Ok, so have little philosophy background other than a few undergrad classes so I apologize if this is just plain ridiculous. This is a scenario I have pondered for awhile now and I wanted to see what everyone else thinks. [begin scenario] A simple scenario; two children in preschool (child A and child B), in different cities blissfully unaware of each others existence. Two sets of colored blocks which were made at the same place to the same specifications; one set is sent to each preschool mentioned previously. One day the teachers at each of the respective schools is teaching the children about the colors in the rainbow. Each teacher points at the green block......"Green". [/end scenario] Now, the question is do child A and child B perceive the color green in the same way? You could put them in the same room and ask them both the same question and they would each point at the same block if you asked for the green block. But who is to say that the color that child A perceives as green isn't what child B would perceive as purple (or any other color for that matter) if child B could see child A's point of view? But because they have both been taught from a mutual reference point they both identify the color of the block as green. Does that make sense?
