There are stories that natives who had never seen a sailing ship did not see the ship when it was approaching them. It was not until an elder of the tribe saw and pointed them out that the rest saw the ships.
There was a scientific expedition which presented photographs to a tribe that had never seen one before and they could not see the photo. To them it was just paper.
When we think about it we have a way of folding what we see into what we know or believe. However, we have also learned from science that our senses cannot see all that could be seen, hear all that could be heard, smell all that could be smelled, and so on.
The world is indeed a different place for the colorblind, the deaf and the handicapped. Perhaps we shouldn't be so certain that the way we see the world is the only way to see it.
Maybe we need to be more tolerant to someone else's viewpoint before dismissing it.
