You don't need to "know" anything to pull your hand away in the reflex
arc. That's like asking how a balance "knows" one side is heavier.
There's no knowing, just some glorious engineering. In fact, animals
have shown reflex arc activity with spine completely severed - cats
can go through the motions of walking if supported on a moving
treadmill with a transected spine. And therefore there's no
involvement of cerebellum. None. Whatsoever. And there's no problem
with that.

Thanks for the the concise and coherent posts, Ken, I can understand
what you're talking about here.
