Transcendentalism | Ralph Waldo Emmerson, Margaret Fuller, Henry David Thoreau
The formation of the movement was in 1836 with the establishment of the Transcendental Club of Boston, Massachusetts.
"Transcendentalism... maintains that man has ideas, that come not through the five senses, or the powers of reasoning, but are either the result of direct revelation from God, his immediate inspiration, or his immanent presence in the spiritual world," and "it asserts that man has something besides the body of flesh, a spiritual body, with senses to perceive what is true, and right and beautiful, and a natural love for these, as the body for its food."
... who opposed Unitarianism because it was based on the sensationalism of John Locke which "insisted that only that knowledge which could be demonstrated to the senses was valid." Emerson claimed this amounted to "'a cold intellectualism' that seemed to destroy the validity of man's conscience."
