This is from Chuck Colson's blog yesterday-- visit there to read all of it.
So what are the arts and humanities good for? Here is where I think the Christian worldview provides an answer that Fish cannot grasp. They teach that God made humans creative beings, like Himself. The works of art we create—sculpture, literature, drama—reflect the glory and beauty of the Creator of life. This is what gives the arts their intrinsic value. Any beneficial effect that they might have on human thinking—and usually they do have such effects—is a good thing, but it is not why we create, and it does not add or detract from the value of art.
No, the humanities cannot save us, but because their mere existence speaks of and glorifies our Creator, they are more than justified.
