In the present paper we use the theory of exact completions to study categorical properties of small setoids in Martin-Löf type theory and, more generally, of models of the Constructive Elementary Theory of the Category of Sets, in terms of properties of their subcategories of choice objects. Because of these intended applications, we deal with categories that lack equalisers and just have weak ones, but whose objects can be regarded as collections of global elements. In this context, we study the (...) internal logic of the categories involved, and employ this analysis to give a sufficient condition for the local cartesian closure of an exact completion. Finally, we apply this result to show when an exact completion produces a model of CETCS. (shrink)

C-systems were defined by Cartmell as models of generalized algebraic theories. B-systems were defined by Voevodsky in his quest to formulate and prove an initiality conjecture for type theories. They play a crucial role in Voevodsky’s construction of a syntactic C-system from a term monad. In this work, we construct an equivalence between the category of C-systems and the category of B-systems, thus proving a conjecture by Voevodsky.

Even if the “value-free ideal of science” (VFI) were an unattainable goal, one could ask: can it be a useful fiction, one that is beneficial for the research community and society? This question is particularly crucial for scholars and institutions concerned with research integrity (RI), as one cannot offer normative guidance to researchers without making some assumptions about what ideal scientific research looks like. Despite the insofar little interaction between scholars studying RI and those working on values in science, the (...) overlap of topics and interests make collaboration between the two fields promising for understanding research and its ethics. Here, we identify—for the use of RI scholars—the non-epistemic reasons (societal, political, professional) for and against the VFI considered in the literature. All of these are concerned with the beneficial or detrimental consequences that endorsing the VFI would have on society, policy-making, or the scientific community, with some authors appealing to the same principles to argue for opposite positions. Though most of the reviewed articles do not endorse the VFI, it is generally agreed that some constraints have to be put on the use of non-epistemic values. Disagreement on the utility of the VFI lies both on the different epistemic-descriptive positions taken by different authors, and on the scarcity of relevant empirical studies. Engaging critically with the reasons here identified and more in general with the values in science debate will help the RI community decide whether the VFI should be included in future codes of conduct.

Les positions philosophiques d'Anthony Collins étaient audacieuses et novatrices, de son rejet de l'idée d'un Dieu doué d'intelligence et de volonté à celui de l'existence d'une âme immatérielle, en passant par sa conception déterministe de la nature et sa vision de l'homme comme machine proche de l'animal, et mue par des pulsions tout aussi hédonistes.

While the debate on values in science focuses on normative questions on the level of the individual (e.g. should researchers try to make their work as value free as possible?), comparatively little attention has been paid to the institutional and professional norms that researchers are expected to follow. To address this knowledge gap, we conduct a content analysis of leading national codes of conduct for research integrity of European countries, and structure our analysis around the question: do these documents allow (...) for researchers to be influenced by “non-epistemic” (moral, cultural, commercial, political, etc.) values or do they prohibit such influence in compliance with the value-free ideal (VFI) of science? Our results return a complex picture. On the one hand, codes of conduct consider many non-epistemic values to be a legitimate influence on the decision-making of researchers. On the other, most of these documents include what we call _VFI-like positions_: passages claiming that researchers should be free and independent from any external influence. This shows that while many research integrity documents do not fully endorse the VFI, they do not reject it and continue to be implicitly influenced by it. This results in internal tensions and underdetermined guidance on non-epistemic values that may limit some of the uses of research integrity codes, especially for purposes of ethical self-regulation. While codes of conduct cannot be expected to decide how researchers should act in every instance, we do suggest that they acknowledge the challenges of how to integrate non-epistemic values in research in a more explicit fashion.

In this paper, I give an analysis of neg-raising inferences as scalar implicatures. The main motivation for this account as opposed to a presupposition-based approach like Gajewski (Linguist Philos 30(3):289–328, 2007) comes from the differences between presuppositions and neg-raising inferences. In response to this issue, Gajewski (2007) argues that neg-raising predicates are soft presuppositional triggers and adopts the account of how their presuppositions arise by Abusch (J Semantics 27(1):1–44, 2010). However, I argue that there is a difference between soft triggers (...) and neg-raising predicates in their behavior in embeddings; a difference that is straightforwardly accounted for in the present approach. Furthermore, by adopting Abusch’s (2010) account of soft triggers, Gajewski (2007) inherits the assumptions of a pragmatic principle of disjunctive closure and of a non-standard interaction between semantics and pragmatics—assumptions that are not needed by the present proposal, which is just based on a regular theory of scalar implicatures. I also show that the arguments that Gajewski (2007) presents in favor of the presuppositional account can be explained also by the scalar implicatures-based approach proposed here. Finally, while the main point of the paper is a comparison with the presuppositional account, I sketch a preliminary comparison with more syntactic approaches to neg-raising. (shrink)

