Nature is an essay written by Ralph Waldo Emerson, published anonymously in 1836. It is in this essay that the foundation of transcendentalism is put forth, a belief system that espouses a non-traditional appreciation of nature. Transcendentalism suggests that divinity diffuses all nature, and speaks to the notion that we can only understand reality through studying nature. A visit to the Museum National d'Histoire Naturelle in Paris inspired a set of lectures delivered in Boston and subsequently the ideas leading to the publication of Nature. Ralph Waldo Emerson (May 25, 1803 - April 27, 1882) was an American essayist, lecturer, and poet, who led the Transcendentalist movement of the mid-19th century. He was seen as a champion of individualism and a prescient critic of the countervailing pressures of society, and he disseminated his thoughts through dozens of published essays and more than 1,500 public lectures across the United States.
