Thoreau loves and returns to nature. His viewing"man as part and parcel of nature"echoes Daoism's"identification of the self with nature"; Thoreau's stressing a simple life style is identified with Daoist's returning to simplicity; water is frequently cited in Walden as an image, which strikingly resembles some chapters of Tao Te Ching. Thoreau repeatedly emphasizes the significance of medication in quietude, which is also expressed in Tao Te Ching. These are but a few examples to show striking similarities between thoughts reflected in Walden and those preached by Daoism. The book Walden is a manifest demonstration of Daoism. This writing intends to take a minute and comparative look at Daoism elements embodied in Walden. 展开更多

Henry David Thoreau(1817-1862) was an American writer, philosopher, poet, abolitionist, tax resister, development critic, historian, leading transcendentalist, and abolitionist. His name is almost means nature because he has devoted his entire life into observing and studying nature and written many literary works recording his ideas on man-nature relationship. Rereading his works now helps us to deal with the urgent and serious natural crisis. 展开更多

Zhuangzi is the masterpiece of Zhuangzi, and Walden is the masterpiece of Henry David Thoreau. This paper intends to study the similarities of Zhuangzi's and Thoreau's outlooks on life by analyzing Thoreau's origin with Taoism and the absorption from Taoism in Walden. By making a large amount of analysis and comparison of the texts in these two works, the paper comes to such a conclusion: both Thoreau and Zhuangzi advocate to simplify people's material life and to seek voluntary poverty; they are willing to enjoy the solitude and pursue the spiritual independence and freedom; they prefer to return to nature, live harmoniously with nature and therefore reach the realm of"unity of heaven and humanity". They pay more attention to human existence and their spiritual state. In the complicated modern society, people devote themselves to seeking a materially rich life. However, they do not attach enough importance to spiritual richness. As a result, the whole human society is facing a serious spiritual crisis in modern times. Thoreau's and Zhuangzi's outlooks on life can lead people to go through various difficulties of life and guard the pure land of the heart. 展开更多

As a very significant part of Thoreau's Walden, nature can never escape the discussion or any other critical analysiswhenever and wherever this book is concerned. Nature for modern people is usually in opposition to human civilization, while Tho-reau regards it as a whole that integrates wilderness and the world erected by human kind. By probing into the relationship betweenwild nature and human world as is discussed in Walden, this paper discovers that Thoreau intends human beings to enter nature notonly to learn from it, but also to return to themselves with the knowledge given by nature, and then finally to go inward. 展开更多

Walden is composed by Henry David Thoreau who is an illustrious and influential American nature writer and an embodiment of American Transcendentalism. It is a household classic and has been a masterpiece in the American literature and world literature. In the contemporary epoch, investigation into the canonization of Walden can be dynamic, progressive and longlasting. This treatise intends to furnish an all-round scholarship on the canonization of Walden from two perspectives: recognizance of Walden in America, development of literature theory. 展开更多

However, he did not attract much attention at that time. In fact, Thoreau did not have a profound influence on American culture until the 20th century. It is generally acknowledged that his masterpiece Walden is one of the most outstanding literary works, in which the richness of thoughts contributes greatly to the spread of Thoreau's philosophy. Thanks to it, Thoreau's philosophy has attracted more and more attention. It is pleasantly surprised for a Chinese reader to find Confucianism in an American classical work of the 19th century. Many scholars have studied Confucianism in Walden in order to analyze how Confucianism influences Thoreau. However, these studies more or less overstate or understate the influence of Confucianism. Therefore, such a research does have great practical significance, that is, to objectively analyze how Confucianism influences an American writer and how it is repre?sented in his representative work. 展开更多

With the advent of globalization,there is an increasing number of foreign literary works have entered the field of vision of Chinese readers.Walden,Henry David Thoreau’s collection of classical essays,is popular because of its abundant content,profound significance,intelligent expression and unique views on life.From the perspective of Skopos theory,this paper closely combines translation theory with translation practice,taking the Chinese translation of Walden as an example,aiming at its linguistic characteristics,to provide some suggestions and solutions for its Chinese translation.There are many articles studying literary translation from the perspective of Skopos theory,but the combination of Chinese translation of Walden lake and Skopos theory is rare,so the study of this paper has certain practical significance. 展开更多

With the deterioration of the environment and the unbalanced relationship between man and nature,people are plagued by varieties of social problems and rising spiritual crises.This paper aims to analyze Thoreau’s characters in Walden and attempts to provide the implications for our contemporary life.Combined with Thoreau’s life experience and the background of Walden,the paper starts with the analysis of Thoreau’s characters from three aspects concerning his pursuit of inner serenity,search for true essence of life and abiding passion for life,which constitute his unique and independent characters and provide the enlightenment for contemporary life.We concluded that unique thoughts,attitudes,and spirit embedded in Thoreau’s characters are inextricably connected with our contemporary life.His personal experience and practice of solitary life at Walden Pond is a testimony to the necessity of closing to nature actively and confronting life passionately. 展开更多
