The growing interest in fragmentalism is one of the most exciting trends in philosophy of time and is gradually reshaping the contemporary debate. Providing an extensive interpretation of this view, Samuele Iaquinto and Giuliano Torrengo articulate a novel theory of the passage of time and argue that it is the most effective in vindicating the inherent dynamism of reality. Iaquinto and Torrengo offer the first full-range application of fragmentalism to a number of metaphysical topics, including the open future, causation, the A-theoretic interpretation of special relativity and time travel. The resulting picture, they argue, conveys the potential of a radically new understanding of time.

This paper introduces a new kind of explanation that we describe as ‘purely theoretical’. We first present an example, E, of what we take to be a case of purely theoretical explanation. We then show that the explanation we have in mind does not fit neatly into any of the existing categories of explanation. We take this to give us prima facie motivation for thinking that purely theoretical explanation is a distinctive kind of explanation. We then argue that it can earn its keep via application to two existing literatures: the literature on how we explain the truth of true negative existential propositions and the literature on how we explain the truth of true propositions about the past. We reply to some possible concerns regarding the introduction of purely theoretical explanations. We conclude that there is nothing obviously wrong with them and explore the ramifications for particular debates in metaphysics.

The analysis of the derogatory aspect of slurs has recently aroused interest among philosophers of language. A puzzling element of it is its erratic behaviour in embeddings, for instance negation or belief reports. The derogatory aspect seems sometimes to “scope out” from the embedding to the context of utterance, while at other times it seems to interact with the linguistic constructions in which the slur is implanted. I argue that slurs force us to maintain a kind of semantic indeterminacy which, to my knowledge, has passed largely unnoticed in philosophy of language.

The aim of this paper is to argue that the adoption of an unrestricted principle of bivalence is compatible with a metaphysics that (i) denies that the future is real, (ii) adopts nomological indeterminism, and (iii) exploits a branching structure to provide a semantics for future contingent claims. To this end, we elaborate what we call Flow Fragmentalism, a view inspired by Kit Fine (2005)’s non-standard tense realism, according to which reality is divided up into maximally coherent collections of tensed facts. In this way, we show how to reconcile a genuinely A-theoretic branching-time model with the idea that there is a branch corresponding to the thin red line, that is, the branch that will turn out to be the actual future history of the world.

In this paper, I present a problem for the realist with respect to the institutional sphere, and suggest a solution. Roughly, the problem lies in a contradiction that arises as soon as institutional contexts are allowed to influence the institutional profile of objects and events not only in the present, but also in the past. If such “retroactive enactments” are effective, in order to avoid contradiction the realist seems to have to accept the unpleasant conclusion that institutions can create a past that has never been present. I will defend a solution which involves a distinction between temporal and atemporal types of institutional kinds that has, I maintain, independent interest.

There seems to be a minimal core that every theory wishing to accommodate the intuition that the future is open must contain: a denial of physical determinism (i.e. the thesis that what future states the universe will be in is implied by what states it has been in), and a denial of strong fatalism (i.e. the thesis that, at every time, what will subsequently be the case is metaphysically necessary).1 Those two requirements are often associated with the idea of an objective temporal flow and the non-reality of the future. However, at least certain ways to frame the “openness” intuition do not rely on any of these. Branching Time Theory (BTT) is one such: it is compatible with the denial that time flow is objective and it is couched in a language with a (prima facie) commitment to an eternalist ontology. BTT, though, urges us to resist certain intuitions about the determinacy of future claims, which arguably do not lead either to physical determinism or to fatalism. Against BTT, supporters of the Thin Red Line Theory (TRL) argue that their position avoids determinism and fatalism, while also representing the fact that there is a future which is “special” because it is the one that will be the case. But starting with Belnap and Green 1994, some have objected to the tenability of TRL, mainly on metaphysical grounds. In particular, those argue that “positing a thin red line amounts to giving up objective indeterminism,”2 and that “has unacceptable consequences, ranging from a mistreatment of actuality to an inability to talk coherently about what would have happened had what is going to happen not taken place.”3 In this paper, we wish to reframe the..

