O presente artigo deseja evidenciar que, ainda que a libido e a sexualidade tenham sido incluídas no conceito de Eros a partir de Além do princípio do prazer, a sexualidade no interior no pensamento freudiana não perdeu seu caráter disruptivo e não deixou de ser considerada como causa de profundas perturbações para a vida psíquica humana. Para tal, serão reconstruídos os argumentos sobre a natureza conservadora das pulsões e se procurará propor a ideia de que os conceitos de expansão, repetição (...) e conservação, intimamente associados à dinâmica pulsional, não podem ser vistos como elementos que teriam retirado à sexualidade sua natureza disruptiva e conflitiva no interior da obra freudiana.

O presente artigo deseja evidenciar a interpretação freudiana do drama trágico através dos conceitos e estratégias próprias à psicanálise. Ao evidenciar este movimento interpretativo, oferecemos algumas indicações conceituais sobre o que seria uma estética freudiana: seu modo de proceder, de analisar, de interpretar objetos artísticos. Para tal, traçamos brevemente algumas linhas diretrizes da poética aristotélica e evidenciamos a peculiaridade da análise de Freud sobre o drama trágico.

This article explores the social representation of Information Technology and Network Society from Barthes' semiology, using his ideas about myth creation and the connotation of ideological discourses through naturalization. Supplemented with some concepts from Peirce and Santaella, we try to identify and understand these mystification mechanisms and how they affect the creation of an information order; in this case, a digital order. We conclude that we are before an evangelizing discursive alignment based on mythical elements arisen from our aversion to (...) uncertainty, the energy-saving principle, and an engineering discourse guided by the urgency of profit and power. We highlight the presence of a reckless narrative that permanently repeats the urgent need for information technology and digitalization without considering side effects or costs. (shrink)

We present a new puzzle about logical truth, necessity, and moral responsibility. We defend one solution to the puzzle. A corollary of our preferred solution is that prominent arguments for the incompatibility of determinism and moral responsibility are invalid.

In this paper I critically evaluate the value neutrality thesis regarding technology, and find it wanting. I then introduce the various ways in which artifacts can come to influence moral value, and our evaluation of moral situations and actions. Here, following van de Poel and Kroes, I introduce the idea of value sensitive design. Specifically, I show how by virtue of their designed properties, artifacts may come to embody values. Such accounts, however, have several shortcomings. In agreement with Michael Klenk, (...) I raise epistemic and metaphysical issues with respect to designed properties embodying value. The concept of an affordance, borrowed from ecological psychology, provides a more philosophically fruitful grounding to the potential way(s) in which artifacts might embody values. This is due to the way in which it incorporates key insights from perception more generally, and how we go about determining possibilities for action in our environment specifically. The affordance account as it is presented by Klenk, however, is insufficient. I therefore argue that we understand affordances based on whether they are meaningful, and, secondly, that we grade them based on their force. (shrink)

Causal modelling provides a powerful set of tools for identifying causal structure from observed correlations. It is well known that such techniques fail for quantum systems, unless one introduces 'spooky' hidden mechanisms. Whether one can produce a genuinely quantum framework in order to discover causal structure remains an open question. Here we introduce a new framework for quantum causal modelling that allows for the discovery of causal structure. We define quantum analogues for core features of classical causal modelling techniques, including (...) the causal Markov condition and faithfulness. Based on the process matrix formalism, this framework naturally extends to generalised structures with indefinite causal order. (shrink)

Popular sovereignty requires that citizens perceive themselves as being able to act and implement decisions, and that they are de facto causally connected to mechanisms of decision making. I argue that the two most common understandings of the exercise of popular sovereignty—which center on direct decision making by the people as a whole and the indirect exercise of democratic agency by elected representatives, respectively—are inadequate in this respect, and go on to suggest a complementary account that stresses the central role (...) of internally democratic and participatory political parties in actualising popular sovereignty, drawing on the democratic theory of Hans Kelsen.

