His greatest works. From the Introduction: "Coleridge's search, throughout his life, was after the absolute, an absolute not only in thought but in all human relations, in love, friendship, faith in man, faith in God, faith in beauty; and while it was this profound dissatisfaction with less than the perfect form of every art, passion, thought, or circumstance, that set him adrift in life, making him seem untrue to duty, conviction, and himself, it was this also that formed in him the double existence of the poet and the philosopher, each supplementing and interpenetrating the other. " According to Wikipedia: "Samuel Taylor Coleridge (1772 – 1834) was an English poet, critic and philosopher who was, along with his friend William Wordsworth, one of the founders of the Romantic Movement in England and one of the Lake Poets. He is probably best known for his poems The Rime of the Ancient Mariner and Kubla Khan, as well as his major prose work Biographia Literaria."
