which got me thinking.
Colourblindness is essentially a group of people who cannot perceive a certain quality that everyone else takes as part and parcel of nature and the universe. But the funny thing is, colour doesn't exist as what we think it is. On a Subatomic level (or something like that, my physics is quite fuzzy), colour is merely a certain wavelength of electromagnetic radiation. In other words, it is just a vibration of a thing. Likewise, so is sound, albeit vibrations of another thing. These vibrations have no meaning until it enters our brains (not exactly the way you think but ok) where it manifests itself as an image. So our brains are the only thing that make any of these meaningful in anyway.
So for something other than a human, i.e a dog, he would not be able to perceive colour. But it wouldn't matter to him because all dogs cannot perceive colour. So if a dog were to "speak" to another dog, he wouldn't say something like "hey, check out the tasty brown steak" because colour doesn't exist in their minds.
Colourblindness is merely a disability whereby others can see what you cannot. What if inherently, inside everyone except you they could perhaps taste a certain flavor of ice cream but you couldn't. It would perhaps be disappointing but it wouldn't really strongly affect anyone in any way.
What if it was something with a much greater impact such as the ability to "smell" radiation gas which could poison you. That would really means something in a nuclear winter type world.
What if aliens came down and perhaps they could see all of the spectrum of EMR. Would we be disabled then? because all along this spectrum existed and we, by nature or our body and mind, are unable to perceive them and yet theses alien beings are. Would we really be disabled for not having something that we have lived without for the most of our history?