Several theists, including Linda Zagzebski, have claimed that theism is somehow committed to nonvacuism about counterpossibles. Even though Zagzebski herself has rejected vacuism, she has offered an argument in favour of it, which Edward Wierenga has defended as providing strong support for vacuism that is independent of the orthodox semantics for counterfactuals, mainly developed by David Lewis and Robert Stalnaker. In this paper I show that argument to be sound only relative to the orthodox semantics, which entails vacuism, and give (...) an example of a semantics for counterfactuals countenancing impossible worlds for which it fails.

Many modern digital products use Machine Learning (ML) to emulate human abilities, knowledge, and intellect. In order to achieve this goal, ML systems need the greatest possible quantity of training data to allow the Artificial Intelligence (AI) model to develop an understanding of “what it means to be human”. We propose that the processes by which companies collect this data are problematic, because they entail extractive practices that resemble labour exploitation. The article presents four case studies in which unwitting individuals (...) contribute their humanness to develop AI training sets. By employing a post-Marxian framework, we then analyse the characteristic of these individuals and describe the elements of the capture-machine. Then, by describing and characterising the types of applications that are problematic, we set a foundation for defining and justifying interventions to address this form of labour exploitation.

We are used to regarding actions and other events, such as Brutus’ stabbing of Caesar or the sinking of the Titanic, as occupying intervals of some underlying linearly ordered temporal dimension. This attitude is so natural and compelling that one is tempted to disregard the obvious difference between time periods and actual happenings in favor of the former: events become mere “intervals cum description”.1 On the other hand, in ordinary circumstances the point of talking about time is to talk about (...) what actually happens or might happen at some time or another. We talk about ‘now’ and ‘then’ in an effort to put some order in our description of what goes on. And since different events seem to overlap in so many different ways, a full account of their temporal relations seems to run afoul of a reductionist strategy. This raises two philosophical questions. The first is whether we can actually go beyond time, as it were, i.e., whether we can take events as bona fide entities and deal with them directly, just as we can deal with spatial entities such as physical bodies or masses without confining ourselves to their spatial representations. This is a controversial issue (though probably not as controversial as it used to be), and ties in with a number of unsettled problems concerning, e.g., the structure of causality or the definition of adequate identity and individuation criteria for events. 2 The second question is whether we can perhaps do without time, i.e., whether we can dispense with time points or intervals as an independent ontological category and focus only on actual or potential happenings, in opposition to the form of reductionism mentioned above—in short, whether we can account for the temporal dimension in terms of suitable relations among events. This is also a highly controversial issue, and relates to the classical dispute concerning relational vs. absolutist conceptions of (space and) time.3 It is this second question that we intend to focus on here..

In this paper I provide an exposition and critique of Johnson and Noorman’s (2014) three conceptualizations of the agential roles artificial systems can play. I argue that two of these conceptions are unproblematic: that of causally efficacious agency and “acting for” or surrogate agency. Their third conception, that of “autonomous agency,” however, is one I have reservations about. The authors point out that there are two ways in which the term “autonomy” can be used: there is, firstly, the engineering sense (...) of the term, which simply refers to the ability of some system to act independently of substantive human control. Secondly, there is the moral sense of the term, which has traditionally grounded many notions of human mor-al responsibility. I argue that the continued usage of “autonomy” in discussions of artificial agency complicates matters unnecessarily. This occurs in two ways: firstly, the condition of autonomy, even in its engineering sense, fails to accurately describe the way “autonomous” systems are developed in practice. Secondly, the continued usage of autonomy in the moral sense introduces unnecessary meta-physical baggage form the free will debate into discussions about moral agency. In order to understand the debate surrounding autonomy, we would therefore first need to settle many seemingly intractable metaphysical questions regarding the existence of free will in human beings.

