The present paper deals with the notion of essence in Thomas Aquinas. Part 1 focuses on the main points of Aquinas’s doctrine of essence set out in his De ente et essentia, and especially on the concept of essence as the “form of the whole” and the concept of the “nature considered absolutely”. The comparison with the teaching of Aristotle and Aquinas’s Arabic predecessors in Part 2 shows that Thomas’s notion of essence is an innovative re-interpretation, which he largely owes (...) to Avicenna, of the original Peripatetic doctrine. Nevertheless, it is shown that this re-interpretation is to be understood as a result of Avicenna’s and Aquinas’s effort to provide a consistent explanation of various statements in Aristotle’s writings, not always compatible with each other.

Review on Vaclav Nemec, Marius Victorinus: The Consubstantiality of The Trinity OIKOYMENH, Prague, 2006.

This paper deals with the political philosophy of Václav Havel, mainly its relation to ethics and what Michel Foucault called governmentality. Besides using his analytical framework, Foucault’s politics are engaged with to highlight similar trajectories of two intellectuals dealing with related dilemmas of ethics and politics. As a dissident of communist Czechoslovakia Havel, developed a profound critique of modernity, but also discovered technologies of the self, exclusive to dissidents, which empowered them in their moral struggle against the regime. The (...) Velvet Revolution in 1989 ascended Havel to the presidency of the republic, a position from which he quickly embraced and disseminated neoliberal governmentality. The final section deals with Havel’s use of human rights in the later years of his presidency, being a justification for military interventions and comparing them to Foucault’s conceptualisation of rights. Human rights discourse is the culmination of Havel’s lifelong quest for the ethical foundation of politics and it is the source of most difficulties and potentialities associated with this project.

An essential analysis of the modern science and technology that makes our twenty-first century lives possible--a scientist's investigation into what science really does, and does not, accomplish. We have never had so much information at our fingertips and yet most of us don't know how the world really works. This book explains seven of the most fundamental realities governing our survival and prosperity. From energy and food production, through our material world and its globalization, to risks, our environment and its (...) future, How the World Really Works offers a much-needed reality check--because before we can tackle problems effectively, we must understand the facts. In this ambitious and thought-provoking book we see, for example, that globalization isn't inevitable--the foolishness of allowing 70 per cent of the world's rubber gloves to be made in just one factory became glaringly obvious in 2020--and that our societies have been steadily increasing their dependence on fossil fuels, such that any promises of decarbonization by 2050 are a fairy tale. For example, each greenhouse-grown supermarket-bought tomato has the equivalent of five tablespoons of diesel embedded in its production, and we have no way of producing steel, cement or plastics at required scales without huge carbon emissions. Ultimately, Smil answers the most profound question of our age: are we irrevocably doomed or is a brighter utopia ahead? Compelling, data-rich and revisionist, this wonderfully broad, interdisciplinary guide finds faults with both extremes. Looking at the world through this quantitative lens reveals hidden truths that change the way we see our past, present and uncertain future. (shrink)

In the classical account of knowledge, S knows that P if and only if S believes that P, S is justified in believing that P, and P is true (JTB).. In 1963, Gettier presented two problems that casted doubt on this account. Since then, numerous authors proposed modifications or clarifications of JTB, however, these efforts have not produced a satis-factory solution. In this paper, the focus is on logical properties of justification. The Get-tier problem Case II is expressed in sentential (...) logic and Gettier Minimal Assumption (GMA) is introduced. It is shown that Gettier must have used GMA or some other as-sumption that entails GMA in his construction of Case II. Rejection of GMA solves Get-tier problem Case II and it is a step towards a better understanding of the logical proper-ties of justification and knowledge. (shrink)

