A realignment is taking place in the politics of this country and indeed of the world at large. It is increasingly difficult to define the meanings of left and right, liberal and conservative . . . A rift is opening at right angles, so to speak, to the old borders of contestation. The rift, I will argue, is not between left and right but between libertarian and communitarian. Or perhaps we could say that in the intellectual absence of the left, an inherent rift in the right is becoming the new locus of debate, and the remnants of the left are having to choose one side or the other.There's a lot here, compressed into a relatively short, evenhanded essay. Spend some time over the weekend reading the rest. It's worth it.
