Henry David Thoreau (see name pronunciation; July 12, 1817 - May 6, 1862) was an American author, poet, philosopher, abolitionist, naturalist, tax resister, development critic, surveyor, and historian. A leading transcendentalist,Thoreau is best known for his book Walden, a reflection upon simple living in natural surroundings, and his essay Resistance to Civil Government (also known as Civil Disobedience), an argument for disobedience to an unjust state. Thoreau's books, articles, essays, journals, and poetry total over 20 volumes. Among his lasting contributions are his writings on natural history and philosophy, where he anticipated the methods and findings of ecology and environmental history, two sources of modern-day environmentalism. His literary style interweaves close natural observation, personal experience, pointed rhetoric, symbolic meanings, and historical lore, while displaying a poetic sensibility, philosophical austerity, and "Yankee" love of practical detail.He was also deeply interested in the idea of survival in the face of hostile elements, historical change, and natural decay; at the same time he advocated abandoning waste and illusion in order to discover life's true essential needs.