ZusammenfassungDie Geschichte der genetischen Pränataldiagnostik ist bislang als Teil der Geschichte der Humangenetik und deren Neuorientierung als klinisch-laborwissenschaftliche Disziplin in der zweiten Hälfte des 20. Jahrhunderts betrachtet worden. Anhand neuen Quellenmaterials soll in diesem Beitrag gezeigt werden, dass das Interesse an der Pränataldiagnostik in Westdeutschland auch im Kontext von Forschungen entstand, die sich mit Gefahren für den Menschen in der Umwelt befassten. Anhand der Debatten um die Einrichtung des DFG-Schwerpunktprogramms „Pränatale Diagnostik genetischer Defekte“ 1970 untersuchen wir, wie die Technik der (...) Amniozentese in Westdeutschland von einer interdisziplinären Forschungsgruppe eingeführt wurde, die sich mit Schädigungen des Organismus durch Strahlen, Arzneimittel und andere Gebrauchsstoffe und Konsumgüter befasste. In einer als ökologische Wende bezeichneten Zeit wachsenden Umweltbewusstseins, so unsere These, sollte durch die Förderung der Pränataldiagnostik eine wahrgenommene Lücke in der Prävention umweltbedingt auftretender genetischer Anomalien geschlossen werden. Für die Pränataldiagnostik als „Schutzmaßnahme“ sprach unter anderem ihre erwartete Finanzierung als Krankenkassenleistung im Zuge der Reform des Abtreibungsrechts. Erst in einem zweiten Schritt führten Veränderungen von Strukturen der Forschung, vor allem aber Erfahrungen in der gynäkologischen Praxis zu einer Neuausrichtung auf die Diagnostik und Prävention mehrheitlich erblicher oder spontan auftretender Anomalien. Die Pränataldiagnostik, so wie sie schließlich in Westdeutschland ab den frühen 1980er Jahren routinemäßig Einsatz fand, hatte mit Fragen der „Umwelt“ kaum noch zu tun. Diese Fallstudie zur Frühgeschichte der genetischen Pränataldiagnostik handelt von dem noch wenig untersuchten Verhältnis von humangenetischer Forschung, klinischer Praxis und Umweltforschung und hat zum weiteren Ziel, den bisher in anderen Kontexten beschriebenen Wandel von Perspektiven in der Vorsorge um 1970 zu beleuchten.

Program comprehension is an essential part of software engineering. The paper describes the constructivist theory of comprehension, a process based on assimilation and accommodation of knowledge. Assimilation means that the new facts are either added to the existing knowledge or rejected. Accommodation means that the existing knowledge is reorganized in order to absorb new facts. These processes are illustrated by case studies of knowledge-level reengineering of a legacy program and of incremental change. In both cases, we constructed preliminary knowledge from (...) the program documentation, and then adjusted it by comprehending the actual code. The case studies supported constructivism as a suitable theory of program comprehension. (shrink)

Cílem tohoto příspěvku je interpretovat kolaboraci za druhé světové války jako fenomén. První část textu se zaměřuje především na její filozofické aspekty (pojmy mez, interakce a vina), a to hlavně na bázi Jasperse, ve druhé jsou aplikovány na český kontext druhé světové války a tranziční spravedlnosti. Vytvoří se tak schéma kolaborace, resp. kolaborace bude zasazena mezi další životní strategie. Díky tomuto propojení může příspěvek poskytnout interdisciplinární pohled na problematiku, která rozhodně vzhledem k současnému vývoji ve světě i v Evropě není (...) neaktuální. (shrink)

The essay is the critical reflection on the current state of global politics. It points to the importance of reconnecting politics with more substantial “human affairs”. The search for new understanding and conceptual tools is necessary on both sides of the political spectrum, however, the left should press for its lost identity more urgently. But what is even more urgent is the planetary vision based on reflexive rationality and a politics of dialogue, respect for the environment and civil society, overcoming (...) obsolete and pointless political strategies and forms of life. Knowledge and nature are to be taken as public assets. (shrink)

The present study addresses language ostracism in intercultural communication, a phenomenon when someone speaks a language but some members of this language community don’t speak to him in this language. This phenomenon is illustrated by language behaviour towards visually distinct bilingual minorities in Taiwan. Visually distinct minorities in Taiwan reported that they had been spoken to in English by small children or people who did not believe and accept that they really understood Mandarin when they spoke it. They might be (...) spoken to in English despite actually speaking good Mandarin. Taiwanese people behave this way because of two conditions existing in Taiwan: an English-speaking foreigner stereotype where people assume that every foreign-looking person speaks English, and English privilege in Taiwanese society which leads to people being treated better if they can speak English.