The 21st century is characterized by an unpredictable and challenging work environment, and the Intrapreneurial Self-Capital (ISC) career and life construct can be seen as a core of individual intrapreneurial resources that enables people to cope with ongoing challenges, changes, and transitions founding innovative solutions when confronted with the constraints imposed by such an environment. The ISC is a challenging construct since it can enhance behavior and attitudes through specific training, unlike personality traits, which are considered substantially stable in the (...) literature. Against this background, the present study examined the relationship between ISC and well-being (hedonic well-being and eudaimonic well-being) controlling for the effects of personality traits. The Big Five Questionnaire (BFQ), the Intrapreneurial Self-Capital Scale (ISCS), the Satisfaction With Life Scale (SWLS), and the Flourishing Scale (FS) were administered to 258 Italian workers. Hierarchical regression analyses showed that ISC explained a percentage of incremental variance beyond that explained by personality traits in relation to both life satisfaction and flourishing. These results indicate that ISC is a key resource for hedonic well-being and eudaimonic well-being and that it offers new research and intervention opportunities. (shrink)

Purpose This study aims to explore whether face recognition technology – as it is intensely used by state and local police departments and law enforcement agencies – is racism free or, on the contrary, is affected by racial biases and/or racist prejudices, thus reinforcing overall racial discrimination. Design/methodology/approach The study investigates the causal pathways through which face recognition technology may reinforce the racial disproportion in enforcement; it also inquires whether it further discriminates black people by making them experience more racial (...) discrimination and self-identify more decisively as black – two conditions that are shown to be harmful in various respects. Findings This study shows that face recognition technology, as it is produced, implemented and used in Western societies, reinforces existing racial disparities in stop, investigation, arrest and incarceration rates because of racist prejudices and even contributes to strengthen the unhealthy effects of racism on historically disadvantaged racial groups, like black people. Practical implications The findings hope to make law enforcement agencies and software companies aware that they must take adequate action against the racially discriminative effects of the use of face recognition technology. Social implications This study highlights that no implementation of an allegedly racism-free biometric technology is safe from the risk of racially discriminating, simply because each implementation leans against our society, which is affected by racism in many persisting ways. Originality/value While the ethical survey of biometric technologies is traditionally framed in the discourse of universal rights, this study explores an issue that has not been deeply scrutinized so far, that is, how face recognition technology differently affects distinct racial groups and how it contributes to racial discrimination.

Focused on city-scale automation, and using self-driving cars (SDCs) as a case study, this article reflects on the role of AI—and in particular, computer vision systems used for mapping and navigation—as a catalyst for urban transformation. Urban research commonly presents AI and cities as having a one-way cause-and-effect relationship, giving undue weight to AI’s impact on cities and overlooking the role of cities in shaping AI. Working at the intersection of data science and social research, this paper aims to counter (...) this trend by exploring the reverse perspective: how do cities affect the development, and expose the present limits, of SDCs? The contribution of this paper is threefold. First, by comparing urban and nonurban environments and thoroughly examining the relationship between computer vision and city-specific sociality and form, it defines machine autonomy/automation as a function of the sociotechnical milieu in which an AI system operates. Second, and related, the paper problematizes the notion of SDCs as autonomous technologies and the role it plays in envisioning contending policy arrangements and technical solutions for achieving full driving automation. Finally, the article offers insight into a materialist and spatialized understanding of AI—namely, not as an abstract quality susceptible to replication within discrete machines, but rather as a distributed property emerging through embodied interactions among a multiplicity of agents (human, non-human, and technological) within/with their environments.

The semantic view of theories is normally considered to be an ac-count of theories congenial to Scientific Realism. Recently, it has been argued that Ontic Structural Realism could be fruitfully applied, in combination with the semantic view, to some of the philosophical issues peculiarly related to bi-ology. Given the central role that models have in the semantic view, and the relevance that mathematics has in the definition of the concept of model, the fo-cus will be on population genetics, which is (...) one of the most mathematized areas in biology. We will analyse some of the difficulties which arise when trying to use Ontic Structural Realism to account for evolutionary biology. (shrink)

