查询词典 sufficient condition

The reason included five aspects:①the effect of physical environment: the open geographical environment and barren soil urge the Greeks to look for development outward while the close geographical environment and advantaged condition for agriculture shaped the Chinese conservative thought and obstructed their steps of going out.②the advancing and blocking of the economic: the frequent trade offered an abundant living supply and open view while the self-sufficient agriculture with restraining trade rigidified the thought.③ the difference in politic institute and situation: the democracy polis of ancient Greece is exclusive in the ancient world. It shaped the atmosphere of freedom, democracy and adversary. While the monarchy in ancient China pursued the "united country" and shaped the atmosphere serving for politic and consolidating thoughts.④the guiding of traditional culture: the Greeks pursued freedom and wisdom and were curious about nature while the Chinese adored ancestor and obeyed the authority and prefer to pragmatism.

出现这种关系的原因本文从以下五点进行分析：①自然环境的影响：古希腊开放的地理环境和贫瘠的土壤种植条件促使古希腊人向外寻求发展，而古代中国封闭的地理环境和优越的农业环境阻碍了中华民族外出的脚步和开放的思维；②经济条件的推动与束缚：工商业发展的农业经济和自给自足的小农经济所创造的物质条件和对思维影响的差别是很大的；③政治制度和政治形势的差异：古希腊民主城邦制在古代世界是独树一帜的，它所营造的自由、民主的氛围和古代中国追求&大一统&的君主专制下为政治服务、思想趋向统一的氛围截然不同；④传统文化的引导：古希腊人在长期的城邦生活和参与海外贸易的生活中形成的开放、自由、对自然充满好奇、追求智慧等民族文化传统与中国保守崇古、讲究实用的文化传统形成了鲜明的对比；⑤思想家本身(来源：A58BC论文网www.abclunwen.com)目的不同：古希腊思想家为了变得智慧而获取知识，享受知识带来的乐趣，而古代中国思想家的一切动机都是为了&成化天下&、&以政裕民&服务。
