We consider two players each of whom attempts to predict the behavior of the other, using no more than the history of earlier predictions. Behaviors are limited to a pair of options, conventionally denoted by 0, 1. Such players face the problem of learning to coordinate choices. The present paper formulates their situation recursion theoretically, and investigates the prospects for success. A pair of players build up a matrix with two rows and infinitely many columns, and are said to “learn” (...) each other if cofinitely many of the columns show the same number in both rows (either 0 or 1). Among other results we prove that there are two collections of players that force all other players to choose their camp. Each collection is composed of players that learn everyone else in the same collection, but no player that learns all members of one collection learns any member of the other. (shrink)

This study investigates contemporary Mayan oral stories through the lens of Julian Jaynes's theory on the origin of consciousness, aiming to identify a potential connection between the literary elements of these narratives and traits of pre‐consciousness outlined by Jaynes. Jaynes's neuropsychological thesis argues that human consciousness emerged around 3000 years ago after a period of “bicameral mind,” characterized by auditory “hallucinations” that guided non‐habitual behavior. He claims that remnants of bicameral mentality linger to this day in all cultures. While his (...) theoretical framework has been applied to cultures in Europe, the Middle East, and Asia, this research uniquely surveys early Mayan texts and focuses on 78 oral narratives from Lake Atitlán, Guatemala. Our findings reveal traces of bicamerality, evident in the gradual fading of inner voices replaced by divination, anomalous mental states, encounters with the supernatural, and spiritual possession. Contrary to pathologizing these phenomena, the narratives often present them as abilities the Maya may not have felt culturally compelled to suppress to the extent presumed in other societies.

The Covid-19 pandemic has been analysed and discussed from many disciplinary perspectives. An aspect that still needs critical exploration is the role—that is, the modes and forms—of regulatory interventions during the pan- demic. It is interesting to note in this regard that, in many studies, regulatory measures are labelled “non-pharma- ceutical interventions”, as if they do not have any specificity on their own and only represent a theoretically residual category. The main aim of this article is instead to focus on (...) the distinctive features of normative measures as such. As regards the article’s focus, it centres on the normative interventions in the first period of the pandemic—that is, 2020—with particular reference to Italy. We have chosen to focus on this period because the most extensive and severe restrictions introduced to combat Covid-19 were established at that time. And we have chosen to con- sider Italy because it was the first country, after China, to be hard hit by the virus and to react in a draconian manner. As regards the methodology, the article is based, in general and primarily, on an extensive interdisciplinary literature review. With reference to the Italian case, the study is additionally based on: first-hand data collection and analysis (especially concerning Italian normative measures mainly issued at the national level: their type, frequency, target, hierarchical relationships); second-hand data and analysis (for instance as regards the effectiveness of Italy’s and other countries’ regulatory measures). In discussing the Italian response to the Covid-19 pandemic, certain weaknesses have been identified; and possible lessons have been highlighted, in terms of both “planning” (i.e. the necessity to better pre-define concrete and circumscribed sets of actions) and of “meta-planning” (i.e. the necessity of better planning the way in which public authorities could and should plan and act). Although this article is mainly based on the Italian situation, what we can learn from this case is largely generalizable. (shrink)

This trilogy deals with an epistemology of economics, arguing for a radical overturning of conventional analysis and providing an alternative to political economy and social sciences, based not on positivism, but on a normative and programming paradigm. Volume II builds on the work presented in Volume I to explore oppositions to the traditional and conventional teaching of economics, and presents testimonies that are favourable to a trend towards a programming approach, thereby giving substance to the epistemological 'overturning' of conventional analysis. (...) Such oppositions studied include the work of Ludvig von Mises and his theory of praxeology; Ian Tinbergen and Wassily Leontif's preference for 'planning' over 'forecasting science'; Bruno de Finetti and Daniel Bell's support for the base of 'utopia' in economics; the trend from the 'theory of planning' towards the 'methodology of planning, by Andreas Faludi; neoclassic curiosity about the 'multi-purposes approach' and 'non-economic commodities' as investigated by Walter Isard, as well as theories expressed by Herbert Simon, Robert Lucas, George Soros and Mark Blaug. Volume III takes studies further and presents a concrete and practical example of how to build a Planning Accounting Framework, as associated with Frisch's 'plan-frame', to demonstrate the extent to which decisions and negotiations can be routed in the social sciences.

