a tyranny of reason?

"The trouble with coercion through reason, however, is that only the few are subject to it, so that the problem arises of how to assure that the many, the people who in their very multitude compose the body politic, can be submitted to the same truth. Here, to be sure, other means of coercion must be found, and here again coercion through violence must be avoided if political life as the Greeks understood it is not to be destroyed. This is the central predicament of Plato's political philosophy and has remained a predicament of all attempts to establish a tyranny of reason."
-Hannah Arendt, "What Is Authority?", 1958ish, collected in "Between Past and Future"
