To suffer woes which Hope thinks infinite; To forgive wrongs darker than death or night; To defy Power, which seems omnipotent; To love, and bear; to hope till Hope creates From it's own wreck the thing it contemplates; Neither to change, not falter, nor repent; This, like thy glory, Titan, is to be Good, great and joyous,beautiful and free; This is alone Life, Joy, Empire, and Victory
'Prometheus Unbound' (1820) act 4, l. 570
