What it is like to be bat, eh?  Somehow the bat navigates in space (and
time) to find food.  From a pure engineering point of view, that's pretty
amazing technology. I hadn't really appreciated it that way the first time
I read Nagel's question.

I wonder if we model higher dimensional navigation for similar goals.
Maybe we can reach consensus on what it's like to be a bat... but some will
still claim that's not enough to know what it IS to be a bat.
