‘Walden is, in fact, a vast rebirth, the purest and most complete in American literature. It is the ideal companion for those who, like Thoreau, are frustrated by the noise and strife of modern life. It provides hope of an inviolable sanctuary from worldly encroachments. Leo Marz called Walden an ‘American pastoral’ and compared Thoreau’s beanfield with Virgil’s landscape–a place sheltered from the demands of civilization. Walden Pond was to Thoreau what a swinging birch tree was to Robert Frost–a temporary escape from the world. Walden is also therapeutic for both the writer and the reader. It is a record of Thoreau’s intimacy with nature after his frustrations elsewhere, an expression of the pent-up feelings and ideas arising from his experiences in society and nature. His unrestrained and fiery temperament was calmed by the serenity and love that nature can offer. Walden ‘remained as tonic as sassafras tea in the spring of the year is supposed to be.’ – Frank Davidson
