The N.Y. Times Sunday Magazine has a very interesting article (“Getting Iraq wrong“) which talks about how academics and politicians make decisions.
“The philosopher Isaiah Berlin once said that the trouble with academics and commentators is that they care more about whether ideas are interesting than whether they are true. Politicians live by ideas just as much as professional thinkers do, but they can’t afford the luxury of entertaining ideas that are merely interesting…In academic life, false ideas are merely false and useless ones can be fun to play with. In political life, false ideas can ruin the lives of millions and useless ones can waste precious resources. An intellectual’s responsibility for his ideas is to follow their consequences wherever they may lead. A politician’s responsibility is to master those consequences and prevent them from doing harm.”
