It is always pretentious to treat African art as though a unitary vision of art as it is currently practiced in Africa were possible. This point of view in fact ignores or neglects African diversity: the individual plastic art experiments of African artists. These diversities, tied to the varied contexts and rapid changes that are steadily taking place everywhere, no longer permit such claims.

Na primeira parte da minha análise focarei no papel crucial que a linguagem, segundo Heidegger, desempenha no que diz respeito à questão se é possível salvar a humanidade e resgatar o ser do seu esquecimento total.Na segunda parte da minha apresentação, quero mostrar que a esperança depositada no poder transformacional da linguagem é um aspeto comum de um número considerável de filosofias do século passado, esgotando-se, no entanto, a atenção dada a este tema no início do século XXI. Há vários (...) sinais que dão a entender que o fazer tecnológico e/ou o regresso à imagem vão ocupando paulatinamente o lugar da instância ‘linguagem’ como topos à volta do qual se questionam os novos desafios societais.

Research and policy interest in questions of environmental waste is growing, especially plastic bag pollution. Where trash disposal and recycling are not highly regulated, the proliferation of plastic bags has created dramatic social and environmental consequences. In this article, we draw on 30 interviews with women who sell goods in markets in Mali as an entry point into investigating this issue through the interrelated dimensions of identity, gender, globalization, and the environment. We find the choices of women become suspect and (...) blamed for this environmental issue despite their having few socio-political options, while global and local political and economic elites have largely been responsible for implementing a series of policies and programs that have heightened the local effects of globalization while diminishing the services available to deal with the environmental and cultural dimensions of these changes. The issue of plastic bag pollution demonstrates the environmental consequences of development strategies that have emphasized economic growth with seemingly little concern or value for local cultures and environments, let alone the experiences and lives of poor women.

Aristotelian philosophy is generally regarded as incompatible with the mathematical methods and principles that form the basis of modern science. This book offers an entirely new perspective on this presumed incompatibility. It surveys the tradition of the Oxford Calculators from its beginnings in the fourteenth century until Leibniz and the philosophy of the seventeenth century and explores how the Calculators' techniques of quantification expanded the conceptual and methodological limits of Aristotelianism. In the process, it examines a large number of authors, (...) some of them never studied in this context. Exploring the relationship between various late medieval disciplines, the book sheds new light on the problem of continuity vs. discontinuity between scholasticism and modern science. Beyond its historiographical purpose, this book also hopes to be a source of inspiration for present-day philosophers of science. Co-edited by Daniel A. Di Liscia and Edith D. Sylla with the collaboration of Paul Bakker. (shrink)

The ArgumentOur understanding of the predisposing factors, the nature, and the fate of the Oxford Calculatory tradition can be significantly increased by seeing it in its social and institutional context. For instance, the use of intricate imaginary cases in Calculatory works becomes more understandable if we see the connection of these works to undergraduate logical disputations. Likewise, the demise of the Calculatory tradition is better understood in the light of subsequent efforts at educational reform.Unfortunately, too little evidence remains about the (...) Calculators and their context to enable anything like a full reconstruction of the relation of the Oxford Calculators' work to its context. Nevertheless, seeking out and fitting together the bits of information that do remain can add to our insight. Among the topics worth further research are the relation of training incalculationesto later careers in church or government, and the special features of the Calculatory tradition as a tradition consisting of multiple parallel manifestations closely interconnected with other disciplines, ranging from logic and natural philosophy to theology and medicine.

As its modern edition appears in the Synthese Historical Library, Adam Wodeham’s Tractatus de indivisibilibus does not appear to belong to any one discipline. With regard to its intended audience, the notice of the book appearing on the back cover states that “This book is an important contribution to the history of philosophy.” But it continues, “It will be of interest to all medievalists, particularly to those concerned with medieval science, philosophy, and logic. Theologians and historians of mathematics will also (...) find it useful.”Adam de Wodeham, Tractatus de indivisibilibus. A Critical Edition with Introduction, Translation, and Textual Notes, ed. Rega Wood (Dordrecht: Kluwer Academic Publishers, 1988). In its medieval context as well, Tractatus de indivisibilibus had ambiguous disciplinary status. It begins with the question, “Whether charity or [any] other incorruptible form is composed of indivisible forms.”Wodeham, Tractatus de indivisibilibus, p. 33. Such a reference to charity signals a connection to the Sentences of Peter Lombard, Book I, dist. 17. In introducing his answer to this question, however, Wodeham states, “Because this difficulty is the same for all composite divisible things, whether intensive or extensive, which are of one and the same species or homogeneous, therefore I will briefly inquire indifferently concerning the former and the latter.”Wodeham, Tractatus de indivisibilibus, pp. 34–35. Here and elsewhere, I occasionally modify Rega Wood’s translation in the interests of exactness. The solutions Wodeham then proposes to the questions he asks rely nearly always on logic. (shrink)

