Meditation on Slave Narrative

I found myself conflicted by the slave narrative. As much as I respect that as a part of my culture and heritage there are too many issues surrounding it. Was this really written by an escaped slave? How could they write if almost none of them knew how to read? How do we know this isn’t just propaganda? Why risk capture again just to publish a novel? It’s all just too much that makes me really question the validity of a lot of it.
