Somewhere in the ocean lies a small island populated by two small villages of peaceful locals. This is a strange island, and while providing all the needs of the two villages, the ground is nothing but dirt and sand, there is no grass to be found on the entire island. One day, a ship sailing past noticed the small island was not located on any map they had, so they decided to chart it out. As they sailed closer to the island, they noticed the two villages, and the Captian decided to visit the North most village while he sent his First Mate to the South most village.
Upon arrival, the Captian was astonished to find that not only did the locals speak a reconizable dialect of English, but that there was no grass on the entire island.
“So there’s no grass on this island, eh?” The Captian enquired.
“Grass?” The northern village’s chief responded, perplexed.
“Yes, grass, a small green plant, grows out of the ground, looks like a blade.”
“No, guess not, very strange.”
The First Mate, on the other hand, was feeling childish, and when he had the same conversation with the Chief of the Southern village, he told them that grass was blue in color, rather then green.
The two men then left the villages alone, and decided not to map the island as there seemed to be nothing of use or value there, and continued on their way.
Later, when the two Village Chiefs had their weekly meeting, they discussed the strange visitors and their stories, and when the topic of the strange blade like plants that grew out of the ground came up, they got into a huge arguement as of what color this “grass” actually was.
Now, considering that neither Chief has the ability to leave the island and see grass in their life time, how would they go about convincing the other which was the correct color?
The correct anwer is that they can’t. They have no basis of fact to back up their opinion or their belief of the color of grass.
Think about that.
