Due out in September, by Daron Acemoglu and James Robinson, here is an excerpt from the Amazon summary:
State institutions have to evolve continuously as the nature of conflicts and needs of society change, and thus society’s ability to keep state and rulers accountable must intensify in tandem with the capabilities of the state. This struggle between state and society becomes self-reinforcing, inducing both to develop a richer array of capacities just to keep moving forward along the corridor. Yet this struggle also underscores the fragile nature of liberty. It is built on a fragile balance between state and society, between economic, political, and social elites and citizens, between institutions and norms. One side of the balance gets too strong, and as has often happened in history, liberty begins to wane. Liberty depends on the vigilant mobilization of society. But it also needs state institutions to continuously reinvent themselves in order to meet new economic and social challenges that can close off the corridor to liberty.
