Simile in Do Not Go Gentle into That Good Night

In this poem by Dylan Thomas, the speaker reveals his own view on death. One way he uses show this is through a simile in line 14: "Blind eyes could blaze like meteors and be gay". The paradox used in the line before, "blinding sight", explains the speaker's theory about death. Death is a fact of life that none of us can avoid. Often times older people or people with a terminal disease say they have come to grips with death and have accepted it. They know they will be home when they die and look forward to that. The speaker says these people have "blinding sight" so blinding that they have accepted death. But, even these people will fight death. We all fight death, even the wisest of the the wise; because, we are human. He uses this to help his father to have the courage to "rage, rage against the dying of the light".