In the last few years, a remarkable convergence of interests and results has emerged between scholars interested in the arts and aesthetics from a variety of perspectives and cognitive scientists studying the mind and brain within the predictive processing (PP) framework. This convergence has so far proven fruitful for both sides: while PP is increasingly adopted as a framework for understanding aesthetic phenomena, the arts and aesthetics, examined under the lens of PP, are starting to be seen as important windows (...) into our mental functioning. The result is a vast and fast-growing research programme that promises to deliver important insights into our aesthetic encounters as well as a wide range of psychological phenomena of general interest. Here, we present this developing research programme, describing its grounds and highlighting its prospects. We start by clarifying how the study of the arts and aesthetics encounters the PP picture of mental functioning (§1). We then go on to outline the prospects of this encounter for the fields involved: philosophy and history of art (§2), psychology of aesthetics and neuroaesthetics (§3) and psychology and neuroscience more generally (§4). The upshot is an ambitious but well-defined framework within which aesthetics and cognitive science can partner up to illuminate crucial aspects of the human mind. -/- This article is part of the theme issue ‘Art, aesthetics and predictive processing: theoretical and empirical perspectives’. -/- .

In this article, I contrast two of the main schools of thought within eco-Marxism, namely Metabolic Rift (MR) and World-Ecology (WE). These differ above all else in their accounts of the ontological status of society and nature. The Covid-19 pandemic constitutes a moment of concretisation of this long-standing debate, which is able to dissolve at least in part its issues. The article consists of four parts. I begin with a summary of the two schools of thought and their core stances, (...) before proceeding to unpack their respective theoretical points of contention. I subsequently proceed to explore the conceptualisation of health according to the Marxist scientists Richard Levins and Richard Lewontin through the model of dialectical biology. In the third section, I unpack the conceptualisation of the Covid-19 pandemic by the epidemiologist Robert Wallace, before finally concluding with the contrasts of the two schools in the light of dialectical biology.

Institutions represent a solid basis to organize and stabilize human life in diferent social contexts. They are external events in the world, but they also have a strong anchorage in the mind and in last years many scholars tried to explore their cognitive ground. Starting from the original attempt of Douglass C. North, who at the end of his career tried to establish a program called “Cognitive Institutionalism”, we discuss the merits and the limits of this approach. First, we show (...) that his statements are cognitively onerous as they imply the notions of mental models and beliefs. Instead, we argue that shared institutions do not require such a convergence and that coordination takes place in the form of social practices and habits. Second, we clarify some aspects of North’s cognitive theory avoiding the ontological reading, i.e. explaining in what sense institutions might depend on the human mind and how people are joined into a practice made possible via institutions.

We propose to develop the problems of selfness, of the tension between the other and the same, and of the singularity, by questioning the philosophies of Kant, Levinas and Stirner, and by reading them trough the theoretical eyes of Jacques Derrida. We will reflect on the irreducibility of the Levinasian other, trying to find out how, to what extent and with what difficulties, the emphasis on singularity can open a dialogical field between, on the one hand, the demand for ethical (...) transcendence required by the encounter with the other, and, on the other hand, the unconditional nature of the moral law in Kantian practical philosophy. After having underlined the limits of the latter, we will compare the non-conceptual and un-graspable character of the other with the radical Stirnerian uniqueness and his need to open the way to what escapes any logocentric chain. The relation between language, singularity and encounter will follow a resumption of Levinasian alterity under a more critical perspective. (shrink)

