Philistine

A week or two back I heard a report on the TV that North Korea had called President Bush a "Philistine." That stuck in my head because I didn't know the significance of the term. I wondered what was meant by it and how North Korea thought it applied to Bush. I wondered if there was some inference to the Philistine people spoken of in the Bible.
Here's a Yahoo news report on the incident:

Today I looked up the term Philistine in the online encyclopedia Wikipedia and was referred to the term Philistinism. I can see now why one might use that term to describe Bush.

But I'm ashamed to say that for most of my life one might have used that term to describe me as well.
