Dylan Thomas's "Do Not Go Gentle Into the Night" was written as a plea to his dying father, David John Thomas, an English grammar teacher who had a powerful influence in his life. Ironically, Dylan Thomas himself died a year later.
While the poem has three parts to it, it is an affirmation of life to the last breath, a refusal to die quietly and passively. In the first part, the speaker provides an introduction to the speaker's message. Then, in the four stanzas that follow, the speaker provides examples of what he means. In telling his father to "rage against the night," the speaker offers examples of what wise, good, brave, and wild men have done:
Old age should burn and rave at close of day
Good men,....crying how bright their frail deeds might have danced in a green bay
Wild men who caught and sang the sun in flight, and learn, too late, they grieved it on its way,
Grave men, near death, who see with blinding sight
Finally, in the last stanza, the tone is much more personal as the speaker addresses father exhorting him to fight against death as a man should.
And, you, my father, there on that sad height,/Curse, bless me now, with your fierce tears, /I pray
Do not go gentle into the night.