Paul Franco’s book, "Nietzsche’s Enlightenment: The Free-Spirit Trilogy of the Middle Period," offers a close study of Nietzsche's middle period works, revealing a Nietzsche attentive to the concerns that motivated the European Enlightenment that Franco references in his title. Franco aims to show that a concern with science, reason, and truth remains important to Nietzsche in his post-Gay Science works. That is, although Nietzsche is most at home in the Enlightenment tradition during his middle period, he never (...) abandoned this aspect of his thought for a wholesale rejection of science, human reason, and the possibility of truth, as some readers of Nietzsche suggest. Franco suggests that the free spirit ideal that animates the middle period remains a vital element of Nietzsche’s thought throughout his mature work, marking the ideals expounded there. (shrink)

Accompagnée d’une aspiration générale à une plus grande égalité entre les sexes et d’une remise en cause de l’autorité paternelle, le dernier tiers du xxe siècle a été une période de transformation profonde et rapide des organisations familiales traditionnelles.

This book starts with the proposition that digital media invite play and indeed need to be played by their everyday users. Play is probably one of the most visible and powerful ways to appropriate the digital world. The diverse, emerging practices of digital media appear to be essentially playful: Users are involved and active, produce form and content, spread, exchange and consume it, take risks, are conscious of their own goals and the possibilities of achieving them, are skilled and know (...) how to acquire more skills. They share a perspective of can-do, a curiosity of what happens next? Play can be observed in social, economic, political, artistic, educational and criminal contexts and endeavours. It is employed as a strategy, for tacit or open resistance, as a method and productive practice, and something people do for fun. The book aims to define a particular contemporary attitude, a playful approach to media. It identifies some common ground and key principles in this novel terrain. Instead of looking at play and how it branches into different disciplines like business and education, the phenomenon of play in digital media is approached unconstrained by disciplinary boundaries. The contributions in this book provide a glimpse of a playful technological revolution that is a joyful celebration of possibilities that new media afford. This book is not a practical guide on how to hack a system or to pirate music, but provides critical insights into the unintended, artistic, fun, subversive, and sometimes dodgy applications of digital media. Contributions from Chris Crawford, Mathias Fuchs, Rilla Khaled, Sybille Lammes, Eva and Franco Mattes, Florian 'Floyd' Mueller, Michael Nitsche, Julian Oliver, and others cover and address topics such as reflective game design, identity and people's engagement in online media, conflicts and challenging opportunities for play, playing with cartographical interfaces, player-emergent production practices, the re-purposing of data, game creation as an educational approach, the ludification of society, the creation of meaning within and without play, the internalisation and subversion of roles through play, and the boundaries of play.

In GS, Nietzsche utters for the first time the paradoxical formula that sums up a good deal of his ethical thought: "What does your conscience say?—'You should become who you are'".1 The paradox, of course, lies in the odd juxtaposition of becoming and being: how can one become what one already is? Nietzsche repeats the formula toward the end of the original edition of GS, connecting it explicitly to the idea of self-creation: "We, however, want to become who we are—human (...) beings who are new, unique, incomparable, who give themselves laws, who create themselves!". What exactly such self-creation involves for Nietzsche, how it relates to "who we are," and whether it ultimately coheres as a... (shrink)

Taking a cue from remarks Thomas Kuhn makes in 1990 about the historical turn in philosophy of science, I examine the history of history and philosophy of science within parts of the British philosophical context in the 1950s and early 1960s. During this time, ordinary language philosophy's influence was at its peak. I argue that the ordinary language philosophers' methodological recommendation to analyze actual linguistic practice influences several prominent criticisms of the deductive-nomological model of scientific explanation and that these criticisms (...) relate to the historical turn in philosophy of science. To show these connections, I primarily examine the work of Stephen Toulmin, who taught at Oxford from 1949 to 1954, and Michael Scriven, who completed a dissertation on explanation under Gilbert Ryle and R.B. Braithwaite in 1956. I also consider Mary Hesse's appeal to an ordinary language-influenced account of meaning in her account of the role of models and analogies in scientific reasoning, and W.H. Watson's Wittgensteinian philosophy of science, an early influence on Toulmin. I think there are two upshots to my historical sketch. First, it fills out details of the move away from logical positivism to more historical- and practice-focused philosophies of science. Second, questions about linguistic meaning and the proper targets and aims of philosophical analysis are part and parcel of the historical turn, as well as its reception. Looking at the philosophical background during which so-called linguistic philosophers also had a hand in bringing these questions to prominence helps us understand why. (shrink)

