Karl Jaspers famously characterized the period from the beginning of the eighth to the end of the third century before Christ as an “Axial Age” in which intellectual freedom and creativity blossomed as never before. This article argues that it was followed, five hundred years later, by an “Anti-Axial Age”, which devised a novel formula for intellectual and political repression. Its essence was the state’s capture of the millenial narrative, which had first been developed as religious doctrine within Zoroastrianism and Christianity. Involving the two great classical empires of Western Eurasia, Persia and Rome, and then empowering the expansion of Islam, the Anti-Axial Age left an ideological legacy that continues to haunt the contemporary world.  相似文献

In the post-Soviet economic environment, new opportunities arose attendant with market reform. Rural households had to choose whether to continue past behaviors – to subsist – or to adapt, the latter requiring a degree of risk. This paper analyzes risk-averse and risk-taking households by addressing three main questions: (a) which households are risk-averse and which are risk-takers?; (b) what are the characteristics of those different types of households?; and (c) which factors have greatest causal properties in explaining household risk-taking? Typologies of risk-averse and risk-taking households are presented. Using survey data, statistical analysis disaggregates peasant households, showing that households with higher total income are more likely to take on risk. Land expansion is important mainly for commercially oriented households.  相似文献

Smallholdings in the rural areas of northwest Syria are a result of land fragmentation that is due to inheritance. Because of rapid population growth combined with land fragmentation, these smallholdings are increasing and cannot sustain the rural households whose sizes and needs are also increasing rapidly This situation has led to increasing numbers of males migrating to urban areas in Syria and to neighbouring countries looking for work opportunities. In addition, recent agricultural intensification trends seem to have led to the emergence of a waged labour force which, in the absence of male workers owing to significant rates of migration, is now predominantly female. Agricultural labour use depends upon household characteristics and resources (type of labour used, gender of labour waged/exchanged/familial). The article attempts to present a comprehensive analysis of household labour use in distinctive farming systems in one region of Syria that has undergone great change in recent decades, and examines the changes in the composition of the agricultural labour force. Secondary information, rapid ural appraisals and formal farm surveys were used to gather information on the households in a study area where different farming systems coexist. The results show that the decrease in landholding size, the resulting male migration, and land intensification have resulted in the expansion offemale labour in agriculturalproduction, which has been termed in this research a 'feminization of agricultural labour'. This suggests that agricultural research and extension services will have to work more with women farmers and farm workers, seek their wisdom and involve them in technology and transfer. This is not easy in conservative societies but requires research and extension institutions to take this reality into consideration in their programmes.  相似文献
