the lecture "Poetry and Eloquence," given in Boston in 1847, and in England in 1848. To the lecture called "Poetry and English Poetry," given in Philadelphia in 1854, it owes almost all of the "Introductory" matter (except, I think, the remarkable sentence about John Hunter); the passages in "Imagination" about the world being anthropomorphized, and defining Fancy and Imagination, with a few other sentences; the paragraph in "Veracity" beginning "For poetry is faith;" that in "Creation" beginning "The poet is enamoured of thoughts and laws," and the sentence concerning the necessity of the poet's thought, which he did not make, but which "made him, and the sun and the stars;" also several passages in "Melody, Rhyme, Form." In 1861 Mr. Emerson gave a course in Boston on Life and Literature, and one of the lectures, which is not preserved, was called "Poetry and Criticism in England and America." It is probable that many sheets that did duty in the courses on the Natural History of the Intellect, at Cambridge, may have been used in the essay, which seems to have been brought by Mr. Emerson to its present size and form when, under the final title "Poetry and Imagination," he read it, as two lectures, at Chickering Hall in April, 1872.
