“It’s absolutely crucial that we don’t conflate this internal reality with the external reality that it’s tracking, because the two are very different. My brain’s internal reality is like the dashboard of my car: a convenient summary of the most useful information. Just as my car’s dashboard tells me my speed, fuel level, motor temperature, and other things useful for a driver to be aware of, my brain’s dashboard/reality model tells me my speed and position, my hunger level, the air temperature, highlights of my surroundings and other things useful for the operator of a human body to be aware of.”

Context: I don't know why I care what people write about me after I'm dead, except that since I invest so much of my time telling the truth in my fiction, I'd hate to see someone play fast and loose with the pieces of my life. I don't care what they might think of me; but I don't want lies about my life used to invalidate the stories. My characters seem real because they are drawn from the realities of my life. I didn't have to research their pain; I just tapped into my own.