In this paper I aim to examine Heidegger’s analysis of existential spatiality in Being and Time in the light of Sloterdijk’s criticism of it. Sloterdijk states in Spheres I that Heidegger presented, in Being and Time, an “embryonically revolutionary” approach to being and space but did not complete it. His own ‘Spheres Project’ would purport fill this gap. Based on the analysis of the fundamental moments of existential spatiality (§§12 to 28 and §70 of Being and Time), and taking into (...) account comments made by Heidegger himself in later years, I will attempt to answer the question of the alleged unfinished character of the analysis of existential spatiality in Being and Time.

In his De primo et ultimo instanti, Walter Burley paid careful attention to continuity, assuming that continua included and were limited by indivisibles such as instants, points, ubi, degrees of quality, or mutata esse. In his Tractatus primus, Burley applied the logic of first and last instants to reach novel conclusions about qualities and qualitative change. At the end of his Quaestiones in libros Physicorum Aristotelis, William of Ockham used long passages from Burley’s Tractatus primus, sometimes agreeing with Burley and (...) sometimes disagreeing. How may this interaction between Burley and Ockham be understood within its historical context? (shrink)

Reading Cassirer’s philosophy of myth: early signs of Heidegger’s late philosophy? In 1928, Heidegger’s book review of the second volume of Cassirer’s Philosophy of Symbolic Forms (The Mythical Thought) was published in the Deutsche Literaturzeitung. Cassirer’s text date of 1925, hence it is possible that Heidegger had read it even before the publication of Being and Time. What makes both texts worthy of a closer examination is the fact that several central motifs and terms of Heidegger’s later philosophy are already (...) present in these two texts. Heidegger focuses particularly on Cassirer’s reflections on the representation of mana (Mana-Vorstellung) in mythical thinking. This representation involves not only the distinction between the familiar and the unfamiliar, the ‘uncanniness’ or ‘not-at-homeness’ that befalls mightily the Dasein, but also the distinction between the sacred and the profane and that of the four world regions (Weltgegenden) and its organization in form of a cross. Although not everything that Heidegger announces is interpretable as full awareness of the future impact of these traces, one would wonder if the density with which they appear would be mere accident. Thus, the article contributes to the debate on the issue of the emerging of Heidegger’s late thought and its origins which can be traced back to the stage of genesis, or rather, the final draft of Being and Time.

In a long question, "Whether there is motion to quality," which became part of his Oxford Expositio omnium librorum Physicorum cum questionibus optime disputatis, composed before 1310, Walter Burley supported the succession-of-forms theory of qualitative change. After commenting on Peter Lombard's Sentences at Paris, Burley took part in disputations on controversial questions in the early 1320s, resulting in his De primo et ultimo instanti and his Tractatus Primus and Tractatus Secundus de intensione et remissione formarum. In these independent controversial works, (...) Burley advanced and defended the succession-of-forms theory with greater detail and precision. This paper examines the treatment of the mathematics of alteration in Burley's final Parisian Expositio in libros octo de physico auditu in light of this earlier controversial work. (shrink)

Money performs its economic functions best when its value remains stable over time. This Article explores how that desideratum was achieved, or not achieved, under five identifiable monetary regimes in economic history. Transitions from one regime to another resulted from the demands of economic growth, which some regimes met better than others. The modern fiat money regime is optimal in most economic respects. Whatever amount of money needed to accommodate growth can be supplied at minimal costs. But political control over (...) money creation can be used to increase the short-term control over economic resources of those in power and their constituents. When such debasements of money have occurred, the political economy of every regime interfered with achieving optimal long-term economic outcomes by unleashing inflation. How might the modern fiat money regime avoid that result? (shrink)
