The non-religious movement that loved nature and favored a simple life is known as Transcendentalism. Transcendentalism was a philosophical and literary movement that emerged in the 19th century, primarily in the United States. It emphasized the inherent goodness of people and nature, the importance of self-reliance, individual intuition, and a connection to the divine through nature. Prominent figures associated with Transcendentalism include Ralph Waldo Emerson and Henry David Thoreau. They believed in the spiritual and moral value of nature and advocated for a simpler, more contemplative way of life in harmony with the natural world.
