I will take again the case of a physiologist who is examining someone else's brain. ... What the physiologist sees, if we mean by this something that he experiences, is an event in his own mind and has only an elaborate causal connection with the brain that he imagines himself to be seeing. ... In the brain that he thinks he is seeing there are quantum transitions. These lead to emission of photons, the photons travel across the intervening space and hit the eye of the physiologist. They then cause complicated occurrences in the rods and cones, and a disturbance which travels along the optic nerve to the brain. When this disturbance reaches the brain, the physiologist has the experience which is called "seeing the other man's brain.
