The featured article in today’s Opinion Journal is "The Conservative Mind" by Peter Berkowitz, senior fellow at Stanford University’s Hoover Institution. Here are the opening paragraphs.

The left prides itself on, and frequently boasts of, its superior appreciation of the complexity and depth of moral and political life. But political debate in America today tells a different story.

On a variety of issues that currently divide the nation, those to the left of center seem to be converging, their ranks increasingly untroubled by debate or dissent, except on daily tactics and long-term strategy. Meanwhile, those to the right of center are engaged in an intense intra-party struggle to balance competing principles and goods.

One source of the divisions evident today is the tension in modern conservatism between its commitment to individual liberty, and its lively appreciation of the need to preserve the beliefs, practices, associations and institutions that form citizens capable of preserving liberty. The conservative reflex to resist change must often be overcome, because prudent change is necessary to defend liberty. Yet the tension within often compels conservatives to wrestle with the consequences of change more fully than progressives–for whom change itself is often seen as good, and change that contributes to the equalization of social conditions as a very important good.

To be sure, some standard-order issues remain easy for both sides. Democrats instinctively want to repeal the Bush tax cuts, establish government supervised universal healthcare, and impose greater regulation on trade. Just as instinctively Republicans wish to extend the Bush tax cuts, find market mechanisms to broaden health care coverage and reduce limitations on trade.

But on non-standard issues–involving dramatic changes in national security and foreign affairs, the power of medicine and technology to intervene at the early stages of life, and the social meaning of marriage and family, the partisans show a clear difference: the left is more and more of one mind while divisions on the right deepen.

Read the whole thing to see what roils the right, and why.
