We prove that the theory of the extensional compositional truth predicate for the language of arithmetic with \Delta 0 -induction scheme for the truth predicate and the full arithmetical induction scheme is not conservative over Peano Arithmetic. In addition, we show that a slightly modified theory of truth actually proves the global reflection principle over the base theory.

The relationship between philosophy and science has always been complementary. Today, while science moves increasingly fast and philosophy shows some problems in catching up with it, it is not always possible to ignore such relationships, especially in some disciplines such as philosophy of mind, cognitive science, and neuroscience. However, the methodological procedures used to analyze these data are based on principles and assumptions that require a profound dialogue between philosophy and science. Following these ideas, this work aims to raise the (...) problems that a classical connectionist theory can cause and problematize them in a cognitive framework, considering both philosophy and cognitive sciences but also the disciplines that are near to them, such as AI, computer sciences, and linguistics. For this reason, we embarked on an analysis of both the computational and theoretical problems that connectionism currently has. The second aim of this work is to advocate for collaboration between neuroscience and philosophy of mind because the promotion of deeper multidisciplinarity seems necessary in order to solve connectionism’s problems. In fact, we believe that the problems that we detected can be solved by a thorough investigation at both a theoretical and an empirical level, and they do not represent an impasse but rather a starting point from which connectionism should learn and be updated while keeping its original and profoundly convincing core.

The authoress shows a simple way to avoid paradoxical consequences of the Czerniawski's argument.

In our everyday interaction with the environment, we often perceive objects and spaces as opportunities to feel, maintain, enhance, and change our affective states and processes. The concept of affective affordance was coined to accommodate this aspect of ordinary perception and the many ways in which we rely on the material environment to regulate our emo- tions. One natural way to think of affective affordances in emotion regulation is to interpret them as tools for regulating felt affective states. We argue (...) that this way of conceiving of affective affordances is too restrictive. By analyzing the role of expressive properties of objects and spaces in emotion regulation, we show that our environment does not need to elicit felt affective states to regulate our emotions. Thus, we revise the concept of affective affordance to accommodate these cases. This revised concept explains more with less. Hence, it should be preferred in wide-reaching philosophical projects that aim to explain human affectivity as a situated phenomenon. (shrink)

We show that for every countable recursively saturated model M of Peano arithmetic and every subset A⊆M, there exists a full satisfaction class SA⊆M2 such that A is definable in (M,SA) without parameters. It follows that in every such model, there exists a full satisfaction class which makes every element definable, and thus the expanded model is minimal and rigid. On the other hand, as observed by Roman Kossak, for every full satisfaction class S there are two elements which have (...) the same arithmetical type, but exactly one of them is in S. In particular, the automorphism group of a model expanded with a satisfaction class is never equal to the automorphism group of the original model. The analogue of the first result proved here for full satisfaction classes was obtained also by Roman Kossak for partial inductive satisfaction classes. However, the proof relied on the induction scheme in a crucial way, so recapturing the result in the setting of full satisfaction classes requires quite different arguments. (shrink)

Although mathematical philosophy is flourishing today, it remains subject to criticism, especially from non-analytical philosophers. The main concern is that even if formal tools serve to clarify reasoning, they themselves contribute nothing new or relevant to philosophy. We defend mathematical philosophy against such concerns here by appealing to its metaphysical foundations. Our thesis is that mathematical philosophy can be founded on the phenomenological theory of ideas as developed by Roman Ingarden. From this platonist perspective, the “unreasonable effectiveness of mathematics in (...) philosophy”—to adapt Wigner’s phrase—is analogous to that of mathematical explanations in science. As success-criteria for mathematical philosophy, we propose that it should be correct, responsive, illuminating, promising, relevant, and adequate. (shrink)

Harnecker, M. Política y clases sociales en Poulantzas (estudio crítico) -- Poulantzas, N. Sobre el concepto de política.

