L. Frank Baum Quote

"Beautiful things may be admired, if not loved," asserted the Tin Man. "Flowers are beautiful, for instance, but we are not inclined to marry them. Duty, on the contrary, is a bugle call to action, whether you are inclined to act, or not. In this case, I obey the bugle call of duty."
