In the early spring of 1845, Henry David Thoreau built and lived in a cabin near the shore of Walden Pond in rural Massachusetts. For the next two years, he enacted his own Transcendentalist experiment, living a simple life based on self-reliance, individualism, and harmony with nature. The journal he kept at that time evolved into his masterwork, Walden, an eloquent expression of a uniquely American philosophy.

This essay by Thoreau first published in 1849, argues that individuals should not permit governments to overrule their consciences. It goes on to say that individuals have a duty to avoid allowing the government to make them the agents of injustice. The quote: "That government is best which governs least," sometimes attributed to Thomas Jefferson or Thomas Paine, actually was first found in this essay. Thoreaus' thoughts were motivated by his disgust with slavery and the Mexican-American War but they are still relevant and resonate today.

In 1845 Henry David Thoreau, one of the principal New England Transcendentalists, left the small town of Concord for the country. Beside the lake of Walden he built himself a log cabin and returned to nature, to observe and reflect – while surviving on eight dollars a year. From this experience emerged Walden, one of the great classics of American literature.

Thoreau gives an account of three canoe and hiking journeys - by himself and with others - through the mostly uninhabited forests of Maine in the 1850s. Identifying birds, trees and plants by their botanical as well as their common names, he also records the Indian names of lakes, rivers and plants. He investigates the connections between waterways and trails, and provides detail on camping, fishing and hunting in the woods, using whatever is at hand. Extolling the beauty of the wilds that he encounters, Thorough’s narrative is also imbued with elements of his philosophy.

Thoreau's classic account of the solitary life, describing his attempts to simplify his life and sort out his priorities by living alone in a cabin beside Walden Pond for nearly two years, is one of the most influential books ever written. The bible of the environmental movement, Walden vividly portrays Thoreau's reverence for nature, and his understanding of the idea that nature is made up of crucially interrelated parts.

The Transcendentalists and Their World offers a fresh view of the thinkers whose outsized impact on philosophy and literature would spread from tiny Concord to all corners of the earth. Ralph Waldo Emerson, Henry David Thoreau, Nathaniel Hawthorne, and the Alcotts called this New England town home, and Thoreau drew on its life extensively in his classic Walden. Concord was a community in ferment, whose small, ordered society was unsettled through the expansive forces of capitalism and democracy.

Gondolin, beautiful but undiscoverable, is central to the enmity of two of the greatest powers in the world.

John Muir, who was born in Scotland and emigrated to America in 1849, was an advocate of U.S. forest conservation and was largely responsible for the establishment of Sequoia and Yosemite national parks in California. Muir has emerged as perhaps the greatest prophet of an era which finds itself suddenly aware of the urgent need to care for our planet.

In June 1867, Mark Twain set out for Europe and the Holy Land on the paddle steamer Quaker City. His enduring, no-nonsense guide for the first-time traveler also served as an antidote to the insufferably romantic travel books of the period.
