The nature of matter and the idea of indivisible parts has fascinated philosophers, historians, scientists and physicists from antiquity to the present day. This collection covers the richness of its history, starting with how the Ancient Greeks came to assume the existence of atoms and concluding with contemporary metaphysical debates about structure, time and reality. Focusing on important moments in the history of human thought when the debate about atomism was particularly flourishing and transformative for the scientific and philosophical spirit (...) of the time, this collection covers: - The discovery of atomism in ancient philosophy - Ancient non-Western, Arabic and late Medieval thought - The Renaissance, when along with the re-discovery of ancient thought, atomism became once again an important doctrine to be fully debated - Logical atomism in early analytic philosophy, with Russell and Wittgenstein - Atomism in Liberalism and Marxism - Atomism and the philosophy of time - Atomism in contemporary metaphysics - Atomism and the sciences Featuring 28 chapters by leading and younger scholars, this valuable collection reveals the development of one of philosophy's central doctrines across 2,500 years and within a broad range of philosophical traditions.

The paper focuses on the analysis of conspiracy beliefs and conspiracy theories by taking into consideration some of the major contributions about the topic presently provided by several disciplines. A definition is given that helps illustrate the most prominent features of these beliefs, namely monological bias, logical and conceptual fallacies, dispositional influence and pseudorationality. Other important psychological preconditions are also provided (such as, among others, credulity, hypersensitive agency detection devices and proneness to self-deception), but, as the paper argues, they are (...) features shared to a greater or lesser extent with other belief systems, like radical political ideologies and religious fundamentalisms. As a result, it is suggested that a more proper understanding of the phenomenon is attainable by approaches combining psychological data with the analysis of groups and sociopolitical dynamics. Exceptional contingencies and shifts in power distribution among group/social actors seem to be the most influential factors that explain formation, spread and salience of this kind of beliefs.

In the two golden centuries that followed the death of Socrates, ancient philosophy underwent a tremendous transformation that culminated in the philosophical systematizations of Plato, Aristotle and the Hellenistic schools. Fundamental figures other than Plato were active after the death of Socrates; his immediate pupils, the Socratics, took over his legacy and developed it in a variety of ways. This rich philosophical territory has however been left largely underexplored in the scholarship. This collection of eleven previously unpublished essays by leading (...) scholars fills a gap in the literature, providing new insight into the ethics, metaphysics, and epistemology as developed by key figures of the Socratic schools. Analyzing the important contributions that the Socratics and their heirs have offered ancient philosophical thought, as well as the impact these contributions had on philosophy as a discipline, this book will appeal to researchers and scholars of Classical Studies, as well as Philosophy and Ancient History.

This book explores how the design, construction, and use of robotics technology may affect today's legal systems and, more particularly, matters of responsibility and agency in criminal law, contractual obligations, and torts. By distinguishing between the behaviour of robots as tools of human interaction, and robots as proper agents in the legal arena, jurists will have to address a new generation of "hard cases." General disagreement may concern immunity in criminal law (e.g., the employment of robot soldiers in battle), personal (...) accountability for certain robots in contracts (e.g., robo-traders), much as clauses of strict liability and negligence-based responsibility in extra-contractual obligations (e.g., service robots in tort law). Since robots are here to stay, the aim of the law should be to wisely govern our mutual relationships. (shrink)

