9] contains a theory of modal logic that is closely related to my modal language ML v [2], and his theory is used to treat some interesting philosophical problems. Hence, it is natural for me to review this valuable book and to concentrate on its logics, the more so as its use has already been spoken of and appreciated by Kapitan [10], although I cannot but share his appreciation.

This article demonstrates the importance of making explicit different conceptions of movement for the philosophy of sport. In addition to the mechanistic and the Aristotelian approaches, this article presents a third, underexplored view of movement, namely that of Lucretius as interpreted by Karl Marx and Michel Serres. By exploring the similarities between Marx’s motion of repulsion and Serres’s turbulent flux, it will be argued that a Lucretian view offers a philosophy of movement that uniquely does not rely on stasis. This (...) Lucretian perspective is illustrated through Serres’s elaborations on the body and sport. It is concluded that sport is not primarily a rational, rule-guided practice but arises from moving and sensuous bodies that are always deviating from their standard trajectory. (shrink)

Este artigo se propõe a refletir sobre um leque de conceitos inerentes à alegria por meio de figuras que encarnam a estética da sobra, neste caso, o bobo e o palhaço. Dos gregos até o final do século 19, a filosofia permaneceu a pensar o que é sério. Em 1677, com a publicação de Ética, Baruch Spinoza pensou os afetos, um deles, a alegria, ainda que a tenha pensado com a retidão de um geômetra. A escrita spinoziana é o sério (...) que pensa a alegria. Somente na segunda metade do século 19, Friedrich Nietzsche alegra a escrita filosófica. Em um mundo onde crianças cada vez mais ignoram o sentido do bobo e do palhaço para a vida, refletir sobre a alegria neste artigo é tentar devolver a essa palavra sua profunda originalidade, sentido ausente em dias hodiernos.

This paper offers a diachronic reconstruction of MacCormick's theory of law and legal argumentation: In particular, two related points will be highlighted in which the difference between the perspective upheld in Legal Reasoning and Legal Theory and the later writings is particularly marked. The first point concerns MacCormick's gradual break with legal positivism, and more specifically the thesis that the implicit pretension to justice of law proves legal positivism false in all its different versions. The second point concerns MacCormick's acceptance (...) of the one-right-answer thesis and the consequent thinning of the differences between MacCormick's theory of legal reasoning and that of Ronald Dworkin and of Robert Alexy. The intent, however, is not only to describe this change in MacCormick's thought, but also to attempt a defence of the original view that we find in Legal Reasoning and Legal Theory. (shrink)

Abstract.The aim of this paper is to examine the work of Tschirnhaus, La Hire and Leibniz on the theory of caustics, a subject whose history is closely linked to geometrical optics. The curves in question were examined by the most eminent mathematicians of the 17th century such as Huygens, Barrow and Newton and were subsequently studied analytically from the time of Tschirnhaus until the 19th century.Leibniz was interested in caustics and the subject probably inspired him in his discovery of the (...) concept of envelopes of lines.

The algorithm has become an increasingly important concept in understanding human behavior in recent years. In the case of sport, human bodies are seen as superficial to the driving force of the algorithm, whether it be genetic, behavioral or surveillance-technological algorithms (Harari Citation2015, 2020; Zuboff Citation2019). However, the French mathematician and philosopher Michel Serres (1930–2019) structurally relate algorithms to sports and bodily experience at multiple places in his oeuvre. According to Serres, sport actually enables us to reprogram and rewrite our (...) behavior, moods and thoughts, and therefore modifies our algorithmic status (Serres Citation1999, Citation2019). Against deterministic conceptions of the body, Serres argues that human bodies possess a ‘metamorphic’ nature that is similar to the procedural character of computer programs. This paper investigates the relationship between the algorithm and bodily existence through a reading of both Harari and Serres on sport. It will be argued that, against deterministic conceptions of the algorithm, the algorithm can actually broaden an understanding of the role of sports and physical activity. (shrink)

The IKt-algebras that we investigate in this paper were introduced in the paper An algebraic axiomatization of the Ewald’s intuitionistic tense logic by the first and third author. Now we characterize by topological methods the subdirectly irreducible IKt-algebras and particularly the simple IKt-algebras. Finally, we consider the particular cases of finite IKt-algebras and complete IKt-algebras.

English summary: Aldo Giorgio Gargani innovates in his use of Wittgensteinian concepts to argue that the formation of scientific and philosophical knowledge is not a linear progression, but a collection of instruments or conceptual and behavioral models, decisional procedures that are born of the different forms of human life as extensions of their anthropological contexts. Through this book Gargani demonstrates how Wittgensteins thinking can be used a truly efficient toolbox. French description: Aldo Giorgio Gargani (1933-2009) fait dans ce (...) livre un usage novateur des concepts wittgensteiniens pour soutenir que la formation du savoir scientifique et philosophique n'est pas une progression lineaire, cumulative et definitive de techniques cognitives: le savoir est plutot un recueil d'instruments, d'habitus conceptuels, de modeles comportementaux, de conduites operationnelles et de procedures decisionnelles qui naissent des formes de vie des hommes, en tant qu'extensions de leurs contextes anthropologiques. Si l'expression savoir sans fondements est maintenant tres repandue dans les sciences humaines, c'est Gargani qui a magistralement elabore toutes les consequences de cette idee, et son livre est l'analyse la plus riche de ces rituels epistemologiques qui decoulent de notre agir humain, lui-meme depourvu de fondements. A travers ce livre on voit comment la pensee de Wittgenstein peut etre utilisee comme une boite a outils veritablement efficace. (shrink)