Achille Varzi è uno dei maggiori metafisici viventi. Nel corso degli anni ha scritto testi fondamentali di logica, metafisica, mereologia, filosofia del linguaggio. Ha sconfinato nella topologia, nella geografia, nella matematica, ha ragionato di mostri e confini, percezione e buchi, viaggi nel tempo, nicchie, eventi e ciambelle; e non ha disdegnato di dialogare con gli abitanti di Flatlandia, con Neo e con Terminator. Tra le sue opere principali: Holes and Other Superficialities e Parts and Places. The Structures of Spatial Representation, entrambi scritti insieme a R. Casati per MIT Press; Il mondo messo a fuoco, Laterza; e il suo libro più recente: Le tribolazioni del filosofare, con C. Calosi, per Laterza. Da una giornata all’Università di Urbino nasce questa conversazione a molte voci sulla e con la filosofia di Achille C. Varzi. In un dialogo critico al quale l’Autore si presta con generosità e onestà intellettuale, Andrea Borghini, Francesco Calemi, Claudio Calosi, Elena Casetta, Valeria Giardino, Pierluigi Graziani, Patrizia Pedrini, Daniele Santoro e Giuliano Torrengo lo interrogano e mettono alla prova sui temi affrontati, nel corso degli anni, in campi diversi. Il risultato è un percorso che si snoda attraverso molti mondi, dalla logica alla metafisica, dalla filosofia del linguaggio alla filosofia della matematica, dalla mereologia alla filosofia del tempo, spingendosi in qualche caso oltre i confini del saggio filosofico.

What do “existing” and “having existed” mean? The answer to this question depends radically on the metaphysical assumption that we are making about the nature of time. If we take the present to be privileged over other times, then “having existed” is bound to express a notion close to non-existence. If we think that the present has no ontological supremacy over what was and what will be, then the difference between “having existed” and “existing” is bound to be no deeper than the difference between “existing here” and “existing there”. In this article I show that the view to the effect that the present is privileged, i.e. “presentism”, suffers from a fatal problem concerning the present truth of many past-tensed existential statements. Therefore, we had better abandon it in favour of “eternalism” – the rival view to the effect that between “existing” and “having existed” there is no ontological difference.

The moving spotlight account (MS) is a view that combines an eternalist ontology and an A-theoretic metaphysics. The intuition underlying MS is that the present time is somehow privileged and experientially vivid, as if it were illuminated by a moving spotlight. According to MS-theorists, a key reason to prefer MS to B-theoretic eternalism is that our experience of time supports it. We argue that this is false. To this end, we formulate a new family of positions in the philosophy of time, which differ from MS in that, intuitively, they admit a plurality of moving spotlights. We argue that these ‘deviant’ variants of MS cannot be dismissed as conceptually incoherent, and that they are as well-supported by our experience as is MS. One of these variants, however, is consistent with the B-theory. Thus, if our experience of time supports MS, then it supports the B-theory as well.

In this paper, we articulate a version of non-standard A-theory—which we call Flow Fragmentalism—in relation to its take on the issue of supervenience of truth on being. According to the Truth Supervenes on Being (TSB) Principle, the truth of past- and future-tensed propositions supervenes, respectively, on past and future facts. Since the standard presentist denies the existence of past and future entities and facts concerning them that do not obtain in the present, she seems to lack the resources to accept both past and future-tensed truths and the TSB Principle. Contrariwise, positions in philosophy of time that accept an eternalist ontology (e.g., B-theory, moving spotlight, and Fine’s and Lipman’s versions of fragmentalism) allow for a “direct” supervenience base for past- and future-tensed truths. We argue that Flow Fragmentalism constitutes a middle ground, which retains most of the advantages of both views, and allows us to articulate a novel account of the passage of time.

