Aëriae Animae: Souls and Elements from the Roman Cosmos to the Christian Afterworld
No full textIt has been widely recognized that until the fourth century AD Christians discussed freely about the source and the nature of the soul – the cases of Origen and Tertullian being emblematic of this situation in the East and in the West, respectively. It was only in the fourth century AD – after the so-called conversion of Constantine, with the Church’s increasing entanglement with political and social power and the emergence of a new generation of Platonizing intellectuals from the ranks of the upper class – that Christian bishops and theologians inaugurated a new discourse on the soul, its transcendent origin, immaterial constitution, and immortal destiny, which entailed the banishment and repression of earlier alternative visions. In the present paper, I shall be exploring an episode in this crucial historical transition, which, though limited in scope, can shed light upon the long-standing interactions between Greco-Roman theories of matter, elements, and principles, on the one hand, and Christian ideas of the soul and the afterworld, on the other. I am going to focus on the treatise On the City of God (De Civitate Dei) by Augustine of Hippo, who is usually regarded as one of the most decisive and influential figures in what can be called the Neoplatonic turn of fourth-century AD Christian eschatology. It is too often forgotten that throughout his long engagement with the issue of the nature and origin of the soul Augustine maintained an agnostic position, which is faithfully mirrored in all his writings. Indeed, I shall attempt to show that Augustine’s troubled reflection on the soul – on what he repeatedly terms as the ‘extremely obscure question of the soul’ (obscurissimam de anima quaestionem) – includes a meaningful dialogue with Book 16 of Varro’s Divine Antiquities (Antiquitates Rerum Divinarum) and its theory that the four elements of the cosmos host four different kinds of souls. I will investigate the philosophical pedigree of Varro’s cosmological-cum-psychological doctrine, with its recognizable mixture of Platonic and Stoic notions, arguing that Varro’s teacher, the Middle Platonist philosopher Antiochus of Ascalon, is its most likely source. However, far from restricting myself to an exercise in Quellenforschung, I shall claim that the Varronian theory reported in Book 7 of Augustine’s City of God should be read in light of Augustine’s sustained reception of the Platonic tradition in Book 8 of the same work, where the view that the body of demons is made up of air is endorsed by Augustine and attests to his serious pondering of the role of the natural elements in the emergence of a creature’s essence

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textVariations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
