Postmodernism is anathema to Christianity. It is time that progressive Christians said this clear and loud. Two good reasons for this protest spring to mind:
1. Postmodernism abandons truth.
One of the classic definitions of postmodernism is that it rejects all neta-narratives (a meta-narrative is an overarching story that makes sense of all other stories). This should immediately make Christians suspicious - for what is Christianity if not a meta-narrative!
But more than this, the abandonment of meta-narratives is a sign of the postmodern abandonment of truth. For postmodernism, truth is sidelined. (It's never actually rejected, as that would involve a new form of truth.) With truth sidelined, two things happen. Firt, you can pick your own truth; anything goes. And second, there is an absence of commitment to anything. If anything this second is more dangerous.
Jacques Derrida, one of the fathers of postmodernism, famously said that the writer cannot own the text. So a wag decided to test this and re-published Derrida's works without paying Derrida. Derrida sued for breech of copyright and won. So much for not owning the text!
Our financial system is anything but postmodern - it is not ironic, it has absolute standards and it very definately has a meta-narrative. While this is so, we do not live in a postmodern world. We cannot - postmodernism simply doesn't account for one of the key building blocks of the world.
If it were only a matter of bad description, then postmodernism would be incorrect but harmless. But the postmodern blindspot to the way in which money and the financial system work actually enables those espousing postmodernism to forget about it. Or to put it another way, postmodernism is another way for rich people to ignore poor people. How many postmodern theorists live in the developing world? Ever wondered why not? Postmodernism is blind to the fact that it is the affluence of the few that make it possible. Irony and choice depend on a material basis. The virtual world is parasitic on the material world.
So that's why I'm allergic to postmodernism. It's dangerous. Christians should have nothing to do with it.
Well, I did warn you it was a rant ...
