Constitution,—the apex of all its intelligences and mighty instincts and dumb longings: it is I? William Conqueror's big gifts, and Edward's and Elizabeth's; Oliver's lightning soul, noble as Sinai and the thunders of the Lord: these are mine, I begin to perceive,—to a certain extent. These heroisms have I,—though rather shy of exhibiting them. These; and something withal of the huge beaver-faculty of our Arkwrights, Brindleys; touches too of the phoenix-melodies and sunny heroisms of our Shakespeares, of our Singers, Sages and inspired Thinkers all this is in me, I will hope,—though rather shy of exhibiting it on common occasions.