In this paper we discuss two issues addressed by Stanley in How Propaganda Works: the status of slurs (Section 1) and the notion of positive propaganda (Section 2). In particular, in Section 1 we argue contra Stanley that code words like ‘welfare’ are crucially different from slurs in that the association between the lexical item and an additional social meaning is not as systematic as it is for slurs. In this sense, slurs bring about a special kind of propagandistic effect, even if it typically concerns informal contexts rather than public debates. In Section 2, we consider positive propaganda and its relation to emotional effects. For Stanley, positive propaganda relies on the production of emotional effects, feature which risks to erode rational debates even if there is a good purpose behind. Instead, we argue that positive propaganda can work with no appeal to emotions. To this end, we focus on the use of ‘she’ as the default personal pronoun in academic writing and suggest that this measure can count as positive propaganda which rather than eroding rational debates by relying on emotional effects, closely resembles affirmative action aimed at counterbalance a pre-existing form of injustice and inequality.

The goal of this paper is to defend the general tenet that time travelers cannot change the past within B-theoretical models of time, independently of how many temporal dimensions there are. Baron Pacific Philosophical Quarterly, 98, 129–147 offered a strong argument intended to reach this general conclusion. However, his argument does not cover a peculiar case, i.e. a B-theoretical one-dimensional model of time that allows for the presence of internal times. Loss Pacific Philosophical Quarterly, 96, 1–11 used the latter model to argue that time travelers can change the past within such model. We show a way to debunk Loss’s argument, so that the general tenet about the impossibility of changing the past within B-theoretical models is maintained.

Scopo del volume è offrire un’introduzione accessibile e rigorosa ai più recenti sviluppi di una fondamentale branca della filosofia del tempo: la filosofia del futuro. Vengono presentate e discusse alcune delle domande chiave del dibattito contemporaneo, ad esempio: il futuro è già scritto o esistono molti cammini alternativi che il tempo è in grado di imboccare? "Esistere" significa semplicemente essere presenti o ci sono veri e propri oggetti futuri? Siamo davvero liberi di scegliere quali azioni compiere e di modificare il corso degli eventi? Il dibattito intorno alle risposte di volta in volta offerte in filosofia esplora un’intrigante zona d’intersezione tra metafisica, logica ed etica, e interessa discipline diverse, come la fisica, la psicologia e l’economia. Non sorprende dunque che la discussione contemporanea sia oramai tanto intricata da risultare ostica ai non addetti ai lavori. Il volume offre gli strumenti necessari per inquadrare le domande sul futuro nella loro reale complessità concettuale, introducendo tutte le indispensabili nozioni tecniche in un linguaggio chiaro e intuitivo.

As far as our experience goes, we live in a dynamic present. Those two phenomenal features of experience—presentness and dynamism—are obviously connected. However, how they are connected is not obvious at all. In this paper, I criticise the view according to which the former can explain the latter, which I call sophisticated representationalism. My criticism will be based on an ambiguity in the notion of tense found in the philosophical literature, that between the perspectival understanding and the dynamic understanding of tenses. The distinction is not just of independent interest, but it has a role in providing indirect evidence for the claim that the feeling of passage of time should be understood in non-representationalist terms.

I criticize Lockwood’s solution to the “paradoxes” of time travel, thus endorsing Lewis’s more conservative position. Lockwood argues that only in the context of a 5D space-time-actuality manifold is the possibility of time travel compatible with the Autonomy Principle (according to which global constraints cannot override what is physically possible locally). I argue that shifting from 4D space-time to 5D space-time-actuality does not change the situation with respect to the Autonomy Principle, since the shift does not allow us to have a coincidence-free local dynamical theory.

The social world is populated by many entities, such as promises, contracts, presidents, money, debts, and financial crises. Many philosophers regard collective behaviour and attitudes as the ground of social reality. According to this standard view, social ontology is at bottom composed of collective intentions and cooperative behaviours, and that holds both for simple cases concerning small groups and complex institutional structures. In this paper, this view is challenged and an alternative approach is proposed in which the role of collective intentions and cooperative behaviour is very different in (a) small group cases, where it can be seen as the ground of social roles and obligations, and (b) cases concerning complex institutions, in which documents and records of social acts in general are the ground that determines rights, duties, and all other complex status functions.