This study reviews the current information concerning the measurement of the situation awareness (SA) of the teleoperated drivers of remotely controlled cars. The teleoperated drivers who drive these cars are in a remote location, and they control the cars through a communication interface. The objective methods with probes are beneficial in measuring SA on a closed circuit without real traffic. Questions specifically should address the information provided on the road by haptic sensations, such as the slope of the road and (...) the vehicle's speed. Methods for measuring SA that involve probes and interruptions obviously are not suitable for use on public roads. A stable environment for the display and control of the communication interface is suitable for an eye tracker in measuring SA. These features also facilitate the use of subjective observer-rating methods. Both of these methods are suitable for driving on real roads because they are not intrusive. SA research in a real-road environment also should demonstrate how the SA of other drivers is affected by seeing a car without a driver. Given the remote character of driving, cultural differences in cognition may have a significant influence on the SA of the teleoperated driver. (shrink)

A review of Owen Hulatt´s Aesthetic and Artistic Autonomy.

This book examines the beginnings of the non-dual tantric philosophy of the famed Pratyabhija or ''Recognition'' School of tenth-century Kashmir. It includes a critical edition and annotated translation of chapters 1-3 of Somananda's Sivadrsti, the first Pratyabhija text ever composed, along with the corresponding passages of Utpaladeva's commentary, the Sivadrstivatti.

There is a popular idea that archaic humans commonly used wooden clubs as their weapons. This is not based on archaeological finds, which are minimal from the Pleistocene, but rather on a few ethnographic analogies and the association of these weapons with simple technology. This article presents the first quantitative cross-cultural analysis of the use of wooden clubs and throwing sticks for hunting and violence among foragers. Using a sample of 57 recent hunting-gathering societies from the Standard Cross-Cultural Sample, it (...) is shown that the majority used clubs for violence (86%) and/or hunting (74%). Whereas in hunting and fishing the club usually served only as a secondary tool, 33% of societies used the club as one of their main fighting weapons. The use of throwing sticks was less frequent among the societies surveyed (12% for violence, 14% for hunting). Based on these results and other evidence, it is argued that the use of clubs by early humans was highly probable, at least in the simplest form of a crude stick. The great variation in the forms and use of clubs and throwing sticks among recent hunter-gatherers, however, indicates that they are not standardized weapons and that similar variation may have existed in the past. Many such prehistoric weapons may therefore have been quite sophisticated, multifunctional, and carried strong symbolic meaning. (shrink)

An objective, comprehensive treatment of the world's energy situation assesses the major trends in energy consumption across the globe while examining the potential of wind, solar, hydroenergy, and biomass energy.

The topic of the article is the aporia of Bentham’s ethics. I point to the deeper philosophical foundations of Bentham’s ethical thought which draw on the materialist and empiricist traditions of the Enlightenment. I show how these foundations lead to a naturalistic reduction of all normative concepts, and I present the aporetic implications of this reduction with respect to the duality of Bentham’s basic ethical principle and his theory of the motivation of human action.

