Walden (; first published as Walden; or, Life in the Woods) is an 1854 book by American transcendentalist writer Henry David Thoreau. The text is a reflection upon the author's simple living in natural surroundings. The work is part personal declaration of independence, social experiment, voyage of spiritual discovery, satire, and—to some degree—a manual for self-reliance.transcendentalism and social reform by Philip F.

Walden details Thoreau's experiences over the course of two years, two months, and two days in a cabin he built near Walden Pond amidst woodland owned by his friend and mentor Ralph Waldo Emerson, near Concord, Massachusetts.

Thoreau makes precise scientific observations of nature as well as metaphorical and poetic uses of natural phenomena. He identifies many plants and animals by both their popular and scientific names, records in detail the color and clarity of different bodies of water, precisely dates and describes the freezing and thawing of the pond, and recounts his experiments to measure the depth and shape of the bottom of the supposedly "bottomless" Walden Pond.

Background There has been much speculation as to why Thoreau went to live at the pond in the first place. E. B. White stated on this note, "Henry went forth to battle when he took to the woods, and Walden is the report of a man torn by two powerful and opposing drives—the desire to enjoy the world and the urge to set the world straight", while Leo Marx noted that Thoreau's stay at Walden Pond was an experiment based on his teacher Emerson's "method and of nature" and that it was a "report of an experiment in transcendental pastoralism".

Others have assumed Thoreau's intention during his time at Walden Pond was "to conduct an experiment: Could he survive, possibly even thrive, by stripping away all superfluous luxuries, living a plain, simple life in radically reduced conditions?" He thought of it as an experiment in "home economics". Although Thoreau went to Walden to escape what he considered "over-civilization", and in search of the "raw" and "savage delight" of the wilderness, he also spent considerable amounts of his time reading and writing. Thoreau was helped in his endeavour by regular domestic support from his mother, Cynthia, and his sisters, Helen and Sophia, during his time at Walden Pond. His mother and sisters frequently visited him or met him in town, bringing baskets of freshly baked goods, donuts, pies, and prepared meals, as the cabin was only about two miles from his family home in Concord. His mother routinely took his dirty laundry back to Concord to wash it, contrasting with the book's theme of absolute self-reliance.

Thoreau used his time at Walden Pond (July 4, 1845 – September 6, 1847) to write his first book, A Week on the Concord and Merrimack Rivers (1849). The experience later inspired Walden, in which Thoreau compresses the time into a single calendar year and uses passages of four seasons to symbolize human development.

By immersing himself in nature, Thoreau hoped to gain a more objective understanding of society through introspection. Simple living and self-sufficiency were Thoreau's other goals. The whole project was inspired by transcendentalist philosophy, a central theme of the American Romantic Period.

Organization

Part memoir and part spiritual quest, Walden opens with the announcement that Thoreau spent two years at Walden Pond living a simple life without support of any kind. Readers are reminded that at the time of publication, Thoreau has returned to living among the civilized. The book is separated into several chapters, each of which focuses on specific themes:

Economy: In this first and longest chapter, Thoreau outlines his project: a two-year, two-month, and two-day stay at a cozy, "tightly shingled and plastered", English-style 10 by 15 foot cottage in the woods near Walden Pond. He does this, he says, to illustrate the spiritual benefits of a simplified lifestyle. He easily supplies the four necessities of life (food, shelter, clothing, and fuel) with the help of family and friends, particularly his mother, his best friend, and Mr. and Mrs. Ralph Waldo Emerson. The latter provided Thoreau with a work exchange: he could build a small house and plant a garden if he cleared some land on the woodlot and did other chores while there. Thoreau meticulously records his expenditures and earnings, demonstrating his understanding of "economy", as he builds his house and buys and grows food.

The house's cost is and Thoreau gives "the details because very few are able to tell exactly what their houses cost and fewer still, if any, the separate cost of the various materials which compose them":

| Boards || || Mostly shanty boards. |- | Refuse shingles for roof and sides || |- | Laths || |- | Two second-hand windows with glass || |- | One thousand old brick || |- | Two casks of lime || || That was high. |- | Hair || || More than I needed. |- | Mantle-tree iron || |- | Nails || |- | Hinges and screws || |- | Latch || |- | Chalk || |- | Transportation || || I carried a good part on my back. |- | In all ||

Where I Lived, and What I Lived For: Thoreau recollects thoughts of places he stayed at before selecting Walden Pond, and quotes Roman philosopher Cato's advice "consider buying a farm very carefully before signing the papers".Thoreau, Henry David. Walden Civil Disobedience and Other Writings. W.W. Norton & Company, 2008, p. 61. His possibilities included a nearby Hollowell farm (where the "wife" unexpectedly decided she wanted to keep the farm). Thoreau takes to the woods dreaming of an existence free of obligations and full of leisure. He announces that he resides far from social relationships that mail represents (post office) and the majority of the chapter focuses on his thoughts while constructing and living in his new home at Walden.

