The government of the United States was developed under the idea that nobody knew how to make government, or how govern. The result is to invent a system to govern when you don’t know how. And the way to arrange it is to permit a system, like we have, wherein new ideas can be developed and tried out and thrown away. The writers of the Constitution knew of the value of doubt.
