A philosophy pioneered by Ralph Waldo Emerson in the 1830's and 1840's, in which each person has direct communication with God and Nature, and there is no need for organized churches. It incorporated the ideas that mind goes beyond matter, intuition is valuable, that each soul is part of the Great Spirit, and each person is part of a reality where only the invisible is truly real. Promoted individualism, self-reliance, and freedom from social constraints, and emphasized emotions.