In this paper, I argue that the temporal connective prima (‘before’) is a comparative adverb. The argument is based on a number of grammatical facts from Italian, showing that there is an asymmetry between prima and dopo (‘after’). On the ground of their divergent behaviour, I suggest that dopo has a different grammatical status from prima. I propose a semantic treatment for prima that is based on an independently motivated analysis of comparatives which can be traced back to Seuren (in: (...) Kiefer and Ruwet (eds.) Generative grammar in Europe, 1973). Dopo is analyzed instead as an atomic two-place predicate which contributes a binary relation over events to the sentence meaning. The different semantic treatments of the two connectives provide an explanation for the grammatical asymmetries considered at the outset; interestingly, they also shed some light on other asymmetries between prima and dopo, which are known to hold for the English temporal connectives before and after as well: these asymmetries are related to the veridicality properties, the distribution of NPIs, and the logical properties of these connectives first described in Anscombe (Philos Rev 73:3–24, 1964).

This chapter tries to answer the following question: How should we conceive of the method of mathematics, if we take a naturalist stance? The problem arises since mathematical knowledge is regarded as the paradigm of certain knowledge, because mathematics is based on the axiomatic method. Moreover, natural science is deeply mathematized, and science is crucial for any naturalist perspective. But mathematics seems to provide a counterexample both to methodological and ontological naturalism. To face this problem, some authors tried to naturalize (...) mathematics by relying on evolutionism. But several difficulties arise when we try to do this. This chapter suggests that, in order to naturalize mathematics, it is better to take the method of mathematics to be the analytic method, rather than the axiomatic method, and thus conceive of mathematical knowledge as plausible knowledge.

There are three main accounts of scientific progress: 1) the epistemic account, according to which an episode in science constitutes progress when there is an increase in knowledge; 2) the semantic account, according to which progress is made when the number of truths increases; 3) the problem-solving account, according to which progress is made when the number of problems that we are able to solve increases. Each of these accounts has received several criticisms in the last decades. Nevertheless, some authors (...) think that the epistemic account is to be preferred if one takes a realist stance. Recently, Dellsén proposed the noetic account, according to which an episode in science constitutes progress when scientists achieve increased understanding of a phenomenon. Dellsén claims that the noetic account is a more adequate realist account of scientific progress than the epistemic account. This paper aims precisely at assessing whether the noetic account is a more adequate realist account of progress than the epistemic account. (shrink)

This paper analyzes the impact that Lamarckian evolutionary theory had in the scientific community during the period between the advent of Zoological Philosophy and the publication Origin of Species. During these 50 years Lamarck’s model was a well known theory and it was discussed by the scientific community as a hypothesis to explain the changing nature of the fossil record throughout the history of Earth. Lamarck’s transmutation theory established the foundation of an evolutionary model introducing a new way to research (...) in nature. Darwin’s selectionist theory was proposed in 1859 to explain the origin of species within this epistemological process. In this context, Charles Lyell’s Principles of Geology and Auguste Comte’s Cours de Philosophie Positive appear as two major works for the dissemination of Lamarck’s evolutionary ideology after the death of the French naturalist in 1829.

ABSTRACT Quaderni piacentini, set up in 1962 by Piergiorgio Bellocchio and Grazia Cherchi, was probably the most iconic leftist periodical in Italy before 1968. Its criticism against both the Italian Communist Party for its non-revolutionary policy and the reformist centre-left coalition, its uncompromising ethics, and its exploring into non-orthodox Marxist approaches made it representative of the intellectual New Left in Italy, against the background of advanced industrialization. This article explores the changing perception of the role of intellectuals in society from (...) classic forms of an elitist political involvement to the desired identification with the masses. It argues that between the two different ways to approach culture that intersected in Quaderni piacentini and characterized the debate around 1968, namely the one expressed by Franco Fortini – advocate of the function of intellectuals and of the use of literature for political purposes – and the one supported by Alberto Asor Rosa – convinced of the need for a self-destruction of traditional ʻbourgeois' disciplines – the periodical tended to side with the former, in order to keep culture a credible and legitimate tool for militancy.

