We can all agree that there is more to knowing someone than merely knowing a collection of facts about them. The latter we might call knowing about them, whereas the former is simply knowing them. James Chastek has recently written a blog post in which he distinguishes two senses of experience: (i) experience as sensation, and (ii) experience as an ordering idea. I wonder if this knowing someone or something is not closely related to this second sense of experience? Perhaps to know someone just is to have an ordering idea about them.
