Samuel Taylor Coleridge was one of the Romantic age's most enigmatic figures, a genius of astonishing diversity; author of some of the most famous poems in the English language, and co-author, with Wordsworth, of Lyrical Ballads; one of England's greatest critics and theorists of literature and imagination; as well as autobiographer, nature-writer, philosopher, theologian, psychologist, and talker. Throughout his life, he confided his thoughts and emotions to his Notebooks, where we can still see his speculations and observations taking shape. This edition presents a selection from this unique work, newly presented, with notes and commentary, for the student as well as the general reader.
