Obviously these ideas are far from original, and it is clear that Emerson was influenced in his formulation of them by his previous readings of Neoplatonist philosophy, the works of Coleridge and other European Romantics, the writings of Emmanuel Swedenborg, Hindu philosophy, and other sources. What set Emerson apart from others who were expressing similar Transcendentalist notions were his abilities as a polished literary stylist able to express his thought with vividness and breadth of vision. His philosophical exposition has a peculiar power and an organic unity whose cumulative effect was highly suggestive and stimulating to his contemporary readers' imaginations.In a lecture entitled "The American Scholar" (Aug. 31, 1837), Emerson described the resources and duties of the new liberated intellectual that he himself had become. This address was in effect a challenge to the Harvard intelligentsia, warning against pedantry, imitation of others, traditionalism, and scholarship unrelated to life. Emerson's "Address at Divinity College," Harvard University, in 1838 was another challenge, this time directed against a lifeless Christian tradition, especially Unitarianism as he had known it. He dismissed religious institutions and the divinity of Jesus as failures in man's attempt to encounter deity directly through the moral principle or through an intuited sentiment of virtue. This address alienated many, left him with few opportunities to preach, and resulted in his being ostracized by Harvard for many years. Young disciples, however, joined the informal Transcendental Club (founded in 1836) and encouraged him in his activities.
