183 One’s-Self I Sing (1867) By Walt Whitman

  One’s-self I sing, a simple separate person,
  Yet utter the word Democratic, the word En-Masse.

  Of physiology from top to toe I sing,
  Not physiognomy alone nor brain alone is worthy for the Muse, I say
      the Form complete is worthier far,
  The Female equally with the Male I sing.

  Of Life immense in passion, pulse, and power,
  Cheerful, for freest action form’d under the laws divine,
  The Modern Man I sing.
