“Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.”
Dylan Thomas, “Do Not Go Gentle Into That Good Night”
I think of this poem as a counter balance to Fern Hill, where at the end, the poet sleeps and wakes to find his childhood has fled. This is the older and wiser poet, unwilling to be passive any longer.
