The people of Scotland decide Thursday whether national pride outweighs economic risk.

The vote on independence is taking place without any of the usual factors that drive the dissolution of great nations: no war, no acute economic crisis, no raging territorial dispute. In fact, the situation is quite the opposite: peace, a slowly recovering economy and a central government in London that promises to grant more powers over taxing and spending to the Scottish Parliament.
