Its a useless 'venture'. Its like trying to pinch a dead person, he can't feel it. This is even worse, because you simply won't find the words to describe in the first place.
hmmmmmmmmm, thats a tough one, its immpossible, stevie wonder 8)for instance, can you describe colour to him? Nope! he can only hear and feel sound and texture,
it depends, like a blind man that is educated before he got blind would still get it when u say its blue red and shits but a natural blind man who got his own at the age of 0, u just need to avoid any discussions that would involve color, hope this help,