Reading: Thoreau discusses the benefits of classical literature, preferably in the original Greek or Latin, and bemoans the lack of sophistication in Concord evident in the popularity of unsophisticated literature. He also loved to read books by world travelers.Christie, John Aldrich (1965). Thoreau as World Traveler. New York: Columbia University Press. He yearns for a time when each New England village will support "wise men" to educate and thereby ennoble the population.

Sounds: Thoreau encourages the reader to be "forever on the alert" and "looking always at what is to be seen". Although truth can be found in literature, it can also be found in nature. In addition to self-development, developing one's perception can also alleviate boredom. Rather than "look[ing] abroad for amusement, to society and the theatre", Thoreau's own life, including supposedly dull pastimes like housework, becomes a source of amusement that "never ceases to be novel". Likewise, he obtains pleasure in the sounds that fill his cabin: church bells ringing, carriages rattling and rumbling, cows lowing, whip-poor-wills singing, owls hooting, frogs croaking, and cockerels crowing. "All sound heard at the greatest possible distance," he contends "produces one and the same effect".

Solitude: Thoreau reflects on the feeling of solitude. He explains how loneliness can occur even amongst companions if one's heart is not open to them. Thoreau meditates on the pleasures of escaping society and the petty things that society entails (gossip, fights, etc.). He also reflects on his new companion, an old settler who arrives nearby and an old woman with great memory ("memory runs back farther than mythology").Thoreau, Henry David. Walden Civil Disobedience and Other Writings. W. W. Norton & Company, 2008, p. 96. Thoreau repeatedly reflects on the benefits of nature and of his deep communion with it and states that the only "medicine he needs is a draught of morning air".

Visitors: Thoreau talks about how he enjoys companionship (despite his love for solitude) and always leaves three chairs ready for visitors. The entire chapter focuses on the coming and going of visitors, and how he has more comers in Walden than he did in the city. He receives visits from those living or working nearby and gives special attention to a French Canadian born woodsman named Alec Thérien. Unlike Thoreau, Thérien cannot read or write and is described as leading an "animal life". He compares Thérien to Walden Pond itself. Thoreau then reflects on the women and children who seem to enjoy the pond more than men, and how men are limited because their lives are taken up.

The Bean-Field: Reflection on Thoreau's planting and his enjoyment of this new job/hobby. He touches upon the joys of his environment, the sights and sounds of nature, but also on the military sounds nearby. The rest of the chapter focuses on his earnings and his cultivation of crops (including how he spends just under fifteen dollars on this).

The Village: The chapter focuses on Thoreau's reflections on the journeys he takes several times a week to Concord, where he gathers the latest gossip and meets with townsmen. On one of his journeys into Concord, Thoreau is detained and jailed for his refusal to pay a poll tax to the "state that buys and sells men, women, and children, like cattle at the door of its senate-house".

The Ponds: In autumn, Thoreau discusses the countryside and writes down his observations about the geography of Walden Pond and its neighbors: Flint's Pond (or Sandy Pond), White Pond, and Goose Pond. Although Flint's Pond is the largest, Thoreau's favorites are Walden and White ponds, which he describes as lovelier than diamonds.

Baker Farm: While on an afternoon ramble in the woods, Thoreau gets caught in a rainstorm and takes shelter in the dirty, dismal hut of John Field, a penniless but hard-working Irish farmhand, and his wife and children. Thoreau urges Field to live a simple yet independent and fulfilling life in the woods, thereby freeing himself of employers and creditors. However, the Irishman will not give up his aspirations of luxury and the quest for the American dream.

Higher Laws: Thoreau discusses whether hunting wild animals and eating meat is necessary. He concludes that the primitive, carnal sensuality of humans drives them to kill and eat animals, and that a person who transcends this propensity is superior to those who cannot. (Thoreau eats fish and occasionally salt pork and woodchuck.) In addition to vegetarianism, he lauds chastity, work, and teetotalism. He also recognizes that Native Americans need to hunt and kill moose for survival in "The Maine Woods", and eats moose on a trip to Maine while he was living at Walden. Here is a list of the laws that he mentions:

One must love that of the wild just as much as one loves that of the good. What men already know instinctively is true humanity. The hunter is the greatest friend of the animal which is hunted. No human older than an adolescent would wantonly murder any creature which reveres its own life as much as the killer. If the day and the night make one joyful, one is successful. The highest form of self-restraint is when one can subsist not on other animals, but of plants and crops cultivated from the earth.

Brute Neighbors: This chapter is a simplified version of one of Thoreau's conversations with William Ellery Channing, who sometimes accompanied Thoreau on fishing trips when Channing had come up from Concord. The conversation is about a hermit (Thoreau) and a poet (Channing) and how the poet is absorbed in the clouds while the hermit is occupied with the more practical task of getting fish for dinner and how in the end, the poet regrets his failure to catch fish. The chapter also mentions Thoreau's interaction with a mouse that he lives with, a scene in which an ant battles a smaller ant, and his frequent encounters with cats.
