Over the past thirty years, the disappearance, if not the death, of the intellectual in France has been the focus of significant conversation and debate. Yet a good bit earlier, two writers who epitomized that very figure of the intellectual, Jean-Paul Sartre and Albert Camus, in works written after their bitter break, seemed to have already sensed this decline. The present essay explores what Camus's novel La Chute [The fall] and Sartre's autobiography Les Mots [The words] share thematically and, in particular, how both works anticipate the fall of the French intellectual.  相似文献

We propose a reassessment of Neandertal mobility strategies by crossing technological and zooarchaeological data. A broad comparative approach to the Middle Paleolithic series from western France shows that the Levallois and laminar flaking systems, the Mousterian of Acheulian Tradition (MTA) shaping system and the Quina and discoidal-denticulate flaking systems, vary significantly in terms of duration of reduction sequences, blank versatility and tool maintenance. These technological systems, which prevail in this context over different time periods, reflect distinct mobility strategies as a response to differing hunting practices. This new approach to Middle Paleolithic technologies and related mobility patterns gives new insights into Mousterian diversity. It also highlights the determinant role played by large game hunting strategies in the organization of late Neandertal societies.  相似文献

Porcelain sauceboats excavated from a privy with a late 18th century (1786 or later) context at Independence National Historical Park (INHP) are anomalously Al-rich compared with previously analysed Anglo-American sulphurous phosphatic wares. Apart from their S content, they are most similar to phosphatic Wm Reid porcelain (Brownlow Hill, Liverpool, c. 1755–67, and its branch at Shelton, Staffordshire) in terms of their major element constituents, but they contain heavy minerals (e.g., TiO2 polymorphs) and in this regard resemble a dated (1773) silicious-aluminous-calcic (S-A-C) Bonnin and Morris porcelain (Philadelphia) openwork porcelain basket. In terms of morphology and composition, some TiO2 polymorphs in the 1773 basket match those from clay from White Clay Creek, Delaware, a resource reputedly exploited by Bonnin and Morris. Their high Nb/Cr ratios indicate derivation from a metapelitic (or granitic pegmatite) source. So too do some from the INHP sauceboats, although others are chrome-rich (∼1% Cr2O3), indicating a mafic source. The bedrock beneath White Clay Creek includes metasediments, granitic pegmatite, and metabasites (e.g., of the Wissahickon Formation), pointing to a local source for the TiO2 polymorphs in the porcelains described here. Although the evidence for a Bonnin and Morris provenance for the INHP sauceboats is circumstantial, their enrichment in heavy minerals, unusual – perhaps experimental – compositions, and aesthetic characteristics nonetheless suggest a Philadelphia origin for these artifacts. The compositions of 18th century Philadelphia porcelain support the contention that knowledge of phosphatic and S-A-C pastes originating in London was transferred first to Staffordshire and Liverpool, and then to Philadelphia, perhaps via a potter by the name of Wm Ball.  相似文献
