Take this oft-quoted passage from Ron Suskind's N.Y. Times article "Without a Doubt" - interviewing a Bush White House aide:
"The aide said that guys like me were 'in what we call the reality-based community,' which he defined as people who 'believe that solutions emerge from your judicious study of discernible reality.' I nodded and murmured something about enlightenment principles and empiricism. He cut me off. 'That's not the way the world really works anymore,' he continued. 'We're an empire now, and when we act, we create our own reality.'"