This chapter describes the concept of enactive memory, which is quite new but increasingly discussed in contemporary philosophy of memory. Although the enactive approach has been used to investigate several memory sys- tems, e.g., procedural memory, episodic mem- ory, and autobiographical memory, this chapter focuses only on the enactive approach to epi- sodic memory because most of the current debate on enactive memory is about this mem- ory system. Section “Introduction” specifies what type of enactive memory is discussed in this (...) chapter. Section “The Concept of Enactive Memory” introduces the concept of enactive memory, clarifies its central theoretical com- mitments and goals, and describes how enactivists have explained episodic remember- ing. Section “The Philosophical Context of Enactive Memory” provides a brief contextu- alization of the enactive approach to memory with respect to approaches and theories with which, for one reason or another, it shares some theoretical insights, like the embodied, the extended, and the distributed approach, and the simulation theory. Section “Forgetting as a Challenge for Enactive Memory” explains why forgetting poses an important explanatory challenge to the enactive approach to memory and describes one philosophical proposal that has been developed to address this challenge. Section “Summary” provides a summary of the chapter, mentions some ongoing projects on enactive memory, and identifies some topics that advocates of the enactive approach to memory may want to investigate in the future.

Let ${\cal T}$ be any of the three canonical truth theories CT^− (compositional truth without extra induction), FS^− (Friedman–Sheard truth without extra induction), or KF^− (Kripke–Feferman truth without extra induction), where the base theory of ${\cal T}$ is PA. We establish the following theorem, which implies that ${\cal T}$ has no more than polynomial speed-up over PA. Theorem.${\cal T}$is feasibly reducible to PA, in the sense that there is a polynomial time computable function f such that for every ${\cal T}$-proof (...) π of an arithmetical sentence ϕ, f(π) is a PA-proof of ϕ.

We introduce a tool for analysing models of $\text {CT}^-$, the compositional truth theory over Peano Arithmetic. We present a new proof of Lachlan’s theorem that the arithmetical part of models of $\text {CT}^-$ are recursively saturated. We also use this tool to provide a new proof of theorem from [8] that all models of $\text {CT}^-$ carry a partial inductive truth predicate. Finally, we construct a partial truth predicate defined for a set of formulae whose syntactic depth forms a (...) nonstandard cut which cannot be extended to a full truth predicate satisfying $\text {CT}^-$.

In Cieśliński (J Philos Logic 39:325–337, 2010), Cieśliński asked whether compositional truth theory with the additional axiom that all propositional tautologies are true is conservative over Peano Arithmetic. We provide a partial answer to this question, showing that if we additionally assume that truth predicate agrees with arithmetical truth on quantifier-free sentences, the resulting theory is as strong as $$\Delta _0$$ Δ 0 -induction for the compositional truth predicate, hence non-conservative. On the other hand, it can be shown with a (...) routine argument that the principle of quantifier-free correctness is itself conservative. (shrink)

This book presents a novel interpretation of Aristotle's account of how shame instils virtue, and defends its philosophical import. Shame is shown to provide motivational continuity between the actions of the learners and the virtuous dispositions that they will eventually acquire.

Do sports fans really care about their team winning? According to several philosophers, the answer is no. Sports fans engage in fictional caring during the match, which involves a game of make-believe that the result is important. We will argue that this account does not provide a full account of the way in which fans relate to the teams they support. For many fans, the team they support forms a core part of their identity. The success or failure of their (...) team impacts the community they are a part of and around which they build a central part of their identity. For these fans, it really does matter whether their team wins or loses. We will finish by articulating a more limited role that fictional caring may play in sports fandom. (shrink)

When the 2022 FIFA Men’s World Cup was awarded to Qatar, it raised a number of moral concerns, perhaps the most prominent of which was Qatar’s woeful record on human rights in the arena of migrant labour. Qatar’s interest in hosting the event is aptly characterised as a case of ‘sportswashing’. The first aim of this paper is to provide an account of the nature of sportswashing, as a practice of using an association with sport, usually through hosting an event (...) or owning a club (such as Newcastle United, owned by Saudi Arabia), to subvert the way that others attend to a moral violation for which the sportswashing agent is responsible. This may be done through distracting away from wrongdoing, minimising it, or normalising it. Second, we offer an account of the distinctive wrongs of sportswashing. The gravest moral wrong is the background injustice which sportswashing threatens to perpetuate. But the distinctive wrongs of sportswashing are twofold: first, it makes participants in sport (athletes, coaches, journalists, fans) complicit in the sportswasher’s wrongdoing, which extends a moral challenge to millions of people involved with sport. Second, sportswashing corrupts valuable heritage associated with sporting traditions and institutions. Finally, we examine how sportswashing ought to be resisted. The appropriate forms of resistance will depend upon different roles people fill, such as athlete, coach, journalist, fan. The basic dichotomy of resistance strategies is to either exit the condition of complicity, for example by refusing to participate in the sporting event, or to modify one’s engagement with the goal of transformation in mind. We recognize this is difficult and potentially burdensome: sports are an important part of many of our lives; our approach attempts to respect this. (shrink)

