No, because the thermostat acts on the world in response to temperature.
The retina doesn't act on the world in response to light? It doesn't
send a signal to the brain in the same manner that changes in a metal
strip triggers the HVAC system?

The hypothesis was that the retina was detached from the visual cortex. So it has not way to act on the world. It's like a thermostat that's not connected to the furnace.

I can't believe that you want me to
accept that eyes can't see but metal can. What about our skin, surely
you must give that the same consideration when it contracts into
goosebumps as when a strip of metal contracts in size?

Sure it's acting in the world - not just internally.
