But while reactionary thought is prone to real wickedness, it also contains real insights. (As, for the record, does Slavoj Zizek — I think.) Reactionary assumptions about human nature — the intractability of tribe and culture, the fragility of order, the evils that come in with capital-P Progress, the inevitable return of hierarchy, the ease of intellectual and aesthetic decline, the poverty of modern substitutes for family and patria and religion — are not always vindicated. But sometimes? Yes, sometimes. Often? Maybe even often.

Both liberalism and conservatism can incorporate some of these insights. But both have an optimism that blinds them to inconvenient truths. The liberal sees that conservatives were foolish to imagine Iraq remade as a democracy; the conservative sees that liberals were foolish to imagine Europe remade as a post-national utopia with its borders open to the Muslim world. But only the reactionary sees both.
