Perhaps Daniel Patrick Moynihan's was the only strong opposing voice because he admitted the dilemma three decades ago. For any thinking liberal, this must be a time of enormous confusion. Part of the confusion is over practical dilemmas. But the more serious confusion is intellectual. At a time like this the essential virtues are imagination, self-scrutiny, a willingness to question the most basic ideas.
Confusion serves the beneficial purpose of leaving one to the mercies of experience.
But allowing experience to make an impression requires an effort of will. By habit we know what we think, especially in public. You can read a long article apparently full of the spirit of self-questioning and discover at the end that the author hasn't entertained one really new thought, like a dog sniffing all over the yard before going to squat in the same old spot. Confusion requires training. It might even be a good idea to start a file of items that suggest you were wrong.
