The biography of a great poet has seldom been so written as to enhance his reputation with the world at large. It is almost always the highest artist whose individuality, so to speak, is least discernible in his work, and who, like some divinity, is at his best when his mind and moods, his lofty purpose and his attitude toward the problems of life, are revealed only through the medium which he has chosen for revealing them to mankind. To lay bare the human side of a poet, to retail his domestic history, and to dwell upon his private relations with friends or family, will always interest the public enormously; but for himself it is often a perilous ordeal. The man of restless erratic genius, cut off in his prime like Byron or Shelley, leaves behind him a confession of faults and follies, while one who has lived long takes the risk of intellectual decline; or else, like Coleridge, Landor, and even Scott, he may in other ways suffer loss of dignity by the posthumous record of failings or mistakes. It is a rare coincidence that in this nineteenth century two poets of the first rank--Wordsworth and Tennyson--should each have passed the natural limit of fourscore years, steadily extending their reputation without material loss of their power, and completely fulfilling the ideal of a life devoted to their beautiful art, free alike from adventures and eccentricities, tranquil, blameless, and nobly dignified. Such is the life which has been described to us in the _Memoir_ of Alfred, Lord Tennyson, by his son. In preparing it he had the singular advantage of very close and uninterrupted association for many years with his father, and of thorough acquaintance with his wishes and feelings in regard to the inevitable biography. In a brief preface, he touches, not without emotion, upon the aims and limitations of the task which it had become his duty to undertake. "For my part," he says, "I feel strongly that no biographer could so truly give him as he gives himself in his own works; but this may be because, having lived my life with him, I see him in every word which he has written; and it is difficult for me so far to detach myself from the home circle as to pourtray him for others. He himself disliked the notion of a long, formal biography.... However, he wished that, if I deemed it better, the incidents of his life should be given as shortly as might be without comment; but that my notes should be final and full enough to preclude the chance of further and unauthentic biographies."
