This study aims to investigate the hypothesis that “thinking in opposites” might facilitate insight problem solving. For example, if the image relating to a problem is oriented horizontally, it may...

A focused review of the literature on reasoning suggests that mechanisms based upon contraries are of fundamental importance in various abilities. At the same time, the importance of contraries in the human perceptual experience of space has been recently demonstrated in experimental studies. Solving geometry problems represents an interesting case as both reasoning abilities and the manipulation of perceptual–figural aspects are involved.In this study we focus on perceptual changes in geometrical problem solving processes in order to understand whether a mental (...) manipulation in terms of opposites might help. Four conditions were studied, two of which concerned the search for contraries as an implicit or explicit strategy.Results demonstrated that contraries, when used explicitly in solution processes, constitute an effective heuristic: The number of correct solutions increased, less time was needed to find a solution and participants were oriented towards the use of perception-based solutions—not only wer..

Questo primo volume degli "Scritti di Ugo Bianchi" - "Religions in Antiquity" - raccoglie contributi relativi a temi e problemi del cristianesimo antico. Con esso si realizza un progetto, formulato in anni lontani (1983) dallo stesso autore, che contemplava varie sezioni di cui l'ultima - "Christiana" comprendeva i saggi che costituiscono la prima metà del volume; a questi ne sono stati aggiunti altri, sulle medesime tematiche, che risalgono ad anni successivi. Precede i saggi un contributo di carattere metodologico ("Tipologia (...) storica delle religioni e comparazione: il caso del dualismo"). "Ugo Bianchi, nel suo lungo itinerario scientifico che abbraccia alcune delle più significative aree del vasto panorama delle esperienze religiose della storia umana, non ha mai proposto una "teoria" interpretativa generale e onnicomprensiva di esse, quale molto spesso - con esiti e fortune diversi hanno fatto tanti storici delle religioni. Egli, al contrario, ha mostrato riserbo o vera e propria diffidenza nei confronti di tali "teorie" che il progresso della ricerca e la riflessione critica hanno sempre in varia misura smentito o ridimensionato. Di fatto, lo studioso ha costantemente riconosciuto la debolezza intrinseca di tali tentativi alla luce delle mobili e differenziate realtà che la storia ci consegna e che solo a prezzo di un'analisi comparativa condotta con duttilità e rigore..."

The idea of presenting the correspondence between Ioan Petru Culianu and Ugo Bianchi involves reviewing the topics specific to Bianchi’s school of History of Religion for a period of more than a decade and the manner in which the Romanian-born historian of religions builds his academic career. The academic relation between Bianchi and Culianu has a major common point: an acute preoccupation with the epistemological construction of the HR discipline. What is it that separates Culianu from (...) class='Hi'>Bianchi and even from a large majority of the academic community in his ultimate view on religion and the religious phenomena? From a historical and religious point of view, the answer is very simple: Culianu developed a holistic theory about religion whose conceptual directions led to what Bianchi called reductio ad unum. This article focuses on presenting the biographical data correlated to the most solid scholarly education that Culianu ever had in Italy. I will also reiterate the idea that the centre of gravity of Culianu’s ultimate concerns does not necessarily fall on the methodological disputes of HR, but especially on a new understanding of cognitive sciences in general.

Slurs are derogatory terms targeting individuals and groups of individuals on the basis of race, nationality, religion, gender or sexual orientation. The aim of my paper is to propose an account of appropriated uses of slurs – i.e. uses by targeted groups of their own slurs for non-derogatory purposes, as in the appropriation of ‘nigger’ by the African-American community, or the appropriation of ‘queer’ by the homosexual community. In my proposal appropriated uses are conceived as echoic, in Relevance Theory terms: (...) in-groups echo derogatory uses in ways and contexts that make manifest the dissociation from the offensive contents. I will show that the echoic strategy has interesting advantages over alternative theories, and especially over Anderson and Lepore’s deflationary strategy. (shrink)

In this contribution, I explore the treatment that Plato devotes to Protagoras’ relativism in the first section of the Theaetetus (151 E 1–186 E 12) where, among other things, the definition that knowledge is perception is put under scrutiny. What I aim to do is to understand the subtlety of Plato’s argument about Protagorean relativism and, at the same time, to assess its philosophical significance by revealing the inextric¬ability of ontological and epistemological aspects on which it is built (for this (...) latter aspect, I refer to contemporary discussions of relativism, mainly to Margolis’ robust relativism). I then turn to Aristotle’s treatment of Protagoras’ relativism in Metaphysics Γ, sections 5 and 6, in order to show that Plato and Aristotle surprisingly share the same view as regards the philosophical content of Protagoras’ relativism (in doing so, I take position against the standard opinion among scholars that Plato and Aristotle understand Protagoras’ relativism in different, even incompatible, ways). What I ultimately aim to demonstrate is that Protagoras’ relativism, as understood by both Plato and Aristotle, is a coherent, even attractive, philosophical position. (shrink)

This paper deals with an important strand of nihilistic arguments to be found in the works of two philosophers who have so far never been studied comparatively: the sophist Gorgias and the Buddhist monk Nāgārjuna. After having reconstructed Gorgias' moves in the first section of On What is Not (Sections 1-4), the paper shows how the nihilist arguments Gorgias uses mostly feature, under a new light, in the philosophy of emptiness developed by Nāgārjuna (Sections 5-8). The paper ends with a (...) hermeneutical suggestion: that is, to replace traditional ‘sceptical’ interpretations of Gorgias and Nāgārjuna with an alternative one, which takes them as possibly committed to nihilism.

In this paper I offer a reconstruction of the account of meaning and language the Cyrenaics appear to have defended on the basis of a famous passage of Sextus, as well as showing the philosophical parentage of that account.

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”.

Founding our analysis on the Geneva-Brussels approach to quantum mechanics, we use conventional macroscopic objects as guiding examples to clarify the content of two important results of the beginning of twentieth century: Einstein–Podolsky–Rosen’s reality criterion and Heisenberg’s uncertainty principle. We then use them in combination to show that our widespread belief in the existence of microscopic particles is only the result of a cognitive illusion, as microscopic particles are not particles, but are instead the ephemeral spatial and local manifestations of (...) non-spatial and non-local entities.

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.

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.

Different disciplines have analyzed binary choices to model collective behavior in human systems. Several situations in which social dilemma arise can be modeled as N-person prisoner’s dilemma games including homeland security, public goods, international political economy among others. The purpose of this study is to develop an analytical solution to the N-person prisoner’s dilemma game when boundedly rational agents interact in a population. Previous studies in the literature consider the case in which cooperators and defectors have the same learning factors. (...) We obtain an analytical equation to find equilibria in the N-person prisoner’s dilemma game in the general case when agents have different learning factors. We also introduce a more realistic approach where probability values are bounded between zero and one and therefore eliminates the possibility of infeasible probability values. Since no analytic solution can be derived in this case, agent based simulation is used to analyze the asymptotic behavior of the resulted dynamical system. (shrink)
