“Certainly, the contradiction of tensions and divisions between the followers of different religious traditions, sadly, cannot be denied. However, is it not also the case that often it is the ideological manipulation of religion, sometimes for political ends, that is the real catalyst for tension and division, and at times even violence in society?”

How to Understand Politics: What the Humanities Can Say to Science (2007)
Context: The simplified notion of self-interest used by our political and social science cannot tolerate the tension between one’s own and the good, for that tension leaves human behavior unpredictable. One cannot penetrate into every individual’s private thoughts, and there is no clear way to judge among different conceptions of the good. So in order to overcome the tension, science tries to combine one’s own and the good in such a way as to preserve neither. It generalizes one’s own as the interest of an average or, better to say, predictable individual who lives his life quantifiably so as to make its study easier for the social scientist. And for the same purpose it vulgarizes the good by eliminating the high and the mighty in our souls (not to mention the low and vicious), transforming our aspiration to nobility and truth into personal preferences of whose value science is incognizant, to which it is indifferent.

interview with Locus Magazine, June 2008
Context: Writers are a basically insecure bunch. We are convinced that everything we do sucks, all the time. It's something you have to fight.

And I think there's a real tension between sophistication and accessibility.

Six Principles of Political Realism, § 4.
Politics Among Nations (1948)
Context: Political realism is aware of the moral significance of political action. It is also aware of the ineluctable tension between the moral command and the requirements of successful political action. And it is unwilling to gloss over and obliterate that tension and thus to obfuscate both the moral and the political issue by making it appear as though the stark facts of politics were morally more satisfying than they actually are, and the moral law less exacting than it actually is.