(English:) This contribution attempts a first non-normative approach to the problem of the classic, its definition and its meaning in an age of globalization. It reviews a series of common representations of the classic (and other analogous or contrary terms), stressing the programmatic-ideological aspect that generally characterizes them. Classic, actually, tends to be a foundational category, and therefore rests on delimitations that determine its exclusiveness as opposed to something else. This paper, in particular, criticizes the last boundary of the exclusivity (...) of the classic, that is, its normative opposition to fashion and actuality. On the contrary, it is argued that there is a substantial link between classic, actuality and fashion. On the basis of this connection, two deflationary definitions of the classic are proposed: the first regards it as part of the broader process of construction of historical identity by concrete individuals. The second, on the other hand, conceives it as a product of art, and, therefore, of a formative process of abilities, skills, taste, by which the classic becomes the object of technical, aesthetic and teleological judgments. -/- (Spanish:) En esta contribución se intenta una primera aproximación no normativa al problema del clásico, su definición y su significado en una era de globalización. Se revisa una serie de representaciones comunes sobre lo clásico (y otros términos análogos o contrarios), se destaca el aspecto programático-ideológico que por lo general las caracteriza. Clásico, en efecto, tiende a ser una categoría fundacional, por lo cual se apoya en delimitaciones que determinan su exclusividad por oposición a otra cosa. En este trabajo, en particular, se critica la última frontera de la exclusividad de lo clásico, es decir, su oposición normativa a la moda y la actualidad. Por el contrario, se argumenta que existe un vínculo sustancial entre el clásico, la actualidad y la moda. A partir de esta conexión, se proponen dos definiciones deflacionarias del clásico: la primera lo considera parte del proceso más amplio de construcción de la identidad histórica por parte de individuos concretos. El segundo, en cambio, lo concibe como un producto del arte, y, por tanto, de un proceso de formación de competencias, habilidades, gusto, por el cual el clásico se convierte en objeto de juicios técnicos, estéticos y teleológicos.

The paper provides both a description of conspiracy beliefs and an insight into their cultural significance. On one side, it highlights their specific formal features, on the other, and this constitutes its peculiarity in the recent literature on the topic, it considers them within the broader genre of general conceptual beliefs, whose main characteristics are weak methodology and logical structure, strong affective and dispositional constraints, epistemic closure and mauvaise foi, and whose main function is practical and self-representative (not epistemic). The (...) paper also claims that political theory and social sciences had some influence in legitimizing certain ideas and stereotypes that are exacerbated in conspiracy beliefs, while other te(le)ological conceptions, such as finalism and providence, may be an important source of ideas that turn out to be widely spread in contemporary criticism towards those same beliefs.

The knowledge of truth, in Plato, is an experience that calls for conversion of the soul (μεταστροφή, περιστροφή). The basic feature of this experience consists in some sort of connection, which is constantly at work, between rational arguments and their non-rational conditions, briefly, lógos and páthos. How does this connection show up in Plato? Its crucial importance emerges many times at both narrative (récit) and theoretical level. In the three parts of my contribution, I show how logos-pathos intertwines with Plato's (...) notion of conversion considered as a double-sided phenomenon, as both "process" of moral education and "noetic event".

L’articolo mira ad indagare le trasformazioni che stanno subendo le istituzioni formative sotto la pressione delle direttive europee secondo modelli aziendali di stampo neoliberale. L’analisi genealogica e il confronto con la documentazione istituzionale europea e nazionale suggeriscono che le riforme scolastiche degli ultimi trent’anni, centrate sulla logica delle competenze e sul modello dell’impresa, siano elaborate per essere un supporto fondamentale alle pratiche di soggettivazione neoliberale. La centralità della nozione di competenza e l’insistenza sulla necessità di sviluppare ed applicare un numero (...) sempre maggiore di strumenti di misurazione dei saperi portano a definire un orizzonte educativo che si pone come scopo principale la formazione di individui utili al sistema produttivo, tanto sul piano delle capacità tecniche quanto sul piano valoriale. Un sistema educativo con questi obiettivi comporta lo snaturamento e la svalutazione di tutta una serie di ambiti del sapere, uno su tutto quello filosofico. La didattica delle competenze sta trasformando lo studio della filosofia da sapere critico a semplice adattamento a quei sistemi di valutazione che rispondono alle logiche del mondo dell’impresa: nella migliore delle ipotesi un insieme di soft skill, nella peggiore una vera e propria ancella della cultura aziendalista.

