Many critics have suggested that there is no clear distinction between realism and its related late nineteenth-century movement, naturalism.

Transcendentalism was a philosophical movement that developed in the late 1820s and 1830s in the eastern region of the United States. The movement was a reaction to, or protest against the general state of intellectualism and spirituality.n the 19th century, under the influence of Ralph Waldo Emerson (who had been a Unitarian minister) and other transcendentalists, Unitarianism began its long journey from liberal Protestantism to its present more pluralist form. Transcendentalism also influenced Hinduism.
