no replays.......................

 

It is often said that history provides us with no action replays.  It is not given to controlled experiments.  We only learn what can go wrong after it has already done so, and by then it is too late to put it right.  In fact, the history of freedom in the modern world can be seen as a testing ground for different conceptions of politics.
