When Heaven sends sorrow,
  Warnings go first,
  Lest it should burst
  With stunning might
  On souls too bright
  To fear the morrow.

Can science bear us
  To the hid springs
  Of human things?
  Why may not dream,
  Or thought’s day-gleam,
  Startle, yet cheer us?

Are such thoughts fetters,
  While Faith disowns
  Dread of earth’s tones,
  Reeks but Heaven’s call,
  And on the wall
  Reads but Heaven’s letters?
Between Calatafimi and Palermo. February 12, 1833.