Ideologies, worldviews, or simply personal theories, often acquire a distorted and pathological character, and become a factor of alienation rather than an epistemic resource and an aid for personal existence. This paper attempts to better define the limits and characteristics of this experience, which we call distorted intellectual beliefs, or general conceptual beliefs (GB), while trying to highlight both its sometimes dramatic background and its personal and social consequences, which are no less potentially deleterious. We believe that such experiences should (...) not be confused tout court with a broader and more complex phenomenon, such as extremism and politico-religious radicalism, but are a specific typology of that broader and multifaceted fact that is self-deception. We hypothesize that the self-deception implicit in experiences of intellectual distortion produces a cognitive dissonance of which the subject is normally, though with varying intensity, aware (or may become aware through honest introspection). The phenomenon occurs in two extreme forms: one is normal (sporadic), the other is exceptional (systematic). The passage from one to the other is a complex process of escalation and de-escalation, on which multiple external and internal variables act. In its ascending path, it essentially coincides with a process of psychological polarization and cognitive "de-pluralization", while its descending phase marks a return to reality and a "re-pluralization", where the subject returns to being what he basically is, namely, an active and tireless meaning seeker. In the central part of the chapter, similarities and differences between processes of deradicalization and phenomena of religious deconversion are analyzed, with reference, among others, to the case of the Austro-Hungarian writer Arthur Koestler. -/- An abridged version of this text has been delivered for the Workshop "Explaining Extreme Belief and Extreme Behavior", September 15-16, 2022, Vrije Universiteit Amsterdam.

The paper examines the open problems that experts of space law shall increasingly address over the next few years, according to four different sets of legal issues. Such differentiation sheds light on what is old and what is new with today’s troubles of space law, e.g., the privatization of space, vis-à-vis the challenges that AI raises in this field. Some AI challenges depend on its unique features, e.g., autonomy and opacity, and how they affect pillars of the law, whether on (...) Earth or in space missions. The paper insists on a further class of legal issues that AI systems raise, however, only in outer space. We shall never overlook the constraints of a hazardous and hostile environment, such as on a mission between Mars and the Moon. The aim of this paper is to illustrate what is still mostly unexplored or in its infancy in this kind of research, namely, the fourfold ways in which the uniqueness of AI and that of outer space impact both ethical and legal standards. Such standards shall provide for thresholds of evaluation according to which courts and legislators evaluate the pros and cons of technology. Our claim is that a new generation of sui generis standards of space law, stricter or more flexible standards for AI systems in outer space, down to the “principle of equality” between human standards and robotic standards, will follow as a result of this twofold uniqueness of AI and of outer space.

We study the decidability problem for metric and layered temporal logics. The logics we consider are suitable to model time granularity in various contexts, and they allow one to build granular temporal models by referring to the "natural scale" in any component of the model and by properly constraining the interactions between differently-grained components. A monadic second-order language combining operators such as temporal contextualization and projection, together with the usual displacement operator of metric temporal logics, is considered, and the theory (...) of finitely-layered metric temporal structures is shown to be decidable.

Cet article s’attache à comprendre si les cyrénaïques étaient susceptibles d’être attaqués moyennant l’objection d’inactivité et, si oui, comment ils auraient pu essayer d’y répondre et quel type de vision morale ils auraient pu essayer de défendre. En traitant de ces questions, j’évaluerai la légitimité de l’interprétation du scepticisme cyrénaïque offerte par Jules Vuillemin. Je confirmerai ainsi la plausibilité de son interprétation et développerai en même temps l’exploration de la nature et de la portée de la philosophie cyrénaïque.

The contribution describes the legal phenomenon as a playing field characterized by a progressive regression of the law, understood as a sovereign will from top to bottom, both in the vision of formalist legal positivisms in continental Europe and in realist terms, in the United States. Soft law represents the main strategy to subordinate the law to the interests of the economy, elasticizing environmental law, making it favorable to the market, reducing ecology to the simplistic metric of CO2 emissions. The (...) consequence is a retreat of the statist vertical normativity of law which is not replaced by a de facto power granted to those who control the technology, built by design to close spaces for pluralism and democratic action, in the interest of surveillance and concentrated power in private and government oligopolies. The author concludes by advocating the urgency for genuinely innovative categories, particularly in the legal education, such as the commons, capable of including sustainability into a “new ecological jurisprudence committed to inclusion and solidarity rather than exclusion and struggle”.