This book offers readers a pitch side seat to the ethics of fandom. Its accessible six chapters are aimed both at true sports fans whose conscience may be occasionally piqued by their pastime, and at those who are more certain of the moral hazards involved in following a team or sport. Why It's OK to Be a Sports Fan wrestles with a range of arguments against fandom and counters with its own arguments on why being a fan is very often (...) a good thing. It looks at the ethical issues fans face, from the violent or racist behavior of those in the stands, to players' infamous misdeeds, to owners debasing their own clubs. In response to these moral risks, the book argues that by being critical fans, followers of a team or individual can reap the benefits of fandom while avoiding many of the ethical pitfalls. The authors show the value in deeply loving a team, but also how a condition of this value is recognizing that the love of a fan comes with real limits and responsibilities. Key Features Provides an accessible introduction to a key area of the philosophy of sport Closely looks at some of the salient ethical concerns around sports fandom Proposes that the value of community in partisan fandom should not be underestimated as a key feature of the good life Examines how the same emotions and environments that can lead to violence are identical to those that lead to virtuous loyalty Argues for a fan's responsibility in calling out violence or racist behavior from their fellow fans.

The central idea behind this paper is that presuppositions of soft triggers arise from the way our attention structures the informational content of a sentence. Some aspects of the information conveyed are such that we pay attention to them by default, even in the absence of contextual information. On the other hand, contextual cues or conversational goals can divert attention to types of information that we would not pay attention to by default. Either way, whatever we do not pay attention (...) to, be it by default, or in context, is what ends up presupposed by soft triggers. This paper attempts to predict what information in the sentence is likely to end up being the main point (i.e. what we pay attention to) and what information is independent from this, and therefore likely presupposed. It is proposed that this can be calculated by making reference to event times. The notion of aboutness used to calculate independence is based on that of Demolombe and Fariñas del Cerro (In: Holdobler S (ed) Intellectics and computational logic: papers in honor of Wolfgang Bibel, 2000).

This book supports a version of the trope-bundle view of individual substances matching also with a coherent account of change, individuation and individual essences. In particular, it is argued that qualitative individuation and qualitative individual essences can be tackled within the frames of a trope account. The adoption of a trope BT together with the individuation of tropes via the bearer substance might create the feeling of circularity since tropes and substances seem mutually to individuate each other. The novel solution (...) to the problem developed here consists in showing that the individuation of concrete individual substances is independent, in crucial respects, from the fact that they are construed as bundles of tropes. Apart from metaphysician colleagues, the book is recommended for advanced students in analytic metaphysics. (shrink)

¿Qué tenemos en común y qué nos separa de los animales? ¿Somos un animal más? Las humanidades clásicas, basadas en el excepcionalismo humano, han dado paso a las posthumanidades, que incluyen los estudios animales, así como otras perspectivas que desafían la noción tradicional del sujeto humano, como los estudios de género, poscoloniales y decoloniales, la ecocrítica o la teoría queer. Pensarnos en nuestra relación con los animales tiene consecuencias filosóficas en ámbitos como la ciencia, los afectos, el trabajo y el (...) desarrollo de políticas concretas de salud y de alimentación; todas ellas, zonas de contacto entre humanos y animales. Sobre estos encuentros, aunque nunca reparemos en ello, edificamos nuestro mundo. Este ensayo imprescindible aglutina parte de los conocimientos desarrollados hasta ahora por quienes se han acercado a la relación humano-animal, y los vincula con la historia, los movimientos políticos y sociales, las nuevas concepciones del género, de la ciencia y del conocimiento. Los argumentos, contradicciones, contextos e incluso tabúes que acoge este debate interdisciplinar ayudan a imaginar y a matizar unos presupuestos éticos posibles sobre los que replantear nuestra relación con los animales y, en último término, con nosotros mismos.

