The book aims at a comprehensive account of the relationship between Wittgenstein s Tractatus Logico-Philosophicus and Russell s philosophy as it developed between 1903 and 1918. The focus is on the central nucleus of the Tractatus, i.e., on its ontology and the picture theory of language. On Russell s side, the multiple-relation theory of judgment has been chosen as the leading theme around which the presentation of several other issues is organized. Whereas the similarity between Russell s and Wittgenstein s (...) problems is pointed out, the deep difference between their solutions is acknowledged, in particular with reference to the opposition between objects and names on the one hand, and facts and propositions on the other.".

Using quantitative methods, we investigate the role of logic in analytic philosophy from 1941 to 2010. In particular, a corpus of five journals publishing analytic philosophy is assessed and evaluated against three main criteria: the presence of logic, its role and level of technical sophistication. The analysis reveals that logic is not present at all in nearly three-quarters of the corpus, the instrumental role of logic prevails over the non-instrumental ones, and the level of technical sophistication increases in time, although (...) it remains relatively low. These results are used to challenge the view, widespread among analytic philosophers and labeled here “prevailing view”, that logic is a widely used and highly sophisticated method to analyze philosophical problems.

There is a rather widespread consensus, among historians of philosophy, concerning the decline of Wittgenstein amid recent analytic philosophy. However, the exact import of such a decline,...

The article investigates what happens when philosophy meets and begins to establish connections with two formal research methods such as game theory and network science. We use citation analysis to identify, among the articles published in Synthese and Philosophy of Science between 1985 and 2021, those that cite the specialistic literature in game theory and network science. Then, we investigate the structure of the two corpora thus identified by bibliographic coupling and divide them into clusters of related papers by automatic (...) community detection. Lastly, we construct by the same bibliometric techniques a reference map of philosophy, on which we overlay our corpora to map the diffusion of game theory and network science in the various sub-areas of recent philosophy. Three main results derive from this study. Philosophers are interested not only in using and investigating game theory as a formal method belonging to applied mathematics and sharing many relevant features with social choice theory, but also in considering its applications in more empirically oriented disciplines such as social psychology, cognitive science, or biology. Philosophers focus on networks in two research contexts and in two different ways: in the debate on causality and scientific explanation, they consider the results of network science; in social epistemology, they employ network science as a formal tool. In the reference map, logic—whose use in philosophy dates back to a much earlier period—is distributed in a more uniform way than recently encountered disciplines such as game theory and network science. We conclude by discussing some methodological limitations of our bibliometric approach, especially with reference to the problem of field delineation. (shrink)

Different interpretations of Bradley’s regress argument are considered. On the basis of textual evidences, it is argued that the most persuasive is the one that sees the argument as primarily addressing the general issue of unity or connectedness.

The essays collected in this volume explore the fundamental issues of philosophical realism, including metaphysical realism. Do things exist and have properties independently of being objects of thought or perception? epistemological realism: Is it possible to know any part of reality in and of itself? and ontological realism: Are there universals?

Gustav Bergmann was, arguably, one of the greatestontologists of the twentieth century. In 2006 and 2007, after aperiod of relative neglect, international conferences devoted solelyto Bergmanns work were held at the University of Iowa in the USA,Universit de Provence in France, and Universit degli Studi diRoma Tre in Italy. The fifteen papers collected in this volume werepresented at the third of these conferences, in Rome, and are here dividedinto three sections: "Categories of a realistic ontology," "World,mind, and relations," and "Metaphysics (...) of space and time".

1. Premesse Questo articolo richiede alcune premesse. Innanzitutto sono opportuni due chiarimenti, o precisazioni, che riguardano il titolo, Il nominalismo di Quine: un argomento circolare. Il primo chiarimento riguarda l’attribuzione a Willard Van Orman Quine di una posizione nominalistica, attribuzione contestabile sotto diversi rispetti. È vero che Quine è comunemente considerato uno dei maggiori esponenti del nominalismo contemporaneo. Tuttavia il termine “nominalismo” può essere inteso i...

