The Perception of Pain
For just a moment, imagine three young friends on the school playground having an in-depth conversation about the color purple. One of the adolescents was born blind and the other two are trying to describe what the color looks like to an individual who has never seen a flower, an eggplant, a crayon, or even a sunset. Imagine that of the two friends with sight, one sees the color purple and is reminded of a big silly dinosaur they grew up watching on TV and the other simply recalls the fresh grapes they ate last summer on a relative’s vineyard. Both are picturing the color purple and both are correct, but they have two very different perceptions of what purple appears to be, based on the input of their other senses. How can these friends describe a sensation or feeling to their blind friend? What does purple feel like or taste like?
