From Beyond Foundationalism, pp. 21-22:

Broadly speaking, the term postmodern implies the rejection of certain central features of the modern project, such as its quest for certain, objective, and universal knowledge, along with its dualism and its assumption of the inherent goodness of knowledge. It is the critical agenda, rather than any proposed constructive paradigm to replace the modern vision, that unites postmodern thinkers.

          The Protestant Reformation provides an example of a similar situation. The sixteenth-century Protestants were in agreement that the medieval Roman Catholic tradition had corrupted the Christian faith and so made the reformation of the church necessary. Although they were united in what they were against, when it came to the task of setting forth a positive agenda they were fragmented.

 In light of this, it seems odd that when you click on the BTS link What do we mean by "Postmodern"? you get no definition at all, it's just something that's new and everywhere.  Of course, if the definition that is in Beyond Foundationalism was repeated on the web site, readers might wonder why postmodernism was being compared to the Protestant reformation, and readers might get the implication that if they don't go along with postmodernism, then they are like those bad old papists that opposed Luther.

Shouldn't we start by asking some simple questions, like what does the Bible say about knowledge and the quest for knowledge?  Can Christians just decide what they want to believe about these things?  Does the Bible have or presume or imply an epistemology?  At the WTS conference discussed elsewhere on this site (see under News), Scot McKnight described himself as a soft postmodernist.  He also said that he just wanted to follow in the way of Jesus.  During the question & answer session I asked him how those two things go together.  In other words, where do you get soft postmodernism from the teaching or example of Jesus?  What was his answer?  Well, I saw his lips moving, but he sure didn't give any answer from the Bible.

 I suppose most everyone would agree that there are few philosophies that are all bad.  I'm with the postmoderns as far as preferring stories to boring philosophical types of sermons, maybe that's one reason I got into Old Testament studies (lots of historical narrative).  Interesting, though, in those narratives I think we see pretty clearly brought out the devastating consequences of throwing out propositional truth.  Can I mention again the Book of Judges?
