Thanks. I'm not sure, though, how your point is supposed to be inconsistent with what I say in the article. I've proposed a similarly pragmatic account of understanding in epistemology, although I don't emphasize the trendy topic of personal identity. Elsewhere, though, I do talk a lot about the role of the narrative self, and about how we're saturated in stories, as in fictions.
The question, I suppose, is whether all stories are equally valid. Even the stories we'd tell to assimilate data to our personal identities should incorporate objective facts. Otherwise, the narrative would be strictly delusional. Thus, I argue that all knowledge that's understood (as opposed to being just calculated or manipulated with no intuitive grasp of the phenomenon) has objective and subjective components.
