Ronald Dworkin on American Politics
If the two-cultures view is right, the lack of argument in American politics is understandable and inevitable. The split between the two cultures would be an unbridgeable gulf separating the comprehensive and wholly clashing worldviews of two Americas. If that is so—if the division between the two cultures is not just deep but bottomless—then there is no common ground to be found and no genuine argument to be had. Politics can be only the kind of war it has become. Many students of our politics think that that is our situation, and they may be right. But that would be alarming and tragic. Democracy can be healthy with no serious political argument if there is nevertheless a broad consensus about what is to be done. It can be healthy even if there is no consensus if it does have a culture of argument. But it cannot remain healthy with deep and bitter divisions and no real argument, because it then becomes only a tyranny of numbers.