This work investigates one of the most widespread yet elusive ideas about our experience of art: the idea that there is something cognitively valuable in engaging with great artworks, or, in other words, that we learn from them. This claim and the age-old controversy that surrounds it are reconsidered in light of the psychological and neuroscientific literature on learning, in one of the first systematic efforts to bridge the gap between philosophical and scientific inquiries on the topic. The work has (...) five chapters. Chapter 1 lays down its conceptual bases: it explains what learning is taken to be in the current philosophical debate and it points out how Bayesian cognitive science (particularly in its predictive processing formulations) might be well-suited to capture the kind of learning involved in our engagement with the arts. The following chapters test this latter hypothesis with respect to particular art forms, namely literature and literary language (Chapter 2), narrative (Chapter 3), and visual art, music and motor activities (Chapter 4). The fine-grained discussions conducted in each of these areas will enable us to see that the relationship between art and learning is indeed fundamental and pervasive. The final chapter (Chapter 5) examines the consequences of this fact for our understanding of the role of art in our epistemic practices, its ultimate usefulness and value, and its place in the interdisciplinary study of the human mind. The upshot is a novel and wide-ranging picture, both philosophically informed and empirically sound, that bypasses many of the problems and dead ends of the current philosophical debate on the topic and captures the deep sense in which art and learning are interrelated.

Cellular automata (henceforth: CA) are discrete, abstract computational systems that have proved useful both as general models of complexity and as more specific representations of non-linear dynamics in a variety of scientific fields. Firstly, CA are (typically) spatially and temporally discrete: they are composed of a finite or denumerable set of homogeneous, simple units, the atoms or cells. At each time unit, the cells instantiate one of a finite set of states. They evolve in parallel at discrete time steps, following (...) state update functions or dynamical transition rules: the update of a cell state obtains by taking into account the states of cells in its local neighborhood (there are, therefore, no actions at a distance). Secondly, CA are abstract, as they can be specified in purely mathematical terms and implemented in physical structures. Thirdly, CA are computational systems: they can compute functions and solve algorithmic problems. Despite functioning in a different way from traditional, Turing machine-like devices, CA with suitable rules can emulate a universal Turing machine, and therefore compute, given Turing's Thesis, anything computable....

Institutionalism gives priority to structure over agency. Yet institutions have never developed and operated without the intervention of interested groups. This paper develops a conceptual framework for the role of agency in historical institutionalism. Based on recent contributions following the coalitional turn and drawing on insights from sociological institutionalism, it argues that agency plays a key role in the creation and maintenance of social coalitions that stabilize but also challenge institutions. Without such agency, no coalition can be created, maintained, or (...) changed. Similarly, without a supporting coalition, no contested institution can survive. Yet, due to collective action problems, such coalitional work is challenging. This coalitional perspective offers a robust role for agency in historical institutionalism, but it also explains why institutions remain stable despite agency. In addition, this paper forwards several portable propositions that allow for the identification of who is likely to develop agency and what these actors do. (shrink)

Merleau-Ponty’s later philosophy seems devoted to a fundamental task, knowing how to grasp what he calls a “mutation within the relations of man and Being.” Such a mutation concerns, in the first instance, Merleau-Ponty’s time, knowing the era in which he lives and writes: it is a mutation that is given in history, and thus generated by historical events. At the same time, this mutation has to do with the very essence of time, as the ontological counterpart of being itself. (...) It is, in this later instance, a mutation of the temporality of being: of an intimate being, the being of self, of the unconscious; but also of a communal and shared being—assumed universal—the being of history.An oblique reflection on a temporality thus conceived emerges in his course notes, “Institution in Personal and Public History.” Temporality, here considered as the transcendental of institution, the condition of its possibility, reveals itself as antichronological and anti-metaphysical: it escapes the linearity of successive presents, the retrograde movement of the real, the dialectical movement of history according to Hegel.Indirectly, Merleau-Ponty develops a complex temporal figure—from the structural point of view—where “the past […] takes on the outline of a preparation or premeditation of a present that exceeds it in meaning although it recognizes itself in it.” The past is thus not a former present, but—as mythical past—it is simultaneously in the present itself.This revolution of the temporality of being also affects our time. From the ontological discontinuity emphasized by Merleau-Ponty, the mutation within the relations of man and being happening today seems to be characterized by the loss of all dimensions of time: there is only a present, which, nevertheless, is never present. This is true first of all from a personal point of view: desire no longer pursues its fulfillment—although imaginary and impossible—in the mythical horizon of the past, but rather looks for enjoyment, just as impossible and imaginary, in an elusive present that always exceeds us. This desertification of time also reveals itself in history, where, with and after the postmodern, the present seems to stand out as the only possible temporal dimension, depriving history of its sense and its universality.It seems to us that the philosophy of the later Merleau-Ponty prefigures, or, at least, allows us to think, this subsequent mutation. This is a minor figure, but the subject of significant studies, such as that of “precession,” that can help us not only to understand, but also to re-signify, this mythical present and never present that haunts our time.

