Summary This paper is a short survey of five Mmms authors - in chronological order, abara, Kumrila, Prabhkara, likantha, Prthsrathi Mira - in reference to the right (adhikra) of learning by heart the Veda (adhyayana). More or less explicitly, they dismiss it for the social class of the dra, and their gloss on the first stra of the dra is highlighted with the help of this view. The paper summarizes also a number of points raised by this complicated stra.  相似文献

The Iron Age settlements of northern Cameroon were dispersed across the landscape, taking advantage of different eco-climatic zones to exploit a variety of natural resources. Situated at the interface of the upper and lower terraces of the Benue River, mound sites in the area around Garoua have occupation histories spanning multiple centuries. The site of Langui-Tchéboua displays evidence for rapid accumulation of sediments approximately 700 years ago, which may have been a deliberate construction strategy that would have allowed the site’s inhabitants to exploit resources in both floodplain and dryland contexts. The combined use of multiple dating methods and micromorphology provide novel insights into both the mechanisms of anthropogenic landscape change and possible motivations governing those choices.  相似文献

It has come to be increasingly recognized that The Prince fails to offer a viable and practical guide to successful political action. Violent force provides Machiavelli's theory with the only even tentative form of purposive action he can theoretically sustain. In violence, elements of the action itself seem to appear as consequences, thus restoring a semblance of connection between deliberate action and outcomes. As a result, successful political action becomes less a question of examples and precepts than a matter of improvisational daring, a kind of action that arises directly from the immediate situation itself. In this connection, Machiavelli's representation of Cesare Borgia serves as an inspirational example of the improvisatory prince. In the final analysis, action per se emerges as the only rival to fortuna. Impetuosity replaces skill and wisdom, meeting the capriciousness of fortuna with a form of action equally riotous. This seems less discouraging from the perspective of the theory once we recognize that Machiavelli's point of view has shifted from that of an imagined individual prince to the interests of the political field of action itself. From there, it is action itself that sustains the possibility of politics.  相似文献

Evidence for bitumen use in Middle Palaeolithic sites is an exception in Pleistocene archaeology. This paper presents the discovery of three tar-bearing Levallois artefacts found in the Mousterian sequence in Hummal (Central Syria). The organic residues were submitted to geochemical study. Gas chromatography–mass spectrometry analyses of saturated and aromatic hydrocarbons and isotopic data show the presence of bitumen. The most likely location of natural asphalt provisioning is the Shaaf outcrop in the Bichri desert. The bitumen-bearing stone tools add further important data to the growing knowledge about bitumen processing in the Middle Palaeolithic spring sites of El Kowm. Identification of the provisioning place for natural asphalt enables a more precise assumption about the site's catchment area. From a technological point of view, the tar-bearing specimens provide information on the range of tool forms selected for hafting. Ballistic features arguably indicate that the pointed Levallois blanks seem to be spear points that were fitted to a wooden handle. In at least one case, this technical procedure was seemingly executed during a brief episode of occupation and replacement of worn out implements. This small, bracketed window of detailed insight into Mousterian technology is linked with the more general relationship between Levallois technology and stone tool hafting.  相似文献

Ce travail porte sur I'extension géographique des orts-teins au Québec et vise à déterminer les causes de leur répartition principalement pour la Côte-Nord du Saint-Laurent. Les données ont été puisées en partie dans des rapports pédologiques publiés sur le Québec, mais aussi observées dans des sites d'échantillonnage sur la Côte-Nord du Saint-Laurent, l'île d'Anticosti et en Gaspésie. Par ailleurs, pour les datations au 14C, six sites d'echantillonnage ont été choisis sur la Côte-Nord. Les résultats indiquent que les ortsteins se développent sous toutes les latitudes au sud de 55e parallèle et sous différentes conditions physiographiques et géologiques. On les retrouve aussi bien sur des silts sableux que sur des graviers grossiers et leur présence est favorisée lorsqu'il y a fluctuation de la nappe d'eau. Les datations au 14C ont donné des âges relativement jeunes pour les ortsteins, soit moins de 420 ans bp, indiquant qu'il y a une migration active de la matière organique dans les horizons concrétionnés. The present paper concerns the geographic delimitation of ortsteins in Québec and deals with the causes of their distribution mainly for the North Shore of the St. Lawrence River. Data was gathered in part in published geological reports in Quebec, and also acquired in the field along the North Shore of the St. Lawrence River, Anticosti Island, and in the Gaspé Peninsula. Furthermore, six study sites were selected for dating by 14C along the North Shore. Results indicate the ortsteins develop under all latitudes south of the 55th parallel and under different physiographic and geological conditions. They can be found on both sandy silts and coarse gravels, and their presence is enhanced whenever the water level fluctuates. 14C datings give relatively young ages for ortsteins, less than 420 years BP, indicating that an active migration of organic matter occurred in the indurated horizons.  相似文献
