"I feel the poet does write on memory but... Wasn't it Aristotle who said the historian keeps the factual record of mankind and the poet writes the emotional history of mankind? I think you can read a history of Vietnam and know that so many men under the age of twenty were killed, or you can read Tim O'Brien and you can "feel" those deaths. O'Brien is preserving the emotional history of Vietnam. A historian is preserving the facts."