Qual è lo statuto libidico dello schermo? In che modo gli schermi coinvolgono le pulsioni dello spettatore, facendo appello alla sua percezione e ai suoi desideri? Nel suo Acinema, Lyotard risponde a tali questioni, affermando che lo schermo cinematografico articola due operazioni opposte. La prima, seguendo un modello rappresentativo, trasforma lo schermo in uno specchio ortopedico – come quello descritto da Jacques Lacan – così producendo il riconoscimento del soggetto nell’immagine proiettata sullo schermo e un conseguente piacere illusorio. La seconda, (...) seguendo invece un principio anti-rappresentativo o de-rappresentativo, impedisce alle pulsioni sparse di riunirsi nell’immagine organica di un soggetto, mostrando così lo schermo stesso, come compimento del desiderio di essere delusi. Lo schermo e lo specchio risultano dunque come opposti in questa relazione dialettica? Come tenterò di mostrare in questo articolo, attraverso la riflessione di Lacan e di Merleau-Ponty, il rapporto tra schermo e specchio può essere concepito a partire dalla figura dell’intreccio ovvero del chiasma.

Il contributo mira a presentare metodi e risultati del progetto di restauro virtuale di un settore dell’antica Porto Torres/Turris Libisonis (Terme centrali, via adiacente e botteghe prospicienti - cd. palazzo del Re Barbaro), frutto di un accordo di collaborazione tra la Direzione Regionale Musei Sardegna e l’Università degli Studi di Padova. Il metodo applicato si basa su tecnologie di fruizione in Realtà Virtuale e ha permesso il restauro virtuale, geolocalizzando il modello virtuale 3D on-site: una App comanda la visualizzazione di (...) immagini equirettangolari all’interno di visori VR, permettendo visite guidate “aumentate”. Il lavoro è partito da una raccolta bibliografica ragionata, alla quale è seguita una campagna di rilievo fotogrammetrico da drone (G. Alvito, Teravista); infine, intrecciando i dati raccolti, si è proceduto alla ricostruzione 3D virtuale degli edifici. Le evidenze strutturali oggi conservate sono state integrate nella scena 3D con puntuali confronti coevi (III sec. d.C.), virtualmente ricostruiti e ricollocati in contesti d’uso verosimili, accrescendo così l’affidabilità ricostruttiva. L’intera attività ricostruttiva è stata vincolata a un rigoroso processo di validazione scientifica basato sul metodo dell’Extended matrix e l’esito finale è ora fruibile sia mediante proiezioni tradizionali (off-site, tourismA 2020), sia mediante l’utilizzo di dispositivi mobili VR (on-site, Giornate europee del patrimonio 2020). In queste e altre occasioni si è riscontrata una eccellente risposta del pubblico, agevolato dal virtuale nella percezione e nella comprensione delle evidenze e delle volumetrie antiche. (shrink)

Bermúdez identifies the “Interface Problem” as the central problem in the philosophy of psychology: how commonsensical psychological explanations can be integrated with lower-level explanations? In particular, since folk psychology is meant to provide causal explanations on a par with, say, neurobiological explanations, the question of how to understand the relation between the two layers arises naturally. Donald Davidson claimed that the interface problem is actually ill-posed and put forward his version of the “Autonomy Picture”, the view known as anomalous monism. (...) This work reviews Davidson’s proposal in the light of digital universes: we model the key claims of the theory using cellular automata and show that Davidson’s original version of the Autonomy Picture is immune to two arguments against autonomy.

This essay takes into account the pedagogical reform for the poor proposed in England by Andrew Bell, Joseph Lancaster and Patrick Colquhoun between Eighteenth and Nineteenth century. Differentiating individuals and reproducing social order through the implementation of a pedagogical plan is a response both to the excessive expectations of well-being raised among the English poor by the Revolution in France, and to the uncontrolled spread of crime and undisciplined behaviours in the new manufacturing districts. This is why social reformers looked (...) at the pedagogical reform of mutual instruction as a way to build the conditions of reproduction of social differences: the plans proposed by Bell and Lancaster, based on emulation, competition and merit, are supported by Colquhoun because they offer a possible solution for the problems of crime and immoral behaviour. «The order of Merit», triggered by emulation, distinction and reward, thus become the main tool of influencing poor’s expectations so to predict and discipline their conduct as future waged workers.

