The central distinguishing feature of Ernest Gellner's most important treatment of nationalism is the proposition that nationalism is necessary for industrial society. Relatively little attention has been paid to the philosophical dimension of this proposition. The question of necessity in social explanation, however, is a complicated philosophical problem and must be dealt with directly if this proposition is to be endorsed. I argue that Gellner's argument is philosophically flawed. The ‘ordinary prose’ of Nations and Nationalism fails to deliver what Gellner claims to have delivered: the demonstration of a necessary connection between nationalism and industrial society. This result is of particular relevance given Gellner's philosophical interests.  相似文献

An archaeological project and a community museum in Agua Blanca, Ecuador, have helped catalyse a remarkable process of ecological and cultural awareness complemented by economic advances. Some twenty-five years after the museum’s inauguration, as well as visiting the archaeological site and museum, tourists can observe the Machalilla National Park’s distinctive flora and fauna, camp, hike, swim, stay in village homes, buy locally made handcrafts, and eat in the community restaurant. These initiatives have been set up by the village in collaboration with local, national, and overseas agencies, in ways which spread benefits as widely as possible. After the introduction of a new constitution in 2008, which recognizes the multi-ethnic character of Ecuador’s population, Agua Blanca and adjacent communities asked to be officially recognized as ‘Pueblo Manta’ — an identity derived from the area’s pre-Spanish archaeology. Agua Blanca’s experience shows that much can be achieved through confidence in cultural identity, and that locally managed community tourism brings tangible economic benefits to local people, while serving to protect vulnerable archaeological sites from destruction.  相似文献

Waterfalls and rapids are a subject of study by scientists and scholars from a variety of academic and professional backgrounds. Unlike cave research, known as speleology, which also involves many different disciplines, the study of waterfalls is not generally regarded as a distinct branch of knowledge. Long neglected as subjects of research, waterfalls have received considerable attention since the 1980s. This paper traces the study of waterfalls from the late eighteenth century, a period when both a scientific and an aesthetic interest in landscape developed in Europe, to the present. The work of geographers, geologists and others who studied landforms and landscapes is examined, with particular attention to those who expressed a special interest in waterfalls, notably Alexander von Humboldt. The study argues that the scientific and aesthetic approaches to landscape research are not incompatible and supports the view that both are necessary for a full understanding and appreciation of the environment in which we live.  相似文献