The most successful games today do not use a pay-for-product model, but involve complex and aggressive modes of monetizing their content (downloadable content, skins, in game currencies and markets, seasonal passes, etc.). While this has already been scrutinized, there are further consequences for games themselves and the economization of play. In my paper, I show how this strategy creates a conceptually novel situation, where playing can be considered to constitute reproductive labor-power and behavioral capital. In other words, playing here represents (...) not only consumption but also the very production of such consumption, insofar as the main reason behind the massive success of these games is precisely their massive pool of players and data concerning their activity. Firstly, I analyse PUBG: Battlegrounds as an example of the most successful model of monetizing games and maintaining a large number of players and interaction. I focus both on the economic incentives as well as on the gameplay that is generated or tailored towards aggressive monetization. Later, I set a theoretical context for my analysis stemming from ludocapitalist discourse (itself combining Marx with poststructuralism) and the concept of surveillance capitalism. I conclude my text with a systematization and definition of my original concept of behavioral capital and an attempt to formulate art critique and usage of games as a form of cultural production exposing several examples from contemporary art.

In this essay, it is argued that Abhinavagupta’s theory of error, the apūrṇakhyāti theory, synthesizes two distinguishable Pratyabhijñā treatments of error that were developed in three phases prior to him. The first theory was developed in two stages, initially by Somānanda in the Śivadṛṣṭi (ŚD) and subsequently by Utpaladeva in his Īśvarapratyabhijñākārikās (ĪPK) and his short autocommentary thereon, the Īśvarapratyabhijñāvṛtti (ĪPVṛ). This theory served to explain individual acts of misperception, and it was developed with the philosophy of the Buddhist epistemologists (...) in mind. In a third phase, Utpaladeva developed in his Śivadṛṣṭivṛtti (ŚDVṛ) a second theory of error, one that involved the noncognition of non-duality ( abhedākhyāti ) and served to explain both the appearance and perception of multiplicity, despite the strict monism to which all Pratyabhijñā authors subscribe. Abhinavagupta’s treatment of error, then, is significant not only because it was meant to explain all the various theories of error offered by opposing philosophical schools, as Rastogi has shown, but more importantly because it synthesized the thinking of his predecessors on the matter in a single, elegant account of error.

The present contribution discusses the dynamics of education (paideia) in Byzantium. As is well known, Byzantine education built on previous Greek/Roman educational traditions. We attempt to demonstrate, that while Byzantine education built on previous traditions, it transformed these traditions into a new specifically Byzantine ideal of paideia, which combined the content of previous hellenistic educational practices with a Christian outlook. But this Byzantine paideia was not merely a combination of the Greek and Christian tradition, but a new product. For the (...) first time, education was being regulated, since it was an important aspect of the ideological cohesivness of the state. Education was associated with morality and ethics. Perhaps due to Christian influence, especially from the ninth century, education became to be viewed as an „uplifting“ or anagogical force, which enabled one to arrive at a universalist perspective of life and the state.

The following article analysed the originality and creativity of Ethiopian Orthodox exegesis in a broader context of Byzantine and post-Byzantine Orthodox traditions. The originality of Ethiopian exegesis lies in its relative freedom from the conservative and traditionalist development of exegesis in other Eastern Orthodox contexts marked by the Graeco-Roman philosophical milieu. The Ethiopian exegetical tradition, being linked with traditional schooling, has managed to maintain a highly contextual and lively relationship with the community, with contemporary problems and issues and with other (...) traditions, while maintaining a relationship with its own historical background. Analysing the Ethiopian traditions in comparativist contexts is important, but some important questions need to be further asked as to ‘how’ and ‘why’ is an interpretation being produced, what is its exegetical premise and how exegetical imagination functions. Contribution: The article‘s input and contribution is manifold. As we have seen, a greater emphasis on the role and potential of the Ethiopian traditional ecclesial schools would facilitate their future preservation and function in a rapidly changing world with differing but often linear and exclusive developments in education. Furthermore, as discussed and demonstrated in the article, Ethiopian theological exegesis has a unique potential to contribute especially to contemporary Orthodox theology, which often struggles to maintain a balance between tradition and contextual or contemporary theology. The article further showed in this context that analysing exegetical traditions must also move beyond mere comparativist analysis and must include a broader study of the indeterminate or ‘mystical’ nature of interpretation which is intimately linked with the unpredictable or indeterminate dynamics of the world around us. Or in other words, how the exegete understands his or her freedom in interpretation. (shrink)