The Μικρομεγάλη Ἰλιάς, the first work written by John Tzetzes, consists of 1.676 hexameters and numerous scholia. It narrates the events of the Trojan war from the conception of Paris to the fall of the city. This paper analyses the poem and its structure. In his later Exegesis to the Iliad, Tzetzes states that the Μικρομεγάλη Ἰλιάς allows to “learn thoroughly, in every detail” the history of the war. Following this evidence, the macro- and the microstructure of the poem are (...) analysed in order to understand how Tzetzes structured his literary work and to what end. The last paragraph deals with the title Μικρομεγάλη Ἰλιάς. (shrink)

Platonic religiosity is the first of two volumes devoted to the analysis of religiosity or religious feeling (pathos) in Plato. -/- (Back cover) Platonic Religiosity is a hermeneutical attempt to read Platonic works from the perspective of their religiosity. The aspects examined in the book are limited for the moment to the most basic, perhaps even the simplest, dimensions of religious feeling, those involving the representation of a relationship between man and divinity, Earth and Heaven, "low" and "high". Low and (...) high are spatial metaphors constitutive of our thinking. Although, in this case, they indicate the link between man and the super-sensible world, they also presuppose, at all times, the devout feeling (and the risk) of an insurmountable distance and remoteness that divides men from the numen. The need to affirm the relationship partly overcomes the presence of this feeling of distance, but never manages to neutralise it completely. -/- Religious feeling as such always oscillates between two terms: the need to establish a relationship with the divinity, and thus to guarantee its proximity to man, and the affirmation of its transcendence, namely the distance that divides us from the numen, up to the point, eventually, where the danger becomes the greatest: the denial of the god by man (atheism) or the human feeling of being abandoned by the god. The presence of these oscillations in the Platonic texts is analysed in several chapters of the book, devoted to different themes, such as the representations of reciprocity (do ut des), the images of the friendly god and the hostile god, the feeling of the threshold, prayers and invocations, verecundia and nostalgia, the feeling of dependence, the notion of prescience, assimilation to the god, the different types of ineffability, the role of atheism and incredulity, and lastly the notion of conversion, which substantiates Platonic religiosity by characterising it in the sense of a redemption-belief.

Ineffability in Plato is a conundrum. There are at least four dimensions of ineffability in Platonic texts: epistemic (divine), strategic (religious), unspeakability and incommunicability. In this paper, I deal only with the first dimension, which is strictly epistemic in kind, and defend that Plato rejects divine ineffability, namely, the belief that the knowledge of the divine in general is inaccessible to the human mind. Several crucial passages attest to this rejection unequivocally. They show that Plato attached a great philosophical relevance (...) to what I call the equivalenceprinciple, namely, the interdependence or specularity between human and divine intelligence. The assertion of this principle represents the Platonic path to absolute knowledge, which I try to locate in the broader context of the history of philosophy, from early philosophers to Hegel.

Ugo Spirito's _Memoirs of the Twentieth Century_ is the intellectual autobiography of one of the most original and anticonformist contemporary Italian philosophers. In it, Spirito makes an evaluation of his long career (spanning from the decade of the 20's to that of the 70's of the twentieth century) as a thinker who was never satisfied with any theoretical or philosophical system, while constantly aiming at finding a definitive truth: the “incontrovertible” or absolute. The various stages of his search deal with (...) different philosophical and scientific systems - from positivism to actual idealism, from problematicism to omnicentrism, from scientism to neoproblematicism - revealing at the same time an inherent antinomic procedure that does not permit him to take any truth for granted. At the end of his life, Spirito realized that he could only be sure of his present state of “unawareness,” thus challenging the validity of his lifelong investigative activity. “Man cannot know himself,” Spirito wrote. Confronted with the manifestations of life and universe, he could not help but feel a sense of “surprise and astonishment.” Throughout his life, he was only a spectator of his destiny, not the conscious creator of it, as he believed in the early stage of his career. Consequently, he reached a position of negating any value system, bordering on skepticism and nihilism. Within this context, he offered a post-modern interpretation of life. This interpretation was also Spirito's conclusion, and as such, implied a rethinking about other faiths, both political and ideological, that for more than fifty years would develop parallel to philosophical faith. Consequently, he revisited some of the most important philosophical and political personalities who interpreted or materialized those faiths, from Benedetto Croce to Gentile, from Benito Mussolini to Giovanni Bottai, from Togliatti to Pope Paul VI. Spirito was not a thinker who remained secluded within the ivory tower of pure investigation, but in an effort to modify society according to principle of the identification of philosophy with life, he tried to act upon it by following thoughts with action. _Memoirs of the Twentieth Century_ is divided in two parts: one purely autobiographical and theoretical, and the other more historical, where Spirito narrates his relationship with the above-mentioned personalities, as a way of testing the validity of his beliefs. Indeed, one can perceive his moment of adherence to each of the different approaches expounded, only to subsequently detach himself from them. For the English-speaking reader, the second part will appear more interesting and poignant, since Spirito's involvement with history foretells the intellectual fate of a nation. _Memoirs of the Twentieth Century_ is a reflection on life, in which personal history serves as a vehicle for judgment upon an entire century.

