In 1840 he helped launch The Dial, first edited by Margaret Fuller and later by himself, thus providing an outlet for the new ideas Transcendentalists were trying to present to America. Though short-lived, the magazine provided a rallying point for the younger members of the school. From his continuing lecture series, he gathered his Essays into two volumes (1841, 1844), which made him internationally famous. In his first volume of Essays Emerson consolidated his thoughts on moral individualism and preached the ethics of self-reliance, the duty of self-cultivation, and the need for the expression of self. The second volume of Essays shows Emerson accommodating his earlier idealism to the limitations of real life; his later works show an increasing acquiescence to the state of things, less reliance on self, greater respect for society, and an awareness of the ambiguities and incompleteness of genius.His Representative Men (1849) contained biographies of Plato, Swedenborg, Montaigne, Shakespeare, Napoleon, and Goethe. In English Traits he gave a character analysis of a people from which he himself stemmed. The Conduct of Life (1860), Emerson's most mature work, reveals a developed humanism together with a full awareness of man's limitations. It may be considered as partly confession. Emerson's collected Poems (1846) were supplemented by others in May-Day (1867), and the two volumes established his reputation as a major American poet.
