This is a poem about the joy and sadness that comes with the flash of a burning life soon to be extinguished with nothing more than 'a sigh. It focuses on sadness as those we care for enter far too gently into that good night. Of those who left before their time. As this poem was written specifically for Thomas's dying father, it is made even more poignant by the emotional weight the words carry. This poem radiates with intensity, especially the beginning of the line: wild men who caught and sang the sun in flight is simply beautiful poetry. Addressed to the poet's father as he approaches blindness and death. The relevant aspect of the relationship was Thomas's deep respect for his father, tall and strong in Thomas's passionate spirit but now tamed by illness and the passage of time. Acceptance of death and peaceful rest afterwards are cast aside in favor of a brutal rage so blind that it almost reflects the vigor of childhood frustration with the nature of things we are powerless to change . Furthermore, the poem is as much about the loss of love and the feelings of the one left behind as it is about death itself. The meaning of the poem remains shrouded in metaphors such as references to the night as being “good”. He recognized that his father was somewhere he had not been and that he may have seen what he could not see. Thomas was not ready to give up such an important part of his life, even though his father was facing an irreversible change, and Thomas' grief was perhaps all the greater. His statement about this love and this sorrow remains touching. Perhaps his missing father's feelings should have been more important than his own rage. These emotions seem to be unquestioned throughout the poem, even as the style invites structure and discipline in the theme of "night" and "light." In the tercets, Thomas gives examples of men who face death in different but similar ways. The first are “wise men”, perhaps philosophers. They know that “dark is good” because they know what to look for at the end of life. However, despite their wisdom, they “do not go gently” because their words “have not caused lightning.” This phrase has the force of a symbol suggesting that wise men did not have the ultimate power of nature. Thomas therefore seems to be saying that the wise men were not wise enough, that their words created no ultimate linguistic reality but vague speculations about death as a good thing. Subsequently, the good men of the third tercet let life pass them by. The festive imagery of “Their fragile acts could have danced in a green bay” evokes a wonderful world of joyful activities in contrast to the “fragile acts.” Why, we ask ourselves, do good men regret the past just as the last wave passes? As for the style, it is most certainly an elevated style of poetic diction within a villanelle format. The term originates from Italy (Italian villanella from villano: “peasant”); and later used in France to designate a short poem of a popular nature favored by poets of the end of the 16th century. Five tercets are followed by a quatrain, the first and last lines of the stanza being repeated alternately as the last lines of subsequent stanzas and brought together in a couplet at the end of the quatrain. The stanza is repeated for dramatic effect and tone: Rage, rage against the dying of light. In this case, this particular stanza, deriving much of its impact from repetition and variation, paints a clear and precise picture of the author's strong emotions. And.
