In this essay I will argue that Platonic myths are a useful tool not only in the education of the ignorant but for the philosophical mind as well. To do this I will first examine the limitations and problems that Plato sees in written communication, and I will then argue that myths avoid these problems by undermining their own validity. If they are to avoid the problems that plague the written format, myths must show themselves for what they are: inadequate tools for giving a complete account of a particular subject. Myths, I will argue, are those shadows (to use the term from the story of the Cave in the Republic) that show their own shadow-like nature. In this way the myth is able to work hand-in-hand with dialectic to educate philosophers.  相似文献

The archaeology of the Late Postclassic lowland Maya (ca. A.D. 1200–1517) is summarized and reviewed. The history of past research is outlined, and investigations on topics of major scholarly concern are discussed. The current data allow us to present an approximate reconstruction of the events and processes that characterize the period, although the information on many areas and topics is still fragmentary. Research in Maya archaeology has focused heavily on the more spectacular developments of earlier periods, creating the impression that the last few centuries of the prehispanic era were a time of disorganization and decline. New data and interpretations indicate that the Late Postclassic was a dynamic period in which the lowland Maya were moving in new directions, restructuring their society and worldview.  相似文献

Several geoarchaeological techniques have been employed in evaluating an open-air site within a uniform sand matrix, near Rio Maior, Portugal. Electrical resistivity data, acquired at the Upper Palaeolithic site complex of Cabeço do Porto Marinho (CPM), delineated an important new occupational locus. This result was confirmed, first by auger testing which recovered subsurface artefacts, and then by direct excavation. In addition, 107 samples were recovered at the site for magnetic susceptibility measurements. Comparisons between magnetic susceptibility profiles from two loci, including the new area at CPM, show distinctive patterns which allow direct correlation between the occupation areas. These methods provide quick and inexpensive means for investigators to evaluate new sites or to correlate between and within sites, without resorting to other more time-consuming and expensive techniques.  相似文献

The assessment of fetal age at death is fraught with many complications and often the determination of the maturity of the fetus is a more realistic solution to the question of fetal viability. This study examines the pattern of appearance of primary centres of ossification in the fetal hand and foot, in an attempt to construct a maturity continuum. The results show that completion of ossification in the hand precedes that in the foot and generally occurs in a more regular pattern. The method proves useful at assessing fetal maturity between the third and tenth months of intra-uterine life. In addition, the relationship to other major centres of ossification is considered.  相似文献
