" Historically, American liberals have been idealists, pressing forward toward the goals of greater freedom, social equality, and more meaningful democracy. The articulate exposition of a liberal ideology was necessary to convert others to liberal ideas and to reform existing institutions continuously along liberal lines. Today, however, the greatest need is not so much the creation of more liberal institutions as the successful defense of those which already exist. This defense requires American liberals to lay aside their liberal ideology and to accept the values of conservatism for the duration of the threat. Only by surrendering their liberal ideas for the present can liberals successfully defend their liberal institutions for the future. Liberals should not fear this change. Is a liberal any less liberal because he adjusts his thinking so as to defend most effectively the most liberal institutions in the world? To continue to expound the philosophy of liberalism simply gives the enemy a weapon with which to attack the society of liberalism. The defense of American institutions requires a conscious articulate conservatism which can spring only from liberals deeply concerned with the preservation of those institutions. As Boorstin, Niebuhr, and others have pointed out, the American political genius is manifest not in our ideas but in our institutions. The stimulus to conservatism comes not from the outworn creeds of third-rate thinkers but from the successful performance of first-rate institutions. …
Conservatism does not ask ultimate questions and hence does not give final answers. But it does remind men of the institutional prerequisites of social order. And when these prerequisites are threatened, conservatism is not only appropriate, it is essential. In preserving the achievements of American liberalism, American liberals have no recourse but to turn to conservatism. For them especially, conservative ideology has a place in America today. "
