Thomas Kuhn famously argued that science advances not gradually but in jolts, through a series of raw and jagged paradigm shifts. Somebody sees a problem differently, and suddenly everybody's vantage point changes.

If we had any brains, we'd build an Iraqi C-Span so the whole Arab world could follow this process like a long political soap opera.
