Not so fast. Think about what Telmo is saying. When the
added the ability to sense in IR to the mouse, that aspect or
of sense would have to be integrated into the totality of the
those mice. The dual aspect idea shines here! For any physical system
there is at least one representation and for every representation
is at least one object. Given an initial object: Mouse there is a
representation of that mouse to that mouse: it's internal Sense of
a mouse in the world.
When we add the IR apparatii to the mouse's body, then there
new representation necesary, no? We no longer have the Mouse minus IR
Not necessarily a new representation. It could just itch in a new
place or something. It could have some novelty though, but I think
that has to do with then nature of the electrode, not the IR.
Right, but consider the experiements where blind humans where
rigged up with a camera and an array of electrodes on their stomach or
such... I recall reports of some limited success in the transposition of
the sensations from the stomach to the general location of the camera,
but I am chalking that up to the auto-integrator of the brain. How that
works, is interesting...

Why not, so long as there is another turtle to add to the
Exactly. What's the alternative? Different animals all the way down?
No animal after turtles? It doesn't really apply to how I think of
sense though, since at the absolute level, all distinctions are
neutralized and retained at the same time. Where sense becomes so thin
and so broad that all experiences in history are united in a single
instant, it's not really a turtle.
OK, don't push an analogy too far...