Esiste, oltre alle singole cose rosse, la proprietà universale "rosso"? O esistono invece solo le entità individuali e particolari? Come spiegare il fatto che più entità tra loro distinte possono essere tuttavia uguali per un determinato aspetto? E che cos'è che distingue due entità che condividano esattamente le stesse proprietà? Questi sono alcuni dei problemi che costituiscono la questione degli universali e dei particolari, che, a partire dai dialoghi platonici e dalla metafisica di Aristotele, ha sempre rappresentato uno dei nodi (...) centrali dell'ontologia. Di tale questione il libro ripercorre le tappe storiche principali, partendo dalla formulazione che ne fu proposta nell'antichità, esaminando gli importanti e variegati sviluppi medievali, individuandone la presenza talvolta nascosta nella filosofia moderna e ricostruendo i dibattiti della metafisica contemporanea, che ha visto una significativa rinascita di interesse per questi temi, soprattutto nell'ambito della filosofia analitica. -/- (English version) Does there exist, besides single red things, a universal red property? Or are there only individual, particular entities? How does one explain the fact that many distinct entities can be considered the same as regards a specific feature? And what is it exactly that distinguishes two things that share the exact same property? These are some of the questions that involve universals and particulars, a general issue that, ever since Plato's dialogues and Aristotle's Metaphysics, has played a crucial role in ontology. This book outlines the evolution of this issue through its main historical phases, from its initial conception in ancient times, through its medieval development, up to its sometimes hidden presence in modern philosophy. The text also addresses contemporary debates in metaphysics, in which there is a significant revival of interest for this topic, especially in analytical philosophy. (shrink)

This paper studies proof systems for the logics of super-strict implication ST2–ST5, which correspond to C.I. Lewis’ systems S2–S5 freed of paradoxes of strict implication. First, Hilbert-style axiomatic systems are introduced and shown to be sound and complete by simulating STn in Sn and backsimulating Sn in STn, respectively(for n=2,...,5). Next, G3-style labelled sequent calculi are investigated. It is shown that these calculi have the good structural properties that are distinctive of G3-style calculi, that they are sound and complete, and (...) it is shown that the proof search for G3. ST2 is terminating and therefore the logic is decidable. (shrink)

Modal knowledge accounts that are based on standards possible-worlds semantics face well-known problems when it comes to knowledge of necessities. Beliefs in necessities are trivially sensitive and safe and, therefore, trivially constitute knowledge according to these accounts. In this paper, I will first argue that existing solutions to this necessity problem, which accept standard possible-worlds semantics, are unsatisfactory. In order to solve the necessity problem, I will utilize an unorthodox account of counterfactuals, as proposed by Nolan, on which we also (...) consider impossible worlds. Nolan’s account for counterpossibles delivers the intuitively correct result for sensitivity i.e. S’s belief is sensitive in intuitive cases of knowledge of necessities and insensitive in intuitive cases of knowledge failure. However, we acquire the same plausible result for safety only if we reject his strangeness of impossibility condition and accept the modal closeness of impossible worlds. In this case, the necessity problem can be analogously solved for sensitivity and safety. For some, such non-moderate accounts might come at too high a cost. In this respect, sensitivity is better off than safety when it comes to knowing necessities. (shrink)

St. Thomas Aquinas never commented on the Song of Songs. The purpose of this book is to demonstrate, however, that he meditated on it and absorbed it, so that the words of the Song are for him a familiar repertoire and a theological source. His work contains numerous citations of the Song, not counting his borrowings of vocabulary and images from it. In total, there are 312 citations of the Song in Aquinas's corpus, along with citations of the Song that (...) are found in citations that Aquinas makes of other authors (as for example in the Catena aurea). Understanding the purpose and placement of these citations significantly enriches our understanding of Aquinas as a theologian, biblical exegete, and spiritual master. The book contains an Appendix listing and contextualizing each citation. The study of the citations of the Song especially illuminates Aquinas's spiritual doctrine. By citing the Song, Aquinas emphasizes the spiritual life's path of dynamic ascent, through an ever increasing participation in the mystery of the nuptial union of Christ and the Church through love. The Song also highlights the eschatological tension or yearning present in the spiritual life, which is ordered to the fullness of beatific vision. Although Aquinas's theology is highly "intellectual," by citing the Song he brings out the affective character of the spiritual life and conveys the centrality of love in the soul's journey toward Christ. He also draws together contemplation and preaching through his use of the Song. (shrink)

