I believe Emerson was an Illuminist or was exposed to Illuminati teaching. Will have to find the source for that connection another time.
Ralph Waldo Emerson
(May 25, 1803 – April 27, 1882)
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.
