Chapter 14 of 'Biographia Literaria' by S. T. Coleridge discusses the nature of poetry and its distinction from prose, emphasizing two cardinal points: the emotional truth reflective of real life and the imaginative novelty of supernatural elements. Coleridge critiques Wordsworth's poetic style, noting their differing views on the function of poetry, with Coleridge favoring a balance of imagination and reality. Ultimately, the chapter explores the philosophical nature of poetry, its immediate purpose of providing pleasure, and the blend of poetic genius and creativity.
