Altering Common Sense

I was affected by some of Angus's arguments in Emergent Publics. He suggests that the changes which are necessary for sustaining democracy in America require a shift in America's perception of what the solutions are. The altering of common sense one could say. But how could this be? Common sense is the foundation on which we all move: common sense is the laws of physics, the color of the sky, the life-death cycle. Could there be anything more difficult than stripping and restocking the elements of our common sense? In my essay, I plan on interpreting what is meant by the altering of common sense, how it could possibly be done, and what it means to Americans.