This contribution analyses the scientific and political meaning of the concept of ‘population’ within Thomas Robert Malthus’ thought. It is here argued that by encapsulating ‘population’ in a scientific principle, the author not only aimed at contrasting radical and revolutionary theories of his time; he was also looking for a renovation of the role principles hold in scientific reasoning. He considered this crucial for delineating a plausible science for such an elusive political object as society. Through an examination of key (...) passages of Malthus’ theoretical production – his critique of previous definitions of ‘population’, his reassessment of the natural history of society, and the use of selected metaphors to explain his political thought – it is possible to observe how the author attempted to naturalize society and the inequalities arising from its historical laws. As shown in the conclusions, Malthus’ scientific and political effort was directed towards questioning possibilities to reduce the history of social relations to a path of rational progress, which is consistent with the way he re-conceptualized ‘population’ as regarding the fate of the people and their chances to transform the future in the plausible outcome of their political action in the present.

Why is there a long-standing debate about paraphrase in poetry? Everyone agrees that paraphrase can be useful; everyone agrees that paraphrase is no substitute for the poem itself. What is there to disagree about? Perhaps this: whether paraphrase can specify everything that counts as a contribution to the meaning of a poem. There are, we say, two ways to take the question; on one way of taking it, the answer is that paraphrase cannot. Does this entail that there is meaning (...) mysteriously locked in a poem, meaning that cannot be represented in any way other than via the poem itself? If that were so it would have profound implications for poetry’s capacity to convey insight. We suggest reasons for thinking that the entailment does not hold. Throughout, we connect the traditional debate over paraphrase, which has largely been conducted within the fields of philosophy and literary theory, with recent empirically oriented thinking about the communicability of meaning, represented by work in pragmatics. We end with a suggestion about what is to count as belonging to meaning, and what as merely among the things that determine meaning. (shrink)

Ce qu’on désigne du nom de « complotisme » mérite d’être considéré comme un symptôme – un symptôme de dynamiques et de désirs profondément ambivalents – bien davantage que comme un ennemi « inédit ». L’anti-conspirationnisme nous semble aussi dangereux et ridicule que ce qu’il dénonce sous la catégorie de « complotistes ». Comment nourrir les conspirations émancipatrices qui se tissent dans l’ombre sans se laisser aveugler par des fantasmes de complot embrasés par les élites réactionnaires et certaines viralités toxiques?

This article analyzes business and union strategies in the reform of job security regulations. It argues that unions are the main political actors pushing for their expansion of regulations, but given employers’ opposition, unions are able to enforce better protection only in exceptional periods. Once the first restrictions are in place, employers use their power advantages at the workplace level to circumvent regulations, which unions combat by reducing the level of discretion awarded to employers in interpreting regulations. In recent decades, (...) job security regulations have come under increasing pressure. Unions have reacted to this new situation by consenting to the continuous deregulation of temporary employment, while they fight any attempt at deregulating job security in open-ended contracts in order to protect their members’ interests and their institutional involvement in the administration of dismissals. The theoretical argument is supported by empirical evidence from four Western European countries since the postwar period. (shrink)

This special issue is devoted to trust, institutions, and their ties, specifically. Such ties have been of central concern for philosophers and social scientists for a while, and seem to become an increasingly widespread subject of public debate. This bundle covers two distinct worries, resulting in two (generally complementary) directions of investigation. The classic one, inherited from Hobbes, deals with the importance of institutions for trust. The other one, which is more central to this...

For many years women tended to vote more conservative than men, but since the 1980s this gap has shifted direction: women in many countries are more likely than men to support left parties. The literature largely agrees on a set of political-economic factors explaining the change in women’s political orientation. In this article we demonstrate that these conventional factors fall short in explaining the gender vote gap. We highlight the importance of a religious cleavage in the party system across Western (...) European countries, restricting the free flow of religious voters between left and right parties. Given that surveys show us a constantly higher degree of religiosity among women and a persistent impact of religion on vote choice, religion explains a substantial part of the temporal as well as cross-country variation in the transition from the more conservative to the more progressive voting behavior of women.
