Imagine, Bishop, that you have a beloved cat, but that your cat is not with you. If you close your eyes and further imagine you are petting your cat, the same neurons in your brains are activated as if you were petting the actual cat. Our minds may know the difference between its models and reality itself, but it prefers its models. So much so that we apprehend reality through our models, rather than directly via the sense. When I'm speaking to you, I have a little bishop in my head, and though I speak out load, I'm speaking to my little bishop. When you answer, I can only perceive you through my model of you. Mentars also make models, but they don't apprehend reality through them. They end up, not with little people in their minds, but with highly complex rule sets. They relate to their models in the same way we relate to weather models, as things to consult, but not to conflate with external reality.
