Metaphors and repetition in Do Not Go Gentle Into That Good Night In "Do Not Go Gentle Into That Good Night" by Dylan Thomas, the speaker is a son who speaks to his elderly father and implores him to fight against death. The son knows that death is the inevitable end of every life, but he feels that one should not give in to death too easily. Using metaphors, images, and repetition, Thomas reinforces his son's message that aging men see their lives with sudden clarity and realize how they could have lived happier, more productive lives. These men lash out against fate, fighting for more time to make things right. The son uses darkness and the end of day as metaphors for death. He tells his father that "old age should burn and rave" at death rather than fade and slip away peacefully.
