摘要
超验主义是美国文学史上的一个重要学派。梭罗深受其导师爱默生的影响，促进了超验主义的发展。不仅如此，作为19世纪超验主义的代表人物之一，梭罗实践了超验主义。《瓦尔登湖》作为一部超验主义的著作，其中有着梭罗的生活记录以及其对超验主义思想的实践过程。
尽管《瓦尔登湖》的作者生活在一个多世纪之前的美国，这本书永远都不会过时。《瓦尔登湖》赢得了越来越好的评价，尤其是它指引了我们如何在掌握了技术技能的时代里坚持爱护自然。在书中，梭罗通过自身经历证实人完全不用去破坏自然而是可以与自然和谐相处。这也是为何越来越多致力于环境保护的机构视梭罗作为先驱的原因所在。梭罗的《瓦尔登湖》不仅仅是在美国，更是在全球范围内都影响深刻。 梭罗《瓦尔登湖》中超验主义的实践英语论文:http://www.youerw.com/yingyu/lunwen_540.html
