Abstract: The famous German realist writer Fontanes Der Stechlin is a novel dealing with issues of tradition and modernity, new and old. This novel consciously highlights the contrast between the conservative aristocracy and the openminded aristocracy through subtly conceived spatial construction, and the author conveys his own attitude through comicstyle characterization of the former, that is, the aristocracy coming from the traditional society should be open and calm in the face of social development and changes of the times, given the unstoppable trend of the history. On the other hand, tradition and modernity, nature and industry are organically intertwined, both in the countryside of Stechlin and in the metropolis of Berlin. Tradition should accept advancement within the tolerable range and new things replace tradition only when necessary. The correct attitude towards historical development lies in the golden mean of harmonious coexistence of old and new things.

摘要： 德国著名现实主义作家冯塔纳的最后一部长篇小说《施泰希林》是一部探讨传统与现代、新与旧问题的时代小说。小说通过构思巧妙的空间构建，有意突出保守贵族与开明贵族之间形成的反差，并通过对前者的漫画式戏谑勾勒传达作家本人的立场态度，即在时代潮流不可阻挡的前提下，从传统社会一路走来的贵族阶层应该抱持开放、从容的态度面对社会发展与时代变化。与此同时，无论在乡下施泰希林还是在都市柏林，传统与现代、自然与工业都已实现有机地相互交融。传统在可承受的范围内接纳先进，新兴事物只在必要情况下才去代替传统。面对历史发展的正确态度在于新旧事物和谐并存的中庸之道。
