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.

Within this essay, Emerson divides nature into four usages; Commodity, Beauty, Language and Discipline. These distinctions define the ways by which humans use nature for their basic needs, their desire for delight, their communication with one another and their understanding of the world.