This paper is devoted to the algebraization of an arithmetical predicate introduced by S. Feferman. To this purpose we investigate the equational class of Boolean algebras enriched with an operation (g=rtail), which translates such predicate, and an operation τ, which translates the usual predicate Theor. We deduce from the identities of this equational class some properties of (g=rtail) and some ties between (g=rtail) and τ; among these properties, let us point out a fixed-point theorem for a sufficiently large class of (...) (g=rtail)-τ polynomials. The last part of this paper concerns the duality theory for (g=rtail)-τ algebras. (shrink)

This research examined choice behaviour and probability judgement in a counterintuitive reasoning problem called the Monty Hall problem (MHP). In Experiments 1 and 2 we examined whether learning from a simulated card game similar to the MHP affected how people solved the MHP. Results indicated that the experience with the card game affected participants' choice behaviour, in that participants selected to switch in the MHP. However, it did not affect their understanding of the objective probabilities. This suggests that there is (...) dissociation between implicit knowledge gained from the task and the explicit understanding as to why switching was the best strategy. In Experiment 3, the number of prizes and doors were manipulated to examine how participants construed the problem space of the MHP. Results revealed that participants partition the probability judgement to reflect the number of prizes over the number of unopened doors. (shrink)

We characterize the sets of all Π2 and all equation image theorems of IΠ−1 in terms of restricted exponentiation, and use these characterizations to prove that both sets are not deductively equivalent. We also discuss how these results generalize to n > 0. As an application, we prove that a conservation theorem of Beklemishev stating that IΠ−n + 1 is conservative over IΣ−n with respect to equation image sentences cannot be extended to Πn + 2 sentences. © 2011 WILEY-VCH Verlag (...)

Let T be a second-order arithmetical theory, Λ a well-order, λ < Λ and X ⊆ ℕ. We use $[\lambda |X]_T^{\rm{\Lambda }}\varphi$ as a formalization of “φ is provable from T and an oracle for the set X, using ω-rules of nesting depth at most λ”.For a set of formulas Γ, define predicative oracle reflection for T over Γ ) to be the schema that asserts that, if X ⊆ ℕ, Λ is a well-order and φ ∈ Γ, then$$\forall \,\lambda (...) < {\rm{\Lambda }}\,.$$In particular, define predicative oracle consistency ) as Pred–O–RFN{0=1}.Our main result is as follows. Let ATR0 be the second-order theory of Arithmetical Transfinite Recursion, ${\rm{RCA}}_0^{\rm{*}}$ be Weakened Recursive Comprehension and ACA be Arithmetical Comprehension with Full Induction. Then,$${\rm{ATR}}_0 \equiv {\rm{RCA}}_0^{\rm{*}} + {\rm{Pred - O - Cons\ }}\left \equiv {\rm{RCA}}_0^{\rm{*}} + \,{\rm{Pred - O - Cons\ }}\left \equiv {\rm{RCA}}_0^{\rm{*}} + \,{\rm{Pred - O - RFN}}\,_{{\bf{\Pi }}_2^1 } \left.$$We may even replace ${\rm{RCA}}_0^{\rm{*}}$ by the weaker ECA0, the second-order analogue of Elementary Arithmetic.Thus we characterize ATR0, a theory often considered to embody Predicative Reductionism, in terms of strong reflection and consistency principles.

