Is there anything in this argument that can't be equally applied to religion? _"Some truth can be captured by the scientific method. But not all. Some deep truths about human nature require instead the reflection provoked by [prayer, religious experience, etc]"_
Maybe there's value in literature, but I don't know if "truth" is the right word for it. I find when people find "truth" in literature, they're mostly using fictional anecdotes to support their preconceived notions about human nature and/or morality. They interpret the books in ways that support what they already think is true.
