There's a fair amount of American bashing here. OK, fair enough. Much of it is deserved.
But the greatest documents, the greatest ideas of all time are: the Declaration of Independence, the Constitution, and the Bill of Rights.
Much of the thought that went into these documents came from great European thinkers of the time, but those specific three documents impacted the world in a truly remarkable, revolutionary way.
Not just America; the entire world, two hundred some odd years later, is a better place for these three documents.