A searing introduction to Franco Fortini, a Jewish communist and a major figure in postwar Italian intellectual life, _The Dogs of the Sinai_ is a book against—against those who love to rush to the aid of the victors, against the widespread and racist contempt for Arabs, and against the celebration of modern civilization and technology that Israel embodies. It is also the book in which Fortini sought to clarify for himself his conflicted identity as an Italian Jew. An uncomfortably (...) timely book, _The Dogs of the Sinai_ combines polemic and autobiography with narrative and criticism in a terse and finely wrought reflection on politics, identity, and truthfulness in the period after the Six Day War of 1967. As topical today as it was forty-five years ago, this meditation against power is published alongside _Fortini/Cani_, a film by Jean-Marie Straub and Danièle Huillet, drawn from Fortini’s essay. The film includes moving scenes of the author reading excerpts from his book against quiet landscapes. _The Dogs of the Sinai_ is a powerful text from one of the most important intellectuals of the Italian New Left.

As COVID-19 emerged as a phenomenon of the total environment, and despite the intertwined and complex relationships that make humanity an organic part of the Bio- and Geospheres, the majority of our responses to it have been corrective in character, with few or no consideration for unintended consequences which bring about further vulnerability to unanticipated global events. Tackling COVID-19 entails a systemic and precautionary approach to human-nature relations, which we frame as regaining diversity in the Geo-, Bio-, and Anthropospheres. Its (...) implementation requires nothing short of an overhaul in the way we interact with and build knowledge from natural and social environments. Hence, we discuss the urgency of shifting from current to precautionary approaches to COVID-19 and look, through the lens of diversity, at the anticipated benefits in four systems crucially affecting and affected by the pandemic: health, land, knowledge and innovation. Our reflections offer a glimpse of the sort of changes needed, from pursuing planetary health and creating more harmonious forms of land use to providing a multi-level platform for other ways of knowing/understanding and turning innovation into a source of global public goods. These exemplary initiatives introduce and solidify systemic thinking in policymaking and move priorities from reaction-based strategies to precautionary frameworks. (shrink)

In this paper, I look at Susan Stebbing’s articles and reviews that critically engage logical positivism. These appeared before the publication of A.J. Ayer’s Language, Truth and Logic and helped shape the early British reception of logical positivism. I highlight Stebbing’s adoption of G.E. Moore’s tripartite distinction between knowing a proposition, understanding it, and giving an analysis of it and, in light of this distinction, her focus on whether the principle of verifiability can ground a plausible account of communication. Stebbing (...) thinks not, and I reconstruct her reasons, as well as her own account of communication. In doing this, I relate her criticisms to her rejection of methodological solipsism and her dissatisfaction with the logical positivist treatment of statements about other minds and the past. I also argue that Stebbing’s work provides a bridge to later criticisms of logical positivism from ordinary language philosophers. Foregrounding Stebbing’s engagement with logical positivism, especially her focus on communication, paints a fuller picture of how the logical positivists came to be part of analytic philosophy despite having different concerns than many of the British philosophers engaging their work.

This article casts light on the moral implications of the possibility of human extinction, with a specific focus on extinction caused by an interruption in human reproduction. In the first two paragraphs, I show that moral philosophy has not yet given promising explanations for the wrongness of this kind of extinction. Specifically, the second paragraph contains a detailed rejection of John Leslie’s main claims on the morality of extinction. In the third paragraph, I offer a demonstration of the fact that (...) a moral view which stresses the permissibility of some types of human extinction can be effectively constructed, while in the following paragraph I propose a prima facie defense of a new approach to the topic which is likely to provide us with reasons in favor of the wrongness of a premature departure of humankind.

This paper investigates the status of the fragments of Peano Arithmetic obtained by restricting induction, collection and least number axiom schemes to formulas which are $${\Delta_1}$$ provably in an arithmetic theory T. In particular, we determine the provably total computable functions of this kind of theories. As an application, we obtain a reduction of the problem whether $${I\Delta_0 + \neg \mathit{exp}}$$ implies $${B\Sigma_1}$$ to a purely recursion-theoretic question.