This paper investigates and develops generalizations of two-dimensional modal logics to any finite dimension. These logics are natural extensions of multidimensional systems known from the literature on logics for a priori knowledge. We prove a completeness theorem for propositional n-dimensional modal logics and show them to be decidable by means of a systematic tableau construction.

How should one conceive of the method of mathematics, if one takes a naturalist stance? Mathematical knowledge is regarded as the paradigm of certain knowledge, since mathematics is based on the axiomatic method. Natural science is deeply mathematized, and science is crucial for any naturalist perspective. But mathematics seems to provide a counterexample both to methodological and ontological naturalism. To face this problem, some naturalists try to naturalize mathematics relying on Darwinism. But several difficulties arise when one tries to naturalize (...) in this way the traditional view of mathematics, according to which mathematical knowledge is certain and the method of mathematics is the axiomatic method. This paper suggests that, in order to naturalize mathematics through Darwinism, it is better to take the method of mathematics not to be the axiomatic method. (shrink)

Althusser’s Machiavelli and Us has often been considered as the French Marxist’s first step on the path beyond Marxism. This article opposes this interpretation by showing that, while Machiavelli helps Althusser to renounce any attempt to deduce a communist political practice from the necessity portrayed by a theory of history, Althusser was mindful not to identify the relationship between the communist party and the masses with the relationship between the Prince and the people. From a Marxist perspective, a communist political (...) practice must further the autonomous political initiatives of the masses that delineate a tendency towards the withering-away of the state and cannot merge with a practice of governing the people. This is why Marxism must not forsake its theory of history but employ it in the process of the subtraction of the party to its becoming-state by detecting the conditions of impossibility of the duration of a communist political practice.

No interior do pensamento de Dewey, a gênese da estética merece mais atenção do que lhe é dada na literatura. Um aspecto, em especial, tem sido virtualmente negligenciado — com as notáveis exceções de Robins 2015, Ueno 2016, Hein 2017 e Granger 2018a e 2018b — a saber, os vínculos com Albert Coombs Barnes. Nossa hipótese é que Barnes desempenhou um papel relevante na “virada estética” da filosofia madura de Dewey. Neste artigo, nós tomamos um primeiro passo rumo ao esclarecimento (...) da relação entre eles e uma tentativa de mostrar a influência do colecionador de arte na obra do filósofo. (shrink)

Scientific Realism (SR) has three crucial aspects: 1) the centrality of the concept of truth, 2) the idea that success is a reliable indicator of truth, and 3) the idea that the Inference to the Best Explanation is a reliable inference rule. It will be outlined how some realists try to overcome the difficulties which arise in justifying such crucial aspects relying on an adaptationist view of evolutionism, and why such attempts are inadequate. Finally, we will briefly sketch some of (...) the main difficulties the realist has to face in defending those crucial aspects, and how such difficulties are deeply related: they derive from the inability of SR to satisfyingly avoid the sceptical challenge of the criterion of truth. Indeed, SR seems not to be able to fill the so-called ‘epistemic gap’ (Sankey 2008). In fact, the epistemic gap cannot be filled in no way other than obtaining a criterion of truth, but such a criterion cannot be obtained if the epistemic gap obtains. (shrink)

Le principali concezioni del progresso scientifico sono tre: la concezione epistemica, secondo cui il progresso si verifica quando si verifica un incremento della conoscenza; la concezione semantica, secondo cui il progresso si verifica quando vi è un incremento delle verità; la concezione problem-solving, secondo cui il progresso si verifica quando si verifica un incremento del numero dei problemi che si è in grado di risolvere. La concezione epistemica è ritenuta la più compatibile con una prospettiva realista. Di recente, Dellsén ha (...) proposto la concezione “noetica”, secondo cui il progresso si verifica quando vi è un incremento dell’understanding di un fenomeno da parte degli scienziati. Dellsén sostiene che la concezione noetica sia una concezione realista del progresso più adeguata di quella epistemica. Scopo di questo articolo è valutare se la concezione noetica sia più adeguata della concezione epistemica. (shrink)

