The poem "Do Not Go Gentle into That Good Night" by Dylan Thomas is a poem about death. The narrator of the poem is experiencing the death of his father, which we see in the last stanza, or group of lines. Witnessing the death of his father makes the speaker think about death in a more general way. The refrains "Do not go gentle into that good night" and "Rage, rage against the dying of the light" emphasize the importance of resisting death and fighting fiercely against it . The speaker emphasizes that older men should fight fiercely and strongly against death .
