十九世纪中期,美国工业化快速发展。工业文明带来经济繁荣的同时,也给自然环境造成严重破坏;物质主义的泛滥给人们带来精神危机。不和现实妥协的梭罗走向瓦尔登湖,走向自然,开始自己的精神探索和生活实践。本文从梭罗的《瓦尔登湖》中概括其主要观点:自然是有生命的、人是自然的一部分、自然是人自我实现的途径。 In the mid-nineteenth century, the industrialization of the United States was rapidly developing. Industrial civilization has brought economic prosperity, but also caused serious damage to the natural environment; the proliferation of materialism has brought people a spiritual crisis. Thoreau, who does not compromise with reality, walks to Walden, goes to nature and begins his spiritual exploration and life practice. This paper summarizes the main viewpoints from Thoreau’s “Walden”: Nature is life, man is a part of nature and nature is the way for man to realize himself.
