Henry David Thoreau 
Walden 

Henry David Thoreau, American transcendentalist writer and philosopher. In the spring of 1845, he built a log cabin in the Walden lakeside woods of his hometown Concord city. From then on he worked with sunrise — tilling and writing at sunset. In 1847, the first draft of Walden was completed, and after five years of repeated revisions, additions and embellishments, it was finally presented to the world as the immortal Walden, or Linden Chronicle. In the book, the author describes in detail his two years and two months in Walden lakeside forest and his many thoughts during that time. He called the experience an attempt of simple life. Based on his deeply transcendentalist views, the author gives an excellent account of the seasons and spiritual revival in nature. This book starts with spring, goes through summer, autumn and winter, and ends with spring, which is exactly the cycle of life. The end is also the starting point, and life begins to recover. In the book, the author talks about everything from the past to the present, extolling natural beauty and lambasting social problems. Generations of readers have been awed by the subtlety of its prose and the depth of its anatomy, and it deserves its reputation as one of the most popular nonfiction works in 19th-century American literature.
