Postmodernism provides a good critique of modernism. Postmodernism helpfully stresses the use of the aesthetic. Contrary to postmodern claims, practical experience shows that accurate communication is possible. Even postmodern authors expect to be understood. As we work with a text, we can come to an increased understanding, even if not a perfect knowledge.
Postmodernism frequently offers an indefensible foundational thesis.
It does not allow for us to get closer to the true meaning of something over time. Postmodernism, like modernism, is characterised by astounding arrogance. If postmodernism destroyed the arrogance of modernism, it now says that if there is a God, we could not know it. We now come back to Paul in Athens in Acts 17 and his speech at the Areopagus. Paul confronted a society as different in worldview to the Judeo Christian worldview as is our current society.
