Messrs. Packer, Dionne and Tanenhaus underestimated what the conservative tradition rightly emphasizes, which is the high degree of unpredictability in human affairs. They also conflated the flagging fortunes of George W. Bush’s Republican Party with conservatism’s popular appeal. Most importantly, they failed to grasp the imperatives that flow from conservative principles in America, and the full range of tasks connected to preserving freedom.

Progressives like to believe that conservatism’s task is exclusively negative—resisting the centralizing and expansionist tendency of democratic government. And that is a large part of the conservative mission. Progressives see nothing in this but hard-hearted indifference to inequality and misfortune, but that is a misreading.

What conservatism does is ask the question avoided by progressive promises: at what expense? In the aftermath of the global economic crisis of 2008, Western liberal democracies have been increasingly forced to come to grips with their propensity to live beyond their means.
