We define the notion of Euler characteristic for definable quotients in an arbitrary o-minimal structure and prove some fundamental properties.

The paper discusses the Anglo-American philosophy of law of the 20th century, more specifically the philosophy of law of Ronald Myles Dworkin and his criticism of the legal positivism of Herbert Lionel Adolphus Hart. The author presents the history of the criticism of legal positivism in Ronald Dworkin’s philosophy of law and distinguishes historical stages. The subject of the study is the critique of legal positivism but not the Hart-Dworkin debate itself, well known in Western philosophy of law. The reason (...) is that the discussion was conducted between Dworkin and Hart’s supporters but not between Dworkin and Hart by himself. The latter responded to the criticism only after twenty seven years. The article explains why Dworkin chose for his criticism Herbert Hart’s version of legal positivism. This is due to the fact that Dworkin highly appreciated Hart’s positivist theory of law and characterized it as the “most clear.” The article presents the methodological foundations of criticism of Hart’s legal positivism in Dworkin’s philosophy of law. It reveals a methodological divergence between the two legal theories, which directly affects the understanding of the concept of law and its content. Therefore, we can assume that the legal theories of Hart and Dworkin are two competing models of law: Dworkin’s model considers law as a set of rules and principles and Hart’s model acknowledges only rules and court decisions as a source of law. The article also presents the key principles of positivism criticized by Dworkin. These principles, firstly, interpret law as a set of legal rules determined through a special legal criterion, secondly, provide the judge with an opportunity to make a decision “at his own discretion” in a situation not regulated by law, and, thirdly, recognize only legal rights and obligations enshrined in legal regulations. It is important to note that in this article the author describes criticism as an independent phenomenon of legal philosophy with a particular focus on the history and foundations of this phenomenon.

Islamic environmentalism is an intellectual movement whose representatives discuss contemporary environmental problems in the language of Islamic theology. This field includes Shariah-based environmental law, environmental activism, and environmental philosophy. This article is an overview of the genealogy of this philosophical trend: key names will be listed and their contributions to the development of this movement will be analyzed. For example, the legacy of Sayyid Hossein Nasr, considered the founding father of Islamic environmentalism, will be examined in detail. The religious and (...) ethical program of this philosophical movement will be analyzed in detail. The categorical apparatus to which Islamic eco-activists, philosophers, and ulema turned as the Islamic environmental agenda expanded will also be examined, such as how the concepts of khalifa, hima, and misan were conceptualized. Philosophers whose writings we will turn to include Iraqi philosopher and jurist Mawil Izzi Dien, British eco-activist Fazlun Khalid, Egyptian Grand Mufti Ali Jumaa, and representatives of so-called “Western Islam” Ziauddin Sardar and Tariq Ramadan. The example of Indonesia will be used to examine how Islamic eco-theology has formed the basis of a multilevel environmental policy. The thesis of the fundamental contradiction underlying Islamic environm entalism is put forward. On the one hand, this movement in its present form genetically dates back to the European protest movements of the 1960s and 70s, which opposed the culture of mass consumption, impersonal materialism, and overproduction. On the other hand, an equally important part of the rhetoric of a number of Islamic modernists, including on ecology, is the emphasis on the break with Western neoliberal values. The special role of social media in the promotion of Islamic eco-activism is noted separately. (shrink)

This article aims at contributing to the contemporary reception of Heidegger’s thought in eco-philosophical perspective. Its point of departure is Heidegger’s claim, in his Bremen lectures and The Question Concerning Technology, that today the earth is submitted to permanent requisition and planned ordering, and that, having thus lost sight of its auto-poiesis, we are no longer capable of listening, tuning in, and singing back to what he calls in his course on Heraclitus the “song of the earth.” Accordingly, first we (...) examine how the inherently reciprocal dynamics of “earth” and “world,” as thematised by Heidegger in The Origin of the Work of Art, have become opaque. Second, we analyse whether it is possible to find those same dynamics at play behind Heidegger’s “Fourfold,” which we propose to reread in binary key in dialogue with contemporary anthropology, from Bateson and Lévi-Strauss to Wagner and Viveiros de Castro, and in light of Guattari’s notion of “trans-entitarian generativity.” Third, we stress the need to reposition Heidegger’s thought alongside contemporary concerns on “worlding” and we explore its plausible intersections with today’s object-oriented ethnography. Lastly, we discuss the possibility of rereading Heidegger’s Fourfold afresh against the backdrop of Heidegger’s non-foundational thinking, as a conceptual metaphor for the joint dynamics of Abgrund and Grund.

Our purpose in this study – which stands at the crossroads of contemporary philosophy, anthropology, and religious studies – is to assess critically the plea for radical contingency in contemporary thought, with special attention to the work of Meillassoux, in light, among other things, of the symptomatic presence of Pauline motifs in the late twentieth to early twenty first-century philosophical arena, from Vattimo to Agamben and especially Badiou. Drawing on Aristotle’s treatment of τύχη and Hilan Bensusan’s neo-monadology (as well as (...) on the network biology of David George Haskell, Scott Gilbert’s holobiont hypothesis, and Terrence Deacon’s teleo-dynamics), we ask what is missing in such plea, from a theoretical standpoint. Next, we examine the relation between radical contingency and worldlessness in dialogue with Leroi-Gourhan’s theory of biocultural evolution, Lévi-Strauss’s structural anthropology, Pierre Clastres’s ethnography, Heidegger’s philosophy of language, and contemporary authors like Eduardo Viveiros de Castro and Patrice Maniglier. These two parallel lines of inquiry help us explore what radical contingency, in turn, prevents us from thinking: the intersection of ontology, cosmopolitics, and modality. (shrink)

