Coleridge, by H. D. Traill, is a classic biography of the great English poet, Samuel Taylor Coleridge. In a tolerably well-known passage in one of his essays De Quincey enumerates the multiform attainments and powers of Coleridge, and the corresponding varieties of demand made by them on any one who should aspire to become this many-sided man's biographer. The description is slightly touched with the humorous hyperbole characteristic of its author; but it is in substance just, and I cannot but wish that it were possible, within the limits of a preface, to set out the whole of it in excuse for the many inevitable shortcomings of this volume. Having thus made an "exhibit" of it, there would only remain to add that the difficulties with which De Quincey confronts an intending biographer of Coleridge must necessarily be multiplied many-fold by the conditions under which this work is here attempted. Samuel Taylor Coleridge (21 October 1772 - 25 July 1834) was an English poet, literary critic, philosopher and theologian who, with his friend William Wordsworth, was a founder of the Romantic Movement in England and a member of the Lake Poets. He wrote the poems The Rime of the Ancient Mariner and Kubla Khan, as well as the major prose work Biographia Literaria. His critical work, especially on William Shakespeare, was highly influential, and he helped introduce German idealist philosophy to English-speaking culture. Coleridge coined many familiar words and phrases, including suspension of disbelief. He had a major influence on Ralph Waldo Emerson and on American transcendentalism. Throughout his adult life Coleridge had crippling bouts of anxiety and depression; it has been speculated that he had bipolar disorder, which had not been defined during his lifetime.[1] He was physically unhealthy, which may have stemmed from a bout of rheumatic fever and other childhood illnesses. He was treated for these conditions with laudanum, which fostered a lifelong opium addiction.
