This is an excerpt from something that he once wrote for the New York Times.
“You might consider them romantics, fighting in a doomed cause for something greater than their self-interest. And even though men like Mr. Berg would identify with a cause, Communism, that inflicted far more misery than it ever alleviated—and rendered human dignity subservient to the state—I have always harbored admiration for their courage and sacrifice in Spain.
“I have felt that way since I was boy of 12, reading Hemingway’s For Whom the Bell Tolls in my father’s study. It is my favorite novel, and its hero, Robert Jordan, the Midwestern teacher who fought and died in Spain, became my favorite literary hero. In the novel, Jordan had begun to see the cause as futile. He was cynical about its leadership, and distrustful of the Soviet cadres who tried to suborn it.
“But in the final scene of the book, a wounded Jordan chooses to die to save the poor Spanish souls he fought beside and for. And Jordan’s cause wasn’t a clash of ideologies any longer, but a noble sacrifice for love.
‘“The world is a fine place and worth the fighting for,’ Jordan thinks as he waits to die, ‘and I hate very much to leave it.’ But he did leave it. Willingly.”
