Nature is an essay written by Ralph Waldo Emerson, and published by James Munroe and Company in 1836. In the essay Emerson put forth the foundation of transcendentalism, a belief system that espouses a non-traditional appreciation of nature. Transcendentalism suggests that the divine, or God, suffuses nature, and suggests that reality can be understood by studying nature.

Ralph Waldo Emerson was an American essayist, lecturer, philosopher, 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.
