“The Historian and the Man of Science alike may be said to traffic with the dead. Cuvier has imparted flesh and motion and appetites to the defunct Megatherium, whilst the living ears of M.M. Michelet and Renan, of Mr. Carlyle and the Brothers Grimm, have heard the bloodless cries of the vanished and given them voices. I myself, with the aid of the imagination, have worked a little in that line, have ventriloquised, have lent my voice to, and mixt my life with, those past voices and lives whose resuscitation in our own lives as warnings, as examples, as the life of the past persisting in us, is the business of every thinking man and woman.”
