Impossible

Over the weekend, I was reading an article in which someone was trying to describe the impossible. There are many things in each of our lives in which we would equate with "impossible;" however, imagine my surprise at the author's answer: You want to know what impossible is? Try to describe a color to a blind person.

With color, there is no shape, so there is nothing a blind person can touch and feel to associate themselves with.

So, how would you describe blue? or red? or green? You couldn't possibly equate those colors to an object (ocean, fire truck, grass), because that person will have never seen that object.

Think about that for a minute. How would you describe a color to a blind person? I've thought about it all weekend, and I think that this is the most perfect example of impossible.