In the following interview with Manlio Iofrida, Aldo Giorgio Gargani retraces the fundamental moments and key phases of his intellectual development: his early childhood and adolescence in Genoa, strongly marked by the influence of his artist father and of the social context of the immediate post-war situation; his studies at the Scuola Normale Superiore in Pisa, and subsequently at the University of Oxford, which resulted to his first book on Wittgenstein; the achievement during the 1960s of a distinctive philosophical (...) position of his own, reflected in the publication of the book Il sapere senza fondamenti [Knowledge without Foundations]; the renewal of philosophical culture in Italy in the 1980s and 1990s, in which Gargani himself was one of the main protagonists; the return to an engagement with Wittgenstein, after a period in which he had dedicated himself principally to literary questions and concerns, one pursued specifically in the context of the new issues raised at the beginning of the 21st century. This historical and autobiographical reconstruction of his intellectual career is accompanied at every turn by philosophical reflections on our contemporary situation and by specific critical responses to other contemporary philosophical trends and developments: the interview thus constitutes a telling summation of the fundamental themes and aspects of the author’s thought in general.

The Choquet expected utility model deals with nonadditive probabilities (or capacities). Their dependence on the information the decision-maker has about the possibility of the events is taken into account. Two kinds of information are examined: interval information (for instance, the percentage of white balls in an urn is between 60% and 100%) and comparative information (for instance, the information that there are more white balls than black ones). Some implications are shown with regard to the core of the capacity and (...) to two additive measures which can be derived from capacities: the Shapley value and the nucleolus. Interval information bounds prove to be satisfied by all probabilities in the core, but they are not necessarily satisfied by the nucleolus (when the core is empty) and the Shapley value. We must introduce the constrained nucleolus in order for these bounds to be satisfied, while the Shapley value does not seem to be adjustable. On the contrary, comparative information inequalities prove to be not necessarily satisfied by all probabilities in the core and we must introduce the constrained core in order for these inequalities be satisfied. However, both the nucleolus and the Shapley value satisfy the comparative information inequalities, and the Shapley value does it more strictly than the nucleolus. (shrink)

In this paper we investigate the class of MV-algebras equipped with two quantifiers which commute as a natural generalization of diagonal-free two-dimensional cylindric algebras. In the 40s, Tarski first introduced cylindric algebras in order to provide an algebraic apparatus for the study of classical predicate calculus. The diagonal–free two-dimensional cylindric algebras are special cylindric algebras. The treatment here of MV-algebras is done in terms of implication and negation. This allows us to simplify some results due to Di Nola and Grigolia (...) :125–139, 2004) related to the characterization of a quantifier in terms of some special sub-algebra associated to it. On the other hand, we present a topological duality for this class of algebras and we apply it to characterize the congruences of one algebra via certain closed sets. Finally, we study the subvariety of this class generated by a chain of length n + 1. We prove that the subvariety is semisimple and we characterize their simple algebras. Using a special functional algebra, we determine all the simple finite algebras of this subvariety. (shrink)

La ricerca qui proposta si rivolge al programma di radicale naturalizzazione della mente e, in particolare, alla posizione del monismo materialistico che esso produce. L’articolo si propone di individuare gli assunti fondamentali sui quali tale programma poggia. Un primo assunto identificato e discusso criticamente all’interno del lavoro concerne una concezione corrispondentista della verità. Un secondo assunto fa riferimento ad una concezione secondo la quale lo studio della mente si riduce all’individuazione di relazioni causali e leggi che regolano processi meccanici, mentre (...) si possono considerare scientifiche solo quelle forme di indagine fondate sul principio di chiusura del mondo fisico. L’analisi si conclude sottolineando come il presupposto più significativo si riveli essere la negazione della soggettività e della coscienza, la quale viene ridotta/ricondotta a operazioni inconsce e inintelligenti. In problema rincontrato a questo rispetto è identificato nel fatto di non fare valere la fondamentale distinzione teoretica tra condizione empirica e condizione di intelligibilità. (shrink)

The main aim of this article is to offer a sociological concept of crisis that, defined as the expected yet non-lineal outcome of the internal dynamics of modern societies, builds on the synergies between critical theory and systems theory. It contends that, notwithstanding important differences, both traditions concur in addressing crises as a form of self-reproduction of social systems as much as a form of engagement with the complexities and effects of such processes of reproduction. In order to make our (...) comparison exhaustive, this article explores critical and systems theories’ notions of crisis at three levels: (1) their conceptual delimitation of crises; (2) their methodological proposals to empirically observe crises; and (3) their normative attempts to contribute to their resolution. As crises remain a distinctive structural feature of the social world and a rich source of knowledge about it, reflexivity must be seen as a crucial form of engagement with the negative expressions of social life itself.
