Jackson is a Distinguished Professor at the Australian National University, and a regular visiting professor at Princeton University. His father, Allan Jackson, was a student of Ludwig Wittgenstein.
The argument supposes that a woman, Mary, spends her life in a room where she was unable to see any colour, but nevertheless learns all of the physical facts about colour and colour perception. Jackson then considers what happens when Mary leaves the room and sees colour for the first time. Since it seems obvious that Mary learns something knew upon seeing colour, the existence of something apart from the physical world is demonstrated.
Initially, Jackson used Mary’s Room in order to support his dualist response to the mind-body problem, but later decided that the knowledge argument is more intuitive than it is scientific, and it is actually misleading.
