Jonah Goldberg on certainty:
The rot, not surprisingly, has reached Hollywood. For example, in Star Wars: Episode III — Revenge of the Sith, George Lucas caved to the fashionable anti-absolutism that comes with Bush hatred by having a young Obi-Wan Kenobi proclaim, “Only a Sith lord deals in absolutes!” Translation: Only evil people see the world as black-and-white. This signaled that Lucas’s descent into hackery was complete, since it was Lucas himself who originally explained that the entire universe is divided into light and dark sides.
Longtime New York Times columnist Anthony Lewis captured the thought nicely a few years ago when he said that a primary lesson of his entire career was that “certainty is the enemy of decency and humanity in people who are sure they are right, like Osama bin Laden and John Ashcroft.”
Whenever I hear people say such things, I like to ask them, “Are you sure about that?” When they say yes, which they always do, I follow up by asking, “No, no: Are you really, really certain that certainty is bad?” At some point even the irony-deficient get the joke.
Goldberg goes on to explain that what these people really hate isn't certainty, but people who are certain of things they disagree with.
