McGrath on Liberalism

I’m rereading in preparation for my comments on Alister McGrath’s chapter of Four Views, and I just came across this gem:

Postliberalism has come to terms with the death of the Enlightenment, whereas liberalism, rather like a freshly decapitated farmyard chicken, stumbles pathetically and randomly across the intellectual terrain, looking desperately for an absolutely firm foundation in a world that no longer accepts its existence.

This came out of nowhere, since “postliberalism” is a completely foreign term to me. I’m not sure I’m on board with it, because, from what I’ve been able to pick up about it this evening, it stands against the existence of objective truth in doctrine.  I’ve also never thought of liberalism as attempting to find “an absolutely firm foundation,” but it’s absolutely true that liberal theology believes itself to be rooted in an epistemological bedrock outside of Christianity.  Unfortunately it’s a mirage.