Aristotle ’s claim that we become virtuous by doing virtuous actions raises a familiar problem: How can we perform virtuous actions unless we are already virtuous? I reject deflationary accounts of the answer given in _Nicomachean Ethics_ 2.4 and argue instead that proper habituation involves doing virtuous actions with the right motive, i.e. for the sake of the noble, even though learners do not yet have virtuous dispositions. My interpretation confers continuity to habituation and explains in a non-mysterious way how (...) we become virtuous by doing virtuous actions in the right way. (shrink)

Some presuppositions are easier to cancel than others in embedded contexts. This contrast has been used as evidence for distinguishing two fundamentally different kinds of presuppositions, ‘soft’ and ‘hard’. ‘Soft’ presuppositions are usually assumed to arise in a pragmatic way, while ‘hard’ presuppositions are thought to be genuine semantic presuppositions. This paper argues against such a distinction and proposes to derive the difference in cancellation from inherent differences in how presupposition triggers interact with the context: their focus sensitivity, anaphoricity, and (...) question–answer congruence properties. The paper also aims to derive the presuppositions of additive particles such as too, also, again, and of it-clefts. (shrink)

Ali Enayat had asked whether two halves of Disjunctive Correctness ([Formula: see text]) for the compositional truth predicate are conservative over Peano Arithmetic (PA). In this paper, we show that the principle “every true disjunction has a true disjunct” is equivalent to bounded induction for the compositional truth predicate and thus it is not conservative. On the other hand, the converse implication “any disjunction with a true disjunct is true” can be conservatively added to [Formula: see text]. The methods introduced (...) here allow us to give a direct nonconservativeness proof for [Formula: see text]. (shrink)

Marta Faustino and Gianfranco Ferraro present a collection of essays by esteemed academics on the ethical and political questions present in Michel Foucault's late work. As one of the most important and controversial thinkers of the twentieth century, the philosopher's last works are at the centre of much current academic research and debate. Comprising 15 essays written by specialists on Foucault's thought from 10 different countries, the perspectives offered by the contributors and the thinker himself can help us to (...) unravel modernity and give us the tools to understand and ethically and politically transform our present.

This article explores the possibilities offered by Collins’ model of interaction rituals to an understanding of the emotional dynamics of art auctions. It argues that whilst it explains how the art object becomes the focus of attention, and thus the repository of solidarity and emotional energy, it also obliterates some of the institutional aspects of the auction market that can influence such outcomes. It discusses the need to include an examination of the specific practices of auction houses operating in an (...) international market in their capacity to target specific audiences for their sales.

Janina Hosiasson-Lindenbaum is a known figure in philosophy of probability of the 1930s. A previously unpublished manuscript fills in the blanks in the full picture of her work on inductive reasoning by analogy, until now only accessible through a single publication. In this paper, I present Hosiasson’s work on analogical reasoning, bringing together her early publications that were never translated from Polish, and the recently discovered unpublished work. I then show how her late work relates to Rudolf Carnap’s approach to (...) “analogy by similarity” developed in the 1960s. Hosiasson turns out to be a predecessor of the line of research that models analogical influence as inductive relevance. A translation of Hosiasson’s manuscript concludes the paper. (shrink)

This volume explores the role and status of phenomena such as feelings, values, willing, and action in the domain of perception and (social) cognition, as well as the way in which they are related. In its exploration, the book takes Husserl's lifelong project Studien zur Struktur des Bewusstseins (1909-1930) as its point of departure, and investigates these phenomena with Husserl but also beyond Husserl. Divided into two parts, the volume brings together essays that address the topics from different phenomenological, philosophical, (...) and psychological perspectives. They discuss Husserl's position in dialogue with historical and recent philosophical and psychological debates and develop phenomenological accounts and descriptions with the help of Geiger, Heidegger, Merleau-Ponty, Plessner, Sartre, Scheler, Schopenhauer, and Reinach.

