> What you think third party observable behavior means is the set of all 
properties which are externally discoverable. I am saying that is a 
projection of naive realism, and that in reality, there is no such set, and 
that in fact the process of discovery of any properties supervenes on the 
properties of all participants and the methods of their interaction.

My point of using cats in this thought experiment is to specifically point 
out our naivete in assuming that instruments which extend our perception in 
only the most deterministic and easy to control ways are sufficient to 
define a 'third person'. If we look at the brain with a microscope, we see 
those parts of the brain that microscopes can see. If we look at New York 
with a swarm of cats, then we see the parts of New York that cats can see.

This is the point of the thought experiment. The limitations of all forms 
of measurement and perception preclude all possibility of there ever being 
a such thing as an exhaustively complete set of third person behaviors of 
any system.

What is it that you don't think I understand?