The home environment is a particularly significant part of life that is supposed to satisfy inhabitants’ needs, form their identity, and contribute to psychological wellbeing. The construct of home attachment is especially relevant for students as a most mobile social group. This study is devoted to the validation of the Short Home Attachment Scale in a student sample from five countries. A total of 1,349 university students participated in the study and filled in the 14 items of HAS. In order (...) to avoid redundant items with high error covariances damaging the model, a new scale—the SHAS was developed by eliminating seven items. The shortened scale has satisfactory structure validity in terms of model fit in all countries except Indonesia; internal reliability values were acceptable in all countries. Measurement invariance across countries was tested with Multi-Group Confirmatory Factor Analysis and Alignment Analysis. MG CFA confirmed both configurational and metric invariance. The invariance of item factor loadings, as well as item intercepts, was also confirmed by the Alignment Analysis. The mean scores varied across cultures, with the highest in India and the lowest in Russia. The final version of SHAS is a valid, reliable tool that may be recommended for use in cross-cultural research. However, the SHAS factor structure robustness in the Indonesian population should be investigated thoroughly. (shrink)

The correlational study is aimed at validating theAuthenticity Scalein Russian culture. Authenticity is considered a trait responsible for a person’s ability to be oneself. It helps people resist environment pressure and prevent self-alienation, which contributes to maintaining psychological wellbeing. The original Authenticity Scale includes three subscales:Authentic Living, Accepting External Influence, andSelf-Alienation. In total, 2,188 respondents (Mage= 26.30,SDage= 13.81; 78.1% female) participated in the survey. The dimensionality of theAuthenticity Scaleand its measurement invariance across sex, age, and depression rate subgroups was examined (...) with exploratory and confirmatory factor analyses; the original tripartite structure was kept. Convergent validity was tested through correlation analyses with theWarwick-Edinburgh Mental Well-being Scale, theInternational Positive and Negative Affect Schedule Short-Form, theCentre of Epidemiological Studies-Depression Scale, theRosenberg Self-Esteem Scale, and theSatisfaction with Life Scale. According to the CFA results, the structure of the Russian version differs from the original one slightly (item 1 was moved from the subscaleAuthentic Livingto the subscaleAccepting External Influenceand item 4 was excluded); however, the modified factor model showed the best absolute and comparative fit statistics [CFI = 0.961, TLI = 0.949, RMSEA = 0.050 (90% CI [0.40; 0.60]) and SRMR = 0.037]. The reliability (McDonald’s Omega) of theAuthenticity Scalesubscales was satisfactory and ranged from 0.78 to 0.84. It was revealed that youth are more likely to have high scores onAccepting External InfluenceandSelf-Alienationthan adults. Men and women did not significantly differ on the sub-scores ofAuthenticity Scale. Multigroup CFA also showed thatAuthenticity Scalescores may be biased in people with high levels of clinical depression, in terms of the item intercepts.Authentic Livingis positively connected with mental wellbeing, self-esteem, positive affect, satisfaction with life, and negatively with depressive symptoms and negative affect; reverse trends were found forAccepting External InfluenceandSelf-Alienationsubscales. The Russian version of theAuthenticity Scaleis a valid, reliable tool that may be recommended for use in various areas of non-clinical practice. (shrink)

The purpose of the study is to study the demographic situation in the Russian Federation using a system of general and particular statistical indicators, to identify the problems of socio-economic policy and suggest possible ways to solve them. The article examines various factors that influenced the demographic situation in Russia in 2000-2021; demographic problems, the consequences of which affect the socio-economic life of Russian society; the demographic situation that has arisen due to the epidemiological situation in our country. The scientific (...) novelty of the research consists in considering the influence of various factors, including pandemics, on the demographic processes in the Russian Federation. As a result of the study, possible measures were proposed to improve the socio-economic policy of the state. (shrink)

This is the first complete English translation of the Jami al-hikmatayn, written in Persian, the final, and crowning, work of the great poet, philosopher, and Ismaili missionary Nasir-i Khusraw (1004-1077). Twin Wisdoms Reconciled was written at the request of the emir of Badakhshan 'Abu al-Ma'ali 'Ali ibn Asad' who was perplexed by the questions in a long philosophical ode written a century earlier by Abu al-Haytham Jurjani, an obscure Ismaili author. The ode consists of a series of some 90 questions (...) on a wide range of subjects, from logic and metaphysics to medicine, cosmology, and physics, as well as esoteric Ismaili doctrine. Nasir-i Khusraw's text takes the form of a commentary on certain astutely selected lines. Twin Wisdoms Reconciled represents yet another example of the author's lifelong endeavour to transform Persian philosophical prose into a deft and nuanced instrument of expression. The work has not been as extensively studied as Nasir-i Khusraw's other major theological and philosophical treatises, all written in his final exile in Badakhshan, in part perhaps because of its textual difficulties. Twin Wisdoms Reconciled survives in a single manuscript of dubious accuracy in the Aya Sofya collection, Suleymaniyye Library, Istanbul. The present translation is based on the critical edition of the text produced by Henry Corbin and Mohammed Mo'in in 1953, but with frequent reference to the unique original manuscript. Twin Wisdoms Reconciled represents an endeavour to reconcile two apparently opposed forms of knowledge: the knowledge accorded by revelation and exegesis and the knowledge gained by reason. Seeing that "the bazaar of wisdom" stands empty because of the mutual incomprehension of traditional theologians and Aristotelian philosophers, Nasir-i Khusraw stepped boldly forward to reinvigorate that desolate marketplace. His final work, written in 1070, is thus a testimony as well as an exposition of his mature thought. (shrink)
