The acceptance of Newton’s ideas and Newtonianism in the early German Enlightenment is usually described as hesitant and slow. Two reasons help to explain this phenomenon. One is that those who might have adopted Newtonian arguments were critics of Wolffianism. These critics, however, drew on indigenous currents of thought, pre-dating the reception of Newton in Germany and independent of Newtonian science. The other reason is that the controversies between Wolffians and their critics focused on metaphysics. Newton’s reputation, however, was that of a mathematician, and one point, on which Wolffians and their opponents agreed, was that mathematics was of no use in the solution of metaphysical questions. The appeal to Newton as an authority in metaphysics, it was argued, was the fault of Newton’s over-zealous disciples in Britain, who tried to transform him from a mathematician into the author of a general philosophical system. It is often argued that the Berlin Academy after 1743 included a Newtonian group, but even there the reception of Newtonianism was selective. Philosophers such as Leonhard Euler were also reluctant to be labelled ‘Newtonians’, because this implied a dogmatic belief in Newton’s ideas. Only after the mid-eighteenth century is ‘Newtonianism’ increasingly accepted in the sense of a philosophical system.  相似文献

In the early eighteenth century Newtonianism became popular in the Netherlands both in academic (Boerhaave, ’sGravesande, Van Musschenbroek) and non-academic circles. The ‘Book of Nature’ was interpreted with the help of Newton’s natural philosophy and his ideas about a providential deity, thereby greatly enhancing the attractiveness of physico-theology in the eighteenth-century United Provinces. Like other Europeans the Dutch welcomed physico-theology as a strategic means in their battle against irreligion and atheism. Bernard Nieuwentijt, Johan Lulofs, Petrus Camper, and Johannes Florentius Martinet were prominent experts in the field. Combining Newtonian notions with Leibnizian optimism and romanticist trends, physico-theology remained popular in the Netherlands well into the nineteenth century.  相似文献

This article presents the main features of the work of Domenico Vandelli (1735–1816), an Italian-born man of science who lived a large part of his life in Portugal. Vandelli’s scientific interests as a naturalist paved the way to his activities as a reformer and adviser on economic and financial issues. The topics covered in his writings are similar to those discussed by Linnaeus, with whom Vandelli corresponded. They clearly reveal that the scientific preparation indispensable for a better knowledge of natural resources was also a fundamental condition for correctly addressing problems of efficiency in their economic allocation. The key argument put forward in this article is that the relationship between natural history and the agenda for economic reform and development deserves to be further analysed. It is indeed a central element in the emergence of political economy as an autonomous scientific discourse during the last decades of the eighteenth century.  相似文献

循环经济是针对持续的经济增长对资源和环境压力而提出的一种新的经济发展模式,也是一种新的技术经济模式。它遵循“资源——产品——再生资源”规律的一种自然和谐式经济发展模式。发达国家在循环经济理论和实践方面的探索均早于发展中国家,许多发达国家将建立循环型社会作为实现社会和经济协调发展的重要途径,对我国发展循环经济具有很强的借鉴意义。  相似文献

基于抗战、整理国故的需要,新启蒙运动开展起来。新启蒙运动是一场追求自由、理性的爱国运动,与五四运动相比更加强调理性,马克思主义在运动中占据了主动,有更加鲜明的政治倾向性,避免情绪化和片面性。新启蒙运动促进了抗日民族统一战线的进一步扩大,为马克思主义中国化做了准备。然而由于种种原因,新启蒙运动不幸早早结束。  相似文献
