<P> Transcendentalism influenced the growing movement of "Mental Sciences" of the mid-19th century, which would later become known as the New Thought movement . New Thought considers Emerson its intellectual father . Emma Curtis Hopkins "the teacher of teachers", Ernest Holmes, founder of Religious Science, the Fillmores, founders of Unity, and Malinda Cramer and Nona L. Brooks, the founders of Divine Science, were all greatly influenced by Transcendentalism . </P> <P> Transcendentalism also influenced Hinduism . Ram Mohan Roy (1772--1833), the founder of the Brahmo Samaj, rejected Hindu mythology, but also the Christian trinity . He found that Unitarianism came closest to true Christianity, and had a strong sympathy for the Unitarians, who were closely connected to the Transcendentalists . Ram Mohan Roy founded a missionary committee in Calcutta, and in 1828 asked for support for missionary activities from the American Unitarians . By 1829, Roy had abandoned the Unitarian Committee, but after Roy's death, the Brahmo Samaj kept close ties to the Unitarian Church, who strived towards a rational faith, social reform, and the joining of these two in a renewed religion . Its theology was called "neo-Vedanta" by Christian commentators, and has been highly influential in the modern popular understanding of Hinduism, but also of modern western spirituality, which re-imported the Unitarian influences in the disguise of the seemingly age - old Neo-Vedanta . </P> <P> Major figures in the transcendentalist movement were Ralph Waldo Emerson, Henry David Thoreau, Margaret Fuller, and Amos Bronson Alcott . Other prominent transcendentalists included Louisa May Alcott, Charles Timothy Brooks, Orestes Brownson, William Ellery Channing, William Henry Channing, James Freeman Clarke, Christopher Pearse Cranch, John Sullivan Dwight, Convers Francis, William Henry Furness, Frederic Henry Hedge, Sylvester Judd, Theodore Parker, Elizabeth Palmer Peabody, George Ripley, Thomas Treadwell Stone, Jones Very, and Walt Whitman . </P> <P> Early in the movement's history, the term "Transcendentalists" was used as a pejorative term by critics, who were suggesting their position was beyond sanity and reason . </P>
