Coleridge was one of the greatest English poet-critics. He produced works of the highest order but was incapable of sustained, persistent labor. He is known for his works Biographia Literaria and Lectures on Shakespeare and Other Poets. Coleridge discussed themes of poetry, poetic diction, the language of rustics versus townsmen, natural versus supernatural poetry, and his final definition of a poem as proposing pleasure rather than truth through parts that provide distinct gratification forming a whole compatible delight. He focused on the creative process over analysis and established philosophical principles for literary criticism.