This paper examines a little studied type of perspective shift that I call protagonist projection, following Holton :625–628, 1997). PP is a way of describing the mental state of a protagonist that conveys, to some extent, her perspective. Similarly to its better known cousin free indirect discourse, the shift in perspective is achieved without an overt operator. Unlike FID, PP is not based on a presumed speech-act of a protagonist. Rather, it gives a linguistic form to pre-verbal perceptual content, sensations, (...) feelings or implicit beliefs. I propose to analyse PP in a bi-contextual framework, extending Eckardt’s approach to FID. Under the resulting analysis, FID and PP are two instances of a more general category of perspective shift.

Nursing has a considerable history of theory development but has consistently struggled to reconcile theoretical reality and practice realities. Many authors have attempted to reconcile what has been called the “theory–practice gap,” but the space where these two realities enmesh has remained problematic and contentious (Aimei, Macau Journal of Nursing, 14, 2015, 13; Factor, Matienzo, & de Guzman, Nurse Education Today, 57, 2017, 82). The idea of the theory–practice gap has a significant history in nursing, but also continues to have (...) a significant presence within nursing literature and mythology up to the present (Aimei, Macau Journal of Nursing, 14, 2015, 13). In this paper, the space between theoretic reality and practice reality, as evidenced by the theory–practice gap, will be examined. A Heideggerian perspective of “dwelling” (Heidegger, 1971, Poetry, language, thought, New York, NY: Harper Colophon) will be used as a guiding discourse to move nursing away from this classic tension between theory and practice, towards a perspective where theory and practice are woven together as part of one reality.

We introduce a principle of local collection for compositional truth predicates and show that it is arithmetically conservative over the classically compositional theory of truth. This axiom states that upon restriction to formulae of any syntactic complexity, the resulting predicate satisfies full collection. In particular, arguments using collection for the truth predicate applied to sentences occurring in any given (code of a) proof do not suffice to show that the conclusion of that proof is true, in stark contrast to the (...) case of the induction scheme. We analyse various further results concerning end-extensions of models of compositional truth and the collection scheme for the compositional truth predicate. (shrink)

The specific role of empeiria in Aristotle’s ethics has received much less attention than its role in his epistemology, despite the fact that Aristotle explicitly stresses the importance of empeiria as a requirement for the receptivity to ethical arguments and as a source for the formation of phronêsis.1 Thus, while empeiria is an integral part of all explanations that scholars give of the Aristotelian account of the acquisition of technê and epistêmê, it is usually not prominent in explanations of the (...) acquisition of phronêsis.2 The abundant mentions of empeiria in Aristotle’s ethical treatises are often eclipsed in the secondary literature...

In what ways and how far does virtue shield someone against suffering evils? In other words, how do non-moral evils affect the lives of virtuous people and to what extent can someone endure evils while staying happy? The central purpose of this chapter is to answer these questions by exploring what Aristotle has to say about the effects of evils in human well-being in general and his treatment of extreme misfortunes.

In March 2016, DeepMind's computer programme AlphaGo surprised the world by defeating the world‐champion Go player, Lee Sedol. AlphaGo exhibits a novel, surprising and valuable style of play and has been recognised as “creative” by the artificial intelligence (AI) and Go communities. This article examines whether AlphaGo engages in creative problem solving according to the standards of comparative psychology. I argue that AlphaGo displays one important aspect of creative problem solving (namely mental scenario building in the form of Monte Carlo (...) tree search), while lacking another (domain generality). This analysis has consequences for how we think about creativity in humans and AI. (shrink)

This paper is a follow-up to [4], in which a mistake in [6] was corrected. We give a strenghtening of the main result on the semantical nonconservativity of the theory of PT−with internal induction for total formulae${$, denoted by PT−in [9]). We show that if to PT−the axiom of internal induction forallarithmetical formulae is added, then this theory is semantically stronger than${\rm{P}}{{\rm{T}}^ - } + {\rm{INT}}\left$. In particular the latter is not relatively truth definable in the former. Last but not (...) least, we provide an axiomatic theory of truth which meets the requirements put forward by Fischer and Horsten in [9]. The truth theory we define is based on Weak Kleene Logic instead of the Strong one. (shrink)