Peter D. Thomas’s book The Gramscian Moment: Philosophy, Hegemony and Marxism draws us to reflect on a point that Gramsci’s interpreters have often neglected: the particular structure of the Prison Notebooks, i.e., the ways in which the text was constituted and, dependent on that, the fundamental methodological criteria for its interpretation. Thomas’s book is a consummate synthesis between the deep and detailed study of the Notebooks text and the need to reconstruct some order within; between close historicalphilosophical assessment and theoretical (...) proposal within contemporary Marxist (and para-Marxist) debate. Consequently, this book confronts us – as Gramsci’s present-day readers – with a task that no-one can face alone, but that is nonetheless extraordinarily urgent: the task of intervening in the debate within the post-modern and post-Marxist Left so that the link between Marxism and philosophy is resumed, starting out from Gramsci himself. In short: a revival of Marx through Gramsci, through – in turn – a return of the philosophy of praxis as Marxism for our own day. (shrink)

A laughter that will bury you: the morality of plant-based meat irony When plant-based meats enter the foodscape, they face the challenge of how to communicate their nature and function to consumers: one strategy for navigating the tension between portraying conventional meat as something to be replaced and affirming their unique meaty tastiness is through ironic claims and performances. This paper seeks to analyse the moral stance of irony in plant-based meat advertisements, specifically when this irony involves the death of (...) animals. Firstly, it presents an argument showing that, from the standpoint of veganism, ironising about animals’ death can be a moral wrong. Secondly, by relying on an interpretation of irony that leverages its potential for subverting and criticising hegemonic viewpoints, it is shown that this kind of irony can serve as a form of resistance aimed at dismantling the pervasive indifference towards the killing of animals for producing meat.

Lo scopo di questo saggio consiste nell’individuare un punto di partenza adeguato per lo sviluppo di una teoria filosofica delle etiche applicate, cioè di un discorso che si assuma il compito di comprendere che cosa siano le etiche applicate, quali siano le loro strutture principali, in che cosa consista la loro novità e quale significato esse rivestano nei confronti del pensiero morale. Un approccio organico e unitario a questi temi, tuttavia, non è ancora stato impostato. Per questo motivo si rende (...) innanzitutto necessaria una analisi preliminare volta sia a chiarire la possibilità di una simile indagine, sia ad individuare un punto di partenza da cui muovere. Si propone così per prima cosa una discussione critica dei diversi termini a cui si ricorre per nominare il fenomeno sotto esame (§2, problema terminologico). In seguito si affronta la questione dei rapporti reciproci delle diverse etiche applicate e della relazione che esse intrattengono con la filosofia morale e i saperi in cui si inscrivono (§3, problema architettonico). Infine, si riconducono le controversie ad un problema fondamentale (§4), relativo al tema dell’applicazione e del rapporto di teoria e prassi nell’esperienza morale. L’esperienza di tale problema rappresenta il contenuto unificante delle etiche applicate e, allo stesso tempo, ne rende evidente il carattere propriamente filosofico. Da una sua discussione non solo l'etica applicata può trarre preziose informazioni su di sé, ma la stessa filosofia morale può guadagnare un nuovo accesso ad alcuni dei suoi temi principali.

Between the 1960s and the 1970s, Marxism reached its maximum success in Italy, but that phase also corresponded to the crisis of the Italian Communist Party’s cultural hegemony, challenged by both the attacks coming from the New Left and innovative readings of Marx’s works. Marxist historicism, on which the Italian Communist Party had based its cultural policy after the the Second World War, consequently suffered heavy attacks. This article illuminates one of the responses to historicism’s decline, providing an account of (...) the book series La Scienza Nuova, issued by the publishing house Dedalo in Bari and edited by the communist intellectual Mario Spinella, who was able to remain loyal to his party demonstrating, at the same time, cultural autonomy. Also grounding on archival documents, the article posits that Spinella’s aim was to attract New Left readers by selecting books on topics and by authors that were in fashion in Italy and abroad, but incorporating them into a theoretical framework based on Marxist historicism, in order to preserve the latter in an evolving cultural environment.