En 1819, Arthur Schopenhauer fait paraître son grand ouvrage, Le Monde comme volonté et représentation, et s’attend à rencontrer un vif succès. Très vite, ses espoirs se dissipent devant l’indifférence qui entoure la réception de ce qui reste néanmoins à ses yeux un chef-d’œuvre. Il n’hésite pas d’ailleurs à voir derrière ce silence pesant le signe d’une cabale menée par les plus médiocres philosophes, c’est-à-dire ceux qui ne vivent pas, comme lui, pour la philosophie mais de la philosophie....

The Jewish Law (Halakahh) is probably the older legal system working in our time. It is established on a hierarchy of different texts. The oldest and more authoritative is the Torah (the five books of Moshe), then come the Mishnah, the Talmud, the compilation as Maimonide’s Mishne Torah and Caro’s Shulchan Arukh, then the responsa of the rabbis. While the authorship of the later texts is more or less clear, the one of the Torah is highly problematic, also in the (...) self-understanding of Jewish hermeneutics. This question is discussed in the present paper not from a philological-historical point of view, but from a semiotic one, trying to understand what devices and regimes of enunciation are enacted by the text in order to establish its semiotic-juridical effects. A special double enunciation frame is proposed as the mark of the legislative power in the text, in correlation with another textual device, a sort of divine “signature”. The further evolution of the authorship of the Jewish Law is discussed in its relation with the question of the autonomy in the interpretation of the sacred text. (shrink)

The Cyrenaic school of philosophy (named after its founder Aristippus’ native city of Cyrene in North Africa) flourished in the fifth and fourth centuries BCE. Ugo Zilioli’s book provides the first book-length introduction to the school in English. The book begins by introducing the main figures of the Cyrenaic school beginning with Aristippus and by setting them into their historical context. Once the reader is familiar with those figures and with the genealogy of the school, the book offers an overview (...) of ancient and modern interpretations of the Cyrenaics, to provide readers with alternative accounts of the doctrines they endorsed and of the role they played in the context of ancient thought. Finally, the book offers a reconstruction of Cyrenaic philosophy and shows how the ethical side of their speculation connected with the epistemology and ontology they endorsed and that, as a result, the Cyrenaics were able to offer a quite sophisticated philosophy. Indeed, Zilioli demonstrates that they represented, in ancient philosophy, an important and original metaphysical position and alternative to the kind of realism endorsed by Plato and Aristotle.

It is an aggregation of documents and reports that have been elaborated throughout the first year of the ECS project, with a community of practice of citizen science educators and trainers, the European Citizen Science Association and the ECS consortium. They set the stage to the co-creation of the ECS Academy. The ECS Academy is a (...) work package within the European Citizen Science (ECS) project. It seeks to promote citizen science within various stakeholder spheres, countries, by being a point of reference for training material and by regrouping a community of practice around citizen science training and education to develop training needs.

This article develops the idea that Lévi-Strauss’ thought was shaped all at once in the encounter with structural linguistics. Nevertheless, Lévi-Strauss’s readers know that his writings show blunt passages from a level of discourse that refers to the project of scientific modernity (accretion of knowledge and pursuit of generality) to one announcing the dissolution of culture into physicochemical phenomena (here defined as ultramodern level), and from these two to a language usually defined as “literary”. The latter corresponds to a language (...) which articulates the themes of loss, memory, yearning for the primitive, the concerns about the demographic and environmental transformations of the planet, and an “exaggerated” contact of cultures: themes which all persist in Lévi-Strauss’ thought since its shaping as a “structuralist” one, which have been highly controversial and that could be defined as “antimodern”. Accordingly, this article tries to produce a reading of Lévi-Strauss’ work as articulated on three levels, which persist in Lévi-Strauss’s thought since its early structuralist formation: three “musical staffs” on which his modernity, ultra-modernity and anti-modernity seem all to flow at the same time.
