Going back to a four-week-old discussion about poems: http://www.theyeshivaworld.com/coffeeroom/topic/random-questions/page/13
Do not go gentle into that good night by Dylan Thomas – an entreaty against the acceptance of old age’s infirmity and death’s inevitability. Ironically written by a shikkur who drank himself to death at a young age.
I Have a Rendezvous with Death by Alan Seeger – haunting, well written, and prescient poem by an American volunteer fighting in WWI. As he foretold, he died in combat while still in his twenties.
