Last night Vicky was talking about the ineffability of inner experience. She told you to imagine what it was like to be a bat. Even if you knew what sonar was and how it worked, you could never know what it feels like to have it, or what it feels like to be a small, furry creature hanging upside down from the roof of a cave. She said that certain facts are accessible only from one point of view - the point of view of the creature who experiences them. You think she meant that the only shoes we can ever wear are our own. Meg can't imagine what it's like for you to be you, she can only imagine herself being you.