Discrimination is a central epistemic capacity but typically, theories of discrimination only use discrimination as a vehicle for analyzing knowledge. This paper aims at developing a self-contained theory of discrimination. Internalist theories of discrimination fail since there is no compelling correlation between discriminatory capacities and experiences. Moreover, statistical reliabilist theories are also flawed. Only a modal theory of discrimination is promising. Versions of sensitivity and adherence that take particular alternatives into account provide necessary and sufficient conditions on discrimination. Safety in (...) contrast is not sufficient for discrimination as there are cases of safety that are clearly instances of discrimination failure. The developed account of discrimination between objects will be extended to discrimination between kinds and between types. (shrink)

Hassin recently proposed the “Yes It Can” (YIC) principle to describe the division of labor between conscious and unconscious processes in human cognition. According to this principle, unconscious processes can carry out every fundamental high-level cognitive function that conscious processes can perform. In our commentary, we argue that the author presents an overly idealized review of the literature in support of the YIC principle. Furthermore, we point out that the dissimilar trends observed in social and cognitive psychology, with respect to (...) published evidence of strong unconscious effects, can better be explained by the way how awareness is defined and measured in both research fields. Finally, we show that the experimental paradigm chosen by Hassin to rule out remaining objections against the YIC principle is unsuited to verify the new default notion that all high-level cognitive functions can unfold unconsciously.

Vogel argues that sensitivity accounts of knowledge are implausible because they entail that we cannot have any higher-level knowledge that our beliefs are true, not false. Becker and Salerno object that Vogel is mistaken because he does not formalize higher-level beliefs adequately. They claim that if formalized correctly, higher-level beliefs are sensitive, and can therefore constitute knowledge. However, these accounts do not consider the belief-forming method as sensitivity accounts require. If we take bootstrapping as the belief-forming method, as the discussed (...) cases suggest, then we face a generality problem. Our higher-level beliefs as formalized by Becker and Salerno turn out to be sensitive according to a wide reading of bootstrapping, but insensitive according to a narrow reading. This particular generality problem does not arise for the alternative accounts of process reliabilism and basis-relative safety. Hence, sensitivity accounts not only deliver opposite results given different formalizations of higher-level beliefs, but also for the same formalization, depending on how we interpret bootstrapping. Therefore, sensitivity accounts do not fail because they make higher-level knowledge impossible, as Vogel argues, and they do not succeed in allowing higher-level knowledge, as Becker and Salerno suggest. Rather, their problem is that they deliver far too heterogeneous results. (shrink)

According to predictive processing, an increasingly influential paradigm in cognitive science, the function of the brain is to minimize the prediction error of its sensory input. Conceptual engineering is the practice of assessing and changing concepts or word meanings. We contribute to both strands of research by proposing the first cognitive account of conceptual engineering, using the predictive processing framework. Our model reveals a new kind of implementation problem as prediction errors are only minimized if enough agents embrace conceptual changes. (...) This problem can be overcome by emphasizing the importance of social norms and conceptual pluralism. (shrink)

That bootstrapping and Moorean reasoning fail to instantiate persuasive argumentation is an often informally presented but not systematically developed view. In this paper, I will argue that this unpersuasiveness is not determined by principles of justification transmission but by two straightforward principles of rationality, understood as a concept of internal coherence. First, it is rational for S to believe the conclusion of an argument because of the argument, only if S believes sufficiently many premises of the argument. Second, if S (...) doubts that a source O is reliable and believes that information i is delivered by O, then S rationally suspends judgment about the truth of i. This paper aims to accomplish two tasks. First, it provides a thorough analysis of why bootstrapping argumentation is not an instance of rational persuasion. Second, it contains a more general theory about preconditions and limits of persuasive argumentation. (shrink)
