What mood is conveyed in the poem "Do Not Go Gentle into That Good Night" by Dylan Thomas?

The mood conveyed in "Do Not Go Gentle into That Good Night" is indeed urgent and defiant. This is evident through Thomas's use of imperative language and a consistent structure that emphasizes the speaker’s insistence on resisting death. The repeated exhortation to "rage against the dying of the light" underscores a fierce determination to fight against the inevitability of death, which reflects a sense of urgency.

The poem explores various attitudes towards death, but the prevailing emotional tone is one of defiance—not just a resignation to life’s end, but a passionate plea to confront it head-on. This creates a sense of urgency, as the speaker addresses his father and implores him to resist passively accepting death. Thus, the combination of strong emotions, powerful imagery, and the fervent plea for resistance establishes this urgent and defiant mood throughout the poem.