Infants initiate joint attentional exchanges by pointing relevant referents out to addressees. Over the second year of life, the functional meaning of the pointing gesture develops from declarative (sharing a referent) to informational (giving some information that is new to the addressee). This chapter analyzes this transition in the development of pointing based on experimental evidence about its production contexts and, in particular, of variables concerning the visibility of referents for infant and addressee. Further evidence is reported concerning the association (...) of pointing with vocalizations and visual checking towards the addressee in different temporal sequencing. It is argued that shared attention initiated by pointing plays a pivotal role in the intersection between social cognition and language development. (shrink)

This paper presents the Futurium platform used by Digital Futures, a foresight project launched by the European Commission's Directorate General for Communications Networks, Content and Technology (DG CONNECT). Futurium was initially developed with the primary purpose of hosting and curating visions and policy ideas generated by Digital Futures (Digital Futures was launched in July 2011 by DG CONNECT's Director General Robert Madelin following a prior DG CONNECT exercise called Digital Science.). However, it has turned into a platform on which to (...) experiment with new policymaking models based on scientific evidence and stakeholder participation, referred to in this paper as ‘Policy Making 3.0’. The platform hosts an online foresight toolkit to facilitate the joint creation of ideas to help design future policies. It leverages the potential of social networks, open data, semantic and knowledge mining technologies as well as participatory brainstorming techniques to engage stakeholders and harness their views and creativity to better inform policies that matter to them. The Futurium distinguishes between different variables, reflecting the emotional vs. rational mindsets of the participants, and offers the possibility to frame the engagement and co-creation process into multiple phases of a workflow. Futurium was developed to support Digital Futures, but its open architecture makes it easily adaptable to any policymaking/decision-making context where thinking ahead, participation, scientific evidence and agility are needed. Futurium is an early prototype implementation of the Policy Making 3.0 model, which is a long-term vision requiring further investigation and experimentation. The Futurium production website can be seen here: ec.europa.eu/digital-agenda/futurium. (shrink)

Basilio Sabazio was the first in Italy to argue for the unity and corruptibility of either sublunar or celestial matter. In this paper new insight of his intellectual activity between Napoli and Milano is provided, and in particular his relationship with Scipione Capece, from whose letter to Giovan Francesco di Capua, Count of Palena we learn that Sabazio was an expert in philology and astronomy. The surviving part of an essay by Sabazio to the astronomer Francesco Cigalini from Como is (...) here edited with some informations about Cigalini’s reply. A newly recovered Sabazio’s astronomical work is here edited – from which his endorsement of Eraclides Ponticus’ astronomical system is evident –, as well as his Consilium to Pope Paolo III about the urgency of convening a general council.

The present work introduces the neuropsychological paradigm as a new approach to studying ancient literature. In the first part of the article, an epistemological framework for the proper use of neuropsychology in relation to ancient literature is presented. The article then discusses neuropsychological methods of studying different human experiences and dimensions already addressed by ancient literatures. The experiences of human encounters with gods among ancient cultures are first considered, through the contributions of Julian Jaynes and Eric R. Dodds. The concepts (...) of right and left in the Bible, and that of soul are then discussed. Ecstatic experience in Paul of Tarsus is also presented, with a particular focus on glossolalia. Neuroscientific differences between mindful and unitive meditative practices are then described referring to ancient Buddhist literature, and finally a brief description of dreams in ancient Greek literature is proposed. Neuropsychology variously enables a more profound understanding of themes characterizing human experiences that ancient literature has already explored; these investigations prove that the collaboration of neuroscience and humanistic studies can return fruitful and interesting results.

This paper concerns late 1920 s attempts to construct unitary theories of gravity and electromagnetism. A first attempt using a non-standard connection—with torsion and zero-curvature—was carried out by Albert Einstein in a number of publications that appeared between 1928 and 1931. In 1929, Tullio Levi-Civita discussed Einstein’s geometric structure and deduced a new system of differential equations in a Riemannian manifold endowed with what is nowadays known as Levi-Civita connection. He attained an important result: Maxwell’s electromagnetic equations and the gravitational (...) equations were obtained exactly, while Einstein had deduced them only as a first order approximation. A main feature of Levi-Civita’s theory is the essential use of the Ricci’s rotation coefficients, introduced by Gregorio Ricci Curbastro many years before. We trace the history of Ricci’s coefficients that are still used today, and highlight their geometric and mechanical meaning. (shrink)

