Once upon a time there were six blind men. These blind men had never seen an elephant but they wanted to know what the elephant looked like. So they went near an elephant to find out.
The first blind man fell against the broad side of the elephant. He immediately said. "The elephant must be like a wall." The second blind man got hold of the elephant's tusk. He cried out, "I' m sure the elephant is like a spear. The third blind man happened to take the elephant's trunk in his hand. He said confidently, "The elephant is surely like a snake." The fourth one stretched out his hand and felt the elephant's leg. "It's clear." he said, "The elephant is like a tree trunk." The fifth, by chance, touched the elephant's ear. "I am confident that the elephant is like a fan." The sixth and the last of the blind men felt the elephant's tail. "I tell you." he cried, "The elephant is like a rope."
And so these blind men argued and argued. Each one snid he was right. But actually all were wrong.
The fifth, by chance, touched the elephant's ears. Here 'by chance' means :
