Walden or, "Life in the Woods", is, primarily, a reflection upon simple living in natural surroundings. Henry David Thoreau kept a journal during his stay in a cabin beside Walden Pond in Concord, Massachusetts, for two years, two months, and two days, from July 1845 to Sept 1847. The book is based on that journal. In addition to being a beautiful tribute to the joys of a simple life, to Nature, the seasons, and the animals in the area, this is a profound work dealing with the illusions permeating civilized society and the real meaning and purpose of life. Critics today regard Walden as a classic that explores natural simplicity, harmony, and beauty as models for just social and cultural conditions.
