Pedro Calderón de la Barca,
Life Is a Dream
“ And, whether wake or dreaming, this I know, How dream-wise human glories come and go; Whose momentary tenure not to break, Walking as one who knows he soon may wake, So fairly carry the full cup, so well Disorder'd insolence and passion quell, That there be nothing after to upbraid Dreamer or doer in the part he play'd, Whether To-morrow's dawn shall break the spell, Or the Last Trumpet of the eternal Day, When Dreaming with the Night shall pass away. ”
