Poteries anciennes décorées à la roulette dans la Région des Grands Lacs

Résumé L'article propose une classification générale de la poterie ancienne décorée à la roulette, dans la Région des Grands Lacs et en Afrique de l'Est. Un premier groupe de poterie, appelé ici W, caractérisé principalement par la roulette torsadée, est produit vraisemblablement dèsca 800 AD; cette poterie pourrait avoir été diffusée de la région Est vers la zone interlacustre par le sud du Lac Victoria. L'hypothèse que le groupe W est associé à des populations de langues sud-nilotiques permet de reconsidérer les débuts du Deuxième Age du fer en Afrique interlacustre. Cet article suggère l'installation de groupes de pasteurs sud-nilotes dans la zone interlacustre; leurs rapports avec les autochtones sont examinés, en particulier le cas du Rwanda.Le groupe X (roulette nouée) apparaît en Ouganda dans les premiers siècles du second millénaire, suivi du groupe Y (roulette torsadée fine); à partir de 1500 AD, ils remplacent le groupe W dans la région interlacustre. Dans cet ensemble céramique, que l'on sait associé à des groupes de langues ouest-nilotiques venus du nord, une distinction est suggérée entre trois styles régionaux, qui sont mis en relation avec l'histoire des migrations de leurs producteurs.

This article offers a general classification of the ancient roulette-decorated pottery from the Great Lakes Region and from East Africa. A first pottery group, here named W, mainly characterised by twisted string roulette, appears as early asca 800 AD; this pottery might have been introduced to the interlacustrine area from the east and south of Lake Victoria. The hypothesis that the W group was associated with speakers of Southern-Nilotic languages is relevant to our view of the beginning of the Late Iron Age in interlacustrine Africa. This article suggests the establishment of pastoralist groups of Southern-Nilotic speakers in the interlacustrine zone and also examines their contacts with local populations, giving special attention to Rwanda.The X group (knotted string roulette) appears in Uganda in the first centuries of the second millennium, followed by the Y group (thin twisted string roulette). Fromca 1500 AD these groups replaced the W group in the interlacustrine area. In these last groups, which are associated with Western-Nilotes coming from the north, a distinction is made between three regional styles which are further correlated with the history of their makers.

     

Ordre des décrets divins,hiérarchie des droits humains

Until the xvi^th century, the use of public force in the service of religious unity seems to be a consequence of a zeal for the salvation of others. In order to reach civil peace, in the nations where different creeds confronted each other, it was necessary to find a theological foundation for the legal recognition of a freedom of conscience and of religion. The Protestant theologians of the Academy of Saumur, founded by Philippe Duplessis-Mornay, a negotiator of the Edict of Nantes, sought this foundation in a theology of creation. God created man to live peacefully in the company of his fellow-men and the drama of original sin, although it led for its reparation to a revelation from God, protected by the Church, did not destroy this primary order. «We are men, writes Amyraut, before being Christians.»     

Mobilité Universitaire et Circulation Internationale des Idées. Le Cas du Brésil Contemporain

In Brazil, considerable changes have affected the fields of social sciences and humanities. The growing number of advanced students studying abroad after the 1960s and later the creation of PhD programs have turned the road to national political power into an international one. As a result, academic fields have evolved and Elite formation has largely been transformed. Using these elements as a contextual framework, this article seeks to analyze the recent dynamics of the debate over the political and economic evolution of Brazil.     

Diversité des réactions réformées à la révocation

Starting from the analysis of the reactions of the Protestant groups to the Fontainebleau edict, this paper examines the development of two main concepts that are at the origin of political modernity, i.e. the distinction between religious and political domains on the one hand, and the popular sovereignty on the other. These two concepts emerged separately as a result of crossed and apparently paradoxal thoughts, whose coherence is to be sought in the anthropological positions underlying them. Therefore the study of the theological debates in the XVII^th century is a way by which the modern political concepts arose.     

Épistémologie, histoire et histoire des sciences dans les années 1930

During the 1930’s epistemology, history and history of science reciprocally and importantly influenced each other, even if indirectly. Philosophers and historians discussed the epistemological concepts emerging from the crisis of the exact sciences. They rejected Empirism and Idealism for an «experimental Rationalism» that connected theory and experience. It all caused a dialectical conception of science, fundamentally historical, but for which historians were still reluctant from a theoretical point of view. History was nevertheless the centre of philosophical and epistemological reflexions.     

Fédération et/ou confédération

A concern to pin ideological labels on Morris has obscured the continuing importance of romanticism and Protestantism for his socialist politics. Romanticism led him to seek self-realisation in an art based on naturalness and harmony, and Protestantism led him to do so in the everyday worlds of work and domestic life. From Ruskin, he took a sociology linking the quality of art to the extent of such self-realisation in daily life. Even after he turned to Marxism, he still defined his socialist vision in terms of good art produced and enjoyed within daily life. Moreover, his over-riding concern to promote a new spirit of art, not his dislike of Hyndman, led him to a purist politics, that is, to look with suspicion on almost all forms of political action.     

L’impossible constitution d’une théorie générale des machines ?

Three projects on the theories of machines are presented: “mecanology” of the architect Jacques Laffite (1932) inspired by biological evolution; “mecanical analysis ” of Louis Couffignal, a specialist in computing machines (1938), which pre figures functional analysis, and the algebraic theory of machines by the mathematician Jacques Riguet (beginning of the 1950’s). During those years, the three men are members of the Circle of Cybernetic Studies. The article focuses on the dialogue between projects, the axes of unification and divergence, and the styles, strategies and postulates of these three candidates, for generalization converging toward the reference constituted by cybernetics.     

The union Européenne des fédéralistes and its ‘third force’ programme

Environmental Education (EE) is broadly discussed in the Federal Republic of Germany. The different conceptions may be classified as the cognitive, the emotive, the cognitive-experiential and the system-critical model. In the article, the role of institutions in the educational system, dealing with EE, is described. Current activities in empirical research work and some findings on EE in German schools are reported.
