how do we know if we perceive colours the same way?
In: 19
I don’t know if Tommy Edison is still active on Youtube, but he had an old video where he talked about the different ways people have tried to describe color to him. He’s blind since birth, so he has no experience seeing color whatsoever, but he knows what all the different colors are and what they represent. He knows that the sky is blue and so is the ocean, even if water is clear, he knows trees and grass are green unless they’re dead then they’re brown or yellow, he knows fire trucks are red and school buses are yellow, and so on. But he’s never been able to “imagine” color. No one’s ever been able to describe what green looks like, they can only name objects that are green.