This article reviews empirical evidence and ethical norms in cross-linguistic nursing. Empirical evidence highlights that linguistic barriers between nurses and patients can perpetuate discrimination and compromise nursing care. There are significant organizational and relational challenges involved in ensuring adequate use of interpreters by nurses. Some evidence suggests that linguistic barriers are particularly problematic for nurses when compared with physicians. A comparative analysis of nursing ethical norms for cross-linguistic nursing was conducted using the codes of ethics of the American Nurses Association, (...) the Canadian Nurses Association, and the International Council of Nurses. Five principal ethical norms for cross-linguistic nursing were identified: (1) respect for the patient as a unique person; (2) respect for the patient’s right to self-determination; (3) respect for patient privacy and confidentiality; (4) responsibility for one’s own competence, judgment, and action; and (5) responsibility to promote action better to meet the needs of patients, families, and groups.

Un debat tres vif eut lieu parmi les commentateurs medioplatoniciens sur le rapport entre la forme du bien de la Republique et le demiurge du Timee. Certains d’entre eux, comme Plutarque et Atticus, parvinrent a identifier ces deux entites, d’autres, comme Numenius, a situer les deux principes dans une relation hierarchique, en attribuant au bien la qualification de ≪premier dieu≫ et de pere et au demiurge celle de ≪second dieu≫ et de producteur. Cet article se propose d’examiner la question de (...) l’identite de la forme du bien avec le demiurge sur des bases nouvelles, en prenant comme point de depart une interpretation metaphorique de la figure du demiurge, qui ne se presente pas comme un principe metaphysique independant, mais comme une description metaphorique de l’element causal‑efficient du monde des formes, c’est a dire du vivant intelligible. Le demiurge coinciderait donc avec la totalite active et dynamique du monde intelligible. Dans la seconde partie de l’article est prise en consideration l’hypothese que la superiorite de la forme du bien par rapport aux autres formes est du meme genre que celle du demiurge, dans la mesure ou le bien aussi peut etre compris comme la totalite du kosmos intelligible. Il s’agit d’une hypothese qui ne va pas sans difficultes, mais qui merite d’etre examinee jusqu’au bout. (shrink)

This article compares the political philosophies of Michael Oakeshott and Isaiah Berlin, probably the two most important political philosophers in postwar Britain, who, strangely, had very little to do with one another during their illustrious careers. The article focuses on their respective critiques of rationalism and theories of liberal pluralism, arguing that Oakeshott provides the more consistent and philosophically satisfying account in both instances.

En este artículo se aborda la identidad personal desde la perspectiva de Derek Parfit, a través de un contraste filosófico entre el planteamiento de la esencialidad y las concepciones fenomenológicas de esta misma.

Es por ello que abordar la identidad personal desde el tenor psicologista permite establecer argumentos que aporten (...) a la relevancia de la memoria como factor pertinente del problema identitario, gracias a las contribuciones de la filosofía parfitiana que sostiene la variabilidad y perdurabilidad en el tiempo como determinantes de la identidad personal. Esto significa que podremos entender la identidad personal desde una apreciación del pasado, más que una determinación del futuro. (shrink)

Although the term ontology is absent from Plato’s works, his thinking undoubtedly belongs to the prehistory of this discipline. In his dialogues, one finds many observations concerning what exists and how it exists. Plato’s metaphysics is based on the fundamental distinction between two kinds of entities, namely intelligible forms and sensible particulars. This diairesis is presented in different but all compatible ways. The ontological difference between forms and sensible objects implies a causal priority: according to Plato, this priority corresponds to (...) the proteron-hysteron scheme mentioned by Aristotle. The last part of the essay is devoted to the idea of the good and the problems related to its ontological status. (shrink)

This paper focuses on Anaximander's pinax, the first map according to Western tradition. Its aim is to demonstrate that it is only after the realization of the pinax that it was possible to distinguish between Being and beings in a Heideggerian sense, that is to pose the question of the ontological difference. Consequently, all the history of Western thought is nothing but the history of the raising of cartographical representation, and of reason here embodied, from the dark rigidity of death (...) to the rarefied splendours of Pure Reason.
