How can we make the governments on which we depend for our welfare and survival behave like servants rather than masters? This is the oldest question in politics. It has been grappled with, but never satisfactorily answered, for thousands of years. In much of the world states remain oppressive, secretive and violent. It is no surprise that so much recent political theory has been concerned with how to protect people from dangerous states. Yet the only things as bad as states that are too strong are states that are too weak. This book explains why we have arrived at this point, what can be done to change the world, and see the power of governments used for good.
