This post brings up an interesting conundrum: why does fiction sometimes equal or transcend the ability of nonfiction to touch someone? People see a headline or a paragraph and are able to distance themselves from a real tragedy. On the other hand have that person read their favorite novel in which they lose a major character and they feel real sadness.
The way one looks at the question depends on several assumptions. I’m not sure that it’s fair to say that fiction is entertainment. For example, a certain fiction book depicts imaginary civilizations in expressing a powerful theme of racial tolerance. Is this in some way less meaningful than a book about Apartheid in teaching the same lesson of racial tolerance? Jesus’ parables in the Bible are essentially short stories. Their power is in creating understanding and is in no way restricted by whether events did or did not actually “happen”.