An experiment aimed at detecting a DC voltage across a conductor induced by the steady magnetic field of a coil, carried out in 1998, provided a positive (although preliminary) evidence for such an effect, which might be interpreted as a breakdown of local Lorentz invariance. We repeated in 1999 the same experiment with a different experimental apparatus and a sensitivity improved by two orders of magnitude. The results obtained are discussed here in detail. They confirm the findings of the previous (...) experiment, and show, among the others, that the effect is independent of the direction of the current. A possible interpretation of the results is given in terms of a geometric description of the gravitational and the electromagnetic interactions by means of phenomenological, energy-dependent metrics.

This article takes as its point of departure the conviction that late medieval science should be studied in its own right, and not merely to determine whether it presaged developments in early modern science. Case in point: Francis of Marchia's theory of virtus derelicta, the theory that the motion of a projectile through the air is due to a force left behind by the original motive force. Certainly, Marchia's view is not a forerunner of inertia. Nevertheless, it is argued that (...) virtus derelicta breaks with two important Aristotelian principles of motion: "everything that has a beginning must necessarily also have an end" and "form is always indivisible." Thus, virtus derelicta is neither an Aristotelian solution to the problem of projectile motion nor a development on the road to early modern science; it belongs to a new (but subsequently undeveloped) understanding of motion.

Gramsci’s theory of hegemony is currently understood as a theory of power in Western, democratic societies, and therefore as a theory of cultural power (“cultural hegemony”). The aim of this article is to show that this interpretation is erroneous, at least for three reasons. Firstly, because the notion of “democracy” itself has to be placed within its historical context: the meaning of “democracy” in the 1920s and 1930s in Europe was very different from what it became in the post-WWII era. (...) Secondly, because all the regimes Gramsci could have been taking into account when he wrote the Prison Notebooks were the result of the crisis of the Liberal State and parliamentarianism. Even if in different ways, political conflict in each of them unfolded in a manner that is very different from what is today presupposed by the notion of cultural hegemony. And thirdly, because the genetic reconstruction of Gramsci’s concept of hegemony, as it is developed in the Prison Notebooks, will show that the core of what is usually considered the Gramscian theory of hegemony was already developed before 1926 (I shall refer to it as “standard theory”), while in the Notebooks he substantially updated this theory, in order to think the new conditions of political struggle in Italy and Europe. This revision can be summarised in three points. First: the notion of hegemony is organically combined with that of “war of position”. The latter will refer no longer the political struggle characterised by a strongly developed civil society, typical of the “West” (as opposed to backward “Eastern” context). The war of position is now the sort of political struggle that we have when huge masses of population enter into political life and actively participate in it. It thus means not a place where political struggles take place but a phase of these struggles, that Gramsci calls “culminating” and “decisive”. The image Gramsci adopts to visualise this phase of political struggles is that of two “reciprocal sieges”: of the masses to the State and of the State to the masses. Second: “hegemony” comes to mean now the means the rulers adopt with the purpose of winning the support of the masses. Politics is no longer the business of active minorities; it is now the organisation of the lifestyle of huge masses of population, in order to control their political agency (hence the notion of “passive revolution”). Third, from the above, the importance of religion follows since it is the most widespread language, as well as that of political myths which manage to mobilise politically social forces, translating religion into political action and the vice-versa, political ideology into religious faith.

We consider the problem of finding, in the ambit of modal logic, a minimal characterization for finite Kripke frames, i.e., a formula which, given a frame, axiomatizes its theory employing the lowest possible number of variables and implies the other axiomatizations. We show that every finite transitive frame admits a minimal characterization over K4, and that this result can not be extended to K.

We find a short way to construct a formula which axiomatizes a given finite frame of the modal logicK, in the sense that for each finite frameA, we construct a formula A which holds in those and only those frames in which every formula true inA holds.To obtain this result we find, for each finite model and each natural numbern, a formula which holds in those and only those models in which every formula true in , and involving the firstn (...) propositional letters, holds.
