I dedicate this essay to the memory of the late Wolfgang Mommsen—the subject would have been congenial to him. It is one of a series of offshoots from a central project: a scholarly edition of Max Weber's Protestant Ethic with commentary. When I first told Prof. Mommsen of my plan in 1994 he looked me full in the face and gave a characteristic growl: “All that work!” Here was a man who knew what he was about. My thanks to Ross McKibbin and Keith Tribe for reading this paper in draft.

The article begins by examining Max Weber's relations with Lujo Brentano, much the most important “precursor” to Weber in the field of economics. In particular, Brentano conducted a form of parallel inquiry into the rise of ‘the spirit of capital’ in England 35 years before Weber looked for the origins of “spirit” of capitalism there, and the contrast between these two ideas casts much light both on Brentano and on Weber's Protestant Ethic. This personal history leads into a broader history of the transition in German economic thought between the 1860s – the formative decade for Brentano but also the era of Marx's Capital – and that of Weber's generation coming to maturity c.1890. Marx and Weber remain the two great canonical thinkers and original minds; but any authentic historical comparison between Marx and Weber must take in Brentano. The essence of the contrast between the generations is that between Weber's novel conception of an ethical ‘capitalism’, and the materialism and naturalism underpinning Brentano's and Marx's ‘capital’, although Weber and Brentano are alike as liberals, democrats and bourgeois.  相似文献

Domestic Pigs in Africa   总被引:1,自引:0,他引:1  
The history of African pig breeds is still controversial due to the relative scarcity of archaeological and genetic data clarifying their origins. While these breeds might descend from Near Eastern pigs entering the continent via Egypt during the Neolithic, Africa may be a primary domestication locus for pigs, as indicated for other species such as cattle and donkeys. In this regard, characterisation of the mitochondrial gene pool of African pig breeds has revealed a very low frequency of Near Eastern alleles, suggesting that, if Fertile Crescent pigs played a part in the foundation of African breeds, their genetic signature has been substantially erased. Interestingly, genetic analysis of western and eastern African pig breeds has revealed a strong phylogeographic pattern, with the latter harbouring Far Eastern alleles at high frequencies. This finding is consistent with data obtained for chickens and confirms that livestock was transported in ancient times, from the Far East to Africa as a consequence of the Indian Ocean trade. European colonisation of Africa also involved the introduction of exotic swine breeds such as Iberian pigs. The confluence of the highly divergent European and Far Eastern Sus scrofa gene pools contributed to significantly enrich the genetic reservoir of African swine breeds, favouring their adaptation to environmental conditions that are often harsh. Conservation of this genetic legacy will be of utmost importance to ensure the prosperity of current resource-based subsistence farming systems in Africa.  相似文献
