A Reaction

This strikes me as a real possibility, not just a wild speculation. It seems pretty obvious to me that I operate by blindsight in many aspects of my behaviour. Piano-playing would be impossible if all qualia had to be processed.


The 7 ideas with the same theme [evidence of perception without consciousness]:

We can't know by sight or hearing without realising that we are doing so [Fichte]
In peripheral vision we see objects without their details, so blindsight is not that special [Dennett]
Blindsight subjects glean very paltry information [Dennett]
Fish may operate by blindsight [Lockwood]
In blindsight both qualia and intentionality are missing [Chalmers]
In blindsight V1 (normal vision) is inactive, but V5 (movement) lights up [Carter,R]
The brain may have two systems for vision, with only the older one intact in blindsight [Lowe]
