| I read a very interesting book on how blind people understand language related to sight... It covered many topics but in particular went over the philosophical side of it..... Basically, I think yes, blind people (either form birth or from later in life) do "visualise" in dreams, but it's a moot point becuase if you have ben blind from birth, you would have no idea that these "visualisations" are sight, as you'ld have no reference point for it in waking hours.....
Just as the visual universe is there, even though blind people cannot see it, and was there before sighted creatures evolved and would still be there if sighted creatures never came into existence, so, presumably whole dimensions of reality into which a sensory apparatus different to any which any of us posses would plug us, may be there all the time without our knowing.
Another one... I like the story about a sighted man who finds himself on a planet populated by people without sight. He keeps on telling the people what he can see, and in the end the un-sighted people put out his eyes to "cure" his madness. Think it might come from an HG Wells story. Not sure though. |
